Title:
IMPROVED AUTOMATIC PLANT WATERING SYSTEM AND WATER LEVEL CONTROL
Document Type and Number:
WIPO Patent Application WO2000025572
Kind Code:
A9
Abstract:
The two level liquid level control device includes an outer cover (1) to which is attached a central stand (2). The central stand (2) has a pivot point (14) around which the float (4) pivots up and down with the water level in the control device. When the incoming water through inlet (5) raises the water level to a preset level the actuator arm (6) is switched in a clockwise direction causing it to press the toggle (7) into a straight position so that a resilient stopper (8) is pressed against the water entry point spigot (9) to stop the flow. As the water level is lowered and reaches a preset lower point the actuator arm is switched in an anti clockwise direction to pull up the center of the toggle device (7) so that the stopper (8) is removed from the water entry point (9) to allow water to flow in.
