[0002] The requirement for air cleanliness in some equipment is an important process index. At present, most air filtration devices have a direct connection between the filter element and the inlet and outlet air ducts without an enlarged buffer space, resulting in large filtration pressure loss and low efficiency. Content of the Utility Model

[0003] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide an efficient air filter structure, which has the advantages of a large buffer space and reduced filtration pressure loss.

[0004] To achieve the above purpose, the present utility model provides the following technical solution: An efficient air filter structure includes a lower filter main board. An air outlet bayonet is communicated with the outside of the lower filter main board. An upper filter main board is arranged on the left side of the lower filter main board. An air outlet lower pressing ring is fixedly connected inside the lower filter main board. A filter is arranged inside the upper filter main board. The air outlet lower pressing ring is fixedly connected with the filter. An air inlet bayonet is communicated with the outside of the upper filter main board. An air inlet upper pressing ring is fixedly connected inside the upper filter main board. The air inlet upper pressing ring is fixedly connected with the filter.

[0005] Preferably, a sealing ring is fixedly connected to the left side of the lower filter main board, and the sealing ring is fixedly connected with the upper filter main board.
