Description

Technical Field

[0001] The utility model belongs to the technical field of air filters, and specifically refers to an air filter for a magnetic levitation fan. Background Technique

[0002] An air filter, as an important part of a gas purification system, mainly functions to filter dust, particles and other impurities in the air to ensure that the gas entering the internal parts of mechanical equipment is clean and pollution-free. In a magnetic levitation fan system, the role of the air filter is particularly crucial, which is directly related to the operating efficiency and stability of the fan, as well as the service life of the internal parts of the equipment.

[0003] In traditional inlet filtering devices of magnetic levitation fans, a mechanical fixed structure is generally used to install the air filter. During the actual operation of such devices, due to the need to face a complex and changeable gas environment, the air filter is prone to accumulating dust and particles, thus affecting its filtering effect and ventilation volume. Therefore, it is necessary to regularly disassemble and clean the air filter.

[0004] However, the traditional disassembly process is relatively cumbersome. First of all, it is necessary to manually remove multiple fixing screws or buckles. This process is not only time-consuming and laborious, but also there is a risk of screw loosening or buckle damage. Secondly, when reinstalling the air filter, it is also necessary to ensure that each fixing part is installed in place, otherwise problems such as air leakage or filter loosening may occur. Content of the Utility Model

[0005] In order to solve the above problems, the utility model proposes an air filter for a magnetic levitation fan.

[0006] The technical solution adopted by the utility model is as follows: The utility model provides an air filter for a magnetic levitation fan, including a filter housing.

At this time, the second limiting plate 13 and the first limiting plate 12 that fix the air filter element 2 are moved away. Take out the air filter element 2 from the frame-shaped edge 6, clean it and then reinstall it on the frame-shaped edge 6. Then rotate the turning handle 18 in the reverse direction until the second magnet 20 and the third magnet 21 adsorb, and the fifth magnet 23 and the sixth magnet 24 adsorb, completing the fixation of the air filter element 2. The above is the overall working process of the present utility model. Just repeat this step during the next use.
