一种双控式冲水机构 技术领域
本发明涉及卫生器具技术领域，具体涉及一种双控式冲水机构。
背景技术
目前，传统的坐便器冲水装置通常是在水箱上设置按键来控制冲水与否，即手动控制，这也导致水箱按键容易滋生细菌，同时需要弯腰操作，为冲厕带来不便。
现有技术中的一种厕所冲水装置，其带有自动冲水功能，通常是在马桶体的设计位置布置传感器，如红外传感器，当红外传感器感应用户离开后，即通过信号控制冲水装置工作，将阀门打开进行冲水，无需用手冲水，使用方便，然而，该种冲水装置由于传感器的设置，不可避免的需要额外连接电源和电控装置，马桶侧的附近需要设置电源插接口，长期使用时后也难以保障电控装置的正常工作，且该种冲水装置成本较高，不利于公共厕所使用；
现有技术中的另一种厕所冲水装置，其在上述自动冲水装置的基础上额外增加了脚控式的冲水方式，传统的按键冲水装置包括阀体和设于阀体内的阀杆，阀杆是设置在阀体的中部，并通过按键来控制阀体的相对打开，而为使得脚控式结构的传动部件与中部的阀杆构成传动连接，需取消传统的按键式冲水装置，改变传统的阀体结构，造成研发和制造成本的浪费，在失去电源时导致冲水装置无法正常使用。

如图1-15所示，一种双控式冲水机构，包括：
主体1，所述主体1连接有水箱1.1，所述水箱1.1内设有阀门组件2，所述水箱1.1与主体1之间设有冲水口；
阀门组件2，包括阀体2.1和设于阀体2.1内的阀杆2.2，所述阀杆2.2被设置为相对冲水口运动，从而控制所述冲水口打开或关闭，所述阀杆2.2端部延伸有传动部位2.21；
第一冲水机构3，包括按压单元3.1，以及置于阀体2.1内的传动组件4，所述传动组件4包括与按压单元3.1接合的第一传动端4.1，以及与传动部位2.21接合的第二传动端4.2，第一传动端4.1与第二传动端4.2之间还设有铰接部位，通过按动按压单元3.1，以使第一传动端4.1通过铰接部位带动第二传动端4.2提升，使得阀杆2.2提升并离开冲水口，从而打开冲水口；
第二冲水机构5，包括脚控组件6，以及置于阀体2.1外的提升块5.1和牵引绳5.2，所述提升块5.1具有延伸至阀体2.1内的提升部位5.11，所述提升部位5.11承接在传动部位2.21底部，所述牵引绳5.2包括与脚控组件6连接的第一控制端5.3，以及与提升块5.1连接的第二控制端5.4，所述脚控组件6用于挤压或释放所述第一控制端5.3，以使所述第一控制端5.3与第二控制端5.4相对行进，并驱动所述提升块5.1与阀杆2.2同步提升，通过脚控组件6动作，并挤压第一控制端5.3，迫使第二控制端5.4相对向上行进，第二控制端5.4通过提升块 5.1带动阀杆2.2离开冲水口，从而打开冲水口。
具体的，所述阀体2.1上开设有供提升块5.1在其内滑动的槽道2.11。
通过采用本实施例中的第一冲水机构3和第二冲水机构5，可使用传统的阀体2.1结构，第一冲水机构3布置在阀体2.1的中部，第二冲水机构5布置在阀体2.1的外部，只需在阀体2.1上额外开设供提升块5.1在其内滑行的槽道2.11即可，在无需电控单元和连接电源的前提下实现机械双控式的出水。
如图4和图5所示，作为对第一冲水机构3的进一步实施方式，所述阀门组件2还包括设于阀体2.1顶部的阀盖，其中，按压单元3.1的数量为两个，且分别一一对应不同出水量的控制。
所述传动组件4包括铰接在阀盖下部的第一连杆4.3，以及与第一连杆4.3转动连接的第二连杆4.4，所述第二连杆4.4与传动部位2.21连接，第一连杆4.3与阀盖之间形成第一铰接部位4.5，第一连杆4.3与第二连杆4.4之间形成第二铰接部位4.6，所述第一传动端4.1构成在第一连杆4.3端部并与任一按压单元3.1承接，从而与按压单元3.1交互，所述第二传动端4.2构成在第二连杆4.4下端并与传动部位2.21连接。
作为对第二传动端4.2的进一步实施方式，传动部位2.21关于径向延伸在阀杆2.2顶部，且在传动部位2.21的中部设有第一避空位置2.22，第二连杆4.4的两侧设有凸部4.7，第二连杆4.4插入在第一避空位置2.22内，且凸部4.7支承在传动部位2.21的底部。
具体的，提升部位5.11关于第一避空位置2.22的周侧布置，从而承接在传动部位2.21的底部，并在其中部形成供第二连杆4.4底部通过的第二避空位置5.16。
第一冲水机构3的工作原理：按压单元3.1被按动，第一连杆4.3的驱动端下行，从而使第一连杆4.3另一端带动第二连杆4.4提升，通过第一连杆4.3上的凸部4.7带动传动部位2.21、阀杆2.2提升，从而实现冲水口的打开，在此过程中，第二连杆4.4上的凸部4.7通过第二避空位置5.16与提升部位5.11无干涉。
作为对脚控组件6的进一步实施方式，所述脚控组件6包括置于主体1内的安装部位6.1，以及伸出在主体1外的脚控部位6.2，该脚控部位6.2用于被交互获得一行程，第一控制端5.3与脚控部位6.2连接，其中，水箱1.1与主体1之间还设有密封组件7，牵引绳5.2穿设于密封组件7并连接在脚控组件6和阀杆2.2上。
如图15所示，在本实施例中，牵引绳5.2在安装部位6.1与密封组件7之间形成拉伸段5.23，在密封组件7与阀杆2.2之间形成提升段5.24，拉伸段5.23与提升段5.24均呈绕曲设置，第一控制端5.3形成于拉伸段5.23上，以受到来自脚控部位6.2的挤压，第二控制端5.4 形成于提升段5.24上，以获得拉伸段5.23的挤压行程而向上拱起，从而带动提升块5.1上行。
通过将脚控组件6的安装部位6.1容置在主体1内，将被操作的脚控部位6.2伸出在主体1外，且牵引上布置在主体1与水箱1.1的内部，实现脚控式冲水机构的空间优化，方便不同场景的面积规划。
作为对牵引绳5.2的进一步解释，
所述牵引绳5.2包括套管5.21和设于套管5.21内的拉线5.22，所述套管5.21一端作为固定端与阀体2.1固定，所述第一控制端5.3构成在套管5.21另一端并与脚控部位6.2连接，所述拉线5.22一端作为固定端与安装部位6.1固定，所述第二控制端5.4构成在拉线5.22另一端并与提升块5.1连接。
如图10和图13所示，具体的，所述第一控制端5.3与拉线固定端5.26之间形成第一活动段5.5，所述第二控制端5.4与套管固定端5.25之间形成第二活动段5.6，所述第一活动段5.5与第二活动段5.6呈反比设置，其中，拉线5.22长度大于套管5.21，提升块5.1的提升行程与套管5.21、拉线5.22的长度之差匹配，因提升块5.1的动作而产生的长度变化得以在上述的第一活动段5.5和第二活动段5.6中绕曲和释放。
其中，拉伸段5.23以自下往上的方式插接于水箱1.1内，提升段5.24从密封组件7处延伸至阀门组件2的上方，以自上往下的方式与阀杆2.2连接，从而使得水箱1.1内的拉线5.22套管5.21呈U型的姿态，或呈U型绕曲的姿态设置。
如图1至图3所示，进一步的，为了在完成冲水动作后提升块5.1能够回位至闭水位置，在提升块5.1与阀体2.1之间还设有拉力弹簧5.7。
作为可选的，提升块5.1底部设有供拉力弹簧5.7上端连接的上勾环，阀体2.1上设有供拉力弹簧5.7下端连接的下勾环。
作为优选的，阀体2.1上还设有供拉力弹簧5.7布置在其内的安装槽2.12，从而在提升块5.1任一竖向位置下，拉力弹簧5.7均具有容置在安装槽2.12内的部分，从而保证对提升块5.1回位作用力的稳定性。
第二冲水机构5的工作原理：
在常态下，阀杆2.2位于阀体2.1的相对下位，使得阀杆2.2与冲水口闭合，第二控制端5.4远离套管5.21的固定端，此时第二活动段5.6具有最大长度，而第一控制端5.3靠近拉线5.22的固定端，此时第一活动段5.5具有最小长度；
在操作过程中：
对于牵引绳5.2，拉伸段5.23在脚控部位6.2的作用下受到朝向提升段5.24的挤压，部 分套管5.21在挤压力的作用下进入水箱1.1内，提升段5.24获取挤压长度后具有向上提升的趋势，
对于套管5.21，由于套管5.21的固定端在阀体2.1上固定，因而提升段5.24被迫拱起，以提升段5.24上的绕曲位置的两侧获得拉直的趋势；
对于拉线5.22，由于拉线5.22的固定端在安装部位6.1上固定，使得第二控制端5.4在套管5.21的拱起趋势作用下，获得向上拉直的作用力，从而通过提升块5.1带动阀杆2.2提升，实现冲水口的打开。
此时，阀杆2.2在上述动作下被拉线5.22提升，使得阀杆2.2靠近套管5.21的固定端，以减少第二活动段5.6的长度，而第一控制端5.3在脚控部位6.2的作用下远离拉线5.22的固定端，且第一活动段5.5的长度随套管5.21动作而增加，使得拉线5.22得以在第一活动段5.5中释放，从而获得绕曲的空间，实现拉线5.22在第一活动段5.5内背离阀杆2.2绕曲并带动阀杆2.2远离冲水口。
在复位过程中：提升块5.1在拉力弹簧5.7的作用下向下回位，第二控制端5.4随阀杆2.2下降；
对于牵引绳5.2，提升段5.24在操作过程中拱起的部分段得以释放而下落，而套管5.21在提升段5.24上的固定端固定，拉线5.22的固定端在安装部位6.1上固定，迫使套管5.21在拉伸段5.23上的自由端舒张。
对于套管5.21和拉线5.22，阀杆2.2远离套管5.21的固定端，以增加第二活动段5.6的长度，此时，第一控制端5.3被迫朝向拉线5.22的固定端移动，以减少第一活动段5.5的长度，使得拉线5.22在第一活动段5.5上绕曲的部分被迫拉直，并在第二活动段5.6上得以释放，实现脚控组件6和阀门组件2的回位。
如图7所示，在另一些实施例中，为了实现第二控制端5.4与提升块的同步传动，所述提升块5.1内设有用于限定拉线5.22当前位置的型腔5.12，所述型腔5.12内设有至少一个限位卡件5.17，所述拉线5.22布置于所述限位卡件内，且所述拉线5.22通过型腔5.12可调节的伸出在型腔5.12外。
作为优选的，第二控制端上形成有固定端部5.41，限位卡件内设有供拉线置入的线槽，且固定端部关于提升方向抵接在限位卡件端面。
进一步的，型腔内限位卡件的数量为两个，两个限位卡件关于提升方向同向设置，第二控制端上形成有两个固定端部，通过该种设置，可选择的将固定端部抵接于一限位卡件或另一限位卡件端面上，从而实现第二控制端的行程调节。
