Device for generating large volumes of smoke

Abstract

The present invention relates to a hand held device for continuously producing large volumes of smoke from a smoke producing solution. The design allows for repeated, fast, and lengthy heating of the heating chamber, for use of a duel heating system using a fuel and a heating element wrapped fuel coil for producing continuous use, and thus is an improvement over prior devices which can only be utilized in short bursts.

AI Technical Summary

Benefits of technology

This patent describes a device that can continuously fire and vaporize a smoke solution. By venting the ignition chamber and using a spark capture tube, ignition is ensured on the first try. The device is self-contained and maintenance-free, and can be used with external nitrogen propellant or fuel. Additionally, the device includes a high-pressured chemical spray cannon. The stainless steel coil allows for continuous firing, and the vaporization of the smoke solution is improved by using a second heater wrapped around the coil. The technical effects of this device include improved efficiency, reliability, and reduced downtime between bursts.

Problems solved by technology

Because the vaporization of the smoke producing liquid drains heat energy from the heat source, the problem that exists with these devices is that they can only be used for relatively short bursts since heating the liquid also cools the heat source.

This is especially true with battery operated heat sources, and even gas fired heat sources have limited capacity to heat before cooling after a smoke burst.

In addition, smoke generators typically have limited operational capacity for smoke producing liquid prior to replacing the source or refilling them with additional fluid.

The device has limited capacity for gas generating liquid and is only operable for short bursts before cooling below the vaporization temperature of smoke producing liquids, since the heat chamber cools very quickly.

In addition, the device cannot generate a dense, thick cloud of smoke as is necessary for many industrial uses.

A further problem with this, and other devices where an ignition spark ignites a gas, is that ignition is very haphazard and igniting the gas can take several tries, leading to a dangerous explosive situation if too much gas accumulates in the ignition chamber before the gases ignite.

One problem of particular note, that has been a weakness for decades for smoke machines, is that the vaporization of the smoke solution and heating the ignition chamber is accomplished by the same propane source.
