Description

The multistage cyclone dust arrester that is used for vacuum cleaner

Technical field

The utility model patent relates to a kind of dust arrester, relates in particular to a kind of multistage cyclone dust arrester that is used for vacuum cleaner.

Background technology

In at present traditional 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, the air intake that has dust tangentially is arranged at the top of cyclone chamber, center of top is air stream outlet (negative pressure source), air-flow rotates the downward sedimentation separation of part dust after tangentially entering 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 enters once more in the ascending air by air-flow easily, causes the dust content in the ascending air big thus, and filter easily stops 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 deficiencies in the prior art, a kind of compact conformation is provided, the efficiency of dust collection height, and has a stronger sustainability dust collection capacity, can effectively reduce pressure and flow loss in the dust removal process, can realize separating of cinder and thin ash, and can hold back the micron order dust, guarantee that the air-flow that dust catcher is discharged is the multistage cyclone dust arrester that is used for vacuum cleaner that does not have secondary pollution.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of multistage cyclone dust arrester that is used for vacuum cleaner, comprise dirt bucket and dirt bung, be provided with air inlet in the described dirt bung, be provided with air outlet in the described dirt bung, described dirt bucket fixes by dirt bucket button mutually with the dirt bung, be provided with cyclone dust removal mechanism in the described dirt bucket, be provided with the cover plate that is complementary with it in the described cyclone body, described cyclone body is provided with the filter cotton fixed mount, be provided with filter cotton in the described filter cotton fixed mount, described filter cotton fixed mount and dirt bung fix, described cyclone dust removal mechanism seals by lower seal mutually with the dirt bucket, described dirt bung seals by last sealing ring mutually with cyclone dust removal mechanism, described cyclone dust removal mechanism comprises cyclone, one-level whirlwind tube and secondary whirlwind tube, be provided with one-level circular cone grid and secondary circular cone grid in the described cyclone, described one-level circular cone grid places one-level whirlwind tube, described secondary circular cone grid places secondary whirlwind tube, be provided with one-level dirt chamber in the described one-level whirlwind tube, be provided with secondary dirt chamber in the described secondary whirlwind tube, described cover plate matches with the top of one-level circular cone grid, described one-level circular cone grid is connected with secondary dirt chamber, and described secondary circular cone grid is connected with filter cotton.

Operation principle: the two-stage dust arrester of rationally arranging in effective space makes it have good dust removing effects; Adopt the two-stage dust arrester, realized separating of cinder and thin ash, can effectively separate micron-sized dust, wherein the structure that throws away on the air intake of primary dust removing device bottom has effectively been utilized the centrifugal action of air-flow, thereby reach the effect of efficient separation, the structure that air intake lower end, two-stage dust removal device top throws away has further been utilized the centrifugal action of air-flow, reaches high separating effect; In addition, the utility model patent can utilize airflow centrifugal power effectively to precipitate dust, has avoided dust to be blocked on the filter course, has kept flow constant of whole system in the dust removal process, thereby has reduced the suction power of conventional cleaners and the loss of pressure.

2. 1. the air-flow that has dust tangentially enter one-level whirlwind tube from air inlet, 2. rotating at a high speed on the screw in the one-level whirlwind tube, dust can 3. throw away from the breach of upper end one-level dirt chamber 4., 5. the circular cone grid of air-flow from one-level whirlwind tube that has a small amount of thin ash make progress, 6. tangentially enter secondary whirlwind tube 7. through the passage in the cyclone again, again secondary whirlwind tube 7. in rotation at a high speed under the screw, thin ash under action of centrifugal force, can throw away from the breach of lower end secondary dirt chamber 8., 10. 9. the circular cone grid of air-flow from secondary whirlwind tube that has the thin ash of only a few upwards go directly filter cotton, 10. the thin ash of only a few is filtered cotton stops, and leading directly to filter cotton, clean air-flow 10. rose, discharge from air outlet numbering 11 again, thereby enter motor.

As preferably, described one-level whirlwind tube and secondary whirlwind tube and dirt bucket fasten.

Therefore, the multistage cyclone dust arrester that is used for vacuum cleaner of the present utility model, simple in structure, efficiency of dust collection height, sustainability height.
