  • ⁇ is the surface tension coefficient of the liquid atomization matrix
  • ⁇ is the contact angle
  • R is the radius of the cone.
  • the surface tension coefficient of the liquid atomization matrix is about 0.03 ⁇ 0.045N/m.
  • the liquid atomization matrix and the liquid outlet channel The contact angle of the channel wall of 43 is 30 ⁇ 60°.

Abstract

L'invention concerne un dispositif d'atomisation électronique (1) et un atomiseur (100). L'atomiseur (100) comprend une cavité de stockage de liquide (13), une cavité d'atomisation (421) et un canal de sortie de liquide (43) qui communique avec la cavité d'atomisation (421) et la cavité de stockage de liquide (13), le canal de sortie de liquide (43) ayant une aire de section transversale diminuant progressivement vers la cavité d'atomisation (421) jusqu'à la formation d'une capillarité pour bloquer un milieu d'atomisation liquide. Dans l'atomiseur (100), le canal de sortie de liquide (43) a une aire de section transversale diminuant progressivement vers la cavité d'atomisation (421) jusqu'à la formation d'une capillarité pour bloquer le milieu d'atomisation liquide, ce qui permet d'empêcher le milieu d'atomisation de liquide de refluer et d'empêcher le milieu d'atomisation de liquide de déborder vers la cavité d'atomisation (421), de sorte que le liquide peut être évacué en temps voulu pendant l'atomisation suivante, ce qui permet d'améliorer l'efficacité d'atomisation.
