A compact egg-shaped propeller includes an outer casing 1, a driving motor group 2 and a main control cabin 3.

The various components of the propeller are arranged symmetrically along the axis. The battery 2-2 and the motor are arranged back and forth on the axis. The front cover 1-1 will affect the efficiency of pushing water. Install the front cover 1- in front of the blade 2-1. 1 The purpose is to put sundries and human hands into it, because it is arc-shaped, in some places, even if the hand is thin enough to reach in, it can't touch the blade 2-1.

The battery 2-2 is set at the rear so that people can take out the battery from the rear.

The folding handle 3-1 of the thruster is operated with both hands. The folding handle 3-1 is provided with a switch button. Pressing the switch at the same time will give a signal to the main control compartment 3, which is connected to the battery 2-2 At this time, the main control cabin 3 will supply power and electrical signals to the motor, which will cause the motor to rotate, which will drive the blades 3-1 to also rotate. After the water is sucked in from the front cover 1-1, it will flow into the inner flow channel 4 after pressurization. , And then pass through the supporting device 2-3, rectify and eject from the jet port 1-1 at the tail to generate thrust.

The folding handle 5 held by both hands drives the human body to move forward in the water. The battery indicator 3-2 can show the user the current battery level. The buoyancy block 3-3 ensures that the entire device will not sink after the user loosens his hands in the water. Floating on the water, easy to find.

In specific use, according to the compact egg-shaped propeller of the present invention, the folding handles are held by hand, the two folding handles bounce up, the start button is pressed, and the battery starts to supply power. At this time, the water flows through the front cover and is The leaf exerts pressure and is supported by the support plate, and finally ejects from the end of the inner flow channel to form a forward thrust. The shape of the egg is also more affinity.

After use, fold the handle and lock it with the handle lock. At this time, the whole machine becomes an egg shape, and the buoyancy block provides enough buoyancy for the propeller to float out of the water.

In summary, with the above technical solution of the present invention, through this layout, the center of gravity is centered, the structure is compact and simple, and the appearance is simple and beautiful; the blade and the motor are designed in the front, and the semicircular front cover prevents the entry of debris and human hands; the battery It is set at the rear to facilitate the user to take out the battery from the back; the battery indicator can show the user the current battery level; the buoyancy block guarantees that the entire device will not sink after the user releases his hands in the water, and floats on the water, which is convenient to find; the device When not in use, the handle can be folded for convenient storage and carrying.
