Detailed Description

Referring to fig. 1 to 4, the present invention relates to a heat preservation type hot pepper water tear gas bomb, which comprises an outer shell 11, an inner shell 22, a piston body 31 and an ejection assembly. The outer casing 11 and the inner casing 22 are both cylindrical structures, i.e., wall structures through which both upper and lower end surfaces penetrate, and are generally provided in a cylindrical shape. One end of the shell 11 is opened and contracted to form a jet orifice 12 which is usually smooth and excessive, so that the kinetic energy loss in the pepper water spraying process is effectively reduced. The inner shell 22 is located inside the outer shell 11, a heat preservation layer 21 is arranged between the outer shell 11 and the inner shell 22, and the heat preservation layer 21 is used for preserving heat of the inner shell 22 and materials in the inner shell 22. The insulating layer 21 is made of a material having a relatively good insulating effect, and should have a small thickness in order to ensure a compact overall structure. The end of the inner shell 22 near the ejection port 12 is closed by a thin sheet 24, and the thin sheet 24 is generally thin and is easily broken by pressure. And the thickness of the middle portion should be relatively small from the periphery in order to ensure that the pressure can be broken from the middle portion to avoid the edge from being broken to block the ejection opening 12. The piston body 31 is positioned at one end of the inner shell 22 far away from the jet orifice 12, the thin sheet 24, the inner shell 22 and the piston body 31 enclose a closed material cavity 23, and the material cavity 23 is filled with pepper water. The peripheral wall of the piston body 31 abuts the inner wall of the inner shell 22 and the piston body 31 can slide relative to the inner wall, creating a similar effect to a piston in a syringe. The pepper water in the material cavity 23 is generally natural pepper water, so that the injury to a human body is effectively reduced while the effect is ensured. The ejection assembly, which is mounted at the end of the outer housing 11 remote from the ejection opening 12 and which acts upon the piston body 31 after activation to push the piston body 31 forward along the inner housing 22, may be simply similar to the bottom structure of a conventional ammunition but with a correspondingly lower charge. The ejection assembly is provided with a connected gunpowder bin 44 and a primer 41, the primer 41 is stimulated to fire by inputting mechanical energy or electric energy, the gunpowder bin 44 faces the piston body 31, and high-pressure gas rushes to the piston body 31 after gunpowder explodes and drives the piston body 31 to move. This tear-gas shells mainly relies on gun machinery to arouse and launches the subassembly, and then urges the hot pepper water to spray out.

In a preferred embodiment, a grid 13 is provided between the ejection opening 12 and the sheet 24, and the grid 13 is provided with a raised top piece and a plurality of slots, the top piece abutting against the sheet 24. The ejection assembly drives the piston body 31 to move after being excited, the chili water in the material cavity 23 is pressed to extrude the thin sheet 24, and the thin sheet 24 props against the ejector block and is burst by the ejector block, so that the chili water is ejected. The sheet 24 is effectively ensured to be broken from the middle without breaking the whole piece to cause blockage. And the thickness of the thin sheet 24 can be designed to be larger, so that the thin sheet 24 with smaller thickness is prevented from being easy to crack and leak.

In a preferred embodiment, a groove 33 is formed in one side of the piston body 31 close to the explosive chamber 44, the groove 33 is communicated with the explosive chamber 44, and the groove 33 can sufficiently receive high-pressure gas after the explosive chamber 44 explodes, so that the high-pressure gas is sufficiently driven. Meanwhile, the wall surface of the groove 33 can be expanded to the periphery while bearing high-pressure gas, so that the wall surface of the piston body 31 is more tightly attached to the inner wall of the inner shell 22, the self-locking effect is further realized, and the chili water is effectively prevented from leaking.

In the preferred embodiment, the ejection assembly includes a propellant cup 42 and a strike plate 43. One end of the outer shell 11 far away from the jet orifice 12 is contracted to form a convex step, the abutting plate 43 is positioned in the outer shell 11 and abuts against the convex step and the inner shell 22 through the side surface, wherein the circumferential wall of the abutting plate 43 is provided with an annular convex block which is used for abutting against the convex step and the inner shell 22 respectively. The gunpowder cup 42 comprises a gunpowder bin 44 and a cup edge positioned on the end face, a through cavity penetrating through the upper end face and the lower end face is arranged in the supporting plate 43, and the gunpowder bin 44 is positioned in the through cavity. The outer wall of the gunpowder bin 44 can be installed on the inner wall of the through cavity through threads, the gunpowder cup 42 can be installed after the gunpowder cup is installed by the aid of the supporting plate 43, and the stability of the overall structure cannot be affected by disassembling the gunpowder cup 42. Two end faces of the abutting plate 43 abut against the piston body 31 and the cup edge respectively, so that the structure is compact. Usually, the ends of the gunpowder cup 42 and the resisting plate 43 will shrink inward to some extent, so that the high-pressure gas can be effectively collected to impact the piston body 31. Preferably, a cover body 45 fixed on the outer wall is further arranged on one end of the shell 11 far away from the jet orifice 12, a mounting hole is arranged in the middle of the cover body 45, and the cup edge of the gunpowder cup 42 is connected into the mounting hole through threads.

In a preferred embodiment, the injection port 12 is provided with an end cap for closing the injection port 12, and the end cap is screwed to the outer wall of the housing 11. The end cover can play a good protection role when not in use, avoids the leakage of chili water caused by that foreign matters enter the jet orifice 12 to puncture the sheet 24 when not in use, and can also enhance the heat preservation effect.

In this embodiment, the outer walls of the outer shell 11 and the inner shell 22 of the heat-insulating type hot pepper water tear gas bomb have a circular cross-sectional shape. And the heat-insulating layer 21 and the thin sheet 24 are both made of aluminum foil paper, so that the structure can be compact. An annular groove is provided on the piston body 31, and a seal ring 32 is provided in the annular groove to improve sealability and prevent the seal ring 32 from being disengaged. Preferably, the number of annular grooves and sealing rings 32 is 2.
