Different from the traditional combustion type cigarette, the heating non-combustion (HNB) smoking set releases nicotine and smoke in tobacco by heating the tobacco at low temperature. The low-temperature heating temperature is generally about 300 ℃ and is far lower than the combustion temperature of the combustion type cigarette above 800 ℃. Under the condition of low-temperature heating, the content of harmful substances in smoke released by tobacco is far lower than that of combustion type cigarettes, so that the harm of tobacco products to human bodies is greatly reduced.
The existing heating modes of heating the non-combustion smoking set mainly comprise peripheral heating, central heating and air heating. In the peripheral heating method, a heating body is provided on a cup for holding cigarettes so as to heat the cigarettes in the cup at a low temperature from the periphery. In the center heating method, a sheet-like or needle-like heating element is inserted into a cigarette and low-temperature heating is performed from the center of the cigarette. In the air heating mode, the heating element heats air flowing through the heating element, and the heated hot air further heats cigarettes.

The description of the exemplary embodiments is merely illustrative and is not intended to limit the invention, its application, or uses. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It should be noted that: the relative arrangement of parts and steps, numerical expressions and numerical values set forth in these embodiments should be construed as merely exemplary, and not limiting, unless otherwise specifically stated.
Fig. 1 shows a flowchart of a control method of an electric smoking set heat-generating body according to an embodiment of the present invention. The method of the present embodiment may be used to control the temperature of a heat-generating body that heats a non-burning electronic smoking article. The heating element may be a heating element of a peripheral heating, center heating or air heating type electronic smoking set, which is not limited in this embodiment. As shown in fig. 1, the method for controlling the temperature of the heating element of the electronic smoking set of the present embodiment includes:
firstly, executing a preheating program 10 to increase the temperature of the heating element to a preheating temperature T1;
then, the keeping warm program 11 is executed, the heating element temperature is kept at the temperature before the keeping warm program 11 is started for the keeping warm period t1,
if a pumping action is detected within the warm-up period t1, the warm-up routine 12 is executed,
if no pumping action is detected within the warm-up period t1, the cool-down procedure 13 is executed,
wherein the temperature raising program 12 raises the heating element to a temperature T2, and then the temperature keeping program 11 is executed;
wherein the temperature lowering program 13 lowers the temperature of the heating element to a temperature T3,
if a pumping action is detected during the execution of the cooling program 13, the heating program 12 is executed,
if the pumping action is not detected during the execution of the cool-down program 13, the temperature control method is ended.
Fig. 2 to 5 are temperature graphs of a heat-generating body with time when the temperature control method of the present embodiment is performed. The temperature control method of the present embodiment will be described in detail below with reference to fig. 2 to 4.
After a user inserts a cigarette into the cup and starts the electronic smoking set, the electronic smoking set first performs a preheating procedure 10. In the preheating routine 10, the heating element temperature reaches a preheating temperature T1 at which the cigarettes can be heated for smoking by the user from room temperature. In the heat-generating body temperature charts shown in FIGS. 2 to 5, the heat-generating body reached the preheating temperature T1 at time ta. When it is detected that the temperature of the heating element has reached the preheating temperature T1, the electronic smoking set may prompt the user with a sound and/or light to make the user aware that the electronic smoking set has been preheated and may begin smoking. According to a preferred embodiment of the present invention, the preheating temperature T1 may be set in a range between 150 degrees and 400 degrees. For example, the preheating temperature T1 of the heating element of the peripheral heating type electronic smoking set is generally between 200 degrees and 300 degrees, and the preheating temperature T1 of the heating element of the central heating type electronic smoking set is generally between 300 degrees and 400 degrees. In the present embodiment, the temperature of the heat generating body may be directly or indirectly derived by a temperature sensor or by a change in, for example, the resistance value of the heat generating body. In other embodiments, the temperature of the heating element may be measured by any temperature measuring method known in the art, and the present invention is not limited thereto.
After the execution of the preheating program 10 is completed, the electronic smoking article executes the keeping warm program 11 to keep the temperature of the heating body. In the message program 10 executed for the first time after the warm-up period, the temperature of the heat generating body is maintained at the warm-up temperature T1. The keeping warm routine 11 keeps the heating element temperature at the temperature before the start of the keeping warm routine 11 for the keeping warm period t 1. When the suction operation is detected in the temperature keeping period t1 and the temperature of the heating element is lowered by the suction operation, the temperature raising program 12 is started to raise the temperature of the heating element; if no pumping action is detected within the temperature keeping period t1, the temperature lowering process 13 is started. The keeping warm period t1 is the preset longest length of time that the keeping warm program 11 is executed. In the heat-generating body temperature charts shown in FIGS. 2 to 5, the period from time ta to time tb is the heat-keeping period t 1.
The length of time that the incubation program 11 is actually executed depends on whether the e-smoking article has detected a smoking action by the user during the incubation period t 1. The value of the keeping warm period t1 may be set, for example, between 0.5 second and 20 seconds. If a user's pumping action is detected within the warm-up period t1, the warm-up routine 12 is executed without continuing the warm-up routine 11. As shown in fig. 2 and 3, in the temperature keeping period t1 (i.e., from time ta to time tb), since the suction action by the user is detected, the temperature increasing program 12 is executed to increase the heat generating body temperature. In fact, when a user sucks a cigarette, the temperature of the heating body can be suddenly reduced, so that the cigarette is insufficiently heated in the subsequent use process, and the smoking taste of the user is further influenced. In this embodiment, after the suction action of the user is detected, the temperature raising program 12 is executed immediately, so as to offset the heat loss of the heating element caused by the suction of the user, and to rapidly raise the temperature of the heating element, so as to improve the consistency of the smoking status of the cigarettes, and further improve the smoking taste of the user.
If no pumping action is detected within the temperature keeping period t1, i.e. no pumping action of the user is detected during the execution of the temperature keeping program 11, the temperature lowering program 13 is executed. As shown in fig. 4 and 5, the suction action of the user is not detected during the keeping warm period T1 (i.e., from time ta to time tb), and the temperature of the heat-generating body is maintained at the temperature before the execution of the keeping warm program 11 is started (i.e., the temperature T1). After the execution of the heat keeping program 11 is completed (i.e., after time tb), the temperature lowering program 13 is executed to lower the temperature of the heating element. In fact, when the smoking action of the user is not detected within the heat preservation time period t1, the temperature of the heating element is continuously kept, on one hand, the energy of the battery of the electronic smoking set is wasted, the endurance time of the electronic smoking set is reduced, on the other hand, the cigarette is overheated, and the subsequent smoking taste of the user is affected. Therefore, the temperature reduction program 13 is executed immediately after the execution of the temperature keeping program 11 is finished, so that on one hand, the battery energy of the electronic smoking set can be saved, the endurance time of the electronic smoking set can be prolonged, and on the other hand, the taste of smoking cigarettes by subsequent users can also be improved.
In the present embodiment, the temperature increasing routine 12 increases the heating element to the temperature T2, and then the temperature keeping routine 11 is executed.
The temperature T2 may be dynamically set based on the user's pumping action. Specifically, T2 may depend on the total number of puffs after the warm-up procedure 10, the magnitude of the suction force of the current puff, and the duration of the current puff. In addition, the temperature T2 may further depend on the number of consecutive puffs. By dynamically setting the raised temperature T2 according to the suction action of the user, the consistency of the smoking status of the cigarettes can be improved, and the smoking taste of the user is improved. Specifically, the temperature T2 may be calculated by the following formula:
t2 ═ f (P, c, T, a) ═ T1+ K1 × P + K2 × c + h (a, T) formula 1
Wherein T1 is the preset preheating temperature, P is the total times of suction after the preheating program 10, c is the current continuous times of suction, A is the suction amplitude (in ml/s) of the current suction action, T is the duration of the current suction action, h is a function of A and T, and K1 and K2 are preset fixed parameters. The values of K1 and K2 range from 0.1 to 5. A specific expression for h (a, t) may be, for example:
wherein ka, kt and kd are all preset fixed parameters, and the value range of ka, kt and kd is between 0.1 and 5.
The electronic smoking article may count the total number of user puffs after the pre-heating program 10 to obtain a value for the variable P. The suction amplitude a and the duration t of the suction action may be directly obtained by an airflow sensor disposed in an airflow channel of the electronic smoking set, or may be indirectly obtained by a temperature change of the heating element, which is not limited in the present invention.
The number of continuous suctioning times c can be obtained by determining the relationship between the time interval between the current suctioning operation and the previous suctioning operation and the preset interval threshold t 2. Specifically, the warming program 12 may include: whether the current suction operation is continuous suction is determined based on the relationship between the time interval between the start time of the current suction operation and the end time of the previous suction operation and the suction interval threshold t 2. The suction interval threshold t2 may be, for example, in the range of 0.5 seconds to 15 seconds.
If the time interval between the current suction action starting time and the last suction action ending time is larger than the suction interval threshold value t2, namely the time interval between two suction actions is too long, the current suction action is judged as discontinuous suction. In the case of discontinuous suction, c is 0. As shown in fig. 2, the suction operation of the user is detected between time ta and time tb, and the number of consecutive suctions c is 0 because the suction operation does not occur before the suction operation. In the temperature raising program 12 triggered by the pumping action, c is substituted into 0 in formula 1 to calculate the temperature to which the heating element is raised. After the execution of the temperature increasing program 12 is completed, the temperature keeping program 11 is executed (time tb to time tc).
If the time interval between the current suction action starting time and the last suction action ending time is less than or equal to the suction interval threshold t2, that is, the time interval between two suction actions is short, the current suction action is determined as continuous suction. At this time, the calculation formula of the number of continuous puffs is c ═ cp +1, where cp is the number of continuous puffs at the time of the last puff. For example, after the warm-up program 10, if it is detected that the user has performed three suction operations in sequence, and the time interval between the second suction operation and the first suction operation is smaller than t2, the number of continuous suction operations in the second suction operation is 1, that is, one continuous suction operation is performed. If the time interval between the third suction operation and the second suction operation is also less than t2, the number of continuous suctions in the third suction operation is equal to the number of continuous suctions in the second suction operation plus 1, i.e., equal to 2. If the number of continuous aspirations at the time of the second aspiration is 0 and the number of continuous aspirations at the time of the third aspiration is determined to be 1. As shown in fig. 3, the first pumping action is detected between time ta and time tb, and therefore the temperature increasing routine 12 is executed. After the execution of the temperature increasing program 12 is completed, the temperature keeping program is executed from time tb. The second pumping action is detected between times tb and td, and therefore the temperature increasing routine 12 is executed again. Since the time interval between the start timing of the second suction operation and the end timing of the first suction operation is smaller than the suction interval threshold t2, and the first suction-time continuous suction frequency cp is 0, the second suction-time continuous suction frequency c is 1. In the temperature raising program 12 triggered by the second pumping action, c ═ 1 is substituted into equation 1 to calculate the temperature to which the heating element is raised. After the execution of the temperature increasing program 12 is completed, the execution of the temperature keeping program 11 is started.
In fig. 2 to 5, the temperature change curve of the heat generating element is drawn as a dotted straight line when the temperature increasing program is executed. It is noted that the dashed straight lines depicted in fig. 2 to 5 only schematically represent the warming trend. In practice, the form of the temperature change curve of the heat generating body during the execution of the temperature increasing program 12 is changed under the influence of the smoking action of the user (e.g., the amount of suction force of the user, the pumping time period, etc.), and the form of the temperature change curve of the heat generating body includes, but is not limited to, the forms of the curves shown in fig. 6A to 6C.
In the present embodiment, the temperature lowering program 13 lowers the heating element temperature to the temperature T3. If a pumping action is detected during the execution of the temperature lowering routine 13, the temperature raising routine 12 is executed. If the pumping action is not detected during the execution of the cool-down program 13, the temperature control method is ended.
The temperature T3 to which the heat generating body is lowered depends on the length of time the temperature lowering routine 13 is executed. The length of time that the cooling program 13 is executed may be a predetermined fixed value, and may range from 4 seconds to 90 seconds, for example. The longer the cooling program 13 is executed, the lower the heating element temperature is decreased. Specifically, the temperature T3 to which the heat generating body falls can be determined by the following formula:
T3＝f(d)＝T p -K3 × d formula 3
Wherein, T p The temperature of the heating element before the cooling procedure 13 is executed, d is the time duration of the cooling procedure 13, and K3 is a predetermined fixed parameter. K3 can have a value in the range of 0.1 to 5, for example.
During the execution of the temperature lowering program 13, if a pumping action of the user is detected, the temperature raising program 12 is executed to raise the temperature of the heating element to improve the taste of the user. As shown in fig. 4 and 5, during execution of the temperature lowering program 13, the suction action of the user is detected, and therefore the temperature raising program 12 is executed instead to raise the temperature of the heat generating body. In fig. 4, the user has performed only one puff, whereas in fig. 5, the user has performed two puffs with a time interval of less than t2 (i.e., continuous puffs), and thus only one temperature increasing program 12 is performed in fig. 4, whereas two temperature increasing programs 12 are performed in fig. 5.
If the pumping operation of the user is not detected during the execution of the cooling program 13, the temperature control method of the present embodiment is ended after the execution of the cooling program 13 is completed, and power is not supplied to the heating element. The temperature of the heat generating body is thus gradually lowered to the ambient temperature. In a preferred embodiment, a prompt signal (e.g., a sound signal or a vibration signal) may be issued to the user before the cooling program 13 ends in order to prompt the user. After the temperature control method of the present embodiment is finished, if the user wants to smoke again (for example, by touching the key or performing a pumping action to "wake up" the electronic smoking set), the electronic smoking set enters the preheating program 10 again and starts to execute the temperature control method of the heating element of the present embodiment again.

According to the present embodiment, an electronic smoking article includes a heat-generating body, a processor, and a storage medium storing a computer program.
