Description

Technical Field

[0001] The utility model relates to the technical field of shoes, and more specifically to a breathing insole. Background Art

[0002] Shoes are worn on the feet to protect the feet and facilitate walking. They are generally made of leather, cloth, rubber and other materials. With the development of society, shoes of various styles and functions can be seen everywhere.

[0003] When the shoes are used, the shoe body wraps the entire foot. When the amount of exercise is large or walking for a long time, the air in the shoe cannot be exchanged with the outside air in time, a relatively dense environment is formed in the shoe, and heat cannot be dissipated. The feet are prone to sweating and breeding bacteria, which leads to the problem of foot odor and shoe odor. Although there are sports shoes on the market with porous mesh uppers to increase the exhaust of the feet, the space between the bottom of the sole and the insole still forms a relatively independent and closed space, the air circulation is not smooth, and the problem of foot odor and shoe odor cannot be effectively solved. The utility model proposes a new solution to the above problems. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a breathing insole to solve the technical problems mentioned in the background technology.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A breathing insole comprises an insole shell, wherein the upper end surface of the insole shell is provided with an installation cavity, the upper end surface of the installation cavity is provided with a placement opening, a filling layer made of elastic material is embedded in the installation cavity, a plurality of elastic air cavities interconnected are formed in the filling layer, the upper end surface of the filling layer is provided with air holes, the air holes are connected with some of the elastic air cavities therein, an elastic pressing edge is fixed on the inner side of the placement opening, and the outer edge of the upper end surface of the filling layer is in contact with the elastic pressing edge.

[0007] Preferably, a support layer is provided in the installation cavity, the bottom of the support layer is fixedly connected to the installation cavity, and the lower end surface of the filling layer is in contact with the end surface of the support layer.

[0008] In any of the above solutions, preferably, a plurality of friction protrusions are provided on the upper end surface of the support layer.

[0009] In any of the above schemes, it is preferred that a well-shaped partition is provided in the support layer, and the well-shaped partition divides the support layer into a plurality of cavities.

[0010] In any of the above schemes, preferably, a wear-resistant layer is bonded to the lower end surface of the insole shell, and a plurality of groups of friction stripes are arranged on the wear-resistant layer.

[0011] In any of the above solutions, preferably, a dustproof net is provided on the air hole.

[0012] Preferably, in any of the above schemes, a bottom hole is opened at a position of the insole shell corresponding to the air hole, the bottom hole is connected to the air hole, and the bottom hole extends to the lower end surface of the insole shell.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] In the design of the filling layer of the utility model, the outer shell of the insole is made of airtight material, the filling layer is made of low-density elastic material, the elastic air cavity in the filling layer is filled with air, and the air holes are connected with the shoe cavity. When the user puts the insole into the shoe and walks, when the foot lands, the sole of the foot presses the filling layer, the elastic air cavity is compressed, the air in the elastic air cavity is squeezed out, and discharged into the shoe cavity through the air holes. Because the space of the shoe cavity is limited, the air discharged from the elastic air cavity will blow the air in the shoe cavity outward into the external environment. When the foot is lifted, the filling layer is compressed. When the filling layer loses external pressure, under the action of its own elasticity, the elastic air cavity returns to its original state, and the air in the shoe cavity is sucked into the elastic air cavity through the air holes, and the air outside the shoe is replenished into the shoe cavity. This process is repeated, and the air in the shoe cavity is continuously replaced during walking or running and jumping. During the replacement process, part of the sweat and odor generated by exercise is taken away, keeping the air in the shoe cavity smooth, thereby achieving free breathing of the insole, improving the comfort of the foot and reducing bacterial growth. In addition, the filling layer has a certain cushioning effect on the sole of the foot, which can further improve the comfort of the foot. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The insole shell 1 is made of airtight material, and the filling layer 4 is made of low-density elastic material. The elastic air cavity 5 in the filling layer 4 is filled with air, and the air hole 6 is connected with the shoe cavity. When the user puts the insole into the shoe and walks, when the foot lands, the sole presses the filling layer 4, the elastic air cavity 5 is compressed, and the air in the elastic air cavity 5 is squeezed out and discharged into the shoe cavity through the air hole 6. Due to the limited space in the shoe cavity, the air discharged from the elastic air cavity 5 will blow the air in the shoe cavity outward into the external environment. When the foot is lifted, the filling layer 4 loses its elasticity. After the external pressure is removed, the elastic air cavity 5 returns to its original state under the action of its own elasticity, and the air in the shoe cavity is sucked into the elastic air cavity 5 through the air hole 6, and the air outside the shoe is replenished into the shoe cavity. This process is repeated, and the air in the shoe cavity is continuously replaced during walking or running and jumping. During the replacement process, part of the sweat and odor generated by exercise are taken away, and the air in the shoe cavity is kept smooth, thereby achieving free breathing of the insole, improving the comfort of the foot and reducing bacterial growth. In addition, the filling layer 4 has a certain cushioning effect on the sole of the foot, which can further improve the comfort of the foot.

[0030] The working process of the utility model is as follows:

[0031] The insole shell 1 is made of airtight material, and the filling layer 4 is made of low-density elastic material. The elastic air cavity 5 in the filling layer 4 is filled with air, and the air hole 6 is connected with the shoe cavity. When the user puts the insole into the shoe and walks, when the foot lands, the sole presses the filling layer 4, the elastic air cavity 5 is compressed, and the air in the elastic air cavity 5 is squeezed out and discharged into the shoe cavity through the air hole 6. Due to the limited space in the shoe cavity, the air discharged from the elastic air cavity 5 will blow the air in the shoe cavity outward into the external environment. When the foot is lifted, the filling layer 4 loses its elasticity. After the external pressure is removed, the elastic air cavity 5 returns to its original state under the action of its own elasticity, and the air in the shoe cavity is sucked into the elastic air cavity 5 through the air hole 6, and the air outside the shoe is replenished into the shoe cavity. This process is repeated, and the air in the shoe cavity is continuously replaced during walking or running and jumping. During the replacement process, part of the sweat and odor generated by exercise are taken away, and the air in the shoe cavity is kept smooth, thereby achieving free breathing of the insole, improving the comfort of the foot and reducing bacterial growth. In addition, the filling layer 4 has a certain cushioning effect on the sole of the foot, which can further improve the comfort of the foot.
