The present disclosure relates to a smoke device. More specifically, the present disclosure relates to a smoke device which has the ability to release different colors of smoke therefrom in a safe manner.
A smoke device may also be known in the art as a smoke grenade or a smoke bomb. A prior art smoke device comprises a container that contains a blend of chemicals. Once the blend of chemicals is ignited, the blend of chemicals burns to produce heat, gas and colored smoke which is forced out of the container and can be seen by onlookers.
Colored smoke has been around for many years and has been used commercially in fireworks, theatrical effects and film. Also, colored smoke has been used for military purposes such as screening or signaling smoke.
As shown in the prior art devices of
Furthermore, in the prior art, there are a variety of ignition methods such as a safety fuse (i.e. lit from an external source), an electric igniter/electric match, friction or strike (i.e. like a match) and pull pin/percussion or fly-off lever (i.e. mainly military) as shown in
The problem with existing designs of the prior art is that during the burning of the blend of chemicals, the flames, the hot gas and the hot ash are also produced and projected out of the exit hole in addition to the colored smoke. The heat, flame and hot ash can cause fires when the prior art devices are placed on flammable materials such as dried grass, leaves, paper or furniture and also cause burns and injury to a user and people in the nearby vicinity if the prior art devices are not used correctly and if the correct personal protective equipment is not worn.
Thus, there is a present need for a safe smoke device. The present disclosure has solved the above problems with the below disclosed safe smoke device. The smoke device is safer to use by vastly reducing sparks, hot ash and flames from exiting the device and preventing fire and injury. Another disclosed advantage of the present disclosed smoke device is that as the generated smoke passes through baffles or chambers and cools more than in devices with a single chamber or no chamber. The cooler smoke gives improved color and less bleaching resulting in richer colors.
The present disclosure is a smoke device which has the ability to release different colors of smoke therefrom in a safe manner.
The smoke device includes a container, a base/base plate, a plate having at least one exit hole, a blend of chemicals contained in the container and a mechanical means by which generated smoke is prevented from directly exiting through the at least one exit hole without first being redirected in one or more directions. The plate acts to reduce the diameter of the container at the exit hole(s). This can be done in a variety of methods and with a variety of materials. A plug or a plug style choke can replace the plate of the smoke device. The exit hole(s) in the plate can be called a choke. Thus, the container is said to be choked. One example of the blend of chemicals in the container is Potassium Nitrate (an oxidizer), Sulphur (a fuel), Colored Smoke Dye and Lactose. Another example of the blend of chemicals in the container is Potassium Chlorate, Lactose and Colored Smoke Dye.
The mechanical means by which generated smoke is prevented from directly exiting through the at least one exit hole without first being redirected in one or more directions may include a plurality of baffles which have at least one hole therein and a plurality of chambers formed by the plurality of baffles.
The container may be made from cardboard, plastic, metal, alloy or a composite material.
The base/base plate is located in the bottom of the container. The base/base plate seals the bottom of the contain such that the blend of chemicals contained in the container does not leak out of the container. The sealing of the base/base plate to the container may be by means of a glue, a sealant, an epoxy, a groove and O-ring seal, a friction fit seal or any equivalent sealing apparatus or by welding, soldering, riveting, securing screws through holes formed in the container and the base/base plate or other equivalent attachment methods. The base/base plate may be made from cardboard, plastic, metal, alloy or a composite material. The base/base plate may be formed from a single part/piece or from multiple parts/pieces.
The plate having at least one exit hole therein is attached to a top of the container. The plate is attached to the top of the container by using a glue, a sealant, an epoxy, a groove and O-ring seal, a friction fit seal or equivalent attachment apparatus or by welding, soldering, riveting, securing screws through holes formed in the container and the plate or other equivalent attachment methods. There is at least one exit hole in the plate which may be formed in the geometric center of the plate or may be off set from the geometric center of the plate. Moreover, there may be a plurality of holes in the plate. The holes may be circular, square or any other geometric or polygonal shape. The range of the hole sizes is dependent on the size (diameter) of the smoke device and the holes range between 5 mm-20 mm but may be smaller or bigger depending on the size of the smoke device. The plate may be made from cardboard, plastic, metal, alloy or a composite material.
The container of the smoke device has a plurality of chambers, a minimum of two chambers. The plurality of chambers is formed by the plurality of baffles. The distance between adjacent chambers may be the same for all chambers or there may be difference distances between adjacent chambers. The baffles may be spaced apart by using support posts and the top most baffle in the smoke device may be attached to the plate.
Each of the baffles has one or more holes therein. The range of the hole sizes in the baffles is dependent on the size (diameter) of the smoke device and the holes in the baffles range between 5 mm-20 mm but maybe smaller or bigger depending on the size of the smoke device. The plurality of baffles is placed in a staggered formation such that the hole(s) formed in each baffle is offset from the hole(s) in an adjacent/neighboring baffle. The hole(s) in each of the baffles are offset with regards to each neighboring baffle. The hole(s) in each baffle may be circular, square or any other geometric or polygonal shape. The hole(s) in each baffle may be formed in the geometric center of the baffle or may be off set from the geometric center of the baffle. Moreover, the holes in each baffle and/or each adjacent/neighboring baffle may have a different size or a same size in order to solve the problem of reducing sparks, hot ash and flames from exiting the smoke device, which prevents fire and injury and also cools the generated smoke thereby providing improved smoke color and less bleaching resulting in richer colors. The plurality of baffles and the plurality of chambers having offset holes serve to dramatically reduce and in some cases eliminate the hot ash, sparks and flame being emitted from the exit hole(s) and significantly reduces the chance of causing fires or injury to people. Thus, the disclosed smoke device is far safer than the existing prior art designs. Also, the plurality of baffles may include one or more spiral baffle(s) in which the smoke moves up a spiral shaped tube or chute to an exit point of the spiral baffle. Each of the baffles may be made from cardboard, plastic, metal, alloy or a composite material. Furthermore, each of the baffles may be made from a different material or some baffles may be made from the same material while other baffles are made from a different material in order to increase the cooling of the smoke and improve the smoke color and less bleaching resulting in richer colors. For example, the two lower most baffles in the container are made from metal or alloy and the upper most baffle in the container is made from cardboard, plastic or a composite material. Another example may include the upper most baffle may be made from a metal or alloy, the bottom most baffle may be made from plastic or a composite material and one or two additional baffles are made from cardboard. The above disclosed examples are only a few specific disclosed examples but different examples of different baffles comprised of different materials which solve the problem of reducing sparks, hot ash and flames from exiting the smoke device, prevents fire and injury and also cooling the generated smoke and improving the smoke color and less bleaching resulting in richer colors are also part of the disclosure of this smoking device. Each of the baffles may be formed from a single part/piece or from multiple parts/pieces. Each of the baffles are attached or secured to an inner surface of the container by using a glue, a sealant, an epoxy, a groove and O-ring seal, a friction fit seal or equivalent attachment apparatus or by welding, soldering, riveting, securing screws through holes formed in the container and the baffles or other equivalent attachment methods. Moreover, each of the baffles are position above the top level of the blend of chemicals which is contained in the container.
The smoke device and design incorporating the plurality of baffles and multiple chambers may function with and by all existing ignition devices and methods such as a safety fuse, an electric igniter/electric match, friction or strike (i.e. like a match), a pull pin/percussion or fly-off lever. The range of distances between each of the baffles is dependent on the size (length and diameter) of the smoke device and the distance between each of the baffles can range between 10 mm and 100 mm but could be smaller or bigger depending on the size of the smoke device. The types of ignition come from the ways in which heat can be generated such as heat from an external source, friction, electrical and impact (percussion). Within these general groups the actual mechanism of generating the heat can vary widely and many involve more than one type connected together known as a pyrotechnic train.
The device is mainly for civilian use but may also be applied to military and law enforcement training devices. The smoke device is not a military specific product. The smoke device reduces and/or eliminates sparks, hot ash and flames from exiting the smoke device and thus is safer than existing prior art products. Therefore, the smoke device is safer to use because the smoke device vastly reduces sparks, hot ash and flames from exiting the smoke device, prevents fire and injury and the generated smoke passing through the baffles and/or chambers cools more than other prior art devices with a single chamber or no chamber. Thus, this cooler generated smoke gives an improved color and less bleaching resulting in richer colors.

As shown in
It is noted that the use of the baffles or similar physical barrier within the container of the smoke device to prevent or significantly reduce the sparks, flame and ash produced from the burning smoke composition from exiting the smoke device. This is done by causing a gas jet that is produced to change direction within the smoke device before exiting through the plate, plug or plug style choke. This can be accomplished by physically with baffle plates with holes, a spiral baffle and also part(s) of the baffle material removed. The different methods suit different manufacturing technics depending on the size of the smoke device and costs.

The smoke device and design incorporating the plurality of baffles and multiple chambers may function with and by all existing ignition devices and methods such as a safety fuse, an electric igniter/electric match, friction or strike (i.e. like a match) and percussion or fly-off lever. Thus, the blend of chemicals contained in the container may be heated with any of the above ignition devices and methods to generate the smoke or colored smoke. The range of distances between each of the baffles is dependent on the size (length and diameter) of the smoke device and the distance between each of the baffles can range between 10 mm and 100 mm but could be smaller or bigger depending on the size of the smoke device. The types of ignition come from the ways in which heat can be generated such as heat from an external source, friction, electrical and impact (percussion). Within these general groups the actual mechanism of generating the heat can vary widely and many involve more than one type connected together known as a pyrotechnic train.
The device is mainly for civilian use but may also be applied to military and law enforcement training devices. The smoke device is not a military specific product.
