Abstract
The utility model relates to an air filter which comprises a shell and a filter element. The filter element is composed of two layers of porous plates, namely, an inner layer of porous plate and an outer layer of porous plate enclose a barrel shape; a filter medium layer is arranged between the two layers of porous plates; the shell is provided with an air intake porous plate wrapped the outside of the filter element; the two ends of the shell is provided with seal covers; the filter element is pressed tightly and fixed by the seal covers at the two ends of the shell; one end of the filter element is provided with an open outlet and the other end is sealed; the seal covers which are abutting joint with the outlet end of the filter element are provided with air exhaustion ports; and the end face on which the outlet end of the filter element is in abutting joint with the seal covers is provided with a sealing ring. The seal of the air filter is close and the filtration effect is good. Besides, the shell seal covers are connected with the shell through adjusting screw threads so that the adjustment of the seal covers can lead to the seal pressure between the filter element and the seal covers, and then the seal effect is ensured.
Description
Technical field
The utility model relates to a kind of filter, particularly a kind of air cleaner.
Background technology
The critical piece of air cleaner is a filter core, and the filter core of air cleaner is provided with filtering medium layer by the cylindrical shape that inside and outside two-layer orifice plate surrounds in the prior art between two-layer orifice plate.During use, the two ends of filter core will guarantee and its body seal simultaneously, though all be provided with sealing device between filter core two ends and its shell, because filter usually needs to take off to clean, sealing place is aging easily, cause poorly sealedly, lose filtration.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of air cleaner tight, good filtration effect that seals.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of air cleaner, comprise shell and filter core, filter core surrounds cylindrical shape by inside and outside two-layer orifice plate, between two-layer orifice plate, be provided with filtering medium layer, shell is provided with and wraps in the outer air inlet orifice plate of filter core, two ends at shell are provided with capping, filter core is fixed by the capping at shell two ends, be characterized in: an end of described filter core is provided with unlimited outlet, the other end is a blind end, and the capping that connects with the filter core port of export is provided with the interface of giving vent to anger, and is provided with sealing ring on the filter core port of export and end face that capping is docked.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, is provided with sealing device on the end face of the blind end of filter core.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the outside of shell two ends capping all is fixed with convenient four directions or the hexagon pylon of regulating, and the described interface of giving vent to anger is the screwed hole that is located at the pylon middle part.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, have at least in two cappings of shell one with shell between be threaded by adjusting, end at shell is provided with internal thread, and above-mentioned capping is provided with the external screw thread of regulating with the outer casing end screw-internal thread fit.
The utility model compared with prior art, an end of filter core is outlet, other end sealing, the capping by the shell two ends compresses sealing, tight, the good filtration effect of its sealing.Its shell capping is joined with shell by regulating screw thread in addition, can adjust sealing load between filter core and the capping by the adjusting capping like this.Guarantee sealing effectiveness.
