Description

Technical Field

[0001] The utility model relates to the technical field of breathing valves, in particular to a stable installation structure and a breathing valve. Background Art

[0002] The breathing valve can be installed on the mask to reduce the accumulation of hot and humid gas, lower the temperature inside the mask, and make breathing smoother and more comfortable. Ordinary masks have breathing problems after wearing because the 90 and 95 level masks are too airtight, and the wearing experience is bad. In order to take care of the weak, rhinitis and other respiratory diseases, the elderly and pregnant women, the added one-way air outlet valve allows the exhaust air to go out quickly, avoiding the wearer from repeatedly inhaling the exhaust gas they have exhausted, and optimizing the wearing experience.

[0003] The masks currently used with breathing valves are usually installed at the opening of the mask by snap-fitting the breathing valve and the corresponding valve cover. The main fixing structure is the cylindrical protrusion structure on the top of the breathing valve and the hollow cylindrical protrusion structure at the bottom of the valve cover. After installation, it is easy to be squeezed and collided and it is easy to be separated from the original position, affecting the use of the mask. For this reason, we propose a stable installation structure and a breathing valve. Utility Model Content

[0006] Preferably, the first stopper and the second stopper have the same structural size and are symmetrically arranged with respect to the protective housing, and the height of the plane where the top of the first stopper is located is lower than the height of the plane where the bottom of the second stopper is located.

[0007] Preferably, the cross-sectional area of ​​the baffle is larger than the cross-sectional area of ​​the protective shell, a shielding ring is provided at the bottom of the baffle, and the baffle is configured as an arc-shaped structure with a recessed interior.

[0008] A breathing valve comprises a breathing valve, wherein a silicone gasket is arranged on the outside of the breathing valve, a valve cover is installed on the outside of the breathing valve, the protective shell is fixedly connected to the outside of the breathing valve, a columnar protrusion is arranged on the top of the breathing valve, and a hollow columnar protrusion is arranged on the bottom of the valve cover.

[0010] Preferably, the first trough bodies and the second trough bodies are provided in two groups, wherein the length of one group of first trough bodies is greater than the length of the other group of first trough bodies, and the heights of the two second trough bodies are unequal.

[0011] Beneficial effects:

[0012] 1. The stable installation structure and the breathing valve, after the column protrusion provided by the breathing valve is inserted into the hollow column structure provided by the valve cover, the first stopper and the second stopper can be slidably connected to the inside of the two first grooves, and the first stopper and the second stopper are changed to the inside of the second groove by controlling the rotation of the valve cover, and the first stopper and the second stopper push the elastic sheet to deform and move to the other side of the elastic sheet by applying a rotational force, and then snap into the tail of the second groove. After installation, the valve cover and the breathing valve can be in a stable connection state, and the provided sealing ring is squeezed, which can increase the sealing between the mask body and the breathing valve.

[0013] 2. The stable installation structure and the breathing valve fix the baffle to the top of the valve cover through a connecting rod, which can cover the air holes on the top of the valve cover to prevent the air holes from being exposed to the outside of the mask, and prevent other people from visually seeing the air holes and guessing that the mask is leaking, thereby increasing the aesthetics.
