Description

Floor cleaning brush and dust collector with same

Technical Field

The invention relates to a dust suction device, in particular to a floor cleaning brush for a dust collector. The invention also relates to a dust collector with the floor cleaning brush.

Background

The dust collector is a household appliance for removing dust, and mainly utilizes a motor to generate negative pressure in the dust collector, so that dust and sundries near an air suction port can be sucked into the dust collector, and the effect of removing dust is realized. In order to thoroughly remove the dust and the sundries, a rolling brush can be arranged outside the air suction port, and the dust and the sundries are collected through the rotation of the rolling brush. In use, the ground is often wrapped around the surface of the rolling brush by human hair or other long-strip or large sundries along with the rotation of the rolling brush. Meanwhile, when hair or long foreign matters are sucked, if the hair or long foreign matters are just positioned on the two end faces of the rolling brush, the two end faces are the positions for fixing the rolling brush to rotate, gaps generally exist, and at this time, if the hair is wound into the gaps, the rotation of the rolling brush is influenced, and the hair or long foreign matters are very difficult to clean and even damage the floor brush.

As an improvement, a plurality of dust-collecting brush heads with square winding bristles are disclosed in the prior art, and a chinese patent application with application number 201810347144.2 discloses an electric floor brush with an anti-bristle winding function (application publication number CN 108451441 a), the application comprises a floor brush body, a rolling brush and a motor hole transmission mechanism, the transmission mechanism comprises a transmission wheel, fan blades are arranged on the transmission wheel, when the transmission wheel rotates, the fan blades rotate along with the transmission wheel to generate an air flow at the bearing, and the air flow blows hairs near the bearing to a dust-collecting inlet of the floor brush, so that the hairs are prevented from lingering at the rolling brush and the bearing for a long time.

Can also refer to chinese utility model patent 'preventing that the round brush from advancing hair kinking structure' (grant publication No. CN 209595655U) with patent number ZL201822149346.4, this patent includes the roller bearing, locates roller bearing brush hair all around, still includes a pair of pivot and locates a pair of fender hair subassembly at roller bearing both ends, keeps off the hair subassembly and includes interior fender lid and outer fender lid, and interior fender lid and outer fender lid mutually cover and close and rotate the connection, and interior fender lid and roller bearing fixed connection, outer fender lid is passed in proper order in the pivot, and interior fender lid back and roller bearing fixed connection. When the floor is cleaned, the rotating shaft penetrates through the hair blocking assembly, and hair or fur is blocked outside the inner blocking cover and the outer blocking cover, so that the hair or fur can be prevented from being drawn into the rotating shaft; simple structure and convenient cleaning.

Refer to chinese utility model patent No. ZL201920862826.7, head and dust collector of dust catcher and dust catcher (No. CN 210354562U) that can effectively prevent the round brush from winding hair, this patent includes round brush and the support that is used for installing the round brush, and the both ends of round brush are installed respectively on the support, extend towards the round brush at least on the support and form a turn-ups of tube-shape, and the turn-ups is at least partially with the end interference fit of round brush.
