Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and 2, an embodiment of the present utility model provides a temperature measuring apparatus 100 for measuring a temperature of a measured object, which includes a heat generating element 201 of an aerosol generating device 200 (refer to fig. 3 or 9).

The temperature measuring device 100 comprises a bearing mechanism 10, an infrared temperature measuring mechanism 20 and a light guiding mechanism 30. The carrying mechanism 10 is used for carrying an object to be measured. The infrared temperature measuring mechanism 20 is used for being arranged at intervals with the measured object. At least a portion of the light guiding mechanism 30 is used adjacent to the heat generating member 201. The light guiding mechanism 30 can guide the infrared light emitted when the heating element 201 heats 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.

In the temperature measuring device 100 of the above embodiment, when measuring the temperature of the measured object, since at least part of the light guiding mechanism 30 is disposed adjacent to the heat generating element 201, the light guiding mechanism 30 can guide the infrared light emitted by the heat generating element 201 to the infrared temperature measuring mechanism 20, and the infrared temperature measuring mechanism 20 is used for detecting the temperature of the heat generating element 201 according to the infrared light incident to the infrared temperature measuring mechanism 20, since the temperature measuring device 100 does not need to contact with the measured object or the heat generating element 201 when measuring the temperature, on one hand, the temperature of the measured object or the heat generating element 201 is prevented from being easily affected due to the contact between the measured object or the heat generating element 201 and the temperature measuring device 100, the thermal damage is prevented, the temperature measuring accuracy of the temperature measuring device 100 for measuring the temperature of the heat generating element 201 or the measured object is improved, and on the other hand, the problem that the measured object or the heat generating element 201 is easily worn due to the contact with the temperature measuring device 100 is avoided.

It will be appreciated that at least a portion of the light guiding mechanism 30 (such as the light guiding element 31 in fig. 5) is adjacent to the heat generating element 201, meaning that at least a portion of the light guiding mechanism 30 is not in contact with the heat generating element 201, and at least a portion of the light guiding mechanism 30 is maintained at a predetermined distance from an outer wall or a hollow inner wall of the heat generating element 201, etc. For example, when at least part of the light guiding mechanism 30 is accommodated in the accommodating cavity of the heat generating element 201, at least part of the light guiding mechanism 30 may be disposed at a gap from the accommodating cavity, that is, at least part of the light guiding mechanism 30 maintains a predetermined distance from the hollow inner wall of the heat generating element 201; when at least part of the light guiding mechanism 30 is located outside the accommodating cavity, at least part of the light guiding mechanism 30 maintains a predetermined distance from the outer wall of the heat generating member 201. The preset distance is set so that at least part of the light guiding mechanism 30 can guide the infrared light emitted by the heating element 201 during heating 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.

In some embodiments, at least a portion of the light guiding mechanism 30 and the heat generating member 201 are movable relative to each other. In this way, the temperature measuring device 100 can measure the temperatures of different areas of the heating element 201 according to actual requirements. The relative position between at least part of the light guiding mechanism 30 and the heating element 201 can be adjusted during temperature measurement, so that at least part of the light guiding mechanism 30 is located at a target guiding position, and the target guiding position corresponds to a target region of the heating element 201, so that the light guiding mechanism 30 can guide 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.

Referring to fig. 3, in some embodiments, at least a portion of the light guiding mechanism 30 and the heat generating element 201 can move relative to each other in the axial direction of the heat generating element 201. In this way, the temperature measuring apparatus 100 can measure the temperature of a plurality of different portions of the heat generating member 201 in the axial direction. Illustratively, the heat generating member 201 includes a plurality of heat generating segments disposed at intervals along an axial direction of the heat generating member 201, and the temperature measuring apparatus 100 can accurately measure temperatures of each heat generating segment or a certain heat generating segment at a plurality of positions in the axial direction of the heat generating member 201.

Referring to fig. 3 and 4, in some embodiments, the aerosol-generating device 200 may further comprise 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 heat-generating member 201, the heat-generating member 201 comprising a smoke tube 2011 and a heat-generating body 2012 surrounding the inner and/or outer wall of the smoke tube 2011. The smoke tube 2011 is used for accommodating the cigarette 300, and the cigarette 300 can be a traditional cigarette or a special cigarette cartridge. The heating body 2012 comprises a plurality of heating sections, and each heating section is arranged on the inner wall and/or the outer wall of the smoke tube 2011 at intervals. Illustratively, the heat generating body 2012 includes a 1 st heat generating segment 20121 to an nth heat generating segment 2012N, the 1 st heat generating segment 20121 to the nth heat generating segment 2012N being arranged in sequence in a direction gradually away from the aerosol output end 202. The (i+1) th heat generating segment 2012 (i+1) is farther from the aerosol output end 202 than the i th heat generating segment 2012 i. Since at least part of the light guiding mechanism 30 and the heat generating member 201 can relatively move in the axial direction of the heat generating member 201, the relative position between at least part of the light guiding mechanism 30 and the heat generating member 201 can be adjusted in the axial direction of the heat generating member 201 to a target guiding position corresponding to a target heat generating section of the heat generating member 201, so that the light guiding mechanism 30 can guide the infrared light emitted from the target heat generating section to the infrared temperature measuring mechanism 20, and the infrared temperature measuring mechanism 20 can accurately measure the temperature of the target heat generating section according to the infrared light incident to the infrared temperature measuring mechanism 20.

Referring to fig. 4, the aerosol-output end 202 is illustratively detachably connected to the aerosol-generating body 203. Before temperature measurement, the aerosol output end 202 is detached from the aerosol generating main body 203, then the aerosol generating main body 203 is placed or mounted on the bearing mechanism 10, and the measured object or the heating element 201 is measured through the light guiding mechanism 30 and the infrared temperature measuring mechanism 20, so that the influence of the aerosol output end 202 on the path or energy of infrared light emitted from the light guiding element 31 can be reduced, and the accuracy of temperature measurement is further improved.

In other embodiments, when the temperature measuring device 100 measures the temperature of the heat generating element 201, the aerosol output end 202 may also be carried on the carrying mechanism 10 together with the aerosol-generating body 203, and the aerosol output end 202 is not detached from the aerosol-generating body 203.

It will be appreciated that the heat generating element 201 may be designed to any suitable shape, such as hollow tubular, other regular or irregular shapes, etc., as desired. The temperature measuring device 100 may only test the temperature of a certain section of the heating element 201, or may sequentially test the temperature of each section of the heating element 201.

Referring to fig. 1, in some embodiments, the temperature measurement apparatus 100 further includes a mounting member 40, and at least one of the light guiding mechanism 30 and the carrying mechanism 10 is disposed on the mounting member 40, so as to implement the mounting of at least one of the light guiding mechanism 30 and the carrying mechanism 10, and the whole machine is compact. At least one of at least part of the light guiding mechanism 30 and the carrying mechanism 10 is movable relative to the mounting member 40 so as to adjust the relative position between at least part of the light guiding mechanism 30 and the heat generating member 201 in the axial direction of the heat generating member 201.

Illustratively, the light guiding mechanism 30 and the carrying mechanism 10 may each be mounted on the mounting member 40, wherein at least part of the light guiding mechanism 30 may be movable relative to the mounting member 40, and the carrying mechanism 10 carrying the heat generating member 201 is fixed to the mounting member 40; or at least part of the light guiding mechanism 30 may be fixed to the mounting member 40, the carrying mechanism 10 being movable relative to the mounting member 40; still or at least part of the light guiding means 30 and the carrying means 10, respectively, may be movable relative to the mounting member 40. In this way, the relative position between at least part of the light guiding mechanism 30 and the bearing mechanism 10 can be conveniently adjusted along the axial direction of the heating element 201, so that the temperature of different positions of the heating element 201 borne by the bearing mechanism 10 can be measured.

Compared with a manual driving mode, the control module can automatically control the first driving piece 50 to work, so that the first driving piece 50 drives at least one of the light guiding mechanism 30 and the bearing mechanism 10 to move relative to the mounting piece 40, and therefore the relative position between at least part of the light guiding mechanism 30 and the heating piece 201 is accurately adjusted, and a guarantee is provided for accurately measuring the temperature of a target measured area of the heating piece 201. Illustratively, the control module includes a control circuit board or control circuit, or the like.

The limiting mechanism 60 is disposed on at least one of the carrying mechanism 10 and the light guiding mechanism 30, and is used for limiting the light guiding mechanism 30 and the carrying mechanism 10 to move further under the condition that the distance between the light guiding mechanism 30 and the carrying mechanism 10 reaches a threshold value, so as to control the movement between the light guiding mechanism 30 and the carrying mechanism 10 accurately, and further adjust the relative position between at least part of the light guiding mechanism 30 and the heating element 201 accurately, thereby providing a guarantee for testing the temperature of the target region of the heating element 201 accurately.

At least a portion of the light guiding mechanism 30 and the heat generating member 201 may be relatively rotated to a target guiding position corresponding to a target region of the heat generating member 201 in the circumferential direction at the time of temperature measurement, so that the light guiding mechanism 30 can guide infrared light emitted from the target region to the infrared temperature measuring mechanism 20, thereby enabling the infrared temperature measuring mechanism 20 to accurately measure the temperature of the target region of the heat generating member 201 in the circumferential direction according to infrared light incident to the infrared temperature measuring mechanism 20.

In some embodiments, at least one of the light guiding mechanism 30 and the carrying mechanism 10 is movable relative to the mounting member 40, so that at least part of the light guiding mechanism 30 and the heat generating member 201 can rotate relatively, and thus the relative position between at least part of the light guiding mechanism 30 and the heat generating member 201 can be adjusted along the circumferential direction of the heat generating member 201 according to actual test requirements. For example, at least a portion of the light guiding mechanism 30 can be movable or rotatable relative to the mounting member 40 such that at least a portion of the light guiding mechanism 30 can be rotatable relative to the heat generating member 201.

It will be appreciated that the link 33 may be driven in rotation relative to the position adjustment assembly 32 by a manual or powered source, such as a power motor.

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.

Referring to fig. 8 and 9, in some embodiments, at least one of the measured object and the heat generating element 201 is hollow, the connecting rod 33 is oriented along the axial direction of the heat generating element 201, and one end of the connecting rod 33 (i.e., the end of the connecting rod 33 near the light guiding element 31) can extend into at least one of the measured object and the heat generating element 201, so that the light guiding element 31 can extend into at least one of the measured object or the heat generating element 201.

In other embodiments, the light guiding element 31 may not be located in the heat generating element 201 or the object to be measured during temperature measurement, for example, the light guiding element 31 is located outside the heat generating element 201 or the object to be measured during temperature measurement, the light guiding element 31 is not in contact with the outer wall of the heat generating element 201 (or the object to be measured), and the light guiding element 31 is capable of guiding the infrared light emitted by the heat generating element 201 to the infrared temperature measuring mechanism 20.

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 heat generating element 201. Since the infrared light emitted by the heat generating element 201 is invisible light, before temperature measurement, the visible light (such as laser) needs to be emitted to the light guiding element 31 by the calibration light source, and the position of the connecting rod 33 in the X-axis direction, the Y-axis direction and the Z-axis direction is adjusted by the position adjusting component 32 or the second driving element, 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 guided by the light guiding element 31 and then vertically incident to a point of the target receiving area of the heat generating element 201, and by observing the position of the visible light on the heat generating element 21, the infrared light received by the infrared temperature measuring mechanism 20 is obtained as the infrared light emitted by a point of the heat generating element 21, for example, when the visible light is at a point of the target receiving area of the heat generating element 201, the infrared light emitted by the point of the target area to be measured can be determined to be guided to the infrared temperature measuring mechanism 20 by the light guiding element 31, so that the infrared light received by the infrared temperature measuring mechanism 20 is ensured to be received from the target is provided for improving the temperature measurement guarantee of the temperature measurement equipment 100.

The light condensing element is arranged between the infrared sensor and the light guiding element 31 of the light guiding mechanism 30, and is used for condensing the light guided out by the light guiding element 31 to the infrared sensor. The focal length of the condensing element is equal to the distance between the condensing element and the center of the light guiding element 31, so that the infrared temperature measuring mechanism 20 detects infrared light at a certain point of the target area of the heating element 201, rather than infrared light with a large area, and further temperature measurement is more accurate.

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

Referring to FIG. 5, in some embodiments, the mounting member 40 includes a guide rail 41, and the light guiding mechanism 30, the carrying mechanism 10 and the infrared thermometric mechanism 20 are movably mounted on the guide rail 41. In this way, when the target region of the heating element 201 is calibrated before temperature measurement, at least one of the carrying mechanism 10 and the infrared temperature measuring mechanism 20 can be moved relative to the guide rail 41. At least one of the light guiding mechanism 30 and the carrying mechanism 10 may also be moved relative to the guide rail 41 before thermometry to coarsely adjust the relative position between the light guiding element 31 of the light guiding mechanism 30 and the heat generating element 201. It can be appreciated that, before temperature measurement, the heights of the light guiding mechanism 30, the bearing mechanism 10 and the infrared temperature measuring mechanism 20 can be adjusted by using a cushion block or the like, so that the heights of the three are the same, and the light guided out by the light guiding mechanism 30 can reach the infrared temperature measuring mechanism 20 as much as possible, thereby improving the temperature measurement accuracy of the temperature measuring device 100.

Wherein the heating element 201 is used for circumferentially heating the aerosol-generating substrate such as the cigarette 300 to generate aerosol.

In the temperature measurement system of the above embodiment, when the temperature measurement device 100 measures the temperature of the measured object, since at least part of the light guiding mechanism 30 is disposed adjacent to the heat generating element 201, the light guiding mechanism 30 can guide the infrared light emitted by the heat generating element 201 to the infrared temperature measuring mechanism 20, and the infrared temperature measuring mechanism 20 is used for detecting the temperature of the heat generating element 201 according to the infrared light incident to the infrared temperature measuring mechanism 20, since the temperature measurement device 100 does not need to contact with the measured object or the heat generating element 201 when measuring the temperature, on one hand, the temperature of the measured object or the heat generating element is prevented from being easily affected due to the contact between the measured object or the heat generating element 201 and the temperature measurement device 100, thermal damage is prevented, and on the other hand, the temperature measurement accuracy of the measured object or the heat generating element for measuring the temperature is prevented from being easily worn due to the contact with the temperature measurement device.
