[0021] 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.

[0022] Please see Figure 1-4 As shown, an endoscope camera system defogging detection device includes a humid heat chamber 2, which has a cylindrical structure with one end sealed and the other end open. A heat-conducting plate 10 is provided on the inner wall of the humid heat chamber 2, and an electric heating coil 4 is embedded in the outer wall of the heat-conducting plate 10. A highly absorbent resin 12 is installed on the inner wall of the heat-conducting plate 10. A piston plate 6 is slidably installed inside the humid heat chamber 2, and a universal ball 7 is rotatably installed on the piston plate 6. The universal ball 7 has an insertion hole for the endoscope to pass through.

[0023] Specifically, the humid heat chamber 2 serves as the core space for testing, with one end sealed and the other open. A heat-conducting plate 10 is installed on the inner wall of the humid heat chamber 2, and an electric heating coil 4 is embedded in the outer wall of the heat-conducting plate 10. When energized, the electric heating coil 4 generates heat, which is conducted through the heat-conducting plate 10. The highly absorbent resin 12 on the inner wall of the heat-conducting plate 10 absorbs moisture, which evaporates under the heat conducted by the heat-conducting plate 10, generating water vapor and thus creating a misty environment inside the humid heat chamber 2. Piston plate 6 slides and seals inside the humid heat chamber 2, pushing the internal gas and water vapor to adjust the pressure and fog concentration within the chamber. Universal ball 7 is rotatably mounted on piston plate 6. The endoscope passes through an insertion hole inside universal ball 7 into the humid heat chamber 2. Universal ball 7 can flexibly adjust the angle and position of the endoscope. Through the cooperation of electric heating coil 4, heat-conducting plate 10, and highly absorbent resin 12, the generation of water vapor can be precisely controlled. Compared to the traditional method of bringing high-temperature water vapor close to the endoscope, this method can stably control the degree and uniformity of fogging at the endoscope tip, improving the consistency and comparability of test results. The arrangement of piston plate 6 and universal ball 7 facilitates adjustment of the testing environment and endoscope position, making testing more flexible and comprehensive, and contributing to an objective and accurate evaluation of the defogging function of the endoscope imaging system.

[0024] As a technical optimization of this utility model, a spiral groove 11 is provided on the outer wall of the heat-conducting plate 10, and the electric heating coil 4 is embedded in the spiral groove 11.

[0025] Specifically, the spiral groove 11 on the outer wall of the heat-conducting plate 10 allows the heating coil 4 to be evenly distributed along the spiral path after being embedded therein. When energized, the heat generated by the heating coil 4 is evenly conducted to the heat-conducting plate 10 along the spiral path, thereby causing the heat-conducting plate 10 to heat up evenly and uniformly heat the superabsorbent resin 12. The cooperation between the spiral groove 11 and the heating coil 4 ensures that the heat-conducting plate 10 is heated evenly, avoiding local overheating or undercooling, thereby causing the superabsorbent resin 12 to evaporate evenly to produce water vapor, further improving the uniformity of fog in the humid heat chamber 2, improving the reliability and accuracy of the test results, and overcoming the problem of uneven fogging in traditional test methods.

[0026] As a technical optimization of this utility model, the outer wall of the humid heat chamber 2 is provided with a control panel 3, which is electrically connected to the heating coil 4.

[0027] Specifically, the control panel 3 on the outer wall of the humid heat chamber 2 is electrically connected to the heating coil 4. Operators can control the on / off state of the heating coil 4 and adjust its power through the control panel 3. When it is necessary to increase or decrease the amount of water vapor generated, the working state of the heating coil 4 is adjusted through the control panel 3, thereby controlling the temperature of the heat conduction plate 10, and thus controlling the evaporation rate and amount of water vapor generated by the superabsorbent resin 12. The control panel 3 enables convenient control of the water vapor generation process. Operators can flexibly adjust the fog concentration in the detection environment according to the detection requirements. Compared with the traditional method that cannot accurately control the amount of water vapor generated, it can more accurately simulate different fogging scenarios, making the detection more in line with actual use and improving the effectiveness and relevance of the detection.

[0028] As a technical optimization of this utility model, a temperature sensor 14 is installed inside the humid heat chamber 2, and the temperature sensor 14 is electrically connected to the control panel 3.

[0029] Specifically, a temperature sensor 14 installed inside the humid heat chamber 2 monitors the temperature inside the chamber in real time and converts the temperature data into an electrical signal, which is then transmitted to the control panel 3. The control panel 3 adjusts the heating coil 4 according to a preset temperature range. When the temperature is below the preset value, the control panel 3 increases the power of the heating coil 4; when the temperature is above the preset value, it decreases the power of the heating coil 4, thereby maintaining a stable temperature inside the humid heat chamber 2. The cooperation between the temperature sensor 14 and the control panel 3 achieves precise temperature control inside the humid heat chamber 2, ensuring that the superabsorbent resin 12 evaporates under a stable temperature environment, resulting in stable water vapor production and avoiding unstable fogging caused by temperature fluctuations. This further improves the consistency and reliability of the test results, solving the problem of uncontrollable temperature affecting test results in traditional testing methods.

[0030] As a technical optimization of this utility model, the end cap of the humid heat chamber 2 is provided with a viewing window 5, and transparent tempered glass is embedded inside the viewing window 5.

[0031] Specifically, the viewing window 5 at the sealed end of the humid heat chamber 2 has a transparent tempered glass embedded inside. During the testing process, the operator can directly observe the imaging of the endoscope inside the humid heat chamber 2 through the viewing window 5 without opening the chamber, thus not affecting the internal fog environment. The viewing window 5 allows the operator to observe the imaging effect of the endoscope camera system in a foggy environment in real time, promptly judge the quality of the defogging function, and avoid disrupting the internal testing environment by frequently opening the humid heat chamber 2, ensuring the continuity of the testing process and the accuracy of the test results. Compared with traditional testing methods, it provides a more convenient observation method.

[0032] As a technical optimization of this utility model, a base plate 1 is installed on the outer wall of the humid heat chamber 2, and mounting holes are provided on the base plate 1.

[0033] Specifically, mounting holes are provided on the base plate 1 installed on the outer wall of the humid heat chamber 2. By passing bolts or other connecting parts through the mounting holes, the entire endoscope camera system defogging detection device can be fixedly installed on the testing table or other suitable positions to ensure that the device remains stable during the testing process. The design of the base plate 1 and the mounting holes makes the device easy to install and fix, improves the stability and safety of the device, avoids the impact of device shaking on the test results, and facilitates the installation and use of the device in different testing sites, thus enhancing the applicability of the device.

[0034] As a technical optimization of this utility model, a waterproof and breathable membrane is provided on the inner wall of the heat-conducting plate 10, and a filling cavity is formed between the waterproof and breathable membrane and the inner wall of the heat-conducting plate 10, and the highly absorbent resin 12 is filled inside the filling cavity.

[0035] Specifically, a waterproof and breathable membrane is provided on the inner wall of the heat-conducting plate 10, forming a filling cavity with the inner wall of the heat-conducting plate 10, which is filled with superabsorbent resin 12. The waterproof and breathable membrane allows water vapor to pass through while preventing moisture in the superabsorbent resin 12 from directly leaking between the heat-conducting plate 10 and the inner wall of the humidification chamber 2, ensuring that the superabsorbent resin 12 works stably in the filling cavity. The waterproof and breathable membrane and the filling cavity ensure that the water vapor generated by the superabsorbent resin 12 can smoothly enter the humidification chamber 2 to form mist, and prevent moisture leakage from the superabsorbent resin 12 from affecting the normal operation of other components of the device, extending the service life of the device, improving the stability and reliability of the device, and avoiding detection errors or device malfunctions caused by moisture leakage.

[0036] As a technical optimization of this utility model, a sealing membrane 15 is installed inside the insertion hole of the universal ball 7, and a sealing cavity 13 is formed between the inner wall of the insertion hole and the outer wall of the sealing membrane 15. An inflation tube 8 is provided on the outer wall of the universal ball 7. One end of the inflation tube 8 extends into the sealing cavity 13 and communicates with the sealing cavity 13, and the other end extends to the outside of the universal ball 7 and is threadedly connected to a plug 9.

[0037] Specifically, the sealing membrane 15 installed inside the insertion hole of the universal ball 7 forms a sealing cavity 13 with the inner wall of the insertion hole. One end of the inflation tube 8 is connected to the sealing cavity 13, and the other end extends to the outside of the universal ball 7. When the endoscope passes through the insertion hole, air is inflated into the sealing cavity 13 through the inflation tube 8, causing the sealing membrane 15 to expand and tightly adhere to the outer wall of the endoscope, thus achieving a seal. After the inspection is completed, the plug 9 is unscrewed to release the air, and the endoscope can be removed. The cooperation of the sealing membrane 15, the sealing cavity 13, and the inflation tube 8 ensures the sealing of the humid heat chamber 2 when the endoscope passes through the universal ball 7, preventing internal water vapor leakage from affecting the inspection environment. At the same time, it facilitates the installation and removal of the endoscope, improves inspection efficiency, and the sealing effect can be flexibly adjusted by the inflation degree, making it suitable for endoscopes of different specifications and enhancing the versatility and practicality of the device.

[0038] Working Principle: This endoscopic camera system's defogging detection device uses the humid heat chamber 2 as its core detection space. Through the coordinated operation of multiple components, it simulates a foggy environment and achieves accurate detection. First, the heating coil 4 is embedded in the spiral groove 11 on the outer wall of the heat-conducting plate 10. After being energized, it heats up evenly along the spiral path, and the heat is conducted to the inner wall through the heat-conducting plate 10. The highly absorbent resin 12, filled in the cavity of the inner wall of the heat-conducting plate 10, absorbs moisture and evaporates evenly under stable heat, generating stable and uniform water vapor within the humid heat chamber 2, thus creating a foggy environment.

[0039] The operator controls the working status of the heating coil 4 through the control panel 3, and can flexibly adjust the temperature of the heat conduction plate 10, thereby precisely controlling the evaporation rate and water vapor generation of the superabsorbent resin 12. At the same time, the temperature sensor 14 monitors the temperature inside the humid heat chamber 2 in real time and feeds the data back to the control panel 3 to achieve closed-loop temperature control and ensure the stability of the water vapor generation process.

[0040] During testing, the endoscope passes through the insertion hole of the universal ball joint 7 into the humid heat chamber 2. The universal ball joint 7 can flexibly adjust the angle and position of the endoscope to meet different testing needs. After insertion, air is injected into the sealing cavity 13 through the air inflator 8, causing the sealing membrane 15 to expand and adhere to the outer wall of the endoscope, ensuring the airtightness of the humid heat chamber 2. The piston plate 6 slides within the humid heat chamber 2, pushing the internal gas and water vapor to regulate the pressure and fog concentration within the chamber. The operator observes the imaging of the endoscope in the foggy environment through the viewing window 5 to judge the quality of its defogging function. The entire device is fixed to the testing stage through the mounting holes on the base plate 1 to ensure stable testing.
