  • the oil filling hole can also be set at other positions of the sealing member 322, as long as it can be connected with the liquid storage chamber 2020.
  • the top wall of the suction nozzle 321 protrudes and extends the sealing column 3212 in the direction of the sealing member 322, and the sealing column 3212 is sealed and inserted into the oil filling hole.
  • the suction hole 3211 is provided in the sealing column 3212, and the side wall 12 of the sealing column 3212 is provided with an opening connected to the suction hole 3211.
  • the airflow mixed with the aerosol can enter the suction hole 3211 from the opening after passing through the first air hole from the air outlet channel 311, so that the user can inhale. That is, the air suction hole 3211 of the suction nozzle 321 and the air outlet channel 311 form a non-straight air passage, so as to prevent the user from inhaling condensed liquid on the air outlet channel 311 .

Abstract

L'invention concerne un noyau d'atomisation et un atomiseur. L'invention concerne un atomiseur comprenant un noyau d'atomisation. Le noyau d'atomisation comprend un élément de guidage de liquide dur (1) et un élément chauffant (2) ; un côté de l'élément de guidage de liquide dur (1) est en retrait pour former un évidement (10), et la paroi de l'évidement (10) définit une cavité d'atomisation ; l'élément chauffant (2) est placé dans l'évidement (10) et est en liaison de contact avec au moins une partie de la paroi de l'évidement (10). De cette manière, pendant la production et la fabrication du noyau d'atomisation, l'élément chauffant (2) est plus facilement assemblé avec l'élément de guidage de liquide dur (1) dans la direction de l'ouverture de l'évidement (10), et dans le processus de test de noyau d'atomisation, des paramètres associés de l'élément chauffant (2), tels que le diamètre de fil et la distance de fil de l'élément chauffant (2), peuvent être observés ou mesurés à partir de l'ouverture de l'évidement (10), de façon à assurer la fiabilité après que l'élément chauffant (2) est assemblé avec l'élément de guidage de liquide dur (1), ce qui permet d'améliorer les performances de l'atomiseur comprenant le noyau d'atomisation.
