As shown in FIG. 1, a disposable consumption includes a housing 6 and a mouth piece 11, a filter 10 is placed inside the mouth piece 11. The housing 6 is in rod shape, front side of the housing 6 is sealed with an aluminum foil 2, thickness of the foil is 0.01 to 0.02 mm. When flame is ignited by premixed butane via a push button, center of the thin aluminum foil 2 is melted letting air flows in. The housing 6 is designed with cooling air hole 1, inhaling cool air to condense steam to generate more vapor. Inside the housing 6, a loose quartz fiber 3 is placed at each end of the housing, thus a chamber for filling tobacco 5 is formed by the two loose quartz fiber 3 and the housing. The chamber is filled with the mixture of secondary heating source 4, tobacco 5 and several soaking plates 7. Between the mouth piece 11 and rear end of the housing 6, there is a macro hole filter 9.

The secondary heating source 4 is made of carbon powder, reduced iron powder and adhesive compacted together, weight ratio of the carbon powder and the reduced iron powder is 1:0.05-1:0.4. The carbon powder has oxidation reaction with the reduced iron powder to consume oxygen. Wherein, the carbon powder consumes oxygen to generate carbon dioxide by micro combustion on the surface of the tobacco, and the reduced iron powder reacts with oxygen and vapor generated by gas burning. The two forms of oxidation reaction simultaneously release heat, to form the secondary heating source of the smoking article. Due to lack of oxygen in the chamber, the tobacco 5 therein does not participate combustion.

Preferably, the tobacco 5 in this embodiment is preprocessed. Making inorganic water solution, including 15% sodium chloride, 8% calcium chloride and 77% water; immersing the tobacco into double amount inorganic salt solution for 2 hours, drying on fluidized bed until water amount is less than 20%; spraying coking agent on tobacco filament or tobacco sheet; continue drying until water amount is less than 10%. Such coking agent is made of 1-7% sucrose, 1-2% dextrin, 1-3% curdlan gum, 0.2-0.8% peanut oil, and rest is water suspension. When the smoking article is smoked, water steam in the chamber meets inorganic salt on the tobacco and they melt together, the micro holes on surface of the tobacco are then sealed, therefore the tobacco will not participate combustion. The coking agent melt with heavy tar with big molecules from tobacco, to form high viscosity material; for the light tar with small molecules from tobacco, the majority of them are vaporized to form smoke.

Such soaking plate 7 is made of metal foil or graphene thermal conductive paper, preferably made of aluminum foil. Its purpose is to balance and distribute heat of the disposable consumption during heating, to prevent partly over heated. Length of the soaking plate 7 is 2-3 mm.
