Abstract

Provided are a double-gear flapper type drain valve and a water tank device. The drain valve comprises a base, a flapper, a fixing frame, a lifting mechanism and a key mechanism. The base is provided with a water outlet. The key mechanism is provided with a large-gear key and a small-gear key. One end of the lifting mechanism is in transmission connection with the key mechanism, and the other end of the lifting mechanism is connected with the flapper to lift or loosen the flapper. The flapper is rotatably connected with the fixing frame. The drain valve further comprises a counterweight mechanism. The counterweight mechanism is rotatably connected with the flapper and is at a front limiting position when the flapper closes the water outlet. A stop piece capable of moving relative to the fixing frame is further arranged and is in transmission connection or contact with the large-gear key, so that when the large-gear key is pressed to lift the flapper, the counterweight mechanism is made to rotate to a rear limiting position, and therefore the flapper is kept at a first opening position to achieve long drainage time, or when the small-gear key is pressed to lift the flapper, the counterweight mechanism is blocked and kept at the front limiting position, so that the flapper is kept at a second opening position to achieve short drainage time. The double-gear flapper type drain valve and the water tank device have the advantages of few parts, simple structure and low cost.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a dual-stage clapping cover type drain valve and a water tank device. Background technique [0002] Existing common toilet drain valve is mainly divided into flap valve and cylinder valve two kinds. The flap valve has a simple structure and low cost, but usually only has a single-stage flushing function. Cartridge valves usually have a double-shift function (that is, a large shift and a small shift correspond to stool and urine flushing respectively), but the structure is complicated and the cost is high. [0003] At present, most users tend to choose toilets with dual flushing, so the cartridge valve is widely used. In order to reduce the cost, there is an attempt to increase the double-speed function on the basis of the flap valve. For example, slidable full-row weight buoys and half-row weight buoys are set on the overflow pipe. Sliding skateboard, when fully rowing, hang the ...
