[0002] Sprayer is the abbreviation of spray equipment. Sprayer is a device that uses air suction to turn medicine or other liquids into mist and sprays it evenly onto other objects. It is composed of a compressed air device and a thin tube, a nozzle, etc. In order to meet the needs of use, small push-type sprayers have now appeared.

[0003] Before demolding the mold, it is necessary to spray a release agent on the surface of the mold to help the workpiece to separate from the molding. Release agents with different magnifications are suitable for molds with different molding rates. Therefore, when spraying different molds, different nozzles need to be prepared to use high-magnification and low-magnification release agents respectively. This process increases the complexity of the operation and is inconvenient to assemble and use release agents with different magnifications. In view of this, we propose a new dual-liquid nozzle.
