Therefore, they should not be construed as limitations on this utility model. Example

[0033] like Figure 1 and Figure 2 As shown, this utility model proposes an intelligent fan based on a brushless motor, including a fan body 1 and a handle 2 located at the bottom of the fan body 1. The fan body 1 contains fan blades 3 and a brushless motor 4. The fan blades 3 are connected to the output shaft of the brushless motor 4, and rotation is achieved by the drive of the brushless motor 4. The brushless motor 4 is an ECM3015 brushless DC motor, characterized by high efficiency and low noise. The fan body 1 has a portable structure, is made of lightweight materials, and is easy to carry.

[0034] refer to Figure 3 As shown, the handle 2 is composed of a front cover 21 and a box 22. The box 22 is provided with a folding part 201 and a control part 202 distributed vertically inside.

[0035] The folding part 201 has a U-shaped structure, and the bottom of the fan body 1 is provided with a folding arm 5. The folding arm 5 is rotatably connected to the folding part 201 through a hinge structure 6.

[0036] Combination Figure 4 As shown, the control unit 202 is provided with a main control board 7, and an intelligent sensing module 8 is installed on the main control board 7. The sensing module includes a processor 81, a temperature sensor 82, a humidity sensor 83, and a human infrared sensor 84. The processor 81 is connected to the temperature sensor 82, the humidity sensor 83, the human infrared sensor 84, and the brushless motor 4. The temperature sensor 82 and the humidity sensor 83 are used to detect the ambient temperature and humidity. The sensing part of the human infrared sensor 84 is set on the front of the front cover 21 and is used to detect the human body.

[0037] The processor 81 is an STM32F407 microcontroller, the temperature sensor 82 is a DS18B20 digital temperature sensor, the humidity sensor 83 is a DHT11 digital temperature and humidity sensor, and the human infrared sensor 84 is an HC-SR501 human infrared sensor, which is installed on the front of the fan body 1 to detect the position of the human body.

[0038] Preferably, the front cover 21 has a detection port 23, which corresponds to the intelligent sensing module 8. The housing 22 also has a battery compartment 203 located below the control unit 202. The inner wall of the battery compartment 203 has a limiting buckle for securing the battery 9, which provides power.

Users can remotely control the fan's on / off state, fan speed, direction, and other parameters via a mobile app, and can also view the fan's operating status and environmental data.

[0042] The working principle of this embodiment is similar to that of the above embodiments, except that the intelligent adjustment function and user interaction have been further optimized and expanded. Example

The side end of the folding arm 5 is rotatably connected to the folding part 201 through the hinge. Through the cooperation of the hinge and the folding arm 5, the fan body 1 can be folded or flipped.

[0044] When it is necessary to fold or flip the fan body 1, the fan body 1 can be folded or flipped to a suitable position by means of the hinge and folding arm 5, thereby reducing the size of the fan.

[0045] The present invention and its embodiments have been described above.
