本申请实施例涉及测温装置技术领域，特别是涉及一种加热组件及气溶胶生成装置。The embodiments of the present application relate to the technical field of temperature measuring devices, and in particular to a heating component and an aerosol generating device.
背景技术Background technique
在气溶胶生成装置领域，通常需要对气溶胶生成装置中的发热管进行测温以控制加热温度。现有的一些周向红外发热管采用NTC或PTC热敏电阻贴于发热管的外壁测温。其中热敏电阻通常采用树脂或玻璃封装测温芯片，导致封装完成后测温头部直径大，热敏电阻检测的温度通常滞后于发热管的温度，为减轻测温延迟，通常会降低发热体升温速度，但这样会导致烟支预热时间长，影响加热效率。为此，通常采用热电偶来代替热敏电阻来检测发热管的温度，为了防止发热管上的电流干扰热电偶工作，通常需要在热电偶和发热管之间设置绝缘层，通常为有机硅绝缘层。但是，目前有机硅绝缘层一方面成本较高，另一方面有机硅绝缘层具有较小的厚度，从而在热电偶与之连接后，容易造成绝缘层脱落，从而导致热电偶与发热管之间的绝缘不可靠。In the field of aerosol generating devices, it is usually necessary to measure the temperature of the heating tube in the aerosol generating device to control the heating temperature. Some existing circumferential infrared heating tubes use NTC or PTC thermistors attached to the outer wall of the heating tube for temperature measurement. Among them, the thermistor usually uses a resin or glass packaged temperature measuring chip, which results in a large diameter of the temperature measuring head after the package is completed. The temperature detected by the thermistor usually lags behind the temperature of the heating tube. In order to reduce the temperature measurement delay, the heating element heating rate is usually reduced, but this will cause the cigarette to preheat for a long time and affect the heating efficiency. For this reason, thermocouples are usually used instead of thermistors to detect the temperature of the heating tube. In order to prevent the current on the heating tube from interfering with the operation of the thermocouple, it is usually necessary to set an insulating layer between the thermocouple and the heating tube, usually a silicone insulating layer. However, at present, the silicone insulating layer is relatively expensive on the one hand, and the silicone insulating layer has a relatively small thickness on the other hand, so that after the thermocouple is connected to it, it is easy to cause the insulating layer to fall off, resulting in unreliable insulation between the thermocouple and the heating tube.

请参阅图1至图4，加热组件100包括加热管10、热电偶20、绝缘套30和固定件40。加热管10内具有容纳腔11，容纳腔11用于容纳气溶胶生成制品的至少局部，加热管10用于加热气溶胶生成制品以使气溶胶生成制品产生气溶胶。热电偶20的测温头21设置在加热管10上，以测量加热管10上的温度从而实现温度的调控。绝缘套30设置在加热管10和热电偶20之间起绝缘的作用，避免加热管10上的电流对热电偶20产生影响，提高测温准确性。固定件40用于将热电偶20相对于加热管10固定，避免热电偶20移动而影响温度检测。Please refer to Figures 1 to 4. The heating assembly 100 includes a heating tube 10, a thermocouple 20, an insulating sleeve 30 and a fixing member 40. The heating tube 10 has a housing chamber 11 therein, and the housing chamber 11 is used to accommodate at least a portion of the aerosol generating product. The heating tube 10 is used to heat the aerosol generating product so that the aerosol generating product generates an aerosol. The temperature measuring head 21 of the thermocouple 20 is arranged on the heating tube 10 to measure the temperature on the heating tube 10 so as to achieve temperature control. The insulating sleeve 30 is arranged between the heating tube 10 and the thermocouple 20 to play an insulating role, so as to prevent the current on the heating tube 10 from affecting the thermocouple 20 and improve the accuracy of temperature measurement. The fixing member 40 is used to fix the thermocouple 20 relative to the heating tube 10 to prevent the thermocouple 20 from moving and affecting the temperature detection.
作为一种示例，加热管10被配置为能够产生焦耳热，基于此，加热管10的可以包含电阻材料，合适的电阻材料包含但不限于：半导体，如掺杂陶瓷、导电陶瓷(例如二硅化钼)、碳、石墨、金属、金属合金以及由陶瓷材料和金属材料制成的复合材料。As an example, the heating tube 10 is configured to generate Joule heat. Based on this, the heating tube 10 may include a resistive material. Suitable resistive materials include but are not limited to: semiconductors, such as doped ceramics, conductive ceramics (such as molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic materials and metal materials.
作为一种示例，加热管10被配置为能够在变化的磁场中发热，基于此，加热管10包含感受材料。感受材料可以包括金属或碳。在一实施例中，感受材料可包括铁磁性材料，例如铁素体、铁磁性钢或不锈钢。在一实施例中，感受材料包括镍铁合金。在一实施例中，感受材料包括400系列不锈钢，400系列不锈钢包括410级或420级或430级不锈钢。As an example, the heating tube 10 is configured to generate heat in a changing magnetic field, based on which the heating tube 10 includes a sensing material. The sensing material may include metal or carbon. In one embodiment, the sensing material may include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In one embodiment, the sensing material includes a nickel-iron alloy. In one embodiment, the sensing material includes 400 series stainless steel, which includes 410 grade, 420 grade, or 430 grade stainless steel.
作为一种示例，加热管10包括基体13和设置在基体上13的发热层12，容纳腔11形成在基体13中。发热层12可以包含电阻材料或者包含红外涂层，红外涂层用于产生红外线。为了简化工艺，可以将发热层12设置在基体13的外表面上。在发热层12包含红外涂层时，可以使基体13是透明的，使得红外线能够穿过基体13射向容纳腔11中的气溶胶生成制品，从而加热气溶胶生成制品。在发热层12包含电阻材料时，该发热层12可以形成涂层或者膜附在基体13的表面上。As an example, the heating tube 10 includes a substrate 13 and a heating layer 12 disposed on the substrate 13, and the accommodating cavity 11 is formed in the substrate 13. The heating layer 12 may contain a resistive material or an infrared coating, and the infrared coating is used to generate infrared rays. In order to simplify the process, the heating layer 12 may be disposed on the outer surface of the substrate 13. When the heating layer 12 contains an infrared coating, the substrate 13 may be transparent so that the infrared rays can pass through the substrate 13 and project toward the aerosol generating product in the accommodating cavity 11, thereby heating the aerosol generating product. When the heating layer 12 contains a resistive material, the heating layer 12 may form a coating or a film attached to the surface of the substrate 13.
作为一种示例，请参阅图1和图4，绝缘套30套在加热管10至少局部的外围，例如套在加热管10外表面上的发热层12的至少局部上，热电偶20包括测温头21，测温头21连接在绝缘套30上，即测温头21通过绝缘套30与加热管10绝缘且间隔设置。固定件40分别与测温头21和加热管10或者绝缘层连接，使得测温头21夹设于固定件40与加热管10之间，从而将测温头21相对于加热管10固定。As an example, referring to FIG. 1 and FIG. 4 , the insulating sleeve 30 is sleeved on at least a part of the periphery of the heating tube 10, for example, on at least a part of the heating layer 12 on the outer surface of the heating tube 10, and the thermocouple 20 includes a temperature measuring head 21, and the temperature measuring head 21 is connected to the insulating sleeve 30, that is, the temperature measuring head 21 is insulated from the heating tube 10 by the insulating sleeve 30 and is arranged at intervals. The fixing member 40 is respectively connected to the temperature measuring head 21 and the heating tube 10 or the insulating layer, so that the temperature measuring head 21 is sandwiched between the fixing member 40 and the heating tube 10, thereby fixing the temperature measuring head 21 relative to the heating tube 10.
当然，在其他的示例中，如图5所示，绝缘套30也可以套设在测温头21的外围，对测温头21进行至少局部的包裹，同样也可以使得加热管10与测温头21之间形成绝缘间隔。Of course, in other examples, as shown in FIG. 5 , the insulating sleeve 30 may also be sleeved around the periphery of the temperature measuring head 21 to at least partially wrap the temperature measuring head 21 , and also form an insulating gap between the heating tube 10 and the temperature measuring head 21 .
在一些实施例中，请参阅图4，沿所述加热管10的径向方向，所述绝缘套30的厚度H满足：0.01mm≤H≤0.2mm。绝缘层通常具有一定的厚度，在本实施例中，在满足绝缘层具有良好的绝缘效果的前提下，要求绝缘层具有较小的厚度，一方面，相对厚度较大的绝缘层，厚度较小的绝缘层能够吸收更少的热量，从而有助于降低加热管10的功耗；另一方面，较小厚度的绝缘层具有更高的热传递效率，有助于测温头21感测的温度与加热管10的实际温度同步，有助于防止热电偶20感测温度发生迟延，对提升温度检测的实时性和准确性有帮助。In some embodiments, please refer to FIG. 4 , along the radial direction of the heating tube 10 , the thickness H of the insulating sleeve 30 satisfies: 0.01mm≤H≤0.2mm. The insulating layer usually has a certain thickness. In this embodiment, on the premise that the insulating layer has a good insulating effect, the insulating layer is required to have a smaller thickness. On the one hand, the insulating layer with a smaller thickness can absorb less heat than the insulating layer with a larger thickness, thereby helping to reduce the power consumption of the heating tube 10; on the other hand, the insulating layer with a smaller thickness has a higher heat transfer efficiency, which helps to synchronize the temperature sensed by the temperature measuring head 21 with the actual temperature of the heating tube 10, helps to prevent the delay in the temperature sensing by the thermocouple 20, and helps to improve the real-time and accuracy of temperature detection.
绝缘套30可以由高温胶带环绕加热管10或测温头21形成，高温胶带不仅耐高温而且具有较小的厚度，其单层厚度可以为0.08mm、0.13mm或0.18mm，或者可以为0.055mm、0.060mm、0.070mm、0.080mm、0.10mm、0.12mm、0.13mm。The insulating sleeve 30 can be formed by high-temperature tape surrounding the heating tube 10 or the temperature measuring head 21. The high-temperature tape is not only resistant to high temperatures but also has a smaller thickness. The single-layer thickness can be 0.08mm, 0.13mm or 0.18mm, or can be 0.055mm, 0.060mm, 0.070mm, 0.080mm, 0.10mm, 0.12mm, 0.13mm.
绝缘套30可以包括1-3层高温胶带。The insulating sleeve 30 may include 1-3 layers of high temperature tape.
在一些实施例中，请参阅图2和图3，加热组件100还包括定位件50，定位件50用于使得测温头21能够快速定位并且安装在加热管10的指定位置上，提高测温头21的安装精度。作为一种示例，定位件50设置在加热管10和固定件40之间，定位件50可以通过固定件40保持在加热管10，定位件50上开设有定位槽51，定位槽51暴露发热层12的局部，测温头21的局部嵌合在定位槽51中，测温头21的局部凸伸至定位槽51之外，并且被固定件40挤压，从而使得测温头21紧贴加热管10的表面。即沿加热管10的径向方向，测温头21的厚度大于定位件50的厚度，从而保证测温头21能够与固定件40接触。In some embodiments, please refer to FIG. 2 and FIG. 3 , the heating assembly 100 further includes a positioning member 50, which is used to enable the temperature measuring head 21 to be quickly positioned and installed at a designated position of the heating tube 10, thereby improving the installation accuracy of the temperature measuring head 21. As an example, the positioning member 50 is disposed between the heating tube 10 and the fixing member 40, and the positioning member 50 can be retained on the heating tube 10 by the fixing member 40. A positioning groove 51 is provided on the positioning member 50, and the positioning groove 51 exposes a part of the heating layer 12, and a part of the temperature measuring head 21 is embedded in the positioning groove 51, and a part of the temperature measuring head 21 protrudes out of the positioning groove 51 and is squeezed by the fixing member 40, so that the temperature measuring head 21 is closely attached to the surface of the heating tube 10. That is, along the radial direction of the heating tube 10, the thickness of the temperature measuring head 21 is greater than the thickness of the positioning member 50, thereby ensuring that the temperature measuring head 21 can contact with the fixing member 40.
在一些实施例中，定位件50包括隔热材料，例如气凝胶片、气凝泡棉等，至少局部由隔热材料制成的定位件50设置在发热层12上，一方面可以定位和固定测温头21，另一方面可以降低发热层12上的热量散失，降低加热组件100的功耗，同时还能够对加热管10的至少部分外表面形成绝缘保护。In some embodiments, the positioning member 50 includes a thermal insulation material, such as an aerogel sheet, aerogel foam, etc. The positioning member 50, which is at least partially made of a thermal insulation material, is arranged on the heating layer 12. On the one hand, it can position and fix the temperature measuring head 21, and on the other hand, it can reduce the heat loss on the heating layer 12 and reduce the power consumption of the heating component 100. At the same time, it can also form insulation protection for at least part of the outer surface of the heating tube 10.
在一些实施例中，请参阅图1，在加热管10的轴向方向上，定位件50的长度大于或者等于发热层12的长度，并且定位件50覆盖发热层12。通过将定位件50与发热层12重叠或者定位件50完全将发热层12包裹，可以有效降低加热组件100的功耗。In some embodiments, referring to FIG1 , in the axial direction of the heating tube 10, the length of the positioning member 50 is greater than or equal to the length of the heating layer 12, and the positioning member 50 covers the heating layer 12. By overlapping the positioning member 50 with the heating layer 12 or completely wrapping the heating layer 12 with the positioning member 50, the power consumption of the heating assembly 100 can be effectively reduced.
在一些实施例中，请参阅图1和图2，定位件50上的定位槽51呈长条状，沿定位件50的轴向方向，定位槽51的第一端可以位于加热管10的中间区域，优选第一端对应加热管10的热量集中区域设置，定位槽51中与第一端相对的第二端沿直线延伸至定位件50的端部。测温头21抵接在定位槽51的第一端。热电偶20还包括第一线缆22和第二线缆23，其中第一线缆22和第二线缆23均与测温头21电连接，第一线缆22的局部和第二线缆23的局部位于定位槽51内。第一线缆22和第二线缆23是由不同材料制成的热电偶丝，测温头21可以由第一线缆22和第二线缆23的端部相互连接形成。通过设置长条状的定位槽51，可以使得热电偶20的第一线缆22和第二线缆23能够收容在定位槽51中，有效减少加热组件100的径向方向的尺寸，有助于确保加热组件表面的一致性。值得说明的是，测温头21的厚度大于第一线缆22和/或者第二线缆23的直径，从而使得测温头21能够充分与发热层12接触，避免测温头21被第一线缆22和/或者第二线缆23架起而影响测温头21的测温。In some embodiments, please refer to FIG. 1 and FIG. 2 , the positioning groove 51 on the positioning member 50 is in the shape of an elongated strip. Along the axial direction of the positioning member 50, the first end of the positioning groove 51 can be located in the middle area of the heating tube 10. Preferably, the first end is arranged corresponding to the heat concentration area of the heating tube 10, and the second end of the positioning groove 51 opposite to the first end extends in a straight line to the end of the positioning member 50. The temperature measuring head 21 abuts against the first end of the positioning groove 51. The thermocouple 20 also includes a first cable 22 and a second cable 23, wherein the first cable 22 and the second cable 23 are both electrically connected to the temperature measuring head 21, and a part of the first cable 22 and a part of the second cable 23 are located in the positioning groove 51. The first cable 22 and the second cable 23 are thermocouple wires made of different materials, and the temperature measuring head 21 can be formed by connecting the ends of the first cable 22 and the second cable 23 to each other. By providing the long strip positioning groove 51, the first cable 22 and the second cable 23 of the thermocouple 20 can be accommodated in the positioning groove 51, effectively reducing the radial dimension of the heating component 100, and helping to ensure the consistency of the surface of the heating component. It is worth noting that the thickness of the temperature measuring head 21 is greater than the diameter of the first cable 22 and/or the second cable 23, so that the temperature measuring head 21 can fully contact with the heating layer 12, avoiding the temperature measuring head 21 being lifted by the first cable 22 and/or the second cable 23 and affecting the temperature measurement of the temperature measuring head 21.
当然，在其他的实施例中，定位槽51不一定沿加热管10的轴向方向延伸，定位槽51可以呈螺旋状，第一线缆22和第二线缆23可以收容在螺旋状的定位槽51中。Of course, in other embodiments, the positioning groove 51 does not necessarily extend along the axial direction of the heating tube 10 , and the positioning groove 51 may be spirally shaped, and the first cable 22 and the second cable 23 may be received in the spirally shaped positioning groove 51 .
在一些实施例中，固定件40包括高温胶带，高温胶带周向缠绕在定位件50的外围，高温胶带把测温头21固定在定位槽51中，并且向测温头21提供压力以使得测温头21抵接在发热层12上。在其他的实施例中，固定件40可以是热缩管，热缩管套设在定位件50的外围，经过高温加热之后，热缩管收缩并将测温头21固定在定位槽51中，并且与发热层12抵接。In some embodiments, the fixing member 40 includes a high temperature tape, which is circumferentially wound around the periphery of the positioning member 50. The high temperature tape fixes the temperature measuring head 21 in the positioning groove 51 and provides pressure to the temperature measuring head 21 so that the temperature measuring head 21 abuts against the heating layer 12. In other embodiments, the fixing member 40 may be a heat shrink tube, which is sleeved around the periphery of the positioning member 50. After high temperature heating, the heat shrink tube shrinks and fixes the temperature measuring head 21 in the positioning groove 51 and abuts against the heating layer 12.
本申请又提供气溶胶生成装置实施例，气溶胶生成装置包括上述的加热组件100，对于加热组件100的具体结构和功能可参阅上述实施例，此处不再赘述。The present application further provides an embodiment of an aerosol generating device, which includes the above-mentioned heating component 100. The specific structure and function of the heating component 100 can be found in the above-mentioned embodiment and will not be described in detail here.
本申请实施例加热组件100包括表面具有发热层12的加热管10和具有测温头21的热电偶20，绝缘套30为发热层12与测温头21提供绝缘间隔，固定件40提供作用力使测温头21抵接加热管10，因此既能够将热电偶20固定在加热管10上，又能够确保发热层12完整，有助于增加加热管10的加热均匀性和提升温度检测的准确性。并且相比热敏电阻，热电偶20不仅成本更低，而且灵敏度更高，能够更及时的反馈实时的检测温度。The heating assembly 100 of the embodiment of the present application includes a heating tube 10 with a heating layer 12 on the surface and a thermocouple 20 with a temperature measuring head 21. The insulating sleeve 30 provides an insulating interval between the heating layer 12 and the temperature measuring head 21. The fixing member 40 provides a force to make the temperature measuring head 21 abut against the heating tube 10. Therefore, the thermocouple 20 can be fixed on the heating tube 10 and the heating layer 12 can be ensured to be intact, which helps to increase the heating uniformity of the heating tube 10 and improve the accuracy of temperature detection. Compared with thermistors, the thermocouple 20 is not only cheaper, but also more sensitive, and can provide more timely feedback of the real-time detection temperature.
