然而现有的陶瓷发热体上的发热元件为印刷电子浆料烧结形成在多孔陶瓷体的雾化面上，实为发热线路，其在陶瓷发热体雾化面上的热场分布很不均匀，导致陶瓷发热体雾化面上有些区域温度过高，易使该区域的烟油因过热而产生焦味或有害物质，而有些区域的温度又较低，无法让该区域烟液被有效雾化。
对于电子烟雾化器而言，雾化器的加热线路设计影响了烟油雾化效果，线路排布需要满足烟雾浓度、加热温度的要求，从而实现口感需求。目前市场上的雾化器的加热线路多采用串联加热线路，加热均匀性受到限制。现有的S形或螺旋形加热丝在中心区容易存在局部温度偏高的问题。

本申请是发明人基于以下事实作出的发明创造。
图1显示了现有技术中的一种雾化器的加热组件。
如图1所示，现有技术中的加热线路为一条S型线路1，在装配时，将线路1串联在正极2和负极3之间。这样的设计不仅存在使中心区局部 温度偏高的问题，而且线路中一旦某一部分断路损毁，会导致整条线路无法使用，需要重新替换新的线路，导致整体维修费用提升。
基于此，本申请的发明人经过长期的创造性劳动，得出以下发明创造。
下面结合附图对根据本申请实施例的雾化器的加热组件100进行详细说明。
如图2和图3所示，根据本申请实施例的雾化器的加热组件100包括：载体10、正电极20、负电极30和加热线路40。加热线路40包括：多个第一加热段41、多个第二加热段42和加热板43。
具体而言，载体10为绝缘件，正电极20和负电极30彼此间隔地分布于载体10，加热线路40设于载体10。多个第一加热段41沿载体10的宽度方向并列设置，每个第一加热段41的第一端与正电极20连接。多个第二加热段42沿载体10的宽度方向并列设置，每个第二加热段42的第一端与负电极30连接。加热板43设于第一加热段41和第二加热段42之间，各个第一加热段41的第二端与加热板43的第一侧连接，各个第二加热段42的第二端与加热板43的第二侧连接，第一侧和第二侧彼此相反。所述加热板43的宽度大于第一加热段41和第二加热段42的宽度。其中，加热板的宽度指的是其宽度方向上的尺寸最小的宽度，并且加热段的宽度指的是其宽度方向上的尺寸最小的宽度。
换言之，根据本申请实施例的雾化器的加热组件100主要由能够起到承载作用的载体10、间隔开设置于载体10上的正电极20和负电极30、分别与正电极20和负电极30电连接的加热线路40组成。其中，载体10为绝缘体，例如可以为陶瓷件或玻璃件，其形状可以如图2或图3所示，也可以为其他形状，如长方体、圆柱体或其他不规则形状，在此不作限定。在装配时，可以将正电极20、负电极30和加热线路40安装在载体10上。
为了便于描述，将加热线路40与正电极20连接的一端定义为左端，将加热线路40与负电极30连接的一端定义为右端。也就是说，在安装时，可以将加热线路40的左端与正电极20电连接，并将加热线路40的右端与负电极30电连接，从而形成通路，使得加热线路40发热产生热量，进而对烟油进行加热雾化。
需要说明的是，如图2和图3所示，加热线路40主要由多个第一加热段41、多个第二加热段42和加热板43组成。其中，每个第一加热段41的左端均与正电极20连接，每个第一加热段41的右端与加热板43的第一侧连接。每个第二加热段42的左端与加热板43的第二侧连接，每个第二加热段42的右端与负电极30连接。也就是说，多个第一加热段41彼此并联，多个第二加热段42彼此并联，加热板43能够将并联的多个第一加热段41和并联的多个第二加热段43串联连接，起到连接第一加热段41和第二加热段42的作用。
为了便于描述，将载体10的长度方向定义为如图2所示的左右方向，并将载体10的宽度方向定义为如图2所示的上下方向。正电极20设置在载体10的左侧，负电极30设置在载体10的右侧，加热板43可设置在正电极20和负电极30的中间位置。第一加热段41的第一端(即，左端)与正电极20连接，第一加热段41的第二端(即，右端)与加热板43的第一侧(即，左侧)连接，第一加热段41从左向右延伸。也就是说，将第一加热段41的长度方向定义为左右方向，将第一加热段41宽度方向定义为上下方向。同理，将第二加热段42的长度方向定义为如图2所示的左右方向，将第二加热段42的宽度方向定义为如图2所示的上下方向。因此，所述第一加热段的宽度为第一加热段沿上下方向的宽度尺寸，所述第二加热段的宽度为第二加热段沿上下方向的宽度尺寸。如图2中所示，加热板43沿上下方向延伸，加热板43的宽度方向为左右方向，加热板43的长度方向为上下方向，所述加热板宽度为加热板沿左右方向的宽度尺寸。通过加大加热板43的宽度，能够减小加热板43的阻值，从而减少加热板43产生的热量。
由此，根据本申请实施例的雾化器的加热组件100，通过将载体10、正电极20、负电极30和加热线路40相结合，并且加热线路40主要由第一加热段41、第二加热段42和加热板43组成，通过采用串并联相结合的方式，使加热线路40在载体10上分布地更均匀，从而确保发热区域分布均匀，进而可以满足雾化器对烟油加热的均匀性要求。
根据本申请的一个实施例，雾化器的加热组件100包括：三个第一加 热段41和三个第二加热段42。在三个第一加热段41中，在所述载体的宽度方向上，位于中间位置的第一加热段为第一中间段411，位于第一中间段411两侧的第一加热段41分别为第一边缘段412和第二边缘段413，第一边缘段412与第二边缘段413相同或不同。在三个第二加热段42中，在所述载体的宽度方向上，位于中间位置的第二加热段42为第二中间段421，位于第二中间段421两侧的第二加热段42为第三边缘段422和第四边缘段423，第三边缘段422与第四边缘段423相同或不同。
也就是说，在加热板43的左侧可以分别设置有三个第一加热段41，在加热板43的右侧(即，第二侧)可以分别设置有三个第二加热段42，每个第一加热段41的左端可以与正电极20连接，每个第一加热段41的右端可以与加热板43的左侧连接；每个第二加热段42的左端可以与加热板43的右侧连接，每个第二加热段42的右端可以与负电极30连接。
此外，将三个第一加热段41分为一个第一中间段411、一个第一边缘段412和一个第二边缘段413，其中第二边缘段413可位于第一中间段411的下方，第一边缘段412可位于第一中间段411的上方。同样的，将三个第二加热段42分为一个第二中间段421、一个第三边缘段422和一个第四边缘段423，其中第四边缘段423可位于第二中间段421的下方，第三边缘段422可位于第二中间段421的上方。
可选地，第一边缘段412和第二边缘段413可以相对于第一中间段411对称设置。可选地，第三边缘段422和第四边缘段423可以相对于第二中间段421对称设置。可选地，第一加热段41和第二加热段42相对于加热板43对称设置。通过采用对称设置的方式，可以更好的保证加热线路40分布的均匀性。
可选地，第一中间段411和第二中间段421分别为直线形片段，第一边缘段412、第二边缘段412、第三边缘段422和第四边缘段423分别为弧形片段，这样不仅能够保证载体10的中心位置和侧边同时发热，还能够在相同条件下使第一中间段411的阻值分别小于第一边缘段412和第二边缘段412的阻值，并且第二中间段421的阻值分别小于第三边缘段422和第四边缘段423的阻值。即，载体10的中间区域产生的热量小于载体10的 边缘区域产生的热量，从而可以有效避免烟油的中间区域受热过大而边缘区域受热较小的情况。
根据本申请的一个实施例，第一中间段411与第二中间段422位于同一条直线上。通过将第一中间段411和第二中间段422设置在一条直线上，不仅能够方便加工，而且能够实现更好地对称分布效果。
可选地，第一中间段411的宽度大于第一边缘段412和第二边缘段413的宽度，第二中间段421的宽度大于第三边缘段422和第四边缘段423的宽度。也就是说，通过限定第一中间段411、第一边缘段412和第二边缘段413的宽度尺寸关系，以及第二中间段421、第三边缘段422和第四边缘段423的宽度尺寸关系，能够使第一中间段411的阻值小于第一边缘段412和第二边缘段413的阻值，第二中间段421的阻值小于第三边缘段422和第四边缘段423的阻值，从而可以进一步地减少中间位置产生的热量。
在本申请的一些具体实施方式中，加热板43包括：中间连接段433，以及沿所述载体的宽度方向设于所述中间连接段两侧且与所述中间连接段连接的上连接段431和下连接段432。优选地，至少一个第一加热段41的第二端和至少一个第二加热段42的第二端与中间连接段433连接。上连接段431和下连接段432分别设于中间连接段433的两端，上连接段431的第一端和下连接段432的第一端分别与中间连接段433连接。至少一个第一加热段41的第二端和至少一个第二加热段42的第二端与上连接段431连接，至少一个第一加热段41的第二端和至少一个第二加热段42的第二端与下连接段432连接。
可选地，中间连接段433的宽度大于上连接段431和下连接段432的宽度。通过扩大中间连接段433的宽度，减小了中间连接段433对应的阻值，从而减少了中间连接段433产生的热量。
根据本申请的一个实施例，所述中间连接段433呈圆形或椭圆形。将中间连接段433设置为圆形或椭圆形，不仅是因为圆形或椭圆形具有良好的对称性，还因为圆形或椭圆形的面积更大，对应的阻值更小，从而中间连接段433产生的热量会更低。
在本申请的一些具体实施方式中，雾化器的加热组件100还包括接线 盘44，接线盘44设于负电极30(或正电极20)的外周并与负电极30(或正电极20)连接，第一加热段41或第二加热段42与接线盘44连接，接线盘44能够起到连接和接线的作用。可选地，接线盘44为方形片段。
根据本申请的一个实施例，第一加热段41的宽度范围为0.1mm～5mm，相邻两个第一加热段41之间的间距为0.2mm～5mm。加热板43沿长度方向的尺寸范围为0.2mm～10mm，加热板43沿宽度方向的尺寸范围为0.2mm～10mm。其中需要说明的是，加热板43的尺寸相对于第一加热段41和第二加热段42等而言，具有面积较大、电阻较小的特征，因此，加热板43能够起到连接的作用，并且发热量较小。目前根据功率密度来设计加热线路40的线长，加热线路40的长度范围在1mm～20mm，加热线路40与载体10的边缘之间的距离为0.2mm～5mm，加热线路40的厚度为0.01mm～1mm。需要说明的是，加热线路40的总长度为多个第一加热段41、多个第二加热段42和加热板43的长度的加和长度。
其中需要说明的是，雾化器存储烟油并将其加热雾化形成可吸食的气溶胶，由于烟油的粘度或成分含量不同，并且用户对于烟雾浓度的需求也不相同，因此往往一根电子烟会配备不同的效果的雾化器。在需要实现烟雾浓度的不同时，往往需要改变加热组件产生的热量，也就是通过改变加热线路40的阻值以实现目的。
因此，可以通过调整第一加热段41、第二加热段42等的宽度范围等参数来调整相应的阻值，从而改变产生的热量。
此外，加热线路40与载体10的边缘之间的距离越大，加热线路40越居中，加热的范围越小，载体10的中心区域的温度也就越高。而加热线路40的总长度越长，加热范围越大，加热区域的分布也就越大。加热线路40的总电阻也可以通过改变其厚度进行调整，具体地，加热线路40的厚度越厚，总电阻越小，产生的热量也就越少，从而使产生的烟雾量也就越小。也就是说，加热线路40的总电阻可以通过改变加热线路40的厚度进行调整，其功率可以通过控制线路板进行调整，以使烟油雾化效果更稳定。
总而言之，根据本申请实施例的雾化器的加热组件100，通过将载体10、正电极20、负电极30和加热线路40相结合，并且在加热线路40中 将第一加热段41、第二加热段42和加热板43实行串并联相结合的电连接方式，确保了加热区域分布的均匀性，使得油烟受热均匀，不仅有效地防止了局部热点的出现，大大减小了产生焦味的可能性，使得烟雾效果良好，还能有效地进行热量传导，防止因升温过快而使雾化器的寿命衰减。
根据本申请实施例还提供了一种雾化器，该雾化器包括上述任一实施例的加热组件。由于根据本申请实施例的雾化器的加热组件100具有上述技术效果，因此，根据本申请实施例的雾化器也具有上述技术效果。最终可以实现雾化器对烟油加热的均匀性，确保烟量需求。
根据本申请实施例的雾化器的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
虽然已经通过例子对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
