Description

一种过滤装置及具有该过滤装置的除尘设备
本申请要求于2015年11月30日提交中国专利局、申请号为201510861517.4、发明名称为“过滤装置及具有该过滤装置的除尘设备”，申请号为201510861518.9、发明名称为“一种过滤装置及除尘设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及除尘技术领域，特别是涉及一种过滤装置。此外，本发明还涉及一种具有该过滤装置的除尘设备。
背景技术
随着经济建设的快速发展，对环境的要求也越来越高，各种各样的过滤装置应运而生，吸尘器一般利用电动机高速旋转，在密封的壳体内产生空气负压，吸取尘屑。
请参考图1，图1为一种典型的过滤装置的结构示意图，其中，图中箭头所示的方向为过滤装置工作时尘屑的运动方向。
从图1中箭头所示的方向可以看出，在现有技术的过滤装置中，动力电机与过滤器11连通，将集尘室12中的空气抽出，在集尘室12中形成负压，使空气和尘屑在动力电机的作用下，依次经过吸尘管13和风道，进入集尘室12，绕过滤器11旋转并按螺旋的趋势逐渐在集尘室12内汇聚，达到吸尘的目的。
但是，随着尘屑的增多，收集到集尘室12里的尘屑容易受动力电机的影响，产生向过滤器11移动的趋势，使尘屑粘附在过滤器11上，阻塞过滤器11的滤网。这样不仅会增加动力电机的电耗，增大除尘设备的噪音，降低除尘效率；而且会影响过滤器11的使用寿命，增加过滤器11的维护频次，并增加清洁成本。
请参考图2，图2为另一种典型的过滤装置的结构示意图，其中，实线箭头所指方向为动力部件形成的动力方向，虚线箭头所指方向为尘屑的运动方向。
图2为在图1基础上改进的一种过滤装置的结构示意图，将进入集尘 室12的风道改为螺旋风道，使尘屑进入集尘室12后，在过滤器11的外周形成如图2所示的螺旋风，从而使尘屑尽可能远送至集尘室12的端部，远离过滤器11，以延长过滤器的使用寿命，降低过滤装置的噪音和电耗，降低吸尘的成本。
图2中的过滤装置在一定程度了延长了过滤器11的使用寿命，并提高了除尘效率。但是，在一些尘屑较多的场合，图2所示的过滤装置也很难满足吸尘要求。
因此，如何提高过滤装置的除尘效率，是本领域技术人员目前需要解决的技术问题。

具体实施方式
本发明的核心是是提供一种过滤装置，该过滤装置具有较高的除尘效率和工作效率。本发明的另一个核心是提供一种具有上述过滤装置的除尘设备。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
请参考图3和图4，图3为本发明所提供的过滤装置一种具体实施方式的结构示意图，图4为图3所提供的过滤装置的气流轨迹示意图。
在一种具体的实施方式中，本发明要提供了一种过滤装置，包括进风口、第一进风通道、第一集尘室11及设于第一集尘室11内部的第一过滤器12，第一进风通道连通进风口和第一集尘室11，还包括设于第一过滤器12后侧的第二集尘室21及设于第二集尘室21内部的第二过滤器22、连通第一过滤器12和第二集尘室21的第二进风通道，第二过滤器22与出风口连通；第二过滤器22安装在第二集尘室21内靠近第一过滤器12的端面。
该过滤装置工作时，在动力部件的作用下，在第一集尘室11和第二集尘室21内产生负压，带着尘屑的气体经进风口先进入第一集尘室11，气体经第一过滤器12过滤后进入第二集尘室21，经第二过滤器22过滤后，进入第二过滤器22的内部，经出风口并经动力部件流出。
过滤装置工作过程中，气流依次经过进风口、第一进风通道、第一集 尘室11、第一过滤器12、第二进风通道、第二集尘室21、第二过滤器22、出风口，具体的气流轨迹可参考附图4。
第二集尘室21位于第一过滤器12的后侧，第二过滤器22安装在第二集尘室21内靠近第一过滤器12的端面，也就是说，在该过滤装置中，第一过滤器12与第二过滤器22背靠背设置，具体结构请参考附图3，此种设置方式对第二级过滤器22没有空间限制，两级过滤器可以采用功率相同或相近的过滤器，二者背靠背安装，结构紧凑，既节省空间，又能获得两级过滤的效果，提高除尘效率。
与现有技术相比，该过滤装置具有两个过滤器，能够进行两级过滤，且结构紧凑。在动力部件的作用下，气流首先进入第一集尘室11内，在第一集尘室11内流动的过程中，甩掉颗粒较大的尘屑，然后气流进入第一过滤器12；通过第二进风通道进入第二集尘室21，在第二集尘室21内流动的过程中再甩掉一部分尘屑，然后气流进入第二过滤器22，经出风口流出。
该过滤装置能够进行两级过滤，可以进一步提高尘屑的清除效率，提高气流的干净程度，提高工作效率和除尘效率，并且能够延长动力部件的使用寿命。
进一步的，第一进风通道和第二进风通道中至少一者为螺旋进风通道。
进入两个集尘室的风道中至少一个为螺旋进风通道，螺旋进风通道能够使气流进入集尘室后，在过滤器的外周形成螺旋风，按照螺旋的方式运动，从而使尘屑尽可能远送至集尘室的端部，远离过滤器，以延长过滤器的使用寿命。
同时螺旋风中的尘屑具有一定的离心力，具有远离过滤器的运动趋势，气流流动过程中，容易将尘屑甩出，使气体和尘屑分离，将尘屑留在集尘室内。
优选的，第一进风通道和第二进风通道，二者均为螺旋进风通道，能够提高各级过滤过程中的过滤效率，提高两个过滤器的使用寿命。
具体的，第一过滤器12的底部由第一螺旋板13环绕第一筒体14形成螺旋进风通道，第二过滤器22的底部由第二螺旋板23环绕第二筒体24形成螺旋进风通道；第一筒体14和第二筒体24的端部相抵靠，两个螺旋 进风通道的旋向相反。
第一螺旋板13环绕第一筒体14至少为1周的90％，第二螺旋板23环绕第二筒体24也至少为1周的90％，即可形成螺旋进风通道，使经过的气流按照螺旋的方式流动。螺旋板环绕筒体的长度越长，形成的螺旋风的趋势越强，但是，会使得螺旋进风通道占的体积较大。优选的，第一螺旋板13环绕第一筒体14为1周或大于1周小于1.5周，第二螺旋板23环绕第二筒体24为1周或大于1周小于1.5周。
第一过滤器12的底部安装在第一筒体14上，在第一筒体14的外侧由第一螺旋板13形成第一集尘室11的第一进风通道；第二过滤器22的底部安装在第二筒体24上，在第二筒体24的外侧由第二螺旋板23形成第二集尘室21的第二进风通道。第一筒体14和第二筒体24的直径可以相同，相应的两个过滤器的尺寸也可以相同。
第一筒体14和第二筒体24的端部相抵靠，两个螺旋进风通道的旋向相反；通过第一筒体14和第二筒体24不但实现了第一过滤器12和第二过滤器22的底部背靠背安装，并且在两个过滤器之间预留了一定的空间，可以在此空间设置两个集尘室的进出通道，旋向相反的两个螺旋进风通道，便于实现对此空间的划分，使整体结构紧凑，既节省了空间，又能实现两级过滤。
请参考图5至图8，图5为图3所提供的过滤装置的局部结构的第一视角的示意图，图6为图3所提供的过滤装置的局部结构的第二视角的示意图，图7为图3所提供的过滤装置的局部结构的第三视角的示意图，图8为图3所提供的过滤装置的局部结构的第四视角的示意图。
进一步优选的实施方式中，第一筒体14和第二筒体24之间的端面设有挡板，两个筒体的侧面设有第一隔板31和第二隔板32；第一隔板31和第二隔板32的两端分别连接第一螺旋板13和第二螺旋板23；
第一隔板31、第二隔板32、第一螺旋板13、第二螺旋板23，四者在两个筒体周部形成三个空间，第一空间连通进风口和第一集尘室11，第二空间连通第一过滤器12和第二集尘室21，第三空间连通第二过滤器22和出风口。
两个螺旋板和两个隔板，将两个筒体外部的空间划分为三个空间，第一空间连通进风口和第一集尘室11，相当于第一进风通道，气***于第一隔板31的一侧时，沿着第一螺旋板13流动时能够进入第一集尘室11，此为第一空间；第二空间连通第一过滤器12和第二集尘室21，相当于第二进风通道，气***于第一隔板31的另一侧与第二隔板32之间时，沿第二螺旋板23流动能够进入第二集尘室21，此为第二空间；第三空间连通第二过滤器22和出风口，第二隔板32的另一侧与两个螺旋板形成第三空间。
进一步具体的实施方式中，第一螺旋板13和第二螺旋板23的起始端相连，第一隔板31的一端与起始端连接，另一端与第一螺旋板13连接；
第一隔板31、第一筒体14的外侧面和第一螺旋板13的前侧面形成第一空间，具体结构如图5所示；
位于第一隔板31和第二隔板32之间的第一筒体14的侧面设有第一开口15；第一隔板31、第二隔板32、第二筒体24的外侧面和第二螺旋板23的前侧面形成第二空间，具体结构如图6所示；
位于第二隔板32的另一侧的第二筒体24的侧面设有第二开口25；第二隔板32、第一螺旋板13的后侧面和第二螺旋板23的后侧面形成第三空间，具体结构如图7和图8所示。
需要说明的是，第一过滤器12和第二过滤器22二者的底部背靠背设置，第一螺旋板13的前侧是指在第一集尘室11内，远离第一过滤器12底部的方向；第二螺旋板23的前侧是指在第二集尘室21内，远离第二过滤器22底部的方向。
第一螺旋板13和第二螺旋板23旋向相反，两个螺旋板的起始端相连，两个螺旋板从同一位置开始，分别沿着两个筒体，向两端延伸，形成了两个集尘室的两个进风通道。
第一隔板31安装在两个螺旋板起始端的位置，如图5所示，第一隔板31的一侧为第一螺旋板13形成的通道，即为第一空间，使进风口位于此通道内，由于第一隔板31的阻挡，从进风口进入的气体均沿第一螺旋板13进入第一集尘室11。
第一开口15位于第一隔板31和第二隔板32之间的第一筒体14的侧 面；气体进入第一集尘室11后，甩掉部分尘屑后，进入第一过滤器12，然后经过第一筒体14的内部和第一开口15能够进入第二空间，如图6所示，由于第一隔板31和第二隔板32的阻挡，气体沿第二螺旋板23进入第二集尘室21。
如图7和图8所示，第二隔板32的另一侧和两个螺旋板形成第三空间，使出风口位于此空间内；在第三空间内，第二筒体24的侧面设第二开口25，则进入第二集尘室21的气体可以经第二过滤器22、第二筒体24的内部和第二开口25进入第三空间，然后经出风口流出。
进一步的，第二开口25所在的第二筒体24的侧面的圆心角，大于，第一开口15所在的第一筒体14的侧面的圆心角。
第二开口25所在的区域连通第二过滤器22和出风口，第一开口15所在的区域连通第一过滤器12和第二进风通道，动力部件通过出风口使第一集尘室11和第二集尘室21内产生负压，第二开口25所在的区域的圆心角大，便于将第二开口25设置的大一些，动力部件工作时，第二开口25较大，能够加快第一集尘室11和第二集尘室21产生负压的速度。
上述各具体的实施方式中，第一过滤器12为圆孔状过滤器，第二过滤器22为圆孔状过滤器或长条状过滤器。
第二过滤器22可以为圆孔状过滤器，也可以为长条状过滤器，经过第一过滤器12的过滤，尘屑中的大部分杂质已经留在第一集尘室11，气流在第二集尘室21内运动后，进入第二过滤器22的气流中基本不携带尘屑，圆孔状过滤器或长条状过滤器均能够满足过滤要求，不过，长条状滤网相对于圆孔状滤网加工工艺更简单，成本更低，适用于更多材质，可以进一步降低过滤装置的加工难度和成本。
进一步具体的实施方式中，第一过滤器11和第二过滤器21位于同一个圆柱形壳体4内，圆柱形壳体4的两端分别为第一集尘室11和第二集尘室21。
第一集尘室11和第二集尘室21的横截面可以相同，也可以不同。优选的，使两个集尘室的横截面相同，两个集尘室为背靠背设置，这样两个集尘室可以共用同一个壳体，圆柱形壳体4的两端分别为两个集尘室，可 以通过一个模具加工制作圆柱形壳体4，节省成本，既便于制造，又便于安装。
具体的，进风口和出风口均设置在圆柱形壳体4的侧面。
圆柱形壳体4的两端分别为第一集尘室11和第二集尘室21，在圆柱形壳体4内，两个过滤器的底部背对背安装，并且通过两个筒体预留了一定的空间，便于设置进风口和出风口，安装两个过滤器的两个筒***于圆柱形壳体4的中部，进风口和出风口均设置在圆柱形壳体4的中部的侧面。
本发明的核心是提供一种过滤装置，该过滤装置的吸尘速度较快，工作效率较高。本发明的另一个核心是提供一种具有上述过滤装置的除尘设备。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
请参考图9至图12，图9为本发明所提供的过滤装置一种具体实施方式的机构示意图，图10为图9所示的过滤装置的局部结构的示意图，图11为图9所示的过滤装置的另一局部结构的示意图，图12为图9所示的过滤装置的又一局部结构的示意图。
本发明提供了一种过滤装置，包括吸尘管1、第一进风通道、第一集尘室11及位于第一集尘室11内部的第一过滤器12，第一过滤器12的顶端设有第一筒体14，第一过滤器12和第一筒体14的内部形成第二集尘室21，设有第二过滤器22，第二过滤器22与出风口连通；第二过滤器22通过第二筒体24安装在第二集尘室21内部，使得第一过滤器12与第二过滤器22在轴线方向上错开。
过滤装置工作时，在动力部件的作用下，在第一集尘室11和第二集尘室21内产生负压，带着尘屑的气体经吸尘管、第一进风通道进入第一集尘室11中，气体经第一过滤器12过滤后进入第二集尘室21，在第二集尘室21内通过第二过滤器22过滤后，经出风口流出。
与现有技术相比，该过滤装置具有两个过滤器，能够进行两级过滤。在动力部件的作用下，气流首先进入第一集尘室11内，在第一集尘室11内流动的过程中，甩掉颗粒较大的尘屑，然后气流进入第一过滤器12；由 于第一过滤器12与第二过滤器22在轴线方向上错开，进入第一过滤器12的气流向第二过滤器22所在的位置流动，此过程中，能够再甩掉一些尘屑，然后气流进入第二过滤器22，经出风口流出。
该过滤装置的第二过滤器22设置在第一过滤器12及其延伸的第一筒体14的内部，合理利用了空间，该过滤装置能够利用较小的空间进行两级或多级过滤；该过滤器的结构简单，直接利用第一过滤器12及其延伸的第一筒体14的内部作为第二集尘室21，具体结构如图10所示，既节省空间，又便于安装，便于加工制造。
该过滤装置能够进行两级过滤，可以进一步提高尘屑的清除效率，提高气流的干净程度，提高工作效率和除尘效率，并且能够延长动力部件的使用寿命。
在一种具体的实施方式中，第一筒体14抵顶第一集尘室11的端部，在轴线方向上，第二筒体24与第一过滤器12重合，第二过滤器22与第一筒体14重合。
第一筒体14的端部为封闭的，可以抵顶第一集尘室11的端部，也可以不抵顶第一集尘室11的端部。第一筒体14抵顶第一集尘室11的端部时，第一筒体14内的空间较大，能够使得第二集尘室21的体积较大。
在轴线方向上，安装第二过滤器22的第二筒体24与第一过滤器12重合，第二过滤器22与第一筒体14重合，能够使得第一过滤器12和第二过滤器22在轴线方向上完全错开，如图9所示，进入第一过滤器12内部的气体，不会直接进入第二过滤器22，会在第二集尘室21内，向第二过滤器22移动，能够在移动过程中，将部分尘屑甩出气流，降低第二过滤器22的工作压力。
进一步具体的实施方式中，第一过滤器12的底端与第二筒体24的底端之间设有挡板。
此挡板、第二筒体24和第二过滤器22的外壁、第一过滤器12和第一筒体14的内壁、第一筒体14的端部，四者共同形成了第二集尘室21。气流进入第一过滤器12后，一方面由于挡板的阻挡，另一方面由于动力部件的负压作用，使气流向第二过滤器22移动，经过过滤后，进入第二过滤器 22。
上述各具体的实施方式中，第一进风通道为螺旋进风通道，如图3所示。
气流通过第一进风通道进入第一集尘室11，在螺旋进风通道的作用下，进入第一集尘室11后，按照螺旋的方式在第一集尘室11内运动，将尘屑远送至第一集尘室11的端部，远离第一过滤器12。
气流螺旋运动的过程中，其内部的尘屑具有一定的离心力，尘屑在离心力的作用下靠近第一集尘室11的侧壁，并沿着侧壁运动，在此过程中，尘屑远离第一过滤器12，并且在气流向端部推送尘屑的过程中，很容易将尘屑甩出气流，留在第一集尘室11中，提高了第一级过滤过程中的除尘效率，并且还延长第一过滤器12的使用寿命。
进一步具体的实施方式中，第一过滤器12前侧，第一筒体14的外侧设有第一螺旋板，第一螺旋板的螺旋方向与第一进风通道的螺旋方向相同。
第一螺旋板环绕第一筒体14至少为1周的90％，第一螺旋板将第一集尘室11分成了旋风工作腔和粉尘收集腔，靠近第一进风通道的一端为旋风工作腔，另一端为粉尘收集腔。螺旋气流运动时能够携带尘屑通过第一螺旋板的开口进入粉尘收集腔，将尘屑抛向粉尘收集腔中远离第一螺旋板的一端，实现尘屑与气体的分离，尘屑不断在粉尘收集腔内聚集，气体与尘屑分离后，气体在动力部件的作用下进入第一过滤器12。
进一步的，第一螺旋板环绕第一筒体14为1周或大于1周小于1.5周。第一螺旋板环绕第一筒体14至少一周，可以确保第一螺旋板的首端和末端在周向上没有缺口，该过滤装置倒置时，进入粉尘收集腔的尘屑不会重新进入旋风工作腔。
第一螺旋板的开口可以大于第一集尘室11的进风口，尘屑随着气流沿第一进风通道进入第一集尘室11后，按照螺旋的轨迹运动，在离心力的作用下，尘屑会有一定的分散，其散布的范围会大于进风口的大小。因此，开口大于进风口，有利于将尘屑抛入粉尘收集腔，提高析尘能力。
一种优选的实施方式中，第二筒体24的外侧设有第二螺旋板23，第二螺旋板23靠近第二过滤器22的底部，如图11和图12所示。
进入第一集尘室11内部，即进入了第二集尘室21的气流，向第二过滤器22所在的位置移动，移动过程中，经过第二螺旋板23，使气流再次按照螺旋的方式移动，气流内的尘屑在离心力的作用下靠近第一筒体14的内壁，并沿着内壁运动，使尘屑远离第二过滤器22，螺旋气流将尘屑向远处推送的过程中，很容易将尘屑甩出气流，留在第二集尘室21中，提高第二级过滤过程中的除尘效率，并且延长第二过滤器22的使用寿命。
第二螺旋板23环绕第二筒体24至少为1周的90％，相当于形成了螺旋风道；第二螺旋板23环绕第二筒体24越长，螺旋风道形成的螺旋风的趋势越强，但是，会占用较大的体积，优选的，第二螺旋板23环绕第二筒体24为1周或大于1周小于1.5周。
进一步优选的实施方式中，第二过滤器22的顶部的外侧设有第三螺旋板33，第三螺旋板33的螺旋方向与第二螺旋板23的螺旋方向相同，如图11和图12所示。
第三螺旋板33能够起到与第一螺旋板类似的作用，在第二集尘室21中分隔出一个收集尘屑的腔室，实现尘屑与气体的分离，然后气体在动力部件的作用下进入第二过滤器22。
上述各实施方式中，第二过滤器22和第二筒体24的内部形成第三集尘室，设有第三过滤器，第三过滤器与出风口连通。
该过滤装置可以按照类似的方式设置第三级过滤器，或更多级的过滤器，对气体进行多级过滤，进一步提高除尘效率。
具体的，可以根据实际使用的需要，设定过滤装置过滤的级数，在除尘效率要求较高的场合，使用具有多级过滤器的过滤装置。
上述各具体的实施方式中，出风口位于第一集尘室11的底部或顶部。
气流经进风通道进入第一集尘室11后，甩掉一部分尘屑，经过第一过滤器12的过滤，进入第二集尘室21，再甩掉一部分尘屑，经过第二过滤器22过滤，通过出风口，经动力部件流出。
动力部件的位置并不影响气流在过滤装置内的运动，动力部件与出风口连通，启动时能够使第一集尘室11和第二集尘室21均产生负压即可，所以，出风口可以设置在第一集尘室11的底部，如图12所示，也可以设 置在第一集尘室11的顶部。
除了上述过滤装置，本发明还提供了一种除尘设备，包括动力部件和上述各实施例所述的过滤装置，所述动力部件位于出风口内，气流进入所述过滤装置的过滤器后流向动力部件。
该过滤装置具有上述技术效果，故具有该过滤装置的除尘设备也具有相应的技术效果。除尘设备其他各部分的结构请参考现有技术，本文不再赘述。
以上对本发明所提供的过滤装置及除尘设备进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
