This utility model discloses a spray device for planar quenching equipment, belonging to the technical field of local quenching equipment. It includes a support, a thermoelectric battery, and an electric fan. The upper end of the support is connected to a speed-increasing air duct, while a quenching nozzle is movably inserted into the lower end of the support. The quenching nozzle is connected to an adjusting base and can spray coolant through the nozzle to quench the surface of the planar workpiece. A thermoelectric battery is arranged outside the speed-increasing air duct, connected to an induction controller circuit. The induction controller is connected to the electric fan and a push-pull electromagnet, controlling the electric fan and the electromagnet to turn on or off. In use, the induction controller can simultaneously detect the surface temperature of the workpiece and the voltage of the thermoelectric battery. When the electric fan starts, air-cooled quenching occurs; when the temperature drops below a threshold, the push-pull electromagnet is activated, and water-cooled quenching occurs through the quenching nozzle. This optimizes the cooling method and suppresses deformation and cracks that occur during the quenching process.
