On the upper surface inside the exhaust hood, there are flat air outlets symmetrically rotatably connected through a rotating shaft. There is an air outlet hose fixedly connected and communicating between the flat air outlet and the exhaust duct.

[0009] On the left side of the fresh air box and below the moving seat, there is a double-shaft motor fixedly connected. The top end of the output end of the double-shaft motor penetrates into the inside of the moving seat and is fixedly connected with a bevel gear two, and the bevel gear two is meshed and connected with the two bevel gears one.

[0010] Furthermore, on the lower right side of the fresh air box, there is an air inlet outer connecting pipe integrally formed.

[0011] Furthermore, a first filter screen is snap-fitted and installed below the inside of the fresh air box, and a second filter screen is snap-fitted and installed above the first filter screen inside the fresh air box.

[0012] Furthermore, on the outer side wall of the air outlet hose and inside the exhaust cavity, there is an abutting ring fixedly connected. A second spring is sleeved on the outer side wall of the air outlet hose, and both ends of the second spring are fixedly connected with the opposite sides of the abutting ring and the exhaust cavity respectively.

[0013] Furthermore, on the left side of the fresh air box and below the double-shaft motor, there is an inflation box fixedly connected. A piston plate is slidably connected inside the inflation box, and a vertical rod is fixedly connected to the upper surface of the piston plate.

[0014] Furthermore, the bottom end of the output shaft of the double-shaft motor is fixedly connected with a cylinder, and an inclined annular groove is integrally formed on the outer side wall of the cylinder. A connecting column is fixedly connected to the outer side wall of the vertical rod inside the inclined annular groove.

[0015] Furthermore, the bottom end of the flat air outlet is fixedly connected with a shaft column. The bottom end of the shaft column penetrates below the exhaust hood, and an eccentric disc is fixedly connected to the outer side wall. The lower surface of the eccentric disc is rotatably connected with a traction rod through a rotating shaft. The front surfaces of the upper surfaces of the two traction rods are rotatably connected together through a rotating shaft with a fixed block. The lower surface of the exhaust hood is fixedly connected with an inflatable telescopic tube, and the front end of the inflatable telescopic tube is fixedly connected with the rear surface of the fixed block. A ventilation pipe is fixedly connected and communicating between the inflation box and the inflatable telescopic tube.

[0016] Further, a sliding box is fixedly connected to the front surface of the fixed block. A pressure-receiving bar is slidably connected inside the sliding box. A first spring is fixedly connected between the pressure-receiving bar and the sliding box. A push rod is fixedly connected to the front surface of the pressure-receiving bar.

Through the transmission of the first bevel gear and the second bevel gear, the reciprocating lead screw is driven to rotate, and then the moving plate is driven to slide inside the moving seat, controlling the movement of the exhaust hood to increase the exhaust air range, making the fresh air exhaust range more extensive;

[0019] After the fresh air discharged from the exhaust pipe is discharged into the flat air outlet through the air outlet hose, it is discharged through the exhaust hood. The flat air outlet can swing back and forth, thereby increasing the air outlet range. At the same time, the guide vane can also swing up and down to further increase the exhaust range;

[0020] When the exhaust hood moves to the edge of the moving seat, it will pull the air outlet hose out of the exhaust cavity. At this time, the second spring will be compressed. When the exhaust hood moves to the first bevel gear, the second spring will stretch and pull the air outlet hose into the exhaust cavity. This method can avoid the problem that when the exhaust hood moves and pulls the air outlet hose out of the exhaust cavity, it cannot automatically contract and is easily wound around the outer wall of the reciprocating lead screw;

[0021] Using the wedge-shaped extrusion block to squeeze the pressure-receiving bar can make the push rod shake slightly left and right. Therefore, when the guide vane swings up and down for guiding, it can further shake, changing the air outlet flow direction and making the air inlet range more extensive.

[0030] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment: As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a fresh air system integrating dust removal and purification is provided, including a fresh air box 1. An exhaust cavity 2 is integrally formed inside the fresh air box 1. A plurality of fans 3 are embedded and installed on the right side of the exhaust cavity 2. The output end of the fan 3 is fixedly connected with an exhaust pipe 4 inside the exhaust cavity 2;

[0032] The left side of the fresh air box 1 is fixedly connected with a moving seat 5. The front inner surface and the rear inner surface of the moving seat 5 are both rotatably connected with a reciprocating lead screw 6 through a rotating shaft. The relative ends of the two reciprocating lead screws 6 are both fixedly connected with a first bevel gear 7. The outer side wall of the reciprocating lead screw 6 is threadedly connected with a moving plate 8. The left side of the moving plate 8 is fixedly connected with an exhaust hood 9;

[0033] The right side below the fresh air box 1 is integrally formed with an inlet air external connection pipe 16;

[0034] A first filter screen 17 is snap-fitted and installed below the interior of the fresh air box 1, and a second filter screen 18 is snap-fitted and installed above the first filter screen 17 inside the fresh air box 1;

[0035] A double-shaft motor 14 is fixedly connected below the left side of the fresh air box 1 and below the moving seat 5. The top end of the output shaft of the double-shaft motor 14 penetrates into the interior of the moving seat 5 and is fixedly connected with a second bevel gear 15, and the second bevel gear 15 is meshed with two first bevel gears 7;

[0036] When the device is in use, the outdoor ventilation area is connected through the air inlet external connecting pipe 16, and then multiple fans 3 are started to intake air. After the outside air is filtered by the first filter screen 17 and the second filter screen 18, it is discharged through the exhaust hood 9. At the same time, the double-shaft motor 14 can be started. Through the transmission of the first bevel gear 7 and the second bevel gear 15, the reciprocating lead screw 6 is driven to rotate, and then the moving plate 8 is driven to slide inside the moving seat 5, controlling the movement of the exhaust hood 9, increasing the exhaust air range, and making the fresh air exhaust range wider;

[0037] A plurality of guide vanes 10 are rotatably connected to the left side inside the exhaust hood 9 through a rotating shaft. A plurality of connecting pieces 11 are arranged on both sides of the plurality of guide vanes 10 on the front surface of the exhaust hood 9. The opposite side of the connecting piece 11 and the guide vane 10 are rotatably connected through a rotating shaft. The upper surface inside the exhaust hood 9 is symmetrically rotatably connected with a flat air outlet 12 through a rotating shaft, and an air outlet hose 13 is fixedly connected and communicated between the flat air outlet 12 and the exhaust duct 4;

[0038] After the fresh air discharged from the exhaust duct 4 is discharged into the flat air outlet 12 through the air outlet hose 13, it is discharged through the exhaust hood 9. The flat air outlet 12 can swing back and forth, so as to increase the air outlet range. At the same time, the guide vanes 10 can also swing up and down to further increase the exhaust range;

[0039] A retaining ring 41 is fixedly connected to the outer side wall of the air outlet hose 13 inside the exhaust cavity 2. A second spring 29 is sleeved on the outer side wall of the air outlet hose 13, and both ends of the second spring 29 are fixedly connected to the opposite sides of the retaining ring 41 and the exhaust cavity 2 respectively;

[0040] When the exhaust hood 9 moves to the edge of the moving seat 5, it will pull the air outlet hose 13 to extend out of the exhaust cavity 2. At this time, the second spring 29 will be compressed. When the exhaust hood 9 moves to the position of the first bevel gear 7, the second spring 29 will stretch and pull the air outlet hose 13 into the exhaust cavity 2. This method can avoid the problem that when the exhaust hood 9 moves, after pulling the air outlet hose 13 out of the exhaust cavity 2, it cannot automatically contract and is easily wound around the outer side wall of the reciprocating lead screw 6.

[0041] Such as Figure 5 、 Figure 6 and Figure 7As shown in the figure, an inflation box 19 is fixedly connected below the left side of the fresh air box 1 and under the double-shaft motor 14. A piston plate 20 is slidably connected inside the inflation box 19, and a vertical rod 21 is fixedly connected to the upper surface of the piston plate 20;

[0042] The bottom end of the output shaft of the double-shaft motor 14 is fixedly connected with a cylinder 22. An inclined annular groove 23 is integrally formed on the outer side wall of the cylinder 22, and a connecting column 24 is fixedly connected to the outer side wall of the vertical rod 21 inside the inclined annular groove 23;

[0043] The bottom end of the flat air outlet 12 is fixedly connected with a shaft column 25. The bottom end of the shaft column 25 penetrates below the exhaust hood 9, and an eccentric disc 26 is fixedly connected to the outer side wall. The lower surface of the eccentric disc 26 is rotatably connected with a traction rod 27 through a rotating shaft. The front surfaces of the two traction rods 27 are rotatably connected with a fixed block 28 through a rotating shaft in common. The lower surface of the exhaust hood 9 is fixedly connected with an inflatable telescopic tube 30. The front end of the inflatable telescopic tube 30 is fixedly connected with the rear surface of the fixed block 28. A gas exchange pipe 31 is fixedly connected and communicated between the inflation box 19 and the inflatable telescopic tube 30;

[0044] When the double-shaft motor 14 is started, through the arranged connecting column 24, vertical rod 21 and inclined annular groove 23, the piston plate 20 can slide up and down repeatedly inside the inflation box 19, so that the inflation box 19 can be repeatedly inflated and deflated into the inflatable telescopic tube 30 through the gas exchange pipe 31, controlling the fixed block 28 to move left and right repeatedly. Thus, under the pulling of the traction rod 27, the eccentric disc 26 is driven to rotate reciprocally in a small range, and then the flat air outlet 12 can be driven to swing back and forth, initially increasing the front and rear air outlet range;

[0045] The front surface of the fixed block 28 is fixedly connected with a sliding box 32. A pressure-receiving strip 33 is slidably connected inside the sliding box 32. A first spring 34 is fixedly connected between the pressure-receiving strip 33 and the sliding box 32. The front surface of the pressure-receiving strip 33 is fixedly connected with a push rod 35. The front end of the push rod 35 penetrates in front of the sliding box 32 and is fixedly connected with a first concave part 36. The inner side of the first concave part 36 is rotatably connected with a movable block 37 through a rotating shaft. The top end of the movable block 37 is rotatably connected with a second concave part 38 through a rotating shaft. The top of the second concave part 38 is fixedly connected with the lower surface of the guide vane 10 located below the inner side of the exhaust hood 9;

[0046] On the lower surfaces of the two exhaust hoods 9 and at the opposite ends of the two pressure-receiving strips 33, a blocking strip 39 is fixedly connected. A plurality of wedge-shaped extrusion blocks 40 are fixedly connected to the side of the blocking strip 39 close to the pressure-receiving strip 33;

[0047] When the fixed block 28 moves left and right repeatedly, it will drive the push rod 35 to move left and right repeatedly. Then, under the linkage of the first concave part 36, the movable block 37 and the second concave part 38, and by using the fact that a plurality of guide vanes 10 are linked through a plurality of connecting pieces 11, the plurality of guide vanes 10 can be controlled to swing up and down, increasing the up and down air outlet range;

[0048] During the left - right reciprocating movement of the push rod 35, the wedge - shaped extrusion block 40 is used to squeeze the pressure - receiving strip 33, which can cause the push rod 35 to vibrate slightly left and right. Thus, when the flow - guiding piece 10 swings up and down for guiding the flow, it can further vibrate, change the air outlet flow direction, and make the air inlet range wider.

[0049] The above - described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
