Abstract
The invention pertains to the technical field of novel tobacco, and in particular relates to a cigarette structure for heat-not-burn cigarettes. A heat-not-burn cigarette comprising: an envelope that is cylindrical and hollow, a cleaning isolation sleeve disposed at a front end of the envelope, and a smoking article zone and a cooling and filtration zone sequentially disposed in the envelope. With the cleaning isolation sleeve, the invention prevents the tobacco shreds from dropping out when a user inserts the heating body into the cigarette, and prevents fine part in the smoking article from falling into the heater during heating, thereby ensuring cleanness of the heater.
