When the automatic cleaning apparatus 10 of the present disclosure is in use, both the dry cleaning device 300 and the wet cleaning device 500 can form a support to the housing assembly 100, that is, the support of the housing assembly 100 is achieved by a reaction force of a force applied to the surface to be cleaned by the dry cleaning device 300 and the wet cleaning device 500.

In an alternative embodiment of the present disclosure, the dry type cleaning device 300 is located in front of the wet type cleaning device 500 along the forward direction of the automatic cleaning device 10, that is, when the automatic cleaning device 10 performs a cleaning operation, after the surface to be cleaned is cleaned by the dry type cleaning device 300, the wet type cleaning device 500 performs a mopping cleaning operation, so as to reduce the accumulation of dirt on the wet type cleaning device 500, thereby reducing the number of times of cleaning the wet type cleaning device 500, or reducing the number of times of returning the automatic cleaning device 10 to the base station within a certain period of time, and increasing the single working time of the automatic cleaning device 10.

The detection device 600 is disposed on the housing assembly 100, and is configured to detect an obstacle around the automatic cleaning apparatus 10, so as to control the traveling device 200 of the automatic cleaning apparatus 10 to generate a corresponding motion when the detection device 600 confirms that the obstacle exists within the preset range around the automatic cleaning apparatus 10, so that the automatic cleaning apparatus 10 avoids the obstacle; as one implementation form, the detection device 600 may include a collision detection device 600, for example, when the automatic cleaning apparatus 10 collides with an obstacle, the running device 200 first generates a backward movement, and then turns and continues to advance so as to avoid the obstacle.

The respective devices of the automatic cleaning apparatus 10 will be described in detail below with reference to the accompanying drawings.

Fig. 3 is a schematic structural view of an upper housing portion according to one embodiment of the present disclosure. Fig. 4 is a schematic structural view of a lower housing portion according to one embodiment of the present disclosure.

As shown in fig. 1 to 4, the housing assembly 100 of the present disclosure may include an upper housing part 110 and a lower housing part 120, wherein the lower housing part 120 may be formed as a lower portion of the automatic cleaning apparatus 10 and as a support body of the automatic cleaning apparatus 10, which may cooperate with the upper housing part 110 described below to form a receiving space to receive a plurality of components of the automatic cleaning apparatus 10.

By providing the shielding member 140, the first and second rotary members 511 and 512 and the drive shaft which rotate can be protected, and objects such as cables on the ground can be prevented from being wound around the drive shaft. As shown in fig. 4, the shield member 140 is disposed to have a predetermined height from the cleaning surface, that is, the lower end of the shield member 140 is 0.5-1mm from the cleaning surface, which is less than the diameter of the charging wire, so that the electric wire can be blocked and friction with the ground can be also prevented. The protection component 140 may be formed by a soft material, and the soft material may be soft rubber, silica gel, rubber, or TPU, or the hardness of the soft material is about 50 °, for example, 40 ° to 60 °, so as to prevent the obstacle crossing of the automatic cleaning device from being affected by the existence of the protection component.

In the present disclosure, the first driving wheel assembly 210 further includes an odometer to detect a rotation angle of the traveling wheel 213 and/or the traveling driving device 211 by the odometer; and accurately determine the position and attitude of the automatic cleaning device 10 in the current working area based on the data detected by the odometer of the first drive wheel assembly 210 and the data detected by the odometer of the second drive wheel assembly 220, thereby making the automatic cleaning device 10 more intelligent.

More preferably, the first and second drive wheel assemblies 210 and 220 are rotatably provided to the lower housing part 120 such that the distance between the road wheels 213 and the lower housing part 120 is adjustable; for example, taking the first drive wheel assembly 210 as an example, the traveling gearbox housing 2121 of the traveling gear shifting mechanism 212 of the first drive wheel assembly 210 is rotatably disposed on the lower housing portion 120, and at this time, the first drive wheel assembly 210 and the second drive wheel assembly 220 form a biased falling suspension system and provide a biasing force through the traveling elastic portion.

That is, one end of the walking elastic part is fixed to the lower housing part 120, and the other end of the walking elastic part is fixed to the walking gearbox body 2121, such that the walking elastic part is located below the connection position of the walking gearbox body 2121 and the lower housing part 120, at this time, the walking elastic part is in a pre-stretched state, and in a free state, under the tensile force of the walking elastic part, the walking wheel 213 is spaced from the lower housing part 120 by a first distance; in the operating state, the road wheels 213 are spaced apart from the lower housing portion 120 by a second distance, wherein the first distance is greater than the second distance.

That is, the traveling wheels 213 are allowed to maintain contact and traction with the surface to be cleaned with a certain ground contact force while the dry type cleaning device 300 and the wet type cleaning device 500 of the automatic cleaning apparatus 10 contact the surface to be cleaned with a certain pressure by the arrangement of the traveling elastic parts (e.g., biasing springs).

Fig. 8 is a schematic structural view of an automatic cleaning apparatus according to an embodiment of the present disclosure.

The side brush driving device 312 is disposed on the lower housing portion 120 and is used for driving the side brush portion 311 to rotate, wherein the rotation axis of the side brush portion 311 is perpendicular or substantially perpendicular to the lower housing portion 120, that is, the rotation axis of the side brush portion 311 is perpendicular or substantially perpendicular to the surface to be cleaned when the automatic cleaning apparatus 10 is in operation.

In an alternative embodiment of the present disclosure, the number of the side brush cleaning assemblies 310 may be one, or may be two, and when the number of the side brush cleaning assemblies 310 is one, the side brush cleaning assemblies 310 are disposed in front of the first drive wheel assembly 210 or the second drive wheel assembly 220; when the number of the side brush cleaning assemblies 310 is two, the two side brush cleaning assemblies 310 are respectively disposed in front of the first and second driving wheel assemblies 210 and 220.

In the present disclosure, the roller brush cleaning assembly 320 is rotatably disposed on the housing assembly 100, for example, rotatably disposed on the lower housing part 120 of the housing assembly 100, and is used for performing dry cleaning, i.e., performing the second cleaning, on the surface to be cleaned; more preferably, the rolling brush cleaning assembly 320 is detachably disposed to the housing assembly 100, and the rolling brush cleaning assembly 320 can be detached from the housing assembly 100 by, for example, a manual switch.

The roll brush cleaning assembly 320 includes a roll brush portion 321, wherein the roll brush portion 321 is rotatably disposed at the lower housing portion 120, and cleans a surface to be cleaned by contact of a circumferential surface of the roll brush portion 321 with the surface to be cleaned.

The rolling brush part 321 includes a barrel part and a protruding part provided outside the barrel part, wherein the barrel part is rotatably provided to the lower housing part 120, and the cleaning of the surface to be cleaned is achieved by the contact of the protruding part of the rolling brush part 321 with the surface to be cleaned.

Wherein the protrusions may be formed in the form of bristles so that the rolling brush part 321 has an effect of sweeping the surface to be cleaned.

Preferably, as shown in fig. 7, the axis of rotation of the cartridge body is parallel or substantially parallel to the lower housing portion 120. In one implementation, the axis of rotation of the barrel is disposed forward of a line between the first drive wheel assembly 210 and the second drive wheel assembly 220. Of course, the position of the drum is not limited to this, and it may be disposed behind the line connecting the first driving wheel assembly 210 and the second driving wheel assembly 220.

In the present disclosure, the sweeping area of the side brush cleaning assembly 310 coincides with the sweeping area of the rolling brush cleaning assembly 320.

For example, as shown in fig. 7, when there are two side brush cleaning assemblies 310, two side brush cleaning assemblies 310 are located at both ends of the rolling brush cleaning assembly 320 in the length direction of the rolling brush cleaning assembly 320, and a projection of the side brush cleaning assembly 310 in the length direction of the rolling brush cleaning assembly 320 coincides with a portion of the rolling brush cleaning assembly 320.

Accordingly, when the side brush cleaning assembly 310 is one, the side brush cleaning assembly 310 is located at one end of the roller brush cleaning assembly 320 in the length direction of the roller brush cleaning assembly 320, and a projection of the side brush cleaning assembly 310 in the length direction of the roller brush cleaning assembly 320 coincides with a portion of the roller brush cleaning assembly 320.

Thus, when the edge brush cleaning assembly 310 rotates, light particles of dust and the like on the surface to be cleaned can be swept into the sweeping area of the roller brush cleaning assembly 320 and swept again by the roller brush cleaning assembly 320, thereby increasing the cleaning area of the automatic cleaning apparatus 10.

In the present disclosure, the rolling brush cleaning assembly 320 further includes a rolling brush driving device 322, and the rolling brush driving device 322 is used for driving the rolling brush part 321 to rotate, so as to clean the surface to be cleaned.

The dust container 410 is connected to the suction device 420, so that a negative pressure is generated in the dust container 410 by the suction device 420, thereby sucking dirt generated by the roller brush cleaning assembly 320 cleaning the surface to be cleaned into the dust 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 roll brush cleaning assembly 320, for example, a portion of the roll brush part 321 of the roll brush cleaning assembly 320, is located outside the dust collection part 430 through the opening, so that the roll brush part 321 of the roll brush cleaning assembly 320 comes into contact with a surface to be cleaned when the automatic cleaning apparatus 10 is in operation.

The portion of the dust collection part 430 located behind the roller brush cleaning assembly 320 is formed in a planar shape and is spaced apart from one end of the protruding part 321 of the roller brush cleaning assembly 320, which is away from the body part, to reduce resistance of the air flow inside the dust collection part 430 and allow the dirt carried in the air flow to be conveyed to the dust collection container 410.

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 view of a structure 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. 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 a negative pressure is generated inside the box portion 411 (for example, when the suction device 420 operates), the cover portion 412 opens the inlet of the box portion 411; when negative pressure is not generated inside the case portion 411 (e.g., 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 section 411 is smaller than the air pressure inside the dust collection section 430, and the absolute value of the difference between the air pressure inside the case section 411 and the air pressure inside the dust collection section 430 is equal to or greater than a preset value, the cover section 412 opens the inlet of the case section, otherwise, the cover section 412 closes the inlet of the case section 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, for convenience, the bottom wall of the first portion of the box portion 411 is the first bottom wall 4111 constituting the box portion 411, and the bottom wall of the second portion of the box portion 411 is the second bottom wall 4112 constituting the box portion 411, and the technical terms of the first bottom wall 4111 and the second bottom wall 4112 are used hereinafter to describe the disclosure.

Accordingly, the suction device is provided at the bottom wall of the second portion of the cartridge portion 411, i.e., the suction device 420 can be placed below the second bottom wall 4112 of the cartridge 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.

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.

In the present disclosure, as shown in fig. 17 and 18, a side wall of the case portion 411 is opened with a discharge port to discharge dirt inside the case portion 411 through the discharge port.

For example, as shown in fig. 8 and 11, the discharge port may be connected to one end of the cleaning pipe 450, and the other end of the cleaning pipe 450 may be connected to a cleaning device of a base station, so that the dirt in the dust collection container 410 is sucked out by the suction force of the cleaning device.

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 larger 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 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 solid waste is conveyed to the outside of the box portion 411 with the air flow.

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 blocking portion 414 through the torsion spring and to make the blocking portion 414 in a normally closed state.

Of course, the baffle portion 414 may be opened or closed by other structures, such as by means of 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 discharge port; 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 first bottom wall 4111 and/or the side wall of the box body 411 may form a limiting portion, and the baffle portion 414 is located outside the limiting portion to limit the baffle portion 414 from further moving to the inside of the box body 411 by the limiting portion, and thus the baffle portion 414 may not open the discharge port when negative pressure is generated inside the box body 411.

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; alternatively, the first bottom wall 4111 is formed as a step, and the step forms a limiting portion.

Preferably, the sealing member 416 is a ring-shaped sealing member, so that the gas is effectively prevented from entering the inside 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 the operating state.

In the present disclosure, the inner surface of the lower end of the discharge port is flush or substantially flush with the inner surface of the first bottom wall 4111, thereby providing a better soot cleaning effect.

The lower end of the rotating shaft portion is provided with a fastening member 546 to restrict a downward moving position of the first rotating member 511 in the axial direction of the rotating shaft portion by the fastening member 546; for example, when the first rotating member 511 contacts with the stopper portion of the rotating shaft portion, a preset distance, i.e., a movement stroke of the first rotating member 511 in the axial direction of the rotating shaft portion, is provided between the fastening member 546 and the first rotating member 511.

As one implementation form, the fastening element 546 includes a cap screw fixed to the lower end of the rotating shaft portion, at which time the lower end of the rotating shaft portion is opened with a threaded hole so that the cap screw can be screwed into the threaded hole of the rotating shaft portion, and when the first rotating member 511 is in contact with the limiting portion of the rotating shaft portion, a preset distance is provided between the head of the cap screw and the first rotating member 511; when the first rotating member 511 is in contact with the cap screw, at least a portion of the head of the cap screw is in contact with the first rotating member 511.

In the present disclosure, as shown in fig. 34, the floating shaft 543 is provided so as to be able to approach or separate from the first output shaft 539A of the speed shift device 530; wherein, the upper end of the floating shaft 543 or the lower end of the first output shaft 539A of the speed changing device 530 is provided with a guide hole, and when the lower end of the first output shaft 539A of the speed changing device 530 is provided with a guide hole, the upper end of the floating shaft 543 is slidably disposed in the guide hole of the first output shaft 539A of the speed changing device 530; accordingly, when the upper end of the floating shaft 543 is provided with the guide hole, the lower end of the first output shaft 539A of the speed shift device 530 is slidably disposed within the guide hole of the floating shaft 543 to enable the first output shaft 539A of the speed shift device 530 and the floating shaft 543 to slide, and thereby to enable the first output shaft 539A of the speed shift device 530 and the floating shaft 543 to approach or separate from each other.

The guide hole is a non-circular hole, for example, the shape of the guide hole can be square, triangular and the like; the shape of the upper end of the floating shaft 543 is adapted to the shape of the guide hole of the first output shaft 539A of the speed shift device 530, and the shape of the upper end of the floating shaft 543 is the same as the shape of the guide hole of the first output shaft 539A of the speed shift device 530, for example, so that power can be transmitted between the floating shaft 543 and the first output shaft 539A of the speed shift device 530.

Thereby, when the first rotating member 511 is applied with an external force from the surface to be cleaned, for example, when the surface to be cleaned is uneven, a relative movement can be generated between the floating shaft 543 and the first output shaft 539A of the speed changing device 530.

Also, the elastic restoring portion 545 is to provide a restoring force to the floating shaft 543, and for example, the elastic restoring portion 545 may provide a downward force to the floating shaft 543 and the first rotation member 511 mounted to the floating shaft 543, so that a predetermined positive pressure may be generated when the first rotation member 511 contacts the ground. More preferably, one end of the elastic restoring portion 545 does not rotate or the rotation angle is within a preset range with respect to the output shafts (the first output shaft 539A and the second output shaft 539B), and the other end of the elastic restoring portion does not rotate or the rotation angle is within a preset range with respect to the floating shaft.

The spring may be sleeved outside the first output shaft 539A, one end of the spring abuts against the floating shaft 543, the other end of the spring is fixed to the first output shaft 539A, and the spring is in a pre-compressed state, so that when the automatic cleaning apparatus 10 is placed on a surface to be cleaned, the first rotating member 511 applies a positive pressure to the surface to be cleaned.

In the present disclosure, in order to prevent the elastic restoring portion 545 from twisting during operation, the first output shaft 539A is provided with a stop portion 547, and the other end of the elastic restoring portion 545 is abutted against the stop portion 547, that is, the elastic restoring portion 545 is located between the floating shaft 543 and the stop portion 547, wherein the stop portion 547 rotates synchronously with the first output shaft 539A, so that the elastic restoring portion 545 is in a stationary state between the floating shaft 543 and the stop portion 547.

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 against 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.

Conversely, when the elevation driving means 5481 is reversely rotated, the elevation bracket 542 is moved downward by the gravity of itself and other components mounted to the elevation bracket 542.

Preferably, the length direction of the link 5482 is perpendicular to the rotation axis of the elevation drive means 5481, and the one end and the other end of the link 5482 refer to the one end and the other end of the length direction of the link 5482.

However, in consideration of space, a structure 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 rotation of an output shaft of the motor at a small angle is preferably used.

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 may rotate about a first rotation center 517 and form 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 rotation 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, 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 of 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.

First arc segments 513 are convex with respect to first center of rotation 517 and second arc segments 514 are concave with respect to first center of rotation 517. Third arc 523 is convex with respect to second center of rotation 518 and fourth arc 524 is concave with respect to second center of rotation 518.

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 segment, the second arc segment, the third arc segment, and the fourth arc segment 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 of a first edge and a second edge being tangent, the sum of the distance from the first center of rotation 517 to the point of the tangent first arc/second arc and the distance from the second center of rotation 518 to the point of the tangent third arc/fourth arc will be equal or substantially equal to the distance between the first center of rotation 517 and the second center of rotation 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 arc segment to the fourth arc segment 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.

Second arc segment 514 is spaced from first center of rotation 517 by: the distance from the center point or middle area of second arc 514 to first center of rotation 517 is less than the distance from the points at the two ends of second arc 514 to first center of rotation 517. The distances between each point of second arc segment 514 and first center of rotation 517 gradually increase from the center or middle region of second arc segment 514 toward the ends of second arc segment 514.

The distance of the third arc segment 523 from the second center of rotation 518 is set to: 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 distance between each point of the fourth arc segment 524 and the second center of rotation 518 increases from the center or middle region of the fourth arc segment 524 toward both 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 better contacted with the surface being cleaned, resulting in 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 cleaning surface with the cleaning substance.

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.

Therefore, when the automatic cleaning device stops at the base station, the liquid supplementing pipe of the base station can drive the liquid supplementing control part 572, and the accurate position of the liquid supplementing control part is obtained through the position detection module, so that the process of supplementing the cleaning liquid can be smoothly carried out.

Of course, the position detection module 610 may also be part of the detection device 600 of the automatic cleaning apparatus 10; that is, it is not inconsistent for those skilled in the art to classify the position detecting module 610 as the cleaning liquid supplying device or the detecting device.
