They provide a highly clean production or research environment by disassembling and combining different modules. They are widely used in optoelectronics, electronics, food, pharmaceuticals, and healthcare, among other fields. The air filtration structure used in cleanroom air purification processes is a component that filters and purifies the air. It typically includes a fan, filter, and ventilation ducts.

[0003] In the process of air circulation and filtration in existing modular dust-free workshops, filters are all installed in a fixed manner and installed in the ventilation duct through bolt threads. After installation, they are not easy to disassemble, making it inconvenient to clean or repair and replace them, which may affect the filtration effect. Utility Model Content

[0008] Furthermore, a handle is provided at the end of the outer side surface of the sealing plate, the inner end of the sealing plate is a magnetic plate structure, and the inner end of the inspection window is a magnetic groove structure that is magnetically attracted to the magnetic plate structure.

[0009] Furthermore, one side of the first frame is an open structure, and auxiliary slide grooves are provided at the upper and lower ends of the first frame close to the open structure. Auxiliary sliders are provided at the upper and lower ends of the fan for sliding connection with the auxiliary slide grooves. The auxiliary sliders and the auxiliary slide grooves are provided with interconnected magnetic grooves, and the two magnetic grooves are connected by the magnetic pins.

[0010] Furthermore, square card slots are provided on both sides of the front end face of the second frame, and square magnetic blocks adapted to the square card slots are provided on both sides of the filter screen. One side of the front end face of the second frame is rotatably connected to a magnetic limit plate that is magnetically attracted to the square magnetic block, and a pull hole is provided on the magnetic limit plate.

[0011] Furthermore, the lower end surface inside the ventilation duct is respectively provided with a first slide groove and a second slide groove, and the lower end surfaces of the first frame and the second frame are respectively provided with a first slider and a second slider, the first screw rod and the second screw rod rotate in the first slide groove and the second slide groove respectively, the first screw rod and the second screw rod are respectively threadedly connected to the first slider and the second slider, and the outer ends of the first screw rod and the second screw rod are both provided with handles.

[0012] Furthermore, a mounting plate is provided at one end of the ventilation duct close to the fan, and a plurality of mounting holes are opened on the mounting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the fan needs to be repaired, the magnetic pin is pulled out from the two magnetic slots, and the fan is directly pulled out of the first frame for repair. After the repair is completed, the fan is directly slidably connected to the first frame. When the fan is fully pushed into the inside of the first frame, the two magnetic slots are connected, and the magnetic pin is inserted into the two magnetic slots to fix it. When the filter needs to be cleaned or replaced, the magnetic limit plate is pulled to rotate so that it does not collide with the square magnetic block, and then the filter is directly pushed out of the second frame 7, and a new filter is taken. The square magnetic blocks on both sides are used to clip into the square slots on both sides of the second frame, and the magnetic limit plate is released. The self-weight and magnetic force are used to make it magnetically offset with the square magnetic blocks, thereby realizing quick replacement of the filter, facilitating quick and convenient disassembly and assembly of the filter ventilation mechanism, thereby facilitating cleaning or repair and replacement of the air filter structure to avoid affecting the filtering effect.

[0015] 2. When the first frame with the fan needs to be adjusted as required, the first screw rod is rotated to rotate in the first slide groove and the first slider, thereby driving the first frame and the fan to be adjusted to the corresponding position in the ventilation duct. When the position of the filter needs to be adjusted, the second screw rod is rotated to rotate in the second slide groove and the second slider, thereby driving the second frame with the filter to slide and adjust in the ventilation duct. This makes the present application not only easy to disassemble and assemble, but also can adjust the position of the fan and the filter according to ventilation and filtration requirements, with high flexibility.
