Wherein, the intermediate cavity 9 is provided to make the appearance of the fan more beautiful, and the driving motor 1 and the fan blade 2 are not exposed, making it safer and more reliable.
[0046] The top of the middle chamber 9 is connected with a blowing channel 11, and the end of the blowing channel 11 is connected with a wind direction adjusting device;
[0047] The wind direction adjustment device includes a cylindrical wind direction adjustment cover 12, the bottom of the wind direction adjustment cover 12 is provided with a direction adjustment air inlet, the side wall of the wind direction adjustment cover 12 is provided with a direction adjustment air outlet 13, and the wind direction adjustment cover 12 is provided with The direction-adjusting fan blade 14 that converts the wind direction to the horizontal direction is connected with a rotating shaft 15 axially arranged along the wind direction adjusting cover 12, the top of the rotating shaft 15 is rotatably connected with the top of the wind direction adjusting cover 12, and the bottom of the rotating shaft 15 The end is connected with the bottom of the wind direction adjusting cover 12 through a thrust ball bearing 16.

[0049] An ultrasonic mosquito repellent device 17 is connected to the water tank 4.
[0050] The main function of the fan is to cool down. In general, the temperature in the hot summer is higher, and the relative air temperature is higher. Therefore, the fan is most commonly used in summer, and the relative summer mosquitoes are more active and easy to occur to the human body. Therefore, the multifunctional fan is combined with the ultrasonic mosquito repellent device 17 to realize a dual purpose and has the function of cooling and repelling mosquitoes, which further reflects the versatility of the fan.
