Both ends of the rotating rod 21 are fixedly connected to the inner surface of the groove of the waist-mounted fan body 1. A connecting block 22 is rotatably connected to the arc surface of the rotating rod 21. The surface of the connecting block 22 is fixedly connected to the flip cover 3. A buckle 24 is fixedly connected to the lower surface of the flip cover 3. A card slot is formed on the upper surface of the waist-mounted fan body 1. The buckle 24 is slidably connected to the inner surface of the card slot of the waist-mounted fan body 1. A sliding plate 26 is slidably connected in the card slot of the waist-mounted fan body 1. The sliding plate 26 is slidably connected to the lower surface of the buckle 24. A first sliding rod 27 is slidably connected in the sliding plate 26. One end of the first sliding rod 27 is fixedly connected to a sliding cap 28. The end of the first sliding rod 27 away from the sliding cap 28 is fixedly connected to the waist-mounted fan body 1. Two torsion springs 23 are sleeved on the arc surface of the rotating rod 21. Both ends of the torsion springs 23 are respectively fixedly connected to the groove of the waist-mounted fan body 1 and the connecting block 22. By setting the torsion springs 23, when the limit of the buckle 24 is released, the flip cover 3 achieves the effect of automatic gear rebound, improving the convenience of the device. A spring 29 is sleeved on the arc surface of the first sliding rod 27. Both ends of the spring 29 are respectively fixedly connected to the sliding plate 26 and the waist-mounted fan body 1. By setting the spring 29, the effect of automatic gear rebound of the slider is achieved, avoiding the situation where the slider cannot bounce back, and improving the convenience of the device. A sealing ring 25 is fixedly connected to the upper surface of the waist-mounted fan body 1. The upper surface of the sealing ring 25 abuts against the flip cover 3. By setting the sealing ring 25, the effect of preventing the wind blown by the fan from dispersing everywhere is achieved, improving the air-cooling effect of the waist-mounted fan body 1.

[0033] Referring to Figure 1 and Figure 2 As shown in the figure, specifically, the protection device 4 includes a first protective sleeve 41. The first protective sleeve 41 is slidably connected to the surface of the waist-mounted fan body 1. One side of the first protective sleeve 41 is fixedly connected to a Y-shaped frame 42. A number of adjustment holes are formed on both sides of the Y-shaped frame 42. A second protective sleeve 43 is slidably connected to the surface of the Y-shaped frame 42. A second sliding rod 44 is slidably connected in the second protective sleeve 43. The arc surface of the second sliding rod 44 is slidably connected to the inner surface of the adjustment hole of the Y-shaped frame 42. The size of the second sliding rod 44 is adapted to the size of the adjustment hole. Threads are formed at both ends of the second sliding rod 44. Nuts 45 are threadedly connected to both ends of the sliding rod. The nuts 45 abut against the side wall of the second protective sleeve 43. By setting the nuts 45, the effect of fixing the second sliding rod 44 is achieved, avoiding the situation where the second sliding rod 44 accidentally slides off, resulting in the separation of the protection device 4 from the waist-mounted fan body 1, and improving the practicality of the device.

By setting the nut 45, the effect of fixing the second slide rod 44 is achieved. Slide out the second slide rod 44, and slide the Y-shaped frame 42 out of the groove of the second protective sleeve 43. The Y-shaped frame 42 drives the first protective sleeve 41, and then the first protective sleeve 41 and the second protective sleeve 43 can be removed from the waist-mounted fan body 1. Then push the sliding plate 26. The sliding plate 26 compresses the spring 29. By setting the spring 29, the effect of automatically returning the sliding plate 26 is achieved, avoiding the situation where the sliding plate 26 cannot bounce back. The sliding plate 26 slides in the groove of the waist-mounted fan body 1. When the sliding plate 26 pushes the buckle 24 and releases the limit of the buckle 24 by the groove of the waist-mounted fan body 1, the flip cover 3 drives the connecting block 22 to rotate and open on the arc surface of the rotating rod 21 under the action of the torsion spring 23. By setting the torsion spring 23, the effect of automatically returning the sliding plate 26 is achieved, avoiding the situation where the sliding plate 26 cannot bounce back. That's it.
