Problems solved by technology

[0003] For swimming enthusiasts, swimming and playing in the water is a kind of exercise and a very interesting thing. It is a favorite sport for most people, but it consumes a lot of energy. For most people, their physical strength cannot keep up. , there is a danger of drowning if you stay in the water for a long time

[0004] However, swimming requires a certain skill, which is not something that ordinary people can do. Those who can't have to use other tools to do it.

Now generally all rely on life-saving tools, using life-saving tools is not only difficult to learn to swim, but also can not feel the real fun of swimming

At the same time, for people who can swim, in order to increase their swimming speed, they generally use auxiliary tools such as flippers or electric propellers, but the use of flippers cannot improve the faster speed, and the cost of electric propellers is too expensive, not for ordinary swimmers. can bear

[0005] At the same time, another disadvantage of electric propulsion is that it uses battery power supply for power supply, and the battery has potential safety hazards in the water. In addition, due to the limitation of battery technology, the working time of this type of propeller is relatively short, and the market product logo can last up to 50 years. minutes, but after a period of use, the actual use is mostly 20 to 30 minutes, and the same price is thousands or thousands of yuan
