Embodiments of the present disclosure provide a smart water dispenser and a control method thereof. The smart water dispenser includes: a mechanical switch, an electronic switch and a controller. The controller is configured to determine whether water usage is normal according to ON/OFF states of the mechanical and the electronic switches; if so, to indicate a water discharged volume detection unit to collect a water discharged volume; and otherwise, to turn off the electronic switch and transmit a play instruction to a voice playback unit. The control method includes: detecting states of the mechanical switch and the electronic switch in real time; determining whether the mechanical switch is in the ON state when the electronic switch is switched from the OFF state to the ON state; if so, turning off the electronic switch and outputting a prompt voice; and otherwise, collecting the water discharged volume when the mechanical switch is switched from the OFF state to the ON state.
