现有技术的延时阀， 一般由带出入口的阀体、可自动复位的弹性按压杆及设于阀体 内的活塞构成， 活塞受弹性按压杆推动后退使出入口水路连通， 并在不断充满活塞腔的 水推动下复位使出入口水路关闭， 因此， 可通过设定活塞复位时间来设定座便器的储水 量。 例如授权公告号为 CN 2020563741；、 授权公告日为 2011年 11月 30日的中国实用 新型专利， 通过限定阻尼孔的大小， 以控制下阀座充水时间， 达到限定活塞复位时间， 实现对座便器冲水喷头出水量的控制。 该种延时阀结构简单， 可准确控制水量， 但却无 法根据不同楼层供水压力不同而临时调节出水量，从而造成由于高楼层因水压低而冲水 喷头出水量不够， 而不能将座便器冲干净。 实用新型内容
本实用新型的目的在于提供一种能根据不同楼层的不同水压进行调节， 使冲水喷 头能按座便器所需冲水量出水， 即节约用水又满足卫生指标要求的座便器。

本实用新型座便器， 通过在冲水喷头与外部自来水管相连管路上设有延时阀， 延时 阀的弹性按压杆侧端设置行程调节件， 调节弹性按压杆下压距离， 以改变阀体内的活塞 复位时间， 从而改变延时阀的出水量， 进而改变冲水喷头的出水量。 由此可根据不同楼 层的不同水压调节行程按压杆的位置高度， 改变延时阀的出水量， 使得冲水喷头按座便 器所需冲水量出水， 既节约用水， 又可确保将座便器冲干净， 满足卫生指标要求。
在一些实施方式中，支撑架可以包括一活动杆及一固设于阀体出口或入口处的固定 杆， 活动杆一端枢接于固定杆上， 另一端与冲水启动件连接。
在一些实施方式中，行程调节件可以设于活动杆上以随活动杆转动而按压弹性按压 在一些实施方式中， 行程调节件可以为螺钉， 通过螺母设于活动杆上。
在一些实施方式中，延时阀还可以包括用于调节形成行程调节件位置高度的调节螺 在一些实施方式中， 还可以包括三通管和密封阀， 三通管与设在盆体下方的排污口 连通， 密封阀内置于三通管上部， 密封阀包括两部分， 一部分为顶端封闭的圆筒体， 圆 筒体的底端边缘设有凹口， 另一部分为通过螺纹与圆筒体底端旋紧的底盘， 底盘中心设 有伸入到圆筒体内部的排水管， 排水管管壁上部设有供盆体内多余的水排出的防溢孔。 由此使得当盆体内的水位升高到一个固定值后，便可通过密封阀将盆体内多余的水自动 排出， 而下水道里的液体或者气味也无法向上冒出， 具有多重防臭的效果。提高了本实 用新型座便器的实用性。

下面结合附图对本实用新型作进一步详细的说明。
图 1示意性地显示了根据本实用新型的一种实施方式的座便器。 如图 1所示， 该座便器包括盆体 1、 冲水喷头 2及延时阀 3。 此外， 还包括三通管 4、 密封阀 5、 冲水启动件 6和水控阀 7。
冲水喷头 2设在盆体 1后上方。延时阀 3和水控阀 7安装在冲水喷头 2与外部自来 水管相连管路上。三通管 4内置于盆体 1内， 与开设在盆体 1下方排污口 101连通。 密 封阀 5， 内置于三通管 4上部。 密封阀 5的下部外围套有环形密封圈 8。 冲水启动件 6 通过联动杆 9与延时阀 3、 密封阀 5连接。 具体来说， 就是冲水启动件 6活动连接联动 杆 9， 联动杆 9的一端活动连接密封阀 5的顶端， 另一端连接延时阀 3。
如图 2所示， 冲水喷头 2为三向喷头， 为 T型管状结构， 其竖管的一端为进水口 201， 横管的管壁上设有若干个供水喷出的微孔 202， 横管的两端端部分别开有供水喷 出的喷口 203。 进水口 201的孔径大于喷口 203的孔径。
如图 3所示， 延时阀 3包括带出入口的阀体 301、 设于阀体内的活塞及与活塞联动 的弹性按压杆 302。 阀体 3上架设有支撑架， 支撑架上设有与弹性按压杆 302活动连接 用于调节弹性按压杆 302下压距离的行程调节件 303。 支撑架包括活动杆 304及固设于 阀体 301出口或入口处的固定杆 305。 活动杆 304—端枢接于固定杆 305上， 另一端与 冲水启动件 6连接。行程调节件 303通过固接在活动杆 304上以随活动杆 304转动而按 压弹性按压杆 302。 本实施例中， 行程调节件 303为螺钉， 通过定位螺母 306定位行程 调节件 303在活动杆 304上的位置， 行程调节件 303相对于活动杆 304上下移动， 通过 调节螺母 307固定行程调节件 303的高度位置。将延时阀 3安装在座便器上时， 用户可 根据不同楼层的不同水压调节行程调节件 303的位置高度，由此可改变延时阀 3的出水 量， 使得冲水喷头 2能按座便器所需冲水量出水。
如图 4所示， 三通管 4为 T型管， T型管平行于水平面的管体与垂直于水平面的 管体衔接形成一个衔接口 401， 在衔接口 401靠近地面一侧垂直于水平面的管体上设有 防止密封阀 5下滑的锥形卡口 402。
如图 5所示， 密封阀 5包括两部分， 一部分为顶端封闭的圆筒体 501， 圆筒体 501 的底端边缘设有凹口 502， 另一部分为通过螺纹与圆筒体 501底端旋紧的底盘 503， 底 盘 503设有伸入到圆筒体 501内部的排水管 504， 排水管 504与底盘 503连通并注塑为 一体， 排水管 504管壁上部设有供盆体 1内多余的水排出的防溢孔 505。 圆筒体 501与 底盘 503通过螺纹连接成一体， 凹口 502处于三通管 4的锥形卡口 402之上， 使得下水 道里的恶臭味或者是漂浮物就很难进入到盆体 1内， 起到了防臭的作用。
冲水启动件 6可以为脚踏板或手动拉杆。 本实施例中， 为脚踏板。
本实用新型座便器进行冲水时， 用户向下踩压冲水启动件 6后， 与冲水启动件 6连 接的联动杆 9的一端提起密封阀 5， 一端带动延时阀 3的活动杆 304使延时阀 3处于打 开状态， 此时， 盆体 1底端内部的排污口 101与三通管 4的衔接口 401连通， 自来水通 过水管依次流经水控阀 7和延时阀 3后进入冲水喷头 2内，当水通过进水口 201进入冲 水喷头 2内后， 水流分三个方向向外喷出， 一个方向为直接向前喷出的微孔 202， 其余 两个方向为喷口 203， 两个喷口 203可分别环绕盆体 1两侧的内壁进行喷淋冲洗， 由此 使得盆体 1的内壁可以被同时全方位的进行喷洗。所有污物借助自然力和水流的负压瞬 间通过三通管 4排走。 当松开冲水启动件 6后， 冲水启动件 6复位， 同时密封阀 5由于 自然重力的影响垂直滑落至三通管 4的锥形卡口 402处， 延时阀 3同时复位， 此时， 延 时阀 3由于延时继续有水流通过冲水喷头 2喷出至盆体 1， 而密封阀 5堵塞住三通管 4 的衔接口 401使盆体 1内的水不再排出， 持续 3-5秒后， 盆体 1内形成了由自来水形成 的水封 10。 当盆体 1 内的水过多时， 水流通过密封阀 5上的凹口 502流入到密封阀 5 内， 当密封阀 5内的水位上升至防溢孔 505后， 密封阀 5内的水便流经防溢孔 505后通 过排水管 504排出。 由于防溢孔 505的位置决定了盆体 1内水封水位的高度， 因此， 盆 体 1内水封的最高水位便可被确定，并且由于密封阀 5堵塞住了三通管 4的衔接口 401， 下水道里的恶臭味或者是漂浮物就很难进入到盆体 1内， 因此， 密封阀 5与水封便起到 了多重防臭的效果。
以上所述的仅是本实用新型的一些实施方式。对于本领域的普通技术人员来说， 在 不脱离本实用新型创造构思的前提下， 还可以做出若干变形和改进， 这些都属于本实用 新型的保护范围。
