When the roller body 1 rotates, the brush 22 performs normal cleaning work; when hair twines into the round brush, the strip piece 23 can prop up hair, prevents that hair from winding on the rolling body 1 excessively tightly, convenient clearance.

The bristles 22 and the strips 23 of the bristle strip combination are connected into a whole through the middle piece, and the integrally connected bristle strip combination is arranged on the roller body 1 in an inserting mode, so that the installation and the disassembly are convenient.

In the embodiment, the intermediate member is a retainer 21, and the retainer 21 is detachably connected with the roller body 1, so that the assembly and disassembly are convenient; the holder 21 is provided with a positioning groove, one end of each of the brush bristles 22 and the strip-shaped elements 23 is inserted into the positioning groove, and the other end of each of the brush bristles and the strip-shaped elements extends in the direction away from the roller body 1, so that the mounting and dismounting are convenient. The bristles 22 and the bar 23 can be replaced individually or simultaneously during replacement.

Here, the number of the brush bristles 22 is not limited, and a plurality of brush bristles 22 may be provided, and the plurality of brush bristles 22 are spirally distributed or V-shaped distributed along the circumference of the roller 1, which is beneficial to increasing the area of the region between adjacent brush bristles 22 and improving the suction force and dust removal effect of the dust collector.

The holder 21 supports the bristles 22 and the strip 23 and facilitates the connection to the roller 1 and also the replacement of the bristles 22 and the strip 23. Specifically, the roller body 1 is provided with an installation groove at a position corresponding to the holder 21, and the holder 21 is inserted into the installation groove. In order to make the connection more stable, locking elements, such as screws, may be arranged between the holder 21 and the roller body 1.

One end of the brush hair 22 is provided with a first limit part 221, and a plurality of brush hairs are fixed on the first limit part 221, so that the brush hairs are prevented from loosening and are conveniently connected with the holder 21 as a whole; one end of the bar-shaped member 23 is provided with a second limiting portion 231, and the first limiting portion 221 and the second limiting portion 231 are inserted into the positioning groove at the same time, so that the positioning groove can clamp the first limiting portion 221 and the second limiting portion 231 to limit the bristles 22 and the bar-shaped member 23.

In this embodiment, the holder 21 includes a bottom plate 211, two side plates 212 and a position-limiting plate 213, the two side plates 212 are spaced apart from each other on the bottom plate 211, the position-limiting plate 213 is disposed at an end of the side plate 212 far from the bottom plate 211, and the bottom plate 211, the side plates 212 and the position-limiting plate 213 enclose to form a positioning slot.

The constant head tank is T type groove, and the both sides of constant head tank can be spacing first spacing portion 221 and the spacing portion 231 of second respectively. Specifically, one side of the first position-limiting portion 221 is inserted into the positioning groove, and the other side of the first position-limiting portion is abutted to the second position-limiting portion 231; similarly, one side of the second position-limiting portion 231 is inserted into the positioning groove, and the other side thereof is abutted against the first position-limiting portion 221.

Along the length direction of the positioning groove, the extension length of the brush bristles 22 is the same as that of the strip 23, namely, the strip 23 and the brush bristles 22 are consistent in length, so that the extending direction of the brush bristles 22 can comprehensively play a role in preventing entanglement.

In the radial direction of the roller body 1, the bristles 22 extend longer in a direction away from the roller body 1 than the strip 23. The bristles 22 which are higher can effectively go deep into the carpet, and the ash in the deep part of the carpet is beaten out, so that the dust removal efficiency is improved.

Optionally, one side of the brush 22 is fixed on the holder 21, and the other side is in the shape of uneven waves, so that the brush 22 can adapt to various cleaning environments, the convex part can extend into the carpet, and the concave part can clean dust on the plane.

The embodiment of the utility model provides a still provide a dust catcher, adopt above-mentioned anti-twining hair round brush to prevent that the hair from winding on the rolling body 1 excessively tightly when the dust absorption, be convenient for clear up, reduce the fault rate of dust catcher effectively.

The dust collector comprises a fan cover, the roller body 1 is rotatably arranged in the fan cover, at least one row of comb teeth 3 are arranged in the fan cover, and the comb teeth 3 are fixed in the fan cover. During the rotation of the roller 1, the comb teeth 3 can pass through the bristles 22 and contact the strip 23. The number and position of the comb teeth 3 are set according to practical circumstances and are not limited herein.

When the roller body 1 rotates, the brush hair 22 can contact with the comb teeth 3, the comb teeth 3 can penetrate through the brush hair 22, dust on the brush hair 22 scatters, the brush hair 3 contacts with the strip-shaped parts 23 along with the rotation of the roller body 1, the strip-shaped parts 23 vibrate to a certain degree, and then hair wound on the brush hair 22 moves back and forth on the strip-shaped parts 23, and the comb teeth 3 are matched with the strip-shaped parts 23, so that the hair is favorably wound and loosened, and the cleaning is convenient.

In this embodiment, the strip 23 is a leather strip. Of course, the strip 23 may also be a canvas strip, a plastic strip or a rubber strip, without limitation, as long as the hair can be supported.

When the strip 23 has elasticity, the comb teeth 3 can penetrate through the bristles 22 and push the strip 23 to generate elastic deformation along the circumferential direction of the roller body 1, and the strip 23 passes through the comb teeth 3 after the elastic deformation along with the further rotation of the roller body 1, and the elastic deformation is recovered. The strip-shaped member 23 is intermittently deformed, so that the strip-shaped member 23 generates larger vibration, and further, the hair wound on the brush bristles 22 moves back and forth on the strip-shaped member 23, thereby further facilitating the hair to be wound and loosened and facilitating the cleaning.

The above embodiments have been described only the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and is not departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
