Abstract

La présente invention concerne une unité de vaporisation d'un dispositif de génération de microparticules. Plus spécifiquement, la présente invention concerne un élément chauffant en céramique d'un dispositif de génération de microparticules dans lequel un matériau ayant une faible différence de taux de transfert de chaleur par rapport à une bobine de chauffage contient un liquide et peut ainsi empêcher la carbonisation. La présente invention concerne un élément chauffant en céramique d'un dispositif de génération de microparticules comprenant : une céramique poreuse qui absorbe et stocke un liquide ; et un élément chauffant qui est relié à la céramique poreuse et qui génère de la chaleur lorsqu'un courant est appliqué à celui-ci, le liquide supporté par la céramique poreuse étant vaporisé par la chaleur générée par l'élément chauffant. De plus, la présente invention concerne une structure d'installation d'élément chauffant en céramique pour un dispositif de génération de microparticules comprenant : une unité de stockage de liquide dans laquelle un liquide est stocké ; un espace de vaporisation qui est disposé à l'intérieur de l'unité de stockage de liquide et dans lequel un liquide est chauffé et vaporisé ; un canal d'introduction à travers lequel de l'air est introduit dans l'espace de vaporisation ; un canal d'évacuation à travers lequel de l'air est évacué de l'espace de vaporisation ; et un élément chauffant en céramique qui comprend un corps en céramique disposé sur la surface inférieure de l'espace de vaporisation, et une bobine de chauffage installée sur le corps en céramique.
