Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0021] Please refer to Figures 1-5 As shown in the figure, a new drain pipe structure of a blower, including first drain pipe 1, second drain pipe 2 and third drain pipe 3, second drain pipe 2 is located between first drain pipe 1 and third drain pipe 3, and the two ends of second drain pipe 2 are respectively connected with first drain pipe 1 and third drain pipe 3, the upper surface of first drain pipe 1 is fixed with flange, and first drain pipe 1 is communicated with the drain port of blower through flange, the lower surface of first drain pipe 1 is fixed with fixed plate 4, the left and right sides of fixed plate 4 are bolted with mounting bracket 5, and the surface of mounting bracket 5 is provided with screw hole for installation, the right side of the top of fixed plate 4 is fixed with box body 6, and the inside of box body 6 is fixed with electric push rod 7, the left end of the output shaft of electric push rod 7 penetrates to the outside of box body 6 and is fixed with moving bracket 8, the front and rear sides of moving bracket 8 are fixed with connecting plate 9, the lower side of connecting plate 9 is rotatably connected with first connecting shaft 10, the surface of first connecting shaft 10 is fixed with movable plate 11, the surface of the front and rear sides of third drain pipe 3 is rotatably connected with second connecting shaft 12.
[0022] The movable plate 11 is inclined as a whole, and the second connecting shaft 12 penetrates through the movable plate 11 and is fixedly connected with the movable plate 11. The front and rear sides of the fixed plate 4 are both provided with a limiting groove 13, and the left side of the inner wall of the limiting groove 13 is slidably connected with a limiting block 14. One end of the first connecting shaft 10 is rotatably connected with the surface of the limiting block 14. When the moving frame 8 drives the connecting plate 9 to move to the right side, the first connecting shaft 10 pushes the movable plate 11 to move to the right side, so that the first connecting shaft 10 and the second connecting shaft 12 are rotated, and the second drain pipe 2 is deformed, and the third drain pipe 3 is turned to the right side, so as to drain the condensed water in the air blower. The limiting groove 13 and the limiting block 14 can guide the first connecting shaft 10 and increase the stability of the first connecting shaft 10 when moving left and right.
[0023] The second drain pipe 2 is a stainless steel corrugated pipe, the first drain pipe 1 and the third drain pipe 3 are both made of PVC plastic, and the surfaces of the inner walls of the first drain pipe 1, the second drain pipe 2 and the third drain pipe 3 are all coated with a polytetrafluoroethylene coating. When the third drain pipe 3 is pushed, the second drain pipe 2 can be deformed to adjust the whole drain pipe structure, so as to drain the waste water. The pipe bending condition is optimized during the drainage, the impurities are prevented from accumulating in the drain pipe, the impurities are conveniently drained, and the hydrophobic coating added to the inner wall of the pipe can effectively reduce the dirt adhesion.
[0024] The surface of the left side of the moving frame 8 is bonded with a protective pad 15 made of wear-resistant rubber. When the moving frame 8 moves to the left side, the protective pad 15 directly contacts the surface of the first drain pipe 1, so as to protect the first drain pipe 1 from being damaged by the moving frame 8.
[0025] The right side of the bottom of the fixed plate 4 is provided with a receiving groove 18, and the third drain pipe 3 is slidably connected with the inner wall of the receiving groove 18. When the drain pipe structure does not drain, the movable plate 11 pulls the third drain pipe 3 into the receiving groove 18, so as to seal the drainage of the third drain pipe 3 by the receiving groove 18, and prevent the outside sewage and impurities from entering.
[0026] The front and rear sides of the right side of the moving frame 8 are both fixedly provided with a fixed frame 16, and the lower side of the fixed frame 16 is fixedly provided with a cleaning brush 17. The bottom of the cleaning brush 17 is attached to the surface of the fixed plate 4.
