Description

technical field [0001] The invention relates to a fan, in particular to a portable adjustable-speed fan. Background technique [0002] In the summer morning, although the sun is not strong, the temperature is very high. At this time, it is most suitable if there is a gust of breeze; The cooling effect of the strong wind in the city couldn't be better; although there is no dazzling sun in the evening, the weather is still muggy, and the wind is still important to us. But at different times and under different circumstances, our demand for wind is different, and the commonly used portable fans at present cannot adjust the wind speed, and the wind blown out is not cool enough, and the cooling effect is not good. Contents of the invention [0003] In view of the above problems, the present invention provides a portable adjustable-speed fan. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: a portable adjustable speed f...
