[0024] The following further describes the detailed implementation manners of the present utility model with reference to the accompanying drawings:

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] As Figures 1 to 4 shown, an intelligent control fan with human face recognition and gesture recognition includes a fan base 1 and a fan head 2. The fan head 2 is installed above the fan base 1. A main motor and fan blades are installed inside the fan head 2, and the main motor drives the fan blades to rotate. A camera 3 is installed in front of the fan head 2. The camera 3 is used to capture image signals. The camera 3 transmits the image signals to a human face recognition module 4 and a gesture recognition module 5. The human face recognition module 4 and the gesture recognition module 5 are respectively electrically connected to a main controller 6. The main controller 6 controls the start or stop of the main motor according to the recognition results. The main controller 5 is electrically connected to the main motor.

[0028] Specifically, when the face recognition module 4 analyzes the image signal and recognizes a face, the face recognition module 4 sends a start signal to the main controller 6. When the face recognition module 4 analyzes the image signal and does not recognize a face, the face recognition module 4 sends a shutdown signal to the main controller 6. When the face recognition module 4 shuts down after recognizing a face, it has a delay function to prevent the fan from stopping when a person briefly leaves. When the gesture recognition module 5 analyzes the image signal and recognizes a power-on gesture, the gesture recognition module 5 sends a start signal to the main controller 6. When the gesture recognition module 5 analyzes the image signal and recognizes a power-off gesture, the gesture recognition module 5 sends a shutdown signal to the main controller 6. When the main controller 6 receives any start signal, the main controller 6 controls the main motor to start. When the main controller 6 receives any shutdown signal, the main controller 6 controls the main motor to shut down. Preset gestures such as extending one finger are power-on signals, and two fingers are power-off signals.

[0029] Specifically, a PCBA board mounting shell 7 is installed in front of the fan head 2. An installation groove 8 is provided inside the PCBA board mounting shell 7. The PCBA board 9 is placed in the installation groove 8. The camera 3, the face recognition module 4, and the gesture recognition module 5 are all integrated on the surface of the PCBA board 9. The PCBA board mounting shell 7 is located at the center position in front of the fan head 2. The PCBA board mounting shell 7 can be fixedly installed at the front fan cover of the fan head 2 through screws or a clamping mechanism.

[0030] Specifically, a PCBA fixing frame 10 is clamped in front of the PCBA board mounting shell 7. Hooks 11 are provided on the outer peripheral side of the PCBA fixing frame 10. Corresponding card slots 12 are provided inside the installation groove 8. The PCBA fixing frame 10 positions the PCBA board 9. The PCBA fixing frame 10 is provided with a first through groove 13 corresponding to the position of the camera 3, that is, the first through groove 13 faces the camera 3.

[0031] Specifically, a touch panel 14 is installed in front of the PCBA fixing frame 10. The touch panel 14 is provided with a total power-on / off touch button, a swing touch button, a timing touch button, a wind speed increase touch button, a wind speed decrease touch button, and a microwave induction start / stop touch button.

[0032] As Figure 5 shown, the intelligent control fan with face recognition and gesture recognition further includes a support rod 15, a fan head rotation mechanism, and a connecting column 16. The support rod 15 is installed above the fan base 1. The fan head rotation mechanism is installed at the top of the support rod 15. The fan head rotation mechanism drives the connecting column 16 to rotate. The fan head 2 is installed in front of the connecting column 16. When the camera 3 captures the movement of a face, the fan head rotation mechanism drives the fan to rotate and blow air following the face.

[0033] Specifically, the fan head rotation mechanism includes a secondary motor 17, a gear 18, and a gear ring 19. The motor housing of the secondary motor 17 is fixedly connected to the connecting column 16. The output shaft of the secondary motor extends downward to install the gear 18. The gear 18 meshes with the gear ring 19. The gear ring 19 is fixed to the upper end of the support rod 15. When the secondary motor 17 drives the gear 18 to rotate, since the gear ring 19 does not move, the secondary motor 17 will drive the connecting column 16 to rotate. In addition, a rotating bracket 20 is fixedly installed behind the fan head 2, and the connecting column 16 is hinged to the rear of the rotating bracket 20 through a rotating shaft 21. In this way, the fan head 2 can rotate up and down around the rotating shaft 21 to adjust the angle.
