请参考图1所示，一种加湿器，包括：相互密封装配的底壳1和水箱组件2，水箱组件2位于底壳1的上方，在水箱组件2的顶部上设有水雾喷盖5，水雾喷盖5上设有出雾孔52。水箱组件2内用于盛水，在底壳1上设有通风孔12，便于空气进入至底壳1内，实现空气流通。在底壳1上还设有控制开关，控制开关用于控制加湿器的启闭和调档。在水雾喷盖5的表面设有装饰压纹，装饰压纹可以是多个圆形或条形或波浪形。
如图2所示，在底壳1内设有水槽11，在水槽11底部设有雾化器13，在水槽11一侧设有风机(图中未示出)，在水槽11内还设有连通水箱组件2的控制水阀14，控制水阀14用于控制水箱组件2内的水流入至水槽11内，以便雾化器13将水雾化成水雾。
如图2所示，在本实施例中，水箱组件2包括：密封装配的水箱主壳21和水箱底板22，在水箱组件2内设有内中空的主出风管3，主出风管3贯穿水箱组件2并与出雾孔52连通，在水箱组件2上还设封雾盒4，封雾盒4设于水箱组件2和底壳1之间，封雾盒4具有封雾进风口41和封雾出风口42，封雾盒4内具有弯折的封雾风道43(图中箭头为风向)，封雾风道43连通封雾进风口41和封雾出风口42，封雾出风口42与主出风管3对接连通，封雾进风口41与水槽11连通，封雾进风口41可进风和进水雾。
如图1和图2所示，当雾化器13工作时，风机将外界空气通过通风孔12吸入至底壳1内，并形成风流，雾化器13将水槽11内的水雾化成水雾，水雾随风流经封雾进风口41进入至封雾盒4中，经弯折的封雾风道43改变风向，以降低风速，并经封雾出风口42进入至主风道内，然后经出雾孔52喷出。风流经过折弯的封雾风道43后，风速会很小，这时所产生的声音不会干扰人们的正常休息或工作，保证了人们的舒适感。
本发明提供的一种加湿器，仅通过封雾盒4内的折弯封雾风道43，就达到了降噪音的目的，且无需其他降噪结构，降低了成本和提高了材料利用率，同时减少结构便于生产组装和提高生产效率。
如图2所示，在本实施例中，封雾风道43包括：相互连通的缓冲腔431和导向腔432；其中，封雾进风口41连通缓冲腔431，封雾出风口42连通导向腔432，缓冲腔431和导向腔432内的风向呈台阶型变化。具体地，封雾盒4包括：圆形的缓冲筒和圆形的导向筒，缓冲筒内具有缓冲腔431，导向筒内具有导向腔432，缓冲筒的高度大于导向筒的高度，这样缓冲腔431与导向腔432呈L型，当风流由缓冲腔431进入至导向腔432内时，风流会改变一次风向，当风流由导向腔432进入至主风道内时，风流再一次改变风向，风流两次改变风向，有效地降低了风速，从而降低了风声以实现降噪的目的。
如图2所示，在封雾盒4远离封雾出口处的、位于导向腔432处的内侧壁设为导向曲面44。具体地，在导向筒的底部设置成导向曲面44，导向曲面44的作用是对风流进行导向引流，从而减少风流与导向筒内壁的对冲，有利于减少因风流对冲而产生的阻力噪音，同时导向曲面44使风流逐渐改变方向，过渡平滑。
如图2、图3和图4所示，在封雾盒4上还设有水雾进口45，水雾进口45的进雾方向与缓冲腔431的风向相同，水雾进口45靠近水槽11设置。具体地，水雾进口45位于雾化器的正上方，这样雾化器产生的水雾能尽快进入缓冲腔431内，有效避免水雾重进凝结成水。在本实施例中，封雾进风口41主要用于进风，还可进少部分水雾，封水雾进口45主要用于进水雾，还可进部分风。
如图3和图4所示，在本实施例中，封雾进风口41设置在封雾盒4的侧壁上。具体地，封雾进风口41设置在缓冲筒的侧壁，这样当风流经封雾进风口41进入至缓冲腔431内时，会改变一次风向，进一步地降低风速。在本实施例中，封雾进风口41靠近风机的出风端设置，在封雾盒4上还设有挡风板49，挡风板49用于将风机提供风力阻挡，以使风流进入至封雾进风口41处。
如图3、图4和图5所述，在本实施例中在，水箱底板22靠近底壳1的一侧上设有向上内凹的容置槽221，封雾盒4可拆卸式设于容置槽221内。封雾盒4可拆卸式安装，便于清理一些死角位置产生的水垢，有效保证喷雾器13内的洁净。
具体地，在容置槽221的内侧壁上设有径向内凸的凸板222，凸板222上设有定位孔223，封雾盒4的外壁上设有径向外凸的弹性板46，弹性板46上设有与定位孔223插接的定位柱47，封雾盒4在容置槽221内能相对旋转以使定位柱47脱离或插入至定位孔223中。
具体地，弹性板46大致为L型状，弹性板46一端设置在封雾盒4上，弹性板46的另一端为活动端，以便弹性板46发生形变，定位柱47设置在活动端上。具体地，容置槽221大致呈L型用于安装封雾盒4，其中，封雾盒4以缓冲筒为转轴进行旋转，当转配完成后，弹性板46位于凸板222的下方并使定位柱47插入至定位孔223中，当需要拆卸封雾盒4时，按压弹性板46以使定位柱47脱离定位孔223，然后以缓冲筒为转轴进行旋转，使弹性板46完全脱离凸板222即可将封雾盒4从容置槽221中取出，具有安装、拆卸方便的优点。其中，凸板222和弹性板46间隔设置有两个、三个或更多。
具体地，在封雾盒4上还设有径向外凸的、与弹性板46处于同一水平面的保护板48，保护板48具有开槽481，弹性板46部分容置在开槽481中并能 在开槽481中自由活动，保护板48可抵接在凸板222靠近所述容置槽221底部的一侧。弹性板46的活动端设置在开槽481中且能自由活动，开槽481的作用时使弹性板46能正常发生形变，保护板48用于防止弹性板46在正常安装好的情况下，直接向下(图2中是下方向)取出封雾盒4时而引起的变形，以保证封雾盒4安装的稳定性。当然，在其他实施了中，封雾盒4还可以采用锁螺丝的方式进行可拆卸式固定。
如图6和图7所示，在本实施例中，在出雾孔52下方的水雾喷盖5内设有挡雾板53。挡雾板53用于对风流进行阻挡，以改变风流的风向，进一步地降低因风速而带来的风声。在本实施例中，挡雾板53为半圆的平板，在其他实施例中，挡雾板53还可以设置成半圆的曲面板。
具体地，位于出雾孔52处的顶板51内侧设有凸出顶板51内侧表面的围板54。围板54同样用于对风流进入阻挡，以改变风流的风向，进一步地降低因风速而带来的风声。
对本实施例中的封雾盒4进行风速测试，在封雾盒4和通风孔12处的风速大致为2m/s时，进入至缓冲腔431内的风速为1.2m/s～1.6m/s，进入到导向腔432内的风速为0.6m/s～1.2m/s，通过主出风管3后从出雾孔52出来的风速小于0.4m/s，因此，通过封雾盒4后，风速有明显的降低，从而达到了降低噪音的目的。
本实施例的封雾盒4，通过缓冲腔431和导向腔432的两腔结构，缓冲腔431降低风速，导向腔432对风向进行导向、引流，明显地降低了风速；通过封雾盒4后不需单独增加其它的导向和引流装置，从而降低了成本低和提高了材料的利用率；封雾盒4的布局简单有序，利于加湿器的生产组装和生产效率的提高。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
