Problems solved by technology

[0004] At present, the air filter has the problems of large volume, large installation interface, small filter area, large resistance and rapid increase, and the need to replace the filter frequently. At the same time, due to the large volume and large air intake interface, the integration of the filter in the filter device is affected.

Embodiment 1

[0020] A compact air filter such as figure 1 As shown, it includes a frame body 1, the four sides of the frame body 1 are closed up, down, left, and right, and a filter layer is installed on the front side of the frame body 1 2 and the protective net 4, the filter layer is installed on the rear side of the frame body 1 3 and guard net 4. The filter layer 2 is a low-efficiency filter layer; the filter layer 3 is a high-efficiency filter layer.

[0021] This structure can achieve two-stage filtration, the polluted air first passes through the filter layer Filter the aerosol with larger particles, and then pass through the filter layer All the aerosols with small particles are filtered out to obtain clean air, and two-stage filtration is realized to prevent the filtration resistance of the single-layer high-efficiency filter layer from increasing too fast and prolong the service life.

Embodiment 2

[0023] A compact air filter, comprising a frame body 1, the upper and lower sides of the frame body 1 are closed, such as image 3 As shown, the left side or the right side of the frame body 1 is equipped with an air inlet plate 6 through a special-shaped connector 5, and the middle part of the air inlet plate 6 is provided with an air inlet 7 that can be opened and closed.

[0024] Such as figure 2 As shown, the filter layer is installed on the front side of the frame body 1 2 and the protective net 4, the filter layer is installed on the rear side of the frame body 1 3 and guard net 4.

[0025] The filter layer 2 is a high-efficiency filter layer; the filter layer 3 is a high-efficiency filter layer. The polluted air enters through the air inlet and is filtered through the filter layers on both sides to obtain clean air.

[0026] When the middle air intake is adopted, the front and rear sides are air outlets. When adopting two-stage filtration, close the air ...

Abstract

The invention discloses a compact air filter, comprising a frame body (1), wherein the upper, lower, left and right four side surfaces of the frame body (1) are closed, a filtering layer I (2) and a protecting wire net (4) are mounted on the front side in the frame body (1), and a filtering layer II (3) and a protecting wire net (4) are mounted on the back side in the frame body (1). An air inlet plate (6) is mounted on the left side surface or right side surface of the frame body (1) through a special-shaped insert part (5), and air inlets (7) which can be closed are formed in the middle part of the air inlet plate (6). The compact air filter adopts a structure of one frame with two elements, reduces the mounting interface, increases the filtration area, reduces resistance, improves the filtering quality, prolongs service life, and facilitates integrated application of the device; and simultaneously, by change of the air inlet interface and staged arrangement of the filtering elements to realize two-stage filtration, one structure with two functions is realized, the external dimensions of the air filter are reduced, and the service life of the air filter is prolonged.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to a compact air filter, which realizes two purposes. Background technique [0002] The air filter is a filter made of filter material, which can effectively filter out aerosols such as dust, smoke, and fog in the air, and realize the filter for air purification. It is widely used in electronic industry, pharmaceutical industry, military protection and other fields. [0003] In order to increase the effective area and optimize the filtration performance of the air filter, its structural form has been developed from the original single plate shape to cylindrical shape, long cylindrical shape, and matrix shape. It mainly enters the air through one side, and after being filtered by the filter material, the clean air goes out from the other side to realize the function of filtration and purification. [0004] At present, the air filter has the problems of large volume, large installati...
