[0002] Aerosol-generating products refer to products that can release aerosols. Currently common aerosol-generating products include tobacco products, which can generate aerosols for consumers to inhale after being ignited (or heated).

[0003] When consumers smoke tobacco products (including traditional cigarettes, heated cigarettes, etc.), especially heated cigarettes, they sometimes feel uncomfortable due to the high temperature of the smoke (i.e. aerosol), such as burning and hot smoke.

The aerosol temperature measuring device can more accurately measure the maximum temperature of the mainstream aerosol.

[0042] Please refer to Figures 1 to 4 This embodiment provides an aerosol temperature measuring device 100. In a specific embodiment, the aerosol temperature measuring device 100 is a smoke temperature measuring device for measuring the temperature of smoke generated by tobacco products. More specifically, the aerosol temperature measuring device 100 is used to measure the maximum temperature of mainstream smoke generated by igniting (or heating) tobacco products.

[0043] The aerosol temperature measuring device 100 includes a mounting member 10, a sealing member 20, and a temperature sensor 30. The mounting member 10 is provided with a sample mounting portion 11 and a suction mounting portion 12, wherein a sample mounting cavity 111 is provided in the sample mounting portion 11, a suction mounting cavity 121 is provided in the suction mounting portion 12, and a detection cavity 13 is also provided in the mounting member 10, wherein the detection cavity 13 connects the suction mounting cavity 121 with the sample mounting cavity 111. When the aerosol temperature measuring device 100 is used, a sample 200 is correspondingly mounted at the sample mounting portion 11, a suction device 300 is correspondingly mounted at the suction mounting portion 12, some components on the sample 200 are correspondingly inserted into the sample mounting cavity 111, and some components on the suction device 300 are correspondingly inserted into the suction mounting cavity 121. The suction device 300 forms a suction force on the side of the suction installation cavity 121, so that the aerosol generated at the sample 200 is sucked into the suction installation cavity 121 through the detection cavity 13, so as to simulate the process of smoking a cigarette. The sample 200 can be a traditional cigarette or a heated cigarette. For example, in one embodiment, the sample 200 is a heated cigarette 220 with a cigarette holder 210. The suction device 300 can be any device that can generate a suction force on the sample 200, such as a smoking machine, a suction machine, a smoke collector, etc.

[0044] A detection hole 15 is provided on the side wall 14 of the mounting member 10, and the detection hole 15 is communicated with the detection cavity 13. The sealing member 20 is mounted on the mounting member 10, and the temperature sensor 30 is connected to the sealing member 20, and the temperature sensor 30 extends into the detection cavity 13 through the detection hole 15. When the aerosol temperature measuring device 100 is used, the sample 200 is first ignited or heated, and then the suction device 300 forms a suction force on this side of the suction installation cavity 121, and the aerosol formed on one side of the sample installation cavity 111 is sucked into the suction installation cavity 121 through the detection cavity 13, and when the aerosol flows through the detection cavity 13, the temperature sensor 30 measures the temperature of the aerosol flowing through.

[0045] The detection hole 15 and the bottom surface 1111 of the sample installation cavity 111 are spaced apart from each other, and the distance between the central axis of the detection hole 15 and the bottom surface 1111 is less than 1.0 mm. In this way, the maximum temperature of the mainstream smoke can be measured more accurately. In this embodiment, when the sample 200 is installed in the sample installation part 11, the end face 2101 of the cigarette holder 210 abuts against the bottom surface 1111, and the filter outlet end face 2201 of the heated cigarette 220 is flush with the end face 2101. Therefore, when the sample 200 is installed in the sample installation part 11, the distance between the filter outlet end face 2201 and the central axis of the detection hole 15 is less than 1.0 mm. More preferably, in one embodiment, the central axis of the temperature measuring end 31 of the temperature sensor 30 is located on the same straight line as the central axis of the detection hole 15, so that when the sample 200 is installed on the sample mounting portion 11, the distance between the central axis of the temperature measuring end 31 and the filter outlet end face 2201 is less than 1.0 mm, thereby more accurately measuring the maximum temperature of the mainstream smoke.

[0046] It is understandable that in current technology, when measuring smoke, the distance between the cigarette sample insertion end and the thermocouple is usually 1-2 mm, and it is preferably recommended to place the thermocouple at the center of the inner circumference of the cigarette insertion port.

[0047] During the research and development and testing process, the inventors discovered that, regardless of whether it is a traditional cigarette or a heated cigarette, the mainstream smoke temperature field distribution presents the following pattern: in the axial direction, the mainstream smoke temperature at the cigarette filter outlet end face is the highest, and as the distance from the cigarette filter outlet end face increases, the mainstream smoke temperature decreases; when the temperature measurement site is 0.5 mm away from the cigarette filter outlet end face, the temperature measurement result decreases by approximately 0.35°C, and when the temperature measurement site is 1.0 mm away from the cigarette filter outlet end face, the temperature measurement result decreases by approximately 1°C.

[0048] In the aerosol temperature measurement device 100 provided in this embodiment, the detection hole 15 and the bottom surface 1111 of the sample installation cavity 111 are spaced apart from each other, and the distance between the central axis of the detection hole 15 and the bottom surface 1111 is less than 1.0 mm, so the maximum temperature of the mainstream smoke can be measured more accurately.

[0049] Furthermore, it is understandable that when the temperature measuring end of the temperature sensor contacts the end face of the cigarette filter outlet, the temperature of the cigarette filter is measured, not the temperature of the mainstream smoke. By inserting the temperature sensor 30 into the detection chamber 13 to detect the aerosol temperature, firstly, each time the sample 200 is inserted, it will not contact the temperature sensor 30, thereby not affecting the position of the temperature sensor 30, ensuring the accuracy of each detection; secondly, it can better simulate the flow environment of smoke in the consumer's mouth, more accurately feedback the temperature of the smoke that will cause damage to the oral area during the flow process, and measure the temperature of the mainstream smoke.

[0050] When measuring the flue gas temperature, the flue gas temperature at each position in the flue gas temperature measuring device will be different. Whether the temperature measuring end of the thermocouple is accurately positioned at the predetermined position is one of the key factors affecting the reliability of the measurement data. Based on this, before each mainstream flue gas temperature measurement, the temperature measuring end of the thermocouple needs to be accurately positioned as required. Since the above-mentioned accurate positioning requirements are extremely strict, very precise measurements or the use of relevant accurate positioning equipment are required, which is time-consuming and labor-intensive; and there are inevitably differences in accurate positioning when measuring different batches, resulting in errors between the measurement results of different batches.

[0051] Preferably, in one embodiment, the seal 20 is fixedly mounted on the mounting member 10, that is, the seal 20 and the mounting member 10 are fixedly connected to each other and cannot be disassembled. The temperature sensor 30 is fixedly connected to the seal 20, that is, the temperature sensor 30 and the seal 20 are also fixed and cannot be disassembled. The mounting member 10, the seal 20, and the temperature sensor 30 are fixed to each other as an integrated structure, and the position of the temperature sensor 30 will not change after the temperature sensor 30 is accurately positioned only once. Each time a measurement is performed, there is no need to perform complicated positioning work, and the measurement can be performed directly, which is convenient, fast, time-saving and labor-saving. In addition, the aerosol temperature measurement results of different batches of samples will not cause errors between the measurement results due to the slight differences in the positioning of the temperature sensor 30.

[0052] The sealing member 20 and the mounting member 10, and the temperature sensor 30 and the sealing member 20 can be fixed in any manner, such as glue fixing, hot-melt fixing, etc. It is only necessary to connect and fix the temperature sensor 30, the sealing member 20, and the mounting member 10 into an integrated structure.

[0053] Preferably, in another embodiment, the temperature sensor 30 is fixedly connected to the sealing member 20, that is, the temperature sensor 30 and the sealing member 20 are fixedly connected to each other to form an integral component and cannot be disassembled. The sealing member 20 is detachably mounted at the mounting positioning hole 16, and the temperature measuring end 31 of the temperature sensor 30 extends into the detection cavity 13 through the detection hole 15. In other words, the sealing member 20 is detachably connected to the mounting member 10, and the sealing member 20 is specifically detachably mounted at the mounting positioning hole 16 on the mounting member 10. Since the temperature sensor 30 and the sealing member 20 are an integral component, when the sealing member 20 is mounted on the mounting member 10, the temperature sensor 30 is also mounted on the mounting member 10 at the same time, and after the temperature sensor 30 is installed, the temperature measuring end 31 extends into the detection cavity 13 through the detection hole 15, so that when the aerosol flows through the detection cavity 13, the temperature sensor 30 can detect the corresponding temperature data. When the seal 20 is removed from the mounting member 10, the temperature sensor 30 will also be removed from the mounting member 10, thereby realizing the rapid removal of the temperature sensor 30. The temperature sensor 30 and the seal 20 are fixed to each other as an integral structure to form an integral component. The temperature sensor 30 only needs to be accurately positioned once during the installation of the temperature sensor 30 and the seal 20, and the position of the temperature sensor 30 will not change. Each time a measurement is performed, through the cooperation between the seal 20 and the mounting positioning hole 16, it is only necessary to insert the integral component formed by the temperature sensor 30 and the seal 20 into the mounting positioning hole 16, and insert the integral component from the mounting positioning hole 16 to the bottom to complete the positioning of the temperature sensor 30. There is no need to perform complicated positioning work, and the measurement can be performed directly, which is convenient, fast, time-saving and labor-saving. In addition, the aerosol temperature measurement results of different batches of samples will not cause errors between the measurement results due to the slight differences in the positioning of the temperature sensor 30. At the same time, since the sealing member 20 and the mounting member 10 are detachably connected, the temperature sensor 30 can be promptly disassembled and cleaned from the mounting member 10 after one (or more) measurements, thereby effectively preventing aerosol condensation on the surface of the temperature sensor 30, thereby better ensuring the sensitivity of the temperature sensor 30, and further ensuring the accuracy of the measurement results of the aerosol temperature measurement device 100.

[0054] The temperature sensor 30 and the sealing member 20 may be fixed in any manner, such as by gluing or hot-melting, etc. The temperature sensor 30 and the sealing member 20 only need to be fixed as one body, and no relative displacement will occur.

[0055] The sealing member 20 and the mounting member 10 may be connected in any detachable manner, for example, the sealing member 20 and the mounting member 10 may be connected in a snap-fit ​​manner, or in a plug-in manner, etc. It is sufficient that the sealing member 20 can be stably mounted on the mounting member 10 and can be removed from the mounting member 10 when removal is required.

[0056] Specifically, in one embodiment, the detection hole 15 and the temperature sensor 30 are both arranged along the radial direction of the mounting member 10 .

[0057] More preferably, in one embodiment, the distance between the central axis of the detection hole 15 and the bottom surface 1111 is not greater than 0.5 mm. In other words, the distance between the central axis of the detection hole 15 and the bottom surface 1111 is less than or equal to 0.5 mm, so that the maximum temperature of the mainstream smoke can be measured more accurately. Specifically, in one embodiment, the distance between the central axis of the detection hole 15 and the bottom surface 1111 is 0.5 mm.

[0058] During the research and development and testing process, the inventors also found that the mainstream smoke temperature field distribution of both traditional cigarettes and heated cigarettes shows the following pattern: radially, the mainstream smoke temperature is highest at the exact center of the cigarette (i.e., the center of the inner circle), and the mainstream smoke temperature decreases rapidly with increasing distance from the center; when the temperature measurement site is 0.1 mm away from the exact center of the cigarette, the temperature measurement result decreases by about 0.3°C, and when the temperature measurement site is 0.2 mm away from the exact center of the cigarette, the temperature measurement result decreases by nearly 1°C.

[0059] Preferably, in one embodiment, the temperature measuring end 31 extends into the central area of ​​the detection cavity 13, that is, the insertion depth of the temperature measuring end 31 into the detection cavity 13 in the radial direction is the central area of ​​the detection cavity 13. The distance between the temperature measuring end 31 and the central axis of the detection cavity 13 is less than 0.2 mm, that is, the temperature measuring end 31 deviates from the central axis of the central area of ​​the detection cavity 13 by less than 0.2 mm, so that the maximum temperature of the mainstream smoke can be measured more accurately.

[0060] More preferably, in one embodiment, the distance between the temperature measuring end 31 and the central axis of the detection cavity 13 is no more than 0.05 mm, that is, the temperature measuring end 31 deviates from the central axis of the central area of ​​the detection cavity 13 by less than or equal to 0.05 mm, thereby more accurately measuring the maximum temperature of the mainstream smoke.

[0061] Preferably, in one embodiment, along the axial direction of the mounting member 10, the sample mounting portion 11 and the suction mounting portion 12 are located at opposite ends of the mounting member 10, and the detection chamber 13 is arranged along the axial direction of the mounting member 10. With this structure, when installing the sample 200 and the suction device 300, it is only necessary to insert the sample 200 and the suction device 300 from opposite ends of the mounting member 10, and the installation is simpler and more convenient. In addition, during the measurement process, the smoke flows in a straight line along the axial direction, which can better simulate the actual suction scene, so that the smoke temperature of consumers when they normally smoke tobacco products can be measured more accurately.

[0062] Preferably, in one embodiment, a sample elastic fastener 1112 is provided in the sample installation cavity 111, and a suction device elastic fastener 1211 is provided in the suction installation cavity 121. The sample elastic fastener 1112 and the suction device elastic fastener 1211 are provided to make the sample 200 and the suction device 300 more convenient to install and remove. Specifically, the sample elastic fastener 1112 and the suction device elastic fastener 1211 can be a spring clip.

[0063] Preferably, in one embodiment, a mounting hole 16 is further provided on the side wall 14, the mounting hole 16 is communicated with the detection hole 15, the detection hole 15 is located inside the mounting hole 16, and the sealing member 20 is fixedly installed at the mounting hole 16. With this structure, the reliability of the connection and fixation between the sealing member 20 and the mounting member 10 can be increased. At the same time, when the sealing member 20 is installed on the mounting member 10, the positioning of the sealing member 20 is also simpler and more convenient.

[0064] Preferably, in one embodiment, the diameter of the mounting hole 16 is 0.5 mm. It is understandable that the diameter of the hole opened on the side wall 14 should not be too large, and setting the mounting hole 16 to 0.5 mm can not only facilitate the installation of the sealing member 20, but also make the sealing between the sealing member 20 and the mounting member 10 simpler, and can better ensure the sealing effect between the sealing member 20 and the mounting member 10, so as to better ensure the accuracy of the aerosol temperature measurement.

[0065] Specifically, the cross section of the sealing member 20 is a “T”-shaped structure, wherein the upper portion of the sealing member 20 has a larger diameter and the lower portion has a smaller diameter.

[0066] Preferably, in one embodiment, the seal 20 includes a seal mounting portion 21 installed in the mounting hole 16, and the outer diameter of the seal mounting portion 21 matches the aperture of the mounting hole 16. Wherein, the outer diameter of the seal mounting portion 21 matches the aperture of the mounting hole 16 means that the outer diameter of the seal mounting portion 21 is consistent with the aperture of the mounting hole 16, so that the seal 20 can be smoothly inserted into the mounting hole 16. Through this structure, when the seal 20 is installed on the mounting member 10, the sealing performance is good, there is no air leakage, and the installation and disassembly of the seal 20 is simpler and more convenient. Specifically, in one embodiment, the outer diameter of the seal mounting portion 21 is 0.5 mm. More preferably, in one embodiment, the sealing member 20 further includes an abutment portion 23 located outside the mounting hole 16, wherein the outer diameter of the abutment portion 23 is larger than the aperture of the mounting positioning hole 16, so that the abutment portion 23 cannot be inserted into the mounting positioning hole 16. The abutment portion 23 can abut against the outer peripheral surface of the mounting member 10, thereby playing a limiting role.

[0067] Preferably, in one embodiment, the length of the seal mounting portion 21 matches the depth of the mounting positioning hole 16. The length of the seal mounting portion 21 matches the depth of the mounting positioning hole 16, which means that the length of the seal mounting portion 21 is consistent with the depth of the mounting positioning hole 16, so that when the seal 20 is installed on the mounting member 10, the seal mounting portion 21 can completely fill and seal the mounting positioning hole 16, thereby better ensuring the sealing effect and preventing air leakage. At the same time, when the seal mounting portion 21 is fully inserted into the bottom of the mounting positioning hole 16, the abutment portion 23 also abuts against the outer peripheral surface of the mounting member 10, thereby limiting the mounting member 20 and making the positioning of the temperature sensor 30 simpler and more accurate.

[0068] Preferably, in one embodiment, the length of the seal mounting portion 21 is between 3.5-4 mm, and the outer diameter of the seal mounting portion 21 is 0.5 mm. Correspondingly, the depth of the mounting positioning hole 16 is between 3.5-4 mm, and the aperture of the mounting positioning hole 16 is 0.5 mm. It can be understood that the aperture of the hole opened on the side wall 14 should not be too large, and setting the mounting positioning hole 16 to 0.5 mm can not only facilitate the installation of the seal 20, but also make the sealing between the seal 20 and the mounting member 10 simpler, and can better ensure the sealing effect between the seal 20 and the mounting member 10, so as to better ensure the accuracy of the aerosol temperature measurement. Setting the length of the seal mounting portion 21 between 3.5-4 mm can make installation and disassembly simpler, while ensuring the sealing effect. The length of the abutting portion 23 is between 1.5-2 mm, and the outer diameter of the abutting portion 23 is between 2-3 mm. Through this structure, the abutting portion 23 can better realize the limiting function, and it is also more convenient to apply force during the installation and disassembly of the seal 20.

[0069] Specifically, in one embodiment, the length of the sealing member installation portion 21 is 3.5 mm, the length of the abutting portion 23 is 1.5 mm, and the outer diameter of the abutting portion 23 is 2 mm.

[0070] Specifically, in one embodiment, the length of the sealing member installation portion 21 is 4 mm, the length of the abutting portion 23 is 2 mm, and the outer diameter of the abutting portion 23 is 3 mm.

[0071] Specifically, in one embodiment, the sealing member installation portion 21 is cylindrical in shape as a whole, and the abutting portion 23 is disc-shaped in shape as a whole.

[0072] Preferably, in one embodiment, the seal 20 is a silicone seal or a rubber seal, that is, the seal 20 is made of silicone or rubber, so as to better ensure the sealing performance.

[0073] Preferably, in one embodiment, a sealing member center hole 22 is opened at the center of the sealing member 20, and the temperature sensor 30 is passed through the sealing member center hole 22. The temperature sensor 30 is a thermocouple, and the thermocouple wire diameter of the temperature sensor 30 matches the aperture of the sealing member center hole 22. The thermocouple wire diameter of the temperature sensor 30 matches the aperture of the sealing member center hole 22, which means that the thermocouple wire diameter of the temperature sensor 30 is consistent with the aperture of the sealing member center hole 22, so that the temperature sensor 30 can be smoothly inserted into the sealing member center hole 22. At the same time, through this structure, the sealing performance can be better guaranteed.

[0074] Preferably, in one embodiment, the diameter of the wire of the temperature sensor 30 is 0.254 mm. Specifically, in one embodiment, the diameter of the central hole 22 of the sealing member is 0.254 mm.

[0075] Preferably, in one embodiment, the sealing member center hole 22 is aligned with the detection hole 15. The alignment of the sealing member center hole 22 with the detection hole 15 means that the central axis of the sealing member center hole 22 and the central axis of the detection hole 15 are located on the same straight line, so that when the sealing member 20 is installed on the mounting member 10, the temperature sensor 30 can be directly inserted into the detection hole 15. With this structure, the temperature sensor 30 can be positioned more accurately.

[0076] Specifically, in one embodiment, the temperature sensor 30 is a K-type armored thermocouple or a T-type armored thermocouple.

[0077] In one embodiment, the temperature sensor 30 is inserted from the center hole 22 of the seal to form a combination with the seal 20, and then the combination is inserted into the mounting part 10 from the mounting hole 16, and the temperature sensor 30 is inserted into the central area of ​​the detection cavity 13 through the detection hole 15, and the temperature measuring end 31 of the temperature sensor 30 deviates from the central axis of the detection cavity 13 by no more than 0.05mm. After the position of the temperature measuring end 31 is adjusted, the temperature sensor 30, the seal 20, and the mounting part 10 are fixed to each other to form an integrated structure, which cannot be disassembled from each other, so as to realize the accurate positioning of the temperature sensor 30 in the axial and radial directions. During measurement, the temperature sensor 30 does not contact the end face of the filter outlet, and can accurately measure the maximum temperature of the mainstream smoke.

[0078] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the protection scope of the present invention.
