Abstract
A convertible burner for gas-fueled cigarette pocket lighters for use with flint and wheel ignition, the burner including a burner body having a central gas fuel passageway and an air inlet channel in fluid communication with the central passageway and may have a plurality of integrally formed passageways around the periphery of the burner body. An air control structure in the form of a collar is movable to a first position with respect to the burner body to close the air inlet channel and form a post-mix burner for flint and wheel ignition, and to a second position with respect to the burner body to admit air via the air inlet channel to form a pre-mix burner after ignition. The relative movement can be longitudinal or peripheral, and the peripheral movement can be circumferential. In one embodiment, the collar surrounds and is immediately adjacent to the air inlet channel.

15. A method of igniting a single burner of a lighter in a post-mix configuration and thereafter transforming the burner to a pre-mix configuration, the method comprising the steps of:
-
a. providing a burner having a passageway therethrough and an air inlet in fluid communication with the passageway; b. providing an air control structure surrounding at least a part of the burner having the air inlet therein; c. positioning the burner and air control structure to a first relative position wherein the air control structure substantially blocks air from entering the air inlet such that the burner and air control structure form a post-mix configuration wherein fuel passing through the passageway is not mixed with air until after the fuel exits the burner; d. igniting fuel exiting the burner with an ignition system while the burner and air control structure are in the first relative position, the ignition system activated by a user'"'"'s digit; and e. thereafter positioning the burner and air control structure to a second relative position by activating an actuating mechanism positioned adjacent to the ignition system using subsequent motion of the same digit, wherein the air control structure permits air to enter the air inlet and mix with fuel passing through the passageway such that the burner and air control structure form a pre-mix configuration wherein fuel passing through the passageway is mixed with air before exiting the burner. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of igniting a single burner of a lighter using a flint and wheel with the burner in a post-mix configuration and subsequently operating the burner in a pre-mix configuration wherein a flame is projected from the lighter in both the post-mix and pre-mix configurations, the method comprising the steps of:
-
a. providing a burner body assembly having a burner body and housing, the assembly having a primary passageway therethrough; b. providing a collar surrounding at least a part of the burner body assembly; c. causing a first relative position between the collar and the burner body assembly wherein the collar substantially blocks air from entering the primary passageway such that the burner body assembly and collar form a post-mix configuration wherein fuel passing through the primary passageway is not mixed with air until after the fuel exits the burner body; d. rotating a wheel of a flint and wheel igniter to ignite the fuel exiting the burner to create a post-mix flame above the burner; and e. subsequently causing a second relative position between the collar and the burner body assembly by travel of the actuation mechanism wherein the collar in the second relative position permits air to enter the primary passageway such that the burner body assembly and collar form a pre-mix configuration wherein fuel passing through the primary passageway is mixed with air before exiting the burner body, converting the post-mix configuration to the pre-mix configuration. - View Dependent Claims (23, 24, 25, 26, 27)
