Description

Technical Field

[0001] This utility model relates to the field of insole technology, and in particular to a shock-absorbing, antibacterial and deodorizing insole suitable for sports shoes. Background Technology

[0002] Insoles are functional pads that fit inside athletic shoes and come into direct contact with the feet. The purpose of insoles is to improve comfort, support, shock absorption, and breathability during exercise, while also helping to correct gait and reduce foot fatigue and the risk of sports injuries.

[0003] Traditional insoles often use uniform foaming or flat structure. During exercise, a lot of sweat accumulates in the insoles of sports shoes. The accumulation of sweat leads to the growth of bacteria and the production of a musty smell inside the shoe. Traditional insoles are also prone to slipping during exercise, and once they slip, they are very uncomfortable to step on. Summary of the Invention

[0004] This invention provides a shock-absorbing, antibacterial, and deodorizing insole suitable for sports shoes. The middle shock-absorbing layer is compressed and absorbs shock simultaneously, while the middle H-shaped through holes are compressed at the same time. The compression of the middle H-shaped through holes pushes the internal gas to flow quickly through the ventilation holes of the upper antibacterial fabric layer, accelerating the surrounding air flow, accelerating the evaporation of foot sweat, improving breathability and moisture wicking performance, reducing the damp environment for bacterial growth from the source, and reducing the stuffy smell after exercise. The lower padding layer is attached to the insole of the sports shoe through the lower fleece layer to increase friction and ensure the stability of the insole position during strenuous exercise.

[0005] This invention provides a shock-absorbing, antibacterial, and deodorizing insole suitable for athletic shoes, specifically comprising: a middle shock-absorbing layer, an upper antibacterial fabric layer, and a lower insole layer. The upper antibacterial fabric layer is bonded and fixed to the top of the middle shock-absorbing layer, and the lower insole layer is bonded and fixed to the bottom of the middle shock-absorbing layer. The middle shock-absorbing layer has H-shaped through holes arranged in an array. The middle shock-absorbing layer is made of low-density foamed EVA material with a density of 0.15–0.25 g / cm³. 3 Resilience ≥ 60%.

[0006] Furthermore, the H-shaped through hole is an H-shaped structure in which two vertical through holes are connected in the middle. The H-shaped through hole runs through the top and bottom of the middle shock-absorbing pad. The compression of the H-shaped through hole generates a "pumping effect", which promotes the rapid flow of internal gas.

[0007] Furthermore, the H-shaped through holes at the front of the middle shock-absorbing pad are arranged in a rectangular array to adapt to the structure of a rectangular foot, and the H-shaped through holes at the rear of the middle shock-absorbing pad are arranged in a ring array to adapt to the structure of a round heel. The through holes account for 30% to 40% of the total structure, and the impact absorption rate is ≥50%.

[0008] Furthermore, the upper antibacterial fabric layer is provided with ventilation holes in an array, and is made of a blend of bamboo fiber and artemisia fiber with a blending ratio of 7:3. It contains antibacterial components and has a bamboo quinone content of ≥0.05%.

[0009] Furthermore, the ventilation holes and the H-shaped through holes are aligned and connected. The ventilation holes at the front of the upper antibacterial fabric layer are arranged in a rectangular array, and the ventilation holes at the rear of the upper antibacterial fabric layer are arranged in a ring array. The compression of the H-shaped through holes generates a "pumping effect". The compression of the H-shaped through holes pushes the internal gas to flow rapidly through the ventilation holes of the upper antibacterial fabric layer, accelerates the flow of surrounding air, accelerates the evaporation of sweat from the feet, and improves breathability and moisture wicking performance.

[0010] Furthermore, a lower pile layer is provided at the bottom of the lower padding layer. Both the lower padding layer and the lower pile layer are made of materials such as bamboo fiber, mugwort fiber, mint fiber, and polyimide. The antibacterial components contained in these materials can inhibit bacterial growth. The lower padding layer and the lower pile layer are made of fiber weaving. The antibacterial properties are enhanced by the volatile oil components in the fibers, and the pile structure is used to adsorb odor molecules, with an ammonia adsorption rate of ≥70%.

[0011] Furthermore, the lower fleece layer protrudes from the bottom outer side of the lower padding layer. The fleece layer has a fleece length of 2-3mm. The lower fleece layer contacts the insole of the sports shoe to achieve anti-slip and ensure the stability of the insole during vigorous exercise. The lower fleece layer faces upward and contacts the foot. The fleece structure forms an air insulation layer to improve the heat retention performance of the foot and the shoe.

[0012] This invention provides a shock-absorbing, antibacterial, and deodorizing insole suitable for sports shoes, which has the following beneficial effects:

[0013] While the middle shock-absorbing pad is compressed and absorbs shock, the middle H-shaped through holes are compressed simultaneously. The compression of the middle H-shaped through holes pushes the internal gas to flow quickly through the ventilation holes of the upper antibacterial fabric layer, accelerating the surrounding air flow, accelerating the evaporation of sweat from the feet, improving breathability and moisture wicking performance, reducing the damp environment for bacterial growth from the source, and reducing stuffiness and odor after exercise.

[0014] The lower padding layer increases friction by adhering to the inner sole of the athletic shoe through the lower fleece layer, reducing insole movement and ensuring insole stability during vigorous exercise. In winter, the lower fleece layer faces upward and contacts the foot, with the fleece structure forming an air insulation layer to improve the warmth of the foot and shoe, achieving a scenario adaptation of "sports shock absorption - daily warmth" and expanding the product's application range.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a shock-absorbing, antibacterial, and deodorizing insole suitable for sports shoes, comprising: a middle shock-absorbing layer 1, an upper antibacterial fabric layer 2, and a lower insole 3. The middle shock-absorbing layer 1 has H-shaped through holes 101 arranged in an array. The middle shock-absorbing layer 1 is made of low-density foamed EVA material with a density of 0.15-0.25 g / cm³. 3With a resilience of ≥60%, the low-density foamed EVA material middle shock-absorbing pad 1 undergoes controllable deformation under foot pressure. Graded shock absorption is achieved through the "contraction-rebound" of the H-shaped through-holes 101. The H-shaped through-holes 101 are H-shaped structures with two vertical through-holes connected in the middle. The H-shaped through-holes 101 extend vertically through the top and bottom of the middle shock-absorbing pad 1. Compression of the H-shaped through-holes 101 generates a "pumping effect," propelling the internal gas to flow rapidly. The H-shaped through-holes 101 at the front of the middle shock-absorbing pad 1 are arranged in a rectangular array to accommodate the rectangular foot structure, while those at the rear are arranged in a ring array to accommodate the round heel structure. The through-hole ratio is 30%–40%, and the impact absorption rate is ≥50%. An upper antibacterial fabric layer 2 is bonded and fixed to the top of the middle shock-absorbing pad 1. The upper antibacterial fabric layer 2 is connected through an array... The design includes ventilation holes 201 and is made of a blended fabric of bamboo fiber and artemisia fiber combined with polyimide material. It contains antibacterial components, with a bamboo quinone content ≥0.05%. The polyimide fiber felt is endowed with antibacterial properties through in-situ growth of silver nanoparticles. This composite material can effectively inhibit the spread of bacteria and viruses at room temperature. The silver nanoparticles achieve sterilization by destroying the microbial cell structure, and its antibacterial effect is long-lasting. The bottom of the middle shock-absorbing pad 1 is bonded and fixed with a lower pad 3. The bottom of the lower pad 3 is provided with a lower pile layer 301. Both the lower pad 3 and the lower pile layer 301 are made of materials such as bamboo fiber, artemisia fiber, mint fiber, and polyimide. The antibacterial components contained in these materials can inhibit bacterial growth. The lower pad 3 and the lower pile layer 301 are made of fiber weaving. The volatile oil components in the fibers enhance the antibacterial properties, achieving long-lasting antibacterial effect. The pile structure is used to adsorb odor molecules, with an ammonia adsorption rate ≥70%.

[0031] In this embodiment, the ventilation holes 201 and the middle H-shaped through holes 101 are aligned and connected. The ventilation holes 201 at the front of the upper antibacterial fabric layer 2 are arranged in a rectangular array, and the ventilation holes 201 at the rear of the upper antibacterial fabric layer 2 are arranged in a ring array. The compression of the middle H-shaped through holes 101 generates a "pumping effect". The compression of the middle H-shaped through holes 101 pushes the internal gas to flow rapidly through the ventilation holes 201 of the upper antibacterial fabric layer 2, which accelerates the flow of surrounding air, accelerates the evaporation of sweat from the feet, improves breathability and moisture wicking performance, and reduces the stuffiness and odor after exercise.

[0032] In this embodiment, the lower fleece layer 301 protrudes from the bottom outer side of the lower padding layer 3. The fleece length of the lower fleece layer 301 is 2-3 mm. The lower fleece layer 301 contacts the insole of the sports shoe to achieve anti-slip and ensure the stability of the insole position during vigorous exercise. The lower fleece layer 301 faces upward and contacts the foot. The fleece structure forms an air insulation layer to improve the heat preservation performance of the foot and shoe, achieving scenario adaptation of "sports shock absorption - daily warmth".

[0033] In this second embodiment, based on the first embodiment, the H-shaped through hole 101 can be an L-shaped channel structure. The top of the H-shaped through hole 101 in the L-shaped channel structure is connected to the outer side of the top of the middle shock-absorbing pad 1, which reduces the manufacturing difficulty of the H-shaped through hole 101 and reduces the production cost.

[0034] The working principle of this embodiment: The insole is placed inside the sports shoe. The lower pad layer 3 is attached to the insole of the sports shoe through the lower fleece layer 301 to increase friction and reduce the movement of the insole. This ensures that the insole is stable during strenuous exercise. When subjected to foot pressure, the low-density foamed EVA material middle shock-absorbing pad layer 1 undergoes controllable deformation. Through the "contraction-rebound" of the middle H-shaped through hole 101, graded shock absorption is achieved. While the middle shock-absorbing pad layer 1 is compressed for shock absorption, the middle H-shaped through hole 101 is simultaneously compressed and generates a "pumping effect". The compression of the middle H-shaped through hole 101 pushes the internal gas to flow quickly through the ventilation holes 201 of the upper antibacterial fabric layer 2, accelerating the flow of surrounding air, accelerating the evaporation of foot sweat, improving breathability and moisture wicking performance, and keeping the surface humidity of the insole below 60%. This reduces the damp environment for bacterial growth from the source and reduces the stuffiness and odor after exercise.

[0035] The bamboo fiber-artemisia fiber blend material-polyimide material of the upper antibacterial fabric layer 2 has an antibacterial rate of over 90% and 85% against Staphylococcus aureus and Escherichia coli, respectively. The polyimide fiber is endowed with antibacterial properties through in-situ growth of silver nanoparticles. This composite material can effectively inhibit the spread of bacteria and viruses at room temperature. The silver nanoparticles achieve sterilization by destroying the microbial cell structure, and its antibacterial effect is long-lasting. Moreover, the antibacterial components achieve long-lasting antibacterial effect through slow release (half-life ≥ 3 months), avoiding the risk of skin irritation from chemical antibacterial agents. The airflow circulation formed by the H-shaped through holes 101 and the ventilation holes 201 can promptly expel odor molecules (such as ammonia and volatile fatty acids) produced by foot metabolism. Combined with the adsorption characteristics of the mint fiber in the lower padding layer 3 (ammonia adsorption rate ≥ 70%), the odor level of the insole (according to GB / T35611 standard) is controlled below level 2 (almost no odor), solving the problem of "stuffy smell" after exercise.

[0036] In winter, the insole is flipped over so that the lower fleece layer 301 faces upwards and contacts the foot. The fleece structure forms an air insulation layer, improving the warmth of the foot and shoe. This raises the foot temperature by 3-5°C compared to ordinary insoles, while retaining antibacterial and breathable properties. This allows for adaptability to both sports shock absorption and daily warmth, expanding the product's application range. It offers comprehensive advantages in shock absorption, antibacterial deodorization, and scene adaptability, making it especially suitable for the long-term wear needs of high-intensity sports shoes.
