下面结合图1至图2详细描述根据本发明第一方面实施例的逆止高压开关100。逆止高压开关100可以用于净水器、热水器等。
参照图1，根据本发明实施例的逆止高压开关100，包括：阀体1、逆止阀芯(图1中未示出)以及高压开关3。
具体而言，如图1和图2所示，阀体1上设有阀腔11、进水口12和出水口13，进水口12和出水口13分别与阀腔11连通。这样使得从进水口12进入阀腔11内的水流可以经由出水口13流出。所述逆止阀芯设在阀腔11内，所述逆止阀芯构造成使水流从进水口12向出水口13的方向单向流通，而且从出水口13向进水口12的方向截止。这样从进水口12进入阀腔11内的水流可经由出水口13流出，而不能从出水口13流向进水口12，从而能够确保水流的流向。高压开关3与阀体1相连，且高压开关3与阀腔11连通。在水流流过所述逆止阀芯时，通过高压开关3实现水压感应，即当水压到达某个设定值时，通过高压开关3的导向输出信号，用于整机控制。
其中，参照图1，进水口12和出水口13的位置可以互换。水流从进水口12进入阀体1的阀腔11内，经过所述逆止阀芯，并从出水口13流出。因为所述逆止阀芯可使水路单向流动，因此，水流只能单向流过阀腔11。又因为在水流流过所述逆止阀芯时，通过高压开关3实现水压感应，即当水压到达某个设定值时，通过高压开关3的导向输出信号，用于整机控制。
根据本发明实施例的逆止高压开关100，水流从进水口12进入阀体1的阀腔11内，经过所述逆止阀芯，并从出水口13流出。因为所述逆止阀芯可使水路单向流动，因此，水流只能单向流过阀腔11。又因为在水流流过所述逆止阀芯时，通过高压开关3实现水压感应，即当水压到达某个设定值时，通过高压开关3的导向输出信号，用于整机控制。
另外，还使得逆止高压开关100的结构更加紧凑，节省占用空间。
结合图1和图2，根据本发明的一些具体实施例，阀腔11的顶部(例如，图1中阀腔11的上部)敞开并由高压开关3封闭。这样能够将阀体1、所述逆止阀芯以及高压开关3进行整合，使得逆止高压开关100的结构更加紧凑。另外，还可减少零件部件的使用，易于装配。
如图1和图2所示，根据本发明的一些具体实施例，阀体1的顶部设有第一连接部14，第一连接部14水平设置，高压开关3上设有第二连接部31，第二连接部31水平设置，第二连接部31与第一连接部14相对(例如，在图1或图2中第二连接部31与第一连接部14上下相对)，且第一连接部14和第二连接部31螺栓连接。由此，通过第一连接部14和第二连接部31能够实现阀体1与高压开关3之间的可靠连接，还易于拆卸，便于维修保养。
进一步地，结合图1和图2，用于连接第一连接部14和第二连接部31的螺栓4包括多个，且多个螺栓4沿第一连接部14的周缘设置并呈多边形布置。由此，能够进一步确保阀体1与高压开关3之间的连接可靠性，提高逆止高压开关100的使用性能。
其中，多个螺栓4沿第一连接部14的周缘的布置方式可以呈三角形、四边形、五边形、六边形、圆形等。多个螺栓4沿第一连接部14的周缘的布置方式可以根据实际需要适应性设置。
例如，在如图1所示的本发明的实施例中，多个螺栓4沿第一连接部14的周缘的布置方式呈四边形，这样能够确保阀体1与高压开关3之间的连接可靠性。
参照图1和图2，根据本发明的一些具体实施例，阀腔11呈水平延伸的柱状，进水口12和出水口13分别邻近阀腔11的两端(参照图2中阀腔11的左右两端)设置，进水口12和出水口13均呈向下(参照图1或图2中的向下)延伸的管状，且进水口12和出水口13平行。这样便于水的流动，还使得阀体1的结构更加紧凑，节省占用空间。
其中，进水口12和出水口13均呈向下延伸的管状，包括直管、蛇形管、弯管、多通管等。
进一步地，如图1和图2所示，进水口12和出水口13均呈向下延伸的直管状，进水口12和出水口13均呈下部的径向尺寸小于上部的径向尺寸。由此，不仅便于水的流动，还可对水流进行一定的缓冲，从而能够降低噪声，提高阀体1的使用性能。
其中，进水口12与出水口13处均通过密封圈进行水路密封，使得连接不漏水。并且通过多个螺栓4可实现阀体1与高压开关3的连接固定。
参照图1和图2，根据本发明的一些具体实施例，阀体1上设有耳部15，耳部15水平设置，耳部15具有上下延伸(参照图1或图2中的上下方向)的通孔151，耳部15包括间隔设置的多个。由此，易于实现阀体1与其他部件的可靠安装。
进一步地，如图1和图2所示，耳部15包括关于阀体1对称布置的两个。由此，可以平衡受力，使得阀体1与其他部件的连接更加平稳可靠。
例如，在如图2所示的本发明的实施例中，耳部15包括两个，且两个耳部15分别设在阀体1的左右两侧并关于阀体1对称布置。
当然，在本发明的其他实施例中，为了进一步提高阀体1与其他部件的连接可靠性，还可以将耳部15设置成关于阀体1对称布置的四个等。
根据本发明的一些具体实施例，参照图1和图2，高压开关3的接线柱32位于高压开关3的顶部(参照图1或图2中高压开关3的上部)。由此，易于通过接线柱32实现高压开关3与其他零部件的可靠电连接。
其中，水流从进水口12进入阀体1的阀腔11内，经过所述逆止阀芯，并从出水口13 流出。因为所述逆止阀芯可使水路单向流动，因此，水流只能单向流过阀腔11。又因为在水流流过所述逆止阀芯时，通过高压开关3实现水压感应，即当水压到达某个设定值时，通过高压开关3的导向输出信号，用于整机控制。
另外，高压开关3上还可设有多个加强筋33，在如图2所示的本发明的实施例中，加强筋33包括两个，且两个加强筋33对称布置在高压开关3的左右两侧，从而提高高压开关3的使用可靠性。
此外，根据本发明实施例的逆止高压开关100还可用于其它水路部件与TDS探针的集成化，这样可以进一步扩大逆止高压开关100的适用范围。其中，TDS是英文total dissolved solids的缩写，中文译名为溶解的固体总量，测量单位为毫克/升(mg/L),它表明1升水中溶有多少毫克固体杂质。它包含无机盐和有机物的总量。通过检测溶解性总固体,可以分析水质的总矿化度。TDS值代表了水中溶解物的杂质含量，TDS值越大，说明水中的杂质含量越多，反之，杂质含量越少。
下面参考图3描述根据本发明另一个实施例的逆止高压开关100。
如图3所示，根据本发明实施例的逆止高压开关100，包括阀体1，阀体1内集成有用于检测水压的压力感应阀芯2和用于水流单向流通的逆止阀芯30。
例如，在图3的示例中，压力感应阀芯2设在阀体1的上部，当水流从逆止高压开关100内部流过时，压力感应阀芯2可以检测逆止高压开关100内部的水压，且在水压达到压力感应阀芯2的感应范围时，压力感应阀芯2输出感应信号。
逆止阀芯30设在阀体1的右侧，使得水流从逆止高压开关100的一端(例如图3中逆止高压开关100的右端)流向逆止高压开关100的另一端(例如图3中逆止高压开关100的左端)。可以理解的是，压力感应阀芯2和逆止阀芯30在阀体1内的布置方式等可以根据实际要求而适应性调整，本发明对此不作特殊限定。
根据本发明实施例的逆止高压开关100，通过将压力感应阀芯2和逆止阀芯30设在阀体1的内部，将单向阀与高压开关集成为一体，由此，减小了元件的占用空间，并减少了元件之间的接头数量，从而降低了漏水的风险，提高了逆止高压开关100的可靠性及安全性。
根据本发明的一个实施例，参照图3，阀体1包括阀体主体110和与阀体主体110相连的插脚120，阀体主体110内形成有水流通道，且插脚120上形成有连通水流通道的进水口或出水口，插脚120为一个或间隔布置的多个。
例如，如图3所示，阀体主体110位于阀体1的上部，插脚120与阀体主体110相连，且插脚120为间隔布置的两个，上述两个插脚120相互平行，并位于阀体主体110的同侧 (例如图3中阀体主体110的下侧)。上述两个插脚120中的一个插脚120(例如图3中右侧的插脚120)的端部形成有进水口，上述两个插脚120中的另一个插脚120(例如图3中左侧的插脚120)的端部形成有出水口。水流从上述进水口进入阀体主体110内的水流通道，并从上述出水口流出，结构简单，便于实现。
在使用时，可将插脚120插接于安装部位，由此，可将逆止高压开关100固定在相应的位置处，操作简单，安装方便。此外，可根据实际需要，灵活调整插脚120的数量及进水口和出水口的位置。
例如，当插脚120为一个时，进水口可以形成在插脚120的一端(例如图3中插脚120的下端)，出水口可以形成在阀体主体110的远离插脚120的一端，水流从插脚120的的下端流向阀体主体110。
当插脚120为多个时，多个插脚120中的一部分插脚120的端面上形成有进水口，多个插脚120中的另外一部分插脚120的端面上形成有出水口。水流从形成有进水口的一部分插脚120的端面流向阀体主体110，再从形成有出水口的另一部分插脚120的端面流出。
进一步地，插脚120的周壁上形成有密封圈槽121，密封圈槽121为一个或沿插脚120的长度方向间隔布置的多个。例如，在图3的示例中，密封圈槽121为两个，且沿插脚120的长度方向间隔设置。其中，密封圈槽121可以形成在插脚120的外周面上，也可以形成在插脚120的内周面上，本发明对此不作具体限定。由此，可在使用时，将密封圈安装在密封圈槽121内，从而可以防止逆止高压开关100漏水，提高了逆止高压开关100的可靠性。
可选地，密封圈槽121设在插脚120的外周面上并邻近插脚120的自由端。具体而言，密封圈槽121邻近插脚120的下端，如图3所示。由此，可方便地将密封圈安装在密封圈槽121内，便于将插脚120插接在安装部位，提高了安装效率且结构简单，便于实现。
可选地，压力感应阀芯2设在阀体主体110内，且逆止阀芯30设在具有进水口的插脚120内，但不限于此。例如，在图3的示例中，压力感应阀芯2设在阀体主体110的中部，右侧的插脚120的下端设有进水口，左侧的插脚120的下端设有出水口，单向阀体1设在具有进水口的右侧的插脚120内。水流从右侧的插脚120进入阀体1后，经过压力感应阀芯2，再从左侧的插脚120下端的出水口流出。
进一步地，逆止高压开关100上设有用于压力感应阀芯2连接电源的电源接线端口40，压力感应阀芯2邻近电源接线端口40设置。如图3所示，电源接线端口40为两个，且形成在阀体主体110的上方。水流在逆止高压开关100内部流过，当水流的水压达到压力感应阀芯2的感应范围时，压力感应阀芯2输出感应信号，并将感应信号通过电源接线端口40输出，以使整机执行相应的动作。由此，可便于感应信号的输出。
更进一步地，阀体1的外表面上设有螺钉柱5，螺钉柱5为一个或多个。例如，在图3的示例中，插脚120的中下部分别设有一个螺钉柱5。在安装时，可先将插脚120插接在安装部位，再将螺钉柱5连接在安装部位，由此，进一步地增加了逆止高压开关100连接的牢靠性。
根据本发明的一个具体实施例，如图3所示，逆止高压开关100包括阀体1，阀体1包括阀体主体110和与阀体主体110连接且位于阀体主体110下侧的相互平行的两个插脚120，其中阀体主体110右侧的插脚120的下端形成有进水口，阀体主体110左侧的插脚120的下端形成有出水口。阀体主体110内设有压力感应阀芯2，阀体主体110的上方设有电源接线端口40，且阀体主体110内形成水流通道，右侧的插脚120内设有逆止阀芯30。插脚120的外周面上并邻近插脚120的自由端处形成有两个沿插脚120的长度方向间隔布置的密封圈槽121，插脚120的中下部形成有螺钉柱5。在安装时，可先将插脚120插接在安装部位，再将螺钉柱5连接在安装部位，结构简单，安装方便。
在使用时，水流从进水口进入逆止高压开关100，水流从逆止高压开关100内部流过时，压力感应阀芯2检测逆止高压开关100内部的水压，当水压达到压力感应阀芯2的感应压力范围时，压力感应阀芯2输出感应信号，并通过电源接线端口40将上述感应信号输出，以使整机执行相应的动作。
根据本发明第一方面实施例的逆止高压开关100，通过将压力感应阀芯2和逆止阀芯30设在阀体1的内部，将单向阀与高压开关集成为一体，由此，减小了元件的占用空间，进而减小了整机的体积。此外，还减少了元件之间的接头数量，降低了漏水的风险，提高了逆止高压开关100的可靠性及安全性且结构简单、安装方便。
根据本发明第二方面实施例的净水器，包括根据本发明上述第一方面实施例的逆止高压开关100。由于上述的逆止高压开关100具有占用空间小、安全性高的有益效果，因此通过设置该逆止高压开关100的净水器，可减小净水器的整体体积，提高净水器的质量。
根据本发明第二方面实施例的净水器(图中未示出)，包括：进水阀、过滤组件以及逆止高压开关。所述过滤组件与所述进水阀相连，逆止高压开关为上述的逆止高压开关100，逆止高压开关100的进水口12与所述过滤组件相连，且逆止高压开关100与所述进水阀相连。由此，通过在所述净水器上设置上述第一方面实施例的逆止高压开关100，使得所述净水器可实现水流单向，且能感应水路压力，实现压力控制的目的。另外，还使得所述净水器的结构更加紧凑，节省占用空间。
本发明提出一种逆止高压开关100，主要通过将所述逆止阀芯(例如单向阀)和高压 开关3进行结构整合，实现逆止高压开关100功能设计，从而实现零部件功能整合及精简。
下面结合图1至图2详细描述根据本发明实施例的逆止高压开关100的工作过程。
具体而言，进水口12与出水口13处均通过密封圈进行水路密封，使得连接不漏水。且通过多个螺栓4实现阀体1与高压开关3的连接固定。
水流从进水口12进入阀体1的阀腔11内，经过所述逆止阀芯，并从出水口13流出。因为所述逆止阀芯可使水路单向流动，因此，水流只能单向流过阀腔11。又因为在水流流过所述逆止阀芯时，通过高压开关3实现水压感应，即当水压到达某个设定值时，通过高压开关3的导向输出信号，用于整机控制。至此完成根据本发明实施例的逆止高压开关100的工作过程。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
