Because the clearance between the teeth of the comb teeth is large and is easy to clamp the garbage, the garbage in the clearance can be cleaned in the process of retracting the tooth grooves. Alternatively, if the rows of teeth on the comb teeth are densely arranged, instead of the structure of the comb teeth grooves, it is possible to use an elongated plate-like member such as a shaving plate as the hair pushing member to scrape off the trash entangled on the comb teeth themselves when the comb teeth move below the shaving plate.

Two long holes are arranged on the end face 112 extending from the side face of the comb tooth slot 111, the hole 1121 is used for the protrusion 142 at one end of the comb tooth 14 to pass through, the hole 1122 is used for the protrusion 151 at one end of the force-bearing block 15 to pass through, further, the force-bearing block 15 further comprises an avoidance end face 153 used for reserving a placing space for the lower portion 1112 of the comb tooth slot, the bottom of the end face 112 of the comb tooth slot transversely extends out of the bottom face 113, one end of the reversing block 16 is connected to the shell through a shaft 17 so as to rotate around the shaft, a torsion spring 18 is arranged in the reversing block, one end of the torsion spring 18 supports against the bottom face 113, the other end of the torsion spring hooks one side of the protrusion 142 of the comb tooth extending hole 1121, the other side of the protrusion 142 of the comb tooth extending hole 1121 supports against the upper portion of the reversing block 16, and the lower portion of the reversing block 16 supports against the protrusion 151 of the extending hole 1122 of the force-bearing block 15.

When the comb teeth need to be cleaned, after the front end face 154 of the force-receiving block is touched to make the force-receiving block obtain a force in the direction shown by arrow a, the protrusion 151 of the force-receiving block 15 extending out of the hole 1122 applies a force to the lower portion of the reversing block 16 to make the reversing block 16 rotate counterclockwise, the lower portion of the reversing block 16 rotates inward in the direction close to the roller brush, and the upper portion of the reversing block 16 rotates outward in the direction away from the roller brush, so that the upper portion of the reversing block 16 pushes the protrusion 142 of the comb teeth 14 to move away from the roller brush, and the comb teeth 14 move to the position corresponding to the comb teeth groove 111, and the garbage wound on the comb teeth 14 cannot be cleaned off the lower comb teeth through the comb teeth groove. Just can reach the effect of clearance broach through the preceding terminal surface of touching atress piece, convenient operation is simple, and the user can operate at any time at the in-process that uses.

It should be noted that, in this embodiment, only the structure in which one side of the comb 14 interacts with one side 15 of the force-receiving block through the reversing block 16 is described, and in order to realize the translation of the comb 14, the other side of the comb 14 interacts with the other side of the force-receiving block 15 through another reversing block in the same way, and the structure is the same.

Alternatively, the force-bearing block is in the form of a bar, with the ends being thinner for passage through the aperture to interact with the diverter block. Furthermore, the bottom of the stress block can be horizontal or slope-shaped like 155 in the figure, so that the bottom is easy to rub with the ground, and rubbing the ground or other objects at the bottom can also cause the stress block to be stressed so as to push the reversing block to achieve the effect of cleaning the comb teeth, and the operation is convenient and simple.

During the normal use of the vacuum cleaner, when the force-bearing block 15 does not receive external force, the end of the comb teeth 14 extending out of the hole 1121 is hooked under the torsion of the torsion spring and kept at a fixed position, i.e. the tip of the comb teeth at this time is always inserted into the bristles 122 of the rolling brush assembly 12, so as to clean the garbage wound on the rolling brush. Alternatively, the bristles may be hard bristles arranged in one or more rows as shown in the figure, or soft bristles fully wrapping the rolling brush body, and the comb teeth need to be inserted into the bristles to a certain depth to better clean the garbage wound on the rolling brush. The front end part of the force bearing block preferably protrudes out of the shell under the condition of not bearing external force, so that the force bearing block is easy to touch the front end surface of the force bearing block through the external force to bear the force. Of course, the force bearing block can be stressed in other ways without protruding the shell.

The invention also provides a dust collector which comprises the floor brush assembly 1 in the embodiment. The vacuum cleaner may be an upright type vacuum cleaner, but is not limited thereto.
