AI Technical Summary
In harsh environments, the breathable membrane of the breathing apparatus of industrial and mining lamps is prone to blockage, which leads to an imbalance of internal and external air pressure, resulting in damage to the seals or deformation of the lamp.
A heating jacket is installed on the outside of the respirator. The air entering the breathing hole is heated by the heating wire inside the jacket, which prevents water vapor from condensing into water droplets and clogging the breathable membrane.
It effectively prevents the breathable membrane from clogging, maintains the air pressure balance inside and outside the industrial and mining lamp, and avoids damage to the seals and deformation of the lamp.

[0042] It is found through research that the prior art has the following disadvantages: In order to prevent the invasion of dust, salt mist and other corrosive substances, the industrial and mining lamp often needs a sealed lampshade to prevent dust and water molecules from entering the inside of the lamp, and the sealed lampshade needs a breather to balance the pressure inside and outside the lampshade, thereby prolonging the service life of the lamp. However, in some relatively harsh environments, such as in a high humidity environment, water vapor in the air is easy to condense into water droplets on the surface of the breathable film of the breather, causing the micropores of the breathable film to be blocked, thereby causing the air pressure inside and outside the industrial and mining lamp to be unable to balance. When the temperature changes, negative pressure or positive pressure may be generated inside the industrial and mining lamp, causing the sealing element to be damaged or the lamp to be deformed.
[0043] Based on the above research, the present embodiment provides an industrial and mining lamp, which is provided with a heating sleeve outside the breather of the industrial and mining lamp, so as to prevent water vapor in the air from condensing into water droplets to block the breathable film of the breather, thereby solving the above problems.
