Description

Technical Field

[0001] The present application relates to the technical field of cleaning products, and in particular to a roller brush assembly and a cleaning device. Background Art

[0002] Mite removers, vacuum cleaners, and robot vacuums are commonly used cleaning devices in the home. Vacuum cleaners and robot vacuums can clean floors, while mite removers can remove dust and worms from surfaces like mattresses and leather.

[0003] In related technologies, 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.

[0004] However, during the cleaning process of current cleaning devices, hair is easily entangled at both ends of the roller brush and cannot be sucked into the interior of the device. Utility Model Content

[0005] The present application provides a roller brush assembly and a cleaning device to solve the technical problem that hair is easily entangled at both ends of the roller brush during the cleaning process of current cleaning devices and cannot be sucked into the interior of the device.

[0006] In the first aspect, the present application provides a roller brush assembly, which includes a roller, a flexible cleaning member and an end cover; the flexible cleaning member is connected to the side wall of the roller; the flexible cleaning member is configured to extend from the first axial end of the roller to the second axial end of the roller; and the end cover is connected to the axial end of the roller.

[0007] One end of the flexible cleaning piece facing the end cover is provided with a groove, and the end cover has a convex portion facing the flexible cleaning piece, and the convex portion is inserted into the groove.

[0008] The roller brush assembly provided in the embodiment of the present application is provided with a groove at one end where the flexible cleaning member and the end cover cooperate, and a protrusion is provided on the end cover, so that part of the structure of the end cover can be embedded in the flexible cleaning member, thereby preventing the hair rolled up by the roller brush assembly from entering between the end cover and the flexible cleaning member, preventing the hair from becoming more and more entangled at both ends of the roller brush assembly as it rotates, and improving the cleaning convenience of the roller brush assembly.

[0009] As an optional embodiment, the raised portion is arranged around the circumferential edge of the end cover, and the raised portion is arranged to form an accommodating groove, and the end portion of the flexible cleaning member is at least partially located in the accommodating groove.

[0010] With this arrangement, the structures of the flexible cleaning member and the end cover can be embedded in each other, thereby better preventing hair from being entangled.

[0011] As an optional embodiment, there may be multiple flexible cleaning members, which are spaced apart along the circumference of the drum; the grooves of the multiple flexible cleaning members are respectively inserted into different positions of the protrusion along the circumference of the end cover.

[0012] With such arrangement, the roller brush assembly can have a better cleaning effect, and at the same time, during the rotation of the roller brush assembly, hair can be prevented from being entangled to the end at different circumferential positions thereof.

[0013] As an optional embodiment, the distance between the outer edge of the protrusion facing the end of the flexible cleaning member and the axis of the drum is greater than the distance between the outer edge of the end of the end cover facing away from the flexible cleaning member and the axis of the drum.

[0014] With this arrangement, when the hair is rolled up at the end of the roller brush assembly, the hair can slide along the outer wall of the end cover toward the axial outside of the roller brush assembly, so that the hair is away from the gap between the end cover and the flexible cleaning member.

[0015] As an optional embodiment, the side of the raised portion facing the roller axis abuts against the wall of the groove; this arrangement allows the end cap to limit the position of the flexible cleaning element. Alternatively, the side of the raised portion facing away from the roller axis provides a gap with the wall of the groove; this arrangement provides margin for error during assembly of the end cap and the soft cleaning element, preventing interference between the two.

[0016] As an optional embodiment, there are two end covers, which are respectively connected to the two ends of the roller along the axial direction; grooves are provided at both ends of the flexible cleaning member in the length direction, and the protrusions of the two end covers are respectively plugged into the grooves at both ends of the flexible cleaning member.

[0017] With such an arrangement, hair can be prevented from being entangled at both ends of the axial direction of the roller.

[0018] As an optional embodiment, the drum has a center hole, which is coaxially arranged with the rotation axis of the drum; the end cover has an inserting portion facing the drum, which is inserted into the center hole.

[0019] Such an arrangement can improve the assembly reliability of the end cover and, in addition, can ensure the assembly accuracy of the coaxial arrangement of the end cover and the roller.

[0020] As an optional embodiment, the roller may include a first roller and two second rollers, the two second rollers are coaxially connected to the two ends of the first roller, the diameter of the first roller is less than or equal to the diameter of the second roller; the end cover is connected to the end of the second roller away from the first roller.

[0021] Such a configuration can make the roller have a structure that is wide at both ends and narrow in the middle. When the roller brush assembly rolls up the hair, the hair can gather toward the middle of the roller brush assembly, preventing the hair from being entangled at both ends of the roller brush assembly.

[0022] As an optional embodiment, the flexible cleaning member may include a first rubber strip portion and two second rubber strip portions, the two second rubber strip portions are respectively connected to the two ends of the first rubber strip portion; the height of the second rubber strip portion along the radial direction of the roller is greater than the height of the first rubber strip portion along the radial direction of the roller; the groove is located at the end of the second rubber strip portion away from the first rubber strip portion.

[0023] This arrangement allows the flexible cleaning element to be higher at both ends of the roller axis and narrower in the middle of the roller axis, so that the hair can gather toward the middle of the roller brush assembly to prevent the hair from being entangled at both ends of the roller brush assembly.

[0024] In a second aspect, the present application provides a cleaning device, which includes a device body and a roller brush assembly in the above technical solution, and the roller brush assembly is rotatably arranged on the device body.

[0025] The present application provides a roller brush assembly and a cleaning device, wherein the roller brush assembly includes a roller, a flexible cleaning member and an end cover; the flexible cleaning member is connected to the side wall of the roller; the flexible cleaning member is configured to extend from a first end in the axial direction of the roller to a second end in the axial direction of the roller; the end cover is connected to the end portion in the axial direction of the roller, and the flexible cleaning member is provided with a groove at one end facing the end cover, and the end cover has a protrusion facing the flexible cleaning member, and the protrusion is inserted in the groove so that part of the structure of the end cover can be embedded in the flexible cleaning member, thereby preventing hair rolled up by the roller brush assembly from entering between the end cover and the flexible cleaning member, preventing the hair from becoming more and more entangled at both ends of the roller brush assembly as it rotates, and improving the cleaning convenience of the roller brush assembly.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 gaps in the end caps, making cleaning the brush time-consuming and laborious.

[0044] In order to solve the above technical problems, the embodiments of the present application provide a roller brush assembly and a cleaning device, which is used in the cleaning device. Through the matching structure design of the end cover and the soft cleaning part of the roller brush assembly, the structure of the end cover can be embedded in the soft cleaning part, and a stop structure is formed between the end cover and the flexible cleaning part to prevent hair from being entangled and entering the gap between the end cover and the flexible cleaning part when the end of the roller brush assembly is rolled up, so that the hair can be sucked into the interior of the cleaning device.

[0045] Figure 1 A schematic structural diagram of a roller brush assembly provided in an embodiment of the present application; Figure 2 for Figure 1 Cross-sectional view in the AA direction; Figure 3 for Figure 2 Partial view of position B in the middle; Figure 4A schematic structural diagram of a flexible cleaning member in a roller brush assembly provided in an embodiment of the present application; Figure 5 A schematic diagram of the structure of the cleaning equipment provided in an embodiment of the present application.

[0046] See also Figures 1 to 5 As shown, the present application provides a roller brush assembly 100, which includes a roller 110, a flexible cleaning member 120, and an end cap 130. The flexible cleaning member 120 is connected to the side wall of the roller 110, and the end cap 130 is connected to the axial end of the roller 110. When the roller brush assembly 100 is applied to the cleaning device 10, the roller brush assembly 100 can rotate as a whole around the axial direction of the roller 110.

[0047] The flexible cleaning member 120 is configured to extend from a first axial end of the roller 110 to a second axial end of the roller 110. During the cleaning operation, the roller 110 serves as the main structure of the roller brush assembly 100 to support the roller 110, and the flexible cleaning member 120 can contact the surface to be cleaned. The flexible cleaning member 120 can produce elastic deformation, and the flexible cleaning member 120 can rub and tap 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.

[0048] In some embodiments, a groove 121 is provided at one end of the flexible cleaning member 120 facing the end cap 130, and the end cap 130 has a protrusion 131 facing the flexible cleaning member 120, which is inserted into the groove 121. In this way, part of the structure of the end cap 130 can be embedded in the flexible cleaning member 120 along the axial direction of the drum 110.

[0049] It is understood that the flexible cleaning member 120 is protruding from the surface of the drum 110, and the end cap 130 is blocked at the end of the flexible cleaning member 120 along the axial direction of the drum 110, and the diameter of the end cap 130 is larger than the diameter of the drum 110. The flexible cleaning member 120 and the end cap 130 form a stop structure through the cooperation between the groove 121 and the protrusion 131. 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.

[0050] 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.

[0051] In the embodiment of the present application, the flexible cleaning member 120 can be installed on the drum 110 by plugging along the axial direction of the drum 110. After the flexible cleaning member 120 is installed, end caps 130 are respectively installed at both ends of the axial direction of the drum 110. The end caps 130 can limit the flexible cleaning member 120 along the axial direction of the drum 110.

[0052] For example, the radial cross-section of the drum 110 can be circular, and the end cap 130 can be circular in shape. The end cap 130 can be coaxially arranged with the drum 110, and the coverage area of the end cap 130 is larger than the axial end area of the drum 110, so as to prevent hair from being caught in the rollers at both ends of the drum 110.

[0053] Please continue to refer to Figures 1 to 5 In some embodiments, the raised portion 131 is disposed around the circumferential edge of the end cover 130 , and the raised portion 131 is disposed to form a receiving groove, and the end portion of the flexible cleaning member 120 is at least partially located in the receiving groove.

[0054] It is understood that the raised portion 131 forms an annular structure on the circumferential edge of the end cap 130. The raised portion 131 and the groove 121 form a first stop structure, and the accommodating groove and the end of the flexible cleaning member 120 form a second stop structure, so that the structures of the flexible cleaning member 120 and the end cap 130 can be embedded in each other. Therefore, hair rolled up by the roller brush assembly 100 needs to pass through multiple stop structures to enter the gap between the end cap 130 and the flexible cleaning member 120, which better prevents the hair from being entangled.

[0055] 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.

[0056] In some embodiments, there may be multiple flexible cleaning members 120, each of which is spaced apart along the circumference of the drum 110. The grooves 121 of the multiple flexible cleaning members 120 are respectively inserted into the raised portions 131 at different positions along the circumference of the end cap 130. Thus, during the cleaning process of the roller brush assembly 100, the multiple flexible cleaning members 120 can sequentially strike the surface to be cleaned as the roller brush assembly 100 rotates, resulting in a better cleaning effect.

[0057] It can be understood that during the rotation of the roller brush assembly 100, different flexible cleaning members 120 can respectively form a stop structure with the raised portion 131 of the end cover 130 at different circumferential positions of the end of the roller brush assembly 100, thereby preventing hair from being entangled in the gap between the end cover 130 and the flexible cleaning member 120 during the continuous rotation of the roller brush assembly 100.

[0058] For example, multiple flexible cleaning members 120 are arranged in parallel and extend along the axial direction of the roller 110. In this way, the flexible cleaning members 120 can contact the cleaned surface in the axial direction of the roller brush assembly 100, thereby increasing the cleaning range.

[0059] For example, the plurality of flexible cleaning members 120 can spirally extend in the same direction along the circumferential outer wall of the roller 110. In this way, when the roller brush assembly 100 rolls along the cleaning direction of the cleaning device 10, different positions of the flexible cleaning members 120 in the extending direction can sequentially contact the surface to be cleaned as the roller brush assembly 100 rolls, thereby improving the efficiency of sucking dust and hair.

[0060] It should be noted that the number of the flexible cleaning members 120 may be two, three, four, five or more, and this embodiment of the present application does not impose any specific limitation thereto.

[0061] In some embodiments, the distance between the outer edge of the protrusion 131 at the end facing the flexible cleaning member 120 and the axis of the drum 110 is greater than the distance between the outer edge of the end of the end cap 130 facing away from the flexible cleaning member 120 and the axis of the drum 110. Thus, when the end cap 130 rotates with the drum 110, the outer diameter of the protrusion 131 at the end facing the flexible cleaning member 120 in the rotating body formed by the end cap 130 is greater than the outer diameter of the end of the end cap 130 facing away from the flexible cleaning member 120.

[0062] It is understood that, with the axial cross-section of the roller brush assembly 100 as a reference, the end cap 130 is arranged to be inclined relative to the axial direction of the drum 110. When the hair is rolled up at the end of the roller brush assembly 100, the hair can slide along the outer wall of the end cap 130 toward the axial outside of the roller brush assembly 100, thereby keeping the hair away from the gap between the end cap 130 and the flexible cleaning member 120.

[0063] For example, the outer diameter of the protrusion 131 at the end facing the flexible cleaning member 120 is D1, and the outer diameter of the end cap 130 at the end facing away from the flexible cleaning member 120 is D2, where D1>D2. The outer diameter of the roller brush assembly 100 is D0, which refers to the diameter of the radial cross-section of the rotating body formed when the roller brush assembly 100 rotates about its axial direction, that is, the outer diameter formed by the outer edge of the flexible cleaning member 120 when the roller brush assembly 100 rotates about its axial direction, wherein D0>D1.

[0064] In some embodiments, the side of the protrusion 131 facing the axis of the drum 110 abuts against the groove wall of the groove 121 , so that the end cover 130 can limit the flexible cleaning member 120 .

[0065] In some embodiments, a gap is formed between the side of the protrusion 131 facing away from the axis of the drum 110 and the wall of the groove 121, thereby providing error redundancy for the assembly of the end cover 130 and the soft cleaning member to avoid interference between the two.

[0066] It should be noted that the thickness of the protrusion 131 can be smaller than the width of the groove 121, and the protrusion 131 and the groove 121 are plugged in with a clearance fit. The embodiment of the present application does not limit the specific value of the gap size tolerance between the protrusion 131 and the groove wall of the groove 121.

[0067] In some embodiments, there are two end caps 130, each of which is connected to the two axial ends of the drum 110. Grooves 121 are provided at both ends of the flexible cleaning member 120 in the longitudinal direction, and the protrusions 131 of the two end caps 130 are respectively plugged into the grooves 121 at both ends of the flexible cleaning member 120, thereby preventing hair from being entangled at both axial ends of the drum 110.

[0068] It should be noted that the two end covers 130 at the axial ends of the drum 110 cooperate with the two ends of the flexible cleaning member 120 in the same manner, which will not be described in detail here.

[0069] In some embodiments, the drum 110 has a central hole 111, which is coaxially arranged with the rotation axis of the drum 110. The end cap 130 has an inserting portion 132 facing the drum 110, and the inserting portion 132 is inserted into the central hole 111, thereby improving the assembly reliability of the end cap 130 and ensuring the assembly accuracy of the coaxial arrangement of the end cap 130 and the drum 110.

[0070] It is understood that the center hole 111 can pass through both ends of the drum 110 along the axial direction of the drum 110. The plug-in portion 132 and the center hole 111 can be assembled using an interference fit. When the plug-in portion 132 is inserted into the center hole 111, the end of the drum 110 can abut against the end cover 130.

[0071] The structure of the drum 110 will be described in detail below.

[0072] Please continue to refer to Figures 1 to 5 In one possible implementation, the drum 110 may include a first roller 110a and two second rollers 110b. The two second rollers 110b are coaxially connected to the ends of the first roller 110a. 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.

[0073] It can be understood that the first roller 110a is between the two second rollers 110b, and the three are coaxially arranged, so that the roller 110 has 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 toward the middle of the roller brush assembly 100, avoiding the hair from being entangled at the two ends of the roller brush assembly 100.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] Exemplarily, the first roller 110a and the two second rollers 110b are an integrally formed structure.

[0079] In some embodiments, the flexible cleaning member 120 may include a first rubber strip portion 120a and two second rubber strip portions 120b, with the two second rubber strip portions 120b connected to both ends of the first rubber strip portion 120a. The height of the second rubber strip portions 120b along the radial direction of the drum 110 is greater than the height of the first rubber strip portion 120a along the radial direction of the drum 110. The groove 121 is located at the end of the second rubber strip portion 120b facing away from the first rubber strip portion 120a.

[0080] It is understandable that 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.

[0081] For example, the first rubber strip portion 120a is opposite to the first roller 110a, and the two second rubber strip portions 120b are opposite to the two second rollers 110b, respectively. 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, thereby maintaining a good cleaning effect while reducing the amount of hair entangled in the roller brush assembly 100.

[0082] Exemplarily, when there are multiple flexible cleaning members 120, at least one flexible cleaning member 120 protrudes from the surface of the first roller 110a, so that a flexible cleaning member 120 is ensured to be located relative to the first roller 110a and can hit the surface to be cleaned when the roller brush assembly 100 rotates.

[0083] It should be noted that the lengths of the first rubber strip portion 120a and the first roller 110a along the X direction are equal, and the lengths of the second rubber strip portion 120b and the second roller 110b along the X direction are equal. The embodiment of the present application does not limit the specific length dimensions of the first roller 110a and the second roller 110b, and the first rubber strip portion 120a and the second rubber strip portion 120b.

[0084] Please refer to Figure 5 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, and the roller brush assembly 100 is rotatably arranged on the device body 200.

[0085] 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.
