Abstract:
1. An electrical pump adapted for use with a piston rod in a nozzle assembly, the electrical pump comprising: a base; a motor; a motor bracket securely connected to the motor; a blade assembly rotatably mounted on the motor bracket to be driven by the motor via a motor shaft extending out of the motor; an electromagnetic valve board with an electromagnetic valve actuator 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 so as to form an inlet and an outlet, wherein a Z-shaped push rod is operably connected to the electromagnetic valve actuator so as to be driven by the electromagnetic valve actuator and to drive a piston rod in a nozzle assembly to move accordingly, in a situation where an object having therein the nozzle assembly is to be inflated, the inlet is for suction of air from ambient air and the outlet is structured for alignment with the nozzle assembly of the object so as to blow the air into the object and where the object is to be deflated, the inlet is structured for alignment with the nozzle assembly of the object for sucking the air inside the object and the outlet is for venting the air sucked in via the inlet, thereby allowing air from the electrical pump to be pumped into or away from the object to be inflated/deflated when the motor is running.
