[0002] With the improvement of people's living standards and the increasing frequency of outdoor activities, people's demand for portable cooling devices and mobile charging devices is becoming more and more urgent in hot weather. Handheld fans, as a common portable cooling tool, are widely used in people's daily life, outdoor travel and other scenarios due to their small size, light weight and easy portability. However, existing handheld fans have relatively limited functions, mostly only providing cooling. When outdoors, electronic devices such as mobile phones often run out of power, affecting normal use. This necessitates carrying a power bank, which not only increases the burden of travel but can also cause inconvenience if forgotten or the power bank is out of power. Therefore, we propose an improvement: a handheld fan with a power bank. Utility Model Content
