Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a side brush assembly, a cleaning device and a cleaning system. BACKGROUND

[0002] The cleaning device is a common intelligent cleaning appliance, such as a robot vacuum cleaner, an automatic sweeper, etc. The side brush is a key cleaning component of the cleaning device, which is mainly used for cleaning the areas that are difficult to reach, such as the wall edge and the corner.

[0003] During the cleaning process, the side brush rotates and contacts the ground to gather dust, hair, debris and other garbage near the dust suction port of the cleaning device, so as to suck them into the dust box. Hair is easy to entangle on the side brush and accumulate on the rotating shaft of the side brush, thereby affecting the normal operation of the side brush and causing the cleaning effect to be affected.

[0004] In the related art, a complex structure is provided on the side brush to prevent the hair from reaching the rotating shaft area, thereby avoiding the phenomenon that the hair affects the operation of the rotating shaft. However, the hair is easy to be stuck in the complex structure, which increases the difficulty of cleaning the side brush for the user and affects the user experience. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a side brush assembly, a chassis structure, a cleaning device and a cleaning system, which can solve the problem that the hair is easy to entangle on the side brush, thereby affecting the operation of the side brush and affecting the cleaning effect.

[0006] In a first aspect, the present application provides a side brush assembly, comprising:

[0007] a mounting seat for rotating connection to a chassis main body;

[0008] a side brush main body connected with the mounting seat, a free end of the side brush main body away from the mounting seat being used for cleaning a to-be-cleaned surface, the side brush main body comprising a connecting portion;

[0009] a blocking structure protruding from one side of the connecting portion towards the mounting seat, the blocking structure being used for blocking the movement of the hair towards the mounting seat, and the blocking structure and the side brush main body forming an accommodation space for accommodating the hair;

[0010] wherein in a cleaning mode, the side brush main body rotates relative to the chassis main body, part of the chassis main body corresponding to the accommodation space, and part of the chassis main body being used for cleaning the hair in the accommodation space, so that the hair is sucked into the dust suction port on the chassis main body.

[0011] The edge brush assembly provided by the application can prevent the hair from gathering in the direction of the mounting base due to the hair being entangled on the edge brush body and moving along the edge brush body in the direction of the mounting base when the edge brush body rotates to contact the surface to be cleaned. Therefore, the blocking structure protruding from the side of the edge brush body in the direction of the mounting base can prevent the hair entangled on the edge brush body from gathering in the direction of the mounting base. The hair is kept in the accommodation space under the blocking of the blocking structure, so that the possibility of the hair winding into the mounting base and affecting the rotational connection between the mounting base and the main body of the chassis can be reduced.

[0012] The blocking structure and the edge brush body form an accommodation space. It should be noted that the accommodation space is an open space. The hair can be entangled on the blocking structure or the connecting part, so that at least part of the hair is located in the accommodation space. Therefore, the hair can be gathered in the accommodation space, so that the user can regularly clean the hair in the accommodation space, and the cleaning process is relatively simple.

[0013] Alternatively, the edge brush assembly of the embodiment of the application can cooperate with part of the main body of the chassis during rotation to clean the hair in the accommodation space, so that the hair in the accommodation space is automatically cleaned, the user does not need to manually clean the hair accumulated at the blocking structure, time and labor can be saved, and the user experience can be improved.

[0014] Specifically, the hair on the edge brush body can be gathered in the accommodation space by the blocking structure. Part of the main body of the chassis corresponding to the accommodation space can mean that part of the main body of the chassis can extend into at least part of the accommodation space during the rotation of the edge brush body. Part of the main body of the chassis can contact the hair accumulated in the accommodation space, and the rotation of the edge brush body can make the main body of the chassis carry the hair in the accommodation space out of the accommodation space. The hair can be separated from the accommodation space, so that the possibility of the hair entering the mounting base and affecting the rotation of the mounting base relative to the main body of the chassis can be reduced, and the hair on the edge brush body can also be self-cleaned.

[0015] After the hair is separated from the accommodation space, the hair can fall onto the surface to be cleaned under the action of its own gravity, so that the hair is sucked into the dust box of the main body of the chassis through the suction port under the action of the suction force of the suction port. In addition, due to the light weight of the hair, the hair can also be directly sucked into the suction port under the action of the suction force during the falling process.

[0016] According to one embodiment of the application, the connecting part and the surface of part of the main body of the chassis opposite to each other are in interference contact in the direction in which the blocking structure protrudes from the connecting part.

[0017] In the embodiments of the present application, the sufficient contact of the connecting portion with the partial base body can improve the cleaning effect and cleaning efficiency of the hair in the containing space.

[0018] Specifically, during the cleaning process, the bristle body has a certain pressure on the surface to be cleaned to ensure the cleaning effect on the surface to be cleaned. In other words, the bristle body and the surface to be cleaned have a relative force. The bristle body is flexible and can deform in the direction of the base body under the action of the surface to be cleaned, so that the bristle body moves in the direction of the base body, and the connecting portion and the blocking structure also move in the direction of the base body at the same time. At this time, the connecting portion and the surface opposite to the base body can also have an interference contact, therefore, the surface to be cleaned and the bristle body, and the bristle body and the partial base body are not easy to have a longitudinal gap therebetween, so as to avoid the hair moving in the direction of the mounting seat through the longitudinal gap. The longitudinal gap can refer to the gap in the height direction of the bristle body.

[0019] According to an embodiment of the present application, the blocking structure includes a hanging portion and an extension portion, the hanging portion is fixed to the connecting portion through the extension portion, the hanging portion, the extension portion and the connecting portion form the containing space, and the opening of the containing space is towards the free end.

[0020] In the embodiments of the present application, the free end of the bristle body is in contact with the surface to be cleaned to clean the surface to be cleaned, therefore, the hair on the surface to be cleaned can move in the direction of the mounting seat from the direction of the free end. By setting the opening of the containing space formed by the hanging portion, the extension portion and the connecting portion towards the free end, the hair rolled in by the free end can directly enter the containing space through the opening.

[0021] According to an embodiment of the present application, along the radial direction of the mounting seat, the hanging portion is located on the side of the bristle body towards the mounting seat, and the hanging portion and the bristle body have a first gap therebetween.

[0022] In the embodiments of the present application, by setting the hanging portion on the side of the bristle body towards the mounting seat, the hanging portion is closer to the mounting seat, therefore, the hair can be blocked from moving in the direction of the mounting seat along the radial direction of the mounting seat.

[0023] Specifically, when the hair moves in the direction of the mounting seat, the hanging portion can block the hair at the first gap. Along the radial direction of the mounting seat, the surfaces opposite to each other of the hanging portion and the bristle body can have the effect of clamping and accommodating the hair at the first gap, so as to relatively fix the hair at the first gap. The hair at the first gap is not easy to move in the direction of the mounting seat.

[0024] According to one embodiment of the present application, the connecting portion has a fixed surface facing the mounting base, and the hanging portion is projected from the connecting portion along the direction of the blocking structure, and the projection of the hanging portion is located outside the fixed surface.

[0025] In the embodiments of the present application, the projection of the hanging portion and the fixed surface do not have an overlapping area and have a spacing along the direction of the blocking structure. Therefore, the hair accumulated in the blocking structure can fall down to the surface to be cleaned through the first gap under the action of suction force and be sucked into the suction port, so that the accumulation amount of hair in the accommodation space can be reduced, and the difficulty of cleaning the hair accumulated in the accommodation space by the partial base body can be reduced.

[0026] In other words, along the radial direction of the mounting base, the hanging portion and the connecting portion are arranged staggered, so that the hair is blocked, and the clamping effect of the hanging portion and the connecting portion on the hair in the first gap is not too large, and the hair is not easy to be stuck in the first gap, so that when the brush assembly moves, the hair is more easily taken away from the first gap by the partial base body contacting the connecting portion, and is sucked into the suction port by the suction force.

[0027] Therefore, the hanging portion can block the movement of the hair along the radial direction of the mounting base to the direction of the mounting base, so that the possibility of the hair entering the mounting base and affecting the rotation of the mounting base is reduced.

[0028] According to one embodiment of the present application, the first gap is at least 0.8 mm.

[0029] In the embodiments of the present application, when the first gap is less than 0.8 mm, the particulate matter on the surface to be cleaned is easy to be stuck in the first gap, which is not conducive to the storage of hair, and is easy to cause the first gap to be blocked, so that the hair is blocked from the first gap. And when the first gap is too small, the hair is also easy to be clamped in the first gap. When the brush assembly rotates, the partial base body is not easy to take the hair out of the accommodation space. By setting the first gap to be greater than or equal to 0.8 mm, the above technical problems can be effectively solved.

[0030] According to one embodiment of the present application, along the direction of the blocking structure projecting from the connecting portion, the hanging portion and the fixed surface have a second gap.

[0031] In the embodiments of the present application, when the hair moves along the extension direction of the brush body to the direction of the mounting base, the extension portion can have a blocking effect on the hair. The extension portion can block the hair in the second gap between the hanging portion and the fixed surface. The hanging portion and the fixed surface can have a clamping and storing effect on the hair at the second gap, so that the hair at the second gap is not easy to move along the extension direction of the brush body to the direction of the mounting base.

[0032] In a direction in which the blocking structure protrudes from the connecting portion, the hanging portion and the fixing surface can be staggered to make the hanging portion and the fixing surface have a smaller clamping effect on the hair at the second gap, so that the hair is less likely to be stuck at the second gap, and thus the hair can be more easily taken away from the second gap by the partial bottom body when the edge brush assembly moves.

[0033] According to an embodiment of the present application, the second gap is at least 0.8 mm.

[0034] In the embodiment of the present application, when the second gap is less than 0.8 mm, the particulate matter on the surface to be cleaned is easily stuck in the second gap, which is not conducive to the storage of the hair and is also likely to block the second gap, causing the hair to be difficult to escape from the second gap. Moreover, when the second gap is too small, the hair is also likely to be clamped in the second gap. When the edge brush assembly rotates, the partial bottom body is not easy to take the hair out of the accommodation space. By setting the second gap to be greater than or equal to 0.8 mm, the above technical problems can be effectively solved.

[0035] According to an embodiment of the present application, in a direction in which the blocking structure protrudes from the connecting portion, a dimension between an end surface of the blocking structure facing the mounting seat and the fixing surface is at least 3 mm.

[0036] In the embodiment of the present application, the end surface of the blocking structure facing the mounting seat can refer to an end portion of the blocking structure in the direction protruding from the connecting portion and away from the fixing surface. By setting the dimension between the end surface of the blocking structure facing the mounting seat and the fixing surface to be at least 3 mm, the overall strength of the blocking structure can be ensured, and the possibility that the hanging portion is damaged due to the pulling between the hair and the hanging portion when the hair is entangled in the hanging portion or in the process of cleaning the hair by the partial bottom body can be reduced.

[0037] Especially, when the dimensions of the first gap and / or the second gap are large, the dimension between the end surface of the blocking structure facing the mounting seat and the fixing surface can be correspondingly increased to improve the strength of the blocking structure.

[0038] According to an embodiment of the present application, the edge brush body includes a connecting arm and a brush body connected in sequence, the connecting arm is connected with the mounting seat, and the brush body is arranged at an end of the connecting arm away from the mounting seat.

[0039] The connecting portion is located on the connecting arm and close to the brush body, and the free end is located on the brush body.

[0040] The blocking structure is arranged on the connecting arm, and in a direction in which the blocking structure protrudes from the connecting portion, a projection of the hanging portion is located outside a projection of the brush body.

[0041] In the embodiments of the present application, in the direction in which the blocking structure protrudes from the connecting portion, when the orthographic projection of the hanging portion and the orthographic projection of the brush body have an overlapping area, the hair can accumulate between the brush body and the hanging portion. The brush body generally includes bristles. Since the bristles are thin, when the hair is entangled on the bristles, the hair is not easy to be separated from the bristles, thereby causing the phenomenon that the bristles are difficult to clean. Moreover, when part of the bottom body carries the hair away from the accommodation space, the hair is easy to be pulled by the bristles and damage the bristles. Therefore, by arranging the orthographic projection of the hanging portion outside the orthographic projection of the brush body, the above technical problems can be effectively solved.

[0042] Moreover, since the flexibility of the brush body is higher than that of the connecting arm, when the brush body is in deep contact with the surface to be cleaned, the deformation amount of the brush body can be greater than that of the connecting arm. By arranging the orthographic projection of the hanging portion and the orthographic projection of the brush body without an overlapping area, when the brush body is deformed in the direction of the bottom body, the contact between the brush body and the hanging portion can be reduced, thereby causing the brush body to block the opening of the accommodation space and reducing the possibility that the hair enters or separates from the accommodation space.

[0043] According to an embodiment of the present application, the brush body includes a plurality of the connecting arms, and the connecting arms are arranged one by one corresponding to the brush body. At least one blocking structure is arranged on each connecting arm.

[0044] In the embodiments of the present application, when the number of connecting arms is multiple, the blocking structure can be arranged on each connecting arm, so as to reduce the movement of the hair in the direction of the mounting seat, thereby affecting the rotation of the mounting seat.

[0045] In a second aspect, the present application provides a bottom structure, which includes:

[0046] The brush assembly in any of the above embodiments;

[0047] The bottom body is provided with a cleaning structure, which is used to contact the brush assembly in the cleaning mode, and the cleaning structure is used to clean the hair at the blocking structure.

[0048] In the embodiments of the present application, during the rotation of the brush assembly relative to the bottom body, the brush assembly can be deformed in the direction of the bottom body under the action of the surface to be cleaned, so that the accommodation space for accumulating the hair on the bottom body can correspond to the cleaning structure, thereby the cleaning structure can separate the hair from the accommodation space. The hair can be sucked into the suction port and enter the dust box under the action of the suction force.

[0049] According to an embodiment of the present application, the cleaning structure includes a cleaning rib protruding from the bottom body, and the cleaning rib is in interference contact with the connecting portion of the brush body.

[0050] The cleaning rib has simple structure, is convenient to produce, and has low cost.

[0051] According to an embodiment of the present application, the interference amount between the connecting part and the cleaning rib is between 0.5mm and 1mm in the direction in which the connecting part protrudes from the blocking structure.

[0052] In the embodiment of the present application, the contact depth between the brush body and the surface to be cleaned is different when the bottom disc structure cleans different surfaces to be cleaned. In addition, the contact depth between the brush body and the surface to be cleaned is also different when the brush assembly rotates at different speeds. Therefore, the deformation amount of the brush body in the direction of the bottom disc body is different. By setting the interference amount between the connecting part and the cleaning rib to be greater than or equal to 0.5mm, the cooperation stability of the connecting part and the cleaning rib can be ensured, thereby ensuring the cleaning effect of the cleaning rib on the hair at the accommodation space.

[0053] When the interference amount between the connecting part and the cleaning rib is greater than 1mm, the friction between the cleaning rib and the connecting part is large, which on the one hand easily increases the rotation resistance of the brush assembly and affects the cleaning effect, and also increases the energy consumption and reduces the endurance. On the other hand, the cleaning rib and the connecting part are prone to produce abnormal sound, affecting the user experience.

[0054] According to an embodiment of the present application, the cleaning structure includes a plurality of cleaning ribs arranged at intervals, a guide channel is formed between two adjacent cleaning ribs, one end of the guide channel corresponds to the movement track of the blocking structure, the other end of the guide channel corresponds to the dust suction port on the bottom disc body, so as to guide the hair from the blocking structure to the dust suction port.

[0055] In the embodiment of the present application, by arranging a plurality of cleaning ribs, a guide channel for guiding the hair at the accommodation space to the dust suction port can be formed between two adjacent cleaning ribs. The hair can enter the dust suction port along the guide channel, so as to reduce the possibility of the hair floating to the outside of the cleaning device and causing secondary pollution. In addition, the guide channel can converge the suction force, so as to improve the suction force on the hair at the accommodation space and improve the cleaning effect on the hair at the accommodation space.

[0056] The hair can be wound on the blocking structure under the action of the blocking structure. With the rotation of the brush assembly, the movement track of the blocking structure can form an arc-shaped (for example, circular, elliptical, etc.) track. Taking the circular track of the movement track of the blocking structure as an example (shown by the dashed line in the figure), when the brush assembly rotates, the hair moves synchronously with the blocking structure, and the movement track of the hair is also circular. Therefore, one end of the guide channel can correspond to any position of the circular track, which can make the hair smoothly enter the guide channel. The hair can enter the dust suction port along the inner wall of the guide channel from the blocking structure.

[0057] According to an embodiment of the present application, the guiding passage corresponds to one end of the movement track of the blocking structure in the advancing direction of the chassis body.

[0058] In the embodiment of the present application, one end of the guiding passage can be directed towards the advancing direction of the chassis body. Therefore, during the advancing of the chassis body, the hair accumulated on the blocking structure can enter the suction port through the guiding passage, and the hair on the surface to be cleaned can also enter the suction port along the guiding passage.

[0059] According to an embodiment of the present application, the width of the guiding passage gradually increases in the direction of the suction of the hair in the guiding passage.

[0060] In the embodiment of the present application, the hair at the blocking structure moves in the direction of the guiding passage towards the suction port. Therefore, the entrance end of the guiding passage is the end corresponding to the movement track of the blocking structure. The exit end of the guiding passage is the end corresponding to the suction port. The width of the guiding passage gradually increases in the direction from the entrance end to the exit end of the guiding passage.

[0061] Since the entrance end of the guiding passage is farther away from the suction port than the exit end, the suction force at the entrance end of the guiding passage is smaller than that at the exit end. By setting the width of the entrance end to be relatively small, the suction force at the entrance end can be increased, so that when the cleaning rib contacts the connecting part and sweeps the hair at the accommodation space, there is enough suction force to suck all the hair separated from the accommodation space into the guiding passage as much as possible.

[0062] Furthermore, by setting the width of the guiding passage to gradually increase from the entrance end to the exit end, the movement of the hair in the guiding passage can be smoother, which is conducive to improving the cleaning effect of the hair on the blocking structure.

[0063] According to an embodiment of the present application, the minimum width in the guiding passage is greater than or equal to 3mm.

[0064] During the rotation of the side brush assembly, small particles on the surface to be cleaned are easily rolled into the guiding passage. By setting the minimum width in the guiding passage to be greater than or equal to 3mm, the small particles can smoothly pass through the guiding passage and enter the suction port, so that the small particles are not easily stuck in the guiding passage, which is conducive to reducing the possibility of the small particles blocking the guiding passage and affecting the hair being sucked into the suction port along the guiding passage.

[0065] According to an embodiment of the present application, the height of the plurality of cleaning ribs gradually increases in the direction away from the center of the mounting seat in the radial direction of the mounting seat.

[0066] In the embodiments of the present application, the contact depth between the side brush assembly and the surface to be cleaned is different when the rotation speed of the side brush assembly is different, and the deformation amount of the side brush body in the direction of the chassis body is also different. By setting different heights of the plurality of cleaning ribs, at least one cleaning rib can be in contact with the connecting portion of the side brush body when the deformation amount of the side brush body in the direction of the chassis body is different, so that the cleaning rib can sweep the hair at the accommodation space.

[0067] It is easy to understand that the distance between the side brush body and the chassis body gradually increases in the direction away from the center of the mounting seat along the radial direction of the mounting seat, and therefore, the heights of the plurality of cleaning ribs also gradually increase in this direction correspondingly, so as to avoid the possibility that the cleaning rib collides with the side brush body or the contact depth is too large, which affects the movement resistance of the side brush assembly or even affects the operation of the side brush assembly.

[0068] According to an embodiment of the present application, the cleaning structure is detachably connected to the chassis body.

[0069] In the embodiments of the present application, since the connecting portion of the cleaning structure can be in contact with the side brush body for sweeping the hair at the accommodation space, dirt is easy to be generated on the cleaning structure. Therefore, by detachably connecting the cleaning structure to the chassis body, the user can conveniently clean the cleaning structure.

[0070] In addition, since the cleaning rib of the cleaning structure is made of flexible material, when the cleaning rib is worn, the cleaning structure can be conveniently maintained and replaced without replacing the entire chassis body.

[0071] In a third aspect, the present application provides a cleaning device, which comprises the chassis structure of any of the above embodiments.

[0072] In a fourth aspect, the present application provides a cleaning system, which comprises a base station and a cleaning device. The cleaning device can be placed on the base station.

[0073] The side brush assembly provided by the present application has the following beneficial effects: the blocking structure can block the movement of the hair in the direction of the mounting seat, so as to reduce the possibility that the hair accumulates in the mounting seat and affects the rotation performance of the mounting seat. In addition, through the cooperative movement of the cleaning structure on the chassis body and the side brush body, the hair accumulated at the blocking structure can be swept away, so that the hair can be separated from the blocking structure and sucked into the suction port under the action of the suction force. The user does not need to manually clean the hair on the side brush assembly, which is conducive to realizing the self-cleaning of the side brush assembly and improving the user experience.

[0074] In addition to the technical problems solved by the embodiments of the utility model described above, the technical features constituting the technical solutions and the beneficial effects brought by these technical features, other technical problems solved by the edge brush assembly, the chassis structure, the cleaning equipment and the cleaning system provided by the embodiments of the utility model, other technical features contained in the technical solutions and the beneficial effects brought by these technical features will be further explained in detail in the specific embodiments.

[0094] The specific embodiments of the present application have been shown by the above drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0095] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims. It is clear that the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the present application.

[0096] The cleaning device provided by the embodiments of the present application can be, but is not limited to, a sweeping machine. Taking the sweeping machine as an example, the sweeping machine is a device for cleaning the ground. The cleaning function of the sweeping machine is mainly realized by high-speed rotation of the motor. The high-speed rotation of the motor can form a vacuum in the machine body to use high-speed airflow to suck dust, hair and other dirt on the ground into the machine body from the suction port. The dirt can be accumulated in the cloth bag machine or dust box for the convenience of the user to clean regularly.

[0097] The side brush is a key cleaning component of the sweeping machine, and is mainly used for cleaning areas such as the edge of the wall and the corner of the wall that are difficult to reach. During the cleaning process, the side brush rotates and contacts the ground to gather dust, hair, debris and other garbage near the dust suction port of the cleaning device, so as to suck them into the dust box. Hair (for example, human hair, pet hair, lint on clothes, etc.) is easy to entangle on the side brush and accumulate on the rotating shaft of the side brush, thereby affecting the normal operation of the side brush and causing the cleaning effect to be affected.

[0098] In the related art, a complex structure is arranged on the side brush to prevent hair from reaching the rotating shaft area, thereby avoiding the phenomenon that hair affects the rotation of the rotating shaft. However, the hair is easy to be stuck in the complex structure, and the user has difficulty in cleaning the side brush, which affects the user experience.

[0099] Based on the above technical problems, the applicant improves the structure of the existing side brush assembly. In the embodiment of the present application, the accommodation space for accommodating hair is formed between the blocking structure and the side brush body, which can block the hair in the accommodation space, so that the hair is not easy to move towards the mounting seat, thereby avoiding the hair entering the mounting seat to affect the rotation performance of the mounting seat relative to the chassis body.

[0100] In addition, the side brush body rotates relative to the chassis body. During the rotation of the side brush body, part of the structure on the chassis body can correspond to the accommodation space for cleaning the hair in the accommodation space. The part of the structure on the chassis body can take the hair away from the accommodation space, and then the hair can be sucked into the dust box under the suction force of the dust suction port of the chassis body. Therefore, the automatic cleaning of the hair accumulated in the accommodation space can be realized, so that the user does not need to manually clean the hair on the side brush, which is helpful to improve the user experience.

[0101] The side brush assembly 100, the chassis structure 10, the cleaning device and the cleaning system provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0102] Referring to Figures 1 to 4 The side brush assembly 100 of the embodiment of the present application includes a mounting seat 110, a side brush body 120 and a blocking structure 130.

[0103] The mounting seat 110 is used for rotating connection to the chassis body 200. The side brush body 120 is connected with the mounting seat 110. The free end 122a of the side brush body 120 away from the mounting seat 110 is used for sweeping the surface to be cleaned. The side brush body 120 includes a connecting part 1211.

[0104] The blocking structure 130 is protrudingly arranged on the side of the connecting part 1211 towards the mounting seat 110. The blocking structure 130 is used for blocking the movement of the hair towards the mounting seat 110. The blocking structure 130 and the side brush body 120 form an accommodation space 100a for accommodating the hair.

[0105] In the cleaning mode, the side brush body 120 rotates relative to the chassis body 200. Part of the chassis body 200 can correspond to the accommodation space 100a. Part of the chassis body 200 can be used for cleaning the hair in the accommodation space 100a, so that the hair is sucked into the dust suction port 200a on the chassis body 200. It should be noted that the position of the dust suction port 200a is schematically represented in the figure.

[0106] The side brush assembly 100 can be rotatably connected to the bottom disc main body 200 through the mounting seat 110. During rotation of the side brush assembly 100, the free end 122a of the side brush main body 120 is in contact with the surface to be cleaned, so as to roll the dirt on the surface to be cleaned into the direction of the dust suction port 200a. Since the surface to be cleaned has hair, and the hair is soft in texture, when the side brush main body 120 rotates to contact the surface to be cleaned, the hair is easily entangled on the side brush main body 120 and moves along the side brush main body 120 to the direction of the mounting seat 110.

[0107] In the embodiment of the present application, the blocking structure 130 is protrudingly arranged on the side of the side brush main body 120 facing the mounting seat 110, so that the blocking structure 130 can block the hair entangled on the side brush main body 120 from accumulating in the direction of the mounting seat 110. The hair is kept in the accommodation space 100a under the blocking action of the blocking structure 130, so that the possibility of the hair rolling into the mounting seat 110 and affecting the rotatable connection between the mounting seat 110 and the bottom disc main body 200 can be reduced.

[0108] The blocking structure 130 and the side brush main body 120 form an accommodation space 100a therebetween. It should be noted that the accommodation space 100a is an open space. The hair can be entangled on the blocking structure 130 or the connecting portion 1211, so that at least part of the hair is located in the accommodation space 100a. Therefore, the hair can be accumulated in the accommodation space 100a, so that the user can periodically clean the hair in the accommodation space 100a, and the cleaning process is relatively simple.

[0109] Alternatively, during rotation of the side brush assembly 100 of the embodiment of the present application, the hair in the accommodation space 100a can be cleaned by cooperating with part of the bottom disc main body 200, so that the hair in the accommodation space 100a is automatically cleaned, and the user does not need to manually clean the hair accumulated at the blocking structure 130, which can save time and effort and improve user experience.

[0110] Specifically, the hair on the side brush main body 120 can be accumulated in the accommodation space 100a by the blocking structure 130. Part of the bottom disc main body 200 corresponding to the accommodation space 100a can mean that part of the bottom disc main body 200 can extend into at least part of the accommodation space 100a during rotation of the side brush main body 120. Part of the bottom disc main body 200 can be in contact with the hair accumulated in the accommodation space 100a, and through rotation of the side brush main body 120, the bottom disc main body 200 can carry the hair in the accommodation space 100a out of the accommodation space 100a. The hair can be separated from the accommodation space 100a, so that the possibility of the hair entering the mounting seat 110 and affecting the rotation of the mounting seat 110 relative to the bottom disc main body 200 can be more effectively reduced, and the hair on the side brush main body 120 can also be self-cleaned.

[0111] After the hair is separated from the accommodation space 100a, the hair can fall onto the surface to be cleaned under the action of its own gravity, so that the hair is sucked into the dust box of the main body 200 through the suction port 200a under the action of the suction force of the suction port 200a. In addition, due to the light weight of the hair, the hair can also be directly sucked into the suction port 200a under the action of the suction force in the process of falling downward.

[0112] In some examples, the blocking structure 130 and the edge brush body 120 can be an integral structure. Alternatively, the blocking structure 130 can also be fixed to the connecting portion 1211 of the edge brush body 120 by clamping, bonding, screwing or the like, which is not limited in the embodiment.

[0113] It should be noted that during the cleaning process, the edge brush body 120 can be in deep contact with the surface to be cleaned, wherein the deep contact between the edge brush body 120 and the surface to be cleaned can mean that the edge brush body 120 has a certain interference with the surface to be cleaned in the height direction of the main body 200, so as to ensure the cleaning effect of the surface to be cleaned. The edge brush body 120 can be deformed in the direction of the main body 200 under the action of the surface to be cleaned, so that the edge brush body 120 approaches the main body 200, so that part of the main body 200 can correspondingly enter the accommodation space 100a formed by the edge brush body 120 and the blocking structure 130. Part of the main body 200 can be in contact with the hair at the accommodation space 100a, so that part of the main body 200 can carry the hair away from the accommodation space 100a by rotating the edge brush body 120.

[0114] In some examples, referring to Figure 2 As shown, the edge brush body 120 and the surface to be cleaned have an inclination angle, so that the free end 122a can be in full contact with the surface to be cleaned. The side of the blocking structure 130 protruding from the connecting portion 1211 towards the mounting seat 110 can mean that the blocking structure 130 protrudes from the surface of the edge brush body 120 away from the surface to be cleaned in the height direction of the edge brush body 120. When the edge brush body 120 is in deep contact with the surface to be cleaned, at least part of the edge brush body 120 can be parallel to the surface to be cleaned.

[0115] It should be noted that the hair has flexibility and is easy to wind on the edge brush body 120, therefore, the accumulation of the hair in the accommodation space 100a can mean that at least part of the hair is wound on the blocking structure 130 or the connecting portion 1211, so that at least part of the hair is relatively fixed at the accommodation space 100a and is not easy to move towards the mounting seat 110.

[0116] In some examples, the extension shape of the edge brush body 120 can be but not limited to an Archimedes spiral line type.

[0117] In some implementable manners, referring to Figure 2 As shown, along the direction in which the connecting portion 1211 protrudes from the blocking structure 130, the connecting portion 1211 is in interference contact with the surface of the partial chassis body 200 opposite to the connecting portion 1211.

[0118] It should be noted that the interference contact between the connecting portion 1211 and the surface of the partial chassis body 200 opposite to the connecting portion 1211 can mean that, when the bristle body 120 is in deep contact with the surface to be cleaned, the bristle body 120 deforms in the direction of the chassis body 200, so that the partial chassis body 200 and the connecting portion 1211 can have a contact depth. Therefore, the partial chassis body 200 and the connecting portion 1211 can be in sufficient contact for cleaning the hair at the accommodation space 100a.

[0119] In the embodiments of the present application, through the sufficient contact between the connecting portion 1211 and the partial chassis body 200, the cleaning effect and the cleaning efficiency of the hair at the accommodation space 100a can be improved.

[0120] Specifically, during the cleaning process, the bristle body 120 has a certain pressure on the surface to be cleaned to ensure the cleaning effect on the surface to be cleaned. In other words, the bristle body 120 and the surface to be cleaned have a relative force. The bristle body 120 is flexible, and the bristle body 120 can deform in the direction of the chassis body 200 under the action of the surface to be cleaned, so that the bristle body 120 moves in the direction of the chassis body 200, and thus the connecting portion 1211 and the blocking structure 130 also move in the direction of the chassis body 200. At this time, the connecting portion 1211 and the surface of the chassis body 200 opposite to the connecting portion 1211 can also be in interference contact, and thus the surface to be cleaned and the bristle body 120 and the bristle body 120 and the partial chassis body 200 are not easy to have a longitudinal gap, so as to avoid the hair moving in the direction of the mounting seat 110 through the longitudinal gap. The longitudinal gap can mean the gap in the height direction of the bristle body 120.

[0121] In some examples, during the rotation of the bristle assembly 100, the partial chassis body 200 can be in sufficient contact with at least part of the surface of the connecting portion 1211 facing the chassis body 200.

[0122] In some implementable manners, referring to Figure 2 and Figure 4 As shown, the blocking structure 130 of the embodiments of the present application includes a hanging portion 131 and an extension portion 132. The hanging portion 131 can be fixed to the connecting portion 1211 through the extension portion 132. The hanging portion 131, the extension portion 132 and the connecting portion 1211 form the accommodation space 100a. The opening of the accommodation space 100a faces the free end 122a.

[0123] In this embodiment, the free end 122a of the side brush body 120 contacts the surface to be cleaned to clean it. Therefore, hair on the surface to be cleaned can move from the direction of the free end 122a toward the mounting base 110. By setting the opening of the receiving space 100a formed by the suspension part 131, the extension part 132, and the connecting part 1211 to face the free end 122a, hair rolled up by the free end 122a can directly enter the receiving space 100a through the opening.

[0124] See also some of the possible implementation methods. Figure 5 As shown, along the radial direction of the mounting base 110, the suspension portion 131 is located on the side of the side brush body 120 facing the mounting base 110. A first gap m exists between the suspension portion 131 and the side brush body 120.

[0125] It should be noted that, since the side brush body 120 can extend in an Archimedean spiral shape, the radial direction of the mounting base 110 in this embodiment is not strictly radial. For example, see the first gap m. Figure 5 As shown.

[0126] In this embodiment, by setting the suspension part 131 on the side of the side brush body 120 facing the mounting base 110, the suspension part 131 is closer to the mounting base 110, thus preventing hair from moving radially toward the mounting base 110.

[0127] Specifically, when the hair moves toward the mounting base 110, the suspension part 131 can block the hair at the first gap m. Along the radial direction of the mounting base 110, the surfaces of the suspension part 131 and the side brush body 120 facing each other can clamp and collect the hair at the first gap m, so that the hair is relatively fixed at the first gap m. The hair at the first gap m is not easy to move toward the mounting base 110.

[0128] See also some of the possible implementation methods. Figure 5 As shown, the connecting portion 1211 of this embodiment has a fixing surface 1211a facing the mounting base 110. Along the direction in which the blocking structure 130 protrudes from the connecting portion 1211, the orthogonal projection of the suspension portion 131 is located outside the fixing surface 1211a.

[0129] In this embodiment, along the protruding direction of the blocking structure 130, the orthographic projection of the suspension portion 131 and the fixing surface 1211a do not overlap and are spaced apart. Therefore, hair fragments accumulated in the blocking structure 130 can fall downwards through the first gap m onto the surface to be cleaned, and be sucked into the suction port 200a under the action of suction force, thereby reducing the amount of hair accumulated in the receiving space 100a and reducing the difficulty for part of the chassis body 200 to clean the hair accumulated in the receiving space 100a.

[0130] In other words, the suspension part 131 and the connecting part 1211 are staggered along the radial direction of the mounting base 110. This ensures that the clamping effect of the suspension part 131 and the connecting part 1211 on the hair in the first gap is not too great when blocking the hair. The hair is not easy to get stuck in the first gap m. So when the side brush assembly 100 moves, the hair is more easily removed from the first gap m by contacting the connecting part 1211 through part of the chassis body 200, and is sucked into the suction port 200a by the suction force.

[0131] Therefore, the suspension part 131 can prevent hair from moving radially toward the mounting base 110, thereby reducing the possibility of hair entering the mounting base 110 and affecting the rotation of the mounting base 110.

[0132] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, in this embodiment of the application, the first gap m is at least 0.8 mm.

[0133] In this embodiment, when the first gap m is less than 0.8 mm, particles on the surface to be cleaned are easily trapped in the first gap m, which is not conducive to the collection of hair and can easily cause blockage of the first gap m, preventing hair from detaching from the first gap m. Furthermore, when the first gap m is too small, hair is also easily clamped into the first gap m. When the side brush assembly 100 rotates, part of the base body 200 is not able to easily carry hair out of the receiving space 100a. Setting the first gap m to be greater than or equal to 0.8 mm can effectively solve the above-mentioned technical problems.

[0134] See also some of the possible implementation methods. Figure 6 As shown, along the direction in which the blocking structure 130 protrudes from the connecting portion 1211, there is a second gap n between the suspension portion 131 and the fixing surface 1211a.

[0135] In this embodiment, when hair moves along the extension direction of the side brush body 120 toward the mounting base 110, the extension portion 132 can block the hair. The extension portion 132 can block the hair within the second gap n between the suspension portion 131 and the fixing surface 1211a. The suspension portion 131 and the fixing surface 1211a can clamp and store the hair at the second gap n, so that the hair at the second gap n is less likely to move along the extension direction of the side brush body 120 toward the mounting base 110.

[0136] In other words, along the direction in which the blocking structure 130 protrudes from the connecting part 1211, the suspension part 131 and the fixing surface 1211a can be staggered so that the clamping effect of the suspension part 131 and the fixing surface 1211a on the hair at the second gap n is smaller, and the hair is less likely to get stuck at the second gap n. Thus, when the side brush assembly 100 moves, the hair can be more easily removed from the second gap n by part of the chassis body 200.

[0137] See also some of the possible implementation methods. Figure 4 and Figure 6 As shown, the second gap n in this embodiment of the application is at least 0.8 mm.

[0138] In this embodiment, when the second gap n is less than 0.8 mm, particles on the surface to be cleaned are easily trapped in the second gap n, which is not conducive to the collection of hair and can easily clog the second gap n, making it difficult for hair to detach from the second gap n. Furthermore, when the second gap n is too small, hair is also easily clamped into the second gap n. When the side brush assembly 100 rotates, part of the base body 200 is not able to easily carry hair out of the receiving space 100a. Setting the second gap n to be greater than or equal to 0.8 mm can effectively solve the above-mentioned technical problems.

[0139] See also some of the possible implementation methods. Figure 5 As shown, along the direction in which the blocking structure 130 protrudes from the connecting portion 1211, the dimension t between the end face of the blocking structure 130 facing the mounting base 110 and the fixing surface 1211a is at least 3 mm.

[0140] In this embodiment, the end face of the blocking structure 130 facing the mounting base 110 can refer to the end of the blocking structure 130 protruding from the connecting portion 1211 and away from the fixing surface 1211a. By setting the dimension t between the end face of the blocking structure 130 facing the mounting base 110 and the fixing surface 1211a to be at least 3mm, the overall strength of the blocking structure 130 can be guaranteed, reducing the possibility of damage to the hanging portion 131 caused by hair pulling between the hair and the hanging portion 131 when hair is wrapped around it, or during the process of cleaning hair from part of the chassis body 200.

[0141] In particular, when the dimensions of the first gap m and / or the second gap n are large, the dimension t between the end face of the blocking structure 130 facing the mounting base 110 and the fixing surface 1211a can be increased accordingly to improve the strength of the blocking structure 130.

[0142] See also some of the possible implementation methods. Figure 5As shown, the side brush body 120 includes a connecting arm 121 and a brush body 122 connected together. The connecting arm 121 is connected with the mounting base 110. The brush body 122 is arranged at an end of the connecting arm 121 away from the mounting base 110. The connecting part 1211 is located on the connecting arm 121 and close to the brush body 122. The free end 122a is located on the brush body 122. The blocking structure 130 is arranged on the connecting arm 121, and the normal projection of the hanging part 131 is located outside the normal projection of the brush body 122 in the direction in which the blocking structure 130 protrudes from the connecting part 1211.

[0143] At least part of the brush body 122 is in contact with the surface to be cleaned for cleaning the surface to be cleaned. The connecting arm 121 can be used to connect the brush body 122 and the mounting base 110. The connecting arm 121 can have good wear resistance and elasticity, so that when the brush body 122 is in deep contact with the surface to be cleaned, the connecting arm 121 can be deformed under the action of the surface to be cleaned. The deformation of the connecting arm 121 can relieve the force acting on the brush body 122 from the surface to be cleaned, thereby prolonging the service life of the brush body 122.

[0144] In the embodiment of the present application, in the direction in which the blocking structure 130 protrudes from the connecting part 1211, when the normal projection of the hanging part 131 has an overlapping area with the normal projection of the brush body 122, the hair can accumulate between the brush body 122 and the hanging part 131. The brush body 122 usually includes bristles. Since the bristles are thin, when the hair is entangled with the bristles, the hair is not easy to be separated from the bristles, thereby causing the phenomenon that the bristles are difficult to clean. Moreover, when part of the bottom plate body 200 carries the hair away from the accommodation space 100a, the hair is easy to be pulled and damaged with the bristles. Therefore, by arranging the normal projection of the hanging part 131 outside the normal projection of the brush body 122, the above technical problems can be effectively solved.

[0145] Moreover, since the flexibility of the brush body 122 is higher than that of the connecting arm 121, when the brush body 122 is in deep contact with the surface to be cleaned, the deformation amount of the brush body 122 can be greater than that of the connecting arm 121. By arranging the normal projection of the hanging part 131 without overlapping area with the normal projection of the brush body 122, when the brush body 122 is deformed in the direction of the bottom plate body 200, the contact between the brush body 122 and the hanging part 131 can be reduced, thereby preventing the brush body 122 from blocking the opening of the accommodation space 100a and the possibility that the hair is difficult to enter or separate from the accommodation space 100a.

[0146] In some possible implementation manners, referring to Figure 4 As shown, in the embodiment of the present application, the side brush body 120 can include a plurality of connecting arms 121. The connecting arms 121 are arranged one by one with the brush body 122. At least one blocking structure 130 is arranged on each connecting arm 121.

[0147] In the embodiments of the present application, when the number of the connecting arms 121 is multiple, each of the connecting arms 121 can be provided with the blocking structure 130, so as to reduce the movement of the hair to the direction of the mounting seat 110, thereby affecting the rotation of the mounting seat 110.

[0148] For example, the number of the connecting arms 121 can be but is not limited to three.

[0149] In the embodiments of the present application, the connecting arm 121 can be provided with multiple blocking structures 130. The multiple blocking structures 130 can be distributed at intervals along the extension direction of the connecting arm 121. For example, the number of the blocking structures 130 can be two, three or even more.

[0150] In some examples, the multiple connecting arms 121 can be distributed in a spiral shape along the circumference of the mounting seat 110.

[0151] The embodiments of the present application also provide a chassis structure 10, as shown in Figure 2 The chassis structure 10 can include the edge brush assembly 100 and the chassis body 200 in any of the above-mentioned embodiments.

[0152] The chassis body 200 is provided with a cleaning structure 210. The cleaning structure 210 is used to contact the edge brush assembly 100 in the cleaning mode. The cleaning structure 210 is used to clean the hair at the blocking structure 130.

[0153] In the embodiments of the present application, during the rotation of the edge brush assembly 100 relative to the chassis body 200, the edge brush assembly 100 can be deformed to the direction of the chassis body 200 under the action of the surface to be cleaned, so that the accommodation space 100a for accumulating the hair on the chassis body 200 can correspond to the cleaning structure 210, so that the cleaning structure 210 can separate the hair from the accommodation space 100a. The hair can be sucked into the suction port 200a and enter the dust box under the action of the suction force.

[0154] In some realizable ways, as shown in Figure 4 、 Figure 7 and Figure 8 The cleaning structure 210 includes a cleaning rib 211 protruding from the chassis body 200. The cleaning rib 211 is in interference contact with the connecting part 1211 of the edge brush body 120.

[0155] In the embodiments of the present application, in the cleaning mode, the edge brush body 120 is in deep contact with the surface to be cleaned, so that the cleaning rib 211 is in interference contact with the connecting part 1211 of the edge brush body 120. The structure of the cleaning rib 211 is simple, easy to process and produce, and the cost is low. Moreover, the cleaning rib 211 can also improve the structural strength of the chassis body 200.

[0156] In some examples, the cleaning rib 211 can but not limited to a plate structure. The plate structure can have a large surface area to take the hair in the accommodation space 100a away by the surface of the plate structure.

[0157] In some examples, during the cleaning process, the bristle body 120 can be deformed in the direction of the cleaning rib 211. At this time, the cleaning rib 211 can be in interference contact with the fixed surface 1211a of the connecting part 1211 to improve the cleaning rate of the hair in the accommodation space 100a.

[0158] In some realizable ways, along the direction of the blocking structure 130 protruding from the connecting part 1211, the interference amount of the connecting part 1211 and the cleaning rib 211 is between 0.5mm-1mm.

[0159] In the embodiments of the present application, the contact depth between the bristle body 120 and the surface to be cleaned is different when the chassis structure 10 cleans different surfaces to be cleaned. And the contact depth between the bristle body 120 and the surface to be cleaned is also different when the bristle assembly 100 rotates at different speeds. Therefore, the deformation amount of the bristle body 120 in the direction of the chassis body 200 is different. By setting the interference amount of the connecting part 1211 and the cleaning rib 211 to be greater than or equal to 0.5mm, the cooperation stability of the connecting part 1211 and the cleaning rib 211 can be guaranteed, thereby guaranteeing the cleaning effect of the cleaning rib 211 on the hair at the accommodation space 100a.

[0160] When the interference amount of the connecting part 1211 and the cleaning rib 211 is greater than 1mm, the friction between the cleaning rib 211 and the connecting part 1211 is large, which on the one hand easily increases the rotation resistance of the bristle assembly 100 and affects the cleaning effect, and also causes the energy consumption to increase, reduces the endurance capability. On the other hand, the cleaning rib 211 and the connecting part 1211 are easy to produce abnormal sound, affecting the user experience.

[0161] Wherein, along the direction of the blocking structure 130 protruding from the connecting part 1211, the interference amount of the connecting part 1211 and the fixed surface 1211a is between 0.5mm-1mm.

[0162] In some examples, the bristle assembly 100 can have a lifting function. By lifting the bristle assembly 100, the interference amount of the connecting part 1211 and the cleaning rib 211 can be adjusted, so that the interference amount can be within 0.5mm-1mm, thereby guaranteeing the cleaning rate of the hair at the blocking structure 130 and guaranteeing the operation reliability of the bristle assembly 100.

[0163] In some realizable ways, referring to Figure 4 , Figure 7 and Figure 8As shown, the cleaning structure 210 of the embodiment of the present application includes a plurality of cleaning ribs 211 arranged at intervals. A guide channel 220 is formed between two adjacent cleaning ribs 211. One end of the guide channel 220 corresponds to the movement trajectory of the blocking structure 130. The other end of the guide channel 220 corresponds to the dust suction port 200a on the base body 200, so as to guide the hair from the blocking structure 130 to the dust suction port 200a.

[0164] In the embodiment of the present application, by arranging a plurality of cleaning ribs 211, a guide channel 220 for guiding the hair at the containing space 100a to the dust suction port 200a can be formed between two adjacent cleaning ribs 211. The hair can enter the dust suction port 200a along the guide channel 220, so as to reduce the possibility of the hair floating to the outside of the cleaning device and causing secondary pollution. Moreover, the guide channel 220 can converge the suction force, so as to improve the suction force on the hair at the containing space 100a and improve the cleaning effect on the hair at the containing space 100a.

[0165] The hair can be wound on the blocking structure 130 under the action of the blocking structure 130. With the rotation of the edge brush assembly 100, the movement trajectory of the blocking structure 130 can form an arc-shaped (for example, circular, elliptical, etc.) trajectory. Taking the circular trajectory of the movement trajectory of the blocking structure 130 as an example (as shown by the dashed line), when the edge brush assembly 100 rotates, the hair moves synchronously with the blocking structure 130, and the movement trajectory of the hair is also circular. Therefore, one end of the guide channel 220 can correspond to any position of the circular trajectory, and the hair can smoothly enter the guide channel 220. The hair can enter the dust suction port 200a along the inner wall of the guide channel 220 from the blocking structure 130. Figure 4

[0166] It should be noted that when the number of cleaning ribs 211 is a plurality, at least one cleaning rib 211 is in contact with the connecting portion 1211, that is, the hair at the containing space 100a can be swept. The number of cleaning ribs 211 in contact with the connecting portion 1211 is not limited in the embodiment.

[0167] In some examples, the material of the cleaning rib 211 can be a flexible material to avoid damage to the surface to be cleaned. For example, the material of the cleaning rib 211 can be, but is not limited to, silica gel, TPU (thermoplastic polyurethane elastomer), rubber, etc.

[0168] In some implementable manners, referring to Figure 3 and Figure 4 As shown, along the advancing direction of the base body 200, one end of the guide channel 220 corresponding to the movement trajectory of the blocking structure 130 is arranged forward.

[0169] ​In the embodiments of the present application, one end of the guide channel 220 can be directed towards the forward direction of the chassis body 200. Therefore, during the forward movement of the chassis body 200, the hair accumulated on the blocking structure 130 can enter the dust suction port 200a through the guide channel 220, and the hair on the surface to be cleaned can also enter the dust suction port 200a along the guide channel 220.

[0170] In some possible implementations, referring to Figure 4 As shown, along the direction of the suction of the hair in the guide channel 220, the width of the guide channel 220 gradually increases.

[0171] In the embodiments of the present application, the hair at the blocking structure 130 moves along the guide channel 220 towards the dust suction port 200a. Therefore, the inlet end 220a of the guide channel 220 is the end corresponding to the movement track of the blocking structure 130. The outlet end 220b of the guide channel 220 is the end corresponding to the dust suction port 200a. Along the direction from the inlet end 220a to the outlet end 220b of the guide channel 220, the width of the guide channel 220 gradually increases.

[0172] Since the inlet end 220a of the guide channel 220 is farther away from the suction port than the outlet end 220b, the suction force at the inlet end 220a of the guide channel 220 is smaller than that at the outlet end 220b. By setting the width of the inlet end 220a to be relatively small, the suction force at the inlet end 220a can be increased, so that when the cleaning rib 211 is in contact with the connecting part 1211 and the hair in the containing space 100a is swept, there is enough suction force to suck the hair separated from the containing space 100a into the guide channel 220 as much as possible.

[0173] In addition, by setting the width of the guide channel 220 to gradually increase from the inlet end 220a to the outlet end 220b, the movement of the hair in the guide channel 220 can be smoother, which is beneficial to improve the cleaning effect of the hair on the blocking structure 130.

[0174] In some examples, the cleaning rib 211 can have an arc-shaped plate structure. The arc-shaped plate structure can reduce the resistance of the hair moving in the guide channel 220, which is beneficial to improve the cleaning efficiency of the hair at the blocking structure 130.

[0175] In some possible implementations, the minimum width of the guide channel 220 is greater than or equal to 3 mm.

[0176] During the rotation of the side brush assembly 100, small particles on the surface to be cleaned are easily rolled into the guide channel 220. By setting the minimum width of the guide channel 220 to be greater than or equal to 3 mm, the small particles can smoothly pass through the guide channel 220 and enter the suction port 200a, so that the small particles are not easily stuck in the guide channel 220, which is beneficial to reduce the possibility of blocking the guide channel 220 by the particles and affecting the hair being sucked into the suction port 200a along the guide channel 220.

[0177] It should be noted that the minimum width of the guide channel 220 can be set according to the application environment of the cleaning device. In a general home environment, the minimum width of the guide channel 220 is greater than or equal to 3 mm, which can meet the cleaning requirements.

[0178] In some examples, the width of the inlet end 220a of the guide channel 220 can be the smallest. Therefore, when the small particles can smoothly enter the inlet end 220a of the guide channel 220, they can then move smoothly in the guide channel 220 under the action of the suction force and be sucked into the suction port 200a.

[0179] In some implementable manners, referring to FIG. 6, the heights of the plurality of cleaning ribs 211 gradually increase in a direction away from the center of the mounting seat 110 along the radial direction of the mounting seat 110. Figure 8

[0180] In the embodiments of the present application, the contact depth between the side brush assembly 100 and the surface to be cleaned is different when the rotation speed of the side brush assembly 100 is different, and the deformation amount of the side brush body 120 in the direction of the chassis body 200 is also different. By setting different heights of the plurality of cleaning ribs 211, at least one cleaning rib 211 can be in contact with the connecting part 1211 of the side brush body 120 when the deformation amount of the side brush body 120 in the direction of the chassis body 200 is different, so that the cleaning rib 211 can sweep the hair at the accommodation space 100a.

[0181] It is easy to understand that the distance between the side brush body 120 and the chassis body 200 gradually increases in a direction away from the center of the mounting seat 110 along the radial direction of the mounting seat 110, and therefore, correspondingly, the heights of the plurality of cleaning ribs 211 also gradually increase in this direction, so as to avoid the possibility of collision or excessive contact between the cleaning ribs 211 and the side brush body 120, which affects the movement resistance of the side brush assembly 100 or even affects the operation of the side brush assembly 100.

[0182] In some implementable manners, the cleaning structure 210 is detachably connected to the chassis body 200.

[0183] ​In the embodiments of the present application, the cleaning structure 210 can be in contact with the connecting portion 1211 of the side brush body 120 to clean the hair accumulated at the accommodation space 100a. Therefore, the cleaning structure 210 can be detachably connected to the chassis body 200, so that the user can clean the cleaning structure 210 conveniently.

[0184] In addition, the cleaning rib 211 of the cleaning structure 210 is made of flexible material. When the cleaning rib 211 is worn, the cleaning structure 210 can be maintained and replaced conveniently without replacing the entire chassis body 200.

[0185] In some examples, the cleaning structure 210 can be detachably connected to the chassis body 200 by clamping, screwing or the like.

[0186] The cleaning device provided in the embodiments of the present application can include the above-described chassis structure 10.

[0187] The cleaning device provided in the embodiments of the present application can block the movement of the hair toward the mounting seat 110 through the blocking structure 130, so as to reduce the possibility that the hair is accumulated at the mounting seat 110 and affects the rotation performance of the mounting seat 110. In addition, the hair accumulated at the blocking structure 130 can be cleaned through the cooperation of the cleaning structure 210 on the chassis body 200 and the side brush body 120, so that the hair can be separated from the blocking structure 130 and sucked into the suction port 200a under the action of the suction force. The user does not need to clean the hair on the side brush assembly 100 manually, which is beneficial to realize the self-cleaning of the side brush assembly 100 and improve the user experience.

[0188] The cleaning system provided in the embodiments of the present application can include a base station and a cleaning device. The cleaning device can be placed on the base station.

[0189] The base station can have a charging function. When the cleaning device is placed on the base station, the base station can charge the cleaning device.

[0190] The base station can also have a cleaning function. When the cleaning device is placed on the base station, the cleaning module such as the roller brush, the cleaning cloth, the side brush assembly 100 and the like on the cleaning device can be cleaned.
