Abstract: A balanced high efficiency outdoor heater is provided to increase the heat radiation area, and to improve the stability of the structure. The heater includes a burner provided at an upper end of a standing column, a bottom base provided at a lower end of the standing column, and a beam is set between the burner and the standing column. The beam and the standing column are connected by pipe fittings. An ignition control device is equipped inside the base and is connected to the burner. An electrode rod and a thermocoupler are connected to the ignition control device under the burner. A first reflector is fixedly connected to the lower end of the burner and a gas valve is equipped in the bottom base. Compared with the prior art, the burner uses sintered felt and a heating surface of the burner faces upside down to improve thermal efficiency.

Abstract: The present invention provides a gas combustor having detachable combustion device, which includes: a housing having the interior installed with a base, and a combustion device. When the combustion device is inserted in an insertion slot of the housing, the upstream end of a mix pipe of the combustion device is airtightly inserted in a sleeve opening of the base, and a pair of locking sheets of the combustion device are moved along a pair of stopping protrusions of the housing and cross the pair of stopping protrusions, so a first spring between a lock button and a positioning seat of the combustion device is allowed to respectively be compressed for storing energy or stretched for releasing energy, and the pair of locking sheets are enabled to be abutted against inner edges of the pair of stopping protrusions, so an interference is generated for forming a locking and combining status.

Abstract: A gas burner includes a gas reservoir, a combustion device, and a tilt safety device fluidly connecting to one another. The tilt safety device includes first and second seats including first and second gas passages respectively, an elastomer disposed on the second seat and including a section defining a stop, a control mechanism including a lever adjacent to the elastomer and including a first contact area and at least one second contact area selectively engaging with a pusher which engages with the stop, and a gas flow channel connecting to the second gas passage and a hole extending through the elastomer and the first gas passage and including the first and second ends thereof including the stop disposed therebetween. The first and at least one second contact areas space from the elastomer at first and second heights respectively. The second height is less than the first height.
