In this application, it should be understood that terms such as "comprising" or "having" are intended to indicate the presence of features, numbers, steps, acts, components, parts or combinations thereof disclosed in this specification and are not intended to exclude a or multiple other features, numbers, steps, acts, components, parts, or combinations thereof may exist.

In addition, it should be noted that the embodiments of the present application and the features of the embodiments may be combined with each other if there is no conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Referring to FIG. 1 , an embodiment of the present application provides a heat-not-burn tobacco appliance, comprising a tobacco material containing chamber 1, a heating element 2, a temperature sensor 3, a temperature controller 4 and a power supply module 5, and the heating element 2 is used for heating the tobacco material The tobacco in the accommodating cavity 1 is heated, the temperature sensor 3 is used to detect the temperature of the tobacco in the tobacco material accommodating cavity 1, the power supply module 5 is used to provide driving power for the heating element 2, and the controller is used to set the power supply module 5 to provide the heating element 2 with a driving power. output power. In some specific structures, controlling the output voltage provided by the power supply module 5 to the heating element 2 is equivalent to controlling the output power provided by the power supply module 5 to the heating element 2 .

For the temperature control method for a heat-not-burn tobacco appliance provided by the embodiments of the present application, from an equipment perspective, the execution body may be the temperature controller 4 in the heat-not-burn tobacco appliance; from a program perspective, the execution body is correspondingly It may be a program mounted on these heat-not-burn tobacco appliances.

2 and 3, in conjunction with FIG. 1, the temperature control method includes the following steps.

Step S1, after starting to heat the tobacco, after the tobacco is heated up to a third temperature threshold, control the temperature of the tobacco to maintain a first time length within the range from the third temperature threshold to the fourth temperature threshold, and the third temperature threshold is controlled. The third temperature threshold is denoted as T3, and the fourth temperature threshold is denoted as T4.

Step S2, controlling the temperature of the tobacco, and maintaining the temperature of the tobacco within a range from a first temperature threshold to a second temperature threshold, the first temperature threshold is denoted as T1, and the second temperature threshold is denoted as T2; Wherein, it satisfies: T4>T3>T2>T1>0°C.

In the initial stage, the temperature of the tobacco is maintained within the higher temperature range of the third temperature threshold and the fourth temperature threshold. Because the temperature is high enough, enough heat is generated that the tobacco absorbs more heat in a short time, which in turn produces enough smoke. The temperature interval formed by the first temperature threshold and the second temperature threshold is appropriately lower than the temperature interval formed by the third temperature threshold and the fourth temperature threshold, which can improve the taste, and the amount of smoke generated is more suitable for users to smoke. In this way, the user experience can be better improved.

Referring to FIG. 4 , and in conjunction with FIG. 1 and FIG. 3 , the implementation details of the temperature control method are described below.

When a signal to start heating the tobacco is received, the first process is entered, wherein the output power provided to the heating element 2 is set as the first power, and the first power is denoted as P1.

The first power should be large enough to shorten the temperature rise time as much as possible, so as to make the tobacco smoke more quickly. Referring to FIG. 4, after the heating of the tobacco is started, the temperature of the tobacco rises rapidly. However, it is not suitable for users to smoke at this time, because the tobacco does not absorb enough heat.

When the temperature of the tobacco reaches the third temperature threshold, the second process is entered, wherein the output power provided to the heating element 2 is set as the second power, so that the tobacco is heated up, and the heating speed is lower than that in the first process. The heating rate, the second power is recorded as P2.

When the temperature of the tobacco reaches the fourth temperature threshold, the third process is entered, wherein the output power provided to the heating element 2 is set as the third power to cool the tobacco, and the third power is denoted as P3.

Enter the second process and the third process alternately, and stop when the total duration of the second process and the third process reaches the first time duration.

The second process and the third process are performed alternately in order to maintain the temperature of the tobacco within the temperature range of the higher third temperature threshold and the fourth temperature threshold. Because the temperature is high enough, enough heat is generated that the tobacco absorbs more heat in a short period of time. The phase in which the second process and the third process alternate is a "preheating phase".

Enter the fourth process, wherein the output power provided to the heating element 2 is set as the fourth power to cool the tobacco. If the temperature of the tobacco is always high, too much smoke is generated, and the smoke temperature is too high, and the user experience is not good. The purpose of the fourth process is to appropriately lower the temperature of the tobacco. In order to shorten the time of this process, the fourth power can be set as P4=0W. That is, the heating of the tobacco is completely stopped.

When the tobacco is cooled to the first temperature threshold, the fifth process is entered, wherein the output power provided to the heating element 2 is set as the fifth power to heat the tobacco, and the fifth power is recorded as P5.

When the temperature of the tobacco reaches the second temperature threshold, the sixth process is entered, wherein the output power provided to the heating element 2 is set as the sixth power to cool the tobacco, and the sixth power is denoted as P6.

Alternately enter the fifth process and the sixth process.

The temperature interval formed by the first temperature threshold and the second temperature threshold is appropriately lower than the temperature interval formed by the third temperature threshold and the fourth temperature threshold, which can improve the taste, and the amount of smoke generated is more suitable for users to smoke.

Of course, the fourth power may also be smaller than the sixth power but not 0W.

The duration of the alternation of the fifth process and the sixth process is recorded as TIME2, which is usually a program setting value. The purpose is to stop heating after the tobacco is consumed. Heating was then stopped and the tobacco cooled. The duration of the alternation of the fifth process and the sixth process is usually 3min-4min.

In the above embodiment, it satisfies: T4>T3>T2>T1>0, P1>P2>P3≥0, and P1>P5>P6≥0.

Of course, in order to simplify the temperature control method, P1=P2, or P1=P5 can also be set.

For different types of tobacco and different types of heat-not-burn tobacco appliances, the values of the above parameters can be adjusted appropriately.

Optionally, T1≥260°C. This is to keep tobacco producing smoke all the time.

Optionally, the first duration is recorded as TIME1, which satisfies: 12s≤TIME1≤60s.

In a specific experimental example, TIME1=15s.

Optionally, 310°C≤T1<T2≤350°C. For most tobaccos, a moderate amount of smoke at the right temperature can be produced within this temperature range.

Optionally, 350°C≤T3<T4≤390. For most tobaccos, a large amount of smoke can be produced rapidly in this temperature range without compromising the quality of the tobacco.
