Dust cup and dust collector provided with dust cup

Abstract

The invention discloses a dust cup and a dust collector provided with the dust cup. The dust cup comprises a dust cup main body, a passage piece and a spiral passage piece, wherein an air inlet is formed in the bottom of the dust cup main body and an air outlet is formed in the top of the dust cup main body; the passage piece is arranged in the dust cup main body; the lower end of the passage piece is connected to the air inlet, and the upper end of the passage piece is connected to the air outlet; a dividing piece is arranged in the passage piece, so that the interior of the passage piece isdivided into an air outlet passage and an air inlet passage which is arranged under the air outlet passage; a plurality of through holes are formed in the sidewall, corresponding to the air outlet passage, of the passage piece, and a communicating port is formed in the sidewall, corresponding to the air inlet passage, of the passage piece; one end of the spiral passage piece is connected to the communicating port and the other end of the spiral passage piece extends upwards in a spiral form along the axial direction of the passage piece until to the sidewall of the dust cup main body; and theother end of the spiral passage piece communicates with the interior of the dust cup main body. The dust cup provided by the invention is simple in structure and convenient for cleaning; and the dust-gas separating efficiency of a dust collection device can be improved, and pressure loss can be reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a dust cup and a vacuum cleaner with the same. Background technique [0002] In the field of dust and gas separation technology, the pressure loss of the multi-cone dust and gas separation structure is relatively large, the structure is relatively complicated, it is inconvenient to clean the dust inside, and it will occupy a large space inside the dust cup. In recent years, some single-cone dust-gas separation structures can achieve the same dust-gas separation efficiency as multi-cone dust-gas separation structures, while the pressure loss is smaller. However, in the related art, the single-cone dust-gas separation structure still has the following problems: (1) The dust-gas separation structure is unreasonable, resulting in low dust-gas separation efficiency; (2) The pressure loss of the dust-gas separation structure is relatively large; (3) With the increase of d...

Problems solved by technology

However, in the related art, the single-cone dust-gas separation structure still has the following problems: (1) The dust-gas separation structure is unreasonable, resulting in low dust-gas separation efficiency; (2) The pressure loss of the dust-gas separation structure is relatively large; (3) With the increase of dust suction, the pressure loss increases, resulting in a rapid drop in suction power, and the unseparated dust particles will accumulate on the filter cotton, resulting in filter cotton clogging, increased pressure loss, and inconvenient cleaning
