At present, there is no micro fan device found on the market that can be used with computers. The computer has become a good partner for people to get along with day and night, especially the portable computer.Because it is equipped with a charging power supply, and the display screen and the host computer form a flip-lid box, it is very convenient to carry.The computer can be used without being limited by the site and facilities.It can be used anywhere, such as outdoors or in tents or on cars, and so on, so it is more popular with people.

However, due to the fact that the laptop computer is single-machine type and lacks the desktop computer to be placed in the environment where the microcomputer works as a room, the common desktop computer is mostly placed in the room with air conditioning.When the computer is used in hot summer, the operator will not find the heat unbearable, while the laptop computer is different.Due to the randomness of using the ring mirror, especially in hot summer, when the computer is used in the field and other places where cooling facilities cannot be provided, the operator cannot obtain the support of cooling facilities, so it is inevitable to feel the heat during operation. On the other hand, if the computer is in a state of bad heat dissipation for a long time, it is easy to damage the components of the computer and affect the service life of the computer.

The invention relates to a miniature fan device matched with a computer, which comprises a miniature fan driven by a miniature direct current motor, a supporting rod with a USB connecting cable, wherein the supporting rod is a bendable supporting rod; the miniature fan is arranged on the supporting rod; the USB connecting cable penetrates through the middle of the supporting rod; connectors at two ends of the cable are respectively arranged on two ends of the supporting rod; and a button switch and a USB connector are sequentially arranged on the shell of the miniature fan. The power supply access end of the DC motor is electrically connected with one end of the button switch, the other end of the button switch is electrically connected with the USB connector, one end of the USB connection cable is electrically connected with the USB connector, and the other end of the USB connection cable is electrically connected with the corresponding interface of the computer.The USB connector of the micro fan is utilized and is connected with the USB interface of the computer through the USB connection cable, so that the micro fan can work by using the power supply of the computer.
