技术领域
本公开涉及冷风扇技术领域，尤其涉及一种机头及冷风扇。
背景技术
冷风扇利用水的蒸发吸热吹出冷风，湿帘是冷风扇中的重要组成部件，可以增加水与空气的接触面积和时间，使水吸热蒸发，有效降温。通常情况下，一般湿帘设置在湿帘支架上，湿帘支架固定在风扇后壳或格栅处，湿帘则随风扇摇头而转动。
随着冷风扇的广泛应用，循环风扇应运而生，循环风扇除了左右摇头之外，还可实现上下摇头。湿帘若处于竖直状态，上下摇头的风扇的出风方向不能垂直于湿帘，大减少了水与空气的接触面积和时间，降温效果大大降低。在冬天的寒冷季节中，空气干燥，若开启冷风扇加湿，在风吹下会感到寒冷。

在一些实施方式中，湿帘组件的轴心线与机头的轴心线之间的夹角在120°-150°的范围内取值。
在一些实施方式中，湿帘组件与机头的轴心线之间的夹角为135°。
在一些实施方式中，壳体包括卡接固定的前壳和后壳，前壳呈圆筒状，前壳的端部设置出风栅，出风栅为风道的进风口，前壳的轴心线呈水平方向分布，后壳呈朝向前壳开口的半球面状，后壳上设有风道的进风口。
在一些实施方式中，湿帘组件包括湿帘本体和湿帘支架，湿帘本体固定在湿帘支架内，湿帘支架可拆卸的固定在后壳内。
在一些实施方式中，湿帘支架本体上设有卡扣，后壳的内壁上设有固定架，固定架上设置与卡扣配合的卡槽，卡扣卡接在卡槽内。
在一些实施方式中，湿帘支架为长方体框架，湿帘支架顶面设有进水口，湿帘支架底部设有用于支撑湿帘本体的支撑台，支撑台下方设有回流通道，回流通道的底面为朝向湿帘本体下游方向倾斜的导流斜面。
在一些实施方式中，湿帘本体上游方向的回流通道端部设有回流口。
在一些实施方式中，风机组件设置在湿帘组件和风道出风口之间，风机组件包括电机，电机固定在电机支架上，电机支架固定在后壳的开口处，电机的轴心线与前壳的轴心线重合，电机的驱动轴上设有风叶。

具体实施方式
为了更好地了解本公开的目的、结构及功能，下面结合附图，对本公开的一种机头及冷风扇做进一步详细的描述。
如图1所示，本公开的机头，包括具有风道的壳体，风道的进风口和出风口分别设置在壳体相对的侧壁上，沿空气流通方向，风道内设有湿帘组件和风机组件5，湿帘组件固定在壳体的内壁上，湿帘组件相对风道的轴心线倾斜设置，以确保壳体上下摇头时，湿帘组件在任意角度均被浸湿，并与空气接触，实现送风降温的目的。
壳体包括卡接固定的前壳2和后壳1，前壳2呈圆筒状，前壳2的端部设置出风栅21，出风栅21为风道的进风口，前壳2的轴心线呈水平方向分布，后壳1呈朝向前壳2开口的半球面状，后壳1上设有风道的进风口。
湿帘组件作为冷风扇的关键部件，通常的，湿帘组件包括湿帘本体4和湿帘支架3，湿帘本体4固定在湿帘支架3内，为了使湿帘组件固定在壳体内，湿帘支架3本体上设有卡扣，后壳1的内壁上设有固定架，固定架上设置与卡扣配合的卡槽，卡扣卡接在卡槽内，从而使湿帘组件可拆卸的固定在壳体内，使放置空间最大利用化。
通常的，机头在上下摇头时，从机头的轴心线处于水平状态，一直到机头的轴心线处于竖直状体，如图1所示，机头的轴心线处于水平状态，如图3所示，机头的轴心线处于竖直状态。在机头上下摇头过程中，为了保证机头在任意角度，湿帘均可被浸湿，湿帘组件的轴心线与机头的轴心线之间的夹角为钝角。
通常的，湿帘本体4对水具有很强的附着力，湿帘本体4在与竖直方向的夹角小于70°的范围内，湿帘本体4内的水均不会脱离湿帘本体4，为了保证湿帘本体4的浸湿效果，湿帘组件的轴心线与机头的轴心线之间的夹角在120°-150°的范围内取值。在一些实施方式中，湿帘组件与机头的轴心线之间的夹角为135°。
如图1所示，当机头上下摇头时，湿帘本体4因固定在后壳1内，在机 头摇头过程中，湿帘本体4也随机头上下摆动，机头水平出风时，湿帘支架3与水平方向呈45°；机头向斜向上与水平面呈45°时，湿帘本体4垂直水平面，如图2，机头斜向上出风；如图3所示，机头继续向斜向上摇头至与水平面呈90°时，湿帘本体4转动90°，此时，湿帘本体4与水平面也呈45°。机头在上下摇头的过程中，湿帘本体4与水平面之间的夹角始终小于70°，有效保证湿帘本体4内的水不会脱离。
如图4所示，湿帘支架3为长方体框架，湿帘支架3的端面上分别设置固定湿帘本体4的第一限位块32和第二限位块33，湿帘支架3顶面设有进水口31，湿帘支架3底部设有用于支撑湿帘本体4的支撑台34，支撑台34下方设有回流通道35，水槽内的水经进水口31滴落至湿帘本体4上，浸湿湿帘本体4后，流至回流通道35内，回流通道35的底面为朝向湿帘本体4下游方向倾斜的导流斜面。为了保证湿帘本体4在机头转至竖直向上吹风时，水能顺畅排出回流通道35，湿帘本体4上游方向的回流通道35端部设有回流口36，湿帘支架3可双向排水，当在干燥寒冷的天气需要单独加湿时，机头可竖直向上送风且开启加湿功能，达到加湿的功能又不使人降温，达到仅加湿而不降温的集成效果。
风机组件5设置在湿帘组件和风道出风口之间，风机组件5包括电机51，电机51固定在电机支架53上，电机支架53固定在后壳1的开口处，电机51的轴心线与前壳2的轴心线重合，电机51的驱动轴上设有风叶52。
本公开还提供了一种冷风扇，包括机座6和上述的机头，机座6上设有摇头组件，机头固定在摇头组件上。
该机头的湿帘组件相对风道的轴心线倾斜设置，使机头摇头过程中，保证机头在任意角度时，水流均可流经湿帘，并与空气接触，达到送风降温的目的，用户体验佳；同时，湿帘支架3采用双向排水，无论机头处于何种角度，湿帘本体4的排水顺畅，在干燥、寒冷的季节，机头竖直向上送风，加湿空气，不会造成用户周围空气降温，达到仅加湿而不降温的效果。
可以理解，本公开是通过一些实施例进行描述的，本领域技术人员知悉的，在不脱离本公开的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等效替换。另外，在本公开的教导下，可以对这些特征和实施例 进行修改以适应具体的情况及材料而不会脱离本公开的精神和范围。因此，本公开不受此处所公开的具体实施例的限制，所有落入本公开的权利要求范围内的实施例都属于本公开所保护的范围内。
