Description
Technical field
The present invention relates to a kind of dust catcher parts, especially a kind of dirt cup that is used for cleaner dust-collection.
Background technology
General dust catcher all is to utilize the vacuum principle, and the air or the foreign material that will contain dust enter dirt cup air inlet from tangential direction, produces centrifugal eddy current in the dirt cup, makes more greatly, heavier particle or dirt be deposited on dirt cup bottom, and then dirt is cleared up.In order to make the dirt cup produce bigger eddy current, often load onto the sedimentator that offers air inlet at dirt cup center, the air inlet of this sedimentator is often corresponding with the air inlet of dirt cup, therefore the centrifugal force that produces in the dirt cup is big inadequately, for example the patent No. is " 01144390.1 ", " dust collector box of vacuum cleaner ", this disposal box is because the dust separation effect is not ideal enough, so fine dust is easy to directly go out from the air outlet of disposal box by the air inlet of sedimentator, like this, the filter that is placed on the disposal box air outlet is stopped up by fine dust, increase the dust suction resistance of motor, heavy then can burn out motor, light then can influence the serviceability of dust catcher.In order to improve the effect of separation of air and dust, the centrifugal dirt cup that twice separation of design also arranged, because it is made up of two different separators, though separating effect is better, but the shared volume of two separators is bigger, thereby influenced the dirt chamber capacity of dirt cup, increased the dust catcher volume, increased cost of material.
Summary of the invention
Defective and the deficiency of the present invention in order to overcome above-mentioned prior art, for the dust catcher industry provide a kind of can effectively filtering fine dust with other foreign matter, separate filter dirt dust cup of dust collector effective, simple in structure.
For achieving the above object, the technical solution used in the present invention is: this dust cup of drop height centrifugal type dust collector comprises cup, be arranged on air outlet on the cup and the air inlet tangent with the cup perisporium, place the separator of cup inside, this separator is by discharge pipe, the air inlet that is opened on the discharge pipe tube wall is formed with the cage that is sleeved on discharge pipe air inlet below, the air inlet of discharge pipe communicates with the air outlet of cup, and there is certain drop height h the air inlet center on the cup and the upper edge of discharge pipe air inlet; This drop height h with 0-140mm for well; Described separator is by the tubaeform air outlet in upper end, is held on the dirt cup to be connected with the dirt cup, and the bowl cover and the cup that have the cup air outlet cover, and is fixed on cage horn mouth on the discharge pipe towards cup bottom dust-collecting cavity; Between the air outlet of discharge pipe and cup air outlet, filter is housed.The air outlet of described cup also can be arranged at the bottom, and the separator in the cup is fixed on the cup top by the discharge pipe upper end, and the discharge pipe of cage below extends downwards and connects into flaring air outlet with bottom of cup; Pad is equipped with filter outside the air outlet of bottom of cup.
There is certain drop in the air inlet of air air inlet of the present invention and separator discharge pipe, make the certain draught head of generation between two air inlets, add cage top and also there is certain draught head in the cage bottom, therefore after the air that has a dust enters the dirt cup, promptly produce downward spiral and quicken whirlwind, dust is subjected to centrifugal force and gravity effect to be thrown toward perisporium and falls to cup dust-collecting cavity bottom.Because the partition effect of cage, the dust that falls into dust-collecting cavity is difficult to be subjected to the influence of top spiral whirlwind and rolls again.Have only the tiny dust particle of minute quantity to be deposited on the filter with the air outlet of discharge pipe, the effect of dust-separating has improved greatly, it have simple in structure, cost is low, the characteristics that volume is little.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an another kind of structural representation of the present invention.
The specific embodiment
Fig. 1 is a kind of embodiment of the present invention.
Shown in the accompanying drawing, this dust cup of drop height centrifugal type dust collector comprises cup, and cup perisporium top tangentially offers air inlet 4, and bowl cover is stamped at the top of cup, and cleaned air passes air outlet 6 just is opened on the bowl cover.Cup inside is equipped with a separator, and this separator is made up of discharge pipe 1, the cage 3 that is opened in the air inlet 2 on the discharge pipe tube wall and is sleeved on discharge pipe air inlet below.Air outlet 5 flares of discharge pipe, this is tubaeform, and the air outlet outer is held on that cup is suitable for reading, makes it to be connected with cup.Have certain drop height between air inlet 6 centers of cup and the air inlet 2 of discharge pipe 1, this drop height can be 0-140mm.Between air outlet on the cup bowl cover 6 and discharge pipe air outlet 5, filter is housed.Be sleeved on the cage flare on the discharge pipe, its horn mouth is toward the dust-collecting cavity of cup bottom.
Fig. 2 is another kind of embodiment of the present invention.
Shown in the accompanying drawing, this dust cup of drop height centrifugal type dust collector, the air outlet 6 of its cup and the air outlet 5 of discharge pipe 1 are opened in the bottom, separator discharge pipe 1 top in the cup directly and the cup top fix, the discharge pipe 1 of cage below extends downwards and connects into tubaeform air outlet 5 with inner cup portion, makes bottom of cup air outlet 5 tops form the dust-collecting cavity of cup simultaneously.The cup air outlet is equipped with filter outward.All the other structures are same as the previously described embodiments.
During dust catcher work, produce negative pressure in the dirt cup because electric fan makes, the air and the dirt of band dust enter from the air inlet 4 that is opened in dirt cup tangential direction.Because there is certain drop height in the air inlet 2 on the separator discharge pipe with dirt cup air inlet 4, make the certain draught head of generation between two air inlets, add cage top and also there is certain draught head in the cage bottom, therefore after the air that has a dust enters the dirt cup, promptly produce downward spiral and quicken whirlwind, dust is subjected to centrifugal force and gravity effect to be thrown toward perisporium and falls to cup dust-collecting cavity bottom.Because the partition effect of cage 3, the dust that falls into dust-collecting cavity is difficult to be subjected to the influence of top spiral whirlwind and rolls again.Purifying air after the separation enters the air inlet 2 of separator discharge pipe 1, enters electric fan through the tubaeform air outlet 5 of discharge pipe by filter and dirt cup air outlet 6, discharges outside the dust catcher.
