Description

technical field [0001] The invention belongs to the field of respiratory protection devices, in particular to an electric air supply mask. Background technique [0002] In addition to the commonly used white multi-layer woven medical masks, the masks on the market are generally used in industrial and mining dust masks to seal the nose and mouth with a mask, and some have many ventilation holes on the shell. , Use polyurethane sponge and non-woven fabric (with static electricity) as the dust filter layer. This type of mask is called a simple dust mask, and the other type is equipped with an exhalation valve device on the shell. This type of mask is called a reciprocating anti-dust mask. dust mask. [0003] Multi-layer woven medical masks have poor sealing performance, and their dustproof effect is very poor; simple dust masks and reciprocating dust masks, due to the large cavity of the mask, the gas exhaled by people remains in it, and the inhalation effect is poor. When br...
