Description

Vacuum cleaner is used the multistage cyclone dust arrester
Technical field
The utility model is a kind of dust arrester, and particularly a kind of vacuum cleaner is used the multistage cyclone dust arrester.
Background technology
Structure of dust collector of the prior art is simple relatively, but dust removing effects is poor, and noise is bigger simultaneously.
Chinese patent 01134898.4 discloses the rotoclone collector that a kind of vacuum cleaning is used, and comprises utilizing inertia force to accomplish first dust arrester and second dust arrester that utilizes the centrifugal force completion control of dust second time of control of dust for the first time; Be equipped with in first dust arrester and prevent turbulent parts.This structure dust removing effects is relatively poor, and noise is bigger, and service life is relatively low.
In vacuum cleaner, in order effectively dust to be separated from air-flow, various forms of cyclone separators are used in beginning widely.For example, PCT patent application WO98/35602 discloses the device on a kind of Cyclonic vacuum duster, and the air intake tangential that has dust is arranged at the top of cyclone chamber; Center of top is air stream outlet (negative pressure source); The air-flow tangential rotates the downward sedimentation separation of part dust after getting in the cyclone chamber under centrifugal action; Air-flow moves upward from central authorities simultaneously, discharges from the air stream outlet at top through filter.Though said structure can be realized dust separation to a certain degree, the dust that settles down is driven and gets into once more in the ascending air by air-flow easily, causes the dust content in the ascending air big thus, and filter is prone to stop up, and needs often to clean.
For addressing the above problem; Engendered secondary separation device on the market, promptly second level cyclone separator has been set again, increased the aperture of filter simultaneously at the air stream outlet rear of above-mentioned cyclone separator; Tiny dust can pass through filter, to alleviate the stopping state of filter.Yet the problem that one-level cyclone separative efficiency is not high is difficult to solve all the time, simultaneously how the secondary cyclone is set, and makes it reach good dust removing effects, is still a problem demanding prompt solution.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, and is simple in structure, and a kind of compact conformation is provided; Efficiency of dust collection is high; And having stronger sustainability dust collection capacity, pressure and the vacuum cleaner of flow loss that can effectively reduce in the dust removal process are used the multistage cyclone dust arrester, can realize separating of cinder and thin ash; And can hold back the micron order dust, guarantee air-flow that dust catcher is discharged be do not have secondary pollution vacuum cleaner use the multistage cyclone dust arrester.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of vacuum cleaner is used the multistage cyclone dust arrester; Comprise dirt bucket mechanism and cyclone body, be provided with cyclone body in the described dirt bucket mechanism, described dirt bucket mechanism comprises the dirt bucket; The bottom of described dirt bucket is provided with dirt bucket lower cover; The top of described dirt bucket is provided with dirt bucket middle cover, and the top of described dirt bucket middle cover is provided with dirt bucket loam cake, is provided with the air intake filtering frame between described dirt bucket loam cake and dirt bucket middle cover; The sidewall of described dirt bucket is provided with dirt bucket air inlet, is provided with dirt bucket air outlet in the described dirt bucket loam cake; Described cyclone body comprises cyclone; Be provided with the secondary cyclone in the described cyclone; Described secondary cyclone is located by connecting through the cyclone cover plate with cyclone mutually, and the lower end of described secondary cyclone is with the cyclone cover, and the bottom of described secondary cyclone connects through sprue is stifled mutually; The sidewall of described cyclone is provided with equally distributed filtering holes, is provided with the whirlwind tube in the described secondary cyclone.
As preferably; Described dirt bucket seals through dirt bucket lower cover sealing ring with dirt bucket lower cover mutually; Described dirt bucket lower cover and dirt bucket are interlockingly connected through dirt bucket lower cover button; Described dirt bucket seals through dirt bucket sealing ring with dirt bucket middle cover mutually, and described dirt bucket middle cover seals through dirt bucket middle cover sealing ring with the air intake filtering frame mutually, and described air intake filtering frame seals through dirt bucket loam cake sealing ring with dirt bucket loam cake mutually; Be provided with handle in the described dirt bucket loam cake, described handle and dirt bucket loam cake are buckled through the dirt bucket and are interlockingly connected; The bottom of described cyclone cover is provided with cyclone cover sealing ring, is provided with cyclone cover plate for sealing circle between described cyclone cover plate and cyclone.
Therefore, the vacuum cleaner that the utility model provides is used the multistage cyclone dust arrester, and is simple in structure, improves dust removing effects, has high separating effect, prolongs the life-span of using.
