具体实施方式
下文结合附图和具体实施例对本发明做进一步说明。
实施例1
参考图1-5，一种止水切换阀芯，包括阀芯本体1，其侧面设有进水口11、底部设有出水口12；所述进水口11和出水口12连通形成流通道；所述阀芯本体沿着其轴向具备一容置腔；还包括设置于容 置腔内的操作件2、止水件3和出水切换件4；
所述操作件2包括相互独立设置的按压止水件21和旋转切换件22；所述按压止水件21沿着该容置腔的轴向移动，其末端与止水件3的泄压孔31顶抵密封或分离；
所述止水件3为压力盖，其具有一止水腔32，该止水腔32的底部放置一固定座33，其与止水腔32的底部固定连接，共同包围出所述止水腔32；所述固定座33上设置一密封片34，所述流通道中设有向着所述密封片34靠近的封水部13；该固定座33与密封片34在对应位置设有连通所述进水口11和止水腔32的通流孔35；该固定座33上还设有连通出水口12和止水腔32的所述泄压孔31。
因此，当按压止水件21与泄压孔31顶抵密封时，水流从进水口11经通流孔35流入止水腔32中；此时由于泄压孔31被密封，因此密封片34上方的水压大于下方的水压；密封片34在水压的作用下下移与该封水部13顶抵密封。使得水流无法经过流通道后从出水口12中流出，实现了止水。
当按压止水件21与泄压孔31分离时，原本止水腔32中的水从泄压孔31流向流通道中，流通道中的水压大于止水腔32的水压，密封片34在水压的作用下上移与该封水部13分离，水流经过进水口11进入流通道后从出水口12中流出，实现了通水。
所述出水切换件4包括安装于所述出水口12动陶瓷片41和定陶瓷片42；所述动陶瓷片42通过连接套222与旋转切换件22连动设置。所述动陶瓷片41具有一个出水孔，定陶瓷片42具有两个出水口；通过转 动旋转切换件4使得动陶瓷片41的出水孔与定陶瓷片42上不同的出水口连通，选择不同的出水口出水。根据需要，定陶瓷片42上的出水口也可以设置为3个或更多，属于本实施例的简单替换，不再赘述。
所述连接套222上端与旋转切换件22卡接，下端与动陶瓷片42卡接，中部开有与进水孔相适配的孔。
由上可以看出，按压止水件21和旋转切换件22是两组完全独立的组件，互不干涉。因此，用户从通水状态切换为止水状态时，定陶瓷片42和动陶瓷片41的相对位置不会改变，用户再次切换为通水状态时，出水状态依然能够保持为上一次通水状态的出水，无需用户反复进行调整，极大方便了用户的使用，提升了使用体验。
本实施例的技术方案：按压止水件21与旋转切换件22同轴设置在本体内，且按压止水件21位于旋转切换件22内，两组机构是完全独立的组件，互不干涉；由于二者同轴设置本发明结构更紧凑。
通过上述的描述可以知道，从止水切换为通水时，是依靠水对固定座33施加水压从而带动固定座33和密封片34上移。如果水压比较低，就会出现水压不足以带动固定座33上移的情况，也就无法解除密封片34和封水部13的顶抵状态，形成“低压打不开”的情况，稳定性不够好。
为了解决这个情况，本实施例中，所述按压止水件21和所述固定座33设有相互顶抵的提拉部；所述按压止水件21沿着轴向上移的过程中，所述提拉部相互顶抵，使所述按压止水件21带动所述固定座33上移。这就保证了无论是高压还是低压状态下，固定座33都能及时上移，保证出水状态的可靠性。
为了实现按压止水件21的上下移动，所述按压止水件21包括一圆珠笔按压机构211，以及与之连动的压杆212，所述压杆212的末端连接一导向筒213；该导向筒213具有一连通止水腔32的引流腔214，其一端套接在压杆212的末端，另
一端套接在一顶杆215外；所述顶杆215的末端暴露与压杆212外并连接一密封套216。
用户通过反复按压圆珠笔按压机构211，就可以使得按压止水件21的上移和下降。这部分结构属于现有技术，不再赘述。设置引流腔214的目的在于，在止水状态时，引流腔214内也充满水，用于平衡止水腔32中的大部分水压。这样压杆212和密封套216受到的水压就比较小，从止水切换为通水所需的力就比较小。
另一方面，止水状态下，由于柔性的密封片34在和封水部13密封的时候会被压缩，导致固定座33和密封片均有一定程度的下沉，这时候密封密封套216就有可能与泄压孔31分离，造成阀芯“止水时关不住”的情况。为了解决这个问题，所述引流腔214内设置一具有压缩量的弥补弹簧217，用于对顶杆215和密封套216时刻作用一个向下的力，使密封套能在止水时能保持对泄压孔31的顶抵，进而保持阀芯稳定在止水状态。
所述提拉部包括设置在导向筒213外周的第一顶抵块218、以及设置于固定座33上的第二顶抵块331；所述密封套216密封固定座33的泄压孔31时，所述第二顶抵块331位于第一顶抵块218上方，并与其位于同一个竖直平面内。
实施例2
参考图6-8，本实施例与实施例1的区别在于：所述动陶瓷片41和定陶瓷片42分别具有一个出水孔；通过转动旋转切换件22使得动陶瓷片41和定陶瓷片42的出水孔相重合的出水面积发生变化，改变出水口12的出水水量。其余部分与实施例1相同，不再赘述。
实施例3
参考图9-12，本实施例中，所述出水口12和进水口11分别设置于所述阀芯本体1的侧面，并且所述出水口12位于进水口11的上方。并且，所述按压止水件21包括一圆珠笔按压机构211，以及与之连动的运动杆219；运动杆219端设置一密封圈2191；
所述止水腔32设置于进水口11的下方，固定座33设置于该止水腔32的顶端；该运动杆219穿过固定座33后延伸至该止水腔32内；所述按压止水件21处于低位时，该运动杆219沿着轴向下移使其末端的密封圈2191与泄压孔31分离；所述按压止水件21处于高位时，该运动杆219沿着轴向上移使其末端的密封圈2191与泄压孔31顶抵密封。因此其止水和通水的状态与实施例1正好相反。
本实施例中，所述运动杆219的外周与固定座还设有顶抵配合的推压部；所述推压部为运动杆219的外周沿着轴向向外延伸出的第一抵压块2192、以及固定座33上的第二抵压块332；当运动杆219位于止水位置时，该第一抵压块2192位于第二抵压块332的上方；当运动杆219从止水位置下移至通水位置时，第一抵压块2192与第二抵压块332发生顶抵推压，产生的推力将固定座33从止水位置下移至通水位置，因此， 无论水压大或小，都能保证固定座33在需要打开的时候能够及时打开。
与实施例1和2均相同，不再赘述。唯一的区别在于，本实施例中，定陶瓷片42放置在动陶瓷片41靠近进水口的一侧。
