Embodiment 1

[0040] Reference manual attached Figure 1 to Figure 4 , the airway waterproof structure provided by the present invention is described, the airway waterproof structure can reduce or prevent the entry of external liquid while ensuring that the gas can be discharged through the airway inlet or outlet, so as to effectively protect the equipment or system Protect.

[0041] Reference manual attached figure 1 and figure 2 , specifically, the airway waterproof structure includes: a waterproof structure frame 1 and a water retaining plate 2 . The waterproof structure frame 1 surrounds and forms a ventilation area 10; the water retaining plate 2 is installed on the waterproof structure frame 1, and the front projection of the water retaining plate 2 covers the surrounding area formed by the waterproof structure frame 1. In the ventilation area 10, a gas passage 3 is formed around the water baffle 2 and the structural frame 1 or between adjacent water baffles.

[0042] It should b...

Embodiment 2

[0058] Reference manual attached Figure 1 to Figure 4 , the pressure relief valve provided by the present invention is described, the pressure relief valve includes a pressure relief valve body 4 and the airway waterproof structure described in the above-mentioned embodiment 1, and the airway waterproof structure is installed on the pressure relief valve body vents. The airway waterproof structure can allow the gas in the pressure relief valve to be discharged to the outside while reducing or avoiding the entry of outside air.

[0059] Reference manual attached figure 1 and figure 2 , preferably, the waterproof structure frame 1 of the airway waterproof structure is installed on the pressure relief valve body 4 through a fastening connection. Optionally, in other preferred embodiments of the present invention, the waterproof structure frame 1 of the airway waterproof structure can also be installed on the pressure relief valve body 4 in other ways, and the airway is water...

Abstract

The invention discloses an airway waterproof structure, a pressure release valve and a vehicle. The airway waterproof structure comprises a waterproof structure frame body which forms a ventilation area in a surrounding manner, and water baffles; and the water baffles are installed on the waterproof structure frame body, the front projections of the water baffles cover the ventilation area formed by the waterproof structure frame body in a surrounding mode, and gas channels are formed between the water baffles and the structure frame body or between the adjacent water baffles in a surrounding mode. According to the airway waterproof structure, gas can be ensured to be discharged through the inlet or the outlet of the airway, and meanwhile, entering of external liquid can be reduced or prevented, so that equipment or a system can be effectively protected.

Description

technical field [0001] The invention relates to the field of waterproof structures, and further relates to an airway waterproof structure, a pressure relief valve and a vehicle. Background technique [0002] In daily life, we often encounter scenes that require gas to pass through but not liquid to pass through. For example, but not limited to, the pressure relief valve air inlet of vehicles, air conditioner air inlets, fresh air mechanism air inlets, and ventilation places of buildings, etc. need to be waterproof and breathable In these scenarios, the equipment needs to be ventilated, but the entry of liquid will cause fatal damage to the equipment or system. [0003] For example, the pressure relief valve of a vehicle is a crucial component of the vehicle, also known as a safety valve, which can effectively open and close automatically according to the working pressure of the system, and is generally mainly installed in a closed system Or on the pipeline, the safety of th...
