水过滤集尘装置及其水过滤吸尘器 技术领域
本发明属于清洁设备技术领域， 涉及一种水过滤集尘装置及其水过滤吸尘器。 背景技术
吸尘器利用其内置的电动机驱动风机而产生负压进行除尘， 它在操作使用时不会 灰尘飞扬， 并能吸除缝隙中及地毯上一般不易清除的尘屑， 使用方便、 操作简单， 被 广泛用于家庭和公共场所中。
随着人们生活水平的日益提高， 对环保的意识也在逐渐增强， 人们对于吸尘器的 要求除了能满足有效吸尘的功能之外， 还会考虑到使用寿命、 噪声、 集尘效率等综合 因素。 由此， 吸尘器应运而生得到了人们的普遍认可。
水过滤吸尘器中的集尘桶一般包括入气口、 水过滤筒、 过滤器、 出气口， 包含灰 尘的气体从入气口通过气流管道进入水中， 水过滤筒里的水溶解大部分灰尘， 然后， 气体再经过滤器进一步过滤， 从出气口出去洁净的空气。
在现有的水过滤吸尘器中， 含尘气体是从入气口通过气流管道直接进入水过滤筒 的底部进行过滤分离。 如中国公开专利 CN201987463Y中水过滤吸尘器所揭露， 由于 进入水中的含尘气流为高速气流， 其在水面上会产生大量气泡且使得水面产生剧烈翻 滚， 大量气泡裹带着灰尘一起上升进入到过滤海绵， 过滤棉随着接收的灰尘增多， 逐 渐被污染和堵塞， 造成大量的吸力损失并降低了过滤效果。
因此， 现有水过滤吸尘器主要存在以下问题： 一、 过滤海绵被污染或堵塞， 造成 吸力损失。 随着含尘气体进入过滤筒的水里再向上走时， 气体或气泡容易裹带灰尘进 入过滤海绵， 从而造成过滤海绵的污染和堵塞； 二、 水过滤筒中水量逐渐减少， 过滤 效率降低。 随着含尘气流或气泡携带的水分进入过滤海绵， 水过滤筒中的水量逐渐减 少， 其对应溶解灰尘的能力对应降低， 造成水过滤分离效率的降低。 三、 易导致损坏 电机等电器件。 由于气体先通入水中， 气流上升过称中仍携带一些水分， 其通过过滤 海绵等过滤后， 最终， 气流仍会携带一些水分进入电机， 造成电路板短路等状况而损 坏电机等电器件。 发明内容 本发明所要解决的技术问题在于针对现有技术的不足， 提供一种水过滤集尘装置 及其水过滤吸尘器， 提高分离效率， 并且延长电器件的使用寿命。
本发明所要解决的技术问题是通过如下技术方案实现的：

本发明水过滤集尘装置包括具有储水功能的水过滤筒 23， 该水过滤筒 23上设置 有进气口和出气口，含尘气流通过所述进气口沿水过滤筒 23的筒壁旋转向下进入储水 区域， 所述筒壁设有压水机构， 该压水机构位于进气口、 出气口的下方。
储水区域位于水过滤筒 23 的底部空间， 用于储存一定量的清水或清洁溶液。 本 发明中所指的储水区域具体是指水过滤集尘装置可用于存放水或清洁溶液容量所占据 的空间区域。 所述储水区域由技术人员在产品设计之时由数据理论推算并经实验论证 得出。 当注入液体的水位超过最大储水容量时， 高速旋风气流将会带着超出最高位置 的大量水分进入过滤海绵或电机等元器件， 造成过滤海绵的污染或堵塞， 以及电器件 的损坏。 随着含尘气体进入过滤筒的水里， 水过滤了大部分灰尘后， 含有少量灰尘的气体 再向上走时， 压水机构可以阻挡储水区域中的水和灰尘往上走， 不但保证储水区域中 水量充足， 而且由于向上气流中水分减少， 减少了对电机等电器件的损害。
一种方案中， 所述压水机构为自所述筒壁向所述水过滤筒的腔体凸设的压水环。 其中， 所述压水机构与所述筒壁之间的夹角为 α， 0° < α 90° 。 进一步地， 所述 α 的取值范围为 10° -75 ° 。 当 α值过小时， 压水环阻挡面积较小； 当 α值过大时， 水 分容易沿着压水环的下边缘进入出气口中。 优选地， α的值为 15 ° ~45 ° 。
HI为所述压水机构与所述进气口的高度距离， H为所述进气口与所述水过滤筒的 筒底的高度距离， 较佳地， H/H1的范围为等于或大于 2。 而压水机构距离进气口的距 离过小， 经过储水区域后的上升旋风气流仍过大， 压水机构不能较大的阻挡气流带走 大量的水分； 而压水机构距离进气口的距离过大， 经过储水区域后的上升旋风气流的 风速遍小， 基本不会携带水分上升。
另一种方案中， 如图 1-2所示， 所述水过滤筒 23包括上筒体 14和下筒体 22， 所 述压水机构为自所述上筒体 14向所述下筒体 22凹设的连接面 25。 所述连接面 25为 直角坡面、 倾斜坡面或弧形坡面。
再一种方案中， 所述水过滤筒 23包括上筒体 14和下筒体 22， 所述上筒体 14凹 设连接所述下筒体 22的连接面 25， 所述压水机构包含所述连接面 25和位于所述连接 面的上边缘筒壁向所述水过滤筒的腔体凸设的压水环 24。
在上述水过滤集尘装置中， 还包括位于所述水过滤筒的腔体内的网孔过滤器 15， 该网孔过滤器上设有的多个通孔为所述出气口，所述网孔过滤器 15的底端部设有挡水 部 26。
所述挡水部 26为自所述网孔过滤器 15的底端部向所述水过滤筒 23的筒壁凸设 的裙边。
所述挡水部远离网孔过滤器的端部与所述筒壁的水平距离 D， D 的范围是 l/3~3/4d, 其中 d是网孔过滤器与过滤筒壁的径向距离。
其中， 所述压水机构与所述网孔过滤器 15 的底端部处于同一水平高度， 或者所 述压水机构位于所述网孔过滤器的底端部的下方。
进一步地， 所述的水过滤集尘装置还包括旋风分离器， 该旋风分离器位于所述水 过滤筒的下游。
其中， 所述旋风分离器包括至少 2个并联的旋风体， 旋风体的数量可以为 2-9个。 本发明还提供一种水过滤吸尘器， 包括吸尘器主体， 其设有真空源和集尘装置， 所述真空源和所述集尘装置相连通， 所述集尘装置为上述的水过滤集尘装置。
下面结合附图 1-3进一步说明水过吸尘器的工作过程。
水过滤吸尘器工作前， 在水过滤筒 23 中装入一定量的清水或清洁液等， 但不能 超过储水区域的最大容量。 当水位达到储水区域的最大容量时， 利用水过滤筒 23中的 浮子 20带动磁铁 19达到最高位置，水过滤筒 23外部的磁控开关即控制真空源停止工 作， 从而避免水过滤筒 23中的水过量。
水过滤吸尘器工作时， 首先， 夹带灰尘、 颗粒等脏物的气流从进气口切向进入到 水过滤筒 23， 含尘气流先沿着水过滤筒 23的筒壁旋转向下， 进入水过滤筒 23中的储 水区域进行水过滤分离灰尘。 然后， 经水过滤的旋转气流向上， 部分旋转上升气流带 动一些水份沿筒壁旋转上升， 形成水膜。 气流、 水膜向上的过程中遇到压水机构， 如 所述筒壁向所述水过滤筒的腔体凸设的压水环、 所述上筒体 14向所述下筒体 22凹设 的连接面 25、 所述上筒体 14向所述下筒体 22凹设的连接面 25结合位于所述连接面 25的上边缘筒壁向所述水过滤筒的腔体凸设的压水环 24以及网孔过滤器 15的底端部 设有挡水部 26， 阻挡了向上气流中水分和灰尘， 不但保证储水区域中水量充足， 而且 由于向上气流中水分减少， 减少了对电机等电器件的损害， 另外， 由于向上气流中灰 尘的减少， 过滤网、 复合棉和过滤海绵等不容易堵塞， 从而提高过滤效果。 旋风进入 过滤筒往下走时会跨过压水环的阻挡再次向下旋转时， 其风力减小， 从而减少了水面 翻滚或水面气泡的产生， 使得水面会更平静， 过滤效果更好。
气流向上通过网孔过滤器 15， 进一步过滤旋转气流中的大颗粒灰尘， 并且旋转气 流向上时， 基本不会在水面产生气泡， 旋转气流到达过滤海绵 8时所含灰尘少， 极大 减少过滤海绵 8的污染， 气固分离后的脏物落入水过滤筒 23的底部。
气流旋转进入水过滤筒 23 的储水区域过滤后再旋转向上进入网孔过滤器或下游 旋风分离器的过滤方式过滤效果好， 有效实现气固分离。
为保障水过滤吸尘器的分离效率， 水过滤吸尘器在不同位置设有不同的密封圈， 比如： 尘桶底盖密封圈 17可以有效防止泄气漏灰； 设置在内尘桶 16和网孔过滤器 15 之间的内尘桶盖密封圈 13， 可以有效防止位于内尘桶 16 中的气流未经网孔过滤器上 的气孔直接排出。 另外， 网孔过滤器密封圈 12、 海绵架密封圈 9可以起到有效防止泄 气的作用。
过滤网 6、复合棉 7和过滤海绵 8可以对从出气口流出的气流进行进一步地过滤， 使得过滤效果更好。
如图 2-3所示， 水过滤筒 23包括上筒体 14和下筒体 22， 上筒体 14的截面积小， 下筒体 22的截面积大。 即水过滤筒 23的形状为上小下大， 上筒体 14和下筒体 22两 者的连接面 25为直角坡面、 倾斜坡面或弧形坡面， 坡面可以起到一定的挡水、 挡灰的 作用。 另一方面， 水过滤筒 23的截面积变大， 从进气口进入的气体旋转的角速度则会 相应变小， 旋风水过滤时水面较平静， 减少气泡的发生并减少气流携带的水分。
进一步地， 网孔过滤器 15的下端外周环设有挡水部 26， 或者在水过滤筒 23的内 壁设有凸出的压水环 24， 当含水的气体向上运行时， 挡水部 26或压水环 2可以起到 挡水的作用， 减少水对网孔过滤器 15的影响。
所述挡水部远离网孔过滤器的端部与所述筒壁的水平距离 D， D 的范围是 l/3~3/4d， 其中 d是网孔过滤器与过滤筒壁的径向距离。 当水平距离 D过大时， 水分 较易进入网孔过滤器 15， 则不能起到很好的挡水作用， 当水平距离 D过小时， 毛发、 丝线等灰尘不易从挡水部和筒壁之间的空隙掉进筒底。
本发明水过滤吸尘器包括吸尘器主体， 其设有真空源和集尘装置， 所述真空源和 所述集尘装置相连通， 所述集尘装置为上述的水过滤集尘装置。
图 4为本发明直立式水过滤吸尘器立体图， 如图 4所示， 该直立式水过滤吸尘器 100包括吸尘器主体 101和吸头 130， 该主体 101设置有真空源 （图中未示）， 真空源 用于产生抽吸力。 吸头 130与吸尘器主体 101相连通， 用于从待清洁表面吸入带有灰 尘的空气。直立式水过滤吸尘器 100包括水过滤集尘装置 102， 该水过滤集尘装置 102 安装在吸尘器主体 101上， 其与吸尘器主体 101和吸头 130的相连通， 用于实现气固 分离， 干净的气流通过真空源的出口释放到大气中。 当水过滤筒 23变脏以后， 使用者 可以将水过滤集尘装置 102从吸尘器主体 101上取出， 更换清洁的水。
图 5为本发明卧式水过滤吸尘器的立体图， 如图 5所示， 卧式水过滤吸尘器 200 包括吸尘器主体 201和吸头 230， 该吸尘器主体 201设置有真空源 （图中未示）， 真空 源用于产生抽吸力。 吸头 230与吸尘器主体 201相连通， 用于从待清洁表面吸入灰尘 和空气。所述卧式水过滤吸尘器 200包括水过滤集尘装置 202， 该水过滤集尘装置 202 安装在吸尘器主体 201上， 其与吸尘器主体 201和吸头 230的相连通， 用于实现气固 分离， 干净的气流通过真空源的出口释放到大气中。
本发明保护并不局限于说明书具体实施方式中所列举的实施例描述的具体结构 布局。 显然， 在本发明权利要求书的保护范围内， 还可以有多种不同的变型和结构组 合。
