Description

一种加湿器 技术领域
本发明涉及加湿器技术领域，尤其涉及一种加湿器。

随着生活条件的改善，人们对居住环境的舒适度要求越来越高。其中空气湿度是影响舒适度的重要因素之一，尤其是在天气比较干燥的地区或季节。因此市场对加湿器的需求越来越大，逐渐成为品质生活的必备小家电之一。
目前市场上的加湿器大多采用需要从下面加水的负压水箱，这种结构的加湿器结构复杂，操作繁琐，使用和维护都非常不方便。因此一些厂家开始研发采用开放式水箱的上加水加湿器，主要有浮球式(申请号2018105550773)的和电磁阀式(申请号2017100738283)。
现有技术中的浮球式和电磁阀式的加湿器一般采用和传统负压水箱一样的分体式结构，即加湿器的水箱和底座是分离的，水箱的位置导致加湿器的重心较高，使用容易倾倒，且水箱与底座之间需要设置雾化组件，水箱与底座无法形成一体化设计，产品结构复杂，开模成本较高；在水箱中下部或者底部设置可控止水阀，在底座上部设置有雾化水槽，雾化器设置在雾化水槽底部的内侧空间中，加湿所用的水储存在水箱中，水在重力作用下，通过水箱上的止水阀可控的流入到水箱下面的雾化水槽中；水在水槽中被雾化器雾化后，经由出雾通道扩散到空气中完成加湿过程。该类产品依靠止水阀控制雾化水槽中的水位高度，一旦止水阀出现故障，水箱中的水有可能源源不断的向雾化水槽中泄放，导致水槽中的水位超过安全水位，溢流到机器内部或者台面及地板上，造成机器短路甚至烧毁，严重的更有可能导致触 电及火灾等重大安全事故。
发明内容
本发明的目的是提供解决现有技术中使用稳定性较低、容易漏水的缺陷，同时降低成本，有助于提高使用安全性的一种加湿器。

可选的，所述雾化舱在溢流板一侧设有挡板，所述挡板与溢流板之间形成溢流通道，所述挡板一端贴近所述水箱侧壁。可选的，还包括用于将雾化舱中溢出的水回流到水箱的导流件，所述导流件一端与雾化舱连接、另一端延伸到水箱内。
可选的，所述导流件为导流板，所述导流板设有与竖直方向呈预设角度的导流斜面，所述导流斜面向偏离溢流板方向倾斜。
可选的，所述导流件为导流板，所述导流板表面设有若干用于减缓水流速度的凸起的导向筋和/或凹陷的导向槽。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例1：
参考图1和图6，本实施例提供了一种加湿器，加湿器包括：
水箱1，水箱1上端设有用于向水箱1内加水的加水口11；
雾化舱2，雾化舱2设置于水箱1上部，雾化舱2设有用于使雾化舱2中的水位超出预设水位时溢出到水箱1的溢流板；其中，雾化舱2设有雾化出口设置于雾化舱2顶部的雾化通道22；
泵水组件3，泵水组件3的进水端与水箱1连通、出水端与雾化舱2连通。第一，本实用新型在水箱1上端设置加水口11，可以直接从水箱1上端向水箱1内加水，使用方便；第二，雾化舱2设置于 水箱1上部，使水箱1在加湿器中的位置较为靠下，降低加湿器的重心，使加湿器不容易倾倒，使水箱1在加湿器整体结构设计中与底座可呈一体化结构，水箱1与底座之间无需设置雾化组件，增强产品的整体性，简化加工工序，减少模具投入；第三，通过泵水组件3将水箱1中的水输送到雾化舱2中，在雾化舱2中设有溢流板21，溢流板21在雾化舱2内形成用于存储雾化的预设的水量的水槽，使雾化舱中的水位保持在预设的水位高度，多余的水从溢流板21上溢出到水箱1，避免水位过高造成水从进风口28溢出造成电器损坏，提高使用的安全性。
本实施例的泵水组件3通过进水管534将水箱1中的水输送到流动腔中，进水管534可设置在水箱1内或水箱1外侧，当进水管534在水箱1内时，即使进水管534有泄露，水也会自动流回水箱1，不会造成漏水；进一步的，水箱1设有叶轮腔，泵水组件3为水泵，水泵的叶轮安装于叶轮腔内，叶轮的转轴与水泵驱动单元连接，一方面，减少与水泵连接的管接头数量，减少管路漏水隐患，降低成本；另一方面，将水泵的驱动单元与叶轮腔分离，有利于提升水泵的安全性，也提升了水泵的可维护性，更换水泵时只需要更换驱动单元即可，无需拆卸与叶轮腔连接的管路部分；可以理解的是，叶轮腔可与水箱一体成型，降低生产成本，更加简洁可靠。
进一步的，雾化舱2在溢流板一侧设有挡板24，挡板24与溢流板之间形成溢流通道25，使水从溢流通道25中定向溢出回到水箱1，使用更稳定，另外，挡板24一端贴近水箱1侧壁，使溢出的水可以沿着水箱1的侧壁回流，减少水流直接从空中落入水箱1造成的噪音，进一步提高了用户的使用体验。
本实施例的雾化舱2底部设有雾化组件4，雾化舱2底部对应雾化组件4设置有第一引流板26，雾化舱2底部设有与第一引流板26 对应的第二引流板27，第一引流板26设置于第二引流板27内侧且与第二引流板27交错布置，雾化通道22设置于第二引流板27外侧，当雾化组件4对雾化舱2中的水进行雾化时，雾化产生的水雾在第一引流板26的引流作用下向雾化舱2顶部流动，同时，当顶部的水雾累计到预设量且继续增加时，增加的水雾量从第二引流板27稳定、均匀溢出后从雾化通道22喷出，由于雾化组件4雾化产生的水雾量不均匀，避免雾化产生的不均匀的水雾直接从雾化通道22中喷出，从而保持了从雾化通道22中喷出的水雾的质量和均匀度；另外，当大颗粒水雾遇到第一引流板26时，容易粘附在第一引流板26回流到雾化舱2内，防止大颗粒水雾从雾化通道22直接喷出。
进一步的，本实施例还包括风机6，雾化舱2设置有进风口28，风机6的出风口依次与雾化舱2的进风口28和雾化通道22连通，使雾化舱2中雾化形成的水雾通过风机6形成的气流从雾化通道22中定向吹出，提高使用的稳定性。
进一步的，本实施例还包括用于将雾化舱2中溢出的水回流到水箱1的导流件5，导流件5一端与雾化舱2连接、另一端延伸到水箱1内，降低回流的噪音，可以理解的是，本实施例使水箱1的侧壁与溢流通道25连接，从而使溢出的水沿着水箱1侧壁回流，水箱1侧壁形成导流件5，简化加湿器的结构，降低生产成本。
实施例2：
参考图2和图3，较佳的，本实施例提供了一种加湿器，与实施例1的区别在于，在本实施例中，雾化舱2设有隔流板23，隔流板23使雾化舱2形成雾化腔和流动腔，溢流板设置于流动腔，泵水组件3的出水端与流动腔连通，隔流板23下部开设有用于水在雾化腔与流动腔之间流通的隔流孔231，使泵水组件3输送到雾化舱2中水先进入流动腔，流动腔中的水从隔流孔231中缓慢进入雾化腔中，一 方面，防止泵水组件3输送的水过多导致来不及溢流，雾化腔中的水位过高发生安全事故，另一方面，避免泵水组件3输送的水直接进入雾化腔中与水雾化流动碰撞产生更大的噪音，从而降低使用时产生的噪音，提高使用体验。
实施例3：
参考图4，本实施例与上一实施例的区别在于，本实施例的导流件5为导流管，导流管一端与雾化舱2连接、另一端连接到水箱1底部，使雾化舱2溢出的水流回到水箱1中且避免直接落入水箱1产生噪音，可以理解的是，导流管可设置于水箱1内，当导流管设置于水箱1内时，即使导流管破损，导流管内的水也可以直接流回到水箱1，避免水溢出到外界，使用安全性更高。
实施例4：
参考图5和图6，本实施例与上一实施例的区别在于，本实施例中的导流件5为导流板，导流板设有与竖直方向呈预设角度的导流斜面51，导流斜面51向偏离溢流板方向倾斜，使雾化舱2中的水溢出后从导流斜面51中流向水箱1，从而减缓溢出的水流向水箱1的速度，降低水流入水箱1产生的噪音，提高用户体验。
实施例5：
参考图7和图8，本实施例与实施例3的区别在于，本实施例的导流件5为导流板，导流板表面设有若干凸起的导向筋52，使雾化舱2中的水溢出后从导流板表面流向水箱1，当水经过凸起的导向筋52时，水流的速度有所降低，从而减小了水从雾化舱2流向水箱1的噪音。
实施例6：
参考图9～图11，本实施例与上一实施例的区别在于，导流件5 包括外壳53，外壳53内形成有导流腔531，导流腔531内设有若干依次交叠的导流片532，使水从雾化舱2流向水箱1时，水在导流片532之间流动，从而减缓水流的速度，降低噪音；进一步的，导流腔531包括第一侧壁以及与第一侧壁相对的第二侧壁，导流片532一端分别连接于第一侧壁和第二侧壁且向下倾斜设置。
其中，导流片532与水流接触的表面凸起形成缓冲弧形面533，进一步使水经过缓冲弧形面533时降低流动速度，降低噪音；可以理解的是，导流片532与水流接触的表面凹陷形成缓冲弧形面533，实现降低水流动的速度。
另外，本实施例的导流件5设有进水管534，进水管534一端与泵水组件3的出水口连通、另一端与雾化舱2连通，通过导流件5实现水箱1中的水流入雾化舱2以及从雾化舱2中回流到水箱1，简化加湿器结构。
综上，第一，本发明在水箱1上端设置加水口11，可以直接从水箱1上端向水箱1内加水，使用方便；第二，雾化舱2设置于水箱1上部，通过泵水组件3将水箱1中的水输送到雾化舱2中，在雾化舱2中设有溢流板，溢流板在雾化舱2内形成用于存储雾化的预设的水量的水槽，使雾化舱2中的水位保持在预设的水位高度，多余的水从溢流板上溢出到水箱1，避免水位过高造成水从雾化通道22溢出造成电器损坏，提高使用的安全性；第三，设置有导流件5，减小水从溢流板上溢出后回到水箱1时形成的噪音；第四，泵水组件3通过进水管534将水箱1的水输送到雾化舱2中，通过将进水管534设置在水箱1内，使进水管534即使破损后水流出也能回流到水箱1，避免水流到外界形成安全隐患。
