Benefits of technology

[0010]In summary, the electrical forward moving assistant apparatus can be easily attached and detached onto the diver's equipment, such as scuba tank or BCD, and thus does not require hand-held to operate. Its compact profile base

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.

Description

[0001]This application claims the benefit of priority based on Taiwan Patent Application No 104201469, filed on Jan. 30, 2015, the contents of which are incorporated herein by reference in their entirety.CROSS-REFERENCES TO RELATED APPLICATIONS[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]This invention is regarding an electrical forward-moving assist apparatus. More precisely speaking, this invention is regarding an ultra-compact, low drag in water, hands-free and easy-to-install electrical forward-moving assist apparatus.[0005]2. Descriptions of the Related Art[0006]In prior art, diver propulsion vehicle requires user to hold the vehicle by hand to operate. This inconvenience greatly limited user's ability to perform other function. Also, during use underwater, a hand-held type vehicle could drift away unnoticed if left on the sea floor beside diver.[0007]For this reason, prior art as depicted in FIG. 1, the diver propulsion device 1 utilizes...
