At any time, industrial technology is gradually improving, and the global warming problem is becoming more and more serious, which causes the global climate to change drastically, which in turn causes the summer temperature to remain high. In order to eliminate the heat brought by the summer, most people use air-conditioning or fans to reduce the indoor temperature. However, the structure of a general fan is usually divided into a cold fan used in summer or a warm fan used in winter, so that the user needs to put away the unused cold fan or warm fan when the seasons alternate, not only occupying space, but also purchasing different functions.
