Description

Technical Field

[0001] This invention belongs to the field of footwear technology, specifically relating to an insole, slippers, and boots. Background Technology

[0002] Safety boots, widely used foot protection equipment in industrial, mining, and construction work environments, must simultaneously meet safety requirements such as impact resistance, puncture resistance, abrasion resistance, and waterproofing. Therefore, their overall structure is typically thick and airtight. During prolonged wear and high-intensity work, the wearer's feet tend to sweat profusely. This sweat is difficult to expel quickly and accumulates inside the boots, leading to dampness, stuffiness, and odor. In severe cases, it can cause blisters, skin irritation, and significantly reduce wearing comfort and work efficiency.

[0003] In the existing technology, conventional work boots mostly use solid insoles, which rely solely on the breathability of the fabric to passively wick away moisture, and cannot alleviate the problem of sweat soaking the feet. Therefore, existing products need to be improved to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an insole, slippers, and boots that solves the technical problem in related technologies where insoles easily accumulate sweat, affecting wearing comfort.

[0005] According to one aspect, at least one embodiment of the present invention provides an insole comprising a body having a plurality of vertically penetrating sweat-wicking holes for discharging sweat downwards. According to an exemplary embodiment of this disclosure, the top and / or bottom of the main body also have a plurality of connecting grooves for connecting the ends of two adjacent sweat vents. The connecting groove located at the top of the main body is used to guide sweat into the sweat vent, and the connecting groove located at the bottom of the main body is used to disperse the sweat discharged from the sweat vent.

[0006] According to an exemplary embodiment of this disclosure, the periphery of the main body is also uniformly provided with a plurality of anti-slip teeth, which are used to abut against the inner wall of the shoe to prevent the main body from shifting. According to an exemplary embodiment of this disclosure, a plurality of the sweat vents are distributed in multiple rows, and the multiple rows of sweat vents are longitudinally connected to each other through the connecting groove.

[0007] According to an exemplary embodiment of this disclosure, the bottom of the main body also has a plurality of blind holes, and the plurality of sweat vents and the plurality of blind holes are spaced apart from each other. The main body can generate a downward airflow by deforming through the blind holes after being squeezed.

[0008] The insole provided in this embodiment of the invention has several vertically penetrating sweat vents on the main body. These sweat vents form a channel that runs through the main body, allowing sweat to be discharged directly downwards along the sweat vents, thus preventing sweat from accumulating on the surface of the main body. The through structure of the sweat vents simplifies the sweat discharge path and improves the sweat discharge efficiency, thereby improving the dampness of the wearing area.

[0009] According to another aspect, at least one embodiment of the present invention also provides a slipper, the slipper further comprising an upper disposed on the top of the main body, the upper having a plurality of vertically penetrating ventilation holes, the ventilation holes also being used for downward leakage of sweat. According to an exemplary embodiment of this disclosure, the shoe upper also has a plurality of guide grooves extending between adjacent anti-slip teeth, the guide grooves being used to guide sweat to flow downward. The slippers provided in this invention are formed by combining the insole and the upper. The ventilation holes on the upper can guide the sweat generated by the foot contacting the upper, allowing the sweat to seep downwards. This achieves comprehensive drainage of sweat in different areas of the foot, solving the problem that the sweat-wicking holes alone cannot cover the sweat in the contact area of ​​the upper. The synergistic effect of the sweat-wicking holes, anti-slip teeth, and ventilation holes enables the slippers to comprehensively and efficiently drain foot sweat while ensuring wearing stability and improving the wearing experience.

[0010] According to another aspect, at least one embodiment of the present invention also provides a boot, the boot further comprising a body and a slipper, the slipper being placed on the inner bottom of the body, the anti-slip teeth abutting against the inner bottom wall of the body, and the upper contacting and engaging with the inner top wall of the body. According to an exemplary embodiment of this disclosure, a plurality of guide strips are uniformly provided on the inner sidewall of the body, and a guide groove for guiding sweat to flow downward is formed between two adjacent guide strips. According to an exemplary embodiment of this disclosure, the bottom of the body has a plurality of through holes, and each through hole is provided with a one-way valve, which is used to discharge sweat to the outside of the body in one direction. According to an exemplary embodiment of this disclosure, a plurality of protrusions are evenly provided on the inner bottom wall of the body, the protrusions being used to support the slippers, and the through holes being located between adjacent protrusions.

[0011] Compared with the prior art, the boots provided in this embodiment of the invention solve the problem of sweat being difficult to expel due to the heavy and sealed nature of the boot body by placing insoles or slippers inside the boot body and utilizing the sweat-wicking and ventilation holes of the insoles or slippers themselves. The anti-slip teeth of the insoles or slippers abut against the inner bottom wall of the body, which can effectively limit the horizontal displacement of the insoles or slippers inside the body, prevent the insoles or slippers from shifting, and ensure that the sweat-wicking and ventilation holes of the insoles or slippers are always aligned with the sweat-prone areas of the feet, ensuring the stable function of sweat wicking. At the same time, the insoles or slippers are placed as independent components inside the body, which is convenient for disassembly and cleaning, and avoids the long-term accumulation of sweat inside the body and the generation of odor. The abutting action of the anti-slip teeth not only ensures the stability of wearing the insoles or slippers, but also does not affect the disassembly and installation of the insoles or slippers, thus achieving a combination of boot sweat-wicking function and ease of use.

[0022] like Figures 1-2 As shown, an insole according to an embodiment of the present invention includes a main body 1, on which a plurality of vertically penetrating sweat-wicking holes 12 are provided. The sweat-wicking holes 12 are used to drain sweat downwards. The main body 1 is the supporting structure of the insole. The sweat-wicking holes 12 are arranged through the thickness direction of the main body 1, forming a vertically penetrating channel. When sweat comes into contact with the upper surface of the main body 1, the sweat can move downwards along the penetrating path of the sweat-wicking holes 12, and the sweat is discharged from the upper side of the main body 1 to the lower side of the main body 1 through the sweat-wicking holes 12, thus completing the sweat drainage process.

[0023] The insole provided in this embodiment has several vertically penetrating sweat vents 12 on the main body 1. The sweat vents 12 form a channel that runs through the main body 1, allowing sweat to be discharged directly downwards along the sweat vents 12, thus preventing sweat from accumulating on the surface of the main body 1. The through structure of the sweat vents 12 simplifies the sweat discharge path and improves the sweat discharge efficiency, thereby improving the dampness of the wearing area.

[0024] Furthermore, the top and bottom of the main body 1 also have several connecting grooves 13. The upper and lower ends of adjacent sweat vents 12 are connected through the connecting grooves 13. The connecting grooves 13 located at the top of the main body 1 are used to guide sweat into the sweat vents 12, and the connecting grooves 13 located at the bottom of the main body 1 are used to disperse the sweat discharged. The connecting grooves 13 are respectively opened on the top surface and the bottom surface of the main body 1, and each connecting groove 13 is connected to two or more adjacent sweat vents 12, forming a channel structure of top convergence and bottom divergence. When sweat comes into contact with the top of the main body 1, the connecting grooves 13 at the top collect the sweat dispersed at different positions on the top of the main body 1, guide the sweat into each sweat vent 12 connected to it, and after the sweat moves down along the sweat vents 12 to the bottom of the main body 1, the connecting grooves 13 at the bottom disperse the sweat discharged from the sweat vents 12 to different areas on the bottom of the main body 1, completing the process of sweat convergence, guidance and dispersion discharge.

[0025] The insole provided in this embodiment has several connecting grooves 13 set at the top and bottom of the main body 1, and the upper and lower ends of adjacent sweat vents 12 are connected through the connecting grooves 13. The connecting grooves 13 at the top can collect the sweat dispersed on the top of the main body 1, avoiding the sweat from stagnating locally on the top of the main body 1, and ensuring that the sweat can enter the sweat vents 12 efficiently. This solves the problem that a single sweat vent 12 can only guide the sweat in the surrounding area and has a limited sweat venting range. The connecting grooves 13 at the bottom can disperse the sweat discharged from the sweat vents 12, avoiding the sweat from accumulating locally at the bottom of the main body 1, and further accelerating the subsequent diffusion and discharge speed of the sweat. The cooperation between the sweat vents 12 and the connecting grooves 13 forms a complete sweat venting structure of "top convergence - middle venting - bottom diversion". Compared with a single sweat vent 12, it significantly expands the sweat venting range, improves the uniformity and efficiency of sweat discharge, and further improves the dampness of the wearing area.

[0026] Furthermore, the periphery of the main body 1 is evenly provided with several anti-slip teeth 14, which can prevent the main body 1 from shifting after being squeezed. The anti-slip teeth 14 are evenly distributed along the periphery of the main body 1, protruding from the side of the main body 1, and the extension direction of the anti-slip teeth 14 is consistent with the thickness direction of the main body 1. When the main body 1 is placed inside the wearable carrier, the main body 1 is squeezed by the foot during the wearing process. The anti-slip teeth 14 contact the inner wall of the wearable carrier and generate a resisting force. The resisting force restricts the displacement of the main body 1 in the horizontal direction inside the wearable carrier, thereby preventing the main body 1 from shifting and ensuring that the sweat vents 12 can always correspond to the sweat-prone area of ​​the foot, maintaining the stability of the sweat wicking function.

[0027] The insole provided in this embodiment has several anti-slip teeth 14 evenly arranged around the periphery of the main body 1. The anti-slip teeth 14, when compressed, generate a resistance force against the inner wall of the wearable carrier, which can effectively limit the horizontal displacement of the main body 1 inside the wearable carrier and prevent the main body 1 from deviating. If the main body 1 deviates, the sweat vents 12 will be deviated from the sweat-prone areas of the foot, reducing the sweat drainage efficiency. The anti-slip teeth 14 ensure that the sweat vents 12 are always aligned with the sweat-prone areas of the foot, ensuring the stable function of the sweat vents 12. At the same time, the anti-slip teeth 14 are evenly distributed around the periphery of the main body 1, so that the limiting force of the main body 1 is uniform in all directions, avoiding the tilting of the main body 1 caused by uneven local force, further improving the stability of the insole and indirectly ensuring the continuity of sweat drainage.

[0028] Furthermore, the bottom of the main body 1 also has several blind holes 15, and several sweat vents 12 are distributed around the blind holes 15. The main body 1 can generate airflow through the blind holes 15 when it is compressed. The blind holes 15 are located at the bottom of the main body 1 and do not penetrate the main body 1. The openings of the blind holes 15 face downwards from the main body 1. Several sweat vents 12 are evenly distributed around each blind hole 15. When the wearer walks or stands, the foot compresses the main body 1, causing the main body 1 to deform. The air inside the blind holes 15 is squeezed out. When the foot pressure is released and the main body 1 returns to its deformed state, a negative pressure is formed inside the blind holes 15, and external air is drawn in. In this process, airflow is formed. The airflow can drive the air circulation around the sweat vents 12, assisting the sweat vents 12 in expelling sweat downwards, while accelerating the evaporation rate of sweat.

[0029] The insole provided in this embodiment has several blind holes 15 at the bottom of the main body 1, and sweat-wicking holes 12 are distributed around the blind holes 15. During the compression and repositioning of the main body 1, the blind holes 15 can assist in generating airflow. The airflow can accelerate the air circulation around the sweat-wicking holes 12. On the one hand, it can drive the sweat in the sweat-wicking holes 12 to move downward quickly, improving the sweat-wicking efficiency of the sweat-wicking holes 12. On the other hand, it can accelerate the evaporation of the sweat discharged to the bottom of the main body 1, avoiding the accumulation of sweat at the bottom of the main body 1. The cooperation between the sweat-wicking holes 12 and the blind holes 15 combines the "active guidance" and "assisted evaporation" of sweat. Compared with a single sweat-wicking hole 12, it further improves the moisture-wicking effect of the main body 1 and reduces the damp and stuffy feeling of the wearing area. At the same time, the setting of the blind holes 15 does not affect the through structure of the sweat-wicking holes 12. The two work together to improve the overall sweat-wicking and moisture-wicking performance of the insole without increasing the structural complexity of the main body 1.

[0030] refer to Figure 3 In one possible implementation, a slipper 2 is also proposed. The slipper 2 includes an insole and an upper 21 disposed on the top of the main body 1. The upper 21 has several vertically penetrating ventilation holes 211 for downward leakage of sweat. When the wearer wears the slipper 2, part of the sweat on the feet directly contacts the top of the main body 1 and is discharged downward through the sweat-draining holes 12 on the main body 1. The other part contacts the inner wall of the upper 21 and leaks downward along the ventilation holes 211 on the upper 21. The leaked sweat falls from the sweat-draining holes 12 on the top of the main body 1 or the groove between adjacent anti-slip teeth 14 to the bottom of the main body 1.

[0031] In this embodiment, the slipper 2 is formed by combining the insole and the upper 21. The ventilation holes 211 on the upper 21 can guide the sweat generated by the foot contacting the upper 21 and allow the sweat to seep downwards, thus achieving comprehensive drainage of sweat in different areas of the foot. This solves the problem that the sweat venting holes 12 of the main body 1 cannot cover the sweat in the contact area of ​​the upper 21. The synergistic effect of the sweat venting holes 12, the anti-slip teeth 14 and the ventilation holes 211 enables the slipper 2 to comprehensively and efficiently drain foot sweat while ensuring wearing stability and improving the wearing experience of the slipper 2.

[0032] Furthermore, the upper 21 also has several guide grooves 212 extending between adjacent anti-slip teeth 14, which are used to guide sweat downwards. The guide grooves 212 are formed on the inner wall of the upper 21, with one end extending to the top edge of the upper 21 and the other end extending to the gap between two adjacent anti-slip teeth 14, communicating with the top surface of the main body 1; when sweat comes into contact with the inner wall of the upper 21, part of the sweat seeps directly downwards through the vent 211 to the top of the main body 1, and the other part of the sweat flows downwards along the guide grooves 212, flowing through the gap between adjacent anti-slip teeth 14 to the bottom of the main body 1.

[0033] In this embodiment, by providing a guide groove 212 extending between adjacent anti-slip teeth 14 on the shoe upper 21, the guide groove 212 can directionally guide the sweat on the inner wall of the shoe upper 21, so that the sweat can flow quickly along the guide groove 212 to the top of the main body 1, avoiding the problem of sweat accumulating on the inner wall of the shoe upper 21 and dripping poorly; the guide groove 212 extends between adjacent anti-slip teeth 14, using the gap between the anti-slip teeth 14 as the sweat outlet, preventing the sweat from flowing to the top of the main body 1, and relieving the sweat venting pressure of the sweat venting hole 12 at the top of the main body 1.

[0034] refer to Figures 4-5 In one possible implementation, a boot is also proposed, which can contain either an insole or the entire slipper 2. The boot includes a body 3, with the slipper 2 placed inside the inner bottom of the body 3, and anti-slip teeth 14 abutting against the inner bottom wall of the body 3. The body 3 is the supporting structure of the boot, forming a chamber to accommodate the foot and the slipper 2. When the slipper 2 is placed inside the inner bottom of the body 3, the bottom of the insole body 1 is in contact with the inner bottom wall of the body 3, and the anti-slip teeth 14 around the insole abut against the inner bottom wall of the body 3, generating a resisting force. When the wearer wears the boot, the foot is located inside the upper 21 of the slipper 2, and sweat is discharged downwards to the inner bottom wall of the body 3 through the ventilation holes 211 of the upper 21 and the sweat-draining holes 12 of the insole. The anti-slip teeth 14, by abutting against the inner bottom wall of the body 3, limit the slipper 2 from shifting inside the body 3, ensuring that the slipper 2 is always located in the preset position inside the body 3, maintaining the stability of the sweat drainage process.

[0035] In this embodiment, by placing the insole or slipper 2 inside the bottom of the boot body 3, the sweat-wicking holes 12 and ventilation holes 211 of the insole or slipper 2 are used to achieve initial sweat drainage, solving the problem of sweat being difficult to expel due to the thick and sealed nature of the boot body 3. The anti-slip teeth 14 of the insole or slipper 2 abut against the inner bottom wall of the body 3, which can effectively limit the horizontal displacement of the insole or slipper 2 inside the body 3, prevent the insole or slipper 2 from shifting, and ensure that the sweat-wicking holes 12 and ventilation holes 211 of the insole or slipper 2 are always aligned with the sweat-prone areas of the feet, ensuring the stable function of sweat drainage. At the same time, the insole or slipper 2 is placed inside the body 3 as an independent component, which is easy to disassemble and clean, and avoids the long-term accumulation of sweat inside the body 3 and the generation of odor. The abutting action of the anti-slip teeth 14 not only ensures the stability of wearing the insole or slipper 2, but also does not affect the disassembly and installation of the insole or slipper 2, thus achieving a combination of boot sweat-wicking function and ease of use.

[0036] Furthermore, a plurality of guide strips 31 are evenly provided on the inner sidewall of the main body 3. The guide strips 31 are used to guide sweat to flow downward. The main body 3 is the load-bearing structure of the boot. The guide strips 31 are evenly distributed along the inner sidewall of the main body 3, and the extension direction is consistent with the height direction of the main body 3. One end is close to the top opening of the main body 3, and the other end extends to the inner bottom wall of the main body 3, corresponding to the edge of the upper 21 of the slipper 2. When the wearer wears the boot, part of the sweat on the feet is discharged to the inner bottom wall of the main body 3 through the ventilation holes 211 and sweat vents 12 of the slipper 2, and the other part adheres to the inner sidewall of the main body 3 and flows downward along the guide strips 31 to the inner bottom wall of the main body 3.

[0037] In this embodiment, by uniformly arranging guide strips 31 on the inner sidewall of the main body 3, the guide strips 31 can directionally guide the sweat adhering to the inner sidewall of the main body 3, so that the sweat flows quickly downward along the guide strips 31 to the inner bottom wall of the main body 3, avoiding the problem of sweat accumulating on the inner sidewall of the main body 3 and being unable to be discharged; the guide strips 31 work together with the sweat venting holes 12, ventilation holes 211, and anti-slip teeth 14 of the slipper 2 to expand the range of sweat drainage inside the boot, including the sweat that comes into contact with the slipper 2 and the inner sidewall of the main body 3, further improving the sweat venting efficiency of the boot and improving the humid environment inside the boot.

[0038] Furthermore, the bottom of the main body 3 has several through holes 32, each of which is equipped with a one-way valve. The one-way valve is used to discharge sweat to the outside in one direction. The one-way valve can be, for example, a Tesla valve, which only allows sweat inside the main body 3 to be discharged to the outside of the main body 3, and prevents external impurities from entering the interior of the main body 3. When the wearer wears the boots, the sweat on the feet is discharged to the inner bottom wall of the main body 3 through the ventilation holes 211 and sweat vents 12 of the slippers 2. The sweat accumulated at the bottom of the main body 3 is discharged to the outside of the main body 3 through the one-way valve in the through hole 32. At the same time, the airflow generated when the main body 1 is squeezed can also be discharged through the one-way valve to accelerate the evaporation of sweat.

[0039] In this embodiment, by setting a through hole 32 at the bottom of the main body 3 and installing a one-way valve in the through hole 32, the one-way valve can realize the one-way discharge of sweat to the outside of the main body 3. This ensures that the sweat accumulated inside the main body 3 can be quickly discharged to the outside, while preventing external dust, water stains and other impurities from entering the inside of the main body 3, and preventing impurities from clogging the sweat vent 12, the ventilation hole 211 or polluting the internal environment of the main body 3. The cooperation between the through hole 32 and the one-way valve provides a direct discharge channel for the sweat inside the main body 3, solving the problem of sweat accumulating at the bottom of the main body 3 and not being able to be discharged. Together with the sweat vent 12, ventilation hole 211 and anti-slip teeth 14 of the slipper 2, a complete process of "sweat collection - internal drainage - external discharge" is formed, which significantly improves the sweat wicking efficiency of the boot. At the same time, the one-way sealing function of the one-way valve ensures the waterproof and dustproof performance of the boot, taking into account both sweat wicking function and protective performance.

[0040] Furthermore, several protrusions are evenly distributed on the inner bottom wall of the main body 3, which are used to support the slipper 2. The protrusions are evenly distributed on the inner bottom wall of the main body 3 and protrude from the surface of the inner bottom wall of the main body 3. When the slipper 2 is placed on the inner bottom of the main body 3, the protrusions contact the bottom of the insole body 1, providing support for the slipper 2. When the wearer wears boots, the foot pressure is transmitted to the protrusions through the slipper 2. The protrusions support the slipper 2 and create a gap between the slipper 2 and the inner bottom wall of the main body 3. Sweat is discharged through the sweat vents 12 of the slipper 2 and enters this gap, and then is discharged through subsequent structures.

[0041] In this embodiment, protrusions are evenly distributed on the inner bottom wall of the main body 3. These protrusions provide stable support for the slipper 2, creating a gap between the slipper 2 and the inner bottom wall of the main body 3. This expands the space for the temporary storage and flow of sweat discharged through the vent holes 12, preventing sweat from directly adhering to the inner bottom wall of the main body 3 and causing poor drainage. At the same time, the gap promotes air circulation and accelerates sweat evaporation. The even distribution of the protrusions ensures that the slipper 2 is subjected to uniform force, preventing tilting or damage caused by uneven force distribution in certain areas, and improving the wearing stability of the slipper 2. The protrusions work in conjunction with the anti-slip teeth 14 of the slipper 2 to ensure the support stability of the slipper 2 and prevent it from slipping off course. In addition, in conjunction with the vent holes 12 and ventilation holes 211 of the slipper 2, the sweat discharge path is further optimized, improving the sweat wicking and moisture dissipation effect of the boot and improving the humid and stuffy environment inside the boot.

[0042] In addition, mugwort, bamboo charcoal, antibacterial agents, etc. can be mixed into the insoles, slippers, and boots to achieve the functions of insect prevention, deodorization, and sterilization.
