The function of sanitary breathing valve

The breathing valve controls the exhaled airflow by opening and closing the valve so that it is discharged from the outside of the mask. It consists of several parts, including valve body, valve plate, top column, spring, sealing device, etc. When people breathe, the exhaled air flows through the valve piece, causing it to open and be discharged from the valve body. The valve piece will close independently when breathing is adjusted to prevent air from flowing back. When choosing a mask, you should pay attention to choosing a mask with a breathing valve. Although the breathing valve can provide a better breathing experience, it will also weaken the filtering efficiency of the mask. Therefore, some masks with breathing valves are not suitable in some places where the spread of the virus is strictly prohibited or where there is a high risk of infection (such as medical institutions, etc.). In other low-risk places, such as research laboratories, offices, construction sites, etc., masks with breathing valves can filter dust, smoke and other harmful substances while also providing a comfortable breathing experience. The main functions of the sanitary breathing valve are: 1. Filter harmful substances in the air (the built-in filter element of the sanitary breathing valve can filter harmful substances in the air, such as rust, dust, liquid spray, odor, etc., thereby preventing these substances from entering the respiratory organs and protecting Respiratory organ health.) 2. Reduce breathing resistance (when performing high-intensity exercise, each breath requires a large amount of energy, and the sanitary breathing valve can reduce breathing resistance, making it easier for people to breathe during exercise, thereby maintaining the body's Good condition.) 3. Avoid fogging of glasses (while wearing a mask, glasses often fog up, affecting vision. The outlet of the hygienic breathing valve can discharge hot exhaled air out of the mask, effectively avoiding the problem of glasses fogging. ) Whether in the medical industry or industrial and civil fields, the principle of adding breathing valves to masks will continue to be applied. The breathing valve will serve as a protective tool, which always plays an important role in improving production efficiency and protecting the environment, making us safer and healthier.
