Description

Technical Field

[0001] This application relates to the field of fans, and more particularly to a fan that can adjust its direction based on human face detection. Background Technology

[0002] An electric fan, also known as a fan or ventilator, is a household appliance that uses an electric motor to drive fan blades to rotate, thereby accelerating air circulation. It is primarily used for cooling and air circulation. It is widely used in homes, classrooms, offices, shops, hospitals, hotels, and other places.

[0003] Traditional fans mostly require manual or remote control operation and lack intelligent sensing and automatic control functions. When the user moves away from the fan's working range, the fan cannot change its working range according to the user's position, resulting in a mismatch between the fan's working range and the user's position. This can easily lead to the fan blowing ineffectively or requiring the user to manually change the fan's working range, making the fan inconvenient to use and resulting in a generally poor user experience. Summary of the Invention

[0004] In order to enable the fan to change its working range according to the user's position and improve the user's experience, this application provides a fan that can adjust its direction based on face and human shape detection.

[0005] The fan provided in this application, which can adjust its direction based on face and human shape detection, adopts the following technical solution:

[0006] A fan that can adjust its direction based on human face detection includes a housing, a functional mechanism, and a control mechanism. The housing includes a base and a rotating part, and the rotating part is rotatably disposed on the top of the base.

[0007] The functional mechanism includes a blower assembly, a camera module, and a drive component. The blower assembly is disposed within the rotating part and is used for blowing air. The camera module is disposed within the rotating part and is used for capturing the human body's movement trajectory and position changes. The drive component is disposed within the base and is used to drive the rotating part to rotate relative to the base.

[0008] The control mechanism is located inside the base and is used to control the functional mechanism and provide power to the functional mechanism. When the camera module detects that the human body has moved and its position has changed, the control mechanism controls the drive component to drive, so that the working range of the rotating part changes with the position of the human body.

[0009] Optionally, the driving component is a drive motor, which is fixedly installed inside the base. The bottom of the rotating part is provided with a rotating groove, and the output shaft of the drive motor passes through and is engaged with the rotating groove.

[0010] Optionally, a rotating bearing is provided between the rotating part and the base part, the inner ring of the rotating bearing is fixedly connected to the rotating part, and the outer ring of the rotating bearing is fixedly connected to the base part.

[0011] Optionally, the rotating part includes a support body and a rotating body. The support body is connected to the base body. Rotating shafts are fixedly provided at both ends of the rotating body. Rotating holes are provided at both ends of the support body. When the rotating body is rotatably connected to the support body, the two rotating shafts pass through and are rotatably connected to the two rotating holes respectively. The axis of rotation of the support body relative to the base body is a vertical axis, and the axis of rotation of the rotating body relative to the support body is a horizontal axis. The horizontal axis and the vertical axis are perpendicular to each other.

[0012] Optionally, at least one friction washer is provided between the support body and the rotating body, with one side of the friction washer abutting against the support body and the other side of the friction washer abutting against the rotating body.

[0013] Optionally, the rotating part has a mounting groove, the camera module is located in the mounting groove, and the opening of the mounting groove is provided with a mounting cover, which closes the mounting groove.

[0014] Optionally, the control mechanism includes a control circuit board and a power module. The control circuit board is disposed inside the base and is electrically connected to the blower assembly, the camera module, and the drive component. The power module is disposed inside the base and is electrically connected to the control circuit board. The power module is used to provide electrical energy.

[0015] Optionally, the control circuit board is rotatable and electrically connected to a control rocker arm, and the base has a through-hole rocker arm slot, through which the control rocker arm passes and slides to engage with the rocker arm slot.

[0016] Optionally, the control circuit board is fixedly and electrically connected to a charging interface, and the base has a through-hole interface slot through which the charging interface passes.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When a user needs to use the fan for cooling, the control mechanism activates the fan assembly, enabling it to blow air. When the user moves and needs to remain within the fan's operating range, the control mechanism activates the camera module. The camera captures the user's movement and position changes, transmitting these signals to the control mechanism. The control mechanism analyzes these signals and intermittently controls the drive mechanism to open and close, causing the drive to rotate in accordance with the user's movement and position changes. The fan in this application can change its working range according to the user's position, thus improving the user's experience. It addresses the shortcomings of traditional fans, which often require manual or remote control operation, lack intelligent sensing and automatic control functions, and fail to adjust their working range when the user moves out of the fan's range. This mismatch between the fan's working range and the user's position can lead to ineffective airflow or require manual adjustment, resulting in inconvenient use and a generally poor user experience.

[0030] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0031] This application discloses a fan whose direction can be adjusted based on face and human shape detection. (See also...) Figure 1 A fan that can adjust its direction based on face and human shape detection includes a housing 1, a functional mechanism 2, and a control mechanism 3. The functional mechanism 2 is disposed in the housing 1 and is used to perform the fan's blowing function and the function of adjusting the blowing direction according to the face. The control mechanism 3 is disposed inside the housing 1 and is used to control the functional mechanism 2 and to provide power to the functional mechanism 2.

[0032] Reference Figures 2 to 5 In this embodiment, the housing 1 includes a base portion 11 and a rotating portion 12. The rotating portion 12 is rotatably disposed on the top of the base portion 11. The rotating portion 12 includes a support body 121 and a rotating body 122. A rotating cavity 111 is formed on the top of the base portion 11. The support body 121 passes through the rotating cavity 111. A rotating bearing 1111 is provided between the support body 121 and the base portion 11. The inner ring of the rotating bearing 1111 is fixedly connected to the support body 121, and the outer ring of the rotating bearing 1111 is fixedly connected to the base portion 11, so that the support body 121 is rotatably connected to the base portion 11 to achieve... The rotating part 12 and the base part 11 are rotatably connected. Rotating shafts 1221 are fixedly provided at both ends of the rotating body 122. Rotating holes 1211 are provided at both ends of the support body 121. When the rotating body 122 and the support body 121 are rotatably connected, the two rotating shafts 1221 are respectively passed through and rotatably connected to the two rotating holes 1211. The axis of rotation of the support body 121 relative to the base part 11, that is, the axis of the cavity of the rotating cavity 111, is a vertical axis. The axis of rotation of the rotating body 122 relative to the support body 121, that is, the axis of the rotating shafts 1221, is a horizontal axis. The horizontal axis and the vertical axis are perpendicular to each other.

[0033] Reference Figure 4 and Figure 5 In this embodiment of the application, two friction washers 123 are provided between the support body 121 and the rotating body 122. The two friction washers 123 are respectively located on both sides of the rotating body 122. One side of the friction washer 123 abuts against the support body 121, and the other side of the friction washer 123 abuts against the rotating body 122, so that the support body 121 and the rotating body 122 are not easy to rotate relative to each other when subjected to a small external force. For example, the rotating body 122 is not easy to rotate relative to the support body 121 due to the gravity acting on the rotating body 122 itself, thereby making the included angle between the rotating body 122 and the support body 121 relatively stable.

[0034] Reference Figure 6 In this embodiment, the functional mechanism 2 includes a blower assembly 21, a camera module 22, and a drive member 23. The blower assembly 21 is disposed in the rotating part 12 and is used for blowing air. The camera module 22 is disposed in the rotating part 12 and is used for capturing the human body's movement trajectory and position changes, so that the rotating part 12 can rotate according to the direction of the human face, thereby changing the blowing direction of the blower assembly 21. The drive member 23 is disposed in the seat part 11 and is used to drive the rotating part 12 to rotate relative to the seat part 11.

[0035] Reference Figure 7 In this embodiment of the application, the blower assembly 21 includes a blower motor 211 and a blower fan blade 212. The blower motor 211 is fixedly disposed inside the rotating body 122, and the blower fan blade 212 is coaxially fixedly disposed on the output shaft of the blower motor 211 to realize the blower function of the blower assembly 21.

[0036] Reference Figure 8 In this embodiment, a mounting groove 1222 is provided on the front side of the rotating body 122, that is, on the side of the rotating body 122 located in the blowing direction of the blower assembly 21. The camera module 22 is fixedly installed inside the mounting groove 1222. A mounting cover 1223 is provided at the opening of the mounting groove 1222. The mounting cover 1223 closes the mounting groove 1222. The camera module 22 can take pictures of the external environment of the fan through the mounting cover 1223. In this embodiment, the material of the mounting cover 1223 is not limited.

[0037] Reference Figure 9 In this embodiment, the driving component 23 is a driving motor, which is fixedly installed inside the base 11. The bottom of the bracket 121 is provided with a rotating groove 1212. The output shaft of the driving motor passes through and is engaged with the rotating groove 1212 so that when the bracket 121 and the base 11 need to rotate relative to each other, the driving motor drives the output shaft of the driving motor to rotate the bracket 121 relative to the base 11.

[0038] Reference Figure 10 In this embodiment, the control mechanism 3 includes a control circuit board 31 and a power module 32. The control circuit board 31 is disposed inside the base 11 and is electrically connected to the blower motor 211, the camera module 22, and the drive unit 23. The power module 32 is disposed inside the base 11 and is electrically connected to the control circuit board 31. The power module 32 is used to provide electrical energy.

[0039] Reference Figure 10 In this embodiment, the control circuit board 31 rotates and is electrically connected to a control rocker arm 311. The base 11 has a through-hole rocker arm slot, through which the control rocker arm 311 passes and slides into the rocker arm slot 112. The control circuit board 31 is fixed and electrically connected to a control button 312 and a control button 314.

[0040] Optionally, the fan in this embodiment of the application is equipped with multiple wind speeds, such as three or four wind speeds. The control button 312 is an on / off switch and a speed adjustment switch. When the control button 312 is pressed for the first time, the blower motor 211 is started, causing the fan to begin blowing air at speed one. Pressing the control button 312 a second and third time adjusts the wind speed to speed two and three respectively. Pressing the control button 312 a fourth time turns the fan off.

[0041] The joystick 311 is used to control the opening and closing of the drive unit 23, thereby controlling the rotation of the fan. Furthermore, when the joystick 311 is moved from top to bottom, the drive unit 23 starts and the fan rotates to blow air. When the joystick 311 is moved from bottom to top to reset, the drive unit 23 is turned off and the fan stops rotating.

[0042] Control button 314 is used to turn the camera module 22 on and off.

[0043] Reference Figure 10 In this embodiment, the control circuit board 31 is fixed and electrically connected to a charging interface 313. The base part 11 has a through-hole interface slot, and the charging interface 313 passes through the interface slot. The charging interface 313 is used to charge the power module 32.

[0044] The implementation principle of a fan that can adjust its direction based on face and human shape detection in this application embodiment is as follows: When a user needs to use the fan for cooling, the blowing component 21 can be turned on by the control button 312, so that the blowing component 21 can work and blow air. When the fan needs to rotate, it can be controlled by the joystick 311. When the user moves and needs to keep their position within the working range of the blowing component, the camera module 22 can be turned on by the control button 314, so that the camera module 22 can capture the movement trajectory and position changes of the human body, and transmit the signals of the human body's movement trajectory and position changes to the control circuit board 31 of the control mechanism 3. The control circuit board 31 analyzes the signals of the human body's movement trajectory and position changes, and intermittently controls the opening or closing of the drive component 23, so that the drive component 23 is driven according to the human body's movement trajectory and position changes, so that the rotating part 12 rotates according to the human body's movement trajectory and position changes, and always faces the human body. To ensure that the user remains within the working range of the blowing component 21, the fan in this application can change its working range according to the user's position, improving the user's experience. This addresses the issues of traditional fans, which often require manual or remote control operation, lack intelligent sensing and automatic control functions, and fail to adjust their working range when the user moves out of the fan's working range. This mismatch between the fan's working range and the user's position can lead to ineffective airflow or require the user to manually change the fan's working range, resulting in inconvenient use and a generally poor user experience.

[0045] When the camera module 22 is not activated, the fan can rotate and blow air by controlling the remote control 311. The fan can rotate in a left-right oscillating pattern. After the camera module 22 is activated, the fan's rotation direction is controlled by the control circuit board 31 based on the signal captured by the camera module 22. Furthermore, the camera module 22 can be activated either when the remote control 311 activates the fan's rotation function or when the fan is not rotating. Even when the fan is not rotating, if the camera module 22 is activated, it can still control the fan's rotation, and the direction of rotation is controlled by the control circuit board 31 based on the signal captured by the camera module 22.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
