参阅图1，图1示出了本申请一实施例中的湿帘组件的结构示意图。本申请一实施例提供的加湿器(图未示)，包括风道组件、湿帘组件100、水泵等部件，湿帘组件100设置于风道组件的出风口，水泵与湿帘组件100连接用于为湿帘组件100供水。
如此，在加湿器的工作过程中，水泵将水箱里的水抽到湿帘组件100中，风道组件产生的气流进入位于其出口的湿帘组件100，携带从湿帘组件100上蒸发的水分后湿帘60流出，从而有助于提高环境的湿度。
需要说明的是，风道组件、水泵等部件的具体构造不属于本申请的主要发明点，故不在此赘述，可根据需要选用不同构造的风道组件和水泵。
请继续参阅图1，湿帘组件100包括湿帘底座20、布液单元40以及湿帘60。湿帘底座20呈中空的壳体状结构，包括底座底壁及自底座底壁的边缘朝同一方向延伸形成的底座侧壁。在下列实施例中，定义湿帘底座20的高度方向为第一方向(即图1中的Z方向)，湿帘底座20的长度方向为第二方向(即图1中的X方向)，湿帘底座20的宽度方向为第三方向(即图1中的Y方向)，第一方向、第二方向以及第三方向两两相交，作为一较佳的实施方式，第一方向、第二方向以及第三方向两两垂直。
进一步地，底座侧壁在第三方向上的一侧开设与外部环境连通的蒸发口21，底座侧壁在第二方向上的一侧开设有连通蒸发口21的插入口，湿帘60可通过插入口安装于湿帘底座20中，并通过蒸发口21暴露于外部环境中，风道组件形成的气流可从蒸发口21流过。
布液单元40安装于湿帘底座20在第一方向上远离湿帘60底壁的一端而位于湿帘底座20的顶部，湿帘底座20与布液单元40之间界定形成用于容纳湿帘60的安装腔。布液单元40背向底座底壁的一侧表面形成具有槽底壁的安装槽41，安装槽41的槽底壁在第三方向上远离安装口的一侧开设有注水孔412，安装槽41的槽底壁在第三方向上靠近安装口的一侧开设有多个下水孔414，所有下水孔414间隔排布，水泵可通过注水孔412将水注入安装槽41中，安装槽41中的水通过下水孔414流出。
湿帘60大致呈长方体状结构，自湿帘底座20的插入口沿第二方向插设于湿帘底座20而位于安装腔中，湿帘60的长度方向沿第二方向延伸，湿帘60的高度方向沿第一方向延伸，湿帘60的厚度方向沿第三方向延伸。湿帘60在第一方向上位于布液单元40的一侧并连通布液单元40的下水孔414，因此从下水孔414流出的水流入湿帘60进行布液。
在加湿器工作过程中，湿帘60在第一方向上连通下水孔414的一端承接水体，水扩散传播至整个湿帘60，从而提高了水分的蒸发效率，增强了加湿效果。其中，水体既可沿湿帘60内部的毛细孔等间隙传输，也可沿湿帘60表面在重力作用下流动传输。
正如背景技术中所述，现有的湿帘60容易出现润湿不均的现象，从而影 响了湿帘组件100的加湿量，进而影响了加湿器的使用体验。申请人通过研究发现，造成上述问题的主要原因在于，现有的布液单元40上的下水孔414通常为直径较小的圆形，在安装槽41中的水通过下水孔414流入湿帘60的过程中，容易产生表面张力，使水形成液封堵住下水孔414，进而导致下水不均匀的现象，最终导致湿帘60出现润湿不均匀现象。
基于上述问题，请参阅图2所示，图2示出了本申请一实施例中的布液单元的仰视图。本申请中的布液单元40上开设的下水孔414为带有棱角的多边形，相较于现有技术中的圆形小孔，可以有效减少下水孔414出现液封现象的情况，使安装槽41中的水可通过各个下水孔414顺利流出，保证布液单元40中的水可均匀、顺畅地流入湿帘60，有效防止湿帘60出现润湿不均匀的现象，进而保证良好的加湿效果，提高了设有该湿帘组件100的加湿器的使用体验。
在一些实施例中，在前述湿帘组件的基础上，下水孔414的内径不小于2.5mm，从而进一步减少下水孔414出现液封现象的情况，使安装槽41中的水可通过各个下水孔414顺利流出。
在一些实施例中，在前述湿帘组件的基础上，下水孔414为矩形。可以理解，下水孔414的形状不限于此，在其他一些实施例中，下水孔414可呈正方形、五边形、六边形等规则或不规则形状。可以理解，各个下水孔414的形状和尺寸可以相同也可以不同，可以根据下水孔414的位置和下水速度需要，将不同位置的下水孔414设置为不同的形状和尺寸，从而满足不同需要，实现更好的浸润效果。
在一些实施例中，在前述湿帘组件的基础上，所有下水孔414沿第二方向间隔排布，相邻两个下水孔414的孔距d为4mm-11mm。具体地，如果相邻两个下水孔414的孔距过大，会造成湿帘60对应于两个下水孔414之间的某些位置不能被润湿，而如果相邻两个下水孔414的孔距过小，则会导致流入湿帘60的水流量过大、水流过多，造成水泵供电浪费、水流浪费，进而导致成本增加、资源浪费等负面影响。因此，将相邻两个下水孔414的孔距d设置为4mm-11mm，可保证湿帘60各处被均匀润湿的同时有效减少资源的浪费，降低了加湿器的使用成本。
可以理解，下水孔414的排布方式不限，可根据安装槽41的形状、其他 部件的设置进行等因素进行调整，从而满足不同情况下下液要求。具体在一实施例中，布液单元40上开设有三组下水孔414，三组下水孔414沿第二方向依次排布，且位于中间的一组下水孔414在第三方向上与其他两组下水孔414错位设置以避让其他结构。
申请人在研究过程中发现，当沿第二方向将湿帘60自插入口插入安装腔时，由于安装腔在第一方向上的高度与湿帘60在第一方向上的高度几乎相同，因此湿帘60容易被布液单元40干涉而无法顺畅地插入安装腔中。
基于上述问题，在前述湿帘组件的基础上，本申请的布液单元40朝向湿帘60的一侧表面凸设有导向筋条416，导向筋条416的一端连接最靠近插入口的下水孔414的边缘，导向筋条416的另一端沿第二方向延伸朝插入口延伸。如此，布液单元40通过沿第二方向延伸的导向筋条416接触湿帘60而对湿帘60起到导向作用，使湿帘60可顺畅地装配至容纳腔中。
在一些实施例中，布液单元40朝向湿帘60的一侧表面凸设有分别围绕每个下水孔414的引导边，从下水孔414流出的水在引导边的引导下进入湿帘60中。但另一方面，当沿第二方向将湿帘60自插入口插入安装腔时，由于凸出的引导边的存在，湿帘60可能卡入相邻两个引导边之间的间隙中。
因此，本申请中的布液单元40朝向湿帘60的一侧表面凸设有限位筋条418，每条限位筋条418连接于相邻两个下水孔414的引导边之间，且每条限位筋条418沿第二方向延伸，从而可防止湿帘60在插入安装腔的过程中被凸出的引导边干涉，使湿帘60可更加顺畅地进入安装腔中。
作为一较佳的实施方式，引导边凸出于布液单元40的表面的高度略高于导向筋条416和限位筋条418凸出于布液单元40的表面的高度，从而在起到导向、防止干涉的作用的同时，不影响引导边的引导功能。在其他一些实施例中，引导边也可与导向筋条416和限位筋条418齐平。
结合图3、图4及图5所示，图3示出了本申请一实施例中的湿帘的侧视图，图4示出了本申请一实施例的湿帘的俯视图，图5示出了本申请一实施例的湿帘的正视图。
在一些实施例中，湿帘60包括湿帘本体61，湿帘本体61呈由纤维纸折叠形成的长方体状叠合结构，纤维纸折叠得到的湿帘本体61包括多个叠片，所有叠片沿第二方向首尾依次相接，相邻叠片之间形成沿第一方向延伸的折 痕，相邻两片叠片之间的间距(即折距)L为3mm-5mm。
湿帘本体61在第一方向上的整体长度相同的情况下，相邻两片叠片之间的最大间距过大或过小，均会影响加湿器的加湿量，本申请的叠片的相邻两片叠片之间的间距L为3mm-5mm，可使加湿器的加湿量处在最佳范围内。
在一些实施例中，相较于采用无纺布等材料形成湿帘本体61，本申请中的湿帘本体61由纤维纸形成，纤维纸相对无纺布等材料来说，具有重量更轻、价格更低、干燥速度更快的特点，长时间使用也不易滋生细菌，从而在一定程度上缓解湿帘本体61发霉发臭的问题，延长湿帘60的使用寿命。
在一些实施例中，每片叠片开设有多个间隔排布的水刺孔612，每个水刺孔612的直径为1.5mm-2mm的类圆形孔，风道组件产生的气流可通过水刺孔612穿过湿帘60。反之，如果水刺孔612的直径过小，则容易产生液封现象阻挡气流流过，如果水刺孔612的直径过大，则导致湿帘本体61的有效蒸发面积过小，影响了水分的蒸发效果，进而影响加湿器的加湿效果。
在一些实施例中，湿帘60还包括至少两条形成于湿帘本体61上的固定筋条63，所有固定筋条63沿第一方向间隔排布，每条固定筋条63沿第二方向自湿帘本体61的一侧延伸至另一侧，从而起到固定间距、支撑湿帘本体61的形状的作用。具体在一些实施例中，固定筋条63通过在湿帘本体61的表面打胶形成。
在一些实施例中，相邻两条固定筋条63之间的间距H为25.4mm或50.8mm，优选为25.4mm。在现有认知中，由于固定筋条63形成于湿帘本体61的表面，会对湿帘本体61上的水分的流动形成阻碍，因此湿帘60上的固定筋条63的数量越少，湿帘60的吸水面积、过风面积越大，从而可以增加湿帘60的加湿量。然而，申请人在研究过程中发现，适当增加固定筋条63的数量，可使湿帘本体61的固定更加牢固，叠片之间的折距更加均匀，反而提高了湿帘60的整体加湿量。因此，相邻两条固定筋条63之间的间距H为25.4mm或50.8mm，而不同于现有技术中相邻两条固定筋条63之间的间距为101.6mm。
在一些实施例中，湿帘60还包括上水端件和下水端件(图未示)，上水端件和下水端件分别在第一方向上固接于湿帘本体61的上下两端，上水端件和下水端件均由吸水材料(例如针刺棉)制成，具有优良的吸水能力。
如此，从下水孔414流出的水可先通过上水端件吸收，然后传递至湿帘本体61，充分润湿湿帘本体61后，到达下水端件的水分被下水端件吸收排出。在上水端件的缓冲下，布液的水分会更加稳定、均匀地向整个湿帘本体61传递，可有效避免水流集中、不稳定导致水流过大活短时积水过多。而且，在润湿湿帘本体61后，多余的水分被整个下水端件吸收并排出，从而可避免水分堆积，进而防止飞水。
在另一些实施例中，基于由纤维纸形成的湿帘本体61具有良好的浸润性能，湿帘60也可不设置上水端件和下水端件，湿帘本体61直接与布液单元40接触，下水孔414流出的水可直接进入湿帘本体61中，从而简化了湿帘60的构造，进一步降低了湿帘60的生产成本，同时也不易发霉发臭。
上述湿帘组件100及设有其的加湿器，布液单元40中的水可通过特殊设计的下水孔414流入湿帘60，配合湿帘本体61的水刺孔612的孔径、折距以及固定筋条63的间距设计，湿帘60可充分润湿，有效提升了加湿量。而且，导向筋条416、限位筋条418的设置提高了湿帘60的安装顺畅度。此外，由纤维纸形成的湿帘本体61在显著降低成本的同时，有效缓解了湿帘本体61因长期处于湿润状态而发霉发臭的问题，最终改善了加湿器的使用体验。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
