Abstract

L'invention concerne une cartouche de cigarette électronique dotée d'une structure de valve de fluide unidirectionnelle, et l'application de la cartouche de cigarette électronique. La cartouche de cigarette électronique comprend un boîtier de cartouche (100) ; un corps de structure de valve unidirectionnelle (300) relié au boîtier de cartouche (100) ; un élément d'atomisation métallique poreux (400) relié au corps de structure de valve unidirectionnelle (300) ; et une base (500) reliée à l'élément d'atomisation métallique poreux (400). Le corps de structure de valve unidirectionnelle (300) a une structure de valve de Tesla (301). Dans la valve de Tesla (301), un fluide, lorsqu'il s'écoule dans des directions avant et arrière, est soumis à différentes résistances. Par conséquent, en concevant de manière rationnelle la taille d'un corps de tube de valve de Tesla (301), la valve de Tesla peut guider de l'air au lieu d'un liquide, autrement dit, celle-ci est reliée vers l'avant avec le vapotage, de manière à réguler la pression d'air d'une chambre de liquide et assurer une alimentation en liquide régulière ; et une différence de pression peut également être consommée au moyen d'une résistance vers l'arrière, ce qui permet de résoudre et de réduire le problème d'un liquide qui fuit d'une cartouche de cigarette électronique sous une pression négative de haute altitude.
