When the aerosol generating product 40 is placed in the receiving portion 31, the probe 221 can extend into the aerosol producing product located in the receiving portion 31 through the through hole 3111 to heat the aerosol producing product.
  • the receiving seat 3 also includes a convex portion 34, which is provided on the bottom wall 311 of the receiving portion 31 and extends upward toward the opening end 102 along the periphery of the through hole 3111, so as to facilitate the probe 221 to pass through the through hole 3111 and prevent the residual liquid at the bottom of the receiving portion 31 from flowing out of the through hole 3111.
  • the aerosol generating device 100 of the present invention cooperates with the airway structure 5 through the heat dissipation portion 63 of the heat dissipation device 6, and dissipates the heat generated by the microwave generating device 20 through the airflow of the airway structure 5, thereby improving the heat dissipation efficiency of the solid microwave source.
  • the heat dissipation portion 63 can be in contact with the microwave heating component 10, and the cavity 103 is used to increase the heat dissipation area, and the cavity 103 is kept warm, which can reduce the heat radiation or heat conduction from the aerosol generating product 40 to the outside, improve the energy utilization rate, and greatly reduce the time for the atomized medium to be heated to the controlled temperature (reduce the heating time duty cycle), thereby improving energy efficiency.

Abstract

L'invention concerne un dispositif de production d'aérosol, comprenant un ensemble de chauffage par micro-ondes (10) pour chauffer un article de production d'aérosol (40) ; une structure de canal d'air (5) qui correspond à l'ensemble de chauffage par micro-ondes (10) et est utilisée pour guider un gaz externe dans l'ensemble de chauffage par micro-ondes (10) ; un dispositif de production de micro-ondes (20), comprenant une source de micro-ondes à l'état solide ; et un dispositif de dissipation de chaleur (6), comprenant une partie d'absorption de chaleur (61), une partie de conduction de chaleur (62) ayant une extrémité reliée avec thermoconduction à la partie d'absorption de chaleur (61), et une partie de dissipation de chaleur (63) reliée avec thermoconduction à l'autre extrémité de la partie de conduction de chaleur (62), la partie d'absorption de chaleur (61) étant reliée avec thermoconduction à la source de micro-ondes solide, et la partie de dissipation de chaleur (63) correspondant à la structure de canal d'air (5). Selon le dispositif de génération d'aérosol, en faisant correspondre la partie de dissipation de chaleur (63) du dispositif de dissipation de chaleur (6) et la structure de canal d'air (5), la chaleur produite par le dispositif de production de micro-ondes (20) est dissipée au moyen de flux d'air de la structure de canal d'air (5), ce qui permet d'améliorer l'efficacité de dissipation de chaleur pour la source de micro-ondes à l'état solide.
