Abstract:
A water level controller for a hydroponic system includes a float shifting upward and downward with the culture solution, a first magnetic attraction element and an inlet valve for feeding in the culture solution. The float includes a seal and a second magnetic attraction element. The seal closes the inlet valve to stop feeding in water when the float ascends to a high water level, and moves way from the inlet valve to start feeding in water at a low water level. The second magnetic attraction element attracts the first magnetic attraction element to keep the seal closing the inlet valve at the high water level and to keep the seal moving away from the inlet valve at the low water level, until the buoyancy of the float is larger than the magnetic attraction between the second and the first magnetic attraction element thereby causing escape from each other.

Claim (Index 1):
A water level controller for a hydroponic system, comprising a hollow casing which is fixed in a hydroponic cultivation tank and a float which is pivoted in the casing to ascend and descend with the water level of the culture solution, wherein a bottom of the casing is connected with a hydroponic cultivation tank, a top of the casing is connected with atmosphere, and the casing is provided with an inlet valve and a first magnetic attraction element, wherein the inlet valve is provided with a water inlet end for feeding in the culture solution from outside and an inlet nozzle which is transfixed into the casing, allowing the outer culture solution to enter the hydroponic cultivation tank through the inlet valve to raise the water level; a side of the float being pivoted in the casing, so that the other side of the float shifts upward and downward with the culture solution against the pivot point, and the float being also provided with a second magnetic attraction element and a seal which shift with the float simultaneously; the seal being disposed on a location corresponding to the inlet nozzle of the inlet valve to abut at and close the inlet nozzle of the inlet valve, when the water level in the hydroponic cultivation tank ascends to a high water level, whereas, move away from the inlet valve when the water level descends to a low water level; the second magnetic attraction element being disposed on the float at a location corresponding to the first magnetic attraction element, and shifting with the float simultaneously to approach and attract the first magnetic attraction element to keep the seal closing the inlet valve when the high water level is reached, until the water level in the hydroponic cultivation tank descends to the low water level that the gravity of the float is larger than the magnetic attraction between the second magnetic attraction element and the first magnetic attraction element, enabling the second magnetic attraction element to escape from the first magnetic attraction element.
