Device for generating large volumes of smoke

Abstract

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

AI Technical Summary

Benefits of technology

The invention is an aerosol device that can generate smoke. It includes a heating chamber with a fuel ignition chamber, a smoke producing solution, a nitrogen propellant, and a valve stem for high-pressure release valves. The device is self-contained, maintenance-free, and can be used with different types of fuel and propellants. It also includes a smoke producing solution pressurized by nitrogen propellant that can be delivered to the heating chamber for vaporization and ignition. The valve stem is made of a stem shaft with a polymer gasket and a plastic bonding adhesive agent. The device can generate smoke in a controlled and safe manner.

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.

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.
