技术领域
本申请涉及电子雾化技术领域，特别涉及一种雾化芯、雾化器及电子雾化装置。
背景技术
电子烟以及用于雾化非尼古丁介质(如保健药物、治疗药物等)的电子设备可统称电子雾化装置。雾化芯作为电子雾化装置的核心部件，一直是本领域技术人员研究的重点，目前市面上的雾化芯主要由导液体和发热体组成，其一般是采用在导液体内埋入发热电阻的方式，或者采用厚膜印刷的制作工艺制作而成。即，将发热体平铺在导液体之上，或者将发热体覆盖在导液体之上。
此类型的雾化芯普遍存在的缺点是：发热电阻工作时其周围温度会迅速升高以将周围的雾化液加热并雾化，发热电阻所产生的大量热量会对其周边产生压力，该压力会将从导液体流向发热电阻的雾化液推向远离发热电阻的方向，只有在发热电阻停止工作后，雾化液才会从导液体流到发热电阻周围。而一旦发热电阻再次开始工作，因发热电阻发热产生的热量又会产生压力，将雾化液推向远离发热电阻的方向，从而形成了脉冲式的进液方式。这样很容易导致雾化芯持续使用时间过长，而面临因发热电阻周围欠液而产生干烧的危险，并且会影响使用者的吸食口感。

有益效果
在本申请的技术方案中，一方面通过采用金属毛毡材料或者多孔导电陶瓷材料制成发热体，使得发热体可成为兼具导液和发热功能的多孔导电发热结构，进而使得雾化液可由导液体流入发热体的孔隙中，发热体整体能够由内而外地对渗入到发热体中的雾化液以及发热体表面的雾化液全面充分地进行雾化，提升了使用者的吸食口感，能够更好地满足喜好吸食大烟雾的使用者的需求；另一方面通过将发热体设计为包括连接部和发热部这两部分的结构，并将连接部嵌入导液体的通道内侧壁以及将发热部裸露于导液体的通道中，如此可减少发热体中作为高温部分的发热部与导液体的接触面积，避免发热体与导液体之间的高温面积过大，雾化液雾化为汽态烟雾后因烟雾体积膨胀(或者是因雾化液雾化为汽态烟雾之前因过多的雾化液温度升高而产生较大的压强)而对发热体的周边产生过大的压力，进而可避免在该压力的作用下迫使导液体中的雾化液沿远离发热体的方向流动，解决了脉冲式流入雾化液的技术问题；如此，在发热体进行发热的过程中，当发热部所含有的雾化液被加热并雾化时，发热体中的雾化液含量减少，使得发热体中的液体压强小于导液体中的液体压强而形成负压，进而使得雾化液可顺畅地从导液体中流入到发热体中进行补充，从而使得发热体在发热过程中能够在导液体的通道内持续性地产生充分的烟雾并能保障所产生的烟雾能够被通道中的气流带走，以供用户使用，因此有效降低了当持续使用时间过长时雾化芯会发生缺液干烧的风险，而且由于发热体能够持续性地产生充分的烟雾，因此可有效提升使用者的吸食口感。
此外，与传统利用发热体产生的热量对导液体中的雾化液进行加热雾化的雾化芯相比，本申请技术方案所提供的雾化芯可使得雾化液由导液体流入至发热体中进行雾化，从而在发热体发热过程中，可充分利用发热部表面和内部所产生的热量共同来对发热部中所存储的雾化液进行雾化，而不只是局限于发热体表面热量的利用，因此有效提高了热量的利用率，使得雾化芯可实现小功率出雾的效果。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，若本申请实施例中有涉及方向性指示(诸如上、下、左、右、前、后……)，则该方向性指示仅用于解释在某一特定姿态下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。

参照图1-24，本申请实施例提供一种雾化芯10，该雾化芯10包括导液体1和至少一个发热体2，其中：
导液体1围合设置而形成中空贯通的通道11，该通道11可供气体和烟雾流过；
发热体2由金属毛毡或者多孔导电陶瓷制成，发热体2包括连接部21以及与连接部21相连接的发热部22，连接部21嵌设于通道11的内侧壁上，发热部22外露于通道11的内侧壁设置。
在本实施例中，具体地，导液体1可以是导油棉、玻璃纤维体、发泡金属(如发泡镍)、多孔陶瓷体等导液材料，只要能够用于传导雾化液即可，本实施例对此不作具体的限制。其中，多孔陶瓷体是一种经高温烧结、体内具有大量彼此相通并与材料表面也相贯通的孔隙结 构的多孔陶瓷材料，而且由于多孔陶瓷体本身即便发生偶尔干烧也不会产生有害物质，因此相对于导油棉而言，会更加环保和安全。此外，更为具体地，当导液体1为多孔陶瓷体时，多孔陶瓷体的材料可以是氧化铝、碳化硅、氧化硅中的其中一种或任意两种以上的混合物，当然也可以是其他材料，只要能满足使用要求即可，本实施例对此不作具体的限制。
在本实施例中，具体地，本实施例的发热体2可以由金属毛毡材料制成，也可以由多孔导电陶瓷材料制成，即本实施例的发热体2可以是金属毛毡发热体，也可以是多孔导电陶瓷发热体。其中，可以理解的是，金属毛毡又叫多孔金属纤维毡，是一种由单一金属(如铜、铝等)或者多种金属的合金(如不锈钢等)做成的微米级甚至是纳米级细丝经过压实后所得的多孔材料，其体内具有大量彼此相通并与材料表面也相贯通的孔隙结构，且其厚度、孔隙度以及电阻大小均可根据需要进行控制，当然，本实施例的金属毛毡发热体也可以采用本领域已成熟的其它工艺来制作，如高温烧结工艺，只要能满足使用要求即可，本实施例对此不作具体的限制。此外，可以理解的是，多孔导电陶瓷是一种体内具有大量彼此相通并与材料表面也相贯通的孔隙结构的可导电陶瓷材料，本实施例的多孔导电陶瓷发热体具体可通过粉末原料高温烧结而成，其中，粉末原料可以包含碳化硅、氧化硅、氧化铝、氧化锆中的至少一种，且粉末原料还包括导电粉，导电粉可以包含氮化钛、氮化锆、碳氮化钛、碳化钛、碳化锆、碳化铊、碳化铪、硼化钛、硼化锆、硼化铊、硼化铪、硅化钼、碳化钨中的至少一种。
在本实施例中，可以理解的是，由于本实施例的发热体2是由金属毛毡材料或者多孔导电陶瓷材料所制成，因此发热体2整体会分布有多个可将雾化液从导液体1传导至发热体2的孔隙(图中未示意出)。
在本实施例中，在一些具体的应用场景中，本实施例的雾化芯可应用于电子雾化装置(例如电子烟)中，上述雾化液可以是液态的药物成分挥发物质、液态芳香成分释放物质、含有尼古丁的烟油或者其他加热可气化的挥发物质。其中，导液体1中的雾化液可由雾化器中的储液杯4所提供，接着导液体1再将雾化液传导至发热体2中。
在本实施例中，在具体实施时，发热体2的材料可优选为多孔导电陶瓷，相对于金属毛毡发热体或者其它类型的金属发热体，由于多孔导电陶瓷发热体发热时不易产生异味(此处可以理解的是，若本实施例的发热体2为金属毛毡发热体，则在实际使用中雾化芯10容易产生金属味而对用户的吸食口感产生一定的影响)，因此有利于提高使用者的吸食口感。此外，多孔导电陶瓷耐高温性能较好，能够承受800℃～1000℃的高温(而大多数雾化液的雾化温度一般为200℃～400℃)，因此即便雾化芯10因使用不当而发生干烧(例如，在一些将本实施例的雾化芯10应用于雾化器的使用场景中，当雾化器的储液杯中的雾化液已消耗完毕，用户仍然进行抽吸使用)，雾化芯10本身也不容易烧坏，从而有利于提高雾化芯10的使用寿命。
另外，在一些具体的应用场景中，当导液体1的材料为多孔陶瓷(即导液体1为多孔陶 瓷体)且发热体2的材料为多孔导电陶瓷(即发热体2为多孔导电陶瓷发热体)时，那么可以在制作雾化芯10的时候，将发热体2和导液体1共同烧结成一体，这样有利于减少雾化芯10自身的组装步骤以及降低雾化芯10的生产成本。
在本申请实施例的技术方案中，基于上述结构设计，一方面通过采用金属毛毡材料或者多孔导电陶瓷材料制成发热体2，使得发热体2可成为兼具导液和发热功能的多孔导电发热结构，进而使得雾化液可由导液体1流入发热体2的孔隙中，发热体2整体能够由内而外地对渗入到发热体2中的雾化液以及发热体2表面的雾化液全面充分地进行雾化，提升了使用者的吸食口感，能够更好地满足喜好吸食大烟雾的使用者的需求；另一方面通过将发热体2设计为包括连接部21和发热部22这两部分的结构，并将连接部21嵌入导液体1的通道11内侧壁以及将发热部22裸露于导液体1的通道11中，如此可减少发热体2中作为高温部分的发热部22与导液体1的接触面积，避免发热体2与导液体1之间的高温面积过大，雾化液雾化为汽态烟雾后因烟雾体积膨胀(或者是因雾化液雾化为汽态烟雾之前因过多的雾化液温度升高而产生较大的压强)而对发热体2的周边产生过大的压力，进而可避免在该压力的作用下迫使导液体1中的雾化液沿远离发热体2的方向流动，解决了脉冲式流入雾化液的技术问题；如此，在发热体2进行发热的过程中，当发热部22所含有的雾化液被加热并雾化时，发热体2中的雾化液含量减少，使得发热体2中的液体压强小于导液体1中的液体压强而形成负压，进而使得雾化液可顺畅地从导液体1中流入到发热体2中进行补充，从而使得发热体2在发热过程中能够在导液体1的通道11内持续性地产生充分的烟雾并能保障所产生的烟雾能够被通道11中的气流带走，以供用户使用，因此有效降低了当持续使用时间过长时雾化芯10会发生缺液干烧的风险，而且由于发热体2能够持续性地产生充分的烟雾，因此可有效提升使用者的吸食口感。
而且，与传统利用发热体产生的热量对导液体中的雾化液进行加热雾化的雾化芯(发热体工作时，特别是发热体刚开始工作时，雾化芯需要较大的功率才能出雾)相比，本申请实施例所提供的雾化芯10通过将雾化液由导液体1转移至发热体2中进行雾化，可在发热体2发热过程中，充分利用发热部22表面和内部所产生的热量共同来对发热部22中所存储的雾化液进行雾化，而不只是局限于发热体表面热量的利用，因此有效提高了热量的利用率，使得雾化芯10可实现小功率出雾的效果(即，相对于传统的雾化芯，发热体2工作时即便采用相对较小的功率亦能实现出雾)。
可选地，请参照图1-10，在本申请一示例性的实施例中，发热部22呈环状(图示性地，发热部22上设置有通气孔221，可以理解的是，该通气孔221的设置使得发热部22呈环状)，在通道11内发热部22沿通道11的周向环绕并外露于通道11的内侧壁设置。
在本实施例中，需要说明的是，所述环状可以是闭环状，也可以是具有断口的开环状，只要在大体上呈现为环状且保证导液体1的通道11中的空气能够正常流通即可，本实施例对 此不作具体的限定，图示性地，如图3所示，发热部22呈开环的圆环状；如图4所示，发热部22呈闭环的圆环状。当然在其它一些实施例中，发热部22也可以是呈三角形、椭圆形、矩形等形状的环状结构，只要能满足使用需求即可，本实施例对此不作具体的限定。其中，为使雾化液能够更加均匀地传导至发热部22中，优选地，呈环状的发热部22上的通气孔221位于发热部22的中部设置。
在本实施例中，基于上述结构设计，通过将发热部22设置为环状的，不仅可保证所产生的烟雾能够顺利地被通道11内的气流带走，而且可在发热体2的径向方向上缩短雾化液在发热部22中的传导路径，避免雾化液在发热部22中的传导路径过长而导致发热部22的局部位置出现供液不到位而发生缺液的现象，从而可有效避免发热部22出现局部干烧的问题。
进一步地，考虑到当发热体2为一体式结构时，当发热体2通电发热时，除了发热部22会导电发热之外，连接部21也会因有电流的通过而产生一定的热量，因此为避免连接部21产生过多的热量而降低雾化液从导液体1流入至发热体2中的速度(请参见背景技术，背景技术对此现象产生的原因有详细描述)，在本申请一示例性的实施例中，请参照图1-4和图9-10，连接部21上开设有至少一个用于阻断电流的断电缝隙211，断电缝隙211沿发热体2的径向的长度小于等于连接部21嵌设于导液体1的深度。如此设置，使得连接部21可实现轻微发热的效果(由于电流在连接部21中的传递被断电缝隙211阻断，因此此时连接部21的热量主要来自于发热部22所传递的少部分热量)，避免连接部21产生过多的热量而降低雾化液从导液体1流入至发热体2中的速度，保证发热部22中的雾化液在发热部22导电发热过程中能够及时进行补充，从而进一步降低了雾化芯10发生欠液干烧的风险。其中，在具体实施时，断电缝隙211的设置数量可结合连接部21的雾化液接收量和发热程度进行考量，一般而言，断电缝隙211设置得越多，电流的阻断效果越好，连接部21的发热量就越小(即，防止连接部21发热的效果就越好)，导液体1中的雾化液就可更加容易地通过连接部21流入到发热部22中，但与此同时，断电缝隙211设置得越多，也意味着连接部21的体积就越小，连接部21所能接收到的雾化液的量也就越少，图示性地，断电缝隙211设置有多个，且多个断电缝隙211沿发热体2的周向间隔布置。此外，在具体实施时，优选地，断电缝隙211沿发热体2的径向的长度等于连接部21嵌设于导液体1的深度，如此，使得断电缝隙211可实现更好的电流阻断效果，进而使得连接部21发热更少。
进一步地，参照图1、图4和图10，在本申请一示例性的实施例中，雾化芯10还包括相对设置的正极线脚31和负极线脚32，发热体2分别与正极线脚31、负极线脚32电连接，以使得在发热体2上形成两个并联设置的发热区(图中未进行标示)。具体地，发热体2相对的两端可通过焊接等方式分别与正极线脚31、负极线脚32实现电连接。
在本实施例中，基于上述结构设计，通过在发热体2上设置正极线脚31和负极线脚32，可在将雾化芯10应用于电子雾化装置中时，便于将发热体2电连接至电子雾化装置的电源部 分，同时基于实现在发热体2上形成两个并联设置的发热区的目的来布置正极线脚31和负极线脚32的位置，可避免因正极线脚31和负极线脚32相距过近而出现短路的问题，保证了发热部22能够正常通电发热而不会发生短路的问题。在本实施例中，需要说明的是，在一些具体的应用场景中，为满足用户对于“小口烟雾量”的使用需求，发热体2的数量可以设置为一个；在另一些具体的应用场景中，为满足用户对于“大口烟雾量”的使用需求，发热体2的数量可以设置为两个以上(此时，多个发热体2沿导液体1的轴向间隔布置)，此时发热体2之间可以通过共用一个负极线脚32和一个正极线脚31的方式实现并联连接；在又一些具体的应用场景中，为实现雾化芯10的“分控”功能(即，各个发热体2的工作可分别独立地进行控制)，以提高使用的灵活性，满足用户更多样的使用需求(例如，既可满足用户一时的对于“小口烟雾量”的使用需求，又可满足用户一时的对于“大口烟雾量”的使用需求；又例如，既可满足用户有时喜欢吸食A储液杯中雾化液的口味，又可满足用户有时喜欢吸食B储液杯中雾化液的口味；又例如，既可满足用户有时喜欢吸食A储液杯中含有尼古丁的雾化液的口味，又可满足用户有时喜欢吸食B储液杯中不含有尼古丁的雾化液的口味，这里所说的A储液杯和B储液杯都在同一雾化器100中)，发热体2的数量可以设置为两个以上(此时，多个发热体2沿导液体1的轴向间隔布置)，此时发热体2之间还可以通过共用其中一个电极线脚和分别各自配置另一个电极线脚的方式实现分别独立地对各个发热体2的工作进行控制。
进一步地，参照图1、图2和图9，在本申请另一示例性的实施例中，发热体2设置有一个，发热体2沿发热体2的径向上开设有一条防短路缝隙23，该防短路缝隙23使得发热体2在周向上形成有相隔开的两个端部。
在本实施例中，通过将发热体2设置为一个，使得雾化芯10在通电工作过程中可迅速产生较少的烟雾量，满足用户对于“小口烟雾量”的使用需求。同时，通过在发热体2沿发热体2的径向上开设有一条防短路缝隙23，可在将雾化芯10应用于电子雾化装置中时，将所形成的两个相隔开的端部分别电连接至电子雾化装置的电源部分的正负极，如此，可避免电源部分的正负极出现短接而发生短路的问题，保证了发热体2能够正常通电发热而不会发生短路的问题，从而可提高雾化芯10工作的可靠性。
进一步地，参照图1和图2，在本申请一示例性的实施例中，在发热体2上的防短路缝隙23的两侧，分别设置有正极线脚31和负极线脚32。如此，通过在防短路缝隙23的两侧分别设置正极线脚31和负极线脚32，可在将雾化芯10应用于电子雾化装置中时，便于将所形成的两个相隔开的端部分别电连接至电子雾化装置的电源部分的正负极，并且防短路缝隙23的设置可避免因正极线脚31和负极线脚32相距过近而出现短路的问题，保证了发热体2能够正常通电发热而不会发生短路的问题。
进一步地，参照图5和图10，在本申请另一示例性的实施例中，发热体2设置有多个， 且多个发热体2沿导液体1的轴向间隔布置。如此设置，使得雾化芯10在通电工作过程中可迅速产生更多的烟雾量，满足用户对于“大口烟雾量”的使用需求。
进一步地，参照图3和图5，在本申请另一示例性的实施例中，当发热体2设置有多个时，可在其中至少两个发热体2上，沿发热体2的径向上各开设有一条防短路缝隙23，防短路缝隙23使各个发热体2在周向上各形成有相隔开的两个端部(图中未进行标示)。如此设置，可在将雾化芯10应用于电子雾化装置中时，将所形成各个端部分别电连接至电子雾化装置的电源部分的正负极，如此，可避免电源部分的正负极出现短接而发生短路的问题，保证了其中至少两个发热体2能够正常通电发热而不会发生短路的问题，从而不仅可满足用户对于“大口烟雾量”的使用需求，而且可提高雾化芯10工作的可靠性。
其中，当发热体2设置有多个且其中至少两个发热体2开设有防短路缝隙23时，各个发热体2可均设置为并联连接，如此，使得雾化芯10通电工作后，各个金属毛毡发热体能够同步独立工作(此处应当理解的是，此种并联方式下的雾化芯10不具备“分控”的功能)，从而不仅可满足用户对于“大口烟雾量”的使用需求，而且有利于提高雾化芯10工作的可靠性。具体地，各个发热体2之间可通过以下方式实现并联连接：
参照图2、图3和图5，在本申请一示例性的实施例中，当发热体2设置有多个时，雾化芯10还包括一个正极线脚31和一个负极线脚32，每一发热体2上均开设有防短路缝隙23；在每一发热体2上，位于防短路缝隙23一侧的其中一个端部均与正极线脚31电连接，位于防短路缝隙23另一侧的另一个端部均与负极线脚32电连接。如此，各个开设有防短路缝隙23的发热体2之间通过共用一个负极线脚32和一个正极线脚31的方式实现并联连接，不仅可保证每一个发热体2都能够正常通电发热而不会发生短路的问题，而且可满足用户对于“大口烟雾量”的使用需求。
参照图2、图3和图6，在本申请另一示例性的实施例中，当发热体2设置有多个时，雾化芯10还包括一个负极线脚32以及与每一发热体2一一对应设置的多个正极线脚31，每一发热体2上均开设有防短路缝隙23；在每一发热体2上，位于防短路缝隙23一侧的其中一个端部均与负极线脚32电连接，位于防短路缝隙23另一侧的另一个端部分别与各自的正极线脚31电连接。如此，各个开设有防短路缝隙23的发热体2之间通过共用其中一个电极线脚和分别各自配置另一个电极线脚的方式实现并联连接，不仅可保证每一个发热部22都能够正常通电发热而不会发生短路的问题，而且可实现雾化芯10的“分控”功能，从而提高了雾化芯10使用的灵活性，能够满足用户更多样的使用需求(例如，既可满足用户一时的对于“小口烟雾量”的使用需求，又可满足用户一时的对于“大口烟雾量”的使用需求；又例如，既可满足用户有时喜欢吸食A储液杯中雾化液的口味，又可满足用户有时喜欢吸食B储液杯中雾化液的口味；又例如，既可满足用户有时喜欢吸食A储液杯中含有尼古丁的雾化液的口味，又可满足用户有时喜欢吸食B储液杯中不含有尼古丁的雾化液的口味，这里所说的A储液杯 和B储液杯都在同一雾化器100中)。
参照图2、图3和图7，在本申请又一示例性的实施例中，当发热体2设置有多个时，雾化芯10还包括与每一发热体2一一对应设置的多个负极线脚32和多个正极线脚31，每一发热体2上均开设有防短路缝隙23；且在每一发热体2上，位于防短路缝隙23一侧的其中一个端部分别与各自的负极线脚32电连接，位于防短路缝隙23另一侧的另一个端部分别与各自的正极线脚31电连接。如此，各个开设有防短路缝隙23的发热体2之间通过分别各自配置两个电极线脚的方式实现并联连接，不仅可保证每一个发热部22都能够正常通电发热而不会发生短路的问题，而且亦可实现雾化芯10的“分控”功能，从而提高了雾化芯10使用的灵活性，能够满足用户更多样的使用需求(例如，既可满足用户一时的对于“小口烟雾量”的使用需求，又可满足用户一时的对于“大口烟雾量”的使用需求)。
此外，当发热体2设置有多个且其中至少两个发热体2开设有防短路缝隙23时，各个发热体2还可均设置为串联连接，如此，使得雾化芯10在通电工作过程中可迅速产生更多的烟雾量，满足用户对于“大口烟雾量”的使用需求。具体地，各个发热体2之间可通过以下方式实现串联连接：
参照图1和图8，在本申请一示例性的实施例中，雾化芯10还包括一个正极线脚31、一个负极线脚32和若干根导线33，每一发热体2上均开设有防短路缝隙23；沿通道11的轴向上，负极线脚32与第一个发热体2的其中一个端部电连接，正极线脚31与最后一个发热体2的其中一个端部电连接，且剩余的其它端部沿着通道11的轴线方向通过若干根导线33依次顺序连接，从而使得各个发热体2之间可实现串联连接，使得雾化芯10在通电工作过程中可迅速产生更多的烟雾量，满足用户对于“大口烟雾量”的使用需求。
进一步地，参照图1和图9，在本申请一示例性的实施例中，发热体2的体积小于导液体1的体积。如此设置，使得在发热体2通电工作之前，导液体1中的雾化液含量会多于发热体2中的雾化液含量，进而当发热体2中的雾化液因加热雾化而减少时，发热体2与导液体1之间的压差会更大，使得发热部22一侧会形成更强的负压，进而使得雾化液可从导液体1中更加迅速地流入到发热体2中进行雾化液的补充，从而不仅可进一步降低雾化芯10发生缺液干烧的风险，而且有利于提高雾化芯10的雾化效率(即单位时间内可产生更多的烟雾)。
可选地，在本申请的一些实施例中，当发热体2由多孔导电陶瓷制成时，为使得雾化液在发热体2中有合适的传递速度，发热体2的孔隙率可以设置为30％～60％。
可选地，请参照图13、图14、图16和图18，在本申请另一示例性的实施例中，发热体2设置为发热体2的两端分别沿通道22的两端延伸。
在本实施例中，需要说明的是，在具体实施时，发热体2可以平行于通道11的轴线设置，也可以与通道11的轴线呈夹角设置，只要使得发热体2的两端分别沿通道11的两端延 伸即可。其中，当发热体2平行于通道11的轴线设置时，发热体2的两端沿通道11的轴线方向延伸；当发热体2与通道11的轴线呈夹角设置时，发热体2倾斜地嵌设于通道11的内侧壁上。
在本实施例中，基于上述结构设计，通过将发热体2设置为具有相对的两端且其两端分别沿通道22的两端延伸的形状，不仅可保证所产生的烟雾能够顺利地被通道11内的气流带走，而且有利于提高连接部21与导液体1之间的接触面积，一方面使得整个发热体2能够更加稳定地固定于导液体1的通道11中，另一方面使得单位时间内导液体1中的雾化液能够通过连接部21更多地传导至发热部22中进行加热雾化，从而使得发热体2能够持续性地产生更加充分的烟雾，有利于进一步提升使用者的吸食口感。
进一步地，考虑到在发热体2为一体式结构的情况下，当发热体2通电发热时，除了发热部22会导电发热之外，连接部21也会因有电流的通过而产生一定的热量，因此为避免连接部21产生过多的热量而降低雾化液从导液体1流入至发热体2中的速度(请参见背景技术，背景技术对此现象产生的原因有详细描述)，在本申请一示例性的实施例中，请参照图13-14以及图16-18，连接部21上开设有至少一条用于阻断电流的断电缝隙211。如此设置，由于电流在连接部21中的传递被断电缝隙211阻断，此时连接部21的热量主要来自于发热部22所传递的少部分热量，从而使得连接部21可实现轻微发热的效果，避免连接部21产生过多的热量而降低雾化液从导液体1流入至发热体2中的速度，保证发热部22中的雾化液在发热部22导电发热过程中能够及时进行补充，从而进一步降低了雾化芯10发生欠液干烧的风险。在具体实施时，断电缝隙211的设置数量可结合连接部21的雾化液接收量和发热程度进行考量，一般而言，断电缝隙211设置得越多，电流的阻断效果越好，连接部21的发热量就越小，即，防止连接部21发热的效果就越好，导液体1中的雾化液就可更加容易地通过连接部21流入到发热部22中。但与此同时，断电缝隙211设置得越多，也意味着连接部21的体积就越小，连接部21所能接收到的雾化液的量也就越少，图示性地，断电缝隙211设置有多个，且多个断电缝隙211沿连接部21的长度方向间隔布置。参照图14，在一些具体的应用场景中，断电缝隙211设置于沿连接部21的径向延伸的方向上，且断电缝隙211的长度小于等于连接部21嵌设于导液体1的深度，如此，相比于将断电缝隙211设置为断电缝隙211沿连接部21的径向的长度大于连接部21嵌设于导液体1的深度，可增大连接部21与导液体1的接触面积，从而有利于提高雾化液从导液体1流入到发热体2中的供应量，使得发热体2更不易发生缺液干烧的现象，其中，优选地，断电缝隙211沿连接部21的径向的长度等于连接部21嵌设于导液体1的深度，如此，使得断电缝隙211可实现更好的电流阻断效果，进而使得连接部21发热更少，导液效果更好；参照图23，在另一些具体的应用场景中，断电缝隙211设置于沿连接部21的径向延伸的方向上，且断电缝隙211的大于连接部21嵌设于导液体1的深度，如此，相比于将断电缝隙211设置为断电缝隙211沿连接部21的径向的长度小于等 于连接部21嵌设于导液体1的深度，可使得通道11中的气流能够通过露出部分的断电缝隙211，从而使得发热部22所产生的烟雾可更加迅速地被通道11中的气流带走。此外，在具体实施时，整个发热体2可以是片状、块状、波浪状、层叠状等形状，连接部21的形状可以是矩形、锯齿形、波浪形等形状，发热部22的形状也可以是矩形、锯齿形、波浪形等形状，只要能保证雾化芯10通电工作的过程中，连接部21能够正常为发热部22传导雾化液，发热部22能够正常将发热部22中所含的雾化液加热雾化即可，本实施例对此不作具体的限制。
进一步地，请参照图15，在本申请一示例性的实施例中，发热体2设置有一个，在发热体2的两端中，其中一端电连接有正极线脚31，另一端电连接有负极线脚32，图示性地，正极线脚31连接于发热体2沿其长度方向的一端，负极线脚32连接于发热体2沿其长度方向的另一端。
在本实施例中，通过将发热体2设置为一个，使得雾化芯10在通电工作过程中可迅速产生较少的烟雾量，满足用户对于“小口烟雾量”的使用需求。同时，通过在发热体2的两端分别设置正极线脚31和负极线脚32，可在将雾化芯10应用于电子雾化装置中时，便于将发热体2与电子雾化装置的电源部分进行电连接，并且通过将正负极线脚分别设置在发热体2的两端，可避免因正极线脚31和负极线脚32相距过近而出现短路的问题，保证了发热体2能够正常通电发热而不会发生短路的问题。
进一步地，请参照图13和图14，在本申请另一示例性的实施例中，发热体2设置有多个，且多个发热体2沿通道11的周向间隔布置。如此设置，使得雾化芯10在通电工作过程中可迅速产生更多的烟雾量，满足用户对于“大口烟雾量”的使用需求。
在本实施例中，具体实施时，各个发热体2的大小可以是均都相同的，也可以是互不相同的，还可以是部分相同的，本实施例对此不作具体的限制。此外，在一些具体的应用场景中，至少两个发热体2沿通道11的轴向高低错位设置，例如，参照图14，假设发热体2设置有三个(图14中只示意出了其中两个)，则在具体实施时，可以使得第一个发热体2的上端面与第二个发热体2的上端面之间存在高度差，并使得第一个发热体2的上端面与第三个发热体2的上端面相平齐；也可以使得第一个发热体2的下端面与第二个发热体2的下端面之间存在高度差，并使得第一个发热体2的下端面与第三个发热体2的下端面相平齐；还可以也使得三个发热体2的上端面两两之间均存在高度差，当然还可以也使得三个发热体2的下端面两两之间均存在高度差，如此等等，此处不再赘述。
而在另一些具体的应用场景中，至少两个发热体2的一端在通道11的轴向上的高度差为零，且另一端在通道11的轴向上的高度差也为零，例如，参照图14，假设发热体2设置有三个(图14中只示意出了其中两个)，则在具体实施时，可以使得三个发热体2的上端面均相平齐，并使得三个发热体2的下端面也均相平齐；也可以使得第一个发热体2与第二个发 热体2的上、下端面均相平齐，并使得第一个发热体2与第三个发热体2的上、下端面均存在高度差，如此等等，此处不再赘述。
进一步地，在本申请一示例性的实施例中，当发热体2设置有多个时，各个发热体2可均设置为并联连接，如此，使得雾化芯10通电工作后，各个发热体2能够同步独立工作，从而不仅可满足用户对于“大口烟雾量”的使用需求，而且有利于提高雾化芯10工作的可靠性。具体地，各个发热体2之间可通过以下方式实现并联连接：
请参照图14和图19，在本申请一示例性的实施例中，雾化芯10还包括一个正极线脚31和一个负极线脚32，每一发热体2沿通道11的轴向均具有相互远离的第一端和第二端；在每一发热体2上，第一端均与正极线脚31电连接，第二端均与负极线脚32电连接。如此，各个发热体2之间通过共用一个正极线脚31和一个负极线脚32的方式实现并联连接，使得雾化芯10通电工作后，各个发热体2能够同步独立工作(此处应当理解的是，此种并联方式下的雾化芯10不具备“分控”的功能)，从而不仅可满足用户对于“大口烟雾量”的使用需求，而且有利于提高雾化芯10工作的可靠性(具体表现为，任意一个或多个发热体2即便无法正常工作，也不会影响到其余发热体2的正常工作)。需要说明的是，图19所示是发热体2和正负极线脚相连的展开图，将图19所示的发热体2和正负极线脚围合后即能形成图14所示的形状。
进一步地，请参照图14和图20，在本申请另一示例性的实施例中，雾化芯10还包括一个负极线脚32以及与每一发热体2一一对应设置的多个正极线脚31，每一发热体2沿通道11的轴向均具有相互远离的第一端和第二端；在每一发热体2上，发热体2的第一端与各自的正极线脚31电连接，发热体2的第二端均与负极线脚32电连接。如此，各个发热体2之间通过共用其中一个电极线脚和分别各自配置另一个电极线脚的方式实现并联连接，可实现雾化芯10的“分控”功能，从而提高了雾化芯10使用的灵活性，能够满足用户更多样的使用需求。例如，既可满足用户一时的对于“小口烟雾量”的使用需求，又可满足用户一时的对于“大口烟雾量”的使用需求；又例如，既可满足用户有时喜欢吸食A储液杯4中雾化液的口味，又可满足用户有时喜欢吸食B储液杯4中雾化液的口味；又例如，既可满足用户有时喜欢吸食A储液杯4中含有尼古丁的雾化液的口味，又可满足用户有时喜欢吸食B储液杯4中不含有尼古丁的雾化液的口味，这里所说的A储液杯4和B储液杯4都在同一雾化器100中。
进一步地，请参照图14和图21，在本申请又一示例性的实施例中，雾化芯10还包括与每一发热体2一一对应设置的多个负极线脚32和多个正极线脚31，每一发热体2沿通道11的轴向均具有相互远离的第一端和第二端。在每一发热体2上，发热体2的第一端与各自的正极线脚31电连接，发热体2的第二端与各自的负极线脚32电连接。如此，各个发热体2之间通过分别各自配置两个电极线脚的方式实现并联连接，亦可实现雾化芯10的“分控”功 能，从而提高了雾化芯10使用的灵活性，能够满足用户更多样的使用需求。例如，既可满足用户一时的对于“小口烟雾量”的使用需求，又可满足用户一时的对于“大口烟雾量”的使用需求。
此外，当发热体2设置有多个时，各个发热体2还可均设置为串联连接，如此，使得雾化芯10在通电工作过程中可迅速产生更多的烟雾量，满足用户对于“大口烟雾量”的使用需求。具体地，各个发热体2之间可通过以下方式实现串联连接：
请参照图14和图22，在本申请一示例性的实施例中，雾化芯10还包括一个正极线脚31、一个负极线脚32和若干根导线33，每一发热体2沿通道11的轴向均具有相互远离的第一端和第二端。在通道11的周向上，正极线脚31与第一个发热体2的第一端电连接，负极线脚32与最后一个发热体2的第一端电连接，且剩余的其它第一端和第二端沿通道11的周向通过若干根导线33依次顺序连接，从而使得各个发热体2之间可实现串联连接，使得雾化芯10在通电工作过程中可迅速产生更多的烟雾量，满足用户对于“大口烟雾量”的使用需求。
进一步地，请参照图13和图14，在本申请一示例性的实施例中，发热体2嵌入通道11的内侧壁的边长大于等于发热体2沿通道11的径向延伸的边长，图示性地，发热体2沿通道11的轴向延伸的长度大于发热体2沿通道11的径向延伸的宽度。如此设置，一方面可使得连接部21与导液体1之间能够充分接触，进而使得发热体2可具备较为充足的进液面积，另一方面可在通道11的径向上使得雾化液在发热体2中的传导路径较短，进而使得导液体1中的雾化液可更快地补充至发热部22中；从而，有利于更好地避免发热部22出现局部干烧的问题。
进一步地，请参照图13和图14，在本申请一示例性的实施例中，发热体2的体积小于导液体1的体积。如此设置，使得在发热体2通电工作之前，导液体1中的雾化液含量会多于发热体2中的雾化液含量，进而当发热体2中的雾化液因加热雾化而减少时，发热体2与导液体1之间的液压压差会更大，使得发热部22一侧会形成更强的负压，进而使得雾化液可从导液体1中更加迅速地流入到发热体2中进行雾化液的补充，从而不仅可进一步降低雾化芯10发生欠液干烧的风险，而且有利于提高雾化芯10的雾化效率，即单位时间内可产生更多的烟雾。
对应地，参照图1-24，本申请实施例还提供一种电子雾化装置，该电子雾化装置包括雾化器100，该雾化器100包括储液杯4、雾化芯支架5、气道6以及上述任一实施例中的雾化芯10，其中：
储液杯4上设置有至少一个出液孔(图中未标示)；
雾化芯支架5上设置有至少一个进液孔51，雾化芯支架5套设在雾化芯10外部，出液孔与进液孔51相连通，雾化芯支架5的内壁与导液体1的外壁相互贴设在一起；
导液体1中的通道11与气道6相连通。
在本实施例中，具体地，该电子雾化装置可为电子烟，得益于上述雾化芯10的改进，本实施例的雾化器100和电子雾化装置具有与上述雾化芯10相同的技术效果，此处不再赘述。
进一步地，请参照图12和图24，在本申请一示例性的实施例中，发热体2在通道11的周向上与出液孔和进液孔51相邻而设。如此设置，可缩短雾化液从储液杯4传导至发热体2中的路径，使得储液杯4中的雾化液可更加迅速地补充至发热体2中，从而有利于进一步降低当持续使用时间过长时雾化芯10发生缺液干烧的风险。
进一步地，在本申请的一些实施例中，上述电子雾化装置还包括主机电源系统(图中未示意出)，其中，主机电源系统与雾化器电连接。具体地，主机电源系统包括电池和控制电路板，控制电路板分别与电池、发热体2电连接。其中，控制电路板用于控制发热体2的工作，使用时，通过控制电路板可控制电池为发热体2供电，使得发热体2对所吸收的雾化液进行加热雾化，而上述电池可以是锂电池等类型的电源。
需要说明的是，本申请公开的雾化芯10、雾化器100及电子雾化装置的其它内容可参见现有技术，此处不再赘述。
