Steam output control structure for steam cleaner

Abstract

A steam output control structure includes a hose extended from the housing of a steam cleaner and having a grip at the end, a control valve mounted in the grip for output f steam, a heat-resisting high-tension tube connected between the control valve and the steam output port of the steam cleaner, the control valve having a spout for steam output and a valve rod supported on a spring member and adapted to close the steam passage between the spout and the heat-resisting high-tension tube, and a control knob pivoted to the grip and adapted to open the valve rod for letting steam pass from the heat-resisting high-tension tube to the spout.

What the invention claimed is:  
     
         1 . A steam output control structure installed in a steam cleaner having a steam chamber and a steam outlet pipe for output of steam and adapted to control the output of steam from the steam cleaner, comprising a hose extended from a front side of the housing of the steam cleaner, a grip fixedly fastened to one end of said hose remote from the housing of the steam cleaner, a control valve mounted in said grip, a heat-resisting high-tension tube connected between said control valve and the steam outlet pipe of the steam cleaner and adapted to guide steam from the steam outlet pipe of the steam cleaner to said control valve for application, said control valve comprising a spout at a front side thereof, a steam inlet pipe disposed at a rear side thereof and connected to one end of said heat-resisting high-tension tube, a valve hole extended to a bottom side thereof and disposed in fluid communication with said spout and said steam inlet pipe, a valve rod mounted in said valve hole and moved between a first position where said valve rod closes the passage between said spout and said steam inlet pipe and a second position where said valve rod opens the passage between said spout and said steam inlet pipe, and a spring member mounted in said valve hole to hold said valve rod in said first position, and a control knob pivoted to said grip and stopped at one end of said valve rod outside said valve hole and adapted to move said valve rod to said second position against said spring member.
