摘要： A toilet having a one piece structure, a flush valve, and a seal. The structure includes a base having a fluid channel in fluid communication with a bowl; a tank having an internal compartment; a wall disposed between the tank and the base, the wall having an opening fluidly connecting the internal compartment and the fluid channel; and a retaining structure in the internal compartment. The flush valve has a valve body including an inner wall, which is disposed in the opening and extends from a first end in fluid communication with the internal compartment to a second end in fluid communication with the fluid channel, and a locking flange extending radially outward from the inner wall, the locking flange being retained between the retaining structure and the wall in a locking position. The seal is disposed between the locking flange and one of the wall or the retaining structure.

摘要： A flush mechanism for a toilet with a tank can include a float basket with a drainage port and at least one peripheral wall. A flexible conduit can be secured to the float basket to provide a liquid flow path from the drainage port to a flush port of the tank. The drainage port can be disposed eccentrically within the float basket, a top profile of the at least one peripheral wall can be inclined, or a rotatable collar can be provided to control flow of water into the drainage port.

摘要： A grey water toilet system utilizing a pedal interface to trigger the toilet flush and to resupply the toilet tank with grey water. The grey water is generally collected from a nearby water fixture such as a wash basin and placed in a storage reservoir until the user flushes the toilet. This invention can be used to retrofit most existing toilets without the need for remodeling thus making it possible to expand the use of grey water for toilets, potentially leading the way for significant fresh water savings. It is estimated that the average American residence uses in the range of 100,000 gallons of water annually and that more water is used to flush toilets than any other individual activity.

摘要： A tube device including concentric inner and outer tubes to form an annulus to receive an upright stem in a toilet tank and adjustable relative to the stem. A keeper limits travel of a float to prevent opening of a control valve absent flushing of the toilet.In one aspect, the present invention includes an elongated catch device pivotally mounted intermediately to an inlet tube device and carrying at its upper extremity a keeper selectively disposed in the path of a float device to, unless a toilet has been flushed, block lowering of the float device and consequent opening of the control valve.

摘要： A water inlet valve includes a water sealing piston installed in a water inlet pipe and a top cover. A water storage cylinder is fixed outside the water inlet pipe. A lower water cavity has an upper air vent and a lower water inlet. A siphon is arranged in a water storage cavity and communicated with the lower water cavity. A first magnetic element is arranged on a floater. A small buoy is arranged outside the water storage cylinder to open and close the upper air vent. A gutter is formed on the periphery of the top cover. A lever and an eccentric shaft are arranged outside the water inlet pipe and the top cover. The connecting rod is connected with the lever and the eccentric shaft. The lever is provided with an energy storage spring, a second magnetic element, and a restoring spring.
