Problems solved by technology

[0005] Since the first-level dust separator and the second-level dust separator are in the same cavity, it is inevitable that a small amount of unseparated air will directly enter the air inlet of the second-level dust separator from the first-level dust separator with the airflow, resulting in the second-level separation. The workload increases, and if the filter is placed directly above the dust collection chamber, it is easy to cause the raised dust to enter from the mesh of the filter and leave the dust cup, which will affect the effect of cyclone separation

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] see figure 1 , a cyclone-separated dust cup for a vacuum cleaner, comprising a cylindrical cup body 1 and a dust cup cover 2, wherein the upper end of the side wall of the cup body 1 is provided with a tangential first-stage air inlet 11, and the dust cup cover 2 is provided with Air outlet 21.

[0026] see figure 2 and image 3 The bottom wall of the cup body 1 is provided with two circular convex ribs 12, the dust collection chamber gasket 3 is inserted between the two convex ribs 12, and the distance between the two convex ribs 12 is the same as that of the dust collection chamber gasket 3 to match the width. The lower wall 4 of the cyclone separator is fixed on the outer part of the gasket 3 of the dust collection chamber. The lower wall 4 of the cyclone separator has two parts, the upper part is in the shape of an inverted fru...

Abstract

The invention discloses a cyclone separation dust cup of a dust collector, which adopts a rationally-configured three-stage cyclone separation capable of improving the cyclone separation efficiency of the dust cup and enabling the dust to be remained in a dust collecting chamber of the dust cup instead of being conveyed to the fan or being polluted twice. Each stage of cyclone separator is provided with a cone apron edge or a cone surface, with which the air flow is accelerated and then decelerated while entering the oversized space at the lower part; then the dust is deposited instead of being taken away. Compared with cyclone separator having straight barrel, the utility model has better cyclone separation effect.

Description

technical field [0001] The invention relates to a dust cup of a vacuum cleaner, in particular to a cyclone-separated dust cup. Background technique [0002] The dust cup used for filtering is the main part of the vacuum cleaner. In order to better separate impurities such as dust from the air, most existing vacuum cleaners use a cyclone dust cup for secondary separation. The air containing impurities enters the first-stage separator along the tangential direction, and makes a rotary motion from top to bottom. During the rotary process, large particles and heavier impurities collide with the first stage due to their greater density than air and greater centrifugal force. The inner wall of the separator loses its inertia and falls into the dust collecting chamber below to be separated from the air. The finer impurities and air enter the second-stage separator, and the fine dust collides with the inner wall of the second-stage separator and loses inertia and falls into the dus...
