Abstract: A gas burner includes a burner seat having therein a path for provision of gas, a burner core rested on an inner periphery defining the path and having multiple slits defined through opposite sides of the burner core and a burner cap placed on top of the burner seat to sandwich the burner core. The slits are defined in such a manner that an air flow inside the burner core is rotated and directed upward relative to the burner core.

Abstract: A gas burner includes a cylindrical hollow body, a top casing integrally mounted on top of the body and having multiple through holes defined in two opposed side faces of the top casing to communicate with an interior of the body and a supporting baffle formed inside the top casing to engage with a bottom face and a top face of the top casing so as to increase rigidity of the top casing so that distortion of the top casing is avoided.

Abstract: A gas burner includes a supporting disk and a hollow disk supported by the supporting disk and having multiple holes. The holes are inclined relative to a surface so that burning effect of the gas burner is maximized.

Abstract: A portable burner has a base with an electrical lighter and a nozzle provided with an inlet and multiple outlets, a gas pipe retrievable received in the base and having a removable connector adapted to connect to a gas source, a support snugly located on top of the base to encase the electrical lighter in the base and having at least three ledges and at least three bosses oppositely formed in relation to the ledges and a cover encasing the support and the gas pipe in the base and having at least two protrusions formed to correspond to at least two keyholes in the bottom face of the base.
