Description

加热器件及电子雾化装置 技术领域
本申请涉及电子雾化技术领域，特别是涉及加热器件及电子雾化装置。
背景技术
气溶胶是一种由固体或液体小质点分散并悬浮在气体介质中形成的胶体分散体系，由于气溶胶可通过呼吸系统被人体吸收，为用户提供一种新型的替代吸收方式，例如可对草本类或膏类的气溶胶生成基质烘烤加热而产生气溶胶的雾化装置，应用于不同领域中，为用户递送可供吸入的气溶胶，替代常规的产品形态及吸收方式。
现有的烘烤型电子雾化装置还可通过电磁感应原理使发热件产生热量来烘烤加热雾化气溶胶生成基质。但是，通过发热件加热时，若发热件发出的局部高温容易烤焦气溶胶生成基质，影响用户吸入口感。
发明内容
有鉴于此，针对传统的发热件容易烤焦气溶胶生成基质的问题，提供一种加热器件及电子雾化装置。

参阅图1-图2，本实用新型一实施例中，提供一种加热器件100，加热器件100应用于电子雾化装置中，可用于加热雾化花叶类、草本类或膏类的气溶胶生成基质。
加热器件100包括基座10、电磁线圈30及红外辐射件50，基座10上形成有相互独立且相邻的隔热腔11和容置腔13，电磁线圈30设于基座10上，红外辐射件50设于隔热 腔11内。红外辐射件50包括感应体52和红外辐射层54，感应体52被构造为在电磁线圈30的电磁感应作用下发热；红外辐射层54涂覆于感应体52朝向容置腔13的表面，且被构造为吸收感应体52的热量，并向容置腔13内的待加热体辐射红外线。当电磁线圈30通入交变电流形成磁场后，感应体52在电磁感应作用下发热，进而使涂覆在感应体52上的红外辐射层54受热后向容置腔13辐射红外线，以利用红外线加热容置腔13内的气溶胶生成基质，来进行气溶胶生成基质雾化。
红外辐射件50的感应体52设于隔热腔11内，且与隔热腔11的腔壁间隔设置，以将红外辐射件50隔热装配。当感应体52在电磁线圈30的作用下发热时，红外辐射件50整体发热，但是红外发热体与隔热腔11的内壁间隔设置，不会将热量直接传递给基座10，防止基座10本身热量过高而烤焦容置腔13内的气溶胶生成基质。而且，隔热腔11内部隔热设置，红外辐射件50产生的热量无法通过隔热腔11内部的传递至基座10，进一步防止基座10温度升高而烤焦气溶胶生成基质。如此，只利用红外辐射层54辐射的红外线来加热容置腔13内的气溶胶生成基质，可以最大化的利用红外加热方式来在抽吸初始阶段提供高温烘烤，同时不会使基座10发热而烤焦气溶胶生成基质，降低气溶胶生成基质预热时间，同时保证抽吸口感。
另外，充分发挥红外加热优势，可短时高温加热气溶胶生成基质，可雾化更多短波段类型的介质，丰富雾化口感。并且，电磁加热方式只需在座体161上设置电磁线圈30，无需在雾化芯上制作发热膜层，简化雾化芯的制作。
一些实施例中，隔热腔11为真空腔，隔热腔11内抽真空没有空气介质，隔热腔11内没有导热介质引导红外辐射件50发出的热量向基座10传递，将红外辐射件50隔热装配，防止基座10接收到红外防辐射体发出的热辐射而升温。另一些实施例中，隔热腔11内填充的气体的导热率小于空气的导热率，即隔热腔11内气体的导热率较低，例如隔热腔11内填充卤化物气体，红外辐射件50发出的热辐射较少的通过隔热腔11内的气体传递至 基座10，防止基座10本身的温度过高而烤焦气溶胶生成基质。
一些实施例中，基座10上沿第一方向延伸形成容置腔13，隔热腔11绕第一方向所在的轴线包围于容置腔13外，电磁线圈30围绕隔热腔11缠绕于基座10外周。电磁线圈30可通过电磁感应原理使隔热腔11内的感应体52发热，感应体52发热后使红外辐射层54发热红外线，而隔热腔11包围于容置腔13外，红外辐射层54辐射的红外线可传递至容置腔13内加热雾化气溶胶生成基质。
具体地，红外辐射件50设有红外辐射层54的一侧与隔热腔11的腔壁之间间隔设置，且红外辐射件50背向红外辐射层54的一侧与隔热腔11的腔壁之间间隔设置。也就是说，红外辐射件50的正反两面均与隔热腔11的腔壁之间间隔设置，防止红外辐射件50与基座10接触而传递热量。
进一步地，基座10包括第一公用腔壁121及外周壁123，第一公用腔壁121围合形成容置腔13，外周壁123与第一公用腔壁121连接，且外周壁123与第一公用腔壁121之间围合形成隔热腔11，基座10上至少第一公用腔壁121透明设置。如此，可允许隔热腔11内的红外辐射件50发出红外线后透过基座10传递至容置腔13内。
具体地，外周壁123和第一公用腔壁121均透明设置，相当于将基座10整体透明设置，方便生产制造基座10。并且，外周壁123面向隔热腔12的内壁或外周壁123背向隔热腔12的外壁涂覆有反射层，相当于反射层60围设于隔热腔11背离容置腔13的一侧。当隔热腔11内的红外辐射层54朝向容置腔13辐射红外线时，会有部分红外线向背向容置腔13的一侧的外周壁123传递，此时可通过涂覆于外周壁123内外侧中至少一侧的反射层60将这部分红外线反射回容置腔13内，提高红外线的利用率。
可选地，基座10由石英石制成，石英石为透明件且耐高温，不会因为气溶胶生成基质温度较高而受损，同时透明的石英石基座10可以使红外辐射件50向容置腔13辐射红外线。
参阅图3，具体地，红外辐射件50上开设有若干通孔51，每个通孔51允许由反射层60反射的红外线通过。如此，利用通孔51允许反射层60反射回的红外线可直接穿过红外辐射件50传递至容置腔13内，方便通过反射层60反射回收红外线，进一步提高对容置腔13内气溶胶生成基质的红外线加热效率。例如，通孔51开设有多个，每个通孔51沿第一方向延伸开设。
可选地，感应体52背向红外辐射层54的一面的粗糙度小于，感应体52涂覆红外辐射层54一面的粗糙度，即感应体52背向红外辐射层54的一面较为光亮，以降低该面的热辐射系数，进而使更多的热辐射传递至红外辐射层54，进而提高红外辐射层54的辐射率，提高红外加热效率。
参阅图4-图5，另一些实施例中，基座10包括套筒141和内胆143，内胆143为透明件，内胆143内形成有隔热腔11；内胆143至少部分套设于套筒141内，内胆143与套筒141之间形成有容置腔13。这样，可以将气溶胶生成基质插装于内胆143上并伸入容置腔13内，内胆143的隔热腔11内设置红外辐射件50，电磁线圈30绕隔热腔11绕设于套筒141外周，红外辐射件50在电磁线圈30的作用下辐射的红外线，红外线可以穿过透明的内胆143传递至容置腔13内，进而加热雾化容置腔13内的气溶胶生成基质。
可选地，内胆143由石英石制成，石英石为透明件且耐高温，不会因为气溶胶生成基质温度较高而受损，同时透明的石英石内胆143可以使红外辐射件50向容置腔13辐射红外线。
进一步地，内胆143伸入容置腔13的端部呈尖端状设置，以方便气溶胶生成基质插装于内胆143上。
参阅图6-图7，又一些实施例中，基座10包括座体161和盖体163，座体161一侧形成有容置腔13，盖体163密封盖设于座体161的另一侧，座体161与盖体163之间密封形成隔热腔11，电磁线圈30盘设于盖体163背向座体161的表面。这样，可以将红外辐射 件50设于盖体163与座体161之间密封形成的隔热腔11内，盖体163背面的电磁线圈30可以通过电磁感应，将红外辐射件50加热并辐射红外线，隔热腔11内的红外线可传递至基座10另一侧的容置腔13内，以加热雾化容置腔13内的气溶胶生成基质。
进一步地，座体161具有分隔隔热腔11与容置腔13的第二公用腔壁162，座体10上至少第二公用腔壁162透明设置，以允许隔热腔11内红外辐射件50发出的红外线，可穿过透明的第二公用腔壁162传递至容置腔13内。并且，盖体163面向隔热腔11的表面涂覆有反射层60，红外辐射件50发出的部分红外线朝向盖体163传递，这部分红外线被被盖体163上的反射层60反射至容置腔13内，提高红外线的利用率。
具体地，座体161整体为透明件，座体161一侧隔热腔11内红外辐射件50发出的红外线，可穿过透明的座体161传递至容置腔13内。可选地，座体161由石英石制成，石英石为透明件且耐高温，不会因为气溶胶生成基质温度较高而受损。
上述任一实施例中，加热器件100还包括测温引线70，测温引线70一端伸入隔热腔11与感应体52电连接，测温引线70另一端伸出隔热腔11与控制电路电连接，以通过测温引线70方便地检测感应体52的温度，以精准地控制感应体52的温度。
本实用新型一实施例中，还提供一种电子雾化装置，包括上述加热器件100，可以充分发挥红外加热的优势，使气溶胶生成基质在初始阶段快速升温，缩短预热时间。并且，红外辐射件50隔热装配，基座10不会接收到红外辐射件50的高温而使气溶胶生成基质烤焦，保证雾化口感。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
