Waterproof breathable respirator and lamp provide with same

Abstract

The invention provides a waterproof breathable respirator and a lamp. The waterproof breathable respirator comprises a shell body with an accommodating cavity and a hollow pipe; a breather hole is arranged at the bottom part of the shell body; the hollow pipe extends into the accommodating cavity from the bottom part of the shell body; the top part of the hollow pipe is pressed against a cavity wall at the top part of the accommodating cavity; and through holes communicated with the accommodating cavity are arranged at the middle part of the hollow pipe. When the waterproof breathable respirator is applied to the lamp, the air inside the lamp enters the accommodating cavity through the hollow pipe and is exchanged with outside air through the breather hole; and meanwhile, as for the through holes by which the hollow pipe is communicated with the accommodating cavity, as the middle position in the hollow pipe is higher than the breather hole, condensed water vapor entering the accommodating cavity from the breather hole still flows out from the breather hole and can not enter the hollow pipe from the through holes so as to prevent the water vapor from entering the lamp to affect the performance of the lamp. With the adoption of the simple structure, the waterproof breathable respirator realizes the effects of watertightness and ventilation, has low cost and is suitable for widepopularization and use.

Description

technical field [0001] The invention relates to a waterproof and breathable device, more specifically, to a waterproof and breathable respirator and a lamp equipped with the waterproof and breathable respirator. Background technique [0002] At present, in daily life, industrial and professional products, there are often high requirements on the waterproof, dustproof, heat dissipation and ventilation of the products. For example, some outdoor lighting fixtures need to be sealed to achieve a certain level of protection. When these lighting fixtures work, the light source generates heat intensively, forming a high-temperature space in the lamp body, and the air in the lamp body expands in the high-temperature space, so that the pressure inside the lamp is higher than that of the outside of the lamp, so that the gas will be released from the sealed gap of the lamp. It leaks into the outside air, so that the pressure inside the lamp is balanced with the outside atmospheric pres...

Problems solved by technology

At present, most waterproof respirators on the market use activated carbon to absorb water vapor, but activated carbon is expensive and prone to clogging, so it is not suitable for widespread use
