Abstract
The invention discloses a pressurization method and system for a water dispenser. An operational amplifier, a processor, a relay, a water pump motor and a sampling resistor are sequentially connected in series. The in-phase input end of the operational amplifier is connected with the end, close to the water pump motor, of the sampling resistor, the output end of the operational amplifier is connected with the processor, and the reverse input end of the operational amplifier is connected with the ground. The end, away from the water pump motor, of the sampling resistor is connected with the ground. The processor acquires an output current value of the operational amplifier and compares the output current value with a preset current threshold value to determine whether water exists in the water dispenser; if the output current value is larger than the preset current threshold value and it is determined that the water exists in the water dispenser, the relay controls the water pump motor to carry out pressurization. The low-cost operational amplifier replaces a high-cost microswitch, so that the problem that in the prior art, due to the high cost of the microswitch, the cost of the water dispenser is increased is effectively solved.
