A mask with a service life reminder function

Abstract

The invention relates to a mask with a service life reminder function, comprising a mask body with a plurality of filter layers, a reminder device is arranged between the filter layers of the mask body, and the reminder device has a filter protruding from the outermost side of the mask body. The identification unit of the first layer and the elastic component that can make the identification unit send identification information, so that the service life of the mask can be judged by the identification unit.

Description

technical field [0001] The invention relates to the field of human health, in particular to a mask with a service life prompt function. Background technique [0002] The rapid development of the national economy and the continuous consumption of energy have also brought about increasingly serious environmental pollution, making masks an indispensable item for people to travel. Masks can effectively filter out pollutants in the atmosphere, protect people's health, and reduce respiratory diseases. [0003] However, there is no uniform standard for current masks, especially civilian masks. Most of them do not have a clear expiration date. Use it, and replace it when the date arrives, which will cause waste. Moreover, different people have different breathing rates. Even if the wearing time is the same, the pollutants adsorbed by the mask may be different. Therefore, it is not very scientific to determine the life of the mask according to the opening time or use time. [0004...
