Rolling brush assembly and cleaning device

Abstract

The invention discloses a rolling brush assembly and a cleaning device. The rolling brush assembly comprises a cam shaft, a rolling brush shaft cover surface and at least two cutters. The cutter restsof the cutters are assembled in grooves corresponding to the rolling brush shaft cover surface; the cam shaft is of a shaft body structure with a guide structure, and a shaft of the cam shaft is fixedly embedded in the rolling brush shaft cover surface; the axial lengths of the guide structures on the two sides of a shaft body of the cam shaft are different. Each cutter is driven to rotate by anexternal force; the stressed body of one cutter is always pushed and extruded by the end surface with relatively large axial length of the guide structure; the stressed body drives the second blade ofthe same cutter to move relative to the first blade of the same cutter; the elastic element of the same cutter is in a force accumulation state, and when the cutter pushed away by the guide structurein an abutting mode rotates to the position where the cutter is not pushed away by the guide structure, the elastic element automatically resets the second blade of the same cutter, so that the second blade does left-right reciprocating movement relative to the first blade.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to the application field of intelligent sweeping machine products, wireless vacuum cleaners, horizontal vacuum cleaners and dust bag vacuum cleaners, and in particular to a resettable roller brush assembly and a dust collection device. Background technique [0002] Roller brushes are one of the common accessories of vacuum cleaners and smart sweepers, including a housing and a main brush housed in the housing. Because generally there are sundries such as hairs and silk threads on the ground, hairs, silk threads and other sundries are easily entangled on the roller brush shaft, which makes the roller brush shaft difficult to rotate, and then seriously affects the normal use of the whole roller brush assembly. [0003] It is difficult for the knife brush in the prior art to cut off and clean the entangled debris at the brush position of the roller brush assembly during the ...

Problems solved by technology

Because there are generally hairs, silk threads and other sundries on the ground, hair, silk threads and other sundries are easily entangled on the roller brush shaft, making it difficult to rotate the roller brush shaft, which seriously affects the normal use of the entire roller brush assembly

[0003] It is difficult for the knife brush in the prior art to cut off and clean the entangled debris at the brush position of the roller brush assembly during the operation of the roller brush, which affects the cleaning effect and user experience
