AEROSOL GENERATING APPARATUS

The present invention relates to an aerosol generation device which includes a fixing tube configured for fixing an aerosol-forming substrate, a gas passage tube sleeved around the outer circumference of the fixing tube, and a heating assembly. The fixing tube includes a hollow and two-end-penetrating structure and has two ends that are respectively formed with a first opening and a second opening in communication with the first opening. The gas passage tube has one end provided with a support wall for supporting the aerosol-forming substrate. The support wall is arranged to face the second opening. The aerosol-forming substrate is extendable from the first opening into the fixing tube. The heating assembly is insertable through the support wall to penetrate from the second opening into the aerosol-forming substrate. When the aerosol-forming substrate is withdrawn from the fixing tube toward the first opening, the heating assembly is separated from the aerosol-forming substrate. The aerosol generation device allows efficient and easy withdrawal of the aerosol-forming substrate from the fixing tube without causing damage thereto, possessing an advantage of easy mounting and dismounting.
