[0028] With reference to FIGS. 1 to 10, a shoe includes a shoe upper 100 and a sole 200, where the sole 200 is connected to the shoe upper 100. A wearing space 300 between the shoe upper 100 and the sole 200.

[0029] The sole 200 includes a sole body 210 and a supporting insole 230. An airflow distributing device 220 is defined inside the sole body, which is configured to expel air inside the shoe to an outside of the shoe. A bottom of the sole body 210 is provided with an exhaust port 211, and the airflow distributing device 220 expels the warm, humid air through the exhaust port 211 while also accelerating an air circulation rate.

[0030] The supporting insole 230 is positioned within the wearing space 300, and provided with air guiding mesh grooves 231 that redistributes an airflow introduced into the wearing space 300 by the airflow distributing device 220.

[0031] During use, the shoe forms the wearing space 300 by combining the shoe upper 100 with the sole 200. The airflow distributing device 220 within the sole 200 facilitates air circulation and expels warm, humid air from inside the shoe, improving comfort by addressing the traditional issues of stuffiness and dampness caused by insufficient breathability in conventional footwear. The airflow distributing device 220 actively drives forced exhaust, making air exchange efficient regardless of external environmental conditions and actively creating an airflow path: external environment.fwdarw.shoe air (containing sweat evaporation and humid gases).fwdarw.air inlet of the airflow distributing device.fwdarw.airflow distributing device pressurizes and accelerates.fwdarw.air outlet of the sole.fwdarw.external environment.

[0032] It is important to note that the airflow distributing device 220 first creates a localized negative pressure within the wearing space 300, drawing air out of the wearing space 300 and causing the external air to flow into the wearing space 300. The exhaust port 211 on the bottom of the sole 200 is more effective at expelling warm, humid air from the wearing space 300. The core of this disclosure is to establish an active and efficient foot ventilation and heat dissipation system, significantly enhancing dryness and comfort. The working principle is as follows: the airflow distributing device 220 inside the sole body 210 acts as the primary driving force. It actively expels the accumulated humid air from the wearing space 300 through the exhaust port 211 while significantly accelerating the air circulation rate both inside and outside the shoe, creating a powerful active ventilation effect. Simultaneously, external dry air is naturally drawn into the shoe. The supporting insole 230 inside the wearing space 300 plays a key role in optimizing airflow distribution. The air guiding mesh grooves 231 on the surface of the insole redistributes the incoming airflow to ensure it covers the entire footbed area evenly, eliminating ventilation dead zones, and maximizing the removal of foot heat and moisture, providing a comprehensive and continuous dry foot experience.

[0033] In short, this system combines the active exhaust acceleration from the airflow distributing device 200 with the even airflow distribution of the supporting insole 230, creating an efficient and circulating foot microclimate regulation environment. It should be noted that the exhaust port 211 on the bottom of the sole body 210 is more conducive to expelling warm, humid air and sweat.

[0034] In this embodiment, the supporting insole 230 is provided with ventilation holes 232, one end of which communicates with the wearing space 300. The supporting insole 230 includes an insole surface 233, on which supporting protrusions 234 are arranged. The supporting protrusions 234 are fixedly connected to the insole surface 233, and together with the insole surface 233 form an air guiding mesh network 231. The supporting protrusions 234 are configured to support the user's foot, while the air guiding mesh network 231 forms an airflow passage to redistribute the air drawn in from the external environment. This allows the air drawn from the external environment to be more evenly dispersed under the user's foot through the air guiding mesh network 231.

[0035] When in use, the supporting insole 230, by defining the ventilation holes 232, establishes direct communication with the wearing space 300, ensuring that fresh air introduced from the outside can smoothly enter the insole structure. The key point lies in the supporting protrusions 234 fixedly disposed on the insole surface 233. On one hand, the supporting protrusions 234 provide physical support to the user's foot, dispersing pressure and improving comfort and stability. On the other hand, the supporting protrusions 234, together with the insole surface 233, constitute a three-dimensional distribution of the air guiding mesh network 231. This mesh-like channel system undertakes the crucial function of secondary airflow distribution: it efficiently and uniformly directs and disperses the air drawn from the external environment across the entire plantar region. This design significantly eliminates ventilation dead zones, ensuring that cool and dry air can fully contact various parts of the sole (such as the forefoot, arch, and heel), thereby maximizing the removal of heat and moisture. In this way, together with the active exhaust system of the sole 200, it achieves a comprehensive and efficient dry and comfortable foot experience.

[0036] It should be noted that, in FIGS. 1 to 9, the supporting protrusions 234 are illustrated in the form of elongated ridges, but this does not mean that they are limited to such a shape. They may also appear as small square protrusions, as in the parent case, or as irregular protrusions, as shown in FIG. 10. The supporting insole 230 and the sole body 210 may be partially or entirely integrated as a single unit.

[0037] In this embodiment, the protrusion height of the supporting protrusions 234 is at least 1 mm, the distance between adjacent supporting protrusions 234 ranges from 1 mm to 15 mm, and a surface area of the upper surface of each supporting protrusion 234 is at least 2 mm.sup.2. The depth of the air guiding mesh network 231 is limited by the protrusion height of the supporting protrusions 234, while the groove width is limited by the spacing between the supporting protrusions 234.

[0038] During use, the depth of the air guiding mesh network 231 is determined by the protrusion height of the supporting protrusions 234, and the groove width is determined by the spacing between adjacent supporting protrusions 234. Such a design allows precise control of the shape and dimensions of the air guiding mesh network 231, thereby guiding airflow more effectively. Suitable depth and groove width reduce turbulence and resistance when airflow passes through the groove network, ensuring that the airflow follows the intended path and enabling efficient distribution and guidance of air.

[0039] A height of the supporting protrusions 234 of 1 mm to 4 mm provides moderate support to the foot. If the height is too low, the support effect is negligible and cannot effectively disperse foot pressure; if too high, excessive localized pressure may occur, causing discomfort. The specified range ensures comfort while providing adequate support. A distance of two adjacent supporting protrusions of 1 mm to 15 mm allows reasonable control of airflow volume. If the distance of two adjacent supporting protrusions is too narrow, increases airflow resistance, affecting heat dissipation; too wide, although increasing airflow, may result in uneven distribution. The minimum protrusion height of 1 mm ensures effective foot support, providing necessary cushioning and stability, while also defining a minimum depth (1 mm) of the air guiding mesh network 231, ensuring a basic space for airflow. Meanwhile, the spacing of 1 mm to 15 mm finely regulates the groove width of the air guiding mesh network 231. This range is designed to achieve a key balance: on the one hand, ensuring that the density of support points is sufficient to evenly disperse plantar pressure and avoid excessive local stress; on the other hand, ensuring that the groove width is sufficient to form an efficient and comprehensive airflow passage network.

[0040] The synergy of these dimensional parameters allows the air guiding mesh network 231 to more fully and evenly redistribute and guide the airflow drawn from the external environment, effectively penetrating the entire plantar region (including the forefoot, arch, heel, and other key areas), thereby maximizing the cooling and dehumidification effect. This works closely in cooperation with the active exhaust system of the sole 200 to achieve unified stable support and excellent ventilation for a dry and comfortable wearing experience. The surface area of the upper surface of each supporting protrusion 234 is at least 2 mm.sup.2 to avoid excessive localized pressure that could cause discomfort or a pressing sensation.

[0041] In this embodiment, the supporting insole 230 further includes a fitting surface 235. The insole surface 233 and the fitting surface 235 are disposed on opposite sides of the supporting insole 230, with the other end of the ventilation hole 232 communicating with the fitting surface 235. The airflow distributing device 220 is disposed beneath the fitting surface 235. Through this structural arrangement, during use, by defining the fitting surface 235 and its spatial relationship with key components, the integrity and efficiency of the airflow pathway are optimized. The fitting surface 235, being the side of the supporting insole 230 facing the sole body 210, on one hand provides a physical interface with the sole body 210 (especially with the airflow distributing device 220 located beneath it), ensuring structural stability; on the other hand, it serves as a key hub for airflow transmissionits end connected with the ventilation hole 232 directly receives the airflow introduced from above through the operation of the airflow distributing device 220. This arrangement minimizes resistance and leakage during the airflow transmission process, ensuring that the ventilation system for the sole receives a direct, sufficient, and well-controlled airflow source. Thus, in synergy with the active driving of the airflow distributing device 220 and the precise distribution of the air guiding mesh network 231, it achieves efficient and uniform foot dryness and comfort.

[0042] In this embodiment, the airflow distributing device 220 includes an air inlet 221 and an air outlet 222. The air inlet 221 is in communication with the wearing space 300 of the shoe, and the air outlet 222 is in communication with the exhaust port 211 on the bottom of the sole 200. Moist and hot air inside the shoe is drawn from the wearing space 300 through the air inlet 221, passes through the air outlet 222, and is finally discharged outside the shoe via the exhaust port 211. Through the above structural configuration, by constructing the communication relationship between the air inlet 221 and the air outlet 222, efficient directional extraction and discharge of moist and hot air is achieved. Specifically, the air inlet 221 is directly connected to the wearing space 300 of the shoe, serving as the active suction entry for moist and hot air. The air outlet 222 is connected to the exhaust port 211 on the bottom of the sole 200, serving as the final exit for the discharge of moist and hot air. This design constructs a closed and unidirectional forced airflow passage: moist and hot air inside the shoe (wearing space 300) is actively drawn out through the air inlet 221.fwdarw.flows through the interior of the airflow distributing device 220.fwdarw.guided via the air outlet 222 toward the exhaust port 211.fwdarw.and finally discharged into the external environment. In this way, on one hand, moist and hot air is precisely captured and removed from the source (wearing space 300); on the other hand, the explicit inlet-outlet design optimizes airflow directionality, reduces turbulence and energy loss, and improves exhaust efficiency. Furthermore, the direct communication between the air outlet 222 and the exhaust port 211 achieves the shortest path and most efficient discharge of moist and hot air to the outside of the shoe.

[0043] In this embodiment, the ventilation holes 232 are connected to the wearing space 300 through the airflow passage formed inside the air guiding mesh grooves 231, and the ventilation holes 232 are arranged near the air inlet 221. The supporting insole 230 is further provided with a mounting groove 236 and a diversion groove 237. The air inlet 221 is arranged opposite the opening of the mounting groove 236. The airflow passage formed inside the air guiding mesh grooves 231 communicates with the diversion groove 237, and the airflow passage formed inside the air guiding mesh grooves 231 communicates with the bottom of the diversion groove 237. The diversion groove 237 is in communication with the mounting groove 236.

[0044] Through the above configuration, during use, ventilation efficiency is improved by a refined airflow path design. Firstly, the ventilation holes 232 of the supporting insole 230 are positioned close to the air inlet 221 of the airflow distributing device 220, forming the shortest direct airflow connection and reducing energy loss. Secondly, the mounting groove 236 is set opposite the air inlet 221 to ensure low-loss airflow injection, while the diversion groove 237 serves as a hub to direct airflow downward from the three-dimensional network bottom of the air guiding mesh grooves 231 into the airflow distributing device 220, completing the conversion from planar diffusion to concentrated discharge. Thirdly, as the airflow is directed downward through the three-dimensional airflow passage formed in the air guiding mesh grooves 231, it is evenly distributed across the entire sole, thereby eliminating ventilation dead zones. This embodiment, through coordinated grooves and optimized pathways, realizes efficient and low-loss airflow transmission, significantly improving ventilation uniformity and heat dissipation performance at the sole.

[0045] In this embodiment, the airflow distributing device 220 includes a motor 223, a fan 224, a installation frame 225, and an installation cover 226. The installation frame 225 is detachably connected to the installation cover 226, and together they define an installation space 227. The motor 223 and/or the fan 224 can be detachably mounted inside the installation space 227. The air inlet 221 is arranged on the installation cover 226, and the air outlet 222 is arranged on the installation frame 225.

[0046] Through the above structural arrangement, the airflow distributing device 220, using a modular detachable structure (the installation frame 225 and installation cover 226 forming the installation space 227), integrates the active ventilation core components (the fan 224 driven by the motor 223), thereby achieving efficient and directional forced discharge of moist and hot air. The top (installation cover 226) is provided with the air inlet 221 directly connected to the wearing space 300 to extract moist and hot air, while the bottom (installation frame 225) is provided with the air outlet 222 connected to the exhaust port 211 on the sole bottom to guide airflow outside, forming a high-efficiency directional airflow passage. On one hand, provides active driving force to significantly accelerate air exchange between the inside and outside of the shoe; on the other hand, it optimizes the airflow pathway to ensure source capture of moist and hot air and its discharge along the shortest path. Meanwhile, the detachable structure greatly enhances maintainability (cleaning, component replacement), ensuring long-term reliable operation. In short, the airflow distributing device 220 is a core power unit integrating active ventilation, efficient air guiding, and convenient maintenance, fundamentally enhancing the dryness and comfort inside the shoe.

[0047] In this embodiment, the air outlet 222 is provided with a supporting mesh 228, which is embedded. The supporting mesh 228 is integrally formed. Through the above structure, in use, the integral formation eliminates seam weaknesses, significantly enhancing compression and deformation resistance, and adapting to frequent stepping impacts on the sole 200. The supporting mesh 228 is embedded in the air outlet 222, on one hand, effectively blocks external dust, debris, and other foreign matter from backflowing into the device interior via the exhaust port 211. thereby protecting precision components (such as the fan 224 and motor 223); on the other hand, the embedded supporting mesh 228 enhances the rigidity of the supporting mesh 228 itself and its joint strength with the air outlet 222, enabling it to withstand stepping impacts from the sole 200, preventing deformation or detachment, while maintaining smooth airflow to ensure efficient discharge of moist and hot air.

[0048] In this embodiment, the air outlet 222 is provided with a supporting column 229, which is arranged on a side of the air outlet 222 close to the fan 224. Through this configuration, when in use, a rigidity of the air outlet 222 region is enhanced, resisting stepping impacts on the sole 200, and maintaining the stability of the airflow passage 132.

[0049] In this embodiment, the fan 224 includes an upper surface 2241. The angle between a plane where the exhaust port 211 is located and an axis perpendicular to the upper surface 2241 of the fan is between 70 degrees and 110 degrees. Through this arrangement, when in use, the non-linear angular design can guide airflow to form a more complex flow path inside the shoe, extending the contact time between airflow and the foot, thereby more effectively carrying away heat, moisture, and odor, and improving breathability. At the same time, the spatial coordination between the air outlet 222 and the exhaust port 211 enables rational layout within a limited structure, avoiding internal passage crossing or interference, while simplifying mold forming difficulty and improving manufacturing feasibility.

[0050] In this embodiment, the bottom of the sole 200 is also provided with an exhaust passage 240, which is located around the exhaust port 211. The exhaust passage 240 is designed to guide the airflow discharged by the airflow distributing device 220 to flow through the exhaust passage 240 and be expelled outside the shoe. With this arrangement, during use, the exhaust passage 240 regulates the airflow path generated by the airflow distributing device 220, preventing chaotic flow and ensuring that the airflow is efficiently and centrally discharged outside the shoe. At the same time, it optimizes the airflow discharge path, reduces flow resistance, and enhances the breathability of the sole 200, helping to quickly expel warm, humid air from the wearing space 300 and maintain a dry environment inside the wearing space 300.

[0051] In this embodiment, the shoe upper 100 includes an outer layer 110, an inner layer 120, and a middle layer 130. The middle layer 130 is equipped with a flexible supporting structure 131 and forms an airflow passage 132. With this arrangement, during use, the three-layer structure of the upper creates a protective outer layermiddle layer for supporting and airflow guidancecomfortable inner layer layered design, establishing a mechanical support+air circulation dual-function system. The flexible supporting structure 131 addresses the issues of traditional uppers where rigid supports are impermeable, and soft materials provide no support. while the airflow passage 132 works in conjunction with the sole 200s ventilation system to create a three-dimensional breathable network across the entire shoe. This ultimately achieves a multidimensional balance of support, breathability, comfort, and durability, suitable for footwear products that require high functionality. It should be noted that the flexible supporting structure 131 is capable of forming the airflow passage 132 within the middle layer 130 of the upper, allowing air to pass through the middle layer 130 into the wearing space 300. Moreover, through this structure, it is possible to address the intake issue without creating obvious openings in the upper. A shoe upper hole 140 of traditional shoes, as illustrated in this embodiment, can also solve the intake problem, but it does not achieve the effect of having no obvious openings. The simultaneous illustration of the shoe upper hole 140 of traditional shoes 140 and the airflow passage 132 does not imply the need to include both structures; one or the other can be selected based on needs.

[0052] In this embodiment, the flexible supporting structure 131 is a flexible conduit or a sandwich mesh. During use, the flexible supporting structure 131 may be a flexible conduit, but the structure can also be entirely a sandwich mesh as long as it forms the airflow passage 132 in the middle layer 130 of the upper, allowing air to pass through the middle layer 130 into the wearing space 300.

[0053] In this embodiment, the shoe upper 100 is provided with a shoe upper hole 140, which communicates with the wearing space 300. As a passive intake channel for external fresh air, the shoe upper hole 140 in combination with the airflow distributing device 220, forms an efficient convective circulation, preventing the negative pressure in the wearing space 300 from obstructing ventilation when air is being extracted.

[0054] In this embodiment, the sole 200 is provided with a sole hole 260, which communicates with the wearing space 300. The sole hole 260 in cooperation with the upper opening 140 and the airflow passage 132, helps introduce external air, accelerating the removal of warm, humid air from the shoe by the airflow distributing device 220, forming an efficient circulation.

[0055] In this embodiment, the sole 200 also includes an airflow guiding slope 250, with an angle between the airflow guiding slope 250 and the bottom of the sole 200 being acute. During use, the acute angle design of the airflow guiding slope 250 optimizes the fluid flow path and enhances the exhaust efficiency. The acute angle design causes the bottom surface of the exhaust passage 240 to be inclined, which better suits the airflow's streamlined needs compared to a horizontal surface, reducing impact and vortex formation, thereby lowering energy loss and improving exhaust efficiency.

[0056] In this embodiment, the shoe also includes a power supply 400 and a control circuit board 500. The power supply 400 provides stable power to the active ventilation system, ensuring continuous operation, while the control circuit board 500 adjusts the ventilation intensity and mode dynamically according to preset logic (such as temperature and humidity sensing or scheduled start/stop) or user instructions, achieving a balance between energy efficiency and comfort.

[0057] In this embodiment, the power supply 400 is detachable. This allows users to replace the power supply 400 with a spare one at any time, eliminating the need to wait for charging and ensuring continuous operation of the ventilation system. If the power supply 400 reaches an end of its lifespan or malfunctions, it can also be directly replaced, avoiding the need to discard the entire shoe and reducing long-term usage costs. Furthermore, this feature makes it easier to recycle the power supply 400, avoiding the risks associated with dismantling and supporting technology iteration and upgrades.

[0058] In this embodiment, the power supply 400 supports wireless charging. This design frees the user from the constraints of plug-and-play connections, enabling charging by simply placing the shoe on a charging pad, greatly enhancing the charging experience. It also eliminates the need for physical charging ports, completely preventing the risk of sweat or dust infiltration and improving the overall waterproof and dustproof level of the shoe. Additionally, wireless charging avoids the wear and tear caused by repeated plugging and unplugging, reducing the failure rate.

[0059] In this embodiment, the airflow distributing device 220 is positioned in the middle of the sole body 210. Thus, ensuring a middle part of the sole body 210 closely aligns with the foot arch, an area rich in sweat glands, allowing it to directly capture the core source of warm, humid air, shortening the airflow path to maximize suction efficiency. The central placement also ensures that the airflow covers both the forefoot and heel simultaneously, enhancing overall ventilation uniformity.

[0060] An in-shoe temperature monitoring device, applied to the shoe, which is provided in the sole body 210, includes a temperature sensor 10. The temperature sensor 10 consists of a temperature sensing probe 11, which is suspended and has its surrounding space connected to the wearing space 300. The suspended design of the temperature sensing probe 11 (or at least partially suspended) connected to the wearing space 300 enables precise, real-time monitoring of the shoe's internal temperature. This provides reliable data support for the shoe's smart temperature control system (such as fan start/stop and speed adjustment), ensuring the microclimate inside the shoe remains in a comfortable range (e.g., 26-30 C.).
