GAS COMBUSTOR

摘要

The present invention provides a gas combustor which includes a gas container having a discharging nozzle, a fuel gas controlling device, and a piston disposed between the gas container and the fuel gas controlling device and capable of being reciprocally moved; through the pressure applied by a second spring provided in the fuel gas controlling device to the piston being greater than the pressure of a first spring and the fuel gas in the discharging nozzle and the pressure applied by the second spring to the piston being smaller than the pressure for vaporizing fuel in a vaporization chamber, the piston is enabled to be reciprocally and axially moved for opening or closing the discharging nozzle, thus the liquid gas can be effectively and fully vaporized and the combustion efficiency can be greatly enhanced.

1. A gas combustor, including:
a gas container, the bottom end thereof being provided with a filling nozzle and the top end thereof being formed with a connection part, and said connection part being axially connected to a discharging nozzle, said discharging nozzle including a valve seat having the top end being axially formed with a valve hole, and the interior of said valve seat being provided with a valve pin capable of protruding out of said valve hole for opening or closing said valve hole, and a first spring enabling said valve pin to be axially and elastically retractable; a fuel gas controlling device, the bottom end thereof being formed with an accommodation chamber, the inner periphery of said accommodation chamber being formed with an engage part connected to said connection part, the top end of said accommodation chamber being axially formed with a sleeve hole, and the top end of said sleeve hole being axially connected to a fuel gas channel, the downstream end of said fuel gas channel being provided with a gas ejecting nozzle; wherein, said fuel gas channel being communicated with a rod hole, and said rod hole being further connected to a control rod capable of opening or closing said fuel gas channel; and a piston, including a piston disc sleeved in said accommodation chamber, the top surface of said piston disc being axially protruded with a sleeve column sleeved in said sleeve hole, and said piston disc and said sleeve column being axially formed with a penetrated hole allowing fuel gas to pass, wherein the bottom end of said piston and the top surface of said connection part being formed with a vaporization chamber, and a second spring being disposed between said piston disc and said accommodation chamber; through the pressure applied by said second spring to said piston being greater than the pressure of said first spring and said fuel gas in said discharging nozzle and the pressure applied by said second spring to said piston being smaller than the pressure for vaporizing fuel in said vaporization chamber, said piston being enabled to be reciprocally and axially moved for opening or closing said discharging nozzle.
