Description

Technical Field

[0001] This invention pertains to ignition technology, specifically relating to a safe ignition device that does not contain pyrotechnic components. Background Technology

[0002] Ignition devices are used to ignite products, thereby enabling them to achieve various performance characteristics. They are a direct guarantee for the normal operation of products and are used in various fields and products, including military and civilian applications.

[0003] Currently, the ignition devices used in the market contain pyrotechnic components. Even safety ignition devices contain ignition charges. They require special sites and transportation vehicles for storage and transportation, which poses certain safety hazards and causes a lot of inconvenience.

[0004] Patent CN201921909853.1 discloses a safety ignition device for an electric toy fireworks effect tube. The patent describes that "the lead wire can be separated by a fixing post and a lead wire groove, improving the safety of use; the inner tube can be freely disassembled by the cooperation of a card plate, a card block, and a card slot, saving time and effort." However, the ignition device described in this patent still contains an electronic ignition head, which falls under the category of dangerous goods, and presents many inconveniences in storage and transportation.

[0005] Patent CN202021859112.X discloses a multi-arc ignition device, which describes that "the igniter is equipped with an ignition discharge electrode group and an ignition control circuit, which can realize remote ignition operation and improve ignition efficiency." However, the ignition device described in this patent uses an acceleration sensor to control the ignition circuit. During transportation and other processes, the sensor may accidentally issue a command, causing accidental ignition, which poses a certain safety hazard. Summary of the Invention

[0006] The purpose of this invention is to provide a safe ignition device that does not contain pyrotechnic materials, thereby solving the problems mentioned in the background art: the device contains hazardous materials, making it difficult to store and transport. Furthermore, the ignition device described in this invention features a sealing ring structure, which facilitates the establishment of ignition pressure and allows it to adapt to different ignition environments, such as vacuum or humid environments.

[0007] The technical solution for achieving this invention is as follows: a safety ignition device without pyrotechnics, comprising a device body, a sealing ring, and an ignition assembly; the device body includes a shell, insulating material, elastic material, two leads, two terminals, and two arc-shaped locking blocks. A sealing groove is provided on the upper part of the outer circumference of the shell, and the sealing ring is disposed within the sealing groove. Two symmetrical terminal mounting slots are provided on the top surface of the shell, each slot containing one terminal. A circular groove is formed on the bottom surface of the shell. The ignition assembly is disposed within the circular groove and fixed by the two arc-shaped locking blocks. Elastic material is provided between the ignition assembly and the circular groove to secure the ignition assembly. The two leads are arranged parallel to each other within the shell, with one end of each lead connected to a terminal for use with an external lead, and the other end connected to the ignition assembly. The shell is filled with insulating material.

[0008] Compared with the prior art, the significant advantages of this invention are:

[0009] (1) The ignition device described in this invention does not contain any dangerous materials. The ignition component is heated by an electric heating wire. It can be treated as an ordinary part during storage, transportation and other processes. Compared with similar pyrotechnic products, it is subject to very few restrictions and can also achieve the same ignition performance.

[0010] (2) The ignition device described in this invention is equipped with a sealing component, and after installation it is a completely sealed structure. Compared with similar ignition devices, it is easier to establish ignition pressure and improve ignition reliability. At the same time, it can be used in other ignition environments such as vacuum and humid environments.

[0011] (3) The ignition component in the ignition device described in this invention is a detachable structure, which is easy to replace and reduces costs. At the same time, different ignition components can be customized according to different ignition requirements. Attached Figure Description
