Abstract

La présente invention concerne un masque de purification d'air comprenant : une partie de corps portée sur et recouvrant le visage de l'utilisateur ; et une partie de purification disposée dans la partie de corps, ayant un canal d'inhalation formé à l'intérieur de celui-ci de façon à guider le trajet d'écoulement d'admission d'air extérieur introduit pendant le processus d'inhalation de l'utilisateur, et ayant un espace de réception d'eau qui est formé sur le canal d'inhalation et dans lequel de l'eau est contenue de façon à permettre à l'air extérieur de passer à travers celle-ci dans le processus de l'écoulement d'admission d'air extérieur, l'air extérieur introduit pendant le processus d'inhalation étant principalement purifié par l'eau contenue dans l'espace de réception d'eau. Par conséquent, le masque de purification d'air peut être utilisé de manière semi-permanente en remplaçant l'eau, et présente ainsi un avantage de réduire le coût de remplacement du filtre.
