Definitions

  • the present disclosure relates to the technical field of propellers, specifically to a compact egg-shaped propeller.
  • the present disclosure provides a compact egg-shaped propeller, which can overcome the above shortcomings in the prior art.
  • a compact egg-shaped propeller includes 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.
  • the outer shell is provided with a gap matched with the folding handles; and a handle lock catch for fixing the folding handles is arranged at a tail end of the gap.
  • start buttons are arranged on the folding handles.
  • a battery is arranged in the driving motor unit; the battery is connected with a motor; and the blades are connected to the motor.
  • the driving motor unit is provided with a supporting device inside the inner shell.
  • main control compartment is fixedly mounted on the inner shell; and an upper part of the main control component is provided with a battery indicator.
  • buoyancy blocks are mounted on the left and right sides of the main control compartment; and the buoyancy blocks are fixedly mounted on the inner shell.
  • 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.
  • the battery is arranged at the back, facilitating a user to take out the battery from the back.
  • the battery indicator can display current remaining power to the user.
  • the buoyancy blocks ensure that the whole device does not sink down and will float on the water after the user loosens the hands in water, facilitating search. When the device is not in use, the handles can be folded, thereby facilitating storage and carrying.
  • 1 outer shell
  • 1-1 front cover
  • 1-2 jet orifice
  • 1-3 handle lock catch
  • 2 driving motor unit
  • 2-1 blade
  • 2-2 battery
  • 2-3 supporting device
  • 3 main control compartment
  • 3-1 folding handle
  • 3-2 battery indicator
  • 3-3 buoyancy block
  • 4 inner flowing channel
  • 5 inner shell.
  • a compact egg-shaped propeller includes an outer shell 1, an inner shell 5, and a driving motor unit 2 arranged in the inner shell 5.
  • 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.
  • the foldable handles 3-1 are movably connected to the inner shell 5.
  • 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.
  • start buttons are arranged on the folding handles 3-1.
  • 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.
  • the driving motor unit 2 is provided with a supporting device 2-3 inside the inner shell 5.
  • 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.
  • 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.
  • a compact egg-shaped propeller includes an outer shell 1, a driving motor unit 2 and a main control compartment 3.
  • All the components of the propeller are all symmetrically arranged along an axial direction.
  • a battery 2-2 and a motor are in front and back arrangement at an axis.
  • a front cover 1-1 will affect the water pushing efficiency. Adding the front cover 1-1 in front of blades 2-1 is to prevent debris and hands from entering. Since the front cover is arc-shaped, a user cannot touch the blades 2-1 even if the hands are thin enough to get in from certain positions.
  • the battery 2-2 is arranged at the back, which facilitates the user to take out the battery from the back.
  • the folding handles 3-1 of the propeller are held by two hands for operation. ON/OFF buttons are arranged on the folding handles 3-1. A signal will be sent to the main control compartment 3 if the ON/OFF buttons are pressed at the same time.
  • the main control compartment 3 is connected to the battery 2-2 and the motor. At this time, the main control compartment 3 will supply power and an electrical signal to the motor to make the motor rotate to drive the blades 3-1 to rotate as well. After water is sucked from the front cover 1-1 and then pressurized, the water flows into an inner flowing channel 4. The water is then straightened through a supporting device 2-3 and is jetted from the jet orifice 1-1 at the tail, thus generating a thrust.
  • the folding handles 3-1 held by the two hands drive the user to move forwards in water.
  • the battery indicator 3-2 can display the current battery power to the user.
  • the buoyancy blocks 3-3 ensure that the whole device does not sink down and will float on the water after the user loosens the hands in water, facilitating search.
  • the folding handles are held by the hands.
  • the two folding handles pop up, and the start buttons are triggered.
  • the battery starts to supply power.
  • water flows through the front cover is pressurized by the blades and supported by a supporting plate, and is finally jetted out from the tail of the inner flowing channel to generate a forward thrust.
  • the egg model is also friendly.
  • the buoyancy blocks provide enough buoyancy to the propeller in water, so that the propeller floats out of the water.
  • 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.
  • the battery is arranged at the back, facilitating a user to take out the battery from the back.
  • the battery indicator can display current remaining power to the user.
  • the buoyancy blocks ensure that the whole device does not sink down and will float on the water after the user loosens the hands in water, facilitating search. When the device is not in use, the handles can be folded, thereby facilitating storage and carrying.
