Further, an air passage is formed inside the apparatus of the present invention, and it is avoided that the sucked air collides with the internal structure of the apparatus to lose energy, and the blowing efficiency of the outlet 102 is improved. When the blowout amount is the same, the power of the wind turbine 3 is reduced, so that the device of the present invention has a smaller volume than the conventional wearable fan.

FIG. 6 is a schematic disassembled structure diagram of a part of the small fan device according to the embodiment of the present invention, and in one embodiment of the embodiment of the present invention, as shown in FIGS. The housing upper lid 1 is a cube with an open bottom end, includes one upper surface and four side surfaces, suction ports 101 are provided on two opposing side surfaces of the housing upper lid 1, and an outlet 102 is a housing upper lid 1. It is provided on one side of the other two opposing sides, with two suction surfaces and one blowing surface. By providing the suction ports 101 on the two opposite side surfaces of the housing upper lid 1, the amount of air guided to the negative pressure region 7 increases, and the amount of blown air increases. In a conventional wearable fan worn on a wrist, a suction port 101 is provided at the end of the windmill 3, and the suction port 101 is easily completely blocked by a sleeve, which has a negative effect on air suction. Since the 101 is provided on the two opposite side surfaces of the housing upper lid 1, the suction port 101 is less likely to be completely blocked by the sleeves, and the effect of improving air suction is obtained.

By discharging the air from the air outlet 102 communicating with the 311 to the outside of the housing upper lid 1, the air sucked into the negative pressure region 7 is prevented from diffusing around the four circumferences and the turbulent flow of the air inside the housing upper lid 1. , The blowing efficiency of the outlet 102 is improved. When the turbo blade 32 of the wind turbine 3 rotates the air and works on the air to increase the momentum, the air is swung around the four circumferences of the turbo blade 32 by the action of centrifugal force, and the kinetic energy is generated by the baffle plate 31. After being converted into the form of pressure and discharged from the outlet 311 of the baffle plate 31 and the air inside the wind turbine 3 is discharged, the pressure above the wind turbine 3 is lower than the pressure at the first baffle plate 5, and the pressure. Due to the action of the difference, air is sucked into the wind turbine 3 again, and in this way, air is constantly discharged from the outlet 311 of the baffle plate 31.
