    摘要: 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.

    摘要: The single-jointed underwater robot fish includes a casing, a main board cabin, a motion control cabin and a battery cabin. The outer contour of the casing is a bionic fish shape, one end is a front casing, and the other end is a bionic fishtail structure. The front end of the main board cabin is affixed to the inner side of the front casing, a lens group, an eccentric anti-shake mechanism and a main PCB (printed circuit board) are set in the main board cabin. The motion control cabin is connected to the rear end of the main board cabin. A triaxial linkage device and a transmission device are set in the motion control cabin. The battery cabin is located below the motion control cabin.

    摘要: A handheld underwater aircraft includes a battery compartment (12) and propellers. There are at least two propellers, which are symmetrically distributed on both sides of the battery compartment (12), and are connected to the battery compartment (12). A special design with axes of the propellers being unparallel with an axis of the battery compartment (12) is adopted, and unparallel included angles make component forces generated by the various propellers in a direction of motion of a non-underwater aircraft offset each other, and enable the underwater aircraft to maintain balanced and forward-forward motion. The design with the axes of the propellers being unparallel with the axis of the battery compartment (12) leads to a little power loss, but avoids a larger power loss caused by the impact of water on the human body, thereby comprehensively improving the thrust of the underwater aircraft in use.
