Description
Technical Field
The invention relates to the field of a detection method of smoke temperature of cigarettes, in particular to a smoke temperature detection and analysis method of heating non-combustible cigarettes.
Background
At present, the heating of non-combustible cigarettes is similar to that of conventional cigarettes, and the heating of cigarettes produces aerosols. The user inhales the aerosol by drawing the heated non-combustible smoke, thereby completing the drawing of the heated non-combustible smoke. Unlike conventional cigarettes, however, the non-combustible cigarette is heated by a heating means without burning, so that the non-combustible cigarette can form an aerosol.
The non-combustible heating smoke forms aerosol after being heated, and the non-combustible heating smoke cannot burn after being heated, so the requirement on the temperature of the smoke of the non-combustible heating smoke after being heated is often strict. The heating non-combustible cigarette is generally divided into a smoking section, a cooling section and a filtering section, after the heating non-combustible cigarette is heated, the temperature of smoke at the joint between two adjacent sections is often required to be lower than a certain value, otherwise, the smoking experience of a user who heats the non-combustible cigarette is influenced, and the user is possibly scalded during smoking. Particularly, after the non-combustible cigarette is heated, the heating temperature in the non-combustible cigarette is as high as 300-350 ℃, and the heating mode is mainly baking heating, so that the heat is not easily taken away by smoke, if the surface temperature of the product is easily too high, the experience of consumers is finally influenced, and even the risk of scalding is brought, so that the temperature control of each section of the non-combustible cigarette is particularly important.
However, in the prior art, there is no method for detecting the temperature of the flue gas during combustion, which is effective for heating non-combustible smoke. In order to enable the heating non-combustion cigarette to have better user experience after the manufacturing is finished, the existing heating non-combustion cigarette manufacturers evaluate the temperature of the heating non-combustion smoke in a mode of smoking the heating non-combustion cigarette to be detected through sensory evaluation, and judge the temperature of the heating non-combustion smoke according to the actual experience of the smoker, so that the structure of the heating non-combustion cigarette is adjusted.
This detection method is not only costly, but also results in poor evaluation results due to individual differences among evaluators.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.
It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Referring to fig. 1 to 5, a method for detecting and analyzing a temperature of a smoke heated without combustion according to a preferred embodiment of the present invention will be described in detail below, wherein the method for detecting and analyzing a temperature of a smoke heated without combustion includes the steps of:
s1; heating at least one smoking section 10 to be tested which is not burning smoke;
s2; sucking the to-be-detected heating non-combustible smoke butted with the constant current device at preset time intervals by using the constant current device;
s3; collecting the smoke temperature of at least one temperature measuring point on the heated non-combustible smoke to be measured during each smoking so as to form smoke temperature data of the corresponding temperature measuring point; and
s4; and analyzing the temperature data, and conjecturing the temperature parameters of the corresponding temperature measuring points of the to-be-measured heating non-combustible smoke.
Specifically, in the step S1, the smoking segment 10 heated by the non-combustible smoke may be heated by a heating means. Preferably, the detection of the smoke temperature of the temperature measuring point on the heated non-combustible smoke to be detected is performed by a temperature measuring needle. The temperature measuring needle is inserted in the radial direction of the to-be-measured heating non-combustible smoke, and the insertion depth is 3-4 mm. By controlling the depth within this range, it is possible to effectively prevent the deviation of the results of the flue gas temperature test due to the positional error of the heating means with respect to the heated non-combustible smoke.
It is worth mentioning that, in the step S3, the detected temperature measurement point of the non-combustible heating smoke is selected from: at least one of the cooling section 20, a junction between the cooling section 20 and the filtering section 30, and an end of the filtering section 30, as shown in fig. 1.
By detecting the smoke temperature of the cooling section 20, it can be estimated whether the temperature of the smoking section 10 is high enough to volatilize aerosol of a corresponding concentration when the heated non-combustible smoke is smoked by the user. Once the smoke temperature of the cooling section 20 is too low, the temperature to which the smoking section 10 is heated will tend to cause the smoke concentration to be below a predetermined value, which directly affects the smoking experience of the user. It is worth mentioning that when the flue gas temperature of the cooling section is detected, the flue gas temperature of the cooling section 20 can be detected by inserting the temperature measuring needle into the joint of the two cooling sections forming the cooling section 20.
In addition, it can be determined whether the temperature of the smoke is reduced to a value below a predetermined temperature value after the temperature of the smoke formed by volatilization is reduced through the temperature reduction section 20 after the smoke generation section 10 is heated by detecting the temperature of the smoke at the joint between the temperature reduction section 20 and the filter section 30. It will be understood that if the temperature of the smoke at the connection between the temperature reduction section 20 and the filter section 30 where the heat does not burn the smoke is too high, the subsequent user will be burned by the high temperature of the smoke when the filter section 30 is sucked.
In addition, it can be understood that, by detecting the smoke temperature at the end of the filter segment 30, it can be directly judged whether the smoke temperature formed after the non-combustible heating smoke is heated can scald the user.
It can be understood that the invention can objectively and generally judge whether the heating non-combustion smoke meets the requirement by the detection method for the smoke temperature. And in the detection process, the heating non-combustible smoke to be detected does not need to be sucked manually. Therefore, the method for detecting and analyzing the temperature of the smoke of the heating non-combustible smoke can not cause harm to human bodies in the process of detecting the temperature of the smoke of the heating non-combustible smoke; in addition, by the method for detecting and analyzing the temperature of the smoke of the heating non-combustible smoke, the efficiency and the accuracy of the detection of the temperature of the smoke of the heating non-combustible smoke can be effectively improved.
In addition, in the step S4, the temperature parameters of the temperature measuring points include, but are not limited to, the temperature of the temperature measuring point, the first three temperature measuring points, and the single smoke temperature.
Further, in step S4, the step of estimating the maximum temperature value of the corresponding temperature measurement point of the to-be-measured non-combustible heated smoke according to the temperature data includes the following steps:
s41; and determining the smoke temperature of the temperature measuring point according to the size between the smoke temperature of the temperature measuring point measured by the suction of the previous preset times and the smoke temperature of the temperature measuring point measured by the suction of the next preset times and the smoke temperature of the temperature measuring point measured by the suction of other times. Preferably, the smoke temperature of the temperature measuring point, the smoke temperature of the first three temperature measuring points and the smoke temperature of the single-mouth smoke are determined according to the smoke temperature of the temperature measuring point measured by the first 3 times of suction and the smoke temperature of the other temperature measuring points measured by the last 3 times of suction.
Specifically, if the temperature of the first three times is highest, the average of the peak temperatures of the first three times is selected as the temperature of the temperature measuring point.
If the curve shows the trend of higher in the middle and lower in the two ends, the peak values of the peaks of the first three times and the last three times are removed, and the average value of the peak values of the middle peaks is selected as the temperature of the temperature measuring point.
For example, in one embodiment, when the smoke temperature of the non-combustible heating smoke H and the non-combustible heating smoke N are detected by the above method, the smoke temperature is collected every 13mS at the junction between the temperature reduction section 20, the temperature reduction section 20 and the filter section 30, and the end of the filter section 30, as shown in fig. 2 and 3. Furthermore, the temperature of the smoke at the junction between the smoking section 10 and the cooling section 20, the junction between the cooling section 20 and the filter section 30, and the end of the filter section 30, which heat up non-combustible smoke, can also be determined at each puff, as shown in fig. 4 and 5.
According to the step S41, it can be further determined that the maximum temperature value of the temperature measuring point can be shown in table 1 below
Table 1: temperature values of various temperature measuring points for heating non-combustible smoke
| Temperature (. degree.C.) | |
|
|
| Heating non-combustible smoke H | 51.70 | 63.53 | 154.70 |
| Non-combustible by heating N | 56.70 | 56.77 | 140.28 |
It is worth mentioning that the smoke temperature of the first three mouths has a great influence on the smoking feeling of the whole smoke. Therefore, when the temperatures of the temperature measuring points are determined in step S4, the temperatures of the respective temperature measuring points at which the non-combustible smoke is heated can be measured more accurately.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
