Description

Technical Field

[0001] This utility model relates to the field of shoe soles, and in particular to a shock-absorbing and odor-eliminating shoe sole. Background Technology

[0002] In the field of footwear technology, the performance of the sole is crucial to the wearing experience and product lifespan. Traditional soles, limited by materials, have low rebound rates and rapid cushioning degradation, making it difficult to maintain good wearing comfort over a long period and failing to meet consumers' demand for stable cushioning over extended periods.

[0003] To improve cushioning and other performance characteristics, existing technologies attempt to add air cushions to the soles of shoes. However, if the air chambers of the air cushions are too small, the shock absorption effect is poor. If the air chambers of the air cushions are too large, but the air cushions lack a gas cushioning structure, they are prone to edge breakage or cracking and air leakage during use, leading to failure of the sole's shock absorption, short service life, increased consumer usage costs and replacement frequency, and also hindering the market promotion of footwear products. Utility Model Content

[0004] This invention provides a shock-absorbing and odor-eliminating shoe sole to solve the problem that existing shoe soles lack a gas cushioning structure and are prone to chipping and cracking.

[0005] The present invention adopts the following technical solution: A shock-absorbing and odor-eliminating shoe sole includes a midsole with an insole stacked on top. An air cushion is provided inside the insole. The forefoot and heel portions of the air cushion are respectively provided with a first air chamber and a third air chamber. The arch portion of the air cushion is provided with a second air chamber. An air supply channel is provided between the second air chamber and the first and third air chambers. The air supply channel contains a Tesla valve structure, and the direction away from the second air chamber along the air supply channel is the low-resistance direction of the Tesla valve structure.

[0006] Furthermore, the air cushion is provided with an air inlet channel in the middle that connects to the second air chamber.

[0007] Furthermore, the surface of the insole is covered with a mesh layer made of cross-woven bamboo charcoal fibers.

[0008] Furthermore, the aforementioned insole is bonded and laminated onto the midsole.

[0009] Furthermore, the aforementioned midsole is made of EVA material.

[0010] Furthermore, the bottom surface of the aforementioned midsole is bonded with an outsole, which has an anti-slip pattern.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. The midsole of this utility model is provided with three air chambers, and an air supply channel with a Tesla valve structure is provided between the three air chambers. The Tesla valve structure works in conjunction with the second air chamber to optimize the gas cushioning structure, which not only solves the problem of poor shock absorption due to small air chambers, but also avoids edge chipping, cracking and air leakage when the air chambers are large, thus ensuring the effectiveness of shock absorption of the sole.

[0012] 2. The sole of this utility model effectively breaks through the limitations of traditional sole materials, greatly improves the rebound rate, slows down the decay rate of shock absorption performance, and maintains good wearing comfort in a long-term stable manner, meeting consumers' long-term stable shock absorption needs; it reduces the risk of shortened lifespan due to shock absorption failure of the sole, reduces consumer usage costs and replacement frequency, and is conducive to the market promotion of footwear products.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] Reference Figures 1-4A shock-absorbing and odor-eliminating shoe sole includes a midsole 2, on which an insole 1 is stacked. An air cushion 10 is provided inside the insole 1. The insole 10 has a first air chamber 101 and a third air chamber 103 respectively on the forefoot and heel parts. The first air chamber 101 is located at the position supporting the forefoot, and the third air chamber 103 is located at the position supporting the heel. The air cushion has a second air chamber 102 in the arch area. The second air chamber 102 is connected to the first air chamber 101 and the third air chamber 103 by an air supply channel 12. The air supply channel 12 is a Tesla valve structure. The direction away from the second air chamber 102 along the air supply channel 12 is the low resistance direction of the Tesla valve structure. The direction from the first air chamber 101 to the second air chamber 102 along the air supply channel 12 is the high resistance direction of the Tesla valve structure. The direction from the third air chamber 103 to the second air chamber 102 along the air supply channel 12 is the high resistance direction of the Tesla valve structure. The second air chamber 102 is used to buffer the gas in the first air chamber 101 and the third air chamber 103.

[0020] Reference Figure 1 The air cushion 10 is provided with an air inlet channel 11 in the middle, which connects to the second air chamber 102. The air inlet channel 11 is used to fill gas into all the air chambers. After filling with gas, the air inlet channel 11 is thermally sealed.

[0021] Reference Figure 4 The surface of the insole 1 is covered with a mesh layer 13, which is made of bamboo charcoal fiber cross-woven. The mesh layer 13 has good breathability, reduces the production of sweat on the soles of the feet, and the bamboo charcoal fiber mesh layer 13 has antibacterial and deodorizing functions.

[0022] The insole 1 is bonded to the midsole 2. The insole 1 is not easy to shift on the midsole 2, ensuring that the air chamber is aligned with the foot and heel for support.

[0023] The aforementioned midsole 2 is made of EVA material, and the midsole 2 itself has elastic shock absorption function, making it more comfortable to wear.

[0024] Reference Figure 3 , Figure 5 The bottom surface of the midsole 2 is bonded with the outsole 21, which has anti-slip patterns. The upper 3 is sewn onto the upper edge of the midsole 2.

[0025] Reference Figures 1-5When a user walks wearing shoes with the soles of this invention, the ball of the foot and the heel repeatedly and alternately press down on the sole. When the ball of the foot touches the ground, the gas in the first air chamber 101 flows along the gas delivery channel 12 to the second air chamber 102. The Tesla valve structure of the gas delivery channel 12 obstructs the gas coming from the first air chamber 101. Because the gas delivery channel 12 is short and the friction between the gas and the inner wall of the gas delivery channel 12 is small, the gas in the first air chamber 101 can reach the second air chamber 102. When the foot is lifted off the ground, the ball of the foot no longer presses down on the first air chamber 101, releasing the pressure. At this time, the air pressure in the first air chamber 101 is at its minimum, and the gas in the second air chamber 102 can enter the first air chamber 101 along the gas delivery channel 12. Similarly, when the heel touches the ground, the gas in the third air chamber 103 flows along the gas delivery channel 12 towards the second air chamber 102. The Tesla valve structure of the gas delivery channel 12 obstructs the gas coming from the third air chamber 103. Due to the short length of the gas delivery channel 12 and the low friction between the gas and the inner wall of the gas delivery channel 12, the gas in the third air chamber 103 can reach the second air chamber 102. When the foot is lifted off the ground, the heel does not press on the third air chamber 103. At this time, the air pressure in the third air chamber 103 is at its minimum, and the gas in the second air chamber 102 can enter the third air chamber 103 along the gas delivery channel 12. This process is repeated alternately. The Tesla valve structure and the second air chamber 102 work together to buffer the gas in the first air chamber 101, resulting in good shock absorption.

[0026] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
