Flush toilet and flapper type drain valve thereof
The invention relates to a flush toilet and a flapper type drain valve thereof, and the flapper type drain valve comprises: a base which comprises an upward drain port, a support arranged on one side of the drain port and a rotating shaft with one end connected to the support and the axis horizontally arranged; a flapper which is arranged above the drain outlet and can cover the drain outlet; a connecting rod, wherein one end of the connecting rod is connected to the flapper, the other end of the connecting rod is provided with a shaft hole sleeving the rotating shaft, and the extending direction of the connecting rod is perpendicular to the axis of the rotating shaft; and an opening piece which is connected to the side, away from the rotating shaft, of the flapper, wherein the shaft hole is a strip-shaped hole, the extending direction of the shaft hole is perpendicular to the extending direction of the connecting rod, and when the flapper covers the drain outlet, a receding gap is formed between the upper side wall of the shaft hole and the rotating shaft. The flapper type drain valve is simple in structure, high in reliability and more labor-saving in opening.
一种抽水马桶及其拍盖式排水阀，该拍盖式排水阀包括：底座，包括朝向上方的排水口、设置在所述排水口一侧的支座以及一端连接于所述支座上且轴线水平设置的转轴；拍盖，设置在所述排水口的上方且能覆盖所述排水口；连杆，一端连接于所述拍盖，另一端设置有套在所述转轴上的轴孔，其延伸方向垂直于所述转轴的轴线；开启件，连接于拍盖背离所述转轴的一侧；其中，所述轴孔为条形孔，所述轴孔的延伸方向垂直于连杆的延伸方向，在所述拍盖覆盖所述排水口时所述轴孔的上侧壁与所述转轴之间形成让位间隙。这种拍盖式排水阀的结构简单、可靠性高，且开启时更加省力。
