Detailed Description
The utility model discloses as shown in fig. 1 and fig. 2, a fan is handed to induction type, including casing 10, motor 20, flabellum 30, circuit board 40, inductor 50 and button 60, wherein:
the casing 10 comprises a main casing 11 and a handle 12 connected to the lower end of the main casing 11, wherein the lower end of the handle 12 is provided with a base 13, and the base 13 can be a sucker or other structures capable of stably placing the fan on a table; the base 13 may also be designed as a plug-in type to facilitate the use of a fan inserted somewhere.
The motor 20 is mounted in the main housing 11, and the fan blades 30 are mounted on the shaft end of the motor 20.
The circuit board 40 is installed inside the handle 12, and the circuit board 40 is provided with a controller 41 (the controller 41 is a single chip microcomputer controller with a memory function) for collecting instructions of the sensor 50 and the keys 60 to control the start and stop of the fan and the gear adjustment, and an electrical interface 42; the sensor 50 is used for sensing a temperature of a human body or a distance between the human body and the fan (the sensor 50 may be an infrared sensor, a distance sensor or a temperature sensor, which is mainly used for sensing a signal and then sending an instruction to the controller), the sensor 50 is disposed on the main housing 11 or the handle 12 and connected to the controller 41; the button 60 is provided on the handle 12 for manually operating the fan, and the button 60 and the motor 20 are connected to the controller 41, respectively. A battery 70 for supplying power to the motor 20 is mounted in the handle 12, and the battery 70 is connected to the motor 20, the controller 41, and the plug interface 42.
