Abstract

La présente invention concerne un masque respiratoire, comprenant un corps de masque (6), un couvercle, un sac filtrant (7) et un sac filtrant de source d'alimentation (8). Le corps de masque (6) forme un espace filtré au niveau du nez d'un utilisateur, une pluralité de trous de ventilation (9) sont formés dans le corps de masque (6), et des parties de liaison qui relient et fixent le couvercle, le sac filtrant (7) ou le sac filtrant de source d'alimentation (8) sont disposées au niveau de chacun des trous de ventilation (9). Le sac filtrant (7) ou le sac filtrant de source d'alimentation (8) est monté sur la partie de liaison d'au moins un trou de ventilation pour maintenir l'inhalation ou l'expiration du gaz dans l'espace filtré. Le sac filtrant (7) et le sac filtrant de source d'alimentation (8) comprennent chacun un boîtier (10), et deux extrémités de la partie externe de chaque boîtier (10) peuvent être reliées et fixées aux parties de liaison des trous de ventilation (9). La pression à l'intérieur de l'espace filtré ajuste la direction d'entrée et de sortie du gaz au moyen de l'ajustement de la direction de montage du sac filtrant de source d'alimentation (8), et maintient une pression positive ou une pression négative dans l'espace filtré. Le gaz externe est filtré et pénètre dans l'espace filtré, puis est expiré en tant que processus de circulation. Le masque respiratoire peut maintenir une pression équilibrée à l'intérieur du corps de masque, et la respiration avec celui-ci est plus naturelle et lisse.
