Cyclone dust collector of vacuum cleaner

Abstract

The invention discloses a cyclone dust collector of a vacuum cleaner, which comprises a handle, a cyclone separator, a conical filter, a dust collecting barrel and a positioning lock connected to the dust collecting barrel, wherein an elliptic barrel body of the cyclone separator is arranged at an opening on the upper part of the dust collecting barrel; the conical filter and a rotational flow generator are arranged in the barrel body; the front end part and the rear end part of the lower barrel wall of the barrel body of the cyclone separator are provided with an air inlet port and a dust discharge port respectively; one end of the rotational flow generator is connected with the rear wall of the cyclone separator, a cavity is formed in the end of the rotational flow generator, and a plurality of through holes are formed on the end face of the other end of the rotational flow generator; the rear wall of the cyclone separator is provided with a plurality of vent holes leading to the cavity of the rotational flow generator; besides, a lateral surface, facing the rear wall of the cyclone separator, of the positioning lock is provided with a dust scraping flange. The cyclone dust collector can maintain high performance of the cyclone separator, such as air discharge for depressurization and improvement on the dust separation efficiency, and can prevent garbage from adhering or enwinding to a conical part of the conical filter.

Description

technical field [0001] The invention belongs to a vacuum cleaner, in particular to a cyclone dust collector which is provided with a ventilation hole and a dust scraping flange to reduce the exhaust pressure of the cyclone separator, improve the dust separation efficiency, and prevent garbage from adhering or entanglement. device. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the i...

Problems solved by technology

[0013] 1. The ventilation slot can effectively exhaust and decompress and improve the separation performance, but the exhaust in the dust collection bucket is easy to drive light garbage such as paper scraps, fibers, and pet hair to the ventilation slot until it is entangled and blocked on the outer bottom of the cyclone separator, making It feels unhygienic when the user dumps the dust, and it is more troublesome to clean up and clean
