A water reuse device for reusing waste water discharged from a bathroom or a kitchen as toilet flushing water, including: a water collecting tank (10); a storage tank (20) receiving the used water stored in the water collecting tank (10) and having a water level sensor (21); a toilet water tank (32) located at a lower level than the storage tank (20) and having a first water level sensor (36) and a second water level sensor (35); a first pipe (22) connecting the storage tank (20) and the toilet water tank (32); a first solenoid valve (40) installed in the first pipe (22); a second pump (38) installed in the toilet water tank (32); a backflow prevention valve (34) provided between the second pipe (33-2) and the third pipe (33-3); and a water shutoff valve (41) provided between a water supply pipe (31) and the water pressure control valve (41-1).

A flush lever comprises a handle and a skirt, or escutcheon plate, both disposed to the exterior of a toilet tank. Within the tank is a flush lever subassembly, the subassembly taking one of two different embodiments and each embodiment comprising means for mechanically linking the flush lever with the subassembly. One portion of the flush lever can be variably adjustable within 360° of rotation and by adjustments every 15° for optimal placement of the flush lever as desired or required. Another portion of the flush lever can be variably adjustable within 180° of rotation as well and by adjustments also every 15°.

The front end of a pipe is placed in the air flow zone formed by a compressed air tube, and the back end of the pipe connects to the urine source. When the compressed air passes through the front end of the pipe, a spray is formed that can flush fecal waste. The embodiments in this application also describes an extension pipe that can connect between back end of the pipe and the urine source, which makes flushing of fecal waste easier in straight toilets. This application's embodiments also describes a nozzle for the pipe and a nozzle for the compressed air tube.

A straight toilet device using urine as flushing liquid, comprising: a container; a liquid inlet port connected to container, with a unidirectional valve placed at the inlet; a liquid outlet port connected to container and a raised pipe; a compressed air inlet port connected to container. The urine used for flushing passes through liquid inlet port, entering container. Compressed air enters container from compressed air inlet port. Urine is pressurized, exiting liquid outlet port at high speeds, flushing away solid waste and dirt.

Pull-out sprayhead (1) for a faucet, comprising: an inlet fitting (10) provided with a coupling end (11a) which can be connected to an extractable water supply pipe; a supply mouth (10d) in fluid communication with said coupling end (10d); and a magnet (12) fixed at the inlet fitting (10) and designed to allow releasable connection of said pull-out sprayhead (1) to a faucet neck (20), said magnet (12) being arranged in a watertight housing chamber (13) defined between an outer wall of said inlet fitting (10) and a covering nut (14) fastened to said inlet fitting (10).

Certain exemplary embodiments can provide a system, which comprises a turbine wheel assembly. The turbine wheel assembly comprises a turbine wheel compartment. The turbine wheel compartment is constructed to be coupled to a fan. The fan can be coupled to a cartridge. The turbine wheel compartment is coupleable to a toilet fill valve assembly such that the turbine wheel assembly is housed within a toilet tank. The turbine wheel assembly comprises a turbine wheel.

A toilet tank washbasin and faucet system that rests on top of a toilet tank is described by way of example. The faucet dispenses water intended to fill the toilet tank over a drain that leads into the toilet tank. The faucet is useful to a person for washing their hands with the water dispensed from the faucet to advantageously provide a second use of the water before flushing down the toilet. Generally described is a basin that sits atop an open toilet tank. A faucet having a nozzle end is attached to the basin via a keyed member that a) positions the nozzle end over a drain in the basin and b) prevents rotation of the faucet when attached to the basin, the drain leads into the toilet tank. Water is provided to a flexible tube that attaches to a bowl refill tube. The flexible tube extends through the faucet and terminates essentially at the nozzle end.

A cistern comprises an upper water tank as a first chamber, and a lower water tank as a second chamber connected by an opening. At the top of the upper tank a mains water inlet allows mains water into the tank through an inlet valve, which is under the control of an upper float. An auxiliary water inlet allows water from an auxiliary supply, such as condensate from an air-conditioning unit, into the tank. At the bottom of lower tank is an water outlet, which allows flushing water from the lower tank 104 to flush an appliance (not shown) under the control of an outlet valve. The outlet valve is under the control of an actuator, which is configured to move up and down, and is also under the control of a lower float.

A flush toilet comprised of a tank having a first compartment for holding a first type of water, and a second compartment for holding a second type of water. The first compartment is separated from the second compartment by a divider that prevents the first type of water from mixing with the second type of water. The first type of water can be city water while the second type of water can be rainwater.
