Technical Field

[0002] The present application relates to the technical field of vacuum cleaners, and in particular to a floor brush of a vacuum cleaner and a vacuum cleaner. Background Art

[0003] At present, when a vacuum cleaner completes its cleaning work, hair, thin wires and other slender objects are usually entangled on the roller brush. In order to solve the problem of slender objects entangled on the roller brush, the relevant technology adopts a method of rotating the roller brush and the sleeve at the same speed on the offset shaft. Then, when the roller brush and the sleeve rotate, the bristles can move in and out of the sleeve. However, due to the limitation of the offset amount, a small amount of slender objects will still be stuck in the bristles of the roller brush.

[0004] Summary of the Invention

DETAILED DESCRIPTION

[0042] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0044] The following describes a floor brush 100 and a vacuum cleaner provided according to some embodiments of the present application with reference to FIG. 1 to FIG. 11 .

[0045] As shown in Figures 1, 2, 3 and 4, according to the first aspect of the present application, the present application provides a floor brush 100 for a vacuum cleaner, comprising: a shell 110, a sleeve 122, a roller brush 130 and a foreign matter removal portion 116, a first mounting groove 112 is provided on the shell 110, the sleeve 122 is rotatably disposed in the first mounting groove 112, and a center hole 1222 is provided on the sleeve 122 which passes through the axial direction of the sleeve 122, the roller brush 130 is disposed in the center hole 1222 of the sleeve 122, and the roller brush 130 is rotatable.

[0046] In addition, a through hole 126 is provided on the cylindrical wall 124 of the sleeve 122, and the roller brush 130 includes a brush body 132 and a bristle portion 136 provided on the brush body 132. The bristle portion 136 is distributed on the peripheral side wall 134 of the brush body 132, and the bristle portion 136 and the through hole 126 are arranged opposite to each other.

[0047] As shown in FIG2 , the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 are staggered, that is, the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 do not coincide, and the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 can be roughly parallel, and the bristle portion 136 on the roller brush 130 and the through hole 126 on the sleeve 122 are opposite, and when the roller brush 130 and the sleeve 122 rotate, the track drawn by the outermost circle of the bristle portion 136 forms a circle, and the track of the outermost circle of the sleeve 122 is not equal to the track of the outermost circle of the sleeve 122. The two circles intersect, and the bristle portion 136 can extend from the sleeve 122 through the same through hole 126 starting from the first position where the two circular trajectories intersect, and continuously increase the length of the bristle portion 136 extending from the sleeve 122. After the length of the bristle portion 136 extending from the sleeve 122 reaches a maximum, it begins to retract into the sleeve 122 and continuously reduces the length of the bristle portion 136 extending from the sleeve 122. Finally, the bristle portion 136 can be retracted into the sleeve 122 from the second position of the two circular trajectories. The staggered arrangement of the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 includes: the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 are substantially parallel, or the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 intersect.

[0048] As described above, during the extension and retraction of the bristle portion 136, foreign matter on the bristle portion 136 will be blocked by the edge of the through hole 126, so that at least part of the foreign matter remains outside the sleeve 122. The housing 110 is further provided with a foreign matter removal portion 116, which is used to scrape foreign matter outside the sleeve 122. That is, the foreign matter removal portion 116 can catch foreign matter outside the sleeve 122 blocked by the edge of the through hole 126. Then, as the roller brush 130 continues to rotate, the foreign matter entangled on the bristle portion 136 can be pulled out of the bristle portion 136, thereby cleaning the roller brush 130 and reducing the possibility of foreign matter entangled on the roller brush 130. The foreign matter can be a slender object such as hair, animal hair or thread.

[0049] The floor brush 100 of the vacuum cleaner further includes a driving assembly for driving the sleeve 122 and the roller brush 130 to rotate. Specifically, the driving assembly includes a first driving member and a second driving member. The first driving member drives the roller brush 130 to rotate, and the second driving member drives the sleeve 122 to rotate, thereby respectively driving the roller brush 130 and the sleeve 122. The first driving member can be a first motor, and the second driving member can be a second motor.

[0050] Alternatively, the drive assembly includes a drive member, a first transmission member, and a second transmission member. The drive member can drive the first transmission member and the second transmission member to move. The first transmission member can drive the roller brush 130 to rotate, and the second transmission member can drive the sleeve 122 to rotate, thereby achieving separate driving of the roller brush 130 and the sleeve 122. The first transmission member can be a first gear, and the second transmission member can be a second gear, or the first transmission member can be a first belt, and the second transmission member can be a second belt.

[0051] The floor brush 100 of the vacuum cleaner provided in the present application includes a shell 110, a sleeve 122, a roller brush 130 and a foreign matter removal part 116. The shell 110 has a first mounting groove 112, the sleeve 122 is rotatably arranged in the first mounting groove 112, the roller brush 130 is rotatably arranged in the sleeve 122, and the sleeve 122 includes a barrel wall 124 and a through hole 126, and the through hole 126 is arranged on the barrel wall 124.

[0052] The roller brush 130 includes a brush body 132 and a bristle portion 136 . The bristle portion 136 is disposed on the peripheral side wall 134 of the brush body 132 . The bristle portion 136 protrudes from the brush body 132 and is disposed opposite the through hole 126 . Thus, the bristle portion 136 can extend from and retract into the sleeve 122 through the through hole 126 .

[0053] As shown in Figure 2, the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 are staggered, that is, the rotation axis B of the roller brush 130 and the rotation axis A of the sleeve 122 do not overlap, and then when the roller brush 130 and the sleeve 122 rotate, the bristle portion 136 can start to extend out of the sleeve 122 from the same through hole 126 at the first position, and continuously increase the length of the bristle portion 136 extending out of the sleeve 122. After the length of the bristle portion 136 extending out of the sleeve 122 reaches the maximum, it begins to retract into the sleeve 122 and continuously reduces the length of the bristle portion 136 extending out of the sleeve 122. Finally, in the second position, the bristle portion 136 can be retracted into the sleeve 122.

[0054] At the opening of the first mounting groove 112, the bristle portion 136 extends out of the sleeve 122, and can then clean the surface to be cleaned. When the bristle portion 136 retracts into the sleeve 122, the edge of the through hole 126 can scrape off foreign matter on the bristle portion 136, so that the foreign matter stays on the outside of the sleeve 122. When the foreign matter passes through the foreign matter removal portion 116, the foreign matter removal portion 116 can hook the foreign matter, and with the continued rotation of the roller brush 130 and the sleeve 122, the foreign matter is separated from the roller brush 130 and stays on the foreign matter removal portion 116, thereby achieving cleaning of the roller brush 130 and reducing the possibility of foreign matter being entangled on the roller brush 130.

[0055] The foreign body removal part 116 can be fixed to the shell 110 by screws, or fixed to the shell 110 by slots and buckles. The foreign body removal part 116 can also be inserted into the shell 110, or pre-embedded in the shell 110. The foreign body removal part 116 and the shell 110 can be an integrated structure, etc.

[0056] For example, there may be a plurality of bristle portions 136 , and the plurality of bristle portions 136 are distributed on the peripheral side wall 134 of the roller brush 130 and correspond to the through holes 126 .

[0057] As shown in FIG2 , in some embodiments, for example, the minimum distance C between the end of the foreign matter removing portion 116 away from the housing 110 and the sleeve 122 is no greater than 2 mm. That is, the end of the foreign matter removing portion 116 close to the sleeve 122 may abut against the sleeve 122, that is, the minimum distance between the end of the foreign matter removing portion 116 close to the sleeve 122 and the sleeve 122 is equal to 0, or there is a certain gap between the end of the foreign matter removing portion 116 close to the sleeve 122 and the sleeve 122, and the minimum distance between the end of the foreign matter removing portion 116 close to the sleeve 122 and the sleeve 122 is greater than 0 and less than or equal to 2 mm.

[0058] In this embodiment, the end of the foreign matter removal portion 116 away from the sleeve 122 is connected to the shell 110, and the minimum distance C between the end close to the sleeve 122 and the sleeve 122 is not greater than 2 mm, that is, greater than or equal to 0, and less than or equal to 2 mm. Therefore, the distance between the foreign matter removal portion 116 and the sleeve 122 is small, so that the foreign matter removal portion 116 and the sleeve 122 can clamp foreign matter, thereby improving the cleaning effect of the foreign matter removal portion 116 on foreign matter on the roller brush 130, further reducing the possibility of foreign matter being entangled on the roller brush 130, and reducing the noise of the vacuum cleaner.

[0059] Specifically, the minimum distance C between the end of the foreign matter removing portion 116 close to the sleeve 122 and the sleeve 122 may be 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, or 2 mm.

[0060] The foreign matter removing portion 116 may be disposed facing all of the through holes 126 or may be disposed facing part of the through holes 126 .

[0061] As shown in Figures 3, 4, 6, 7 and 8, in some embodiments, exemplarily, an air intake hole 114 is further provided on the shell 110, and the air intake hole 114 is connected to the first mounting groove 112, wherein the foreign matter removal part 116 is provided at a position where the air intake hole 114 and the first mounting groove 112 are connected, and partially blocks the air intake hole 114.

[0062] In this embodiment, the shell 110 includes an air suction hole 114, which is connected to the first mounting groove 112. The foreign matter removal part 116 partially blocks the air suction hole 114. After the foreign matter removal part 116 scrapes off the foreign matter, the air suction hole 114 can suck away the foreign matter, ensuring the cleaning effect of the vacuum cleaner and reducing the possibility of foreign matter being entangled on the roller brush 130.

[0063] Specifically, the suction hole 114 is arranged at the middle position of the first installation groove 112, so that foreign matter can be evenly sucked.

[0064] As shown in FIG. 7 , in some embodiments, illustratively, comb teeth 120 are formed on a side of the foreign matter removing portion 116 facing the sleeve 122 , and the comb teeth 120 face the sleeve 122 .

[0065] In this embodiment, comb teeth 120 are formed on the side of the foreign matter removal portion 116 facing the sleeve 122, and the comb teeth 120 face the sleeve 122. The comb teeth 120 and the foreign matter removal portion 116 make it easier to scrape off foreign matter on the roller brush 130, further reducing the possibility of foreign matter being entangled on the roller brush 130.

[0066] Specifically, the number of the comb teeth 120 is multiple, and the comb teeth 120 are arranged facing the gaps between the bristles, so as to facilitate the hooking of foreign matter out of the bristle portion 136. The comb teeth 120 can be a needle-like structure or a sheet-like structure.

[0067] The comb teeth 120 include a plurality of teeth arranged side by side, and the teeth are spaced apart so as to be inserted into the gaps between the bristles. The minimum distance C between the teeth of the comb teeth 120 and the sleeve 122 is greater than 0 and less than or equal to 2 mm. The teeth can be directly provided on the housing 110, or the foreign matter removal portion 116 further includes a connecting portion, one end of the connecting portion being connected to the housing 110 and the other end being connected to the teeth.

[0068] As shown in FIG. 8 and FIG. 9 , in some embodiments, the foreign matter removing portion 116 illustratively includes a blade 128 , and an edge portion 1282 of the blade 128 faces away from the housing 110 .

[0069] In this embodiment, the foreign matter removing portion 116 includes a blade 128 , and an edge portion 1282 of the blade 128 faces away from the housing 110 , so that the blade 128 can cut off foreign matter, further reducing the possibility of foreign matter being entangled on the roller brush 130 .

[0070] The blade 128 may be made of metal, such as iron, iron alloy, copper, copper alloy, plastic, or ceramic.

[0071] As shown in FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , in some embodiments, illustratively, the foreign matter removing portion 116 and the housing 110 are an integrated structure.

[0072] In this embodiment, the foreign matter removal unit 116 and the housing 110 are an integrated structure, which eliminates the need for assembling the foreign matter removal unit 116 and the housing 110 and improves production efficiency.

[0073] Specifically, the foreign matter removing portion 116 and the housing 110 may be made of plastic, and the housing 110 may be made of a transparent material. The foreign matter removing portion 116 and the housing 110 are injection molded.

[0074] As shown in Figures 3, 4, 10 and 11, in some embodiments, exemplarily, the roller brush 130 also includes a covering member 138 arranged on the brush body 132, and the covering member 138 protrudes from the brush body 132 by the peripheral side wall 134 of the brush body 132, and the covering member 138 and the bristle portion 136 are distributed along the circumference of the brush body 132. When the sleeve 122 and the roller brush 130 rotate, the bristle portion 136 and the covering member 138 can extend out of and retract into the sleeve 122 through the through hole 126.

[0075] In this embodiment, the roller brush 130 includes a brush body 132, a bristle portion 136 and a shielding member 138, which are arranged on the peripheral side wall 134 of the brush body 132 and protrude from the brush body 132, wherein the shielding member 138 and the bristle portion 136 are distributed along the circumference of the brush body 132, that is, when the brush body rotates along the rotation direction W, the surface to be cleaned contacts the shielding member 138 and the bristle portion 136 in turn. Specifically, the shielding member 138 may contact the surface to be cleaned first, or the bristle portion 136 may contact the surface to be cleaned first. The shielding member 138 and the bristle portion 136 are arranged opposite to the same through hole 126, and then the bristle portion 136 and the shielding member 138 can extend out and retract into the sleeve 122 through the same through hole 126.

[0076] When the roller brush 130 and the sleeve 122 rotate, the bristle portion 136 and the covering member 138 can start to extend out of the sleeve 122 from the same through hole 126 at the first position, and continue to increase the length of the bristle portion 136 and the covering member 138 extending out of the sleeve 122. After the length of the bristle portion 136 and the covering member 138 extending out of the sleeve 122 reaches the maximum, they begin to retract into the sleeve 122 and continue to reduce the length of the bristle portion 136 and the covering member 138 extending out of the sleeve 122. Finally, at the second position, the bristle portion 136 and the covering member 138 can be retracted into the sleeve 122.

[0077] At the opening of the first mounting groove 112, the bristle portion 136 and the shielding member 138 extend out of the sleeve 122, so that the surface to be cleaned can be cleaned. Moreover, since the shielding member 138 is arranged on one side of the bristle portion 136, the depth of foreign matter on the bristle portion 136 entering the bristle portion 136 can be reduced. On the inner side of the first mounting groove 112, the bristle portion 136 and the shielding member 138 are retracted into the sleeve 122, so that the edge of the through hole 126 can scrape off foreign matter on the bristle portion 136. Combined with the foreign matter removing portion 116, the foreign matter can be scraped off, thereby further improving the cleaning effect of the roller brush 130 and reducing the possibility of foreign matter being entangled on the roller brush 130.

[0078] As mentioned above, the shielding member 138 and the bristle portion 136 move synchronously, and when a foreign object wants to penetrate into the bristle portion 136, it will be blocked by the shielding member 138, and the foreign object can only enter a small part of the bristle portion 136, reducing the entanglement binding force between the foreign object and the bristle portion 136, and then when the foreign object removal portion 116 hooks the foreign object, the foreign object can smoothly break away from the bristle portion 136.

[0079] Moreover, along the rotation direction W of the roller brush 130, the bristle portion 136 is located in front of the shielding member 138, which makes it easier for the bristle portion 136 to clean foreign matter. That is, during cleaning, among a pair of bristle portions 136 and the shielding member 138, the bristle portion 136 first contacts the surface to be cleaned.

[0080] As shown in FIG. 3 , FIG. 4 and FIG. 11 , in some embodiments, illustratively, the shielding member 138 is embedded in the brush body 132 .

[0081] In this embodiment, the shielding member 138 is embedded in the brush body 132 , thereby increasing the connection strength between the shielding member 138 and the brush body 132 .

[0082] Specifically, the shielding member 138 can be assembled with the housing 110 by insert injection molding.

[0083] As shown in Figures 4 and 11, in some embodiments, for example, the covering member 138 includes a limiting portion 140 and a protrusion 142, the limiting portion 140 is buried in the brush body 132, the protrusion 142 is arranged on the limiting portion 140, and protrudes from one side of the limiting portion 140, and the protrusion 142 protrudes from the brush body 132 by the peripheral side wall 134 of the brush body 132, and the protrusion 142 and the bristle portion 136 are distributed along the circumference of the brush body 132.

[0084] In this embodiment, the shielding member 138 includes a limiting portion 140 and a protrusion 142. The limiting portion 140 is embedded in the brush body 132, and the protrusion 142 is arranged on the limiting portion 140 and protrudes from the brush body 132. In addition, the protrusion 142 and the bristle portion 136 are distributed along the circumference of the brush body 132, that is, when the brush body rotates along the rotation direction W, the surface to be cleaned contacts the protrusion 142 and the bristle portion 136 in turn. Specifically, the protrusion 142 may contact the surface to be cleaned first, or the bristle portion 136 may contact the surface to be cleaned first. Foreign matter is blocked by the protrusion 142, and the possibility of foreign matter being entangled in the roller brush 130 is reduced. In addition, the limiting portion 140 increases the connection strength between the shielding member 138 and the brush body 132, and the possibility of the shielding member 138 detaching from the brush body 132 is reduced.

[0085] The width of the protruding portion 142 is smaller than the width of the limiting portion 140 .

[0086] In some embodiments, for example, the shielding member 138 is an elastic shielding member, and the shielding member 138 can be bent along a rotation direction away from the brush body 132 .

[0087] In this embodiment, the shielding member 138 is an elastic shielding member, which can be bent along the rotation direction of the brush body 132. Therefore, when the bristle portion 136 cleans the surface to be cleaned, the shielding member 138 and the bristle portion 136 can be bent to ensure the cleaning effect.

[0088] Specifically, the shielding member 138 can be made of rubber, silicone, leather, etc.

[0089] As shown in Figure 4, taking the rotation of the brush body 132 along the rotation direction W as an example, the covering member 138 can be bent in the direction away from W, and then when the floor brush 100 of the vacuum cleaner is working, the brush body 132 rotates, and the covering member 138 and the bristle portion 136 contact the surface to be cleaned, thereby bending in the direction away from W, thereby increasing the contact area between the bristle portion 136 and the surface to be cleaned, and improving the cleaning effect of the vacuum cleaner.

[0090] As shown in Figure 11, in some embodiments, for example, the bristle portion 136 protrudes from the brush body 132, and the height of the protrusion of the bristle portion 136 is a first height D, the covering member 138 protrudes from the brush body 132, and the height of the protrusion of the covering member 138 is a second height E, the first height D is equal to the second height E, that is, the difference between the first height D and the second height E is equal to 0, or the first height D is not less than the second height E, and the difference between the first height D and the second height E is greater than 0 and less than or equal to 3 mm.

[0091] In this embodiment, the height of the bristle portion 136 protruding from the brush body 132 is a first height D, and the height of the shielding member 138 protruding from the brush body 132 is a second height E. The first height D is equal to the second height E, or the first height D is greater than the second height E, and the difference between the first height D and the second height E is less than or equal to 3 mm, so as to ensure that the bristle portion 136 can clean the surface to be cleaned and improve the cleaning effect of the vacuum cleaner.

[0092] Specifically, the difference between the first height D and the second height E may be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm.

[0093] In some embodiments, for example, along the rotation direction W of the roller brush 130, the distance between the bristle portion 136 and the shielding member 138 is less than or equal to 20 mm. Specifically, the distance between the two can be determined according to the diameter of the brush body 132, for example: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 10 mm, 15 mm or 20 mm, etc.

[0094] As shown in FIG. 10 , in some embodiments, for example, there are multiple through holes 126 and multiple blocking members 138 , and at least one bristle portion 136 can extend out of and retract into the sleeve 122 through one through hole 126 .

[0095] In this embodiment, there are multiple through holes 126, and the multiple through holes 126 are distributed on the barrel wall 124 of the sleeve 122. When the roller brush 130 and the sleeve 122 rotate, there is always a through hole 126 located at the opening of the first mounting groove 112, thereby ensuring the dust collection effect of the vacuum cleaner.

[0096] There are multiple bristle parts 136, and the multiple bristle parts 136 are spaced apart and distributed on the peripheral side wall 134 of the brush body 132. There are multiple through holes 126, and the multiple through holes 126 are spaced apart and distributed on the cylindrical wall 124 of the sleeve 122. The multiple bristle parts 136 are respectively arranged in a one-to-one correspondence with the multiple through holes 126.

[0097] As shown in Figure 10, in some embodiments, for example, there are multiple through holes 126, multiple covering members 138, and multiple bristle portions 136, and at least one covering member 138 and at least one bristle portion 136 can extend out and retract into the sleeve 122 through a through hole 126.

[0098] In this embodiment, there are multiple through holes 126, and the multiple through holes 126 are distributed on the sleeve 122, so that when the roller brush 130 and the sleeve 122 rotate, there is always a through hole 126 located at the opening of the first mounting groove 112, thereby ensuring the dust collection effect of the vacuum cleaner.

[0099] There are multiple bristle portions 136, and the multiple bristle portions 136 are spaced apart and distributed on the peripheral side wall 134 of the brush body 132. There are multiple shielding members 138, and the multiple shielding members 138 are spaced apart and distributed on the peripheral side wall 134 of the brush body 132. One bristle portion 136 corresponds to one or more shielding members 138, that is, one side of one bristle portion 136 is provided with one or more shielding members 138. There are multiple through holes 126, and the multiple through holes 126 are spaced apart and distributed on the cylindrical wall 124 of the sleeve 122. The multiple bristle portions 136 and the multiple shielding members 138 correspond one to one with the multiple through holes 126 respectively.

[0100] The bristle portion 136 includes multiple tufts of bristles, which are arranged adjacent to each other and arranged in a strip-like configuration. The shielding member 138 is a strip-like structure. The shielding member 138 and the bristle portion 136 extend in the same direction and can be arranged substantially parallel to each other, or the bristle portion 136 and the shielding member 138 can both be arranged in a similar arc shape. Specifically, the bristle portion 136 can include one row of bristles or multiple rows of bristles.

[0101] The through hole 126 also has a strip-shaped structure. The size of the through hole 126 can be slightly larger than the bristle portion 136 and the shielding member 138 , so as to facilitate the bristle portion 136 and the shielding member 138 to extend and retract through the same through hole 126 .

[0102] The bristle portion 136 and the shielding member 138 are arranged to face the through hole 126 .

[0103] The through hole 126 spirally extends from one end of the sleeve 122 along the cylindrical wall 124 of the sleeve 122 to the other end, and the bristles 136 are configured to follow the shape of the through hole 126 and are spirally arranged on the peripheral side wall 134 of the brush body 132. Through this arrangement, the bristles 136 are provided along the entire length of the brush body 132. When the brush body 132 rotates continuously, the surface to be cleaned below the floor brush 100 of the vacuum cleaner can be cleaned without blind spots. During the rotation process, the bristles 136 always extend from the through hole 126 at the bottom of the floor brush 100 of the vacuum cleaner, thereby continuously cleaning the surface to be cleaned, avoiding idling and achieving a more stable cleaning effect.

[0104] Furthermore, two groups of spirally arranged through holes 126 are provided on the sleeve 122 , one group being distributed in a clockwise direction and the other group being distributed in a counterclockwise direction.
