本发明涉及气固液分离技术领域，具体涉及一种气固液分离装置及具有其的吸尘器。
背景技术
随着人们生活质量水平的提高，科技的不断发展，对机械设备的依赖性就越强。小型轻便吸尘器已经逐渐步入社会家庭，成为日常清洁工作中不可或缺的得力助手。但是目前家用吸尘器多数是干吸型，吸尘后仍需人工拖抹清洁区域，无法满足用户的进一步需求；而现有湿吸尘器中污水分离器分离污水和尘污方式大多采用阻隔撞击、单层过滤方式，污水不规则飞溅，容易堵塞过滤孔，分离效果差。
为了解决上述技术问题，中国专利文献CN103767628A公开了一种具分离装置的干湿两用吸尘器，包括：用于一级旋风且上端开口的尘筒、设置在尘筒内的旋风罩、以及用于封闭尘筒上端开口且固定旋风罩上端的电机基座，其中电机基座至少部分***到旋风罩内。污水和灰尘通过尘筒上的进风口进入旋风罩中，灰尘在旋风罩的作用下被过滤掉大部分，再经过 设置在旋风罩中的过滤装置除去；而污水则在旋风和重力作用下顺利进入尘筒底部收集，但是对于进入尘筒中的气体，该吸尘器并不能进行有效的分离和清洁。
发明内容
因此，本发明要解决的技术问题在于克服现有技术中的分离装置不能将气体和固液有效分离的缺陷，从而提供一种气体和固液能够有效分离，并排出洁净气体的气固液分离装置及具有其的吸尘器。
为了解决上述技术问题，本发明提供了一种气固液分离装置，包括：

具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
此外，下面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
如图1-3所示的气固液分离装置的一种具体实施方式，包括筒体1和安装在筒体1内部的旋风罩2。筒体1包括外壁和内壁及形成于所述外壁和内壁之间的环形内腔，所述外壁上设有气固液混合物进口11，所述环形内腔的上部为允许过滤后的气体排出的开口12。旋风罩2设置在所述环形内腔中，所述旋风罩2的侧壁与进口11相对应的位置设有一气固液混合物的入口21，气固液混合物通过外接管道依次经筒体1的进口11和旋风罩2的入口21进入筒体1的环形内腔中。所述旋风罩2与所述筒体1的所述外壁之间形成用于固液过滤的第一通道3，所述第一通道3延伸至所述筒体1的底部，所述第一通道3上部设有用于固液过滤的第三过滤层31。所述旋风罩2与所述筒体1的所述内壁之间形成用于气体过滤的第二通道4，所述第二通道4的上部与所述环形内腔的开口12贯通，且所述旋风罩2上设有允许 气体从所述第一通道3进入所述第二通道4过滤的第一过滤层22，在本实施例中，第一过滤层22为成型在旋风罩2侧壁上、且靠近气固液混合物的入口21的过滤孔，第三过滤层31为过滤网，且过滤网的孔径小于过滤孔的孔径，以将大部分污物首先拦截。
为了最大程度上保证筒体的密封性能，在所述开口12处还设有密封件5，在本实施例中，密封件5为与环形内腔顶部适配的密封圈。为了进一步提高气体的过滤效果，所述开口12处设有用于气体过滤的第二过滤层13，所述第二过滤层13填充在所述密封件5的预留空间中。具体地，所述第二过滤层13为过滤棉。
为了有效隔离分离后的气体和固液，在所述旋风罩2的下端滑动设置有阀体6，以将所述第一通道3和所述第二通道4隔开，所述阀体6、所述旋风罩2和所述筒体1的内壁共同围合成所述第二通道4。具体地，所述旋风罩2的下端成型有四个卡勾23，所述阀体6的上端相应位置成型有四个与所述卡勾23适配的凸台61，凸台61搭接在卡勾23的上方，所述阀体6和所述旋风罩2通过所述卡勾23和所述凸台61的配合实现滑动连接，即在筒体1的底部的固液量增加时，阀体6上浮，防止固液过满溢出筒体1。为了进一步防止分离后的气体经阀体6与旋风罩2的侧壁之间的间隙进入筒体1底部，在阀体6的顶面还贴合有棉垫62。
所述旋风罩2包括罩体24和成型在所述罩体24外壁上的螺旋筋25，螺旋筋25在罩体24加工时与其一体成型，螺旋筋25自罩体24顶端向底端延伸，所述螺旋筋25将所述第一通道3分隔成若干螺旋风道，所述气固液混合物在所述螺旋风道的离心作用下，气体经所述第一过滤层22进入所述第二通道4后排出，固液在自身重力作用下经所述第三过滤层31过滤后暂存在所述筒体1底部。
具体地，所述罩体24包括成型在上的倒凸台241和成型在下的柱体 242，倒凸台241的最大直径等于筒体1的环形内腔的最大内径，以使得罩体24可以牢固安装在筒体1中，柱体242与筒体1的外壁和内壁之间均预留有空间，以形成第一通道3和第二通道4；所述倒凸台241中成型有连通所述第二通道4和所述开口12的吸风口2411。为了进一步提高气体和固液的分离效果，在所述开口12处还设有电机，所述气固液中的气体在旋风罩2和所述电机的作用下依次经第二通道4、吸风口2411和开口12排出。当筒体1底部的固液量达到一定程度时，阀体6上浮至关闭吸风口2411的位置，以防止液体进入电机内部，对其造成损坏。
所述筒体1的底部成型有用于固液排出的出口和安装在所述出口上的盖体，盖体包括一与出口适配的堵块14和安装在堵块14上的堵块盖15。当筒体1底部的固液量达到上限时，打开出口上的堵块14和堵块盖15，将其及时排出。
在使用该气固液分离装置时，气固液混合物在旋风罩2和电机的共同作用下，依次经筒体1的开口12和旋风罩2的入口21进入筒体1的环向内腔中，并在自身重力作用下，固体和液体直接经第一通道3中的过滤网过滤后进入与第一通道3连通的筒体1底部暂存；而分离后的气体则依次经过旋风罩2侧壁上的过滤孔、第二通道4、吸风口2411和过滤棉后，经环形内腔的开口12排出，由此实现了气体和固液的分离，并能提供净化后的气体和液体，实现循环利用。
作为替代的实施方式，在旋风罩2的底部还可以成型朝向筒体1的内壁延伸的环形板，环形板将第一通道3和第二通道4有效隔离。
作为替代的实施方式，第二通道4的顶部一直向上延伸至环形内腔的开口12处，并在开口12处填充有用于气体过滤的过滤棉。
作为替代的实施方式，旋风罩2的下端和阀体6的上端可以分别成型 滑轨和滑块，以实现滑动连接。
本发明还提供了一种吸尘器，包括所述的气固液分离装置。该吸尘器可以为手持式等小型吸尘器，轻便小巧，使用方便。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
