[0046] like Figure 8As shown, further, the sixth sliding mechanism includes four slide grooves 4011, and the four slide grooves 4011 are respectively opened in the inner cavity of the installation slot 401, and the four slide grooves 4011 are symmetrical to each other, and the inner cavities of the four slide grooves 4011 are all slidably installed with sliders 4012, and the four sliders 4012 are symmetrical to each other, and the inner cavities of the four slide grooves 4011 are all provided with return springs 4013, and the two ends of each return spring 4013 are respectively fixedly connected to the two opposite side walls of the slide groove 4011 and the slider 4012.

In this configuration, the installation position and components of the conical plate 4015 are determined.

[0048] like Figure 7 As shown, further, four second slide rails 2051 that are symmetrical to each other are arranged at the bottom of the inner cavity of the sealing shell 1024, and sealing plates 205 are installed above each two of the four second slide rails 2051. Inclined blocks 2052 are arranged at opposite ends of the two sealing plates 205. The two inclined blocks 2052 are symmetrical to each other, and inclined grooves 2053 are provided at the bottom of the two inclined blocks 2052. Limiting sliders 2054 are slidably installed in the inner cavities of the two inclined grooves 2053. The two limiting sliders 2054 are symmetrical to each other, and moving rods 2042 are movably installed at the bottom of the two limiting sliders 2054. In this arrangement, it is ensured that when the moving rod 2042 moves up and down, it will be able to push the tilting block 2052, which will drive the tilting block 2052 with the assistance of the tilting groove 2053 and the limiting slider 2054 to drive the sealing plate 205 to move horizontally with the assistance of the second slide rail 2051. When the sealing plate 205 moves, it will be able to seal the air intake pipe 1023, so that the gas can only flow out from the rectangular groove 1026 at the air intake pipe 1023 at this time, thereby entering the purifier body 101, and then discharged from the side filter hole 1012.

[0049] The implementation principle of a vehicle-mounted air purifier of this embodiment is as follows:

[0050] First, the staff starts the servo motor 201. When the servo motor 201 is running, it can drive the threaded rod 2011 to rotate, and when the threaded sleeve 2012 is assisted by the fixing plate 2013 and the guide rod 2014, it can drive the air intake pipe 1023 to rotate. When the air intake pipe 1023 rotates, it can drive the circular sleeve plate 202 to rotate through the first slide rail 1025.

[0051] Because the bottom of the circular sleeve plate 202 is provided with a second sliding mechanism (because the second sliding mechanism is the first circular slide groove 2021 and the first guide slider 2022), and the bottom of the first guide slider 2022 is fixedly connected with a connecting rod 2023, and the connecting rod 2023 movably penetrates the circular sealing plate 1021, and the circular sealing plate 1021 is fixedly connected to the fixed plate 2013, when the fixed plate 2013 moves upward, it can push the circular sleeve plate 202 to rotate and move vertically upward;

[0052] When the circular sleeve plate 202 moves upward, the movable rod 2032 can be driven to move through the third sliding mechanism (the third sliding mechanism is the second circular sliding groove 203 and the second guide slider 2031). When the movable rod 2032 moves, the movable plate 301 can be pulled to move horizontally with the assistance of the first sliding mechanism (wherein the first sliding mechanism includes the movable sliding groove 103 and the movable slider 1031).

[0053] When the movable plate 301 moves, it will be able to drive the guide rod 3011 to move. When the guide rod 3011 moves, the guide rod 3011 will be able to rotate slightly with the assistance of the fifth sliding mechanism (the inclined groove 3021 and the mounting slide block 3022); thereby, the guide rod 3011 can be rotated to leave the side filter hole 1012;

[0054] When the circular socket plate 202 moves upward to a certain position, the conical plate 4015 provided in the inner cavity of the circular socket plate 202 will be able to move in the air intake duct 1023 until the conical plate 4015 moves to the rectangular notch 1026. At this time, the conical plate 4015 will be able to move horizontally with the assistance of the slide groove 4011 and the slider 4012 in the sixth slider. Therefore, with the assistance of the return spring 4013, the moving block 4014 can be moved with the assistance of the slider 4012, so that the conical plate 4015 can be inserted into the rectangular notch 1026 to push the flip plate 402 to open.

[0055] When the circular socket plate 202 moves upward and rotates, it will be able to drive the moving rod 2042 to move vertically up and down in the inner cavity of the circular sealing plate 1021 with the assistance of the third circular slide groove 204 and the third guide slider 2041 in the fourth sliding mechanism. When the moving rod 2042 moves up and down, it will be able to push the tilting block 2052 to drive the tilting block 2052 with the assistance of the tilting slide groove 2053 and the limit slider 2054 to drive the sealing plate 205 to move horizontally with the assistance of the second slide rail 2051. When the sealing plate 205 moves, it will be able to seal the air intake pipe 1023, so that the gas can only flow out from the rectangular notch 1026 at the air intake pipe 1023 at this time, thereby entering the purifier body 101, and then discharged from the side filter hole 1012.
