具体实施方式
以下结合附图及实施例对本发明作进一步详细说明；但本发明的检测和修锐装置不局限于实施例。
参考图1-4，一种水路切换阀，包括：阀体1、切换操作件2、切换件3；
所述阀体1具有一进水口14和第一出水口15、第二出水口16；所述切换操作件2与切换件3连动设置，所述切换件3沿着自身移动方向依次设置有第一密封件31、第一泄压件32、第二泄压件33和第二密封件34；
所述阀体1内沿着切换件3的移动方向设置有第一压力形成腔11和第二压力形成腔12；所述阀体1内在第一压力形成腔11和第二压力形成腔12之间设置有一封堵件13；所述封堵件13具有相互隔离的第一流道131和第二流道132，第一流道131和第二流道132分别连通至第一出水口15和第二出水口16；
所述第一压力形成腔11和第二压力形成腔12中具有开口，所述切换件3穿过所述开口。
因此，上述的一种水路切换阀，通过切换操作件2带动切换件3移动，当切换操作件2带动切换件3移动至所述第一密封件31与第一压力形成腔11的开口对应的位置时，所述第一压力形成腔11为憋压状态，水压驱动第一压力形成腔11与封堵件13的上端面贴合密封，第一出水 口15与进水口14隔开；当切换操作件2带动切换件3移动至所述第一泄压件32与第一压力形成腔11的开口对应的位置时，所述第一压力形成腔11为泄压状态，第一压力形成腔11与封堵件13的上端面分离，第一出水口15与进水口14连通。
对于这样的水路切换阀，可以设计成，当第一出水口15与进水口14连通的时候，第二密封件34与第二压力形成腔12的开口密封，这样第二出水口16与进水口14被隔开。反之当第一出水口15与进水口14隔开的时候，第二泄压件33与第二压力形成腔12的开口对应，这样第二出水口16与进水口14连通。也就是说水路切换阀一共就两种出水状态，第一出水口15和第二出水口16中有且只有一个出水，是一种两档出水的水路切换阀。
当然作为上述结构的简单替换。本实施例中也可以增加设置第一出水口15、第二出水口16同时出水或者同时不出水的挡位，从而形成三档或四档出水的水路切换阀。
本实施例中，所述切换件3为切换杆，所述切换杆的轴向侧壁上设有两段内凹部，这样就使得切换杆上有的部位直径比较大，有的部分直径比较小。直径大的部分就形成所述第一密封件31、第二密封件34；直径小的部分形成所述第一泄压件32和第二泄压件33。利用不同位置的粗细不同，就可以实现对封堵开口或者打开开口。
下文针对阀体1的结构做出具体的描述，所述第一出水口15和第二出水口16沿着切换件3的自身移动方向上下放置；所述进水口14位于 第一出水口15和第二出水口16之间。
所述封堵件13的外壁与阀体1的内壁之间形成进水流道。这样水从进水口14流入阀体1后，遇到封堵件13的外壁后就分成两股，分别沿着封堵件13的外壁向上向下流动。
所述第一流道131和第二流道132沿着切换件3的自身移动方向上下放置；所述封堵件13还具有一连通第一流道131和第二流道132的安装孔；所述切换件3穿过所述安装孔；所述切换件3在第一泄压件32和第二泄压件33之间还具有一第三密封件35；所述切换操作件2带动切换件3移动时，所述第三密封件35始终与所述安装孔密封贴合，使得第一流道131和第二流道132相互隔离。
这样设置后，水流从进水口14流入阀体1后，只能沿着封堵件13的外壁向上向下流动至封堵件13的端面后，才能进入第一流道131或第二流道132。因此，只要将封堵件13的端面进行密封，就可以实现关闭第一流道131或第二流道132，进而关闭第一出水口15或第二出水口16。
因此，为了实现关闭出水口时，密封封堵件13的端面，所述第一压力形成腔11朝向封堵件13上端面的一侧，第二压力形成腔12朝向封堵件13下断面的一侧，分别为一皮碗111、121。如果压力形成腔处于憋压状态，由于压力形成腔中的水压越来越大，就可以推动皮碗111、121向着靠近封堵件13端面的方向运动，从而使得二者紧密贴合。
为了实现打开出水口时，让封堵件13的端面和皮碗111、121分离，所述皮碗111、121上设置一压力腔进水孔，所述第一压力形成腔11和 第二压力形成腔12中分别设置一防堵弹簧112、122，防堵弹簧112、122的一端插入压力腔进水孔中；所述第一压力腔11或第二压力腔12处于憋压状态时，所述皮碗111、121向着靠近封堵件13的方向移动，所述防堵弹簧112、122被拉伸。这样当压力形成腔处于泄压状态时，防堵弹簧112、122的复位力就带动皮碗111、121向着远离封堵件13端面的方向运动，从而使得二者分离。
此外，为了安装上述的皮碗111、121，所述阀体1包括一阀体中座、阀体上座和阀体下座，所述阀体上座和阀体下座分别安装在阀体中座的上端面和下端面，所述皮碗111、121安装在所述阀体中座的上端面和下端面处，并分别与阀体上座和阀体下座内的腔体形成所述第一压力形成腔11和第二压力形成腔12。
本实施例中，所述切换操作件2包括按钮21、平移棘轮22和旋转棘轮23；所述平移棘轮22的一端与所述按钮21连动设置，另一端设置有棘齿；所述旋转棘轮23朝向平移棘轮22的一端也设置有棘齿；所述旋转棘齿的另一端朝向所述切换杆。按压按钮21时，按钮推动平移棘轮22移动，从而使得平移棘轮22的棘齿和旋转棘轮23的棘齿顶抵，产生的顶抵作用力就让旋转棘轮23向着远离平移棘轮的方向移动，并转动一个棘齿。旋转棘轮23移动的过程中与切换杆抵接，这样就带动切换杆沿着自身轴向移动。
如附图5-7所示，本发明一种水路切换阀，为了让用户可以清楚地知道当前水路切换阀所处的档位，还包括一与所述旋转棘轮23连动的指 示件4以及一外壳5。所述指示件4包括：按压转接件41、指示标志件42。按压转接件41与按压按钮21及平移棘轮22固接，指示标志件42与旋转棘轮23固接；
所述阀体1至于外壳5内，所述外壳5的侧壁设置有一透明指示窗51，所述指示标志件42位于所述透明指示窗51的下方；
按压按钮21时，按钮推动平移棘轮22移动，从而使得平移棘轮22的棘齿和旋转棘轮23的棘齿顶抵，产生的顶抵作用力就让旋转棘轮23向着远离平移棘轮的方向移动，并转动一个棘齿；同时，旋转棘轮23带动指示标志件42也相应转动，其位于指示窗51下方的指示标志件42指示标示随之改变。
本实施例中，所述外壳5具有第一管接头54、第二管接头53，其中，第一管接头54内设有进水口14及与第一出水口连通的出水管接头52，第二管接头53与第二出水口连通。
本发明水路切换阀可用于卫浴类产品的水路切换，也可用于厨房终端的水路切换。
以上所述，仅为本发明较佳的具体实施方式，但本发明的设计构思并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，利用此构思对本发明进行非实质性的改动，均属于侵犯本发明保护范围的行为。
