[0035] Embodiment 1:

[0036] See also Figure 1-4, this embodiment provides an intelligent fan, wherein the intelligent fan mainly supplies air to the target direction by means of air discharge, so as to speed up air circulation and achieve the effect of cooling or air circulation. Specifically, the intelligent fan can intelligently control the air supply area that the intelligent fan can cover based on the sensor / image acquisition device, wherein the intelligent control includes but is not limited to the swing amplitude control of the air supply component 20, the start and stop control of the fan 22, the sensor start and stop control, and the voice interaction control. In this embodiment, the air supply area of ​​the intelligent fan includes but is not limited to the 90-degree fan-shaped area and the 180-degree semicircular area. Of course, in order to achieve the sensing range that matches the air supply area of ​​the intelligent fan, the sensor / image acquisition device can achieve full coverage of the air supply area by adjusting the layout position, the layout quantity, and the change of the device type.

[0037] In this embodiment, the intelligent fan receives the collected and processed data sent by the sensor / image acquisition device through the control module 50, and performs at least one function of swing amplitude control of the air supply component 20, start and stop control of the sensor / image acquisition device, and start and stop control of the air supply component 20 based on the data.

[0038] See also Figure 1-2 In terms of specific structure, the smart fan includes a base 10, an air supply component 20, an infrared sensor 30, a camera module 40 and a control module 50, wherein the base 10 is used as a support member, mainly for carrying the air supply component 20 and other components, so that the components of the smart fan can be stably placed on the bottom surface or installed on the wall and ceiling. The air supply component 20 is the main component of the fan for air discharge, and supplies air in the corresponding direction to achieve the fan air discharge effect. In this embodiment, the air supply component 20 can be rotatably mounted on the base 10, and is stably placed / installed on the target ground / wall through the base 10.

[0039] On the other hand, the infrared sensor 30 includes an infrared sensing surface, which is arranged toward the air supply area of ​​the air supply assembly 20, and is used to collect human body heat sources in the air supply area and send a trigger signal. The camera module 40 includes an image collection surface, which is arranged toward the air supply area and is used to collect image data of the air supply area.

[0040] As the sensing element for sensing / collection in this embodiment, the infrared sensor 30 has a human body heat source collection function, and the camera module 40 has a photography function, and the infrared sensing surface of the infrared sensor 30 and the image collection surface of the camera module 40 are respectively arranged toward the air supply area of ​​the air supply component 20, so as to collect the human body heat source data and image data in the air supply area. Among them, the human body heat source data is mainly used to determine whether a user enters the air supply area, so as to determine whether to turn on the camera to adjust the swing amplitude of the head. Of course, this function can also realize the opening control of the fan air supply function. For example, when the fan is in the standby state, if it is detected that the user enters the air supply area, a trigger signal is sent to the control module 50. After the control module 50 receives the trigger signal, it automatically turns on the fan's air supply function according to the current situation of the fan to supply air. In terms of swing control, after the control module 50 receives the trigger signal, it turns on the camera module 40 to collect images, and recognizes the human body contour in the image through the image recognition algorithm, so as to obtain the positions of each human body in the air supply component 20, and adjusts the swing amplitude of the air supply component 20 based on the human body position.

[0041] It is worth noting that the image recognition algorithm can use the current existing image analysis algorithm to recognize the human body contour in the picture and obtain the recognition data with the human body position. The recognition algorithm is embedded in the camera module 40 or the control module 50, and does not require those skilled in the art to use computer programs for creative development. Therefore, the main protection of the housing is the hardware structure of the camera module 40, the infrared sensor 30 and the control module 50 directly or indirectly integrated in the smart fan, and there is no program algorithm development step.

[0042] See also Figure 3-4As one of the key points, the control module 50 of this embodiment is data-connected with the infrared sensor 30, and is control-connected with the camera module 40 and the air supply component 20, and is used to turn on the camera according to the trigger signal of the infrared sensor 30, and receive and adjust the swing amplitude of the air supply component 20 according to the position of the human body in the image data. Among them, data connection means that the control module 50 can exchange data with the infrared sensor 30, that is, the control module 50 can receive the human body heat source data and the corresponding trigger signal collected by the infrared sensor 30. For example, if the control module 50 has the corresponding human body heat source data processing function, it can directly receive the human body heat source data and monitor the human body heat source data to achieve the effect of identifying whether a human body enters the air supply area. Of course, the infrared sensor 30 can also have a corresponding judgment function, that is, when a human body enters the corresponding heat source collection area, the infrared sensor 30 senses the trigger and sends the corresponding trigger signal to the control module 50, and the control module 50 turns on the camera module 40 according to the trigger signal and adjusts the swing amplitude of the air supply component 20. The control connection means that the control module 50 can control the start and stop of the air supply component 20 and the corresponding swing control by sending corresponding control signals to the air supply component 20.

[0043] See also Figure 2 Preferably, in terms of the air supply component 20, the air supply component 20 includes a steering control 21 and a fan 22, the fan 22 is rotatably mounted on the base 10 through the steering control 21, and the control module 50 is control-connected with the steering control 21 to control the swing amplitude of the fan 22. The steering control 21 specifically includes a driving motor 211 and a rotating bearing 212, the rotating bearing 212 is drivingly connected to the driving motor 211, and the driving motor 211 drives the rotating bearing 212, thereby driving the fan 22 to rotate in the air supply area.

[0044] See also Figure 4 As a preferred embodiment, the control module 50 includes a control chip 51, and the control chip 51 includes an image acquisition port 52, an infrared data acquisition port 53, and a function control port 54. The control chip 51 is connected to the camera module 40 through the image acquisition terminal, and is used to output the image data acquired by the camera module 40 to the control chip 51. The control chip 51 is connected to the infrared sensor 30 through the infrared data acquisition terminal, and is used to send the human body heat source data acquired by the infrared sensor 30 to the control chip 51.

[0045] On the other hand, the control chip 51 is also connected to the camera module 40 and the air supply component 20 through the function control port 54. The function control port 54 mainly enables the camera module 40 and the air supply component 20 by outputting the corresponding high level or low level. After the camera module 40 and the air supply component 20 receive the corresponding enable signal, the internal circuit is turned on or off accordingly to achieve the start-stop control effect. The control structure is simple and practical. The control chip 51 can be used to collect the image acquisition end and the camera module 40 to control the swing amplitude of the air supply component 20, realize the intelligent swing of the fan, and can perform single-person tracking air supply / multi-person precise shaking air supply in specific scenarios. There is no need to manually adjust the rotation direction during use, which improves the air supply quality and effectively improves the user experience.

[0046] Of course, the control structure also controls the switch of the air supply component 20, the camera module 40 and the infrared sensor 30, and performs corresponding switches according to whether there is someone in the air supply area, thereby realizing the intelligent opening and closing of the fan, avoiding waste of resources, achieving energy saving, and reducing the user's electricity costs.

[0047] As a preferred embodiment of the present invention, the camera module 40 includes a camera and a camera processor, the camera is data-connected to the camera processor, and the camera processor is used to receive image data from the camera and send the recognition data to the control module 50 after recognizing the human body contour. The smart fan improves the efficiency of image acquisition and recognition through the camera module 40 with built-in data processing function, and ensures the sensitivity and reliability of the swing adjustment of the air supply component 20.

[0048] As a preferred embodiment of the present invention, the infrared sensor 30 includes an infrared receiving unit and an infrared processor. The infrared receiving unit is data-connected to the infrared processor. The infrared processor is used to receive the thermal radiation data collected by the infrared receiving unit, obtain the human body heat source trigger signal, and send it to the control module 50. Since the sensing of the infrared sensor 30 has a certain delay and jamming, the present embodiment sends a trigger signal through the infrared sensor 30, and turns on the camera module 40 according to the trigger signal. Subsequently, the human body position device is realized through the camera module 40, and the intelligent control of the wind direction swing can be achieved.

[0049] In a preferred embodiment, the intelligent fan further includes a circuit board, a control module 50 is mounted on the circuit board, the circuit board is built into the base 10, and the control chip 51 is integrated on the circuit board and electrically connected to other components through the leads on the circuit board. In some embodiments, the camera module 40 and the infrared sensor 30 are arranged on the base 10 and electrically connected to the control module 50 through the circuit board. Such a design can make the integration of the control chip 51, the camera module 40, and the infrared sensor 30 more intensive, shorten the wire length, facilitate maintenance, and reduce costs. Of course, in some embodiments, the control module 50 of the intelligent fan can also be connected through wireless connections including Bluetooth connection and LAN connection to the camera module 40 and the infrared sensor 30 for data exchange, thereby calling the equipment in the room to collect the human body position, and finally achieving fan swing control.

[0050] In order to improve the user experience, the smart fan also includes a shielding cover for shielding the camera, which is movably arranged on the base 10 by flipping or sliding, and is arranged on one side of the camera. This design can shield the camera module 40 when the fan is not in use to prevent user privacy.

[0051] In terms of data interaction, the control end of the infrared sensor 30 is connected to the first enabling end 55 of the control module 50, and the first enabling end 55 is used to output a shutdown signal to the infrared sensor 30 when the camera module 40 is turned on, and output a start signal to the infrared sensor 30 when the camera is turned off. The camera module 40 is connected to the second enabling end 56 of the control module 50, and the second enabling end 56 is used to send a start signal to the camera module 40 when the control module 50 receives a trigger signal from the infrared sensor, and send a shutdown signal to the camera module 40 when the camera module 40 does not collect human image data. The control module 50 can realize intelligent control of the camera and the infrared sensor 30 in the above manner, and the interaction between the two can effectively save resource waste and achieve energy saving effects.

[0052] In order to provide a better operation experience, a specific implementation process and data interaction process are provided. When the air supply component 20 of the smart fan is not turned on, when the user enters the air supply area, the infrared sensor 30 collects the heat source of the human body and sends a trigger signal to the control chip 51. The control chip 51 sends an output control signal for turning on the air supply component 20 of the smart fan according to the trigger signal, starts the air supply component 20 of the smart fan, turns on the camera, and turns off the infrared sensor 30. During the air supply period, the camera collects the image of the air supply area, identifies the identification data with the human body position and sends it to the control chip 51. The control chip 51 controls the turning space of the air supply component 20 based on the identification data, and then controls the swing amplitude of the air supply component 20. Correspondingly, when the air supply component 20 of the smart fan is turned on, when the camera collects and recognizes that there is no user in the air supply area within a time unit, a trigger signal is sent to the control chip 51. The control chip 51 sends an output control signal for closing to the air supply component 20 according to the trigger signal, turns off the air supply component 20 of the smart fan, turns off the camera at the same time, turns on the infrared sensor 30, and the infrared sensor 30 performs real-time detection and repeats the above steps.

The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application.
