FIG. 1. is a perspective view of a hand-held steam generator 1; there are one liquid reservoir knob 121 and one steam adjustment knob 112 deposed on the shell of the hand-held steam generator 1. The steam adjustment knob 112 could also regulate the flow rate of steam jetting from the steam generator 1, wherein the steam rate is 24-45.0±5 CC/min. The hand-held steam generator 1 can be used alone.
FIG. 2 is a schematic view of a hand-held steam generator of the first embodiment according to the invention. The hand-held steam generator 1 further comprises a handle grip 11, a liquid reservoir 12, a bottom casing 13, a PCB main board 14, a water pump 15, a heating element 17, a temperature control device 18, silica gel tubes 16 and a inner nozzle 19. The vapor adjustment knob 112 and the switch button 111 is settled on the handle grip 11. The liquid reservoir knob 121 is deposed on the liquid reservoir 12. After adding water to the liquid reservoir 12, an actuation mechanism regulates the potentiometer 141 of the PCB main board 14, controls the amount from the water pump 15, dispenses water into the heating element 17, and produces the steam instantaneously; the vaporized water is jetted out from the inner nozzle 19, and adjustment knob 112 is used to modulate to control the steam-jetting amount.
Selectively, the hand-held generator 1 can mount a pole 2 or cleaning tools 5 on its top end or on its bottom end. The cleaning tools 5 could be jetting nozzles, a circular brush, a triangular brush, a glass scraper, and an implanted brush. By regulating the amount of produced steam jetted out from the inner nozzle of the hand-held steam generator, users can utilize the cleaning device more easily and effortlessly for any environment conditions or demands, such as the small amount dry steam is good for to clean wooden floor.
