Taking a floor washing robot as an example, the floor washing robot existing in the market at present generally comprises an air suction device, a sewage tank and a cleaning component (such as a cleaning roller brush, a brush and the like), a channel is arranged between the cleaning component and the sewage tank, one end of the channel is located at the cleaning component, the other end of the channel is communicated with a space in the sewage tank, meanwhile, the air suction end of the air suction device is communicated with the space in the sewage tank, when the air suction device works, the air suction device can draw out air in the sewage tank, and a negative pressure area is generated in the sewage tank, so that garbage (such as dust, sewage and the like) in the cleaning component is sucked into the sewage tank. And after the sewage tank is full of garbage, the user cleans the garbage in the sewage tank.

However, most of the existing sewage tanks of the floor washing robot are detachably connected to the machine body, when a user cleans garbage in the sewage tank, the user needs to detach the sewage tank from the machine body and then clean the garbage in the sewage tank, and after the cleaning is completed, the user needs to reinstall the sewage tank on the machine body. Obviously, current floor cleaning robot not only complex operation, the clearance is inconvenient to frequent dismouting also can harm the structure of junction, causes fatigue damage, influences the whole life of product.

In addition, the floor cleaning robot can continuously work only by relying on the user to regularly clean the sewage tank, and cannot realize full-automatic work, so that the use burden of the user is increased, and the user experience is influenced.

Therefore, how to realize the quick cleaning of the garbage in the sewage tank so as to reduce the burden of the user and improve the user experience becomes a problem to be solved in the field.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only some embodiments of the present application, and not all embodiments of the present application. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

Please refer to fig. 1 to fig. 10 and fig. 13. In the present embodiment, the cleaning apparatus a, includes at least a first water tank 1; the first water tank 1 is provided with a hollow cavity, a first accommodating space 11 is arranged in the cavity, a decontamination opening 12 is formed in the first water tank 1, the first accommodating space 11 is used for storing garbage recycled by the cleaning equipment A, and the decontamination opening 12 is communicated with the first accommodating space 11; the decontamination opening 12 has a docking mechanism 2, the docking mechanism 2 being adapted to engage with the external accessory 3 for use. When the external accessory 3 is docked with the docking mechanism 2, the docking mechanism 2 can guide and position the external accessory 3, so that the external accessory 3 can extract the garbage in the first accommodating space 11 through the decontamination opening 12. This means that the user can remove the garbage in the first receiving space 11 without taking down the first water tank 1 when removing the garbage using the external attachment 3. It should be noted that the waste described herein may be dry waste (e.g., dust, hair, etc.) or wet waste (e.g., sewage, fruit juice, etc.).

In an implementation, the cleaning device a may be provided with a base station 8, when the cleaning device a is docked with the base station 8, the base station 8 may perform operations such as charging, injecting fresh water, extracting sewage, etc. on the cleaning device a, and the external accessory 3 may be present in the base station 8 as part of the base station 8 and the external accessory 3 is driven by the base station 8 to dock with the docking mechanism 2. In another realizable embodiment, the external accessory 3 may exist as a separate component and the external accessory 3 is manually docked with the docking mechanism 2 by the user. This is not limited by the present application.

In practical application, the first water tank 1 can be used as a sewage tank for storing the above dry and wet garbage, and an air suction device 13 and a dust inlet 14 are arranged in the first water tank 1, an air suction end of the air suction device 13 is communicated with the first accommodating space 11, and the first accommodating space 11 is communicated with an external airflow channel through the dust inlet 14, so that when the air suction device 13 works, the air suction device 13 can suck the garbage swept by the cleaning equipment a from the dust inlet 14 into the first accommodating space 11 for storage, and further the garbage recycling action is realized. It should be noted that, in the above garbage collection operation, the air flow direction inside the first water tank 1 can refer to the arrow direction in fig. 1.

When the cleaning device a completes the above garbage recycling operation, or the garbage stored in the first accommodating space 11 reaches the upper limit value, the cleaning device a may remove the garbage in the first accommodating space 11. In practical applications, the user may manually dock the external accessory 3 with the docking mechanism 2, or the user sets the external accessory 3 on the base station 8 by means of the base station 8, and the docking of the external accessory 3 with the docking mechanism 2 is automatically controlled by the base station 8. When the external accessory 3 is docked with the docking mechanism 2, one end of the external accessory 3 can penetrate through the waste outlet 12 to enter the first accommodating space 11 and be inserted into the waste stored in the first accommodating space 11. The other end of the external accessory 3 is connected to a negative pressure device (not shown) which, when activated, allows the external accessory 3 to suck the waste.

In this embodiment, the air suction device 13 may use a single blower to rotate the fan to discharge the air in the first accommodating space 11 to the outside air, so as to generate a negative pressure in the first accommodating space 11. The external accessory 3 has at least an aspiration tube and a negative pressure pump, and the aspiration tube is communicated with the negative pressure pump, when the negative pressure pump works, the negative pressure pump can discharge the air in the aspiration tube to the outside air, so that the aspiration tube generates negative pressure, and thus, the external accessory 3 can suck the garbage stored in the first accommodating space 11 through the aspiration tube. It should be pointed out especially that, the suction pipe can adopt straight pipe fitting or hose, when the absorption end of suction pipe adopts the flat mouthful design, when the suction pipe inserts to first accommodation space 11 in, the absorption end of suction pipe should have certain interval with the bottom surface of first accommodation space 11 to make things convenient for above-mentioned suction pipe to absorb rubbish from this interval department. It should be noted that the drain port 12 may be provided on any side or top surface of the first tank 11, and the drain port 12 of the present application is preferably provided on the top surface of the first tank 1 in order to facilitate insertion of the external accessory 3 and subsequent installation of the docking structure 2.

In practical applications, the first water tank 1 and the decontamination opening 12 may be formed by an injection molding process or a 3D printing process, or the first water tank 1 may be formed and then the wall of the first water tank 1 is perforated to form the decontamination opening 12. In one embodiment, in order to reduce the occupied space of the cleaning device a, the bottom surface of the first water tank 1 may be provided with a first inner groove 15 and a second inner groove 16, wherein the first inner groove 15 is used for installing the suction device 13, so that the suction device 13 is embedded in the first water tank 1, the dust inlet 14 is arranged in the second inner groove 16, and the second inner groove 16 can be used for installing the cleaning component 72, thereby reducing the whole volume of the cleaning device a and making the structure of the cleaning device a more compact.

In an implementation, referring specifically to fig. 1 and 2, the docking mechanism 2 includes an annular soft glue 21, wherein the annular soft glue 21 is disposed in the decontamination opening 12; the annular soft rubber 21 is provided with a middle hole position 211, the top end of the middle hole position 211 is provided with a chamfer 212, the middle hole position 211 penetrates through the upper end and the lower end of the annular soft rubber 21, and when the annular soft rubber is used, the middle hole position 211 is used for yielding the external accessory 3. When the external accessory 3 is butted with the butting mechanism 2 through the annular soft rubber 21, the chamfer 212 can guide and position the external accessory 3, so that the external accessory 3 can be accurately inserted into the middle hole position 211. That is to say, the chamfer 212 disposed at the top end of the middle hole 211 can increase the opening area at the top end of the middle hole 211, so that when the external accessory 3 is butted with the butting mechanism 2, even if there is a certain error in the relative position of the external accessory 3 and the butting mechanism 2, the external accessory 3 can be inserted into the butting mechanism 2, thereby facilitating the matching use of the external accessory 3 and the butting mechanism 2. It should be pointed out that annular flexible glue 21 can with 3 interference fit of external parts to when making when external parts 3 takes out from annular flexible glue 21, the inner wall of annular flexible glue 21 strikes off the rubbish of adhesion on the outer wall of external parts 3, thereby avoids rubbish along with external parts 3 removes, drips in the cleaning device A outside, causes environmental pollution.

It should be particularly noted that, since the middle hole portion 211 communicates the first accommodating space 11 with the outside air, when the air suction device 13 works, the middle hole portion 211 may affect the negative pressure generated by the air suction device 13 in the first accommodating space 11 to a certain extent, but in practical applications, since the diameter of the middle hole portion 211 is not large, when the suction force of the air suction device 13 is large enough, the negative pressure generated by the air suction device 13 in the first accommodating space 11 may achieve the effect of sucking the garbage from the dust inlet 14 into the first accommodating space 11, and the middle hole portion 211 may not affect the normal operation of the cleaning apparatus a.

In practical application, annular flexible glue 21 can adopt the rubber material to annular flexible glue 21's structure can adopt the ring column, and is corresponding, decontaminates mouthful 12 and adopts the round hole design, and annular flexible glue 21 can adopt the mode of bonding to connect in decontaminating mouthful 12 after the location. In addition, in order to facilitate the installation of the annular soft rubber 21, the structure of the annular soft rubber 21 can also adopt a stepped column shape, correspondingly, the decontamination opening 12 adopts a stepped hole, when in use, the annular soft rubber 21 only needs to be matched with and placed on the decontamination opening 12, and the positioning is not needed.

In order to further improve the suction effect of the suction device 13 on the garbage, the decontamination opening 12 can be sealed, which is shown in fig. 3, in order to solve the problem that the communication between the first accommodating space 11 and the outside air through the middle hole 211 may affect the negative pressure generated by the suction device 13 in the first accommodating space 11 to a certain extent. In an achievable embodiment, a first cover plate 41 and a torsion spring 42 are arranged on the inner wall of the first accommodating space 11, wherein one end of the first cover plate 41 is hinged on the inner wall of the first accommodating space 11, the first cover plate 41 is located below the decontamination opening 12, and the torsion spring 42 is connected between the first cover plate 41 and the inner wall of the first accommodating space 11. When the external accessory 3 is not inserted into the decontamination opening 12, the torsion spring 42 can drive the first cover plate 41 to cover the decontamination opening 12, so as to seal the decontamination opening 12, thereby ensuring the suction effect of the suction device 13. That is, when the cleaning apparatus a performs a cleaning operation, the torsion spring 12 always controls the first cover plate 41 to seal the dirt removing opening 12, so as to prevent outside air from entering the first accommodating space 11 through the dirt removing opening 12. When the garbage stored in the first accommodating space 11 needs to be removed, the external accessory 3 needs to be docked with the docking mechanism 2, and at this time, in the process of extending the external accessory 3 downward, the elastic force generated by the torsion spring 42 is overcome, so that the first cover plate 14 is opened, and thus, the external accessory 3 can be inserted into the first accommodating space 11. Note that, when the first cover plate 41 covers the decontamination opening 12, the first cover plate 41 may completely cover the decontamination opening 12, thereby forming a complete seal for the decontamination opening 12; the specific structure of the torsion spring 42 can be implemented by the prior art, and the detailed description thereof is omitted here.

In practice, since the external accessory 3 is inserted directly into the waste when it is sucked, the external wall of the external accessory 3 adheres to some of the waste during the suction. After the sucking work is finished, the external accessory 3 is withdrawn from the decontamination opening 12, and in the process, the garbage adhered on the outer wall of the external accessory 3 is continuously accumulated at the annular soft rubber 21. The garbage accumulated at the annular soft rubber 21 can corrode the annular soft rubber 21 and affect the sealing effect between the annular soft rubber 21 and the first cover plate 41. In order to solve the above problem, with particular reference to fig. 4 and 10, in an implementable embodiment, the docking mechanism 2 further comprises a base 22, wherein the base 22 is provided with a cavity 221, a docking member 222 and an extension duct 223; the extension pipe 223 is butted and communicated with the external attachment 3 through the butting piece 222. Specifically, the extension pipe 223 may be disposed at the bottom of the base 22, one end of the extension pipe 223 is communicated with the cavity 221 through the butt joint piece 222, and the other end of the extension pipe 223 is communicated with the first accommodating space 11, that is, the other end of the extension pipe 223 is located inside the first accommodating space 11; the cavity 221 communicates with the decontamination port 12 so that when the external attachment 3 enters the cavity 221 through the decontamination port 12, the external attachment 3 can communicate with the extension pipe 223 through the docking piece 222. In other words, when the garbage in the first accommodating space 11 needs to be cleaned, the external accessory 3 can penetrate through the garbage inlet 12 and extend into the cavity 221, and is communicated with the extension pipeline 223 through the butt joint piece 222, so that the external accessory 3 does not need to extend into the garbage, and can absorb the garbage through the extension pipeline 223, and therefore when the external accessory 3 absorbs the garbage, the garbage does not adhere to the outer wall of the external accessory 3.

It should be noted that the docking mechanism 2 in this embodiment may be used alone in the first water tank 1, or may be used in combination with the first cover plate 41 and the torsion spring 42. When the docking mechanism 2 in the present embodiment is used in combination with the first cover plate 41 and the torsion spring 42, the installation positions of the first cover plate 41 and the torsion spring 42 need to be adjusted correspondingly, specifically, one end of the first cover plate 41 is hinged to the inner wall of the base 22, and the first cover plate 41 is located below the decontamination opening 12; a torsion spring 42 is connected between the first cover 41 and the inner wall of the base 22 to drive the first cover 41 to open or close the soil-removing opening 12. In other words, during the process that the external accessory 3 extends into the decontamination opening 12, since the downward pressure of the external accessory 3 is greater than the elastic force of the torsion spring 42, the first cover plate 41 is forced to be turned downward, thereby opening the decontamination opening 12; during the process of extracting the external attachment 3 from the stain removal port 12, the first cover plate 41 is turned upward by the torsion spring 42 due to the gradual decrease of the downward pressure of the external attachment 3, thereby closing the stain removal port 12.

In the present embodiment, in consideration of the situation that the garbage in the first accommodating space 11 may overflow the butt joint between the external accessory 3 and the butt joint piece 222, and thus the garbage may still adhere to the outer wall of the external accessory 3, the present application makes a corresponding arrangement, wherein the butt joint piece 222 has a first height in the first water tank 1, the first accommodating space 11 may be provided with the sewage upper limit 17, and the sewage upper limit 17 is ensured to be smaller than the first height; in other words, the upper limit 17 of the waste water is located below the abutment member 222 so as to prevent the waste from contacting the external attachment 3, thereby preventing the waste from adhering to the outer wall of the external attachment 3. It should be noted that the first height is a height from the abutting piece 222 to the bottom surface of the first accommodating space 11; the above-mentioned sewage upper limit 17 specifically means the highest position in the first accommodation space 11, where garbage can be accommodated. In practical application, limit 17 department can be provided with laser sensor on the sewage in first accommodation space 11, and laser sensor is used for judging whether rubbish exceedes sewage upper limit 17, and when rubbish exceeded sewage upper limit 17, laser sensor can detect the signal to transmission signal to control end stops clean action by control end control cleaning device A, thereby avoids the rubbish height in first accommodation space 11 to exceed sewage upper limit 17.

Preferably, the drain port 12 is located at the top of the first tank 1, the base 22 is connected below the drain port 12, and the extension pipe 223 is disposed below the base 22. Specifically, the central axis of decontamination opening 12 and the central axis of epitaxial pipeline 223 are on same straight line, and this straight line passes through cavity 221, thereby make when external annex 3 need with the butt joint piece 222 butt joint, external annex 3 can direct vertical insertion to decontamination opening 12 in, can dock with butt joint piece 222, the operation is simple and convenient more, and external annex 3 and epitaxial pipeline 223 are on same straight line, rubbish in the first accommodation space 11 can be by the vertical extraction of external annex 3, realize the rubbish extraction of shortest distance, improve extraction efficiency, and do not have the region of buckling between external annex 3 and the epitaxial pipeline 223, reduce the possibility that the jam appears.

In practical applications, the base 22 and the extension pipe 223 can be made as a whole by an integral molding process. Of course, the base 22 and the extension pipeline 223 may also adopt a split structure, for example, a threaded hole is provided at the bottom of the base 22, correspondingly, an external thread is provided at the top end of the extension pipeline 223, and the extension pipeline 223 is connected with the base 22 through a thread; in addition, in long-term use, torsional spring 42 and butt joint piece 222 easily take place fatigue damage, and the inside laying dust condition that also can produce of base 22, for the convenience of the maintenance change in later stage, first apron 41 and torsional spring 42 can be incorporated into to docking structure 2, and as a whole, docking structure 2 adopts the mode of pegging graft to connect on first water tank 1.

In consideration of the above, when the torsion spring 42 is used to drive the first cover plate 41 to seal the decontamination opening 12, the elasticity of the torsion spring 42 against the first cover plate 41 is too large during the opening of the first cover plate 41, which makes it difficult for the external accessory 3 to push the first cover plate 41 open.

In view of the above problem, in an implementation mode, please refer to fig. 5, 6 and 10 together, the present application further provides another structure for sealing the decontamination opening 12, i.e. the docking mechanism 2 further includes a tension spring 23, a turnover rod 24 and a second cover plate 25. The middle part of the turning rod 24 is hinged on the inner wall of the base 22, one end of the turning rod 24 is connected with the second cover plate 25, the second cover plate 25 is positioned below the decontamination opening 12, the turning rod 24 can turn around the middle part to drive the second cover plate 25 to turn, and when the second cover plate 25 turns over to the upper part, the second cover plate 25 is used for sealing the decontamination opening 12; the other end of the turning rod 24 is connected with the base 22 through a tension spring 23, wherein the tension spring 23 is positioned below the turning rod 24; because the tension spring 23 always provides a downward tension to one end of the turnover rod 24, the other end of the turnover rod 24 always has an upward turnover force, and the force enables the second cover plate 23 to always seal the cleaning opening 12 under the condition of not receiving external force.

In other words, during the process that the external accessory 3 enters the decontamination opening 12, the external accessory 3 will exert a downward pressure on the second cover plate 25, and when the pressure is greater than the upward force provided by the tension spring 23 on the second cover plate 25, the second cover plate 25 opens, so that the external accessory 3 enters the base 22; when the downward pressure on the second cover plate 25 disappears after the external accessory 3 is detached from the base 22, the second cover plate 25 is driven by the turnover rod 24 to turn over upwards until the second cover plate turns over to be attached to the bottom end of the decontamination opening 12, so that the decontamination opening 12 is sealed.

In the practical use process of the two structures for sealing the decontamination opening 12, on one hand, a part of gas enters the base 22 during the opening process of the first cover plate 41 or the second cover plate 25, and on the other hand, because 100% of gas does not leak during the practical sealing process of the decontamination opening 12 by the first cover plate 41 or the second cover plate 25, when the cleaning device a performs a cleaning operation, the suction device 13 generates a negative pressure in the first accommodating space 11, at this time, as shown in the arrow direction in fig. 5, the gas existing in the cavity 221 and/or the gas leakage generated at the sealing position of the cover plate (hereinafter, the first cover plate 41 or the second cover plate 25 is referred to as the cover plate for avoiding ambiguity) and the decontamination opening 12 enter the bottom sewage through the extension pipe 223 to generate bubbles, and the bubbles float to the water surface and then burst, so that moisture exists in the air in the first accommodating space 11, these moisture enter the air intake device 13 along with the intake air generated by the air intake device 13, and corrode the air intake device 13, which affects the service life of the air intake device 13.

In view of the above problem of air bubbles, the present application further improves the base 22, and in an implementation manner, please refer to fig. 6, 9 and 10, an air hole 224 is formed on a side wall of the base 22, and the air hole 224 is used for communicating the cavity 221 with the first accommodating space 11, so that the air in the cavity 221 is discharged into the first accommodating space 11 through the air hole 224. Meanwhile, in order to prevent the garbage from entering the cavity 221 through the ventilation hole 224 and attaching to the external accessory 3, it is necessary to ensure that the ventilation hole 224 is positioned above the sewage upper limit 17. In other words, referring to the arrow direction in fig. 6, when the air suction device 13 generates negative pressure in the first accommodating space 11, the air leakage generated at the sealing position between the cover plate and the decontamination opening 12 and/or the air existing in the cavity 221 directly enters the first accommodating space 11 through the air holes 224, so that the air does not enter the sewage, and the generation of air bubbles is avoided.

In practical applications, the ventilation holes 224 may be formed integrally with the base 22, or the ventilation holes may be formed by forming the base 22 and then performing subsequent holes. In addition, the vents 224 may be located on any one or more sides of the base 22. It should be noted that, when the air holes 224 are disposed on the side surface corresponding to the cover plate turned over to the lower side, it should be ensured that the air holes 224 cannot be completely blocked by the first cover plate 41 or the second cover plate 25, so that the air can flow into the first accommodating space 11 from the remaining air holes 224, and the air is prevented from entering the sewage to generate bubbles.

In one implementation, referring to FIG. 13, the cleaning device A may also include a power module 5. The power supply assembly 5 is used for being connected with an external charging assembly 6 in a butt joint mode, so that the charging assembly 6 charges the cleaning device A, wherein the charging assembly 6 and the external accessory 3 can be integrated into a whole, and therefore the external accessory 3 extracts garbage while the cleaning device is charged; the power module 5 and the charging module 6 have a mating direction, and the opening direction of the cover is the same as the mating direction. Note that the docking direction refers to a direction in which the power supply unit 5 moves toward the charging unit 6 when the power supply unit 5 needs to be connected to the charging unit 6, specifically, see an arrow a in fig. 13; the opening direction of the cover panel refers to a horizontal direction toward which the cover panel is turned when the cover panel is turned by a downward pressure of the external attachment 3, specifically, see an arrow direction b in fig. 13.

In the present embodiment, referring to fig. 13, when the external attachment 3 contacts the cover plate, a force is generated in a lateral direction of the cleaning apparatus a, and the direction of the force is the opening direction of the cover plate. In order to avoid the power module 5 from being separated due to the force after contacting the charging module 6, and thus affecting the charging, it is necessary to ensure that the opening direction of the cover is the same as the docking direction, that is, the force direction is toward the docking direction, so that the power module 5 is always pushed by the force to contact the charging module 6 during the charging process.

In practical application, the power supply assembly 5 should at least include a storage battery part and a charging connector, and the charging connector should be located at one end of the cleaning device a so as to be in contact with the charging assembly 6; the charging assembly 6 can be a socket or a charging elastic sheet, and when the charging connector is inserted into the socket or is in contact with the charging elastic sheet, the storage battery part is charged.

In an implementation, referring to fig. 11, the cleaning device a also has a second water tank 71, a cleaning assembly 72 and an overflow assembly. The overflow assembly includes an overflow hole 73 and a guide pipe 74, wherein the overflow hole 73 is opened on the second water tank 71, one end of the guide pipe 74 is communicated with the overflow hole 73, and the other end of the guide pipe 74 is located at the cleaning assembly 72. In other words, when the cleaning device a shakes during movement or is filled with water, the liquid contained in the second water tank 71 reaches the position of the overflow hole 73, the liquid flows out of the overflow hole 73 and is guided to the cleaning part 721 of the cleaning assembly 72 through the guide pipe 74 (the flow direction of the overflow liquid can be specifically seen in the arrow direction in fig. 11), and the overflowed liquid is used for cleaning, so that waste is avoided, and the liquid can be prevented from flowing out of other positions to cause secondary pollution.

In practice, the second water tank 71 may be used for containing clean water in the cleaning device A, and the second water tank 71 is used for supplying liquid to the cleaning part 721 of the cleaning assembly 72 during the cleaning process, so as to facilitate the cleaning operation. The cleaning assembly 72 may include a cleaning portion 721 and a stiff glue line 722, wherein the cleaning portion 721 may be a roller or a disc brush; the ebonite pipeline 722 is parallel to the cleaning part 721 in the length direction, and the other end of the flow guide pipe 74 is used for being communicated with the ebonite pipeline 722, so that overflowing liquid is transmitted to the ebonite pipeline 722, and then the ebonite pipeline 722 uniformly distributes the liquid to the cleaning part 721, thereby preventing the overflowing liquid from flowing to a certain part of the cleaning part 721 only, and preventing water from being accumulated on the cleaning part 721 too much to affect the cleaning effect.

In this embodiment, the overflow hole 73 may be disposed at any position on the sidewall of the second water tank 71, but it is necessary to ensure that the overflow hole 73 is higher than the bottom of the second water tank 71 by a certain height, so as to ensure that the overflow hole 73 only overflows the excess liquid; the draft tube 74 may employ a hose so as to be conveniently connected between the cleaning portion 721 and the overflow hole 73.

In an implementation manner, referring to fig. 12, the second water tank 71 further has a water injection hole 75, and a liquid level sensor 76 is disposed on a side wall of the second water tank 71. The water injection hole 75 is used for docking with the external attachment 3 so that the external attachment 3 injects water into the second water tank 71 through the water injection hole 75; it should be noted that in the present application, the external accessory 3 not only has a garbage extraction module, but also has a water injection module, that is, the external accessory 3 can not only extract the garbage in the first water tank 1, but also inject water into the second water tank 71; the level sensor 76 is used for detecting the water level in the second water tank 71, so that the external accessory 3 controls the flow rate of water injection of the external accessory 3 based on the signal sent by the level sensor 76; it should be noted that the above-mentioned controlling the water injection flow rate of the external accessory 3 means to decrease the water injection speed or increase the water injection flow rate, and decreasing the water injection speed or increasing the water injection flow rate also includes adjusting the water injection flow rate to zero or adjusting the zero flow rate to a high flow rate, in other words, the external accessory 3 can turn on the water injection, turn off the water injection, and decrease/increase the water injection speed according to the signal of the liquid level sensor 76.

In practical applications, the position of the liquid level sensor 76 may be set at any one of the inner bottom surface of the second water tank 71, the inner middle level of the second water tank 71, the position flush with the overflow level of the overflow hole 73, and the position inside the overflow hole 73;

when the liquid level sensor 76 is disposed on the inner bottom surface of the second water tank 71, the water filling process is: when the level sensor 76 fails to detect liquid, the cleaning device a is moved to the external accessory 3 for filling; when water injection is started, the liquid level sensor 76 detects a signal and performs water injection according to a preset first water injection time and a preset second water injection time, when the first water injection time is reached, the external accessory 3 reduces the water injection speed to perform slow water injection, the water injection is finished when the second water injection time is reached, and the water injection is finished.

When the liquid level sensor 76 is disposed at the middle position inside the second water tank 71, the water filling flow is as follows: when the cleaning device a returns to the external accessory 3 after cleaning is completed and the liquid level sensor 76 cannot detect liquid, the external accessory 3 injects water into the second water tank 71 of the cleaning device a until the liquid level sensor 76 detects a signal, the external accessory 3 reduces the water injection speed and sets the water injection stopping time, water is slowly added, the water is added until the water injection stopping time is over, and the water injection is over.

When the liquid level sensor 76 is arranged at the level of the overflow hole 73, the water filling process is as follows: when the cleaning of the cleaning device a is completed, the water is filled back to the external attachment 3 until the water level sensor 76 detects a signal, and the water filling is finished.

When the liquid level sensor 76 is arranged in the overflow hole 73, the water injection flow is as follows: after cleaning of the cleaning device is completed, the cleaning device returns to the external attachment 3 for filling until the filling is completed when the filling level sensor 76 detects a signal.

It should be noted that, as can be seen from fig. 12, the U-shaped structure is formed by a horizontal rod and two vertical rods disposed at two ends of the horizontal rod, and the two vertical rods of the U-shaped structure of the present application are corresponding structures.

In practical application, the U-shaped structure can play a role in gently impacting injected liquid, when the external accessory 3 injects water into the water injection hole 75, due to the bent shape of the U-shaped structure, the liquid continuously collides to be gentle in the U-shaped structure in the process that the liquid flows from one end of the U-shaped structure to the other end, and thus large waves cannot be generated when the liquid reaches the other end; in other words, under the condition that the liquid level sensor 76 is arranged at the middle position, the position flush with the overflow position of the overflow hole 73 or in the overflow hole 73, the U-shaped structure can avoid water splash generated by water injection, and the condition of false detection on the liquid level sensor 76 can be avoided, so that the normal operation of the cleaning device A is ensured.

In addition, in order to reduce the volume of the cleaning device a as much as possible, the overflow assembly of the present application further includes a small column section 77, and the overflow hole 73 is located at the bottom of the second water tank 71; the small column section 77 is of a tubular structure, is positioned inside the second water tank 71 and protrudes out of the inner bottom surface of the second water tank 71; that is, the inside of the second water tank 71 is communicated with the overflow hole 73 through the small column section 77, so that the overflow hole 73 can be disposed at the bottom of the second water tank 71 under the condition that the overflow is satisfied, thereby connecting the draft tube 74 therebelow and reducing the occupation of the lateral space.

In practical application, under the condition of shaking generated in the moving process of the cleaning device a and during water injection, overflow liquid is generated, the generated overflow liquid enters the small column section 77 through the top end opening of the small column section 77 and flows onto the cleaning part 721 through the small column section 77, the overflow hole 73 and the guide pipe 74 in sequence; wherein, the pillar section 77 and the second water tank 71 can be integrally formed by injection molding.
