Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to an air filter for electrical appliances with an installation structure. Background Technology

[0002] Air filtration refers to air filtration devices, mainly including five types: coarse filters, medium-efficiency filters, high-medium efficiency filters, sub-high efficiency filters, and high-efficiency filters. Each type has different standards and performance levels. Air filters, along with pressure valves and lubricators, are known as the three major pneumatic components, generally used in cleanrooms, factories, operating rooms, laboratories, etc., or for dust prevention in electronic, mechanical, and communication equipment. The main sources of contamination in cleanrooms are microparticles and bacteria. Electrical appliances generate a significant amount of dust during heat dissipation, thus requiring an electrical air filter with a mounting structure.

[0003] Existing devices are complex in structure, inconvenient to install, and cannot adapt to electrical appliances of different sizes. In addition, the filtration methods used are limited and cannot effectively filter the air. Therefore, we propose an air filter for electrical appliances with an installation structure. Utility Model Content

[0004] The purpose of this invention is to provide an air filter for electrical appliances with an installation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An air filter for electrical appliances with an installation structure includes a frame, on both sides of which an installation mechanism is fixedly provided. The installation mechanism includes a limiting groove. Several limiting grooves are opened on both sides of the frame. A limiting post is movably arranged inside the limiting groove. An assembly block is fixedly arranged on one side of the limiting post. A clamping plate is fixedly arranged on one side of the assembly block. A threaded post is fixedly arranged on one side of the assembly block. Slots are opened on both sides of the frame. A bearing is fixedly arranged on one side of the slot. A torsion cylinder is fixedly arranged inside the bearing. A first threaded groove is opened inside the torsion cylinder. An air filtering mechanism is movably arranged at the top of the frame.

[0007] Preferably, the air filtration mechanism includes a combination plate, with the combination plate movably mounted on the top of the assembly frame. A steel wire nylon mesh is fixedly mounted on the bottom of the combination plate, a fiber filter is fixedly mounted on one side of the steel wire nylon mesh, and an activated carbon mesh is fixedly mounted on one side of the fiber filter. Several second threaded grooves are opened at the top of the assembly frame, and bolts are movably mounted inside the combination plate and the second threaded grooves. By placing the combination plate at the top of the assembly frame, with the steel wire nylon mesh at the bottom, the fiber filter on one side, and the activated carbon mesh on one side, and with two second threaded grooves at the top of the assembly frame, the assembly frame is fixed to the assembly frame using bolts. When the appliance is drawing air, the air enters the appliance sequentially through the steel wire nylon mesh, the fiber filter, and the activated carbon mesh. The steel wire nylon mesh intercepts large dust particles, the fiber filter filters small dust particles, and the activated carbon mesh intercepts some airborne bacteria. This three-layer filtration provides excellent filtration results.

[0008] Preferably, a telescopic rod is fixedly installed inside one side of the limiting post, and one end of the telescopic rod is fixedly connected to the inner side of the limiting groove. By welding a telescopic rod inside one side of the limiting post, and welding one end of the telescopic rod to the inner surface of the limiting groove, it is ensured that the limiting post will not detach from the limiting groove.

[0009] Preferably, the first threaded groove is movably connected to the threaded post. By movably connecting the first threaded groove to the threaded post, it is ensured that the threaded post can move inward when the torsion cylinder rotates.

[0010] Preferably, a plurality of connectors are fixedly provided on one side of the assembly frame, and a dustproof plate is fixedly provided on one side of the connectors. By installing two connectors on one side of the assembly frame and providing a dustproof plate on one side of the connectors, dust is prevented from entering the groove.

[0011] Preferably, a rubber anti-slip pad is fixedly provided on one side of the clamp. By using glue to fix the rubber anti-slip pad on one side of the clamp, the friction between the clamp and the electrical appliance can be increased, preventing slippage.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. An air filter for electrical appliances with an installation structure comprises two limiting grooves on each side of a frame, with limiting posts inserted inside the grooves. An assembly block is welded to one side of each limiting post, a clamping plate is welded to one side of each assembly block, and a threaded post is welded to one side of each assembly block. Grooves are formed on both sides of the frame, with bearings welded to one side of each groove. A torsion cylinder is welded to the inside of each bearing, and a first threaded groove is formed inside the torsion cylinder. The threaded post is movably connected to the first threaded groove. The device is installed at the air inlet of the electrical appliance. By rotating the torsion cylinder, the threaded post moves inward, causing the assembly block and clamping plate to move inward. The clamping plates on both sides clamp the electrical appliance, facilitating installation. This mechanism is applicable to electrical appliances of various sizes and is highly practical.

[0014] 2. This type of air filter for electrical appliances with an installation structure consists of a combination plate placed at the top of a frame, a steel wire nylon mesh at the bottom of the combination plate, a fiber filter on one side of the steel wire nylon mesh, and an activated carbon mesh on one side of the fiber filter. Two second threaded grooves are provided at the top of the frame, and bolts are used to fix the frame to the appliance. When the appliance draws air, the air enters the appliance sequentially through the steel wire nylon mesh, the fiber filter, and the activated carbon mesh. The steel wire nylon mesh intercepts large dust particles, the fiber filter filters small dust particles, and the activated carbon mesh intercepts some airborne bacteria. This three-layer filtration provides excellent filtration results. Attached Figure Description
