A plug is attachable to a wall of a torch that is configured to burn a liquid fuel. The plug adds one or more features to the torch, such as a fuel level sensor, a temperature sensor, a tilt sensor, an automatic wick ignitor and/or extinguisher, a wick clamp, a wick advancing mechanism, and/or a global positioning system. The plug includes an electronic controller, and wired and/or wireless electronics configured to provide remote control and/or monitoring of the added features. Power for the plug can be provided by a battery and/or a solar panel. The controller can establish a unique torch identity, thereby enabling a remote computing device to monitor and/or control features of a plurality of torches that each have a plug of the present disclosure attached thereto. The plug can be removably or permanently attached to the torch.

A liquid fuel burning torch system maintains fuel within one or more torches by pumping fuel from a central reservoir to the torches via a plumbing system. The torches can be extinguished by reversing the flow of the fuel in the plumbing system, for example by reversing a pumping direction of the pump, switching pumps, or actuating flow reversal valves. The torches can include remotely controlled torch igniting mechanisms, wireless access for remote torch monitoring and/or control, and/or heat sensors for determining whether the torch is burning. The torches can include fuel overfill prevention (FOP) valves. A flow of fuel through the FOP valves can be directed so as to avoid impinging on plugs of the FOP valves. The FOP valves can include check valves that allow fuel to be drained from the torches even when the FOP valves are closed.

A system for repelling insects from an outdoor area includes at least one torch configured to disburse an insect repellant by burning a fuel, and a central fuel reservoir interconnected with the torches by a fuel plumbing system and configured to automatically replenish the fuel in a local reservoir of the torch. Fuel can be gravitationally transferred from the central reservoir to the torches, or maintained under pressure in the plumbing system and 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.

A torch refilling assembly includes a funnel for receiving a liquid fuel. A spout is fluidly coupled to the funnel and the spout is positioned in an opening of a fuel canister of a torch to direct the liquid fuel into the fuel canister of the torch. A rest is coupled to and extends laterally away from the funnel for engage a lid of the fuel canister for storage when the fuel canister is filled with the liquid fuel. A valve is movably coupled between the funnel and the spout. The valve is selectively positioned in a closed position to inhibit the liquid fuel from flowing out of the funnel. The valve is selectively positioned in an open position to pass the liquid fuel therethrough thereby facilitating the fuel canister to be filled with the liquid fuel.

A hanukiah that includes a base, eight oil holders and a ninth one that serve as a shamash. Each of the oil holders is shaped as a hollow cup that has a top opening and a narrower hollow leg that includes two opposite horizontal holes. The oil holders are designed to receive oil for lighting a wick. The base includes nine vertical holes which are designed to receive the narrow hollow legs in a way that enables them to rotate inside. The vertical holes are connected together by a horizontal pipe. The user may pour oil into the shamash oil holder and by that to fill the other oil holders. The user may turn one of said oil holders to determine how many of them will be filled by oil.

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.

A system and method for refilling a liquid fuel candle includes a refillable container and a refilling station with a reservoir of liquid fuel and a designated region for receiving the refillable container. A user control activates a pump causing fuel to flow from the reservoir and into the container until a predetermined fill level is reached, at which time the pump is deactivated. In one configuration the bottom of the container includes a port that cooperates with a post on the refilling station causing the candle to fill from the bottom up. The refilling station may further include an input for receiving a colorant or a scent that is added to the fuel as it flows from the reservoir to the container. The refilling station may include a plurality of designated regions for receiving a plurality of containers to be refilled, including simultaneous refilling.
