请参阅图1和图2，本申请实施例提供了一种发热体100，发热体100为平板片状结构，包括发热部10以及沿发热部10横向两端延伸形成的导电部20，发热部10在位于纵向的两侧分别连接有至少一个固定部13，固定部13的横截面积大于发热部10中发热段横截面积的至少10%，例如，为50%，以确保发热体100在通电发热时，只发热部10发热，而固定部13不发热或只产生少量的热量。
在实际应用时，发热体100组装到雾化器的雾化组件中，贴合或嵌设于雾化组件中导油体的雾化面上，导电部20与雾化器的电极接触电连接，从而通过电极与供电电源和控制电路电连接，由控制电路控制供电电源为发热体100进行供电，以使发热体100的发热部10对导油体中吸收的雾化液进行加热雾化，以产生可供使用者吸食的气溶胶。
具体地，固定部13、发热部10和导电部20基本齐平（即厚度相同且处于同一平面），固定部13的宽度大于发热部10中发热段的宽度，例如固定部13的宽度在0.15mm和2mm之间，例如，为1.5mm；在发热体100组装到雾化器中时，通过导油体与支撑体300上下方向夹持固定发热体100以形成发热组件，该发热组件安装在雾化底座200的顶端，支撑体300对应发热部10的位置开设有与雾化底座200顶端雾化腔201连通的通道，此时支撑体300对导电部20和固定部13进行支撑，利用固定部13来为发热部10提供足够的支撑强度，使发热部10不易变形而完全贴设于导油体上，并保持发热部10平整，以确保发热部10与导油体不分离。
需要说明的是，若固定部13的宽度小于0.15mm，则发热体100在通电发热时，固定部13也产生热量变成发热区域，会导致发热部10的整体发热区域变大，发热体100所产生的热量分散到导电部20上，热量不集中造成雾化效果低，影响雾化所产生气溶胶的口感。
若固定部13的宽度大于2mm，则发热体100在通电发热时，虽然此时固定部13的阻值低，无法发热，但是由于其与发热部10的连接面积过大，造成发热部10所产生的热量向固定部13传导，同样存在热量不集中造成雾化效果低问题，影响雾化所产生气溶胶的口感。
在其他实施例中，固定部13也可沿竖向的其中一侧突出于发热部10和导电部20所在平面，且突出的高度小于1mm；也就是说，固定部13与发热部10的高度差低于1mm，且固定部13的突出方向为远离导油体方向，从而当发热体100夹持在导油体和支撑体300之间时，使发热部10更加贴合到导油体的雾化面上。
两侧固定部13的末端可凸出支撑体300的边缘，通过将凸出部分向支撑体300方向弯折而夹持卡紧到支撑体300的两侧，以支撑和更好地固定发热体100，使发热部10不易变形和位移。
在本实施例中，导电部20的横截面积由靠近发热部10的一端向另一端逐渐增大延伸，且导电部20的最小横截面积大于发热部10中发热段的横截面积，即导电部20的最小宽度d2大于发热部10中发热段的宽度d1。通过如此结构，可在保证导电部20对发热部10有足够支撑强度的同时，使得发热体100在通电发热时，导电部20发热量少，且由于导电部20与发热部10连接的一端为较小端，因此减少了发热部10的热量向导电部20方向的传导，使产生的热量集中于发热部10区域，雾化效果更好，并提高了热量利用效率。
其中，为方便导电部20与电极的接触连接，导电部20远离发热部10的一端为圆弧状，从而形成与所接触电极大小适配的圆形接触区域21，如此保证了导电部20与电极接触面积以及发热体100的整体强度。导电部20于接触区域21之外的位置可开设有至少一个镂空孔，以进一步地减少发热部10向导电部20方向传导热量。
导电部20远离发热部10的一端还延伸形成有一延伸部30，延伸部30的横截面积小于导电部20的最小横截面积，即延伸部30的宽度d3小于导电部20的最小宽度d2，从而在发热体100通电发热时，延伸部30不发热。
本实施例发热体100是由金属片通过蚀刻方式形成的一个整体，例如采用镍片、镍铬片、铁铬铝片、不锈钢片、金属钛片或合金片等导电金属件，其材料可根据实际情况进行选择，发热体100的厚度为0.05-0.2mm，例如，为0.1mm。发热体100的发热部10可以是各种发热较为均匀的形状，例如网格状、条纹状、S形、折线形、波浪形、锯齿形、螺旋形、圆形或矩形。
结合图3所示，本申请发热体100在实际制造时，选用一整块大尺寸的金属片，将金属片划分为蚀刻区101，由蚀刻区101围成并与发热体100相对应的成型区、围绕各成型区和蚀刻区101的边框区102，当将蚀刻区101去除后，成型区所形成的各发热体100分别通过其两端的延伸部30与边框区102连接在一起，如此可实现自动化从金属片上切割下来获得多个发热体100，实现批量化生产。
具体地，边框区102对应各延伸部30位置形成有矩形或三角形的连接点103，延伸部30通过连接点103与边框区102连接一起，且延伸部30与连接点103之间的接触宽度为大于0.15mm或小于3mm，例如，为，如此减少了延伸部30上的切割痕迹，并且切割痕迹位于延伸部30上，使切割痕迹避开了与电极接触的接触区域21，保证了导电部20与电极稳定接触。
本实施例中发热部10沿横向划分为位于中部的第一发热区域A以及沿位于第一发热区域A两侧的第二发热区域B，第一发热区域A中相邻两个发热段之间的间距大于第二发热区域B中相邻两个发热段之间的间距。从而在发热体100通电发热时，可以使中部第一发热区域A的温度降低，使两侧第二发热区域B的温度升高，以减少发热部10的中部温度与两侧温度之间的温差，从而使得整个发热部10的温度更均匀；本实施例发热体100在应用于具有双进液通道的雾化器中时，两侧的第二发热区域B分别靠近或对应两个进液通道的下方，更利于对导油体内的雾化液进行加热雾化。
具体地，如图1所示，本实施例中发热部10为呈S形或连续S形弯曲的发热丝，包括若干第一发热段11，若干第一发热段11沿横向间隔设置，并基本沿纵向延伸，且相邻两个第一发热段11的一端通过第二发热段12连接在一起，另一端相互隔开，发热部10的两个自由端分别连接于两个导电部20。即第一发热区域A中相邻两个第一发热段11之间的间距为D1，第二发热区域B中相邻两个第一发热段11之间的间距为D2，D1大于D2。
如此，当发热体100通电发热时，发热部10的中间第一发热区域A中两第一发热段11的间距较大，减少了第一发热区域A单位面积所产生的热量，降低了第一发热区域A的温度；而两侧第二发热区域B中两第一发热段11的间距较小，增加了第二发热区域B单位面积所产生的热量，增加了第二发热区域B所产生的热量，提高了第二发热区域B的温度，从而减少了发热部10的中部温度与两侧温度之间的温差，使发热部10沿横向分布的温度更加均匀，提高发热体100的雾化效果，避免了因局部温度过高而导致糊芯情况的发生。
其中，第一发热段11和第二发热段12的横截面积可以相同，即两者的宽度为d1，并小于导电部20的最小宽度d2，以使得发热体100在通电发热时导电部20发热量少，且热传导小。
本实施例中各第一发热段11的横截面积可以由中部向纵向两端逐渐缩小延伸。也就是说，第一发热段11的中部宽度为H1，第一发热段11的两端宽度均为H2，H1大于H2，通过如此结构，在发热体100两端的导电部20加载电压不变的情况下，使第一发热段11的中心位置功率微调降低，而第一发热段11的两端位置功率微调升高，使发热部10沿纵向分布的温度更加均匀，配合各第一发热段11的间距设置，从而使整个发热部10的整体区域温度更加均匀。
在本实施例中，第二发热段12的宽度与第一发热段11两端的宽度H2相同，第二发热段12为中部沿纵向向外凸出的弧形状，以提高发热部10发热时的沿纵向方向的热量均匀分布；每一第二发热段12连接有一个固定部13，固定部13沿纵向延伸，以提高对发热部10的支撑强度。在其他实施例中，固定部13的数量也可根据情况需要进行选择，例如，在保证对发热部10支撑强度的同时，间隔一个第二发热段12设置一个固定部13。
图4为图1所示发热体100的替换实施例，本实施例发热体100与图1所示发热体100的主要区别在于：为了给发热部10提供足够的支撑强度，本实施例其中一部分固定部13沿靠近发热体100的一端倾斜延伸，另一部分固定部13沿靠近发热体100的另一端倾斜延伸。
结合图5所示，本实施例针对的是没有设置支撑体300结构的雾化器，即发热体100是直接安装在雾化底座200的顶端，由于雾化腔201的两侧需要贯穿以与雾化器的出气管连通，因此雾化底座200的顶面由雾化腔201分隔成左右两支撑面。具体的说，位于发热体100左半部分的固定部13向左边倾斜延伸，从而由雾化底座200的左支撑面支撑，位于发热体100右半边部分的固定部13向右倾斜延伸，从而由雾化底座200的右支撑面支撑，如此利用雾化底座200的顶面来对导电部20和固定部13进行支撑，以使发热部10完全贴设于导油体上，保持发热部10平整，以确保发热部10与导油体不分离。
请参阅图6所示，为本申请发热体100另一实施例的结构示意图，本实施例发热体100与图1所示发热体100的主要区别在于：发热部10为呈S形或连续S形弯曲的发热丝，包括若干第一发热段11，若干第一发热段11沿纵向间隔设置，并基本沿横向延伸，且相邻两个第一发热段11的一端通过第二发热段12连接在一起，另一端相互隔开，发热部10的两个自由端分别连接于两个导电部20；即沿纵向最外侧的第一发热段11远离与第二发热段12连接的末端与导电部20连接，第一发热段11与导电部20圆滑过渡。
第一发热段11和第二发热段12的横截面积相同，即第一发热段11和第二发热段12的宽度d1小于导电部20的最小宽度d2以及延伸部30的宽度d3，以使发热体100通电发热时导电部20发热量少而延伸部30不发热，使发热体100发热时所产生的热量集中在发热部10区域。
其中，第二发热段12为中部沿横向向外凸出的弧形状，以提高发热部10发热时的沿横向方向的热量均匀分布。
在本实施例中，第二发热段12上连接的固定部13可以沿纵向延伸，也可以是发热体100一侧的固定部13朝向左侧倾斜延伸，发热体100另一侧的固定部13朝向右侧倾斜延伸。
本实施例于导电部20与第一发热段11的连接处还延伸形成有一个固定部13，配合第二发热段12上的固定部13，可提高对发热部10的支撑强度和稳定性。
请参阅图7所示，为本申请发热体100又一实施例的结构示意图，本实施例发热体100中的发热部10包括若干矩形状的发热丝14，若干发热丝14沿横向间隔设置，并依次串联于两个导电部20之间；每一发热丝14包括两个沿纵向延伸并平行相对的第一发热段11，两个第一发热段11的两端分别通过第二发热段12对应连接；在本实施例中，第二发热段12为直线段，每个第二发热段12上连接有沿纵向延伸的固定部13。
具体地，第一发热区域A中发热丝14的两个第一发热段11之间的间距为D3，第二发热区域B中发热丝14的两个第一发热段11之间的间距为D4，D3大于D4；从而当发热体100通电发热时，由于第一发热区域A中发热丝14的两个第一发热段11间距较大，减少了第一发热区域A单位面积所产生的热量，降低了第一发热区域A的温度；而两侧第二发热区域B中发热丝14的两个第一发热段11的间距较小，增加了第二发热区域B单位面积所产生的热量，提高了第二发热区域B的温度，从而减少了发热部10的中部温度与两侧温度之间的温差，使发热部10沿横向分布的温度更加均匀。
其中，相邻两个发热丝14之间通过串联部15连接，且串联部15的两端分别连接于与相邻两个发热丝14中对应一侧第一发热段11的中部，即串联部15所在直线将若干发热丝14分隔成上下对称的两个部分，每一发热丝14的上下两个部分是并联结构，若干发热丝14是串联结构。另外，第一发热段11和第二发热段12之间圆滑过渡，有利于热量均匀分布，避免了尖角部位热量堆叠集中而引起炸油发生。
第一发热区域A中相邻两个发热丝14之间的间距大于第二发热区域B中相邻两个发热丝14之间的间距，即第一发热区域A中串联部15的长度为D5，第二发热区域B中串联部15的长度为D6，且D5大于D6，从而当发热体100通电发热时，进一步微调降低第一发热区域A的温度，微调提高第二发热区域B的温度，以使发热部10的中部温度趋于两侧温度，使发热部10沿横向分布的温度更加均匀。
在本实施例中，第一发热段11和第二发热段12的横截面积相同，即第一发热段11和第二发热段12的宽度d1小于导电部20的最小宽度d2，以使发热体100通电发热时导电部20发热量少，使发热体100发热时所产生的热量集中在发热部10区域。
需要说明的是，本实施例中各第一发热段11的横截面积也可采用渐变结构，即第一发热段11的宽度由中部向两端渐缩延伸，以使发热部10沿纵向分布的温度更加均匀。
第一发热区域A中串联部15的宽度可以设置成大于第二发热区域B中串联部15的宽度，从而进一步的降低了发热部10中心位置的温度，有利于发热部10的整体区域温度均匀。
请参阅图8所示，为本申请发热体100再一实施例的结构示意图，本实施例发热体100中发热部10包括若干菱形状的发热丝14，若干发热丝14沿横向依次串联于两个导电部20之间，每个发热丝14具有一菱形孔，第一发热区域A中发热丝14的菱形孔沿横向最大间距为D7，第二发热区域B中发热丝14的菱形孔沿横向最大间距为D8，D7大于D8。
当发热体100通电发热时，减少了第一发热区域A单位面积所产生的热量，降低了第一发热区域A的温度；而增加了第二发热区域B单位面积所产生的热量，提高了第二发热区域B的温度，从而减少了发热部10的中部温度与两侧温度之间的温差，使发热部10沿横向分布的温度更加均匀。
具体地，本实施例中发热丝14包括两个相互平行的第一发热段11和两个相互平行的第二发热段12，两个第一发热段11和两个第二发热段12共同组成菱形状的发热丝14。第一发热段11和第二发热段12的横截面积相同，即第一发热段11和第二发热段12的宽度为d1，并小于导电部20的最小宽度d2，以使发热体100通电发热时导电部20发热量少，使发热体100发热时所产生的热量集中在发热部10区域。
若干发热丝14的短轴方向沿横向设置，长轴方向沿纵向设置，且本实施例中若干发热丝14直接串联连接，任意相邻两个发热丝14之间的连接点均位于发热体100沿纵向的中心线上，以使发热丝14发热时的沿纵向方向的上下两部分热量相同，有利于热量均匀分布。当然，在其他实施例中，若干发热丝14也可以间隔设置并依次串联连接。
在本实施例中，每一发热丝14的长轴方向两端分别连接有一个固定部13，固定部13沿纵向延伸，也就是说，每一个固定部13与所连接的第一发热段11和第二发热段12形成一个Y型结构，从而提高了对发热部10的支撑强度。
本实施例中的第一发热段11和第二发热段12的横截面积也可采用渐变结构设置，即第一发热段11和第二发热段12的宽度由远离固定部13的一端向靠近固定部13方向依次渐缩延伸，从而降低发热部10在横向中心线位置的温度，以使发热部10沿纵向分布的温度更加均匀。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例的相关描述。
以上为对本申请所提供的技术方案的描述，对于本领域的技术人员，依据本申请实施例的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本申请的限制。
