  • the first support 23 in the aerosol generating device may not be fixedly connected with the second support 121, but fixedly connected with the upper housing 11 (including snap connection, magnetic connection or screw connection, etc.) , for this aerosol generating device, its assembly process is: (1) inject liquid substrate in the liquid storage cavity 111 in the upper housing 11, make the second bracket 121 equipped with the atomization assembly 12 and the upper housing 11
  • the sealing connection is to seal the liquid matrix in the liquid storage chamber 111, and ensure that the liquid matrix can be transferred to the atomization assembly 12 for atomization by the atomization assembly 12, so that the upper housing 11 and the second atomization assembly 12 equipped with
  • the bracket 121 forms a whole, such as a pod; (2) assemble the whole with the first bracket 23 equipped with the power supply assembly 2, thereby forming an aerosol generating device, which can be used when the liquid matrix is exhausted. Reuse by replacing pods.

Abstract

L'invention concerne un appareil de génération d'aérosol comprenant : un boîtier, une cavité de stockage de liquide (111) pour stocker une matrice liquide étant formée à l'intérieur du boîtier ; un premier support (23) ayant un premier espace de maintien ; un ensemble alimentation électrique (2) reçu dans le premier espace de maintien ; un second support (121) disposé dans le boîtier, le second support (121) définissant au moins partiellement la cavité de stockage de liquide (111) et ayant un second espace de maintien (1212) ; un ensemble d'atomisation (12) au moins partiellement reçu dans le second espace de maintien (1212) et utilisé pour atomiser au moins une partie de la matrice liquide provenant de la cavité de stockage de liquide (111) pour générer un aérosol ; un contact électrique (212) relié à demeure au premier support (23), le contact électrique (212) étant électriquement connecté à l'ensemble alimentation électrique (2). Le premier support (23) comprend une extrémité de connexion adjacente au second support (121). Une extrémité d'auto-connexion locale du contact électrique (212) s'étend vers l'extérieur du second support (121) et peut s'étendre dans le second espace de maintien (1212) de façon à venir en butée contre la surface de l'ensemble d'atomisation (12).
