[0002] In modern society, people pay more and more attention to health, and vital capacity, as an important indicator of human respiratory system function, has also received more attention. Vital capacity training devices have emerged as the times require, and their emergence has many background factors. With the change of lifestyle, sedentary and lack of exercise have become the norm, which leads to the gradual decline of the cardiopulmonary function of many people. In some specific professions, such as singers, athletes, wind instrument players, etc., good vital capacity is the key to excellent performance. In addition, environmental pollution, bad breathing habits, etc. also have a certain impact on people's respiratory system. In order to meet the needs of people to improve vital capacity, scientific researchers have developed various vital capacity training devices through continuous exploration and innovation. These devices aim to help users effectively exercise respiratory muscles and enhance the expansion and contraction of the lungs through scientific methods and designs, thereby improving vital capacity. Early vital capacity training devices were relatively simple and had relatively single functions.
