TECHNICAL FIELD
The present disclosure relates to the technical fields of underwater propellers, electric assist apparatuses for hydrofoil boards, and electric assist electric assist for diving, and particularly relates to a propeller.
BACKGROUND
Underwater propellers, electric assist apparatuses for hydrofoil boards, and electric assist electric assist for diving in the prior art have the following disadvantages:
- a. Existing handheld underwater propellers, non-powered hydrofoil board boosters, and diving assist devices can only be used in single scenarios, and usage scenarios cannot be easily and flexibly switched. Handheld underwater propellers cannot be used together with other sports equipment, while hydrofoil board boosters cannot be handheld or bound. Therefore, users have to buy three different types of equipment, thereby causing a lot of waste.
- b. Existing non-powered hydrofoil boards (including hydrofoil boards, hydrofoil wind wing boards, hydrofoil wind surfing boards, hydrofoil paddle boards, and the like) can be propelled only by wind or manpower, which raises relatively strict requirements for physical fitness and endurance of users. In fact, it is difficult for ordinary people and beginners to master this sports skill. When the wind is too weak or it is against the wind, a non-powered hydrofoil board cannot be used normally. Only after being transferred to a windy area by manpower can the non-powered hydrofoil board be used.
- c. Existing portable underwater propellers that can be carried on airplanes can only provide an electricity output of no more than 100 WH and an endurance of usually no longer than 40 min, so that use needs cannot be satisfied. Large capacity batteries cannot be conveniently carried on airplanes, and it is inconvenient for users to carry them during long-distance travel.
To solve the above problems, it is necessary to optimize and improve structures of underwater propellers.
