摘要： A plumbing device for a basin drainage includes a pushbutton, a spring, a positioning sleeve, a probe and a seal that is connected to the probe. The pushbutton is able to control the movement of the seal to selectively communicate the inlet and the valve receiving channel. A moving chamber is movably received in the pressure chamber to control the communication between the pressure release path and the passage of the cap. The accumulated pressure in the pressure chamber is able to be released by pushing the pushbutton so as to generate a large force into the drainage with the suction cup securely engaged with the periphery of the drainage.

摘要： A plunger device for unclogging a toilet drain includes a housing which is elongated and has a open first end and an open second end. A peripheral wall extends between the first and second ends. The first and second ends are generally circular. The first end has a smaller diameter than a diameter of the second end. The diameter of the second end is larger than a toilet drain. A may be used for forcing air into the housing and is removably in communication with the first end of the housing. The second end of the housing is positioned over the toilet drain such that air is moved from the pump and into the housing causing water in the toilet to be forced into the drain and unclogging the drain.
摘要翻译：一种用于开启厕所排水沟的柱塞装置包括一个细长的壳体，它具有开放的第一端和开口的第二端。周壁在第一和第二端之间延伸。第一和第二端通常是圆形的。第一端具有比第二端的直径小的直径。第二端的直径大于厕所排水口。 A可以用于迫使空气进入壳体并且可移除地与壳体的第一端连通。壳体的第二端定位在马桶排水口上方，使得空气从泵移动到壳体中，使得马桶中的水被迫进入排水管并排出排水管。
