Description

Technical Field

[0001] The present invention relates to the technical field of air filtration, and more particularly to a low-resistance baffle filter. Background Art

[0002] The partition filter is a key component commonly used in air purification systems, especially in clean rooms, laboratories, hospitals and other places with high requirements on air quality. It uses aluminum foil or paper partitions inside to fold the filter material into a corrugated shape to form a uniform air flow channel, which can increase the filtration area and improve the filtration efficiency. It can filter out more than 99.97% of particles of 0.3 microns and above in the air, and is suitable for various air purification systems.

[0003] Referring to the Chinese patent case with authorization announcement number CN220758464U, a partition-type air filter for air purification is disclosed, which belongs to the field of air filtration technology and includes a box body, the box body has a section fixedly connected to an air inlet box, a partition plate is fixedly connected between the box body and the air inlet box, an air inlet is arranged inside the partition plate, an air outlet is arranged on the right side of the box body, an opening is arranged on the top of the box body, a filtering device is snap-connected inside the opening, and an air suction device is fixedly connected inside the air inlet box. The utility model removes the limit plate from the device by pulling the overall handle. When the limit plate is taken out, the fixed frame and the filter plate will be taken out of the device together, disconnect the connection between the filter device and the limit plate, pull the component handle, and take the connecting block out from the inside of the isolation plate. When the connecting block is taken out, the filter plate will be taken out of the limit plate along with the connecting block, and the disassembly of the device is completed. Then, the filter plate can be cleaned or replaced. However, in the above case, the filter plate can only be cleaned by taking it out. However, frequent taking and placing will affect the stability of the filter plate installation, causing the filter plate to shake, thereby reducing the service life of the filter plate.

At the same time, the pull rod 2309 will also push the slider 2313 to slide to the position of the oblique edge of the guide block 2312. After that, when the air in the airbag trigger assembly is withdrawn, the edge strip 2302 loses its support. Under the push of the extrusion spring 2305, the edge strip 2302 will quickly reset, and the slider 2313 will also slide along the oblique edge of the guide block 2312 to the initial position. During the resetting process of the edge strip 2302, the filter plate assembly 21 inside it can be pushed to shake violently, thereby shaking off the dust in the filter plate assembly 21, achieving the purpose of self-cleaning and facilitating daily maintenance.
