Abstract (en)
[origin: EP3804542A1] A heat-not-burn tobacco stick consists of a hollow cylinder (5), a cleanness and isolation sleeve (1) provided at a front end of the cylinder (5), and a smoke generation article section (3) and a cooling and filtering section (7) sequentially provided inside the cylinder (5). Provision of the cleanness and isolation sleeve (1) prevents tobacco shreds from falling out when a user inserts a heating member into a tobacco stick, and prevents fine particles in a smoke generation article from entering a heater in a heating process, thereby ensuring cleanness of the heater.
