Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

Fig. 1 to 6 show the configuration of a roll brush assembly of an embodiment. The rolling brush component is suitable for a dust collector or a floor washing machine.

Referring to fig. 1, the present roll brush assembly 10 includes a brush body 11 and a holder 12. The holder 12 is mounted on a support shaft 111 at one end of the brush body 11, and the holder 12 has a handle portion 121. The left end of the brush body 11 is conveniently pushed or pulled down by the handle portion 121 of the holder 12 to attach or detach the roll brush to or from an apparatus, such as a floor washer or a vacuum cleaner.

Referring to fig. 2, brush body 11 has a support shaft 111 at the center of its left end, and holder 12 is attached to support shaft 111 and fixed to support shaft 111 by elastic retainer 13. The brush body 11 is provided with a first protruding ring 112 at a position around the supporting shaft 111, and the holder 12 has a first retaining ring 122 extending toward the brush body 11.

With further reference to fig. 3, the outer diameter of the first protruding ring 112 gradually increases in a direction from right to left, that is, in a direction away from the brush body 11.

With further reference to fig. 4 and 5, the distal end of the first retainer ring 122 extends to a position opposite the outer peripheral wall of the first male ring 112.

Referring to fig. 5, when a hair-like object falls off from the left end of the brush body 11 after the first protruding ring 112 and the first retaining ring 122 are provided, the hair-like object falls on the first retaining ring 122 and the first protruding ring 112, and is hard to enter the gap h3 between the left end of the brush body 11 and the holder 12. Further, the above-described structural feature of the outer diameter of the first projecting ring 112 allows hair-like objects falling thereon to be guided rightward, i.e., closer to the brush body 11, and away from the gap h3 between the left end of the brush body 11 and the holder 12, whereby the hair-like objects are better prevented from entering the gap h3 between the left end of the brush body 11 and the holder 12 and from being wound around the support shaft 111.

Referring to fig. 2, 4 and 6, the brush body 11 has a driving connection portion 114 at the right end center, and the driving connection portion 114 is used for cooperating with the driving head 26 (see fig. 9) on the floor brush body 21 to drive the brush body 11 to rotate. The brush body 11 is provided with a second protruding ring 113 at a position around the outer end of the drive connection portion 114. The second protruding ring 113 has the same structure as the first protruding ring 112, and both are arranged in a mirror image. The second protruding ring 113 is used to carry hair-like objects falling from the right end of the brush body 11, prevent them from falling into the gap at the right end of the brush body 11, and wind around the driving head 26, as the first protruding ring 112 functions.

Therefore, the arrangement of the first convex ring 112, the second convex ring 113 and the first baffle ring 122 can prevent hair objects falling from two ends of the brush body 11 from being wound around the supporting shaft 111 and the driving head 26, thereby greatly improving the problem that the rolling brush is blocked due to the hair objects entering between the shaft and the bearing at the left end and the right end of the rolling brush.

Referring further to fig. 5, the outer diameter of the first stopper ring 122 is gradually decreased in a left-to-right direction, i.e., in a direction approaching the brush body 11. With this structure, the hair-like objects falling from the left end of the brush body 11 to the first stopper ring 122 are guided to move in the direction to the right in fig. 5, and fall onto the first male ring 112 through the gap h2 between the first stopper ring 122 and the brush body 11. Since the holder 12 is stationary and the brush body 11 is in the revolving motion during use, if a part of the hair-like objects is wound around the brush body 11 and another part is wound around the first ring 122 on the holder 12, the revolving motion of the brush body 11 is hindered. Due to the structural feature of the first retaining ring 122, the hair-like objects on the first retaining ring 122 can be guided to the first protruding ring 112, so that the obstruction of the rotation of the brush body 11 caused by such phenomenon can be greatly improved.

Preferably, the outer peripheral wall of the first retaining ring 122, the outer peripheral wall of the first protruding ring 112, and the outer peripheral wall of the second protruding ring 113 are conical surfaces with a taper larger than 15 degrees. With the angle characteristic, the hair objects on the hair guiding device are easier to guide and move.

Referring to fig. 4, the brush body 11 includes a spindle 116 and a cleaning cloth 115, and the cleaning cloth 115 is fixed on the outer surface of the spindle 116 for wiping the ground when the brush body 11 rotates. It should be noted that the wipe 115 of the present application refers broadly to all types of materials that may be used to wipe a floor. The first convex ring 112 and the second convex ring 113 are specifically arranged on the mandrel 116, and the outer diameter of the first convex ring 112 and the outer diameter of the second convex ring 113 are both larger than the outer diameter of the mandrel 116, so that the first convex ring 112 and the second convex ring 113 also have a limiting effect on the cleaning cloth 115, and the cleaning cloth 115 can be prevented from moving along the axial direction of the mandrel 116.

With further reference to fig. 5, a gap h1 between the inner wall of the first baffle ring 122 and the outer wall of the leftmost end of the first protruding ring 112, i.e., a minimum gap between the inner wall of the first baffle ring 122 and the outer wall of the first protruding ring 112, is smaller than a gap h2 between the end of the first baffle ring 122 and the end of the cleaning cloth 115. This makes it more difficult for the hair-like objects to pass through the gap h1 between the first stopper ring 122 and the first protruding ring 112, and to be better prevented from being wound around the support shaft 111.

In this embodiment, the bracket 12 and the support shaft 111 are engaged by a bearing 1111.

Fig. 7 to 12 show the construction of an embodiment of a floor brush 20, the local brush 20 being suitable for use in a vacuum cleaner or scrubber.

Referring to fig. 7, 8 and 9, the local brush 20 includes a body 21, a rolling brush installation groove 24 is formed at a front end of the body 21, a cover body 22 is detachably installed at an upper end of the rolling brush installation groove 24, a dust suction flow channel 27 is formed at a rear middle portion of the rolling brush installation groove 24, a flow channel outlet 28 is formed at a top portion of the body 21, and wheels 23 are formed at a bottom portion of the body 21 so that the local brush 20 can move on the floor. When the dust collector works, the brush body 11 rotates to wipe the ground, and the wiped dust and sundries are sucked away from the ground under the action of negative pressure in the dust collection flow channel 27 and enter a garbage container in the host along the dust collection flow channel 27.

With further reference to fig. 8 and 9, the left end of the roll brush installation groove 24 has an installation position (not shown) for engaging with the holder 12 of the roll brush assembly 10, and the right end of the roll brush installation groove 24 has a driving head 26 for driving the roll brush assembly 10 to perform a rotational movement.

The local brush 20 further includes the roll brush assembly 10 of the above-described embodiment. Wherein, the drive connection part 114 at the right end of the rolling brush assembly 10 is aligned and inserted with the drive head 26 at the right end of the rolling brush installation groove 24, and then the left end of the rolling brush is pressed downwards, and the bracket 12 at the left end is inserted into the bracket installation position, thus completing the installation of the rolling brush assembly 10. The removal of the brush roll assembly 10 from the floor brush 20 is completed by grasping the handle portion 121 of the frame 12, pulling the left end of the brush roll upward, and removing the brush roll from the drive head 26 to the left.

As shown in fig. 9, a second stopper ring 25 extending toward the brush is provided in the brush installation groove 24 at a position around the driving head 26.

With further reference to fig. 10 to 12, the distal end of the second retainer ring 25 extends to a position opposite to the outer peripheral wall of the second projecting ring 113. Thus, when a hair-like object falls from the right end of the brush body 11, it falls onto the second stopper ring 25 and the second projecting ring 113, and is difficult to enter the gap between the right end of the brush body 11 and the rolling-brush attachment groove 24. Further, the second projecting ring 113 has such an outer diameter characteristic that the hair-like objects falling thereon are guided to move leftward, i.e., to be close to the brush body 11, and away from the gap between the right end of the brush body 11 and the rolling-brush installation recess 24, whereby the hair-like objects are better prevented from entering the gap between the right end of the brush body 11 and the rolling-brush installation recess 24 and being wound around the driving head 26.

With further reference to fig. 12, the outer diameter of the second retainer ring 25 is gradually reduced in a direction from right to left, i.e., in a direction approaching the brush body 11. Facilitating guiding of hair-like objects to said second collar 113. With this structure, the hair-like objects falling from the right end of the brush body 11 to the second retaining ring 25 are guided to move in the left direction in fig. 12, and fall onto the second projecting ring 113 through the gap between the second retaining ring 25 and the brush body 11. Since the second stopper ring 25 is stationary and the brush body 11 is in the revolving motion during use, if a part of the hair-like objects is wound around the brush body 11 and another part is wound around the second stopper ring 25, the revolving motion of the brush body 11 is hindered. Due to the structural feature of the second retaining ring 25, the hair-like objects on the second retaining ring 25 can be guided to the second protruding ring 113, so that the obstruction of the rotation of the brush body 11 caused by such phenomenon can be greatly improved.

Preferably, the outer peripheral wall of the second retaining ring 25 is a conical surface with a taper larger than 15 degrees. With the angle characteristic, the hair objects on the hair guiding device are easier to guide and move.

The floor scrubber is constructed by combining the floor brush 20 with the body of the floor scrubber.

The floor brush 20 is combined with the body of the cleaner to form the cleaner.

It can be seen from the foregoing that, through setting up first bulge loop 112, second bulge loop 113 at the round brush, set up first fender ring 122 at the support 12 of round brush tip, set up second fender ring 25 at round brush mounting groove 24, through the cooperation of first bulge loop 112 with first fender ring 122, and the cooperation of second bulge loop 113 with second fender ring 25, the round brush that leads to between the axle that has improved greatly because of hair class object gets into the round brush left and right sides both ends and bearing is blocked dead problem, can improve user experience greatly.
