 本发明的最佳实施方式
实施例 1 ：
如图1-图4所示，本发明的具有外壳的一体式雾化芯，安装于雾化器的雾化座上（图中未示）。该雾化芯由外壳1、导液体2、发热丝3和电极引线4构成一体，外壳1设有上部开口11、下部开口12和中下部的侧壁通孔10。
导液体2套设于外壳1的内部中下段，侧壁通孔10被导液体2的外壁遮挡，导液体2设有竖直的中间通孔21与外壳的上部开口11和下部开口12连通，发热丝3设于导液体2上，发热丝3的两端设有电极引线4，电极引线4向下穿出于外壳的下部开口12。发热丝3由镍铬、或钨丝、或银合金、或铁铬铝等材料制成。在其它实施例中电极引线4 也可由设于发热丝两端的电极片或电极点替代，电极片或电极点用于和抵触式的弹性电极进行抵触连接。
发热丝3设于导液体2的下部表面或靠近下部表面的导液体内部，发热丝3以线条状的发热电阻均匀环绕导液体2的中间通孔21布设于同一平面内。外壳1 的内部位于导液体2 下面设有下部空腔用于构成雾化腔14，导液体2的中间通孔21和外壳1的内部位于导液体上面设有上部空腔13用于构成出雾通道。
外壳1由圆管构成，导液体2由圆柱体构成并套设于外壳1的内壁。外壳1由耐热金属材料制成，导液体2由多孔陶瓷材料制成。外壳1由金属材料制成，可以更好地保护由多孔陶瓷材料制成的导液体2，使导液体2在使用中不易发生碎裂。在其它实施例中，外壳1也可由耐热致密陶瓷材料制成。
外壳1、导液体2、发热丝3和电极引线4的材料置于模具内成型后一体烧结制成，这样雾化芯成型为一体，并自带有雾化腔，在装配到雾化器上时，上部只需连接到吸嘴，而下部只需安装到雾化座上，使得零配件减少，安装简单，有利于实现自动化生产。另外，本发明的雾化芯，在装配到雾化器上后，雾化芯的外壳1直接置于雾化器的储液腔内，与储液腔内的待雾化液直接接触。而雾化芯的外壳1 由金属材料制成，使得发热丝3 工作时，其多余的热量可很快通过导液体2传导至外壳1，而外壳1可将热量传导给待雾化液，这样可在使用中很快加热待雾化液，使其流动性增加，因此本发明的雾化芯可以使用粘稠度较大的待雾化液。
