Description

一种座便器排臭水封装置 技术领域
本发明属于卫生洁具用品，涉及一种座便器排臭及水封装置，能确保臭气在任何情况不能返流的功能。
背景技术
近年来，随着人们对生活卫生要求的提高，各种智能座便器受到了消费者的亲睐，市场火爆，因此座便器排除臭气的功能也越发重要，虽说各种排除臭气的技术也都有问世，包括我们也曾经申请了几个相关技术的专利，近期在研发过程中，我们发现有一装置不但有能将臭气吸出排入下水道的功能，还有可靠的返流水封的功能。其结构更加简单，造价更低，质量更可靠。
发明内容
本发明提供一种结构更简单、更可靠的，各项功能都能满足座便器冲洗功能的一种座便器排臭水封装置，不仅能将座便器臭气排入座便器下水道，并能确保在任何情况下都能防止下水道中的甲烷气体返流至卫生间的功能。
本发明的一种座便器排臭水封装置安装在座便器水箱中，由排气组件、水封返流组件和电子控制组件组成。本装置有一台强力排气电机，启动后，电子控制组件向排气电机供电，排气电机能将便盆中的气体吸入水箱，通过排气电机将排气压力提高，气压将U型存水水封中的水推压出，流入排气管，水与气体从座便器S弯排污管排入下水道，当座便器排污时，电子控制组件自动切断电源，排气电机停止工作，U型存水水封失压，水箱中的存水通过进水腔迅速流入U型存水水封中产生水封，即时阻断气体回流，同时也确保了便器在排污时产生虹吸功能。
本发明是通过如下技术方案实现的：
本发明一种座便器排臭水封装置是由排气组件、水封返流组件和电子控制组件组成的。本装置安装在座便器的水箱中，伸缩套管穿过水箱底部，有一连接管连通座便器S弯排污管，调整装置上的水位线与水箱水位等高，接通电源。
如厕时，启动电源开关，通过电子控制组件启动排气电机，在高转速下，排气电机将水箱内的空气吸入排气电机，此时，水箱内产生负压。因此座便器坐腔中的气体顺排水环型槽进入排水阀上的溢流管进入水箱，如厕时的臭气也随气体流动进入水箱，由于排气电机的气压大于座便器S弯水封高度的水压，因此，水封组件中的水封腔①的水面受压向下挤压，直至将水封腔①中的水从水封腔底部压入水封腔②，并溢过排气管口，流入座便器S弯排污管。此时，受气压的影响气体也将进水腔中的水同时向下挤压至U型存水杯底部，由于气压的平衡作用，水封腔①中的气体通过水封腔底部的通道流入水封腔②，气体顺水封腔②向上冒起流入排气管，进水腔中的水面与水封腔底部的水面持平。因为n型排气罩口低于U型存水杯底部，所以气体不会从n型排气罩底部排出，只能通过水封腔①和水封腔②排入排气管。
当如厕完，座便器排水时，排水阀开启，水箱水位迅速下落，此时在水面上的水位开关，将排气电机电源切断，排气电机停止工作，水封腔①和进水腔中的气压立即消失，由于水箱中的水位仍然处于高位，在水压的作用下，水即从进水腔进入水封腔①和水封腔②形成U型存水水封，直到水封腔内的水封水面与水箱水面持平；当排水继续，水箱水位下降低于U型存水杯口时，U型存水杯中的水不再流出，水封保持在设定的高度，以保证座便器冲水时S弯排污管有足够的虹吸力将污物吸走的功能。

具体实施方式
现结合附图说明和具体实施方式对本发明进一步说明。
现结合图1对本发明作进一步的说明。本发明一种座便器排臭水封装置是安装在座便器水箱中，由排气组件、水封返流组件和电子控制组件组成。伸缩套管4穿过水箱底部，有一连接管17连通座便器S弯排污管，调整装置上的水位线8与水箱水位等高，电源开关18和电子程序控制器19安装在水箱上，接通电源20。
现结合图2、图3对本发明产品结构作进一步说明。本发明的一种座便器排臭水封装置安装在座便器水箱中，由排气组件、水封返流组件和电子控制组件组成。排气组件由n型排气罩1、排气电机2、排气管3、伸缩套管4组成；水封返流组件则由U型存水杯5、n型水封罩6、排气管3组成；电子控制组件由电源20、电源开关18、电子程序控制器19、水位开关10组成。
所述的排气组件由n型排气罩1扣在排气电机2和水封返流组件上，排气电机2坐落在水封返流组件上方的n型排气罩1内的顶部，排气电机2与n型排气罩1间隙形成导气腔，n型排气罩1顶部开有进气口7、n型排气罩1将水封返流组件全部罩住，并伸出低于水封返流组件的U型存水杯5底部，n型排气罩1外壳上部标有水位线8，水位线8设置在高于U型存水杯5的杯口低于排气管口9，水位线8处设有水位开关10，当水平面到达水位线8，水位开关10则导通排气电机2；当水平面低于水位线8，水位开关10则切断排气电机2电源20。
所述的水封返流组件以排气管3为主体，排气管3穿过U型存水杯5成为一体，排气管口9高于水位线8，n型水封罩6扣在排气管3和U型存水杯5之间的空腔中形成水封腔①11、水封腔②12，水封腔①11与水封腔②12底部留有空腔相连通形成U型存水水封；n型排气罩1与U型存水杯5之间的空腔形成进水腔13；水封腔①11、水封腔②12、进水腔13和排气管3的截面积基本相等；水封腔①11、水封腔②12、进水腔13连通形成M型空腔；n型排气罩1、排气管3、U型存水杯5和n型水封罩6有支架14相互支撑且不影响气体和水的流动。
所述的电子控制组件用导线将电源20、电源开关18、电子程序控制器19、水位开关10分别串联在一个电子回路中。
现结合图1、图4本发明作进一步说明。如厕时，启动电源开关18，通过电子控制组件启动排气电机2，在高转速下，排气电机2将水箱内的空气吸入排气电机2，此时，水箱内产生负压。因此便盆中的气体顺排水环型槽进入排水阀上的溢流管进入水箱，如厕时的臭气也随气体流动进入水箱，由于排气电机2的产生的气压大于座便器S弯水封高度的水压，因此，水封组件中的水封腔①11和进水腔13的水面受压向下挤压，直至将水封腔①11中的水从水封腔底部压入水封腔②12，并溢过排气管口9，流入座便器S弯排污管。此时，受气压的影响气体也将进水腔13中的水同时向下挤压至U型存水杯5底部，由于气压的平衡作用，水封腔①11中的气体通过水封腔底部的通道流入水封腔②12，气体顺水封腔②12向上冒起流入排气管3，进水腔13中的水封水面15与水封腔底部的水面持平。因为n型排气罩1口低于U型存水杯5底部，所以气体不会从n型排气罩1底部排出。
现结合图5对本发明进一步说明。当如厕完，座便器排水时，排水阀开启，水箱水位迅速下落，此时在水面上的水位开关10，将排气电机2电源20切断，排气电机2停止工作，水封腔①11和进水腔13中的气压立即消失，由于水箱中的水位仍然处于高位，在水压的作用下，水即从进水腔13进入水封腔①11和水封腔②12形成U型存水水封，直到水封腔内的水封水面15与水箱水面16持平。
现结合图6对本发明进一步说明。排水继续，水箱水位下降，进水腔13中的水随水箱水面16降落至U型存水杯5口后，U型存水杯5中的水不再流出，保持U型存水杯5中的水面在所设定的水封水面15的高度上，以保证座便器冲水时S弯排污管有足够的虹吸力将污物吸走的功能。
以上所述，仅为本发明的较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
