Face mask and air leak real-time detection method

Abstract

The invention discloses a face mask and leakage detecting method of face mask, which contains lid, wherein the mask possesses head coil or ear coil, which contains at least one fixed or replaced filtering device, the mask is composed of inner mask and transparent periphery around the inner mask, the filtering device is placed on the inner mask, the transparent periphery attaches the user face, which forms sealing edge with entire mask, the fine frosted pit is formed on the inner side of transparent peripheral back with external side as smooth surface or the back possesses real-time variation displayed covering layer. The invention can display connecting degree between mask and face, which monitors leakage condition effectively.

Description

【Technical field】

[0001] The invention relates to a face mask, in particular to a face mask capable of judging air leakage in real time by naked eyes and an air leakage detection method thereof. 【Background technique】

[0002] People sometimes need to work in places with serious air pollution, such as dusty environment or activities in places subject to biochemical pollution. In order to ensure people's normal breathing, people generally need to wear a breathing device or a face mask when working in an environment where the air is polluted, which has prevented people from inhaling polluted air and causing accidents such as poisoning.

[0003] An effective mask or breathing apparatus must meet two basic conditions. One is that the filter medium must effectively remove harmful particles in the air and allow air to pass through; the other is that the mask or breathing device must fully fit the user's face so that harmful particles can bypass the filter medium and enter the use...
