Dust cup device for dust collector

Abstract

The invention relates to a dust cup device for a dust collector, which comprises a cup body provided with a tangential total air inlet, and a separator arranged in the cup body. The dust cup device is characterized in that the separator comprises a cylindrical micropore filter which is arranged between the cup bottom and a cup cover through an end sleeve at the upper end and an end sleeve at the lower end, the transition part between the micropore filter and the end sleeve at the lower end is extended with a dust blocking cover tilting outwards, and a deposition cavity for large granule dust is formed between the dust blocking cover and the cup body. The dust cup device is further provided with a cyclone with a tangential air inlet, the lower part of the cyclone is provided with a dust blocking sheet, and the lower end of the cyclone is directly or indirectly fixed in the end sleeve at the lower end to form a deposition cavity for small granule dust; and the center of the cup cover is provided with a total air outlet and an air outlet pipe, and the air outlet pipe is matched with the air inlet on the cyclone. The dust cup device adopts various separation structures and multi-stage separation, has good separation effect, is easy to separate the large and small granule dust, is not easy for entrainment, has few components, and is easy to assemble and use.

Description

technical field [0001] The invention relates to a dust cup device of a vacuum cleaner. Background technique [0002] Due to the continuous improvement of people's living standards and the progress of science and technology, vacuum cleaners are gradually entering people's lives, families and workplaces. For this reason, scientific and technical personnel are constantly developing dust collection devices with new vacuum cleaners. [0003] For example, the Chinese patent No. 200620105888.6 "vacuum cleaner secondary cyclone separation dust cup", which includes a dust cup, an air outlet on the cup body, an air inlet tangent to the peripheral wall of the cup body and a separator located in the cup body , the separator is provided with an outer cylinder connected to the connecting bracket and the isolation cover, the outer cylinder wall is provided with a separator air inlet lower than the dust cup air inlet, and the center of the outer cylinder is provided with a coaxially placed ...

AI Technical Summary

Problems solved by technology

Its advantage is that it uses a three-leaf rotating blade to prevent the airflow from directly entraining small particles of dust, but the structure is more complicated, there are many components, installation is difficult, and the cost is high. Moreover, it is not combined with other filter separation components, so the separation effect is also limited. Moreover, the airflow channel is complicated, resulting in large airflow resistance and high energy consumption. There are many unreasonable factors, and further improvement is needed.
