Problems solved by technology

This inconvenience greatly limited user's ability to perform other function.
Even though diver propulsion device 1 in FIG. 1 can be operated hands-free, but its profile increased drag in water, and thus become user's burden when the vehicle lost its propulsion power due to low battery or malfunction.
Furthermore, the structure of diver propulsion device 1 is exposed and thus can be entangled by objects or cause damage to environment underwat...

Abstract

An electrical forward-moving assistant apparatus comprised of a housing, a motor, a battery unit, a propeller, a housing mounting fixture and a battery mounting fixture. The housing forms a watertight chamber. The housing mounting fixture is installed onto the housing to position the housing on one end of a cylinder body. The motor is installed inside the watertight chamber and connected to the propeller by a shaft which extends through the housing to provide thrust. The battery unit mounted on the cylinder body by the battery mounting fixture is connected to the motor via an electrical wire.
