As a preferred embodiment: the controller is a single chip microcomputer controller.

As a preferred embodiment: and a battery for supplying power to the motor is arranged in the shell and is connected with the motor, the plug-in interface and the controller.

As a preferred embodiment: the fan also comprises an indicator light, an indicator light key for controlling the indicator light is arranged on the shell, the indicator light key is connected with the controller and the indicator light, and the brightness of the indicator light is changed along with the gear of the fan.

As a preferred embodiment: the lower end of the handle is provided with a base.

As a preferred embodiment: the circuit board and the battery are both mounted in the handle.

As a preferred embodiment: the button is arranged on the handle.

Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, can know by above-mentioned technical scheme, can store the fan and adjust the gear last time and resume the controller of the gear last time promptly when the fan is opened once more through setting up in handheld fan. Therefore, the gear is prevented from being adjusted by key operation again, the use habit of a user can be adapted by opening the fan, and the use experience of the fan is improved; meanwhile, the keys are arranged for the user to adjust according to requirements, different requirements of the user are met, and convenience is provided for the user.

To more clearly illustrate the structural features and effects of the present invention, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
