The present invention relates to a liquid sprayer comprising a liquid container, a fan case, a fan motor, a nozzle, a liquid transport pipe, and a pressure pipe. The liquid container stores liquid to be sprayed. The fan case is provided, on one side thereof, with suction holes through which air flows in, and on the other side thereof, with discharge holes through which compressed air is discharged and a pressure hole through which a part of the pressurized air is sent to the liquid container so as to pressurize the liquid. The fan motor, disposed inside the fan case, raises the pressure by sucking in air through the suction holes, and discharges the air through the discharge and pressure holes. The nozzle, coupled to the discharge holes, sprays the pressurized air, and can comprise a plurality of spray nozzles. The liquid transfer pipe transports the liquid from the liquid container to the interior of the spray nozzle. The pressure pipe, connected from the pressure hole to the interior of the liquid container, raises the discharge power of the liquid due to pressurized air. In addition, a plurality of liquid containers are provided, and the liquid transport pipe is provided with a liquid control valve for controlling the discharge of the liquid. According to the liquid sprayer characterized by such features, the liquid can be sprayed to far distances from the increased spraying power of the liquid even without an addition of a separate fan, liquids of different types can be selectively sprayed easily, and the liquid in each liquid container can be easily sprayed separately using one fan motor. Furthermore, the present invention facilitates spraying the liquid over a wide area due to the simple nozzle construction, and has the benefit of preventing deformation of the liquid container and damage to the connecting parts by reducing the pressure applied to the liquid container in case of nozzle blockage or low rate of nozzle discharge.Linvention concerne un vaporisateur
