Description
Technical Field
[0001] The utility model relates to the field of fans, and particularly to an intelligent fan controlled by microwave induction. Background Art
[0002] Traditional fans usually require manual switching and speed adjustment, which is not convenient to use. Sometimes, the user leaves the working range of the fan for a long time but does not turn off the fan, resulting in waste of electric energy and resource waste. Therefore, it is necessary to develop an intelligent fan that can automatically sense when a person leaves and turn off, and start when a person approaches, to meet the flexible use requirements. Summary of the Utility Model
[0003] Aiming at the above-mentioned defects existing in the prior art, the technical problem to be solved by the utility model is to provide an intelligent fan that can automatically sense the movement of a human body or an object and can automatically turn on or off the fan without any action. The specific technical solutions are as follows:
[0004] An intelligent fan controlled by microwave induction, comprising a fan base, a fan head, a microwave radar sensor, and a main controller. The fan head is installed above the fan base. An electric motor and fan blades are installed inside the fan head, and the electric motor drives the fan blades to rotate. The microwave radar sensor is used to detect whether a person or an object enters the microwave signal sensing range in front of the fan. The microwave radar sensor sends a signal to the main controller, and the main controller controls the electric motor to start or stop.
[0005] As a preferred solution of the utility model, a PCBA board mounting shell is installed in front of the fan head. An installation groove is provided inside the PCBA board mounting shell, and the PCBA board is placed in the installation groove. The microwave radar sensor and the main controller are integrated on the surface of the PCBA board.
[0006] As a preferred solution of the utility model, a PCBA fixing frame is snap-fitted in front of the PCBA board mounting shell. Hooks are provided on the outer peripheral side of the PCBA fixing frame, and corresponding slots are provided inside the installation groove. The PCBA fixing frame limits the PCBA board.
[0007] As a preferred solution of the utility model, a touch panel is installed in front of the PCBA fixing frame. The touch panel is provided with a total power on / off touch button, a timing touch button, an increase wind speed touch button, a decrease wind speed touch button, and a microwave induction start / stop touch button.
[0008] As a preferred solution of the utility model, the PCBA board mounting shell is located at the center position in front of the fan head.
[0009] As a preferred solution of the utility model, a support rod is further included. The lower end of the support rod is connected to the fan base, and the upper end of the support rod is connected to the fan head.
[0010] Beneficial effects: When the intelligent fan of the present utility model is working, the microwave radar sensor detects whether there is a person or an object entering the microwave signal sensing range in front of the fan. When there is a person, the microwave radar sensor sends a start signal to the main controller, and the main controller controls the motor to start, so that the fan blades rotate. When there is no one, the microwave radar sensor sends a shutdown signal to the main controller, and the main controller controls the motor to shut down, so that the fan blades stop rotating. The opening and closing are controlled intelligently, which is very flexible and convenient to use, and is more energy-saving and power-saving, meeting the use requirements.
