[0021] Please refer to Figs. 1-4 , example one:

[0022] In the embodiment of the present application, the copper sheet and steel sheet type blasting mechanism of the embodiment comprises an upper cover 1, a lower cover 2, a sintered filter element 4, a pull rod 6, a steel sleeve 7, a push rod 13 and the like. One end of the upper cover 1 is provided with the lower cover 2, and the two are connected through threads. The inner part of the upper cover 1 and the lower cover 2 is jointly provided with the pull rod 6, the copper sintered filter element 4 is fixedly connected to the inner wall of the top hole of the pull rod 6, and is used for filtering impurities in the gas. The inner wall of the end of the lower cover 2 away from the upper cover 1 is provided with the push rod 13, one end of the push rod 13 close to the pull rod 6 is fixedly connected with the spring 11, and the other end of the spring 11 close to the pull rod 6 is fixedly connected with the side wall of the pull rod 6. The inner wall of the lower cover 2 between the pull rod 6 and the push rod 13 is fixedly connected with the steel sleeve 7.

[0023] In the embodiment, the pull rod 6 is movably connected with the steel sleeve 7 at one end close to the steel sleeve 7, and an O-ring 9 is fixedly connected to the outer wall of the one end of the pull rod 6 close to the steel sleeve 7. The outer wall of the steel sleeve 7 is fixedly connected with a buffer O-ring 8, so as to reduce the friction and abrasion between the steel sleeve 7 and other components, and to realize the movable and air-tight function between the steel sleeve 7 and the inner wall of the lower cover 2. In addition, a sealing ring 5 is fixedly connected to the outer wall of the sintered filter element 4 on the pull rod 6, so as to improve the sealing performance.

[0024] In the initial state (i.e. the inflation state) of the mechanism, the sealing relationship between the components is as follows: the O-ring 12 of the steel sleeve 7 and the inner wall of the air cavity in the lower cover 2 are in close contact and can be air-tight; the connecting O-ring 9 on the pull rod 6 and the inner wall of the steel sleeve 7 are in close contact and can be air-tight; the surface of the sealing ring 5 and the surface of the V-shaped groove on the pull rod 6 are in close contact and have a sealing effect, and the sealing ring 5 on the pull rod 6 and the inner wall of the blasting hole of the upper cover 1 are in close contact; the connection between the upper cover 1 and the lower cover 2 is also provided with an O-ring to ensure air-tightness. These sealing relationships ensure that the mechanism will not leak air during inflation.

[0025] When blasting is needed, the spring 11 pushes the pull rod 6 to move towards the top of the mechanism, and the push rod 13 moves towards the tail. During the movement, the steel ball 10 on the pull rod 6 is pushed along the outer wall of the push rod 13 to the circular arc groove inside the steel sleeve 7 and is limited. At this time, the mechanism returns to the initial state.

[0026] Embodiment two:

[0027] The embodiment is basically the same as embodiment one, except that a guide block 14 is arranged on the outer wall between the sintered filter element 4 and the push rod 13. The outer wall of the guide block 14 is fixedly connected with the inner wall of the upper cover 1, and the pull rod 4 is movably connected with the guide block 14. This design makes the pull rod 6 more stable during movement, reduces the friction and abrasion caused by shaking, and also makes the head of the pull rod 6 and the O-ring 5 part.

[0028] The working principle of the utility model is as follows: in the inflation stage, the gas enters the sintered filter element 4 for filtration through the inflation jig set, and then flows into the mechanism gas storage part through the air guide hole of the pull rod 6. Since the O-ring has a recoverable elastic deformation within a certain range, the gas can lift the O-ring after flowing through the guide hole and enter the inside of the mechanism. At this time, the sealing relationship between the components ensures that the gas will not leak out of the mechanism.

[0029] In the explosion stage, the spring 11 is compressed and the pull rod 6 is pushed to move to the tail of the mechanism by pushing the push rod 13. During the movement, the steel ball 10 on the pull rod 6 is pushed to the circular arc groove inside the steel sleeve 7 and is limited. At this time, continue to push the push rod 13 to make the steel ball 10 out of the circular arc groove and make the pull rod 6 quickly retreat under the push of the gas pressure. During this process, the No. 16 O-ring is separated from the explosion hole of the upper cover of the No. 2 gas chamber, causing the high-pressure gas stored in the mechanism to be instantly blown out through the explosion hole. After the explosion is completed, the spring 11 will lift the push rod 13 and the pull rod 6 by the elastic force and reset to the initial state to wait for the next use.
