Abstract

The invention discloses an external power generating air cylinder for a cymbal type piezoelectric element and solves the problems that an existing pneumatic piezoelectric power generating device is complex in structure, low in energy utilizing rate and high in noise. The external power generating air cylinder comprises an air cylinder body and a piezoelectric power generating device; the power generating device is connected with the rear end of the air cylinder body through a thread pair; and the piezoelectric power generating device is composed of a cavity end cover, a piston, a power generating assembly and a cavity. The power generating assembly is extruded by the piston under the air impact of compressed air and the action of air pressure, the cymbal type piezoelectric element can mechanically deform and return in the lower pressured, and accordingly power can be generated based on the piezoelectric effect. The external power generating air cylinder has the beneficial effects of being simple in structure, high in energy utilizing rate, low in noise and low in cost. The generated power can be collected through a rectifying energy storing circuit and supplied for nodes of internet of things. The external power generating air cylinder has wide application prospect in the technical field of pneumatics.
