This one-piece design helps to reduce the number of parts and eliminates the connection point between the support portion 11 and the air outlet portion 12. This can reduce potential mechanical failures or damage and increase the service life and reliability of the neck-hanging fan. At the same time, the one-piece structure also enhances the overall stability of the fan, making it more stable and reliable during wearing and use.

[0047] In a specific embodiment, the air guide assembly 20 includes a driving member 21 and a fan blade 22, the driving member 21 is fixedly connected in the wind channel 122, the output end of the driving member 21 is fixedly connected to the fan blade 22, and the driving member 21 is used to drive the fan blade 22 to rotate to draw air into the wind channel 122.

[0048] Specifically, the combination of the driving member 21 and the fan blades 22 enables the air guide assembly 20 to effectively draw external air into the wind channel 122. The driving member 21 provides power to drive the fan blades 22 to rotate, thereby generating airflow. The fan blades 22 move with the rotation of the driving member 21, sucking air from the air inlet 121 into the wind channel 122, providing the required airflow for the fan system. This design can ensure the normal operation of the fan system and improve its air suction efficiency and wind output.

[0049] Furthermore, the driving member 21 is fixedly connected in the wind channel 122, so that the wind can be directly drawn into the wind channel 122, and the driving member 21 provides power to drive the fan blades 22 to rotate. The fan blades 22 move with the rotation of the driving member 21, generate airflow and draw the external air into the wind channel 122. Through the synergistic effect of the driving member 21 and the fan blades 22, the external air is effectively drawn into the wind channel 122, providing the required airflow for the fan system, and realizing the normal operation of the fan.
