Title
(EN) ATOMIZATION UNIT
(FR) UNITÉ D'ATOMISATION
(JA) 霧化ユニット
Abstract
(EN)
An atomization unit comprises a piezoelectric element substrate that has comb-shaped electrode pairs, and a liquid supply unit that is configured so as to supply a liquid to be atomized to the piezoelectric element substrate. The piezoelectric element substrate is configured so that the liquid is atomized by surface elastic waves generated by applying a voltage at a high frequency to the comb-shaped electrode pairs. The number of comb-shaped electrode pairs in the piezoelectric element substrate is determined on the basis of a desired aerosol to be atomized by surface elastic waves.

L'invention concerne une unité d'atomisation, comprenant un substrat d'élément piézoélectrique qui porte des paires d'électrodes en forme de peigne et une unité d'apport de liquide qui est conçue de manière à apporter un liquide à atomiser au substrat d'élément piézoélectrique. Le substrat d'élément piézoélectrique est conçu de telle sorte que le liquide est atomisé par des ondes élastiques de surface produites par application d'une tension à une fréquence élevée aux paires d'électrodes en forme de peigne. Le nombre de paires d'électrodes en forme de peigne dans le substrat d'élément piézoélectrique est déterminé sur la base d'un aérosol souhaité à atomiser par des ondes élastiques de surface.
