Abstract:
1. A propeller driven surfing device, comprising: an elongated body having front and rear ends opposite to each other along a longitudinal axis, and a tubular wall extending in a longitudinal direction parallel to the longitudinal axis to interconnect said front and rear ends so as to define an accommodation chamber therein; a drive motor disposed in said accommodation chamber; a power supply disposed in said accommodation chamber, and operationally coupled to said drive motor; a propeller which is driven by said drive motor, and which is disposed outwardly of said elongated body and rearwardly of said rear end; a shell member including a front surrounding segment which surrounds and which is spaced apart from said tubular wall to define a passageway therebetween, and a rear surrounding segment which extends rearwardly from said front surrounding segment in the longitudinal direction and which terminates at a distal end that is disposed rearwardly of said propeller and that is spaced apart from said propeller in the longitudinal direction, said front surrounding segment and said distal end respectively defining a water intake port and a water outlet port which are disposed upstream and downstream of said passageway, respectively, such that water flows from said intake port and out of said outlet port through said passageway; and a control member which is disposed in said accommodation chamber and which is electrically coupled to said drive motor and said power supply so as to control operation of said drive motor.
