Roller brush fast dismounting and mounting device and cleaning instrument thereof

Abstract

The invention discloses a roller brush fast dismounting and mounting device and a cleaning instrument thereof. The roller brush fast dismounting and mounting device comprises an ejection device and a position limiting device, wherein the ejection device exerts axial ejection elastic force on a roller brush; the position limiting device converts the elastic force into elastic potential energy and limits the axial displacement of the roller brush; the ejection device comprises an ejector pin and a pressure spring; the ejector pin is arranged inside an axial blind hole formed in one end of the roller brush; the ejector pin is provided with a flange; the pressure spring exerts axial elastic force on the ejector pin through abutting the flange; an ejector pin press plate for limiting the ejector pin to be disengaged from the blind hole is arranged in the opening position of the blind hole; one end of the roller brush is connected with a bearing seat; the roller brush has the rotating degree of freedom for rotating around the self axial line relative to the bearing seat; the position limiting device is provided with a release key with a projected part and a bearing seat with a position clamping groove; the projected part is matched with the position clamping groove. By using the device, the dismounting or the mounting of the roller brush can be realized only through one step; the cleaning of the roller brush is convenient; the roller brush mounting and dismounting efficiency is further improved; the operation environment is improved.

Description

technical field [0001] The invention relates to a cleaning appliance, in particular to a quick disassembly and assembly device for a roller brush and the cleaning appliance. Background technique [0002] In daily use, the roller brush of the sweeper is easy to get entangled with fine objects such as hair and wool. If it is not cleaned regularly, the motor may receive a large torque due to the high load and cause the body to heat up. If this continues over time, it may increase the load on the battery and affect its life. If the situation is serious, it will directly burn the motor. The roller brushes need to be cleaned regularly. You can open the roller brush chamber first, check the bottom brush and rubber brush, remove the two roller brushes, remove the brush covers on the left and right sides of the brush and the brush shaft on the right, check and Cleans hair that is wrapped around the roller brush shaft. After cleaning the roller brush, put the roller brush back into ...
