Water filtering and dust removing device of dust collector

Abstract

The invention discloses a water-filtering dedusting device of a dust catcher, which is mainly featured in that the end of an air inlet pipe in a dust cup is provided with a diffusion element with a downward opening. When the dust catcher catches dust, dusty gas with a certain speed passes through the air inlet pipe and then reaches the diffusion element; under the diffusion effect of the diffusion element, the speed of the dusty air is slowed down, the contact surface with water is enlarged and the contact is more complete, so dust in the dusty air can be filtered by water more completely and the filter quality of the water-filtering dedusting device of the dust catcher can be improved. Meanwhile, the invention also discloses a water-filtering dust catcher. Three baffles arranged in a water-gas separation chamber of the water-filtering dust catcher form a twisted wind channel which can obstruct moist air and change the flowing direction of the moist air after water filtering, and fine grains in the air can be further attached and filtered so as to greatly improve the filtering quality and dedusting effect of the water-filtering dust catcher.

Description

technical field [0001] The invention relates to a filter type dust removal device for a vacuum cleaner, in particular to a water filter dust removal device for a vacuum cleaner. Background technique [0002] The principle of filter dust removal is to collect dust through filter materials such as filter bags or filter screens, so as to achieve the effect of dust removal. Its characteristics are: simple structure, but the filtering accuracy is not very high. Because high filtration accuracy will bring about the increase in the cost of filter materials and the poor circulation of wind, resulting in losses. [0003] The water filtration system is a kind of filter dust removal system, which is derived from the filter dust collection system. It uses water as the filter material to capture dust. As an emerging dust filtration technology, water circulation filtration technology has been more and more used in the field of vacuum cleaners, especially in upright vacuum cleaners, wate...

AI Technical Summary

Problems solved by technology

However, the dust removal efficiency of the water filtration and dust removal device of this type of vacuum cleaner is still not high. The reason is that the air duct structure in the water-air separation room is single, and there is often a lack of tortuous air guide paths. Some small dust particles are still entrained in the airflow after passing the water. However, it cannot be well blocked or secondary filtered. Under the suction of the motor, these small dust particles are easily discharged into the atmosphere from the air outlet of the body again, affecting the final filtration quality.
