Cyclone Separators & Vacuum Cleaners

Abstract

The invention provides a cyclone separator and a vacuum dust collector. The cyclone separator comprises a dust cup which is provided with a cyclone separating chamber therein, an air inlet and an airoutlet, a filter shield and an ash cleaning device, wherein a bottom cover is arranged at the bottom of the dust cup, and the bottom cover can move between a position of closing the bottom of the dustcup and a position of opening the bottom of the dust cup; the filter shield is arranged in the cyclone separating chamber; the filter shield comprises a filter surface which is provided with a plurality of meshes; the filter surface is configured to permit an airflow to move from the air inlet to the air outlet; the ash cleaning device comprises an ash cleaning piece which is arranged in the cyclone separating chamber, and the ash cleaning piece sleeves the periphery of the filter shield; and the ash cleaning piece, under self-gravity and / or an action of resetting force of a spring, can slideup and down along the filter surface and can get into friction with the filter surface in a sliding process when the bottom cover is released from the closing position to the opening position. According to the cyclone separator and the vacuum dust collector provided by the scheme, dust on the surface of the filter shield can be cleaned simply and conveniently when the bottom cover is opened.

Description

technical field [0001] The invention belongs to the field of vacuum cleaning equipment, and in particular relates to a cyclone separator and a vacuum cleaner. Background technique [0002] At present, the cyclone separator uses the principle of high-speed centrifugation to separate the dust from the air flow to achieve the purpose of gas-solid separation. The cyclone separation assembly is a relatively common part in most cyclone vacuum cleaners. The cyclone separation assembly generally includes a dust cup with a cyclone separation chamber inside, an inlet for carrying the fluid with solid matter to the cyclone separation chamber, and After the solid matter is separated, the fluid is discharged from the cyclone separation chamber. A filter cover is arranged inside the cyclone separation chamber. The filter cover has a mesh portion, and several mesh holes are arranged on the mesh portion. The outlets are connected in turn, and the airflow separated by the cyclone separation...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned technical deficiencies, the first object of the present invention is to provide a cyclone separator to solve the technical problems that the existing cyclone separator is troublesome to remove the dust on the surface of the filter cover and the dust removal effect is not ideal;

[0006] The second purpose of the present invention is to provide a vacuum cleaner to solve the technical problems that the existing vacuum cleaner uses the existing cyclone separator to remove the dust on the surface of the filter cover, which is troublesome and has an unsatisfactory dust removal effect
