[0040] Example 2:

[0041] The following is the working principle of the portable air conditioner fan of the utility model:

[0042] like Figure 1-2 As shown, the housing 10 of the present invention also has a circuit board installed therein. The circuit board is provided with a power supply circuit, a circuit for controlling the air source generating device, and a circuit for controlling the operation of the refrigeration device. The circuit board is also provided with a USB port, a Type C port, and a DC port.

[0043] The power supply of this utility model can be either internal or external. Both internal and external power supplies are rechargeable. This embodiment uses an external power supply as an example. The external power supply is connected to a USB port via a USB power cable to supply power to the circuit board.

[0044] When the switch is turned on, the wind source generating device and the refrigeration device work synchronously. The wind source generating device adopts a single-sided turbine, which supplies air in the direction of the refrigeration device after working.

[0045] After the refrigeration device is working, the heat generated by its heat sink is discharged from the heat exhaust hole 12, and its refrigeration plate is cooled. When the flowing air passes through the refrigeration plate, the flowing air is cooled to form cold air. The cold air enters the L-shaped air duct in the hanger 20 from the air duct opening 23, and is finally discharged from the first air outlet 44 and the drawing groove 43.

[0046] The utility model installs a hanger 20 on the casing. The hanger 20 is a detachable structure. An L-shaped air duct is provided inside the hanger 20. The L-shaped air duct is connected to the inner cavity of the casing. The refrigerated air enters the L-shaped air duct and is discharged from an air outlet 44 and a drawing groove 43 of the hanger 20. After the hanger 20 is installed, the air outlet is far away from the air inlet and the heat exhaust port, which reduces the mixing of hot air and cold air at the air outlet and improves the cooling effect.

[0047] The utility model is provided with two air outlets, one of which is at the tail of the pendant and the other is at the outer side of the wide part of the pendant, and an aluminum sheet is installed on the second air outlet, and a wire drawing groove 43 is opened on the aluminum sheet to prevent the wide part of the pendant from fitting with the contact surface, thereby preventing the air outlet from being blocked.
