[0023] The specific arrangement and function of the filtering device 4 and the limiting device 5 will be described in detail below.

[0024] In the present embodiment: a filter device 4 is provided on the outer wall surface of the air inlet pipe body 1, and the filter device 4 includes a strip plate 401, which is fixedly installed on the outer wall surface of the air inlet pipe body 1, and a slide groove 402 is provided on the surface of the strip plate 401, and a slide plate 403 is slidably connected inside the slide groove 402, and two vertical plates 404 are fixedly installed on the surface of one end of the slide groove 403 away from the slide groove 402, and a rotating shaft 405 is rotatably connected between the two vertical plates 404, and a motor 406 is fixedly installed on the surface of one of the vertical plates 404, and the output end of the motor 406 is fixedly connected to the rotating shaft 405.

[0025] In this embodiment, the motor 406 is provided to drive the rotating shaft 405 to rotate.

[0026] Specifically, a rotating plate 407 is fixedly mounted on the outer wall surface of the rotating shaft 405 , a connecting rod 408 is fixedly mounted on the side of the rotating plate 407 , and one end of the connecting rod 408 away from the rotating plate 407 is located inside the mounting tube 6 .

[0027] In this embodiment, the connection rod 408 is provided to drive the filter screen 3 to rotate.

[0028] Specifically, a long groove 409 is provided on the side of the strip plate 401, and a displacement plate 410 is slidably connected inside the long groove 409. One end of the displacement plate 410 away from the long groove 409 is fixedly connected to the slide plate 403. Bolts 411 are threadedly connected to the surface of the displacement plate 410, and a plurality of threaded holes 412 are evenly provided on the side of the strip plate 401. The arrangement of the displacement plate 410 has the effect of driving the slide plate 403 to move inside the slide groove 402, and the arrangement of the bolts 411 and the threaded holes 412 has the effect of limiting the position of the displacement plate 410 inside the long groove 409.

[0029] In this embodiment: a limiting device 5 is provided on the outer wall surface of the mounting tube 6, the limiting device 5 includes a sliding rod 51, the sliding rod 51 is fixedly mounted on the outer wall surface of the mounting tube 6, a movable plate 52 is slidably connected to the surface of the sliding rod 51, a limiting rod 53 is fixedly mounted on the surface of the movable plate 52, and a limiting hole 54 is provided on the outer wall surface of the connecting rod 408. When the filter screen 3 needs to be maintained and replaced after being used for a long time, the sliding plate 58 is first slid to make the sliding plate 58 move inside the groove 57. The movement of the sliding plate 58 inside the groove 57 drives the moving plate 52 to move on the surface of the sliding rod 51. The movement of the moving plate 52 on the surface of the sliding rod 51 will squeeze the spring 56, so that the spring 56 is compressed. At the same time, the movement of the moving plate 52 on the surface of the sliding rod 51 also drives the limiting rod 53 to move. The limiting rod 53 moves to move itself out of the limiting hole 54. The limiting rod 53 and the limiting hole 54 are separated so that the connecting rod 408 loses its limit in the installation cylinder 6. At this time, the filter screen 3 can be pulled, and the filter movement drives the installation cylinder 6 to move. The installation cylinder 6 moves to make the connecting rod 408 move out of its interior, completing the disassembly operation of the filter screen 3. Through the cooperation of the above structure, the purpose of disassembling the filter screen 3 is achieved, so that the filter screen 3 can be replaced and cleaned in time when it is blocked, so as to avoid the filter screen 3 from being blocked and affecting its filtering effect.

[0030] Specifically, an extension plate 55 is fixedly mounted on the surface of one end of the slide rod 51 away from the mounting tube 6 , and a spring 56 is fixedly mounted between the extension plate 55 and the moving plate 52 .

[0031] In this embodiment, the setting of the spring 56 has the effect of limiting the position of the moving plate 52 on the surface of the slide rod 51 .

[0032] Specifically, a groove 57 is formed on the surface of the extension plate 55 , and a sliding plate 58 is slidably connected inside the groove 57 . One end of the sliding plate 58 away from the groove 57 is fixedly connected to the moving plate 52 .

[0033] In this embodiment, the setting of the sliding plate 58 has the effect of driving the moving plate 52 to move on the surface of the sliding rod 51 .

[0034] Working principle: By setting the filter device 4, when the device is in use, firstly connect one end of the intake pipe with the mounting plate 2 and the air inlet of the automobile air filter. When the automobile is not in use and the engine is turned off, firstly start the motor 406. The motor 406 starts to drive the rotating shaft 405 to rotate. The rotating shaft 405 rotates and drives the rotating plate 407 to rotate. The rotating plate 407 rotates and drives the connecting rod 408 to rotate. The connecting rod 408 rotates and drives the filter 3 to rotate. When the rotating position of the filter 3 and the port of the intake pipe body 1 are at the same horizontal line, turn off the motor 406, and then loosen the bolt 411, screw the bolt 411 out from the inside of the threaded hole 412, and separate the bolt 411 and the threaded hole 412. The displacement plate 410 loses its limit inside the long groove 409, and the displacement plate 410 can be moved at this time. The movement of the displacement plate 410 drives the slide plate 403 to move inside the slide groove 402. The movement of the slide plate 403 inside the slide groove 402 drives the connecting rod 408 to move. The movement of the connecting rod 408 drives the filter 3 to move. When the filter 3 moves to the inside of the intake pipe, the bolt 411 is screwed into the corresponding threaded hole 412 again to fix the position of the displacement plate 410 inside the long groove 409 at this time. Through the cooperation of the above-mentioned structure, the filter 3 can filter out the dust entering the inside of the intake pipe, reduce the amount of dust sucked into the air filter, and improve the service life of the air filter. When the filter screen 3 needs to be maintained and replaced after being used for a long time, the sliding plate 58 is first slid to make the sliding plate 58 move inside the groove 57. The movement of the sliding plate 58 inside the groove 57 drives the moving plate 52 to move on the surface of the sliding rod 51. The movement of the moving plate 52 on the surface of the sliding rod 51 will squeeze the spring 56, so that the spring 56 is compressed. At the same time, the movement of the moving plate 52 on the surface of the sliding rod 51 also drives the limiting rod 53 to move. The limiting rod 53 moves to move itself out of the limiting hole 54. The limiting rod 53 and the limiting hole 54 are separated so that the connecting rod 408 loses its limit in the installation cylinder 6. At this time, the filter screen 3 can be pulled, and the filter movement drives the installation cylinder 6 to move. The installation cylinder 6 moves to make the connecting rod 408 move out of its interior, completing the disassembly operation of the filter screen 3. Through the cooperation of the above structure, the purpose of disassembling the filter screen 3 is achieved, so that the filter screen 3 can be replaced and cleaned in time when it is blocked, so as to avoid the filter screen 3 from being blocked and affecting its filtering effect.
