AI Technical Summary
Existing water leakage detection systems fail to differentiate between regular water usage and continuous leaks, often leading to minor flooding before activation and not addressing internal or hidden leaks, which can cause significant damage over time.
A mechanism that distinguishes between intended water flow and leakage by using an adjustable timer and sensors, automatically shutting off the water supply upon detection of any leak, regardless of size, and displaying alerts on a control panel.
Prevents damage from small to large leaks by immediately shutting off the water supply and providing timely alerts, effectively differentiating between normal flow and leakage.

Abstract
Description
[0001] DESCRIPTION
[0002] Water Leakage Control Mechanism
[0003] This invention pertains te a mechanism that distinguishes between the intended use of water flow and water leakage. When a leak is detected, it automatically shuts off the water supply to the plumbing system via an electric .switch. In a plumbing system, water flow is either controlled or purposeful and will eventually stop, or it is a continuous leak, that persists until it is noticed.
[0004] The water leakage control mechanism starts monitoring from fee smallest flow, such as a single drop, to an excessive flow. Using an. adjustable timer, it measures the flow duration. If the set duration is exceeded, the mechanism closes the electric switch, identifying the flow, whether small or large, as a leak.
[0005] The expected flow duration for regular use (e.g., sink, dishwasher, washing machine, toilet, or faucet) typically does not exceed 3-5 minutes.
[0006] Automatic water shut-off is also achieved through floor moisture sensors placed under sinks, water heaters, and other fixtures. When they detect, water, they electronically signal the central control mechanism to shut off the water supply. However, this method often results in minor flooding before activation and does not address internal wail leaks, solar water heaters on rooftops, boiler rooms, or small, hidden leaks, Such hidden, issues may only become apparent over time through moisture signs or increased water bills.
[0007] The proposed water leakage control mechanism immediately activates upon detecting the first leak, whether small or large. It shuts, off the water supply and displays an alert on the control panel indicating a leak in fee plumbing system.
[0008] The primary advantage of the water leakage control mechanism is its ability to prevent small to large leaks that could cause significant damage to the home or result in excessive water consumption.
[0009] The water leakage control mechanism, as described in this invention, consists of: water supply from the network (diagram 1), main supply switch (2, diagram 2) for manual operation to open and close the mechanism , sealed chamber (22, diagram. 1) to absorb, pressure surges, water filter (3, diagram .1) for retaining dirt and other particles, nop- return valves (4, diagram 1) .for stabilizing the water chamber (18, diagram 1), pressure gauges (5 & 21, diagram 1) to monitor network .pressure, electric switch (20,:diagram I) to shut off water-supply when signalled by the electronic control panel (1, diagram. 2), communication bridge (6 & 9,. diagram 1) to allow the piston to reciprocate (10, diagram 1) using trapped water and return to its initial position, deactivating the -switch (11, diagram 1) and stopping the timer (2, diagram 1). connection couplings (7 & 8, diagram 1) for connecting and disconnecting the water chamber (18 , diagram 1), reciprocating piston (10, diagram 1) equipped with a: cortical rubber seal ("O-ring”) (14, diagram 1), bypass switch (1.5, diagram 1) to override the water leakage control mechanism when necessary.
[0010] Diagram 2 highlights the operational commands of the water leakage control mechanism, initiated by the. switch (1 1, diagram .1).. This switch triggers the timer (2, diagram 2), which, after the preset tolerance tinie, signals the electric- panel switch. (20, diagram 1) to shut off. Diagram 2 also includes: electronic control panel (1, diagram 2) that displays notifications regarding water leakage in the plumbing, system, emergency switch (3, diagram 2) for immediate use in urgent situations, adjustable tolerance timer (2, diagram 2) that is configurable from 0 to 20 minutes, allowing differentiation between. normal water flow and leakage- and ff the duration exceeds the set time, the timer signals the electric switch (20, diagram 1) to close, on-off switch (4, diagram 2) for complete deactivation of the water leakage control, mechanism, air vent (23, diagram. 1) that; ensures the release of a.tr from the chamber, to prevent, air pressure build-up m the hydro- chamber,
[0011] With the leakage control system, the User sets a predetermined time to distinguish between desired, water flow and continuous leaks, whether small or large, which could cause varying degrees of damage to the home.
[0012] The system can shut off the water supply even with a single drop of leakage.
Claims
CLAIMSThe water leakage control mechanism operates through precise, monitoring of water flow in the hydro-chamber (.18, diagram 1). When there is. any water flow, whether small or large, the piston (10, diagram 1) rnoves due to network decompression and supply pressure (1, diagram 1) and this reciprocating. motion triggers the switch. (11, diagram 1 ), allowing water to pass through the supply holes into the network. Once the desired flow stops, the return spring helps the piston (10,diagram 1) return to its initial position, dosing the supply holes to the -network and deactivating the command switch (1.1, diagram 1) and any remaining water flows through the communication bridge (6 & 9, diagram 1) to the rear of the hydro-chamber. it includes an air vent (23, diagram 1) between the communication bridge (6, diagram 1 ) and the hydro-chamber (9, diagram 1) to eliminate air compression within the hydro-chamber (18, diagram 1).The electronic panel (1, diagram 2) incorporates.: flow timer (2, diagram 2) that is adjustable, based on. the chosen duration, which signals the water electric switch (20, diagram 1) to close after the set time, main on-off switch (4, diagram 2) for complete deactivation of the water leakage control mechanism.It also includes: emergency command switch. (3 , diagram 2), allowing- the mechanism to bypass standard operations and provide, immediate water supply during emergencies.
