Swimming can be carried out in a swimming pool or outdoors. Swimming enthusiasts are often troubled by problems such as swimming safety, fun, and poor adjustment of exercise intensity during swimming training. People hope that there is a swimming auxiliary equipment that can enhance swimming. The safety of sports is interesting at the same time, and it is also convenient to adjust the exercise intensity, which can be used as an effective auxiliary equipment to enhance swimming physical training

[0003] At present, there are many types of life-saving equipment and learning equipment for swimming, such as "followers", "Yonglebao", "life buoy" and "life jacket", etc., but the functions of these swimming equipment are often relatively single, and there are one or another Defects, such as "life buoy" and "life jacket" are mainly used to enhance the safety of swimming, it is not easy to learn to use, let alone adjust the training intensity of swimming; "Yonglebao" is mainly used for beginners; "follower" can be used as an adult A kind of swimming safety equipment, but can not adjust the intensity of swimming training, so the existing technology can not meet people's requirements
