下面参考图1-图6描述根据本发明实施例的用于除尘设备的过滤液箱100。
如图1和图2所示，根据本发明实施例的用于除尘设备的过滤液箱100，包括：箱体1、压水组件2和旋风分离器3。
箱体1上形成有进口和出口。例如，在图1的示例中，箱体1包括本体和上盖板11，本体的顶部敞开，上盖板11设在本体的顶部。其中，箱体1的本体大体形成为长方体形状，当然，本体也可以为其他形状，例如圆柱体形状等，本发明对此不作具体限定。其中，进口可以形成在本体的侧壁上，出口可以形成在箱体1的上盖板11上，但不限于此。
进一步地，参照图2，箱体1的出口处设有出口管12，出口管12的一端(例如，图2中的下端)与箱体1的内部连通，出口管12的另一端(例如，图2中的上端)位于箱体1的外部且与箱体1的外部连通。箱体1内具有过滤介质(图未示出)。其中，过滤介质可以为水等。
压水组件2设在箱体1内，压水组件2与箱体1的进口相连通，压水组件2被构造成将从进口进入的气流导向过滤介质例如水等并产生周向运动、经过滤介质过滤后的气流由出口排出。
旋风分离器3设在箱体1内且与出口相通，旋风分离器3内限定出旋风分离腔，旋风分离器3上形成有与旋风分离腔相通的旋风进口31。混有液体的气流从旋风进口31进入旋风分离腔，在离心力和重力的作用下，使得气液分离。由此，可有效地提高气液分离效果。例如，在图5的示例中，旋风进口31形成在旋风分离器3的下部，旋风进口31优选沿旋风分离器3的侧壁切向延伸。由此，可便于气流进入旋风分离腔，提高分离效率。
例如，混有污物的气流从进口进入箱体1内并经过压水组件2时，产生周向运动，由此，可降低气流的流速，增加气流与水的接触时间，从而使得污物和箱体1内的水充分混合，提高过滤效果。过滤后的气流进入旋风分离器3，在离心力和重力的作用下，使得气液进一步分离，并将分离后的气体输送至箱体1的出口。由此，提高了气液分离效果，从而有效地保护了除尘设备的位于箱体1的出口的下游的电机，保证了除尘设备的正常运行，且延长了除尘设备的使用寿命，降低了使用成本。
根据本发明实施例的用于除尘设备的过滤液箱100，通过在过滤液箱100内设置压水组件2和旋风分离器3，由此，可使得从箱体1的进口进入的气流产生周向运动，降低气流的流速，使得从进口进入的气流可以与箱体1中的过滤介质充分混合，提高过滤效率，并通过旋风分离器3对流向出口的气液混合物进行分离，进一步地提高了气液分离效果。
根据本发明的一些实施例，压水组件2包括进口管21和压水板22。参照图2并结合图3，进口管21具有第一端和第二端。其中，进口管21的第一端与箱体1的进口相连通。例如，在图2的示例中，进口处可以设置连接管13，进口管21的第一端与连接管13相连以与进口连通。可选地，进口管21的第一端与箱体1可拆卸地连接。由此，方便了压水组件2的安装和拆卸。
具体而言，进口管21包括第一管段和第二管段。进口管21的第一端朝向远离进口的方向延伸形成第一管段，第一管段的自由端朝向本体的底部延伸形成第二管段。其中，第一管段与第二管段之间优选圆滑连接，由此，可减小气流在进口管21中的流动阻力。
可选地，进口管21的第一管段上且靠近进口管21的第一端处设有环绕在进口管21的外周壁上限位环211。由此，可限制压水组件2在朝向箱体1外部的方向上运动，从而使得压水组件2的位置稳定。
压水板22上形成有贯通的压水口221，例如，在图2的示例中，压水板22相对于所述箱体1的底壁水平设置，压水口221形成在压水板22的中央，进口管21的第二端与压水板22的上表面相连且与压水口221相通。由此，可有效地压制压水口221处的水花，降低气流的流速，增加气流与水的接触时间，使得污物与水充分混合。可选地，压水板22与进口管21的第二端一体成型，工艺简单，便于加工。
进一步地，压水组件2还包括与压水板22的下表面连接的至少一个叶片23。其中，压水板22的下表面上的叶片23可以为一个，也可以为多个。例如，在图2和图3的示例中，叶片23为多个且多个叶片23沿压水口221的周向彼此间隔开设置。由此，当气流从压水口221流出时，在叶片23的作用下，气流可以周向运动，从而降低了气流的流速，使得污物与水充分混合，提高了过滤效率。
可选地，多个叶片23沿压水口221的周向均匀间隔分布。由此，可使得气流的流速均匀，从而可以进一步地提高污物与水的混合效果。
根据本发明的一些实施例，相邻两个叶片23之间的距离相对于压水口221的中心从内到外逐渐增大，在压水板22的圆周方向上形成多条渐扩流道。由此，可进一步地降低气流的流速。例如，在图3的示例中，叶片23形成为平滑的曲面，叶片23相对于压水口221的中心从内向外延伸，结构简单，便于加工，但不限于此。
具体地，叶片23相对于压水板22非平行设置。例如，在图2的示例中，叶片23相对于压水板22垂直设置。
可以理解地，叶片23的数量、形状等可以根据过滤液箱100的实际规格尺寸作适应性调整，本发明对此不作具体限定。
根据本发明的另一些实施例，参照图6，压水板22的下表面上形成有多个自压水口向四周放射的、曲线延伸的沟渠状压水槽24，使压水板22整体形成类似喇叭花状结构。也就是说，压水板22的下表面上的压水槽24可以为一个，也可以为多个。例如，在图6的示例中，压水槽24为多个，且多个压水槽24沿压水口221的周向彼此间隔开设置。由此，当气流从压水口221流出时，在压水槽24的作用下，气流可以周向运动，从而降低气流的流速，使得污物与水充分混合，提高了过滤效率。
具体地，多个压水槽24沿压水口221的周向均匀间隔分布。由此，可使得气流的流速均匀，从而可以进一步地提高污物与水的混合效果。
根据本发明的一些实施例，每个压水槽24的宽度相对于压水口221的中心从内到外逐渐增大。由此，可在压水板221的圆周方向上形成多条渐扩流道，使得气流周向运动，降低气流的流速。
进一步地，例如，在图6的示例中，每个压水槽24的延伸方向从内到外偏离压水口221的径向方向，压水板22整体大致形成喇叭花状。其中，压水槽24可以沿顺时针方向偏离压水口221的径向方向，也可以沿逆时针方向偏离压水口221的径向方向。由此，可以更进一步地提高污物与水的混合效果。
可以理解的是，压水槽24的数量、形状等可以根据过滤液箱100的实际规格尺寸作适应性调整，本发明对此不作具体限定。
此外，还可以在压水板22上设置其他可以在压水板22的圆周方向上形成渐扩流道的结构，只要能实现使得压水口221处的气流产生周向运动即可。
具体地，旋风分离器3被构造成由旋风进口31进入到旋风分离腔内的气流的旋转方向与流经压水组件2的气流的旋转方向相同。例如，在图2的示例中，从压水板22的叶片中流出来的气流顺时针转动，则进入到旋风分离器3内的气流也是顺时针方向转动；同样地，从压水板22的叶片中流出来的气流逆时针转动，则进入到旋风分离器3内的气流也是逆时针方向转动。由此，可使得箱体1内的整体流动更加流畅，从而有效地减小了气流的流动阻力。
这里，需要说明的是，流经压水组件2的气流为进入过滤液箱100的混有污物的初始气 流，进入到旋风分离腔内的气流为上述初始气流与过滤液箱中的过滤介质混合后，污物被分离后的混有少量液滴的干净气流。
根据本发明的一些实施例，旋风分离腔的至少一部分被构造成在从上到下的方向上横截面积逐渐减小的结构。具体而言，可以将旋风分离腔的上部构造成从上到下的方向上横截面积逐渐减小的结构，也可以将旋风分离腔的下部构造成从上到下的方向上横截面积逐渐减小的结构，还可以将旋风分离腔整体构造成从上到下的方向上横截面积逐渐减小的结构。例如，参照图5，旋风分离腔的下部从上到下的方向上横截面积逐渐减小。
进一步地，旋风分离器3的底部形成有贯通的连通口32，旋风分离器3内设有浮子4以常闭状态封闭连通口32。可选地，连通口32的尺寸小于浮子4的尺寸。例如，参照图2并结合图5，浮子4的形状为球形，连通口32的形状为圆形，连通口32的直径小于浮子4的直径。由此，可将浮子4卡在连通口32处，防止浮子4从旋风分离器3中滑出，从而可以利用浮子4阻挡箱体1底部溅起的水花。
可以理解的是，也可以在连通口32处设置限位筋54例如十字形的限位筋54等结构，以防止浮子4从旋风分离器3中滑出，本发明对此不作特殊限定。
具体而言，出口管12的一端(例如，图2中的下端)伸入旋风分离腔内，当浮子4打开连通口32时浮子4适于封堵出口管12的上述一端，即出口管12的下端。由此，当箱体1内吸入一定量的污物时，箱体1内的水位升高，在浮力的作用下，浮子4浮起封堵出口管12的下端，使得除尘设备停机报警，保证除尘设备的安全运行。此外，当旋风分离器3内的积水达到一定量时，浮子4在吸力及浮力作用下浮起可使得积水流出旋风分离器3，旋风分离器3内一部分水流出后，浮子4所受浮力与重力再次平衡时，浮子4再次阻塞连通口32，保证旋风分离器3的分离效果。
根据本发明的一些实施例，参照图2并结合图5，旋风分离腔的顶部敞开，箱体1进一步包括：出口盖板14，出口盖板14设在上盖板11上且封闭旋风分离腔的顶部，其中箱体1的出口形成在出口盖板14上。
具体地，出口盖板14与上盖板11可拆卸地连接。由此，可便于出口盖板14的拆卸与装配，从而便于清洗箱体1。例如，出口盖板14与上盖板11可通过卡扣或者螺纹连接，但不限于此。当需要清洗箱体1时，只需将出口盖板14从上盖板11上拆卸下来，就可对箱体1进行清洗，结构简单，清洗方便。
下面参考图1-图6描述根据本发明的两个具体实施例。
实施例一：
参照图1-图5，用于除尘设备的过滤液箱100，包括箱体1、压水组件2和旋风分离器3。
其中，箱体1包括本体、上盖板11和出口盖板14，本体的顶部敞开，上盖板11设在本体的顶部，出口盖板14与上盖板11可拆卸地连接。由此，可便于出口盖板14的拆卸与装配，从而便于清洗箱体1。
箱体1的本体大体形成为长方体形状。箱体1上形成有进口和出口，进口形成在本体的侧壁上，出口形成在箱体1的出口盖板14上。
箱体1的出口处设有出口管12，出口管12的一端(例如，图2中的下端)与箱体1的内部连通，出口管12的另一端(例如，图2中的上端)位于箱体1的外部且与箱体1的外部连通。
压水组件2包括进口管21、压水板22和设在压水板22的下表面上的多个叶片23。具体地，进口管21具有第一端和第二端，进口处设置连接管13，进口管21的第一端与连接管13相连以与进口连通。进口管21的第一端与箱体1可拆卸地连接。由此，可便于压水组件2的维修，提高压水组件2的可维修性。
更加具体地，进口管21还包括第一管段和第二管段。进口管21的第一端朝向远离进口的方向延伸形成第一管段，进口管21的第一管段上且靠近进口管21的第一端处设有环绕在进口管21的外周壁上限位环211，限位环211的直径大于进口管21的直径。由此，可限制压水组件2在朝向箱体1外部的方向上运动，从而使得压水组件2的位置稳定。第一管段的自由端朝向本体的底部延伸形成第二管段。第一管段与第二管段之间圆滑连接，由此，可减小气流在进口管21中的流动阻力。
压水板22与进口管21的第二端一体成型，其中，压水板22水平设置，压水板22的上表面与进水管的第二端相连，且压水板22的中央形成有与进口管21的第二端相通的压水口221。由此，可有效地压制出水口处的水花，降低气流的流速，增加气流与水的接触时间，使得污物与水充分混合。
多个叶片23沿压水口221的周向彼此均匀间隔开设置，且相邻两个叶片23之间的距离相对于压水口221的中心从内到外逐渐增大，具体而言，每个叶片23相对于压水口221的中心从内到外曲线延伸，在压水板22的圆周方向上形成多条渐扩流道。由此，当气流从压水口221流出时，在叶片23的作用下，气流可以周向运动，从而降低了气流的流速，增加了污物与水的接触时间，使得污物与水充分、均匀地混合，提高了过滤效率。
旋风分离器3设在箱体1的上盖板11上且与出口相通。具体地，旋风分离器3内限定出旋风分离腔，旋风分离腔的顶部敞开，箱体1的出口盖板14设在上盖板11上且封闭旋风分离腔的顶部。
旋风分离器3的上部形成有沿旋风分离器3的切向延伸并与旋风分离腔相通的旋风进口31。混有液体的气流从旋风进口31进入旋风分离腔，在重力和离心力的作用下，使得气液分离。由此，可有效地提高气液分离效果。
旋风分离器3被构造成由旋风进口31进入到旋风分离腔内的气流的旋转方向与流经压水组件2的气流的旋转方向相同。
旋风分离腔的下部在从上到下的方向上横截面积逐渐减小。旋风分离器3的底部形成有贯通的圆形连通口32，旋风分离器3内设有球形的浮子4以打开和关闭连通口32。出口管12的下端伸入旋风分离腔内，当浮子4打开连通口32时浮子4适于封堵出口管12下端。其中，连通口32的尺寸小于浮子4的尺寸。由此，可将浮子4卡在连通口32处，防止浮 子4从旋风分离器3中滑出，从而可以利用浮子4阻挡箱体1底部溅起的水花。且当箱体1内吸入一定量的污物时，箱体1内的水位升高，在浮力的作用下，浮子4浮起封堵出口管12的下端，使得吸尘器停机报警，保证吸尘器的安全运行。此外，当旋风分离器3内的积水达到一定量时，浮子4在吸力及浮力作用下浮起以使得积水流出旋风分离器3，旋风分离器3内一部分水流出后，浮子4所受浮力与重力再次平衡时，浮子4再次阻塞连通口32，保证旋风分离器3的分离效果。
例如，当混有污物的气流从箱体1的进口进入箱体1内后，经过压水组件2，并从压水组件2流出时，产生周向运动，流速降低，从而增加了气流中的污物与箱体1内的水的接触时间，使得污物与水充分混合，实现初步分离。然后，初步分离后混有液体的气流从旋风分离器3的旋风进口31进入旋风分离腔，在离心力和重力的作用下，使得气液进一步分离，并将分离后的气体输送至出口，并通过出口排出。
实施例二：
如图6所示，本实施例与实施例一的结构大致相同，其中相同的部件采用相同的附图标记，不同之处在于：实施例一中的压水组件2的压水板22的下面上形成有多个间隔分布的叶片23，而本实施例中，压水板22的下表面上形成有多个间隔分布的压水槽24。实施例一中的分离器为旋风分离器3，而本实施例中的分离器为气液分离器5。
参照图6，多个压水槽24沿压水口221的周向彼此均匀间隔开设置，且每个压水槽24的宽度相对于压水口221的中心从内到外逐渐增大，具体而言，每个压水槽24从内到外沿顺时针方向偏离压水口221的径向方向，以在压水板22的圆周方向上形成多个渐扩流道。由此，当气流从压水口221流出时，在压水槽24的作用下，气流可以周向运动，并逐渐降低气流的流速，使得污物与水充分、均匀地混合，提高了过滤效率。
根据本发明实施例的用于除尘设备的过滤液箱100，通过在过滤液箱100内设置可以使进入箱体1内部的气流产生周向运动的压水组件2，使得混有污物的气流与箱体1中的水混合。由此，可降低气流的流速，增加气流与水的接触时间，使得污物与水充分混合，从而提高污物与水的混合效果，提高过滤效率。此外，在箱体1的出口处设置旋风分离器3，可进一步地提高气液分离效果，从而保证除尘设备的安全运行。
根据本发明第二方面实施例的除尘设备(图未示出)，包括根据本发明上述第一方面实施例的过滤液箱100。
根据本发明实施例的除尘设备，通过设置上述第一方面实施例的过滤液箱100，提高了除尘设备的整体性能。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
