TORCH SYSTEM WITH AUTOMATIC FUEL REPLENISHMENT
20230095561 · 2023-03-30 ·

A system of automatically refueled liquid fuel burning torches includes a central fuel reservoir and a pump interconnected with the torches by a fuel plumbing system. When the fuel reaches a lower level in the torches, the plumbing system is automatically pressurized by the pump so that the fuel flows through the plumbing system to raise the fuel to a higher level in the local torch reservoirs. The refueling can be controlled by level sensors and valves in the torches. A remotely operated wick seal can exclude air from torch interiors and prevent fuel spills. A central controller and/or local torch controllers can be powered by wires and/or by batteries, which can be recharged by solar power. The controllers can be wirelessly monitored and/or controlled by software running on a remote device. The remote device and software can control a plurality of the systems.

READY TO LIGHT FUEL CONTAINER

A fuel container has a fuel reservoir, a flame guard affixed atop the fuel reservoir and providing a wick holder, and a fuel container flange at the connection of the flame guard to the fuel container extending radially outward from the fuel container.

INSECT REPELLENT TORCH CONVERSION KIT ENABLING AUTOMATIC FUEL REPLENISHMENT
20220015350 · 2022-01-20 ·

A kit for converting an insect repelling torch to enable remote refueling while in operation includes a fuel insert sealed at opposite ends to a fuel pipe and to a wick. This fuel insert is installed within the torch with the wick extending upward into the combustion area, and the fuel pipe extending below the torch. The fuel pipe is connected to the automatic refueling system. In embodiments, the fuel insert can be compressed for insertion through a port into the torch and re-expansion within the torch. Or the fuel insert can be rigid, and can replace a removable fuel canister of the torch. Embodiments can convert previously manufactured torches, and/or can be implemented in the manufacture of new torches otherwise based on conventional designs. Embodiments include fuel level sensors, flame ignitors, fuel valves, local controllers, wireless communication with a remote computing device, batteries, and/or solar cells.

TORCH SYSTEM WITH PREDICTIVE CONTROL OF AUTOMATIC FUEL REPLENISHMENT
20240016140 · 2024-01-18 ·

Torches are automatically refilled with a liquid fuel from a central reservoir pumped via a plumbing system, without directly monitoring local torch fuel levels. Instead, each torch includes a passive fuel overfill prevention valve. When refueling, the pump operates until all torches are filled. Refueling can cease after a set time, or when sensors report a backpressure and/or cessation of fuel flow. Pre-calibration establishes torch burning rates and/or maximum refill time. Time between refueling is predicted, based upon total burning time, which can be measured by torch heat sensors or determined according to a usage schedule or direct control of torch ignition and extinguishing by the controller. Reverse pumping can extinguish the torches, and wick ignitors can relight them sequentially. A service provider can monitor fuel consumption, establish a pattern of usage, and supply fuel in time to replenish the central reservoir, and/or other provide maintenance as needed.

FLAME PRODUCING ASSEMBLY REDUCING FUEL EVAPORATION

The present disclosure relates to a flame producing assembly. The flame producing assembly may comprise a fuel reservoir, a flame wick and a fuel wick in fluid communication with the fuel reservoir. The flame producing assembly may further comprise a translation mechanism, wherein the translation mechanism may be configured to switch the fuel wick between a first position and a second position. Further, the flame wick may be in fluid communication with the fuel wick when the fuel wick is in the first position and not in fluid communication with the fuel wick when the fuel wick is in the second position.
