In the utility model, the stage of preheating the tobacco part 401 is enveloping heating, this stage will not make the cigarette 4 generate smoke, the air heating stage instantly heats the air around the air heating unit 3, and passes through the air distribution seat 6 (hot air distribution stage) ), the hot air enters the cigarette 4 to bake the cigarette 4 to make it produce smoke. The whole working process is divided into the following three stages:

The first heating (preheating the tobacco part 401) stage: the preheating unit 5 (heating tube) preheats the tobacco part 401 of the cigarette 4 to a set temperature of 140°~190° (preferably 150°~180°) and then keeps it warm.

The second heating (heating air) stage: the air heating unit 3 rapidly heats the air (the temperature of the air entering the cigarette 4 is set at 150°~230°, preferably 180°~220°).

The third stage: after the hot air enters the distribution seat 6, it is dispersed from the multiple first air holes 6011 provided on the distribution seat 6 to the surroundings, and finally the hot air is divided into multiple hot air and enters the cigarette branch 4 to dry the cigarette branch 4 Smoke out.

The working process of the present utility model is as follows:

The cigarette 4 is inserted into the accommodating chamber 501, the control switch 15 is activated, the preheating unit 5 works, and the heating tube starts to preheat the tobacco part 401 of the cigarette 4, and the preset temperature is 150°~180°. After the preheating unit 5 reaches the set temperature, continue to preheat the temperature and keep the temperature of the preheating unit 5 at a constant temperature. The air temperature reaches 180°~220°. After the hot air reaches the preset value, the user is notified by the indicator light that the suction can be started. At this time, the hot air enters the cigarette holder 4 through the distribution seat 6, and the cold air outside enters the inside of the product from the air inlet 8 at the same time. Through the second heating stage, the air is rapidly heated, and then the hot air flow is dispersed into multiple strands of hot air through the diverter seat 6 to heat the cigarette 4 . Since the preheated hot air enters the cigarette 4 at the first time, the user will not feel the delay of the smoke when using it.

Since the preheating temperature of the cigarette 4 in the first stage is not enough to let the cigarette 4 emit smoke, the hot air preheated in the second stage enters the cigarette 4 to further heat the cigarette 4, so that the temperature of the cigarette 4 reaches the atomization level The baking temperature is higher, so that smoke is generated, the temperature required for atomization is lower, and the harmful gas substances produced will be greatly reduced.
