Filtering box of dust collector

Abstract

The invention relates to a filtering box of a dust collector, comprising a box body, an upper cover provided with an air inlet and a filtering sponge arranged in the box body and further comprising a circular baffle, wherein the circular baffle is arranged above the filtering sponge in the box body below the air inlet; one side of the circular baffle, facing to the air inlet, is a convex surface; and the circular baffle is connected on the air inlet by a plurality of hanging springs. In the filtering box of the dust collector, the circular baffle is arranged at the part blocked by dust, namely below the air inlet so as to guide the gas flowing from the air inlet, the dust particles in the gas are dispersed on the area of the whole sponge instead of gathering at the circular area of the filtering sponge below the air inlet to cause blocking. Therefore, the dust does not block the air inlet of the filtering box, so the collecting capability of the dust collector is guaranteed.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, and in particular relates to a circular baffle under the air inlet to guide the gas, so that the dust is not concentrated at the filter sponge with a circular area under the air inlet, and the air inlet will not be blocked, ensuring the vacuum cleaner Suction vacuum cleaner filter box. 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 in the body through the telescopic tube and flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor driv...

AI Technical Summary

Problems solved by technology

[0005] After the existing vacuum cleaner (model Nile) was put into the market, the survey of customers revealed that the dust was often blocked in the filter box, causing the suction power of the machine to drop rapidly. The dust was completely blocked in the circular area corresponding to the air inlet of the filter box. If the sponge is blocked, the air volume will be close to zero. At this time, the vacuum cleaner will completely lose the function of dust collection, which will bring great inconvenience to customers and arouse great opinions from customers.
