优选的实施中，红外电热涂层112形成在基体111的外表面上。自基体111的近端朝向基体111的远端方向，即沿基体111的轴向方向， 红外电热涂层112包括间隔设置的第一红外电热涂层S1、第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)。第二红外电热涂层(S21、S22)包括沿基体111的周向方向间隔设置的红外电热涂层S21和红外电热涂层S22(子红外电热涂层)，第三红外电热涂层(S31、S32)包括沿基体111的周向方向间隔设置的红外电热涂层S31和红外电热涂层S32，第四红外电热涂层(S41、S42)包括沿基体111的周向方向间隔设置的红外电热涂层S41和红外电热涂层S42。

电极114a与第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)间隔设置。沿基体111周向方向，电极114a与电极113a是间隔设置的，即设置在红外电热涂层S21、S31、S41的两侧。电极114a的轴向延伸长度小于电极113a的轴向延伸长度。电极114a的一端靠近第一红外电热涂层S1设置，优选的，电极114a的一端与第一红外电热涂层S1保持接触；电极114a的另一端靠近基体111的远端设置。
电极114b设置在第一红外电热涂层S1与第二红外电热涂层(S21、S22)之间，或者设置在电极113b与电极113c之间。电极114b始于电极114a，一部分电极114b沿基体111的第一周向方向，例如顺时针方向延伸之后靠近电极113a设置，该一部分电极114b与红外电热涂层S1和红外电热涂层S21保持接触以形成电连接；另一部分电极114b沿基体111的第二周向方向，例如逆时针方向延伸之后靠近电极113a设置，该另一部分电极114b与红外电热涂层S1和红外电热涂层S22保持接触以形成电连接。
电极114c设置在第三红外电热涂层(S31、S32)与第四红外电热涂层(S41、S42)之间。电极114c始于电极114a，一部分电极114c沿基体111的第一周向方向，例如顺时针方向延伸之后靠近电极113a设置，该一部分电极114c与红外电热涂层S31和红外电热涂层S41保持接触以形成电连接；另一部分电极114c沿基体111的第二周向方向，例如逆时针方向延伸之后靠近电极113a设置，该另一部分电极114c与红外电热涂层S32和红外电热涂层S42保持接触以形成电连接。
在电极113和电极114导电之后，电极113和电极114将电芯7提供的电功率同时馈送至第一红外电热涂层S1、第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)。即，第一红外电热涂层S1、第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)相当 于是并联连接在电极113和电极114之间的。红外电热涂层S21和红外电热涂层S22、红外电热涂层S31和红外电热涂层S32、红外电热涂层S41和红外电热涂层S42也是并联连接在电极113和电极114之间的。通过多个并联的红外电热涂层，整体上可降低红外电热涂层112的阻值。假设电流从电极113流入，从电极114流出，则红外电热涂层112上的电流流向基本上是沿基体111的轴向方向延伸的(如图中的虚线箭头所示)。其中，第一红外电热涂层S1、第三红外电热涂层(S31、S32)上的电流流向与从基体111近端朝向基体111远端的延伸方向是一致的，而第二红外电热涂层(S21、S22)、第四红外电热涂层(S41、S42)上的电流流向与从基体111远端朝向基体111近端的延伸方向是一致的，相邻的红外电热涂层上的电流流向是相反的。
可以理解的，多个并联的红外电热涂层，其数量并不限于图3-图4所示的，可以增加或者减少。
在多个并联的红外电热涂层中，每一个红外电热涂层的等效电阻可以都相同，也可以部分相同，还可以都不相同；与此类似的，每一个红外电热涂层的加热功率可以都相同，也可以部分相同，还可以都不相同。通过调节每一个红外电热涂层的等效阻值，可以调节每个区域的功率分布，从而调节每个区域的温度分布。
优选的实施中，第一红外电热涂层S1的等效阻值相对的较小，其加热功率相对的要大些，加热速度相对的要快些；这样，第一红外电热涂层S1对应的部分气溶胶形成基质，相对于其它红外电热涂层对应的部分气溶胶形成基质来说，其温度可以快速上升并产生可抽吸的气溶胶，进而缩短了气溶胶形成基质的预热时间，减少了抽吸等待时间。第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)的等效阻值可以相同。
需要说明的是，第一红外电热涂层S1的加热速度相对于其它红外电热涂层，例如第二红外电热涂层(S21、S22)的加热速度的要更快，可以通过以下方式来验证：设置同一个预设温度，当第一红外电热涂层S1的加热温度从初始温度(例如环境温度)达到预设温度时，如果第二红外电热涂层(S21、S22)的加热温度是低于预设温度的，则可以说明第一红外电热涂层S1的加热速度相对于第二红外电热涂层(S21、S22)的加热速度的要更快。预设温度可以为气溶胶生成装置100的最大温度，也可以为工作温度，即能够使得气溶胶形成基质产生气溶胶的温度。
由于等效阻值、加热功率或者加热速度的不同，在气溶胶生成装置100的预热阶段，不同红外电热涂层之间的温度存在差异或者差异较大； 而在气溶胶生成装置100的保温阶段或者抽吸阶段，不同红外电热涂层之间的温度差异相对较小。上述预热阶段、保温阶段或者抽吸阶段，是气溶胶形成制品或者红外电热涂层的温度随时间变化的曲线中的不同持续时间段。
需要说明的是，依据电阻的计算公式R＝ρL/S，在电阻率ρ一定时(红外电热涂层涂覆均匀时，其电阻率ρ是一定的)，电阻的阻值取决于参数L、S的值。因此，通过红外电热涂层的L、S两个参数的设置，可以调节每一个红外电热涂层的等效阻值。
需要说明的是，在图3-图4的示例中，电极113和电极114的布置，利于与电芯7之间的走线，例如：与电极113电连接的第一导线、与电极114电连接的第二导线，第一导线和第二导线的一端都可以设置在基体111的远端，第一导线和第二导线的另一端与电芯7电连接。当然，第一导线的一端设置在基体111的远端，而第二导线的一端设置在基体111的近端，也是可行的。
需要说明的是，在图3-图4的示例中，基体111上还设置有定位槽，优先的实施中，该定位槽设置在基体111远端的端部，例如由基体111远端的部分端部凹陷形成。定位槽可用于对基体111进行定位，例如：在装配时，基座13上的凸块与该定位槽配合，以保持基体111的远端；在制造加热器11时，制备工具通过与该定位槽配合，可确定涂覆电加热膜层、电极的方位、终点等信息，即利于电加热膜层、电极的涂覆，提升制造效率。
需要说明的是，电极113a与红外电热涂层112间隔设置，电极114a与第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)间隔设置，可以通过以下至少之一来实现：
先在基体111的表面上涂覆导电元件；然后在基体111的表面上涂覆电加热膜层；最后在涂覆的所述电加热膜层中，去除掉靠近电极113a和电极114a的部分电加热膜层；
先在基体111的表面上涂覆电加热膜层，然后在基体111的表面上涂覆导电元件，最后去除掉靠近电极113a和电极114a的部分电加热膜层；
先在基体111的表面上涂覆电加热膜层，然后去除掉部分表面上的电加热膜层，最后在该部分表面上部分涂覆导电元件；(部分涂覆指的是导电元件或者电加热膜层未涂满对应的表面，以下类似)
在基体111的第一部分表面上部分涂覆导电元件，在基体111的第 二部分表面上全部涂覆电加热膜层；或者，在基体111的第一部分表面上全部涂覆导电元件，在基体111的第二部分表面上部分涂覆电加热膜层；或者，在基体111的第一部分表面上部分涂覆导电元件，在基体111的第二部分表面上部分涂覆电加热膜层；(全部涂覆指的是导电元件或者电加热膜层涂满对应的表面)
在基体111的第一部分表面上涂覆导电元件，在基体111的第二部分表面上涂覆电加热膜层，所述第一部分表面与所述第二部分表面是间隔设置的。
为了便于理解，以下结合其中一种间隔设置方式对图3-图4示例中的加热器11的制作方法进行说明：
如图5所示，加热器11的制作方法包括：
步骤S11、提供基体111，并在基体111的表面上涂覆红外电热涂层和导电元件；
在该步骤中，可以先涂覆红外电热涂层，再涂覆导电元件；也可以先涂覆导电元件，再涂覆红外电热涂层。导电元件的形状按照图3-图4示例进行涂覆，红外电热涂层沿基体111的周向方向涂覆一周，红外电热涂层的上下两端与基体111的端部保持间隔。
步骤S12、在涂覆的所述红外电热涂层中，去除掉靠近电极113a和电极114a的部分红外电热涂层。
在该步骤中，需要在涂覆的红外电热涂层中，去除掉靠近电极113a和电极114a的部分红外电热涂层，从而形成图3或者图4所示的第一红外电热涂层S1、第二红外电热涂层(S21、S22)、第三红外电热涂层(S31、S32)以及第四红外电热涂层(S41、S42)。
图6-图7是本申请第二示例提供的一种加热器。
在图6-图7的示例中，红外电热涂层112包括第一红外电热涂层S1。第一红外电热涂层S1没有分隔成其它红外电热涂层。
电极113包括沿基体111的轴向方向延伸且呈条形状的电极113a，沿基体111的周向方向延伸且呈弧形状的电极113b。
与图3-图4示例类似的，电极113a与第一红外电热涂层S1间隔设置；电极113a的一端靠近基体111的近端设置，电极113a的另一端靠近基体111的远端设置。电极113b靠近基体111的近端设置；电极113b始于电极113a，沿基体111的周向方向延伸之后终止于电极113a；电极113b的周向延伸长度大于第一红外电热涂层S1的周向延伸长度；电极113b与第一红外电热涂层S1保持接触以形成电连接。
与图3-图4示例不同的是，电极114被构造成沿基体111的周向方 向延伸且呈弧形状。电极114靠近基体111的远端设置。电极114的周向延伸长度与第一红外电热涂层S1的周向延伸长度相同。电极114与第一红外电热涂层S1保持接触以形成电连接。
与图3-图4示例不同的是，基体111的内径介于6mm～15mm，或介于7mm～15mm，或介于7mm～14mm，或介于7mm～12mm，或介于7mm～10mm。基体111的轴向延伸长度介于15mm～30mm，或介于15mm～28mm，或介于15mm～25mm，或介于16mm～25mm，或介于18mm～25mm，或介于18mm～24mm，或介于18mm～22mm。该尺寸的基体111适用于粗短型的气溶胶生成制品。
从电阻的计算公式R＝ρL/S来看，电流流向基本上是沿基体111的轴向方向延伸的红外电热涂层112，相对于电流流向基本上是沿基体111的周向方向延伸的红外电热涂层来说，参数L的值是减小的、而参数S的值是增大的；因此，图6-图7示例的加热器能够降低红外电热涂层112的阻值。如果像图3-图4示例一样，将多个红外电热涂层并联连接，则可进一步地降低红外电热涂层112的阻值。
与图3-图4示例类似的，电极113和电极114的布置，利于与电芯7之间的走线。
