Referring to fig. 1, a temperature detecting device 1 includes a thermocouple wire set 11 and a stretching assembly 12, wherein the thermocouple wire set 11 is connected with the stretching assembly 12. Wherein the double-headed arrow in fig. 1 indicates the direction of movement of the stretching assembly 12. The thermocouple wire is configured to be electrically connected with an external circuit device, thereby realizing temperature detection of the object to be detected. The stretching assembly 12 is configured to drive the thermocouple wire group 11 to move so that the detecting portion 113 of the thermocouple wire group 11 is close to the object to be measured, thereby improving the accuracy of temperature measurement. It will be appreciated that the test object may be a heating element adapted to the aerosol-generating device, the heating element may be a heated needle, a heated plate or a heated rod, etc.; of course, the object to be measured may be another object whose temperature needs to be detected.

In an embodiment, referring to fig. 2, the thermocouple wire group 11 includes a first thermocouple wire 111 and a second thermocouple wire 112, opposite ends of the first thermocouple wire 111 and the second thermocouple wire 112 are respectively a hot end and a cold end, and the hot ends of the first thermocouple wire 111 and the second thermocouple wire 112 are connected, so that the first thermocouple wire 111 and the second thermocouple wire 112 form a thermocouple, and an end portion where the first thermocouple wire 111 and the second thermocouple wire 112 are connected to each other forms a detecting portion 113 of the thermocouple, and the thermocouple may be a K-type thermocouple, a J-type thermocouple, or other type thermocouples. The detecting portion 113 is located outside the stretching assembly 12, the detecting portion 113 is used for being close to an object to be detected, and the cold end of the first thermocouple wire 111 and the cold end of the second thermocouple wire 112 are electrically connected with an external circuit device to form a circuit for completely detecting the temperature of the object to be detected. In some embodiments, the hot side of the first thermocouple wire 111 and the hot side of the second thermocouple wire 112 are welded using laser welding. The diameter of the first galvanic wire 111 is 0.1mm to 0.2mm and the diameter of the second galvanic wire 112 is 0.1mm to 0.2mm. Wherein the diameter of the probe portion 113 is 0.2mm to 0.3mm.

In an embodiment, the first thermocouple wire 111 and the second thermocouple wire 112 each include a thermocouple wire and an insulating layer coated on the surface of the thermocouple wire, where the insulating layer is used to protect the thermocouple wires in the first thermocouple wire 111 and the second thermocouple wire 112, and also is used to prevent the thermocouple wires in the first thermocouple wire 111 and the thermocouple wires in the second thermocouple wire 112 from being electrically connected to each other, and at the same time, it is possible to avoid the thermocouple wires in the first thermocouple wire 111 and the thermocouple wires in the second thermocouple wire 112 from directly contacting the stretching assembly 12. Wherein, the surfaces of the cold end and the hot end of the first thermocouple wire 111 and the second thermocouple wire 112 are not provided with insulating layers, i.e. the detecting part 113 is exposed outside the insulating layers. In some embodiments, the length of the cold and hot ends of the wire surfaces of the first and second wires 111, 112 without an insulating layer is 0.5mm to 3mm.

In the process of detecting the temperature of the object to be detected, the detecting part 113 is first sleeved on the periphery of the object to be detected, so that the first thermocouple wire 111 and the second thermocouple wire 112 are respectively arranged on two opposite sides of the object to be detected, and then the stretching assembly 12 can be used for dragging the first thermocouple wire 111 and the second thermocouple wire 112 to move, so that the detecting part 113 approaches to and abuts against the object to be detected, and at the moment, the object to be detected can be measured for measuring the temperature. Then, the first thermocouple wire 111 and the second thermocouple wire 112 are moved in the opposite direction, so that the contact between the detecting section 113 and the object to be measured is relaxed, and then the detecting section 113 is moved along the object to be measured until the detecting section 113 is disengaged from the object to be measured. It will be appreciated that in some embodiments, in order to prevent the first and second wires 111 and 112 from being pulled apart during tightening, the pulling force on the first and second wires 111 and 112 should be controlled to be 1N to 3N.

In an embodiment, the detecting portion 113 is used for contacting with the surface of the object to be detected, so the shape of the detecting portion 113 is limited by the surface shape of the object to be detected, and when the object to be detected is rod-shaped and has a circular arc-shaped side surface, as shown in fig. 2, the shape of the detecting portion 113 may be configured into a substantially arc shape, for example, a ". U. In other embodiments, the probe 113 may be configured in a general "U" shape or other shape.

In an embodiment, referring to fig. 5, an inner side surface of the detecting portion 113 has a contact area 1131, and the contact area 1131 is configured to enable the detecting portion 113 to contact with an outer surface of the object to be detected.

When a force is applied to the moving member 121 to move the moving member 121 relative to the static component 122, the moving member 121 drives the first and second wires 111 and 112 to move relative to the static component 122, so that the detecting portion 113 is far from the static component 122 or near to the static component 122. In the embodiment shown in fig. 1, when the moving member 121 moves upward relative to the stationary member 122 in the direction indicated by the double arrow, the detecting portion 113 of the thermocouple is folded toward the stationary member 122, so that the thermocouple wire between the detecting portion 113 and the moving member 121 is shortened, and the detecting portion 113 approaches and abuts the object to be measured; when the movable element 121 moves downward in the direction indicated by the double arrow with respect to the stationary element 122, the thermocouple wire between the probe portion 113 and the movable element 121 is relaxed by extension, and at this time, the probe portion 113 can be separated from the object to be measured.

In one embodiment, referring to fig. 3, the stretching assembly 12 further includes a locking member 123, the locking member 123 being disposed on the moving member 121 and/or the static member 122, the locking member 123 being configured to prevent movement of the moving member 121 relative to the static member 122 to prevent undesired relative movement of the moving member 121 and the static member 122, helping to keep the thermocouple wire between the probe 113 and the moving member 121 shortened or relaxed.

In some embodiments, referring to fig. 1 and 3, the static component 122 includes a first static member 1221. A part of the moving member 121 is connected to the first stationary member 1221, and the moving member 121 is capable of moving relative to the first stationary member 1221, and a part of the first thermocouple wire 111 and a part of the second thermocouple wire 112 are both fixed to the moving member 121 so that the first thermocouple wire 111 and the second thermocouple wire 112 move in synchronization with the moving member 121. Specifically, the first static member 1221 is a tubular static member, the moving member 121 includes a rod 1211 and an operating portion 1212, the rod 1211 is nested inside the first static member 1221 and is movable along an axial direction of the first static member 1221, the operating portion 1212 is connected to the rod 1211, a distance between at least a partial outer contour of the operating portion 1212 and a central axis of the first static member 1221 is greater than an inner diameter of the first static member 1221, and the operating portion 1212 is configured to receive a force to drive the rod 1211 to move inside the first static member 1221 along the axial direction of the first static member 1221. The rod 1211 is hollow or has a wiring groove on the side wall, the first thermocouple 111 and the second thermocouple 112 are disposed inside the first static member 1221 and inside the hollow or wiring groove of the rod 1211, and the detecting portion 113, the cold end of the first thermocouple 111, and the cold end of the second thermocouple 112 are all located outside the first static member 1221 and the moving member 121. It will be appreciated that in other embodiments, the first static member 1221 may have other shapes, such as a cross-section of the first static member 1221 having a C-shape, or a plurality of C-shaped tubes having different opening directions along the extending direction of the first static member 1221.

In the above embodiment, the length of the rod 1211 may be 5mm to 30mm, and the diameter of the rod 1211 may be 0.8mm to 2.8mm. The length of the first static member 1221 may be 20mm to 50mm, the diameter of the first static member 1221 may be 1mm to 3mm, and the diameter of the rod 1211 may be slightly smaller than the diameter of the first static member 1221, so that the rod 1211 may be inserted into the inside of the first static member 1221. As an example, the first stationary member 1221 is made of a high temperature resistant material, for example, a polyimide film having a thickness of 0.06mm to 0.08mm, a length of 70mm to 80mm, and a width of 40mm to 50mm is rolled into a tubular first stationary member 1221 having an outer diameter of 2.5mm to 2.8mm and an inner diameter of 2.4mm to 2.7mm for accommodating thermocouple wires while the first stationary member 1221 plays a supporting role at the time of testing.

Further, when the stretching assembly 12 includes an elastic member, the elastic member may be a spring, which is sleeved outside or inside the first static member 1221, and the spring is connected to the first static member 1221 and the moving member 121, respectively. When the acting force is applied to drive the moving member 121 to move, so that the detecting part 113 is far away from the first static member 1221, the spring is compressed to have elastic potential energy, and after the detecting part 113 is sleeved on the periphery of the object to be detected, the acting force on the moving member 121 is removed, and under the acting force of the spring, the moving member 121 moves reversely to drive the first thermocouple wire 111 and the second thermocouple wire 112 to move, so that the detecting part 113 is clung to the surface of the object to be detected.

Still further, referring to fig. 3, when the stretching assembly 12 further includes the locking member 123, the locking member 123 includes a first locking portion 1231 and a second locking portion 1232, the first locking portion 1231 is disposed on the moving member 121, and the second locking portion 1232 is disposed on the first static member 1221. When the detecting part 113 needs to be sleeved on the outer peripheral surface of the object to be detected, the moving part 121 is driven to move by applying an acting force so as to enable the first locking part 1231 to be connected with the second locking part 1232, the moving part 121 is in a locked state, namely, the moving part 121 is fixed relative to the first static part 1221, and the moving part 121 is locked so as to facilitate the sleeving operation of the detecting part 113. When the detection portion 113 is sleeved, the first locking portion 1231 and the second locking portion 1232 are separated by applying an acting force, the moving member 121 is in an unlocked state, and under the acting force of the spring, the moving member 121 moves reversely to drive the first thermocouple wire 111 and the second thermocouple wire 112 to move, and the detection portion 113 is attached to the surface of the object to be detected.

Further, the locking member 123 further includes an unlocking member 1233, the unlocking member 1233 is disposed on the first static member 1221, one end of the unlocking member 1233 is exposed to the outside, and the other end of the unlocking member 1233 abuts against the moving member 121. The unlocking member 1233 is configured to receive an external force such that the first locking part 1231 and the second locking part 1232 are separated, thereby unlocking the moving member 121 to the first stationary member 1221.

In other embodiments, referring to fig. 4, the static component 122 includes a first static member 1221, and the moving member 121 is partially connected to the first static member 1221, where the moving member 121 is configured to rotate relative to the first static member 1221. The thermocouple wire group 11 is connected to the moving member 121, and the thermocouple wire group 11 is configured to be wound around the moving member 121 when the moving member 121 rotates in the first direction with respect to the first stationary member 1221. For example, the part of the moving member 121 is tubular, the tubular moving member 121 is sleeved on the periphery of the first static member 1221, and the moving member 121 can rotate relative to the first static member 1221.

When the moving member 121 rotates along the first direction, the moving member 121 winds the thermocouple wire group 11, so that the first thermocouple wire 111 and the second thermocouple wire 112 are wound around the moving member 121 more, and the length of the thermocouple wire between the moving member 121 and the detecting head 113 is shortened, so that the detecting portion 113 moves towards the direction close to the first static member 1221, and finally the detecting portion 113 is tightly attached to the surface of the object to be detected. When the moving member 121 rotates in the reverse direction of the first direction, the first and second wires 111 and 112 are released from the outer surface of the moving member 121, i.e., the length of the thermocouple wire between the moving member 121 and the probe head 113 is increased, so that the probe portion 113 moves away from the first stationary member 1221, so as to sheath or separate the object to be measured. It will be appreciated that the first direction may be either clockwise or counterclockwise.

In order to enable the first and second wires 111 and 112 to be wound on the outer surface of the moving member 121 better, the outer surface of the moving member 121 may be provided with a spiral winding groove 1213, and the winding groove 1213 of the moving member 121 is used to receive the first and second wires 111 and 112.

When the first static member 1221 is a tubular static member, the first static member 1221 may further have a through hole 12211, the through hole 12211 communicating the inside of the first static member 1221 with the outside, the through hole 12211 being configured to allow the first thermocouple wire 111 and the second thermocouple wire 112 to pass out.

Specifically, the mover 121 includes a rod 1211 and an operation portion 1212, and the operation portion 1212 is disposed at one end of the rod 1211. The first static member 1221 and the second static member 1222 are tubular static members, the tubular first static member 1221 and the tubular second static member 1222 are arranged side by side, the rod 1211 is sleeved on the first static member 1221, the rod 1211 can move telescopically relative to the axial direction of the first static member 1221, the first thermocouple wire 111 and the second thermocouple wire 112 penetrate through the second static member 1222, the detection part 113, the cold end of the first thermocouple wire 111 and the cold end of the second thermocouple wire 112 are positioned outside the second static member 1222 and the moving member 121, and the first thermocouple wire 111 and the second thermocouple wire 112 are fixed on the moving member 121 locally.

For example, polyimide tape with back adhesive and thickness of 0.07mm to 0.1mm is selected to fix the first and second static members 1222 and keep their structures stable.

It should be noted that, in the case that the static member 122 includes a tubular structure, and at least a portion of the thermocouple wire between the moving member 121 and the detecting portion 113 needs to pass through the tubular structure, in order to prevent the detecting portion 115 from being pulled into the interior of the tubular structure by the moving member 121, in an example, referring to fig. 5, at least a portion of the detecting portion 113 may be biased toward a direction deviating from a central axis of the tubular structure, for example, at least a portion of the detecting portion 113 may be bent toward a radial direction of the first static member 1221 or the second static member 1222 in the static member 122.
