为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白,以下结合附图和实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本发明,并不用于限定本发明。
实施例一
如图1、图2所示,本发明所述的分体式排水机构,包括箱体1、导杆2、第一活塞3、第一活塞加载弹簧4;其中,箱体1具有相互连接的箱壁1-1和箱底1-2,箱壁1-1与箱底1-2一体成型或连成一体,该箱壁1-1限定一个柱形结构,导杆2顺着所述轴线在箱体1内沿轴向固定,
在箱底1-1环绕导杆2开设一用于连接冲水管路(图中未示出)的出水口。
导杆2包括螺杆和螺帽,螺帽限定一个轴向螺孔,螺杆可旋入该轴向螺孔;第一活塞3可沿导杆2轴线方向密封滑动。该第一活塞3将箱体1的内腔室分隔成一个上腔室1-3及一个下腔室1-4,下腔室1-4接触箱底1-2,上腔室1-3则与下腔室1-4相对。第一活塞3包括活塞上部与活塞底部,活塞上部沿轴线方向向上延伸并呈中空圆柱状结构,活塞上部安装于导杆2的外壁,活塞底部的外径略小于箱壁1-1的内径,活塞底部可沿箱壁1-1的内壁上下密封滑动;优选的,第一活塞加载弹簧4环绕导杆2安装,且向第一活塞3施加弹性力以驱动第一活塞3趋于向下移动,从而缩小下腔室1-4的容积并扩大上腔室1-3的容积。
如图1、图2所示,本发明所述的分体式排水机构还包括第二活塞5、第二活塞加载弹簧6;第二活塞5可沿轴线方向在导杆2上密封滑动,该第二活塞5
底部外周壁上设有大密封圈5-1,该第二活塞5位于第一活塞3与箱底1-2之间。第二活塞5同样包括活塞上部与活塞底部,活塞上部呈中空的圆柱形结构且套设于导杆2的外周壁,活塞沿轴线方向在导杆2上密封滑动;第二活塞加载弹簧6环绕所述导杆2安装,用于对第二活塞5施加弹性力以驱动第二活塞5趋于向上移动。
如图1、图2所示,
第二活塞5与箱底1-2之间设有可沿第二活塞5的轴向部分上下滑动的内嵌套管7,内嵌套管7底部外周壁上可以设有小密封圈7-1。内嵌套管7、第二活塞5及箱底1-2之间形成环形外密封腔5-3,
该环形密封腔5-3通过内嵌套管7的移动实现与出水口的连通或封闭。第一活塞3上设有第一作用元件3-2,内嵌套管7上设有与第一作用元件3-2相互作用的第二作用元件7-2,
第一作用元件3-2与第二作用元件7-2的相互作用以实现内嵌套管7的移动。内嵌套管7与第二活塞5之间可以设有使内嵌套管7趋于向下移动的复位弹簧7-3。内嵌套管7上设有小密封圈7-1,小密封圈7-1随内嵌套管7一起移动且用于密封箱底1-2。在本实施例中,第一作用元件3-2与第二作用元件7-2中之一元件为磁性材料制成的磁力元件,另一件为磁性材料制成的磁力元件或由金属材料制成的金属元件,第一作用元件3-2与第二作用元件7-2相互吸引。
下面结合附图1-5说明本发明所述的分体式排水机构的进水与排水过程。
图1、图2示出了分体式排水机构初始状态。此时第一活塞3位于箱底1-2(下止位置),第一活塞3挤压第二活塞5使第二活塞5也位于其下止位置,第二活塞5上的大密封圈5-1与箱底1-2密封。内嵌套管7位于第二活塞5与箱底1-2之间,内嵌套管7受第一作用元件3-2与第二作用元件7-2相互作用而处于上止位置,此时,内嵌套管7与箱底1-2未实现密封,环形外密封腔5-3与出水口连通。
图3示出了分体式排水机构进水状态。开启控制开关(图中未示出),水流进入下腔室1-4,水压克服第一活塞加载弹簧4的弹性力而将第一活塞3往上推动。在水压作用下,第二活塞5继续停留在下止位置,第二活塞5上的大密封圈5-1继续与箱底1-2密封。第一作用元件3-2与第二作用元件7-2之间的相互磁力作用由于相对距离的增大而减小,内嵌套管7由于自身重力及弹簧弹力作用而向下移动,内嵌套管7与箱底1-2也实现密封状态。
第一活塞3往上移动过程中,第一作用元件3-2与第二作用元件7-2之间的相互磁力作用减小,复位弹簧7-3开始复位,并且复位弹力也使内嵌套管7往下移动,内嵌套管7上的小密封圈7-1与箱底1-2密封,从而使环形外密封腔5-3与出水口密封。另外,内嵌套管7上如设有小密封圈7-1,则小密封圈7-1加强了与箱底1-2的密封性。
图4、图5示出了分体式排水机构排水状态。当控制开关控制箱体1进行排水时,压力水进入环形密封腔5-3,水压力及第二活塞加载弹簧6弹力将第二活塞3及内嵌套管7顶起向上移动。同时,由于下腔室1-4的水量逐渐减少,第一活塞加载弹簧4的弹性力将第一活塞3往下推动。最终,第一活塞3与第二活塞5靠近。由于第一作用元件3-2与第二作用元件7-2之间的相互吸引力增大,从而使内嵌套管7相对第二活塞5向上移动。因此,当第二活塞5的大密封圈5-1与箱底1-2实现密封时,内嵌套管7(或者内嵌套管7上的小密封圈7-1)还没有与箱底1-2实现密封,环形外密封腔5-3的水则可以从小密封圈7-1与出水口之间的通道流出实现排水,避免环形外密封腔5-3内储有较大水压而造成第二活塞5再次开启。
如上所述,第一活塞3往下移动,第二活塞5上的大密封圈5-1与箱底1-2实现密封后,第一作用元件3-2与第二作用元件7-2相互作用使内嵌套管7往上移动并压缩复位弹簧7-3。
实施例二
如图6、图7所示,本实施例与实施例一的区别在于,实现内嵌套管7上下移动时的第一作用元件3-2与第二作用元件7-2的实施方式不同。本实施例的第一作用元件3-2为设置于第一活塞3底部的第一插杆3-2-2,第二作用元件7-2为固定于第二活塞5上的杠杆结构7-2-1,该杠杆结构7-2-1的第二侧向下延伸出第二插杆7-2-2并且该第二插杆7-2-2固接于内嵌套管7上,该第一插杆3-2-2向下移动时将杠杆结构7-2-1的第一侧往下压从而使第二插杆7-2-2带动内嵌套管7往上移动。杠杆结构7-2-1第一侧设有用于容置第一插杆3-2-2的插孔6-2-2,第一活塞3向上移动时,第一插杆3-2-2可脱离于杠杆结构7-2-1的插孔6-2-2。
实施例三
如图8、图9所示,本实施例与实施例一的区别在于,也是实现内嵌套管7上下移动时的第一作用元件3-2与第二作用元件7-2的实施方式不同。第一作用元件3-2为设置于第一活塞3底部的第一齿条3-2-2',第二作用元件7-2为一固定于第二活塞5上的齿轮结构7-2-1',该齿轮结构7-2-1'的一侧向下延伸出第二齿条7-2-2'并且该第二齿条7-2-2'固接于内嵌套管7上,该第一齿条3-2-2'向下移动时啮合带动齿轮结构7-2-1'旋转从而使第二齿条7-2-2'带动内嵌套管7往上移动。
上述说明示出并描述了本发明的优选实施例,如前所述,应当理解本发明并非局限于本文所披露的形式,不应看作是对其他实施例的排除,而可用于各种其他组合、修改和环境,并能够在本文所述发明构想范围内,通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围,则都应在本发明所附权利要求的保护范围内。
本发明所述的分体式排水机构,用于实现第一活塞、第二活塞与箱底密封的大密封圈与内嵌套管(或者内嵌套管上的小密封圈)分别位于不同的组件上,从而可以实现大密封圈与小密封圈的相对位移及密封时序的控制,而不需要利用大密封圈与小密封圈的材料特性(如压缩变形)等来实现,从而增强了排水机构排水的稳定性,以及延长了大密封圈与小密封圈的使用寿命。
