[0041] The terms "first," "second," and "third" (if any) in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the application described herein can, for example, be implemented in orders other than those illustrated or described herein.

[0042] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or service tool that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or service tool.

[0043] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] Cleaning equipment usually includes a shell and a fan unit arranged in the shell. The airflow generated by the fan unit generates suction at the suction port of the shell. A roller brush can be provided at the position corresponding to the suction port. The roller brush rolls on the cleaned surface to pick up dust and hair, and the dust and hair are sucked into the inside of the device through the suction force of the suction port to achieve the cleaning function.

[0045] However, during the cleaning process, hair can easily get tangled in the brush of current cleaning equipment, preventing it from being sucked into the device. For example, a mite remover can remove dust and worms from surfaces like mattresses and leather. Mattresses are often clinging to a lot of hair, and as the brush rolls across the mattress, the hair can easily get tangled in the brush. As the brush rolls, the tangled hair becomes increasingly entangled toward the ends of the brush, preventing it from being sucked away. Furthermore, when cleaning the brush after cleaning, the hair can easily get tangled and stuck in the gap between the rotating shafts at the ends of the brush, making cleaning the brush time-consuming and labor-intensive.

[0047] See also Figures 1 to 6 As shown, the present application provides a roller brush assembly 100, which includes a roller 110, a flexible cleaning member 120, an end cap 130 and a roller brush shaft 140. The flexible cleaning member 120 is connected to the side wall of the roller 110. The end cap 130 is connected to the axial end of the roller 110. The roller brush shaft 140 is rotatably connected to the end cap 130. When the roller brush assembly 100 is applied to the cleaning device 10, the roller brush shaft 140 plays a supporting role, and the roller 110, the flexible cleaning member 120, and the end cap 130 can rotate around the roller brush shaft 140 as a whole.

[0048] The roller brush shaft 140 includes a rotating shaft 141 and a support portion 142. The end cap 130 has a through hole 131, and the rotating shaft 141 is inserted into the through hole 131. The support portion 142 is connected to the rotating shaft 141 and is located on the side of the end cap 130 facing away from the drum 110. The side of the end cap 130 facing away from the drum 110 is provided with a first groove 132. The support portion 142 is connected to an inserting portion 143 facing the end cap 130, and the inserting portion 143 is inserted into the first groove 132.

[0049] It can be understood that the diameter of the end cover 130 is larger than the diameter of the roller brush shaft 140. Since the end cover 130 and the roller brush shaft 140 are rotatably connected, if fiber hair enters between the end cover 130 and the roller brush shaft 140, it will become more and more entangled with the relative rotation of the end cover 130 and the roller brush shaft 140 and cannot be cleaned. Therefore, in the embodiment of the present application, the end cover 130 cooperates with the plug-in portion 143 of the roller brush shaft 140 through the first groove 132 to form a stop structure. When the roller brush assembly 100 rotates to roll up the hair, it can prevent the hair from entering the gap between the end cover 130 and the roller brush shaft 140.

[0050] It should be noted that, in the roller brush assembly 100 provided in the embodiment of the present application, a first groove 132 is provided on the end cover 130 to cooperate with the plug-in portion 143 of the roller brush shaft 140, so that part of the structure of the roller brush shaft 140 can be embedded in the end cover 130, thereby preventing the hair rolled up by the roller brush assembly 100 from entering between the end cover 130 and the roller brush shaft 140, and preventing the hair from becoming more and more tightly entangled on the roller brush shaft 140 as the roller brush assembly 100 rotates.

[0051] When the cleaning device 10 completes the cleaning operation, since the hair is not entangled between the end cover 130 and the roller brush shaft 140 , there is no need to disassemble the end cover 130 and the roller brush shaft 140 when cleaning the roller brush assembly 100 , thereby improving the cleaning convenience of the roller brush assembly 100 .

[0052] Please continue to refer to Figures 1 to 6 In some embodiments, the roller 110, the end cap 130, and the roller brush shaft 140 are coaxially arranged. This allows the center of gravity of the roller brush assembly 100 to be colinear with the axes of the roller 110, the end cap 130, and the roller brush shaft 140, enabling the roller 110 and the end cap 130 to rotate smoothly relative to the roller brush shaft 140.

[0053] It should be noted that the roller 110 is provided with end covers 130 at both ends along the circumferential axis, wherein the end cover 130 at one end is rotatably connected to the roller brush shaft 140, or the end covers 130 at both ends are rotatably connected to the roller brush shaft 140. This embodiment of the present application does not make any specific limitation on this.

[0054] In some embodiments, the first groove 132 is disposed axially around the end cap 130 , and the plug portion 143 extends along a circumferential edge of the support portion 142 . The shape of the first groove 132 matches the shape of the plug portion 143 .

[0055] It is understood that the first groove 132 is an annular groove axially disposed around the end cap 130, with its center coaxial with the axis of the end cap 130. The plug-in portion 143 is an annular protrusion circumferentially surrounding the edge of the support portion 142, and the plug-in portion 143 is coaxial with the axis of the roller brush shaft 140. The end cap 130 and the roller brush shaft 140 can form an annular structure that is mutually embedded. When the drum 110 rotates, the plug-in portion 143 rotates relative to the first groove 132, and during the rotation along the first groove 132, interference between the end cap 130 and the roller brush shaft 140 can be prevented.

[0056] For example, the first groove 132 and the plug-in portion 143 can be plugged in with a clearance fit to prevent interference between the plug-in portion 143 and the end cap 130 due to dimensional errors. The embodiment of the present application does not specifically limit the width of the first groove 132 and the thickness of the plug-in portion 143.

[0057] For example, the plug-in portion 143, the shaft 141, and the support portion 142 can be integrally formed. The shaft 141 is coaxially inserted into the through hole 131 of the end cover 130, the support portion 142 is blocked at the end of the end cover 130, and the plug-in portion 143 is plugged into the first groove 132 of the end cover 130 to form a stop structure.

[0058] In some embodiments, a first retaining rib 133 and a second retaining rib 134 are provided on the side of the end cover 130 facing away from the drum 110 . The first retaining rib 133 and the second retaining rib 134 are coaxially arranged around the axial direction of the end cover 130 , and the first retaining rib 133 and the second retaining rib 134 are surrounded to form a first groove 132 .

[0059] It is understood that both the first retaining rib 133 and the second retaining rib 134 protrude from one side of the end cover 130 in a direction away from the drum 110. The first retaining rib 133 and the second retaining rib 134 are coaxially arranged with the axis of the end cover 130. The diameter of the first retaining rib 133 is larger than the diameter of the second retaining rib 134. The first retaining rib 133 is disposed circumferentially around the outer side of the second retaining rib 134, and the gap between the first retaining rib 133 and the second retaining rib 134 forms a first groove 132.

[0060] Exemplarily, the first retaining rib 133 and the second retaining rib 134 can enable the end cover 130 and the roller brush shaft 140 to directly form a double stop structure, wherein the first retaining rib 133 serves as the first stop, the plug-in portion 143 serves as the second stop, and the second retaining rib 134 serves as the structure inside the double stop structure, thereby better preventing hair from being entangled.

[0061] In some embodiments, the first retaining rib 133 is located on the circumferential outside of the second retaining rib 134, and the height dimension of the first retaining rib 133 along the axial direction of the end cover 130 is greater than the height dimension of the second retaining rib 134 along the axial direction of the end cover 130, thereby preventing fiber hair from slipping between the first retaining rib 133 and the plug-in portion 143.

[0062] It is understandable that the larger height dimension of the first rib 133 can make the radial projection of the first rib 133 in the roller brush assembly 100 have a larger overlapping area with the plug-in portion 143, making it more difficult for fiber hair to bypass the first rib 133 and enter the first groove 132.

[0063] For example, the end of the first retaining rib 133 may be flush with the root end surface of the plug portion 143. The embodiment of the present application does not specifically limit the height values of the first retaining rib 133 and the second retaining rib 134 along the axial direction of the end cover 130.

[0064] In some embodiments, the second retaining rib 134 is arranged to form a second groove 135. The roller brush assembly 100 may further include a bearing 150, which is sleeved on the outer side of the rotating shaft 141 and located in the second groove 135. The inner ring of the bearing 150 abuts against the outer wall of the rotating shaft 141, and the outer ring of the bearing 150 abuts against the groove wall of the second groove 135, thereby improving the relative rotation smoothness of the end cap 130 and the roller brush shaft 140.

[0065] In some embodiments, the roller 110 has a central hole 111 that extends through both ends of the roller 110 in the axial direction. The end cap 130 is at least partially inserted into the central hole 111 at one end facing the roller 110. The roller brush assembly 100 further includes a sleeve 160 that is sleeved on the outside of the rotating shaft 141. The sleeve 160 is positioned in the central hole 111 on the side of the end cap 130 that faces away from the support portion 142, thereby axially limiting the roller brush shaft 140 and the end cap 130 and preventing the roller brush shaft 140 from axially shifting.

[0066] For example, the roller brush assembly 100 may further include a collar 170. An annular groove is provided on the outer wall of the rotating shaft 141. The collar 170 is sleeved in the annular groove. The collar 170 at least partially protrudes outside the annular groove and is blocked on the side of the sleeve 160 facing away from the end cover 130. The collar 170 can limit the sleeve 160 so that the sleeve 160 and the end cover 130 remain in contact.

[0067] Please continue to refer to Figures 1 to 6 In one possible implementation, the flexible cleaning member 120 is configured to extend from a first axial end of the drum 110 to a second axial end of the drum 110. A third groove 121 is defined at one end of the flexible cleaning member 120 that faces the end cap 130. The end cap 130 includes a protrusion 136 that faces the flexible cleaning member 120. The protrusion 136 is inserted into the third groove 121, thereby preventing hair rolled up by the roller brush assembly 100 from entering between the end cap 130 and the flexible cleaning member 120.

[0068] It can be understood that during the cleaning operation, the roller 110 plays a supporting role as the main structure of the roller brush assembly 100, the flexible cleaning member 120 can contact the surface to be cleaned, and the flexible cleaning member 120 can produce elastic deformation. The flexible cleaning member 120 rubs and pats the surface to be cleaned to bring up dust, mites and hair, so that the dust, mites and hair can be sucked into the interior of the cleaning device 10.

[0069] The flexible cleaning member 120 protrudes from the surface of the drum 110, and the end cap 130 is disposed at the end of the flexible cleaning member 120 along the axial direction of the drum 110. The diameter of the end cap 130 is larger than the diameter of the drum 110. The third groove 121 and the protrusion 136 cooperate to form a stop structure between the flexible cleaning member 120 and the end cap 130. When the roller brush assembly 100 rotates to roll up hair, it can prevent hair from entering the gap between the end cap 130 and the flexible cleaning member 120, thereby preventing hair from being entangled on the drum 110 at the end of the roller brush assembly 100.

[0070] For example, the flexible cleaning member 120 can be a rubber strip, a brush, or a combination thereof. For example, the flexible cleaning member 120 can be a rubber strip. When a colloid is used as the flexible cleaning member 120, the rubber strip can pat the surface to be cleaned, and hair will not be entangled in the rubber strip. Hair picked up by the rubber strip is more easily sucked into the interior of the cleaning device 10 along the outer edge of the colloid.

[0071] It should be noted that in the roller brush assembly 100 provided in the embodiment of the present application, part of the structure of the end cap 130 can be embedded in the flexible cleaning member 120, so that at the end of the flexible cleaning member 120, the projections of the flexible cleaning member 120 and the end cap 130 along the radial direction of the drum 110 can partially overlap, and hair will not slip into the gap between the flexible cleaning member 120 and the end cap 130, thereby preventing the hair from becoming increasingly entangled at both ends of the roller brush assembly 100 as it rotates. When the cleaning operation of the cleaning device 10 is completed, since the hair is not entangled between the end cap 130 and the flexible cleaning member 120, there is no need to remove the end cap 130 when cleaning the roller brush assembly 100, thereby improving the cleaning convenience of the roller brush assembly 100.

[0072] Please continue to refer to Figures 1 to 6 The present application provides a cleaning device 10, which includes a device body 200 and a roller brush assembly 100 in the above technical solution. The device body 200 has a receiving groove 201, and the roller brush assembly 100 is rotatably arranged in the receiving groove 201.

[0073] When the cleaning device 10 performs a cleaning operation, the side of the device 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 body 200 moves, the roller brush assembly 100 rolls on the surface to be cleaned. The roller brush assembly 100 can bring up dust, mites, hair and other impurities on the surface to be cleaned, making it easier for dust, mites, hair and other impurities to be sucked into the inside of the device body 200.

[0074] It is understood that the device body 200 is provided with an air suction port, which is opposite to the roller brush assembly 100 and communicates with the air suction channel in the device body 200. The device body 200 is provided with a fan and a dust collection component. The fan is used to generate airflow in the air suction channel to generate suction at the air suction port. The dust, mites, and fiber hair sucked in are stored in the dust collection component. The dust collection component is detachably connected to the device body 200 for easy cleaning.

[0075] In some embodiments, the drum 110 may include a first roller 110a and two second rollers 110b, wherein the two second rollers 110b are coaxially connected to the ends of the first roller 110a, and the diameter of the first roller 110a is less than or equal to the diameter of the second roller 110b. The end cap 130 is connected to the end of the second roller 110b facing away from the first roller 110a.

[0076] It is understood that the first roller 110a is coaxially disposed between the two second rollers 110b, giving the roller 110 a structure that is wider at both ends and narrower in the middle. The air intake can be opposite the first roller 110a located in the middle. When the roller brush assembly 100 rolls up hair, the hair can be gathered toward the middle of the roller brush assembly 100, preventing the hair from being entangled at the ends of the roller brush assembly 100.

[0077] The axial direction of the drum 110 is defined as the X direction, and the radial direction of the drum 110 is defined as the Y direction.

[0078] For example, the diameter of the first roller 110a at both ends along the X-direction can be larger than the diameter at the center of the first roller 110a. For example, the diameter of the first roller 110a can gradually decrease from both ends toward the center. As the roller brush assembly 100 rolls, hair caught by the roller brush assembly 100 will gather toward the center. This gathering of hair toward the center can improve the efficiency of hair suction by the cleaning device 10 and prevent hair from becoming continuously entangled and tightened around the roller brush assembly 100.

[0079] For example, the sidewall of the first roller 110a may be an arcuate surface narrowing from both ends to the middle, or the sidewall of the first roller 110a may be an inclined surface narrowing from both ends to the middle, which is not specifically limited in the embodiment of the present application.

[0080] For example, the diameters of the two second rollers 110 b may be kept equal along the X direction. The diameter of the second roller 110 b may be equal to the diameter of the end position of the first roller 110 a along the X direction.

[0081] Exemplarily, the first roller 110a and the two second rollers 110b are an integrally formed structure.

[0082] In some embodiments, the flexible cleaning member 120 is higher at both axial ends of the roller 110 and narrows at the axial middle portion of the roller 110, so that the hair can gather toward the middle of the roller brush assembly 100 to prevent the hair from being entangled at both ends of the roller brush assembly 100.

[0083] For example, the narrowed portion of the flexible cleaning member 120 is opposite to the first roller 110a, so that the diameter of the rotating body formed by the rotation of the roller brush assembly 100 is smaller in the middle position along the axial direction, so that the rotating diameter of the roller brush assembly 100 in the area opposite to the air suction port is smaller, and fiber hair is more easily gathered in the middle and sucked into the air suction port.

[0084] It should be noted that when there are multiple flexible cleaning members 120, at least one flexible cleaning member 120 protrudes from the surface of the first roller 110a. In this way, it is ensured that there is a flexible cleaning member 120 at a position relative to the first roller 110a that can hit the surface to be cleaned when the roller brush assembly 100 rotates.

[0085] The following is an example of an application scenario of the cleaning device 10 provided in the embodiment of the present application.

[0086] The cleaning device 10 provided in the embodiment of the present application is a cleaning tool with a roller brush structure. Specifically, the product types of the cleaning device 10 in the embodiment of the present application may include but are not limited to a mite remover, a vacuum cleaner, a sweeper, a sweeping robot, etc. Depending on the product type, the cleaning device 10 provided in the embodiment of the present application can be used to clean the floor, clothes, bedding, sofa furniture, etc., and the embodiment of the present application does not make specific limitations on this.

[0087] The present invention provides a roller brush assembly and cleaning device. The roller brush assembly includes a roller, a flexible cleaning member, an end cap, and a roller brush shaft. The flexible cleaning member is connected to the side wall of the roller. The end cap is connected to the axial end of the roller. The roller brush shaft is rotatably connected to the end cap. The roller brush shaft includes a rotating shaft and a support portion. The end cap has a through hole, and the rotating shaft is inserted into the through hole. The support portion is connected to the rotating shaft and is located on the side of the end cap facing away from the roller. The side of the end cap facing away from the roller is provided with a first groove. The support portion is connected to the plug portion facing the end cap, and the plug portion is inserted into the first groove. This prevents hair rolled up by the roller brush assembly from entering between the end cap and the roller brush shaft, preventing the hair from becoming entangled at both ends of the roller brush assembly as it rotates, thereby improving the cleaning convenience of the roller brush assembly.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
