The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
FIG. 1 is a flow chart of a method for controlling the temperature of a cigarette that is not burned by heating according to an embodiment of the present invention;
fig. 2 is a schematic diagram of a temperature control method for a cigarette which is not burned by heating in the implementation process according to an embodiment of the invention.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
As shown in fig. 1 and 2, an embodiment of the present invention provides a temperature control method for a cigarette that is not burned by heat, comprising the steps of:
step S1, starting to heat the first stage on the first heated area and the second heated area which are not adjacent on the cigarette.
The first heated area and the second heated area on the cigarette are different heated areas on the outer side surface of the cigarette, and the non-adjacency means that the first heated area and the second heated area are not continuous areas on the surface of the cigarette, but surface areas which are not directly heated are arranged between the first heated area and the second heated area. Therefore, the cigarette can be heated unevenly by respectively and independently heating the first heated area and the second heated area.
The first heating area and the second heating area can be provided with a plurality of heating sheets, specifically, a plurality of groups of heating sheets can be arranged on the cigarette which is not heated and combusted, so that each group of heating sheets respectively and independently heats only one heating area, and the non-uniform heating of the plurality of heating areas is realized through the independent control of each heating sheet.
It should be noted that, in the whole process of preheating and smoking cigarettes, one or more heating sheets can be controlled to heat one or more heated areas, and the rest heating sheets do not participate in the heating operation all the time, so that partial areas on the cigarettes are not heated all the time, the non-uniform heating of the cigarettes is realized, and the purpose of avoiding excessive heating of the cigarettes is achieved.
Further, before step S1, the method further includes:
step S101, detecting whether the temperature of the air inlet side of the heated non-combustible cigarette reaches or exceeds a prepared air inlet temperature value; if yes, go to step S102; if not, the process proceeds to step S103.
The preliminary inlet air temperature value may be 12 to 25 ℃, and is preferably 15 ℃ in the present embodiment.
Step S102, setting the first-stage preset time length as a first preset time length t of the first stage I-1 。
Step S103, setting the first-stage preset time length as a second preset time length t of the first stage I-2 And the second preset time t I-2 Reaches or exceeds the first preset time t I-1 。
Wherein the steps S101 to S103 are executed before the non-combustion preheating.
It should be noted that the preset time of the first stage represents the total time of the cigarette preheating stage before smokingLong. The temperature detection of the air inlet side can be the detection of the ambient temperature, if the detected air inlet temperature value reaches or exceeds 15 ℃, for example, in hot summer, the smoking environment is high, and at the moment, the cigarettes can reach the smoking temperature without being preheated for a long time. If the detected air inlet temperature value is less than 15 ℃, for example, in cold winter, the environment temperature for smoking is low, and at the moment, cigarettes need to be preheated for a long time to reach the smoking temperature; alternatively, in the case that the detected intake air temperature value is less than 15 ℃, t can be prolonged 1 Time, i.e., increasing the operating time of the first heated area, to achieve increased heat and thus pumping conditions. Therefore, the cigarette can be preheated to the standard smoking temperature no matter under the condition of overhigh or overlow ambient temperature, the normal heating decomposition of the tobacco material is ensured, and the influence of setting fixed preheating time on the decomposition of the tobacco material due to the fact that the ambient temperature condition cannot be compensated is avoided.
For convenience of description, the cigarette is only smoked in an environment of above 15 ℃ in this embodiment, that is, the preset time period of the first stage is t I-1 As shown in fig. 2.
Step S2, judging whether the duration of heating the first heated area reaches or exceeds a first duration t 1 (ii) a If so, the process proceeds to step S3.
Step S3, stopping heating the first heated area and keeping heating the second heated area.
Further, before step S2, the method further includes:
step S201, detecting whether the heated temperature of the first heated area reaches or exceeds a third temperature value T3; if so, the process proceeds to step S202.
The third temperature value T3 may be 150 ℃ to 200 ℃, and is preferably 180 ℃ in this embodiment. As shown in FIG. 2, the time corresponding to the intersection of the temperature change curve of the first heated area and the temperature change curve of the second heated area is t 1 The temperature is 180 ℃, indicating that at this intersection, the first heated zone ceases to be heated, while the second heated zone continues to be heated.
Further, as shown in FIG. 2, at t 1 To t I-1 Within the time period, the first heated area stops being heated, the second heated area is continuously heated, and partial heat of the second heated area is conducted to the first heated area, so that the temperature of the first heated area rises in a small range.
Step S202, stopping heating the first heated area, and keeping heating the second heated area.
Step S4, judging whether the duration of heating the second heated area reaches or exceeds the preset duration of the first stage; if yes, go to step S5; if not, heating of the second heated zone is maintained.
And step S5, stopping heating the second heated area.
Therefore, the preheating of the cigarettes before smoking is completed by respectively and independently heating the first heated area and the second heated area on the cigarettes in different time periods, and meanwhile, the situation that harmful substances are generated due to excessive heating of the cigarettes to influence the follow-up smoking taste can be avoided.
Further, before step S4, the method further includes:
step S401, detecting whether the heated temperature of the second heated area reaches or exceeds a fourth temperature value T4; if so, the process proceeds to step S402.
The fourth temperature value T4 may be 180 ℃ to 230 ℃, and in this embodiment, the fourth temperature value T4 is 210 ℃.
And S402, stopping heating the second heated area.
As shown in FIG. 2, the second heated zone is at time t I-1 The corresponding temperature is the fourth temperature value T4, which is 210 ℃. At the time t I-1 The first heated area is subjected to the heat transfer of the second heated area, and the temperature value is higher than 180 ℃ of the third temperature value T3 and lower than 210 ℃ of the fourth temperature value T4.
And step S6, starting to carry out second-stage heating on the second heated area of the cigarettes.
Wherein, the first stage is a cigarette preheating stage, and the second stage is a user smoking stage.
Further, after step S6, the method further includes:
step S61, detecting whether the heated temperature of the first heated area is less than a fifth temperature value T5; if yes, go to step S62; if not, the flow proceeds to step S63.
Step S62, heating the first heated area.
And step S63, stopping heating the first heated area.
The fifth temperature value T5 may be 170-230 ℃, and is preferably 210 ℃ in the present embodiment. In this embodiment, the fifth temperature value T5 may be the same as the fourth temperature value T4, and both are 210 ℃.
Wherein, because the second heated area is heated continuously to can be with this first heated area of partial heat transfer, at this moment, even first heated area does not receive external heating, still can keep higher temperature, thereby can guarantee the normal thermal decomposition of tobacco material, and then guarantee user's taste of sucking.
It should be noted that the above steps S61-S63 may not be performed, i.e., the first heated area is t 1 -t 2 While the heating is in the inactive control state, the process proceeds from step S6 to step S7.
Step S7, detecting whether the heated temperature of the second heated area reaches or exceeds a first temperature value T1; if yes, go to step S8; if not, the flow proceeds to step S9.
Step S8, stop heating the second heated zone, and re-execute step S7.
Step S9, maintaining heating of the second heated area.
Wherein, the first temperature value T1 can be 200-250 ℃; in this embodiment, 230 ℃ is preferable.
As shown in fig. 2, at time t I-1 To t 2 Meanwhile, as the second heated area is continuously heated through the controllable heating process, the corresponding time t is t when the temperature reaches 230 DEG C 2 When the second heated area is heated for a second time period t or longer to avoid the second heated area from decomposing harmful substances due to excessive heating 2 At this time, the pair of the first and secondHeating of the two heated areas is started, and heating of the first heated area is started.
Step S10, judging whether the duration of heating the second heated area reaches or exceeds a second duration t 2 (ii) a If yes, go to step S11; if not, heating of the second heated zone is maintained.
And step S11, stopping heating the second heated area, and starting and keeping heating the first heated area.
At this time, since the second heated area has been heated for a long time, the tobacco material at the second heated area risks being excessively decomposed to generate harmful substances, and for this reason, in the embodiment, the second time period t may be elapsed 2 And then, the second heated area is stopped being heated continuously, and the first heated area is heated instead, so that the decomposition efficiency of the tobacco material positioned in the first heated area is improved, the cigarette is prevented from being excessively heated, the cigarette is ensured to provide uniform smoke, and the smoking taste is ensured.
Further, in step S11,
the second heated area is at t 2 -t II The period may be in an inactive control state. The inactive control state means that the controller controls whether the second heated area is heated or not according to the time signal, but not according to the temperature signal.
It should be noted that, in step S11, the temperature of the second heated area may also be actively controlled, specifically:
step S1101, detecting the second heated area at t 2 -t II Whether the temperature during this period is less than a sixth temperature value T6; if yes, go to step S1102; if not, the process proceeds to step S1103.
Step S1102 is heating the second heated region, and step S1101 is repeatedly performed.
Step S1103, the heating of the second heated zone is stopped, and step S1101 is repeatedly executed until step S15.
The sixth temperature value T6 may be 150 ℃ to 250 ℃, and is preferably 210 ℃ in the present embodiment.
Step S12, detecting whether the temperature of the first heated area reaches or exceeds a second temperature value T2; if yes, go to step S13; if not, the flow proceeds to step S14.
Step S13, stopping heating the first heated zone, and repeatedly performing step S12.
Step S14, maintaining heating of the first heated zone.
Wherein, the second temperature value T2 can be 200-250 ℃; in this embodiment, 230 ℃ is preferred.
Step S15, judging whether the duration of heating the first heated area reaches or exceeds the preset duration of the second stage; if yes, go to step S16; if not, heating of the first heated zone is maintained.
And step S16, stopping heating the first heated area.
Compared with the prior art, the temperature control method for the cigarette which is not combusted by heating provided by the embodiment of the invention realizes non-uniform heating of different areas of the cigarette in different stages of the smoking process, reasonably adjusts the accumulated heating process of the tobacco material in the whole working stage, effectively avoids the problems of increase of harmful substances, poor consistency of smoke and the like caused by too early excessive heating of the cigarette, and influences the smoking taste; and the non-uniform heating control can also improve the energy utilization effect and reduce the heat dissipation.
Further, the method also includes:
step S17, during the heating work period, namely in the heating process of the first stage and the second stage, detecting whether the temperature of the air inlet side of the non-combustion cigarette reaches or exceeds the working air inlet temperature value; if so, the process proceeds to step S18.
Wherein the working inlet air temperature value may be 50 ℃.
Step S18, stopping heating the first heated zone and the second heated zone.
It can be understood that, during the smoking process, the high-temperature heat generated during the thermal decomposition of the tobacco material affects the temperature of the air inlet side of the cigarette which is not combusted, so that the temperature value detected by the air inlet side is higher than the ambient temperature, but when the temperature value of the air inlet side during the smoking exceeds the working air inlet temperature value by 50 ℃, the ambient temperature is too high or the internal temperature of the smoking set is too high, and at the moment, the heating of the first heated area and the second heated area can be stopped, so that the unpredictable risk is avoided.
Further, the method also includes:
step S19, in the heating process of the first stage and the second stage, detecting whether the temperature of the gas outlet of the cigarette which is not burnt reaches or exceeds a preset gas outlet temperature value; if so, the process proceeds to step S20.
The preset outlet temperature value can be 40-120 ℃, and can be set according to actual conditions. For example, the predetermined air-out temperature value may be 60 ℃ to 120 ℃ when the filter of a heated non-burning cigarette has a large draw resistance, and may be 40 ℃ to 100 ℃ when the filter is a low draw group filter.
Step S20, stopping heating the first heated zone and the second heated zone.
In the process of sucking, when the temperature of the air outlet side exceeds the preset air outlet temperature value, the user can have bad feeling of 'mouth burning', at the moment, the first heated area and the second heated area can be stopped being heated to avoid the temperature from excessively rising, and the sucking feeling of the user is ensured.
