TW201439491A - Pressure difference type bullet driving structure of toy gun - Google Patents

Abstract

The present invention relates to a pressure difference type bullet driving structure of a toy gun, which functions to sequentially drive BB bullets. The pressure difference type bullet driving structure comprises an expansion device, a sleeve device slidably received in the expansion device, and a pneumatic module arranged at one side of the expansion device. The expansion device has a guide post penetrating through the sleeve device. The guide post has a side wall that is provided with at least one gas inlet hole extending in a direction away from the pneumatic module. The gas inlet hole is selectively blocked by the sleeve device. When the pneumatic module is actuated to generate high pressure gas, the high pressure gas flows through the expansion device to push the sleeve device so as to make it shifted to drive the BB bullets. When the sleeve device is shifted to expose the gas inlet hole, the high pressure gas will be injected into the gas inlet hole to shoot the BB bullet. As such, practical efficacies of lowering cost, reducing the use of interior space, and reducing malfunctions, being easy to assemble and disassemble, and reducing the loading of a power device can be achieved.
