Multi-stage cyclone machanism and dust cup structure

Abstract

The present invention discloses a multi-stage cyclone machanism which comprises an independent first stage cyclone cylinder, a first stage cyclone net cover arranged in the first stage cyclone cylinder, and a second stage cyclone turbine component in the first stage cyclone net. A first stage cyclone space is formed between the first stage cyclone cylinder and the first stage cyclone net cover, and the first stage cyclone cylinder is detachably installed outside the second stage cyclone turbine component. One side of a first stage cyclone cylinder side wall close to the bottom is provided with a first stage dust throwing opening, and the top of the first stage cyclone cylinder side wall is provided with a first stage cyclone air inlet. The first stage cyclone cylinder is designed as an independent cyclone cylinder structure, and a simple partition is formed between the bottom of the first stage cyclone cylinder and the first stage cyclone net cover. The dust thrown from the first stage dust throwing opening is rotated to the opposite side of the first stage dust throwing opening along a dust cup wall, since the first cyclone space at the opposite side and the first dust cylinder are isolated, thus the dust loses power to fall to the bottom of the first stage dust cylinder to maintain relative stationary, the dust back sucking of the first stage cylinder is effectively prevented, and the filtering efficiency of the whole dust cup is improved.

Description

technical field [0001] The invention belongs to the technical field of vacuum cleaner production, and in particular relates to a multi-stage tornado cyclone mechanism and a vacuum cleaner with the multi-stage tornado cyclone mechanism. Background technique [0002] The dust and gas separation mode of the dust collection part of the vacuum cleaner mostly adopts the first-stage centrifugal separation mode or the dust bag filter mode. The filtration efficiency of these two separation modes is low and easy to block. At present, there is also a multi-stage tornado vacuum cleaner dust cup, which adopts a two-stage separated body, generally including two-stage dust and gas separation structures, the first-stage structure is used to filter large-scale dirt in the air, and the second-stage structure is used for separation and collection For small dust particles and other debris, the secondary dust and gas separation structure generally forms a secondary cyclone through the cooperatio...

Problems solved by technology

[0003] At present, the first-level cyclone space of the traditional multi-level tornado system is composed of the main body of the dust cup and the first-level cyclone net cover, so that the first-level ash storage space and the first-level cyclone space are in the same space. This multi-level tornado system The disadvantage is that the primary cyclone space throws most of the ash into the primary ash storage space through centrifugal force, and at the same time, the dust in the ash storage space is easily carried into the secondary cyclone net cover with mesh holes. Cyclone system, resulting in a decline in the filtration level of the entire dust cup, especially for the hand-held dust cup structure with a smaller dust cup height, the above situation is more likely to occur, thus affecting the dust collection efficiency of the vacuum cleaner

[0004] Therefore, the industry urgently needs a new type of independent multi-stage tornado cyclone structure to solve the problem that dust easily falls into the cyclone system from the ash-containing space.
