Water-supply mechanism in the boiler of garment steamer

Abstract

The water-supply mechanism of the boiler in the garment steamer of the present utility, it relates to a water-supply assembly of a steamer. The rear side of the housing of the boiler has a groove for placing an open outer water box, the bottom of said groove has a through hole for the protective pipe of the outlet of said outer water box going through and a downward extending lower flange surrounds said through hole; a check valve is fixed on the lower flange of the bottom of said groove; a water inlet on the top end of valve body of the check valve straightly faces the through hole of said groove; a water outlet of the bottom of valve body of the check valve communicates with the water inlet of the inner water box; a spring is disposed in the valve body of said check valve, said spring pushes the flange of the outer periphery of the plug in the check valve toward the water inlet of the valve body, and make the protruding portion of the upper end of the plug in said check valve extend into the protective pipe of the water outlet of said outer water box to push the plug of the water outlet of said outer water box. It is convenient for adding water into the outer water box, and the manufacture cost is relatively lower.
