Abstract

La présente invention concerne une mèche d'atomiseur à guidage de liquide directionnel multicouche (1) comprenant au moins deux feuilles de base (11) empilées ensemble et des couches diélectriques (12) agencées entre chaque paire de feuilles de base adjacentes (11). La couche diélectrique (12) sépare deux feuilles de base adjacentes (11) et un canal de guidage de liquide (13) est formé entre les deux feuilles de base adjacentes (11) afin de permettre le passage d'un liquide à vapoter. Les couches diélectriques (12) peuvent diviser une mèche d'atomiseur (1) en une structure multicouche. Un canal de guidage de liquide (13) est formé entre deux feuilles de base adjacentes (11) et une position au niveau de laquelle la couche diélectrique (12) est disposée permet au liquide à vapoter de s'écouler dans une direction fixe dans le canal de guidage de liquide (13), ce qui permet de répondre aux exigences d'absorption et d'atomisation de liquide. Les feuilles de base (11) constituent un cadre de la mèche d'atomiseur à guidage de liquide directionnel multicouche (1). Un espace de guidage formé entre les feuilles de base empilées (11) constitue un trajet de transport d'un milieu d'atomisation, tel qu'un liquide à vapoter. Comme l'espace peut stocker une grande quantité d'un milieu d'atomisation, la mèche d'atomiseur (1) présente une structure similaire à une structure poreuse d'une mèche d'atomiseur en céramique.
