Abstract

Disclosed is a compact egg-shaped propeller, including an outer shell, an inner shell, and a driving motor unit arranged in the inner shell. The outer shell is detachably connected to the inner shell; the outer shell is egg-shaped; the outer shell is provided with a front cover at a top of the driving motor unit; the outer shell is provided with a jet orifice at a tail portion of the driving motor unit; blades are connected to one side of the driving motor unit close to the front cover; the driving motor unit is connected to a main control compartment; foldable handles are connected to a left side and right side of the main control compartment respectively; and the foldable handles are movably connected to the inner shell. By means of the layout, the gravity center is centered, the structure is compact and simple, and the appearance is simple and beautiful; the blades and the motor are designed in front, and the semi-circular front cover prevents debris and hands from entering; a battery indicator can display current remaining power to a user; a buoyancy block ensures that the whole device does not sink down after a user loosens the hands in water, facilitating search; and when the device is not in use, the handles can be folded, thereby facilitating storage and carrying.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A compact egg-shaped propeller, comprising an outer shell ( 1 ), an inner shell ( 5 ), and a driving motor unit ( 2 ) arranged in the inner shell ( 5 ), wherein the outer shell ( 1 ) is detachably connected to the inner shell ( 5 ); the outer shell ( 1 ) is egg-shaped; the outer shell ( 1 ) is provided with a front cover ( 1 - 1 ) at a top of the driving motor unit ( 2 ); the outer shell ( 1 ) is provided with a jet orifice ( 1 - 2 ) at a tail portion of the driving motor unit ( 2 ); blades ( 2 - 1 ) are connected to one side of the driving motor unit ( 2 ) close to the front cover ( 1 - 1 ); the driving motor unit ( 2 ) is connected to a main control compartment ( 3 ); foldable handles ( 3 - 1 ) are connected to a left side and right side of the main control compartment ( 3 ) respectively; and the foldable handles ( 3 - 1 ) are movably connected to the inner shell ( 5 ). 
     
     
         2 . The compact egg-shaped propeller according to  claim 1 , wherein the outer shell ( 1 ) is provided with a gap matched with the folding handles ( 3 - 1 ); and a handle lock catch ( 1 - 3 ) for fixing the folding handles ( 3 - 1 ) is arranged at a tail end of the gap. 
     
     
         3 . The compact egg-shaped propeller according to  claim 1 , wherein start buttons are arranged on the folding handles ( 3 - 1 ). 
     
     
         4 . The compact egg-shaped propeller according to  claim 1 , wherein a battery ( 2 - 2 ) is arranged in the driving motor unit ( 2 ); the battery ( 2 - 2 ) is connected with a motor, and the blades ( 2 - 1 ) are connected to the motor. 
     
     
         5 . The compact egg-shaped propeller according to  claim 1 , wherein the driving motor unit ( 2 ) is provided with a supporting device ( 2 - 3 ) inside the inner shell ( 5 ). 
     
     
         6 . The compact egg-shaped propeller according to  claim 1 , wherein the main control compartment ( 3 ) is fixedly mounted on the inner shell ( 5 ); and an upper part of the main control component ( 3 ) is provided with a battery indicator ( 3 - 2 ). 
     
     
         7 . The compact egg-shaped propeller according to  claim 6 , wherein buoyancy blocks ( 3 - 3 ) are mounted on the left and right sides of the main control compartment ( 3 ); and the buoyancy blocks ( 3 - 3 ) are fixedly mounted on the inner shell ( 5 ).
