下面参考图1-图6描述根据本发明实施例的泄压装置100。
如图1-图6示，根据本发明一个实施例的泄压装置100包括：外壳10和活动件20。
外壳10内具有出水通道12和多个进水通道13，出水通道12与至少一个进水通道13之间设有连通口11，活动件20设置在出水通道12内，且活动件20可以在初始状态与泄压状态之间切换。
当活动件20处于初始状态时，活动件20可以封堵连通口11，从而使进水通道13和出水通道12不连通，即进水通道13和出水通道12可以单独过水，水源的水可以通过进水通道13流入采用该泄压装置100的设备内，该设备内的水可以通过出水通道12排出到外界；当活动件20处于泄压状态时，活动件20打开连通口11，从而可以使进水通道13和出水通道12连通，即进水通道13内的水压过大时，可以通过进水通道13与出水通道12的连通，使高压水向低压方向流动，当进水通道13与出水通道12内部的压力相等时完成泄压。
根据本发明实施例的泄压装置100，通过将多个进水通道13和出水通道12集成在外壳10内，使得泄压装置100可以实现水路的分流作用，为用户提供更多利益；并通过设置连通口13使得各通道内压力可以整合到一起实现过载泄压，减少了传统泄压装置的使用数量，提高了空间利用率；且该结构简单紧凑，便于安装至任何设备中，提高了泄压装置100的通用性，用户体验好。
根据本发明的一个实施例，在进水通道13内的压力大于预定压力时，活动件20打开连通口11，使进水通道13和出水通道12连通，出水通道12与外界连通，因而始终处于常压状态，进水通道13内的压力大于常压，利用出水通道12相对的低压，使进水通道13内的高压水向出水通道12方向流动，从而实现泄压。
根据本发明的一个实施例，活动件20包括：封堵部21和弹性件22，封堵部21用于打开和封堵连通口11，弹性件22与封堵部21连接，且当活动件20处于初始状态时，在弹性件22的压力作用下，封堵部21被压设在连通口11处，从而将连通口11封堵，使得进水通道13和出水通道12不导通，进水通道13和出水通道12可以单独过水；当活动件20处于泄压状态时，封堵部21打开连通口11，使进水通道13与出水通道12连通。
进一步地，当进水通道13内的压力大于弹性件22的弹力时，压力推动封堵部21克服弹性件22的弹力，封堵部21在进水通道13内的压力作用下活动，从而可以打开连通口11，使进水通道13与出水通道12实现连通。
由于出水通道12直接与外界大气连接，压力远远小于进水通道13内的压力，当进水通道13与出水通道12连通后，高压水会向低压方向流动，当进水通道13与出水通道12内部的压力相等时完成泄压工作；此时，封堵部21在弹性件22的弹力作用下再一次压设在连通口11处，活动件20恢复到初始状态；当进水通道13内部压力再一次升高后，可以反复进行泄压。
如图6所示，在一些示例中，出水通道12内设有限位腔18，限位腔18环绕连通口11设置，以促使进水通道13与出水通道12通过限位腔18连接。封堵部21适于在限位 腔18内活动，以避免封堵部21在初始状态和泄压状态切换时，偏离连通口11，导致无法封堵连通口11而造成泄压装置100失效。
具体地，出水通道12内设有限位凸环，限位凸环环绕连通口11，以促使进水通道13与出水通道12通过限位凸环连接，同时在连通口11处形成环绕其的限位腔18。
在进一步的示例中，封堵部21形成柱状，限位腔18也形成柱状，限位腔18的轴向长度大于封堵部21的轴向长度，进一步保证封堵部21在活动时始终位于限位腔18内，而不会偏离连通口11，避免了连通口11无法被封堵而导致泄压装置100分流失效。
根据本发明的一个实施例，外壳10内设有隔板19，连通口11设置在隔板19上，隔板19可以将进水通道13和出水通道12隔开，使得进水通道13和出水通道12互不导通，从而实现泄压装置100的分流。
如图5所示，在一些示例中，活动件20的朝向隔板19的一端设有密封件40，当活动件20移动时，密封件40随活动件20同步移动，当活动件20处于初始状态时、活动件20封堵连通口11，此时密封件40与隔板19止抵连接，从而保证连通口11处的密封性，避免出水通道12与进水通道13在该状态下导通，影响泄压装置100的分流效果。
根据本发明的一个实施例，外壳10包括：壳体14，端盖17，进水通道13和出水通道12形成在壳体14内，且壳体14具有与出水通道12连通的开口，端盖17通过螺钉可拆卸地设置在开口处，端盖17用于打开和关闭开口，活动件20安装在端盖17的朝向壳体14的一侧。由于泄压装置100长时间使用，泄压装置100内部会沉积一定的杂质，通过设置端盖17，当拆卸端盖17上的螺钉，取出端盖17和活动件20后，可以对泄压装置100内部进行清洗，拆卸方便、清洗简单且效果好，进而可以提高泄压装置100的分流和泄压性能。
根据本发明的一个实施例，外壳10包括：第一罩壳15和第二罩壳16，第一罩壳15和第二罩壳16密封连接，从而可以限定出出水通道12和进水通道13，其中，出水通道12和/或进水通道13的一部分位于第一罩壳15内，出水通道12和/或进水通道13的另一部分位于第二罩壳16内。
具体地，第一罩壳15和第二罩壳16采用固定连接的方式，从而形成封闭的空腔，通过在空腔内设置多个隔板19，使外壳10内形成出水通道12和进水通道13，实现泄压装置100的分流。
根据本发明的一个实施例，进水通道13和活动件20分别包括多个，且进水通道13的数量大于或者等于活动件20的数量。
如图2所示，泄压装置100内具有两个活动件，两个活动件20上下排布，并且两个活动件20相互独立不受影响，一个活动件20将一个进水通道13与出水通道12连通 或封堵，另一个活动件20将另一个进水通道13与出水通道12连通或封堵，从而可以实现两个进水通道13的泄压。
根据本发明实施例的衣物处理装置，包括根据本发明实施例的泄压装置，通过采用上述泄压装置100，减少了衣物处理装置内泄压装置100的使用数量，提高了空间利用率，同时保证了在内部气压增大时可以及时泄压，避免了零部件损坏的情况，提高了衣物处理装置的使用寿命，用户体验好。
下面结合图1-图6描述根据本发明的衣物处理装置的一个具体的实施例。
衣物处理装置限定有衣物处理腔，衣物处理腔具有三个进水接口和一个排水接口以及一个泄压装置100，泄压装置100包括外壳10和两个活动件20。
外壳10包括壳体14和端盖17，壳体14内具有隔板19，隔板19将壳体14的内腔分隔成出水通道12和三个进水通道13，三个进水通道13的一端分别水源连接，三个进水通道13的另一端与进水接口一一对应连接，以将水源的水引入衣物处理腔内，出水通道12的一端与排水接口连接，出水通道12的另一端与外界连通，以将衣物处理腔内的水排出。出水通道12的一部分沿前后方向延伸，另一部分沿上下方向延伸；同样，每个进水通道13的一部分沿前后方向延伸，另一部分沿上下方向延伸。
出水通道12内设有限位凸环，该限位凸环限定出限位腔18，限位凸环的一端与隔板19固定连接，且该限位凸环围绕的隔板19上设有连通口11，该连通口11可以将出水流道12和一个进水流道13连通。
活动件20位于出水通道12内，每个活动件20均包括封堵部21和弹性件22，弹性件22的一端与端盖17固定连接，另一端与封堵部21固定连接，弹性件22可以带动封堵部21沿水平方向(如图5中所示的左右方向)移动，封堵部21远离弹性件22的一端还设有密封件40。
初始状态时，封堵部21在弹性件22的弹力作用下，带动密封件40右移并压设在隔板19上，使得隔板19两侧的进水通道13和出水通道12不连通。外界水源分别可以通过三个进水通道13进入衣物处理腔，衣物处理腔内的废水通过出水通道12排出。
当一个进水通道13内部水压升高，直至该水压大于弹性件22的弹力时，水压推动封堵部21克服弹性件22的弹力向左移动，从而使得进水通道13和出水通道12连通，进水通道13内的高压水会向出水通道12内流动，实现泄压。
当进水通道13与出水通道12内部的压力相等时完成泄压工作，此时，封堵部21在弹性件22的弹力作用下再一次右移，使得密封件40再次压设在隔板19上，活动件20恢复到初始状态；当进水通道13内部压力再一次升高后，可以反复进行上述泄压。
