Abstract
The utility model relates to an intelligent water-level automatic detecting device, comprising a water level sensor, a control circuit and a current detecting circuit; the control circuit is connected with the water level sensor and is used for starting a water pump when the detected water level is higher than a lower limit position; and the current detecting circuit is connected with the control circuit and is used for cutting off the power supply when the water pump is no-load. The specific work process is as follows: when the detected water level is higher than the preset lower limit position, the control circuit starts the water pump to work; along with the droplowering of the water level, only when the water pump is detected to be no-load, the control circuit controls the water pump to halt instantly or after setting for a prolonging time according to needs, namely the water is pumped to be lower than blades of the water pump, thus achieving the aim of discharging residual water to the lowest water level.
