技术领域
本发明涉及水路切换控制技术领域，尤其涉及一种分配阀及马桶冲刷系统和马桶。
背景技术
常见的分配阀是采用马达驱动分配转盘，通过分配转盘上的分配孔与阀体内部流道的选择性配合，从而实现转动分配转盘实现水路切换的功能。由于切换部件分配转盘通常为转动设置，导致动力源局限性比较大，通常只能选择马达；马达作为动力源输入通常需要与减速齿轮组协同作用，长时间使用可能会出现齿轮配合间隙变大导致分配转盘转动效果下降的缺陷，结构较为复杂。本发明提出一种新型分配阀，其切换部件设置为滑动式，使驱动机构的选择更加多样化。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种分配阀及马桶冲刷系统和马桶。
为实现上述目的，本发明提供了如下技术方案：

进一步的，所述泄压孔处于开启状态时，所述进水口与第一出水口连通；所述泄压孔处于关闭状态时，所述进水口与第二出水口连通。
进一步的，所述滑动杆一端设有支撑盘，以支撑所述止水膜片，该支撑盘与所述细水孔对应的位置设有一细水柱，该细水柱穿过所述细水孔。
进一步的，所述滑动杆另一端穿过所述第二开口，所述密封垫位于第二开口外侧，所述滑动杆另一端螺纹连接有紧固螺钉，该紧固螺钉限制所述密封垫脱离所述滑动杆。
进一步的，所述滑动杆上还套装有密封圈，该密封圈在所述滑动杆穿出所述第二腔体时与第二腔体密封配合。
进一步的，所述密封圈的径向截面呈V字形。

进一步的，所述机械开关包括固定支架、压杆、传动杆和复位弹簧，所述压杆与传动杆一端铰接，用于控制所述传动杆移动；所述固定支架具有内腔，所述传动杆的另一端置于所述内腔且通过连接块连接用于启闭所述泄压孔的堵头，所述复位弹簧套装在所述连接块外，用于复位所述堵头。

本发明的有益效果是：
本发明提出的一种分配阀，将现有技术中常为转动设置的切换部件优化为滑动设置，无需安装减速齿轮组，结构简单；同时，相对一个控制阀控制一个水路的常见结构方式，本发明提出一进两出但仅需一个驱动机构的新型分配阀，通过切换部件的滑动设置实现进水口分别与第一出水口和第二出水口间的连通，实现水路切换。
本发明提出的一种分配阀，采用先导阀结构，利用止水膜片两侧的压差从而带动滑动杆上下移动，进而实现进水口分别与第一出水口和第二出水口的连通，结构可靠性好，操作更省力；另外在滑动杆外套设有密封圈，使得滑动杆上下滑动实现水路切换的同时避免第二腔体与第二出水口的连通。

具体实施方式
下面结合图1-10对本发明进行详细说明。
一种分配阀，包括阀体10，以及设置于该阀体10的切换部件60和用于驱使切换部件60动作的驱动机构，阀体10设有进水口101、第一出水口102和第二出水口103，进水口101与第一出水102口或第二出水口103垂直设置；切换部件60滑动连接于阀体10中，并通过滑动切换部件60控制第一出水口102和第二出水口103与进水口101切换连通。
本实施例中，切换部件60包括止水膜片601、滑动杆602和密封垫603，止水膜片601套装于滑动杆602一端，密封垫603套装于滑动杆602另一端，止水膜片601在阀体10内分隔出进水腔和背压腔30，背压腔30设有泄压孔40，该泄压孔40由驱动机构控制开启与否；进水腔包括第一腔体201和第二腔体202，第一腔体201连通进水口101，第二腔体202连通第一出水口102，止水膜片601上设有连通第一腔体201和背压腔30的细水孔；第二腔体202设有用于连通第一腔体201的第一开口501，该第一开口501由止水膜片601控制启闭；滑动杆602滑动穿设于第二腔体202，且其局部密封穿出第二腔体202，并进入第一腔体201内，第一腔体201设有用于连通第二出水口103的第二开口502，该第二开口502 由密封垫603控制启闭；背压腔30内设置供切换部件60复位的弹性件80。止水膜片601靠近背压腔30一侧的表面积大于靠近第一腔体201一侧的表面积，使得在泄压孔40关闭的情况下，背压腔30内的受压面大于第一腔体201的受压面，利用止水膜片601两侧的压差从而带动滑动杆602移动。
本实施例中，滑动杆602一端设有支撑盘6021，以支撑止水膜片601，该支撑盘6021与细水孔对应的位置设有一细水柱6022，该细水柱6022穿过细水孔，可以防止细水孔变形而影响水流通过。
本实施例中，泄压孔40处于开启状态时，进水口101与第一出水口102连通；泄压孔40处于关闭状态时，进水口101与第二出水口103连通。原因在于，当泄压孔40开启时，背压腔30内的水压迅速下降，由于细水柱6022的孔径较小，背压腔30的进水比较慢，进水腔进水快，使得进水腔内的水压大于背压腔30内的水压，从而顶开止水膜片601，打开第一开口501，关闭第二开口502，使得外部水流由进水口101进入后依次流入第一腔体201和第二腔体202，最后由第一出水口102流出；而当泄压孔40关闭时，在弹性件80的作用下支撑盘6021和止水膜片601向下移动，关闭第一开口501，打开第二开口502，使得外部水流由进水口101进入后流入第一腔体201并由第二出水口103流出。
本实施例中，滑动杆602另一端穿过第二开口502，密封垫603位于第二开口502外侧，滑动杆602另一端螺纹连接有紧固螺钉605，该紧固螺钉605限制密封垫603脱离滑动杆602。
本实施例中，滑动杆602上还套装有密封圈604，该密封圈604在滑动杆602穿出第二腔体202时与第二腔体202密封配合，密封圈604可跟随滑动杆602同向移动，用于密封和阻隔第二腔体202与第二出水口103连通；因该密封圈604存在活动/移动状态，为了保证在移动过程中较低的密封阻力，密封圈604的径向截面呈V字形。
进一步的，第一腔体201位于第二腔体202外围，进水口101和第一出水口102位于第一腔体201侧面，第二出水口103与第二开口502相对。
驱动机构为电磁阀头70。如图9A、图9B所示，电磁阀头70包括固定支架701、线圈组件702、动铁芯703和复位弹簧704，线圈组件702通过固定支架701固定于阀体10外，动铁芯703活动设置于线圈组件702中，且动铁芯703的一端 设置用于启闭泄压孔40的堵头-I 7031，复位弹簧-I 704套装在动铁芯703外，用于复位动铁芯703。
在另一实施例中，驱动机构为机械开关90。如图10A、图10B所示，机械开关90包括固定支架-II 901、压杆902、传动杆903和复位弹簧-II 904，压杆902与传动杆903一端铰接，用于控制传动杆903移动；固定支架-II 901具有内腔，传动杆903的另一端置于内腔且通过连接块905连接用于启闭泄压孔40的堵头-II 906，复位弹簧-II 904套装在连接块905外，用于复位堵头-II 906。
当驱动机构采用电磁阀头70时，其工作原理如下：
电磁阀头70未通电时，在复位弹簧-I 704的作用下，堵头-I 7031堵住泄压孔40，在弹性件80的作用下，止水膜片601和滑动杆602向下移动，关闭第一开口501，密封垫603打开第二开口502，使得外部水流由进水口101进入后流入第一腔体201并由第二出水口103流出；电磁阀头70通电时，线圈组件702吸附动铁芯703向上移动，使得堵头-I 7031向上移动，从而打开泄压孔40，使得进水腔压力大于背压腔30，止水膜片601和滑动杆602向上移动，止水膜片601打开第一开口501，密封垫603关闭第二开口502，使得外部水流由进水口101进入后依次流入第一腔体201和第二腔体202，最后由第一出水口102流出。
当驱动机构采用机械开关90时，其工作原理如下：
默认状态下，压杆902未受外力按压，在复位弹簧-II 904作用下，堵头-II 906堵住泄压孔40，在弹性件80的作用下，止水膜片601和滑动杆602向下移动，关闭第一开口501，密封垫603打开第二开口502，使得外部水流由进水口101进入后流入第一腔体201并由第二出水口103流出；当压杆902受外力按压时，传动杆903抬起，从而令堵头-II 906打开泄压孔40，使得进水腔压力大于背压腔30，止水膜片601和滑动杆602向上移动，止水膜片601打开第一开口501，密封垫603关闭第二开口502，使得外部水流由进水口101进入后依次流入第一腔体201和第二腔体202，最后由第一出水口102流出。
本发明还提供了一种马桶冲刷系统，包括泵压水进水管、喷射管道、刷圈管道，以及上述分配阀，所述进水口与所述泵压水进水管连接，所述第一出水口与所述喷射管道连接，所述第二出水口与所述刷圈管道连接。泵压水进水管可连接水泵的出水端，水泵的进水端则可连通马桶的水箱。当水泵启动时，水泵将水箱 中的水抽出，并经分配阀实现喷射出水和/或刷圈出水。
本发明另提供一种马桶，包括便池，还包括如上所述的马桶冲刷系统，所述刷圈管道连通所述便池顶部设置的刷圈孔或刷圈喷头，所述喷射管道连通所述便池底部设置的喷射口或喷射喷头。
上述实施例只为说明本发明的技术构思及特点，其目的在于让本领域技术人员能够了解本发明内容并加以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
