Description
Technical Field
[0001] This application relates to the technical field of cleaning products, and particularly to a cleaning device. Background Art
[0002] Cleaning devices such as mite cleaners, vacuum cleaners, and floor sweeping robots are commonly used in households. Vacuum cleaners and floor sweeping robots can clean the floor, and mite cleaners can remove dust and mites on the surfaces of mattresses, leather, etc.
[0003] In related technologies, a cleaning device generally includes a housing and a fan unit disposed inside the housing. The airflow generated by the fan unit creates suction at the air inlet of the housing. A rotating brush may be provided at the position corresponding to the air inlet. The rotating brush rolls on the surface to be cleaned to pick up dust and hair, and the dust and hair are sucked into the device through the suction of the air inlet to achieve the cleaning function.
[0004] However, during the cleaning process of current cleaning devices, hair is easily wound around the rotating brush and cannot be sucked into the device. Summary of the Utility Model
[0005] This application provides a cleaning device to solve the technical problem that during the cleaning process of current cleaning devices, hair is easily wound around the rotating brush and cannot be sucked into the device.
[0006] This application provides a cleaning device, which includes a device main body and a rotating brush assembly. The device main body has a receiving groove, and the rotating brush assembly is rotatably disposed in the receiving groove.
[0007] The device main body is provided with a first air inlet at the front end of the receiving groove along a first direction, and a second air inlet at the rear end of the receiving groove along the first direction; the device main body has an air suction channel, and both the first air inlet and the second air inlet are communicated with the air suction channel. The second air inlet may include a first air suction side and a second air suction side. The first air suction side is communicated with the receiving groove and is opposite to the rotating brush assembly, and the second air suction side faces the bottom side of the device main body.
[0008] The cleaning device provided by the embodiment of this application is provided with multiple air inlets on the device main body, which are respectively arranged at the front end and the rear end of the rotating brush assembly. During the cleaning process, the air inlet at the front end can suck away some hair fibers on the surface to be cleaned first, and the remaining hair brought up by the rotating brush assembly can be sucked away by the air inlet at the rear end. The air inlet at the rear end has multiple air suction sides. In addition to sucking away the fiber hair brought up by the rotating brush assembly, it can also directly suck in the residual fiber hair on the surface to be cleaned, thereby avoiding the entanglement and knotting of a large amount of hair fibers brought up by the rotation of the rotating brush assembly and improving the cleaning efficiency.
[0009] As an optional implementation manner, the first air inlet may extend along a second direction, and the second direction is perpendicular to the first direction.
[0010] With such a setting, the first air suction port can be in a long strip structure along the second direction. During the cleaning process, the first air suction port can more easily suck away the fibers and hairs distributed along the second direction first, shunt the hair fibers to be cleaned on the surface to be cleaned, and improve the cleaning efficiency.
[0011] As an alternative implementation, the roller brush assembly extends along the second direction, and the length of the first air suction port matches the length of the roller brush assembly.
[0012] With such a setting, the coverage range of the first air suction port can be equivalent to the cleaning range of the roller brush assembly, improving the efficiency of shunting and sucking away the lateral hair fibers.
[0013] As an alternative implementation, the widths of the first air suction port at different positions along the second direction are equal.
[0014] With such a setting, the limited space at the front end of the accommodation groove of the device main body can be fully utilized, and the suction balance at different positions in the length direction of the first air suction port can be ensured.
[0015] As an alternative implementation, the orientation of the first air suction side is perpendicular to the orientation of the second air suction side.
[0016] With such a setting, the suction area of the second air suction port can be increased, and the efficiency of the second air suction port sucking in dust, mites, and fiber hairs can be improved.
[0017] As an alternative implementation, there are air guiding walls on both sides of the second air suction port, and the air guiding walls extend to the outside of the second air suction port.
[0018] With such a setting, it can play a guiding role in the suction air flow of the second air suction port, and guide the dust and impurities lifted by the roller brush assembly to flow into the air suction channel along with the air flow, preventing the dust and impurities from falling back onto the surface to be cleaned.
[0019] As an alternative implementation, the first air suction port faces the bottom side of the device main body; the distance between the first air suction port and the plane where the bottom side of the device main body is located is 10 mm - 15 mm.
[0020] With such a setting, on the one hand, it prevents the first air suction port from being too close to the surface to be cleaned and hindering the air flow, and on the other hand, it prevents the first air suction port from being too far from the surface to be cleaned and having insufficient suction for the fiber hairs on the surface to be cleaned.
[0021] As an alternative implementation, the device main body can include a first housing, a second housing, and a third housing. Both the second housing and the third housing are connected to the first housing; the second housing is configured to form the first air suction port; the third housing is configured to form the air suction channel, and the second air suction port is located on the side of the third housing facing the bottom of the device main body.
[0022] With such a setting, the convenience of production and assembly of the device main body can be improved, and the production cost can be reduced.
[0023] As an alternative implementation, the second housing has an air inlet passage, the first air suction port is located at the first end of the air inlet passage, a ventilation port is provided on one side of the third housing facing the first housing, and the second end of the air inlet passage is docked and communicated with the ventilation port.
[0024] With such a setting, it can ensure the smoothness of the fiber hair inhaled by the first air suction port entering the air suction passage along with the air flow.
[0025] As an alternative implementation, a receiving groove is formed by surrounding the outer wall of the second housing.
[0026] With such a setting, the cross-sectional contour of the air inlet passage fits around the circumferential side of the receiving groove, making full use of the structural space on the device main body and improving the compactness of the structure.
[0027] As an alternative implementation, the roller brush assembly may include a roller and a flexible cleaning member, and the flexible cleaning member is connected to the surface of the roller; the diameter of the middle position of the roller along the second direction is smaller than the diameter of the two end positions of the roller along the second direction; the second air suction port is opposite to the middle position of the roller along the second direction.
[0028] With such a setting, the hair rolled up by the roller brush assembly will gather towards the position close to the second air suction port and is more likely to be sucked into the air suction port, rather than becoming more and more entangled on the roller brush assembly, which is more convenient for cleaning the roller brush assembly.
[0029] The present application provides a cleaning device, including a device main body and a roller brush assembly. The device main body has a receiving groove, and the roller brush assembly is rotatably arranged in the receiving groove. The device main body is provided with a first air suction port at the front end of the receiving groove along the first direction, and a second air suction port at the rear end of the receiving groove along the first direction; the device main body has an air suction passage, and both the first air suction port and the second air suction port are communicated with the air suction passage. The second air suction port may include a first air suction side and a second air suction side. The first air suction side is communicated with the receiving groove and is opposite to the roller brush assembly, and the second air suction side faces the bottom side of the device main body. During the cleaning process, the air suction port at the front end can suck away some hair fibers first, and the remaining hair fibers lifted by the roller brush assembly can be sucked away by the air suction port at the rear end, thereby avoiding the entanglement and knotting of a large number of hair fibers lifted by the rolling of the roller brush assembly and improving the cleaning efficiency.

[0044] The terms "first", "second", "third" (if any) in the description, claims, and drawings of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.
[0045] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.
[0047] A cleaning device generally includes a housing and a blower unit disposed within the housing. An air flow generated by the blower unit creates a suction force at the suction opening of the housing. A rolling brush may be provided at a position corresponding to the suction opening. The rolling brush rolls on the surface to be cleaned to pick up dust and hair, and the suction force at the suction opening sucks the dust and hair into the device interior to achieve the cleaning function.
[0048] However, during the cleaning process of current cleaning devices, hair is easily wound around their roller brushes and cannot be sucked into the device interior. Taking a mite remover as an example, a mite remover can remove dust and worms on the surfaces of beddings, leather materials, etc. There is usually a lot of hair adhering to the beddings. When the roller brush of the mite remover rolls on the surface of the bedding, the hair is easily wound around the roller brush, and as the roller brush rolls, the wound hair will become tighter and tighter towards both ends of the roller brush and cannot be sucked away, which also makes the cleaning of the roller brush time-consuming and laborious.
[0049] To solve the above technical problems, the embodiments of the present application provide a cleaning device. Through the structural design of the air suction openings on the cleaning device, air suction openings are respectively arranged on the front and rear sides of the roller brush assembly along the cleaning direction, and multiple air suction openings are used to shunt the fiber hair on the surface to be cleaned, so that the fiber hair is respectively sucked into the device interior under the suction force of the multiple air suction openings, reducing the amount of hair wound around the roller brush, improving the cleaning efficiency, and making it more convenient to clean the roller brush after cleaning.
[0050] First, an example description of the application scenario of the cleaning device provided by the embodiments of the present application will be given below.
[0051] The cleaning device provided by the embodiments of the present application is a cleaning tool with a roller brush structure. Specifically, the product types of the cleaning device in the embodiments of the present application may include but are not limited to mite removers, vacuum cleaners, floor sweepers, floor sweeping robots, etc. According to different product types, the cleaning device provided by the embodiments of the present application can be used to clean floors, clothes, quilts, sofa furniture, etc., and the embodiments of the present application do not make specific limitations thereto.
[0052] Figure 1 is a schematic structural diagram of the cleaning device provided by the embodiments of the present application; Figure 2 is a schematic diagram of the setting of the roller brush assembly in the device main body provided by the embodiments of the present application; Figure 3 is a cross-sectional view of the cleaning device provided by the embodiments of the present application.
[0053] See Figures 1 to 3 As shown, the present application provides a cleaning device 10, which includes a device main body 200 and a roller brush assembly 100. The device main body 200 has a receiving groove 201, and the roller brush assembly 100 is rotatably arranged in the receiving groove 201. When the cleaning device 10 performs a cleaning operation, the side of the device main body 200 connected to the roller brush assembly 100 faces the surface to be cleaned, and the roller brush assembly 100 can contact the surface to be cleaned. As the device main body 200 moves, the roller brush assembly 100 rolls on the surface to be cleaned, and the roller brush assembly 100 can pick up impurities such as dust, fiber hair, etc. on the surface to be cleaned, making it easier for the dust, fiber hair, etc. to be sucked into the device main body 200 interior.
[0054] Among them, the device main body 200 is provided with a first air suction port 202 at the front end of the accommodation groove 201 along the first direction, and the device main body 200 is provided with a second air suction port 203 at the rear end of the accommodation groove 201 along the first direction. The device main body 200 has an air suction channel 204, and both the first air suction port 202 and the second air suction port 203 are communicated with the air suction channel 204. The second air suction port 203 may include a first air suction side 203a and a second air suction side 203b. The first air suction side 203a is communicated with the accommodation groove 201 and is opposite to the roller brush assembly 100, and the second air suction side 203b faces the bottom side of the device main body 200.
[0055] Define the first direction as the X direction, the X direction is the cleaning direction of the cleaning device 10, that is, the rolling direction of the roller brush assembly 100, define the second direction as the Y direction, and the Y direction is the axial direction of the roller brush assembly 100.
[0056] It can be understood that the first air suction port 202 is located at the front end of the device main body 200 along the X direction, and the second air suction port 203 is located at the rear end of the accommodation groove 201 along the X direction. When the cleaning device 10 moves and cleans along the X direction, the first air suction port 202 first passes through the area to be cleaned. Then, the roller brush assembly 100 contacts the area to be cleaned. Then, the second air suction port 203 passes through the area to be cleaned. In this way, during the cleaning process, the first air suction port 202 and the second air suction port 203 can respectively suck in fiber hairs to shunt the fiber hairs in the area to be cleaned.
[0057] It should be noted that in the cleaning device 10 provided in the embodiment of the present application, the first air suction port 202 and the second air suction port 203 are respectively arranged at the front end and the rear end of the roller brush assembly 100. During the cleaning process, the air suction port located at the front end can suck away some hair fibers first, and the remaining hair fibers lifted by the roller brush assembly 100 can be sucked away by the air suction port at the rear end, thereby avoiding a large amount of hair fibers lifted by the rotation of the roller brush assembly 100 from being entangled and knotted.
[0058] In addition, since the second air suction port 203 includes multiple air suction sides, in addition to sucking away the fiber hairs lifted by the roller brush assembly 100, it can also directly suck in the fiber hairs remaining on the surface to be cleaned. Among them, the fiber hairs rolled up by the roller brush assembly 100 can be sucked into the air suction channel 204 from the first air suction side 203a, thereby preventing the hair from being wound around the roller brush assembly 100 as the roller brush assembly 100 rotates. The dust and hair remaining on the surface to be cleaned, as well as the dust and hair that fall back to the surface to be cleaned after being rolled up by the roller brush assembly 100, can be sucked into the air suction channel 204 from the second air suction side 203b, improving the cleaning efficiency.
[0059] Next, the structure of the first air suction port 202 will be described in detail.
[0060] Figure 4 ForFigure 3 Partial view of position A in the middle.
[0061] Please refer to Figures 1 to 4 In a possible implementation, the first air suction port 202 can extend along a second direction, and the second direction is perpendicular to the first direction. The length direction of the first air suction port 202 is parallel to the axial direction of the roller brush assembly 100.
[0062] It can be understood that the first air suction port 202 can be a strip-shaped structure along the second direction, that is, the first air suction port 202 extends along the Y direction. During the cleaning process, the first air suction port 202 can more easily suck away the fibers and hairs distributed along the second direction first, shunt the hair fibers to be cleaned on the surface to be cleaned, and improve the cleaning efficiency.
[0063] Exemplarily, the second direction is defined as the transverse direction and the first direction is defined as the longitudinal direction. The fiber hairs on the surface to be cleaned may be distributed in a disorderly and interlaced manner in the transverse and longitudinal directions. During the cleaning process when the cleaning device 10 moves along the X direction, the posture of the fiber hairs distributed in the transverse direction corresponds to the extension direction of the first air suction port 202, and the first air suction port 202 can suck the fiber hairs distributed in the transverse direction into it, while the remaining longitudinal fibers can be lifted by the roller brush assembly 100 and sucked into the second air suction port 203.
[0064] It should be noted that since the fiber hairs are soft in texture, the transverse fibers can be understood as fiber hairs extending along the Y direction, or fiber hairs with a posture close to the Y direction. Similarly, the longitudinal fibers can be understood as fiber hairs extending along the X direction, or fiber hairs with a posture close to the X direction. The embodiments of the present application do not make specific limitations on this.
[0065] In some embodiments, the roller brush assembly 100 extends along the second direction, and the length of the first air suction port 202 matches the length of the roller brush assembly 100, so that the coverage range of the first air suction port 202 can be equivalent to the cleaning range of the roller brush assembly 100, and the efficiency of shunting and sucking away the transverse hair fibers can be improved.
[0066] It can be understood that the first air suction port 202 can extend from one end of the device body 200 along the Y direction to the other end at the front end of the device body 200. The length of the suction area of the first air suction port 202 matches the length of the cleaning area where the roller brush assembly 100 contacts the surface to be cleaned.
[0067] Exemplarily, the widths of different positions of the first air suction port 202 along the second direction are equal, so as to make full use of the limited space at the front end of the accommodation groove 201 of the device body 200 and ensure the balance of the suction force at different positions in the length direction of the first air suction port 202.
[0068] It should be noted that the length of the first air suction opening 202 in the second direction is much greater than the width of the first air suction opening 202. In the embodiments of the present application, the specific width dimension and length dimension of the first air suction opening 202 are not limited.
[0069] The structure of the second air suction opening 203 will be described in detail below.
[0070] Figure 5 For Figure 3 the partial view at position B in
[0071] Please refer to Figure 5 and in combination with Figures 1 to 3 In a possible implementation manner, the orientation of the first air suction side 203a is perpendicular to the orientation of the second air suction side 203b.
[0072] It can be understood that the different orientations of the first air suction side 203a and the second air suction side 203b can increase the suction area of the second air suction opening 203 and improve the efficiency of the second air suction opening 203 in sucking dust, mites, and fiber hairs. The dust and fiber hairs rolled up by the roller brush assembly 100 can enter the air suction channel 204 from the first air suction side 203a. Since the second air suction side 203b faces the surface to be cleaned, the dust and fiber hairs left on the surface to be cleaned, as well as the dust and fiber hairs that fall back after being lifted by the roller brush assembly 100, can be sucked into the air suction channel 204 from the second air suction side 203b.
[0073] Exemplarily, the cross-sectional shape of the second air suction opening 203 is an "L" - shaped structure, thus forming the first air suction side 203a and the second air suction side 203b.
[0074] It should be noted that the first air suction side 203a and the second air suction side 203b are different orientations of the second air suction opening 203. The dust and fiber hairs sucked from the first air suction side 203a and the second air suction side 203b will converge and then enter the air suction channel 204.
[0075] In some embodiments, there are air guiding walls 2031 on both sides of the second air suction opening 203, and the air guiding walls 2031 extend outward from the second air suction opening 203. The air guiding walls 2031 on both sides can make the outside of the second air suction opening 203 form a flared structure that expands outward towards both ends of the roller brush assembly 100.
[0076] It can be understood that the air guiding walls 2031 can play a guiding role in the suction air flow of the second air suction opening 203, and guide the dust and impurities lifted by the roller brush assembly 100 to flow towards the inside of the air suction channel 204 along with the air flow, preventing the dust and impurities from falling back onto the surface to be cleaned.
[0077] Exemplarily, the air guiding wall 2031 is arranged obliquely with respect to the Y direction, and the value of the inclination angle of the air guiding wall 2031 can be 1°-60°, including but not limited to 1°, 2°, 10°, 30°, 50°, 59°, 60°. The embodiments of the present application do not make specific limitations thereto.
[0078] In some embodiments, the first air suction port 202 faces the bottom side of the device main body 200, and the distance between the first air suction port 202 and the plane where the bottom side of the device main body 200 is located is 10 mm - 15 mm.
[0079] It can be understood that the distance between the first air suction port 202 and the bottom side of the device main body 200 can be approximately the distance between the first air suction port 202 and the surface to be cleaned when the cleaning device 10 is performing a cleaning operation. Controlling the distance between the first air inlet and the bottom side of the device main body 200 within a reasonable range can, on the one hand, prevent the first air suction port 202 from being too close to the surface to be cleaned, so that the airflow is blocked by the sheets or bedding fabrics, and on the other hand, prevent the first air suction port 202 from being too far from the surface to be cleaned, resulting in insufficient suction force for the fiber hairs on the surface to be cleaned.
[0080] Exemplarily, the specific value H of the distance between the first air suction port 202 and the plane where the bottom side of the device main body 200 is located can include but not limited to 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc. The embodiments of the present application do not make specific limitations thereto.
[0081] The specific structure of the device main body 200 will be described in detail below.
[0082] Please refer to Figures 1 to 5 , in a possible implementation manner, the device main body 200 may include a first housing 210, a second housing 220, and a third housing 230. Both the second housing 220 and the third housing 230 are connected to the first housing 210. The second housing 220 is configured to form the first air suction port 202. The third housing 230 is configured to form an air suction channel 204, and the second air suction port 203 is located on the side of the third housing 230 facing the bottom of the device main body 200, thereby improving the convenience of production and assembly of the device main body 200 and reducing production costs.
[0083] It can be understood that the first housing 210 and the second housing 220 can be spliced up and down along the height direction of the device main body 200. The first housing 210 is located above, and the second housing 220 is located below. The second housing 220 can form a receiving groove 201 at the bottom side of the device main body 200 for placing the roller brush assembly 100. The first air suction port 202 is provided at the front edge of the second housing 220 along the X direction.
[0084] The third housing 230 is disposed between the first housing 210 and the second housing 220. The third housing 230 is docked with the first housing 210. On the one hand, the second air suction port 203 formed by the third housing 230 can be opposite to the roller brush assembly 100 in the accommodation groove 201. On the other hand, the air flow sucked in by the first air suction port 202 can enter the air suction channel 204 formed by surrounding the third housing 230.
[0085] In some embodiments, the second housing 220 has an air inlet channel 221. The first air suction port 202 is located at the first end of the air inlet channel 221. A ventilation port 231 is provided on one side of the third housing 230 facing the first housing 210. The second end of the air inlet channel 221 is docked and communicated with the ventilation port 231, so as to ensure the smoothness of the fiber hair sucked in by the first air suction port 202 entering the air suction channel 204 along with the air flow.
[0086] It can be understood that the air flow sucked in by the first air suction port 202 can enter the air suction channel 204 formed by the third housing 230 after bypassing the accommodation groove 201 from above the roller brush assembly 100 through the air inlet channel 221. Exemplarily, the ventilation port 231 and the air inlet channel 221 are hermetically connected. For example, a sealing member such as a rubber ring can be provided between the ventilation port 231 and the air inlet channel 221, or a sealing groove and a sealing protrusion can be provided between the ventilation port 231 and the air inlet channel 221 for cooperation. The embodiments of the present application do not make specific limitations in this regard.
[0087] In some embodiments, the outer wall of the second housing 220 surrounds and forms an accommodation groove 201. The air inlet channel 221 is formed by the housing wall of the first housing 210 surrounding the accommodation groove 201. The cross-sectional contour of the air inlet channel 221 fits around the periphery of the accommodation groove 201, making full use of the structural space on the device main body 200 and improving the compactness of the structure.
[0088] It should be noted that when the first housing 210 and the second housing 220 are docked, they can be fixed by screw connection or ultrasonic welding. The connection position can be positioned by a double stop structure with a protrusion and a groove in cooperation. The edge of the second air suction port 203 of the third housing 230 and the second housing 220 can be fixed by screw connection or ultrasonic welding. The embodiments of the present application do not make specific limitations in this regard.
[0089] The specific structure of the roller brush assembly 100 will be described in detail below.
[0090] Figure 6 It is a schematic structural diagram of the roller brush assembly in the cleaning device provided by the embodiments of the present application.
[0091] Please refer to Figures 1 to 6, As an alternative embodiment, the roller brush assembly 100 may include a roller 110 and a flexible cleaning member 120. The flexible cleaning member 120 is connected to the surface of the roller 110. The diameter of the middle position of the roller 110 along the second direction is smaller than the diameter of the two end positions of the roller 110 along the second direction. The second air suction port 203 is opposite to the middle position of the roller 110 along the second direction.
[0092] It can be understood that the hair rolled up by the roller brush assembly 100 will gather towards the position close to the second air suction port 203 and is more likely to be sucked into the air suction port, rather than becoming more and more tightly wound on the roller brush assembly 100, which is more convenient for cleaning the roller brush assembly 100.
[0093] In some embodiments, the roller 110 may include a first roller body 110a and two second roller bodies 110b. The two second roller bodies 110b are respectively coaxially connected to both ends of the first roller body 110a. The diameter of the first roller body 110a is smaller than or equal to the diameter of the second roller body 110b. The end cap is connected to the end of the second roller body 110b facing away from the first roller body 110a.
[0094] It can be understood that the first roller body 110a is between the two second roller bodies 110b and the three are coaxially arranged, which can make the roller 110 have a structure that is wide at both ends and narrow in the middle. When the roller brush assembly 100 rolls up the hair, the hair can gather towards the middle of the roller brush assembly 100, avoiding the hair from winding around the two ends of the roller brush assembly 100.
[0095] Exemplarily, the diameters of both ends of the first roller body 110a along the Y direction may be larger than the diameter of the middle position of the first roller body 110a. For example, the diameter of the first roller body 110a may gradually decrease from both ends to the middle. When the roller brush assembly 100 rolls, the hair rolled up by the roller brush assembly 100 will gather towards the middle. The hair gathering towards the middle can improve the efficiency of the hair being sucked into the cleaning device 10 and avoid the hair from continuously winding and tightening on the roller brush assembly 100.
[0096] Exemplarily, the side wall of the first roller body 110a may be an arc surface that narrows from both ends to the middle, or the side wall of the first roller body 110a may be an inclined surface that narrows from both ends to the middle. The embodiments of the present application do not make specific limitations on this.
[0097] Exemplarily, the diameters of the two second roller bodies 110b may be equal along the Y direction. The diameter of the second roller body 110b may be equal to the diameter of the end position of the first roller body 110a along the Y direction.
[0098] Exemplarily, the first roller body 110a and the two second roller bodies 110b are an integrally formed structure.
[0099] In some embodiments, the flexible cleaning member 120 may include a first rubber strip portion 120a and two second rubber strip portions 120b. The two second rubber strip portions 120b are respectively connected to two ends of the first rubber strip portion 120a. The height of the second rubber strip portion 120b along the radial direction of the roller 110 is greater than the height of the first rubber strip portion 120a along the radial direction of the roller 110. The groove is located at the end of the second rubber strip portion 120b facing away from the first rubber strip portion 120a.
[0100] It can be understood that the height of the flexible cleaning member 120 is higher at both axial ends of the roller 110, and it narrows at the middle position of the axial direction of the roller 110. Hairs can gather towards the middle of the roller brush assembly 100, avoiding the entanglement of hairs around both ends of the roller brush assembly 100.
[0101] Exemplarily, the first rubber strip portion 120a faces the first roller 110a, and the two second rubber strip portions 120b face the two second rollers 110b respectively. Wherein, the second rubber strip portion 120b can be arranged to protrude from the surface of the second roller 110b; the first rubber strip portion 120a can protrude from the surface of the first roller 110a, or the first rubber strip portion 120a can be lower than the surface of the first roller 110a, while maintaining a good cleaning effect, reducing the amount of hairs wound around the roller brush assembly 100.
[0102] Exemplarily, when the number of the flexible cleaning members 120 is multiple, at least one flexible cleaning member 120 protrudes from the surface of the first roller 110a. In this way, it is ensured that at the position opposite to the first roller 110a, there is a flexible cleaning member 120 that can slap the surface to be cleaned when the roller brush assembly 100 rotates.
[0103] It should be noted that the lengths of the first rubber strip portion 120a and the first roller 110a along the Y direction are equal, and the lengths of the second rubber strip portion 120b and the second roller 110b along the Y direction are equal. The embodiments of the present application do not limit the specific length dimensions of the first roller 110a and the second roller 110b, as well as the first rubber strip portion 120a and the second rubber strip portion 120b.
[0104] The embodiment of the present application provides a cleaning device, including a device main body and a roller brush assembly. The device main body has a receiving groove, and the roller brush assembly is rotatably arranged in the receiving groove. The device main body is provided with a first air suction port at the front end of the receiving groove along a first direction, and the device main body is provided with a second air suction port at the rear end of the receiving groove along the first direction; the device main body has an air suction channel, and both the first air suction port and the second air suction port are communicated with the air suction channel. During the cleaning process, the air suction port at the front end can suck away some hair fibers first, and the remaining hairs lifted by the roller brush assembly can be sucked away by the air suction port at the rear end, thereby avoiding the entanglement and knotting of a large amount of hair fibers lifted by the rolling of the roller brush assembly and improving the cleaning efficiency.
[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
