TECHNICAL FIELD
[0001] The utility model relates to a respirator for plastic bucket cover. BACKGROUND
[0002] At present, some products with large demand are usually stored in plastic barrels, but the cover of the plastic barrel is usually a sealed structure, and the internal pressure of the barrel body is easily affected by the external environment such as temperature, and the pressure change is too large, which may cause the barrel body to deform or burst, and there is a certain safety hazard. Therefore, a breather needs to be installed on the barrel cover to balance the internal and external pressure of the barrel body, avoid internal negative pressure or overpressure of the barrel body, and prevent the barrel from deforming or bursting.
[0003] At present, the existing pressure balancing method is usually to open a small air hole on the barrel cover, and the internal and external gas exchange of the barrel body is carried out through the air hole of the barrel cover to adapt to the internal pressure change of the barrel body, but this method is easy to cause impurities to enter the internal barrel, causing the internal barrel product to be contaminated. SUMMARY
[0004] The technical problem to be solved by the utility model is to provide a respirator for plastic barrel cover, which can balance the pressure of the barrel body while intercepting external dust and impurities, and ensure that the internal material of the barrel body is not contaminated.

[0007] The filter body is connected with the internal clamping piece of the barrel cover through the clamping connection of the boss on the edge of the bottom of the filter body.
[0008] The upper part of the cover plate connecting piece is a conical guide-in part, the bottom of the conical guide-in part protrudes from the outer edge of the cover plate connecting piece and forms a first clamping block between the outer side wall of the top of the cover plate connecting piece; and a second clamping block in a stepped form is arranged on the inner side of the cover plate connecting piece.
[0009] The bottom of the cover plate is upwardly provided with an inner groove, and the bottom of the inner groove is a conical flange which is clamped into the inner groove of the conical guide-in part.
[0010] The first limiting table limiting the first clamping block is formed between the convex block and the upper inner recess outer side wall.
[0011] The second limiting table limiting the second clamping block is formed between the inner recess inner side edge and the bottom end surface of the cover plate.
[0012] Thanks to the above technical scheme, the technical progress achieved by the utility model is as follows.
[0013] The utility model provides a kind of breather for plastic bucket cover, simple structure, it is easy to operate, effectively balance the pressure inside and outside barrel, avoid the deformation damage of barrel due to negative pressure or overpressure, and the utility model is filtered by installing filter membrane on filter main part to the impurity in gas, avoid the pollution of the impurity in outside gas to material in barrel, also avoid the impurity in barrel directly discharged into outside environment.
