Against this background, a new type of tobacco product, heated cigarettes (or heated non-burning tobacco products), has gradually emerged and has been widely welcomed by the market. It is mainly a product that allows users to inhale nicotine and other substances in tobacco by means of atomization and other means. In the continuous evolution of heated cigarette technology, achieving high-precision temperature control is not only a breakthrough in technology, but also a reflection of a deep understanding of consumer experience. In order to ensure that the taste, aroma and nicotine delivery of each puff of smoke remain highly consistent, various existing technologies continue to try to improve the measurement accuracy and control accuracy of temperature sensors, in order to give consumers a stable and satisfactory smoking experience.
[0003] However, the temperature control curve of the current aerosol generating device is a better heating curve that is gradually explored by a certain heated cigarette on a certain aerosol generating device based on a normal environment (25°C room temperature) and relying on manual smoking. Once an aerosol generating device is replaced with a cigarette, or a cigarette is replaced with an aerosol generating device, a new heating curve needs to be explored again. Currently, there is a lack of efficient professional testing equipment to achieve batch testing of the optimal heating temperature curve of the aerosol generating matrix. Summary of the invention

It provides a constant temperature box with a wide range of temperature field distribution, which can complete the collection of multiple heating temperature test results in one test, eliminating the preparation time required to readjust the heating temperature and wait for the temperature field to stabilize when testing different temperatures in the past. The heating test array can be heated to different discrete temperatures in the constant temperature box. As long as the temperature in each sample chamber is accurately measured, a wide range of test data can be quickly obtained. In the subsequent test data sorting process, the test data at a specific temperature can be obtained by interpolation. Compared with the previous solution that requires accurate adjustment of the constant temperature box temperature, the experimental efficiency is significantly improved. In addition, the sample chamber in the heating test array is small in size, which saves test samples and can also simulate the actual heated cigarette size and the state of heating in the heated smoking device.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.
[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0030] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0031] The present invention provides an embodiment of an aerosol generating substrate heating test system, specifically, as Figure 1 As shown, it includes a test recorder 9, a constant temperature box 1 and a heating test array 6, the heating test array 6 includes a plurality of substrate heating container units 6a, 6b, 6c, 6d, the test recorder 9 includes a control system and a human-computer interaction system, the substrate heating container units 6a, 6b, 6c, 6d include sample chambers 61a, 61b, 61c, 61d, air inlet pipes 62a, 62b, 62c, 62d, and air outlet pipes 63a, 63b, 63c, 63d and thermocouples 64a, 64b, 64c, 64d, air inlet pipes 62a, 62b, 62c, 62d, sample chambers 61a, 61b, 61c, 61d, and air outlet pipes 63a, 63b, 63c, 63d are connected in sequence; thermocouples 64a, 64b, 64c, 64d are arranged in sample chambers 61a, 61b, 61c, 61d, and are connected to the test recorder 9.
[0032] It should be noted that the control system accurately controls the heating conditions in the heating test array 6 by preset programs or user-defined parameters to ensure the consistency and repeatability of the experiment. Through the human-computer interaction system, the user can set experimental parameters, monitor the experimental process, download and analyze experimental results, etc. The sample chamber is used to place the matrix sample to be tested, and the air inlet duct introduces clean air or inert gas as a carrier gas to help carry the aerosol generated by heating out of the sample chamber, and the air outlet duct is used to collect these aerosols for subsequent analysis and measurement. Thermocouples are directly installed in the sample chamber as temperature sensors, accurately measure the actual temperature during the heating process, and feed this information back to the control system of the test recorder to achieve closed-loop control of temperature. Through accurate control system and constant temperature box design, the system can ensure that the heating conditions of each experiment are consistent, thereby greatly improving the accuracy and repeatability of experimental data.
[0033] In the embodiment of the present invention, the air outlet pipes 63a, 63b, 63c, and 63d are connected to one or more cigarette holders 11 for one or more tasters to perform sensory tests and input sensory test results through the human-computer interaction system. The provision of multiple cigarette holders allows multiple tasters to perform sensory tests simultaneously or sequentially, thereby improving test efficiency and accuracy. After completing the sensory test, the taster can input his or her own test results, including scores and descriptions of various sensory indicators, through the human-computer interaction interface (such as a touch screen, keyboard, etc.) of the human-computer interaction system.
[0034] In the embodiment of the present invention, the aerosol generating substrate heating test system further comprises a cold trap array 7, the cold trap array 7 comprises a plurality of aerosol cold trap units 7a, 7b, 7c, 7d, and the aerosol cold trap units 7a, 7b, 7c, 7d are connected to the gas outlet pipes 63a, 63b, 63c, 63d (such as Figure 6 As shown). It should be noted that when the high-temperature aerosol passes through the cold trap array 7, the water vapor and other volatile components therein will condense into droplets due to the sudden drop in temperature, and at the same time, the solid particles will be deposited on the surface of the cold trap array 7 due to the effect of surface tension. In this way, the cold trap array 7 can effectively separate and collect different components in the aerosol, providing valuable samples for subsequent analysis. On the other hand, the number and arrangement of the aerosol cold trap units can be adjusted according to the experimental requirements to meet the requirements of different matrices and different test conditions.
[0035] In the embodiment of the present invention, Figure 2As shown, the thermostat 1 has a first electric heater 2 and a second electric heater 3, the target heating temperature of the first electric heater 2 is higher than the target heating temperature of the second electric heater 3, and the first electric heater 2 is located above the second electric heater 3; the thermostat has a first temperature sensor 4 near the first electric heater 2 and a second temperature sensor 5 near the second electric heater 3. The first electric heater 2 and the second electric heater 3 are respectively heated and controlled by the temperature control system to heat the hot bath liquid in the thermostat 1 and maintain it at a stable temperature. The temperature near the first electric heater 2 (for example, 380°C) is set to be higher than the temperature near the second electric heater 3 (for example, 220°C), because of this, the hot bath liquid in the thermostat 1 forms a temperature field from 220°C to 380°C from bottom to top, and the internal convection caused by the cold upper liquid and the hot lower liquid will not cause the internal temperature field of the thermostat 1 to be disordered. Through the use of two electric heaters with different target heating temperatures and two temperature sensors, the temperature of different areas in the thermostat can be accurately controlled to meet different experimental or storage requirements. The layout of the upper and lower layers of electric heaters helps to form a temperature gradient, making the temperature distribution inside the constant temperature box more uniform and reducing temperature fluctuations and temperature differences.
[0036] In the embodiment of the present invention, the heating test array 6 is connected to the control system, and the heating test array 6 is lifted and lowered in the thermostat 1 by the lifting device under the control of the control system. It should be noted that after the lifting device lifts the heating test array 6 from the thermostat 1, the sample therein can be replaced. In order to improve efficiency, the cleaning of the sample chamber and the test can be carried out simultaneously, that is, the sample is placed in the spare sample chamber in advance, and then the last batch of sample chambers are quickly replaced to continue the test, and the last batch of sample chambers are cleaned and new samples are placed in the chamber for standby. After the lifting device sinks the heating test array 6 into the thermostat 1, the hot bath liquid quickly heats up the samples in each sample chamber 61a, 61b, 61c, and 61d. Since the hot bath liquid has a temperature field from 220°C to 380°C from bottom to top, each sample chamber is heated to a different temperature, for example, the sample chambers 61a, 61b, 61c, and 61d are 230°C, 272°C, 304°C, and 345°C, respectively. When the thermocouples 64a, 64b, 64c, and 64d are all in a stable temperature state (for example, the temperature rise rate is less than 2°C / s) or after a fixed heating time (for example, 15s) is completed, the puff indicator light is on, and the smoker or the automatic smoking machine 10 can perform a puff test.
[0037] It should be noted that the lifting device is a mechanical or electric device used to realize the vertical movement of the heating test array in the constant temperature box. Through the lifting device, the relative position of the heating test array 6 and other components inside the constant temperature box 1 (such as temperature sensors, fans, etc.) can be adjusted to optimize the temperature distribution. The control system can automatically complete tasks such as temperature setting and lifting control, reducing manual intervention and improving test efficiency.
[0038] In the embodiment of the present invention, Figure 3 Shown and Figure 4 As shown, the probes of the thermocouples 64a, 64b, 64c, and 64d are arranged in the sample chambers 61a, 61b, 61c, and 61d. When the gas heating test array 6 is sunk into the constant temperature box 1, the control system notifies the smoke taster to conduct a sensory test or start the automatic smoking machine 10 to collect aerosol according to the recorded heating temperature and heating time in the sample chambers 61a, 61b, 61c, and 61d, and after the heating temperature stabilizes or the heating time reaches a preset value, through the human-computer interaction system.
[0039] It should be noted that when the heating test array 6 is sunk into the constant temperature box 1, the control system starts working. The control system first heats the matrix according to the preset experimental parameters (such as target heating temperature, heating time, etc.). During this process, the thermocouple probe continuously monitors the temperature in the sample chamber and feeds back the data to the control system in real time. The control system makes adjustments based on these data to ensure that the heating process is carried out according to the preset parameters. When the heating temperature is stable (that is, the temperature fluctuation is within a certain range), or the heating time reaches the preset value, the control system will make a judgment: if the experimental design requires sensory testing or aerosol collection after the temperature is stable, the control system will send a notification to the taster through the human-computer interaction system. After receiving the notification, the taster will perform sensory testing according to the standard process to evaluate the taste, aroma and other sensory characteristics of the aerosol generated by the heated matrix. If the experimental design requires automatic collection of aerosols after a specific heating time, the control system will start the automatic smoking machine. The automatic smoking machine 10 extracts the aerosol generated in the sample chamber at a set time point and under set conditions, and collects it into a dedicated collection device. The collected aerosol can be used for subsequent analysis and measurement, such as chemical composition analysis, particle size distribution measurement, etc.
[0040] In the embodiment of the present invention, Figure 5As shown, the aerosol generation matrix heating test system also includes an array frame 8, which is composed of a metal or alloy with a thermal conductivity of more than 20 W / m·K. The sample chambers 61a, 61b, 61c, 61d, the air inlet pipes 62a, 62b, 62c, 62d, the air outlet pipes 63a, 63b, 63c, 63d and the thermocouples 64a, 64b, 64c, 64d of each matrix heating container unit 6a, 6b, 6c, 6d are all fixed on the array frame 8. It should be noted that the selection of high thermal conductivity materials can ensure that heat can be quickly and evenly transferred to each matrix heating container unit. The metal or alloy material includes aluminum, copper, stainless steel and its alloy, etc., and has a hollow structure or a thinner outer wall to ensure that the heat energy of the hot bath liquid in the constant temperature box 1 can be effectively transferred to the aerosol generation mechanism in the sample chamber. The array frame 8 is provided with a plurality of brackets or slots for fixing the matrix heating container unit. The sample chambers 61a, 61b, 61c, 61d, the air inlet pipes 62a, 62b, 62c, 62d, the air outlet pipes 63a, 63b, 63c, 63d and the thermocouples 64a, 64b, 64c, 64d are installed on the array frame 8 by means of bolt connection, snap connection or welding.
[0041] Furthermore, the sample chambers 61a, 61b, 61c, and 61d can be detachably mounted on the array frame 8, and the outer contours of the sample chambers 61a, 61b, 61c, and 61d correspond to the inner contours of the mounting grooves on the array frame 8 to ensure both stable mounting and effective heat conduction. In order to increase the heat transfer area, the outer contours of the sample chambers 61a, 61b, 61c, and 61d have a plurality of heat conducting ribs (such as Figure 4 The sample chambers 61a, 61b, 61c, 61d are made of metal or alloy with a thermal conductivity of more than 20W / m·K, such as copper, aluminum or stainless steel with good thermal conductivity, and have a closed and thin outer wall to ensure that heat energy can be effectively transferred to the aerosol generation mechanism in the sample chambers 61a, 61b, 61c, 61d. The thermal ribs are a series of protrusions or rib-like structures on the outer contour of the sample chamber, which can enhance the thermal conductivity of the sample chamber, so that heat can be transferred to the sample faster and more evenly.
[0042] In the embodiment of the present invention, the air inlet pipe 62a, 62b, 62c, 62d or the air outlet pipe 63a, 63b, 63c, 63d has a high temperature resistant sealing head, the high temperature resistant sealing head has a threaded structure and a high temperature resistant silicone gasket, and the high temperature resistant sealing head is sealed and connected to the array rack 8 or the sample chamber 61a, 61b, 61c, 61d. It should be noted that the threaded structure enables the sealing head to be firmly connected to the corresponding interface of the air inlet pipe, the air outlet pipe, the array rack or the sample chamber.
[0043] Furthermore, the probes of the thermocouples 64a, 64b, 64c, and 64d are arranged in the sample chambers 61a, 61b, 61c, and 61d, and a hole can be punched on the high temperature resistant sealing head to lead out the temperature signal wire. In order to ensure the sealing of the high temperature resistant sealing head, the wire of the thermocouple is directly welded to the metal surface of the high temperature resistant sealing head, and the temperature signal is transmitted to the outside through the air inlet pipe or the air outlet pipe by utilizing the high temperature resistant seal.
[0044] In the embodiment of the present invention, the thermostat 1 is sealed with nitrogen, and the thermostat 1 contains a hot bath liquid, and the hot bath liquid uses a heat transfer oil above 400°C. The thermostat 1 contains a hot bath liquid. Since the heating temperature of the aerosol-generating substrate in the heated cigarette is usually between 250°C and 350°C, the maximum temperature that can be provided by the test equipment for the ideal heating conditions of the aerosol-generating substrate needs to reach 400°C. Conventional heat transfer oil is generally used under conditions below 300°C. Above 350°C, there is a risk of large-scale evaporation or fire, so this type of heat transfer oil cannot be directly used as the hot bath liquid of the present invention. On the one hand, the present invention uses a heat transfer oil (such as Clark RD-400 high-temperature heat transfer oil) that can operate at 400°C or above as a hot bath liquid to ensure that the thermostat can operate stably in a high-temperature environment and meet the application requirements of high-temperature performance testing, material heat treatment, etc. On the other hand, the thermostat 1 is sealed with nitrogen to isolate the air, effectively avoiding oxidation and deterioration of the heat transfer oil and affecting its performance.
[0045] The test system of the present invention can efficiently carry out research on the ideal heating curve of heated cigarettes. The test recorder 9 automatically records the heating temperature and heating time corresponding to each test, thereby improving the degree of automation of the test process. The test system is equipped with a cold trap array 7, which can correspond to the heating test array 6 and automatically collect samples required for subsequent component analysis one by one. By adopting the test system of the present invention, the test team has been able to complete the test data collection of 10 tobacco formulas per day instead of the original one.
[0046] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
