[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0025] See also Figure 1-4 As shown, this embodiment provides a device for blowing away impurities inside a Teflon air duct, comprising a mounting frame 1, an electric telescopic rod is mounted on the top of the mounting frame 1, a clamping plate 2 adapted to the outer peripheral wall of the Teflon air duct is fixedly mounted on the output end of the electric telescopic rod, a placement frame 3 adapted to the outer peripheral wall of the Teflon air duct is fixedly mounted on the mounting frame 1 at a position adjacent to the bottom of the clamping plate 2, a fan 4 and a closing mechanism 5 are sequentially arranged on the left side of the placement frame 3 from left to right, a flexible wind cover 6 is mounted between the fan 4 and the closing mechanism 5, a scraping brush mechanism 7 is mounted on the right side of the fan 4, and the clamping plate 2 is driven to move up and down by the electric telescopic rod, so as to adjust the distance between the clamping plate 2 and the placement frame 3 to adapt to Teflon air ducts of different sizes;
[0026] The fan 4 includes a fixed box 41 fixedly connected to the mounting frame 1, a fan blade 42 is rotatably mounted in the fixed box 41, a driving motor for driving the fan blade 42 to rotate is mounted on the fixed box 41, an exhaust mesh plate 43 is fixedly mounted on one side of the fixed box 41 adjacent to the flexible wind hood 6, an air inlet (not shown in the figure) for promoting the air flow in the fixed box 41 is opened on the other side of the fixed box 41, the outer peripheral wall of the exhaust mesh plate 43 is fixedly connected to the port on one side of the flexible wind hood 6, and the rotating fan blade 42 blows the clean air in the direction of the exhaust mesh plate 43, and blows it into the flexible wind hood 6 through the exhaust mesh plate 43;
[0027] The scraping and brushing mechanism 7 includes an incomplete gear 71 that is rotatably connected to the exhaust mesh plate 43, and the incomplete gear 71 is driven by a pulley with the rotating shaft of the fan blade 42. A rotating rod 72 that is rotatably connected to the mounting frame 1 is provided on the right side of the fan 4. A driven gear 73 that meshes with the incomplete gear 71 is fixedly installed on one end of the rotating rod 72 that is adjacent to the incomplete gear 71. A support frame 74 is fixedly installed on the outer peripheral wall of the rotating rod 72. A pair of symmetrical sliding rods 75 are slidably installed on the top and bottom of the support frame 74. An extrusion plate 76 is fixedly installed on one end of the pair of sliding rods 75. A brush 77 is fixedly installed on the side of the extrusion plate 76 away from the sliding rod 75. A plurality of springs 78 are fixedly installed between the extrusion plate 76 and the support frame 74.
[0028] By squeezing the two squeezing plates 76, the slide bar 75 is driven to slide on the support frame 74, and the slide bar 75 is made to cooperate with the support frame 74 to compress the multiple springs 78 at the same time, so as to reduce the distance between the two brushes 77. Then, the Teflon air duct is sleeved on the outside of the scraping and brushing mechanism 7, and the pressure on the two squeezing plates 76 is released. The compressed multiple springs 78 rebound and drive the brushes 77 to fit the inner wall of the Teflon air duct through the squeezing plates 76, so as to adapt to the Teflon branch pipes with different sizes of inner peripheral walls.
[0029] When the incomplete gear 71 rotates synchronously with the fan blade 42 through the pulley, the rotating incomplete gear 71 drives the rotating rod 72 to rotate intermittently through the driven gear 73 meshing therewith, so that the support frame 74 drives the brush 77 attached to the inner wall of the Teflon air duct to scrape the inner wall of the Teflon air duct to scrape off the impurities tightly attached to the inner wall;

[0031] Rotating the winding rod 53 in the clockwise direction will tighten the winding rope passed through the port of the flexible wind cover 6, and vice versa will loosen the winding rope. The size of the port of the flexible wind cover 6 can be adjusted by the winding rope that can be loosened or tightened to adapt to the ports of Teflon air ducts of different sizes and seal them, so that the wind blown by the fan 4 can be completely blown into the interior of the Teflon air duct, reducing the waste of wind energy.
[0032] When the utility model is in use, firstly, the Teflon air duct is sleeved on the scraping and brushing mechanism 7, and the port on one side of the Teflon air duct is inserted into the flexible wind cover 6, then the Teflon air duct is placed on the top of the placement frame 3, the clamping plate 2 is moved downward to fix and clamp the Teflon air duct, and then the reeling rod 53 is rotated to adjust the tightness of the reeling rope until the port on one side of the flexible wind cover 6 is completely sealed on the outer peripheral wall of the Teflon air duct port, and finally the fan blades 42 are rotated to blow clean air completely into the Teflon air duct through the flexible wind cover 6 sealed between the fan 4 and the Teflon air duct. While the fan blades 42 are rotating, the scraping and brushing mechanism 7 intermittently scrapes and brushes the inner wall of the Teflon to scrape off impurities tightly adsorbed on the inner wall of the Teflon, and the fallen impurities are blown out from the other port of the Teflon air duct in conjunction with the flowing air.
