Dust cup and dust collector with dust cup

Abstract

The invention discloses a dust cup and a dust collector with the dust cup. The dust cup includes a dust cup body, a channel component and a whirlwind assembly; the dust cup body is provided with an air inlet and an air outlet; the channel component is arranged in the dust cup body, and internally provided with a partitioning part to partition the interior of the channel component into an air outlet channel and an air inlet channel, the side wall, corresponding to the air outlet channel, of the channel component is provided with multiple through holes, and the side wall, corresponding to the air inlet channel, of the channel component is provided with communicated ports; the whirlwind assembly is positioned below the through holes and composed of a whirlwind canister and a spiral guiding part, the spiral guiding part is connected between the inner circumferential wall of the whirlwind canister and the outer circumferential wall of the channel component, the spiral guiding part spirallyextends in the axial direction of the channel component, and spiral channels are defined among the spiral guiding part, the whirlwind canister and the channel component, and the inlets of the spiral channels are communicated with the communicated ports. The dust cup is simple in structure, convenient to clean and capable of improving the dust and air separation efficiency of a dust removal deviceand reducing the pressure loss.

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
