Description

Dust cup of drop height centrifugal type dust collector

Technical field

The utility model 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 utility model 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, technical solution adopted in the utility model 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 the flaring internal orifice that goes out 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 the utility model air air inlet 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.
