The invention discloses a drainage device of a closestool. The drainage device comprises a water tank; the drainage valve is arranged in the water tank, the drainage valve comprises a valve body provided with a drainage port, a valve element movably arranged in the valve body and matched with the drainage port in an opening and closing mode and a control floating barrel movably arranged in the valve body, a negative pressure cavity is defined by the control floating barrel and the inner wall of the valve body, the negative pressure cavity is communicated with an inner cavity of the water tank, and the control floating barrel is in transmission connection with the valve element; the water pumping mechanism is used for pumping out water in the negative pressure cavity so as to control the floating barrel to float and drive the valve element to move in the direction of opening the water outlet; the hydraulic mechanism comprises a hydraulic cavity and a piston matched with the hydraulic cavity, and the piston is in transmission connection with the valve element; the water supply mechanism is used for supplying water to the hydraulic cavity so that the piston can move and drive the valve element to move in the direction of opening the water outlet. The drainage device of the closestool can effectively improve the accuracy of the drainage amount, and is simple and reliable in structure.
本发明公开了一种马桶的排水装置，包括：水箱；排水阀，设于水箱内，排水阀包括设有排水口的阀体、活动设于阀体内并与排水口开闭配合的阀芯和活动设于阀体内的控制浮桶，控制浮桶与阀体的内壁围成一负压腔，负压腔与水箱的内腔相连通，控制浮桶与阀芯传动连接；抽水机构，用于将负压腔内的水抽出以使得控制浮桶浮起并带动阀芯往打开排水口方向运动；液压机构，包括液压腔和与液压腔相配合的活塞，活塞与阀芯传动连接；供水机构，用于对液压腔进行供水以使得活塞活动并带动阀芯往打开排水口方向运动。本发明的马桶的排水装置能够有效提高排水量的精准度，结构简单、可靠。
