Abstract

The utility model relates to a dust separator, which comprises an outer cylinder body with a dust wind inlet, wherein the outer cylinder body is also provided with an air outlet channel; the opening part of the air outlet channel, which is arranged in an inner cavity of the outer cylinder body, is provided with an air outlet filter which comprises a filtering screen and a filtering additional layer which is arranged at the filtering screen, and airflow enters one side face of the filtering additional layer; the air outlet filter comprises the filtering screen and the filtering additional layer, through two-stage filtration, the filtering efficiency of the utility model is improved, simultaneously, the burden of the filtering screen is lightened so that when the dust separator operates, the dust attached on the filtering screen is less and the cleaning period of the filtering screen can be prolonged.

Description

Dust separator

Technical field

The utility model relates to a kind of dust separator that is applied on the dust catcher.

Background technology

In the prior art, the dust separator that is applied on the dust catcher generally includes outer cylinder body, have dirt wind inlet and air-out passage on the outer cylinder body, band dirt air-flow enters in the outer cylinder body and carries out dust separation in the inner chamber at outer cylinder body from the dirt wind inlet, and clean gas flow is indoor from the vacuum motor that the air-out passage finally enters dust catcher.Owing to still have a small amount of thin dirt outside in the cylinder lumen in the air-flow behind the dust-separating, so the oral area at the air-out passage in the inner chamber of outer cylinder body is provided with screen pack (as HEPA) usually, thin dirt then is attracted on the screen pack, the user must pull down cleaning with screen pack in use for some time, and because air-flow promptly directly blows to screen pack carry out dust separation in outer cylinder body after, make that the dust that adheres on the screen pack when using is more, cause the cleaning cycle of dust separator shorter, cause trouble to use.

Summary of the invention

The utility model purpose provides a kind of dust separator, and it is less attached to the dust on the screen pack in the course of the work.

For achieving the above object, the technical solution adopted in the utility model is: a kind of dust separator, comprise outer cylinder body with dirt wind inlet, also have the air-out passage on the described outer cylinder body, oral area at the air-out passage in the inner chamber of described outer cylinder body is provided with out wind filter, describedly goes out the attached layer of filtration that wind filter comprises screen pack, the air-flow that is arranged at described screen pack enters a side.

Because technique scheme utilization, the utility model compared with prior art has following advantage: go out wind filter and comprise screen pack and filter attached layer, pass through double-filtration, make its filter efficiency improve, alleviated the burden of screen pack simultaneously, make when the work of this dust separator lessly, can prolong the cleaning cycle of screen pack attached to the dust on the screen pack.

Description of drawings

Accompanying drawing 1 is the cutaway view of bowing of the present utility model;

Accompanying drawing 2 is the cutaway view of the A-A direction in the accompanying drawing 1;

Wherein: 1, dirt wind inlet; 2, outer cylinder body; 3, blast fence; 4, screen pack; 5, whirlwind tube; 6, whirlwind inlet; 7, cyclonic separation inner chamber; 8, filter attached layer; 9, screen pack; 10, go out wind filter; 11, whirlwind outlet; 12, air-out passage.

The specific embodiment

Referring to accompanying drawing 1-accompanying drawing 2, a kind of dust separator, comprise outer cylinder body 2 with dirt wind inlet 1, also have air-out passage 12 on the described outer cylinder body 2, oral area at air-out passage 12 in the inner chamber of described outer cylinder body 2 is provided with out wind filter 10, describedly goes out the attached layer 8 of filtration that wind filter 10 comprises screen pack 9, the air-flow that is arranged at described screen pack 9 enters a side.

Be provided with whirlwind tube 5 in the described outer cylinder body 2 with cyclonic separation inner chamber 7, have whirlwind inlet 6 on the described whirlwind tube 5, also have whirlwind outlet 11 on the described whirlwind tube 5, describedly go out wind filter 10 between described whirlwind outlet 11 and air-out passage 12.Be provided with blast fence 3 in the described outer cylinder body 2, described blast fence 3 retainings are between whirlwind inlet 6 and dirt wind inlet 1.

Dust-contained airflow is in dirt wind inlet 1 enters outer cylinder body 2, in the inner chamber of outer cylinder body 2, because the barrier effect of blast fence 3, make in the dust-contained airflow big grey stall and fall into the inner bottom part of outer cylinder body 2, thin dirt with air-flow bypassed air flow baffle plate 3 backs towards 5 motions of whirlwind tube; Contain of the filtration of the air-flow of the thin dirt of small part, make part be fallen into the inner bottom part of outer cylinder body 2 by isolation with the dust of air-flow bypassed air flow baffle plate 3 motions through screen pack 4; The air-flow that contains thin dirt is from entering in the whirlwind tube 5 from whirlwind inlet 6, and in the cyclonic separation inner chamber 7 of whirlwind tube 5, carry out high efficiency dust separation, make the thin ash in the air-flow fall into the bottom of whirlwind tube 5, the air-flow behind the dust-separating is then screwed out by whirlwind outlet 11.And be the work load that alleviates whirlwind tube 5, to guarantee operating efficiency of the present utility model and pick-up performance, between described blast fence 3 and whirlwind inlet 6, be provided with screen pack 4,, make the big dust of part be fallen in the outer cylinder body 2 by isolation through the filtration of screen pack 4.

In whirlwind tube 5, discharge from whirlwind outlet 11 through the air-flow behind the cyclonic separation dust, through filtering the filtration twin-stage catharsis of attached layer 8 and screen pack 9, make that the air-flow of discharging from air-out passage 12 is a clean gas flow, the vacuum motor that finally enters vacuum cleaner is indoor.That the utility model can be used for is horizontal, on the upright vacuum cleaner, because its high efficiency double-stage filtering effect, make that the cleaning cycle of each filter element (screen pack 9 and filter attached layer 8) is longer, is convenient to alleviate user's burden.
