[0039] 如图 7所示， 纤维格板 2的网孔的截面也可以为六边形。
[0040] 本发明的工作原理如下：
[0041] 水槽 1中装有水， 使纤维格板 2的顶部位于水面以上， 在浸润和毛细现象作用下 ， 纤维格板 2位于水面上方的部位变得湿润， 形成纤维格板 2的湿润部分； [0042] 通过带状风嘴 3向水槽 1的进气通道通入干燥空气， 干燥空气进入进气通道后， 在康达效应 (Coanda Effect)下， 大部分干燥空气 （90%以上的） 沿水槽内壁到达 水面， 受到水面的阻挡后沿水面进入纤维格板 2， 穿过纤维格板 2的湿润部分后 变成湿润空气从出气通道出来， 从而使空气湿度增加， 实现加湿的目的。
[0043] 如图 3所示， 带状风嘴 3包括彼此连通的进风道 31和出风道 32， 进风道 31与导风 板 4的出口相对应， 导风板 4的入口连接风机 5的出口；

[0047] 导风板 4的出口宽度大于入口宽度， 且导风板 4的出口宽度与带状风嘴 3的进风 道 31相匹配， 从而将来自于风机 5的气流沿带状风嘴 3的长度均匀分配。
[0048] 风机 5可以采用如图 2所示的离心风机， 离心风机设置于水槽 1的外部， 与水槽 1 内的水隔离幵， 从而保证风机 5的使用环境；
