Detonation producing toy device utilizing air pressure

Abstract

A detonation producing toy device utilizes air pressure. The device has a gun body in which an air pump, a seal body and a rolling mechanism are disposed. The air pump is integrated with the seal body. An elongate strip of rubber film from the rolling mechanism is pressed between the seal body and a gunpoint which is at one end of the gun body. As a trigger of the device is fired, compressed air from the pump causes the film to expand outwards till it bursts, and at the same time detonation is produced. This interesting device is easy to operate, with simple structure, great safety and vivid vocal effect.

1 . A kind of detonation production toy device, its character is that it includes: gun body  1 , power switch  2 , rubber film  3 , trigger mechanism  4 , air pump  5 , reposition spring  6 , seal body  7 , gunpoint  8 , rolling mechanism  9 , power  10 .  
   
   
       2 . Said as in  claim 1 , the detonation production toy device, its character is: the rubber film  3  is made of latex or synthetic rubber, the thickness is less than 1 mm, formed into strip shape, and also can be compounded with plastic film, and it is set between seal body  7  and gunpoint  8 , it is moved to gunpoint  8  by seal body  7 , fastens the rubber film  3  into seal part.  
   
   
       3 . Said as in  claim 1 , the detonation production toy device, its character is: upside of the trigger mechanism  4  is a cam shape, and pushes the air pump  5  and seal body  7  to gunpoint  6  by lever force, and recover under the action of reposition spring.  
   
   
       4 . Said as in  claim 1 , the detonation production toy device, its character is: rolling mechanism  9  is made of driver wheel, driven wheel and transmission mechanism, rubber film  3  rolls on the driven wheel first, then connected to driver wheel, with the rotation of driver wheel, rolls the detonated rubber film onto the driver wheel in succession, and sends the new rubber film to the gunpoint at the same time.
