[0001] The present application relates to the technical field of filter cartridges, and more specifically, to an air filter cartridge. Background Art

[0002] 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. At present, in order to ensure the air quality, air filters are used in many fields to filter the air. For example, clean rooms need to use filters to purify the air, and the filter element is an important component in the filter to filter impurities.

[0003] According to the search, the Chinese patent with patent number CN220355710U discloses an air filter element, including a bracket, the tops of both sides of the bracket are fixedly connected with a shell, the inner cavity of the shell is plugged with an L-shaped plug rod, the bottom of the L-shaped plug rod is fixedly connected with a first magnet, the shell and the L-shaped plug rod are fixedly connected by mounting bolts, one end of the L-shaped plug rod is fixedly connected with a connecting plate, the bottom of the connecting plate is fixedly connected with a filter element body, both sides of the bottom of the inner cavity of the shell are fixedly connected with a limiting block, the top of the limiting block is provided with a groove, and the bottom of the inner cavity of the groove is provided with a second magnet. The utility model solves the problem that the existing filter element is extremely troublesome when disassembling and assembling, and is extremely inconvenient when the filter element needs to be regularly cleaned and replaced, resulting in a significant reduction in the filtering effect of the filter element, and even clogging.

[0004] With respect to the above-mentioned related technologies, the applicant believes that, when the above-mentioned filter element is in use, although it can achieve a certain degree of convenient disassembly compared with the prior art, during the installation process, it still uses mounting bolts to assist in installation and fixation. Therefore, when disassembling and replacing the filter element body, it is necessary to disassemble and assemble multiple mounting bolts. As a result, compared with the prior art, the ease of operation when replacing the filter element body has not been greatly improved, and it is still not convenient for the staff to quickly disassemble and install it. For this reason, we propose an air filter element. Utility Model Content

[0037] When it is necessary to remove the filter element body 140, the staff holds the handle 260 and then uses their fingers to manipulate the connecting component 240 inside the unlocking slot 230. The connecting component 240 will simultaneously drive the two snap-fit ​​components 220 to push out the four slots, thereby releasing the lock on the filter element body 140. Subsequently, the hollow plate 130 is pulled upward by the handle 260 to make the filter element body 140 slide out of the U-shaped limit slot 150, thereby completing the removal of the filter element body 140. Subsequently, the staff cleans the filter element body 140, inserts the filter element body 140 back into the U-shaped limit slot 150 after cleaning, and releases the connecting component 240 to reset the connecting component 240, thereby allowing the connecting component 240 to drive the two snap-fit ​​components 220 to re-enter the four slots, completing the installation of the filter element body 140, making the removal of the filter element body 140 convenient.

[0039] Pull the two control blocks 242 closer to each other and press the second spring 243 to contract, so that the second connecting arm 244 pushes the conversion block 226 to move. The conversion block 226 pushes the two movable blocks 222 away from each other through the two first connecting arms 227 and presses the first spring 225, so that the two card blocks 224 are withdrawn from the slots, thereby releasing the lock on the filter element body 140. Subsequently, the hollow plate 130 is pulled upward by the pull handle 260, so that the filter element body 140 slides out of the U-shaped limit groove 150, thereby completing the disassembly of the filter element body 140.

[0040] The unlocking assembly 250 includes an installation groove opened at the top of one of the control blocks 242, and through grooves are opened on both sides of the inner wall of the installation groove.

When the two control blocks 242 are reset, the elastic force of the two third springs 252 drives the movable plate 251 to rise, and at the same time, the locking block 253 is inserted back into the hollow plate 130 to re-lock the control block 242 to avoid accidentally unlocking the filter element body 140. At the same time, the four limit rods 280 will be inserted into the four limit holes 270, thereby limiting the hollow plate 130, making the installation of the filter element body 140 more stable, making the disassembly and assembly of the filter element body 140 more convenient, and facilitating the operation of the staff.
