Abstract

La présente invention concerne un dispositif de protection respiratoire électrique en interfonctionnement avec la respiration, et plus particulièrement un dispositif de protection respiratoire électrique en interfonctionnement avec la respiration, qui comprend : une partie de masque portée sur une zone faciale de façon à entourer la bouche ou les narines d'un utilisateur; une partie de générateur qui introduit de l'air externe, filtre l'air introduit, et distribue l'air filtré vers la partie de masque; une partie de raccordement formée pour permettre le passage de l'air filtré par raccordement de la partie de masque et la partie de générateur sur les deux côtés de ceux-ci; et une partie de support de cou fixée aux deux côtés de la partie de raccordement et formée pour soutenir l'arrière du cou de l'utilisateur tout en entourant l'arrière du cou, la partie de générateur fonctionnant en interfonctionnement avec la respiration de l'utilisateur de telle manière que l'air externe soit fraîchement introduit par l'intermédiaire d'un ventilateur lorsque l'inspiration de l'utilisateur est détectée. Selon la présente invention, étant donné que le dispositif de protection respiratoire électrique doit simplement être couplé à une visière de soudage anti-éblouissante automatique de types de casques ou de lunettes de sécurité existants, le dispositif de protection respiratoire électrique a un effet économique en ce que le dispositif de protection respiratoire électrique est aisément miniaturisé et mis en pratique, et des coûts de distribution relativement faibles sont obtenus, de façon à améliorer la compétitivité des prix, par rapport à un dispositif de protection respiratoire électrique selon l'art connexe. En outre, le dispositif de protection respiratoire électrique présente un effet d'entraînement significatif dans différents domaines industriels, étant donné que le dispositif de protection respiratoire électrique peut être utilisé indépendamment dans des ateliers dans lesquels des substances nocives peuvent être inhalées, tels qu'un atelier de polissage de métaux, un atelier d'élimination d'amiante, un chantier de construction, un atelier de manipulation de substances dangereuses, et un chantier de construction de tunnel, en plus d'un atelier de soudage.
