Abstract
Description
Technical Field
[0001] This utility model relates to the field of police equipment technology, specifically to a jet-type tear gas canister. Background Technology
[0002] Tear gas is increasingly being used in a wide range of missions, playing a crucial role as a non-lethal weapon. These missions often involve complex scenarios involving flammable and explosive materials. In situations involving hostage situations or the seizure of vital supplies under flammable and explosive conditions, the limitations of traditional non-lethal projectile weapons mean that the tear gas could ignite the primer or explode, potentially igniting or detonating the environment and causing significant harm to personnel, hostages, or vital supplies. Utility Model Content
[0003] The purpose of this invention is to provide a jet-type tear gas canister.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A jet-propelled tear gas grenade includes a pull ring, a grip, a projectile body, and a pin. The projectile body further includes a compressed gas canister, a cavity, and a firing device. The pull ring and the pin are snap-fitted together, and the pin and the firing device are snap-fitted together. The firing device is further provided with a pin, a rod, a spring, and a grip. The spring is hinged to the rod. The projectile body contains a compressed gas canister and a cavity, with the cavity located in an annular cavity between the inner wall of the projectile body and the outer wall of the compressed gas canister.
[0006] Preferably, the compressed gas tank contains compressed carbon dioxide.
[0007] Preferably, the cavity contains a tear gas agent, which is a prior art and will not be described in detail here.
[0008] Preferably, the jet-type tear gas canister is manufactured using 3D printing technology.
[0009] Preferably, the jet nozzle at the tail of the jet-type tear gas canister is designed with an angled nozzle.
[0010] This utility model has the following beneficial effects:
[0011] 1. Wide range of applications: Due to its own triggering mechanism and innovative design of compressed gas as carbon dioxide, jet-type tear gas cannons are no longer limited to flammable and explosive scenarios. They use compressed carbon dioxide as a power source to release the tear gas, and carbon dioxide can isolate oxygen and thus play a fire extinguishing role, further eliminating the risk of combustion and explosion.
[0012] 2. Due to the innovative jet-propelled triggering mechanism, the projectile remains intact after use. It can be reused after replacing the compressed gas tank and refilling the tear gas, which greatly saves on usage costs.
[0013] 3. The design and production process combines 3D design and 3D printing. The precise parametric design facilitates continuous updates and iterations to meet the needs of the armed forces.
[0014] 4. The tail exhaust nozzle adopts an angled design. This design allows the projectile to maintain its spin after launch, causing it to bounce and rotate on the ground, thus greatly reducing the risk of enemy counter-launch.
[0015] 5. Compressed gas tanks are characterized by high strength, strong corrosion resistance, and easy processing, which extends the storage life and allows for the storage of high-pressure gases at high pressures. The projectile is not affected by the explosion, which facilitates secondary processing and recycling, and can minimize the cost of use.
[0016] 6. Threaded assembly design: This design provides fastening and sealing, shock absorption and cushioning, anti-static properties, and electrical insulation, strictly ensuring the airtightness of the product.
[0017] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] like Figure 1 As shown, a jet-type tear gas grenade includes a pull ring 1, a grip 7, a projectile body 5, and a pin 9. The projectile body 5 also includes a compressed gas tank 6, a cavity 8, and a firing device 10. The pull ring 1 and the pin 9 are snapped together, and the pin 9 and the firing device 10 are snapped together. The firing device 10 is also provided with a pin 4, a rod 3, a spring 2, and a grip 7. The spring 2 is hinged to the rod 3. The projectile body 5 contains a compressed gas tank 6 and a cavity 8, which are located in the gap between the projectile body 5 and the compressed gas tank 6. The outer shell of the projectile body 5 is made of plastic, and the overall weight does not exceed 200g.
[0025] Preferably, the compressed gas tank 6 contains compressed carbon dioxide, and the compressed gas tank 6 contains 12g of carbon dioxide. The material is a steel cylinder, and the weight of the steel cylinder is 54g.
[0026] Preferably, the cavity 8 contains a tear gas agent.
[0027] Preferably, the jet-type tear gas canister is made using 3D printing technology. By combining three-dimensional design and 3D printing technologies, the precise parametric design facilitates continuous updates and iterations to meet the needs of the armed forces. After use, the canister remains intact and can be reused after replacing the compressed gas canister and refilling the tear gas. The cost per use is no more than 5 yuan, which greatly saves on usage costs.
[0028] Preferably, the jet nozzle at the tail of the jet-type tear gas grenade adopts an oblique design. This design can maintain the spin of the projectile after it is triggered, causing the projectile to bounce and rotate on the ground, thereby greatly reducing the risk of enemy counter-throwing.
[0029] When in use, pulling the ring 1 causes the pin 9 to disengage from the firing device 10. When the lever 7 is ejected, the spring 2 is released. The spring 2 drives the push rod 3 to push the ejector pin 4. The ejector pin 4 punctures the compressed gas canister 6, thereby realizing the jet function. Affected by the compressed carbon dioxide, the tail of the projectile 5 quickly releases tear gas, thereby achieving the tear gas effect. It also isolates oxygen by releasing carbon dioxide, playing a fire extinguishing role and further eliminating the risk of combustion and explosion.
[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
