Problems solved by technology

However, no matter which inflatable you use, it will be weird and inconvenient to swim in
Therefore, in fact, almost no one in the swimming pool will wear such a life-saving device to swim

Embodiment 1

[0033] The inventor of the present application discovered an important common phenomenon when practicing swimming in a swimming pool. When the human body is full of air in the lungs and the entire body including the head enters the water, the overall density of the human body is less than the water density (at this time) The human body will float on the water surface, and part of the human body structure, such as the head, will be exposed to the surface of the water; however, the overall density of the human body will be slightly greater than the density of the water when the human body exhales until the lungs are exhausted. sink). Therefore, to prevent adult drowning, you need to ensure that you keep your head above the water and breathe normally when the body is completely empty of lung gas. Therefore, the buoyancy provided by the low-density layer of the present invention is primarily designed as the product of the sum of human vital capacity (V1) and head volume (V2), the m...

Embodiment 2

[0050] figure 1 with figure 2 A swimming life jacket in the present invention is shown in the present invention. It includes a low-density layer 1 of soft foam plastic and a high-density layer 2 of steel material combined with a mesh block. The low-density layer and the high-density layer can be arranged separately, The density of the density layer is about 0.2g / cm 3 , The density of the high-density layer is about 7.9g / cm 3 ; And the overall density of the swimming lifejacket including the low-density layer and the high-density layer is about 1g / cm 3 After the swimming life jacket is worn, the low-density layer is fixed on the upper body of the human body through the zipper, or the low-density layer is set in one piece and the head and arms of the human body are extended to wear the low-density layer, and the high-density layer is through the zipper It is fastened directly or indirectly to the upper body of the human body; when the wearer puts on the swimming lifejacket, the ov...

Abstract

The invention provides a life jacket for swimming, comprising a low-density layer and a high-density layer which can be arranged separately, the density of the low-density layer is less than 1g / cm3, and the density of the high-density layer is greater than 1g / cm3; and the low-density layer and the high-density layer are included The swimming life jacket has an overall density of 0.2 to 3 g / cm3; the low-density layer is fixed at least on the upper body of the human body after wearing the swimming life jacket, and the high-density layer is directly or indirectly fixed on the low-density layer and / or on the On the human body; when the wearer puts on the swimming life jacket, the difference between the overall density of the swimming life jacket and the density of water affects the wearer's swimming difficulty in the water; when the wearer or bystanders feel that the wearer is in danger of drowning When the wearer wears it, the high-density layer can be released immediately, and the low-density layer fixed on the human body can save the life of the wearer. When wearing the swimming life jacket of the present invention to swim, there is no need to worry about drowning caused by accidents such as cramping, slipping and bumping.

Description

Technical field [0001] The invention belongs to the field of life-saving devices or swimming devices, and specifically relates to a swimming life jacket. Background technique [0002] Swimming is a skill in which a person floats upwards under the buoyancy of water, and uses buoyancy to make regular movements of the body in the water. Swimming has the effects of improving the cardiovascular system, increasing vital capacity, improving the function of the respiratory system, improving the ability of the muscular system, improving the mechanism of body temperature regulation, strengthening skin blood circulation, enhancing resistance, weight loss, and bodybuilding. Many people love. [0003] But even for people who can swim, whether they are swimming wild in rivers, lakes, or swimming pools, there is a certain probability of drowning. For example, sudden cramps in the hands and feet after the human body is in the water can cause a person who can swim to drown in deep water. However...
