Description

Technical Field

[0001] The utility model relates to the technical field of floor brushes, in particular to a cleaning floor brush and a vacuum cleaner. Background Art

[0002] At present, vacuum cleaners usually use electric floor brushes, which are conducive to capturing debris particles on the ground into the suction pipe. In order to cope with the two different scenarios of floors and carpets, different types of roller brushes are set for cleaning. Specifically, soft velvet roller brushes are usually used to clean floors, and bristle or leather roller brushes are used to clean carpets. However, users are generally required to manually replace two different types of roller brushes according to different cleaning surfaces, which is cumbersome.

[0003] The floor brush in the related art is provided with double rollers to adapt to different cleaning surfaces. However, since a roller is added, a transmission mechanism is added, which increases the load of the motor and makes the structure complicated. Moreover, the additional roller is easy to be entangled with hair and other debris when rotating, and needs to be cleaned manually regularly, which is cumbersome. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a cleaning brush.

[0006] A second aspect of the embodiments of the present utility model provides a vacuum cleaner.

[0007] In view of this, according to the first aspect of an embodiment of the utility model, a cleaning floor brush is provided, which includes: a shell body, the shell body is provided with a working chamber; a first roller brush is rotatably arranged in the working chamber; a second roller brush is located on at least one side of the first roller brush along the radial direction of the first roller brush; a roller assembly is rotatably arranged in the shell body and connected to the second roller brush, at least a portion of the roller assembly is exposed in the working chamber for contacting the surface to be cleaned.

[0008] The cleaning floor brush provided by the embodiment of the utility model includes a housing, a first roller brush, a second roller brush and a roller assembly. Specifically, the housing is provided with a working chamber. Optionally, the housing is also provided with a suction port, which is connected to the working chamber. The suction pipeline of the vacuum cleaner is connected to the suction port. When the fan assembly of the vacuum cleaner is in a working state, a suction airflow can be generated. Under the action of the suction airflow, the working chamber, the suction port and the suction pipeline capture the sundries on the surface to be cleaned into the collection chamber of the vacuum cleaner, thereby achieving dust removal on the surface to be cleaned.

[0009] The surfaces to be cleaned include floors, carpets and other surfaces that need to be cleaned.

[0010] The first roller brush is rotatably arranged in the working chamber. Optionally, the cleaning floor brush further comprises a motor, which is connected to the first roller brush, so that the first roller brush can rotate in the working chamber under the drive of the motor, that is, the first roller brush is an electric floor brush.

[0011] The second roller brush is located on at least one side of the first roller brush in the radial direction. Specifically, along the radial direction of the first roller brush, the first roller brush includes a first side and a second side opposite to each other, and the second roller brush is arranged on the first side of the first roller brush, or, the second roller brush is arranged on the second side of the first roller brush, or, the number of the second roller brushes is two, and the two second roller brushes are arranged on the first side and the second side of the first roller brush, respectively. It can be understood that along the movement direction of the cleaning brush on the surface to be cleaned, the first side is the front side, and the second side is the rear side. That is, the second roller brush is located on the front side and / or the rear side of the first roller brush. It can be specifically set according to actual needs.

[0012] Since the first roller brush and the second roller brush are provided, it can adapt to different surfaces to be cleaned, ensuring the dust removal effect without the user having to manually replace different types of roller brushes according to the usage scenarios, thereby improving the user experience of the cleaning floor brush.

[0013] The roller assembly is connected to the second roller brush, and at least a portion of the roller assembly is exposed outside the working cavity, and the portion of the roller assembly exposed outside the working cavity can contact the surface to be cleaned, so that under the action of the friction force generated by the contact between the roller assembly and the surface to be cleaned, the roller assembly rotates on the surface to be cleaned, thereby driving the second roller brush to rotate.

[0014] Since the friction force generated by the contact between the roller assembly and the surface to be cleaned drives the second roller brush to rotate, there is no need to set up a transmission mechanism to drive the second roller brush to rotate, which simplifies the structure of the cleaning floor brush and reduces the load on the motor. This can ensure the cleaning effect in different scenes while reducing the production cost of the cleaning floor brush and improving the reliability of the cleaning floor brush.

[0015] In addition, since the roller assembly rotates by utilizing the friction force generated by the contact between the roller assembly and the surface to be cleaned, the rotation speed of the second roller brush is relatively low, so that hair and other debris on the surface to be cleaned are sucked away by the negative pressure before they have time to be entangled on the second roller brush. That is, hair and other debris are not easily entangled on the second roller brush, which effectively improves the anti-entanglement ability of the second roller brush. There is no need to manually clean the second roller brush regularly, which further improves the user experience of the cleaning floor brush.

[0016] In addition, the cleaning floor brush provided according to the above technical solution of the utility model also has the following additional technical features:

[0017] In some technical solutions, optionally, the roller assembly includes a first roller and a second roller, and the first roller and the second roller are respectively located at two ends of the second roller brush in the axial direction and are respectively connected to the second roller brush.

[0018] In this technical solution, it is defined that the roller assembly includes a first roller and a second roller. Specifically, along the axial direction of the second roller brush, the first roller and the second roller are respectively located at two ends of the second roller brush, and the first roller and the second roller are respectively connected to the second roller brush. That is to say, the first roller and the second roller simultaneously drive the second roller brush to rotate, ensuring that the second roller brush can roll hair and other debris on the surface to be cleaned into the working chamber during rotation, thereby ensuring the dust removal effect of the cleaning floor brush.

[0019] It can be understood that a portion of the first roller and a portion of the second roller are respectively exposed outside the working chamber, that is, a portion of the first roller and a portion of the second roller are in contact with the surface to be cleaned, so that under the action of the friction force generated by the contact between the first roller and the second roller and the surface to be cleaned respectively, the first roller and the second roller respectively rotate on the surface to be cleaned, thereby driving the second roller brush to rotate.

[0020] There is no need to set up a transmission mechanism to drive the second roller brush to rotate, which simplifies the structure of the cleaning floor brush and reduces the load on the motor. This can reduce the production cost of the cleaning floor brush and improve the reliability of the cleaning floor brush while ensuring the cleaning effect in different scenes.

[0021] Moreover, the rotation speed of the second roller brush is relatively low, so that hair and other debris on the surface to be cleaned are sucked away by negative pressure before they have time to entangle on the second roller brush. That is, hair and other debris are not easily entangled on the second roller brush, effectively improving the anti-entanglement ability of the second roller brush.

[0022] In some technical solutions, optionally, the first roller, the second roller and the second roller brush are coaxially arranged.

[0023] In this technical solution, the first roller, the second roller and the second roller brush are coaxially arranged, thereby ensuring that the second roller brush can rotate driven by the first roller and the second roller, and further ensuring that the second roller brush can roll hair and other debris on the surface to be cleaned into the working chamber during rotation, thereby ensuring the dust removal effect of the cleaning brush.

[0024] It can be understood that, since the first roller, the second roller and the second roller brush are coaxially arranged, the rotation speeds of the first roller, the second roller and the second roller brush are consistent.

[0025] In some technical solutions, optionally, a friction structure is provided on the outer peripheral surface of at least one of the first roller and the second roller.

[0026] In the technical solution, it is defined that the outer peripheral surface of at least one of the first roller and the second roller is provided with a friction structure, specifically, the outer peripheral surface of the first roller is provided with a friction structure. Alternatively, the outer peripheral surface of the second roller is provided with a friction structure. Alternatively, the outer peripheral surface of the first roller and the outer peripheral surface of the second roller are respectively provided with a friction structure. The specific configuration can be based on actual needs.

[0027] It can be understood that the friction structure is exposed in the working cavity, that is, the friction structure can contact the surface to be cleaned, thereby significantly improving the friction between the first roller and / or the second roller having the friction structure and the surface to be cleaned, preventing the first roller and / or the second roller from slipping on the surface to be cleaned, and facilitating the first roller and / or the second roller to rotate on the surface to be cleaned, thereby driving the second roller brush to rotate, thereby ensuring the dust removal effect of the cleaning brush in different cleaning scenarios.

[0028] In some technical solutions, optionally, the friction structure includes a protrusion, and at least a portion of the protrusion extends along the circumference of the first roller and / or the second roller.

[0029] In this technical solution, it is defined that the friction structure includes a protrusion. Specifically, when the protrusion is provided on the outer wall of the first roller, the protrusion extends along the circumference of the first roller. When the protrusion is provided on the outer wall of the second roller, the protrusion extends along the circumference of the second roller. When the protrusion is provided on the outer wall of the first roller and the outer wall of the second roller is also provided with a protrusion, the protrusion on the first roller extends along the circumference of the first roller, and the protrusion on the second roller extends along the circumference of the second roller.

[0030] The protrusion can contact the surface to be cleaned, thereby significantly improving the friction between the first roller and / or the second roller having the protrusion and the surface to be cleaned, preventing the first roller and / or the second roller from slipping on the surface to be cleaned, and facilitating the first roller and / or the second roller to rotate on the surface to be cleaned.

[0031] In some technical solutions, optionally, at least one of the first roller and the second roller includes a hub and a protective member, wherein the hub is connected to the second roller brush, the protective member is arranged on the outside of the hub, and the outer wall of the protective member is provided with a friction structure.

Alternatively, the second roller includes a hub and a protective member. Alternatively, the first roller and the second roller include a hub and a protective member respectively. The specific configuration can be made according to actual needs.

[0033] The wheel hub is connected to the second roller brush, and the protective member is arranged on the outside of the wheel hub, that is, the wheel hub is wrapped by the protective member to protect the wheel hub, which can effectively reduce the wear of the wheel hub and thus extend the service life of the first roller and / or the second roller with the protective member.

[0034] The outer wall of the protective part is provided with a friction structure. Since the friction structure is exposed in the working cavity, that is, the friction structure can contact the surface to be cleaned, the friction force between the first roller and / or the second roller with the friction structure and the surface to be cleaned can be significantly improved, preventing the first roller and / or the second roller from slipping on the surface to be cleaned, which is conducive to the first roller and / or the second roller to rotate on the surface to be cleaned, thereby driving the second roller brush to rotate, ensuring the dust removal effect of the cleaning brush in different cleaning scenarios.

[0035] In some technical solutions, optionally, the protective part includes a wear-resistant part.

[0036] In this technical solution, it is defined that the protective member includes a wear-resistant member, so that the service life of the protective member can be extended while protecting the wheel hub.

[0037] Optionally, the protective member includes rubber, silicone or the like.

[0038] In some technical solutions, optionally, the second roller brush includes a brush body and a connecting shaft, wherein the brush body is provided with an axis hole, and the connecting shaft passes through the axis hole to be connected to the roller assembly.

[0039] In this technical solution, it is defined that the second roller brush includes a brush body and a connecting shaft. Specifically, the brush body is provided with an axial hole, the connecting shaft is passed through the axial hole, and the connecting shaft is connected to the roller assembly, that is, the roller assembly drives the brush body to rotate through the connecting shaft.

[0040] It can be understood that there is no relative rotation between the connecting shaft and the brush body, so that the connecting shaft can drive the brush body to rotate.

[0041] In some technical solutions, optionally, the first roller brush is provided with a plurality of first brushes; the second roller brush also includes a plurality of second brushes, and the plurality of second brushes are provided on the outer wall of the brush body; wherein the hardness of at least one second brush is less than the hardness of each first brush.

[0042] In this technical solution, it is defined that the second roller brush further includes a plurality of second brushes, specifically, the plurality of second brushes are arranged on the outer wall of the brush body. The first roller brush is provided with a plurality of first brushes.

[0043] Specifically, the hardness of at least one second brush is less than the hardness of each first brush, that is, the second brush on the second roller brush is set to be relatively soft. The first brush on the first roller brush is set to be relatively hard. Thus, the first roller brush and the second roller brush can be adapted to the use scenarios of different types of surfaces to be cleaned, ensuring the cleaning effect. And the user does not need to manually change different types of roller brushes according to the use scenario, thereby improving the user's experience of using the cleaning brush.

[0044] Optionally, the hardness of each second brush is smaller than the hardness of each first brush.

[0045] In some technical solutions, optionally, the cleaning floor brush also includes a connecting tube, which is arranged in the shell and connected to the working chamber; wherein the shell is also provided with an opening, which is located on the side of the shell away from the connecting tube and connected to the working chamber, and the second roller brush is arranged at the opening.

[0046] In this technical solution, it is defined that the cleaning brush also includes a connecting pipe.

[0047] The shell is also provided with an opening. Specifically, the opening is located on the side of the shell away from the connecting pipe, that is, the opening is located on the front side of the shell, that is, the opening is a front end opening, and the opening is connected to the working chamber.

[0048] The second roller brush is arranged at the opening. On the one hand, when the second roller brush rotates relative to the housing, the hair and other fabrics on the surface to be cleaned and larger particles of debris can be rolled into the working chamber and sucked into the collection chamber of the vacuum cleaner through the suction port and the connecting pipe, thereby improving the cleaning effect. On the other hand, the second roller brush is arranged at the opening to improve the sealing of the working chamber when the cleaning brush is in the working state, enhance the suction force of the vacuum cleaner, and thus improve the dust removal efficiency of the vacuum cleaner.

[0049] Compared with the related art of manually adjusting the opening size according to the size of the debris particles, the operation process of the cleaning floor brush can be significantly simplified, further improving the user experience.

DETAILED DESCRIPTION

[0061] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0063] Refer to the following Figures 1 to 3 The cleaning brush 100 and the vacuum cleaner provided according to some embodiments of the present invention are described.

[0064] In one embodiment according to the present application, Figure 1 , Figure 2 and Figure 3 As shown, a cleaning floor brush 100 is proposed, and the cleaning floor brush 100 includes: a shell 110, and the shell 110 is provided with a working chamber 111; a first roller brush 120, which is rotatably disposed in the working chamber 111; a second roller brush 130, along the radial direction of the first roller brush 120, the second roller brush 130 is located on at least one side of the first roller brush 120; a roller assembly 140, which is rotatably disposed in the shell 110 and connected to the second roller brush 130, and at least a portion of the roller assembly 140 is exposed in the working chamber 111 for contacting the surface to be cleaned.

[0065] The cleaning floor brush 100 provided in the embodiment of the utility model comprises a housing 110, a first roller brush 120, a second roller brush 130 and a roller assembly 140. Specifically, the housing 110 is provided with a working chamber 111. Optionally, the housing 110 is also provided with a suction port, which is connected to the working chamber 111. The suction pipeline of the vacuum cleaner is connected to the suction port. When the fan assembly of the vacuum cleaner is in a working state, a suction airflow can be generated. Under the action of the suction airflow, the working chamber 111, the suction port and the suction pipeline capture the sundries on the surface to be cleaned into the collection chamber of the vacuum cleaner, thereby achieving dust removal on the surface to be cleaned.

[0066] The surfaces to be cleaned include floors, carpets and other surfaces that need to be cleaned.

[0067] The first roller brush 120 is rotatably disposed in the working chamber 111. Optionally, the cleaning floor brush 100 further includes a motor connected to the first roller brush 120, so that the first roller brush 120 can rotate in the working chamber 111 under the drive of the motor, that is, the first roller brush 120 is an electric floor brush.

[0068] The second roller brush 130 is located on at least one side of the first roller brush 120 in the radial direction. Specifically, along the radial direction of the first roller brush 120, the first roller brush 120 includes a first side and a second side opposite to each other, and the second roller brush 130 is arranged on the first side of the first roller brush 120, or, the second roller brush 130 is arranged on the second side of the first roller brush 120, or, the number of the second roller brushes 130 is two, and the two second roller brushes 130 are respectively arranged on the first side and the second side of the first roller brush 120. It can be understood that along the movement direction of the cleaning floor brush 100 on the surface to be cleaned, the first side is the front side and the second side is the rear side. That is, the second roller brush 130 is located on the front side and / or the rear side of the first roller brush 120. It can be specifically set according to actual needs.

[0069] Since the first roller brush 120 and the second roller brush 130 are provided, they can adapt to different surfaces to be cleaned, ensuring the dust removal effect without the user having to manually replace different types of roller brushes according to the usage scenario, thereby improving the user experience of the cleaning floor brush 100.

[0070] The roller assembly 140 is connected to the second roller brush 130, and at least a portion of the roller assembly 140 is exposed outside the working chamber 111, and the portion of the roller assembly 140 exposed outside the working chamber 111 can contact the surface to be cleaned, so that under the action of the friction force generated by the contact between the roller assembly 140 and the surface to be cleaned, the roller assembly 140 rotates on the surface to be cleaned, thereby driving the second roller brush 130 to rotate.

[0071] Since the friction force generated by the contact between the roller assembly 140 and the surface to be cleaned drives the second roller brush 130 to rotate, there is no need to set up a transmission mechanism to drive the second roller brush 130 to rotate, which simplifies the structure of the cleaning floor brush 100 and reduces the load of the motor. This can ensure the cleaning effect in different scenes while reducing the production cost of the cleaning floor brush 100 and improving the reliability of the cleaning floor brush 100.

[0072] In addition, since the roller assembly 140 rotates by utilizing the friction force generated by the contact between the roller assembly 140 and the surface to be cleaned, the rotation speed of the second roller brush 130 is relatively low, so that hair and other debris on the surface to be cleaned are sucked away by the negative pressure before they have time to be entangled on the second roller brush 130, that is, hair and other debris are not easily entangled on the second roller brush 130, which effectively improves the anti-entanglement ability of the second roller brush 130, and there is no need to manually clean the second roller brush 130 regularly, further improving the user experience of the cleaning floor brush 100.

[0073] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the roller assembly 140 includes a first roller 141 and a second roller 142 , and the first roller 141 and the second roller 142 are respectively located at two ends of the second roller brush 130 in the axial direction and are respectively connected to the second roller brush 130 .

[0074] In this embodiment, it is defined that the roller assembly 140 includes a first roller 141 and a second roller 142. Specifically, along the axial direction of the second roller brush 130, the first roller 141 and the second roller 142 are respectively located at two ends of the second roller brush 130, and the first roller 141 and the second roller 142 are respectively connected to the second roller brush 130. That is to say, the first roller 141 and the second roller 142 simultaneously drive the second roller brush 130 to rotate, ensuring that the second roller brush 130 can roll hair and other debris on the surface to be cleaned into the working chamber 111 during the rotation process, thereby ensuring the dust removal effect of the cleaning floor brush 100.

[0075] It can be understood that a portion of the first roller 141 and a portion of the second roller 142 are respectively exposed outside the working chamber 111, that is, a portion of the first roller 141 and a portion of the second roller 142 are in contact with the surface to be cleaned, so that under the action of the friction force generated by the contact between the first roller 141 and the second roller 142 and the surface to be cleaned, the first roller 141 and the second roller 142 respectively rotate on the surface to be cleaned, thereby driving the second roller brush 130 to rotate.

[0076] There is no need to set up a transmission mechanism to drive the second roller brush 130 to rotate, which simplifies the structure of the cleaning floor brush 100 and reduces the load of the motor, thereby ensuring the cleaning effect in different scenes while reducing the production cost of the cleaning floor brush 100 and improving the reliability of the cleaning floor brush 100.

[0077] Moreover, the rotation speed of the second roller brush 130 is relatively low, so that hair and other debris on the surface to be cleaned are sucked away by the negative pressure before they have a chance to entangle on the second roller brush 130, that is, hair and other debris are not easily entangled on the second roller brush 130, effectively improving the anti-entanglement ability of the second roller brush 130.

[0078] In some embodiments, optionally, the first roller 141 , the second roller 142 and the second roller brush 130 are coaxially arranged.

[0079] In this embodiment, the first roller 141, the second roller 142 and the second roller brush 130 are coaxially arranged, thereby ensuring that the second roller brush 130 can rotate under the drive of the first roller 141 and the second roller 142, and further ensuring that the second roller brush 130 can roll hair and other debris on the surface to be cleaned into the working chamber 111 during the rotation process, thereby ensuring the dust removal effect of the cleaning brush 100.

[0080] It can be understood that, since the first roller 141 , the second roller 142 and the second roller brush 130 are coaxially arranged, the rotation speeds of the first roller 141 , the second roller 142 and the second roller brush 130 are consistent.

[0081] like Figure 3As shown, in some embodiments, optionally, a friction structure 150 is provided on the outer peripheral surface of at least one of the first roller 141 and the second roller 142 .

[0082] In this embodiment, it is defined that the outer circumference of at least one of the first roller 141 and the second roller 142 is provided with a friction structure 150. Specifically, the outer circumference of the first roller 141 is provided with a friction structure 150. Alternatively, the outer circumference of the second roller 142 is provided with a friction structure 150. Alternatively, the outer circumference of the first roller 141 and the outer circumference of the second roller 142 are respectively provided with a friction structure 150. The specific configuration can be based on actual needs.

[0083] It can be understood that the friction structure 150 is exposed to the working chamber 111, that is, the friction structure 150 can contact the surface to be cleaned, thereby significantly improving the friction between the first roller 141 and / or the second roller 142 having the friction structure 150 and the surface to be cleaned, preventing the first roller 141 and / or the second roller 142 from slipping on the surface to be cleaned, and facilitating the first roller 141 and / or the second roller 142 to rotate on the surface to be cleaned, thereby driving the second roller brush 130 to rotate, thereby ensuring the dust removal effect of the cleaning brush 100 in different cleaning scenarios.

[0084] In some embodiments, optionally, the friction structure 150 includes a protrusion, and at least a portion of the protrusion extends along the circumference of the first roller 141 and / or the second roller 142 .

[0085] In this embodiment, it is defined that the friction structure 150 includes a protrusion. Specifically, when a protrusion is provided on the outer wall of the first roller 141, the protrusion extends along the circumference of the first roller 141. When a protrusion is provided on the outer wall of the second roller 142, the protrusion extends along the circumference of the second roller 142. When a protrusion is provided on the outer wall of the first roller 141 and a protrusion is also provided on the outer wall of the second roller 142, the protrusion on the first roller 141 extends along the circumference of the first roller 141, and the protrusion on the second roller 142 extends along the circumference of the second roller 142.

[0086] The protrusion can contact the surface to be cleaned, thereby significantly improving the friction between the first roller 141 and / or the second roller 142 having the protrusion and the surface to be cleaned, preventing the first roller 141 and / or the second roller 142 from slipping on the surface to be cleaned, and facilitating the first roller 141 and / or the second roller 142 to rotate on the surface to be cleaned.

[0087] like Figure 3As shown, in some embodiments, optionally, at least one of the first roller 141 and the second roller 142 includes a hub 160 and a protective member 170, wherein the hub 160 is connected to the second roller brush 130, the protective member 170 is disposed on the outer side of the hub 160, and the outer wall of the protective member 170 is provided with a friction structure 150.

[0088] In this embodiment, it is defined that at least one of the first roller 141 and the second roller 142 includes a hub 160 and a protective member 170. Specifically, the first roller 141 includes the hub 160 and the protective member 170. Alternatively, the second roller 142 includes the hub 160 and the protective member 170. Alternatively, the first roller 141 and the second roller 142 include the hub 160 and the protective member 170, respectively. The specific configuration can be made according to actual needs.

[0089] The wheel hub 160 is connected to the second roller brush 130, and the protective member 170 is arranged on the outside of the wheel hub 160. That is, the wheel hub 160 is wrapped by the protective member 170 to protect the wheel hub 160, which can effectively reduce the wear of the wheel hub 160 and further extend the service life of the first roller 141 and / or the second roller 142 with the protective member 170.

[0090] The outer wall of the protective member 170 is provided with a friction structure 150. Since the friction structure 150 is exposed to the working chamber 111, that is, the friction structure 150 can contact the surface to be cleaned, the friction force between the first roller 141 and / or the second roller 142 having the friction structure 150 and the surface to be cleaned can be significantly improved, preventing the first roller 141 and / or the second roller 142 from slipping on the surface to be cleaned, which is beneficial for the first roller 141 and / or the second roller 142 to rotate on the surface to be cleaned, thereby driving the second roller brush 130 to rotate, thereby ensuring the dust removal effect of the cleaning brush 100 in different cleaning scenarios.

[0091] In some embodiments, the protective member 170 optionally comprises a wear-resistant member.

[0092] In this embodiment, the protection member 170 is defined to include a wear-resistant member, so that the service life of the protection member 170 can be extended while protecting the wheel hub 160 .

[0093] Optionally, the protective member 170 includes rubber, silicone or the like.

[0094] like Figure 3 As shown, in some embodiments, optionally, the second roller brush 130 includes a brush body 131 and a connecting shaft 132 , wherein the brush body 131 is provided with an axis hole 134 , and the connecting shaft 132 passes through the axis hole 134 to be connected to the roller assembly 140 .

[0095] In this embodiment, it is defined that the second roller brush 130 includes a brush body 131 and a connecting shaft 132. Specifically, the brush body 131 is provided with an axial hole 134, the connecting shaft 132 is passed through the axial hole 134, and the connecting shaft 132 is connected to the roller assembly 140. That is, the roller assembly 140 drives the brush body 131 to rotate through the connecting shaft 132.

[0096] It is understandable that there is no relative rotation between the connecting shaft 132 and the brush body 131 , so that the connecting shaft 132 can drive the brush body 131 to rotate.

[0097] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, the first roller brush 120 is provided with a plurality of first brushes 121; the second roller brush 130 also includes a plurality of second brushes 133, and the plurality of second brushes 133 are provided on the outer wall of the brush body 131; wherein, the hardness of at least one second brush 133 is less than the hardness of each first brush 121.

[0098] In this embodiment, it is defined that the second rolling brush 130 further includes a plurality of second brushes 133 . Specifically, the plurality of second brushes 133 are disposed on the outer wall of the brush body 131 . The first rolling brush 120 is provided with a plurality of first brushes 121 .

[0099] Specifically, the hardness of at least one second brush 133 is smaller than the hardness of each first brush 121, that is, the second brush 133 on the second roller brush 130 is set to be relatively soft. The first brush 121 on the first roller brush 120 is set to be relatively hard.

[0100] Therefore, the first roller brush 120 and the second roller brush 130 can be adapted to different types of surfaces to be cleaned, thereby ensuring a cleaning effect. The user does not need to manually replace different types of roller brushes according to the usage scenario, thereby improving the user's experience of using the cleaning floor brush 100.

[0101] Optionally, the hardness of each second brush 133 is smaller than the hardness of each first brush 121 .

[0102] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cleaning floor brush 100 also includes a connecting pipe 180, which is disposed in the shell 110 and is connected to the working chamber 111; wherein the shell 110 is also provided with an opening 112, which is located on the side of the shell 110 away from the connecting pipe 180 and is connected to the working chamber 111, and the second roller brush 130 is disposed at the opening 112.

[0103] In this embodiment, it is defined that the cleaning brush 100 further includes a connecting pipe 180. Specifically, the connecting pipe 180 is disposed on the housing 110, and the connecting pipe 180 is connected to the working chamber 111. It can be understood that the connecting pipe 180 is located at the rear side of the housing 110 along the movement direction of the cleaning brush 100 on the surface to be cleaned, that is, the cleaning brush 100 is pushed forward or pulled backward on the surface to be cleaned.

[0104] The shell 110 is also provided with an opening 112 . Specifically, the opening 112 is located on the side of the shell 110 away from the connecting pipe 180 , that is, the opening 112 is located on the front side of the shell 110 , that is, the opening 112 is a front opening, and the opening 112 is connected to the working chamber 111 .

[0105] The second roller brush 130 is arranged at the opening 112. On the one hand, during the rotation of the second roller brush 130 relative to the shell 110, hair and other fabrics and larger particles of debris on the surface to be cleaned can be rolled into the working chamber 111 and sucked into the collection chamber of the vacuum cleaner through the suction port and the connecting pipe 180, thereby improving the cleaning effect.

[0106] On the other hand, disposing the second roller brush 130 at the opening 112 can improve the sealing of the working chamber 111 when the cleaning brush 100 is in working state, enhance the suction force of the vacuum cleaner, and further improve the dust removal efficiency of the vacuum cleaner.

[0107] Compared with the related art of manually adjusting the opening size according to the size of the debris particles, the operation process of the cleaning floor brush 100 can be significantly simplified, further improving the user experience.

[0108] In some embodiments, optionally, the first roller brush 120 is a bristle roller brush; and / or the second roller brush 130 is a soft velvet roller brush.

[0109] In this embodiment, the first roller brush 120 is a bristle roller brush, and the second roller brush 130 is a soft velvet roller brush, so that the first roller brush 120 and the second roller brush 130 can adapt to different types of surfaces to be cleaned, ensuring the cleaning effect. And the user does not need to manually change different types of roller brushes according to the usage scenario, thereby improving the user's experience of the cleaning floor brush 100.

[0110] In addition, the second roller brush 130 is a soft-pile roller brush, which contacts the surface to be cleaned, thereby improving the sealing of the working chamber 111, enhancing the suction force of the vacuum cleaner, and thereby improving the dust removal efficiency of the vacuum cleaner.
