Wei-Ming TSAI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10605452
    Abstract: A gas combustor comprises a gas container, a fuel gas controlling device, a housing, a piezoelectric device and a combustion device. The safety switch is slidably disposed in an opening of the housing and includes a slide member, a fasten member and a passive member, adjacent surfaces of the slide member and the fasten member are disposed with a connecting mechanism and a radial sliding mechanism, thereby enabling the slide member to perform a radial sliding motion towards the left or the right at the front end of the fasten member; a rear surface of the passive member is formed with a lock tenon abutted against a block tenon of the fuel gas controlling device, thereby forming a lucked status; when the slide member is pulled towards the left or the right, the lock tenon is released from the block tenon, thereby forming an unlocked status.

  • Patent number: 9879856
    Abstract: 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.

  • Patent number: 9464760
    Abstract: A gas filling nozzle with safety function includes a valve seat, a first thimble, a safety valve, an inner sleeve and a first spring; the first thimble is sleeved in the valve seat, the safety valve is disposed at the top of the first thimble, and the inner sleeve is combined at the top of the valve seat, thereby allowing the first spring to be disposed between the inner sleeve and the safety valve. So when the gas filling nozzle is subject to a high temperature environment, the high-pressure gaseous/liquid mixture inside a gas container is able to be discharged to the exterior through the safety valve, thereby preventing the gas container from exploding.

  • Patent number: 9435486
    Abstract: The present invention relates to a hand-held refillable gas container, which includes a metal can body for storing liquid gas, and the top and the bottom of the can body are respectively installed with a gas discharge part and a filling nozzle; wherein the gas discharge part includes a connection ring and a discharge nozzle disposed in the connection ring; and the filling nozzle is able to be connected to a discharge nozzle of a conventional canned gas, thereby allowing liquid gas to be filled and stored in the can body. Accordingly, the gas container provided by the present invention has advantages of allowing a user to easily hold and carry around for satisfying different combustion requirements and various operation environments.
