同时参阅图1和图2，本申请提供的一种加热器10用于对加热基质进行加热，以使加热基质雾化形成可供用户抽吸的气溶胶，加热基质可以为雾化介质载体20等气溶胶生成基质。
第一实施例
同时参阅图2、图3和图4，加热器10包括支撑组件100、加热组件200和隔热层(图未示)，支撑组件100与加热组件200相互连接。加热组件200包括基座210和加热片220，加热片220的一端为固定端而固定在基座210上，加热片220的另一端为自由端，该自由端可以穿刺在雾化介质载体20的内部。当加热片220将电能转化为热能时，雾化介质载体20吸收加热片220的热能而雾化形成气溶胶。
支撑组件100包括内支架110和外支架120，内支架110和外支架120两者均可以为柱形筒状结构，外支架120套设在内支架110外部，隔热层可 以附着在外支架120的外表面上，使得隔热层与用户直接接触。隔热层的黑度系数可以小于0.1，故隔热层具有良好的隔热性能。
同时参阅图4、图5和图6，内支架110具有顶端面151、外侧壁面152、底端面153、内侧壁面154和内底壁面155。顶端面151、底端面153和外侧壁面152三者形成内支架110的外表面，内底壁面155和内侧壁面154两者形成内支架110的内表面，内底壁面155可以为平面状，内侧壁面154也可以为圆柱面，内侧壁面154与内底壁面155的周边连接而环绕内底壁面155设置，内底壁面155沿水平方向延伸，内侧壁面154沿竖直方向延伸。内支架110上开设有敞口腔130，内侧壁面154与内底壁面155两者共同界定该敞口腔130的边界，也即内侧壁面154与内底壁面155共同围成该敞口腔130，雾化介质载体20收容在该敞口腔130内。顶端面151和底端面153两者也可以均为沿水平方向延伸的平面，顶端面151、底端面153和内底壁面155三者沿内支架110的轴向间隔设置，内底壁面155位于顶端面151和底端面153之间，顶端面151和内底壁面155两者朝上设置，底端面153朝下设置。使得底端面153靠近基座210，内底壁面155相较于底端面153更远离基座210，顶端面151与底端面相背且远离基座210。外侧壁面152同样为圆柱面，外侧壁面152的上端与顶端面151连接，外侧壁面152的下端与底端面153连接，外侧壁面152环绕内侧壁面154设置。
外侧壁面152上开设有螺旋形凹槽143，螺旋形凹槽143的数量可以为多个，例如为四个或三个等。四个螺旋形凹槽143的旋向可以相同，例如可以同时左旋或右旋。每个螺旋形凹槽143的上端贯穿内支架110的顶端面151，从而使得螺旋形凹槽143的上端形成进气口141；螺旋形凹槽143的下端贯穿内支架110的底端面153，从而使得螺旋形凹槽143的下端形成出气口142。当外支架120套设在内支架110上后，外支架120与外侧壁面152相抵接，使得螺旋形凹槽143被外支架120封盖而形成螺旋形通道140。从进气口141输入螺旋形通道140内的外界气体经出气口142输出，换言之，外界气体先从进气口141输入至螺旋形通道140之内，且最后从出气口142输出至螺旋 形通道140之外。
敞口腔130的端部贯穿内支架110的顶端面151而形成敞开口131，即敞开口131设置在该顶端面151上，雾化介质载体20可以通过该敞开口131插入至敞口腔130内，使得敞开口131对雾化介质载体20形成收容作用。加热片220的一部分收容在该敞口腔130内，当雾化介质载体20与敞口腔130配合时，加热片220可以穿刺至雾化介质载体20内部。螺旋形通道140的进气口141同样位于该顶端面151上，当螺旋形通道140的数量为多个时，多个进气口141环绕敞开口131设置，且多个进气口141沿内支架110的周向间隔设置，例如任意相邻两个进气口141所间隔的角度相等，即多个进气口141沿圆周方向均匀分布。鉴于螺旋形通道140的出气口142位于该底端面153，以整个支撑组件100的轴向为参考方向，此时，进气口141和出气口142两者之间的距离大于敞口腔130的长度。换言之，敞口腔130沿垂直于该参考方向的正投影全部落在该螺旋形通道140所覆盖的区域之内。很明显，进气口141相对出气口142更加靠近敞开口131。当然，进气口141也可以位于外侧壁面152上，即进气口141与敞开口131在参考方向上存在一定的距离，此时，进气口141和出气口142两者之间的距离可以小于敞口腔130的长度，使得敞口腔130沿垂直于该参考方向的正投影的一部分落在该螺旋形通道140所覆盖的区域之内，另一部分则落在该螺旋形通道140所覆盖的区域之外。总之，至少部分正投影位于螺旋形通道140所覆盖区域之内。
基座210和内支架110的底端面153之间还形成有导气通道161，内支架110上还开设有配合孔162，该配合孔162为通孔且贯穿内底壁面155和底端面153，使得配合孔162同时连通敞口腔130和导气通道161，加热片220穿过该配合孔162而使其一部分收容在敞口腔130之内。当用户抽吸雾化介质载体20时，外界气体从进气口141输入至螺旋形通道140内部并从出气口142输出至导气通道161中，然后从导气通道161经配合孔162进入至敞口腔130内，从而使得外界气体携带气溶胶被用户吸收，故外界气体依次经螺旋形通道140、导气通道161和配合孔162而进入至敞口腔130内以携 带气溶胶。
通过设置该螺旋形通道140，在用户抽吸和加热片220产生热量的过程中，当温度较低的外界气体流经该螺旋形通道140时，外界气体将吸收内支架110上的热量而重新从导气通道161和配合孔162流入至敞口腔130内，故外界气体可以对热量起到一定的回收作用。一方面使得外界气体回收的热量可以重新用于雾化介质载体20的加热，尽可能减少热量损失率，从而提高整个加热器10能量的利用率。另一方面可以减少敞口腔130传导至外支架120上的热量，减低外支架120上的温度，防止用户在握持整个支撑组件100时会产生灼热的不适感甚至烫伤。
假如螺旋形通道140采用直线型通道进行替换时，由于外界气体在直线型通道内的流动路径远小于在螺旋形通道140内的流动路径，使得外界气体无法在较短的流动路径吸收足够的热量进入敞口腔130内，即外界气体没有充足的时间进行热交换，导致热量的回收利用率不高。大部分热量仍然传导至支撑组件100的外表面，使得支撑组件100的外表面产生灼热的不适感。而该实施例采用螺旋形通道140，进气口141和出气口142之间的轴向距离大于敞口腔130的长度，使得螺旋形通道140中的外界气体能与内支架110上各部分向外传导的热量直接接触，同时，外界气体在螺旋形通道140内的流动路径较长，使得外界气体有足够的机会和时间尽可能回收较多的热量，从而进一步提高能量的利用率并防止支撑组件100产生灼热的不适感。
假如螺旋形通道140采用不规则通道进行替换时，外界气体在不规则通道中会产生涡旋和湍流(即紊流)，使得外界气体在该不规则通道中各处的流速不尽相同。外界气体在涡旋处流动较慢，在其他部位则流速相对较快，因此，当外界气体在该不规则通道中某处的速较快时，将使得外界气体于该处在较短之间内来不及吸收较多的热量，该处无法及时吸收的热量将直接传到至支撑组件100的外表面，继而使得支撑组件100外表面上与该不规则通道中气体流速较快之处所对应的位置将出现局部高温。而该实施例采用螺旋形通道140，外界气体在螺旋形通道140中各处的流速基本相同，有效防止外 界气体出现涡流等流动不畅的现象，当大部分热量被螺旋形通道140的外界气体回收至敞口腔130内时，能有效确保传导至支撑组件100上的热量均匀分布在支撑组件100的外表面，避免外表面出现局部高温而导致用户产生不适感。
同时，外支架120上附着有隔热层，该隔热层进一步阻止敞口腔130中的热量向外辐射，提高整个加热器10能量的利用率，并防止加热器10外表面温度过高。
第二实施例
同时参阅图7、图8和图9，该第二实施例的加热器10与第一实施例的加热器10的主要区别在于：螺旋形通道140直接开设在支撑组件100的内侧壁面154上，使得螺旋形通道140中外界气体所形成的气流能与雾化介质载体20直接接触。而对于第一实施例中的加热器10，显然，螺旋形通道140中外界气体所形成的气流无法与雾化介质载体20直接接触。
具体而言，加热器10包括支撑组件100、加热组件200和隔热层，支撑组件100与加热组件200相互连接。加热组件200包括基座210和加热片220，加热片220的一端为固定端而固定在基座210上，加热片220的另一端为自由端，该自由端可以穿刺在雾化介质载体20的内部。当加热片220将电能转化为热能时，雾化介质载体20吸收加热片220的热能而雾化形成气溶胶。
支撑组件100可以为柱形筒状结构，隔热层可以附着在支撑组件100的外表面上，使得隔热层与用户直接接触。隔热层的黑度系数可以小于0.1，故隔热层具有良好的隔热性能。
支撑组件100具有顶端面151、外侧壁面152、底端面153、内侧壁面154和内底壁面155。顶端面151、底端面153和外侧壁面152三者形成支撑组件100的外表面，内底壁面155和内侧壁面154两者形成支撑组件100的内表面，内底壁面155可以为平面状，内侧壁面154也可以为环状，内侧壁面154与内底壁面155的周边连接而环绕内底壁面155设置，内底壁面155沿水平方向延伸，内侧壁面154沿竖直方向延伸。支撑组件100上开设有敞口腔130， 内侧壁面154与内底壁面155两者共同界定该敞口腔130的边界，也即内侧壁面154与内底壁面155共同围成该敞口腔130，雾化介质载体20收容在该敞口腔130内。顶端面151和底端面153两者也可以均为沿水平方向延伸的平面，顶端面151、底端面153和内底壁面155三者沿支撑组件100的轴向间隔设置，内底壁面155位于顶端面151和底端面153之间，顶端面151和内底壁面155两者朝上设置，底端面153朝下设置。使得底端面153靠近基座210，内底壁面155相较于底端面153更远离基座210，顶端面151与底端面相背且远离基座210。外侧壁面152同样为环状，外侧壁面152的上端与顶端面151连接，外侧壁面152的下端与底端面153连接，外侧壁面152环绕内侧壁面154设置。
内侧壁面154上开设有螺旋形凹槽143，螺旋形凹槽143的数量可以为多个，例如为四个或三个等。四个螺旋形凹槽143的旋向可以相同，例如可以同时左旋或右旋。螺旋形凹槽143的上端贯穿支撑组件100的顶端面151，从而使得螺旋形凹槽143的上端形成进气口141；螺旋形凹槽143的下端延伸至内底壁面155，从而使得螺旋形凹槽143的下端形成出气口142。当雾化介质载体20收容在敞口腔130中时，雾化介质载体20与内侧壁面154相抵接，使得螺旋形凹槽143被雾化介质载体20封盖而形成螺旋形通道140。从进气口141输入螺旋形通道140内的外界气体经出气口142输出，换言之，外界气体先从进气口141输入至螺旋形通道140之内，且最后从出气口142输出至螺旋形通道140之外。
敞口腔130的端部贯穿支撑组件100的顶端面151而形成敞开口131，即敞开口131设置在该顶端面151上，雾化介质载体20可以通过该敞开口131插入至敞口腔130内，使得敞开口131对雾化介质载体20形成收容作用。加热片220的一部分收容在该敞口腔130内，当雾化介质载体20与敞口腔130配合时，加热片220可以穿刺至雾化介质载体20内部。螺旋形通道140的进气口141同样位于该顶端面151上，当螺旋形通道140的数量为多个时，多个进气口141沿支撑组件100的周向间隔设置，例如任意相邻两个进气口 141所间隔的角度相等，即多个进气口141沿圆周方向均匀分布。鉴于螺旋形通道140的下端延伸至内底壁面155而形成出气口142，以整个支撑组件100的轴向为参考方向，此时，进气口141和出气口142两者之间的距离等于敞口腔130的长度。换言之，敞口腔130沿垂直于该参考方向的正投影全部刚好落在该螺旋形通道140所覆盖的区域之内，即该正投影覆盖全部螺旋形通道140所在的区域。很明显，进气口141相对出气口142更加靠近敞开口131。当然，进气口141也可以位于外侧壁面152上，即进气口141与敞开口131在参考方向上存在一定的距离，此时，进气口141和出气口142两者之间的距离可以小于敞口腔130的长度，使得敞口腔130沿垂直于该参考方向的正投影的一部分落在该螺旋形通道140所覆盖的区域之内，另一部分则落在该螺旋形通道140所覆盖的区域之外。总之，至少部分正投影位于螺旋形通道140所覆盖区域之内。
支撑组件100还包括凸起部170，凸起部170设置在该内底壁面155上，凸起部170相对该内底壁面155凸出一定的高度，当雾化介质载体20的下端与凸起部170相抵接时，敞口腔130位于雾化介质载体20与内底壁面155之间的空间将形成导气通道161，换言之，雾化介质载体20和内底壁面155两者将敞口腔130的一部分围设形成导气通道161。支撑组件100上还开设有配合孔162，该配合孔162为通孔且同时贯穿内底壁面155和底端面153，使得配合孔162连通导气通道161，加热片220穿过该配合孔162而使其一部分收容在敞口腔130之内。当然，配合孔162可以被密封处理，使得导气通道161中的气体无法从配合孔162中流出。当用户抽吸雾化介质载体20时，外界气体从进气口141输入至螺旋形通道140内部并从出气口142输出至导气通道161中，从而使得外界气体携带气溶胶被用户吸收，故外界气体通过螺旋形通道140进入导气通道161以携带气溶胶。
通过设置该螺旋形通道140，在用户抽吸和加热片220产生热量的过程中，当温度较低的外界气体流经该螺旋形通道140时，外界气体将吸收支撑组件100上的热量而重新进入至导气通道161内，故外界气体可以对热量起 到一定的回收作用。一方面使得外界气体回收的热量可以重新用于雾化介质载体20的加热，尽可能减少热量损失率，从而提高整个加热器10能量的利用率。另一方面可以减少敞口腔130传导至支撑组件100上的热量，减低支撑组件100的温度，防止用户在握持整个支撑组件100时会产生灼热的不适感甚至烫伤。
假如螺旋形通道140采用直线型通道进行替换时，由于外界气体在直线型通道内的流动路径远小于在螺旋形通道140内的流动路径，使得外界气体无法在较短的流动路径吸收足够的热量进入敞口腔130内，即外界气体没有充足的时间进行热交换，导致热量的回收利用率不高。大部分热量仍然传导至支撑组件100的外表面，使得支撑组件100的外表面产生灼热的不适感。而该实施例采用螺旋形通道140，进气口141和出气口142之间的轴向距离等于敞口腔130的长度，使得螺旋通道中的外界气体能与支撑组件100上各部分向外传导的热量直接接触，同时，外界气体在螺旋形通道140内的流动路径较长，使得外界气体有足够的机会和时间尽可能回收较多的热量，从而进一步提高能量的利用率并防止支撑组件100产生灼热的不适感。
假如螺旋形通道140采用不规则通道进行替换时，外界气体在不规则通道中会产生涡旋和湍流(即紊流)，使得外界气体在该不规则通道中各处的流速不尽相同。外界气体在涡旋处流动较慢，在其他部位则流速相对较，因此，当外界气体在该不规则通道中某处的速较快时，将使得外界气体于该处在较短之间内来不及吸收较多的热量，该处无法及时吸收的热量将直接传到至支撑组件100的外表面，继而使得支撑组件100外表面上与该不规则通道中气体流速较快之处所对应的位置将出现局部高温。而该实施例采用螺旋形通道140，外界气体在螺旋形通道140中各处的流速基本相同，有效防止外界气体出现涡流等流动不畅的现象，当大部分热量被螺旋形通道140的外界气体回收至导气通道161内时，能有效确保传导到至支撑组件100上的热量均匀分布在支撑组件100的外表面，避免外表面出现局部高温而导致用户产生不适感。
同时，支撑组件100上附着有隔热层，该隔热层进一步阻止敞口腔130中的热量向外辐射，提高整个加热器10能量的利用率，并防止加热器10外表面温度过高。
本申请还提供一种电子雾化装置，该电子雾化装置包括电源组件和加热器10，加热器10与电源组件可拆卸连接，电源组件对加热器10中的加热片220供电。
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。
