附图说明
为了更清楚的说明本发明实施例中的技术方案，下面将对实施例描述中所需要的附图做简单的介绍：
图1是本发明的加热器的实施例一的结构示意图；
图2是本发明的加热器的实施例一的线路涂布结构示意图；
图3是本发明的加热器的实施例二的结构示意图；
图4是本发明的加热器的实施例二的线路涂布结构示意图。
具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据 以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
如图1、图2所示，本发明实施例一提出的加热器，包括用于加热烟草制品以生成气溶胶的加热元件1，在加热元件1上间隔设置有两个发热电阻体2，每一个发热电阻体2的两端分别连接电极部3，电极部3的自由端用于连接热源部。其中，电极部3的自由端连接热源部时，使得两个发热电阻体2能够先后或共同工作发热，并将热快速传递至加热元件1，使得加热元件1的整体加热速度提高且加热均匀性好。
进一步地，电极部3包括一个第一电极31和两个第二电极32。两个发热电阻体2的第一端通过电引线4共同连接第一电极31，两个发热电阻体2的第二端通过电引线4分别连接一个第二电极32。两个发热电阻体2的第一端共用第一电极31，能够提高结构的空间利用率。
进一步地，两个发热电阻体2间隔设置在加热元件1的第一端部和加热元件1的第二端部。其中，加热元件1的第一端部用于接触烟草制品的起始段，而加热元件1的第二端部用于接触烟草制品的中后段。
进一步地，发热电阻体2通过电极部3连接热源部时，发热电阻体2激活，发热电阻体2激活后工作于工作状态和休眠状态。
进一步地，位于加热元件1的第一端部和第二端部的发热电阻体2均激活。
进一步地，位于加热元件1的第一端部的发热电阻体2处于工作状态，而位于加热元件1的第二端部的发热电阻体2处于休眠状态；或位于加热元件1的第二端部的发热电阻体2处于工作状态，而位于加热元件1的第一端部的发热电阻体2处于休眠状态。具体的，位于加热元件1的第一端部的发热电阻体2处于工作状态，而此时位于加热元件1的第二端部的发热电阻体2处于休眠状态，即位于加热元件1的第二端部的发热电阻体2只是处于激活却不工作的状态(待命状态)。或者，位于加热元件1的第二端部的发热电阻体2处于工作状态，而此时位于加热元件1的第一端部的发热电阻体2处于休眠状态，即位于加热元件1的第一端部的发热电阻体2只是处于激活却不工作的状态(待命状态)。因此，可以根据实际需要，先激活位于加热元件1的第一端部的发热电阻 体2工作一段时间，然后激活位于加热元件1的第二端部的发热电阻体2工作。或，先激活位于加热元件1的第二端部的发热电阻体2工作一段时间，然后激活位于加热元件1的第一端部的发热电阻体2工作。例如，当加热元件1启动时，先激活位于加热元件1的第一端部的发热电阻体2工作一端时间例如30秒，使得加热元件1的第一端部充足预热并能够使气溶胶挥发，然后激活位于加热元件1的第二端部的发热电阻体2工作一段时间例如30秒，使得加热元件1的第二端部充足预热并能够开始使气溶胶挥发。通过先后激活加热元件1不同位置处的两个发热电阻体2，能够实现加热元件1的第一端部和第二端部先后受热，并使得位于加热元件1的第一端部和第二端部的发热电阻体2处于交替工作状态，即实现加热元件1的第一端部和第二端部交替受热，能够进一步提高加热元件1的整体加热速度和加热均匀性，灵活性好，简捷高效。
进一步地，位于加热元件1的第一端部和第二端部的发热电阻体2均处于工作状态。具体的，位于加热元件1的第一端部的发热电阻体2激活工作，位于加热元件1的第二端部的发热电阻体2也激活工作。或位于加热元件1的第二端部的发热电阻体2激活工作，位于加热元件1的第一端部的发热电阻体2也激活工作。通过激活加热元件1的第一端部和第二端部的两个发热电阻体2并使其共同工作，能够进一步提高加热元件1的受热速度和整体受热的均匀性。综上所述，位于加热元件1的某一区域的发热电阻体2激活工作时，位于加热元件1的另一区域的发热电阻体2可以处于工作状态，也可以处于休眠状态。而且，位于加热元件1的某一区域的发热电阻体2可以激活工作一段时间，也可以持续处于工作状态。位于加热元件1的某一区域的发热电阻体2和位于加热元件1的另一区域的发热电阻体2能够先后或同时工作。
进一步地，位于加热元件1的第一端部的发热电阻体2激活，而位于加热元件1的第二端部的发热电阻体2不激活；或位于加热元件1的第二端部的发热电阻体2激活，而位于加热元件1的第一端部的发热电阻体2不激活，使用方便，灵活性好。
进一步地，两个发热电阻体2分别连接温度控制传感器，用于实时监测发热体电阻2的温度值。
进一步地，温度控制传感器检测到位于加热元件1的第一端部的发热电阻 体2达到预热温度时，然后激活位于加热元件1的第二端部的发热电阻体2进行预热。或温度控制传感器检测到位于加热元件1的第二端部的发热电阻体2达到预热温度时，然后激活位于加热元件1的第一端部的发热电阻体2进行预热。通过温度控制传感器能够进一步提高加热元件1的受热速度和受热均匀性，且温控性好。
进一步地，两个发热电阻体2分别连接定时器，用于定时开启或关闭发热电阻体。
进一步地，定时器定时开启发热电阻体2时，使得发热电阻体2定时工作，并且在一段时间后提示烟草制品开始挥发气溶胶。或定时器定时关闭发热电阻体2时，使得发热电阻体2定时休眠。通过定时器能够精确控制发热电阻体2的工作时间或休眠时间。
进一步地，两个发热电阻体2分别涂敷、粘结或组合在加热元件1上。
进一步地，加热元件1采用热传导材料制成。
进一步地，加热元件1采用陶瓷材料制成。
进一步地，热源部为电源。
进一步地，加热元件为针式加热元件、椭圆柱形加热元件、锥形加热元件、圆柱形加热元件或棱柱形加热元件。
使用时，第一电极31和两个第二电极32分别接通电源时，位于加热元件1的第一端部的发热电阻体2和第二端部的发热电阻体2激活共同工作而发热，并将热传递至加热元件1，实现加热元件1的整体加热的均匀性。
在上述实施例一的基础上，如图3、图4所示，本发明实施例二提出的加热器，与实施例一的不同之处在于，电极部3包括两个第三电极33和两个第四电极34。其中，两个发热电阻体2的第一端通过电引线4分别连接一个第三电极33，两个发热电阻体2的第二端通过电引线4分别连接一个第四电极34，通过两个第三电极33和两个第四电极34，能够提高电路的可靠性。
使用时，位于加热元件1的第一端部的发热电阻体2通过第三电极33和第四电极34分别连接热源部时，使得位于加热元件1的第一端部的发热电阻体2 激活工作，实现加热元件1的一段时间的预热。然后将位于加热元件1的第二端部的发热电阻体2通过第三电极33和第四电极34分别连接热源部，使得位于加热元件1的第二端部的发热电阻体2激活工作，此时，位于加热元件1的第一端部的发热电阻体2可以处于工作状态也可以处于休眠状态。位于加热元件1的第二端部的发热电阻体2可以工作一段时间也可以处于持续工作状态。且位于加热元件1的第一端部和第二端部的发热电阻体2可以处于交替或同时工作状态。因此，在加热元件1的第一端部和第二端部分别设置有发热电阻体2，能够使得加热元件1的整体加热速度提高，加热均匀性更好。
在上述加热器的基础上，另一方面，本发明提出的电加热系统，包括加热器容纳部，加热器容纳部容纳有上述加热器，用于加热烟草制品以产生气溶胶。
在一个具体的实施例中，多个发热电阻体2通过电极部3连接热源部。加热器用于加热烟草制品以产生气溶胶。
在一个具体的实施例中，第一电极31连接热源部，且两个第二电极32均连接热源部时，使得位于加热元件1的第一端部和第二端部的发热电阻体2均激活。或第一电极31连接热源部，而位于加热元件1的第一端部或第二端部的发热电阻体2通过第二电极32连接热源部时，使得位于加热元件1的第一端部或第二端部的发热电阻体2激活。
在一个具体的实施例中，两个第三电极33均连接热源部，且两个第四电极34均连接热源部时，使得位于加热元件1的第一端部和第二端部的发热电阻体2均激活。或位于加热元件1的第一端部或第二端部的发热电阻体2通过第三电极33和第四电极34分别连接热源部时，使得位于加热元件1的第一端部或第二端部的发热电阻体2激活。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
