[0002] As people's awareness of security continues to deepen, security products such as security monitoring and alarm systems have been thoroughly integrated into our lives. Among them, surveillance cameras are widely used in residential areas, office buildings, streets, and indoor security. A typical CCTV system mainly consists of two parts: front-end equipment and back-end equipment. The front-end equipment usually consists of components such as cameras, manual or electric lenses, pan-tilt units, protective covers, listening devices, alarm detectors, and multi-functional decoders.

[0003] Most existing vehicle cameras experience large temperature fluctuations during operation, making them prone to fogging, especially during rainy seasons. Fog and frost are formed when saturated water vapor in the air condenses upon cooling. The strong and weak low temperatures result in condensation into frost and fog, respectively, which prevents the camera from capturing clear images of objects. Therefore, an anti-fog camera with a temperature control structure is proposed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution, including a U-shaped mounting bracket 1 and a camera body 3. A damping rotating ring 2 is connected to one side of the U-shaped mounting bracket 1. Rotating shafts 4 are connected to both sides of the camera body 3. The camera body 3 is rotatably positioned between the two sides of the U-shaped mounting bracket 1, and the rotating shaft 4 on the left side is rotatably positioned inside the damping rotating ring 2. A protective shell 5 is connected to the other side of the U-shaped mounting bracket 1. A motor 6 is connected inside the protective shell 5. The output end of the motor 6 is connected to the rotating shaft 4 on the right side. A data interface 7, a power connection 8, and a data card interface 9 are respectively connected to the upper half of one side of the camera body 3. A lens 10 is connected to the other side of the camera body 3. A connecting plate 11 is connected inside the camera body 3. Multiple heat dissipation slots 12 are opened on the upper and lower half of the surface of the connecting plate 11. A TEC semiconductor thermoelectric module 13 is connected to the central axis of one side of the connecting plate 11.

[0021] A heat sink 14 is connected to one side of the TEC semiconductor thermoelectric module 13, and two fans 15 are connected to one side of the camera body 3. The two fans 15 are distributed left and right. Their function is to quickly conduct heat generated by the TEC semiconductor thermoelectric module 13 during operation and dissipate it to the external environment through the synergistic effect of the heat sink 14 and the fans 15. This effectively prevents the normal operation of electronic components inside the camera body 3 from being affected by excessive temperature, and ensures the stability and reliability of the camera during long-term operation.

[0022] A humidity sensor 16 is connected to one side of the camera body 3 below the two fans 15, and the output end of the humidity sensor 16 extends into the camera body 3. Its function is to monitor the humidity inside the camera body 3 in real time. When the internal humidity exceeds the preset threshold, the corresponding anti-fog processing mechanism can be triggered in time. For example, the heating rod 18 is activated to heat the area around the lens 10 to prevent the lens 10 from fogging due to excessive humidity. This ensures that the camera can capture clear and accurate images under different environmental humidity conditions, improving the camera's adaptability and image quality in complex environments.

[0023] Two mounting slots 17 are provided on one side of the camera body 3, above and below the lens 10. Heating rods 18 are connected inside the mounting slots 17. Their function is to heat the area around the lens 10 when the ambient humidity is high or the lens surface temperature is low, raising the lens surface temperature and maintaining a relative balance between the lens surface temperature and the ambient temperature. This effectively prevents moisture from condensing on the lens surface, ensuring that the camera can continuously provide clear, unobstructed monitoring images even in humid environments, thus guaranteeing the normal operation of the monitoring system. At the same time, the reasonable arrangement of the heating rods 18 (two on each side) ensures more even heating, avoiding localized overheating or insufficient heating.

[0024] A transparent cover 19 is attached to one side of the camera body 3, covering the lens 10 and the heating rod 18. Multiple slots 20 are formed on the bottom inner side of the transparent cover 19. The transparent cover 19 provides effective physical protection for the lens 10 and heating rod 18 without affecting normal shooting, preventing damage from external dust, debris, and potential impacts, thus extending the lifespan of the device. The multiple slots 20 on the bottom inner side also facilitate air circulation, ensuring that the heat generated by the heating rod 18 during operation is dissipated smoothly to the area around the lens 10, while preventing heat accumulation due to the cover's closure. This maintains a suitable temperature environment inside the camera, further improving the stability and reliability of the device.

[0025] A spotlight 21 is connected to both sides of the lens 10 on one side of the camera body 3. Four mounting holes 22 are provided at the bottom of the U-shaped mounting bracket 1. The spotlights 21 provide auxiliary lighting for the camera in low-light environments, enhancing the brightness and clarity of the captured image. This allows the camera to capture clear and effective monitoring images even at night or in low-light conditions, expanding the camera's applicable scenarios and usage time. The four mounting holes 22 at the bottom of the U-shaped mounting bracket 1 facilitate the installation of the camera. These holes allow the camera to be securely mounted on various supporting surfaces such as walls and ceilings, ensuring the camera's stability and firmness after installation. This reduces potential shaking or displacement due to unstable installation, thus guaranteeing stable and accurate monitoring images.

[0026] Lens 10 is coated with a fluorinated polyethylene superhydrophobic film with a contact angle greater than 150 degrees. This film's function lies in its extremely low surface energy, making it difficult for water droplets to adhere to the lens surface. Instead, water droplets form near-spherical shapes and quickly roll off. This characteristic effectively prevents condensation and water droplet residue in humid, foggy, or even rainy environments, ensuring a clear field of view. Furthermore, the superhydrophobic film's contact angle greater than 150 degrees indicates exceptional hydrophobic properties; even if a small amount of water droplets comes into contact with the lens surface, they will slide off in a very short time, causing no interference to the captured image.

[0027] Working Principle: First, when the camera is in operation, the TEC semiconductor thermoelectric module 13 starts running. Based on the thermoelectric effect, a temperature difference is generated at its two ends. One end absorbs heat to cool key internal components of the camera, while the other end releases heat. The heat sink fins 14 are in close contact with the heat-releasing end of the TEC semiconductor thermoelectric module 13, rapidly conducting and diffusing the heat into the surrounding air. At this time, two fans 15 start, forming effective air convection by being distributed left and right, accelerating the airflow around the heat sink fins 14, thereby removing heat more quickly and ensuring that the TEC semiconductor thermoelectric module 13 can operate continuously and stably. This prevents the internal temperature of the camera from becoming too high due to heat accumulation, which could affect the performance of electronic components. Meanwhile, the humidity sensor 16 monitors the humidity inside the camera body 3 in real time. Once the internal humidity exceeds a preset threshold, it sends a signal to the control system. Upon receiving the signal, the control system immediately activates the heating rod 18 located in the mounting slot 17 above and below the lens 10. Heating rod 18 heats up the area around lens 10, raising the lens surface temperature and maintaining a relative balance with the ambient temperature. This prevents moisture from condensing and forming fog on the lens surface, ensuring clear imaging at all times. The fluorinated polyethylene superhydrophobic film coating on lens 10 further enhances the anti-fogging effect. Due to its extremely low surface energy and contact angle greater than 150 degrees, water droplets struggle to adhere to the lens surface, instead forming nearly spherical droplets that quickly roll off. Even in humid, foggy, or rainy conditions, the lens maintains a clear field of view. In low-light environments, searchlights 21 located on either side of lens 10 automatically activate, providing auxiliary illumination for the camera. The light emitted by searchlights 21 enhances the brightness and clarity of the captured image, enabling the camera to capture clear and effective surveillance images even at night or in low-light conditions. The entire camera is mounted using a U-shaped mounting bracket 1. Four mounting holes 22 at the bottom of the U-shaped bracket 1 facilitate stable mounting of the camera on various support surfaces such as walls and ceilings. After installation, the camera body 3 can rotate between the two sides of the U-shaped mounting bracket 1 via the two pivots 4. The pivot 4 on the left side can rotate inside the damping ring 2, while the motor 6 inside the protective shell 5 can drive the pivot 4 on the right side to rotate, thus enabling multi-angle adjustment of the camera body 3 to meet the needs of different monitoring scenarios. Through the coordinated work of these components, this anti-fog camera with a temperature control structure can operate stably in various complex environments, providing clear and accurate monitoring images.
