Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention provides a high-safety electric ignition device for igniting the engine of a fire-fighting drone through improvement. Figure 1-Figure 3 As shown, it includes an electric ignition device body 13, which is composed of a moisture-proof tape 1, a cup body 2, a semiconductor bridge medicine head 6, a cup cover 7 and a foot line 9. The ends of the foot line 9 are untied and connected to the designated positions of the ignition part of the fire-fighting drone engine respectively. A spacer paper 4 is clamped on one side of the inner wall of the cup body 2, and an ignition powder 5 is laid on the top of the spacer paper 4. The ignition powder 5 ignites the spacer paper 4 and then ignites the main loading agent. A clamping groove 10 is opened on the inner wall side of the cup body 2 away from the spacer paper 4. The cup cover 7 is threadedly connected to the inside of the clamping groove 10, so that a closed space is formed inside the cup body 2. Flame injection holes 14 are opened at equal distances on the bottom of the cup body 2. The flame and pressure generated by the main loading agent 3 are transmitted to the fire-fighting drone engine through the flame injection holes of the cup body 2. The fire-fighting drone engine starts smoothly after reaching a certain pressure.

[0022] Furthermore, a through hole 11 is opened in the middle of the bottom of the cup cover 7 , and the inner wall of the through hole 11 is coated with solid glue 12 , so that the semiconductor bridge drug head 6 is stably arranged in the cup cover 7 .

[0023] Furthermore, the semiconductor bridge medicine head 6 is bonded to the inside of the cup cover 7 by solid glue 12, and the foot wires 9 are welded to the two sides of the top of the semiconductor bridge medicine head 6. The ends of the foot wires 9 are untied and connected to the designated positions of the ignition part of the fire-fighting drone engine respectively. When the high-safety electric ignition device is energized, the electric energy is heated by the semiconductor bridge to ignite the semiconductor bridge medicine head 6, and the flame generated by the semiconductor bridge medicine head 6 ignites the ignition powder 5, and the ignition powder 5 then ignites the spacer paper 4.

[0024] Furthermore, main charge agent 3 is filled between the spacer paper 4 and the bottom of the cup body 2, and the main charge agent 3 is ignited. The flame and pressure generated by the main charge agent 3 are transmitted to the fire-fighting drone engine through the flame injection hole of the cup body 2. The spacer paper 4 is a cylindrical structure, and the diameter of the spacer paper 4 is equal to the inner diameter of the cup body 2. The assembly sequence is to press the main charge agent 3, install the spacer paper 4, and finally install the gunpowder 5 and press it.

[0025] Furthermore, the bottom of the cup body 2 is bonded to the top of the moisture-proof tape 1, and a hexagonal thin nut 8 is bonded to one side of the outside of the cup cover 7 through solid glue 12. The hexagonal thin nut 8 is fixed to the cup cover 7 through fixing glue 12, which facilitates production and improves production efficiency.

[0026] Furthermore, the foot line 9 is a tinned copper wire, and gunpowder is dripped on the connection between the foot line 9 and the semiconductor bridge lead 6, and the gunpowder is dripped and then dried.

[0027] Working principle: When in use, untie the ends of the foot line 9 and connect them to the designated positions of the ignition part of the fire-fighting drone engine. When the high-safety electric ignition device is energized, the electric energy is heated by the semiconductor bridge to ignite the semiconductor bridge medicine head 6. The flame generated by the semiconductor bridge medicine head 6 ignites the ignition powder 5. The ignition powder 5 then ignites the spacer paper 4, and then ignites the main agent 3. The flame and pressure generated by the main agent 3 are transmitted to the fire-fighting drone engine through the flame injection hole of the cup body 2. The fire-fighting drone engine starts smoothly after reaching a certain pressure. The hexagonal thin nut 8 is fixed to the cup cover 7 by the fixing glue 12, which is convenient for production and improves production efficiency. The cup cover 7 is threadedly connected to the inside of the clamping groove 10 to form a closed space inside the cup body 2, thereby enhancing the reliability of the cup body 2.
