Description

Cigarette heating device

Technical Field

The invention belongs to the field of electric cigarette heating, and particularly relates to a cigarette heating device.

Background

The existing electric heating non-combustion low-temperature cigarette mainly supplies power to a heating material through a power supply, and generates heat to heat tobacco products, so that tobacco fragrance in the tobacco products distills out and enters into the nose of a human mouth, and the smoking experience same as that of the traditional cigarette is achieved. The heating temperature of the common electric heating cigarette is 180-300 ℃, and the temperature of the common tobacco can not be reached, so that the harmful substances are reduced by at least half, and the harm of the cigarette to human bodies is greatly reduced. Therefore, electrically heated non-combustible cigarettes are increasingly popular with consumers.

The existing electric heating non-burning cigarettes only use a central heating or cup-shaped circumferential heating mode to heat and bake tobacco products, but can not completely release tobacco fragrance in cigarettes, and the heating speed is low, so that the smoking experience of a smoker is seriously affected. Therefore, the heating device capable of fully heating the cigarettes is provided, so that the tobacco flavor is fully enjoyed by people, meanwhile, the insertion and extraction of the cigarettes can be easily realized, and the heating device is convenient to use and is a common expectation of wide smoking lovers.
