本申请要求于2018年08月24日提交中国专利局，申请号为2018213824268，发明名称为“冲水装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及马桶技术领域，尤其涉及一种用于马桶的冲水装置。
传统陶瓷马桶中的冲水装置，冲洗水和洗刷水是共用一个马桶本身的陶瓷水箱，但是这样的冲水系统容易导致水箱的陶瓷马桶洗刷水，冲洗水不足，冲洗效果不好，而高水箱的陶瓷马桶体积大，占用空间，并且用水量较大，不符合当今提倡的环保节能概念，加上陶瓷陶瓷水箱的制作工艺比较复杂，成品率低。
通常的无水箱马桶是利用自来水冲洗和洗刷，对自来水的水压要求比较高，面临着难题是，必须控制一定水压和流量，同时做到洗刷和冲洗干净。
发明内容
根据本申请的各种实施例，提供一种冲水装置。
一种冲水装置，包括箱体、满水液位开关、缺水液位开关、单向阀板、压板机构、封盖、进水机构、第一排水机构和第二排水机构；所述箱体内部设有隔板，所述隔板将所述箱体的内腔分隔成洗刷腔和冲洗腔；所述隔板具有一直板状的倾斜部，所述倾斜部自所述洗刷腔朝向所述冲洗腔逐渐变低，所述倾斜部上设有穿孔；所述封盖盖设于所述箱体的顶部；所述进水机构和 所述第一排水机构均连通所述洗刷腔；所述第二排水机构连通所述冲洗腔；所述满水液位开关和缺水液位开关的探头均位于所述冲洗腔内；所述单向阀板对应所述穿孔设置于所述冲洗腔内；所述单向阀板靠近所述封盖的一端铰接所述倾斜部，所述单向阀板靠近所述隔板的一侧设有环绕所述穿孔的密封圈；所述压板机构包括安装于所述封盖上的驱动组件以及对应所述单向阀板设于所述洗刷腔内的压板，所述压板平行于所述倾斜部，并连接所述驱动组件。
上述的冲水装置，通过设置洗刷腔和冲洗腔，当要冲洗马桶时，洗刷腔里的水先对马桶的侧壁进行洗刷，洗刷腔内的水位下降，然后通过排出冲洗腔内的水冲洗马桶，但是由于单向阀板的阻隔作用，冲洗腔内的水不会流入洗刷腔内，从而保证冲洗腔内有足够的水量冲洗马桶，冲洗效果好，且体积小；在进水阶段，当洗刷腔和冲洗腔内的水都达到指定液位时，驱动组件驱动压板压于单向阀板上，以使密封圈紧压于隔板的倾斜部上，以使冲洗腔内的水不易从单向阀板和隔板之间反流入至洗刷腔内，进一步保证了冲洗腔内有足够的水量用来冲洗马桶。

请参阅图1和图2，为本发明一实施例的一种冲水装置，该冲水装置用于冲洗马桶。冲水装置包括箱体10、封盖20、进水机构30、第一排水机构40、第二排水机构50、满水液位开关61、缺水液位开关62、单向阀板70以及压板机构80。
箱体10大致为矩形机构，当然在其他实施例中，也可以为圆形或者其他形状。箱体10内部中空，用于存储干净水，以便于冲洗马桶和清洗马桶侧壁；箱体10内部设有隔板11，隔板11将箱体10的内腔分隔成洗刷腔16和冲洗腔17，洗刷腔16内的水用于冲洗马桶的侧壁，冲洗腔17内的水用于冲洗马桶；隔板11可以为规则的板状结构，也可以为不规则的板状结构。隔板11具有一平板状的倾斜部12，倾斜部12自洗刷腔16朝向冲洗腔17逐渐变低，倾斜部12上设有穿孔15，用于使洗刷腔16内的水能进入冲洗腔17内。封盖2020盖设于箱体10的顶部，用于将避免外界的灰尘进入至箱体10内。
进水装置30进水机构30设于封盖20上，并连通洗刷腔16，用于连接外部的自来水管，以给洗刷腔16供应干净水。进水机构30用于连接外部的控制装置，通过外部的控制装置控制是否给箱体10供应干净水。具体的，进水机构30包括设于封盖20上的进水管31以及设于进水管31上的进水控制阀32。
在其中一实施例中，封盖20上对应进水管31的出水口安装有网状的过滤筒，过滤筒位于箱体10内，用于对进水管31供应的水进行过滤，以将进水管31供应的水中的粒径较大的杂质去除掉，避免箱体10的内壁上积聚污垢。
第一排水机构40和第二排水机构50均设于箱体10的底部；第一排水机构40和第二排水机构50分别连通洗刷腔16和冲洗腔17。第一排水机构40用于将洗刷腔16内的水排出来刷洗马桶的侧壁；第二排水机构50用于将冲洗腔17内的水排出来冲洗马桶。第一排水机构40和第二排水机构50均用于连通外部的控制装置，以使外部的控制装置控制第一排水机构40和第二排水机构50的通断。具体的，第一排水机构40包括第一排水管41和设于第一出水管41上的第一排水控制阀42；第二排水机构50包括第二出水管51和设于第二出水管51上的第二排水控制阀52。
满水液位开关61和缺水液位开关62设于箱体10上，满水液位开关61的探头和缺水液位开关62的探头均位于冲洗腔17内。满水位液位开关位于低水位液位开关的上方。满水液位开关61和缺水液位开关62均用于连接外部的控制装置。满水液位开关61用于检测冲洗腔17内的水是否达到指定液位，若达到，满水位液位开关61发送信息给控制装置，控制装置根据该信息控制进水控制阀32关闭进水管31的通道，停止进水管31供水。缺水液位开关62用于检测冲洗腔17内的水是否用完，若检测到冲洗腔17内缺水，发送信息给控制装置，控制装置根据该信息控制进水控制阀32打开进水管31的通道，以使进水管31再次供水。
单向阀板70对应穿孔15设置于冲洗腔17内；单向阀板70靠近封盖20的一端铰接倾斜部12，单向阀板70靠近隔板11的一侧设有环绕穿孔15的密封圈71。在本实施例中，密封圈71粘贴于单向阀板70上。在其他实施例中，也可以是密封圈71嵌设于单向阀板70设置的密封槽内。在第一排水控制阀42没有开启的情形下，当洗刷腔16内的水达到穿孔15所在的高度位置时，冲洗腔17内的水会将单向阀板70推离穿孔15，使得穿孔15打开，水 通过打开的穿孔15进入冲洗腔17内；当洗刷腔16内的水和冲洗腔17内的水均达到指定高度时，单向阀板70整个浸泡于水中，单向阀板70因为其两侧受到的水力大致相等，故会在其自身重力作用下压于倾斜部12上，阻止洗刷腔16内的水继续进入冲洗腔17内，同时满水液位开关61检测到信号，控制进水控制阀32关闭，使进水管31停止往洗刷腔16内供水。
压板机构80包括安装于封盖20上的驱动组件81以及对应单向阀板70设于洗刷腔16内的压板84，压板84平行于倾斜部12；驱动组件81连接倾斜部12，用于在冲洗腔17内的水达到指定液位后，通过压于单向阀板70上以将密封圈71紧压于倾斜部12上，从而使冲洗腔17内的水不会在洗刷腔16内的水用完后轻易进入洗刷腔16内，保证冲洗腔17内有足够地水量用来冲洗马桶。
具体的，驱动组件81包括安装于封盖20上的升降气缸82、连接升降气缸82的输出轴和压板84的连接杆83。
连接杆83螺纹可拆卸连接压板84，以便于压板84地拆装。具体的，如图2所示，压板84靠近升降气缸82的侧面上延伸形成有安装筒85，连接杆83插设于安装筒85内且与安装筒85螺纹连接。压板84和连接杆83这样的连接方式，连接杆83的伸出安装筒85的长度能够根据单向阀板70的高度位置进行调节，以使升降气缸82能够驱动压板84压于与倾斜部12相贴的单向阀板70上。
如图2所示，倾斜部12上设有与单向阀板70枢接连接凸起13。为了使压板84能通过单向阀板70将密封圈71更好地压于倾斜部12上，单向阀板70通过转轴72枢接连接凸起13，连接凸起13对应转轴72设有枢接滑孔14，枢接滑孔14沿垂直于倾斜部12的方向延伸，转轴72滑设于枢接滑孔14内。枢接滑孔14的设置能使得压板84压于单向阀板70时，单向阀板70能沿垂直于倾斜部12的方向移动，以使整个密封圈71受力均匀地压于倾斜部12上，能实现单向阀板70和倾斜部12之间良好的密封性。
在其中一实施例中，隔板11面向洗刷腔16的一侧布满有若干横纵交错 的加强筋，用于加强隔板11的强度，使得隔板11的倾斜部12不易在压板机构80的作用力下发生变形。
上述的冲水装置的工作原理为：
当需往箱体10内填满水时，开启进水控制阀32，进水管31往洗刷腔16内供应水，当洗刷腔16内的水达到穿孔15所在的高度位置时，洗刷腔16内的水推动单向阀板70远离穿孔15，洗刷腔16内的水通过打开的穿孔15流入到冲洗腔17内，当冲洗腔17内的水达到满水液位开关61所在的高度位置时，满水液位开关61检测到水信号，并将信号发送给控制装置，控制装置控制进水控制阀32关闭，进水管31停止往洗刷腔16内供水。同时单向阀板70也在冲洗腔17内的水的作用力下以及其自身重力的作用下压于隔板11的倾斜部12上，以将穿孔15封住；在单向阀板70靠近隔板11运动封住穿孔15的过程中，控制装置还会控制升降气缸82驱动压板84向下运动压于单向阀板70上，以使单向阀板70的密封圈71紧压于隔板11的倾斜部12上，实现单向阀板70和倾斜部12之间的紧密密封。
当需冲洗马桶时，先开启第一排水控制阀42，洗刷腔16内的水通过第一出水管41排出，用以先对马桶的侧壁进行洗刷，洗刷腔16内的水面下降，但是由于单向阀板70和压板机构80的阻隔作用，冲洗腔17内的水不会流入洗刷腔16内，当洗刷腔16内的水排完后，关闭第一排水控制阀42，打开第二排水控制阀52，冲洗腔17内的水通过第二出水管51排出，用于冲洗马桶，给冲洗马桶保证了足够的水，冲洗效果好，而且体积小。当缺水液位开关62没有检测到水时，缺水液位开关62发送信息给控制装置，控制装置控制第二排水控制阀52关闭，控制升降气缸82驱动压板84远离单向阀板70，直至压板84返回原来位置，同时控制进水控制阀32打开，以使进水管31再次为箱体10内供应水。由于第二排水控制阀52有滞性，洗刷腔16内的水达到穿孔15所在位置的时间可以给第二排水控制阀52提供足够多的时间关闭。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这 些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
