The TCR detection apparatus 100 includes an infrared thermometry mechanism 20, a light guide mechanism 30, and a TCR detection device (not shown in fig. 1 and 2). The object to be measured is detachably carried on the TCR detection apparatus 100, and the infrared temperature measuring mechanism 20 is disposed at a distance from the object to be measured. At least part of the light guiding mechanism 30 is used for being adjacent to the heating element 201, the light guiding mechanism 30 can guide infrared light emitted by the heating element 201 to the infrared temperature measuring mechanism 20, and the infrared temperature measuring mechanism 20 is used for detecting the temperature of the heating element 201 according to the infrared light incident on the infrared temperature measuring mechanism 20. Optionally, the TCR detection apparatus 100 further includes a carrying mechanism 10, where the carrying mechanism 10 is used to carry the object to be detected.
In some embodiments, when detecting the TCR of the object under test, applying electrical energy to the heat-generating body 201, causing the heat-generating body 201 to generate heat; the TCR detection device controls the heating body 201 and at least part of the light guiding mechanism 30 to move relatively, so that at least part of the light guiding mechanism 30 is adjacent to the heating body 201, and infrared light generated by heating of the heating body 201 is guided to the infrared temperature measuring mechanism 20 through the light guiding mechanism 30; the TCR detection device controls the infrared temperature measuring mechanism 20 to acquire temperature information of the heating element 201 according to infrared light incident on the infrared temperature measuring mechanism 20, and acquires resistance information of the heating element 201; the target TCR of the heating element 201 is determined based on the temperature information and the resistance information of the heating element 201.

In some embodiments, the infrared thermometry mechanism 20 obtains temperature information of the heater based on energy of infrared light incident to the infrared thermometry mechanism 20. The TCR detection device 100 does not need to contact with the detected object or the heating element 201 when detecting the TCR, so that the problem that the detected object or the heating element 201 is easy to wear due to contact with the TCR detection device 100 is avoided, the temperature of the detected object or the heating element 201 is easy to influence due to contact of the detected object or the heating element 201 with the TCR detection device 100 is avoided, the heat loss is avoided, and the temperature measurement accuracy of the TCR detection device 100 for TCR detection of the heating element 201 or the detected object is greatly improved, so that the target TCR of the heating element 201 can be accurately determined according to accurate temperature information and resistance information of the heating element 201, and the whole TCR detection process does not need to be manually participated, so that the TCR detection efficiency and accuracy of the heating element 201 are greatly improved.
It will be understood that at least a portion of the light guiding mechanism 30 (such as the light guiding member 31 in fig. 5) is adjacent to the heat generating body 201 means that at least a portion of the light guiding mechanism 30 is not in contact with the heat generating body 201, and at least a portion of the light guiding mechanism 30 is kept at a predetermined distance from an outer wall or a hollow inner wall of the heat generating body 201, or the like.

In some embodiments, at least a portion of light guiding mechanism 30 is movable relative to heat generating body 201. In this way, the TCR detection apparatus 100 can measure TCRs of different regions to be detected of the heating element 201 according to actual demands. The relative position between at least part of the light guiding mechanism 30 and the heating element 201 can be adjusted when detecting the TCR, so that at least part of the light guiding mechanism 30 is located at a target guiding position corresponding to a target region of the heating element 201, so that the light guiding mechanism 30 can guide the infrared light emitted by the target region to the infrared temperature measuring mechanism 20, and the infrared temperature measuring mechanism 20 can accurately measure the temperature of the target region according to the infrared light incident to the infrared temperature measuring mechanism 20, and thus the TCR of the target region can be accurately calculated according to the measured temperature and the resistance value of the target region.
In some embodiments, when measuring the TCR of the object under test, the TCR detection apparatus 100 or the aerosol-generating device 200 applies electrical energy to the heater 201 from its own power source, causing the heater 201 to heat; the TCR detection device controls the heating body 201 and at least part of the light guiding mechanism 30 to move relatively, so that at least part of the light guiding mechanism 30 is adjacent to each of at least two detected areas on the heating body 201 in turn; the TCR detection device sequentially acquires the resistance information of each detected area and controls the infrared temperature measuring mechanism 20 to sequentially acquire the temperature information of each detected area according to the infrared light incident to the infrared temperature measuring mechanism 20; and determining the target TCR of the heating element according to the resistance information and the temperature information of each measured area. By measuring the resistance information and the temperature information of at least two measured regions on the heating element 201, it is possible to facilitate the subsequent accurate determination of TCR consistency at different positions of the heating element 201 by the resistance information and the temperature information of at least two measured regions.
Referring to fig. 3, in some embodiments, at least a portion of the light guiding mechanism 30 and the heat generating body 201 can move relative to each other in the axial direction of the heat generating body 201. In this way, the TCR detection apparatus 100 can perform TCR detection on a plurality of different portions in the axial direction of the heating element 201. Illustratively, the heat-generating body 201 includes N heat-generating segments, which are disposed at intervals along the axial direction of the heat-generating body 201, and the TCR detection apparatus 100 can accurately measure the TCR of each or a certain heat-generating segment, N being an integer greater than or equal to 2.
Referring to fig. 3 and 4, in some embodiments, the aerosol-generating device 200 comprises an aerosol-output end 202 and an aerosol-generating body 203, the aerosol-output end 202 being detachably or non-detachably connected to the aerosol-generating body 203. The aerosol output 202 comprises a port for the aerosol generating device to output aerosol for inhalation by a user, for example, the aerosol output 202 may be a filter tip. The aerosol-generating body 203 comprises a heating body 201 and a smoke tube 204, the heating body 201 comprises N heating sections surrounding the inner wall and/or the outer wall of the smoke tube 204, and each heating section is arranged on the inner wall and/or the outer wall of the smoke tube 204 at intervals. The smoke tube 204 is used for accommodating a cigarette 300, and the cigarette 300 can be a traditional cigarette or a special cigarette cartridge. In other embodiments, the aerosol-generating body 203 comprises a heat-generating body 201, excluding the smoke tube 204, and the heat-generating body 201 may house the cigarette 300.

The (i+1) th heat generating segment 201 (i+1) is farther from the aerosol output end 202 than the i-th heat generating segment 201 i. Since at least part of the light guiding mechanism 30 and the heating element 201 can relatively move in the axial direction of the heating element 201, the relative position between at least part of the light guiding mechanism 30 and the heating element 201 can be adjusted to the target guiding position in the axial direction of the heating element 201, the target guiding position corresponds to the target heating section of the heating element 201, so that the light guiding mechanism 30 can guide the infrared light emitted by the target heating section to the infrared temperature measuring mechanism 20, and the infrared temperature measuring mechanism 20 can accurately measure the temperature of the target heating section according to the infrared light incident to the infrared temperature measuring mechanism 20, and thus the TCR of the target heating section can be accurately calculated according to the measured temperature and the resistance value of the target heating section.
Referring to fig. 4, the aerosol-output end 202 is illustratively detachably connected to the aerosol-generating body 203.

In other embodiments, when the TCR detection apparatus 100 detects the TCR of the heating element 201, the aerosol output end 202 may be carried on the carrying mechanism 10 together with the aerosol-generating body 203, where the aerosol output end 202 is not detached from the aerosol-generating body 203, and the aerosol output end 202 does not affect the optical path between the heating element 201 and the light guiding mechanism 30, so that the light guiding mechanism 30 can guide the infrared light emitted by the heating element 201 to the infrared temperature measuring mechanism 20.

Referring to fig. 8 and 9, in some embodiments, the light guiding element 31 is mounted to the position adjustment assembly 32 by a link 33, and the light guiding element 31 is located at one end of the link 33. In this way, the light guiding element 31 and the position adjusting component 32 can be kept at a certain distance, the material selection of the position adjusting component 32, which is influenced by the heat of the heating element 201 adjacent to the light guiding element 31, is reduced, the connecting rod 33 is only required to be prepared by adopting a high-temperature resistant material such as ceramic, the position adjusting component 32 is prepared by adopting a common material without the high-temperature material, the material cost is reduced, and the position adjusting component 32 and other components (such as the bearing mechanism 10 or the heating element 201) are prevented from interfering in the process of driving the light guiding element 31 to move relative to the heating element 201.

In some embodiments, the infrared thermometry mechanism 20 includes a calibration light source (not shown) that emits visible light such that the visible light is directed through the light guide mechanism 30 to calibrate the target zone of the heater 201. Since the infrared light emitted by the heat generating body 201 is invisible light, before the TCR is detected, it is necessary to emit visible light (such as laser light) to the light guiding element 31 by the calibration light source, and adjust the positions of the connecting rod 33 in the X-axis direction, the Y-axis direction, and the Z-axis direction by the position adjusting component 32 or the second driving piece, so that the visible light emitted by the calibration light source is emitted to the central position of the light guiding element 31, and the visible light incident to the light guiding element 31 is vertically incident to a point of the target area of the heat generating body 201 after being guided by the light guiding element 31, so that the infrared light emitted by the point of the target area of the heat generating body 201 is guided to the infrared temperature measuring mechanism 20 by the light guiding element 31 as much as possible, thereby providing a guarantee for improving the accuracy of the TCR detection.

In some embodiments, the condensing element comprises a lens or a diffractive optical element, or the like.

In some embodiments, as shown in fig. 8 and 9, the light guiding element 31 is mounted on the position adjusting assembly 32 through a connecting rod 33, and the tcr detecting device adjusting assembly 32 operates to drive the light guiding element 31 to move relative to the heating element 201 may be as follows: the TCR detection apparatus adjusting assembly 32 operates to drive the link 33 to move, thereby driving the light guiding member 31 connected to the link 33 to move relative to the heating element 201.

In some embodiments, the manner of acquiring the resistance information of the heating element and controlling the infrared temperature measuring mechanism to acquire the temperature information of the heating element according to the infrared light incident on the infrared temperature measuring mechanism may be: under the condition that at least part of the light guiding mechanism is determined to be close to the heating element and electric energy is applied to the heating element according to the first power, controlling the resistance sampling circuit to collect the resistance value of the heating element at a preset sampling frequency within a preset target duration, so as to obtain the resistance information of the heating element; and simultaneously controlling the infrared temperature measuring mechanism to acquire the temperature value of the heating element according to the infrared light incident to the infrared temperature measuring mechanism at a preset sampling frequency, thereby acquiring the temperature information of the heating element. Wherein, when electric energy is applied to the heating element according to the first power, the heating element is slowly heated. Of course, in other embodiments, the temperature value of the heating element and the sampling time of the resistance value may be recorded at the same time. According to the embodiment, the first power is used for applying electric energy to the heating element, so that the heating element is heated slowly, the temperature change and the resistance change of the heating element can be guaranteed to be in gentle states, the temperature value and the resistance value of the heating element can be accurately detected at the moment, and the TCR of the heating element can be accurately calculated according to the accurate temperature of the heating element and the resistance value of the heating element.

It will be appreciated that the resistance sampling circuit may be a resistance sampling circuit in the aerosol generating device 200, or may be a resistance sampling circuit in the TCR detection apparatus 100, and the preset target duration and the preset sampling frequency may be set based on actual situations, which is not specifically limited in the embodiment of the present invention. For example, the preset target duration is 10 seconds, the preset sampling frequency is 500 ms/time, that is, under the condition that at least part of the light guiding mechanism is close to the heating element and the heating element heats, the resistance sampling circuit is controlled to collect the resistance value of the heating element once every 500ms within 10 seconds, meanwhile, the infrared temperature measuring mechanism is controlled to collect the temperature value of the heating element once every 500ms according to the infrared light incident to the infrared temperature measuring mechanism, and the sampling time for collecting the temperature value and the resistance value of the heating element is recorded, so that 20 resistance values, 20 temperature values and 20 sampling time of the heating element can be obtained.

Wherein, when electric energy is applied to the heating element according to the second power, the heating element is heated up rapidly. Of course, in other embodiments, the temperature value of the heating element and the sampling time of the resistance value may be recorded at the same time. Because the heat-generating body is at earlier stage in-process that generates heat, the temperature of heat-generating body rises very fast, and the resistance change of heat-generating body also very fast, is difficult to accurately detect the temperature value and the resistance of heat-generating body, and this embodiment is through stopping applying the electric energy for the heat-generating body after applying the electric energy for the heat-generating body for a period of time, and temperature change and the resistance change of heat-generating body all are in mild state, can accurately detect the temperature value and the resistance of heat-generating body this moment, can accurately calculate the TCR that obtains the heat-generating body according to the accurate temperature of heat-generating body and the resistance of heat-generating body like this. Illustratively, the second power is greater than the first power to achieve a rapid heating up of the heat-generating body.
It is to be understood that the first preset duration, the preset target duration, and the preset sampling frequency may be set based on actual situations, which is not specifically limited in the embodiment of the present invention. For example, the first preset duration is 30 seconds, the preset target duration is 10 seconds, and the preset sampling frequency is 500 ms/time, namely, after at least part of the light guiding mechanism is close to the heating element and the heating element heats for 30 seconds, the application of electric energy to the heating element is stopped, the resistance sampling circuit is controlled to collect the resistance value of the heating element once every 500ms within 10 seconds after the application of the electric energy to the heating element is stopped, meanwhile, the infrared temperature measuring mechanism is controlled to collect the temperature value of the heating element once every 500ms according to the infrared light incident to the infrared temperature measuring mechanism, and the sampling time for collecting the temperature value and the resistance value of the heating element is recorded, so that 20 resistance values, 20 temperature values and 20 sampling times of the heating element can be obtained.

For another example, according to the resistance value R 1 Resistance value R 2 Temperature value T 1 And a temperature value T 2 Can be calculated to obtainAccording to the resistance value R 2 Resistance value R 3 Temperature value T 2 And a temperature value T 3 Can calculate +.>According to the resistance value R 3 Resistance value R 4 Temperature value T 3 And a temperature value T 4 Can calculate +.>According to the resistance value R 1 Resistance value R 3 Temperature value T 1 And a temperature value T 3 Can calculate +.>According to the resistance value R 2 Resistance value R 4 Temperature value T 2 And a temperature value T 4 Can calculate +.>According to the resistance value R 1 Resistance value R 4 Temperature value T 1 And a temperature value T 4 Can calculate +.>Calculation of TCR 1 、TCR 2 、TCR 3 、TCR 4 、TCR 5 And TCR (thyristor controlled reactor) 6 Thus, the average value (TCR) 1 +TCR 2 +TCR 3 +TCR 4 +TCR 5 +TCR 6 ) And/6, determining the target TCR of the heating element.

The method comprises the steps of applying electric energy to N heating sections simultaneously, and stopping applying electric energy to N heating sections after a first preset duration; after the duration of stopping applying the electric energy to the N heating sections reaches the second preset duration, sequentially applying the electric energy to each heating section in the N-1 heating sections according to the sequence from the N-1 heating section to the 1 st heating section or the sequence from the 2 nd heating section to the N heating section, and stopping applying the electric energy to the heating sections after the third preset duration is continued. Because the heating section is in the in-process that earlier stage was generated heat, the temperature of heating section rises very fast, and the resistance change of heating section is also very fast, be difficult to accurate detection heating section's temperature value and resistance, and this embodiment stops to N heating section through for N heating section after applying electric energy simultaneously for a period of time, and stop to apply electric energy for heating section for each heating section in N-1 heating section in proper order and last for a period of time later, can guarantee like this that the temperature change and the resistance change of each heating section all are in mild state, and through the effect of still preheating for N heating section simultaneous application electric energy, can avoid leading to the too fast problem of heating section cooling to appear after stopping to apply electric energy for heating section, be convenient for follow-up accurate detection heating section's temperature value and resistance.
It may be appreciated that the first preset duration, the second preset duration, and the third preset duration may be the same or different, and the first preset duration, the second preset duration, and the third preset duration may be set based on actual situations, which is not specifically limited in the embodiment of the present invention. For example, the first preset duration is 30 seconds, the second preset duration is 10 seconds, and the third preset duration is 20 seconds. For another example, the first preset duration is 30 seconds, the second preset duration is 15 seconds, and the third preset duration is 30 seconds.
In some embodiments, in the process of sequentially applying electric energy to each of the N-1 th heat generating sections for a third preset period of time and stopping applying electric energy to the heat generating sections, according to the sequence from the 2 nd heat generating section to the nth heat generating section, the resistance information and the temperature information of the 1 st heat generating section are detected in a second preset period of time after stopping applying electric energy to the N th heat generating sections, and the resistance information and the temperature information of the i th heat generating section are detected in a second preset period of time after stopping applying electric energy to the i th heat generating section, where i is greater than or equal to 2 and less than or equal to N. Therefore, the resistance information and the temperature information of each heating section can be acquired in the cooling process of each heating section in sequence, and the preheating effect of the next heating section can be achieved when the electric energy is applied to the previous heating section, so that the next heating section is not cooled too fast due to supercooling.

Therefore, the resistance information and the temperature information of each heating section can be acquired in the cooling process of each heating section in sequence, and the preheating effect of the next heating section can be achieved when the electric energy is applied to the previous heating section, so that the next heating section is not cooled too fast due to supercooling.

After the duration of stopping applying the electric energy to the 4 heating sections reaches 10 seconds, applying the electric energy to the 3 rd heating section and stopping applying the electric energy to the 3 rd heating section after lasting 20 seconds; and collecting resistance information and temperature information of the 3 rd heating section within 10 seconds after the power supply to the 3 rd heating section is stopped. Then, after the duration of stopping applying the electric energy to the 3 rd heating section reaches 10 seconds, applying the electric energy to the 2 nd heating section and after the duration of 20 seconds, stopping applying the electric energy to the 2 nd heating section; and collecting resistance information and temperature information of the 2 nd heating section within 10 seconds after the power supply to the 2 nd heating section is stopped. And finally, after the duration of stopping applying the electric energy to the 2 nd heating section reaches 10 seconds, applying the electric energy to the 1 st heating section for 20 seconds, stopping applying the electric energy to the 1 st heating section, and collecting the resistance information and the temperature information of the 1 st heating section within 10 seconds after stopping applying the electric energy to the 1 st heating section.

The electric energy can be applied to each heating section of the N heating sections according to the first power, so that each heating section of the N heating sections slowly heats in turn. It is to be understood that the fourth preset duration may be set based on actual situations, which is not specifically limited in the embodiment of the present invention. For example, the fourth preset time period is 35 seconds. According to the embodiment, the first power is used for applying electric energy to the heating element, so that the heating element is heated slowly, the temperature change and the resistance change of the heating element can be guaranteed to be in gentle states, and the temperature value and the resistance value of the heating element can be accurately detected later.
