本实施例的马桶，通过进水阀40直接连接日常自来水管，日常用水通过进水阀40进入副水箱20内，当副水箱20内的水达到额度水位线后了，超过额度水位线的水通过溢流孔流入水箱体110内。当马桶实行冲洗时，按下排水阀30，水箱体110内的水由第一冲水道130的进水口独立进入第一冲水道130内，由其喷射口132独立冲水，同时副水箱20抽自来水进入其箱内，产生的压差使副水箱20分配的水量通过第二冲水道150的入水口152，进入第二冲水道150内，通过第二冲水道150的冲洗口154，将自来水里保存的水压势能，转化为对坐便体120的洗净面122的冲洗动能，从而实现通过副水箱20冲洗马桶的洗净面122，完成洗净面122的冲洗。而且通过在副水箱20上设置溢流孔，使副水箱20与进水阀40连通，在控制排水阀30排放水箱体110内的水时，同时使副水箱20内的水被排出，只需通过一个排水阀30即可对两个独立的水道进行冲水，结构设计巧妙。
该马桶的第一冲水道130与第二冲水道150独立分开，两条冲水水道独立的水量分配装置。冲水开始时，冲水水量同时分成两部分：一部分水量分配给副水箱20，冲洗马桶的洗净面122；另一部分水量分配给水箱体110，经排水阀30及喷射口132喷出，与洗净面122流下的水汇合冲洗排污通道140，从而完成整个马桶排污冲洗。实现了冲水水量的按需分配，聚焦冲水水量，聚焦水量的冲水动能，达到冲洗强劲，达到超节水，解决马桶出水无力和排污难的痛点。
与传统的马桶冲洗技术相比，该马桶采用独立增压、冲水水量分开的冲洗原理及结构，聚焦冲水水量和冲水动能，虹吸的力量更强，轻松排污。传统马桶喷射主冲水道和洗净面共用水道，通过水件控制，水件排水阀排出的水量同时对马桶的“洗净面”和“管道”进行冲洗，存在如下限制：1、冲水水量在冲洗马桶洗净面和冲洗管道时，冲水水量不能合理分配，造成马桶排污冲洗困难；2、通过水件排水阀排出的水量同时对马桶“洗净面”和“管道”进行冲洗，冲洗压力分流，造成冲洗动能的减弱或是弱化。另外，因传统马桶结构的不合理，当用户冲洗马桶时，便腔内的脏水易回流或是溢流至分水孔，不易排污。而本实施例马桶采用独立冲水结构，可解决便腔内的脏水倒流至分水孔的问题，可有效的 将的脏水及粪便直接排出排污口；且在冲洗周期内，将污秽物排到排污通道140，易清洁洗净面122，去除沉积或粘附到洗净表面的固体或液体废物，再补水封水进行置换清水，从而使马桶内可保持相对洁净。
进一步地，喷射口132的用水量大于冲洗口154的用水量，本实施例中所述喷射口132的冲水量与所述冲洗口154的冲水量的比例为8:2至9:1。经研究发现，该范围内的水量分配，实现冲水水量的按需分配，聚焦冲水水量，达到冲洗强劲，达到超节水的目的。马桶陶瓷体内有第二冲水道150，该第二冲水道150一端连接副水箱20，另一端连接到洗净面122的冲水槽160，通过进水阀40连接的自来水产生的水压，直接对马桶的洗净面122进行洗刷，使得分配的10％～20％的具有自来水水压的水量有效洗刷洗净面122，进行清洗的自来水水压不仅成功解决了下沉式水箱、低水箱马桶洗刷困难及压力分散冲洗不干净的难题，还保证了80％～90％的主冲水能够聚焦冲洗排污管道，从而快速产生虹吸，达到排污冲洗的目的。
如图2所示，进一步地，第二冲水道150包括位于水箱体110内的水箱段156及位于坐便体120内的坐便段158，所述水箱段156与坐便段158连通，且所述第二冲水道150与所述桶主体10为一体成型结构。即第二冲水道150直接设置在桶主体10上，与陶瓷的桶主体10为一体式结构。图1中所述第二冲水道150的入水口152靠近所述副水箱20设置，减少副水箱20与入水口152之间的连通管路长度，避免能量损失，当然，根据需求，也可开设在水箱体110内的其他适当位置，不限于图2所示位置。图2中第二冲水道150的冲洗口154与冲洗槽连通，冲洗口154设置在靠近右侧的位置，即靠近副水箱20所在侧的位置，减少第二冲水道150的布设长度，避免能量损失，当然，根据需求，也可开设在水箱体110内的其他适当位置，不限于图2所示位置。
进一步地，所述第二冲水道150的内径为10mm至22mm。第二冲水道150为洗净面122的冲刷专用水道，经研究及反复的测试验证，将第二冲水道150的管径设置在该范围内，可保证在副水箱20排水时，能产生更大的冲水动能，保证马桶洗净面122快速冲洗及冲洗力度更加强劲。
如图1、2所示，进一步地，所述第二冲水道150的入水口152与所述副水 箱20的顶端通过管路50连通，且所述第二冲水道150的入水口152高度高于所述第二冲水道150的冲洗口154的高度。日常用水通过进水阀40进入副水箱20，形成自来水水压势能，如图2所示，第二冲水道150与副水箱20的连接结构利用大气压压差原理或类似虹吸式结构，不仅冲洗洗净面122的冲力大，而且能节约所需冲刷水量。
可选地，所述副水箱20上设有至少两个溢流孔(图中未示出)，其中两个溢流孔在副水箱20高度方向间隔设置。溢流孔的设置高度与个数根据两个水道的水量分配需求设置。可设置1、2或多个溢流孔，在其中一个实施例中，所述副水箱20上设有两个溢流孔，两个溢流孔在副水箱20高度方向间隔设置，不仅能使副水箱20内的水能快速进入到水箱体110内，且在冲洗过程中，当水箱体110内的水冲出去时，能快速形成水落差，使副水箱20内补充新水，形式水压差，触发第二冲水道150排水，冲刷马桶的洗净面122。
在其中一个实施例中，所述冲水槽160为环状的开口槽，且冲水槽160与第二冲水道150的冲洗口154连通的一端为高端，冲洗槽的高度由高端沿第二冲水道150的冲水方向逐渐降低，以形成漩涡式水流。当第二冲水道150的水由冲洗口154进入该结构的冲水槽160时，能形成漩涡式水流，直接对马桶的洗净面122进行漩冲洗刷，冲刷力度更大，效果更好。
在另一个实施例中，冲水槽160为环状的通道，且通道靠近桶主体10内侧的壁面上开设有多个过水孔。即当第二冲水道150的水由冲洗口154进入该结构的冲水槽160时，水从各过水孔流出，对洗刷面进行清洗，该结构的冲水槽160能避免污秽物进入冲水槽160。
如图2所示，进一步地，所述第一冲水道130上设有收紧段134，所述收紧段134的口径小于其上游段的口径。即当马桶实行冲洗时，水箱体110内与日常自来水连通的水压势能，按下排水阀30，转化为冲水动能，通过喷射口132喷出对排污通道140进行清洗，此第一冲水道130进行结构优化，在水冲出过程中设收紧段134，让通过此水道的冲水动能更大，排水落差更大，排水更流畅。
如图1、2所示，进一步地，所述排污通道140为虹吸式结构。即该马桶的结构可适用在虹吸式马桶上，具有节水效果好、冲洗效果好、不耗能、噪音小 等优点。
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。
