However, existing fans have a single function and can only meet people's needs for cooling down. In summer, not only is the weather hot, but there are also many mosquitoes, especially at night. When people go out, they not only need to prepare fans but also mosquito repellent, which increases the burden of travel and is less convenient.

[0003] After searching, it was found that a mosquito-repellent fan was disclosed in a Chinese patent with authorization announcement number CN202746241U, including a mosquito-repellent lamp post with the upper end connected to the fan head, the lower end of the mosquito-repellent lamp post connected to the lamp holder, the lamp holder embedded in the base, fan blades riveted on the fan head, and a power cord extending into the base to connect to the lamp holder and the fan head.
