Description

Technical Field

[0001] This utility model relates to the field of insole technology, specifically to an inflatable insole. Background Technology

[0002] Chinese Utility Model Patent Application No. CN202121180574.3 discloses an inflatable insole with a structure including an insole body. The insole body is formed into a first cavity and a second cavity by hot pressing. The first cavity is located at the forefoot position of the insole body, and the second cavity is located at the heel position. The first cavity contains a plurality of first air bladders. This inflatable insole reduces cushioning through the air bladders and cavities, and dissipates heat from the soles of the feet through the first and second ventilation holes. However, when people walk, the movement intensity of the soles of the feet is relatively high, and there are many sweat glands on the soles of the feet. Moreover, the soles of the feet are far from the shoe opening, resulting in relatively hot and humid conditions. When in use, this insole can only blow air towards the soles of the feet, thus failing to effectively dissipate heat. In addition, the air bladders in this insole only rebound through their own elasticity. After prolonged use, the elasticity of the air bladders will decrease significantly, causing the air bladders to fail to rebound to their original state, thereby affecting the air circulation effect.

[0003] Therefore, it is necessary to propose an inflatable insole to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide an inflatable insole to solve the problem mentioned in the background art that the existing inflatable insole can only blow air from the sole of the foot to the sole, thus failing to effectively dissipate heat from the sole. In addition, the air bladder in the insole only rebounds by its own elasticity. When the insole is used for a long time, the elasticity of the air bladder will decrease significantly, thus causing the air bladder to fail to rebound to its original state, thereby affecting the air circulation effect.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: An inflatable insole includes an insole and a ventilation component disposed within the insole. The insole has cavities at both the sole and heel. The ventilation component includes annular airbags I and II, respectively disposed within the two cavities, and a balloon disposed in the middle of annular airbags I and II. Annular airbags I, II, and the balloon are all fixedly connected to the inner walls of adjacent cavities. Annular airbag I is located at the heel, and annular airbag II is located at the sole. Annular airbags I and II are connected, as are the two balloons. The input end of annular airbag I and the output end of annular airbag II are both connected to the external environment, and a one-way valve is provided at both the input and output ends of annular airbag I.

[0006] Preferably, the insole includes an elastic layer and a wear-resistant layer adhered to the upper and lower parts of the elastic layer. The cavity is formed on the elastic layer, and the elastic layer also has a connecting groove connecting the two cavities.

[0007] Preferably, both the annular airbag I and the annular airbag II are C-shaped, and the openings of the annular airbag I and the annular airbag II are arranged opposite to each other. A connecting tube I is fixedly installed at the output end of the annular airbag I, and the other end of the connecting tube I is connected to the annular airbag II. A connecting tube II is provided between the two airbags to connect the two.

[0008] Preferably, multiple air inlet pipes communicating with the interior are evenly fixedly installed on the periphery of the annular airbag I, and multiple exhaust pipes communicating with the interior are evenly fixedly installed on the periphery of the annular airbag II. The other ends of the air inlet pipes and exhaust pipes pass through the insole, and one-way valves are provided in the connecting pipe I and the multiple air inlet pipes.

[0009] Beneficial Effects: Compared with the prior art, this utility model provides an inflatable insole with a unique structure and convenient use. When the user walks, the heel first compresses the annular airbag I and the ball bladder located at the heel. At this time, the air in the annular airbag I is compressed and enters the annular airbag II located at the ball of the foot through the connecting tube I. At the same time, the air in the ball bladder at the heel flows into the ball bladder at the ball of the foot through the connecting tube II. When the ball of the foot lands, the ball of the foot compresses the annular airbag II and the ball bladder at the ball of the foot. The air in the annular airbag II is discharged through the exhaust pipe, and the air in the ball bladder at the ball of the foot flows back to the ball bladder at the heel, causing the ball bladder at the heel to inflate. This pushes the annular airbag I to rebound quickly under the action of the elastic layer and its own elasticity. At the same time, external air is drawn in through the air inlet pipe. When the heel lands again, the air in the annular airbag I is discharged from the ball of the foot. This cycle is repeated to achieve efficient air flow inside the shoe.

[0010] By combining the dual-ring airbags and the ball-shaped airbag, not only can air be continuously delivered from the shoe opening to the foot, accelerating air circulation inside the shoe, improving heat dissipation, keeping the feet dry and comfortable, and effectively relieving stuffiness, but it can also prevent the insole from being completely compressed at the heel and foot. While improving the shock absorption effect, it also significantly accelerates the rebound effect of ring airbag I and ring airbag II and the duration of the rebound ability.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This Example 1 provides an inflatable insole, which is a direct improvement on existing inflatable insoles. It has a unique structure. Please refer to [link / reference]. Figure 1-3 As shown, the shoe includes an insole and a ventilation component 2 disposed within the insole. The insole has cavities at the sole and heel. The ventilation component 2 includes annular airbags I 21 and II 22 disposed within the two cavities, and a balloon 23 disposed in the middle of the annular airbags I 21 and II 22. The annular airbags I 21, II 22, and 23 are all fixedly connected to the inner walls of adjacent cavities. The annular airbag I 21 is located at the heel, and the annular airbag II 22 is located at the sole. The annular airbags I 21 and II 22 are connected, and the two balloons 23 are connected. The input end of the annular airbag I 21 and the output end of the annular airbag II 22 are both connected to the external environment, and a one-way valve 25 is provided in both the input and output ends of the annular airbag I 21.

[0017] The insole includes an elastic layer 11 and a wear-resistant layer 12 adhered to the upper and lower parts of the elastic layer 11. A cavity is formed in the elastic layer 11, and a connecting groove 13 connecting the two cavities is also formed in the elastic layer 11. The elastic layer 11 can be selected from various types, such as polyurethane foam. Both annular airbags I 21 and II 22 are C-shaped, and the openings of annular airbags I 21 and II 22 are arranged opposite to each other. A connecting pipe I 24 is fixedly installed at the output end of annular airbag I 21, and the other end of the connecting pipe I 24 is connected to annular airbag II 22. A connecting pipe II 26 connecting the two airbags 23 is provided between them. Multiple air inlet pipes 27 connected to the interior of annular airbag I 21 are evenly fixedly installed on the periphery of annular airbag I 21, and multiple exhaust pipes 28 connected to the interior of annular airbag II 22 are evenly fixedly installed on the periphery of annular airbag II 22. The other ends of the air inlet pipes 27 and exhaust pipes 28 penetrate the insole, and a one-way valve 25 is provided in the connecting pipe I 24 and the multiple air inlet pipes 27.

[0018] Working principle: When the user walks, the heel first compresses the annular airbag I 21 and the heel-mounted balloon 23. At this time, the air in the annular airbag I 21 enters the annular airbag II 22, and the air in the heel-mounted balloon 23 enters the ball-of-the-foot balloon 23. When the ball of the foot lands, the ball of the foot simultaneously compresses the annular airbag II 22 and the ball-of-the-foot balloon 23. At this time, the air in the annular airbag II 22 is discharged through the exhaust pipe 28, and the air in the ball-of-the-foot balloon 23 flows back to the heel-mounted balloon 23, causing the heel-mounted balloon 23 to inflate. This causes the annular airbag I 21 to expand within the elastic layer 11 and the ball-of-the-foot balloon. The insole 23, along with its own elasticity, rebounds rapidly and draws in external air through the air intake tube 27. When the heel strikes the ground again, the air inside the annular airbag I 21 is expelled from the foot. This method not only continuously delivers air from the shoe opening to the foot for heat dissipation, but also, through the design of the two airbags 23, improves the shock absorption effect of the insole, prevents the heel and foot from being completely compressed, and significantly accelerates the rebound effect of the annular airbag I 21 and the annular airbag II 22, as well as the duration of the rebound.

[0019] Example 2: The difference between Example 2 and Example 1 is that the bottom of the insole is provided with an anti-slip pad to prevent the insole from sliding inside the shoe.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
