Description

Technical Field

[0001] This invention relates to the field of handheld portable fan technology, specifically to a portable fan that integrates thermal imaging temperature measurement and can automatically adjust its speed based on temperature. Background Technology

[0002] Currently, portable air delivery products such as handheld fans and desktop fans are widely used in homes, offices, and outdoors, mainly for localized cooling. Traditional portable fans generally use multi-speed manual adjustment or fixed-speed cycling control methods, requiring users to manually press buttons or touch controls, and cannot adaptively adjust according to the actual temperature of the target being cooled.

[0003] In practical use, the optimal fan speed should be determined by the real-time temperature of the target being cooled, but existing fans generally have the following technical defects: 1. It lacks non-contact temperature detection capabilities, making it impossible to obtain the target temperature. The fan speed does not match the actual heat dissipation requirements, which can easily lead to overcooling or insufficient cooling, resulting in a poor user experience.

[0004] 2. The wind speed needs to be adjusted manually and repeatedly, which is inconvenient for one-handed operation and has a low level of intelligence.

[0005] 3. A few fans with temperature control functions use contact temperature measurement, which cannot meet the needs of non-contact temperature measurement scenarios. The speed adjustment response is lagging, the control accuracy is low, and it is difficult to achieve precise air delivery and cooling.

[0006] Therefore, existing portable fans cannot achieve contactless temperature measurement and automatic temperature control speed adjustment, and cannot meet users' needs for accurate, convenient and intelligent cooling. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable temperature-controlled fan with thermal imaging. This fan collects the temperature of the target object without contact through a thermal imaging lens and automatically adjusts the motor speed according to the temperature data to achieve precise automatic temperature-controlled air delivery, solving the problems of traditional fans that require manual adjustment, cannot measure temperature without contact, and have inaccurate temperature control.

[0008] The technical solution adopted by this invention to solve its technical problem is: A portable temperature-controlled fan with thermal imaging includes a handle and a fan head. The handle houses a battery and a main control circuit board, while the fan head houses a drive motor. The output shaft of the drive motor is powered by a fan blade shaft, and the end of the fan blade shaft furthest from the drive motor is fixedly connected to the fan blades. The fan head has an air outlet, and a thermal imaging lens is mounted on the air outlet side of the fan head. The detection direction of the thermal imaging lens is consistent with the air outlet direction. The thermal imaging lens and the drive motor are both electrically connected to the main control circuit board, forming an automatic temperature control feedback mechanism.

[0009] Furthermore, the handle is equipped with a display screen, which is installed on the side of the handle away from the air outlet. The orientation of the display screen is opposite to the detection direction of the thermal imaging lens, making it convenient for the user to observe the image when holding the handle.

[0010] Furthermore, the main control circuit board is configured to: adjust the speed of the drive motor according to the target temperature data collected by the thermal imaging lens; the higher the target temperature, the faster the motor speed and the greater the air volume; the lower the target temperature, the slower the motor speed and the smaller the air volume.

[0011] Furthermore, a camera is also provided on the air outlet side of the fan head, and the shooting direction of the camera is consistent with the air outlet direction; the display screen can switch to display thermal imaging heat map, real-time camera view, or a fusion of heat map and real-time view.

[0012] Furthermore, the fan head has a lens bracket and a lens assembly circuit board on the air outlet side. The thermal imaging lens and the camera are both mounted on the lens assembly circuit board and fixed to the fan cover by the lens bracket. The air outlet cover is fixed to the fan head by a buckle.

[0013] Furthermore, the handle is equipped with a power button, operation buttons, and a charging interface, all of which are electrically connected to the main control circuit board; the operation buttons are used to switch the display screen display mode.

[0014] The beneficial effects of this invention are: 1. The thermal imaging lens is set in the same direction as the air outlet, so the heat dissipation target and the temperature measurement target are the same. The target temperature can be obtained without contact. With the automatic temperature control feedback mechanism, it can realize one-handed automatic temperature control and air supply. It is suitable for scenarios where contact temperature measurement is not possible and precise temperature control is required.

[0015] 2. The handle is equipped with a reverse display screen, allowing users to observe the thermal map or fused image in real time, intuitively grasp the target temperature distribution, and facilitate aiming at the target to improve the heat dissipation effect.

[0016] 3. The addition of a camera and support for image fusion display caters to both the intuitive operation needs of ordinary users and the precise temperature control needs of professional users, making it more widely applicable.

[0017] 4. The overall structure is compact, maintaining the handheld use habit of portable fans, and intelligent temperature control can be achieved without changing the operation method. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to Figures 1-7. Example

[0020] As shown in Figures 1-7, a portable temperature-controlled fan with thermal imaging includes a handle 2 and a fan head 1. A battery 25 and a main control circuit board 24 are installed inside the handle 2. A drive motor 14 is installed inside the fan head 1. The output shaft of the drive motor 14 is connected to the fan blade main shaft 131. The fan blade 13 is fixed at the end of the fan blade main shaft 131.

[0021] The air outlet surface of the fan head 1 is side B, and side B has an air outlet. A thermal imaging lens 18 is installed on the side of the air outlet, and the detection direction of the thermal imaging lens 18 is consistent with the air outlet direction. The thermal imaging lens 18 and the drive motor 14 are both electrically connected to the main control circuit board 24 to form an automatic temperature control feedback loop.

[0022] A display screen 22 is mounted on side A of the handle 2. Side A faces opposite to side B. The orientation of the display screen 22 is opposite to the detection direction of the thermal imaging lens 18, making it convenient for the user to view when holding the handle.

[0023] Work process: The user holds the fan, pointing the air outlet (B) towards the target to be cooled; presses the power button 26, and the system starts; the main control circuit board 24 collects the thermal image and temperature data output by the thermal imaging lens 18 in real time, analyzes the target temperature, and automatically adjusts the speed of the drive motor 14 according to the preset temperature control strategy: the higher the temperature, the faster the speed and the greater the airflow; the lower the temperature, the slower the speed. The user observes the thermal image on the display screen 22 and adjusts the fan angle to center the target on the screen, achieving precise, non-contact, automatic cooling. Example

[0024] Based on Embodiment 1, a camera 17 is installed on side B of the fan head 1, next to the thermal imaging lens 18, with the camera 17 shooting in the same direction as the air outlet. The camera 17 is electrically connected to the main control circuit board 24.

[0025] The display modes of the screen 22 can be switched by operating button 27, including: pure thermal map mode, pure real-scene mode, and thermal map and real-scene fused screen mode. The fused screen can intuitively mark high-temperature areas, making it easy for ordinary users to quickly target and dissipate heat.

[0026] The remaining structures, connections, and working principles of this embodiment are the same as those of Embodiment 1.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any modifications, alterations, or equivalent changes made by those skilled in the art using the disclosed technical content without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
