Problems solved by technology

However, these three types of air guns were invented by Americans and French. If we want to use them, we must import them. The technology and equipment are controlled by others, which is not conducive to the development of offshore oil exploration. We have such a large population and such a wide sea area in China. self-designed air gun

Embodiment 1

[0027] Such as figure 1 A sound generating device shown includes a nozzle 101 , a piston 102 , and an air cylinder 103 . The gun head 101 is connected to the upper end of the air cylinder 103 by thread, and the gun head 101 is provided with a connection hole 104, which can be connected with the air pipe. 103 is divided into an upper air chamber 105 and a lower air chamber 111. There is a vent hole 106 in the center of the piston, and a rubber sleeve 110 is set at the outlet of the vent hole 106. There is a protrusion 109 inside the air cylinder, which can prevent the piston 102 from moving downward. An explosion opening 108 is opened above the protrusion 109 .

[0028] The compressed air enters the upper air chamber 105 of the air cylinder 103 through the connection hole 104 on the gun head 101, and the compressed air in the upper air chamber 105 pushes the piston 102 to slide down until it is pressed against the protrusion 109 of the air cylinder 103. At this time, the seal...

Embodiment 2

[0030] Such as figure 2 A kind of sound generating device shown comprises gun head 201, piston 202 and air cylinder 203, and gun head 201 is connected to the upper end of air cylinder 203 by the mode of screw thread, has connecting hole 204 on the gun head 201, can be connected with trachea, and piston 202 Inside the air cylinder 203, the thick end of the piston 202 is covered with a sealing ring 207, and the air cylinder 203 is divided into an upper air chamber 205 and a lower air chamber 209. There is a vent hole 206 in the center of the piston 202, and a vent hole 206 is provided at the outlet of the vent hole 206. The rubber sleeve 208 acts as a one-way valve. There is an explosion opening 212 in the center of the bottom of the air cylinder 203. The protrusion at the bottom of the piston 202 extends to the explosion opening 212. A sealing ring 210 is set at the contact with the explosion opening 212 to seal the explosion opening 212 and extend to the explosion opening 212...

Embodiment 3

[0034] Such as image 3 A sound generating device shown includes a solenoid valve 301 , a nozzle 305 , a piston 308 , and an air cylinder 12 . The spool 302 of the solenoid valve 301 seals the air hole on the left side by the elastic force of the spring when it is not powered on. The piston 308 divides the air cylinder 312 into an upper air chamber 306 and a lower air chamber 311. The piston 308 has an air inlet 307 Connect the upper and lower air chambers, the gun head 305 is provided with an air intake hole 304 and an air expansion adjustment air chamber 303, the air intake hole 304 communicates the solenoid valve 301 with the upper air chamber 306, the gas expansion adjustment air chamber 303 and the ignition air hole 310 In communication, the air cylinder 312 is provided with an explosion port 309.

[0035]The high-pressure gas flows in through the electromagnetic valve 301, then flows into the upper chamber 306 through the air hole 304, pushes the piston 308 to slide dow...

Abstract

The invention provides a sound producing device capable of producing sound by using air. The sound producing device comprises an air cylinder, a piston and a gun head. The piston is sleeved with a planar sealing ring which can prevent air circulation of an upper air chamber and a lower air chamber of the air cylinder. The cylinder wall portion, above a protruding table, of the air cylinder is uniformly provided with explosion openings. When the piston is attached to the protruding table, the sealing ring on the piston is right pressed against the inner sides of the explosion openings to seal the explosion openings. The device is wide in application range and can be applied to flammable places such as coal mines and oil and gas fields; the device can even be used in water; the device has economic value, social value and cultural value; selling air firecrackers can bring economic income for employees, enterprises and the government, so that the economic value is obvious; the sound producing device is a safe and environmentally-friendly firecracker, and pollution can be reduced greatly if the device replaces an explosive firecracker, so that the sound producing device is of great social importance; the sound producing device enables people to continue and develop the traditional firecracker setting-off culture without polluting the environment.

Description

technical field [0001] The invention belongs to a sound generating device, especially firecrackers and air guns, but not limited to these two. Background technique [0002] Firecrackers have a long history. Setting off firecrackers has become an important part of the ceremony held by the Chinese nation to celebrate the grand ceremony. This ceremony supports the common beliefs and dreams of Chinese people all over the world, and has become the traditional culture of the Chinese nation. [0003] However, most of the traditional explosive firecrackers are currently on the market. During production or transportation, a large number of firecrackers are piled up together. Once the explosion is very harmful, it not only seriously pollutes the environment when it is set off, but also may cause injuries and fires. Since traditional firecrackers are disposable consumables and cannot be reused, a large amount of garbage is left after setting off, which also causes a waste of resources....
