bang device

Abstract

This disclosure discloses a detonation device comprising a launching barrel defining an internal accommodating space; a bottom closure disposed at the bottom of the launching barrel, sealing the bottom of the accommodating space; a first propellant layer disposed within the accommodating space above the bottom closure; a separator disposed within the accommodating space, positioned above and abutting against the first propellant layer; a second propellant layer disposed within the accommodating space above the separator; and a top blocking member disposed within the accommodating space, positioned above the second propellant layer to seal the accommodating space. Through these means, the separator and the top blocking member physically divide the accommodating space, preventing different propellant layers from mixing before detonation, thereby achieving the expected technical effect of multi-layered and multi-color ejection upon activation.

Claims

1. A detonation device, comprising: a launching barrel defining an accommodating space; a bottom closure disposed at the bottom of the launching barrel and closing the bottom end of the accommodating space; at least one first agent layer disposed within the accommodating space above the bottom closure; a partition disposed within the accommodating space, the partition being located above and abutting against the at least one first agent layer; at least one second agent layer disposed within the accommodating space above the partition; and a top blocking member disposed within the accommodating space, the top blocking member being located above the at least one second agent layer to close the accommodating space.

2. The popping device as described in claim 1, wherein, The outer periphery of the top blocking member and the partition member are in close contact with the inner wall of the launch barrel.

3. The detonation device as claimed in claim 1 further includes an ignition member, wherein a perforation is formed on the surface of the launching barrel, and the ignition member is inserted through the perforation and extends into the at least one first agent layer.

4. The popping device as described in claim 1, wherein, The bottom closure is a solid-filled inner plug structure.

5. The popping device as described in claim 1, wherein, The bottom closure is an inner plug with a U-shaped cross-section. The bottom closure has a flat top wall and an annular side wall extending downward from the periphery of the flat top wall. The annular side wall is tightly fitted to the inner bottom of the receiving space of the launch barrel, and the flat top wall is supported by the at least one first agent layer.

6. The popping device as described in claim 1, wherein, The at least one first agent layer and the at least one second agent layer have different color characteristics.

7. The popping device as described in claim 1, wherein, The at least one first agent layer and the at least one second agent layer have different particle sizes.

8. The popping device as described in claim 1, wherein, The accommodating space above the top barrier is an empty section without filling.

9. The popping device as described in claim 1, wherein, The divider and the top barrier are made of cardboard or plastic sheeting.
