[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0034] Embodiment 1:

[0035] As countries gradually tighten their control over cigarettes and people pay more and more attention to health, a type of heat-not-burn e-cigarette has become increasingly popular in recent years. It is a product that mainly converts nicotine and other substances in tobacco into vapor through atomization and other means, and then allows users to inhale it.

[0036] Dry-burning smoking utensils or low-temperature heating without burning smoking utensils are temperature-controlled baking smoking utensils. This type of smoking utensils has the function of low-temperature baking and smoking. It does not require very high temperatures and will reduce a large number of unknown substances and harmful substances. The temperature requirements of low-temperature baking and heating without burning smoking utensils are strict, so there must be high requirements for the accuracy of the temperature. If the temperature is too high, there will be harmful substances that should not appear. If the temperature is too low, it will cause small smoke or no smoke.

[0037] The heating element of this type of smoking device is small in size, and contact temperature measurement methods such as thermocouples and thermal resistors will have a great impact on the accuracy and efficiency of temperature measurement. At present, thermal imagers and other equipment are widely used in production to measure the temperature of the heating element through non-contact temperature measurement. The thermal imager system usually consists of a thermal imager lens and a host computer. The thermal imager lens detects the temperature data of the object being measured and transmits the data to the host computer. The temperature data is then processed by the host computer to obtain the real data of the object being measured.

[0038] At present, each manufacturer usually sets up a single thermal imager to test the temperature of the heating element. It is understandable that due to the deviation factors such as the heating circuit, manufacturing process, and installation position of the heating element, there are temperature differences between individual heating elements in different positions and between individuals. Testing in one direction with a single thermal imager cannot well reflect the actual temperature of the heating element. In mass product testing, it is easy to cause the risk of excessive temperature test errors.

[0039] like Figure 1 As shown, currently each manufacturer usually sets a single thermal imager to test the temperature of the heating element. Since the heating element in the heating device does not heat evenly, a single thermal imager corresponding to a test direction cannot well feedback the actual temperature of the heating element in the heating device.

[0040] In view of this, the present embodiment provides a temperature measurement system for a heating element 20 of a heating smoking device, the temperature measurement system comprising: a clamping and positioning device 10, a temperature measuring module and a host computer 40, the clamping and positioning device 10 is used to clamp and position the heating element 20, the temperature measuring module is used to measure the heating data of the heating element 20, the host computer 40 is communicatively connected with the temperature measuring module, and is used to receive the heating data fed back by the temperature measuring module, the temperature measuring device 30 in the temperature measuring module comprises a first temperature measuring device and a second temperature measuring device, the first temperature measuring device and the second temperature measuring device are distributed at different measuring positions, and are used to measure the heating data of different positions of the heating element 20.

[0041] Optionally, the host computer 40 may include a display unit, a communication unit, a parameter preset unit and an alarm unit.

[0042] The display unit can be used to display a test screen, an operation interface, etc. The test screen can display the heating data of the object under test (e.g., the heating element 20 of the heating device), and the heating data can include information such as the temperature and heat distribution of the object under test. The operation interface can set the parameters such as the emissivity, data frequency, and temperature measurement mode of the temperature measuring device 30 according to the needs of those skilled in the art.

[0043] The communication unit can be used to establish a communication connection between the host computer 40 and the temperature measurement module. It can be understood that the communication connection can be established by wired or wireless means. For example, the wired communication connection can include serial communication, Ethernet communication, USB communication, etc., and the wireless communication connection can include Wi-Fi, Bluetooth, Zigbee, LoRa, etc.

[0044] It should be noted that those skilled in the art can select a suitable connection method according to the specific application scenario, and this application is not limited thereto.

[0045] It can be understood that in this embodiment, at least two temperature measuring devices 30 are arranged at different measurement positions to measure the heating data of the heating element 20 at different viewing angles, so as to improve the accuracy of measuring the real temperature of the heating element 20 and reduce the influence of deviation factors such as the heating position and heating route of the heating element 20.

[0046] In one embodiment, the first temperature measuring device and the second temperature measuring device are placed relatively on both sides of the axis of the heating element 20 so that the first line of sight and the second line of sight are parallel or overlapped with each other, so as to respectively measure the heating data of the two opposite sides of the heating element 20.

[0047] like Figure 2As shown, two temperature measuring devices 30 can be arranged at different measuring positions respectively. For example, two temperature measuring devices are placed on both sides of the smoking device respectively. The measuring lenses of the temperature measuring devices 30 are aimed at both sides of the heating element 20 of the smoking device to measure the heating data of different parts of the heating element 20.

[0048] In one embodiment, the first line of sight and the second line of sight form an angle of 90 degrees and are respectively perpendicular to the axis of the heating element 20 , and are used to measure the heating data of two adjacent side surfaces of the heating element 20 .

[0049] like Figure 3 As shown, in one embodiment provided in the present application, two temperature measuring devices 30 can be placed at an angle of 90 degrees with the smoking device as the axis.

[0050] In one embodiment, the first temperature measuring device is placed near the top of the heating element 20 and the first line of sight is directed toward the top of the heating element 20, so as to measure the heating data of the top surface of the heating element 20; the second temperature measuring device is placed near the side of the heating element 20 and the second line of sight is directed toward the side of the heating element 20, so as to measure the heating data of the side of the heating element 20.

[0051] like Figure 4 As shown, in an embodiment provided in the present application, one of the two temperature measuring devices 30 can be placed on the side of the smoking device, and the other temperature measuring device 30 can be placed on the top of the smoking device to measure the front temperature of the heating element 20.

[0052] In one embodiment, the temperature measurement module may further include a third temperature measurement device 30 .

[0053] like Figure 5 As shown, in an embodiment provided in the present application, three temperature measuring devices 30 can be set and placed on three sides of the smoking device respectively with the measuring angles aimed at different positions of the heating element 20 to jointly test the heating data of the three sides of the heating element 20 of the smoking device.

[0054] like Figure 6 As shown, in one embodiment provided in the present application, two temperature measuring devices 30 can be set and placed on the sides of the heating element 20 with different measuring angles to measure the heating data of different sides of the heating element 20 of the smoking device, and one temperature testing device is placed on the top of the smoking device to measure the heating data of the front side of the heating element 20 of the smoking device.

[0055] In one embodiment, the clamping and positioning device 10 and the first temperature measuring device and / or the second temperature measuring device are relatively movable.

[0056] like Figure 7As shown, in one embodiment provided in the present application, a mobile device 50 can be set at the bottom of the temperature measuring device 30, and the movement of the mobile device 50 can be controlled by remote control to adjust the measuring angle of the temperature measuring device 30, so as to facilitate the acquisition of heating data of different parts of the heating element 20 of the smoking device.

[0057] In one embodiment, the first temperature measuring device and the second temperature measuring device are kept in fixed positions, and the clamping and positioning device 10 can be moved or rotated to change the positional relationship between the heating element 20 and the first line of sight and / or the second line of sight.

[0058] like Figure 8 As shown, a moving device 50 can be provided at the bottom of the clamping and positioning device 10, and the movement of the moving device 50 can be controlled by remote control, thereby adjusting the temperature measuring device 30 to obtain heating data of different parts of the heating element 20 of the smoking device.

[0059] Optionally, the mobile device 50 may be integrally formed with the temperature measuring device 30 , that is, the temperature measuring device 30 itself has a mobile function.

[0060] It can be understood that the moving device 50 can also be integrally formed with the clamping and positioning device 10, that is, the clamping and positioning device 10 itself has a moving function.

[0061] In one embodiment, the first temperature measuring device and the second temperature measuring device are kept in fixed positions, and the clamping and positioning device 10 can be moved or rotated to change the angular relationship between the heating element 20 and the first line of sight and / or the second line of sight.

[0062] In one embodiment, the clamping and positioning device 10 maintains a fixed position, and the first temperature measuring device and the second temperature measuring device are movably arranged around the clamping and positioning device 10 .

[0063] like Fig. 9 As shown, the temperature measuring device 30 can be clamped by setting a free clamping device 60 such as a robotic arm, and the host computer 40 sends an operation instruction to the free clamping device 60, so that the free clamping device 60 moves the temperature measuring device 30 to the target position, so as to adjust the placement position of the temperature measuring device 30 and measure the heating data of different parts of the heating element 20.

[0064] like Fig.10As shown, the clamping and positioning device 10 can be clamped by setting a free clamping device 60 such as a robotic arm, and the upper computer 40 sends an operation instruction to the free clamping device 60, so that the free clamping device 60 moves the clamping and positioning device 10 to the target position to adjust the placement position of the heating element 20, thereby realizing the measurement of the heating data of different parts of the heating element 20.

[0065] In one embodiment, the first temperature measuring device and the second temperature measuring device are kept in fixed positions, and the clamping and positioning device 10 can rotate at multiple angles relative to the first temperature measuring device and the second temperature measuring device.

[0066] In one embodiment, the clamping and positioning device 10 maintains a fixed position, and the first temperature measuring device and the second temperature measuring device are movably arranged around the clamping and positioning device 10 .

[0067] Exemplarily, by setting a preset rotation angle for the free clamping device 60 , the heating data of the heating element 20 at various angles on the horizontal plane and the vertical plane can be obtained.

[0068] Furthermore, by setting the rotation time interval of the moving device 50 , it is possible to realize automatic and three-dimensional measurement of the heating data of the heating element 20 in all directions, thereby improving the test efficiency.

[0069] In one embodiment, the clamping and positioning device 10 maintains a fixed position, and the first temperature measuring device and the second temperature measuring device are movably arranged around the clamping and positioning device 10 .

[0070] Exemplarily, by setting a preset rotation angle for the mobile device 50 , the heating data of the heating element 20 in various directions on the horizontal plane can be obtained.

[0071] Furthermore, by setting the rotation time interval of the mobile device 50 , it is possible to automatically measure the heating data of the heating element 20 in various directions.

[0072] In one embodiment, the first temperature measuring device and / or the second temperature measuring device is an infrared thermal imager, and the heating element 20 is clamped and positioned by the clamping and positioning device 10 within the first line of sight and / or the second line of sight.

[0073] Since the heating element 20 of the smoking device is relatively small, the temperature detection of the heating element 20 by contact temperature measurement methods such as thermocouples and thermal resistors will have a great impact on the temperature measurement accuracy and efficiency. Therefore, non-contact temperature measurement methods such as infrared thermal imagers can be used to measure the heating data of the heating element 20.

[0074] The infrared thermal imager can realize multiple temperature measurement modes, which can specifically include point measurement mode, average temperature mode and maximum temperature mode. Among them, the point measurement mode can set the temperature of a certain point to be tested through the operation interface. The average temperature mode can set the average temperature of a certain area to be tested through the operation interface. The maximum temperature mode can set the temperature of the highest temperature position in a certain area to be tested through the operation interface of the host computer 40.

[0075] It can be understood that since the heating element 20 does not generate heat uniformly, there is also a temperature difference inside the heating element 20. The point measurement mode and the average temperature mode place high demands on the accuracy of the fixed position of the heating element 20, and the test results will be slightly deviated from the position. Therefore, the highest temperature mode can be used to test the heating element 20, set a temperature measurement area that exceeds the shape of the heating element 20, put the heating element 20 into the area, and the highest temperature measured is defaulted to the temperature of the heating element 20.

[0076] Based on the above inventive concept, the present application also provides a temperature calibration method for a heating element of a heating smoking device based on a temperature measurement system, which method may include the following steps:

[0077] S1. Place the heated smoking device at room temperature to cool for 15 minutes.

[0078] It can be understood that by placing the heating smoking device at room temperature to cool, it can be ensured that the heating element of the heating smoking device is at room temperature.

[0079] S2, start the heating smoking device to heat the heating element, and start the temperature measurement system to calibrate the temperature of the heating element in the heating state to determine whether the heating element has a fault.

[0080] S3. When it is determined that the heating element is not faulty, the temperature measurement system records the temperature of the heating element and the corresponding resistance value.

[0081] S4. The temperature measurement system stores the temperature of the heating element and the corresponding resistance value in the memory of the heating smoking device.

[0084] The temperature measurement module includes a first temperature measuring device and a second temperature measuring device, which are distributed at different measurement positions and are used to respectively measure different first-line heating data and second-line heating data of the heating element.
