Radiant heat lifting device for outdoor flame heater

A radiant heat lifting device for outdoor flame heater, comprising:

• a housing defining an inside space for installing a gas barrel;
• a base mounted on the housing and having a burner therein and a flame outlet at a top thereof;
• a plurality of support members disposed on the housing and having a bottom end arranged at a periphery of the flame outlet;
• a frame body arranged at a top of the plurality of support members, a mounted space being formed between the support members;
• a glass tube having a lower opening at a first end thereof mounted on the flame outlet for positioning the glass tube in the mounted space between the support members;
• a heat-resistant net tube made of high-temperature resistant material and mounted to extend longitudinally upward from an upper opening of the glass tube;
• the heat-resistant net tube including an intermediate portion having a plurality of mesh openings formed therethrough, the heat-resistant net tube having a top end sealed and a bottom outlet connected to the upper opening of the glass tube;
• and
• a cover arranged on the heat-resistant net tube to be longitudinally displaced from the intermediate portion thereof, the cover including a multitude of circulation holes at a periphery thereof;
• whereby a flame emitted from the flame outlet along the glass tube heats the heat-resistant net tube to thereby increase the thermal radiation of the glass tube;
• and an exhaust in the glass tube flows out through the mesh openings of the heat-resistant net tube to be discharged through the circulation holes of the cover.
