Description

Technical Field

[0001] The utility model relates to the technical field of floor brushes, in particular to a floor brush assembly 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 the related art, the roller brush in the electric floor brush is easy to be entangled with hair and other debris during operation, and the user needs to manually clean the hair on the roller brush, which brings great inconvenience to the user. Utility Model Content

[0003] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the utility model provides a floor brush assembly.

[0005] A second aspect of the embodiments of the present utility model provides a vacuum cleaner.

[0006] In view of this, according to the first aspect of an embodiment of the utility model, a floor brush assembly is provided, which includes: a shell body, the shell body is provided with a working chamber; a roller brush, rotatably arranged in the working chamber, the roller brush is provided with a plurality of implanted bristles; a comb tooth structure, arranged on the inner wall of the shell body located in the working chamber, along the radial direction of the roller brush, at least a part of the comb tooth structure is located on the outer peripheral side of the roller brush, the comb tooth structure includes a plurality of comb teeth, and at least one comb tooth can be inserted between any two adjacent implanted bristles.

[0007] The floor brush assembly provided by the embodiment of the utility model includes a shell, a roller brush and a comb tooth structure. Specifically, the shell is provided with a working chamber. Optionally, the shell is also provided with an air suction port, which is connected to the working chamber, and the air suction port is connected to the exhaust duct of the vacuum cleaner, and the exhaust duct is connected to the fan assembly of the vacuum cleaner. When the fan assembly is in a working state, a suction airflow is generated, thereby sucking debris particles or hair and other fabrics on the surface to be cleaned into the exhaust duct, thereby realizing the cleaning process of the vacuum cleaner.

[0008] The surfaces to be cleaned include floors, carpets and other surfaces that need to be cleaned.

[0009] The roller brush is rotatably arranged in the working chamber. Optionally, the floor brush assembly further comprises a motor, which is connected to the roller brush, so that the roller brush can rotate in the working chamber under the drive of the motor, that is, the roller brush is an electric floor brush.

[0010] It is understandable that during the process of the floor brush assembly cleaning the surface to be cleaned, hair and other debris are easily entangled in the roller brush, requiring regular manual cleaning, which is inconvenient to operate and reduces the user experience.

[0011] The comb tooth structure is arranged on the inner wall of the housing located in the working chamber, and along the radial direction of the roller brush, at least a part of the comb tooth structure is located on the outer periphery of the roller brush. Specifically, the comb tooth structure includes a plurality of comb teeth, and at least one comb tooth can be inserted between any two adjacent implanted hairs.

[0012] Optionally, one comb tooth is inserted between two adjacent implanted hairs. Alternatively, multiple comb teeth are inserted between two adjacent implanted hairs simultaneously or successively. The specific configuration can be made according to actual needs.

[0013] It is understandable that, when the roller brush rotates relative to the shell in the working chamber, hair and other fabrics are easily entangled on the roller brush, especially between adjacent hair plantings. By inserting at least one comb tooth between any two adjacent hair plantings, the hair and other fabrics entangled on the roller brush can be combed, so that the entangled hair and other fabrics pass over the hair plantings and are sucked into the air intake of the vacuum cleaner, so as to reduce the amount of hair and other fabrics entangled on the roller brush after long-term use of the roller brush, without the need for manual cleaning by the user, thereby improving the convenience of user use and thus improving the user experience.

[0014] Moreover, compared with the related art in which the hair entanglement effect is reduced by adding structures such as leather strips or blades, the structure is simple and can significantly reduce the production cost of the floor brush assembly.

[0015] In addition, since at least one comb tooth is inserted between two adjacent implanted hairs, compared with the related art of using a comb tooth structure to reduce the hair entanglement effect, the distance between the comb teeth and the hair and other fabrics entangled on the roller brush can be significantly reduced, thereby enabling the floor brush assembly to have a good anti-entanglement effect without increasing product costs.

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

[0017] In some technical schemes, optionally, the roller brush includes a brush body, which is rotatably connected to the shell, and a plurality of transplanted bristles are arranged at intervals on the brush body, and at least a portion of each transplanted bristle protrudes from the outer wall of the brush body; wherein, when at least one comb tooth is inserted between any two adjacent transplanted bristles, along the radial direction of the roller brush, the width of the gap between one end of the comb tooth facing the brush body and the outer wall of the brush body is less than or equal to a preset value.

[0018] In this technical solution, it is defined that the roller brush includes a brush body. Specifically, the brush body is rotatably connected to the shell, and a plurality of implanted hairs are arranged at intervals on the brush body. When the floor brush assembly is in a working state, the brush body drives the plurality of implanted hairs to rotate relative to the shell to clean the surface to be cleaned. By arranging a plurality of implanted hairs at intervals on the brush body, it is convenient for the roller brush to pick up debris on the surface to be cleaned, thereby improving the cleaning effect of the vacuum cleaner having the floor brush assembly.

[0019] When at least one comb tooth is inserted between any two adjacent transplanted hairs, along the radial direction of the roller brush, the width of the gap between the end of the comb tooth facing the brush body and the outer wall of the brush body is less than or equal to a preset value. That is, when at least one comb tooth is inserted between two adjacent transplanted hairs, the gap between the inserted end of the comb tooth and the outer wall of the brush body is smaller, thereby further shortening the distance between the comb tooth and the hair or other fabrics wrapped around the outer wall of the brush body. Further, under the combing of the comb tooth structure, the hair or other fabrics wrapped around the outer wall of the brush body can be sucked away after passing through the transplanted hairs, thereby improving the anti-entanglement effect of the floor brush assembly.

[0020] Optionally, the brush body is a cylinder, or the cylinder is concave in the middle of the axial direction. The specific configuration can be made according to actual needs.

[0021] In some technical solutions, optionally, along the radial direction of the roller brush, the width h of the gap satisfies 0mm<h≤1mm.

[0022] In this technical solution, the width of the gap in the radial direction of the roller brush is defined. Specifically, the width of the gap is less than or equal to 1 mm and greater than 0 mm. That is to say, when at least one comb tooth is inserted between two adjacent implanted hairs, there is a gap between the insertion end of the comb tooth and the outer wall of the brush body, and the width of the gap is small. This can further improve the anti-entanglement ability of the roller brush while reducing the manufacturing difficulty of the comb tooth structure, thereby reducing the production cost of the floor brush assembly.

[0023] It is understandable that if the width of the gap along the radial direction of the roller brush is large, that is, h is greater than 1 mm, the comb teeth inserted between two adjacent transplanted hairs cannot touch the hair and other fabrics wrapped around the brush body, making it impossible for hair and other fabrics to pass over the transplanted hair. After long-term use, the debris on the roller brush needs to be cleaned, affecting the user experience.

[0024] In some technical solutions, optionally, along the radial direction of the roller brush, the width of the gap is equal to 0 mm.

[0025] In this technical solution, the width of the gap in the radial direction of the roller brush is limited to 0 mm, that is, when at least one comb tooth is inserted between two adjacent transplanted hairs, the inserted end of the comb tooth just contacts the outer wall of the brush body, so that the comb tooth inserted between two adjacent transplanted hairs can fully contact the hair and other fabrics wrapped around the outer wall of the brush body, so that the hair and other fabrics can quickly pass over the transplanted hair and be sucked in, significantly improving the anti-entanglement effect.

[0026] Optionally, along the radial direction of the roller brush, the distance between the inner wall of the shell where the comb teeth are located and the outer wall of the brush body is smaller than the length of the comb teeth, that is, the comb teeth inserted between two adjacent implanted hairs are in contact with the outer wall of the brush body, and the insertion end of the comb teeth is partially bent, that is, the comb teeth and the outer wall of the brush body are interference fit, thereby improving the anti-entanglement effect of the floor brush assembly. It is understandable that during the rotation of the roller brush relative to the shell, the outer wall of the brush body will grind off the interference part of the comb teeth.

[0027] In some technical solutions, optionally, the outer wall of the brush body is provided with a groove, and at least one implanted hair is located in the groove.

[0028] In this technical solution, it is stipulated that the outer wall of the brush body is provided with a groove. Specifically, at least one transplanted hair is located in the groove. Under the premise that the transplanted hair protrudes from the outer wall of the brush body for a certain length, the length of at least one transplanted hair is increased, that is, the distance between the root of the transplanted hair and the outer wall of the brush body is increased, thereby lengthening the cantilever of the transplanted hair, thereby reducing the resistance of the transplanted hair to the movement of hair and other fabrics entangled on the outer wall of the brush body toward the air suction port, so that hair and other fabrics can be quickly sucked over the transplanted hair under the combing of the comb tooth structure, further improving the anti-entanglement effect of the floor brush assembly, and no regular manual cleaning is required, thereby enhancing the user experience.

[0029] Moreover, by arranging at least one implanted hair in the groove, it is also possible to effectively prevent the problem of hair and other fabrics being entangled in the roots of the implanted hair, thereby making it difficult to move the hair and other fabrics, thereby improving the anti-entanglement effect of the floor brush assembly.

[0030] Optionally, a plurality of implanted bristles are located in the groove to further improve the anti-entanglement effect of the floor brush assembly.

[0031] In some technical solutions, optionally, the rotation speed P of the roller brush satisfies 2000rpm≤P≤5000rpm.

[0032] In this technical solution, the rotation speed of the roller brush is limited to between 2000rpm and 5000rpm. That is, the rotation speed of the roller brush relative to the housing is increased, so that hair and other fabrics can be thrown out from the surface of the brush body under the action of centrifugal force. Even if there is a gap between the insertion end of the comb teeth and the outer wall of the brush body, the centrifugal force can be used to make the comb teeth touch the hair and other fabrics entangled on the brush body, further improving the anti-entanglement ability of the roller brush, eliminating the need for manual cleaning, and improving the convenience of user use.

[0033] It is understandable that if the rotation speed of the roller brush is too high, that is, P is greater than 5000 rpm, the load requirement for the motor driving the roller brush to rotate will be higher, and the noise of the floor brush assembly during operation will also be greater.

[0034] In some technical solutions, optionally, along the axial direction of the roller brush, the distance between any two adjacent implanted hairs is greater than the width of at least one comb tooth.

[0035] In this technical solution, the axial spacing between any two adjacent planted hairs is limited to be greater than the axial width of at least one comb tooth, so that when the roller brush rotates relative to the shell, at least one comb tooth can be inserted between any two adjacent planted hairs to comb the hair and other fabrics wrapped around the outer wall of the brush body, further improving the anti-entanglement ability of the roller brush, reducing the amount of entanglement of hair and other fabrics on the roller brush after long-term use, without the need for manual cleaning by the user, thereby improving user convenience and further improving the user experience.

[0036] Moreover, compared with the related art in which the hair entanglement effect is reduced by adding structures such as leather strips or blades, the structure is simple and can significantly reduce the production cost of the floor brush assembly.

[0037] In some technical solutions, optionally, a plurality of implanted hairs arranged at intervals along the axial direction of the roller brush form a implanted hair assembly, and the implanted hair assembly extends in a circumferential spiral along the roller brush; and / or a plurality of comb teeth are arranged at intervals along the axial direction of the roller brush.

[0038] In this technical solution, a plurality of implanted hairs arranged at intervals along the axial direction of the roller brush form a implanted hair assembly, that is, a plurality of implanted hairs in the implanted hair assembly are arranged at intervals along the axial direction of the roller brush. The implanted hair assembly extends in a spiral along the circumference of the roller brush, that is, the outer wall of the brush body has spiral implanted hairs.

[0039] Specifically, when using a vacuum cleaner with a floor brush assembly to clean hair, the hair will be partially entangled on the brush body. At this time, under the negative pressure of the vacuum cleaner, the hair will tend to gather towards the middle air inlet, and the hair will make a spiral movement towards the middle under the negative pressure, but the hair on the roller brush will prevent the hair from moving towards the middle air inlet. The rotating roller brush is combed by the multiple teeth of the comb structure, and the hair passes over the hair so that the spiral movement proceeds smoothly. Finally, the hair gathers at the middle air inlet and is sucked into the vacuum cleaner and enters the collection chamber of the vacuum cleaner.

[0040] Multiple comb teeth are arranged at intervals along the axial direction of the roller brush. Since multiple implanted hairs are arranged at intervals along the axial direction of the roller brush, more comb teeth can be inserted between two adjacent implanted hairs during the rotation of the roller brush relative to the shell, so that hair and other fabrics entangled on the outer wall of the brush body can be fully cleaned, further improving the anti-entanglement ability of the floor brush assembly.

[0041] In some technical solutions, optionally, the shell is further provided with an air suction port, which is connected to the working chamber, and at least a part of the air suction port is opposite to the middle part of the roller brush in the axial direction.

[0042] In this technical solution, it is defined that the housing is also provided with an air suction port. Specifically, the air suction port is connected to the working chamber, and at least a part of the air suction port is opposite to the middle part of the roller brush in the axial direction. Specifically, the roller brush includes a first end and a second end that are opposite to each other in the axial direction, the middle part of the roller brush is located between the first end and the second end, and the axial distance between the middle part and the first end is equal to the axial distance between the middle part and the second end. The air suction port is opposite to the middle part of the roller brush, so that it is convenient to suck away particles and other debris entering the working chamber and fabrics such as hair wrapped around the outer wall of the brush body through the air suction port.

[0043] In some technical solutions, optionally, the shell is further provided with an opening, the opening is communicated with the working cavity, and at least a portion of at least one implanted hair is exposed to the working cavity through the opening.

[0044] In this technical solution, it is defined that the shell is also provided with an opening. Specifically, the opening is connected to the working chamber, and at least a portion of at least one implanted hair is exposed to the working chamber through the opening, thereby improving the cleaning effect of the surface to be cleaned and improving the dust removal efficiency.

[0045] According to a second aspect of the utility model, a vacuum cleaner is provided, comprising a floor brush assembly as provided by any of the above technical solutions, and thus having all the beneficial technical effects of the floor brush assembly, which will not be described in detail herein.

[0055] 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.

[0056] 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.

[0057] Refer to the following Figures 1 to 5 The floor brush assembly 100 and the vacuum cleaner provided according to some embodiments of the present utility model are described.

[0058] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a floor brush assembly 100 is proposed, and the floor brush assembly 100 includes: a shell 110, the shell 110 is provided with a working chamber 111; a roller brush 120, rotatably disposed in the working chamber 111, and the roller brush 120 is provided with a plurality of implanted hairs 121; a comb tooth structure 130, disposed on the inner wall of the shell 110 located in the working chamber 111, along the radial direction of the roller brush 120, at least a part of the comb tooth structure 130 is located on the outer peripheral side of the roller brush 120, and the comb tooth structure 130 includes a plurality of comb teeth 131, and at least one comb tooth 131 can be inserted between any two adjacent implanted hairs 121.

[0059] The floor brush assembly 100 provided in the embodiment of the utility model includes a shell 110, a roller brush 120 and a comb tooth structure 130. Specifically, the shell 110 is provided with a working chamber 111. Optionally, the shell 110 is also provided with an air suction port 112, which is connected to the working chamber 111. The air suction port 112 is connected to the exhaust duct of the vacuum cleaner, and the exhaust duct is connected to the fan assembly of the vacuum cleaner. When the fan assembly is in a working state, a suction airflow is generated, thereby sucking debris particles or fabrics such as hair on the surface to be cleaned into the exhaust duct, thereby realizing the cleaning process of the vacuum cleaner.

[0060] The surfaces to be cleaned include floors, carpets and other surfaces that need to be cleaned.

[0061] The roller brush 120 is rotatably disposed in the working chamber 111. Optionally, the floor brush assembly 100 further includes a motor, which is connected to the roller brush 120, so that the roller brush 120 can rotate in the working chamber 111 under the drive of the motor, that is, the roller brush 120 is an electric floor brush.

[0062] It is understandable that during the process of the floor brush assembly 100 cleaning the surface to be cleaned, hair and other debris are easily entangled in the roller brush 120, requiring regular manual cleaning, which is inconvenient to operate and reduces the user experience.

[0063] The comb tooth structure 130 is disposed on the inner wall of the housing 110 located in the working chamber 111, and along the radial direction of the roller brush 120, at least a portion of the comb tooth structure 130 is located at the periphery of the roller brush 120. Specifically, the comb tooth structure 130 includes a plurality of comb teeth 131, and at least one comb tooth 131 can be inserted between any two adjacent implanted hairs 121.

[0064] Optionally, one comb tooth 131 is inserted between two adjacent implanted hairs 121. Alternatively, a plurality of comb teeth 131 are inserted between two adjacent implanted hairs 121 simultaneously or successively. The specific configuration can be made according to actual needs.

[0065] It is understandable that, during the rotation of the roller brush 120 relative to the housing 110 in the working chamber 111, hair and other fabrics are easily entangled on the roller brush 120, especially between adjacent hair plantings 121. By inserting at least one comb tooth 131 between any two adjacent hair plantings 121, the hair and other fabrics entangled on the roller brush 120 can be combed, so that the entangled hair and other fabrics pass over the hair plantings 121 and are sucked into the suction port 112 of the vacuum cleaner, so as to reduce the amount of entanglement of hair and other fabrics on the roller brush 120 after long-term use of the roller brush 120, without the need for manual cleaning by the user, thereby improving the convenience of user use and thus improving the user experience.

[0066] Moreover, compared with the related art in which the hair entanglement effect is reduced by adding structures such as leather strips or blades, the structure is simple and the production cost of the floor brush assembly 100 can be significantly reduced.

[0067] In addition, since at least one comb tooth 131 is inserted between two adjacent implanted hairs 121, compared with the related art of using a comb tooth structure to reduce the hair entanglement effect, the distance between the comb teeth 131 and the hair and other fabrics wrapped around the roller brush 120 can be significantly reduced, thereby enabling the floor brush assembly 100 to have a good anti-entanglement effect without increasing product costs.

[0068] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, the roller brush 120 includes a brush body 122, which is rotatably connected to the shell 110, and a plurality of implanted bristles 121 are arranged at intervals on the brush body 122, and at least a portion of each implanted bristle 121 protrudes from the outer wall of the brush body 122; wherein, when at least one comb tooth 131 is inserted between any two adjacent implanted bristles 121, along the radial direction of the roller brush 120, the width of the gap 150 between one end of the comb tooth 131 facing the brush body 122 and the outer wall of the brush body 122 is less than or equal to a preset value.

[0069] In this embodiment, the roller brush 120 is defined to include a brush body 122. Specifically, the brush body 122 is rotatably connected to the housing 110, and a plurality of implanted hairs 121 are arranged at intervals on the brush body 122. When the floor brush assembly 100 is in a working state, the brush body 122 drives the plurality of implanted hairs 121 to rotate relative to the housing 110 to clean the surface to be cleaned. By arranging a plurality of implanted hairs 121 at intervals on the brush body 122, it is convenient for the roller brush 120 to pick up debris on the surface to be cleaned, thereby improving the cleaning effect of the vacuum cleaner having the floor brush assembly 100.

[0070] When at least one comb tooth 131 is inserted between any two adjacent implanted bristles 121, along the radial direction of the roller brush 120, the width of the gap 150 between one end of the comb tooth 131 facing the brush body 122 and the outer wall of the brush body 122 is less than or equal to a preset value. That is, when at least one comb tooth 131 is inserted between two adjacent implanted bristles 121, the gap 150 between the inserted end of the comb tooth 131 and the outer wall of the brush body 122 is smaller, thereby further shortening the distance between the comb tooth 131 and the hair or other fabrics wrapped around the outer wall of the brush body 122. Further, under the combing of the comb tooth structure 130, the hair or other fabrics wrapped around the outer wall of the brush body 122 can pass over the implanted bristles 121 and be sucked away, thereby improving the anti-entanglement effect of the floor brush assembly 100.

[0071] Optionally, the brush body 122 is a cylinder, or the cylinder is concave in the middle of the axial direction. The specific configuration can be based on actual needs.

[0072] like Figure 3 As shown, in some embodiments, optionally, along the radial direction of the roller brush 120 , the width h of the gap 150 satisfies 0 mm<h≤1 mm.

[0073] In this embodiment, the width of the gap 150 in the radial direction of the roller brush 120 is defined. Specifically, the width of the gap 150 is less than or equal to 1 mm and greater than 0 mm. That is, when at least one comb tooth 131 is inserted between two adjacent implanted hairs 121, there is a gap 150 between the insertion end of the comb tooth 131 and the outer wall of the brush body 122, and the width of the gap 150 is small. Thus, while further improving the anti-entanglement capability of the roller brush 120, the manufacturing difficulty of the comb tooth structure 130 can be reduced, thereby reducing the production cost of the floor brush assembly 100.

[0074] It is understandable that if the width of the gap 150 along the radial direction of the roller brush 120 is large, that is, h is greater than 1 mm, the comb teeth 131 inserted between two adjacent implanted hairs 121 cannot touch the hair and other fabrics wrapped around the brush body 122, making it impossible for hair and other fabrics to pass over the implanted hairs 121. After long-term use, it is necessary to clean the debris on the roller brush 120, affecting the user experience.

[0075] In some embodiments, optionally, along the radial direction of the roller brush 120 , the width of the gap 150 is equal to 0 mm.

[0076] In this embodiment, the width of the gap 150 in the radial direction of the roller brush 120 is limited to 0 mm, that is, when at least one comb tooth 131 is inserted between two adjacent implanted hairs 121, the insertion end of the comb tooth 131 just contacts the outer wall of the brush body 122, so that the comb tooth 131 inserted between two adjacent implanted hairs 121 can fully contact the hair and other fabrics wrapped around the outer wall of the brush body 122, so that the hair and other fabrics can quickly pass over the implanted hairs 121 and be sucked in, thereby significantly improving the anti-entanglement effect.

[0077] Optionally, along the radial direction of the roller brush 120, the distance between the inner wall of the housing 110 where the comb teeth 131 are located and the outer wall of the brush body 122 is smaller than the length of the comb teeth 131, that is, the comb teeth 131 inserted between two adjacent implanted hairs 121 are in contact with the outer wall of the brush body 122, and the insertion end of the comb teeth 131 is partially bent, that is, the comb teeth 131 and the outer wall of the brush body 122 are interference fit, thereby improving the anti-entanglement effect of the floor brush assembly 100. It is understandable that during the rotation of the roller brush 120 relative to the housing 110, the outer wall of the brush body 122 will grind off the interference part of the comb teeth 131.

[0078] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, optionally, the outer wall of the brush body 122 is provided with a groove 123 , and at least one implanted hair 121 is located in the groove 123 .

[0079] In this embodiment, a groove 123 is provided on the outer wall of the brush body 122. Specifically, at least one implanted hair 121 is located in the groove 123. Under the premise that the implanted hair 121 protrudes from the outer wall of the brush body 122 by a certain length, the length of at least one implanted hair 121 is increased, that is, the distance between the root of the implanted hair 121 and the outer wall of the brush body 122 is increased, thereby lengthening the cantilever of the implanted hair 121, thereby reducing the blocking force of the implanted hair 121 on the hair and other fabrics entangled on the outer wall of the brush body 122 to move toward the air suction port 112, so that the hair and other fabrics can be quickly sucked over the implanted hair 121 under the combing of the comb tooth structure 130, thereby further improving the anti-entanglement effect of the floor brush assembly 100, and no regular manual cleaning is required, thereby improving the user experience.

[0080] Moreover, by setting at least one implanted hair 121 in the groove 123, it is also possible to effectively prevent hair and other fabrics from being entangled in the roots of the implanted hair 121, thereby making it difficult to move the hair and other fabrics, thereby improving the anti-entanglement effect of the floor brush assembly 100.

[0081] Optionally, a plurality of implanted bristles 121 are located in the groove 123 to further improve the anti-entanglement effect of the floor brush assembly 100 .

[0082] In some embodiments, optionally, the rotation speed P of the roller brush 120 satisfies 2000 rpm≤P≤5000 rpm.

[0083] In this embodiment, the rotation speed of the roller brush 120 is limited to between 2000rpm and 5000rpm. That is, the rotation speed of the roller brush 120 relative to the housing 110 is increased, so that hair and other fabrics can be thrown out from the surface of the brush body 122 under the action of centrifugal force. Even if there is a gap 150 between the insertion end of the comb teeth 131 and the outer wall of the brush body 122, the centrifugal force can be used to make the comb teeth 131 touch the hair and other fabrics wrapped around the brush body 122, further improving the anti-entanglement ability of the roller brush 120, eliminating the need for manual cleaning, and improving the convenience of use for users.

[0084] It is understandable that if the rotation speed of the roller brush 120 is too high, that is, P is greater than 5000 rpm, the load requirement for the motor driving the roller brush 120 to rotate is higher, and the noise of the floor brush assembly 100 during operation is also greater.

[0085] In some embodiments, optionally, along the axial direction of the roller brush 120 , the distance between any two adjacent implanted hairs 121 is greater than the width of at least one comb tooth 131 .

[0086] In this embodiment, the axial spacing between any two adjacent implanted bristles 121 is limited to be greater than the axial width of at least one comb tooth 131, so that when the roller brush 120 rotates relative to the shell 110, at least one comb tooth 131 can be inserted between any two adjacent implanted bristles 121 to comb the hair and other fabrics wrapped around the outer wall of the brush body 122, thereby further improving the anti-entanglement capability of the roller brush 120 and reducing the amount of entanglement of hair and other fabrics on the roller brush 120 after long-term use of the roller brush 120. There is no need for the user to manually clean it, thereby improving the user's convenience and further improving the user's experience.

[0087] Moreover, compared with the related art in which the hair entanglement effect is reduced by adding structures such as leather strips or blades, the structure is simple and the production cost of the floor brush assembly 100 can be significantly reduced.

[0088] like Figure 1 and Figure 4 As shown, in some embodiments, optionally, a plurality of implanted bristles 121 arranged axially at intervals along the roller brush 120 form a implanted bristle assembly 140, and the implanted bristle assembly 140 extends in a circumferential spiral along the roller brush 120; and / or a plurality of comb teeth 131 are arranged axially at intervals along the roller brush 120.

[0089] In this embodiment, a plurality of implanted hairs 121 arranged at intervals in the axial direction of the roller brush 120 are formed into a implanted hair assembly 140, that is, a plurality of implanted hairs 121 in the implanted hair assembly 140 are arranged at intervals in the axial direction of the roller brush 120. The implanted hair assembly 140 extends in a circumferential spiral along the roller brush 120, that is, the outer wall of the brush body 122 has spirally implanted hairs 121.

[0090] Specifically, when using a vacuum cleaner with a floor brush assembly 100 to clean hair, the hair will be partially entangled on the brush body 122. At this time, under the negative pressure of the vacuum cleaner, the hair will tend to converge toward the middle air inlet 112, and the hair will make a spiral movement toward the middle under the negative pressure, but the implanted hair 121 on the roller brush 120 will prevent the hair from moving toward the middle air inlet 112. The rotating roller brush 120 is combed by the multiple comb teeth 131 of the comb tooth structure 130, and the hair passes over the implanted hair 121 to make the spiral movement proceed smoothly. Finally, the hair converges to the middle air inlet 112 and is sucked into the vacuum cleaner and enters the collection chamber of the vacuum cleaner.

[0091] A plurality of comb teeth 131 are arranged at intervals along the axial direction of the roller brush 120. Since a plurality of implanted bristles 121 are arranged at intervals along the axial direction of the roller brush 120, more comb teeth 131 can be inserted between two adjacent implanted bristles 121 during the rotation of the roller brush 120 relative to the shell 110, so that hair and other fabrics entangled on the outer wall of the brush body 122 can be fully cleaned, further improving the anti-entanglement ability of the floor brush assembly 100.

[0092] like Figure 1 As shown, in some embodiments, optionally, the housing 110 is further provided with an air suction port 112 , which is in communication with the working chamber 111 , and at least a portion of the air suction port 112 is opposite to the middle portion of the roller brush 120 in the axial direction.

[0093] In this embodiment, it is defined that the housing 110 is also provided with an air suction port 112. Specifically, the air suction port 112 is connected to the working chamber 111, and at least a part of the air suction port 112 is opposite to the middle part of the roller brush 120 in the axial direction. Specifically, the roller brush 120 includes a first end and a second end that are opposite to each other in the axial direction, and the middle part of the roller brush 120 is located between the first end and the second end, and the axial distance between the middle part and the first end is equal to the axial distance between the middle part and the second end. The air suction port 112 is opposite to the middle part of the roller brush 120, so that it is convenient to suck away particles and other debris entering the working chamber 111 and fabrics such as hair wrapped around the outer wall of the brush body 122 through the air suction port 112.

[0094] like Figure 2 As shown, in some embodiments, optionally, the housing 110 is further provided with an opening 113 , the opening 113 is communicated with the working chamber 111 , and at least a portion of at least one implanted hair 121 is exposed to the working chamber 111 through the opening 113 .

[0095] In this embodiment, the shell 110 is further provided with an opening 113. Specifically, the opening 113 is connected to the working chamber 111, and at least a portion of at least one implanted hair 121 is exposed to the working chamber 111 through the opening 113, thereby improving the cleaning effect of the surface to be cleaned and improving the dust removal efficiency.
