The patent US12044403B2 describes a torch designed with a unique body structure that includes two angled portions, a control knob, and a trigger mechanism. The body features a top surface, bottom surface, and sides, with the first and second portions having adjacent top and bottom surfaces. The control knob is positioned on the second portion for adjusting fuel flow, while the trigger, located on the first portion, can be moved from an off to an on position to activate an igniter. The trigger incorporates a deflectable tab that locks it in the on position by engaging a ledge in the body. Additionally, the torch includes a pivot arm and a seesaw mechanism that work together to control the flow of fuel through a burn tube extending from the second portion.

Further claims detail the torch's functionality, including a first and second valve assembly that manage fuel flow, allowing for flame length adjustment without extinguishing the flame. The design also features a nozzle and flame guide within the burn tube, with specific dimensions for the orifice to optimize fuel and air mixing. The torch's trigger mechanism is enhanced with projections that guide its movement within channels in the body, ensuring smooth operation. The patent outlines various configurations and components, such as a ceramic flame holder and a sleeve for surrounding a conduit, emphasizing the torch's innovative design aimed at improving user experience and functionality.
