Mask and gas buffer oxygen producing device available for same

Abstract

The invention provides a gas buffer oxygen producing device available for a mask. The gas buffer oxygen producing device comprises an oxygen producing material filling layer, a separable oxygen producing material protecting layer, a gas buffer layer, a fixed connecting device and an outer protecting layer, wherein the oxygen producing material filling layer is used for filling materials capable of generating oxygen through reaction, the separable oxygen producing material protecting layer is used for protecting the oxygen producing materials before use and enabling the oxygen producing materials to react after separation to generate oxygen, the gas buffer layer capable of forming a gas storage space is arranged on the other side opposite to the oxygen producing material protecting layer and used for temporarily storing gas to avoid unsmooth inhalation caused by negative gas pressure formed in the mask in inhalation, the fixed connecting device is used for fixedly connecting the gas buffer oxygen producing device with the mask, and the outer protecting layer is opposite to the fixed connecting device and can protect the fixed connecting device in a state to be used. By the device, a mask wearer can keep smooth breath while realizing effective filtering.

Description

technical field [0001] The invention relates to a gas buffer oxygen generating device which can be used for a mask and a mask with the device attached. Background technique [0002] Dust, bacteria, smog and other harmful substances in the air have caused great harm to human health. Recently, a research report jointly published by professors from the Massachusetts Institute of Technology (MIT), Tsinghua University and Peking University in Beijing, and the Hebrew University of Jerusalem estimated that air pollution in North China has In the 1990s, a total of 2.5 billion years of human life expectancy was reduced, the incidence of lung cancer, heart disease and stroke was increased, and the life expectancy of residents in northern China was reduced by 5.5 years. Before the air pollution problem cannot be solved quickly, people usually wear masks to reduce their own damage when engaging in outdoor activities. For example, people usually use N95 masks that can block more than 9...

AI Technical Summary

Problems solved by technology

However, the structure of the masks in these schemes is relatively complicated, the cost is high, the use is not convenient, and it cannot be used in combination with existing masks, so there is a lot of room for improvement
