 本发明的实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1所示，本发明第一实施例的用于电子烟的雾化片，包括片状的雾化片本体11、设置在雾化片本体11上的孔部12。在电子烟中，雾化片本体11的表面用于与导液件接触，两者的接触面积大，使得雾化面积也大，雾化均匀。孔部12贯穿雾化片本体11相对的两个表面，通过对孔部12的具体设置，可以调节雾化片的阻值，还可起到导液及通气的作用。
其中，雾化片本体11可以是不锈钢、镍合金、镍铬合金、钛合金等材料制成的金属片，制成方式可以是激光切割、化学腐蚀、机加工及冲压等中的至少一种。雾化片本体11的形状不限，例如可以是多边形、椭圆形等各种形状。
雾化片本体11的厚度为0.01 mm-0.2mm。
在本实施例中，孔部12包括多个通孔121。多个通孔121在雾化片本体11上均匀间隔分布，可以排成多行和/或多列，使整个雾化片阻值分布均匀，热量分布均匀，雾化均匀。通孔121可以是圆孔、多边形孔等规则孔和不规则孔中的一种或多种。
本实施例中，雾化片的阻值为0.1-0.3Ω。
根据需要，还可以在孔部12的通孔121内填充陶瓷等绝缘耐高温的多孔材料，增强雾化片的导液性能。
如图2所示，本发明第二实施例的用于电子烟的雾化片，包括片状的雾化片本体21、设置在雾化片本体21上的孔部22。在电子烟中，雾化片本体21的表面用于与导液件接触，两者的接触面积大，使得雾化面积也大，雾化均匀。孔部22贯穿雾化片本体21相对的两个表面，通过对孔部12的具体设置，可以调节雾化片的阻值，还可起到导液及通气的作用。
其中，雾化片本体21可以是不锈钢、镍合金、镍铬合金、钛合金等材料制成的金属片，制成方式可以是激光切割、化学腐蚀、机加工及冲压等中的至少一种。雾化片本体21的形状不限，例如可以是多边形、椭圆形等各种形状。

第一通孔组221包括多个间隔分布的第一通孔2210，第二通孔组222包括多个间隔分布的第二通孔2220。其中，第二通孔组222的孔密度小于第一通孔组221的孔密度，从而多个第一通孔2210的分布密度大于多个第二通孔2220的分布密度，使得雾化片整体的热量分布较为均匀。
本实施例中，雾化片的阻值为0.1-0.3Ω。
根据需要，还可以在第一通孔2210和第二通孔2220内填充陶瓷等绝缘耐高温的多孔材料，增强雾化片的导液性能。
如图3、4所示，本发明第三实施例的用于电子烟的雾化片，包括片状的雾化片本体31、设置在雾化片本体31上的孔部32。在电子烟中，雾化片本体31的表面用于与导液件接触，两者的接触面积大，使得雾化面积也大，雾化均匀。孔部32贯穿雾化片本体31相对的两个表面，通过对孔部12的具体设置，可以调节雾化片的阻值，还可起到导液及通气的作用。
雾化片的阻值可为0.1-0.3Ω。
其中，雾化片本体31可以是不锈钢、镍合金、镍铬合金、钛合金等材料制成的金属片，制成方式可以是激光切割、化学腐蚀、机加工及冲压等中的至少一种。雾化片本体31的形状不限，例如可以是多边形、椭圆形等各种形状。雾化片本体31的厚度为0.01 mm-0.2mm。

气流通道孔44可通过冲压方式形成在雾化片本体41上，在冲压时还可以冲切到部分的通孔421，使得部分通孔421被切开而与气流通道孔44相连通。气流通道43孔大于通孔421。对于圆形的气流通道孔44，其直径则大于通孔421的直径。
雾化片上气流通道孔44的设置，减少了气流的拐弯次数，有效防止烟油的冷凝积聚。
本实施例中，雾化片的阻值为0.1-0.3Ω。

优选地，第一编织网片511的孔隙密度小于第二编织网片512的孔隙密度，使得两者的疏密不一致，从而雾化片的可选阻值范围广，热分布更为均匀。本实施例的雾化片的阻值为0.1-5Ω。
根据需要，本实施例的雾化片还可以包括连接导体（未图示），设置在雾化片本体51的两端，用于与电子烟中电源的正极和负极连接。
