Dust cup device of dust collector and dust collector

Abstract

The invention discloses a dust cup device of a dust collector. The dust cup device is provided with an air inlet, a primary dust collecting chamber, a secondary dust collecting chamber, a primary cyclone separator, a secondary cyclone separator and an air outlet. The secondary dust collecting chamber surrounds the primary dust collecting chamber. The primary cyclone separator comprises a primary cyclone chamber and a primary cyclone passage. The primary cyclone passage comprises a surrounding wall and a partition plate, and the partition plate is extended from the bottom of the cyclone chamber to the crude dust receiving bottom of the primary dust collecting chamber, is spiral and forms the primary cyclone passage together with the surrounding wall. The secondary cyclone separator comprises a cyclone, a mesh filter and a flow deflector. The flow deflector is spirally extended from the bottom of the cyclone to the top of the cyclone, is positioned between the inner wall of the cyclone and the outer wall of the mesh filter and forms a spiral secondary cyclone passage together with the inner wall of the cyclone and the outer wall of the mesh filter. Because the dust cup device is provided with the primary spiral cyclone passage and the secondary spiral cyclone passage, the speed of the dust can be fully reduced, and the separation effect is good.

Description

[0001] technical field [0002] The present invention relates to a cleaning appliance, in particular to a vacuum cleaner, in particular to a dust cup device of the vacuum cleaner. Background technique [0003] Chinese patent application No. 200920184866.7 discloses a vacuum cleaner, which includes a primary cyclone separator, a plurality of secondary cyclone separators arranged side by side, the primary cyclone separator is located in the secondary cyclone separator Upstream of the primary cyclone separator, the primary cyclone separator includes a primary cyclone bucket, a primary dust collection chamber located below the primary cyclone bucket, and a primary deflector column arranged inside the primary cyclone bucket. The barrel wall of the primary cyclone barrel has a primary air inlet and a primary ash outlet in a direction tangent to the inner wall of the barrel, and the primary ash outlet is located below the primary guide column and along the It is set along the tang...
