 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、2所示，本发明第一实施例的一体式加热雾化模块，包括电热体10、纤维导液体20以及支架体30。电热体10、纤维导液体20和支架体30自内到外依次配合在一起，形成整体的雾化模块，其中纤维导液体20用于吸附烟液，电热体10用于在通电后发热，对烟液进行加热雾化以形成烟雾；支架体30能够作为纤维导液体20外部保护结构，避免纤维导液体20及电热体10受外力作用发生形变，还作为支撑结构对整个雾化模块在电子烟中起到支撑固定的作用。
其中，纤维导液体20设有贯穿其相对两端的中心通道21，电热体10穿插并贴合在中心通道21内，与纤维导液体20充分稳定接触。电热体10的两个电极连接端12分别伸出纤维导液体20外，用于连接电源。支架体30套设在纤维导液体20外，与纤维导液体20卡接而相对固定。支架体30的整体长度大于纤维导液体20的长度，支架体30的相对两端分别伸长在纤维导液体20的相对两端外，这样当支架体30套设在纤维导液体20外时，可以将整个纤维导液体20容纳在其内部。
具体地，在本实施例中，电热体10包括电热主体部11，电热主体部11由电热丝绕制形成的螺旋状结构，电热丝的两个端部分别形成电热体10的两个电极连接端12。两个电极连接端12伸出纤维导液体20外，同时也伸出支架体30外，用于连接电源的正负极。
电热主体部11以其长度方向平行中心通道21的长度方向配合在其中，并且与中心通道21的内壁面贴合，贴合深度为0-0.5mm，实现两者之间的充分接触。电热主体部11的横截面形状也与中心通道21的横截面形状对应设置，例如均为圆形、椭圆形，或者均为方形等多边形。
两个电极连接端12可均平行电热主体部11的长度方向向外延伸。其中，一个电极连接端12向另一电极连接端12方向弯折延伸，使得两个电极连接端12处于电热体10的同一侧，这样电热体10的两个电极连接端12伸出在其同一端外侧，方便在电子烟中的装配以及与电子烟的电源连接。
在材料方面，电热体10采用纯金属、金属合金、碳纤维、导电型金属化合物纤维、导电高分子纤维中一种或多种制成。纯金属包括纯镍、纯钛；金属合金包括不锈钢、钛合金、镍铬及铁铬铝。在选择纯金属时，可以选择纯镍和纯钛中至少一种；在选择金属合金时，可以选择不锈钢、钛合金、镍铬及铁铬铝中一种或多种。
纤维导液体20用于在电子烟中与储液腔导液连接，其采用天然有机棉、合成纤维、无机纤维（如玻璃纤维等）、金属纤维（如不锈钢纤维等）中一种或多种制成。在制备方式上，纤维导液体20通过水刺、压制成型、模压成型、压注成型、注射成型、沉积等方式制成，无需粘结剂，只需要水和短纤维即可，保证口感纯净，成型温度为40℃-200℃，节能降耗。
在形态上，纤维导液体20可以是各种形状的结构体，如圆形柱体、方形柱体等等。纤维导液体20的中心通道21可以与纤维导液体20的外周形状一致，如均为圆形或多边形，也可以不一致，而与电热体10形状一致。
在尺寸方面，纤维导液体20也与电热体10中电热主体部11的长度对应设置，优选等于或大于电热主体部11的长度，以使电热主体部11的整体容纳在中心通道21内，避免部分端部露出在纤维导液体20外而造成干烧的问题。
支架体30为硬质结构件，包覆在纤维导液体20的外周上，对其起到支撑保护等作用。支架体30上设有孔结构等露出纤维导液体20，便于纤维导液体20吸附烟液。支架体30可以是不锈钢管、玻纤管、机加件、塑胶件或硅胶件。
在本实施例中，支架体30呈筒状结构，上下贯通且连通纤维导液体20的中心通道21，空气可自支架体30端部进入，电热体10加热雾化形成的烟雾也从支架体30端部输出。支架体30上设有至少一个贯穿其相对两壁面的进液孔31，用于连通纤维导液体20和储液腔。
进一步地，纤维导液体20的外周表面设有至少一个凸出的导液部22，导液部22和支架体30上的进液孔31相适配设置。导液部22配合在进液孔21内，导液部22的表面与支架体30的外表面平齐或者凸出支架体30的外表面上。导液部22通过在进液孔21内的配合露出支架体30外，不仅利于吸附烟液，纤维导液体20还通过导液部22配合在进液孔31内而与支架体30卡接固定。
作为优选，导液部22设有两个或以上，沿着纤维导液体20的外周间隔排布，支架体30上的进液孔31对应设有两个或以上。多个导液部22在纤维导液体20上可以处于同一高度，也可以不同高度分布。
本实施例的一体式加热雾化模块制备时，将预先成型后电热体10和支架体30进行装配：将电热体10定位在支架体30内部。以水作为溶剂，纤维分散在水内形成纤维导液体20的料体，通过水刺沉积、40℃-200℃烘烤的方式成型在电热体10和支架体30之间，水蒸发后留下纤维部分，即为纤维导液体20，固定连接在电热体10和支架体30之间。
如图3所示，本发明第二实施例的一体式加热雾化模块，包括电热体10、纤维导液体20以及支架体30。电热体10、纤维导液体20和支架体30自内到外依次配合在一起，形成整体的雾化模块，其中纤维导液体20用于吸附烟液，电热体10用于在通电后发热，对烟液进行加热雾化以形成烟雾；支架体30能够作为纤维导液体20外部保护结构，避免纤维导液体20及电热体10受外力作用发生形变，还作为支撑结构对整个雾化模块在电子烟中起到支撑固定的作用。
本实施例中，纤维导液体20和支架体30具体可参考上述第一实施例，在此不再赘述。
本实施例不同于上述第一实施例的是：电热体10中，电热主体部11由电热片弯曲形成的筒状结构。电热体10的两个电极连接端12相间隔连接在电热主体部11的同一端上，伸出纤维导液体20和支架体30外，用于连接电源的正负极。电热片可以呈网状（如图3中所示），或者通过多个相同或不同通孔排布而呈镂空状。
本实施例中，网状或镂空状的电热片形成的电热主体部11，加热面积较于螺旋状的电热主体部11的加热面积大，与纤维导液体20的接触面积也更大，因此能够增加烟雾量，传热也更为均匀，防炸油效果更好。
如图4、5所示，本发明第三实施例的一体式加热雾化模块，包括电热体10、纤维导液体20以及支架体30。电热体10、纤维导液体20和支架体30自内到外依次配合在一起，形成整体的雾化模块，其中纤维导液体20用于吸附烟液，电热体10用于在通电后发热，对烟液进行加热雾化以形成烟雾；支架体30能够作为纤维导液体20外部保护结构，避免纤维导液体20及电热体10受外力作用发生形变，还作为支撑结构对整个雾化模块在电子烟中起到支撑固定的作用。
本实施例中，电热体10、纤维导液体20和支架体30具体可参考上述第一实施例，在此不再赘述。
本实施例较于上述第二实施例，纤维导液体20内还设有至少一贯穿纤维导液体20相对两端的补气通道23。补气通道23位于中心通道21的至少一侧，与中心通道21相连通。在纤维导液体20及支架体30的横向方向上，补气通道23与支架体30上的进液孔31正对（不连通），并且还与电热体10相错开。
具体地，电热体10的电热主体部11由电热片弯曲形成，电热片的相对两侧相对并且不相接，在电热主体部11上形成侧面开缝，在纤维导液体20内部，电热主体部11以其侧面开缝朝向补气通道23，从而避免电热主体部11的结构部分对应在补气通道23处，实现错开。
雾化模块通过补气通道23进行补气，保证雾化模块供液充足，避免雾化模块从电热体10部位补气导致电热体10局部供油不足（积碳、影响口感），提高口感一致性。
如图6所示，本发明第四实施例的一体式加热雾化模块，包括电热体10、纤维导液体20以及支架体30。电热体10、纤维导液体20和支架体30自内到外依次配合在一起，形成整体的雾化模块，其中纤维导液体20用于吸附烟液，电热体10用于在通电后发热，对烟液进行加热雾化以形成烟雾；支架体30能够作为纤维导液体20外部保护结构，避免纤维导液体20及电热体10受外力作用发生形变，还作为支撑结构对整个雾化模块在电子烟中起到支撑固定的作用。
本实施例中，纤维导液体20和支架体30具体可参考上述第一实施例，在此不再赘述。
本实施例不同于上述第一实施例的是：电热体10包括至少两个电热单元。电热单元可以相对和/或相邻贴合在纤维导液体20的中心通道21内壁面上。
其中，每一电热单元包括电热片110、相间隔连接在电热片110上的两个电极连接端120。电极连接端120伸出纤维导液体20和支架体30外，用于连接电源的正负极。电热片110可以呈网状，或者通过多个相同或不同通孔排布而呈镂空状。
较于单个电热主体部11，本实施例的电热体20包括两个或以上的电热单元，加热面积更大，产生的烟雾量也更大，传热也更为均匀，防炸油效果更好。
另外，对于两个或以上的电热单元的设置，中心通道21可以是多边形通道，每一电热单元的电热片110紧密贴合在中心通道21的一内壁面上。当然，中心通道21也可以是圆形通道，电热单元的电热片110弧形设置并吻合在中心通道21的内壁面上。
进一步地，电热片110朝向纤维导液体20的表面的上端和/或下端还可设有至少一组卡钩，卡钩用于伸入纤维导液体20内部，提高电热体10和纤维导液体20的贴合牢固度。
纤维导液体20内还可根据需要也设有补气通道，具体可参考第三实施例。
如图7、8所示，本发明第五实施例的一体式加热雾化模块，包括电热体10、纤维导液体20以及支架体30。电热体10、纤维导液体20和支架体30自内到外依次配合在一起，形成整体的雾化模块，其中纤维导液体20用于吸附烟液，电热体10用于在通电后发热，对烟液进行加热雾化以形成烟雾；支架体30能够作为纤维导液体20外部保护结构，避免纤维导液体20及电热体10受外力作用发生形变，还作为支撑结构对整个雾化模块在电子烟中起到支撑固定的作用。
纤维导液体20设有贯穿其相对两端的中心通道21，电热体10穿插并贴合在中心通道21内，与纤维导液体20充分稳定接触。电热体10的两个电极连接端12分别伸出纤维导液体20外，用于连接电源。支架体30套设在纤维导液体20外，与纤维导液体20卡接而相对固定。支架体30的整体长度大于纤维导液体20的长度，支架体30的相对两端分别伸长在纤维导液体20的相对两端外，这样当支架体30套设在纤维导液体20外时，可以将整个纤维导液体20容纳在其内部。
电热体10的设置形式可参考上述第一至第三实施例。
本实施例不同于上述第一至第四实施的是：纤维导液体20包括导液柱体210、分别连接在导液柱体210的相对两侧的两个导液侧部220；中心通道21设置在导液柱体210上。支架体30为筒状结构；对应纤维导液体20，支架体30上设有两个正对的开口33，支架体30套设在导液柱体210外，两个导液侧部220分别配合在对应的开口33内并伸出支架体30外，纤维导液体20以此和支架体30形成卡接，并且两个导液侧部220伸出支架体30外使得与烟液的接触面积更大，供液更充分。
具体地，本实施例中，支架体30具有相接的第一支架段310和第二支架段320。开口33设置在第一支架段310上，沿着第一支架段310延伸并贯穿第一支架段310的端面，这样可将第一支架段310分成两个间隔相对的支壁，纤维导液体20插接在两个支壁之间。
第一支架段310的整体长度大于纤维导液体20的长度，可使导液柱体210整体容纳在第一支架段310内，并且第一支架段310远离第二支架段320的端部还伸出在导液柱体210外侧。
纤维导液体20采用天然有机棉、合成纤维、无机纤维（如玻璃纤维等）、金属纤维（如不锈钢纤维等）中一种或多种制成。在制备方式上，纤维导液体20通过水刺、压制成型、模压成型、压注成型、注射成型、沉积等方式制成，无需粘结剂，只需要水和短纤维即可，保证口感纯净，成型温度为40℃-200℃，节能降耗。支架体30为硬质结构件，可以是不锈钢管、玻纤管、机加件、塑胶件或硅胶件。
纤维导液体20内还可根据需要也设有补气通道，具体可参考第三实施例。
本发明的一体式加热雾化模块，用于电子烟。装配时，以支架体30配合定位在电子烟的壳体内，无需以纤维导液体20或电热体10接触或配合在壳体内的基座上，从而避免了纤维导液体20和电热体10在装配过程中变形的问题，提供产品组装效率和良率。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
