Document Type and Number:
WIPO Patent Application WO/2022/116559
Kind Code:
A1
Abstract:
A heat insulation structure and an aerosol generation device. The heat insulation structure is used inside a housing (200) of the aerosol generation device and comprises an inner support (10), an airflow separator (20) and a heat insulation base (30), wherein an opening (11) in the upper end of the inner support (10) forms a containing cavity used for containing an aerosol forming substrate (100), a through hole (12) in communication with the containing cavity is provided in the middle of the bottom end of the inner support (10), and an annular airflow cavity (70) is formed between an outer wall of the inner support (10) and an inner wall of the housing (200); the airflow separator (20) is sleeved on the inner support (10) and divides the airflow cavity (70) into a first annular airflow channel (71) and a second annular airflow channel (72) from outside to inside, the upper ends of the first airflow channel and the second airflow channel are in communication with each other, the lower end of the second airflow channel (72) is in communication with the through hole (12), and the first airflow channel (71) is in communication with an air inlet (203) provided in the housing (200); and the heat insulation base (30) is arranged at the lower end of the interior of the airflow separator (20) and used for fixing a heating body (300), and at least part of the heating body (300) extends into the containing cavity via the through hole (12) and is used for heating the aerosol forming substrate (100) contained in the containing cavity so as to generate aerosol.
