[0001] This utility model relates to the field of prop smoke bombs, and in particular to an electronic prop smoke bomb. Background Technology
[0002] In some film and television shooting, military exercises, live-action CS and other scenarios, prop smoke grenades are needed to produce a large amount of smoke effects. However, traditional prop smoke grenades cannot control the delay of smoke generation time. They usually use gunpowder fuses to activate. When the fuse is lit, it will burn rapidly and trigger the reaction of the main charge, thereby producing smoke. In addition, prop smoke grenades cannot be reused. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an electronic smoke bomb, comprising: a projectile body, a firing pin on the projectile body, a protective chamber inside the projectile body, a smoke chamber arranged between the protective chamber and the projectile body, a battery, a circuit board and an arc igniter inside the protective chamber, a smoke pellet inside the smoke chamber, a contact switch pressed down by the firing pin, the contact switch being connected to the battery, the battery being connected to the circuit board, the circuit board being connected to the arc igniter, the arc igniter being connected to the smoke pellet, and a smoke outlet hole being opened on the firing pin or the projectile body.
[0005] Preferably, the smoke chamber has a connecting hole, through which the electric arc igniter is connected to the smoke cake.
[0006] Preferably, the upper end of the projectile is connected to an upper cover, and the lower end of the projectile is connected to a bottom cover.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0022] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0023] Unless otherwise specified, physical quantities in formulas should be understood as basic quantities of SI base units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation, or integration.
[0024] Example:
[0025] refer to Figure 1 and Figure 2An electronic smoke grenade includes: a projectile body 18, a firing pin 1 movably mounted on the projectile body 18, a protective chamber 2 installed inside the projectile body 18, the protective chamber 2 can be slightly interference-fitted with the projectile body 18, or can be glued inside the projectile body 18, a smoke chamber 3 is arranged between the protective chamber 2 and the projectile body 18, a battery 4, a circuit board 5 and an arc igniter 6 are installed inside the protective chamber 2, and a smoke pellet 7 is contained inside the smoke chamber 3. When the firing pin 1 is pressed down, the firing pin 1 presses down on a contact switch 8, that is, the contact switch 8 is arranged below the firing pin 1. The contact switch 8 is connected to the battery 4, the battery 4 is connected to the circuit board 5, the circuit board 5 is connected to the arc igniter 6, the arc igniter 6 is connected to the smoke pellet 7, and a smoke outlet 16 is opened on the firing pin 1 or the projectile body 18. When the smoke outlet 16 is opened on the firing pin 1, the interior of the firing pin 1 is hollow and communicates with the smoke chamber 3 and the smoke outlet 16, so that smoke can be emitted through the smoke outlet 16. Therefore, when the striker 1 is pressed, the bottom of the striker 1 presses down to contact the switch 8, and then the battery 4 powers the circuit board 5. The circuit board 5 then controls the arc igniter 6 to ignite, thereby igniting the smoke pellet 7 and producing smoke. The circuit board 5 can be programmed to delay ignition after the battery 4 powers the circuit.
[0026] refer to Figure 1 and Figure 2 The smoke chamber 3 has a connecting hole 9, through which the arc igniter 6 connects to the smoke cake 7, thereby igniting the smoke cake 7.
[0027] refer to Figure 1 and Figure 2 The upper end of the projectile 18 is connected to the upper cover 10, and the lower end of the projectile 18 is connected to the bottom cover 11. The outer periphery of the upper cover 10 and the bottom cover 11 is provided with external threads, and the inner side of the projectile 18 is provided with internal threads. The upper cover 10 and the bottom cover 11 are threadedly engaged with the projectile 18. The firing pin 1 is fitted with a safety sleeve 12, and a safety bolt 13 is engaged between the safety sleeve 12 and the firing pin 1. The bottom of the safety sleeve 12 abuts against the upper cover 10. The firing pin 1 passes through the upper cover 10 and presses down the contact switch 8. The firing pin 1 is fitted with a spring 17, and the two ends of the spring 17 abut against the safety sleeve 12 and the upper cover 10 respectively, to prevent the firing pin 1 from pressing down the contact switch 8 when it is not subjected to external force. When needed, the operator pulls out the safety pin 13, allowing the firing pin 1 to detach from the safety sleeve 12. Then, the safety sleeve 12 is removed, and the firing pin 1 is pressed down, causing the bottom of the firing pin 1 to press down on the contact switch 8. This powers the circuit board 5, which in turn controls the arc igniter 6 to ignite the smoke pellet 7, which then produces smoke.
[0028] refer to Figure 1 and Figure 2A limiting plate 14 extends from the bottom of the smoke chamber 3 toward the striker 1. A limiting groove 15 is provided at the bottom of the striker 1. The limiting groove 15 cooperates with the limiting plate 14 to control the maximum distance of the striker 1 toward the smoke chamber 3, so as to prevent the striker 1 from pressing the smoke cake 7. In addition, the size of the bottom of the striker 1 is larger than the size of the hole in the top cover 10 when the head of the striker 1 passes through the top cover 10, so as to prevent the striker 1 from falling off.
[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
