A portable heating device is provided that generally consists of an upper housing having a plurality of openings that allow heat to escape from a coiled infrared heating tube that generates radiant heat. The portable heating device also includes an upper surface with an opening that produces a visible flame and conductive heat. The upper surface is also associated with a flame burner that feeds a cooking surface.

A cooking grate assembly configured for use on a portable radiant heater with a front safety grille. The cooking grate assembly has a flat main cooking grate with an upper/inner end and a lower/outer end, a pair of spaced hook tabs extending from the upper/inner end of the grate that attach to an upper part of the grille, and a pair of inwardly-angled key tabs extending from the lower/outer end of the grate. A pair of detachable legs supports the grate from a lower part of the grille, with a rotatable locking connection to the key tabs on the grate at one end and opposed inner and outer hooks at the other end that both support the grate on the grille and provide a nesting flat interlock to the rear face of the grate for storage.

The embodiments herein provide a smart patio heater device comprising a base having vertically extending chamber for receiving a gas from tank to supply gas to a gas burning area for generating heat which is dissipated in all directions or to a user desired area. The thermoelectric generators (TEG) are affixed over the burning area for generating electric power from the heat. The generated power is provided to a central processing system and stored in the batteries for later use. A water pipe connected between a water storage unit and TEG unit at is encircled around chamber and passed through the post. The water is circulated within the water pipe to absorb the excess heat generated around the TEG unit to prevent overheating. The electronic devices are provided to derive electrical power from the batteries for providing additional functions to the user.

A stove core structure of an infrared gas stove is provided, including a bottom cover having a receiving groove, a bottom portion of the receiving groove having a gas through hole for guiding gas into the receiving groove, a guiding plate received in the receiving groove, being elevated, the bottom portion and the guiding plate having a space therebetween, a gap which is arranged around a circumferential side of the guiding plate and for the gas to pass therethrough serves as a main gas flow line. The gas flows through the circumferential and out from the infrared ceramic piece assembled on an opening of the receiving groove so that the gas contacts the air around the infrared ceramic piece fully and is combusted completely so as to prevent monoxide poisoning and waste of gas and to elevate a thermal efficiency.

A radiant area heater includes a columnar base with a hollow compartment and a heating column disposed on the columnar base. The heating column includes a control portion with at least one controller, a burner, and a sparker and a flame portion that includes a combustion chamber. The combustion chamber is disposed on a cylindrical member that has at least one vent allowing air to circulate to the burner and within the combustion chamber. The heating column further includes at least one heat emitting screen disposed above the flame portion that radiates heat outwards from the heater. A cover is disposed over the heating column to direct heat outwards and away from the heater.

The invention relates to heating equipment. An umbrella-shaped heater comprises a base component, a support pipe and a burner component, the base component comprises a flexible housing, the burner component comprises a top cover located above the burner and used for reflecting the heat of the burner, and a reflecting surface adjusting structure is installed on the top cover for adjusting the angle of the top cover. The invention provides an umbrella-shaped heater with detachable components, thereby greatly reducing the packaging volume and transportation cost and improving the economic effectiveness, and the angle of the top cover can be adjusted to meet the requirements of different users. The invention solves the technical problems in the prior art that an umbrella-shaped heater is of an integral structure, so the packaging volume is large and the transportation cost is high, and moreover, the angle of a top cover cannot be adjusted.

A patio heater, has: a base to be supported on a ground; a stem protruding upwardly away from the base; and a heat generating device secured to the stem, the heat generating device having: a burner fluidly connected to a source of a fuel to be burned; a diffusion sheet enclosing a combustion chamber, the burner located inside the combustion chamber and surrounded by the diffusion sheet; a reflective shield located above the diffusion sheet; and at least one reflective fin mounted to the diffusion sheet and extending away therefrom.

Disclosed are a flameout protection system and a heater. The flameout protection system includes a stove head, a double-needle electrode rod, an electromagnetic valve and a plasma controller. The stove head is provided with an ejection tube and a flame hole. The double-needle electrode rod is connected to the ejection tube, and one end of the double-needle electrode rod is close to the flame hole. The electromagnetic valve is connected to the ejection tube, and the electromagnetic valve is communicated with the flame hole. The plasma controller is electrically connected to the double-needle electrode rod, and the plasma controller is electrically connected to the electromagnetic valve.
