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.

Description

FIELD OF THE UTILITYThe present utility relates to a water-supply assembly in the steamer device.BACKGROUND OF THE UTILITYThe sectional structure of a conventional boiler of garment steamer is showed in FIG. 1: an inner water box 2 is installed in the inner space 11 of the housing 1. The bottom of inner water box 2 is installed with an electric heating plate 3. The side wall of the inner water box 2 has a water inlet 21 close to the bottom of the inner water box 2, a steam pipe 22 is disposed on the top of the inner water box 2; said steam pipe 22 goes through the housing 1 and is leaded outside. The rear side of the housing 1 has groove 12 much higher than the electric heating plate 3 of the bottom of the inner water box 2, the bottom of said groove has a through hole 13; the lower surface of the bottom of said groove 12 has a circular lower flange 18 extending downward and surrounding the through hole 13. A sink 5 with an upward opening is fixed on said lower flange 18. The bottom...

AI Technical Summary

Benefits of technology

The object of the present utility is to provide a water-supply mechanism of boiler in the garment steamer, which is adaptable in an open outer water box, and the manufacture cost is relatively lower.

The water mechanism of the boiler in the garment steamer of the present invention, it discloses a check valve on the bottom of the groove of the housing, the outer periphery of said check valve has a flange; so when the outer water box is put in the groove of the housing, said check valve will push the plug on the water outlet of the outer water box open, the water in the outer water box will flow into the inner water box smoothly. When the outer water box departs from the groove of the housing of the boiler, the water in the outer water box will be blocked by its plug and will not leak; and the water in the inner water box is blocked by the flange of the outer periphery of said check valve and will not outflow. The inside of the valve body of the check valve only has a guiding rod, a spring and a plug, the structure is simple, the manufacture cost is low, further the operation is flexible and reliable. The guiding rod will guide the spring, so the lower portion of the spring will be prevented from displacing and the breakdown caused by the inclining is avoided; and it is convenient for installing the spring in the assembly process. The guiding rod is applied to restrict the spring, so the upper portion of the spring will be prevented from displacing and the breakdown caused by the inclining is avoided; and it is convenient for installing the spring in the assembly process. A sealing ring with an introversive upper end is disposed between the check valve and the lower flange of the bottom of the groove, the protective pipe on the water outlet of the outer water box will be closed from its outer periphery. The water in the outer water box will be effectively prevented from leaking from the outer periphery of the protective pipe; besides, when the outer water box departs from the groove of the housing, the underneath of the introversive edge of said sealing ring will cooperate with the outer flange of the check valve, the sealing effect is better compared to the structure wherein the outer flange of the check valve straightly closes the through hole of the groove in the housing.

Problems solved by technology

However, the water addition in this kind of outer water box 6 will be restricted by the plug 62, the speed of water addition is slower, if there is no specialized device, it will be difficult to add water.

Further, this kind of the outer water box 6 is difficult to be cleaned.

However, it needs additional water pump and corresponding control circuit in this kind of water-supply mechanism, so the manufacture cost will be increased, the consumption of the electric energy will be increased, too.
