Description

一种防漏水的上加水加湿器 技术领域
本实用新型涉及一种防漏水的上加水加湿器，适用于家用电器的技术领域。
背景技术
随着生活条件的改善人们对居住环境的舒适度要求也越来越高，空气湿度是影响舒适度的重要因素之一，特别是冬天的北方地区和长期使用空调的场所空气湿度比较低，因而加湿器也成为人们生活中必不可少的电器。
目前，现有的加湿器一般采用加湿器壳体与储水箱结合设置或加湿器壳体与储水箱分离设置。当采用加湿器壳体与储水箱结合设置的方式时，即将加湿器壳体形成的腔体作为储水腔，这种结构的弊端较为明显：储水箱不能从加湿器中取出，不利于加湿器的维修、清洁；而且这种结构设计必然导致使用者需要搬动加湿器的整体来完成蓄水动作，或者移动给水直接向加湿器壳体内蓄水，操作不便，尤其，对于老年人或者小孩容易造成安全隐患。当采用加湿器壳体与储水箱分离设置的方式时，水箱设置在高位，下水口在水箱下端，在下水口设置水位控制装置，水位控制装置结构简单，或有杂物误入易失效，使水外流溢出，加湿器一般放置在电源不远处，易产生危险；针对这种情况，也有采取水箱和壳体进行密封连接的技术方案，但对水箱和壳体配合的精度要求高，密封范围大，水箱分离盛水和安装不方便。

其中，所述驱动机构包括设置在水槽内的浮球、限位架和控制臂，所述控制臂与所述浮球之间形成杠杆，，浮球受水槽内水位控制升降，带动控制臂驱动水阀机构的打开或关闭。
其中，所述水阀机构包括管状阀座，所述阀座上部与所述下水口连通，下部与所述过水口连通，所述阀座与所述下水口和所述过水口之间均设置有密封圈；所述水阀机构还包括设置在下水口内的第一阀体和第一阀芯以及设置在所述阀座内的第二阀体和第二阀芯，所述第二阀芯底面与所述控制臂上端面动作范围内接触设置，所述第一阀芯底面与所述第二阀芯的顶端动作范围内接触设置，所述第一阀芯控制所述第一阀体对所述下水口进行开关，所述第二阀芯控制所述第二阀体对所述阀座进行开关。

如图14-15所示，所述水阀机构4可设置为第三种结构，包括设置在下水口31内的第一阀体411和第一阀芯421，还包括设置在所述过水口24内的第二阀体412和第二阀芯422，所述第二阀芯422底面与所述控制臂53上端面动作范围内接触设置，所述第一阀芯421底面与所述第二阀芯422的顶端动作范围内接触设置，所述第一阀芯421控制所述第一阀体411对所述下水口31进行开关，所述第二阀芯422控制所述第二阀体412对所述过水口24进行开关。本结构相对第二种水阀机构省去了阀座，安装更加简单。
优选地，所述雾化器包括加热装置16和超声雾化装置14，使用时可以选用单超声雾化的、单加热雾化的或超声及加热混合雾化的几种方式。进一步地，水槽12内还包括有加热水槽121，所述加热水槽121与所述下水槽12连通。所述加热器设置在所述加热水槽121内，所述加热水槽121上设置有热蒸汽管道，所述热蒸汽管道一端与所述加热水槽121的槽口连通，另一端与所述出雾管道连通。用于对水槽内的水和喷出的蒸汽进行加热，可在冬天等需要的天气对喷出的雾进行加热。
尽管上述已经描述了本实用新型的实施例，但对于本领域普通技术人员而言，可以理解为在不脱离本实用新型的原理和精神的情况下可以对上述实施例进行变换，本实用新型的保护范围由所述权利要求及其等同物限定。
