技术领域technical field
本实用新型涉及烟具领域，特别是涉及一种发热组件、雾化器及电子烟。The utility model relates to the field of smoking sets, in particular to a heating component, an atomizer and an electronic cigarette.
背景技术Background technique
随着科技进步和人们对健康生活的追求，电子烟越来越受到人们的青睐。为了提供给消费者较好的用户体验，电子烟内部通常设置有温度检测模块，以监测吸烟过程的烟油雾化温度，避免烧焦等现象出现。With the advancement of science and technology and people's pursuit of a healthy life, electronic cigarettes are becoming more and more popular. In order to provide consumers with a better user experience, a temperature detection module is usually installed inside the e-cigarette to monitor the atomization temperature of the e-liquid during the smoking process and avoid scorching and other phenomena.
然而，现有的电子烟中，发热体与温度检测元件通常是独立设置，分别组装的。温度检测元件设置的位置直接影响测量结果的准确性，容易出现温度检测元件不能准确反映吸烟过程的烟油雾化温度的现象。在烟油用完或者烟油供应不足时，容易出现干烧现象，导致糊味，从而影响用户体验。而且，发热体与温度检测元件需要分别组装，组装比较复杂，成品合格率比较低。However, in the existing electronic cigarettes, the heating element and the temperature detection element are usually arranged independently and assembled separately. The location of the temperature detection element directly affects the accuracy of the measurement results, and it is prone to the phenomenon that the temperature detection element cannot accurately reflect the atomization temperature of the e-liquid during the smoking process. When the e-liquid is used up or the supply of e-liquid is insufficient, it is prone to dry burning, resulting in a burnt smell, which affects the user experience. Moreover, the heating element and the temperature detection element need to be assembled separately, the assembly is relatively complicated, and the qualified rate of finished products is relatively low.

The heating element 142 further includes a heating element 1422 and a temperature detecting element 1423 formed on a surface of the ceramic substrate 1421 .

The bracket 146 is made of materials such as silica gel, which can also prevent the oil on the oil guiding body 144 from leaking.
发热组件14与底座15的连接方式具体如下。底座15的两侧分别设有第一连接件156与第二连接件154，第一连接件156为插槽，类似电脑内存条插槽，发热体142的导电端子插接在插槽内，实现电连接。第二连接件154用于与供电装置实现机械连接和电连接。The connection manner between the heating component 14 and the base 15 is specifically as follows.

When the ceramic substrate 1421 is a porous ceramic, it can guide oil, and the oil guide body 144 can be omitted in this case. In this embodiment, the ceramic substrate 1421 is flat, and in other embodiments, it may also be cylindrical or other irregular shapes.
如图6所示，本实用新型第二实施例提供的电子烟300包括雾化器100及供电装置200。雾化器100与供电装置200可拆卸连接，供电装置200用于为雾化器100提供工作电源。供电装置200上设置有开关按键202。供电装置包括电池和微控制器（图未示）等。As shown in FIG. 6 , the electronic cigarette 300 provided by the second embodiment of the present invention includes an atomizer 100 and a power supply device 200 .

The power supply device 200 is provided with a switch button 202 . The power supply device includes a battery and a microcontroller (not shown in the figure) and so on.
请一起参阅图1-3及图7，当按下开关按键202时，发热体142通电发热，对导油体144内的烟油加热雾化，用户通过吸嘴部件11可以吸食烟雾。随着发热部1427的继续发热，发热表面上的温度（烟油雾化温度）不断升高，发热组件14内的温度检测元件1423中热敏电阻层的电阻会随着温度变化而改变，在本实施方式中，热敏电阻层为钨钼锰合金，其阻值温度变化系数大致是线性的，如图7所示。供电装置200的微控制器通过检测电流或者电压变化来有效实时监测烟油雾化温度的变化。当发热表面上的温度过高时，可控制停止发热元件工作或者降低输出功率，避免导油体144等部件烧焦而产生糊味。Please refer to FIG. 1-3 and FIG. 7 together. When the switch button 202 is pressed, the heating element 142 is energized to heat and atomize the e-liquid in the oil guide body 144 . As the heating part 1427 continues to generate heat, the temperature on the heating surface (vapor oil atomization temperature) continues to rise, and the resistance of the thermistor layer in the temperature detection element 1423 in the heating component 14 will change with the temperature. In this embodiment, the thermistor layer is a tungsten-molybdenum-manganese alloy, and its resistance temperature variation coefficient is approximately linear, as shown in FIG. 7 . The microcontroller of the power supply device 200 effectively monitors the change of the atomization temperature of the e-liquid in real time by detecting the change of current or voltage. When the temperature on the heating surface is too high, the heating element can be controlled to stop working or the output power can be reduced, so as to avoid burning of parts such as the oil guiding body 144 and produce a burnt smell.
本实用新型的发热组件整合了发热元件及温度检测元件，温度检测元件可以准确反映雾化器吸烟过程中烟油雾化温度，可以有效防止雾化器干烧的现象。而且，发热组件组装方便，良率高。The heating component of the utility model integrates a heating element and a temperature detection element, and the temperature detection element can accurately reflect the atomization temperature of the smoke oil during the smoking process of the atomizer, and can effectively prevent the phenomenon of dry burning of the atomizer. Moreover, the heating components are easy to assemble and have a high yield.
