DETAILED DESCRIPTION
[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0024] See also Figure 1-Figure 5 A water-proof automobile air filter intake duct includes an intake pipe 1, one end of the intake pipe 1 is fixedly connected to a drying filter box 2, both sides of the inner wall of the drying filter box 2 are slidably connected to first sliders 3, two first sliders 3 are respectively provided with first slide grooves 4, the inner walls of the drying filter box 2 are respectively rotatably connected to rotating shafts 6, one end of the two rotating shafts 6 are respectively fixedly connected to second sliders 7, and the two second sliders 7 cooperate with the two first slide grooves 4.
[0025] Second slide grooves 5 are provided on both sides of the inner wall of the drying filter box 2, and the two second slide grooves 5 are slidably connected to the two first sliders 3 respectively. Reset springs 8 are arranged in the two second slide grooves 5, and the two ends of the two reset springs 8 are fixedly connected to the drying filter box 2 and the first slider 3 respectively; a mounting plate 9 is fixedly connected between the two first sliders 3, and storage grooves 14 are provided on both sides of the mounting plate 9, wherein a filter plate 15 is arranged in one of the storage grooves 14, and a drying plate 16 is arranged in the other storage groove 14, and a residual groove 13 is provided at the bottom end of the inner wall of the drying filter box 2, and the residual groove 13 is located directly below the mounting plate 9.
[0026] The upper parts of both sides of the mounting plate 9 are rotatably connected to limit plates 17, and the filter plate 15 and the drying plate 16 are fixedly connected to the mounting plate 9 through the limit plates 17. A plurality of through holes 12 are provided on the mounting plate 9; a connecting block 10 is fixedly connected to the top of the mounting plate 9, and the connecting block 10 is slidably connected to the drying filter box 2. A sealing ring 11 is fixedly sleeved on the connecting block 10, and the thickness of the sealing ring 11 is greater than the thickness of the limit plates 17; an air inlet hole 18 is provided on the side of the drying filter box 2 close to the air inlet pipe 1, and a mounting base 20 is fixedly connected to the bottom end of the drying filter box 2, and a support sleeve 19 is fixedly connected to the mounting base 20, and the air inlet pipe 1 runs through the support sleeve 19, and a plurality of mounting ears 21 are fixedly connected to both sides of the mounting base 20.
