[0053] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure. In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present disclosure.

[0054] As shown in Figure 1-30, when a cleaning device such as a sweeper is working, the cleaned garbage is sucked into the built-in dust collection channel through the suction port, and is finally collected by the dust box. Since the suction port cannot cover the entire bottom of the sweeper body, when the sweeper moves close to the wall for cleaning or close to other obstacles for cleaning, there will be a blind spot between the edge of the sweeper and the wall. To solve this problem, the sweeper is equipped with a side brush assembly 10 to assist the main brush assembly located at the suction port for cleaning. It mainly cleans and pushes dirt close to the wall or other obstacles into the cleaning range of the main brush assembly so that it can be sucked into the suction port. It can also improve the cleaning efficiency of the sweeper to a certain extent.

[0055] In the related art, during the operation of the cleaning equipment, flexible garbage such as hair and thread on the ground are easily entangled on the side brush, which not only affects the cleaning effect, but also affects the normal use of the cleaning equipment. During daily maintenance, the hair on the side brush is also difficult to clean, affecting the user experience.

[0056] Based on the above technical problems, the present disclosure provides a side brush assembly 10, which aims to reduce or even avoid the phenomenon of flexible garbage being entangled on the side brush to at least a certain extent, so as to improve the cleaning effect, enable the cleaning equipment to be used normally, and make it easy to clean the side brush to improve the user experience.

[0057] In conjunction with Figures 1 and 2, the present disclosure provides a side brush assembly 10, which includes a base 1 and a side brush member 2. The side brush member 2 is connected to the base 1, and the side brush member 2 includes bristles 22. A blocking portion 3 is provided on the side brush member 2, and the projection of the blocking portion 3 on the base 1 (horizontal direction) partially overlaps with the projection of the bristles 22 on the base 1 (horizontal direction) to prevent the hair wrapped around the side brush member 2 from entering the base 1 along the direction of the side brush member 2.

[0058] The side brush assembly 10 provided in the present disclosure has a blocking portion 3 provided on the side brush part 2, and the projection of the blocking portion 3 on the base 1 partially coincides with the projection of the bristles 22 on the base 1, that is, the blocking portion 3 protrudes from the periphery of the bristles 22. During the rotation of the side brush assembly 10, if flexible garbage such as hair and thread is entangled on a side brush, due to the setting of the blocking portion 3, the hair entangled on the side brush part 2 can be prevented from entering the base 1 along the direction of the side brush part 2, and then the transmission shaft of the cleaning device connected to the base 1 can be prevented from being entangled by flexible garbage such as hair and thread, resulting in a stoppage, so as to avoid affecting the cleaning effect and enable the cleaning device to be used normally to improve the user experience.

[0059] In conjunction with Figure 1, in some embodiments, the base 1 is used to connect to the drive shaft of the drive motor on the cleaning device, and a mounting hole 11 is provided in the center thereof. The drive shaft of the drive motor on the cleaning device is fixedly assembled in the mounting hole 11 of the base 1. The base 1 of the side brush assembly 10 and the drive shaft of the drive motor rotate synchronously, thereby realizing the rotation of the side brush assembly 10.

[0060] With reference to FIG1 , in some embodiments, the mounting hole 11 can be a regular polygon. Accordingly, the portion where the drive shaft of the drive motor is mounted within the mounting hole 11 can also be a regular polygon, thereby securing the two relative to each other and preventing relative rotation therebetween. In other embodiments, the mounting hole 11 can also be a non-circular structure, such as a trapezoid or ellipse, and the portion where the drive shaft of the drive motor is mounted within the mounting hole 11 can be adaptively designed.

[0061] It should be noted that the base 1 can also be directly fixedly connected to the driving shaft of the driving motor, for example, by using key connection, bolt locking, etc., which is not limited here.

[0062] In conjunction with Figures 1 to 3, in some embodiments, since the base 1 is used to connect to the drive shaft of the drive motor on the cleaning equipment, it needs to have a certain strength for use. Therefore, in the embodiment of the present disclosure, a ring structure 4 can be provided on the top of the base 1 and a spherical structure 5 can be provided on the bottom to strengthen the structure of the base 1.

[0063] In some embodiments, the annular structure 4 and the spherical structure 5 can be integrally formed with the base 1, wherein the annular structure 4 can be concentrically or eccentrically arranged on the outside of the driving hole, and a circular positioning hole 51 is provided on the spherical structure 5, and the head of the driving shaft of the driving motor can be arranged in the positioning hole 51 of the spherical structure 5.

[0064] It should be noted that reinforcement structures of other shapes may also be provided on the top and / or bottom of the base 1 , which is not limited here.

[0065] 1-3 , in some embodiments, three side brushes 2 may be provided, and the three side brushes 2 may be evenly spaced around the circumference of the base 1 to ensure sufficient cleaning coverage of the side brush assembly 10. In other embodiments, one, two, four, or five side brushes 2 may be provided. If more than two side brushes 2 are provided, multiple side brushes 2 may also be unequally spaced around the circumference of the base 1, without limitation.

[0066] In conjunction with Figures 1 to 3, in some embodiments, the side brush 2 may include a side brush arm 21 and bristles 22, wherein one end of the side brush arm 21 is connected to the base 1, and the other end of the side brush arm 21 extends away from the base 1, and the bristles 22 are connected to the other end of the side brush arm 21 and extend away from the side brush arm 21. The part of the floor cleaned by the bristles 22 can be defined as the cleaning end of the side brush 2, and the above-mentioned blocking portion 3 is arranged on the side brush arm 21.

[0067] 1 to 3 , in some embodiments, a blocking protrusion 32 may be provided on the side brush arm 21 , and the blocking protrusion 32 may be configured as the blocking portion 3 .

[0068] 1-3 , in some embodiments, the blocking portion 3 may be provided with a recess 31, with the open side of the recess 31 facing the bristles 22. If hair, thread, or other flexible debris becomes entangled with the side brush 2, it will accumulate in the recess 31 of the blocking portion 3. The recess 31 can, to a certain extent, restrict the movement path of the hair, thread, or other flexible debris, further preventing the hair from moving from the side brush 2 to other locations, such as the base 1, or to components of the cleaning device adjacent to the side brush 2, thereby preventing the cleaning device from malfunctioning.

[0069] In some embodiments, the opening side of the recess 31 has an angle greater than or equal to 90°, so that the blocking portion 3 has a sufficiently large accommodation space to prevent flexible garbage such as hair, thread, etc. on the side brush 2 from entering the base 1 along the direction of the side brush 2.

[0070] In other embodiments, the angle formed by the open side of the recess 31 may also be an acute angle, which can also prevent flexible garbage such as hair and thread on the side brush 2 from entering the base 1 along the direction of the side brush 2.

[0071] 3 , in a specific implementation, the blocking protrusion 32 may be provided at the other end close to the side brush arm 21 to extend the distance between the hair and the base 1 to a certain extent, thereby preventing the hair protruding from the blocking portion 3 from contacting the base 1 and being drawn into the base 1 . The top of the second bevel 312 is provided with a second bevel 312, and the bottom end of the first bevel 311 and the top end of the second bevel 312 intersect to form the two side portions of the above-mentioned recess 31. The first bevel 311 and the second bevel 312 are configured to form the two side portions of the recess 31. The first bevel 311 and the second bevel 312 are configured to form the two side walls of the recess 31. The angle between the first bevel 311 and the second bevel 312 forms the angle of the opening side of the recess 31.

[0072] In other embodiments, only the above-mentioned first inclined surface 311 or only the above-mentioned second inclined surface 312 may be provided, and the technical effect of the angle between the bottom of the other end of the side brush arm 21 and the side of the blocking protrusion 32 facing the bristles 22 being greater than or equal to 90° can also be achieved, which will not be elaborated here.

[0073] It should be noted that the blocking portion 3 can also be set in the middle of the side brush arm 21, or can be set at the top of the side brush arm 21. For example, a circumferential protrusion extending outward is provided on the circumferential surface of the middle of the side brush arm 21, and the circumferential protrusion can be configured as the above-mentioned blocking portion 3, which is not limited here.

[0074] In conjunction with Figure 3, in some embodiments, the side brush arm 21 may include multiple arm sections, and among the multiple arm sections, the thickness of at least two arm sections is different, so that the side brush arm 21 has a certain deformation ability. This is because: the side brush arm 21 is usually made of soft rubber material, and the cleaning end of the side brush part 2 will be deformed when it contacts the cleaning ground, but the side brush arm 21 needs to maintain a certain connection strength. Therefore, the side brush arm 21 can be divided into multiple arm sections, and the thickness of at least two arm sections is different to meet the above requirements.

[0075] 3 , the thickness of the multi-segment arm can gradually decrease in the direction away from the base 1. In addition, the thickness of at least part of the middle portion of the side brush arm 21 gradually changes from thick to thin in the direction away from the base 1, so that the strength of this portion is reduced and the elasticity is enhanced.

[0076] 3 , in specific implementation, the side brush arm 21 may include three arm sections, namely a first arm 211 connected to the base 1, a third arm 213 connected to the bristles 22, and a second arm 212 connecting the first arm 211 and the third arm 213. The first arm 211 has a relatively thick arm thickness to have sufficient connection strength for use, the second arm 212 has a thickness that gradually changes from thick to thin, the strength of the second arm 212 gradually decreases, and the elasticity gradually increases, so as to serve as the starting point of the deformation position of the side brush assembly 10 when it rotates. The third arm 213 has a relatively thin arm thickness to have sufficient elasticity to adapt to the deformation caused by the contact between the cleaning end of the side brush 2 and the cleaning ground.

[0077] In some embodiments, the multiple arm sections constituting the side brush arm 21 can be integrally formed. Since the side brush arm 21 is made of soft rubber and the base 1 is made of hard rubber, the side brush arm 21 can be formed on the circumference of the base 1 by secondary injection molding. In other embodiments, the side brush arm 21 can also be connected to the circumference of the base 1 by plugging or other means, which is not limited here.

[0078] 2 , in some embodiments, the bristles 22 are connected to the blocking protrusion 32 and extend obliquely downward. Furthermore, the bristles 22 can be inclined at an angle of 40-60°, that is, the bristles 22 can be at an angle of 40-60° relative to the plane of the base 1. This ensures that the cleaning coverage of the side brush assembly 10 meets the requirements while effectively preventing hair entanglement. For example, the inclination angle of the bristles 22 can be 40°, 60°, or even 45°, without limitation.

[0079] In addition, in some embodiments, in order to achieve a better cleaning effect, the length of the bristles 22 needs to be set. The length of the bristles 22 can be within 20-60 mm to ensure that the cleaning coverage of the side brush assembly 10 meets the requirements and has a better effect of preventing hair entanglement. For example, the length of the bristles 22 can be 20 mm, 40 mm or 60 mm, which is not limited here.

[0080] 4 , in some embodiments, the projections of the side brush arms 21 of the multiple side brush members 2 on the plane of the base 1 may be in the form of a spiral involute. When the side brush assembly 10 rotates, if there is hair on the side brush member 2, a centrifugal force is generated on the hair, causing the hair to be thrown out under the action of the centrifugal force, thereby preventing the hair from being entangled on the side brush member 2 to a certain extent. If the hair on the side brush member 2 is not thrown out, the blocking portion 3 on the side brush member 2 can prevent the hair entangled on the side brush member 2 from entering the base 1 along the direction of the side brush member 2. This can prevent the drive shaft of the cleaning device connected to the base 1 from being entangled by the hair and causing it to stop rotating, thereby avoiding affecting the cleaning effect and allowing the cleaning device to be used normally.

[0081] 5 , when the bristle assembly 22 of the present disclosure rotates counterclockwise, hair, thread, and other flexible debris entangled with the bristles 22 generates a clockwise centrifugal force. Under the action of this centrifugal force, the hair, thread, and other flexible debris on the bristles 22 are flung out and automatically detached from the bristles 22, thereby preventing the hair, thread, and other flexible debris from becoming entangled in the side brush member 2 to a certain extent. If the hair on the side brush member 2 is not flung out, the hair will accumulate on the barrier 3 provided on the side brush member 2. Since the centrifugal force of an object is proportional to its mass, when the hair, thread, and other flexible debris accumulate to a certain mass, the side brush assembly 10, when rotating at an accelerated speed, such as when moving along a wall, generates sufficient centrifugal force to flung out the hair, thread, and other flexible debris, automatically detaching the hair, thereby preventing the hair from affecting the normal operation of the device and ensuring a good cleaning effect. This also avoids the need for the user to manually clean the hair, thereby improving the user experience.

[0082] In some embodiments, the bristles 22 and the connected side brush arm 21 can be arranged tangentially on the plane where the base 1 is located to ensure that during the operation of the side brush assembly 10, the bristles 22 can produce enough deformation with the ground to throw away flexible garbage such as hair and thread on the bristles 22.

[0083] It should be noted that if there is an extremely bad situation, flexible garbage such as hair and thread cannot be brushed out from the bristles 22, but accumulates on the blocking part 3. When cleaning the hair, the user can quickly clean the hair and other flexible garbage accumulated on the blocking part 3 at one time, which is convenient and fast, and can also improve the user experience.

[0084] As shown in Figures 6 to 12, an embodiment of the present disclosure provides a side brush assembly 10. The side brush assembly 10 is applied to a cleaning device, wherein the cleaning device can be a sweeping (cleaning) robot, a sweeping and mopping machine, or other cleaning devices that meet the requirements.

[0085] Specifically, the cleaning device includes, but is not limited to, a mobile host 9, a cleaning system, and a drive system. These systems coordinate with each other, enabling the cleaning device to autonomously move and perform its cleaning functions. The functional components of the cleaning device, including the components of the aforementioned systems, are integrated within the mobile host 9. It is understood that the cleaning device may be a self-propelled cleaning device, which automatically cleans an area to be cleaned without user intervention.

[0086] The mobile host 9 includes a forward portion and a rearward portion, and has an approximately circular shape or other shapes, including but not limited to an approximately D-shaped shape with a front and rear circular portion, and a rectangular or square shape with a front and rear circular portion.

[0087] The cleaning system includes a dry cleaning system, that is, the cleaning device may be a sweeping robot, or the cleaning system includes a wet cleaning system and a dry cleaning system, that is, the cleaning device may be a sweeping and mopping machine.

[0088] The dry cleaning system includes a roller brush, a dust box, and a dust suction fan. The roller brush, which has a certain degree of contact with the ground, sweeps up debris from the ground and carries it to the front of the dust suction port between the roller brush and the dust box. The dust is then sucked into the dust box by the suction air generated by the dust suction fan and passed through the dust box.

[0089] Furthermore, the cleaning device provided by the embodiment of the present disclosure, the cleaning system may also include a side brush assembly 10, which is rotatably connected to the mobile host 9 and is used to move debris and other sundries outside the roller brush area into the roller brush area of ​​the cleaning system.

[0090] Currently, the side brush assembly 10 in the related art is usually configured as a three-claw structure, that is, the side brush assembly 10 usually includes three side brush arms 21 and three bristles 22. The side brush arms 21 are symmetrically arranged around the base 1. During assembly, one bristle 22 is exposed to the outside of the mobile main unit 9. In this way, during the rotation of the side brush, the three bristles 22 rotate to the outside of the mobile main unit 9 in sequence to expand the cleaning range and achieve the function of auxiliary cleaning. However, with this configuration, when the side brush assembly 10 is not working, one bristle 22 is still exposed to the outside of the mobile main unit 9, making the overall size of the cleaning device larger and inconvenient to store and move.

[0091] In view of this, as shown in Figures 6, 7 and 8, the side brush assembly 10 provided in the embodiment of the first aspect of the present disclosure includes: a base 1, a side brush arm 21 and bristles 22, the side brush arm 21 is distributed around the base 1, the bristles 22 are connected to the end of the side brush arm 21 away from the base 1, and the base 1 is configured to be connected to the driving assembly of the cleaning equipment so that the driving assembly drives the base 1 to rotate; the side brush arm 21 has an asymmetric structure around the base 1.

[0092] Among them, the driving component can be installed on the mobile host 9 of the cleaning equipment, and the base 1 is connected to the driving component, so that the driving component can drive the base 1 to rotate relative to the mobile host 9. Since the bristles 22 are connected to the base 1 through the side brush arm 21, the rotation of the base 1 can drive the side brush arm 21 and the bristles 22 to rotate synchronously, so that the bristles 22 can guide debris and other debris outside the roller brush area into the roller brush area of ​​the cleaning system, thereby achieving the role of auxiliary cleaning and improving the cleaning effect of the cleaning equipment.

[0093] In this embodiment, the side brush arms 21 have an asymmetric structure around the circumference of the base 1. It is understood that the bristles 22 are arranged corresponding to the side brush arms 21, and the number of bristles 22 is the same as that of the side brush arms 21, that is, the bristles 22 have an asymmetric structure around the circumference of the base 1. This arrangement allows the bristles 22 to be more concentratedly distributed on a portion of the circumference of the base 1, while another portion of the circumference of the base 1 is idle. Furthermore, for the same number of side brush arms 21, the idle area of ​​the side brush arms 21 around the circumference of the base 1 is larger when the side brush arms 21 are asymmetric than when they are symmetrical. Therefore, during the assembly process of the side brush assembly 10 and the mobile host 9, the relative positions of the side brush arm 21, the bristles 22 and the mobile host 9 can be reasonably adjusted so that the idle part on the side of the base 1 faces the outside of the edge of the nearby part of the mobile host 9, so that the side brush arm 21 and the bristles 22 are all located within the edge projection area of ​​the mobile host 9, that is, the projection of the side brush arm 21 and the bristles 22 on the horizontal plane is located within the area of ​​the projection of the mobile host 9 on the horizontal plane. Compared with the related technology in which the side brush arm 21 with a three-claw structure and a symmetrical structure on the side of the base 1 have part of the bristles 22 exposed to the outside of the mobile host 9, the space occupied by the cleaning equipment can be reduced, making the cleaning equipment easier to store, avoid obstacles, and put on and take off piles. At the same time, the appearance is neater, which improves market competitiveness.

[0094] Specifically, in the related art, the three-claw side brush structure is usually arranged so that the three side brush arms 21 are symmetrically arranged around the base 1, that is, the angle between the midlines of two adjacent side brush arms 21 is 120°. Therefore, when the width of the side brush arms 21 is ignored, the angle of the space around the base 1 is approximately 120°. In this embodiment, the side brush arms 21 are asymmetrically arranged around the base 1. For example, the three side brush arms 21 are asymmetrically arranged around the base 1. When the width of the side brush arms 21 is ignored, the angle of the space around the base 1 is greater than 120°. Alternatively, when the number of side brush arms 21 is greater than or less than three, the position of the side brush arms 21 around the base 1 can be reasonably set so that the angle of the space around the base 1 is greater than 120° when the width of the side brush arms 21 is ignored. In this way, during the assembly of the side brush assembly 10 and the mobile main unit 9, the relative positions of the side brush arm 21, the bristles 22, and the mobile main unit 9 can be reasonably adjusted so that the idle portion of the base 1 is oriented toward the outside of the edge of the adjacent portion of the mobile main unit 9, thereby ensuring that the side brush arm 21 and the bristles 22 are all located within the edge projection area of ​​the mobile main unit 9, and the bristles 22 are not exposed to the outside of the mobile main unit 9, thereby reducing the space occupied by the cleaning device. It is understandable that when the base 1 rotates with the drive assembly, the bristles 22 will extend outside the edge projection area of ​​the mobile main unit 9 to expand the cleaning range and achieve the function of auxiliary cleaning.

[0095] In some possible embodiments provided by the present disclosure, the number of side brush arms 21 is set to one or two. It can be understood that the number of bristles 22 is the same as the number of side brush arms 21, that is, the number of bristles 22 is one or two. Compared with the three-claw side brush in the related art, this arrangement enables the bristles 22 to be distributed more concentratedly on part of the circumference of the base 1, while the other part of the circumference of the base 1 is idle, and the idle part of the circumference of the base 1 is larger than that of the three-claw side brush. Therefore, during the assembly of the side brush assembly 10 and the mobile host 9, the relative positions of the side brush arm 21, the bristles 22 and the mobile host 9 can be reasonably adjusted so that the idle part of the circumference of the base 1 faces the outside of the edge of the nearby part of the mobile host 9, so that the side brush arm 21 and the bristles 22 are all located in the edge projection area of ​​the mobile host 9, that is, the projection of the side brush arm 21 and the bristles 22 in the horizontal plane is located in the area of ​​the projection of the mobile host 9 in the horizontal plane. Compared with the three-claw side brush in the related art where the bristles 22 are exposed to the outside of the mobile host 9, the space occupied by the cleaning equipment can be reduced, making the cleaning equipment easier to store, avoid obstacles, and get on and off piles. At the same time, the appearance is neater, which improves market competitiveness.

[0096] Specifically, in related art three-claw side brushes, typically, the three side brush arms 21 are evenly distributed around the base 1, meaning the angle between the midlines of two adjacent side brush arms 21 is 120°. Therefore, ignoring the width of the side brush arms 21, the angle of the free space around the base 1 is approximately 120°. In contrast, in this embodiment, when there is only one side brush arm 21, ignoring the width of the side brush arm 21, the angle of the free space around the base 1 is approximately 360°, which is significantly greater than the angle of the free space around the base 1 in a three-claw side brush. When there are two side brush arms 21, if the two side brush arms 21 are arranged around the base 1 at their maximum angle of 180°, ignoring the width of the side brush arms 21, the angle of the free space around the base 1 is approximately 180°, which is also significantly greater than the angle of the free space around the base 1 in a three-claw side brush. Therefore, since the angle of the spatial portion of the peripheral side of the base 1 of the side brush assembly 10 in this embodiment is relatively large, during the assembly process of the side brush assembly 10 and the mobile host 9, the relative positions of the side brush arm 21, the bristles 22 and the mobile host 9 can be reasonably adjusted so that the idle portion of the peripheral side of the base 1 faces the outside of the edge of the adjacent portion of the mobile host 9, thereby ensuring that the side brush arm 21 and the bristles 22 are both located within the edge projection area of ​​the mobile host 9, and the bristles 22 are not exposed to the outside of the mobile host 9, thereby reducing the space occupied by the cleaning equipment. It is understandable that when the base 1 rotates with the drive assembly, the bristles 22 will extend outside the edge projection area of ​​the mobile host 9 to increase the cleaning range and achieve the function of auxiliary cleaning.

[0097] In some possible embodiments provided by the present disclosure, the base 1 is provided with a first installation indicator 12, and the drive assembly is provided with a second installation indicator. The first installation indicator 12 matches the second installation indicator to indicate that the base 1 is in the installation position.

[0098] In this embodiment, a first installation indicator 12 is provided on the base 1 and a second installation indicator is provided on the drive assembly. During the process of connecting and assembling the side brush assembly 10 and the drive assembly, when the first installation indicator 12 matches the second installation indicator, it indicates that the base 1 is in the installation position. The base 1 can be connected to the drive assembly in this posture to realize the connection and assembly of the side brush assembly 10 and the drive assembly.

[0099] Furthermore, when the base 1 is in the installation position, the bristles 22 are located within the edge projection area of ​​the mobile host 9 of the cleaning device, that is, the bristles 22 do not extend beyond the edge projection area of ​​the mobile host 9. Therefore, compared with the related art in which part of the bristles 22 are exposed to the outside of the mobile host 9, the overall volume of the cleaning device when the base 1 is in the installation position is reduced, thereby reducing the space occupied by the cleaning device when the base 1 is in the installation position, making it easy to store the cleaning device, avoid obstacles, and put it on and off the pile when the base 1 is in the installation position. At the same time, the appearance is neater, thereby improving market competitiveness.

[0100] When the base 1 is in the installed position, the bristles 22 are located within the projection area of ​​the edge of the mobile main unit 9 of the cleaning device. This can be understood as the projection of the bristles 22 on the horizontal plane being located within the projection area of ​​the mobile main unit 9 on the horizontal plane. The base 1 also includes a working position relative to the mobile main unit 9, in which some of the bristles 22 are located outside the mobile main unit 9. That is, when the base 1 is in the working position, at least some of the bristles 22 are located within the projection area of ​​the edge of the mobile main unit 9 of the cleaning device. This can be understood as the projection of some of the bristles 22 on the horizontal plane being located outside the projection area of ​​the mobile main unit 9 on the horizontal plane; alternatively, all of the bristles 22 are located outside the projection area of ​​the mobile main unit 9 on the horizontal plane. In this example, the side brush assembly 10 can be configured as a telescopic structure relative to the mobile main unit 9, such that when the base 1 is in the installed position, the entire side brush assembly 10 can be retracted into the projection area of ​​the edge of the mobile main unit 9. When the base 1 is in the working position, all of the bristles 22 can be extended outside the projection area of ​​the edge of the mobile main unit 9. Specifically, when the base 1 is in the working position, the cleaning device can utilize the side brush assembly 10 for auxiliary cleaning. When the base 1 is in the installed position, the cleaning device can perform auxiliary cleaning without using the side brush assembly 10. The cleaning device can be in the storage position, perform obstacle avoidance operations, and perform auxiliary operations such as charging, dust collection, and water replenishment on the pile. The pile mentioned in this disclosure can be understood as a charging pile, dust collection pile, base station 20, etc. used in conjunction with the cleaning device.

[0101] Furthermore, by providing a first mounting indicator 12 on the base 1, since the relative position of the first mounting indicator 12 and the side brush arm 21 is known during the design process, the relative position of the bristles 22 and the side brush arm 21 is also known during the design process. Therefore, by matching the first mounting indicator 12 with the second mounting indicator on the drive assembly, the position of the side brush arm 21 and the bristles 22 relative to the mobile host 9 can be restricted, so that when the base 1 is in the installation position, the bristles 22 are located within the edge projection area of ​​the mobile host 9.

[0102] Furthermore, the first installation indicator 12 and the second installation indicator cooperate to limit the rotation of the base 1 relative to the mobile host 9, so that the base 1 can remain in the installed position relative to the mobile host 9 when the drive assembly is not working. Specifically, the drive assembly can be a motor, and the output shaft of the motor is connected to the base 1. The motor can be provided with a locking mechanism to ensure that the output shaft does not rotate when the motor is not working, so that after the output shaft and the base 1 cooperate with the first installation indicator 12 and the second installation indicator to place the base 1 in the installed position, the base 1 can be maintained in the installed position, thereby avoiding the situation where the base 1 can rotate relative to the output shaft when the motor is not working, causing the bristles 22 to extend outside the projection area of ​​the edge of the mobile host 9.

[0103] As shown in Figures 6, 7, 8 and 9, in some possible embodiments provided by the present disclosure, the base 1 is provided with a mounting hole 11 for connecting to the drive assembly, and the first mounting indicator 12 is arranged on the hole wall of the mounting hole 11. Therefore, when the base 1 is connected to the drive assembly through the mounting hole 11, the first mounting indicator 12 located on the hole wall of the mounting hole 11 matches the second mounting indicator on the drive assembly, which plays a role in limiting and preventing mistakes, and can accurately and conveniently indicate that the base 1 is in the installation position.

[0104] Among them, one of the first installation indicator 12 and the second installation indicator is configured as a recessed portion, and the other is configured as a convex portion. The recessed portion and the convex portion are convenient to process and easy to implement, which is conducive to reducing the overall processing cost of the side brush assembly 10. At the same time, the recessed portion and the convex portion have a good limit and anti-mistake effect, and are easy to assemble. They can accurately, conveniently and quickly indicate that the base 1 is in the installation position, which is suitable for popularization and application.

[0105] Specifically, the first installation indicator 12 may be a convex portion, and the second installation indicator may be a concave portion, or the first installation indicator 12 may be a concave portion, and the second installation indicator may be a convex portion. It is understood that in some examples, the first installation indicator 12 may include a concave portion and a convex portion, and the second installation indicator may also include a corresponding convex portion and concave portion, thereby meeting the requirements of different structures of the first installation indicator 12 and the second installation indicator.

[0106] Furthermore, the drive assembly includes a motor, and the output shaft of the motor is connected to the base 1 through the mounting hole 11, that is, the second mounting indicator can be set on the output shaft. Specifically, the first mounting indicator 12 can be a convex structure, and the second mounting indicator can be a groove structure.

[0107] As shown in Figures 8 and 9, in some possible embodiments provided by the present disclosure, the side brush assembly 10 further includes: a connector 62, the mounting hole 11 includes a first hole segment 111 and a second hole segment 112 along the axial direction of the base 1, the first hole segment 111 is located above the second hole segment 112 and matches the drive assembly, the first installation indicator 12 is provided in the first hole segment 111, and the connector 62 is provided in the second hole segment 112 and connected to the drive assembly. The axial direction of the base 1 can be the direction shown by arrow Z in Figure 9.

[0108] Therefore, during the assembly process of the side brush assembly 10 and the drive assembly, the first hole section 111 is first matched with the drive assembly for preliminary pre-positioning, and then the first installation indicator 12 of the first hole section 111 is matched with the second installation indicator on the drive assembly to achieve a position limiting and foolproof function, and accurately position the assembly of the base 1 and the drive assembly, so that the base 1 can be accurately and quickly placed in the installation position, ensuring that the bristles 22 are located within the edge projection area of ​​the mobile main unit 9. Then, the connecting member 62 is passed through the second hole section 112 to connect with the drive assembly, thereby achieving a reliable connection between the base 1 and the drive assembly. The operation is simple and helps to improve the assembly efficiency and assembly accuracy of the base 1 and the drive assembly.

[0109] Specifically, the first hole section 111 can be polygonal, and the output shaft of the drive assembly can be polygonal. Thus, the polygonal hole and the polygonal shaft cooperate to provide a good limiting effect, capable of limiting the rotation of the base 1 relative to the output shaft, ensuring that the base 1 and the output shaft can rotate synchronously. Specifically, the first hole section 111 can be hexagonal, and the output shaft of the drive assembly can also be hexagonal. It is understood that the first hole section 111 can also have other shapes.

[0110] Among them, the opening size of the first hole segment 111 can be larger than the opening size of the second hole segment 112. For example, the connecting piece 62 can be a bolt, and the second hole segment 112 can be circular. The opening size of the first hole segment 111 can be understood as the radial size of the second hole segment 112. A threaded hole is provided at the end of the output shaft of the drive assembly. The bolt passes through the second hole segment 112 and is connected to the threaded hole, so that the output shaft and the base 1 can be connected.

[0111] As shown in FIG. 9 , in some possible embodiments provided by the present disclosure, the mounting hole 11 further includes a third hole section 113 located below the second hole section 112 , and the end of the connecting member 62 away from the drive assembly is accommodated in the third hole section 113 .

[0112] In this embodiment, the setting of the third hole section 113 provides an accommodation space for the end of the connecting member 62 away from the driving assembly, so that the connecting member 62 does not protrude from the bottom of the base 1. As a result, the problem that the connecting member 62 protrudes from the bottom of the base 1, such as hair, wires and other debris, is easily entangled on the connecting member 62, causing the connecting member 62 to be difficult to disassemble or stuck, can be reduced or avoided, thereby reducing the interference of hair, wires and other debris on the connecting member 62, so that the connecting member 62 can be quickly and conveniently disassembled, thereby improving the disassembly efficiency and maintenance efficiency of the side brush assembly 10, and ensuring that the side brush assembly 10 can work reliably.

[0113] Specifically, the opening size of the third hole segment 113 can be larger than the opening size of the second hole segment 112. The second hole segment 112 can be circular, and the opening size of the third hole segment 113 can be understood as the radial size of the second hole segment 112. The connecting member 62 can be a bolt, and the head of the bolt is received in the third hole segment 113 so that the bolt does not protrude from the bottom of the base 1, reducing or preventing the bolt head from being entangled by hair.

[0114] As shown in Figures 6, 7, and 10, in some possible embodiments provided by the present disclosure, there are two side brush arms 21, each of which is spiral-shaped, and the bristles 22 correspond to the side brush arms 21, that is, there are two bristles 22 connected to the corresponding side brush arms 21. The bristles 22 extend along the tangent direction of the side brush arm 21, and the angle between the extension directions of the two bristles 22 is no greater than 120°.

[0115] The two side brush arms 21 and the two bristles 22 can ensure that the side brush assembly 10 has a larger cleaning range, which is conducive to ensuring a good cleaning effect.

[0116] The angle between the extension directions of the two bristles 22 can be shown as angle α in FIG. 10 , i.e., α is less than or equal to 120°. This allows the two side brush arms 21 and the two bristles 22 to be more concentratedly distributed along a portion of the circumference of the base 1, while another portion of the circumference of the base 1 is free and devoid of side brush arms 21 and bristles 22. Thus, by properly positioning the base 1, when the base 1 is in the installed position, the side brush arms 21 and bristles 22 are positioned near the interior of the mobile main unit 9, while the free portion of the base 1 faces the exterior of the mobile main unit 9, ensuring that the two bristles 22 are located within the edge projection of the mobile main unit 9. Furthermore, the base 1 can be positioned near the bottom edge of the mobile main unit 9, ensuring that the bristles 22 are located within the edge projection of the mobile main unit 9 when the base 1 is in the installed position. When the base 1 is in the operating position, the bristles 22 can smoothly extend to the exterior of the mobile main unit 9, ensuring a larger cleaning range and facilitating the switching of the base 1 between the installed and operating positions.

[0117] Furthermore, since the side brush assembly 10 in the related art is usually installed near the edge of the bottom of the mobile main unit 9, if there are three side brush arms 21, one bristle 22 usually extends outside the edge projection area of ​​the mobile main unit 9, making the overall volume of the cleaning device larger, inconvenient to store and move, and having an untidy appearance. In this embodiment, by providing the side brush assembly 10 with two side brush arms 21, and the bristles 22 extending along the tangent direction of the side brush arms 21, the angle between the extension directions of the two bristles 22 is no more than 120°. As a result, without changing the original structure of the cleaning device, the side brush assembly 10 in this embodiment is matched with the first installation indicator 12 and the second installation indicator of the drive assembly, so that the base 1 is in the installation position, and the bristles 22 are ensured to be located within the edge projection area of ​​the mobile main unit 9. This reduces the overall volume of the cleaning device, thereby reducing the space occupied by the cleaning device, making the cleaning device easier to store, easier to avoid obstacles, and easier to put on and take off when the base 1 is in the installation position. At the same time, the appearance of the cleaning device is more neat, improving its market competitiveness.

[0118] Specifically, the angle α between the extension directions of the two bristles 22 can be 120°, 110°, 100°, 90°, 80°, or other angles. By properly setting the angle α between the extension directions of the two bristles 22, when the base 1 is in the installed position, the two bristles 22 can be relatively fully located within the edge projection area of ​​the mobile host 9. At the same time, the two bristles 22 have a large radiation range, thereby ensuring a good auxiliary cleaning effect when the base 1 is in the working position.

[0119] As shown in Figures 6, 10, and 11, in some possible embodiments provided by the present disclosure, the projection of the side brush arm 21 on the horizontal plane is an involute. An involute refers to the trajectory of a point K on a straight line when it is purely rolling on a circle. In this embodiment, the side brush arm 21 is spiral-shaped, and the projection of the spiral-shaped side brush arm 21 on the horizontal plane is an involute. This can be understood as the following: the base 1 is cylindrical, the axial direction of the base 1 can be considered perpendicular to the horizontal plane, and the side brush arm 21 is distributed in a spiral shape along the axial direction of the base 1. The projection of the side brush arm 21 on the horizontal plane coincides with the portion of the trajectory of the point K on the straight line when it is purely rolling on the cylindrical base 1 that connects to the base 1. Pure rolling refers to rolling in which the point of contact between a rigid body and a plane is relatively stationary at the moment of contact, without any relative sliding, i.e., rolling with zero relative velocity. When the plane is a fixed plane, the point of contact is the instantaneous center of velocity of the two objects.

[0120] Among them, the horizontal plane can be regarded as perpendicular to the rotation axis of the base 1. Since the side brush arm 21 is spiral, the projection of the side brush arm 21 on the horizontal plane is a spiral involute. In this way, during the rotation of the base 1, hair, wires and other debris wrapped around the side brush arm 21 will move along the rotating, spiral side brush arm 21 and will be tightly wrapped around the side brush arm 21. During the continued rotation of the base 1, the force of the debris wrapping around the side brush arm 21 will increase. The side brush arm 21 is set as an elastic part. When the wrapping force of the debris on the side brush arm 21 reaches the limit value that the elastic side brush arm 21 can withstand, the elastic deformation of the side brush arm 21 will bounce off the debris wrapped around the side brush arm 21, reducing the possibility of entanglement of hair, wires and other debris, thereby reducing the frequency of users cleaning the side brush assembly 10, and extending the replacement cycle of the side brush assembly 10, reducing the use cost, and improving the user experience.

[0121] As shown in Figure 10, in some possible embodiments provided by the present disclosure, the two side brush arms 21 are located on the same side of the base 1 through the center line of the rotating shaft of the base 1. This arrangement can ensure that the two side brush arms 21 are relatively concentratedly arranged on the peripheral side of the base 1, and the peripheral side of the base 1 has a larger range without side brush arms 21 to ensure that the original structure of the cleaning equipment is not changed. The side brush assembly 10 is connected to the drive assembly. When the base 1 is in the installation position, the two bristles 22 can be effectively located within the edge projection area of ​​the mobile host 9, and when the base 1 is in the working position, some of the bristles 22 can be located outside the edge projection area of ​​the mobile host 9.

[0122] As shown in FIG10 , in some possible embodiments provided by the present disclosure, the angle between the extension direction of the bristles 22 and the extension direction of the connected side brush arm 21 relative to the base 1 is not greater than 120°, that is, the angle between the extension direction of the bristles 22 and the extension direction of the connected side brush arm 21 relative to the base 1 is less than or equal to 120°, wherein the angle between the extension direction of the bristles 22 and the extension direction of the connected side brush arm 21 relative to the base 1 can be shown as angle β in FIG10 , that is, β is less than or equal to 120°. Specifically, β can be 120°, 110°, 100°, 90°, 80°, or other angles.

[0123] This arrangement can ensure that the two side brush arms 21 and the two bristles 22 are relatively concentratedly arranged on a part of the circumference of the base 1, while the side brush arms 21 are not arranged on the other part of the circumference of the base 1, so that the base 1 can be rotated to different positions relative to the mobile host 9, and the two bristles 22 can be effectively located within the edge projection area of ​​the mobile host 9 to place the base 1 in the installation position, or, part of the bristles 22 can be located outside the edge projection area of ​​the mobile host 9 to place the base 1 in the working position. Therefore, the side brush assembly 10 provided in this embodiment can be connected to the drive assembly without changing the original structure of the cleaning equipment, and the installation position of the base 1 can be reasonably limited by the first installation indicator 12 and the second installation indicator, so as to ensure that the bristles 22 are located within the edge projection area of ​​the mobile host 9 when the base 1 is in the installation position, and the base 1 is driven to rotate by the drive assembly to realize the switching of the installation position and the working position of the base 1. The operation is simple and easy to implement.

[0124] As shown in Figures 11 and 12, in some possible embodiments provided by the present disclosure, the side brush arm 21 includes a first end 214 connected to the bristles 22. A blocking protrusion 32 is provided at the bottom of the first end 214. The bristles 22 are arranged obliquely downward from the first end 214 relative to the blocking protrusion 32. This ensures that the bristles 22 exert sufficient interference force on the surface being cleaned, ensuring a good cleaning effect. Furthermore, this arrangement places the blocking protrusion 32 below the portion where the bristles 22 connect to the first end 214, preventing debris from moving or scurrying from below the first end 214 along the side brush arm 21 toward the base 1. In other words, the blocking protrusion 32 restricts the movement of debris, such as hair and thread, along the side brush arm 21 from the first end 214 toward the base 1, thereby reducing the likelihood of debris, such as hair and thread, approaching the base 1 and entering the drive assembly through the side brush arm 21 and base 1, potentially causing failure. This, in turn, helps extend the service life and reliability of the drive assembly.

[0125] Specifically, the drive assembly can be a motor, and the base 1 is connected to the output shaft of the motor. If hair, thread, or other debris is entangled in the side brush assembly 10, and if the debris winds upward along the circumferential sidewalls of the base 1 and becomes entangled on the output shaft, the output shaft may become stuck, thereby affecting the reliability of the motor. The present disclosure, through the provision of the blocking protrusion 32, can significantly reduce the occurrence of this problem, thereby extending the service life of the motor.

[0126] As shown in Figures 11 and 12, in some possible embodiments provided by the present disclosure, the first end portion 214 includes a first portion 2141 and a second portion 2142 located above the first portion 2141. The first portion 2141 is provided with a blocking protrusion 32 and is connected to the bristles 22. The second portion 2142 protrudes from the first portion 2141 along the extension direction of the side brush arm 21. The up and down directions are indicated by arrows Z in Figure 12.

[0127] That is, the second portion 2142 is located above the bristles 22, and the blocking protrusion 32 is located below the bristles 22. Thus, the second portion 2142 forms a rib-like structure that can prevent debris from moving along the bristles 22 toward the side brush arm 21 from above the bristles 22. Therefore, the second portion 2142 and the blocking protrusion 32 cooperate to simultaneously prevent debris from moving along the bristles 22 toward the side brush arm 21 from above and below the bristles 22 at the first end portion 214. This further limits the possibility of debris such as hair and thread moving along the bristles 22 through the first end portion 214 to the side brush arm 21, thereby reducing the possibility of the side brush arm 21 becoming entangled by hair and thread debris. This, in turn, reduces the possibility of hair and thread debris approaching the base 1 and the possibility of debris passing through the side brush arm 21 and the base 1 and entering the drive assembly, thereby causing a malfunction of the drive assembly. This, in turn, helps extend the service life of the drive assembly and improves its reliability.

[0128] As shown in Figures 11 and 12, in some possible embodiments provided by the present disclosure, the second portion 2142 is arranged upwardly and tilted relative to the first portion 2141, away from the base 1. In other words, the gap between the second portion 2142 and the bristles 22 gradually increases from away from the base 1 to closer to the base 1. This arrangement guides the movement of debris along the bristles 22, allowing the debris to be smoothly accommodated in the gap between the second portion 2142 and the bristles 22. This reduces the possibility of debris moving from above the second portion 2142 to the side brush arm 21, and effectively prevents hair and thread-like debris from being entangled in the side brush arm 21.

[0129] As shown in Figure 9, in some possible embodiments provided by the present disclosure, the side brush arm 21 includes a second end portion 215 connected to the base 1, and the base 1 is injection-molded and wrapped around the outside of the second end portion 215. That is, the base 1 and the side brush arm 21 can be processed by the injection molding process, thereby ensuring the reliability of the connection between the side brush arm 21 and the base 1, and at the same time, it is easy to process and easy to produce.

[0130] Furthermore, the side brush arm 21 and the base 1 are both made of plastic, which has low cost, is easy to shape, convenient to process, and suitable for promotion and application.

[0131] The hardness of the base 1 is greater than that of the side brush arm 21. For example, if the base 1 is made of hard plastic and the side brush arm 21 is made of soft plastic, the base 1 can be ensured to have sufficient hardness and strength, and the side brush arm 21 can be ensured to have sufficient strength and elasticity. Specifically, the elasticity of the side brush arm 21 is greater than that of the base 1.

[0132] As shown in Figure 10, in some possible embodiments provided by the present disclosure, the side brush arm 21 includes a first arm body 211, a second arm body 212, and a third arm body 213 arranged in sequence along the direction from the base 1 to the bristles 22, wherein the first arm body 211, the second arm body 212, and the third arm body 213 gradually become thinner.

[0133] Among them, the first arm body 211, the second arm body 212, and the third arm body 213 gradually become thinner, which can be understood as the width of the projection of the first arm body 211, the second arm body 212, and the third arm body 213 in the horizontal plane gradually becoming smaller, or, it can be understood as the size of the first arm body 211, the second arm body 212, and the third arm body 213 in the vertical direction gradually becoming smaller, or, it can be understood as the width of the projection of the first arm body 211, the second arm body 212, and the third arm body 213 in the horizontal plane gradually becoming smaller, and at the same time, the size of the first arm body 211, the second arm body 212, and the third arm body 213 in the vertical direction gradually becoming smaller. Specifically, the width of the projection of the side brush arm 21 in the horizontal plane can be shown as the distance D in Figure 10, and the size of the side brush arm 21 along the vertical direction can be the size of the side brush arm 21 along the Z-axis direction.

[0134] This arrangement can ensure that the first arm 211 connected to the base 1 has sufficient strength, so that the base 1 and the side brush arm 21 can be reliably connected. At the same time, it can ensure that the third arm 213 connected to the bristles 22 has sufficient elasticity, so that the bristles 22 have sufficient contact force on the surface to be cleaned, thereby ensuring a good cleaning effect. The second arm 212 located between the first arm 211 and the third arm 213 can achieve a transitional connection between the first arm 211 and the third arm 213, so that from the first arm 211 to the third arm 213, the strength of the side brush arm 21 gradually decreases and the elasticity of the side brush arm 21 gradually increases, thereby ensuring that the side brush arm 21 has good strength and elasticity. It is understandable that when the base 1 rotates, the starting point of the deformation position of the side brush arm 21 can be located at the second arm 212 of the side brush arm 21.

[0135] As shown in Figure 13, according to an embodiment of the present disclosure, a cleaning assembly is proposed, including: a transmission part 6, which is used for transmission connection to the drive assembly; a side brush assembly 10, which can generate a rotational motion relative to the transmission part 6 so that the side brush assembly 10 can be separated or fixed to the transmission part 6.

[0136] The cleaning assembly provided by the embodiment of the present disclosure includes a transmission part 6 and a side brush assembly 10, wherein the side brush assembly 10 is detachably screwed to the transmission part 6 so that the side brush assembly 10 can be separated or fixed to the transmission part 6. In actual application, the transmission part 6 and the side brush assembly 10 can be disassembled and assembled by tightening or loosening them together, which can improve the convenience of disassembly and assembly between the side brush assembly 10 and the transmission part 6, facilitate the user to apply force during disassembly and assembly, reduce the difficulty of operation for the user, improve the convenience of disassembly and cleaning of the side brush assembly 10, and improve the user experience. In addition, the screwing connection between the transmission part 6 and the side brush assembly 10 can also reduce the deformation requirements of the mating parts of the transmission part 6 and the side brush assembly 10 during disassembly and assembly, thereby reducing the structural deformation of the transmission part 6 and the side brush assembly 10 during disassembly and assembly, reducing the risk of structural damage to the transmission part 6 and the side brush assembly 10 during disassembly and assembly, and helping to extend the service life of the transmission part 6 and the side brush assembly 10.

[0137] In actual application, the aforementioned transmission part 6 can be connected to the driving component, so that it can receive the power output by the driving component. Accordingly, when the side brush assembly 10 is screwed into the transmission part 6, the transmission part 6 can further drive the side brush assembly 10 to move, so that the side brush assembly 10 performs a cleaning action.

[0138] It is understood that in actual applications, the cleaning assembly provided by the embodiments of the present disclosure can be provided in a cleaning device or used as a component of a cleaning device, and the aforementioned cleaning device may be, but is not limited to, a sweeping robot, a mopping robot, an all-in-one sweeper and mop machine, etc. The aforementioned side brush assembly 10 may include a cleaning body, and the aforementioned cleaning body may include, but is not limited to, a brush body, a mop, etc.

[0139] It can be understood that in actual applications, the transmission form between the aforementioned transmission part 6 and the drive assembly can be but not limited to belt transmission, gear transmission, connecting rod transmission, chain transmission, etc. Accordingly, the transmission part 6 can include transmission elements that match the transmission form, such as pulleys and transmission belts, gears, transmission rods, chains and sprockets, etc.; the transmission level of the transmission part 6 can be greater than or equal to 1, and the aforementioned side brush assembly 10 can be detachably screwed with the transmission part 6 of the output stage; the specific transmission form and transmission level can be set according to actual needs, and no excessive restrictions are made here.

[0140] It should be noted that the transmission portion 6 and the side brush assembly 10 may have a connection structure for screwing together. For example, the transmission portion 6 has a first connection structure, and the side brush assembly 10 has a second connection structure that can be screwed together with the first connection structure. For example, one of the first connection structure and the second connection structure may be a screw buckle 6211, and the other may be a screwing groove 53, so that the transmission portion 6 and the side brush assembly 10 can be screwed together by screwing together the buckle groove; or one of the first connection structure and the second connection structure may be an external thread, and the other may be an internal thread, so that the transmission portion 6 and the side brush assembly 10 can be screwed together by screwing together the threads. The specific forms of the aforementioned first connection structure and the aforementioned second connection structure can be selected in combination with actual needs and are not excessively limited here; it can be understood that, compared with the way the side brush assembly 10 is disassembled and assembled using a snap-on method, the present disclosure provides a side brush assembly 10 that is detachably screwed to the aforementioned transmission part 6, which can reduce the deformation requirements of the side brush assembly 10 and the transmission part 6 during the disassembly and assembly process, thereby reducing the risk of structural damage to the side brush assembly 10 and the transmission part 6, facilitating multiple disassembly and assembly between the side brush assembly 10 and the transmission part 6, and also making it easier for the user to apply force during the disassembly and assembly process, thereby improving the convenience of the disassembly and assembly operation.

[0141] It can be understood that in the process of screwing together and disassembling the aforementioned transmission part 6 and the aforementioned side brush assembly 10, a relative screwing movement will be generated between the aforementioned transmission part 6 and the side brush assembly 10. The aforementioned screwing movement can be decomposed into a relative translation between the aforementioned transmission part 6 and the side brush assembly 10 along the aforementioned screwing axis, and a relative rotation around the aforementioned screwing axis. Accordingly, the side brush assembly 10 can be tightened or loosened relative to the transmission part 6 through the screwing movement, thereby being fixed or separated from the transmission part 6. Moreover, in the process of screwing together the aforementioned transmission part 6 and the aforementioned side brush assembly 10, the aforementioned transmission part 6 and the side brush assembly 10 will approach each other along the screwing axis, that is, the structural overlap in the screwing axis will increase, until the transmission part 6 and the side brush assembly 10 are tightened. When the transmission part 6 and the side brush assembly 10 are tightened, the displacement of the transmission part 6 and the side brush assembly 10 along the screwing axis will be restricted, thereby ensuring the connection reliability between the transmission part 6 and the side brush assembly 10; accordingly, in the process of disassembling the aforementioned transmission part 6 and the aforementioned side brush assembly 10, the aforementioned transmission part 6 and the side brush assembly 10 will move away from each other along the screwing axis, that is, the structural overlap in the screwing axis will decrease, until the structure is separated.

[0142] It can be understood that the aforementioned screwing axial direction is also the axial direction of the screwing movement. For example, the extension direction of the dot-dashed line F in FIG15 can be used to schematically represent the aforementioned screwing axial direction.

[0143] As shown in FIG. 14 and FIG. 15 , in some examples, the cleaning assembly further includes a force-applying portion 7 for applying a force to the transmission portion 6 and the side brush assembly 10 along the axial direction of the screwing.

[0144] In this technical solution, the aforementioned force-applying portion 7 is used to apply a force to the transmission portion 6 and the side brush assembly 10 along the axis of screwing, so that in the process of screwing or disassembling the transmission portion 6 and the side brush assembly 10, the transmission portion 6 and the side brush assembly 10 can be moved closer to or farther away from each other along the axis of screwing under the action of the aforementioned force, thereby assisting the user in applying force during the disassembly and assembly process, which is beneficial to improving the disassembly and assembly efficiency. When the transmission portion 6 and the side brush assembly 10 are in a tightened state, a greater contact force can be generated between the transmission portion 6 and the side brush assembly 10 along the axis of screwing under the action of the aforementioned force, thereby reducing the risk of loosening between the transmission portion 6 and the side brush assembly 10, enhancing the connection reliability between the transmission element and the side brush assembly 10, and providing reliable guarantee for the side brush assembly 10 to smoothly perform the cleaning action.

[0145] It can be understood that the force applied by the aforementioned force-applying portion 7 to the transmission portion 6 and the side brush assembly 10 can promote the relative translation between the transmission portion 6 and the side brush assembly 10 along the aforementioned screwing axis during the screwing or disassembly process, thereby facilitating the user to apply force and helping to improve the efficiency of assembly and disassembly. When the transmission portion 6 and the side brush assembly 10 are in a tightened state, the transmission portion 6 and the side brush assembly 10 can generate a greater contact force along the screwing axis under the action of the aforementioned force, thereby reducing the risk of loosening between the transmission portion 6 and the side brush assembly 10.

[0146] It can be understood that the aforementioned force-applying portion 7 can apply a force on the transmission portion 6 along the axis of screwing, away from the side brush assembly 10, and apply a force on the side brush assembly 10 along the axis of screwing, away from the transmission portion 6, thereby improving the disassembly efficiency of the aforementioned transmission portion 6 and the aforementioned side brush assembly 10; or, the aforementioned force-applying portion 7 can apply a force on the transmission portion 6 along the axis of screwing, toward the side brush assembly 10, and apply a force on the side brush assembly 10 along the axis of screwing, thereby improving the screwing efficiency of the aforementioned transmission portion 6 and the aforementioned side brush assembly 10.

[0147] It can be understood that the direction of the aforementioned force has a high degree of parallelism with the aforementioned screwing axis, that is, the direction of the aforementioned force and the aforementioned screwing axis can be parallel to each other or intersect with each other. When the direction of the aforementioned force intersects with the aforementioned screwing axis, the component of the aforementioned force in the aforementioned screwing axis is greater than or equal to the component of the aforementioned force in the direction orthogonal to the aforementioned screwing axis.

[0148] As shown in Figures 14 and 15, in some examples, the force-applying part 7 includes: an elastic telescopic component 71, one of the transmission part 6 and the side brush assembly 10 is connected to one end of the elastic telescopic component 71, and the other is detachably connected to the other end of the elastic telescopic component 71, and the elastic telescopic component 71 is arranged along the axial direction of the screwing; wherein, when the side brush assembly 10 is screwed onto the transmission part 6, the elastic telescopic component 71 applies a force on the transmission part 6 that is away from the side brush assembly 10, and applies a force on the side brush assembly 10 that is away from the transmission part 6.

[0149] In this technical solution, the aforementioned force-applying part 7 may include an elastic telescopic component 71. When the side brush assembly 10 is screwed into the transmission part 6, the elastic telescopic component 71 can apply a force on the transmission part 6 that is away from the side brush assembly 10, and can apply a force on the side brush assembly 10 that is away from the transmission part 6. Therefore, based on the aforementioned arrangement, on the one hand, in the process of disassembling the transmission part 6 and the side brush assembly 10, the transmission part 6 and the side brush assembly 10 can be facilitated to move away from each other along the axis of screwing under the action of the elastic telescopic component 71, thereby assisting the user in applying force during the disassembly process, which is beneficial to improving the disassembly efficiency; on the other hand, when the transmission part 6 and the side brush assembly 10 are in a tightened state, a greater contact force can be generated between the transmission part 6 and the side brush assembly 10 along the axis of screwing under the action of the elastic telescopic component 71, thereby reducing the risk of loosening between the transmission part 6 and the side brush assembly 10, enhancing the structural reliability between the transmission element and the side brush assembly 10, and providing reliable guarantee for the side brush assembly 10 to perform the cleaning action smoothly.

[0150] The two ends of the aforementioned elastic telescopic component 71 can be respectively connected to the aforementioned transmission part 6 and the aforementioned side brush assembly 10, wherein the elastic telescopic component 71 and the transmission part 6 or the side brush assembly 10 are in a detachable connection relationship, so that the structural constraints brought by the elastic telescopic component 71 can be reduced during the disassembly of the transmission part 6 and the side brush assembly 10, and the disassembly between the transmission part 6 and the side brush assembly 10 is further facilitated; the aforementioned elastic telescopic component 71 can be arranged along the aforementioned screw-on axis, that is, the telescopic direction of the aforementioned elastic telescopic component 71 can be set to maintain a high degree of parallelism with the aforementioned screw-on axis, thereby facilitating the elastic telescopic component 71 to apply the aforementioned force to the transmission part 6 and the side brush assembly 10, and the elastic telescopic component 71, based on its telescopic performance, can also adapt to the relative position changes of the transmission part 6 and the side brush assembly 10 on the screw-on axis through elastic deformation during the screw-on and disassembly of the aforementioned transmission part 6 and the aforementioned side brush assembly 10, which is beneficial to improving the structural flexibility and reliability of the cleaning component.

[0151] It can be understood that one of the aforementioned transmission part 6 and side brush assembly 10 is connected to one end of the elastic telescopic assembly 71, and the other is detachably connected to the other end of the elastic telescopic assembly 71, that is, the transmission part 6 can be fixedly connected to one end of the elastic telescopic assembly 71, and the side brush assembly 10 can be detachably connected to the other end of the elastic telescopic assembly 71, so that when the side brush assembly 10 is separated from the transmission part 6, the elastic telescopic assembly 71 can remain on the transmission part 6, which is convenient for independent cleaning of the side brush assembly 10; or, the transmission part 6 can be detachably connected to one end of the elastic telescopic assembly 71, and the side brush assembly 10 is fixedly connected to the other end of the elastic telescopic assembly 71, so that when the side brush assembly 10 is separated from the transmission part 6, the elastic telescopic assembly 71 can be separated from the transmission part 6 at the same time, which is convenient for maintenance of the elastic telescopic assembly 71.

[0152] It can be understood that during the process of screwing the transmission part 6 and the side brush assembly 10 together, the user can overcome the telescopic force of the elastic telescopic rod by squeezing the transmission part 6 and the side brush assembly 10 along the screwing axis, so that the transmission part 6 and the side brush assembly 10 are close to each other along the screwing axis, and then the transmission part 6 and the side brush assembly 10 are screwed together.

[0153] As shown in Figures 14 and 15, in some examples, the elastic telescopic assembly 71 includes: a mounting seat 711, which is arranged on the transmission part 6; a support member 712, having a first support end 7121 and a second support end 7122, the first support end 7121 is arranged toward the mounting seat 711, and the second support end 7122 is detachably connected to the side brush assembly 10; a spring 713, which is connected between the first support end 7121 and the mounting seat 711, and the spring 713 is arranged along the screw axis.

[0154] In this technical solution, the aforementioned elastic telescopic component 71 may include a mounting seat 711, a support member 712 and a spring 713, wherein the spring 713 is connected between the mounting seat 711 and the support member 712, so that the spring 713 can apply elastic force to the mounting seat 711 and the support member 712; the spring 713 is arranged along the aforementioned screw-on axis, the mounting seat 711 is set in the transmission part 6, the first support end 7121 of the support member 712 faces the mounting seat 711, and the second support end 7122 is used to be detachably connected to the side brush assembly 10. Based on the above-mentioned arrangement, on the one hand, when the side brush assembly 10 is separated from the transmission part 6, the elastic telescopic assembly 71 can be retained in the transmission part 6, so as to facilitate independent cleaning of the side brush assembly 10; on the other hand, in the process of screwing in and disassembling the transmission part 6 and the side brush assembly 10, when the spring 713 is in a compressed state, the elastic telescopic assembly 71 can apply a force away from the transmission part 6 to the side brush assembly 10 through the aforementioned second support end 7122, and at the same time, based on the connection relationship between the aforementioned mounting seat 711 and the transmission part 6, a force away from the side brush assembly 10 can be applied to the transmission part 6. Then, the force generated by the elastic telescopic assembly 71 on the transmission part 6 and the side brush assembly 10 can assist the user in disassembling the force, facilitate disassembly between the transmission part 6 and the side brush assembly 10, and can increase the mutual contact force between the transmission part 6 and the side brush assembly 10 when the transmission part 6 and the side brush assembly 10 are tightened, thereby enhancing the connection reliability between the transmission part 6 and the side brush assembly 10.

[0155] As shown in FIG14 and FIG15 , in some examples, the transmission part 6 is provided with a mounting groove 612, the mounting seat 711 is disposed in the mounting groove 612, the support member 712 is movably disposed through the transmission part 6, and the first support end 7121 is movably disposed in the mounting groove 612; and / or

[0156] The side brush assembly 10 defines a limiting groove 52 , and the second support end 7122 is detachably inserted into the limiting groove 52 .

[0157] In this technical solution, the transmission part 6 can use the mounting groove 612 to provide a mounting location and structural protection for the force-applying part 7, thereby reducing the exposure of the force-applying part 7, improving the reliability and stability of the force-applying part 7, and reducing the probability of damage to the force-applying part 7. The first support end 7121 is movably disposed within the mounting groove 612, and the second support end 7122 can extend or retract into the transmission part 6. When the second support end 7122 extends out of the transmission part 6, it can facilitate the docking of the elastic expansion assembly 71 with the cleaning assembly.

[0158] In this technical solution, the side brush assembly 10 can dock with the second support end 7122 of the support member 712 via the retaining groove 52. When the side brush assembly 10 is screwed onto the transmission unit 6, the second support end 7122 is inserted into the retaining groove 52, and the spring 713 is in a compressed state. This arrangement ensures a stable connection between the side brush assembly 10 and the support member 712 when docked. Furthermore, it facilitates separation of the second telescopic end from the side brush assembly 10 during disassembly of the transmission unit 6 and the side brush assembly 10, facilitating assembly and disassembly of the elastic telescopic assembly 71 from the side brush assembly 10.

[0159] It can be understood that, in this technical solution, the cleaning component can have at least one of the aforementioned mounting groove 612 and the aforementioned limiting groove 52 .

[0160] In some examples, the force-applying part 7 includes: a first magnetic part, which is arranged on the transmission part 6; a second magnetic part, which is arranged on the side brush assembly 10, the first magnetic part and the second magnetic part are arranged opposite to each other along the rotating axis, and the second magnetic part is used to apply magnetic force to the first magnetic part.

[0161] In this technical solution, the aforementioned force-applying part 7 may include a first magnetic part and a second magnetic part, and the first magnetic part and the second magnetic part are respectively arranged on the transmission part 6 and the side brush assembly 10, and when the side brush assembly 10 is screwed into the transmission part 6, the first magnetic part and the second magnetic part are arranged relative to each other along the aforementioned screwing axis. Based on the above-mentioned arrangement, on the one hand, when the transmission part 6 and the side brush assembly 10 are tightened, the magnetic force generated between the first magnetic part and the second magnetic part is conducive to improving the mutual contact force between the transmission part 6 and the side brush assembly 10, enhancing the connection reliability between the transmission part 6 and the side brush assembly 10, and reducing the risk of the side brush assembly 10 loosening; on the other hand, when the magnetic force between the first magnetic part and the second magnetic part is in the form of repulsive force, it is convenient for the transmission part 6 and the side brush assembly 10 to move away from each other along the axis of the screwing, thereby assisting the user to apply force during the disassembly process, which is conducive to improving the disassembly efficiency, or, when the magnetic force between the first magnetic part and the second magnetic part is in the form of attractive force, it is convenient for the transmission part 6 and the side brush assembly 10 to move closer to each other along the axis of the screwing, thereby assisting the user to apply force during the assembly process, which is conducive to improving the assembly efficiency; on the other hand, there is no need for structural connection between the first magnetic part and the second magnetic part, which is conducive to reducing the structural damage and operating resistance of the cleaning assembly during the disassembly and assembly process, and is conducive to improving the structural compactness of the cleaning assembly.

[0162] In some examples, one of the first magnetic member and the second magnetic member is a permanent magnet, and the other is made of a magnetic material; or

[0163] The first magnetic member and the second magnetic member are both permanent magnets. The first magnetic member has a first magnetic pole, and the second magnetic member has a second magnetic pole. The first magnetic pole and the second magnetic pole are arranged opposite to each other along the rotating axis, and the first magnetic pole and the second magnetic pole are poles of the same name.

[0164] In this technical solution, one of the first magnetic member and the second magnetic member can be a permanent magnet, and the other can be made of a magnetic material, that is, the first magnetic member can be a permanent magnet and the second magnetic member can be made of a magnetic material, or the first magnetic member can be made of a magnetic material and the second magnetic member can be a permanent magnet. Based on the above arrangement, the magnetic force between the first magnetic member and the second magnetic member can be in the form of an attractive force, so that during the process of assembling the transmission part 6 and the side brush assembly 10, the transmission part 6 and the side brush assembly 10 can be easily brought closer to each other along the screwing axis, thereby assisting the user in applying force during the assembly process, which is conducive to improving assembly efficiency.

[0165] Alternatively, the first magnetic member and the second magnetic member can be both permanent magnets, and the like poles of the first magnetic member and the second magnetic member can be arranged relative to each other along the axis of the rotation. Based on the above arrangement, the magnetic force between the first magnetic member and the second magnetic member can be in the form of a repulsive force, so that in the process of disassembling the transmission part 6 and the side brush assembly 10, the transmission part 6 and the side brush assembly 10 can be facilitated to move away from each other along the axis of the rotation, thereby assisting the user in applying force during the disassembly process, which is conducive to improving the disassembly efficiency.

[0166] It can be understood that the aforementioned first magnetic pole and the second magnetic pole are poles with the same name, which means that the first magnetic pole and the second magnetic pole are both N poles or both S poles.

[0167] It is understandable that the aforementioned permanent magnets may be, but are not limited to, alloy permanent magnets or ferrite permanent magnets, etc.; the aforementioned magnetic materials may be, but are not limited to, iron, cobalt, nickel, etc.

[0168] In some examples, the transmission part 6 has a first accommodating space, which is located in the axial area of ​​the transmission part 6, the side brush assembly 10 has a second accommodating space, which is located in the axial area of ​​the transmission part 6, and the first magnetic part and the second magnetic part are respectively arranged in the first accommodating space and the second accommodating space.

[0169] In this technical solution, the transmission part 6 and the side brush assembly 10 can respectively utilize the first accommodating space and the second accommodating space to accommodate the first magnetic part and the second magnetic part respectively, and provide structural protection for the first magnetic part and the second magnetic part, thereby reducing the risk of damage and contamination of the first magnetic part and the second magnetic part, extending the service life of the first magnetic part and the second magnetic part, and reducing the maintenance cost of the first magnetic part and the second magnetic part; and, the first accommodating space and the second accommodating space can be set to be located in the axial area of ​​the transmission part 6 and the side brush assembly 10 respectively, so that during the screwing or disassembly process, it can be ensured that there is a good position correspondence between the first magnetic part and the second magnetic part, providing a guarantee for generating a stable magnetic force between the first magnetic part and the second magnetic part.

[0170] It can be understood that the axial area of ​​the aforementioned transmission part 6, that is, the transmission part 6 corresponds to the area of ​​the dotted line F in Figure 15; similarly, the axial area of ​​the aforementioned side brush assembly 10, that is, the transmission part 6, corresponds to the area of ​​the dotted line F in Figure 15.

[0171] As shown in Figures 13 to 19, in some examples, the transmission part 6 includes a transmission member 61 and a connecting member 62 that are connected to each other, and the transmission member 61 is used to transmit the connection to the drive assembly; one of the side brush assembly 10 and the connecting member 62 is formed with a rotary buckle 6211, and the other is formed with a screw-on groove 53, and the rotary buckle 6211 is detachably screwed into the screw-on groove 53.

[0172] In this technical solution, the transmission portion 6 may include a transmission member 61 and a connecting member 62. The transmission member 61 is connected to the connecting member 62. In actual use, the transmission portion 6 can be transmission-connected to the drive assembly, thereby receiving power output by the drive assembly and driving the connecting member 62 to move synchronously. One of the side brush assembly 10 and the connecting member 62 is formed with a screw-lock 6211, and the other is formed with a screw-lock groove 53. The screw-lock 6211 is detachably screwed into the screw-lock groove 53. In other words, the transmission portion 6 can be screwed together with the side brush assembly 10 via the connecting member 62. On the one hand, the transmission portion 6 can receive power through the transmission member 61 and connect to the side brush assembly 10 through the connecting member 62 to transmit power, thereby enhancing the smoothness of the transmission process. On the other hand, the transmission portion 6 and the side brush assembly 10 can be screwed together via the screw-lock groove, which can reduce the design difficulty of the transmission portion 6 and the side brush assembly 10, ensure the convenience of the screw-lock operation, further reduce the user's operating difficulty, and improve the user experience of the product.

[0173] It should be noted that one of the side brush assembly 10 and the connecting member 62 is formed with a rotary buckle 6211, and the other is formed with a screw-on groove 53. The side brush assembly 10 can be formed with a rotary buckle 6211, and the connecting member 62 is formed with a screw-on groove 53, thereby reducing the groove structure of the side brush assembly 10, which is beneficial to reducing the chance of dirt and accumulation of dirt in the side brush assembly 10, thereby reducing the cleaning and maintenance workload of the side brush assembly 10, and is beneficial to improving the structural reliability of the side brush assembly 10; or as shown in Figures 14 and 15, the side brush assembly 10 can be formed with a rotary buckle 6211, and the connecting member 62 is formed with a screw-on groove 53. One of the brush assembly 10 and the connecting member 62 is formed with a rotary buckle 6211, and the other is formed with a screw-on groove 53. The side brush assembly 10 can be formed with the screw-on groove 53, and the connecting member 62 can be formed with the rotary buckle 6211, so as to ensure the structural strength of the transmission part 6, enhance the stability and reliability of the transmission process, and facilitate the side brush assembly 10 to smoothly perform the cleaning action. In the process of cleaning the side brush assembly 10, if there is dirt in the screw-on groove 53, it is also easy for the user to find and clean it in time, which is beneficial to the maintenance of the cleaning assembly.

[0174] Alternatively, in this technical solution, one of the side brush assembly 10 and the connector 62 can be formed with an internal thread, and the other can be formed with an external thread, that is, the side brush assembly 10 can be formed with an internal thread and the connector 62 can be formed with an external thread, or the side brush assembly 10 can be formed with an external thread and the connector 62 can be formed with an internal thread, so that the connector 62 and the side brush assembly 10 can be screwed together by threaded screwing, which is beneficial to ensure the convenience of disassembly and assembly between the connector 62 and the side brush assembly 10 while improving the connection reliability of the connector 62 and the side brush assembly 10 in the assembled state, and providing a guarantee for the side brush assembly 10 to perform the cleaning action smoothly.

[0175] It can be understood that the aforementioned side brush assembly 10 can have a cleaning end and a connecting end, the aforementioned cleaning end is used to clean the object to be cleaned during the cleaning process, and the aforementioned connecting end is away from the aforementioned cleaning end; in actual application, the aforementioned knob 6211 can be formed at the aforementioned connecting end or the end of the aforementioned connecting member 62 away from the transmission member 61, and accordingly, the aforementioned screw-on groove 53 can be formed at the aforementioned connecting end or the end of the aforementioned connecting member 62 away from the transmission member 61.

[0176] It can be understood that the aforementioned screw-on groove 53 can be continuously extended in the form of a spiral line, which is conducive to ensuring the connection reliability between the screw buckle 6211 and the screw-on groove 53 when tightening, reducing the risk of loosening, and based on the setting of the aforementioned connecting member 62, it is convenient for the user to apply force during the tightening or loosening process, and further ensure the connection reliability when tightening; or, as shown in Figures 18 and 19, the aforementioned screw-on groove 53 can have at least two groove sections with different extension directions. Taking the aforementioned screw-on groove 53 opened in the side brush assembly 10 as an example, the aforementioned at least two groove sections with different extension directions may include at least one guide groove section extending from the aforementioned connecting end to the aforementioned cleaning end, and at least one rotating groove section extending circumferentially along the side brush assembly 10. The aforementioned guide groove section may have a notch of the screw-on groove 53 to facilitate the insertion of the rotary buckle 6211. Accordingly, in the process of the rotary buckle 6211 moving in the aforementioned guide groove section, the relative position change along the aforementioned screw-on axis can be generated between the side brush assembly 10 and the connecting member 62. When the aforementioned rotary buckle 6211 moves in the aforementioned rotating groove section, relative rotation can be generated between the side brush assembly 10 and the connecting member 62, thereby constraining the relative movement of the side brush assembly 10 and the connecting member 62 along the aforementioned screw-on axis, thereby realizing the screwing between the side brush assembly 10 and the connecting member 62.

[0177] It can be understood that the aforementioned side brush assembly 10 and / or the aforementioned transmission part 6 can be formed with a rotation direction mark, which is used to indicate the direction of the loosening operation and the direction of the tightening operation, thereby further facilitating the user to disassemble and assemble the transmission part 6 and the side brush assembly 10, thereby improving the user experience of the product.

[0178] It is understandable that the aforementioned rotary buckle 6211 can be a rib, a bump, etc. protruding from the connecting member 62. The specific shape of the aforementioned rotary buckle 6211 can be specifically set according to actual needs and can be suitable for screwing into the screwing groove 53. No further restrictions are made here.

[0179] As shown in Figures 18 and 19, in some examples, the screw-on groove 53 includes: a first groove section 531, the notch of the screw-on groove 53 is located at one end of the first groove section 531; a second groove section 532, which is connected to the other end of the first groove section 531, and the extension direction of the second groove section 532 is different from the extension direction of the first groove section 531. When the knob 6211 moves into the second groove section 532, the side brush assembly 10 rotates relative to the connecting member 62; a third groove section 533, which is connected to the second groove section 532. The third groove section 533 is located on the side of the second groove section 532 close to the aforementioned groove opening. When the knob 6211 is located in the third groove section 533, the knob 6211 abuts against the groove wall of the third groove section 533 to limit the side brush assembly 10 from moving in a direction away from the connecting member 62; wherein, when the knob 6211 is located in the second groove section 532, the force-applying part 7 applies a force on the transmission part 6 that is away from the side brush assembly 10, and applies a force on the side brush assembly 10 that is away from the transmission part 6.

[0180] In this technical solution, the aforementioned screw-on groove 53 may include a first groove section 531, a second groove section 532 and a third groove section 533 which are connected in sequence, and the second groove section 532 is located between the first groove section 531 and the third groove section 533, wherein the notch of the screw-on groove 53 is located at one end of the aforementioned first groove section 531, that is, the aforementioned knob 6211 can enter or exit the screw-on groove 53 from one end of the first groove section 531. Accordingly, when the knob 6211 moves in the aforementioned first groove section 531, the cleaning component and the connecting member 62 can be moved closer to or farther away from each other in the extension direction of the first groove section 531, thereby realizing the relative position adjustment of the cleaning component and the connecting member 62 in the aforementioned screw-on axial direction; the extension direction of the aforementioned second groove section 532 is different from the extension direction of the first groove section 531, When the knob 6211 moves into the second groove section 532, the side brush assembly 10 and the connecting member 62 can generate relative rotation accordingly. Therefore, based on the movement guiding effect of the second groove section 532 on the knob 6211, relative rotation can be generated between the transmission part 6 and the side brush assembly 10 during the disassembly and assembly process, thereby facilitating the switching between loosening and tightening. The aforementioned third groove section 533 is located on the side of the second groove section 532 close to the aforementioned notch, that is, the extension direction of the aforementioned third groove section 533 is also the same as that of the second groove section 532. The extension direction of the aforementioned second groove section 532 is different, and the first groove section 531 and the third groove section 533 are both located on the same side of the second groove section 532. When the knob 6211 is located in the third groove section 533, the groove wall of the third groove section 533 abuts against the knob 6211 to limit the side brush assembly 10 from moving away from the connecting member 62, that is, to limit the knob 6211 from moving toward the aforementioned groove, thereby achieving the locking of the knob 6211 and ensuring the connection reliability between the side brush assembly 10 and the connecting member 62.

[0181] Furthermore, when the knob 6211 is located in the second groove section 532, a force-applying portion 7 can be provided to apply a force on the transmission portion 6 away from the side brush assembly 10, and to the side brush assembly 10 away from the transmission portion 6, so that based on the force applied by the force-applying portion 7, the transmission portion 6 and the side brush assembly 10 are easily moved away from each other, so that the knob 6211 is correspondingly easy to move from the second groove section 532 to the first groove section 531 and exit the screw-on groove 53, thereby facilitating the disassembly between the side brush assembly 10 and the connecting member 62; or, the knob 6211 is correspondingly easy to move from the second groove section 532 to the third groove section 533, so as to be constrained by the third groove section 533, and hinder the knob 6211 from moving from the third groove section 533 to the second groove section 532, thereby improving the connection reliability between the transmission portion 6 and the side brush assembly 10 when tightening, reducing the risk of the side brush assembly 10 loosening, and facilitating the cleaning assembly to perform the cleaning action smoothly.

[0182] It can be understood that since the first groove section 531 and the third groove section 533 are indirectly connected through the second groove section 532, the spin buckle 6211 cannot move directly between the first groove section 531 and the third groove section 533. Accordingly, the spin buckle 6211 in the third groove section 533 needs to first move in a direction away from the aforementioned slot to enter the second groove section 532, and then move toward the first groove section 531 through the second groove section 532 to disengage from the screw-on groove 53. Based on this, the force applied by the aforementioned force-applying part 7 can hinder the spin buckle 6211 from moving from the third groove section 533 to the second groove section 532, thereby reducing the risk of the spin buckle 6211 falling out of the third groove section 533.

[0183] It can be understood that, based on the above-mentioned arrangement, in actual application, if it is necessary to screw the side brush assembly 10 and the connecting member 62 together, the knob 6211 can be operated to first be inserted into the first slot section 531 and move along the first slot section 531 toward the second slot section 532. After the knob 6211 enters the second slot section 532, the knob 6211 can be further moved from the second slot section 532 toward the third slot section 533 by relatively rotating the side brush assembly 10 and the connecting member 62. When the knob 6211 corresponds to the aforementioned third slot section 533, the user can cancel the operating force applied to the side brush assembly 10 and the connecting member 62, so that the side brush assembly 10 and the connecting member 62 produce a movement away from each other under the action of the force-applying portion 7, so that the knob 6211 enters the third slot section 533 for tightening. In principle, if it is necessary to disassemble the side brush assembly 10 and the connecting member 62, a force can be applied to the side brush assembly 10 and the connecting member 62 to move them closer to each other to overcome the force of the force-applying portion 7, so that the knob 6211 enters the second groove section 532 from the third groove section 533, and then the knob 6211 is further moved from the second groove section 532 to the first groove section 531 by relatively rotating the side brush assembly 10 and the connecting member 62. When the knob 6211 corresponds to the aforementioned first groove section 531, the user can cancel the operating force applied to the side brush assembly 10 and the connecting member 62, so that the side brush assembly 10 and the connecting member 62 move away from each other under the action of the force-applying portion 7, so that the knob 6211 enters the first groove section 531 to be loosened, which is beneficial to improving the disassembly efficiency of the side brush assembly 10.

[0184] As shown in Figures 13 to 15, in some examples, the transmission member 61 includes a transmission gear 611, the connecting member 62 includes a connecting rod 621, the transmission gear 611 is connected to one end of the connecting rod 621, and the connecting rod 621 is coaxially arranged with the transmission gear 611; wherein, a screw-on groove 53 is formed at one end of the connecting rod 621 away from the transmission gear 611; or, a screw buckle 6211 is formed on the circumferential side of the connecting rod 621 and is arranged away from the transmission gear 611.

[0185] In this technical solution, the aforementioned transmission member 61 may include a transmission gear 611, that is, the transmission member 61 can be connected to the driving part through gear transmission, which is beneficial to improving the transmission efficiency; the aforementioned connecting member 62 may include a connecting member 62, the aforementioned transmission gear 611 and the aforementioned connecting rod 621 are connected and coaxially arranged, which is beneficial to improving the rotation stability of the transmission part 6 and providing a guarantee for the side brush assembly 10 to smoothly perform the cleaning action.

[0186] When the screw-on groove 53 is formed in the connecting member 62, the screw-on groove 53 can be opened at the end of the connecting rod 621 away from the transmission gear 611, so as to facilitate the connecting rod 621 to dock with the buckle 6211 on the cleaning component. It can be understood that the screw-on groove 53 can also be coaxial with the connecting rod 621, so as to ensure the rotational stability of the connecting rod 621.

[0187] Alternatively, when the knob 6211 is formed on the connector 62, the knob 6211 may be formed on the peripheral side of the connecting rod 621 and arranged away from the transmission gear 611 so that the connecting rod 621 can dock with the screw-on groove 53 on the cleaning assembly.

[0188] It can be understood that the number of turn buckles 6211 can be more than or equal to one. When the number of turn buckles 6211 is more than one, multiple turn buckles 6211 can be arranged at equal intervals along the circumference of the connecting rod 621 or the side brush assembly 10 to ensure the rotational stability of the connecting rod 621 or the side brush assembly 10, and the number of screw-on grooves 53 can match the number of the aforementioned turn buckles 6211.

[0189] As shown in FIG. 14 and FIG. 15 , in some examples, the transmission gear 611 and the connecting rod 621 are an integrated structure.

[0190] In this technical solution, the transmission gear 611 and the connecting rod 621 can be set as an integrated structure, thereby improving the connection reliability between the transmission gear 611 and the connecting rod 621, providing a more reliable guarantee for the smooth transmission of power, and helping to improve the connection reliability between the transmission part 6 and the side brush assembly 10 when they are in a tightened state.

[0191] As shown in Figures 14 and 15, in some feasible examples, the connecting rod 621 can be a stepped shaft, so that the connecting rod 621 can be easily matched or positioned with other components using a shoulder structure. It is understood that the connecting rod 621 can have multiple shoulder structures, which can be set according to actual needs and are not limited here.

[0192] As shown in FIG. 15 , in some examples, at least a portion of the force applying portion 7 is disposed on the connecting rod 621 and is coaxially arranged with the connecting rod 621 .

[0193] In this technical solution, at least part of the aforementioned force-applying portion 7 can be set on the connecting rod 621. Based on the aforementioned setting, when the side brush assembly 10 is separated from the connecting member 62, at least part of the force-applying portion 7 can be retained on the connecting rod 621, thereby facilitating the cleaning of the side brush assembly 10; and, the force-applying portion 7 can be coaxially arranged with the connecting rod 621, and accordingly, the force-applying portion 7 can also be coaxial with the transmission gear 611, which is beneficial to ensuring the rotational stability of the connecting member 62 and the transmission portion 6.

[0194] As shown in Figures 14 and 15, in some examples, the transmission member 61 is provided with a mounting groove 612 for installing the force-applying part 7, and the mounting groove 612 is provided on the transmission gear 611 and / or the connecting rod 621, and the mounting groove 612 is located in the axial area of ​​the transmission gear 611 and / or the connecting rod 621.

[0195] In this technical solution, the aforementioned mounting groove 612 can be provided in the transmission gear 611 and / or the connecting rod 621, and arranged in the axial region of the transmission gear 611 and / or the connecting rod 621. Based on the above arrangement, the transmission part 6 can use the mounting groove 612 to provide a mounting location and structural protection for the force-applying part 7, thereby reducing the exposure of the force-applying part 7, improving the reliability and stability of the force-applying part 7, and reducing the probability of damage to the force-applying part 7.

[0196] It is understandable that, considering the convenience of connecting the connecting rod 621 and the force-applying portion 7 when docking the side brush assembly 10, the notch end of the mounting groove 612 can be located at the end of the connecting rod 621 away from the transmission gear 611, and the opening length of the mounting groove 612 along the axial direction of the connecting rod 621 can be set in combination with actual needs, and no excessive restrictions are made here. For example, the mounting groove 612 can have a groove section located on the portion of the connecting rod 621 protruding from the transmission gear 611, and a groove section located on the portion of the connecting rod 621 corresponding to the transmission gear 611, and the aforementioned two groove sections are connected to each other; or, it can only have a groove section located on the portion of the connecting rod 621 protruding from the transmission gear 611 to shorten the opening length of the mounting groove 612.

[0197] As shown in Figures 13 to 19, as a specific example of the cleaning component provided by the present disclosure, the force-applying part 7 may include the aforementioned mounting seat 711, the aforementioned support member 712 and the aforementioned spring 713. The aforementioned transmission gear 611 and the aforementioned connecting rod 621 may be an integrated structure. Accordingly, the aforementioned transmission gear 611 and the aforementioned connecting rod 621 are hollow inside to form the aforementioned mounting groove 612. The connecting rod 621 is provided with a through hole at one end away from the transmission gear 611. The mounting seat 711 can be set in the transmission gear 611 and arranged coaxially with the transmission gear 611. The mounting seat 711 and the transmission gear 611 are interference fit so as to rotate synchronously with the transmission gear 611; the aforementioned support member 712 is movably passed through the connecting rod 621 through the aforementioned through hole, and the first support end 7121 is located in the mounting groove 612. The spring 713 is set between the first support end 7121 and the mounting seat 711. Accordingly, the spring 713 is arranged coaxially with the connecting rod 621. Based on this, the axial direction of the connecting rod 621 is also the aforementioned screw-on axial direction. Considering the convenience of cooperation between the side brush assembly 10 and the force-applying part 7 and the transmission part 6, the aforementioned screw-on groove 53 can be opened on the side brush assembly 10, and the aforementioned knob 6211 can be formed on the circumferential side of the aforementioned connecting rod 621 and arranged away from the transmission gear 611. The side brush assembly 10 can also be formed with a passing space for inserting the connecting rod 621, and the passing space is connected with the aforementioned screw-on groove 53, so as to facilitate the synchronous insertion or exit of the side brush assembly 10 by the knob 6211 and the connecting rod 621. The aforementioned limiting groove 52 can be opened on one side of the passing space and connected to the passing space to facilitate docking with the second support end 7122. At the same time, considering the rotation stability of the transmission gear 611, the transmission part 6 can also have a shell 63 and a positioning shaft 64. The aforementioned transmission gear 611 and the aforementioned positioning shaft 64 are both arranged in the aforementioned shell 63, and the aforementioned mounting seat 711 can be provided with a connecting hole, and the connecting hole and the positioning shaft 64 are clearance-matched, so as to constrain the position of the transmission gear 611 and ensure that the transmission gear 611 rotates smoothly.

[0198] In some examples, one of the side brush assembly 10 and the transmission portion 6 is formed with an internal thread, and the other is formed with an external thread.

[0199] In this technical solution, one of the side brush assembly 10 and the transmission part 6 can be formed with an internal thread, and the other can be formed with an external thread, that is, the side brush assembly 10 can be formed with an internal thread and the transmission part 6 can be formed with an external thread, or the side brush assembly 10 can be formed with an external thread and the transmission part 6 can be formed with an internal thread, so that the transmission part 6 and the side brush assembly 10 can be screwed together by threaded screwing, which is beneficial to ensure the convenience of disassembly and assembly between the transmission part 6 and the side brush assembly 10 while improving the connection reliability of the transmission part 6 and the side brush assembly 10 in the assembled state, providing a guarantee for the side brush assembly 10 to perform the cleaning action smoothly.

[0200] The cleaning device provided by the present disclosure includes: a mobile main body 9 and the above-mentioned side brush assembly 10, which is assembled on the mobile main body 9, and the side brush assembly 10 is located at the bottom of the mobile main body 9.

[0201] The cleaning device provided by the present disclosure can prevent the technical problem that the transmission shaft on the cleaning device connected to the base 1 is entangled by hair and stops rotating, so as to avoid affecting the cleaning effect and enable the cleaning device to be used normally; in addition, during the rotation of the side brush assembly 10, the hair accumulated on the blocking part 3 may be thrown out from the side brush part 2 due to the action of centrifugal force, so as to achieve the technical effect of self-cleaning; and when cleaning hair, the user can quickly clean the hair accumulated on the blocking part 3 at one time, so as to improve the user experience.

[0202] In some embodiments, the cleaning device may be a sweeping robot or a mopping robot, or may be other cleaning devices having a side brush assembly 10 , which is not limited here.

[0203] Optionally, the cleaning device provided by the present disclosure further includes a driving assembly and the cleaning assembly proposed in the above embodiment, and the transmission part 6 is transmission-connected to the driving assembly.

[0204] In one example, the drive assembly is configured to drive the base 1 to switch between an installed position and an operating position, thereby enabling the side brush assembly 10 to assist in cleaning. In other words, the drive assembly drives the base 1 to rotate, thereby switching between the installed and operating positions of the base 1. Specifically, when the base 1 is in the operating position, some of the bristles 22 extend beyond the edge projection area of ​​the mobile body 9.

[0205] In another example, the cleaning device further includes a telescopic assembly connected to the base 1 to drive the base 1 to switch between an installation position and a working position. In the installation position, the bristles 22 are located within the projected edge area of ​​the mobile host 9, and in the working position, some of the bristles 22 are located outside the projected edge area of ​​the mobile host 9. In other words, the telescopic assembly drives the base 1 to extend and retract relative to the mobile host 9 to achieve switching between the installation position and the working position of the base 1. It is understood that in this case, the drive assembly is used to drive the base 1 to rotate, such as the drive assembly can drive the base 1 to rotate when the base 1 is in the working position, or the drive assembly can also drive the base 1 to rotate when the base 1 is in the installation position.

[0206] As shown in Figures 20-24, an embodiment of the present disclosure provides a cleaning device, including: a mobile host 9, a side brush assembly 10 of the above embodiment, a main cleaning member 951, a baffle 8 and an active moving member 961, wherein the active moving member 961 is used to move the cleaning body; the baffle 8 and the side brush assembly 10 are both located in front of the main cleaning member 951, and the baffle 8 is located between the two active moving members 961.

[0207] The cleaning equipment can also be called self-cleaning equipment, sweeping machine, cleaning robot or sweeping and mopping machine, etc., which can automatically clean and collect debris without user operation. The mobile host 9 is the main structure of the cleaning equipment. In order to enable the cleaning equipment to adapt to more cleaning space and make the body more stable and balanced, the mobile host 9 is usually flat and round, or it can also have other shapes, such as flat semicircular, square, etc. The mobile host 9 can further include a chassis 91 and a shell 92. The shell 92 includes a storage space that can be used to connect and accommodate various components for the operation of the cleaning equipment, such as a controller for controlling the cleaning components and the walking mechanism, a power supply device, position sensing components such as a camera, a scanner, a gyroscope, a cleaning mechanism, and a walking mechanism. Since the shell 92 is connected to components such as the walking mechanism and the mopping mechanism, the structure and function of the shell 92 are more complicated, including various hollow structures, mounting grooves 612, buckles, and other structures. The chassis 91 is used to connect to the bottom surface of the housing 92. The chassis 91 is usually approximately circular, or as shown in Figures 22-24, approximately semicircular, and can be used to cover some hollowing out of the housing 92, the mounting slots 612, etc., to protect the components in the housing 92 and ensure the simple appearance of the mobile host 9. The chassis 91 and the housing 92 can be connected by bolts, or by snap-on or screw-on methods. The sensing system is provided on the mobile host 9 and is used to sense walls and obstacles, draw maps, and determine the position when the mobile host 9 moves to clean. The sensing system includes sensing devices such as cameras, distance sensors, collision sensors, distance sensors, magnetometers, accelerometers, gyroscopes, and odometers. The cleaning mechanism and the walking mechanism will be described in detail later. It can be understood that the cleaning equipment can also include other necessary components, which will not be listed one by one in this embodiment.

[0208] The cleaning mechanism may include only dry cleaning, or may include both dry cleaning and a mopping system. The mopping system may include a support plate 98, a water tank, etc., which can be used for wet mopping and dry mopping of the ground, which will not be described in detail. Dry cleaning includes a side brush assembly 10 and a main cleaning member 951, as well as a dust box and an exhaust fan, etc. The main cleaning member 951 may be a single roller brush, or two roller brushes arranged axially in parallel, or a retractable roller brush, an anti-entanglement roller brush, etc., which is not limited in this disclosure. Taking the main cleaning member 951 as a single roller brush as an example, the main cleaning member 951 is an approximately cylindrical structure, which is connected to the mobile host 9 through a main drive member. The mobile host 9 has a dust suction port located behind the main cleaning member 951, and the dust box is located in the air path between the exhaust fan and the dust suction port. The main cleaning member 951 has a certain interference with the ground. The main cleaning member 951 is used to rotate around its axis. During the rotation process, the garbage on the ground can be swept up and rolled up to the bottom of the dust suction port, and then sucked into the dust box by the gas generated by the exhaust fan that is drawn back to the dust box. The main cleaning member 951 is usually set in the middle position of the bottom of the mobile host 9. When the mobile host 9 moves, the main cleaning member 951 will follow the moving path of the mobile host 9 to achieve cleaning from line to surface. In this embodiment, the front of the main cleaning member 951 refers to the area corresponding to the direction of the main cleaning member 951 in the moving cleaning, or in other words, it is the area defined by the extension lines of the two axial ends of the main cleaning member 951 perpendicular to the axis, which is the area that the main cleaning member 951 will pass over or pass through when the main cleaning member 951 is moving and cleaning.

[0209] The side brush assembly 10 is approximately propeller-shaped and includes a main shaft, at least one support member 712 circumferentially arranged around the main shaft, and at least one brush head. The main shaft is connected to the mobile main unit 9 via the side brush assembly 10 drive mechanism. The support member 712 is connected to the main shaft and can be straight or curved. The brush head is connected to the support member 712 and can be a bristle brush or a soft rubber brush. As shown in Figures 20-21, the support member 712 is curved in the opposite direction of the side brush assembly 10's rotation, and the brush head extends in the opposite direction of the side brush assembly 10's rotation. This allows for more efficient removal of trash as the side brush assembly 10 rotates. It is understood that the side brush assembly 10 should be located on the side of the main cleaning unit 951 that is moving and cleaning. The side brush assembly 10 should rotate in a direction that causes trash to enter in front of the main cleaning unit 951. As shown in Figure 20, the side brush assembly 10 is located in front of the left side of the main cleaning unit 951 and rotates clockwise. The side brush assembly 10 is mounted near an edge or corner of the mobile unit 9, allowing the brush head to partially extend outside the mobile unit 9. When cleaning corners and the interface between cabinets and floors, the side brush assembly 10 is used to supplement the cleaning missed by the main cleaning unit 951. There can be one or two side brush assemblies 10. If there are two side brush assemblies 10, they can be positioned near opposite ends of the main cleaning unit 951 in the axial direction, providing complementary cleaning on both sides.

[0210] Both the baffle 8 and the side brush assembly 10 are located in front of the main cleaning member 951, that is, in front of the main cleaning member 951 in the direction of movement when the main cleaning member 951 moves forward for cleaning. The specific position of the baffle 8 can be arranged according to the number of side brush assemblies 10 and the actual positions of the mobile unit 9, the main cleaning member 951, etc. Some of the garbage pushed by the side brush assembly 10 will directly enter the front of the main cleaning member 951, while the remaining portion will move in a direction close to the axis of the main cleaning member 951 due to the initial speed of the side brush assembly 10 being too fast or the initial angle being too small with the axis of the main cleaning member 951, and will then be blocked by the baffle 8. Because the baffle 8 is located in front of the main cleaning member 951, the blocked garbage will remain in front of the main cleaning member 951, and then be rolled up by the main cleaning member 951 as it moves for cleaning.

[0211] The running mechanism of cleaning equipment is the main functional equipment of cleaning equipment, and running mechanism mainly comprises active moving member 961 and follower moving member 962.Active moving member 961 protrudes in chassis 91 belows in whole or in part, contacts with the ground, drives by driving motor, and makes active moving member 961 rotate and drive mobile host 9 to walk.Follower moving member 962 can be for being fixed on shell 92 belows, and passes the universal wheel of chassis 91, can realize the turning to of mobile host 9 by cooperating active moving member 961.Follower moving member 962 is usually arranged at mobile host 9 near the front side, and active moving member 961 is respectively set one near the left and right sides at mobile host 9.As active moving member 961, be respectively arranged at the two ends outside opposite to each other of main cleaning part 951 axially.Baffle plate 8 is between two active moving members 961, and promptly baffle plate 8 all zones are all not positioned at the front of active moving member 961, avoids baffle plate 8 to influence cleaning equipment to walk over obstacle. If the active moving member 961 is an obstacle-crossing wheel, when encountering obstacles such as carpets, books, etc., the obstacle can be overcome by the rotation of the obstacle-crossing wheel. If the baffle 8 is located in front of the active moving member 961, it will interfere with the obstacle and cause the cleaning device to jam. The active moving member 961 behind the baffle 8 cannot achieve the obstacle-crossing function. In this embodiment, the baffle 8 is entirely located on the side of the active moving member 961 opposite the main cleaning member 951, so as to prevent the baffle 8 from affecting the movement and obstacle-crossing of the active moving member 961 and ensure the smooth progress of the cleaning device.

[0212] In this embodiment, the baffle 8 can be mounted on the chassis 91, such as being integrally formed with the chassis 91 or detachably connected. Alternatively, the baffle 8 can be connected to the housing 92, with the chassis 91 having a hollow portion, through which the baffle 8 passes, at least partially protruding from the chassis 91. The securing method for the baffle 8 will be further described below with examples. Furthermore, the chassis 91 also includes a clearance opening to allow for the side brush assembly 10, the support plate 98, the main cleaning unit 951, the travel mechanism, and the like.

[0213] The cleaning equipment and cleaning system proposed in the embodiments of the present disclosure are provided with a baffle 8 on the cleaning body. Part of the garbage pushed by the rotation of the side brush assembly 10 will be directly driven to the front of the main cleaning part 951, and the other part of the garbage passing in front of the main cleaning part 951 will be blocked by the baffle 8 and will not continue to move and overflow outside the cleaning body. The garbage blocked by the baffle 8 will move to the front of the main cleaning part 951 and will then be rolled up by the main cleaning part 951, thereby avoiding the overflow of garbage caused by the rotation of the side brush assembly 10 and effectively improving the omissions in cleaning.

[0214] In one embodiment, the baffle 8 is disposed on a side of the mobile host 9 opposite to the side brush assembly 10 .

[0215] As shown in FIG. 20 , the side brush assembly 10 is disposed adjacent to the left side of the mobile main unit 9 , while the baffle 8 is disposed adjacent to the right side of the mobile main unit 9 , so that the main cleaning member 951 can be fully utilized.

[0216] In one embodiment, the cleaning member outer frame 952 and the main cleaning member 951 are located in the cleaning member outer frame 952. Part of the baffle 8 is located in front of the area of ​​the cleaning member outer frame 952 corresponding to one axial end of the main cleaning member 951.

[0217] The cleaning member outer frame 952 is connected to the mobile host 9, and may be a detachable connection to facilitate the disassembly and assembly of the main cleaning member 951. The area of ​​the cleaning member outer frame 952 corresponding to one axial end of the main cleaning member 951 is often lower than the bottom surface of the mobile host 9, or lower than the chassis 91, which makes it easy for garbage to get stuck between the cleaning member outer frame 952 and the surface to be cleaned, scratching the cleaning surface. In this embodiment, a portion of the baffle 8 is located in front of the area of ​​the cleaning member outer frame 952 corresponding to one axial end of the main cleaning member 951, thereby shielding the lower area of ​​the cleaning member outer frame 952 corresponding to the end of the main cleaning member 951, thereby preventing garbage from getting stuck under the cleaning member outer frame 952.

[0218] In one embodiment, the distance between one end of the baffle 8 adjacent to the main cleaning member 951 and the main cleaning member 951 is smaller than a preset distance.

[0219] The preset spacing may be 1 cm to prevent garbage from overflowing from between the baffle 8 and the main cleaning member 951. For example, the spacing may be 0.5 cm, 0.8 cm, etc. In an embodiment including a cleaning member outer frame 952, the spacing between the end of the baffle 8 adjacent to the main cleaning member 951 and the cleaning member outer frame 952 is less than the preset spacing, and may be arranged in close proximity, or be 0.5 cm, 0.8 cm, etc.

[0220] In one embodiment, in the embodiment where the cleaning device further comprises a follower moving member 962, the follower moving member 962 is connected to the mobile host 9 and is configured to roll following the movement of the mobile host 9. The baffle 8 corresponds to between the follower moving member 962 and the main cleaning member 951.

[0221] On the one hand, the distance between the baffle 8 and the main cleaning part 951 is ensured to be less than the preset distance to prevent garbage from overflowing from between the baffle 8 and the main cleaning part 951. On the other hand, the garbage blocked on the baffle 8 is prevented from entering the vicinity of the follow-up moving part 962 to prevent the garbage from affecting the movement of the follow-up moving part 962.

[0222] The baffle 8 can be in various shapes, as long as it can guide the garbage. Four implementation methods are given below as examples. It can be understood that the shape of the baffle 8 is not limited to the following implementation methods.

[0223] First, as shown in Figure 22, the side surface of the baffle 8 relative to the side brush assembly 10 is flat. That is, the baffle 8 is a straight strip structure, which can be a straight strip plate structure or a sheet structure.

[0224] Secondly, as shown in FIG. 23 , a surface of the baffle 8 on one side facing the side brush assembly 10 is an arc-shaped surface that is recessed away from the side brush assembly 10 .

[0225] The baffle 8 is an arc-shaped plate or sheet structure. The arc-shaped setting makes it difficult for garbage to overflow from the end of the baffle 8 away from the main cleaning part 951, and can make the horizontal component of the movement speed of the garbage at the end of the baffle 8 close to the main cleaning part 951 larger, so that the garbage can move more to the middle position of the main cleaning part 951, making full use of the cleaning space.

[0226] Thirdly, a surface of the baffle 8 on one side opposite to the side brush assembly 10 includes a first area 81 and a second area 82 , and the first area 81 and the second area 82 are arranged at an angle.

[0227] For example, the first area 81 and the second area 82 may both be straight strips, and the angle between the first area 81 and the second area 82 may be greater than 90 degrees and less than 180 degrees, so that garbage is not easily overflowed from the end of the baffle 8 away from the main cleaning member 951. Furthermore, the extension direction of the second area 82 may be perpendicular to the axial direction of the main cleaning member 951, so that the second area 82 can extend longer, thereby blocking garbage over a larger area while not occupying the axial cleaning range of the main cleaning member 951.

[0228] Fourthly, as shown in FIG24 , a side surface of the baffle 8 relative to the side brush assembly 10 includes a first area 81 and a second area 82 . The first area 81 is closer to the main cleaning part 951 than the second area 82 . The first area 81 is an arc-shaped surface, and the second area 82 is a plane.

[0229] The second area 82 can extend perpendicularly to the axial direction of the main cleaning member 951. The second area 82 can extend longer, blocking garbage over a wider range while not occupying the axial cleaning range of the main cleaning member 951. The first area 81 is an arcuate surface, which can achieve a greater horizontal component of the movement speed of garbage at the end of the baffle 8 adjacent to the main cleaning member 951, allowing more garbage to move toward the center of the main cleaning member 951, fully utilizing the cleaning space.

[0230] In one embodiment, as shown in FIG. 20 , the baffle 8 includes a first end and a second end, and a direction from the first end of the baffle 8 to the second end of the baffle 8 forms a preset angle γ with the axial direction of the main cleaning member 951 .

[0231] The baffle 8 is tilted relative to the axial direction of the main cleaning member 951, thereby guiding the garbage so that the garbage can slide along the baffle 8 to the front of the main cleaning member 951. The preset angle γ is greater than or equal to 20 degrees and less than or equal to 90 degrees to ensure that the baffle 8 achieves a good guiding effect.

[0232] The first end of the baffle 8 is closer to the main cleaning member 951 than the second end of the baffle 8. The second end of the baffle 8 may be closer to the outside of one end of the main cleaning member 951 than the first end of the baffle 8, or the second end of the baffle 8 may be closer to the inside of the main cleaning member 951 than the first end of the baffle 8, that is, the direction of the baffle 8 close to the second end may be inclined outward or inward.

[0233] In one embodiment, a connecting member 62 is provided on the mobile host 9, and the baffle 8 is detachably connected to the mobile host 9 via the connecting member 62. When the baffle 8 is connected to different connecting members 62, the axial angle between the baffle 8 and the main cleaning member 951 is different.

[0234] Multiple connectors 62 are provided to adjust the angle of the baffle 8. This adjustment can be tailored to the cleaning environment or the speed of the side brush assembly 10, resulting in a better cleaning effect. The connectors 62 can be of various types, such as snaps, bolts, magnetic elements, and adsorption elements. The following describes adjusting the angle of the baffle 8 in conjunction with a more specific embodiment.

[0235] In one embodiment, the baffle 8 is detachably connected to the mobile host 9, and the detachable connection method includes, but is not limited to, at least one of snap connection, screw connection, plug connection, clamp connection, magnetic connection, hanging connection, and bonding.

[0236] For example, both ends of the baffle 8 may be snap-fitted to the chassis 91 of the mobile host 9, or both may be connected by bolts, or a magnetic element may be provided at the bottom of the baffle 8 to be magnetically adsorbed on the chassis 91.

[0237] The baffle 8 can also be connected to the mobile host 9 through an external fixing part. The following example shows an implementation method in which the baffle 8 is fixed to the mobile host 9 by screws to achieve a detachable connection. As shown in Figures 25-26, the cleaning equipment also includes: a connecting bolt 97, a first clamping portion 93 and at least one screw hole are provided on the mobile host 9, and a second clamping portion 85 and a through hole are provided on the baffle 8. The through hole and the second clamping portion 85 are arranged at intervals, such as being arranged at both ends in the length direction of the baffle 8. The second clamping portion 85 and the first clamping portion 93 are clamped to each other, and the connecting bolt 97 passes through the through hole and is screwed to the connecting member 62.

[0238] The first engaging portion 93 can be a slot or a hollow portion as shown in Figure 26 . The second engaging portion 85 can be a protrusion extending outward from the end of the baffle 8 as shown in Figure 26 . The protrusion fits into the slot or hollow portion to retain one end of the baffle 8. The other end of the baffle 8 is retained by a connecting bolt 97 , preventing a single connecting bolt 97 from loosening and causing the baffle 8 to become unstable.

[0239] In the aforementioned embodiment including the connecting member 62, as shown in Figure 22, the connecting member 62 can be the above-mentioned screw hole, and the number of screw holes is at least two, and the different screw holes are arranged circumferentially around the first clamping portion 93, so that when the connecting bolt 97 is connected to different screw holes, the axial angle between the baffle 8 and the main cleaning member 951 is different.

[0240] Figure 22 shows the same baffle 8 at different angles. Baffle a (first baffle 86) has its bolt 97 connected to a screw hole closer to the side brush assembly 10, while baffle b (second baffle 87) has its bolt 97 connected to a screw hole farther from the side brush assembly 10. The provision of multiple screw holes allows for adjustment of the angle of baffle 8, which can be adjusted based on the cleaning environment or the speed of the side brush assembly 10. If the side brush assembly 10 is moving quickly, baffle 8 can be adjusted to a larger angle, such as to baffle a (first baffle 86), to prevent debris from falling onto baffle 8 and overflowing from the second end of baffle 8 due to its high velocity. If the side brush assembly 10 is moving slowly, baffle 8 can be adjusted to a smaller angle, such as to baffle b (second baffle 87), to block debris over a wider axial range of the main cleaning element 951.

[0241] In another embodiment, the baffle 8 is slidably connected to the mobile main unit 9 to change the angle formed by the baffle 8 and the main cleaning member 951 in the axial direction.

[0242] For example, a slide groove may be provided on the mobile host 9, and the baffle 8 is partially embedded in the slide groove, and the baffle 8 moves along the slide groove to achieve the change of angle. Alternatively, a socket may be provided on the mobile host 9, and the baffle 8 is plugged into the socket, and the baffle 8 moves along the socket to achieve the change of angle.

[0243] In one embodiment, as shown in Figures 25-26, the baffle 8 includes a baffle body 83 and a baffle seat 84, and a limiting recess 94 is also provided on the mobile host 9. The baffle body 83 is provided on the chassis 91 of the baffle 8, and the baffle seat 84 is embedded in the limiting recess 94, and the baffle seat 84 is connected to the mobile host 9.

[0244] The baffle body 83 is used to guide the garbage pushed by the side brush assembly 10 to the front, and the baffle seat 84 is used to facilitate the connection between the baffle 8 and the mobile host 9. The aforementioned second clamping portion 85 and the perforation are both provided on the baffle seat 84. The baffle body 83 and the baffle seat 84 can be integrally formed by injection molding, or can be bonded, plugged, hot-melt fixed, ultrasonically welded, etc. The baffle seat 84 can be an approximately rectangular plate-shaped structure, and the limiting recess 94 is adapted to the shape of the baffle seat 84. The aforementioned first clamping portion 93 and at least one connecting member 62 can be provided on the inner wall of the limiting recess 94. The limiting recess 94 is used to limit the position of the baffle 8 chassis 91, making the position of the baffle 8 more stable and the installation more convenient. In some embodiments, the limiting recess 94 is larger than the range of the baffle seat 84, and the baffle seat 84 can slide within the limiting recess 94 to change the angle formed axially by the baffle body 83 and the main cleaning member 951. For example, the baffle seat 84 may abut against the inner wall of the limiting recess 94 on different sides, corresponding to different angles of the baffle body 83 .

[0245] In one embodiment, baffle 8 is fixedly connected to mobile main unit 9. This fixed connection makes baffle 8 more secure and less susceptible to displacement under the impact of garbage. Methods of fixed connection include, but are not limited to, at least one of in-mold injection molding, hot melt fixing, ultrasonic welding, and integrated molding. In a more specific embodiment, baffle 8 can be formed by double-molding a soft rubber strip with a single mold release. Baffle 8 is then fixed to chassis 91 by hot melt welding, ultrasonic welding, or the like, to achieve a fixed connection.

[0246] In one embodiment, baffle 8 is flexible. Specifically, at least a portion of the end of baffle 8 that contacts the surface to be cleaned is flexible, thereby preventing debris from getting stuck between baffle 8 and the surface to be cleaned and potentially scratching it. Baffle 8 can be made of at least one of rubber, silicone, fluororubber, thermoplastic elastomer (TPE), and thermoplastic polyurethane (TPU).

[0247] In one embodiment, the baffle 8 is positioned away from the lowest point of the mobile main unit 9 and closer to the mobile main unit 9 than the main cleaning member 951 is positioned away from the lowest point of the mobile main unit 9, thereby maintaining a gap between the baffle 8 and the surface to be cleaned. This means that during the cleaning process, the main cleaning member 951 interferes with the surface to be cleaned, thereby rolling up debris, while the baffle 8 does not contact the surface to be cleaned. This prevents friction between the baffle 8 and the surface to be cleaned, which could increase the resistance to movement of the mobile main unit 9, and also prevents debris from becoming stuck between the baffle 8 and the surface to be cleaned, potentially scratching the surface.

[0248] Alternatively, in another embodiment, the distance between the lowest point of baffle 8 and the mobile main unit 9 is no less than the distance between the lowest point of the main cleaning member 951 and the mobile main unit 9, so that baffle 8 interferes with the surface to be cleaned. That is, during the cleaning process, both the main cleaning member 951 and baffle 8 interfere with the surface to be cleaned, enabling baffle 8 to more comprehensively block waste and prevent it from overflowing between baffle 8 and the surface to be cleaned. Whether baffle 8 interferes with the surface to be cleaned can be determined based on the material of baffle 8 and the cleaning environment.
