Device Adapted to Withdraw Gas and to Control Gas Flow Rate Discharged Therefrom

A device adapted to withdraw gas and to control the gas flow rate discharged therefrom comprising:

• a filling valve initially in a shut position and adapted to be engaged to move to an open position for filling liquid gas;
• and
• a sleeve having a hollow shape and including an open end engaged with the filling valve, and a peripheral wall including a fluid passing zone that enables liquid gas outside the sleeve to flow inside;
• an absorbing member having an ability to absorb liquid gas disposed in the sleeve;
• and
• a gas control unit including a main body, a gas inlet and flow rate adjusting mechanism, and a gas outlet mechanism, with the main body including one end receiving the gas inlet and flow rate adjusting mechanism and another end receiving the gas outlet mechanism respectively, with the gas inlet and flow rate adjusting mechanism including an adjustably movable valve and a first air seal, with the first air seal mounted between the adjustably movable valve and the main body to prevent liquid gas from passing therebetween, with the gas inlet and flow rate adjusting mechanism including the adjustably movable valve including an end engaged with the sleeve and the absorbing member such that after the absorbing member absorbing liquid gas outside the sleeve through the fluid passing section, vaporized gas emitted from the absorbing member is able to flow into the adjustably movable valve, with the adjustably movable valve in fluid communication with the gas outlet mechanism such that vaporized gas is discharged from the device from the gas outlet mechanism.
