Detailed Description

The automatic breather valve can be made of the following materials, and is not limited to the following materials, for example: plastic, aluminum alloy, stainless steel, tetrafluoroethylene, polycarbonate, rubber, plastic, filter fiber, spray-melt fiber, silicone sheet, spring, metal, and the like.

Fig. 1 is a side view of an automatic breather valve according to an embodiment of the present invention; the breather valve of the present embodiment is intended to be mounted on a breathing mask or breathing-related respirator, respirator or gas mask.

The utility model discloses automatic breather valve includes: a valve body 1 and a filter cover 3; the valve body 1 is of a tubular structure with two open ends; the openings at the two ends are communicated with each other. The filter mantle 3 is a closed cavity with an opening at one end, and the filter mantle 3 is arranged on the valve body 1 through the opening of the filter mantle 3.

One end of the valve body 1 is provided with a port 2, and the other end of the valve body is connected with the filter cover 3; the filter screen 30 is wrapped on the filter cover 3; the filter screen 30 is used for filtering the air entering the filter housing 3 and filtering harmful substances and foreign matters in the air.

That is, the filter housing 3 communicates with the mouthpiece 2 through the valve body 1; typically, the interface 2 is provided with a threaded connection 20. The threaded connector 20 can be connected with an external mask, a mouth mask, a respirator or a gas mask, and the breathing effect can be realized as long as the threaded connector is communicated with the mouth and the nose of a human body.

The side of the valve body 1 is provided with at least one exhaust cavity 14 for exhausting air exhaled by a human body.

A valve plate 4 for opening or closing the exhaust cavity 14 is arranged in the exhaust cavity 14; the valve plate 4 is provided with a return spring 40, and the valve plate 4 is installed in the exhaust cavity 14 through the return spring 40.

In the actual use process, the connector introduces exhaled air, the air pressure in the valve body is increased, the valve plate 4 is jacked open, the valve plate 4 moves outwards, the exhaust cavity 14 is opened, and exhaled waste gas is exhausted.

In the air suction process, the air pressure in the valve body 1 is reduced, so that the valve plate 4 automatically closes the exhaust cavity 14 under the action of the return spring; then the air enters the filter cover through the filter screen 30 on the filter cover 3, and finally is inhaled by the human body through the valve body 1. In the process of inspiration, because the negative pressure acts on the valve plate 4 firstly, the air exhaust cavity is closed and then filtered air is inhaled, and the whole breather valve acts quickly and is not easy to leak.

The automatic breather valve of the embodiment, wherein, the bottom of the exhaust cavity 14 is provided with a partition plate, and the partition plate is provided with an exhaust hole 11; the exhaust hole 11 is opposite to the valve plate 4.

The valve plate 4 is installed on the partition plate through the return spring 40, and the exhaust hole 11 corresponds to the valve plate 4.

Therefore, when the air exhales, the air pushes the valve plate 4 open through the air exhaust hole 11 to exhaust; when breathing, the return spring automatically pulls the valve plate into the exhaust cavity, so that the aim of isolating the exhaust cavity is fulfilled. Moreover, when the air pressure in the valve body 1 is lower than the resilience force of the return spring, the valve plate can be closed, and the whole valve plate is only opened when the air pressure in the expiration is higher, so that the airtightness is better, and the leakage is not easy to occur.

Preferably, two exhaust cavities 14 are symmetrically arranged on two sides of the valve body 1; the valve plate 4 is of a piston structure, and the valve plate 4 moves in the exhaust cavity 14 in a reciprocating mode to open or close the exhaust hole 11.

In the automatic breathing valve of the present embodiment, a metal grid mesh 10 is further disposed between the valve body 1 and the filter housing 3. The metal grid mesh 10 can cool the exhaled air, so that the air is condensed at the place, and the phenomenon that water drops are blocked near the exhaust cavity to pollute the exhaust cavity is avoided.

In the automatic breather valve of the present embodiment, the filter housing 3 is a cylindrical structure, and the filter screen 30 is wrapped on the outer layer of the filter housing 3; the filter housing 3 may also be spherical or conical.

The outer side of the filter screen 30 is further provided with a fixing cover 31, and the fixing cover 31 is of a net structure. The filter screen 30 is pressed against the filter housing 3 by the fixing housing 31.

When in use, the filter screen 30 on the filter cover 3 can be replaced by taking off the fixed cover 31.

Additionally, the utility model discloses an automatic breather valve cost of manufacture is not high, and is small and exquisite, and structural design is compact, and finished product quality is stable, and the gas tightness is strong, dresses the convenience, is applicable to various gauze masks, respirator, gas mask, dust mask, breathing machine etc..
