Electronic cigarette example

As shown in FIG. 4 , the electronic cigarette includes a power source 11, a cigarette 12, a casing 13, and a button 14 on one side of the casing 13. The cigarette 12 includes a connected tobacco part 1201 and a mouthpiece 1202, and the casing 13 is provided with the first embodiment. The atomizing core 15 , the first heating unit 2 and the second heating unit 3 are all connected to the main board 16 and are electrically connected to the power supply 11 through the button 14 . The direction indicated by the arrow in FIG. 4 is the direction of the airflow.

The electronic vaping method of the present invention comprises the following steps:

Step A1. Preheating the tobacco part 1201 of the cigarette 12 to the critical temperature of atomization; the critical temperature of atomization is 130°C to 160°C, preferably 140°C to 150°C.

Step A. Outside air enters the intake passage 1 .

Step B. Heating the air in the air inlet channel 1 to the atomization temperature; the atomization temperature is 230°C to 280°C, preferably 240°C to 250°C.

Step C. The air heated to the atomization temperature flows through the tobacco part 1201 that has been preheated to the atomization critical temperature, and the tobacco part 1201 is endothermic and atomized to generate smoke for the user to smoke.

As shown in FIG. 5 , curve ① represents the relationship between the temperature and time of the first heating unit 2 when the button 14 is pressed. When the button 14 is pressed, the first heating unit 2 preheats the tobacco part 1201 to the atomization critical temperature of 150°C within 10s to 30s, that is to say, the heating temperature of the first heating unit 2 is only for the tobacco part 1201 is heated and kept warm, and does not cause the tobacco part 1201 to produce smoke. When the temperature of the first heating unit 2 reaches the preset critical temperature for atomization, the controller controls the constant power of the first heating unit 2 to work so that the tobacco part 1201 is kept constant within the critical temperature range of atomization, so that the smoke can be quickly released during smoking for users to consume.

As shown in FIG. 5 , the curve ② represents the relationship between the temperature of the second heating unit 3 and the time during smoking after pressing the button 14 . When smoking, the airflow sensing switch 5 detects that air enters the intake passage 1, and the second heating unit 3 is connected to the power supply 11 through the airflow sensing switch 5, and the second heating unit 3 rapidly heats the air entering the intake passage 1 , so that the temperature of the air there quickly rises to the atomization temperature. Then the hot air rising to the atomization temperature passes through the tobacco part 1201 of the cigarette 12 in the form of airflow, the tobacco part 1201 absorbs the heat of the hot air, so that the temperature of the tobacco part 1201 is higher than the atomization critical temperature and atomized to generate smoke for the user Suck.

Since the tobacco part 1201 has been preheated by the first heating unit 2 to the critical temperature for atomization, when the hot air heated by the second heating unit 3 passes through the tobacco part 1201 in the form of airflow, the tobacco part 1201 absorbs a small amount of heat and can be atomized chemical production of smog. At the same time, since the hot air fills each tobacco unit of the tobacco part 1201 during smoking, and each tobacco unit of the tobacco part 1201 has been preheated to the atomization critical temperature by the first heating unit 2, each tobacco unit of the tobacco part 1201 The unit is heated evenly and the temperature of each smoke produced is constant, and the smoke tastes better. In addition, due to the pre-heating of the first heating unit 2, the hot air temperature of the second heating unit 3 does not need to be too high to atomize the tobacco part 1201, so the electronic cigarette does not need too much heat insulation structure to achieve good performance The thermal insulation effect is simple, so the structure is simple and the production cost is reduced.

As can be seen from the curve ③ in FIG. 6 , since the first heating unit 2 is mainly used for preheating the tobacco part 1201, and the temperature of the hot air flowing through the tobacco part 1201 is higher than the preheating temperature of the tobacco part 1201, during the smoking process, the hot air is heated. The airflow will not absorb the heat of the first heating unit 2, so the temperature of the first heating unit 2 will not change too much, so the smoke output speed of the tobacco part 1201 can be better ensured. Therefore, the heating power required by the first heating unit 2 in the later stage is constant, so the battery life is longer.

It can be seen from the curve ④ in FIG. 6 that during the smoking process, when the hot air of the second heating unit 3 passes through the tobacco portion 1201, since the heat in the hot air is continuously absorbed by the tobacco portion 1201, the temperature of the hot air varies with the heat. The air flow enters the length of the tobacco part 1201 and gradually decreases, and the temperature of the drop is about 20 ° C ~ 50 ° C, but at the smoke outlet end of the tobacco part 1201, the temperature of the hot air flow can at least atomize the tobacco product section through which the hot air passes. Produce smoke to meet users' needs for smoke.
