Description

Smoke temperature detection device and detection method for cigarette

Technical Field

With the prevalence of health consumption concepts, a great number of smoking users favor a cigarette which is healthier and does not reduce the smoking taste.

As is well known, there are many kinds of existing cigarettes, such as ordinary cigarettes, cigarettes that do not burn when heated, and the like. In any type of cigarette, when a user smokes, the smoking section on the cigarette needs to be heated to a certain temperature so that the smoking section can generate aerosol (i.e., smoke). And the smoke temperature formed by the cigarettes is over high, and then more toxic and harmful substances such as nicotine and the like are generated. Especially after the cigarette is heated, the user needs to suck the filter rod segment, and if the smoke temperature formed by the cigarette is too high and the smoke temperature is not cooled, the mouth of the user may be scalded.

However, if the heating is too low, the smoking section on the cigarette may not reach the temperature at which it volatilizes to form an aerosol. In the prior art, no special equipment is used for measuring the temperature of smoke formed after the cigarettes are heated, so that a plurality of practically unqualified cigarettes are introduced into the market.

Particularly, after the cooling section is arranged on the cigarette, the cooling effect of the cooling section on the cigarette cannot be accurately measured.
