Technical Field

the invention relates to the field of rotary cleaning, in particular to a rolling brush winding cutting device and a dust suction device applying the same.

Background

a vacuum cleaner is a common cleaning device, which generally includes a dust collector, a filter assembly and a vacuum source, and the dust collector collects dust or debris and other garbage by suction of the vacuum source and filtration of the filter assembly.

At present, dust collectors or sweeping robots using floor brushes all use rolling brushes, and the rolling brushes commonly comprise bristle planting rolling brushes and flocking rolling brushes, and the bristle planting rolling brushes are divided into density parts. The rolling brush is easy to wind filaments such as hair and the like in the cleaning process, and the winding not only can influence the dust collection effect, but also can increase the loss of a motor of the rolling brush and reduce the service life of the dust collector if not cleaned in time.

Disclosure of Invention

In view of the defects in the prior art, an object of the present invention is to provide a device for cutting entanglement on a rolling brush, which can automatically cut entanglement on the rolling brush without requiring a user to manually clean the entanglement, and can improve the dust collection effect and prolong the service life of a dust collector.

In order to achieve the purpose, the invention provides the following technical scheme:

A rolling brush entanglement cutting device comprises comb teeth, slices and a driving device, wherein the comb teeth and the slices are in contact fit with each other, the driving device is used for controlling the slices to reciprocate relative to the comb teeth, and a limiting and pressing assembly is arranged between the comb teeth and the slices; the equipartition is provided with decides the tooth on the broach, on the section equipartition be provided with decide tooth complex move the tooth, decide tooth prong protrusion in move tooth prong.

Further, drive arrangement includes gear motor, the last eccentric wheel that is provided with of gear motor, seted up on the section with eccentric wheel complex drive hole.

further, the length of the slice is smaller than the length of the comb teeth.

Furthermore, the limiting and pressing assembly comprises a limiting column penetrating through the comb teeth and the slices, one end of the limiting column is provided with a fixing plate, the other end of the limiting column is provided with a limiting plate, and a spring with two ends respectively contacted with the slices and the limiting plate is sleeved on the limiting column; the comb teeth are provided with positioning holes matched with the limiting columns, and the section is provided with positioning grooves matched with the limiting columns.

furthermore, the limiting plate is detachably connected with the limiting column.

The invention also aims to provide a dust collector applying the rolling brush winding cutting device, which comprises a rolling brush and a rolling brush shell, wherein the limiting and pressing assembly is fixedly connected with the rolling brush shell; and the rolling brush shell is provided with an inlet knife edge for the fixed teeth and the movable teeth to extend into.

Furthermore, the end face of the fixed tooth opposite to the rolling brush is tangent to the outer circumferential face of the rolling brush.

In conclusion, the invention has the following beneficial effects:

1. The winding object cutting device of the rolling brush is adopted, so that the winding object on the rolling brush can be automatically combed and collected, the winding object is cut up, the cut winding object can be absorbed into a dust collector of a dust collector, a user does not need to clean the winding object by hands, the dust collection effect can be improved, and the service life of the dust collector is prolonged;

2. the structure is simple, the production cost is low, the economic applicability is strong, and the maintenance is convenient;

3. The fixed teeth are matched with the movable teeth, so that the flocking rolling brush can be suitable for a sparse or fine flocking rolling brush and can be suitable for a flocking rolling brush.
