- the common double-speed jet siphon toilet the water guide pipe connects the jet pipe and the washing ring pipe
- the water in the water chamber flows from the drain port of a double-speed drain valve into the water guide pipe, and passes through the jet pipe all the way. It is sprayed from the jetting port at the bottom of the urine and stool cavity, and is sprayed from the washing ring flushing hole in the upper part of the urine and stool cavity all the way through the washing ring pipe.
- the feces to be flushed are easily blocked.
- the toilet is usually designed so that most of the water is sprayed from the bottom jet port to push the dirt and prevent clogging, so most of the water is distributed to the jet port.
- the flushed urine is not blocked, but it is easy to splash the urine and feces.
- more water should be allocated to the flushing hole of the washing ring for flushing the urine and feces.
- the cavity is splashed, but this cannot be achieved because it has been known from the above analysis that the distribution ratio of water between the jet port and the wash ring flushing hole is the same when the existing toilet is flushed in high gear and low gear.
- the above problems will be more obvious on the water-saving toilets. Since the water consumption of the water-saving toilets is very small, the large-scale flushing has to use a larger proportion of water for the injection port to prevent blocking, and the small-scale flushing water consumption is extremely high. It is small, and it has to use a larger proportion of water for spraying like the high-speed flushing, which results in that the water sprayed from the flushing hole of the washing ring is often so little that it can only wet the urination and defecation cavity, and some even even the urination and defecation cavity. It is impossible to wash them all, let alone rinse the splashes on the urinal cavity.

详述
下文中将结合附图对本申请的实施例进行说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
分析研究发现：普通双档喷射虹吸式坐便器，导水管道将喷射管道和洗圈管道连通起来，盛水腔内的水从一个双档排水阀的排水口流入导水管道，一路经过喷射管道从尿便腔底部喷射口喷出，一路经过洗圈管道从尿便腔上部的洗圈冲洗孔喷出。上述结构一旦成型，自导水管道排出的水在喷射口(喷射管道)和洗圈冲洗孔(洗圈管道)之间的分配比例即被固定下来，不论是大档冲刷(即：大便冲水)还是小档冲刷(即：小便冲水)，水在喷射口和洗圈冲洗孔之间的分配比例基本是一样的。
对于大档冲刷而言，其所冲洗的大便容易堵塞，坐便器通常都设计成大部分水从底部喷射口喷出，推动污物，防止堵塞，故绝大部分水分配给喷射口。而对于小档冲刷而言，其所冲洗的小便并没有堵塞的问题，反而是小便容易将尿便腔各处溅污，此时应该分配更多的水给洗圈冲洗孔用于冲洗尿便 腔溅污，但这是无法实现的，因为从上述分析已经知道，现有坐便器大档冲刷和小档冲刷时，水在喷射口和洗圈冲洗孔之间的分配比例是一样的。而且上述问题在节水坐便器上会更加明显，由于节水坐便器用水量很少，大档冲刷不得不将更多比例的水用于喷射口喷射防堵，小档冲刷用水量本来就极小，又不得不和大档冲刷一样将更多比例的水用于喷射，这就造成洗圈冲洗孔喷出的水常常少到仅能将尿便腔润湿，有些甚至连尿便腔都无法全部洗到，更谈不上将尿便腔上的溅污冲洗干净了。
因此，亟需提供一种坐便器，要求在不增加出水量的要求下，能够满足在大便冲水时以一种分配方式合理分配喷射口出水和洗圈冲洗孔出水，在小便冲水时以另一种分配方式合理分配喷射口出水和洗圈冲洗孔出水，确保大便冲水和小便冲水时均能够将尿便腔冲洗干净。
本申请一实施例提供了一种排水装置，可应用于坐便器，可在不增加冲水量的基础上，满足在大便冲水时以一种分配方式合理分配喷射口出水和洗圈冲洗孔出水，在小便冲水时以另一种分配方式合理分配喷射口出水和洗圈冲洗孔出水的要求，确保大便冲水和小便冲水时均能够将尿便腔冲洗干净。
本文提供了一种坐便器，如图1至图5所示，可包括马桶主体100、进水阀200和排水装置300。

本文中，“驱动键与驱动杆的配合”、“驱动杆与驱动组件的配合”、“驱动键与驱动组件的配合”中的“配合”指传动配合，即驱动键能带动驱动杆动作、驱动杆能带动驱动组件动作、驱动键能带动驱动组件动作。
该坐便器的动作方式及效果：
如图4所示，进行大便冲水时，按压第一驱动键311，第一驱动键311推动驱动杆330和第一挡杆342摆动，第二挡杆352不摆动，第二杆体332通过上拉第一连接绳341和第二连接绳351打开第一阀盖362和第二阀盖372，第一摆杆343和第二摆杆353摆动。由于第一挡杆342的下端向上摆动，避让开了第一摆杆343上端的摆动行程，故第一摆杆343越过第一挡杆342的下端摆动至最大位置，第一阀盖362开盖至最大开盖角度。在第一阀盖362开盖至最大开盖角度的过程中，第一摆杆343一方面随第一阀盖362一起摆动，另一方面还可在配重结构3431的作用下相对第一阀盖362摆动，使第一摆杆343由限位凸筋344与第一阀盖362相抵的状态变化至限位凸筋344’与第一阀盖362相抵的状态。
由于第二挡杆352未摆动，第二挡杆352的下端干涉第二摆杆353上端的摆动行程，故第二摆杆353的上端摆动至抵在第二挡杆352下端的阻挡部3521而无法摆动至最大位置，第二阀盖372无法开盖至最大开盖角度，第二摆杆353处于限位凸筋354与第二阀盖372相抵的状态。此时，盛水腔120内的水同时从第一阀筒361和第二阀筒371排出，一路经过洗圈管道140从洗圈冲洗孔112喷出清洗尿便腔110的侧面，另一路经过喷射管道130从喷射口111喷出，推动尿便腔110底部的污物排出，并使水快速填充虹吸管道150。第一驱动键311松开后，在配重结构3531和3431的作用下(配重结构3531产生使第二阀盖372关闭的力矩，配重结构3431产生使第一阀盖362打开的力矩)，第二阀盖372优先回落关闭第二阀筒371，第一阀盖362滞 后回落关闭第一阀筒361。第二排水阀370关闭后，第一排水阀360继续排水，喷射口111持续强劲喷射防堵。
盛水腔120内的水位持续下降，第一阀盖362部分露出水面，导致第一阀盖362受到的浮力下降，最终第一阀盖362快速下落关闭第一阀筒361，喷射口111停止出水(参见图6和图7所示的第二阀盖372的摆动过程，类似第二阀盖372的摆动过程，第一阀盖362摆动下落过程中，第一阀盖362的开盖角度逐渐减小，而且第一摆杆343保持在最大摆动角度(即限位凸筋344’与第一阀盖362相抵的状态)时的高度较第一摆杆343保持在初始位置(即限位凸筋344与第一阀盖362相抵的状态)时的高度更低，因此第一摆杆343回摆过程中，第一摆杆343的上端低于第一挡杆342下端的阻挡部3421，不会受到第一挡杆342下端的阻挡，第一摆杆343可以顺利回摆，可实现第一阀盖362盖装在第一阀筒361上)。即：大比例的水自第一排水阀360经喷射口111排出，小比例的水自第二排水阀370经洗圈冲洗孔112排出，尿便腔110不会堵塞，而且尿便腔110内侧面也能够被冲洗干净。
如图5所示，进行小便冲水时，按压第二驱动键312，第二驱动键312推动驱动杆330和第二挡杆352摆动，第一挡杆342不摆动，驱动杆330通过上拉第一连接绳341和第二连接绳351打开第一阀盖362和第二阀盖372，第一摆杆343和第二摆杆353摆动。由于第二挡杆352的下端向上摆动，避让开了第二摆杆353上端的摆动行程，故第二摆杆353越过第二挡杆352的下端摆动至最大位置，第二阀盖372开盖至最大开盖角度。在第二阀盖372开盖至最大开盖角度的过程中，第二摆杆353一方面随第二阀盖372一起摆动，另一方面还可在配重结构3531的作用下相对第二阀盖372摆动，使第二摆杆353由限位凸筋354与第二阀盖372相抵的状态变化至限位凸筋354’与第二阀盖372相抵的状态。
由于第一挡杆342未摆动，第一挡杆342的下端干涉第一摆杆343上端的摆动行程，故第一摆杆343的上端摆动至抵在第一挡杆342下端的阻挡部3421而无法摆动至最大位置，第一阀盖362无法开盖至最大开盖角度，第一摆杆343处于限位凸筋344与第一阀盖362相抵的状态。此时，盛水腔120内的水同时从第一阀筒361和第二阀筒371排出，一路经过洗圈管道140从 洗圈冲洗孔112喷出清洗尿便腔110的侧面，另一路经过喷射管道130从喷射口111喷出，推动尿便腔110底部的污物排出，并使水快速填充虹吸管道150。第二驱动键312松开后，在配重结构3431和3531的作用下(配重结构3431产生使第一阀盖362关闭的力矩，配重结构3531产生使第二阀盖372打开的力矩)，第一阀盖362优先回落关闭第一阀筒361，第二阀盖372滞后回落关闭第二阀筒371。虹吸管道150逐渐形成虹吸，然后第一阀盖362很快下落，第一排水阀360关闭后，喷射口111停止喷射。第二排水阀370继续排水，洗圈冲洗孔112持续出水冲洗尿便腔110内侧面的溅污，同时在虹吸作用下，尿便腔110底部的水不断被虹吸管道150吸走。
盛水腔120内的水位继续下降，第二阀盖372部分露出水面，第二阀盖372浮力下降，第二阀盖372快速下落关闭第二阀筒371，第二排水阀370关闭，洗圈冲洗孔112逐渐停止出水(参见图6和图7，第二阀盖372摆动下落过程中，第二阀盖372的开盖角度逐渐减小，而且第二摆杆353保持在最大摆动角度(即限位凸筋354’与第二阀盖372相抵的状态)时的高度较第二摆杆353保持在初始位置(即限位凸筋354与第二阀盖372相抵的状态)时的高度更低，因此第二摆杆353回摆过程中，第二摆杆353的上端低于第二挡杆352下端的阻挡部3521，不会受到第二挡杆352下端的阻挡，第二摆杆353可以顺利回摆，可实现第二阀盖372盖装在第二阀筒371上)。即：小比例的水自第一排水阀360经喷射口111排出，大比例的水自第二排水阀370经洗圈冲洗孔112排出，尿便腔110能够更好地被冲洗干净。
本申请实施例提供的排水装置，应用于坐便器，驱动第一驱动键311动作，驱动杆330带动第一驱动组件340和第二驱动组件350分别打开第一排水阀360和第二排水阀370，且在第一驱动组件340和第二驱动组件350的作用下，第一排水阀360滞后于第二排水阀370关闭，使第一排水阀360的排水量增大、第二排水阀370的排水量减小，大比例的水自第一排水阀360经喷射口111排出，小比例的水自第二排水阀370经洗圈冲洗孔112排出，进行大便冲水时尿便腔110不会堵塞，而且尿便腔110内侧面也能够被冲洗干净；驱动第二驱动键312动作，驱动杆330带动第一驱动组件340和第二驱动组件350分别打开第一排水阀360和第二排水阀370，且在第一驱动组 件340和第二驱动组件350的作用下，第二排水阀370滞后于第一排水阀360关闭，使第二排水阀370的排水量增大、第一排水阀360的排水量减小，小比例的水自第一排水阀360经喷射口111排出，大比例的水自第二排水阀370经洗圈冲洗孔112排出，进行小便冲水时尿便腔110能够更好地被冲洗干净，因此，这种坐便器进行小便冲水和大便冲水的冲洗效果均更好。而且，第一排水阀360的进水口低于第二排水阀370的进水口，因此大便冲水的排水量大于小便冲水的排水量，小便冲水更节水。冲刷结束，进水阀200向盛水腔120内进水，盛水腔120内的水位升高到工作状态。第一排水阀360为喷射排水阀，第二排水阀370为洗圈排水阀，喷射管道130的水封存水段内存有水。
本申请实施例提供的坐便器的冲水方法，包括：进行大便冲水时，控制增大喷射排水阀的排水量、减小洗圈排水阀的排水量，实现喷射管道的出水量增大、洗圈管道的出水量减小；进行小便冲水时，控制减小喷射排水阀的排水量、增大洗圈排水阀的排水量，实现喷射管道的出水量减小、洗圈管道的出水量增大。
其中，“控制增大或减小喷射排水阀的排水量”是指控制增大或减小喷射排水阀的排水量占一次冲水过程中的总排水量的比例，“控制增大或减小洗圈排水阀的排水量”是指控制增大或减小洗圈排水阀的排水量占一次冲水过程中的总排水量的比例。
可以是，进行大便冲水时，优先关闭打开的洗圈排水阀、滞后关闭打开的喷射排水阀，使喷射排水阀的打开时长大于洗圈排水阀的打开时长，实现增大喷射排水阀的排水量、减小洗圈排水阀的排水量的目的，其中喷射排水阀和洗圈排水阀可以设置为同时打开；进行小便冲水时，优先关闭打开的喷射排水阀、滞后关闭打开的洗圈排水阀，使喷射排水阀的打开时长小于洗圈排水阀的打开时长实现减小喷射排水阀的排水量、增大洗圈排水阀的排水量的目的，其中喷射排水阀和洗圈排水阀可以设置为同时打开；或者可以是，洗圈排水阀和喷射排水阀采用电控阀，通过控制板进行控制的方式实现上述冲洗方法，以上均可实现本文的目的，其宗旨未脱离本文的设计思想，在此不再赘述，均应属于本文的保护范围内。
在一示例性实施例中，如图4所示，第一排水阀360可用作喷射排水阀，第二排水阀370可用作洗圈排水阀。进行大便冲水时，驱动第一驱动键311动作，驱动杆330带动第一驱动组件340和第二驱动组件350分别打开喷射排水阀和洗圈排水阀，且在第一驱动组件340和第二驱动组件350作用下，喷射排水阀滞后于洗圈排水阀关闭，实现增大喷射排水阀的排水量、减小洗圈排水阀的排水量。
示例地，如图4所示，进行大便冲水时，按压第一驱动键311，第一驱动键311推动驱动杆330和第一挡杆342摆动，驱动杆330通过上拉第一连接绳341和第二连接绳351打开第一阀盖362和第二阀盖372，第一摆杆343和第二摆杆353摆动。第一挡杆342的下端向上摆动，避让开第一摆杆343上端的摆动行程，因此第一摆杆343越过第一挡杆342的下端摆动至最大位置，第一阀盖362开盖至最大开盖角度。第二挡杆352未摆动，第二挡杆352的下端干涉第二摆杆353上端的摆动行程，因此第二摆杆353的上端摆动至抵在第二挡杆352下端的阻挡部3521而无法摆动至最大位置，第二阀盖372无法开盖至最大开盖角度。
此时，盛水腔120内的水同时从第一阀筒361和第二阀筒371排出，一路经过洗圈管道140从洗圈冲洗孔112喷出清洗尿便腔110的侧面，另一路经过喷射管道130从喷射口111喷出，推动尿便腔110底部的污物排出，并使水快速填充虹吸管道150。
第一驱动键311松开后，在配重结构3431和3531的作用下，第二阀盖372优先回落关闭第二阀筒371，第一阀盖362滞后回落关闭第一阀筒361。洗圈排水阀关闭后，喷射排水阀继续排水，喷射口111持续强劲喷射防堵。盛水腔120内的水位持续下降，第一阀盖362部分露出水面，导致第一阀盖362受到的浮力下降，最终第一阀盖362快速下落关闭第一阀筒361，喷射口111停止出水(参见图6和图7所示的第二阀盖372的摆动过程，类似地，第一阀盖362摆动下落过程中，第一阀盖362开盖角度减小，而且第一摆杆343保持在最大摆动角度时高度更低，因此第一摆杆343回摆过程中上端低于第一挡杆342的下端，不会受到第一挡杆342下端的阻挡，第一摆杆343可以顺利回摆，可实现第一阀盖362盖装在第一阀筒361上)。即：大比例 的水自喷射排水阀经喷射口111排出，小比例的水自洗圈排水阀经洗圈冲洗孔112排出，尿便腔110不会堵塞，而且尿便腔110内侧面也能够被冲洗干净。
示例地，如图4所示，第一阀筒361和第二阀筒371的内径可相同，进行大便冲水时，喷射排水阀的排水量大于洗圈排水阀的排水量。
在一示例性实施例中，如图5所示，进行小便冲水时，驱动第二驱动键312动作，驱动杆330带动第一驱动组件340和第二驱动组件350分别打开喷射排水阀和洗圈排水阀，且在第一驱动组件340和第二驱动组件350作用下，洗圈排水阀滞后于喷射排水阀关闭，实现增大洗圈排水阀的排水量、减小喷射排水阀的排水量。
示例地，如图5所示，进行小便冲水时，按压第二驱动键312，第二驱动键312推动驱动杆330和第二挡杆352摆动，驱动杆330通过上拉第一连接绳341和第二连接绳351打开第一阀盖362和第二阀盖372，第一摆杆343和第二摆杆353摆动。第二挡杆352的下端向上摆动，避让开第二摆杆353上端的摆动行程，因此第二摆杆353越过第二挡杆352的下端摆动至最大位置，第二阀盖372开盖至最大开盖角度。第一挡杆342未摆动，第一挡杆342的下端干涉第一摆杆343上端的摆动行程，因此第一摆杆343的上端摆动至抵在第一挡杆342下端的阻挡部3421而无法摆动至最大位置，第一阀盖362无法开盖至最大开盖角度。
此时，如图5所示，盛水腔120内的水同时从第一阀筒361和第二阀筒371排出，一路经过洗圈管道140从洗圈冲洗孔112喷出清洗尿便腔110的侧面，另一路经过喷射管道130从喷射口111喷出，推动尿便腔110底部的污物排出，并使水快速填充虹吸管道150。第二驱动键312松开后，在配重结构3431和3531的作用下，第一阀盖362优先回落关闭第一阀筒361，第二阀盖372滞后回落关闭第二阀筒371。虹吸管道150逐渐形成虹吸，然后第一阀盖362很快下落，喷射排水阀关闭后，喷射口111停止喷射。洗圈排水阀继续排水，洗圈冲洗孔112持续出水冲洗尿便腔110内侧面的溅污，同时在虹吸作用下，尿便腔110底部的水不断被虹吸管道150吸走。盛水腔120内的水位继续下降，第二阀盖372部分露出水面，第二阀盖372浮力下降， 第二阀盖372快速下落关闭第二阀筒371，洗圈排水阀关闭，洗圈冲洗孔112逐渐停止出水。即：小比例的水自喷射排水阀经喷射口111排出，大比例的水自洗圈排水阀经洗圈冲洗孔112排出，尿便腔110能够更好地被冲洗干净。
示例地，如图5所示，第一阀筒361和第二阀筒371的内径可相同，进行小便冲水时，洗圈排水阀的排水量大于喷射排水阀的排水量。
