fig. 2 is a sectional view a-a of fig. 1.

In the figure: 1. the device comprises a base, 2 parts of an electric explosion tube, 3 parts of a medicine box, 31 parts of a supporting seat, 32 parts of a redirection tube and 33 parts of a filtering hole; 4, a shell, 5, a rupture disk, 6, a shell, 61, a first shell, 62, a second shell, 621, a groove, 622 and an exhaust hole.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

Example 1:

as shown in fig. 1 and 2, the novel generator comprises a housing 4. The shell 4 is provided with a base 1, an electric detonator 2, a medicine box 3 and a rupture disk 5 in sequence from front to back. The shell 6 is connected behind the rupture disk 5. The medicine box 3 is provided with a filtering hole 33, and a redirection pipe 32 is arranged between the medicine box 3 and the inner surface of the shell 4. The base 1 is internally provided with a vertical plate with a hole, and the electric detonator 2 is sleeved with the vertical plate. The front end of the medicine box 3 is a cylinder and is a spherical surface, and the filtering holes 33 are positioned on the spherical surface. The bend 32 is a circular arc surface, one end of the bend 32 is connected with the medicine box 3, and the other end is connected with the shell 4. The central axes of the redirecting tube 32, the housing 4 and the medicine box 3 are overlapped. A supporting seat 31 for connecting the medicine box 3 and the shell 4 is arranged between the medicine box 3 and the inner surface of the shell 4. The support seat 31 is in front of the redirecting tube 32. The rupture disk 5 is located at the end of the housing 4 and is pressed against the casing 6. The housing 6 comprises a first disk-shaped housing 61 and a second circular-tube-shaped housing 62, the first housing 61 is connected with the second housing 62, and the cross section of the housing 6 is T-shaped. The diameter of the inner surface of the joint of the first shell 61 and the second shell 62 is smaller than that of the inner surfaces of the first shell 61 and the second shell 62. The side surface of the second casing 62 is provided with a groove 621. The side of the second housing 62 is provided with a plurality of air vents 622, and the air vents 622 are located behind the grooves 621.

The working process is as follows: when the housing 4 receives a collision impact signal, the squib 2 ignites the transfer charge in the cartridge 3. Not only gas but also a part of the residue is generated in the cartridge 3, and the residue is filtered out through the filter holes 33 in the cartridge 3. Due to the guidance of the redirecting tube 32, the gas moves through the filter openings 33 in the direction of the rupture disk 5. When the gas pressure exceeds the burst pressure of the burst membrane 5, the burst membrane 5 ruptures and gas enters the housing 6. Because the diameter of the inner surface of the joint of the first shell 61 and the second shell 62 is smaller than the diameter of the inner surface of the first shell 61 and the diameter of the inner surface of the second shell 62, when the gas moves from the first shell 61 to the second shell 62, the gas can rapidly enter the second shell 62. And through the vent hole on the side surface of the second shell 62, the gas enters the safety air bag, and the safety air bag is opened to ensure the safety of the human body.
