Push rod in an electrical pump adapted for use with a piston rod in an air nozzle

Abstract

An electrical pump adapted for use with a piston rod in an air nozzle has an electromagnetic valve board with an electromagnetic valve thereon. A Z-shaped push rod is provided to be adapted to be driven by the electromagnetic valve so as to drive the piston rod to move accordingly. The movement of the Z-shaped push rod allows air from the electrical pump to be pumped into an object to be inflated when the motor is running, and air inside the object to flow out of the object to be deflated when the motor is not running.

What is claimed is:  
     
         1 . In an electrical pump adapted for use with a piston rod in an air nozzle, the electrical pump provided with a base, a motor, a motor bracket securely connected to the motor, a blade assembly rotatably mounted on the motor bracket, an electromagnetic valve board with an electromagnetic valve thereon, a cover securely connected to the electromagnetic valve board and the base to sandwich therebetween the motor, the motor bracket, the blade assembly and the electromagnetic valve board, wherein the improvement comprises: 
 a Z-shaped push rod adapted to be driven by the electromagnetic valve so as to drive the piston rod to move accordingly,    thereby allowing air from the electrical pump to be pumped into an object to be inflated when the motor is running, and    allowing air inside the object to flow out of the object to be deflated when the motor is not running.
