Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1-5 Shown is a dust cup device for a vacuum cleaner, which includes a cup body 1, a cup cover 2 and other components, wherein the upper part of the cup body 1 has a tangential general air inlet 4 for easy air intake, and the cup body is divided into a main body 5 and a lower end. The cup bottom 3 is fixed on the lower end of the cup body 1 through a detachable connection such as threaded connection or clip connection, and there is also a cylindrical microporous filter 6 with a filtering effect. The filter 6 extends upwards with a diameter-enlarged, hollow cylindrical sleeve as the upper end sleeve 7, and extends downward with a diameter-reduced, hollow cylindrical sleeve as the lower end sleeve 8, so that It is directly arranged between the cup cover 2 and the cup bottom 3 of the dust cup. In order to limit the position...

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 ...
