Specifically, the suction hole 114 is provided opposite to the middle position of the first mounting groove 112, and uniform suction of foreign substances can be achieved.

As shown in fig. 6, in some embodiments, optionally, the foreign matter removal portion 116 forms a comb 120 toward a side of the sleeve 122.

In this embodiment, the foreign matter removal portion 116 forms the comb teeth 120 toward the side of the sleeve 122, and further foreign matters on the rolling brush 130 are more easily scraped off by the comb teeth 120 and the foreign matter removal portion 116, further reducing the possibility of foreign matters being entangled on the rolling brush 130.

Specifically, the number of the comb teeth 120 is plural, and the comb teeth 120 are disposed opposite to the bristles and the gaps between the bristles, thereby facilitating the hooking of foreign matter out of the bristle part 134. The comb teeth 120 may have a needle-like structure, a plate-like structure, or the like.

The comb teeth 120 include a plurality of teeth arranged side by side, and the teeth are arranged at intervals, so that a gap between the bristles can be inserted, and a certain gap is formed between the teeth of the comb teeth 120 and the sleeve 122, and the range of the gap is greater than 0 and less than or equal to 2mm. The tooth portion may be directly disposed on the housing 110, or the foreign matter removal portion 116 may further include a connection portion, one end of which is connected to the housing 110 and the other end of which is connected to the tooth portion.

Wherein the blade 126 may be made of metal, for example: iron material, iron alloy material, copper alloy material, plastic material, ceramic material, or the like.

As shown in fig. 2, 3, and 4, in some embodiments, the foreign matter removal portion 116 and the housing 110 are optionally in a unitary structure.

In this embodiment, the foreign matter removing portion 116 and the housing 110 are integrally formed, so that the mounting step of the foreign matter removing portion 116 and the housing 110 is omitted, and the production efficiency is improved.

Specifically, the foreign matter removal portion 116 and the housing 110 may be of plastic material, and the housing 110 may be of transparent material, with the foreign matter removal portion 116 and the housing 110 being injection molded.

As shown in fig. 2, 3 and 9, in some embodiments, optionally, the roll brush 130 further includes a shutter 136 provided on the brush body 132, the shutter 136 protruding from the peripheral side wall of the brush body 132, and the shutter 136 being located at one side of the bristle part 134 in the rotation direction of the brush body 132, the bristle part 134 and the shutter 136 being extendable and retractable into the sleeve 122 through the through-hole 124 in the case that the sleeve 122 and the roll brush 130 are rotated.

In this embodiment, the roller brush 130 includes a brush body 132, a bristle part 134, and a shutter 136, the bristle part 134 and the shutter 136 being disposed at a peripheral side of the brush body 132 and protruding from the brush body 132, wherein the shutter 136 is disposed at one side of the bristle part 134 in a rotation direction of the brush body 132, the shutter 136 and the bristle part 134 being disposed opposite to the same through hole 124, and the bristle part 134 and the shutter 136 being extendable and retractable into the sleeve 122 through the same through hole 124.

As the roller brush 130 and sleeve 122 rotate, the bristle part 134 and the shutter 136 may begin to extend from the same through hole 124 out of the sleeve 122 in a first position and continue to increase the length of the bristle part 134 and the shutter 136 extending out of the sleeve 122, after the length of the bristle part 134 and the shutter 136 extending out of the sleeve 122 reaches a maximum, begin to retract into the sleeve 122 and continue to decrease the length of the bristle part 134 and the shutter 136 extending out of the sleeve 122, and finally in a second position the bristle part 134 and the shutter 136 may retract into the sleeve 122.

At the opening of the first mounting groove 112, the bristle part 134 and the shielding member 136 extend out of the sleeve 122, so that the surface to be cleaned can be cleaned, and as the shielding member 136 is arranged on one side of the bristle part 134, the depth of foreign matters on the bristle part 134 entering into the bristle part 134 can be reduced, the bristle part 134 and the shielding member 136 retract into the sleeve 122 at the inner side of the first mounting groove 112, so that the edge of the through hole 124 can scrape the foreign matters on the bristle part 134, and then the foreign matters are scraped by combining with the foreign matters removing part 116, so that the cleaning effect on the rolling brush 130 is further improved, and the possibility of winding the foreign matters on the rolling brush 130 is reduced.

As described above, the shutter 136 and the bristle part 134 move synchronously, and thus when the foreign matter is to be inserted into the bristle part 134, the shutter 136 can block the foreign matter to only a small portion of the bristle part 134, thereby reducing the binding force of the foreign matter and the bristle part 134, and further, when the foreign matter removing part 116 catches the foreign matter, the foreign matter can be smoothly separated from the bristle part 134.

In addition, the bristle part 134 is positioned at the front side of the shutter 136 along the rotation direction of the roller brush 130, thereby facilitating the cleaning of foreign matter by the bristle part 134.

In this embodiment, the shielding member 136 includes a limiting portion 138 and a protruding portion 140, the limiting portion 138 is embedded in the brush body 132, the protruding portion 140 is disposed on the limiting portion 138 and protrudes from the brush body 132, and, along the rotation direction of the brush body 132, the protruding portion 140 is located at one side of the brush body 134, shielding the foreign matter by the protruding portion 140, reducing the possibility of the foreign matter being wound around the roller brush 130, and increasing the connection strength of the shielding member 136 and the brush body 132 by the limiting portion 138, reducing the possibility of the brush body 132 being detached.

Wherein, the width of the protruding portion 140 is smaller than the width of the limiting portion 138.

In some embodiments, the shield 136 is optionally a resilient shield, and the shield 136 may be bent in a direction away from the brush body 132.

In this embodiment, the shielding member 136 is an elastic shielding member, and the shielding member 136 may be bent in the rotation direction of the brush body 132, so that the shielding member 136 and the brush body 134 may be bent to secure the cleaning effect when the brush body 134 cleans the surface to be cleaned.

Specifically, the shielding member 136 may be made of rubber, silica gel, or leather.

As shown in fig. 3, taking the rotation of the brush body 132 along the W direction as an example, the shielding member 136 may be bent along the direction deviating from the W, and then when the floor brush 100 of the dust collector works, the brush body 132 rotates, the shielding member 136 and the bristle portion 132 contact with the surface to be cleaned, so as to bend toward the direction deviating from the W, and the contact area between the bristle portion 132 and the surface to be cleaned is increased, thereby improving the cleaning effect of the dust collector.
