Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of riot control ammunition, specifically a hand-thrown incendiary colored smoke bomb. Background Technology
[0002] Currently, the WJ99-1 37mm series smoke grenades have some applications in military and police fields, but they have many shortcomings that make them difficult to meet actual needs. This type of smoke grenade has a diameter of 37mm and a total weight of 185g±5g. This specific size and weight design brings obvious deficiencies.
[0003] While existing smoke grenades can generate smoke to impair visibility and conceal actions, most suffer from the following problems:
[0004] Single-color smoke: Most smoke grenades only produce smoke of one color, such as white or gray. In complex environments, a single smoke color is insufficient for clear differentiation and warning, failing to meet the needs of diverse scenarios. For example, when it is necessary to quickly identify specific areas or convey different signals, a single-color smoke grenade cannot effectively accomplish the task.
[0005] Unreliable ignition methods: Some smoke grenades have complex ignition structures that are easily affected by environmental factors such as humidity and high temperatures, leading to ignition failure or inaccurate ignition timing. Some smoke grenades using electronic ignition may malfunction when subjected to strong vibrations or electromagnetic interference, affecting their effectiveness.
[0006] Safety concerns: Some smoke grenades, due to poorly designed ignition devices, pose a risk of accidental ignition during storage and transportation, creating a safety hazard for operators and the surrounding environment. Furthermore, some smoke grenades may generate high temperatures during combustion, easily causing fires, especially in environments with abundant flammable materials, making safety difficult to guarantee. Utility Model Content
[0007] This utility model addresses the technical problems existing in the prior art by providing a hand-thrown incendiary colored smoke cartridge to solve the problems of the existing colored smoke cartridges having a single smoke color and unreliable ignition method.
[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hand-thrown incendiary colored smoke cartridge includes a shell, wherein the shell is provided with a plurality of evenly distributed smoke column fixing chambers, and each smoke column fixing chamber is provided with a colored smoke column; the shell is also provided with a pill that contacts each colored smoke column for igniting the colored smoke column; the shell is also provided with a strip of powder for igniting the pill; the shell is also provided with a ignition mechanism adjacent to the strip of powder, and the ignition mechanism includes a delayed ignition tube for igniting the strip of powder.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the drug strip extends inward and contacts the inner wall of the colored smoke column.
[0011] Furthermore, the housing is provided with a storage shell for filling ignition tablets. The storage shell has an ignition port channel for placing the ignition tablet and several ignition ports corresponding to each flame delay ignition tube.
[0012] Furthermore, the ignition tablet is a black powder tablet made from a mixture of potassium nitrate, sulfur, and charcoal.
[0013] Furthermore, the drug strip is a delayed-action drug strip made by mixing strontium nitrate, potassium perchlorate, and phenolic resin.
[0014] Furthermore, the ignition mechanism also includes a fuse body mounted on the housing for fixing the delay ignition tube; a firing pin block is hinged to the fuse body via a pivot pin, a firing pin is formed on the firing pin block, and a torsion spring connected to the firing pin block is also installed in the fuse body; the torsion spring is used to drive the firing pin block to deflect so that the firing pin needle punctures and ignites the delay ignition tube.
[0015] Furthermore, the firing mechanism also includes a safety grip hinged to the outside of the housing and used to press the firing pin block to the safety position, and the housing is also provided with a safety pin for locking the safety grip.
[0016] Furthermore, smoke exhaust holes are provided at both the top and bottom of the housing.
[0017] Furthermore, a sealing film is provided at the smoke exhaust port.
[0018] The beneficial effects of this utility model are:
[0019] 1) This hand-thrown incendiary colored smoke grenade achieves efficient ignition and reliable firing through a unique design. The propellant strip inside the casing extends inward and contacts the inner wall of the colored smoke column. The strip is made of a delay propellant strip, a mixture of strontium nitrate, potassium perchlorate, and phenolic resin, which stably delays combustion, buying time for operators to evacuate safely. Simultaneously, the delayed ignition tube in the firing mechanism can be precisely fired, igniting the propellant strip. The strip then transfers the flame to a black powder sheet made of potassium nitrate, sulfur, and charcoal, ultimately igniting the colored smoke column. The entire ignition process is orderly and efficient, ensuring reliable firing when needed. Smoke colors: red, yellow, green, and white. Having four smoke colors allows for more signal transmission on the battlefield.
[0020] 2) Colored smoke cartridges possess a comprehensive safety protection and operational assurance mechanism. In the firing mechanism, the safety grip is hinged to the outer shell, pressing the firing pin block to the safety position and locking it with a safety pin. This effectively prevents accidental activation of the delay ignition tube when not in use, avoiding the dangers of misoperation. When needed, simply pull out the safety pin and operate the safety grip to release the safety, causing the torsion spring to deflect the firing pin block, allowing the firing pin to ignite the delay ignition tube. This ensures operator safety and improves the safety and controllability of colored smoke cartridge use.
[0021] 3) Smoke vents are provided at both the top and bottom of the casing, allowing the colored smoke generated by the burning smoke column to be quickly and smoothly discharged from the casing, creating a noticeable colored smoke effect over a wider area, meeting the needs of deterrence, warning, or information transmission. Simultaneously, the sealing film at the smoke vents effectively seals the vents before use, preventing external moisture and dust from entering the casing, protecting the colored smoke column and other components from damage, ensuring the stable performance of the smoke cartridges during storage and transportation, and extending their service life.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0028] Due to limitations in its diameter and overall mass, the amount of smoke-generating agent it can hold is relatively small, resulting in a small amount of smoke. In open outdoor environments or large event venues, the small amount of smoke is insufficient to create a sufficiently significant and persistent smoke area, failing to effectively conceal targets, interfere with enemy vision, or provide large-scale warnings.
[0029] For example, in military operations, when smoke is needed for tactical cover or to mark specific areas, the smoke produced by the WJ99-1 smoke grenade may be quickly dispersed or diluted by the wind, failing to meet the requirements of operational operations for smoke duration and coverage. To address this, this invention designs a hand-thrown incendiary colored smoke grenade.
[0030] like Figure 1-3 The aforementioned hand-thrown incendiary colored smoke bomb includes a shell 1, which has several evenly distributed smoke column fixing chambers, each containing a colored smoke column 2; the shell 1 also contains a powder tablet 3 that contacts each colored smoke column 2 for igniting the colored smoke column 2; the shell 1 also contains a powder strip 3.1 for igniting the powder tablet 3; and the shell 1 is further provided with a ignition mechanism 4 adjacent to the powder strip 3.1, the ignition mechanism 4 including a delayed ignition tube 4.1 for firing the powder strip 3.1.
[0031] The hand-thrown incendiary colored smoke bomb has a shell 1 as the main body, with multiple smoke column fixed chambers evenly distributed inside. Each chamber is equipped with a colored smoke column 2, which is the core for producing smoke of a specific color. It is composed of specific chemical substances and reacts to release colored smoke when burned.
[0032] The housing 1 contains a pill 3 that comes into contact with the colored smoke column 2. The pill 3 is made of a flammable substance that can generate a flame with sufficient heat, and is used to ignite the colored smoke column 2.
[0033] Inside the casing 1 is also a strip 3.1, which uses a chemical substance with delayed combustion properties to ignite the tablet 3. The delay time can be set by controlling its own parameters to ensure the safe evacuation of the operator.
[0034] The ignition mechanism 4 is installed on the housing 1, adjacent to the propellant strip 3.1. The delayed ignition tube 4.1 therein is ignited by a specific operation to generate a flame or high temperature, which is the starting point for triggering the entire combustion and smoke generation process.
[0035] Specifically, the propellant strip 3.1 extends inward and contacts the inner wall of the colored smoke column 2. After the delayed ignition tube 4.1 of the ignition mechanism 4 is ignited, the propellant strip 3.1, by virtue of its contact with the inner wall of the colored smoke column 2, can efficiently and directly transfer the high temperature and flame generated by combustion to the colored smoke column 2, thereby igniting the colored smoke column 2 and causing it to produce colored smoke. At the same time, the delayed combustion characteristics of the propellant strip 3.1 can also buy time for the operators to evacuate safely.
[0036] In one embodiment, the housing 1 is provided with a storage shell 3.2 for filling the ignition tablet 3. The storage shell 3.2 is provided with an ignition port channel for placing the ignition strip 3.1 and several ignition ports corresponding to each flame delay ignition tube 2.1.
[0037] The housing 1 has a powder storage shell 3.2 to hold the ignition tablet 3. The powder storage shell 3.2 has an ignition port channel for placing the powder strip 3.1, so that the powder strip 3.1 can be inserted into it to ignite the powder tablet 3. It also has an ignition port corresponding to the flame delay ignition tube 2.1, so that the delay ignition tube 2.1 can transfer the flame to the powder storage shell 3.2 to ignite the relevant components, thereby realizing the orderly ignition and smoke generation of the colored smoke bomb.
[0038] In addition, the ignition tablet 3 is a black powder tablet made of potassium nitrate, sulfur and charcoal; the ignition strip 3.1 is a delay strip made of strontium nitrate, potassium perchlorate and phenolic resin.
[0039] Inside the casing 1, a black powder pellet 3, made from a mixture of potassium nitrate, sulfur, and charcoal, serves as the ignition pellet. This pellet is highly flammable and can rapidly generate a large amount of heat and flame. A delay charge 3.1, made from a mixture of strontium nitrate, potassium perchlorate, and phenolic resin, achieves stable delayed combustion due to its composition. When the ignition mechanism is triggered, the flame enters through the ignition port corresponding to the flame delay ignition tube on the storage casing 3.2, first igniting the delay charge 3.1. After the charge 3.1 burns for a predetermined time, the flame is transferred to the black powder pellet 3 through the ignition port channel on the storage casing 3.2 where the charge is placed. The high-temperature flame generated by the rapid combustion of the pellet 3 ultimately ignites the colored smoke column, causing it to release colored smoke.
[0040] The ignition mechanism 4 further includes a fuse body 4.2 mounted on the housing 1 for fixing the delay ignition tube 4.1; a firing pin block 4.3 is hinged inside the fuse body 4.2 via a pivot pin, and a firing pin 4.4 is formed on the firing pin block 4.3; a torsion spring 4.5 connected to the firing pin block 4.3 is also installed inside the fuse body 4.2; the torsion spring 4.5 is used to drive the firing pin block 4.3 to deflect so that the firing pin 4.4 punctures and ignites the delay ignition tube 4.1.
[0041] The firing mechanism 4 also includes a safety grip 4.6 hinged to the outside of the housing 1 and used to press the firing pin block 4.3 to the safety position. The housing 1 is also provided with a safety pin 4.7 for locking the safety grip 4.6.
[0042] On the housing 1, the fuse body 4.2 of the ignition mechanism 4 serves to fix the delayed ignition tube 4.1. A firing pin block 4.3 is hinged to the fuse body 4.2 via a pivot pin. The firing pin block 4.3 is equipped with a firing pin 4.4. A torsion spring 4.5 connected to the firing pin block 4.3 is also installed inside the fuse body 4.2. When the ignition mechanism is triggered, the torsion spring 4.5 releases its elastic potential energy, causing the firing pin block 4.3 to deflect around the pivot pin, thereby causing the firing pin 4.4 to pierce the delayed ignition tube 4.1, igniting it and initiating the subsequent combustion and smoke generation process of the colored smoke bomb.
[0043] Specifically, smoke exhaust holes are provided at the top and bottom of the housing 1.
[0044] Inside the casing 1, the colored smoke column 2 is ignited, producing a large amount of colored smoke. Since there are smoke vents at the top and bottom of the casing 1, these vents form a channel for smoke discharge. During smoke generation, the internal air pressure increases, and the smoke is quickly and smoothly discharged from the casing 1 through the smoke vents at the top and bottom, thus creating a noticeable colored smoke effect over a wider area, meeting the needs for deterrence, warning, or information transmission.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
