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 floating barrel movably arranged in the valve body, a negative pressure cavity is defined by the 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 floating barrel is in transmission connection with the valve element; an inlet of the water pump is communicated with the negative pressure cavity, an outlet of the water pump is communicated with a flushing water path of the closestool, when the water pump is started, water in the water tank is pumped into the flushing water path through the negative pressure cavity, and negative pressure is formed in the negative pressure cavity, so that the floating barrel can float under the action of buoyancy to drive the valve element to open the water outlet; after the water level in the water tank drops to a preset position, the floating barrel drops under the action of gravity to drive the valve element to close the water outlet. The power requirement on the water pump can be effectively reduced, the cost of the water pump is reduced, the structure is simple, and the function is reliable.
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浮桶，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，浮桶与阀芯传动连接；水泵，水泵的进口与负压腔相连通，水泵的出口与马桶的冲洗水路相连通，水泵开启时通过负压腔将水箱内的水抽至冲洗水路并且在负压腔内形成负压，从而使得浮桶在浮力作用下能够浮起以带动阀芯打开排水口；水箱内的水位下降到预定位置后，浮桶在重力作用下下落以带动阀芯关闭排水口。本发明能够有效降低对水泵的功率要求，降低水泵的成本，并且结构简单、功能可靠。
