Abstract

The invention relates to an electric fin and a water transport tool, and the electric fin comprises a housing which extends in a first direction and is provided with a water inlet cavity; a propellerand a flow guide part which are sequentially arranged in the first direction, wherein the propeller is located in the water inlet cavity, at least part of the flow guide part is located in the water inlet cavity, and water flow in the water inlet cavity flows out of the flow guide part. The propeller is provided with a propeller shaft and a plurality of blades, the propeller shaft extends in the first direction, and the blades are arranged on the propeller shaft in the circumferential direction; the flow guide part is provided with a flow guide shaft and a plurality of flow guide pieces, the flow guide shaft extends in the first direction, and the flow guide pieces are arranged on the flow guide shaft in the circumferential direction; the size of the projection of the outer contour definedby the propeller shaft and the flow guide shaft in the second direction in the third direction is gradually reduced in the fourth direction. The electric fin is sufficient in power and good in guidance quality.

Description

technical field [0001] The invention relates to the technical field of water sports equipment, in particular to an electric fish fin and a water vehicle. Background technique [0002] The bottoms of existing surfboards, SUP or inflatable boats and other water vehicles usually need to install one or more fins to enhance the water splitting effect and the flexibility of turning when the surfboard is running. [0003] For example, the Chinese patent with the publication number CN109956015A discloses a booster propeller for water sports, including: at least one support plate and more than one booster main body corresponding to each support plate; A first card slot is provided, and the front of each supporting plate is buckled on the corresponding first card slot and fixed by the first card pin; the back of the supporting plate is provided with a second card slot for fixing the corresponding booster main body, The main body of the power booster is buckled on the corresponding se...
