[0025] In a preferred embodiment, a limiting frame 9 is fixedly mounted on the side of the base 2. A spring 11 is fixedly connected to the side of the inner wall of the limiting frame 9, and a protruding plate 12 is fixedly connected to the end of the spring 11 away from the inner wall of the limiting frame 9. The protruding teeth on the side of the protruding plate 12 mesh with the protruding teeth on the outer edge of the adjusting gear 8. An adjusting rod 10 is fixedly mounted on the side of the protruding plate 12, and the side of the adjusting rod 10 is slidably connected to the inner wall of the limiting frame 9. Through the cooperation of the spring 11 and the protruding plate 12, the spring 11 pushes the protruding plate 12 to move in the inner wall of the limiting frame 9, thereby using the protruding teeth on the side of the protruding plate 12 to mesh with the protruding teeth on the outer edge of the adjusting gear 8, thereby ensuring that the adjusting gear 8 is limited. With the addition of the adjusting rod 10, the position of the protruding plate 12 can be easily adjusted by the adjusting rod 10.

[0026] In a preferred embodiment, a side frame 16 is fixedly mounted on the side of the base 2, and a second spring 26 is fixedly connected to the side of the inner wall of the side frame 16. The end of the second spring 26 away from the inner wall of the side frame 16 is fixedly connected to the side of the U-shaped plate 17. Through the cooperation of the second spring 26 and the side frame 16, the second spring 26 pushes the U-shaped plate 17 to move in the inner wall of the side frame 16, and assists the side of the U-shaped plate 17 to close the inlet 22 and the outlet 23.

[0027] In a preferred embodiment, a groove 21 is provided on the side of the side frame 16, and a slide rod 20 is rotatably connected to the side of the U-shaped plate 17. The shape and size of the outer edge of the slide rod 20 are adapted to the shape and size of the inner wall of the groove 21. A pull rod 19 is fixedly mounted on the side of the slide rod 20. Through the cooperation of the groove 21 and the slide rod 20, the side of the slide rod 20 moves through the inner wall of the groove 21 to the side of the side frame 16, and then the pull rod 19 is rotated. The pull rod 19 drives the slide rod 20 to rotate, thereby assisting the side of the slide rod 20 to overlap and limit the side of the side frame 16.

[0028] In a preferred embodiment, an evaporator 24 is fixedly mounted on the inner wall of the outer casing 1, and a fan 25 is fixedly mounted on the top of the outer casing 1. An inlet 22 is opened on the inner wall of the base 2 near the bottom, and an outlet 23 is provided at the bottom of the inlet 22. Through the cooperation of the outlet 23 and the inlet 22, the inner walls of the outlet 23 and the inlet 22 are connected with the inner wall of the connecting groove 18, thereby assisting the inlet 22 and the outlet 23 to communicate with the outside. Furthermore, the side of the U-shaped plate 17 is connected with the inner wall of the outlet 23 and the inner wall of the inlet 22, thereby assisting the outlet 23 and the inlet 22 to be sealed.

[0029] Working principle: When the device is in use, the side of the protective net 3 is limited to the inner wall of the outer box 1. Then, the adjusting rod 10 is moved away from the adjusting gear 8. The adjusting rod 10 drives the convex teeth of the convex plate 12 to separate from the convex teeth on the outer edge of the adjusting gear 8. The tension spring 5 drives the rotating gear 4 to rotate. The rotating gear 4 drives the top outer edge of the arc plate 6 to limit the bottom inner wall of the protective net 3 through the toothed plate 7. Then, the spring 11 pushes the convex teeth of the convex plate 12 to limit the outer edge of the adjusting gear 8. The auxiliary block 15 drives the triangular baffle 14 to move. The triangular baffle 14 assists in further limiting the protective net 3. The pull rod 19 drives the U-shaped plate 17 to move. The outer edge of the sliding rod 20 passes through the inner wall of the sliding groove 21. The pull rod 19 is rotated, so that the side of the sliding rod 20 is limited to the side of the side frame 16 by the pull rod 19. This assists in connecting the inner wall of the connecting groove 18 with the inner wall of the inlet 22 and the inner wall of the outlet 23, thus facilitating the flow between the outside and the inside.
