Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner accessories, in particular to a roller brush end cover structure. Background Art

[0002] In order to prevent hair from entering the area where the moving parts are located on the inside of the end cover of a general vacuum cleaner roller brush, the gap between the end cover and the bearing seat is reduced, or ribs are interlaced to prevent hair from entering. However, this method cannot 100% guarantee that hair will not enter the area where the moving parts are located. During testing or actual use, some vacuum cleaners with similar structures will always have hair entangled in the moving parts of the roller brush, causing the moving parts to heat up, wear or be damaged, and the roller brush assembly will not be able to achieve the expected life requirements. It is necessary to use a roller brush end cover structure that prevents hair from entering the moving parts.

[0003] The existing roller brush end cover structure for preventing hair from entering the moving parts cannot ensure that hair will not enter the transmission part area and damage the transmission part, and cannot greatly reduce the damage rate of the vacuum cleaner roller brush transmission part, thereby increasing the service life of the vacuum cleaner roller brush part. Utility Model Content

[0004] In response to the problems in the prior art, the utility model provides a roller brush end cover structure. The utility model only needs to adjust the shape of the roller brush end cover and add a hair strip component on the traditional structure. The structure is simple and can ensure that hair will not enter the transmission component area and damage the transmission component. It can greatly reduce the damage rate of the vacuum cleaner roller brush transmission component and increase the service life of the vacuum cleaner roller brush component.

[0005] The technical solution adopted by the utility model to solve the technical problem is a roller brush end cover structure, including a roller brush body, a roller brush end cover, a roller brush shaft, a roller brush bearing, a roller brush bearing seat, and a roller brush bristle strip. The roller brush end cover and the roller brush shaft are fixed to the roller brush body by a tight fit, and the roller brush bearing is fixed to the roller brush shaft by an interference fit.

[0006] The outer side of the roller brush end cover is a cylindrical surface and there are spiral ribs on the cylindrical surface. The roller brush hair retaining strip is adhered to the inner wall of the retaining ring of the roller brush bearing seat by double-sided tape. The retaining ring on the roller brush bearing seat has an opening. The tail end of the roller brush hair retaining strip passes through the retaining ring opening and is attached to the outer side of the retaining ring of the roller brush bearing seat.

[0007] By adopting the above technical solution, the utility model only needs to adjust the shape of the roller brush end cover on the traditional structure and add a wool strip component, which has a simple structure and can ensure that hair will not enter the transmission component area and damage the transmission component. It can greatly reduce the damage rate of the vacuum cleaner roller brush transmission component and increase the service life of the vacuum cleaner roller brush component.

[0008] Specifically, the roller brush hair retaining strip is composed of a bottom plate and hair bundles fixed on the bottom plate.

[0009] Specifically, the spiral of the spiral rib extends toward the outside of the roller brush along the rotation direction of the roller brush.

[0010] By adopting the above technical solution, the hair wound around the spiral ribs of the roller brush end cover is driven by the hair bundles on the hair retaining strips of the roller brush, thereby improving the driving effect.

[0011] Specifically, the roller brush bearing seat is fixed on the outer ring of the roller brush bearing by interference fit.

[0012] Specifically, the spiral ribs on the roller brush end cover are interference fit with the hair bundles on the roller brush hair retaining strip.

[0013] By adopting the above technical solution, during the relative rotation of the hair, the spiral ribs of the roller brush end cover push the hair toward the middle of the roller brush, thereby preventing the hair from moving to the outside of the roller brush and entering the area where the moving parts inside the roller brush end cover are located.

[0014] Specifically, the roller brush hair retaining strip is a textile hair strip with nylon hair bundles.

[0015] Beneficial effects of the utility model:

[0016] (1) The roller brush end cover structure described in the utility model only needs to adjust the shape of the roller brush end cover and add a wool strip component on the traditional structure.
