具体实施方式
下文结合附图和具体实施方式对本发明做进一步说明。
实施例1参考图1-5一种按压开关出水结构，包括：本体1、密封组件2和按压开关组件3；
所述本体1具有进水口11和出水口12，以及连通进水口11和出水口12的出水流道；所述密封组件2安装在本体1内，并在本体1内腔形成一个压力腔13；还具有一连通所述压力腔13和出水流道的泄压孔21；所述本体1还具有一连通压力腔13的进水孔18；
所述按压开关组件3带动一密封杆31沿着轴向往复运动，使其在第一位置和第二位置之间运动；当密封杆31位于第一位置时，所述泄 压孔21被密封杆31密封，压力腔13中的水压增大，密封组件2被水压推动至密封位置将所述出水流道关闭，同时密封组件2挤压复位组件4积累弹性复位力；当所述密封杆31位于第二位置时，所述泄压孔21被密封杆31打开，压力腔13中的水压减小，此时密封组件2受到向上的进水压力，进水压力和复位组件4的复位力带动密封组件2复位将所述出水流道打开。这样就完成了止水和开水两个过程。当所述密封杆从第一位置移动至第二位置时，所述密封组件2的内圈保持静止固定，外圈发生形变以打开所述出水流道。
需要说明的是，复位组件4是在低压情况下辅助打开密封组件2的，如果水压是正常的状态下，去除复位组件4仅仅依靠水压差也是可以将密封组件2打开的。
本实施例中，所述出水口12设置在本体1的下端面；所述进水口11设置在本体1的侧壁下端。使得出水口12和进水口11形成类似一个同心圆的嵌套分布，二者可以位于同一水平面内，相对于传统的将进水口11和出水口12上下排布，这种排布方式可以降低出水控制阀芯的整体高度。
具体来看本实施例的结构：所述本体1包括一外壳14和底座15，所述出水口12设置在底座15，所述出水口12设置在15和外壳14的侧壁之间。也就是说外壳14的底面为开口面，底座15放置在开口面处时，底座15的边缘和外壳侧壁的边缘形成一定空隙，这个空隙就形成了进水口11。
为了实现密封组件2对出水通道的关闭，所述本体1的下端面，也 就是底座15在进水口11和出水口12之间的区域沿着轴向向上延伸形成一圈凸缘151；当所述密封杆31位于第一位置时，所述密封组件2的下端面与所述凸缘151顶抵贴合，将出水流道关闭。
为了实现密封杆31密封泄压孔21，所述泄压孔21处设置有密封圈22，当所述密封杆31位于第一位置时.密封杆31的侧壁与所述密封圈22贴合将所述泄压孔21密封。
对于泄压孔21的设置，本发明采用了如下所述的结构，所述本体1内设置有密封组件2安装座16，所述安装座16具有沿着轴向设置的贯穿开口，并且所述贯穿开口的内壁沿着径向向内延伸形成放置所述密封圈的平台163，密封圈22就放置在平台163上，从而形成泄压孔21。密封杆31具有沿着轴向设置的第一部分和第二部分，其中第一部分的直径小于第二部分，当密封杆31位于第一位置时，第二部分运动至密封圈22中，使得第二部分与密封圈22的内周贴合，从而关闭了泄压孔21。而当密封杆31位于第二位置时，第一部分运动至密封圈22中，由于第一部分的直径小于第二部分，这样密封杆31与密封圈22的内壁就解除了贴合的状态，泄压孔21被打开。
本实施例中，所述密封组件2包括皮碗23、皮碗支撑件24和顶杆25；所述皮碗23包括内圈231和U形外圈232，所述U形外圈232上部为U形部233，下部为Y形部234(剖面形状)；所述安装座16分为上座161和下座162，所述皮碗23的内圈231被夹持固定在上座161和下座162之间；Y形部234的内侧镶嵌有支撑件24，形成移动部；U形部233为变形部；U形外圈232的侧壁与本体1的内壁密接。
所述皮碗支撑件24的上表面与皮碗23的U形外圈的下表面顶抵支撑，下表面延伸至皮碗23外。皮碗支撑件24的作用除了对U形外圈提供支撑外，还通过暴露在皮碗23外的部分与顶杆25抵接，而顶杆25与复位组件4联动设置，这样在复位组件带动顶杆25复位时，顶杆25就会推动皮碗支撑件24，又因为皮碗23的内圈被夹持固定在上座161和下座162之间，所以皮碗23的整体位置是不会变化的，顶杆25对U形外圈的作用力和进水压力只会使得U形外圈的高度发生改变，从而实现皮碗23与凸缘151的分离。这种方式皮碗无需发生移动，因此进一步缩小了阀芯的高度。
本实施例中，所述顶杆25的一部分伸入所述贯穿开口中，另一部分沿着径向张开与所述皮碗23支撑件暴露在皮碗23外的部分抵接。
本实施例中，所述底座15包括座体152、定位套153，座体152向上延伸一凸缘151，凸缘151上端面内接定位套153；凸缘151上端面与定位套153下端镂空连接，凸缘151上端面与定位套153上端面设有轴向一间距，定位套153的壁体上还开有导向槽155；座体152的外侧壁设有卡块153、154。
所述底座15通过其座体152的外侧壁上卡快153、154与外壳14卡接，密封组件2设置在底座15上方，安装座的下座162抵靠在定位套153上端面。密封杆31位于第一位置时，皮碗23的Y形圈密接外壳14内壁与凸缘151之间，关闭出水流道。密封杆31位于第二位置时，泄压孔21打开，皮碗23的下端Y形部受到向上的进水压力，向上位移，离开凸缘151，水流通过凸缘151上端镂空部流向座体152内，出水。 此时，皮碗23内支撑件24同步位移，其U形部受压变形。
本实施例中，所述顶杆25上端由定位套153伸出，顶杆25下部的横杆251限定在导向槽155内，在复位组件4的复位弹簧41的作用下，向上位移，推动支撑件24。
所述按压开关组件3包括按钮、上棘轮和下棘轮、所述密封杆31与下棘轮连动配合。按钮、上棘轮和下棘轮构成了圆珠笔按压切换机构，从而实现循环切换。圆珠笔按压切换机构属于现有技术中广泛应用的，在本文中不做更多描述。
实施例2
参考图6和图7，一种按压开关出水结构，本实施例与实施例1的区别在于取消了复位组件4和顶杆25。在开水状态时，此时棘轮及密封杆31处于上行位置，密封杆31上有凹面与密封圈22不密封，压力腔13的水压释放，此时密封组件2受到向上的进水压力，密封组件2因上下压力差影响，皮碗23下方水压大于压力腔13的水压，受水压向上推力，密封组件2通过U形外圈变形上行，密封组件2离开底座密封面，即处于开水状态。
在关水状态时，此时按压使密封杆31下行，密封杆31与密封圈22形成密封，内压腔水压瞬间增加，密封组件2在U形外圈变形复位力作用下，密封组件2将向下移动与凸缘151密封至关闭，此时密封组件2上方受水压面积大于下方面积，阀芯关闭。
实施例3，参考图1-9，一种恒温淋浴器，包括外壳、热水进水口、冷水进水口、第一混合水出水口和第二混合水出水口；外壳内放置了出 水控制阀芯01，分别用于将第一混合水出水口和第二混合水出水口打开或者关闭，从而实现出水控制。本发明地恒温淋浴器控制部分的宽度非常小，这是因为上述的出水控制阀芯地高度很小，本实施例外壳的截面尺寸可以是40*50。
本实施例出水控制阀芯01采用实施1或实施2的按压开关出水结构。本实施例以恒温淋浴器进行举例，但是本发明的改进之处在于按压开关出水结构，以恒温淋浴器仅是为了更好地说明本发明的有益效果，其他的出水终端中依然可以使用本实施例的按压开关出水结构，因此不能以此限定本发明的保护范围。
本发明按压开关出水结构也可用于厨房出水终端。
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。
工业实用性
本发明一种按压开关出水结构，其密封组件的皮碗内圈是固定的依靠水压或者弹性复位件的作用来改变皮碗U形外圈的高度，从而使得皮碗的下端面密封或打开出水流道，这样可以最大限度减小按压开关的行程，阀芯的高度尺寸就可以尽可能做小，可广泛用于花洒、龙头等卫厨出水终端，具有良好的工业实用性。
