Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, specifically to a commuter walking shoe sole. Background Technology
[0002] As one of the main sweat glands in the human body, the sweat glands on the soles of the feet account for more than 70% of the total sweat secretion in the feet. Therefore, the breathability of shoes is crucial. However, the breathability design of traditional footwear has significant limitations: First, existing airflow channels are mostly concentrated in the shoe opening and upper, while the sole area, which directly contacts the foot, lacks an effective breathable structure; second, sweat tends to accumulate in specific anatomical areas of the foot (such as the forefoot and arch). These structural defects lead to the following series of problems: (1) Functional defects: Sweat retention will damage the friction coefficient between the sole of the foot and the insole of the shoe, increasing the risk of slipping while walking. At the same time, the formation of liquid water film significantly reduces the heat insulation efficiency of the shoe cavity in winter (the thermal conductivity increases by about 40%). (2) Hygiene issues: The continuous damp environment keeps the relative humidity inside the shoes above 85%RH for a long time, providing ideal breeding conditions for microorganisms such as Staphylococcus epidermidis and Trichophyton rubrum, which is an important factor in the increased incidence of tinea pedis. (3) Deterioration of comfort: In summer, the temperature inside the shoe can reach 35-38℃, and the humidity index (PMV) exceeds +2.5. In winter, the damp and cold feeling will reduce the perceived temperature by 3-5℃.
[0003] Existing technologies that increase the mesh size of the shoe upper or use moisture-absorbing materials have failed to fundamentally solve the vapor pressure balance problem in the sole area.
[0004] Therefore, developing a commuter walking shoe sole based on fluid dynamics principles, with an active ventilation system to establish a continuous gas phase channel from the sole contact surface to the outside, has become a key technological breakthrough for improving the foot microenvironment. Summary of the Invention
[0005] The purpose of this invention is to provide a commuter walking shoe sole that establishes a continuous air phase channel from the sole contact surface to the outside, reducing sweat accumulation and improving comfort and health.
[0006] To solve the above technical problems, this utility model adopts the following technical solution: a commuter walking shoe sole, including a sole body, the sole body including an upper bottom layer and a lower bottom layer, the bottom of the upper bottom layer having crisscrossing flow channels, the outer contour of the flow channels forming a closed loop, the overall shape of the flow channels resembling a tortoise shell, the upper bottom layer having several vertically connected ventilation holes, the ventilation holes being connected to the flow channels, the rear side of the bottom of the several upper bottom layers having an air bladder groove, the air bladder groove being connected to the flow channels through an air intake channel, the side of the upper bottom layer having an exhaust channel, the air bladder groove being connected to the exhaust channel through a connecting channel, and the upper bottom layer having a waterproof and breathable structure covering the exhaust channel.
[0007] Using the above technical solution, when the heel lifts during walking, the elasticity of the sole structure causes the compressed air bladder groove to recover, creating a pressure difference. This draws in gas from the flow channel through the air intake channel. When the gas is expelled from the flow channel, the pressure difference draws in gas from the shoe cavity through the ventilation holes, allowing the gas inside the shoe cavity to reach the air bladder groove. Due to the shape and structure of the flow channel, the gas can flow quickly without obstruction. When the heel lands, the compressed air bladder groove compresses the gas, which is then discharged through the connecting channel to the exhaust channel and outwards. This achieves air circulation between the inside and outside of the shoe, increasing breathability, reducing sweat accumulation, and improving comfort and health. It promotes rapid sweat evaporation and optimizes the air environment inside the shoe during wear. The exhaust channel is located on the side of the upper bottom layer, increasing the air circulation area and the contact efficiency between the gas and the outside environment, facilitating rapid gas expulsion. The waterproof and breathable structure not only allows gas to escape through the exhaust channel but also blocks external moisture, preventing it from entering the shoe.
[0008] As a further optimization of this utility model, the ventilation holes include a number of first ventilation holes located on the front side of the upper bottom layer and a number of second ventilation holes located at the middle bottom of the upper bottom layer.
[0009] Using the above technical solution, the position of the first through hole corresponds to the position of the forefoot, and the position of the second air hole corresponds to the position of the arch of the foot. These are all areas of the foot that generate heat and sweat a lot. The targeted structure allows the heat from the foot to be quickly discharged through the through holes and vents, thereby reducing the accumulation of sweat.
[0010] As a further optimization of this utility model, the exhaust channel includes a strip-shaped main channel and several branch channels staggered on both sides of the main channel, and both ends of the branch channels are connected to the main channel.
[0011] By adopting the above technical solution, the main channel and the branch channel work together to form a good gas flow environment, divert the gas, increase the gas flow area, and increase the contact efficiency between the gas and the outside world, thereby facilitating the rapid discharge of gas and better expelling it from the shoe.
[0012] As a further optimization of this utility model, the waterproof and breathable structure includes an inner layer, a waterproof and breathable part, and an outer layer arranged sequentially from the inside to the outside. The inner layer and the outer layer are each provided with a number of vent holes, which are arranged one-to-one with the inner and outer layers. The waterproof and breathable part includes a first protective layer, a puncture-resistant layer, a waterproof and breathable layer, a second protective layer, and a mud-blocking mesh layer arranged sequentially from the inside to the outside.
[0013] Using the above technical solution, when gas flows from the exhaust channel to the outside, it passes through the exhaust holes of the inner layer, the waterproof and breathable part, and the exhaust holes of the outer layer in sequence. The first and second protective layers enhance the structural strength of the waterproof and breathable structure. The waterproof and breathable layer is made of waterproof and breathable membrane material, which plays the role of waterproof and breathable. The puncture-proof layer can prevent sharp objects from penetrating the waterproof and breathable structure and protect the feet. The mud-blocking mesh layer can block the mud, sand and gravel from the outside.
[0014] As a further optimization of this utility model, an insole is provided on the upper part of the sole body, and the surface of the insole is provided with anti-slip protrusions, the anti-slip protrusions including a first protrusion corresponding to the forefoot position and a second protrusion corresponding to the arch position.
[0015] Using the above technical solutions, the anti-slip protrusions can prevent the socks from slipping in the shoe cavity due to sweat. The first protrusion improves the anti-slip performance of the forefoot, and the second protrusion improves the anti-slip performance of the arch. These are all areas where the feet generate heat and sweat a lot. The targeted structure can play an anti-slip role when the feet produce sweat.
[0016] As a further optimization of this utility model, the upper surface of the upper layer is provided with crisscrossing air collection channels, and the plurality of air vents are connected to the air collection channels.
[0017] By adopting the above technical solution, the gas inside the shoe can be deposited and accumulated in the gas collection channel. When a pressure difference occurs in the vent, the gas can be quickly drawn into the gas collection channel, further improving the efficiency of gas circulation.
[0018] The beneficial effects of this utility model are as follows: it realizes air circulation between the inside and outside of the shoe, increases breathability, thereby reducing sweat accumulation, improving comfort and health, promotes rapid sweat expulsion, optimizes the air environment inside the shoe during wear, and improves the gas circulation area by setting the exhaust channel on the side of the upper bottom layer, thereby increasing the contact efficiency between the gas and the outside environment and facilitating the rapid expulsion of gas. The waterproof and breathable structure can block external moisture while expelling gas to the outside through the exhaust channel, preventing external moisture from entering the shoe.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example 1:
[0022] See appendix Figure 1-5The present embodiment of the present utility model further provides: a commuter walking shoe sole, including a sole body, the sole body including an upper bottom layer 11 and a lower bottom layer 12, the bottom of the upper bottom layer 11 is provided with a cross-shaped flow channel 3, the outer contour of the flow channel 3 can form a closed loop, the overall shape of the flow channel 3 is in the shape of a turtle shell bamboo, the upper bottom layer 11 is provided with a number of ventilation holes that run through the upper and lower parts, the ventilation holes are connected to the flow channel 3, specifically, the ventilation holes include a number of first air holes 21 provided on the front side of the upper bottom layer 11 and a number of second air holes 22 provided on the midsole of the upper bottom layer 11; The bottom rear side of several upper and lower layers 11 is provided with airbag grooves 4, which are connected to the flow channel through an air intake channel 5. The side of the upper and lower layers 11 is provided with an exhaust channel 7, which is connected to the airbag grooves 4 and the exhaust channel 7 through a connecting channel 6. Furthermore, the exhaust channel 7 includes a strip-shaped main channel 71 and several branch channels 72 that are staggered on both sides of the main channel 71. Both ends of the branch channels 72 are connected to the main channel 71. The upper layer 11 is covered with a waterproof and breathable structure 8 on the exhaust channel 7. The bottom end of the waterproof and breathable structure 8 is fixedly connected to the lower layer 12, and the surface is attached and fixed to the upper layer 11. Specifically, the waterproof and breathable structure 8 includes an inner layer 81, a waterproof and breathable part, and an outer layer 82 arranged sequentially from the inside to the outside. Both the inner layer 81 and the outer layer 82 are provided with a number of exhaust holes 83, which are arranged one-to-one with the inside and outside. The waterproof and breathable part includes a first protective layer 84, a puncture-proof layer 85, a waterproof and breathable layer 86, a second protective layer, and a mud-blocking mesh layer 88 arranged sequentially from the inside to the outside. Furthermore, the sole also includes a midsole located above the upper bottom layer 11. The midsole is made of a composite material of bamboo fiber and bio-based material, which has the properties of moisture absorption and quick drying, and antibacterial properties, increasing the antibacterial properties of the shoe and further improving breathability.
[0023] Furthermore, an insole 9 is provided on the upper part of the sole body. The surface of the insole 9 is provided with anti-slip protrusions. The anti-slip protrusions include a first protrusion 91 corresponding to the forefoot position and a second protrusion 92 corresponding to the arch position. The anti-slip protrusions can prevent the socks from slipping in the shoe cavity due to sweat. The first protrusion improves the anti-slip performance of the forefoot and the first protrusion improves the anti-slip performance of the arch. These are areas where the feet generate heat and sweat a lot. The targeted structure can play an anti-slip role when the feet produce sweat.
[0024] The principle of this embodiment is as follows: When the heel is lifted during walking, the sole structure is elastic. After the compressed air bladder groove 4 is elastically restored, a pressure difference is generated, which draws the gas in the flow channel through the air intake channel 5. When the gas in the flow channel is discharged, a pressure difference is generated, which draws the gas in the shoe cavity through the ventilation hole, so that the gas in the shoe cavity reaches the air bladder groove 4. Due to the shape and structure of the flow channel, the gas can flow quickly without being blocked. When the heel lands, the air bladder groove 4 is compressed, and the gas is discharged through the connecting channel 6 to the exhaust channel 7 and then outwards. This achieves air circulation between the inside and outside of the shoe, increases breathability, reduces sweat accumulation, and improves comfort and health. It promotes the rapid discharge of sweat and optimizes the air environment inside the shoe during wear. The exhaust channel 7 is located on the side of the upper bottom layer 11 to increase the air circulation area. The main channel 71 and the branch channel 72 work together to form a good air circulation environment, diverting the gas, increasing the air circulation area, and increasing the contact efficiency between the gas and the outside, thus facilitating the rapid discharge of gas. The waterproof and breathable structure 8 allows air to escape through the exhaust channel 7 while blocking external moisture, preventing it from entering the shoe. As air flows from the exhaust channel 7 to the outside, it passes through the exhaust holes 83 of the inner layer 81, the waterproof and breathable part, and the exhaust holes 83 of the outer layer 82. The first protective layer 84 and the second protective layer 87 enhance the structural strength of the waterproof and breathable structure 8. The waterproof and breathable layer 86 is made of waterproof and breathable membrane material, providing waterproof and breathable functions. The puncture-resistant layer 85 prevents sharp objects from penetrating the waterproof and breathable structure 8, protecting the foot. The mud-blocking mesh layer 88 blocks external mud, sand, and gravel. Example 2:
[0025] See appendix Figure 6 In this embodiment, based on the scheme of embodiment one, the upper surface of the upper bottom layer 11 is provided with crisscrossing air collection channels 31, and the outer contour of the air collection channels 31 can form a closed loop. The plurality of air vents are connected to the air collection channels.
[0026] The principle of this embodiment is that the gas inside the shoe can be deposited and accumulated in the gas collection channel 31. When a pressure difference occurs in the vent, the gas can be quickly drawn into the gas collection channel 31, further improving the efficiency of gas circulation.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
