[0029] The device solves the problem of cumbersome disassembly and assembly process of the filter by setting the snap-on assembly 3 and the limit assembly 6, which is time-consuming and labor-intensive. The filter may move when the air purification device is moved, thereby resulting in poor air purification effect.

[0030] Furthermore, the positioning assembly 4 includes a first movable plate 401, a roller 402 and a placement plate 403. Two sets of slide grooves 8 are provided on the inner wall of the air purifier 1. The rollers 402 are movably connected in the slide grooves 8. The first movable plate 401 is movably connected between the two sets of rollers 402. The placement plate 403 is fixedly connected to the upper surface of the first movable plate 401. The filter plate 5 is clamped in the placement plate 403. A second movable groove 404 is provided in the first movable plate 401. The first knob 405 is rotatably connected in the second movable groove 404. Figure 5 As shown, the structure is used to pull the first movable plate 401 to slide in the positioning groove 7 with the help of the roller 402, so as to pull the first movable plate 401 out of the air purifier 1 and take out the five groups of filter plates 5 together, without the need to disassemble them one by one, thereby improving the disassembly efficiency and cleaning or replacing the filter plates 5 in the placement plate 403.

[0031] Furthermore, the limiting assembly 6 includes a third movable groove 601, a second knob 602, a bidirectional screw 603, a slider 604, a hinge rod 605, a fixed block 606 and a limiting plate 607. A third movable groove 601 is provided at the top of the air purifier 1. The top of the third movable groove 601 is rotatably connected to the outside of the air purifier 1 with the second knob 602.

[0032] Furthermore, the top of the housing 2 is provided with a first movable groove 301 in the air purifier 1, and a clamping plate 302 is movably connected in the first movable groove 301. The clamping plate 302 is T-shaped, and two sets of springs 303 are provided on the upper surface of the clamping plate 302. The two ends of the spring 303 are respectively against the inner wall of the first movable groove 301 and the clamping plate 302. The top surface of the housing 2 is provided with a groove adapted to the clamping plate 302, and the portion of the clamping plate 302 inserted into the housing 2 is arc-shaped. Figure 4As shown, the structure is used to pull the snap-in plate 302 to disengage the lower end portion of the snap-in plate 302 from the groove of the shell 2, so as to facilitate the removal of the shell 2. During installation, the shell 2 only needs to be pushed into the air purifier 1, and the lower end of the snap-in plate 302 is squeezed by the shell 2 to move the snap-in plate 302 upward to contract, causing the spring 303 to deform. When the edge of the shell 2 is completely in contact with the edge of the air purifier 1, the lower end portion of the snap-in plate 302 is inserted into the groove of the shell 2 under the rebound action of the spring 303 to fix the shell 2.

[0033] Furthermore, two sets of second movable plates 407 are movably connected at the upper and lower sides of the second movable groove 404, the outer ends of the second movable plates 407 are fixedly connected with latches 408, the rear end of the first knob 405 is fixedly connected with a gear 406, and the opposite sides of the two sets of second movable plates 407 are provided with teeth meshing with the gear 406, and the inner wall of the air purifier 1 is provided with two sets of fixing holes 9. Figure 5 As shown, the structure is used to rotate the gear 406 by turning the first knob 405, and the gear 406 and the second movable plate 407 are meshed with each other to move the second movable plate 407 outward, insert the pin 408 into the fixing hole 9, and limit the first movable plate 401.

[0034] Furthermore, two groups of positioning grooves 7 are provided at the inner bottom of the air purifier 1, and two groups of protrusions are fixedly connected to the lower end of the housing 2, and the diameter of the protrusions is adapted to the positioning grooves 7. Figure 3 As shown, the structure is used to position the housing 2 through the positioning groove 7, which is convenient for guiding the installation of the housing 2 so that the housing 2 fits tightly with the air purifier 1.

[0035] Furthermore, the limiting plate 607 is located at the upper end of the filter plate 5, and a sealing ring is fixedly connected to the edge of the limiting plate 607, and the diameter of the limiting plate 607 is adapted to the third movable groove 601. Figure 6 As shown, the structure is used to enhance the sealing effect by providing a sealing ring on the outer edge of the limiting plate 607 to prevent dust from entering the third movable groove 601.

[0036] Working principle: When used, Figure 2 and Figure 4 As shown, first pull the clamping plate 302 to separate the lower end of the clamping plate 302 from the groove of the housing 2, so as to facilitate the removal of the housing 2. Figure 6 As shown, the second knob 602 is rotated to drive the second knob 602 to rotate, so that the slider 604 moves in a relative direction, and is hingedly connected to the limit plate 607 through the hinge rod 605, driving the limit plate 607 to move upward, so that the limit plate 607 is separated from the upper surface of the filter plate 5 and stored in the third movable groove 601, as shown in FIG. Figure 5As shown, the first knob 405 is turned to drive the gear 406 to rotate, and the gear 406 and the second movable plate 407 are meshed with each other, so that the second movable plate 407 moves inward, the latch 408 is disengaged from the fixing hole 9, the first movable plate 401 is moved, and then the first movable plate 401 is pulled to slide in the positioning groove 7 with the help of the roller 402, and the first movable plate 401 is pulled out of the air purifier 1 as a whole, and the five groups of filter plates 5 are taken out together, without the need to disassemble them one by one, thereby improving the disassembly efficiency, and the filter plate 5 in the placement plate 403 is cleaned or replaced. After the replacement is completed, the first movable plate 401 is moved into the air purifier 1 through the roller 402, and then the first knob 405 is turned. The opposite operation can be performed to limit the first movable plate 401, and then the second knob 602 is rotated in the opposite direction to make the limiting plate 607 fit against the surface of the filter plate 5. When installing the shell 2, it is only necessary to align the protrusion at the bottom of the shell 2 with the positioning groove 7 and push it into the air purifier 1. The lower end of the snap-in plate 302 is squeezed through the shell 2 to make the snap-in plate 302 move upward and contract, so that the spring 303 is deformed. When the edge of the shell 2 is completely in contact with the edge of the air purifier 1, under the rebound action of the spring 303, the lower end part of the snap-in plate 302 is inserted into the groove of the shell 2 to fix the shell 2. The above is the entire working principle of the utility model.
