Furthermore, the wireless communication module can be integrated with the microcontroller.
A power supply 800, which may be a battery such as a rechargeable battery, may be provided in the main body portion 200 of the surface cleaning apparatus for cordless operation. The battery may be a polymer battery or a lithium ion battery, etc. And in one embodiment, the power supply part 800 may be detachably mounted to the main body part 200, and charging may be performed by detaching the power supply part 800 from the main body part 200. In addition, the power supply unit 800 may further include a charging port or a power line, and may be charged through the charging port without detaching the rechargeable battery, or may be operated by a cord through the power line, so that the cord operation may be performed when the cruising power demand is high, and the rechargeable battery may be in a power-off posture (supplied with power through the power line) when the cord operation is performed, or may be charged while supplying power to the surface cleaning apparatus.
In the present disclosure, the power supply part 800 is positioned to be isolated from potential liquid contact, for example, to avoid the influence of leakage of the cleaning liquid storage part 300 and/or the recovery storage part 400 and the like on the power supply part 800. In the present disclosure, the power supply part 800 is disposed at a position above the cleaning liquid storage part 300 and/or the recovery storage part 400 and is disposed in the main body part 200. Preferably, the power supply part may be disposed at a position below the cleaning liquid storage part 300 and/or the recovery storage part 400 and in the main body part 200, and more optionally, in the main body part 200 near the connection part 500, and by this arrangement, the position of the center of gravity of the surface cleaning apparatus may be effectively lowered, thereby relieving the hand pressure of the user. Of course, it will be understood by those skilled in the art that other locations are possible, and it is only necessary to maintain the power supply part 800 at a distance from the location where the liquid leakage may occur.
In the present disclosure, the various components of the surface cleaning apparatus are arranged relative to each other so that the surface cleaning apparatus can be rotated in both directions. Although it is shown in the present disclosure that the movement may be in two directions, those skilled in the art may also set it to move only in the first direction described below.
In which in fig. 5 to 7 a rotation of the surface cleaning apparatus in a first direction (hereinafter also referred to as X-direction) is shown, wherein the first direction is in a plane perpendicular to the surface to be cleaned, which may also be referred to as up-down rotation relative to the surface to be cleaned. For example, fig. 5 shows the surface cleaning apparatus in an upright posture, fig. 6 shows the surface cleaning apparatus in a posture rotated by 30 °, and fig. 7 shows the surface cleaning apparatus rotated to a posture parallel to the surface to be cleaned. Wherein in the first orientation the surface cleaning apparatus (body portion) is rotatable relative to the surface to be cleaned in a range of 0 ° to 120 °, optionally in a range of 0 ° to 95 °, 0 ° to 110 °, and the like. The posture parallel to the surface to be cleaned means that the angle between the main body portion and the surface to be cleaned is 0 ° or substantially 0 ° (e.g., 0 ° to 5 °, etc.).
Fig. 8 to 10 show the rotation of the surface cleaning apparatus in a second direction (hereinafter also referred to as Y-direction) in a plane parallel to the surface to be cleaned, which may also be referred to as left-right rotation relative to the surface to be cleaned. For example, fig. 8 shows the surface cleaning apparatus not rotating in the second direction, fig. 9 shows the surface cleaning apparatus rotating in the second direction, and fig. 10 shows the surface cleaning apparatus not being able to rotate in the second direction.
As shown in fig. 6, the X-axis about which the X-direction rotation is about may be perpendicular to the direction of the page of fig. 6, and the X-direction rotation may be defined by a pivot joint. The Y axis about which the Y direction rotation is about may be perpendicular to the X axis (a direction parallel to the plane of the paper of fig. 6, e.g. the Y axis extends along the main body portion) and the Y direction rotation may be defined by a swivel joint, further the Y axis is optionally perpendicular to the axis of the moving wheel of the cleaning base and/or the axis of the roller brush of the cleaning base. The Y axis may be at an angle (e.g. an acute angle) to the surface on which the surface cleaning apparatus is placed, such as 80 ° to 90 °, preferably around 80 °, when the main body portion is in an upright position, as shown in figure 5, the acute angle being the angle between the main body portion and the cleaning base, that is, the main body portion is inclined in a forward ("left" in figure 5) downward direction. When the main body is rotated so that the surface cleaning apparatus is in an inclined use position, the Y axis will be at an acute angle to the placing surface (surface to be cleaned) on the other side (right side), that is, the main body is inclined in a rearward (right in fig. 5) downward direction.
When the surface cleaning apparatus is in the upright posture, the X-axis is set to a position in which the intersection of the Y-axis and the surface to be cleaned is forward (leftward in the drawing) and when the surface cleaning apparatus is in the inclined posture, the X-axis is set to a position in which the intersection of the Y-axis and the surface to be cleaned is rearward (rightward in the drawing), as viewed from the position in which the user uses the surface cleaning apparatus, as shown in fig. 5 and 6.
The rotation of the surface cleaning apparatus may be defined by the attachment 500 described above. Wherein the connection part 500 may be a separate component and fixed to the lower end of the main body part 200, or the connection part 500 may be a component integrally molded with the main body part 200 and located at the lower end of the main body part 200.
The connection part 500 is used to connect the main body part 200 with the cleaning base 600, the connection part 500 may be a hollow structure, and air, fluid communication, and lines and the like required for power supply and the like between the main body part 200 and the cleaning base 600 such as a floor brush may be implemented through the connection part 500, so that power supply, circulation of air and/or liquid, and the like may be implemented between the main body part 200 and the cleaning base 600 via wires and/or pipes passing through the connection part 500. Furthermore, a flexible hose for sucking dust and recovering liquid may be passed through the connection portion.
As shown in fig. 11, a collection hose for collecting liquid, garbage, and the like can be accommodated in the connection portion 500, and an outlet 506 of the hose can communicate with the collection storage portion. The recovery hose is of a flexible material and can be deformed in response to tilting of the surface cleaning apparatus. In addition, a cleaning liquid supply line 308 may be accommodated, and the cleaning liquid supply line 308 may pass through the connection part 500 and communicate with a corresponding line in the cleaning base 600, thereby sending the cleaning liquid into the cleaning base 600. The cleaning liquid supply conduit 308 may be rigid and not bend as the connection rotates. Further, a liquid detecting device may be further provided at the cleaning liquid supply line 308 for detecting whether the cleaning liquid is supplied to the cleaning base 600, and a detection signal of the liquid detecting device may be supplied to a microprocessor or the like.
According to one embodiment, the connection part 500 may include a universal joint to enable the main body part 200 to be rotated in both directions with respect to the cleaning base 600.
According to one embodiment, the connection part 500 may include a polyaxial joint that may couple the main body part 200 with the cleaning base 600 so as to allow the main body part 200 to rotate in the first and second directions with respect to the cleaning base 600.
As shown in fig. 5, the main body 200 can be pivoted to an upright position (also referred to as a storage position) by the link 500, in which the angle between the main body 200 and the surface of the cleaning base 600 (or the floor surface on which it is placed) is 80 ° to 90 °, preferably around 80 °. In this position, the surface cleaning apparatus is in a self-supporting attitude (also referred to as an upright attitude), that is, the main body portion 200 and the like can be supported by the cleaning base 600, and the upright attitude can be achieved without the aid of other objects.
When the rotation in the X direction is defined by the pivot joint, for example, as shown in fig. 5, the surface of the cleaning base 600 may be provided with one support protrusion 501, and correspondingly, the connection part 500 may be provided with one support fitting 502 (as shown in fig. 6). As shown in fig. 8, the support projection 501 may be formed with a support groove 503, and the support groove 503 is provided corresponding to the support fitting 502, so that when the main body portion 200 is brought to an upright position (for example, between 80 ° and 90 ° with respect to the forward direction), the support fitting 502 is fitted into the support groove 503, and since the cleaning base 600 is placed on the floor, it may form a seat, and due to the abutting action of the support fitting 502 and the support projection 501, the surface cleaning apparatus is brought to a self-supporting posture. The support fitting part 502 and the support convex part 501 also have a releasable locking function, and when the main body part is enabled to be in the upright position, the support fitting part and the support convex part are clamped. When pivoting from the upright position to the main body portion, the user may apply a certain force causing the two to disengage.
When the main body 200 is rotated in the X direction, the support fitting portion 502 and the support boss portion 501 may be disengaged, for example, as shown in fig. 6. After the support fitting portion 502 and the support boss portion 501 can be disengaged, the main body portion 200 can be rotated in the Y direction up to a predetermined angle at which the main body portion 200 can be rotated. For example, fig. 8 shows the body portion 200 rotated to an angle, and fig. 9 shows the body portion 200 rotated in the Y direction at the angle. Here, the predetermined angle may be an angle of 30 ° from the horizontal direction of the surface to be cleaned. Of course, other angles, such as about 20 °, etc., may be provided.
As shown in fig. 7, the main body portion 200 can finally be rotated in the X direction to a position horizontal to the surface to be cleaned, and in the case of a predetermined angle smaller than the above (for example, in the case of less than 30 °). The main body portion 200 may be made incapable of rotating in the Y direction with respect to the cleaning base 600.
The connection portion 500 may be provided with a stopper protrusion 504. The stopper protrusion 504 may be provided on a side of the connection part 500 opposite to the support fitting part 502, and it may be integrally formed with the connection part 500. The limit protrusion 504 protrudes with respect to the surface of the connection part 500, and the limit protrusion 504 may include at least a limit plane 505. The stopper planes 505 may be provided at positions on both sides of the connection part 500. Accordingly, the cleaning base 600 can include an outwardly extending mount 6611. In the present disclosure, the mounts 6611 are two in number and each extend outwardly from the cleaning base 600. The mount 6611 may be used to support two moving wheels. For example, the roller of the moving wheel may be fixed to the extension arm. The two mounting members 6611 are spaced apart by a predetermined distance, wherein the distance may be equal to or slightly greater than the distance between the two limiting planes 505, such that when the main body portion 200 is rotated within a predetermined angular range (e.g., 0 ° to 30 °), the two limiting planes 505 may respectively contact the inner wall surfaces of the two mounting members 6611, thereby limiting the rotation of the main body portion in the Y direction. It should be noted that the mounting member 6611 should not cause any limitation to the rotation of the main body 200 without being in the predetermined angular range.
Further, at least one of the two extension arms may be provided as a hollow structure through which electric wires and/or pipes may be allowed to pass in order to communicate the main body part with the cleaning base.
According to the technical solution of the present disclosure, when the user operates the surface cleaning apparatus in a wide space, since the angle between the main body portion 200 and the surface to be cleaned is not too small (for example, in the case of 30 ° or more), since the mounting member 6611 does not have any influence on the rotation in the Y direction, the user can rotate the main body portion 200 in the Y direction, thereby guiding the cleaning base portion 600 to turn left and right (Y direction). However, when a user desires to operate the surface cleaning apparatus in a narrow or low space (e.g., a sofa bottom or the like), the surface cleaning apparatus cannot enter the narrow or low space without lowering the posture of the main body portion 200, and thus the space will not be cleaned. In the present disclosure, the user may adjust the main body portion 200 to make its posture lower, which enables the main body portion 200 to extend into a narrow or low space. When the attitude of the main body 200 is below the predetermined angle, the user's ability to control the surface cleaning apparatus starts to decline, at which time the Y-direction rotation of the main body 200 relative to the cleaning base 600 is not desired. In this way, the rotation in the Y direction can be restricted by the two stopper planes 505 contacting the inner wall surfaces of the two mounting members 6611, respectively, so that the user cannot perform the left-right guiding.
Further, although not shown in the figures, a pivot portion (e.g., a circular pivot shaft) may be provided on an inner wall surface of the mounting member 6611, and the pivot portion may be rotatably connected to the connecting portion (e.g., connected to a wall surface of the connecting portion, or provided with a corresponding lug on the connecting portion and connected to the pivot portion). Also the inner wall surfaces of the mounting members 6611 on opposite sides may be provided with pivot portions for connection with the connecting portions. By means of the pivot, the surface cleaning apparatus can be made to be rotatable in the X-direction.
Further, in the present disclosure, when the surface cleaning apparatus is in an inclined use position (for example, in a case where an angle with a surface to be cleaned is greater than or equal to 30 °), a rotation angle in the Y direction may be defined, thereby preventing the rotation angle in the Y direction from being excessively large.
Further, the connection part 500 may be detachably mounted with the cleaning base 600. For example, a snap structure may be provided therebetween, such as a mounting hole provided on the connecting portion and a snap projection provided on the cleaning base, the engagement of the two being achieved by fitting the snap projection into the mounting hole, and the disengagement of the two being achieved by pressing the snap projection away from the mounting hole.
In the present disclosure, as shown in fig. 7, when the main body 200 is in the "lying flat" (parallel to the surface to be cleaned) posture, the height of the main body 200 is set to be equal to or less than 120mm, for example, the height may be set to be 100mm to 120mm, or 105mm to 120mm, or the like, and further, the height of the cleaning base 600 is set to be equal to or less than the height of the main body 200. In addition, the width of the cleaning base 600 should be set to be greater than or equal to the width of the main body 200 (the "width" referred to herein means the width of the cleaning base and the main body in a direction perpendicular to the direction of travel of the surface cleaning apparatus (both directions are in a horizontal plane)).
In addition, to facilitate movement of the surface cleaning apparatus by a user when the main body 200 is in a "lying flat" (parallel to the surface to be cleaned) position, parallel rollers 215 may be provided. In the lying position shown in fig. 7, the user can operate the surface cleaning apparatus by holding the handle portion without providing a supporting force to the surface cleaning apparatus, according to the parallel roller 215. The supporting force of the surface cleaning apparatus can be achieved by moving the wheels and the parallel rollers. Thus in the lying position, the user need only apply a towing force to operate the surface cleaning apparatus. In addition, the parallel roller 215 is disposed at a position separated from the center of gravity of the surface cleaning apparatus or the center of gravity of the main body to prevent the surface cleaning apparatus from being tilted. The parallel rollers may be disposed on the main body portion, the handle portion, or the like.
According to the above-mentioned embodiment of the present disclosure, the user can make the main body portion rotate along both the X direction and the Y direction within a certain angle range, and can conveniently realize the guiding of the cleaning base portion, and will restrict the main body portion from rotating in the Y direction within another angle range. This arrangement may allow the user to better operate the surface cleaning apparatus.
As shown in fig. 3, the main body 200 may include a frame body 220 for supporting the cleaning liquid storage 300 and the recovery storage 400, and may also be used for supporting other components, such as a motor, a fan, and the like. For example, on a portion of the frame body 220 that houses the cleaning liquid storage 300 and the recovery storage 400, two housing walls may be provided, and the liquid storage 300 and the recovery storage 400 are housed at least partially in the two housing walls, which may constitute a housing of the surface cleaning apparatus. In the case of two housing walls, the housing walls are provided on opposite sides of the side of the surface cleaning apparatus different from the cleaning liquid storage part 300 and the recovery storage part 400, and extend in the height direction of the surface cleaning apparatus.
The cleaning liquid storage part 300 and the recovery storage part 400 may be disposed on the frame body 220 so as to be located at both sides of the main body part 200. In the present disclosure, the cleaning liquid storage 300 and the recovery storage 400 are optionally located on both left and right sides of the main body portion 200 (with respect to the travel direction of the surface cleaning apparatus, the cleaning path). The thickness of the cleaning liquid storage part 300 may be equal to or less than the thickness of the recovery storage part 400, and the heights of both may be the same or substantially the same. It should be noted that although the cleaning liquid storage unit 300 and the recovery storage unit 400 are mainly described as examples in the present disclosure as being located on both the left and right sides of the main body 200, it is also preferable in the present disclosure that the cleaning liquid storage unit 300 and the recovery storage unit 400 are provided on both the front and rear sides (both the front and rear sides in the cleaning direction) of the main body 200, and in the case of providing on both the front and rear sides, the respective arrangement relationships of the respective components described herein are the same or similar.
In the present disclosure, the cleaning liquid storage part 300 and the recovery storage part 400 may be detachably mounted to the side of the frame body 220, the mounted sides may be opposite sides of the frame body 220, and the thickness of the cleaning liquid storage part 300 and the recovery storage part 400 is set to be less than the width, so that a sufficient capacity may be secured and the height of the main body part 200 may be less than a predetermined height, for example, 120mm, after lying flat.
Fig. 12 and 13 show schematic views of a cleaning liquid storage 300 according to an embodiment of the present disclosure. Fig. 14 shows a schematic view of the cleaning liquid storage 300 with a part of the wall removed. The cleaning liquid storage part 300 is used to store cleaning liquid and is provided to the cleaning base 600 via a pipe. In this context, the cleaning liquid may be one or more of any suitable liquid, including but not limited to cleaning water, concentrated detergent, dilute detergent, mixtures thereof, or the like. In addition, the cleaning liquid can be normal-temperature cleaning liquid or high-temperature cleaning liquid.
As shown in fig. 12 to 14, the cleaning liquid storage part 300 is flat in shape, and includes a cavity constituted by a plurality of wall surfaces so as to contain the cleaning liquid, and the capacity of the cleaning liquid storage part 300 may be set to 500mL or the like. The cleaning liquid storage part 300 may include a handle 301 and a pressing part 302, and preferably the handle 301 and the pressing part 302 are located at an upper position of the cleaning liquid storage part 300. The cleaning liquid storage part 300 can be attached or detached by a user through the handle 301, and specifically, the cleaning liquid storage part 300 can be detached by the user moving downward by pinching the pressing part 302 (having a spring built therein) to disengage the latch member 303 from the groove provided in the main body part. In the present disclosure, although the handle 301 is illustrated as a built-in handle (hidden handle), it may be provided as an outwardly protruding handle by those skilled in the art. As shown in the drawings, the surface of the upper wall of the cleaning liquid storage part 300 is provided as an inclined surface, so that the cleaning liquid storage part 300 can be pushed onto the main body part 200 and fixed to the main body part 200 by the action of the latch member 303 when the cleaning liquid storage part 300 is mounted.
The cleaning liquid storage 300 may be provided with an inlet port 305, and the inlet port 305 may be closed by a cover plate 304. Thus, when the cleaning liquid is supplied to the cleaning liquid storage 300, the cover plate 304 may be opened to input the cleaning liquid through the inlet port 305. The cover plate 304 may then be closed to block the liquid inlet 305, thereby avoiding leakage of cleaning liquid when the surface cleaning apparatus is in use. The cover plate 304 may be pivotable with respect to the wall surface of the cleaning liquid storage 300, for example, the underside of the cover plate 304 may have a pivot axis and the pivot axis is inserted into the wall surface.
In addition, the cover plate 304 is provided with a blocking portion, such as a plunger, in correspondence with the loading port 305, so that the loading port 305 is blocked by the blocking portion upon changing the closure, which at least partly enters the loading port 305. Of course, it will be appreciated by those skilled in the art that other forms of sealing may be used.
At or near the location of the liquid inlet 305, a vent valve may be provided, which may be a two-way vent valve for selectively drawing gas into the cleaning liquid reservoir 300 or exhausting gas from the cleaning liquid reservoir 300 in order to equalize the internal and external pressures of the cleaning liquid reservoir 300. Further, a vent valve may be provided at an upper wall of the cleaning liquid storage 300, and may be spaced a predetermined distance from the loading port 305. When the cover plate 304 is closed, it may cover the loading port 305 and the vent valve. When the gas pressure on the two sides of the two-way vent valve is unbalanced, the vent valve can be deformed instantly, so that the internal and external gas flow is balanced.
According to an embodiment of the present disclosure, the cleaning liquid storage part 300 may further include a filter 306, the filter 306 being disposed at the liquid outlet of the cleaning liquid storage part 300, and the cleaning liquid supplied from the cleaning liquid storage part 300 is filtered through the filter 306 to filter out impurities in the cleaning liquid. An outlet valve 307 may also be provided in communication with the liquid outlet to selectively allow cleaning liquid to flow from the liquid outlet. The outlet valve 307 may be opened to allow the cleaning liquid to be supplied when the cleaning liquid storage part 300 is mounted to the main body part 200, and the outlet valve 307 may be closed to prevent the cleaning liquid from leaking when the cleaning liquid storage part 300 is removed from the main body part 200. A filter 306 may be installed at one side of the lower wall surface of the cleaning liquid storage part 300 and an outlet valve 307 may be installed at the other side, which are the positions of the liquid outlet.
The outlet valve 307 may communicate with the cleaning liquid supply line 308, and the cleaning liquid supply line 308 may be accommodated inside the connection part 500 as described above and communicate with the supply line of the cleaning base 600. In addition, a liquid detecting means may be further provided near the cleaning liquid supply line 308 or the outlet valve 307 for detecting whether or not the cleaning liquid is supplied to the cleaning base 600. The liquid detection device may be any suitable detection device for detecting the presence of cleaning liquid in the cleaning liquid supply line 308. The liquid detection device may be a conductivity sensor and is located in the cleaning liquid supply line 308 to detect the presence of cleaning liquid.
When the liquid detection means detects that there is no liquid, indicating that there is no cleaning liquid in the cleaning liquid storage 300 or that the cleaning liquid storage 300 has been removed, the liquid detection means may provide a signal to the microcontroller, which may provide information to the user through the display. In addition, the liquid detection device may be located inside the cleaning liquid storage portion 300 and used for detecting the liquid level of the cleaning liquid storage portion 300, so that when the liquid level is too low, indicating that no cleaning liquid exists in the cleaning liquid storage portion 300, a signal may be provided to the microcontroller, or when the cleaning liquid storage portion 300 is removed from the main body portion 200, the electrical connection of the liquid detection device is disconnected, and the microcontroller may also know that the cleaning liquid storage portion 300 is removed.
The input from the liquid detection means may further be used by the microcontroller in order to determine a suitable shut down or otherwise interrupt the supply system of cleaning liquid. The microcontroller may shut down or prevent activation of at least one electrical component of the surface cleaning apparatus, for example when cleaning liquid is not present in the cleaning liquid store 300 or when it is removed. The electrical components may include pumps, valves, various motors, etc., which may stop operation of the surface cleaning apparatus.
In the case where the surface cleaning apparatus is in the lying posture, the height of the cleaning liquid storage 300 may be set to be significantly larger than the width thereof, and the liquid outlet of the cleaning liquid storage 300 may be set at a lower position (right position in fig. 14) of the lower wall surface of the cleaning liquid storage 300.
Fig. 15 to 18 show schematic views of a recycling storage section 400 according to one embodiment of the present disclosure. In which fig. 15 shows a schematic view of the recycling storage 400 at one angle, fig. 16 shows a schematic view of the recycling storage 400 at another angle, fig. 17 shows an exploded view of a part of the recycling storage 400, and fig. 18 shows an exploded view of the recycling storage 400.
As shown in fig. 15 to 18, the recovery storage part 400 includes a cavity constituted by a plurality of wall surfaces so as to accommodate the recovery liquid. The recovery storage part 400 may include a second handle 401 and a second pressing part 402, and preferably the second handle 401 and the second pressing part 402 are located at an upper position of the recovery storage part 400. The user can mount or remove the recovery storage part 400 through the second handle 401, and specifically, the user can remove the recovery storage part 400 by kneading the second pressing part 402 (having a spring built therein) to move it downward to disengage the second latch 403 from the groove provided in the main body part. In the present disclosure, although the second handle 301 is illustrated as an outwardly protruding handle, it may be provided as a built-in handle (hidden handle) by those skilled in the art. As shown in the drawings, the surface of the upper wall of the recovery storage part 400 is provided as an inclined surface, so that the recovery storage part 400 can be pushed onto the main body part 200 and fixed to the main body part 200 by the action of the second latch 403 when the recovery storage part 400 is mounted.
The underside of the recovery storage 400 may be provided with an inlet 404, which inlet 404 may communicate with an outlet 506 of a hose, so that recovered solid waste or recovered liquid enters the recovery storage 400 through the inlet 404.
Further, a liquid level detection portion 405 may be further provided in the recovery storage portion 400, wherein the liquid level detection portion 405 may be provided in plurality so as to detect both the liquid level of the internal recovery liquid when the recovery storage portion 400 is in the upright posture and the liquid level of the internal recovery liquid when the recovery storage portion 400 is in the horizontal posture, which will be described later in detail.
According to one embodiment of the present disclosure, the recycling storage part 400 may include two parts: a first storage section 406 and a second storage section 407. Wherein the first memory portion 406 and the second memory portion 407 are separable. When it is necessary to remove the garbage and the recovery liquid from the recovery storage part 400, the first storage part 406 and the second storage part 407 may be separated. When the first storage portion 406 and the second storage portion 407 are joined together, a seal may be provided therebetween to ensure that the recovered liquid does not leak or the like.
As shown in fig. 17 and 18, the top wall of the first storage portion 406 may be provided with an exhaust port 408, the exhaust port 408 providing a passage port through which gas during suction by the surface cleaning apparatus is exhausted from the surface cleaning apparatus. A gas filtering assembly, which may be any suitable form of filter such as a HEPA filter, for example, may also be provided outside of the exhaust port 408. The gas filter assembly may be disposed in first reservoir 406 or in body portion 200 above first reservoir 406. For example, where the gas filter assembly is disposed in the body portion 200, the gas filter assembly may be disposed adjacent the exhaust port 408 and receive gas from the exhaust port 408. For example, a filter assembly receiving part may be provided at a corresponding position of the main body part 200, and the gas filter assembly may be detachably mounted thereto.
The gas filtration assembly may include a filter media supported on a support, which in one embodiment may be a pleated filter media, and may be made of a material that remains porous when wet. The air filter assembly may further include a mesh screen carried by the frame and disposed on the air upstream side of the filter media for filtering large particles of material. The gas filter assembly may be designed as a unitary assembly for removal from the filter assembly receiver for replacement, etc.
A gas-liquid separation device 420 may be accommodated in the first storage part 406, wherein the gas-liquid separation device 420 may include a gas-liquid separation motor 421 and a gas-liquid separator 422. The gas-liquid separator 422 is driven to operate by the rotation of the gas-liquid separating motor 421, so that the recovered gas and liquid are separated from each other, the liquid is left in the recovery storage part 400, and the gas is discharged from the surface cleaning apparatus after being filtered.
In one embodiment of the present disclosure, the rotating shaft of the gas-liquid separation motor 421 may be coupled with the first timing pulley 423, and the second timing pulley 424 is coupled with the first timing pulley 423 through a timing belt 425, such that when the gas-liquid separation motor 421 rotates, the second timing pulley 424 rotates accordingly. The second timing pulley 424 and bearings 426 are coupled to a drive shaft 427, and the drive shaft 427 is used to drive the gas-liquid separator 422 for rotation.
In one embodiment, the reclamation store 400 may also include a filter 430. The filter 430 will be described in detail with reference to fig. 19 to 21, in which the opposite arrangement of the filter 430 and the gas-liquid separation device 420 is shown in fig. 20 and 21. The filter 430 may include a solid storage portion 431, a conduit passing port 432, a filtering portion 433, a second anti-surge portion 434, and a first anti-surge portion 435.
The solid receptacle 431 can be used to store solid waste, such as debris, hair, etc., recovered during cleaning. The solid storage part 431 at least comprises a bottom wall 4311, a first side wall 4312 and a top wall 4313, wherein the bottom wall 4311 and the first side wall 4312 are provided with liquid guide holes, so that the recovered liquid flows out from the solid storage part 431 to the cavity of the recovery storage part 400, and only the solid garbage is left. Wherein the liquid guiding hole is dimensioned to allow only liquid or liquid and fine debris to pass through. The solid storage part 431 may further include an open part so that the solid garbage can be discharged through the open part when the user cleans the solid garbage. A conduit pass-through port 432 may be provided in the bottom wall 4311, the conduit pass-through portion 432 allowing a recovery conduit (not shown) to pass therethrough, wherein the recovery conduit communicates with the inlet port 404 of the liquid storage portion 400 to direct recovered liquid or solids or the like to the filter 430 when the surface cleaning apparatus is in operation.
Additionally, the solids reservoir 431 may further include a second side wall 4314 and a third side wall 4315, wherein the second side wall 4314 and the third side wall 4315 are oppositely disposed and extend between the bottom wall 4311 and the top wall 4313. In the present disclosure, the second and third side walls 4314 and 4315 are provided only at partial positions between the bottom wall 4311 and the top wall 4313, and the positions not provided may be the above-described open portions. The solid storage part 431 may further include a fourth side wall 4316, the fourth side wall 4316 extending upward from the bottom wall 4311, but it does not extend to the top wall 4313, but is provided to extend only a distance, so that a space for containing the solid may be formed by the fourth side wall 4316, the second side wall 4314, the third side wall 4315 and the bottom wall 4311, and it is also possible to facilitate the cleaning of the garbage through the open part. End faces of the fourth side wall 4316, the second side wall 4314, the third side wall 4315, and the top wall 4313 may be provided to fit an inner wall of the recovery storage part 400.
A space, which may be shaped like an L and opened on the top wall 4313 adjacent to the first side wall 4312, is opened on the top wall 4313 and a filter net (not shown) is detachably mounted to constitute the filter part 433. Further, a conduit support part 436 may be provided on the top wall 4313, and the conduit support part 436 extends a predetermined length toward the inside of the solid storage part 431 so as to support an end (open end) of the recovery conduit. Further, after supporting the end of the recovery conduit, the open end of the recovery conduit may be directed toward the top wall 4313 and spaced a distance from the top wall 4313. As shown in fig. 20, since the top wall 4313 is provided between and separates the open end of the recovery conduit and the gas-liquid separator 422, the recovery liquid from the open end of the recovery conduit can be prevented from reaching the gas-liquid separator 422 by the blocking action of the top wall 4313. When the recovered liquid with entrained solids enters the space formed by the solids reservoir 431 through the recovery conduit, the solids are retained in the space of the solids reservoir 431 by the filter 433 in the form of a screen or the like, and only the liquid is allowed to enter the space where the gas-liquid separator 422 is located through the filter 433, so that the solids are retained in the solids reservoir 431.
The second anti-surge portion 434 is provided in the form of a partition plate, and one or more liquid through holes are opened in the partition plate so as to allow the recovery liquid to pass therethrough, prevent the rapidly changing liquid from being waved in the recovery storage portion 400 by the blocking action of the partition plate when the recovery liquid passes therethrough, and allow the liquid in the spaces on both sides of the second anti-surge portion 434 to be communicated through the liquid through holes.
For example, when the surface cleaning apparatus is changed from the upright posture to the inclined use posture, or the parallel posture (lying posture), or from the inclined use posture to the parallel posture, the recovered liquid stored in the recovery storage part 400 will generate waves due to the change in the angle of the surface cleaning apparatus, and the liquid may enter the gas-liquid separator 422 if the waves are not suppressed. The waves can be blocked by the partition of the second anti-surge portion 434, and the liquid can also flow through the liquid through holes provided in the partition. At least one (for example, three) end surfaces of the second surge protector 434 may be attached to the inside of the collection storage unit 400.
Further, the opening area occupied by the filter portions 433 may be set to be larger than or equal to the opening area occupied by the liquid passing hole or holes provided by the second surging-prevention portion 434 (for example, the total opening area occupied by the two filter portions 433 may be set to be larger than or equal to the total opening area occupied by the liquid passing holes), so that air is mainly taken from the position of the filter portion 434 toward the gas-liquid separator 422 at least when the surface cleaning apparatus is in the parallel posture. Thus, when viewed in the parallel posture, the liquid is prevented from reaching the gas-liquid separator 422 from the lower portion of the first surging prevention part 435 through the first surging prevention part 435, affecting the gas-liquid separation effect of the gas-liquid separator 422.
The first anti-surge portion 435 is disposed opposite the gas-liquid separator 422, and optionally, a central axis of the first anti-surge portion 435 and a central axis of the gas-liquid separator 422 are parallel to or coincide with each other, and it is preferable in the present disclosure that both central axes coincide with each other (as shown in fig. 20). The central axis of the gas-liquid separator 422 may be an axis at which the center of the drive shaft thereof is located, and the central axis of the first surging prevention part 435 may be a central axis of a hollow portion of the first surging prevention part 435 mentioned below.
As shown, the first anti-surge portion 435 may include an edge portion 4351, a transition portion 4352, and a hollow portion 4353. The transition portion 4352 is located between the edge portion 4351 and the hollow portion 4353. From the plane in which the edge portion 4351 lies, the transition portion 4352 extends obliquely to the hollow portion 4353, such that the transition portion forms an inclined plane between the edge portion 4351 and the hollow portion 4353. When the surface cleaning apparatus mounted with the recovery storage section 400 is viewed in a parallel posture, the inclined direction of the transition portion 4352 is a downward direction, and the inclined direction of the transition portion 4352 is a direction away from the gas-liquid separator 422.
So that the liquid in the space where gas-liquid separator 422 is located can enter first anti-surge portion 435 and slide down transition portion 4352. Further, due to the shape arrangement of the first surging prevention part 435, when the surface cleaning apparatus is changed from the upright posture to the inclined use posture, or the parallel posture (lying posture), or from the inclined use posture to the parallel posture, it is also possible to cancel out the waves generated by the angle change by the first surging prevention part 435 due to the angle change of the surface cleaning apparatus, thereby preventing the liquid from entering the gas-liquid separator 422 due to the waves.
Furthermore, when the surface cleaning apparatus (accordingly, the recovery storage portion 400) performs attitude change between the inclined use attitude and the parallel attitude, a wave may be formed between the first chamber and the fourth chamber, and the wave may affect the open end of the recovery duct 440 and even the gas-liquid separator 422. To avoid these effects, the bottom wall 4311 may serve as a third surge prevention portion, wherein when a wave contacts the bottom wall 4311, the wave may be counteracted by the avoidance of the bottom wall 4311, and fluid communication between the first and fourth chambers is achieved through the liquid guide hole of the bottom wall 4311. In an alternative embodiment, the first side wall 4312 may also serve as a third surge protection portion, and the principle of implementation is the same as that of the bottom wall 4311, and thus the description thereof is omitted.
Therefore, according to the above mode of the present disclosure, a three-stage anti-surge function can be realized, so as to avoid a large amount of liquid from entering the gas-liquid separator 422.
As described above, when a user needs to clean the trash in the filter 430, it can be taken out of the recycling storage part 400, so that the first anti-surge part 435 can be used as a hand-held part for the user to take out the filter 430. When the first storage part 406 and the second storage part 407 are separated, a user can access the filter 430 received therein through the opening of the second storage part 407 and then take out the filter 430 by holding the first anti-surge part 435. In an alternative embodiment, when filter 430 is installed in second storage portion 407, first anti-surge portion 435 protrudes outward relative to second storage portion 407 for gripping by a user.
In the present disclosure, the filter 430 may be integrally formed or fixedly provided, and as shown in fig. 20, the extending axes of the top wall 4313 and the second surge protector 434 coincide, or may be one plate-shaped portion, and the solid storage 431 is located at one side of the plate-shaped portion, while the first surge protector 435 is located at the other side of the plate-shaped portion. The first surging-prevention portion 435 may be fixed to the top wall 4313 or integrally formed with the top wall 4313 or the like, and with respect to a central axis of the solid storage portion 431 (a central axis extending in the height direction of the recovery storage portion 400 in the upright posture), an extending direction of the first surging-prevention portion 435 is deviated from the central axis so as to lift the filter 430 and provide a larger arrangement space to the filter portion 433.
The inner cavity of the recycling storage part 400 may be divided into a first cavity, a second cavity, and a third cavity according to a space formed by the filter 430 and the case of the recycling storage part 400. Wherein, the first cavity is a space formed by the second anti-surge part 434 and the first side wall 4312; the second cavity is a space formed by the first anti-surge part 435 and the second anti-surge part 434; the third cavity is a space formed by the first anti-surge part 435 and the top wall 4313, namely a space where the gas-liquid separator 422 is located; the fourth cavity is a space where the solid storage part 431 is located.
The formation of waves in the second chamber is prevented by the second anti-surge portion 434 when the liquid flows from the first chamber to the second chamber, and the formation of waves in the third chamber is prevented by the first anti-surge portion 435 when the liquid flows from the second chamber to the third chamber.
Fig. 22 shows an oblique cross-sectional view of the recovery storage section 400. Fig. 23 shows a partial sectional view of the recovery storage part 400.
Fig. 22 and 23 are schematic views showing the recovery storage unit 400 in a parallel posture. It should be noted that although the parallel posture is taken as an example for explanation, the principle is the same in the case of the inclined use posture and the upright posture, and the description is omitted.
In the present disclosure, a suction source 460 (shown in FIG. 3) may be disposed in the recovery flow path to suction the recovered liquid, gas, and/or solids, wherein the suction source may be disposed downstream of gas-liquid separator 422. Wherein the suction source may be disposed in a housing, and the housing may include a suction motor housing that may house the suction motor and a fan housing that may house the fan. Alternatively, both may be provided in one housing. The fan housing may comprise a gas inlet to draw gas into the fan housing, and the gas inlet may be substantially aligned with a central region of the fan, which may be the central axis of the motor, for example. The fan housing may further comprise a gas outlet through which gas is discharged. The suction motor may be a brushless dc motor and may be powered directly by rechargeable batteries. In the case of supplying power by a wired method, an ac/dc conversion part may be provided in the control circuit part to convert ac power into dc power to supply to the motor, thereby realizing long-endurance washing.
The suction source 460 is provided at a position separate from the recovery storage part 400, and may be provided in the upper case 210 of the main body part 200, for example. Wherein the upper housing 210 and the frame body 220 may be detachably mounted or integrally formed. A power supply part 800 such as a rechargeable battery and a control circuit part 700 may also be accommodated in the upper case. In addition, a sound device 900 is provided at a side of the upper case 210, and the sound device 900 may be connected to the control circuit part 700 so as to emit a sound through the sound device 900 to prompt a user or the like.
Recovered liquid, gas and/or solids are drawn through the recovery conduit 440 and into the fourth chamber where solids (e.g., solid waste other than debris) will reside in the solids reservoir 431. Some or all of the liquid can flow into the first cavity through the liquid-conducting holes in the bottom wall 4311 and/or the first side wall 4312, and gas, liquid and/or vapor (and possibly also debris that is not filtered through the filter portion) will pass through the filter portion 433 into the third cavity, where the filter portion 433 functions to block solids and allow liquid and gas (possibly with some debris entrained) to pass through. In the third cavity, the gas and liquid are separated by the gas-liquid separator 422 so that the gas passes through and is discharged along the passage, leaving liquid (possibly with debris) in the third cavity (the liquid and/or small particle trash is thrown away in the third cavity by the rotation of the gas-liquid separator 422). In the parallel posture or the inclined use posture of the recovery storage part 400, the liquid of the third cavity may enter the second cavity through the hollow portion of the first surging-prevention part 435. And the first and second cavities may be in fluid communication through the liquid through-hole of the second surging prevention part 434, wherein the liquid of the third cavity may flow into the fourth cavity through the filtering part 433 and then flow into the first cavity from the fourth cavity in the upright posture or the inclined use posture of the recovery storage part 400.
The flow path of the gas is shown by arrows in fig. 22, in which the gas enters the recovery conduit 440 from the inlet port 404, merges into the first chamber along the recovery conduit 440, then flows into the second chamber via the filtering portion 433, is separated by the gas-liquid separator 422, and then is discharged from the gas outlet 408 through the gas passage.
The recovery conduit 440 (or its central axis) is disposed offset from the longitudinal central axis of the recovery storage 400 and may be parallel to the longitudinal central axis. It is provided that the recovery duct 440 is closer to the main body portion or closer to the cleaning liquid storage portion 300 than the longitudinal central axis in a posture of being mounted to the recovery storage portion 400. In the present disclosure, the position of the recovery duct 440 may be disposed near the upper side of the recovery storage part 400 when the recovery storage part 400 is in the parallel posture, and in a case where the recovery storage part 400 is in the upright posture or the inclined use posture in another view, the position of the recovery duct 440 may be disposed near the front side of the recovery storage part 400. Also, in alternative embodiments of the present disclosure, the recovery duct 440 may be fixed to the wall of the recovery storage part 400 or integrally formed with the wall. This prevents liquid from the recovery storage portion 400 from entering the recovery conduit 440 when the surface cleaning apparatus is in a parallel position (lying flat). The level of the liquid in the recovery storage portion 400 may also be made lower than the open end of the recovery conduit 440 to prevent the recovery liquid from entering the recovery conduit 440 when the surface cleaning apparatus is in an upright or inclined use attitude.
As shown in the enlarged part a of fig. 23, in order to prevent liquid or moisture or the like from leaking from the third chamber into the gas passage to deteriorate the gas-liquid separation effect, a labyrinth structure may be provided at a connecting portion of the third chamber and the gas passage, wherein the labyrinth structure may include a first baffle 451, a second baffle 452, and a third baffle 453, wherein the first baffle 451 may be disposed at an upstream position, the second baffle 452 may be disposed at a midstream position, and the third baffle 453 may be disposed at a downstream position in a direction from the third chamber to the gas passage. The first baffle 451 and the third baffle 453 may be provided on the support (or the wall thereof) of the recovery storage unit 400, and the second baffle 452 may be provided on the gas-liquid separator 422 (e.g., the casing of the gas-liquid separator 422). When the collection storage part 400 is in the parallel posture, the extending direction of the first flap 451 and the third flap 453 is downward, and the extending direction of the second flap 452 is upward. Thus, the first barrier 451, the second barrier 452, the third barrier 453, the support (or the wall body) of the recovery storage part 400, and the housing of the gas-liquid separator 422 may constitute a three-stage labyrinth structure, so that liquid, moisture, or the like may be prevented from entering the gas passage. In one embodiment of the present disclosure, the liquid level detection portion 405 may be used to detect the liquid level of the liquid in one or more postures in the recovery storage portion 400, for example, the liquid of the recovered liquid in at least one of a parallel posture, a self-supporting state, and a parallel posture and a self-supporting state may be detected.
The first threshold limit level of the level detection means is set to: when the recovery storage part is in a parallel posture, the liquid level is a first preset distance away from the gas-liquid separator, so that the non-recovery storage part is prevented from exceeding a first limit liquid level threshold value. Preferably, the height at which the first anti-surge portion is located or a height below the height is set as the first limit liquid level threshold value. Preferably, a height at or below which the lowest point of the first anti-surge portion is located is set as the first limit liquid level threshold value. The second limit level threshold of the level detection means is set to: when the recovery storage part is in a vertical posture parallel to the horizontal posture, the liquid level is a second preset distance away from the gas-liquid separator so as to prevent the recovery storage part from exceeding a second limit liquid level threshold value. Preferably, the height at which the second anti-surge part is located or below is the second limit liquid level threshold. The liquid level detection device comprises more than two liquid level detection parts, and at least two liquid level detection parts are arranged on the liquid level height of the first limit liquid level threshold; more preferably, the liquid level detection section is arranged below the liquid level height of the first limit liquid level threshold. Optionally, the liquid level detection device includes more than two liquid level detection portions, and at least two liquid level detection portions are disposed at the liquid level height of the second limit liquid level threshold. Optionally, the liquid level detection device includes two or more second liquid level detection portions, and one or more liquid level detection portions are disposed at a liquid level height of the second limit liquid level threshold; more preferably, one or more second liquid level detection portions are provided below the liquid level height of the second limit liquid level threshold. Further, it is noted that the first liquid level detection section may be multiplexed with the second liquid level detection section. Through the setting of these first liquid level detection portion and second liquid level detection portion, can carry out accurate detection in corresponding gesture respectively to avoid rocking the detection interference that brings because of liquid.
Furthermore, in the case where the liquid level in the recovery storage portion 400 is obtained, it is also possible to control whether or not to interrupt the recovery system, thereby shutting down the surface cleaning apparatus or the like, in accordance with the detected liquid level. The liquid detection portion 405 may be any suitable detection device or element or the like. In the present disclosure, the liquid level detection part may be in the form of a sensor, for example, may be in the form of a metal probe sheet. The following description will take the example of a metal probe, but it will be understood by those skilled in the art that other detection means may be used.
The metal probe sheet may be provided on the inner side surface or the outer side surface of the recovery storage unit 400, and preferably may be provided on the outer side surface of the recovery storage unit 400. And it is more preferable in the present disclosure to dispose the metal probe sheet on the side of the recovery storage part 400 toward the frame body. The number of the metal probe pieces may be set to two or other numbers, and the number of the metal probe pieces is selected so that the level of the recovered liquid can be detected at least in the upright posture and the parallel posture, and more preferably also in the inclined use posture.
According to an embodiment, as shown in fig. 24 and 25 (fig. 24 shows a schematic view of the recovery storage part 400 in an upright posture, fig. 25 shows a schematic view of the recovery storage part 400 in a parallel posture), four or more liquid level detection parts (metal probes) may be provided, and the four or more liquid level detection parts may be provided in a row-column manner, for example, in the case of four as shown in the drawing, the four liquid level detection parts may be provided in two rows and two columns. Although the arrangement is described here, it may be an irregular shape.
For example, when the liquid level of the recovered liquid is detected in the upright posture, the height of the liquid level can be obtained by the liquid level detection portions in the two rows. Of course, it will be understood by those skilled in the art that more level detection sections may be provided to achieve greater accuracy. For example, when the liquid level of the recovery storage unit 400 in the upright posture is measured, the liquid level measurement may be performed by a set of liquid level detection units arranged in the height direction of the recovery storage unit 400. Further, the uppermost liquid level detection means may be provided at a capacity threshold position of the recovery storage portion 400 to prevent liquid from exceeding the threshold height, and when the threshold height is reached, the surface cleaning apparatus may alarm to remind the user of the treatment.
When the liquid level of the recovered liquid is detected in a parallel posture, the height of the liquid level can be obtained by the two rows of the liquid level detecting parts. For example, when the liquid level of the recovery storage unit 400 in the upright posture is measured, the liquid level measurement may be performed by a set of liquid level detection units arranged along the thickness direction of the recovery storage unit 400. Alternatively, the uppermost liquid level detection means may be provided at a capacity threshold position of the recovery storage portion 400 to prevent liquid from exceeding the threshold height, and when the threshold height is reached, the surface cleaning apparatus may alarm to alert the user to the treatment. For example, the threshold height may be a height below the open end of the recovery conduit (whether in an upright position, an inclined use position, or a parallel position).
In addition, when the liquid level of the recovered liquid is detected in an inclined use posture, the detection may be performed by liquid level detection devices arranged in a row.
Furthermore, the fluid level detection means may also be used to detect whether the recovery storage portion 400 is present on the surface cleaning apparatus. For example, the liquid level detection device may cooperate with a sensing device disposed on the frame of the main body 200, e.g., in the presence of a mutual sensing signal, the recycling storage portion 400 is considered to be present on the surface cleaning apparatus.
Continuing with the example of the metal probe sheet, the metal probe sheet is disposed on a side surface of the recycling storage portion 400 facing the frame body, and a conductive sheet may be disposed on the frame body, and when the recycling storage portion 400 is mounted, the conductive sheet may supply power to the metal probe sheet, so that the metal probe sheet can detect the liquid level and/or the existence of the recycling storage portion 400. Although a metal probe and a conductive strip are illustrated, it should be understood that the two may take any other suitable form.
In addition, the liquid level detection unit and the detection unit for detecting whether the recovery storage unit 400 exists may be separately provided, that is, independent detection methods may be used for the two functions. In addition, two or more sets of detection units may be provided to realize two kinds of detection functions.
Further, as shown in fig. 26, an electric wire housing part 230 may be further provided in a space between the cleaning liquid storage part 300 and the recovery storage part 400. The electric wire accommodation portion 230 may be provided in the frame body 220, and may be fixed to the frame body 220, for example. The electric wire housing part 230 may extend from the entire height of the cleaning liquid storage part 300 and the recovery storage part 400, or from the lower ends of the cleaning liquid storage part 300 and the recovery storage part 400 to the vicinity of the control circuit part 700 and/or the power supply part 800.
The electric line accommodation part 230 may have a long bar shape having a groove, and a power supply line, a control line, and the like may be accommodated in the electric line accommodation part 230, thereby achieving electrical communication with the cleaning base 600.
In addition, as an alternative embodiment, a receiving portion in the form of a groove or the like may be provided on the frame body 220 as the electric wire receiving portion 230. The conductive sheet may be provided on the electric wire housing part 230.
In the present disclosure, the detection portion of the liquid level detection device is located near the rear of the surface cleaning apparatus relative to the recovery conduit. The detection portion of the liquid level detection device is one or more detection portions arranged from the outlet of the recovery conduit to the rear portion of the surface cleaning apparatus so as to be able to detect the liquid level of the recovered liquid of the recovery storage portion when in at least one of the intermediate postures of the parallel posture and the self-supporting posture. The detection unit communicates between the inside and the outside of the collection box, and may penetrate through a wall of the collection storage unit, for example. As shown, the detection portion may include a first arrangement and a second arrangement, the first arrangement and the second arrangement being arranged along a longitudinal direction of the surface cleaning apparatus. Preferably, the first array comprises at least a first probe point and a second probe point, the second array comprises at least a third probe point and a fourth probe point, and the first probe point and the fourth probe point can be electrically communicated with each other. When the robot is in a parallel posture, the first probe point is communicated with the third probe point or the second probe point is communicated with the fourth probe point; and when the device is in a vertical posture and/or a self-supporting posture, the first probe point is communicated with the second probe point or the third probe point is communicated with the fourth probe point.
As the surface cleaning apparatus performs a suction operation, a downstream located suction source 460 performs a suction operation, drawing gas from the exhaust port 408 and then out of the surface cleaning apparatus. Upstream of the suction source 460 is a recovery storage portion 400, and a recovery duct 440 in the recovery storage portion 400 receives recovered substances such as recovered liquid, gas, and solids sucked from the cleaning base 600 from an outlet 506, and the recovery duct 440 introduces the recovered substances into the recovery storage portion 400, the liquid and the solids remain in the recovery storage portion 400, and the gas is discharged from the gas outlet 408 through a gas passage by the gas-liquid separator 422. Furthermore, one or more additional filters can be arranged in the gas channel. For example, additional filters may be provided downstream of the suction source 460 and/or between upstream thereof and the recovery storage 400.
Figure 27 shows a schematic view of a cleaning base according to one embodiment of the present disclosure. Fig. 28 shows a schematic view of another angle of a cleaning base according to an embodiment of the present disclosure. Fig. 29 shows an internal structural schematic of a cleaning base according to one embodiment of the present disclosure.
The surface cleaning apparatus of the present disclosure may include a cleaning base 600 as shown in fig. 27. The cleaning base 600 can be used as a cleaning component of a surface cleaning apparatus.
The cleaning base 600 according to an embodiment of the present disclosure, as shown in fig. 27 to 29, includes: a cleaning module 610, the cleaning module 610 comprising a cleaning surface that is drivable to make surface contact with a surface to be cleaned; a fluid distribution module 620, the fluid distribution module 620 being used to provide a predetermined amount of cleaning liquid to the cleaning module 610 to provide the cleaning liquid to the surface to be cleaned by the movement of the cleaning surface of the cleaning module 610, so that the cleaning base 600 performs wet cleaning on the surface to be cleaned; and a soil suction module 630, the soil suction module 630 being provided with a negative pressure for collecting and sucking soil (e.g., dust and hair, etc.) after the cleaning module 610 cleans the surface to be cleaned into the soil suction module 630, thereby preventing the cleaning base 600 from leaving stains such as used cleaning liquid on the surface to be cleaned after cleaning the surface to be cleaned. Of course, the surface cleaning apparatus is also capable of dry cleaning a surface to be cleaned when the fluid dispensing module 620 is not providing cleaning liquid to the cleaning module 610.

In particular, the cradle portion includes a mechanical connector corresponding to the housing module, which is simultaneously aligned with a mating connector of the housing module when the cradle portion is accessed into the housing module mated therewith. And the bracket portion 618 is connected to at least the first rotating portion, and when the bracket portion is mounted to the housing module, at least a portion of the cleaning drive device slides into the first rotating portion; more specifically, when the bracket portion is mounted to the housing module, the transmission slides into the first rotating portion cavity and mechanically couples the transmission and the first rotating portion.
As shown in fig. 30 and 31, when the cleaning module 610 includes only the first rotating part 6111 and the ring 6112 disposed outside the first rotating part 6111, the cleaning module 610 is formed in the form of a roll brush. As shown in fig. 32 and 33, the cleaning module 610 may also be formed in the form of an endless belt type cleaning device, in which case the cleaning module 610 further includes a second rotating part 6113, the second rotating part 6113 is disposed in parallel with the first rotating part 6111, and one end of the second rotating part 6113 is also rotatably disposed at the housing module 650.
The ring-shaped member 6112 is disposed to wrap the first rotating portion 6111 and the second rotating portion 6113, and the ring-shaped member 6112 located below the first rotating portion 6111 and the second rotating portion 6113 is brought into contact with the surface to be cleaned.
The outer diameters of the first rotating portion 6111 and the second rotating portion 6113 may be the same or different. When the outer diameters of the first rotating portion 6111 and the second rotating portion 6113 are different, the diameter of the first rotating portion 6111 is preferably larger than the diameter of the second rotating portion 6113.
The cleaning surface is located on the ring-shaped member 6112, and the ring-shaped member is used for power transmission between the first rotating portion 6111 and the second rotating portion 6113.
The second rotating part 6113 is arranged in front of the first rotating part 6111 by taking the moving direction of the surface cleaning device for cleaning the surface to be cleaned as the front direction, namely, the first rotating part 6111 is close to the rear side of the cleaning module, and the second rotating part 6113 is close to the front side of the cleaning module; of course, the second rotating portion 6113 may be disposed behind the first rotating portion 6111, and a person skilled in the art can adjust the position of the second rotating portion 6113 according to his or her technical knowledge.
As shown in fig. 32 and 33, further, the other end of the second rotating portion 6113 is also rotatably provided to the bracket portion 618, so that the first rotating portion 6111 and the second rotating portion 6113 are rotatably supported by the bracket portion 618. Here, when the cleaning module 610 includes the first rotating portion 6111 and the second rotating portion 6113, that is, the cleaning module 610 is formed as an endless belt type cleaning device, the endless member 6112 is formed as a flexible endless belt portion.

Accordingly, when the cleaning driving device 612 is located inside the first rotation portion 6111, since there is no transmission member such as a timing belt, the edgewise distance of the cleaning base 600 is reduced to be smaller. For example, as shown in fig. 34, the value of the edgewise cleaning distance X depends only on the thickness of the bracket portion 618, and the value of the edgewise cleaning distance Y depends only on the thickness of the mounting portion 651, so that it is not necessary to mount a timing belt, and it is prevented that the mounting of a wide timing belt deteriorates the welting performance.
The cleaning drive 612 is fixed to the mounting portion 651, and the speed change device 615 may be connected to the cleaning drive 612, but the speed change device 615 may not be used when the cleaning drive 612 is selected to be a speed reduction motor, and the power of the cleaning drive 612 is directly transmitted to the first drive connecting member 616.
The transmission 615 is connected to the first drive connection 616 to transmit drive to the first drive connection; also, the first driving connecting part 616 is drivingly connected to the second driving connecting part 617, and when the second driving connecting part 617 is fixed to the first rotating portion 6111, a driving force can be supplied to the first rotating portion 6111, and thus the first rotating portion 6111 can be rotated.
On the other hand, the first support 6191 is disposed inside the other end of the first rotating portion 6111, for example, the inner wall surface of the first rotating portion 6111 is fixed to the outer wall surface of the first support 6191. Inside the first support 6191, a second support 6192 is provided, said second support 6192 being detachable with respect to the first support 6191, i.e. the second support 6192 can be removed from the first support 6191.
The support portion 6193 is fixed to the second support member 6192 through the bracket portion 618, and a bearing is disposed between the support portion 6193 and the bracket portion 618, so that the support portion 6193 is rotatably supported on the bracket portion 618 through the bearing, and the first rotating portion 6111 can rotate relative to the bracket portion 618.
With a similar structure, both ends of the second rotating portion 6111 can be rotatably disposed at the bracket portion 618 and the mounting portion 651, respectively, and will not be described in detail herein.
Fig. 35 illustrates a schematic structural view of a first rotating part according to an embodiment of the present disclosure. FIG. 36 shows a schematic representation of a ring according to one embodiment of the present disclosure. In order to prevent the ring-shaped member 6112 from being detached from the first rotating portion 6111 and/or the second rotating portion 6113, as shown in fig. 35, at least one end of the first rotating portion 6111 and/or the second rotating portion 6113 is formed with an outer flange portion 6111A, and preferably, both ends of the first rotating portion 6111 and/or the second rotating portion 6113 are formed with outer flange portions 6111A, thereby restraining the ring-shaped member 6112 between the two outer flange portions 6111A.
Further, in order to prevent the ring-shaped member 6112 from slipping on the first rotating portion 6111 and/or the second rotating portion 6113, as shown in fig. 35, an external tooth portion 6111B is formed on the circumferential surface of at least one of the first rotating portion 6111 and/or the second rotating portion 6113; accordingly, the inner circumferential surface of the ring member 6112 is formed with inner teeth, so that slipping of the ring member 6112 is effectively prevented by cooperation of the outer teeth 6111B and the inner teeth, and efficiency of cleaning the surface to be cleaned is improved.
Moreover, in consideration of the large length of the first rotating portion 6111 and/or the second rotating portion 6113, in order to prevent the flexible annular belt portion from being folded, etc., as shown in fig. 35, at least one annular groove 6111C is formed on the outer circumferential surface of the first rotating portion 6111 and/or the second rotating portion 6113 to divide the first rotating portion 6111 and the second rotating portion 6113 into a plurality of portions in the axial direction by the annular groove 6111C.
Further, as shown in fig. 35, at least one of both sides of the annular groove 6111C is provided with an annular projection 6111D, more preferably, both sides of the annular groove 6111C are provided with annular projections 6111D, wherein an internal tooth portion is formed in a region between the two annular grooves 6111C and a region between the annular groove 6111C and the outer flange portion 6111A.
Accordingly, the inner surface of the ring member 6112 forms the annular protrusion 6111D and the annular groove 6111C corresponding to portions of the annular groove 6111C and the annular protrusion 6111D, such that the annular protrusion 6111D of the ring member 6112 is engaged with the annular groove 6111C of the first rotating portion 6111 and/or the second rotating portion 6113, and the annular groove 6111C of the ring member 6112 is engaged with the annular protrusion 6111D of the first rotating portion 6111 and/or the second rotating portion 6113.
Fig. 37 illustrates a structural schematic view of a first rotating part 6111 according to another embodiment of the present disclosure. Fig. 38 shows a schematic structural view of a ring 6112 according to another embodiment of the present disclosure. In the disclosure, in another case, a soft rubber layer 6111E is disposed in an area between the two annular grooves 6111C and/or between the annular groove 6111C and the outer flange 6111A, so that friction between the first rotating portion 6111 and the annular member 6112 is increased through the soft rubber layer 6111E, and relative sliding between the annular member 6112 and the first rotating portion 6111 is prevented. More preferably, the soft rubber layer 6111E may be made of a soft material such as natural or synthetic rubber, for example, Ethylene Propylene Diene Monomer (EPDM) or nitrile rubber, or silicone rubber. On the other hand, the soft rubber layer 6111E may also be provided with an external tooth portion 6111B, so that the relative sliding between the first rotating portion 6111 and the ring-shaped member 6112 is further prevented by the soft rubber layer 6111E with the external tooth portion 6111B.
Fig. 39 shows a cross-sectional schematic of fig. 37. Fig. 40 shows a cross-sectional schematic of fig. 38. As shown in fig. 39 and 40, the radial dimension of the outer flange portions 6111A at the two ends of the first rotating portion 6111 and/or the second rotating portion 6113 of the present disclosure is smaller than the thickness of the ring member 6112, so that when the cleaning module 610 performs a cleaning operation, the outer flange portions 6111A of the first rotating portion 6111 and/or the second rotating portion 6113 do not contact the surface to be cleaned, damage to the surface to be cleaned by the first rotating portion 6111 and/or the second rotating portion 6113 is effectively prevented, and the cleaning effect is also improved.
Considering that the structure of the second rotating portion 6113 of the present disclosure is similar to that of the first rotating portion 6111, a person skilled in the art can know the structure of the second rotating portion 6113 according to the structure of the first rotating portion 6111, and an illustration of the second rotating portion 6113 is not provided based on this disclosure.
FIG. 41 shows a schematic diagram of a process for making an annular part according to one embodiment of the present disclosure. In the present disclosure, the ring 6112 is an important part of the cleaning work, and the flexible ring belt portion is in direct contact with the surface to be cleaned when the surface cleaning apparatus is used for the cleaning work. Preferably, the ring-shaped member 6112 includes a cleaning body 6112A and a base material 6112B, and the cleaning body 6112A is similar to the cleaning body 6112A of a general floor brush, and may be made of a floss material such as a mop. The base material 6112B is generally a flexible soft material, and the cleaning body 6112A can be fixed on the base material 6112B by gluing, sewing or the like, so that the whole ring-shaped member 6112 is attached around the first rotating portion 6111, or attached around the first rotating portion 6111 and the second rotating portion 6113 which are parallel to each other.
In view of the particularity of the ring-shaped member 6112 of the present disclosure, the present disclosure provides a method for manufacturing the ring-shaped member 6112, which includes: s601, preparing a base material 6112B by using a flexible material, wherein the cross section of the base material 6112B is annular. The flexible material for preparing the base material 6112B may be rubber, fiber cloth, or the like, so that the ring 6112 can perform the effect similar to a conveyor belt. S602, the base material 6112B is tensioned by at least two tension rollers, and an adhesive is applied to the outer circumferential surface of the base material 6112B. In the present disclosure, at least one of the tension rollers may be driven to be rotatable so that the base substrate 6112B moves over the tension roller, thereby enabling convenient application of adhesive on the outer surface of the base substrate 6112B. S603, applying an adhesive on one surface of the cleaning body 6112A, placing the cleaning body 6112A on the base material 6112B, and taking down the base material 6112B from the tensioning roller after the adhesive is cured, so as to obtain the ring-shaped piece 6112.
One skilled in the art will appreciate that after the adhesive is applied to the outer surface of the tension roll, the adhesive may not be applied to the surface of the cleaning body 6112A. Alternatively, the adhesive may be applied only to the outer peripheral surface of the tension roller and one surface of the cleaning body 6112A. However, in order to provide the ring-shaped member 6112 with a better cleaning effect, the ring-shaped member 6112 of the present disclosure has an adhesive applied to both the outer circumferential surface of the tension roller and the surface of the ring-shaped member 6112 during the manufacturing process.
More preferably, in order to improve the service life of the ring 6112 and prevent the separation between the base material 6112B and the ring 6112 of the ring 6112, the circumferential direction of at least one end of the ring 6112 in the present disclosure is sewn by a sewing line 6112C, that is, at least one end of the cleaning body and at least one open end of the base material are fixed again, so that when the ring 6112 in the present disclosure is used, the currently conventional manner of pressing the end cap can be avoided, thereby reducing the cleaning-to-edge distance of the cleaning body 6112A. More preferably, both ends of the cleaning body 6112A are sewn by a sewing thread 6112C.
FIG. 42 shows a schematic view of an annular part prepared according to one embodiment of the present disclosure. FIG. 43 shows a schematic cross-sectional view of an annular member according to one embodiment of the present disclosure. FIG. 44 illustrates a schematic cross-sectional view of an annular member according to another embodiment of the present disclosure. As shown in fig. 42 and 43, in order to prevent the thread ends of the sutures 6112C on both sides from causing the protrusion of the ring 6112 when the ring 6112 is mounted to the first rotating part 6111 or the second rotating part 6113, thereby increasing the risk that the flexible annular belt portion falls off from the first rotating part 6111 or the second rotating part 6113, in the present disclosure, grooves may be formed on the outer circumferential surfaces of the first rotating part 6111 and the second rotating part 6113 at positions opposite to the sutures 6112C to accommodate the thread ends of the sutures 6112C and the sutures 6112C through the grooves; accordingly, when the grooves are formed at the first rotating part 6111 and the second rotating part 6113, the grooves on the first rotating part 6111 and the second rotating part 6113 are annular mounting grooves.
Further, as shown in fig. 44, a groove may be formed in the inner peripheral surface of the base material 6112B so that the sewing thread 6112C is positioned in the groove; more preferably, when the groove is formed on the inner peripheral surface of the base material 6112B, the groove may be formed as an annular mounting groove, or may not be formed, for example, the groove formed on the base material 6112B is formed in the shape of a blind hole to accommodate the joint of the suture 6112C through the blind hole.

As shown in fig. 49, when the detachable endless belt cleaning assembly is mounted to the housing module 650, considering that the flexible endless belt portion is in a tensioned state, the first rotating portion 6111 and the second rotating portion 6113 may approach each other under the force applied by the flexible endless belt portion, resulting in the first rotating portion 6111 and the second rotating portion 6113 not being properly aligned with the first support bearing and the second support bearing, and the first rotating portion 6111 and the second rotating portion 6113 needing to maintain interference fits with the first support bearing and the second support bearing, respectively, which all cause difficulty in mounting, and the user experiences a poor experience when washing the replacement endless belt and when mounting and dismounting the entire cleaning endless belt assembly.
Fig. 50 shows a schematic view of a cage installation location according to one embodiment of the present disclosure. Fig. 51 shows a schematic view of a cage in a disengaged state according to one embodiment of the present disclosure. At this time, as shown in fig. 50 and 51, the detachable endless belt cleaning assembly further includes a holder 6114, and the holder 6114 is provided to the first rotating part 6111 and the second rotating part 6113, for limiting positions of the first rotating part 6111 and the second rotating part 6113, to prevent the first rotating part 6111 and the second rotating part 6113 from approaching each other.
Preferably, there is at least one retainer 6114, when there is one retainer 6114, the retainer 6114 is disposed at one end of the first rotating part 6111 and the second rotating part 6113 far from the bracket part 618; when the number of the holders 6114 is set to two, the holders 6114 may be provided at both ends of the first rotating portion 6111 and the second rotating portion 6113. That is, in the present disclosure, the flexible annular belt portion can be made into a consumable, and the holder 6114 is installed on the other side of the bracket portion 618, so that the first rotating portion 6111 and the second rotating portion 6113 are prevented from approaching each other due to the tensioning action of the flexible annular belt portion, and the whole detachable annular belt cleaning assembly can be easily installed on the surface cleaning apparatus.
The cost of consumable materials made of the whole detachable annular belt cleaning assembly is too high, so that the flexible annular belt portion and the retainer 6114 can be considered as consumable materials, and the retainer 6114 is respectively installed on two sides of the cleaning annular belt, so that the assembly and replacement of a user are more convenient and the cost is lower.
Fig. 52 shows a schematic view of a ring 6112 according to one embodiment of the present disclosure. As shown in fig. 52, the circumferential length of the outer circumferential surface of the ring-shaped member 6112 of the present disclosure is 20cm or more, whereby the problem of hair entanglement in most use environments can be effectively solved. That is, since most of the fallen hairs in the home environment have a length of 20cm or less, when the circumference of the outer circumferential surface of the ring 6112 is set to 20cm or more, the hairs cannot be wound around the ring 6112 for one turn, and thus, when the ring 6112 is moved, the dirty things such as hairs are scraped off by the scraper and enter the dirty water storage portion via the dirty suction module 630.
Fig. 53 shows a schematic view of a cleaning base 600 in cleaning a surface to be cleaned according to one embodiment of the present disclosure. As shown in fig. 53, when the cleaning base 600 is used to clean a surface to be cleaned, the speed for pushing the surface cleaning apparatus to advance on the surface to be cleaned is about 0.5m/s, and if the linear velocity of the ring 6112 is less than 0.5m/s, a certain relative speed with the surface to be cleaned may not be formed, so that the cleaning base 600 cannot clean the same position at least once during the process of pushing and pulling the surface cleaning apparatus.
However, when the linear velocity of the surface of the flexible endless belt portion which is in contact with the surface to be cleaned is 0.5m/s or more (the direction of the linear velocity is backward), it can be ensured that the surface cleaning apparatus cleans a predetermined area of the surface to be cleaned at least once during use.
Fig. 54 shows a schematic structural view of a cleaning base 600 according to another embodiment of the present disclosure. Fig. 55 shows a schematic view of another angle of a cleaning base 600 according to another embodiment of the present disclosure. Fig. 56 shows an internal structural view of a cleaning base 600 according to another embodiment of the present disclosure. The moving wheel module 660 is disposed at the housing module 650 such that the lowest point of the moving wheel module 660 is located below the lowest point of the housing module 650, such that when the surface cleaning apparatus is in operation, the moving wheel module 660 contacts and rolls on the surface to be cleaned, thereby reducing the power required by the surface cleaning apparatus when moving; the moving wheel module 660 is located at the rear side of the housing module 650 to be able to effectively prevent the cleaning base 600 from contaminating the surface after cleaning has been performed.
In one aspect, as shown in fig. 27-29, the moving wheel module 660 is integrally formed with the housing module 650, i.e., the moving wheel module 660 includes: moving wheel frames 661 and moving wheels 662; wherein, the movable wheel frame 661 is integrally formed with the housing module 650 and is located at the rear side of the housing module 650; the moving wheel 662 is rotatably provided on the moving wheel frame 661. In the present disclosure, the moving wheel frame 661 includes two mounting members 6611, and the number of the moving wheels 662 is two, that is, one moving wheel 662 is mounted on each mounting member 6611, wherein the two mounting members 6611 are located between the two moving wheels 662, or in other words, the two moving wheels 662 are located outside the two mounting members 6611. Of course, those skilled in the art will appreciate that the moving wheels 662 may also be disposed inboard of the mounts 6611.
On the other hand, as shown in fig. 54 to 56, the moving wheel module 660 includes a moving wheel frame 661 and a moving wheel 662. Wherein the moving wheel frame 661 is formed separately from the housing module 650, and the housing module 650 is connected to the moving wheel frame 661 such that the housing module 650 can move with respect to the moving wheel frame 661. For example, the housing module 650 has at least one degree of rotational freedom with respect to the moving wheel frame 661, and preferably, the housing module 650 has two degrees of rotational freedom with respect to the moving wheel frame 661, i.e., a pitch degree of freedom (Y-axis) and a roll degree of freedom (X-axis).
The moving wheel frame 661 will be described in detail with reference to the accompanying drawings. As shown in fig. 55, the moving wheel frame 661 includes two mounting members 6611 and a connecting member 6612 connecting the two mounting members 6611.
Wherein the number of moving wheels 662 is two, i.e. one moving wheel 662 is mounted on each mounting 6611, wherein two mounting members 6611 are located between two moving wheels 662 or, in other words, two moving wheels 662 are located outside two mounting members 6611. Of course, those skilled in the art will appreciate that the moving wheels 662 may also be disposed inboard of the mounts 6611.
The housing module 650 is formed with a connection neck 652, and in the present disclosure, an axis of the connection neck 652 is disposed in a front-rear direction, and a rotation ring 663 is disposed outside the connection neck 652, and the connection neck 652 is allowed to rotate within the rotation ring 663, so that the housing module 650 has a tumbling degree of freedom. Also, the rotating ring 663 is rotatably provided to the connecting portion 6612, wherein the axis of rotation of the rotating ring 663 with respect to the connecting portion 6612 is parallel to the axis of rotation of the moving wheel 662 and is not collinear, so that the housing module 650 has a degree of freedom in pitch.
When the cleaning base 600 is used, since the cleaning area of the flexible annular band portion is large, if the unevenness of the floor at home is encountered, one surface is determined by three points, which inevitably results in the moving wheel 662 or the flexible annular band portion not being able to contact the floor at the same time, and if only one end of the flexible annular band portion is contacted with the floor, the other end inevitably is not able to contact the floor well, which results in an unsatisfactory cleaning effect.
However, the housing module 650 and the moving wheel module 660 of the present disclosure are connected in a hinged manner, so that relative floating is formed between the housing module 650 and the moving wheel module 660, thereby adapting to uneven ground, ensuring effective contact of the flexible annular belt portion with the surface to be cleaned, and ensuring cleaning effect.
As shown in fig. 27-29, the cleaning base 600 is mounted to a connection portion of the surface cleaning apparatus, e.g., detachably mounted to a main body portion of the surface cleaning apparatus, by a mounting adapter module 640 to enable at least a portion of the cleaning base 600 to contact a surface to be cleaned when the surface cleaning apparatus is operated and to enable cleaning of the surface to be cleaned when the cleaning base 600 is moved along a preset path.
The mounting adapter module 640 is rotatably disposed to the housing module 650 to enable a predetermined angle to be formed between the surface cleaning apparatus and the cleaning base 600, for example: when the surface cleaning apparatus is in the inoperative condition, the surface cleaning apparatus is at an angle of approximately 90 ° to the housing module 650 of the cleaning base 600, with the surface cleaning apparatus in an upright condition; when the surface cleaning apparatus is in an operational state, the angle between the surface cleaning apparatus and the housing module 650 of the cleaning base 600 is 120 ° or more, even the angle between the surface cleaning apparatus and the housing module 650 may be 180 °, i.e. both the surface cleaning apparatus and the housing module 650 are parallel to the surface to be cleaned, so that the surface cleaning apparatus of the present disclosure can clean the surface to be cleaned under a sofa as well as the surface to be cleaned under a bed, etc.
Fig. 57 and 59 show exploded schematic views of a cleaning base 600 according to one embodiment of the present disclosure. Fig. 58 shows a schematic view of another angle of a cleaning base 600 according to an embodiment of the present disclosure. Fig. 60 shows a schematic view of another angle of a cleaning base 600 according to an embodiment of the present disclosure. As shown in fig. 57-60, the fluid distribution module 620 of the cleaning base 600 of the present disclosure is disposed at a housing module 650 for providing cleaning liquid to the cleaning module 610, for example, to an endless belt cleaning device to enable wet cleaning of a surface to be cleaned by the endless belt cleaning device.
The fluid distribution module 620 comprises a flow control part 621 and a fluid distributor 622, wherein the flow control part 621 is connected to the cleaning liquid storage part of the surface cleaning apparatus through a first liquid supply pipeline, and is used for supplying the cleaning liquid stored in the cleaning liquid storage part of the surface cleaning apparatus to the fluid distributor 622 through the flow control part 621.
The flow control part 621 is connected to the fluid distributor 622 through the second liquid supply line to uniformly supply the cleaning liquid to the surface of the endless belt type cleaning device and maintain the endless belt type cleaning device in a wet state to be applied to the surface to be cleaned by the endless belt type cleaning device, thereby improving the cleaning quality.
When the flow control portion 621 is directly connected to the fluid distributor 622, the second fluid supply line may not be used; when a heating device is provided between the flow rate control portion 621 and the fluid distributor 622, the flow rate control portion 621 and the fluid distributor 622 are connected using a second liquid supply line, and at this time, the heating device is provided on the second liquid supply line.
In the present disclosure, the flow control portion 621 may be selected to be a water pump, preferably a peristaltic pump, so as to better prevent the liquid from leaking through the peristaltic pump and more precisely control the flow provided to the fluid dispenser 622, and a check valve or the like is not required.
Wherein the flow control portion 621 is disposed at the housing module 650 and may be located inside the housing module 650, and the fluid distributor 622 is also disposed at the housing module 650 and is located at the rear side of the cleaning module 610, for example, an endless belt type cleaning device.
In the present disclosure, the fluid distributor 622 is a labyrinth fluid distributor 622 so that the cleaning liquid is uniformly distributed on the surface of the endless belt type cleaning apparatus. The cleaning base 600 further comprises an upper housing 670, the upper housing 670 being provided to the housing module 650 and forming a part of the outer surface of the cleaning base 600 and at least partially covering the cleaning assembly; for example, the upper housing 670 is removably disposed to the housing module 650, and preferably, a rear portion of the upper housing 670 is removably disposed to the housing module 650, and a front portion of the upper housing 670 is positioned above the ring 6112 and at least partially covers the ring 6112.
As shown in fig. 64, the fluid dispenser 622 may include one or more water outlets, which may be formed in the housing module 650 or in the upper housing 670. In one implementation, the plurality of water outlets form a single row of formations.
The cleaning liquid flowing out to the surface of the ring member 6112 through the water outlet is uniformly distributed on the surface of the ring member 6112 after passing through the brush plate portion 671.
Wherein the wiper portion 671 is disposed on the upper housing 670 or is integrally formed with the upper housing 670, in one implementation, the wiper portion 671 extends along a length direction of the cleaning module, and both ends of the wiper portion 671 are not shorter than both ends of the ring member.
More preferably, the wiper portion 671 is located at a downstream side of the fluid distributor 622 in a moving direction of the ring-shaped member of the cleaning module, so that when the fluid distributor 622 supplies the cleaning liquid to the ring-shaped member of the cleaning module, the cleaning liquid is more uniformly distributed on the surface of the ring-shaped member 6112 by the wiper portion 671, and at this time, the wiper portion 671 is in contact with the surface of the ring-shaped member.
The fluid distributor 622 may be mounted to the upper housing 670 or the fluid distributor 622 may be integrally formed with the upper housing 670 to provide cleaning liquid to the outer surface of the rear portion of the ring 6112 and apply the cleaning liquid to the surface to be cleaned as the ring 6112 moves.
The fluid distributor 622 and the surface of the endless belt type cleaning device have a preset interval therebetween, wherein the size of the preset interval may be different according to the pressure of the cleaning liquid outputted from the flow control portion 621, for example, when the pressure of the cleaning liquid outputted from the flow control portion 621 is large, the preset interval is also large, and accordingly, when the pressure of the cleaning liquid outputted from the flow control portion 621 is small, the preset interval is also small. When the cleaning module 610 is an endless belt type cleaning device, if foreign matter enters the inner surface of the flexible endless belt portion, the foreign matter may enter between the flexible endless belt portion and the first rotating portion 6111 or the area between the flexible endless belt portion and the second rotating portion 6113, possibly causing damage to the endless belt.
For this reason, as shown in fig. 57 and 58, when the flexible annular band portion is attached around the first rotating portion 6111 and the second rotating portion 6113, the upper edge of the mounting portion 651 is formed not lower than the lower surface of the upper portion of one end of the flexible annular band portion, and the lower edge of the mounting portion 651 is formed not higher than the upper surface of the lower portion of one end of the flexible annular band portion, so that the mounting portion 651 can close one end of the flexible annular band portion.
Accordingly, the upper edge of the leg portion 618 is formed not lower than the lower surface of the upper portion of the other end of the flexible annular band portion, and the lower edge of the leg portion 618 is formed not higher than the upper surface of the lower portion of the other end of the flexible annular band portion, so that the leg portion 618 can close the other end of the flexible annular band portion.
Thus, by providing the mounting portion 651 and the bracket portion 618, foreign matter can be effectively prevented from entering the interior of the flexible annular band portion.
More preferably, in some implementations, an upper edge of the mounting portion 651 may be located below a lower surface of an upper portion of one end of the flexible annular band portion, and the one end of the flexible annular band portion is closed by the mating of the mounting portion 651 with a lower edge of the upper housing 670.
Accordingly, the upper edge of the leg portion 618 may also be located below the lower surface of the upper portion of the other end of the flexible annular band portion, and the other end of the flexible annular band portion may be closed by the engagement of the leg portion 618 with the lower edge of the upper housing 670.

The soil suction module 630 includes a suction port portion 631, the suction port portion 631 is located at the rear of the cleaning module 610, and the suction port portion 631 may be integrally formed with the housing module 650, in other words, the housing module 650 forms the suction port portion 631. The dirt suction module 630 further comprises a scraper portion 632, the scraper portion 632 being in contact with the flexible annular belt portion so that the scraper portion 632 can scrape dirt on the flexible annular belt portion off the flexible annular belt portion and further so that the dirt enters the suction port portion 631.
The scraper portion 632 may be fixed to the housing module 650, disposed adjacent to the suction port portion 631, and above the suction port portion 631.
In the present disclosure, the lower surface of the housing module is further provided with support wheels 680, and in the present disclosure, the number of the support wheels 680 may be two, and both the support wheels 680 are located at the rear of the soil suction module, so that the support wheels 680 rotate when the cleaning base moves forward or backward.
