[0049] Starting and air flow generation:

[0050] When the user presses the function button 72 to start the fan, the control circuit board 71 receives a starting signal and sends an instruction to the fan assembly. The fan 21 in the fan assembly starts to rotate after receiving the instruction and generates air flow. The air flow enters the inside of the fan assembly through the fan air flow inlet 23 and is accelerated by the fan 21.

[0051] Cold-heat conversion and conduction:

In the second air duct 61, the heated (or unheated, depending on the working mode of the electronic cooling sheet 31) airflow is exhausted through the second air outlet 62 and can be used for other purposes (such as heating clothes or the environment). The user can adjust the working state of the electronic cooling sheet 31 by operating the function button 72, thereby controlling the cooling or heating effect of the fan.

[0058] Clothes separation and smooth airflow:

[0059] To ensure smooth airflow, the utility model also designs a clothes separation hook 8. When the fan is hung on the waist, the clothes separation hook 8 separates the fan from the user's clothes, avoiding the obstruction of the clothes to the airflow passage. This design not only improves the cooling efficiency of the fan but also ensures the comfort of the user during wearing.

[0060] The portable cooling waist-mounted fan of the utility model has the advantages of compact structure, comprehensive functions, portability, and is suitable for various user groups such as outdoor workers and athletes, and performs well in providing a cool and comfortable user experience.
