实施例
本发明的另一实施例中，如图1~图4所示，一种双面发热的玻璃发热片，设置了基体1，渗透区2，第一加热元件3，以及第二加热元件4，所述基体1由非晶无机非金属材料制成，所述基体1具有第一面11和第二面12；所述渗透区2设于基体1、并将第一面11与第二面12连通，且至少在负压作用下可以让液体通过；所述第一加热元件3设于第一面11，所述第一加热元件3用于对经过第一面11进入渗透区2的液体进行预热；所述第二加热元件4设于第二面12，所述第二加热元件4用于对渗透区2的液体进行加热、并形成雾化气体。渗透区2由多个微孔21构成，多个所述微孔21从第一面11贯通到第二面12，采用多个微孔21设计的渗透区2，在加工过程中可直接通过激光打孔加工形成，对采用玻璃基体1的结构加工方便，适合大批量生产。
上述实施例中，微孔21的直径尺寸为0.01mm~0.5mm，采用较小尺寸的微孔21，目的是在不使用时能够锁住液体，不会出现漏液现象。
以上各个实施例中，第一加热元件3的加热温度与第二加热元件4的加热温度相同，即第一加热元件3的电阻与第二加热元件4的电阻相同，可将两者连接单独连接导电结构，在通电时产生同样的热量，提升加热效率。
以上各个实施例中，针对玻璃发热片进行测试，并对所测试的参数与市场主流的陶瓷发热芯进行对比，详细见下表：
结论：玻璃发热片工作温度比市场主流陶瓷发热芯的工作温度低，但能达到接近陶瓷发热芯的平均消耗量，且相比陶瓷发热芯更加安全、使用寿命更长。
备注：
1.烟气总粒相物传输量的变化测试方法采用电子烟国标（GB 41700-2022）中“附录D 电子烟标准抽吸条件”中的测试方法。
2.烟气总粒相物传输量的变化测试结果参考雾化电子烟装置通用技术规范（T/CECC 001-2021）中“附录C 雾化气体捕集量的测定”的相关要求，雾化气体平均消耗量与用户体验相关。
实施例
参阅图1~图4所示，对上述两个实施例3和/或 4的进一步改进为，第一加热元件3包括第一接触端31以及第一发热线路32，所述第一接触端31用于接电，所述第一发热线路32通过渗透区2，所述第一接触端31设有两个、并分别为正负极接触端，进一步的实施例中，第二加热元件4包括第二接触端41以及第二发热线路42，所述第二接触端41与第一接触端31电连接，所述第二发热线路42通过渗透区2，所述第二接触端41设有两个、并分别为正负极接触端；同于上述实施例，本实施例中，采用两个的第二接触端41用于第二发热线路42供电，同时第二接触端41与第一接触端31电连接，目的是用于第一发热线路32供电，具体来说，第一发热线路32的电阻小于第二发热线路42的电阻，能够在同样供电作用下产生不同的发热温度，进而实现单接电双温度的控制。
上述实施例5中，在加热时，两个发热元件的电阻值为1.0~1.3Ω，干烧温度为600~700℃，发热线路发热效率为0.3s可达到100℃以上。
一种包括上述任意实施例的雾化装置，采用了上述结构的发热片，能够对液体雾化前进行预热，能够保证后续的加热效率和液体雾化后的口感更佳丰富，更具层次感。
本发明采用非晶无机非金属材料作为基础，优选为玻璃，并在双面分别设置第一加热元件3和第二加热元件4，在雾化装置上使用时，可先通过第一加热元件3对被雾化的液体进行预热，预热后再经过第二加热元件4进行加热形成气溶胶气体，在预热后再加热，减少了液体从冷凝状态至加热的一个过程，可更加快速的进行加热雾化，进而提升雾化效果，在针对不同的液体雾化后也能具有不同的层次感，在雾化使用中效果更佳；解决了现有在液体由冷凝至加热需要一个较长的过程，也杜绝了使用时雾化效率低，雾化出料的气雾口感没有层次感的问题。具体是，设置了基体1，渗透区2，第一加热元件3，以及第二加热元件4，所述基体1由非晶无机非金属材料制成，所述基体1具有第一面11和第二面12；所述渗透区2设于基体1、并将第一面11与第二面12连通，且至少在负压作用下可以让液体通过；所述第一加热元件3设于第一面11，所述第一加热元件3用于对经过第一面11进入渗透区2的液体进行预热；所述第二加热元件4设于第二面12，所述第二加热元件4用于对渗透区2的液体进行加热、并形成雾化气体。基体1上具有两个面，两个面通过渗透区2连通，第一加热元件3可从液体导向中现将液体预热，经过渗透区2进入到第二加热元件4时再进行加热雾化，对液体预热后雾化，雾化效率高。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
