Description

Comb tooth structure for cleaning device, rolling brush assembly and cleaning device

Technical Field

The present invention relates to a comb structure, a rolling brush assembly, and a cleaning device, and more particularly to a comb structure, a rolling brush assembly, and a cleaning device for a cleaning device, which effectively remove hairs.

Background

The existing vacuum cleaner generally comprises a dust collector, a filter assembly and a vacuum source, and dust, debris and other garbage are collected in the dust collector through the suction of the vacuum source and the filtering action of the filter assembly. In order to improve the cleaning efficiency of the floor, a dust suction port is usually arranged at the bottom of the dust collector, and a rolling brush is arranged at the dust suction port. The rolling brush rotates to beat dust on the ground, so that the dust is lifted and sucked into the dust collector. However, since some soft hair materials such as hairs, needles and threads are often left on the floor to be cleaned, especially on the floor of some households, the soft hair materials are easily wound around the brush bristles and are transferred to the two ends of the roller brush along with the rotation of the roller brush, and finally enter the gap between the roller brush and the cleaner housing. When too much of these fluff material is in the gap between the roller brush and the cleaner housing, on the one hand, the flexibility of the roller brush shaft is affected; on the other hand, the soft fur materials enter the bearing and entangle the synchronous belt, so that the light fur materials reduce the dust collection efficiency and increase the load of a driving mechanism (such as a motor); if so, the rotating shaft of the roller brush is jammed or the synchronous belt is wound, thereby damaging the rotating shaft and the motor.

In order to effectively scrape off soft hair materials, a special hair removing structure has appeared, for example, chinese patent application CN201620876935.0 discloses a hair removing structure of a middle sweeping device, the hair removing structure of the middle sweeping device comprises a driving motor, a gear box, a middle sweeping rotating shaft and a brush, the driving motor drives the gear box to rotate, the gear box drives the middle sweeping rotating shaft to rotate, the brush is arranged on the middle sweeping rotating shaft, a plurality of comb teeth and a comb tooth fixing plate are arranged above the middle sweeping rotating shaft, the plurality of comb teeth are arranged below the comb tooth fixing plate in an equal division manner, hair on the middle sweeping rotating shaft during the comb tooth removing motion, and the normal rotation of the middle sweeping rotating shaft and the cleaning convenience are ensured.

However, the comb teeth of the chinese patent application CN201620876935.0 have sharp leading edges to form the edges of the comb teeth, and the contact area between the edges of the comb teeth and the hair is too small to cut the hair entangled in the area of the middle-sweeping rotary shaft away from the edges of the comb teeth.
