The filter element connection plate 701 is attached to the side surface of the modular filter element assembly rack 3. The positioning buckle 306 is at the same height as the filter element socket 304. The end of the filter element connection plate 701 is clamped with the positioning buckle 306, so that the pull-out air filter element 7 is stably positioned. After the positioning buckle 306 is bent outward, the filter element connection plate 701 is disengaged from the limit, which is convenient for the pull-out air filter element 7 to be disassembled from the inside of the modular filter element assembly rack 3.

[0025] In an embodiment of the present disclosure, the insertion track 305 is at the same height as the filter element socket 304. The insertion track 305 is parallel to the bottom surface of the modular filter element assembly rack 3. The pull-out air filter element 7 is inserted into the insertion track 305. The edge of the pull-out air filter element 7 is in close sliding connection with the filter element socket 304, ensuring that the pull-out air filter element 7 is inserted or pulled out straight from the inside of the modular filter element assembly rack 3, and ensuring good sealing between the pull-out air filter element 7 and the modular filter element assembly rack 3 to avoid air leakage.

[0026] In an embodiment of the present disclosure, the built-in partition rack 5 is located at the central position inside the modular filter element assembly rack 3. Two partition guide rods 501 are respectively vertically arranged on the left surface and the right surface of the built-in partition rack 5. The outer ends of the partition guide rods 501 are fixedly connected to the inner side walls of the modular filter element assembly rack 3. The internal space of the modular filter element assembly rack 3 is divided into two channels by the built-in partition rack 5. One pull-out air filter element 7 is installed in each of the two channels to purify the air passing through the channel.

[0027] Embodiment 2. On the basis of Embodiment 1, convex structures are provided at the front end and the rear end of the bottom plate of the self-sealing push plate 6. The convex structures at the end of the self-sealing push plate 6 are slidably connected to the insertion track 305. An air baffle 601 is vertically installed on the side of the self-sealing push plate 6 close to the built-in partition frame 5. The air baffle 601 is parallel to the lower surface of the modular filter element assembly frame 3. The air baffle 601 is attached to and slidably connected to the built-in partition frame 5. Two push plate guide openings 602 are formed through the left and right of the self-sealing push plate 6. Two reset tension springs 603 are fixedly connected to the outer surface of the self-sealing push plate 6. The two reset tension springs 603 are respectively located at the opening positions of the two push plate guide openings 602. The push plate guide openings 602 are slidably connected to the partition guide rods 501. The partition guide rods 501 pass through the reset tension springs 603. The outer ends of the reset tension springs 603 are fixedly connected to the inner side walls of the modular filter element assembly frame 3. During the disassembly process of the pull-out air filter element 7, as the pull-out air filter element 7 is pulled outwards, the self-sealing push plate 6 moves outwards following the pull-out air filter element 7 under the pulling force of the reset tension spring 603 and remains in contact with the inner edge of the pull-out air filter element 7. When the pull-out air filter element 7 is completely pulled out, the self-sealing push plate 6 is inserted into the filter element socket 304 under the pulling force of the reset tension spring 603, and the push plate guide opening 602 seals the gap generated by the pull-out of the pull-out air filter element 7, preventing air from leaking through the gap. In this state, this channel is blocked, and the air entering the modular filter element assembly frame 3 will flow through another channel and be purified by another pull-out air filter element 7. The operation of the purification device will not be affected during the process of replacing the pull-out air filter element 7, enabling the purification device to replace the pull-out air filter element 7 while in the powered-on state.

[0028] Working principle of this embodiment: First, the user selects a modular filter element mounting rack 3 with different functions according to the usage requirements, and docks and installs it above the air guiding box 1 from top to bottom, so that the centering inner flange 301 is inserted into the opening inside the upper part of the air guiding box 1. The modular filter element mounting rack 3 is docked above the air guiding box 1 through the magnetic attraction connection between the box docking iron ring 103 and the docking magnetic ring 302. The purification device is turned on, and the fan 2 starts to guide the air in the space above the air guiding box 1 into the air guiding box 1 and discharges it from the clean air exhaust port 101, so that the external air passes through the intake grille 4 and enters the modular filter element mounting rack 3, and flows downward through the pull-out air filter 7 for filtration. When it is necessary to use filters with multiple functions for air purification, the modular filter element mounting racks 3 with the required function filters are assembled. The centering inner flange 301 of the upper modular filter element mounting rack 3 is inserted into the top opening of the lower modular filter element mounting rack 3, and the two modular filter element mounting racks 3 are combined into one for use through the magnetic attraction connection formed by the docking magnetic ring 302 of the upper modular filter element mounting rack 3 and the mounting rack docking iron ring 303 of the lower modular filter element mounting rack 3. When it is necessary to replace the pull-out air filter 7, the external positioning buckle 306 where it is located is bent outward, and the pull-out air filter 7 and the self-sealing push plate 6 slide outward under the pulling force of the return spring 603. When the pull-out air filter 7 is completely pulled out, the self-sealing push plate 6 is inserted into the filter element socket 304 under the pulling force of the return spring 603, and the push plate guide port 602 seals the gap generated by the pulling out of the pull-out air filter 7 to prevent air from leaking through the gap. In this state, this channel is blocked, and the air entering the modular filter element mounting rack 3 will flow through another channel and be purified by another pull-out air filter 7. By replacing and installing the pull-out air filters 7 on both sides in this way, the replacement of the device filter element can be completed, and the operation of the purification device can be prevented from being affected during the process of replacing the pull-out air filter 7, and the filter element can be replaced in the power-on state.

[0031] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure.
