Description

Tubular breather valve and mask

Technical Field

The utility model relates to a respiratory protection field, in particular to tubular breather valve and gauze mask.

Background

The breather valve that the orofacial mask in the present market was used, the plane film piece that possesses certain elasticity that makes with silica gel etc. comes as exhaling the actuation valve block, nevertheless has a plurality of problems:

1. the self weight of the membrane valve plate can not ensure that the membrane valve plate is always in a closed state, particularly when the respirator is worn and the head-down breather valve is in a downward state, the membrane is likely to generate a gap due to the self weight, and is more likely to be instantly closed due to insufficient suction at the beginning of inspiration after expiration, and is likely to generate a gap when the membrane is clamped by fine particles, and harmful substances, particularly tiny viruses can enter the gap and the gap which are not closed in time;

2. considering the self weight of the diaphragm, the large breather valve cannot be used for increasing the space of the exhalation passage and the exhalation volume, and the breathing valve with the structure is limited to small size and limits the exhalation volume because the diaphragm is heavy after being large in size, so that the suction is more difficult to perform, the suction distance is also increased, and the suction closing time is also prolonged;

3. some mask production units consider that the existence of a possible gap and the attraction delay cause unsafety, the breather valve is arranged on the outermost layer cloth of the mask three-layer filter cloth, the safety is improved through the inner two-layer filtering, but the breathing valve exhaust function is greatly reduced, the breather valve exhaust function is almost equivalent to a mask without the breather valve, the exhaled damp and hot air enables the inner two layers to be damp, particularly the middle most important filter layer is enabled to be damp and lose static electricity, the protection effect is reduced, the breathing resistance is increased, and bacteria can also multiply.
