For example, the temperature sensing element can be affixed using glue or welded directly to the surface of the object being measured. Also as disclosed in prior art 1(CN204495478U), the fixing device for a thermocouple includes a fixing portion and a heat insulating layer, the fixing portion is provided with a slot clamped on a component to be tested, the heat insulating layer is disposed in the slot to separate the fixing portion from the component to be tested, and the temperature measuring element is attached to the surface of the component to be tested through the wire passing through holes on the fixing portion and the heat insulating layer. As disclosed in prior art 2(CN203405281U), the fixing device for a thermocouple includes a heat insulating portion, a barrel cavity adapted to a piece to be measured is formed in the heat insulating portion, and an installation groove for accommodating the temperature measuring element is further formed in an inner wall of the heat insulating portion. Through this fixed establishment, can make the temperature element of holding in the mounting groove and the piece that awaits measuring paste tightly, accomplish temperature measurement, avoid ambient temperature to temperature element temperature measurement's influence through thermal-insulated portion.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the present invention provides a temperature measuring system for a heating element 110, comprising:
a heating element fixing mechanism 200 for fixing the heating element 110 such that the heating element 110 extends along a first direction (i.e. the direction of the central axis of the heating element 110, such as the X-X direction shown in fig. 1);
a temperature measuring element 400 for measuring the temperature of the heating element 110;
the temperature measuring element fixing mechanism comprises a bracket 310 and a pressing component 320, wherein the extending direction of the pressing component 320 is preferably perpendicular to the first direction. The compressing assembly 320 comprises a first end and a second end, the first end of the compressing assembly 320 is fixedly connected with the bracket 310, the second end of the compressing assembly 320 is provided with an insulating part 321, and the compressing assembly 320 compresses the temperature measuring element 400 on the surface of the heating element 110 through the insulating part 321.
Alternatively, the relative positions of the heating element fixing mechanism 200 and the temperature element fixing mechanism can be moved in this application to adjust the relative positions of the heating element 110 and the pressing member 320; alternatively, the relative positions of the heating element fixture 200 and the temperature sensing element fixture can be fixed, such as being co-fixed to a substrate, and the relative positions of the heating element 110 and the pressing assembly 320 can be adjusted by moving the position at which the heating element 110 is fixed to the heating element fixture 200.
By adopting the technical scheme, one end of the compressing assembly 320 is fixedly connected with the bracket 310, and the temperature measuring element 400 can be compressed on the surface of the heating element 110 by adjusting the relative positions of the compressing assembly 320 and the heating element 110 through the other end of the compressing assembly 320, so that a corresponding annular groove does not need to be arranged according to the shape of the heating element 110, and the universality is stronger; compared with the fixing mode of circumferential cladding in the prior art, only one end face of the pressing assembly 320 is required to be in surface contact with the heating element 110 in the application, and the pressing assembly is not required to be matched with the surface of the heating element 110, so that the end face of the pressing assembly 320 in contact with the heating element 110 can be set to be the minimum, the contact area is reduced, and the heat loss is further reduced.
Further, just before the compressing component 320 contacts with the temperature measuring element 400 and does not deform due to compression of the temperature measuring element 400, the surface of the compressing component 320 contacting with the temperature measuring element 400 is parallel to the axial direction of the heating element 110, so that when the compressing component 320 compresses the temperature measuring element 400 on the surface of the heating element 110, the temperature measuring element 400 is uniformly stressed, no stress concentration point exists, the temperature measuring element 400 can be effectively prevented from being bent, and the temperature measuring precision is ensured. The contact surface between the pressing assembly 320 and the heating element 110 is a line contact or even a point contact, which can minimize the contact area between the pressing assembly 320 and the heating element 110. More preferably, the contact surface of the compressing assembly 320 with the temperature measuring element 400 is a plane, and the contact area between the compressing assembly 320 and the heating element 110 is small for the non-planar region to be measured on the heating element 110.
In order to further ensure the stable contact between the temperature measuring element 400 and the heating element 110, according to another embodiment of the present invention, as shown in fig. 2, the thermal insulation portion 321 comprises a rigid thermal insulation portion 3212 and an elastic thermal insulation portion 3211 which are connected, the elastic thermal insulation portion 3211 directly contacts the temperature measuring element 400, and the rigid thermal insulation portion 3212 does not contact the temperature measuring element 400, and is used for connecting the pressure rod 322 and the elastic thermal insulation portion 3211. The elastic heat insulation part 3211 is in good contact with the surface of the temperature measuring element 400 through proper deformation, and the rigid heat insulation part 3212 can conduct pressure to the surface of the temperature measuring element 400 better, so that the temperature measuring element 400 is ensured to be in stable contact with the heating element 110.
In order to further reduce the amount of heat to be discharged, the rigid insulating portion 3212 may preferably have an elongated cylindrical configuration with a diameter of 5mm or less and an aspect ratio of 3:1 or more, more preferably 5:1 or more, and from the viewpoint of avoiding breakage of the rigid insulating portion 3212 and reducing costs, the rigid insulating portion 3212 preferably has a diameter of 1mm or more and an aspect ratio of 10:1 or less.
On the other hand, the thermal conductivity of the thermal insulation portion 321 can be controlled to be less than 0.2W/mK, for example, the elastic thermal insulation portion 3211 may adopt "NITTO XF100NPT 01", and the thermal conductivity is less than 0.1W/mK; the rigid heat insulation portion 3212 may be made of a high temperature resistant material with a low thermal conductivity coefficient, such as fire-proof wood soaked with a flame retardant, and the thermal conductivity coefficient is 0.14-0.18W/mK.
Further, the temperature measuring element is a contact type temperature measuring element, specifically, a thermocouple, a thermal resistor, a thermistor, or the like, and is preferably a thermocouple in view of both cost and temperature measurement accuracy.
According to another embodiment of the present invention, as shown in fig. 2 and 3, the compressing assembly 320 is a rod shape, which means that the compressing assembly 320 is an elongated member, and the cross section perpendicular to the axial direction thereof may be a circle, a triangle, a rectangle, or even an irregular polygon, and the cross section area at different positions in the axial direction thereof may be the same or different.
Because the compressing assembly 320 is rod-shaped, the heat insulation part 321 at one end of the rod-shaped contacts with the surface of the heating element 110, and the end surface of the rod-shaped is small, so that the contact area with the heating element 110 is small, and excessive heat of the heating element 110 cannot be conducted to other parts; the structure of the pressing component 320 does not need to be adjusted according to the structure of the heating element 110, so that the universality is higher; when the heating element 110 is pressed tightly, the heating element does not rotate, and the temperature measuring element 400 can be accurately positioned in a certain selected area; after the measurement of one selected area is finished, the position of the heating element fixing mechanism 200 or the position of the temperature measuring element fixing mechanism can be flexibly moved, and then the measurement of the other selected area can be carried out, so that the multi-point measurement can be carried out; the temperature measuring element 400 can be fixed on the surface of the heating element 110 without bending, and the measuring effect is more accurate.
Further, the pressing assembly 320 further includes an elastically and telescopically deformable pressing rod 322, one end of the pressing rod 322 is connected to the bracket 310, and the other end is connected to the heat insulating portion 321. In the measuring process, the relative positions of the heating element 110 and the compressing assembly 320 can be adjusted firstly, the heat insulation part 321 of the compressing assembly 320 is pressed on a certain region to be measured of the heating element 110, then the compression rod 322 is compressed, the compression rod 322 is contracted towards the direction far away from the heating element 110, the heating element 110 is separated from the heat insulation part 321, the temperature measuring element 400 is placed on the region to be measured at the moment, then the compression rod 322 is released, the compressing assembly 320 compresses the temperature measuring element 400 on the region to be measured of the heating element 110 through the heat insulation part 321, and the operation is convenient and rapid. And the pressure provided by the elastic deformation is of a suitable magnitude, so that the temperature measuring element 400 or the heating element 110 is not damaged by excessive pressure compared with a rigid pressing structure.
Specifically, the pressing rod 322 can be a spring telescopic rod, and includes an inner tube, an outer tube and a spring, the outer tube is sleeved on the inner tube, and two ends of the spring are respectively connected to the inner tube and the outer tube. The spring can be arranged in the inner tube or sleeved outside the outer tube as shown in fig. 3. The compression spring provides the compression stroke and the appropriate pressure of the extension direction of the pressing component 320, the pressure can be adjusted by adjusting the elasticity of the spring and springs with different specifications, and the pressure is transmitted through the rigid heat insulation part 3212, so that the elastic heat insulation part 3211, the measuring end of the temperature measuring element 400 and the measured heating element 110 are in full contact.
Further, the heating element 110 in the present application may be a heating element 110 for an aerosol-generating device, for example, a heating element for heating a non-burning smoking article, or a heating element for an electronic cigarette smoking article.
The heating element 110 and the aerosol generating device are different in structure. The heating element 110 includes a rod, a sheet, a ring, a cylinder, a wire, etc., according to a heating manner. The outer shape of the aerosol-generating device may be designed in various configurations in consideration of various factors.
In thermometering the heating element 110 of the aerosol-generating device, the portion of the smoking article used to store the aerosol-generating article is removed, leaving only the main body portion of the smoking article, and the heating element securing mechanism 200 actually secures the heating element 110 by securing the smoking article body 100 during the measurement. Different heating element fixing mechanisms 200 can be selected for different shapes and structures of the smoking set body 100, for example, a square smoking set body 100 as shown in fig. 4, the outer surface of which has two parallel planes, and the heating element fixing mechanisms can be directly fixed by using flat tongs; either a round smoking article body 100 as shown in figure 5 or some smoking article body 100 with an irregular shape may be held in place using a three-jaw chuck or a multi-jaw chuck having more than 3 jaws.
In accordance with another embodiment of the present invention, to facilitate simultaneous measurements at multiple points, multiple hold-down assemblies 320 may be provided to measure multiple areas of the surface of the heating element 110 simultaneously.
Since it is necessary to measure the temperature of a plurality of areas on the surface of the heating element 110, in order to facilitate the replacement of the temperature measurement areas, according to another embodiment of the present invention, the temperature measurement system further includes a first displacement mechanism 330, the first displacement mechanism 330 is connected to the heating element fixing mechanism 200, and the position of the heating element 110 can be flexibly moved by the first displacement mechanism 330, so as to facilitate the measurement of different areas on the surface of the heating element 110.
Further, as shown in fig. 3 and 6, the first displacement mechanism 330 includes a first bottom plate 331, a second bottom plate 332, and a third bottom plate 333 which are connected in sequence, and further includes a first metering screw 334 and a second metering screw 335. The first metering screw 334 and the second metering screw 335 are provided with scales, the first base plate 331 and the second base plate 332 are connected through a dovetail chute extending along a first direction, a convex part with a first threaded hole is fixedly arranged on the first base plate 331, the first threaded hole also extends along the first direction, the first metering screw 334 is arranged in the first thread in a penetrating way, one end of the first metering screw is fixedly connected with the second base plate 332, and the second base plate 332 can move back and forth along the first direction by rotating the first metering screw 334. Similarly, the second base plate 332 and the third base plate 333 are connected by a dovetail sliding slot extending along a second direction, a convex portion with a second threaded hole is fixedly arranged on the second base plate 332, the second threaded hole also extends along the second direction, a second metering screw 335 is arranged in the second threaded hole in a penetrating manner, one end of the second metering screw is fixedly connected with the third base plate 333, and the third base plate 333 can be moved back and forth along the second direction (the Y-Y direction shown in fig. 1) by rotating the second metering screw 335, wherein the second direction is perpendicular to the first direction.
Because the heating element 110 has a small volume, the surface of the heating element 110 is divided into a plurality of regions to be measured, and if the temperature measuring element 400 is placed on a selected region to be measured on the heating element 110, it may take a long time to adjust the relative positions of the heating element 110, the temperature measuring element 400, and the pressing member 320 by using a conventional displacement adjusting mechanism.
In the present application, when starting the measurement, the relative positions of the heating element fixing mechanism 200 and the temperature measuring element fixing mechanism may be moved first; or to move the position where the heating element 110 is fixed on the heating element fixing mechanism 200; the positions of the pressing assembly 320 and the temperature measuring element 400 are coarsely adjusted by the second displacement mechanism 340 or the third displacement mechanism 350, so that the pressing assembly 320 and the temperature measuring element 400 are adjusted to be close to the region to be measured. The position of the heating element 110 can then be moved slightly by rotating the first and second metering screws 334, 335, via the fine adjustment function of the first displacement mechanism 330, such that the clamping assembly 320 clamps the temperature sensing element 400 precisely over the selected area to be measured.
After the temperature measurement of the first selected area is completed, the relative positions of the heating element fixing mechanism 200 and the temperature measuring element fixing mechanism do not need to be adjusted, or the position of the heating element 110 fixed on the heating element fixing mechanism 200 is moved, or the positions of the pressing component 320 and the temperature measuring element 400 are roughly adjusted through the second displacement mechanism 340 or the third displacement mechanism 350, the position of the heating element 110 can be moved only by lifting the pressing component 320 and rotating the first metering screw 334 and the second metering screw 335, and when the heating element 110 is moved to the temperature measuring element 400 located in the second selected area to be measured, the pressing component 320 is released, and the temperature measuring element 400 can be pressed on the second selected area to be measured through the pressing component 320. Through the scale on the metering screw, the heating element 110 can be moved in a micro-scale and accurate manner, and can be conveniently positioned to a plurality of areas to be measured.

Furthermore, the extending direction of the pressing assembly 320 is perpendicular to the first direction and the second direction, so as to avoid the need to further adjust the relative positions of the pressing assembly 320 and the heating element 110 due to the change of the telescopic state of the pressing assembly 320 caused by the movement of the heating element 100 towards the extending direction of the pressing assembly 320 when moving along the first direction or the second direction, such as over-compressing the pressing assembly 320 or directly exceeding the length range of the pressing assembly 320.
According to another embodiment of the present invention, the thermometric system further comprises a second displacement mechanism 340, the pressing assembly 320 is connected to the support 310 via the second displacement mechanism 340, and the position of the pressing assembly 320 can be moved by the second displacement mechanism 340, so as to facilitate the measurement of different areas on the surface of the heating element 110.
