[0002] The temperature inside the medical freezer case can be as low as -50 degrees Celsius, and the general working temperature is also around -20 degrees Celsius. In order to observe the operating status inside the case in real time, a camera can be installed inside the freezer case. However, if the camera is installed directly, the camera will not work properly due to the low temperature environment of -20 degrees Celsius to -50 degrees Celsius. The Chinese patent with the current publication (announcement) number CN220421929U discloses an anti-fog camera, including a lens housing, a lens, a lens seat, a drying and ventilation mechanism, a sealing mechanism and a lens heating mechanism. The lens and the lens heating mechanism are both arranged inside the lens housing. The sealing mechanism connects and seals the lens seat with the lens housing. The drying and ventilation mechanism is arranged on the lens seat. The drying and ventilation mechanism includes a dryer, an air dryer, an air suction port, an exhaust duct, an air outlet and a suction fan. The sealing mechanism includes a sealing ring, a rubber sealing pad, a fixing bolt and a fixing hole.

[0003] Although the above-mentioned anti-fog camera, through the setting of the lens heating mechanism, is conducive to drying the part of the space in contact with the lens, which is convenient for the device to be used in a high humidity environment, and through the setting of the sealing mechanism, it is conducive to preventing dust from entering the camera, improving the sealing function of the device, and exhausting the water vapor to the outside through the exhaust pipe through the suction fan, it is prevented that the water vapor re-aggregates into fog and finally affects the function of photography. After actual use, when the above-mentioned anti-fog camera is installed in the case of a medical freezer at -20℃ to -50℃, it is found that it is easy to have abnormalities, affecting normal use.
