Detailed Description
In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is to be understood that the drawings in the following description are merely exemplary of the invention and that other drawings and embodiments can be derived by those skilled in the art without undue burden. The designation of the design orientation merely indicates the relative positional relationship between the respective members, not the absolute positional relationship.
Example one
According to a first aspect of the present invention, there is provided a method for starting measurement of smoke temperature of a heated cigarette, as shown in fig. 1, which is a flowchart of the method for starting measurement of smoke temperature of a heated cigarette, and includes:
step S101: and collecting temperature data of the cigarette core section in the preheating process, calculating the point position with the fastest temperature change on the cigarette core section, and defining the point position as a reference position.
In the embodiment of the invention, the smoke temperature is detected in a simulated suction mode, and the artificial suction effect is simulated; based on the central heating mode, the smoke temperature of the cigarette which is not combusted during heating is optimally measured, so that the optimal smoking time of the heated cigarette is effectively determined.
Based on the conventional heating cigarette, the judgment condition for determining the smoking time is the preheating time, the smoking state is the smokable state after the preheating is finished, but the temperature in the core section of the cigarette cannot be judged, and the heated states of the cigarette branch sections of different cigarettes have obvious difference under the execution standard of the same preheating program.
In the embodiment of the invention, the temperature data of the cigarette core section is acquired by the temperature measuring couples, specifically, a plurality of temperature measuring couples can be arranged in parallel at equal intervals and distributed along the axial direction of the cigarette, and the end parts of the temperature measuring couples are flush, so that the insertion depths of the temperature measuring couples when the temperature measuring couples are inserted into the cigarette core section are always kept consistent.
The insertion depth of the temperature measurement couple is calculated based on the heating appliance and is defined as the temperature measurement depth, and the starting point of the calculation of the temperature measurement depth is the outer surface of the shell at the notch. The temperature measuring depth of the invention can be a fixed value, namely the distance from the surface of the appliance shell to the surface of the heating needle, and the distance is calculated along the radial direction. The temperature measuring couple is vertically inserted into the cigarette core section and can be close to the heating needle.
In the embodiment of the present invention, when determining the reference position, the method specifically includes:
predefining temperature measurement intervals and temperature measurement depths;
temperature measuring points are arranged at equal intervals along the axial direction of the cigarette core section, and the temperature measuring depths are the same;
acquiring temperature data on each temperature measuring point position within the preheating time, and drawing a temperature change curve according to the temperature data;
and calculating and drawing a first-order derivative curve of the temperature change curve, and taking a point position corresponding to the maximum value as a reference position.
In the embodiment of the invention, the temperature measurement distance can reflect the density of the temperature measurement points, and can be set according to actual conditions, and the temperature measurement depth is fixed. A plurality of temperature measuring couples can be adopted to measure the temperature simultaneously, so that the temperature acquisition efficiency is improved, but the plurality of temperature measuring couples can possibly influence the heat diffusion to a certain extent and influence the temperature change of the cigarette core; and a single temperature measuring couple can be adopted to sequentially measure at different positions, so that the detection error can be effectively reduced.
In a specific example, according to the characteristics of a central electric heating mode, the heating appliance shell is subjected to a narrow groove treatment, the groove width is 1mm, and a thermocouple is conveniently inserted into a cigarette core. According to the length of the cigarette core section, 8-channel micro thermocouple clamps are adopted, thermocouples are respectively inserted at positions 1mm, 3mm, 5mm, 7mm, 9mm, 11mm, 13mm and 15mm away from the air inlet end face of the cigarette core, as shown in fig. 7, the insertion depth is 2.85mm (close to a heating needle), the cigarette core temperature collection density of 2mm of axial position interval is realized, and the temperature curves of different cigarette core positions in the preheating time are obtained.
Establishing a coordinate system by taking the time as an abscissa and the temperature of the cigarette core as an ordinate, and drawing a temperature change curve, as shown in fig. 5; a coordinate system is established by taking time as an abscissa and a first derivative of the temperature change curve as an ordinate, and a first derivative curve of the temperature change curve is drawn, as shown in fig. 6.
The result shows that the temperature rise rate is fastest at the position of 11mm, the reaction is most sensitive, so the suction time is determined by taking the temperature at the position as a reference, and the temperature of the cut tobacco is about 47 ℃ (mean value). Namely, when the temperature of the tobacco core at the position 11mm away from the air inlet end face of the tobacco reaches 47 ℃, the simulated smoking can be started.
Taking the temperature measurement point at the position of 11mm as an example for explanation, in the process of one experiment, the abscissa when the maximum value of the derivative occurs is 48, and the corresponding value of the first derivative is 9.90996, based on the uniformity of the time line, when the abscissa is 48, the temperature value at the time when the temperature change is the maximum can be correspondingly found out to be 45.99493 in the temperature change curve, so that the temperature value at the position of 11mm when the temperature change is the fastest can be 46, that is, the reference temperature at the position of 11mm is 46 ℃.
It can be understood that data of a single experiment is prone to errors, and therefore, multiple experiments should be performed on the reference position and the reference temperature to obtain average data so as to optimize the data.
Step S102: and measuring the temperature of the reference position for multiple times, calculating a temperature mean value corresponding to the fastest temperature change at the reference position, and defining the temperature mean value as the reference temperature.
In the embodiment of the present invention, multiple experiments may be performed, the reference temperature at the reference position is repeatedly detected, an effective average value is obtained, and the determining data is optimized, specifically including:
setting a plurality of groups of experiments to be carried out simultaneously, and monitoring the temperature change of the cigarette core in real time at the reference position corresponding to each group;
when the base line balance of a certain group is detected, preheating is started to acquire the data of the cigarette core temperature;
sequentially acquiring temperature values when the temperature at the reference position of each group changes fastest;
and counting and calculating the average value of the temperatures at the reference positions in various experiments when the temperature changes fastest, and defining the average value as the reference temperature.
In the embodiment of the present invention, it can be seen from fig. 5 and 6 that the early waiting time is long, which is a waiting period of baseline balance, and data acquisition can be performed only after the baseline balance. It can be understood that the delay waiting time after the baseline balance can be set for each group of experiments, so that the preheating start of each group of experiments is asynchronous, and the influence between groups is reduced. And sequentially acquiring the temperature data of each group, and performing data processing to obtain a temperature mean value.
It will be appreciated that for values that are clearly not reasonable when calculating the mean value of the temperature, it can be directly discarded. Further, the maximum value and the minimum value may be discarded before the mean value is obtained.
Based on the actual condition, namely when the temperature of the cigarette core reaches 47 ℃, the smoking can be started, the smoking is simulated through the smoking system, and the smoke temperature is detected and recorded.
Step S103: and determining a reference position in the simulation system, and monitoring the temperature of the cigarette core at the reference position in real time after preheating is started.
In the embodiment of the invention, the simulation system specifically comprises a heating smoking set, a suction system and a temperature measurement component, wherein a cigarette in the heating smoking set is butted with the suction system, the effect of manual suction is simulated through the suction system, and the temperature measurement component is used for detecting the temperature of a cigarette core and the temperature of smoke.
In the embodiment of the invention, the self-starting of the suction system can be triggered by determining the reference position corresponding to the heating appliance in the current simulation system according to the relative position relationship between the reference position and the cigarette core section and the heating needle and arranging the temperature measuring couple at the reference position.
It can be understood that the heating device used in the current simulation system and the heating device used for collecting the cigarette core segment in the preheating process should be the same product, and the model, the parameters and the like should be basically consistent, and the reference position based on the heater has uniformity. The reference position on the heating appliance used in the simulation system can be quickly determined, and a temperature measuring couple is arranged at the reference position to judge the suction time based on the internal temperature of the cigarette core.
In the embodiment of the invention, the feedback signal of the temperature measurement couple at the reference position can be used as the trigger condition of the pumping system to control the starting of the pumping system, so as to effectively simulate the real pumping flow and the pumping effect.
The temperature measuring couple and the preheating system at the reference position can be set to be started synchronously, or the temperature detection can be started after the temperature measuring couple is inserted, and a feedback signal is sent out. After the preheating system is started, the temperature measuring couple at the reference position can monitor the temperature of the cigarette core at the reference position in real time; when the temperature detected by the temperature measuring couple reaches a set value, a feedback signal can be sent to control the self-starting of the suction system.
It will be appreciated that the feedback signal should include at least a steady state signal to which the aspiration system is not responsive, i.e. not self-priming; the pumping system responds to a self-priming signal, i.e., self-priming.
Step S104: when detecting that the temperature of the cigarette core reaches the reference temperature, starting the suction system, detecting and recording the temperature of the smoke.
In the embodiment of the invention, the temperature measuring component comprises two independent temperature measuring areas, namely, a cigarette core section for heating the non-burning cigarette and the outer side of a filter tip for heating the non-burning cigarette, and the temperature measuring couples are correspondingly arranged. The temperature measurement galvanic couple outside the filter tip is used for detecting the temperature of flue gas, through the simulation suction experiment of suction system, can detect out the flue gas temperature in the suction process. Furthermore, the validated smoke temperature detection data can be used as basic parameters of subsequent experiments, for example, when the cooling effect of the cooling section of the heated cigarette is measured, the real cooling effect of the cooling section can be detected by accurate and valid smoke temperature data.
Specifically, after preheating is started, the temperature measuring couple at the reference position can monitor the temperature of the cigarette core section in real time:
when the temperature of the cigarette core is detected to be lower than the reference temperature, the suction system does not respond, and the smoke temperature measuring couple can be in a standby state;
when the temperature of the cigarette core reaches the reference temperature, the suction system is started automatically, the smoke temperature measuring couple starts to detect the smoke temperature at the filter tip end, and the detected smoke temperature is recorded.
Furthermore, the starting temperature can be preset, the starting temperature is lower than the reference temperature, and when the temperature of the cigarette core is detected to rise to the starting temperature, the smoke temperature measuring couple can be opened for temperature detection; partition recording may be performed for the detection data. And after the temperature of the cigarette core is detected to reach the reference temperature, the detected smoke temperature data is recorded in an effective manner.
The smoking times of a single heated cigarette are limited, and when the heated cigarette does not separate out smoke, the detection value of the temperature measuring couple at the filter tip basically tends to a stable state, so that the temperature measuring significance is not achieved.
The detected smoke temperature data can be associated and bound with the reference temperature, and has comparison significance in the use process of the same heating appliance, namely, the detected smoke temperature data can be compared with the smoke temperature data detected in a suction simulation experiment during conventional preheating starting, and the fluctuation and deviation of the smoke temperature are compared.
It will be appreciated that for a heating appliance, the reference position may vary with the shape, length, power, etc. of the heating needle, but the reference temperature should remain substantially constant, with empirical reference to historical data.
Based on the steps of the method, in a specific example, a simulated suction experiment is carried out by taking 47 ℃ as a reference temperature, and the change of the smoke temperature detection during suction is shown; and compared to the change in smoke temperature detection at suction initiated at regular preheat times. The relative standard deviation can be calculated for comparison.
When the temperature of the cigarette core reaches 47 ℃, the smoking is started to measure the temperature of 8 mouths of smoke
The smoke temperature of 8 mouths is measured by starting suction after the appliance is preheated for 12 seconds
According to the experimental data surface, the starting stability of the mode of starting by using the cigarette core temperature is better than that of the preheating time, so that the accuracy of measuring the smoke temperature of the heated cigarette is effectively improved, and the measurement of the cooling effect of the filter stick material of the heated cigarette and the evaluation of the quality of the heated cigarette are facilitated.
