[0002] Traditional insoles are mostly made of materials such as ethylene acetate copolymer (EVA), polyurethane (PU) or memory foam. Although they have a certain cushioning performance, they have obvious defects in actual use.

[0003] Traditional insoles lack sufficient sweat absorption, failing to effectively manage the large amounts of sweat produced by the feet. This results in feet remaining in a damp and hot environment, promoting bacterial growth and odor. Furthermore, their antibacterial coatings are prone to peeling off during daily use, making long-lasting antibacterial effects difficult to achieve. Simultaneously, due to limitations in their structural design, traditional insoles are prone to deformation after prolonged pressure or frequent use, affecting comfort and support. They fail to meet the demands for insoles that are highly absorbent, provide long-lasting odor control, are easy to maintain, and are ergonomically designed for both sports and everyday use. Therefore, there is an urgent need to develop a new type of insole to overcome the shortcomings of traditional insoles. Utility Model Content

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] The following reference Figures 1 to 4 This invention describes a deodorizing and sweat-absorbing insole provided according to some embodiments of the present invention.

[0034] Some embodiments of this application provide an odor-reducing and sweat-wicking insole.

[0035] like Figures 1 to 2As shown, a deodorizing and sweat-wicking insole includes an insole body. The insole body comprises a skin-friendly antibacterial layer 1, a sweat-absorbing and deodorizing layer 2, and a support and cushioning layer 3, which are sequentially bonded together in a vertical direction. Specifically, the insole body adopts a layered structure. The skin-friendly antibacterial layer 1 directly adheres to the foot, inhibiting bacteria and reducing friction. The sweat-absorbing and deodorizing layer 2 is located in the middle layer and can absorb and decompose foot sweat and odor. The support and cushioning layer 3 provides stable support and relieves walking pressure.

[0036] The insole body includes a forefoot portion, an arch portion, and a heel portion arranged sequentially along the shape of the foot. In a preferred embodiment, the forefoot and arch portions are provided with a breathable structure, which penetrates the skin-friendly antibacterial layer 1, the sweat-absorbing and deodorizing layer 2, and the support and cushioning layer 3. The insole body also includes a raised structure, which is provided in the forefoot and heel portions. The raised structure includes at least two raised portions, which are arranged at intervals. The division of the forefoot, arch, and heel portions conforms to the shape of the human foot. The breathable structure penetrates all three layers, promoting air circulation and keeping the inside of the insole dry.

[0037] like Figure 1 As shown, the spaced protrusions of the raised structure enhance friction with the sole of the foot, preventing slippage, and simultaneously providing a massage effect to specific areas of the foot. In actual use, the layers work together: the skin-friendly antibacterial layer 1 resists bacteria, the sweat-absorbing and deodorizing layer 2 treats moisture and odor, the support and cushioning layer 3 disperses pressure, the breathable structure ensures air circulation, and the raised structure enhances the anti-slip and massage effects, thus allowing users to keep their feet comfortable and reduce discomfort during exercise or daily activities.

[0038] More specifically, such as Figure 4 As shown, the breathable structure includes at least two groups of breathable holes, arranged in a specified direction, with the breathable holes 6 in the two groups either staggered or neatly arranged. The breathable structure consists of at least two groups of breathable holes arranged in a specified direction, with the breathable holes 6 within each group either staggered or neatly arranged. This design increases the breathable area, promotes air circulation inside the insole, quickly removes heat and moisture from the feet, and keeps them dry. Furthermore, the staggered arrangement of the breathable holes 6 more effectively promotes air convection, while the neatly arranged holes 6 are easier to manufacture and ensure a certain level of breathability. Regardless of the arrangement, the breathable structure operates efficiently, improving the internal environment of the insole and reducing bacterial growth and odor.

[0039] Preferably, the ventilation hole group includes a plurality of ventilation holes 6, which can be arranged at equal intervals. The equal distribution of ventilation holes 6 within the ventilation hole group ensures uniform ventilation, allowing good ventilation in all parts of the insole, evenly expelling moisture from the feet, and preventing localized sweat accumulation.

[0040] The evenly spaced arrangement also facilitates production, processing, and quality control, ensuring the consistency and stability of the ventilation hole group. In actual use, the evenly distributed ventilation holes 6 can continuously provide ventilation, maintain smooth airflow, reduce stuffiness and dampness in the feet, improve wearing comfort, and help extend the lifespan of the insole.

[0041] Preferred, again Figure 3 Along the axial direction of the vent 6, the pore size of the vent 6 at the support buffer layer 3 is larger than its pore size at the sweat-absorbing and deodorizing layer 2, so that the vent 6 presents a trapezoidal shape with a wider top and a narrower bottom in the longitudinal section.

[0042] Specifically, such as Figure 4 As shown, the ventilation holes 6 are designed in a trapezoidal shape, wider at the top and narrower at the bottom. The large pores in the support and buffer layer 3 facilitate rapid airflow, while the small pores in the sweat-absorbing and deodorizing layer 2 prevent foreign objects from entering and guide sweat absorption. This shape optimizes the airflow path and enhances breathability.

[0043] More specifically, the forefoot portion is provided with a first protruding structure 4, which is sandwiched between two groups of ventilation holes. Specifically, in the forefoot portion, the first protruding structure 4 is located between the two groups of ventilation holes. This design allows the ventilation holes to accelerate airflow during use, reducing stuffiness in the feet, while the first protruding structure 4 provides support and massage to specific areas of the foot during walking, promoting blood circulation. The two work together to provide both good breathability and comfortable support for the foot, effectively relieving foot fatigue caused by prolonged walking or exercise, further enhancing the functionality and comfort of the insole.

[0044] In a preferred embodiment, such as Figure 1-2 As shown, the first protruding structure 4 is distributed in a streamlined or wavy shape. Preferably, the first protruding structure 4 is designed to be streamlined or wavy, which better conforms to the physiological curve of the foot and allows for more natural contact with the foot during walking, reducing local pressure.

[0045] Of course, the first protrusion structure 4 can also be distributed in a dotted pattern.

[0046] Furthermore, the first raised structure 4 extends along the undulating surface of the skin-friendly antibacterial layer 1, and is positioned along the length of the insole body. When the first raised structure 4 extends along the undulating surface of the skin-friendly antibacterial layer 1, it can provide different levels of support based on the varying pressure on different parts of the foot, thus improving comfort. When it extends along the length of the insole body, it can continuously provide support and massage during the forward and backward movement of the foot. Whether using a single method or a combination of methods, the effect of the first raised structure 4 on the foot can be optimized, allowing the foot to receive more fitting and stable support and massage during exercise or walking, reducing relative slippage between the foot and the insole.

[0047] Furthermore, such as Figure 1 As shown, Figure 1 The image shows the front of the insole body, which is the area where the foot directly contacts the insole when worn. The first raised structure 4 can be positioned between the skin-friendly antibacterial layer 1 and the sweat-absorbing and deodorizing layer 2. This allows it to contact the foot through the skin-friendly antibacterial layer 1, providing support and massage functions, while the sweat-absorbing and deodorizing layer 2 absorbs sweat from the contact area, keeping it dry. This design avoids wear caused by direct exposure of the raised structure, extending its lifespan and ensuring close cooperation between the layers. In actual use, the skin-friendly antibacterial layer 1 transmits foot pressure to the first raised structure 4, which provides cushioning and support, while the sweat-absorbing and deodorizing layer 2 treats sweat odor. The three work together to significantly improve the insole's performance in the forefoot area.

[0048] Specifically, the sweat-absorbing and deodorizing layer 2 is further provided with a configuration area, which is recessed along the direction of the sweat-absorbing and deodorizing layer 2 toward the supporting buffer layer 3, and the first protruding structure 4 is disposed in the configuration area. Specifically, as... Figure 2 As shown, the sweat-absorbing and deodorizing layer 2 has a recessed area for accommodating the first protruding structure 4. This design makes the first protruding structure 4 more firmly bonded to the sweat-absorbing and deodorizing layer 2, preventing displacement during use. Simultaneously, the recessed area accommodates the protruding structure, making the insole surface relatively flat and reducing the feeling of foreign objects on the feet. The properties of the sweat-absorbing and deodorizing layer 2 can also be better utilized around the first protruding structure 4 through the designated area, enhancing the treatment of sweat and odor in that area. In use, the first protruding structure 4 functions stably within the designated area, and the sweat-absorbing and deodorizing layer 2 efficiently treats moisture and odor, jointly ensuring comfortable and dry feet.

[0049] More specifically, such as Figure 3As shown, a second protruding structure 5 is provided at the heel, and the second protruding structure 5 is approximately circular. Specifically, the second protruding structure 5 at the heel of the insole body is approximately circular. This shape can evenly distribute the pressure on the heel and avoid excessive local pressure. When the heel contacts the insole, the second protruding structure 5 acts as a cushioning support, reducing the impact force during walking or running and protecting the heel joint and tissues. Its protruding design also increases the friction between the heel and the insole, preventing the heel from slipping and improving walking stability. In daily activities, the second protruding structure 5 continuously provides cushioning support for the heel, distributing pressure, reducing vibration, and effectively relieving fatigue and damage to the heel caused by prolonged standing or exercise.

[0050] In a preferred embodiment, the insole body is wrapped from the support and cushioning layer 3 toward the sweat-absorbing and deodorizing layer 2, and in the wrapped state, the edge portion of the insole body is bent toward the center portion of the insole body.

[0051] Specifically, the insole body adopts a wrap-around design, with the edge of the support and cushioning layer 3 bending towards the sweat-absorbing and deodorizing layer 2 to form a wrap-around structure. This allows the insole to better conform to the contours of the foot, enhance the wrap-around feel, reduce relative movement with the foot, and improve stability during use.

[0052] Meanwhile, the tightly integrated wrapping structure enhances the overall strength and durability of the insole. During use, the insole remains firmly fixed inside the shoe, preventing shifting regardless of the activity. The folded edges also protect the edges of the foot from friction and pressure from the shoe's edges, improving comfort and safety.

[0053] See you again Figure 3 The image shows the back of the insole, which is in a wrapped state. To prevent the insole from being squeezed and folded when stepped on, multiple through grooves 7 can be provided on the insole body to provide space for the material of the insole body to release when it is squeezed, thereby improving wearing comfort.

[0054] In a preferred embodiment, the forefoot portion of the support cushioning layer is made of melamine foam with a first density, and the heel portion of the support cushioning layer is made of melamine foam with a second density greater than the first density.

[0055] The forefoot and arch portions of the support and cushioning layer are made of low-density melamine foam with a density of 60 kg / m³, preferably 3 mm thick. This provides soft cushioning for the forefoot and allows the arch portion to adapt to the flexion of the foot. The heel portion of the support and cushioning layer is made of melamine foam modified by mixing EVA and melamine resin, preferably with a density of 90 kg / m³ and a thickness of 5 mm. This heel design provides better support and reduces impact on the Achilles tendon during running. The forefoot, arch, and heel portions are connected by a gradient density design, which better disperses plantar pressure and reduces exercise fatigue.

[0056] In a preferred embodiment, the thickness of the skin-friendly antibacterial layer 1 is 0.5mm-5mm. Preferably, the thickness of the skin-friendly antibacterial layer 1 is 0.5mm-1mm. The micro-protrusion design reduces friction (height 0.1mm-0.3mm) and prevents blisters and skin abrasion; the material is a silver ion antibacterial fabric, such as silver ion modified polyester fiber, which utilizes silver ions (Ag... + It disrupts bacterial cell membranes and interferes with DNA replication, achieving broad-spectrum antibacterial activity, while the hydrophilic treatment of the fiber surface (contact angle θ≈60°) accelerates sweat penetration;

[0057] The thickness of the sweat-absorbing and deodorizing layer 2 is 0.5mm-5mm. Preferably, its thickness is 2mm-3mm, and it is made by gradient impregnation of melamine foam loaded with titanium dioxide (TiO2) and activated carbon (mass ratio 1:2-1:5), with a porosity ≥80% and a liquid absorption rate ≥500%. The melamine foam can quickly absorb and store sweat, preventing foot dampness. Under ultraviolet or visible light excitation, TiO2 generates active oxygen (·OH, O2). - The activated carbon decomposes organic odor molecules into CO2 and H2O; it acts as an adsorbent to capture organic molecules (such as urea and lactic acid) in sweat and provides a high specific surface area substrate for TiO2, increasing the photocatalytic reaction interface, so that the overall structure of the foam can also maintain air circulation and avoid the growth of bacteria in a stuffy environment.

[0058] The thickness of the support and cushioning layer 3 is 0.5mm-5mm. Preferably, its thickness is 3mm-5mm. The forefoot and arch portions of the support and cushioning layer are made of low-density melamine foam with a density of 60kg / m³. Preferably, its thickness is 3mm. The heel portion of the support and cushioning layer is made of melamine foam modified by mixing EVA and melamine resin, with a preferred density of 90kg / m³ and a preferred thickness of 5mm.

[0059] This design results in an insole body that features a skin-friendly moisture-wicking layer, a sweat-absorbing layer that absorbs / decomposes sweat, and a support layer that disperses pressure, forming a closed loop of "channeling-purification-buffering." The thickness of each layer is set within a reasonable range, ensuring the insole combines functionality with appropriate thickness and softness. The thickness of the skin-friendly antibacterial layer 1 ensures comfort and antibacterial properties in contact with the foot; the thickness of the sweat-absorbing and deodorizing layer 2 ensures sufficient space and material to handle sweat odor; and the thickness of the support and cushioning layer 3 provides stable support and good cushioning. The insole body, combined with the special shape of the ventilation holes 6, achieves a balance in breathability, sweat absorption, and support, providing users with a comfortable, healthy, and stable wearing experience.

[0060] In this invention, the materials of each layer can be prepared in the following ways.

[0061] (I) Preparation of Skin-Friendly Antibacterial Layer 1

[0062] Silver ion-modified polyester fiber was selected as the material for the skin-friendly antibacterial layer 1. The specific preparation steps are as follows:

[0063] 1. Pretreatment: Immerse the polyester fiber base fabric in a 5% NaOH solution at 60℃ for 10 minutes to remove impurities from the base fabric surface and activate the hydroxyl groups on the fiber surface to enhance the subsequent silver ion loading effect.

[0064] 2. Silver ion loading: The pretreated base fabric is immersed in an AgNO3 solution at 60°C for 30 minutes using an impregnation method, allowing the Ag ions to be loaded. + The silver ion solution can be adsorbed onto the fiber surface via ion exchange; alternatively, a spraying method can be used, where a device with a pressure of 0.3 MPa and a flow rate of 2 mL / min is used to uniformly spray the silver ion solution onto the base fabric surface.

[0065] 3. Reduction and Curing: Immerse the silver-loaded fabric in a 5% NaBH4 solution at room temperature for 5 minutes to allow the Ag... + It is reduced to silver nanoparticles.

[0066] 4. Washing and drying: Rinse the fabric three times with deionized water to remove residual solution, then dry and set at 80℃, controlling the silver ion loading at 0.5-1.0mg / g.

[0067] On the surface of the skin-friendly antibacterial layer 1 after the above treatment, a micro-protrusion structure with a height of 0.1mm-0.3mm is formed by a precision mold imprinting process to reduce the coefficient of friction with the feet and prevent blisters and skin abrasion.

[0068] (II) Preparation of sweat-absorbing and deodorizing layer 2

[0069] Melamine foam was selected as the substrate and cut into sheets with a thickness of 2mm-3mm. A gradient impregnation method was used to load titanium dioxide (TiO2) and activated carbon composites. The specific process is as follows:

[0070] 1. Preparation of material solution

[0071] First impregnation solution: 3% TiO2 sol with a particle size of 20nm and 9% activated carbon powder with a particle size of 5μm are added to an ethanol solution and dispersed by ultrasonication to prepare a uniform first impregnation solution.

[0072] Second impregnation solution: 5% TiO2 sol with a particle size of 20nm and 15% activated carbon are added to an ethanol solution and dispersed by ultrasonication to obtain the second impregnation solution.

[0073] 2. Staged impregnation

[0074] First impregnation: Immerse the melamine foam in the first impregnation solution and maintain it under a vacuum of -0.1MPa for 15 minutes to ensure that the solution fully penetrates into the foam macropores (pore size 50μm-200μm). Then, pre-dry it at 60℃ for 20 minutes to form the primary functional layer.

[0075] Second impregnation: The pre-treated foam is immersed in the second impregnation solution for 10 minutes under normal pressure. The solution fills the small pores of the foam (pore diameter 10μm-50μm) by capillary action. Finally, it is dried and shaped at 80℃ for 30 minutes to make the mass ratio of TiO2 to activated carbon reach 1:3 and uniformly loaded on the surface of the melamine foam skeleton, thus obtaining a sweat-absorbing and deodorizing layer 2 with a porosity ≥80% and a liquid absorption rate ≥500%.

[0076] (III) Preparation of Support Buffer Layer 3

[0077] The support and buffer layer 3 is designed with a gradient composite structure, and is specifically fabricated in the forefoot and heel areas respectively:

[0078] 1. Forefoot area: Select low-density melamine foam with a density of 60kg / m³, cut into sheets with a thickness of 3mm, to provide soft cushioning for the foot and adapt to the arch flexion.

[0079] 2. Heel area: EVA and melamine resin are mixed in a specific ratio and then processed through a modified foaming process to create melamine foam with a density of 90kg / m³ and a thickness of 5mm, which enhances heel support and reduces impact on the Achilles tendon during running.

[0080] 3. Transition layer composite: The forefoot and heel preforms are spliced ​​together and hot-pressed to achieve seamless bonding under certain temperature and pressure, forming a continuous gradient support structure.

[0081] During overall assembly: The prepared skin-friendly antibacterial layer 1, sweat-absorbing and deodorizing layer 2, and supporting and buffering layer 3 are bonded together using water-based polyurethane hot melt adhesive. A roller coating device is used to evenly apply the hot melt adhesive to the surface of each layer, with the coating amount controlled at 20g / m². 2 Then, through a hot pressing process, the three layers are held at 120℃ and 0.5MPa for 30 seconds to achieve a tight bond.

[0082] To ensure the self-supporting cushioning layer 3 of the insole wraps around the sweat-absorbing and deodorizing layer 2, the edges of the insole are bent towards the center of the insole after the interlayer bonding. The bending angle is set according to actual needs. Finally, a 0.1mm thick TPU film is used to cover the edges of the insole, and a hot air welding process is used to firmly connect the TPU film to the insole edges, forming a sealed edge and improving the durability and comfort of the insole.

[0083] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0084] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
