[0002] The air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It purifies the low-dust air and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room;

[0003] An air filter is a commonly used air purification device. An air filter is usually composed of a filter element and an outer frame. Air passes from one side of the filter element to the other side of the filter element. The air can be filtered and purified through the filter element, and the outer frame is used to place the filter element in it and fit tightly against the side end of the filter element to reduce the air flowing through the gap between the outer frame and the filter element to ensure the filtering effect.

[0004] For example, the utility model with application number 202320156309.4 discloses an outer frame structure and an air filter device, which is suitable for an electric clamp-type cold-cut flying saw machine, wherein one end of the first mounting plate provided with a first adhesive layer is abutted against one end of the second mounting plate provided with a second abutment plate, the first adhesive layer and the second abutment plate abut and bond to each other, and the second abutment plate is provided between the two first side plates. The outer frame structure can reduce the difficulty of the operator in the subsequent connection of the first mounting member and the second mounting member, and ensure the processing quality of the outer frame structure. However, similar to the outer frame structure in the above-mentioned document, when a single person is required to operate, its structural docking is relatively time-consuming and laborious, and structural displacement may occur during the installation process, requiring later adjustment, and at the same time, the structural joint lacks certain protection.
