Abstract

The invention relates to a multifunctional mask with an independent channel. The mask can be provided with different accessories, can prevent viruses and bacteria in medical application and can also be used for atomization medicine absorption; the mask can prevent haze and poisonous gas in civil application and can also be used as an escape tool on a fire disaster scene under the special situation. According to the technical scheme, a silica gel material is adopted for preparation of a U-shaped double-layer sealing cover 1, multiple single air inlet valves 7 which can only conduct air inlet are formed on the inner wall of the double-layer cover, and the valves 7 are turned on during inspiration and turned off during expiration. Single air outlet valves 6 which can only conduct air outlet are formed on the U-shaped bottom, and the valves 6 are turned off during inspiration and turned on and independently communicated with the exterior during expiration. A cavity 2 between inner walls ofthe two layers is connected with the air inlet valves, and air inlets 3 can be connected with the related matched accessories.

Description

technical field [0001] The invention relates to a multifunctional mask with independent channels, which is especially suitable for medical anti-virus and anti-bacteria, and civil anti-fog and haze anti-toxic (harmful) gas. Background technique [0002] At present, ordinary masks still stay in the traditional mode, and technological transformation is also to improve and strengthen the protective function or the improvement is not thorough enough. Fundamental improvement is not carried out to its structure, and its basic principle is still the traditional common mode. The gas channel during exhalation and inhalation inside the mask is a mixed channel. Part of the gas is mixed in the mask or directly acts on the contact part of the mask. This may cause the virus and bacteria exhaled by the human body to enter the respiratory system again, and the water vapor in the exhaled gas will condense on the wall of the mask when it passes through the wall of the mask, causing the mask ...
