Compared with the prior art, the invention can automatically remove foreign matter such as hair entangled on the roller brush during the brush cleaning operation, and the cleaning process is simpler and more convenient, and the cleaning efficiency can be greatly improved.
The present invention will be further described below in conjunction with the accompanying drawings and embodiments:
The design scheme of the present invention to achieve the above objectives is:
Referring to
The sliding of the hair removal knife 41 and the sliding block 4 can be driven by the groove wall of the reciprocating spiral groove 12 when the roller brush 1 is rotated, or by other driving structures, because of the reciprocating spiral groove 12 pushing the hair removal knife 41 and the sliding block 4 to slide, there is a higher speed contact friction between the hair removal knife 41 and the groove wall of the reciprocating spiral groove 12. In this embodiment, in particular, in order to reduce wear and increase the service life, a second driving structure for driving the sliding block 4 to reciprocate along the sliding rail 3 is further included, and the second driving structure includes a reciprocating screw rod 5 that cooperates with the sliding block 4, and the reciprocating screw rod 5 is parallel to the slide rail 3 to drive the sliding block 4 through the reciprocating screw rod 5 to drive the hair removal knife 41 to move. And in order to make the movement of the hair removal knife 41 consistent with the rotation of the roller brush 1 and always in the reciprocating spiral groove 12, in the embodiment, the second driving structure includes a secondary transmission mechanism 6, and the roller brush 1 drives the reciprocating screw rod 5 to rotate simultaneously by the secondary transmission mechanism 6. In particular, the secondary transmission mechanism 6 includes a secondary active synchronous wheel disposed on the roller brush 1, a secondary driven synchronous wheel disposed on the reciprocating screw rod 5, and the secondary synchronous belt connecting of the secondary active synchronous wheel and the secondary driven synchronous wheel. Of course, according to the actual situation, the secondary transmission mechanism 6 can also adopt other types of transmission mechanisms, such as a gear transmission mechanism, in addition to the synchronous wheel transmission mechanism, as long as the transmission ratio is relatively constant during the transmission process, for example, a method of providing a secondary driving gear on the roller brush 1 and a secondary driven gear meshing with the secondary driving gear on the reciprocating screw rod 5 may be adopted.
In the present embodiment, preferably, the surface of the roller brush 1 is provided with a plurality of spiral protrusions 13 between which the reciprocating spiral grooves 12 are formed. Moreover, preferably, the spiral protrusion 13 is made of soft rubber, because the soft rubber has elasticity, and can avoid the damage caused by the collision with the ground during the cleaning operation of the roller brush 1, which is beneficial to improve the service life. Of course, according to the actual situation, in addition to the soft rubber, the spiral protrusion 13 can also be formed by integrally forming with the roller brush 1; and the reciprocating spiral groove 12 can also be formed directly on the body of the roller brush 1 by slotting.
In this embodiment, specifically, the hair removal knife 41 is provided with a hook-shaped blade 411, and one end of the hook-shaped blade 411 away from the sliding block 4 is disposed in a hook shape structure, and the blade edge is disposed on the inner side of the hook shape structure in order to loosen and cut the foreign matter such as hair wound on the roller brush 1; and the hook-shaped blade 411 is provided with two pieces, and the backs of the two hook-shaped blades 411 are connected in a V shape in order to improve the overall rigidity of the hair removal knife 41, and the problem that the hair removal knife 41 is bent or even broken due to excessive resistance of the foreign matter such as hair on the roller brush 1 is avoided. Specifically, when the hair removal knife 41 is located in the first spiral groove, one of the hook-shaped blades 411 is parallel to the tangent line of the first spiral groove, when the hair removal knife 41 is located in the second spiral groove, the other of the hook-shaped blades 411 is parallel to the tangent line of the second spiral groove; so that the hair removal knife 41 has one hook-shaped blade 411 in the process of going back and forth, cutting the hair along the tangential direction of the reciprocating spiral groove 12.
In the present embodiment, in order to prevent the hair removal knife 41 from damaging the tufting bundle 11 during the reciprocating motion, in particular, the tufting bundle 11 is evenly distributed on the roller brush 1 and keeps away from the position of the reciprocating spiral groove 12.
The above is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and as long as it achieves the technical effects of the present invention by any identical or similar means, it should fall within the protection scope of the present invention.
