摘要： The invention provides a heat-not-burn cigarette product. The heat-not-burn cigarette product of the invention includes a cigarette product and a heater in matched use with the cigarette product. A sucking resistance when the cigarette product and the heater in matched use with the cigarette product are used together is P 1 , and a sucking resistance of the cigarette product is P 2 , wherein a ratio of P 2 /P 1 is greater than or equal to 50%. By controlling a total sucking resistance when the cigarette product and the heater in matched use with the cigarette product are used together, a sucking resistance of each part and a proportional relationship between the sucking resistance of each part and the total sucking resistance, a sucking sense of the heat-not-burn cigarette product according to the invention is greatly improved. The sucking resistance of the cigarette product in the heat-not-burn cigarette product of the invention accounts for more than 50% of the total sucking resistance of the heat-not-burn cigarette product, thus realizing optimized design of an air channel and proper supply of air, realizing balance between the sucking resistance and a smoke amount, and improving a sucking feeling. A sucking resistance of a tobacco section accounts for 40% to 80% of a sucking resistance of a cigarette product section, thus achieving effects of sufficient smoke amount and low interception.
