Filter structure of vacuum cleaner

Abstract

The invention relates to a filter structure for the dust collector, comprising a filter cartridge and a filter screen with a circular top, wherein, an opening device is arranged on the end cover of the filter cartridge; the end cover of the filter cartridge is connected with the circular top of the filter screen through the opening device; the outer circular edge of the end cover of the filter cartridge is connected with the inner circular edge of the circular top of the filter screen; and the outer circular edge of the circular top of the filter screen is connected with the internal threads of central hole on the cover of a dust collecting barrel. The opening device arranged on the end cover of the filter cartridge comprises a fixed rib arranged on the end cover, a sliding block, which is provided with a spring and arranged in the groove of the fixed rib, and an insert, which is connected with the sliding block and can be inserted into the jack on the inner circular edge of the circular top of the filter screen; and an arc groove is arranged on each outer side of the fixed rib. The invention has the advantages that the filter dust is cleaned rapidly and conveniently; the dusty filter cartridge is prevented from being held by hand directly and unhygienicly; and the application effect of the dust collector and the customer prestige are improved.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a filter for a dust collecting barrel of a vacuum cleaner. Background technique [0002] The vacuum cleaner is a household appliance for indoor cleaning and hygiene, which is used to remove dust from the ground, carpets, walls, furniture 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. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an instantaneous vacuum in the vacuum cleaner, and forming a relatively high negative pressure difference with the out...

AI Technical Summary

Problems solved by technology

It can be seen that the structure of the vacuum cleaner of the above-mentioned prior art makes it very troublesome to remove dust, and the filter screen and filter core must be directly grasped by hand, which will make the user's hands full of dust, which is very unhygienic
