As shown in fig. 12 to 14, the dust collection device 400 includes a dust collection container 410, a suction device 420, a dust collection part 430, and a filter device 440.
The dust collecting container 410 is connected to the suction device 420, so that a negative pressure is generated in the dust collecting container 410 by the suction device 420, and thus the dirt generated by the rolling brush cleaning assembly 320 cleaning the surface to be cleaned is sucked into the dust collecting container 410.
The dust collection container 410 is connected to the dust collection part 430, wherein the dust collection part 430 partially wraps the drum brush cleaning assembly 320 such that the dirt generated from the cleaning of the surface to be cleaned by the drum brush cleaning assembly 320 enters the dust collection container 410 through the dust collection part 430.
The dust collection part 430 is formed with an opening, and a portion of the drum brush cleaning assembly 320, for example, a portion of the drum brush part 321 of the drum brush cleaning assembly 320, is located outside the dust collection part 430 through the opening, so that the drum brush part 321 of the drum brush cleaning assembly 320 is in contact with a surface to be cleaned when the automatic cleaning apparatus 10 is in operation.
A portion of the dust collection part 430 located behind the roller brush cleaning assembly 320 is formed in a planar shape and is disposed at an interval from one end of the protruding part 321 of the roller brush cleaning assembly 320, which is away from the drum part, to reduce resistance of the air flow inside the dust collection part 430 and allow dirt carried in the air flow to be transferred to the dust collection container 410.

In other words, the lower end of the portion of the dust collection part 430 located behind the roller brush cleaning assembly 320 is higher than the lowest position of the roller brush cleaning assembly 320, and when the roller brush cleaning assembly 320 is in contact with the surface to be cleaned, the lower end of the portion of the dust collection part 430 located behind the roller brush cleaning assembly 320 is spaced apart from the surface to be cleaned.
Fig. 14 is another perspective view of the dust collector after removing the suction device according to one embodiment of the present disclosure. Fig. 15 is a schematic structural view of a dust collecting container according to an embodiment of the present disclosure. Fig. 16 is another angular configuration schematic view of a dust collection container according to an embodiment of the present disclosure.
In the present disclosure, as shown in fig. 13 to 16, the dust collection container 410 includes a case portion 411, a cover plate portion 412, a cover member 413, and a baffle portion 414.
Wherein, the case portion 411 is formed with an accommodating space for storing solid wastes, and an inlet is formed on a sidewall of the case portion 411 to make the dust collection portion 430 communicate with an inner space of the case portion 411 by the provision of the inlet, and to make the soil conveyed through the dust collection portion 430 be stored in the accommodating space.
A cover portion 412 is provided to the case portion 411 to open or close an inlet of the case portion 411. Wherein the cover portion 412 may be disposed outside the box portion 411 or inside the box portion 411, and preferably, as shown in fig. 15, the cover portion 412 is disposed inside the box portion 411, and when negative pressure is generated inside the box portion 411 (for example, when the suction device 420 is operated), the cover portion 412 opens the inlet of the box portion 411; when negative pressure is not generated inside the case portion 411 (for example, the suction device 420 stops operating), the cover portion 412 closes the inlet of the case portion 411.
That is, when the air pressure inside the case portion 411 is less than the air pressure inside the dust collection portion 430, and the absolute value of the difference between the air pressure inside the case portion 411 and the air pressure inside the dust collection portion 430 is greater than or equal to a preset value, the cover portion 412 opens the inlet of the case portion, otherwise, the cover portion 412 closes the inlet of the case portion 411.
As one implementation form, as shown in fig. 13, the cover portion 412 is hinged to the case portion 411 so that the cover portion 412 is attached to the case portion 411 or spaced apart from the case portion 411 by a preset distance by rotation of the cover portion 412 around the hinge axis of the cover portion 412 and the case portion 411, and when the cover portion 412 is attached to the case portion 411, the cover portion 412 closes the entrance of the case portion 411, and when the cover portion 412 is spaced apart from the front of the case portion 411 by the preset distance, the cover portion 412 opens the entrance of the case portion 411.

As shown in fig. 13, a part of the case portion 411 is formed as a first part of the case portion 411, and another part of the case portion 411 is formed as a second part of the case portion 411, wherein the second part has a height smaller than that of the first part, and the discharge port is provided near a side wall of the first part.
Accordingly, the bottom wall of the first portion of the box portion 411 is the first bottom wall 4111 forming the box portion 411, and the bottom wall of the second portion of the box portion 411 is the second bottom wall 4112 forming the box portion 411, and for convenience, the technical terms first bottom wall 4111 and second bottom wall 4112 are used to describe the disclosure.
Accordingly, the suction device is disposed at the bottom wall of the second portion of the box portion 411, i.e., the suction device 420 can be placed below the second bottom wall 4112 of the box portion 411.
Of course, the suction device 420 may be provided at other positions of the box portion 411 as long as the suction device 420 communicates with the inner space of the box portion 411.
The upper end of the case portion 411 is open, and a cover member 413 is provided to the case portion 411 to open or close the upper end of the case portion 411; that is, the cover member 413 has a first position and a second position, and when the cover member 413 is located at the first position, the cover member 413 closes the opening of the upper end of the case portion 411, and when the cover member 413 is located at the second position, the opening of the upper end of the case portion 411 is opened.
In an alternative embodiment of the present disclosure, as shown in fig. 13, the upper end of the case portion 411 is formed with an annular groove formed in a circle along the upper end face of the case portion 411; the lower surface of the cover member 413 is formed with an annular boss shaped to fit the annular recess so that when the cover member 413 is in the first position, the annular boss is located within the annular recess, thereby forming a seal between the case portion 411 and the cover member 413.
Of course, the sealing between the box 411 and the cover 413 may be achieved by other structures, for example, a sealing gasket is provided between the box 411 and the cover 413; or the upper end surface of the case portion 411 is formed with an annular projection, the lower surface of the cover member 413 is formed with an annular groove, and this is achieved by fitting the annular projection of the case portion 411 and the annular groove of the cover member 413.

Preferably, a through hole is provided in the second bottom wall 4112 of the box portion 411, whereby the suction device 420 can be directly connected to the filter device 440 to reduce the connection line between the suction device 420 and the filter device 440.
The filtering device 440 is provided inside the dust collection container 410 to filter the gas flowing to the suction device 420 to prevent dust from entering the suction device 420 to damage the suction device 420.
That is, when the suction device 420 is operated, a negative pressure is generated in the dust collection container 410, and the dirt generated when the roller brush cleaning assembly 320 cleans the surface to be cleaned is mixed in the air and is sucked into the dust collection container 410 by the suction device 420.
After the contaminated gas enters the dust collection container 410, the filtered gas is discharged to the outside of the dust collection container 410 by the suction device 420 through the filtering action of the filter device 440, and at this time, the contaminated gas is deposited in the dust collection container 410.

According to at least one embodiment of the present disclosure, as shown in fig. 17 and 18, the shutter portion 414 is used to open or close the discharge port of the case portion 411, that is, when negative pressure is generated in the cleaning duct 450, the shutter portion 414 opens the discharge port of the case portion 411, and when the air pressure in the cleaning duct 450 is equal to or greater than the air pressure in the case portion 411, the shutter portion 414 closes the discharge port of the case portion 411.
That is, when the air pressure outside the shutter portion 414 (e.g., the air pressure inside the cleaning duct 450) is smaller than the air pressure inside the box portion 411, and the absolute value of the difference between the air pressure outside the shutter portion 414 (e.g., the air pressure inside the cleaning duct 450) and the air pressure inside the box portion 411 is equal to or greater than a preset value, the shutter portion 414 opens the discharge port; otherwise, the shutter portion 414 closes the discharge port; that is, when the air pressure outside the baffle portion 414 is equal to or greater than the air pressure inside the box portion 411, or the air pressure outside the baffle portion 414 is smaller than the air pressure inside the box portion 411, and the absolute value of the difference between the air pressure outside the baffle portion 414 and the air pressure inside the box portion 411 is smaller than a preset value, the baffle portion 414 closes the discharge port.
When the baffle portion 414 opens the discharge port, the gas entering the inside of the box portion 411 through the inlet of the box portion 411 flows through at least a part or all of the bottom surface of the accommodating space of the box portion 411 for storing the solid waste, and then flows out of the discharge port of the box portion 411, so that the solid waste stored in the accommodating space of the box portion 411 for storing the solid waste is conveyed to the outside of the box portion 411 with the airflow.
As one implementation form, the shutter portion 414 may be hinged to a side wall of the case portion 411 to open or close the discharge port of the case portion 411 by rotation of the shutter portion 414.

Preferably, the elastic restoring portion 415 may be a torsion spring to provide a torsion force to the barrier portion 414 through the torsion spring and to make the barrier portion 414 in a normally closed state.
Of course, the baffle portion 414 may be opened or closed by other structures, for example, by an electromagnetic lock, in which case, when the automatic cleaning apparatus is in an operating state, the electromagnetic lock attracts the baffle portion 414, so that the baffle portion 414 closes the outlet; when the solid waste in the automatic cleaning device needs to be discharged to the outside of the automatic cleaning device, the electromagnetic lock opens the baffle portion 414, and when negative pressure is supplied to the box portion 411 through the discharge port, the discharge of solid particles can be realized.
On the other hand, the power of the electromagnetic lock may be controlled by the pressure difference between the inside and the outside of the discharge port of the casing 411, for example, when the air pressure outside the discharge port is smaller than the air pressure inside the casing 411 and the absolute value of the pressure difference between the air pressure outside the discharge port and the air pressure inside the casing 411 is equal to or greater than a preset value, the electromagnetic lock is controlled to operate so that the baffle portion 414 opens the discharge port, otherwise, the electromagnetic lock is controlled so that the baffle portion 411 closes the discharge port.

The limiting portion of the side wall of the box portion 411 may be formed as a part of the side wall of the box portion 411, for example, the size of the side wall of the box portion 411 is smaller than that of the baffle portion 414; or, the first bottom wall 4111 is formed with a step, and the step forms a limiting portion.
Preferably, the sealing member 416 is an annular sealing member, so that the gas is effectively prevented from entering the interior of the dust collection container 410 through the discharge port by the arrangement of the sealing member 416, so as not to lower the negative pressure inside the case portion 411 when the automatic cleaning apparatus 10 is in an operating state.

For example, a shoulder is formed on the first output shaft 539A, and the stopper portion 547 is provided to the shoulder of the first output shaft 539A to limit the axial position of the stopper portion 547 at the first output shaft 539A by the shoulder of the first output shaft 539A and to space the stopper portion 547 a predetermined distance from the transmission body 531 of the speed changing device 530.
That is, one end of the elastic restoring portion 545 abuts on the stopper portion 547, so that when the first output shaft 539A rotates, the stopper portion 547 is rotated, and thus the elastic restoring portion 545 is in a stationary state with respect to the first output shaft 539A or with respect to the floating shaft 543.
In the present disclosure, the shape of the center hole of the flap portion 547 is the same as or adapted to the shape of the cross section of the lower end of the first output shaft 539A so that the flap portion 547 can rotate in synchronization with the first output shaft 539A.

However, in consideration of space, a structure is adopted in which a lifting driving device in the form of a motor is used and the link is driven to swing up and down by a small-angle rotation of an output shaft of the motor, and this structure is preferably adopted.
In order to reduce the friction force during the contact between the connecting rod 5482 and the lifting bracket 542, the other end of the connecting rod 5482 is provided with a rolling device 5483, the rolling device 5483 is in contact with the lifting bracket 542, for example, the rolling device 5483 may be a bearing, a roller, or the like.
Also, a limit groove is formed in the lifting bracket 542, and the other end of the link 5482 or the rolling means 5483 moves in the limit groove, so that the movement stroke of the lifting bracket 542 when moving downward can be limited by the provision of the limit groove.

The detailed structure of the scrubbing unit 510 of the present disclosure will be described below with reference to the accompanying drawings.
Specifically, as shown in fig. 30, the scrubbing element 510 may include a first rotating member 511 and a second rotating member 512.
The first rotary member 511 is rotatable about a first rotation center 517 and forms a first rotation circumference. The second rotating member 512 may rotate about a second center of rotation 518 and form a second circle of rotation.
First rotating member 511 may have a first edge formed by first arc segment 513 and second arc segment 514. First arc segments 513 and second arc segments 514 are alternately connected end-to-end to form a first edge.
Fig. 30 shows that the number of first arc segments 513 and second arc segments 514 is four, respectively, and four first arc segments 513 and four second arc segments 514 are alternately connected to form a first edge.
It will be appreciated by those skilled in the art that the number of first arc segments 513 and second arc segments 514 may be other numbers, such as five, six, seven, eight, etc.
The second rotating member 512 may have a second edge, and the second edge is formed by a third arc segment 523 and a fourth arc segment 524. Although it is illustrated that the number of the third arc segments 523 and the number of the fourth arc segments 524 are four, respectively, and the four third arc segments 523 and the four fourth arc segments 524 are alternately connected to form the second edge, the second edge may include more than four third arc segments 523 and fourth arc segments 524, as the first edge is. In addition, the second rotating member 512 may have the same shape and arrangement as the first rotating member 511.
By the arrangement of the first and second rotating members 511 and 512 of the present disclosure, the first and second rotating members 511 and 512 may occupy a larger effective cleaning surface area. For example, a rotating member constructed with more than four arc segments will occupy a greater effective cleaning surface area than a triangular-like rotating member and will provide better results in an actual sweeping mopping process.
Further, although the arc segments of the first and second rotating members 511 and 512 are shown as circular arc shapes, they may have other arc shapes, for example, an arc shape having a straight line and a curved line.
The first rotating circle 515 and the second rotating circle 516 have an overlapping area, and the first edge and the second edge are kept in a state of being continuously tangent to each other at the edge and the inner portion of the overlapping area during the rotation of the first rotating member 511 and the second rotating member 512.
Wherein in the present disclosure, a state of continuous tangency refers to the first edge being in contact with the second edge or both maintaining a small gap, e.g., a constant small gap. In the present disclosure, the arcs of the first arc section, the second arc section, the third arc section, and the fourth arc section are set not to form mutual interference in the form of extrusion, etc., thereby ensuring smooth rotation of the first rotating member 511 and the second rotating member 512.
For example, in the case where the first and second edges are tangent, the sum of the distance from the first center of rotation 517 to the point of the tangent first/second arc and the distance from the second center of rotation 518 to the point of the tangent third/fourth arc will be equal or substantially equal to the distance between the first and second centers of rotation 517 and 518. During rotation of first and second rotating members 511, 512, the first arc segment generally mates with the fourth arc segment, and the second arc segment generally mates with the third arc segment. The distance from each point of the first arc segment and the third arc segment to the first rotation center is set to be greater than or equal to half the distance between the first rotation center 517 and the second rotation center 518, and the distance from each point of the second arc segment and the fourth arc segment to the first rotation center is set to be less than or equal to half the distance between the first rotation center 517 and the second rotation center 518.
As a specific example, the arrangement of the first to fourth arc segments may be as follows.
The first arc segment 513 is located at a distance from the first center of rotation 517: the distance between the center point or the middle area of the first arc section 513 and the first rotation center 517 is greater than the distance between the points at the two ends of the first arc section 513 and the first rotation center 517. The distances between each point of the first arc segment 513 and the first rotation center 517 gradually decrease from the center or middle region of the first arc segment 513 toward both ends of the first arc segment 513.
The distance of the third arc segment 523 from the second center of rotation 518 is set such that: the distance between the center point or the middle point of the third arc 523 and the second rotation center 518 is greater than the distance between the points at the two ends of the third arc 523 and the second rotation center 518. The distances between the points of the third arc segment 523 and the second rotation center 518 gradually decrease from the center or middle region of the third arc segment 523 toward both ends of the third arc segment 523.
The fourth arc segment 524 is spaced from the second center of rotation 518 by: the distance from the center point or middle area of the fourth arc 524 to the second rotation center 518 is smaller than the distance from the points at the two ends of the fourth arc 524 to the second rotation center 518. The distances between each point of the fourth arc segment 524 and the second center of rotation 518 gradually increase from the center or middle area of the fourth arc segment 524 toward the ends of the fourth arc segment 524.
In a preferred embodiment, the first arc segment 513 and the second arc segment 514 are smoothly transitioned arc segments, and/or the third arc segment 523 and the fourth arc segment 524 are smoothly transitioned arc segments.
When the scrubbing element 510 is in operation, it may be rotated horizontally to engage a surface to be cleaned for mopping, cleaning, or the like. The first and second rotating members 511 and 512 are symmetrically arranged and the rotating directions may be set to be opposite, so that it can be ensured that the rotation of the first and second rotating members 511 and 512 does not affect the normal traveling of the cleaning apparatus when the cleaning apparatus such as the automatic cleaning apparatus 10 is in operation.
In the embodiment of the present disclosure, the first rotating member 511 and the second rotating member 512 are configured to be movable up and down with respect to the surface to be cleaned. Wherein moving up and down here means moving in a direction perpendicular to the surface to be cleaned. In this manner, scrubbing elements 510 are brought into better contact with the surface being cleaned, thereby providing better cleaning.
The first rotating member 511 and the second rotating member 512 may be provided with a cleaning material to scrub the surface to be cleaned. The cleaning material may comprise, for example, a flexible brush head or cleaning cloth or the like. The cleaning head or head may scrub the surface being cleaned by the cleaning medium.
The cleaning material 519 is provided on the first rotating member 511 or the second rotating member 512, and the cleaning material 519 rotates as the first rotating member 511 and the second rotating member 512 rotate.
As shown in fig. 33, a hollowed-out area 525 may be provided on the first rotating member 511, so that when the cleaning liquid is supplied to the hollowed-out area 525, the cleaning liquid can pass through the hollowed-out area 525 to reach the cleaning material 519, thereby achieving a mopping effect of the automatic cleaning apparatus 10 by the wet cleaning material 519.
Although a hollowed-out area is shown in fig. 33, it will be appreciated by those skilled in the art that other shapes may be used.
In addition, the second rotating member 512 can also be used in the same manner, and is not described in detail herein.
