The existing patent No. is the one of CN201120529319.5 simple and easy pair of float valve platform basin wastewater-reutilizing tank of water closet, its technical scheme is: a kind of simple and easy pair of float valve platform basin wastewater-reutilizing tank of water closet, comprise casing, flushing switch, bath start arm and transmission arm, bulb stopper, bleed off pipe, guiding fixing device on transmission arm and the tap water supply pipe be connected with casing, tap water supply pipe water tank end is provided with water filling port, float valve, waste water ball float and floating arm assembly, also be provided with clamp and be positioned at waste water ball float and floating arm assembly upper end, described bleed off pipe is connected with water outlet of water tank, bleed off pipe end is provided with overfall, also comprise the platform basin Sewage treatment pipe be connected with casing, platform basin Sewage treatment pipe water tank end is provided with water filling port, float valve, waste water ball float and floating arm assembly, described overfall is lower than the water filling port of platform basin Sewage treatment pipe.But it only uses two ball floats, realize classification control water, water seal plug can not be solved and again block delivery port, occur the problem discharged water not to the utmost.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of negative pressure buffer-type automatic flushing device.
The technical solution of the utility model is: negative pressure buffer-type automatic flushing device, comprise: casing, first ball float, second ball float, water control device, water inlet pipe, communicating pipe, overflow pipe, dashpot, outlet pipe, button, it is characterized in that: in water tank, be provided with a water control device, a button is provided with above water control device, a spring is provided with below button, button end connects a pole, pole is provided with a lever, lever end is connected with sealing-plug, one communicating pipe was installed below sealing-plug, dashpot is connected by communicating pipe with water control device, the first ball float is provided with in dashpot, piston and water seal plug is connected with below first ball float, a negative tube is connected with above dashpot, below is connected with an outlet pipe, dashpot right part is provided with overflow pipe, overflow pipe end is provided with an overfall gap plug, overfall gap plug connects the second ball float by fly rod.
Described negative tube one end connects dashpot, and the other end is connected with outlet pipe, and dashpot is connected by outlet pipe with outside atmosphere.
Vertically height is higher than communicating pipe and overflow pipe for described dashpot, and communicating pipe and overflow pipe are in same level.
Good effect of the present utility model is:
1, negative tube one end connects dashpot, and the other end is connected with outlet pipe, and dashpot is connected by outlet pipe with outside atmosphere, and by forming negative pressure, slow down water seal plug decrease speed, prevents water seal plug from again blocking delivery port, occur situation about discharging water not to the utmost.
2, the utility model structure is simple, and cost is low, is beneficial to and promotes on a large scale.
