Toilet flushing systems installed in a toilet reservoir. A toilet reservoir stores a fluid that pours into a toilet bowl for carrying waste away from a toilet. Exemplary toilet flushing systems may include a flush sleeve having a sleeve bottom and sleeve top. The exemplary sleeve bottom may connect to a bottom of the toilet reservoir around a reservoir drain. The flush sleeve may be capable of being raised in a raised orientation such that the sleeve top is above the fluid in the toilet reservoir to prevent the fluid from entering the reservoir drain. Exemplary toilet flushing systems may include a flush sleeve actuator that lowers the sleeve top of the flush sleeve below a fluid level in the toilet reservoir to allow the fluid to flow through the flush sleeve into the reservoir drain.

The present invention relates to a hygienic toilet comprising a source of hot and cold water; a thermostatic valve in fluid communication with the source of hot and cold water and having a single output to deliver water at a predetermined temperature; a manifold having an input for receiving the water output from the thermostatic valve, the manifold comprising a first water outlet controlled by a proportional control valve and a second water outlet; a washing nozzle in fluid communication with the first water outlet, and having a proportional control valve associated therewith to control the flow of water output from the washing nozzle; and a cleaning nozzle in fluid communication with the second water outlet for providing a water curtain within an interior of the toilet; wherein the water curtain flows over the washing nozzle.

A toilet flush lever assembly having an adjustable length internal lever arm with a variable angle of connection to a short arm that passes through the wall of the toilet tank such that the angle of mounting of the adjustable length internal lever arm to an external flush lever arm is adjustable.

An extender for a push-button and/or motion sensor toilet flush actuator, has a fulcrum member for mounting on a rim of a tank of the toilet and a sleeve for slidably receiving a rigid extension rod, which has an angular bend between the first rod end and the second rod end. An extender head is connected to one end of the rigid extension rod is adapted to engage the flush actuator. A lever arm is connected to the other end of the rigid extension rod for operation of the extender by a user's upper extremity, so that when the user applies pressure to the second lever end of the lever arm, the rigid extension rod moves to allow the extender head to engage the flush actuator.

A discharge valve operating device includes an electric operation unit including a rotating shaft, a first coupling member and a second coupling member having respective one ends coupled to a discharge valve, a first rotary winding member, and a second rotary winding member. The first rotary winding member and the second rotary winding member include a first holed portion and a second holed portion, respectively, which are provided near portions at respective rotation centers. Each holed portion is engageable and disengageable with the rotating shaft in a rotation direction in accordance with the rotation direction of the rotating shaft in each operation mode.

A rotatable toilet tank lever equipped with a stopper has a controller to limit its upward movement. When engaged, the upward movement of the controller is stopped by an adjustment stick hitting the cover of toilet water tank. Therefore, the upward movement of the flapper inside the toilet tank is also limited and the amount of water, about half a gallon, draining into the toilet suffices to flush liquid human waste. When the intervention of the controller is eliminated by turning the handle of the rotatable toilet tank lever with controller clockwise 90 degrees to 180 degrees then the flapper can be lifted all the way up to float in the toilet water tank to allow the whole tank of water, about two gallons, to drain into the toilet bowl to flush solid human waste.
