Description

Waterproof housing structure and lighting equipment Technical Field The utility model relates to the technical field of lamps, in particular to a waterproof shell structure and lighting equipment. Background The lamp generally has a waterproof function, the temperature in the cavity of the lamp is generally higher than 60 ℃ under the working state, the lamp is reduced from 60 ℃ to below 30 ℃ in a short time under the condition of outdoor sudden rainfall and temperature reduction, and larger negative pressure can be produced in the cavity of the lamp to suck external rainwater into the cavity so as to destroy internal electronic components. The current lamp on the market is provided with a breathing ventilation valve, so that external gas can be pumped into the cavity to balance the air pressure when negative pressure is generated in the cavity. However, in rainy and foggy weather, rainwater is easy to block the breathing ventilation valve, so that air cannot be normally inhaled, and outside moist air is easy to invade the cavity from other waterproof weak points of the lamp. Disclosure of utility model In order to overcome the defects of the prior art, the utility model aims to provide a waterproof shell structure and lighting equipment so as to solve the problem that the current lamp is invaded by water vapor when a breathing ventilation valve is blocked. The utility model adopts the following technical scheme: a waterproof shell structure comprises a shell and a gas storage device; The shell is provided with a cavity, the shell is provided with a first ventilation hole which communicates the cavity with the outside, and the first ventilation hole cover is provided with a waterproof ventilation film; The air storage device is arranged on the shell and is provided with an air chamber communicated with the outside, and the air chamber sucks the outside air when the cavity generates negative pressure so as to increase the volume of the air storage device in the cavity. Preferably, the device further comprises a mounting component, wherein the shell is provided with a mounting hole, and the mounting component is penetrated through the mounting hole; the installation component is equipped with the parallel setting and all communicate in installation cavity and the air guide groove of cavity, gas storage device locates the installation cavity, the one end of air guide groove communicates in seting up on the installation component first bleeder vent. Preferably, the gas storage device is an air bag having elasticity. Preferably, the opening cover of the air chamber is provided with a cover plate, and the cover plate is provided with a second ventilation hole communicated with the air chamber. Preferably, the mounting component is provided with a second mounting cavity, the mounting cavity penetrates through the bottom wall of the second mounting cavity, and the cover plate is detachably embedded in the second mounting cavity. Preferably, the waterproof and breathable air guide device further comprises a limiting part, wherein the mounting part is provided with a first mounting concave cavity, one end of the air guide groove penetrates through the bottom wall of the first mounting concave cavity, the limiting part is detachably embedded in the first mounting concave cavity, and the waterproof and breathable film is located between the limiting part and the bottom wall of the first mounting concave cavity. Preferably, the installation component is equipped with the extension, be equipped with in the extension installation cavity with the air duct, the cover is equipped with the sealing washer on the extension, one of them terminal surface butt of sealing washer in the terminal surface of installation component.
