Air conditioning shoe exhaust module, air conditioning shoe sole and air conditioning shoes

Abstract

This invention discloses an air-conditioning shoe exhaust module, comprising a shell made of elastic soft material, the shell being a hollow, arc-shaped thin sheet. One end edge of the shell has an air inlet for receiving gas from the shoe's breathing chamber. The arc-shaped convex surface of the shell has a first outward protrusion, the tip of which has an air outlet for exhausting gas into the shoe's external space. The end of the shell located at the air inlet is fixedly connected to the shoe sole, and the inner wall of the shell has a second protrusion supporting the hollow structure. After installation, this invention maintains consistency with the curved surface of the shoe sole, preventing the formation of a geometrically discontinuous blocky area on the sole. This allows the shell to bend and deform synchronously with the sole when the user walks, preventing localized stress concentration and eliminating the foreign body sensation and pressure feeling associated with existing exhaust valves on the user's feet.

Description

Technical Field

[0001] This invention relates to the field of shoe ventilation technology, and more particularly to an exhaust module for air-conditioned shoes, an air-conditioned shoe sole, and air-conditioned shoes. Background Technology

[0002] Shoes are an everyday necessity, and air-conditioned shoes are a new type of footwear that has emerged in recent years. They lower the temperature and expel moisture by ventilating the inside of the shoe, thus keeping the feet dry.

[0003] Existing air-conditioned shoes typically achieve breathability and sweat-wicking by incorporating a compressible breathing chamber in the sole and a dedicated one-way valve. This allows for gas exchange between the inside and outside of the shoe through foot movements such as stepping and bending during walking. For example, Chinese invention patent CN115886395B discloses an actively closing one-way valve, a ventilation mechanism, a breathable insole, and a sole.

[0004] However, to support the structural stability of the exhaust channel, the valve body of this type of one-way valve needs to adopt a rigid or semi-rigid cylindrical or square hollow structure and be embedded in the sole. This creates a geometrically discontinuous hard area in the sole, causing an abrupt change in the overall softness and elasticity of the sole at the exhaust valve installation point, resulting in varying degrees of foreign body sensation and pressure when walking. Furthermore, when the sole bends and deforms, the rigid valve body cannot bend synchronously, leading to localized stress concentration and severely limiting the expansion of air-conditioned shoes into sports scenarios.

[0005] Although some manufacturers use soft materials to make one-way valves to improve the comfort of sports, the structural problem still disrupts the material continuity of the sole due to the fundamental difference in shape between the cylindrical or square block shell and the curved surface of the sole. Therefore, it cannot completely eliminate the obstruction to the deformation of the shoe as the foot moves, which is especially obvious in sports scenarios.

[0006] Therefore, in order to improve the market prospects of air-conditioned shoes in sports scenarios, this application proposes an air-conditioned shoe exhaust module, air-conditioned shoe sole, and air-conditioned shoes that can maintain the continuity of the sole material, can bend and deform completely synchronously with the sole, and do not generate local stress concentration, and are suitable for various sports scenarios. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and propose an air-conditioning shoe exhaust module, an air-conditioning shoe sole, and an air-conditioning shoe. After installation, the exhaust module can maintain the same shape as the curved surface of the shoe sole and will not form a geometrically discontinuous blocky area on the shoe sole. This allows the outer shell to bend and deform synchronously with the shoe sole when the user walks, without generating local stress concentration, and eliminating the foreign body sensation and top-touching sensation of the user's feet caused by the existing exhaust valve.

[0008] Firstly, in order to achieve the above objectives, the present invention provides the following technical solution: An air-conditioning shoe exhaust module includes a shell made of elastic soft material, the shell being a hollow sheet, an air inlet for receiving gas from the shoe sole breathing chamber on one side edge of the shell, and an air outlet for exhausting gas into the outside space of the shoe on one side or end of the shell. The outer shell is located at one end of the air inlet for fixed connection with the sole of the shoe, and the inner wall of the outer shell is provided with a second protrusion to support the hollow structure.

[0009] Using this method, the outer shell can maintain the same shape as the curved surface of the shoe sole after installation, and will not form a geometrically discontinuous blocky area on the sole. This allows the outer shell to bend and deform synchronously with the sole when the user walks, without generating local stress concentration, and eliminating the foreign body sensation and top-touching sensation of the existing exhaust valve on the user's feet.

[0010] In conjunction with the first aspect, in one embodiment, the soft elastic material is at least one of silicone, thermoplastic polyurethane elastomer, thermoplastic polyester elastomer, or rubber.

[0011] This approach provides a variety of feasible and mature material options for the exhaust module without compromising the core functions of eliminating foreign body sensation and conforming to shoe deformation provided by the curved sheet structure of the outer shell. Manufacturers can flexibly choose the appropriate option based on actual product positioning and cost control requirements.

[0012] In conjunction with the first aspect, in one embodiment, the bottom end of the outer shell conforms to the arcuate contour of the sole, and the surface of the outer shell conforms to the curved contour of the shoe body and is fixedly connected to the shoe body.

[0013] This implementation method not only makes the installation of the exhaust module more stable, but also, as the outer shell serves as a transitional curved surface connecting the sole and the upper, it further eliminates the sense of boundary formed at the junction of the sole and upper in traditional exhaust valves, improving the overall comfort of wearing the shoe and making it better able to adapt to shoe deformation during user walking and exercise.

[0014] In conjunction with the first aspect, in one embodiment, the surface of the housing is wider at the end near the air inlet than at the opposite end.

[0015] Using this method, a shell with a shape that precisely matches the curved surface of the shoe is constructed. After installation, the edge of the shell transitions naturally with the sole and the edge of the shoe body, without any local lifting or gaps. It is more conducive to becoming part of the original shoe body, with better deformation and fit performance, and truly achieves zero restraint on the user's feet when walking.

[0016] In conjunction with the first aspect, in one embodiment, the outer shell is in the form of a hollow, arc-shaped sheet, and the air outlet is located on the arc-shaped convex surface of the outer shell. The shape of the air outlet includes at least one of the following: straight, wavy, annular, semi-annular, cross-shaped, and Y-shaped.

[0017] This implementation provides a variety of exhaust port structure schemes with different performance characteristics, allowing for flexible selection of different tip shapes to adjust the exhaust efficiency, self-sealing performance, and appearance of the exhaust port.

[0018] In conjunction with the first aspect, in one embodiment, the first protrusion includes at least two nested protrusions, each of which is interconnected and has its tip pointing outwards from the shoe body.

[0019] By adopting this implementation method, multiple mutually redundant airflow output paths are constructed for the exhaust module through the nested structure of the protrusions, which significantly improves the functional stability of the product in harsh environments such as rain, mud, and dust, allowing users to obtain a reliable ventilation experience under various outdoor conditions.

[0020] In conjunction with the first aspect, in one embodiment, the tip angle of the first protrusion is 15° to 75°.

[0021] This implementation provides a ventilation structure design that can meet the requirements of different shoe models, different ventilation sensitivities, and different waterproof ratings.

[0022] In conjunction with the first aspect, in one embodiment, the arc-shaped convex surface of the outer shell is provided with a first protrusion protruding outward, and the air outlet is located at the tip of the first protrusion; the outer shell includes an inner layer and an outer layer, both of which are arc-shaped thin sheets, the first protrusion is located on the arc-shaped convex surface of the outer layer, and the second protrusion is located on the outer convex surface of the inner layer and / or the inner concave surface of the outer layer.

[0023] The implementation method uses an inner and outer layer stacked structure, which makes the processing and manufacturing of the outer shell very simple. Furthermore, the first protrusion and the second protrusion are formed in one piece with the outer shell body, eliminating the need for subsequent assembly. This ensures structural consistency and reduces production costs, which is beneficial for meeting the supply needs of high-frequency consumer markets such as footwear.

[0024] In conjunction with the first aspect, in one embodiment, the shape of the first protrusion includes at least one of wedge, cone, and sphere; the shape of the second protrusion includes at least one of linear and dotted.

[0025] This approach enriches the design options for the second protrusion, allowing users to choose a more suitable exhaust channel design based on the product's actual comfort and exhaust efficiency requirements.

[0026] In conjunction with the first aspect, in one embodiment, the second protrusion is strip-shaped, the bottom end of the second protrusion is not lower than the bottommost end of the outer casing, and the top end of the second protrusion extends into the root region of the first protrusion.

[0027] By adopting this implementation method, the strip-shaped protrusion provides a longitudinal support for the air passage, completely eliminating the possibility of air passage interruption due to local pressure, and significantly improving the functional reliability of the exhaust module throughout the entire gait cycle.

[0028] In conjunction with the first aspect, in one embodiment, the housing protrudes from the end face of the housing at the end of the air inlet.

[0029] With this implementation, the protruding air inlet end fits into the slot on the sole like a plug, greatly simplifying the alignment and pre-fixing process during assembly. This is more conducive to product consistency during standardized production. At the same time, it increases the connection area between the outer shell and the sole, which helps to improve the airtightness and mechanical strength at the interface between the outer shell and the sole.

[0030] Secondly, in order to achieve the above objectives, the present invention also provides the following technical solution: An air-conditioned shoe sole includes a lower sole, an upper sole, and a first-sided exhaust module. The lower sole and the upper sole are sealed together at the edges to form a breathing chamber. An elastic support body is also provided inside the breathing chamber. An air inlet hole penetrating the breathing chamber is provided on the top surface of the upper sole and at the forefoot. An air passage for connecting the outer shell mounting location is provided in the elastic support body and / or the elastic support body is made of an elastic porous material. The outer shell is sealed together with the edge of the shoe sole.

[0031] By adopting this implementation method, the arc-shaped thin-film exhaust module is completely integrated into the sole structure, forming a complete air path from air intake, temporary storage, diversion to exhaust. Moreover, the exhaust module itself is not embedded inside the sole, so it does not affect the uniformity and softness of the sole material, thus preventing users from experiencing a "foreign object" sensation while walking and not affecting their walking ability.

[0032] In conjunction with the second aspect, in one embodiment, the heel edge of the upper sole is provided with a notch, and the end of the outer shell located at the second protrusion is inserted into the notch and sealed to the edge of the notch.

[0033] By adopting this implementation method, the notch-type insertion positioning method reduces assembly difficulty, improves production efficiency, and also ensures the sealing reliability of the interface.

[0034] Thirdly, in order to achieve the above objectives, the present invention also provides the following technical solution: Air-conditioned shoes, including an air-conditioned sole in the second aspect, and a shoe body fixedly connected to the top edge of the sole, wherein the concave surface, convex surface and / or side edge of the outer shell are fixedly connected to the shoe body.

[0035] By adopting this implementation method, the fixation of the shoe body to the concave surface of the outer shell and the fixation of the bottom to the bottom of the outer shell form a dual constraint, which enables the exhaust module to work stably even during vigorous exercise, while also taking into account the overall appearance of the shoe.

[0036] Fourthly, in order to achieve the above objectives, the present invention also provides the following technical solutions: The manufacturing method of air-conditioned shoes includes: The shell is integrally formed into a hollow, arc-shaped sheet using injection molding, blow molding, or 3D printing processes, and the second protrusion is formed on the inner wall of the shell. The concave surface of the outer shell is placed at the outer edge of the formed upper bottom and sealed together. The elastic support body is sandwiched between the lower and upper soles and then injection molded to seal the edges, thus obtaining the air-conditioning shoe sole; Assemble the shoe body onto the sole of the air-conditioned shoe to obtain the air-conditioned shoe.

[0037] Using this method, the molding of the outer shell and the final sealing of the sole are independent yet closely connected, with a clear process route, suitable for standardized production, and able to ensure the airtightness of the connection between the breathing chamber and the outer shell.

[0038] In conjunction with the fourth aspect, in one embodiment, the injection-molded housing includes: Two soft, elastic material arc-shaped sheets are integrally molded using injection molding, namely an inner layer and an outer layer. The outer layer has a concave surface with a first wedge-shaped protrusion on the arc-shaped convex surface. The lower part of the outer convex surface of the inner layer or the lower part of the inner concave surface of the outer layer has a linear or dot-shaped second protrusion. The inner and outer layers, except for the lower edge, are sealed to form an outer shell.

[0039] Using this method, the inner and outer layers of the shell with all functional structures can be obtained through a single injection molding process. The shell manufacturing can be completed by a simple edge sealing process. It has high production efficiency, good product consistency, and is particularly suitable for mass production.

[0040] Compared with the prior art, the beneficial effects of this invention are as follows: after installation, this exhaust module can keep in line with the curved shape of the shoe sole, and will not form a geometrically discontinuous blocky area on the shoe sole. This allows the outer shell to bend and deform synchronously with the shoe sole when the user walks, without generating local stress concentration, and eliminating the foreign body sensation and top-touching sensation of the existing exhaust valve on the user's feet.

[0043] To achieve its ventilation function, existing air-conditioned shoes typically incorporate a dedicated one-way valve on the sole. However, to support the structural stability of the ventilation channel, this valve body is usually a cylindrical or square hollow structure, embedded in the sole. This creates a geometrically discontinuous, rigid area on the sole, causing a sudden change in the overall softness and elasticity of the sole at the valve installation point. This results in a persistent feeling of foreign objects and pressure on the surface when walking. Furthermore, when the sole bends and deforms, the rigid valve body cannot bend synchronously, severely limiting the expansion of air-conditioned shoes into various sports scenarios.

[0044] Although some manufacturers use soft materials to make one-way valves to improve the comfort of sports, the structural problem still disrupts the material continuity of the sole due to the fundamental difference in shape between the cylindrical or square block shell and the curved surface of the sole. Therefore, it cannot completely eliminate the obstruction to the deformation of the shoe as the foot moves, which is especially obvious in sports scenarios.

[0045] It should be understood that the following embodiments are all intended to address the problem that the installation of existing ventilation structures can affect the material properties of the sole itself, thus limiting the application of air-conditioned shoes in sports scenarios.

[0046] The soft, elastic materials mentioned should be considered as materials that are soft and elastic, such as plastics and rubber.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1: Please see Figure 1-6 and Figure 8-9 The present invention provides the following technical solution: an exhaust module for air-conditioned shoes, including a shell 1 made of elastic soft material, the shell 1 being a hollow arc-shaped thin sheet, an air inlet 13 for receiving gas from the shoe sole breathing chamber 4 on one side edge of the shell 1, and an air outlet 1211 for exhausting gas into the shoe space on the arc-shaped convex surface of the shell 1. The outer shell 1 is located at one end of the air inlet 13 for fixed connection with the sole of the shoe, and the inner wall of the outer shell 1 is provided with a second protrusion 123 to support the hollow structure. As an optional implementation of the present invention, during assembly, the end of the outer shell 1 located at the air inlet 13 is fixedly connected to the outline edge of the sole by means of bonding, plastic sealing or other methods, so that the air inlet 13 is connected to the breathing chamber 4 of the sole. When the shoe body 6 is installed, the surface of the outer shell 1 is fixed to the surface of the shoe body 6 by means of sewing, bonding or other methods, thereby obtaining a complete air-conditioned shoe.

[0049] When a user wears the assembled air-conditioned shoes and walks, the breathing chamber 4 in the sole exhausts air into the air inlet 13 due to the user's footsteps. The airflow enters the outer shell 1 through the air inlet 13, forming high pressure. The outer shell 1, made of elastic soft material, can automatically open the air outlet 1211 when subjected to internal air pressure. The gas inside the outer shell 1 is then discharged to the external environment through the air outlet 1211, realizing the exhaust function of the air-conditioned shoes. When the internal pressure of the outer shell 1 is balanced with the external atmospheric pressure, the air outlet 1211 automatically closes due to the elastic reaction force of its own material, preventing external rainwater, dust, and impurities from entering the outer shell 1 through the air outlet 1211.

[0050] As users walk, the direction of force on the shoe body 6 and sole changes. The common sole, which is elastic, can deform in response to the force, thereby cushioning the force on the user's foot. At this time, since the outer shell 1 is a curved thin sheet with a certain curvature, its curvature can match the perimeter of the sole and / or the curved surface of the shoe body 6. Therefore, it can fit the edge of the sole and / or the surface of the shoe body 6, and thus cooperate with the deformation of the user's foot and the shoe body 6. It bends and twists synchronously with the deformation of the sole and the shoe body 6, and will not form a rigid node that hinders deformation at any point.

[0051] Compared to existing cylindrical or square valve bodies, the outer shell 1 can fit snugly against the outer curved surface of the sole or the surface of the shoe body 6 during installation and communicates with the inner liner breathing chamber 4 of the sole. Unlike existing exhaust valves, it does not need to be embedded in corresponding holes inside the sole, thus not occupying space in the sole material and preventing the sole from forming a discontinuous or uneven structure. Therefore, it does not affect the structural characteristics of the sole itself. Furthermore, since the outer shell 1 is made of elastic soft materials such as silicone and TPU, when the user wears it and walks, the pressure from the foot smoothly transitions from the center to the edge of the outer shell 1. The outer shell 1 bends and deforms synchronously with the sole, without generating localized stress concentration. Therefore, the user does not perceive the distinct boundary and tactile sensation of traditional blocky exhaust valves, achieving the goal of eliminating the foreign object sensation at the structural level.

[0052] The second protrusion 123 on the inner wall of the outer shell 1 is raised inside the hollow interior of the outer shell 1. When the outer shell 1 is subjected to external pressure (such as being flattened by a foot stepping on it), the second protrusion 123 can press against the inner wall on the opposite side, preventing the inner and outer walls from completely adhering and causing air passage blockage, thus ensuring unobstructed airflow. However, since the second protrusion 123 is also located outside the sole, it does not affect the structural characteristics of the sole itself. Its own elastic and soft material properties can also deform in accordance with the deformation of the shoe body 6, thus ensuring unobstructed airflow while also ensuring that the user does not feel any foreign objects when walking.

[0053] It should be understood that the term "arc-shaped" in this sheet-like exhaust module refers to its overall curved or spherical sheet-like structure. More specifically, it refers to the arc shape from the side view, rather than the fact that the edges of the entire sheet are limited to an arc shape from the front view. In fact, from the front view, this exhaust module can be any shape such as circular, rectangular, or polygonal, and this embodiment does not limit it in this way.

[0054] In this embodiment, the specific connection position of the outer shell 1 on the sole can be the heel, the toe, or other parts, depending on the functional classification of the shoe (such as leather shoes, rain boots, sports shoes, etc.). Of course, the heel is generally preferred, but those skilled in the art can choose different sizes of outer shell 1 to assemble the air-conditioned shoe according to actual needs. It should be understood that any method of installing the outer shell 1 at the edge of the sole outline in this embodiment is within the scope of this embodiment. Regarding the specific connection method of the outer shell 1 on the sole, considering that air-conditioned shoes cannot do without sealing, a suitable sealing and fixing method can be selected, such as bonding, one-piece molding, injection molding, plastic sealing, etc. This embodiment does not make specific limitations in this regard.

[0055] In some other embodiments, the air outlet 1211 may also be located at the end of the housing 1, i.e., as shown below. Figure 10 The top of the outer shell 1 shown should also be included in the scope of this embodiment.

[0056] Using this implementation method, the outer shell 1 can maintain the same shape as the curved surface of the shoe sole after installation, and will not form a geometrically discontinuous block area on the shoe sole. This allows the outer shell 1 to bend and deform synchronously with the shoe sole when the user walks, without generating local stress concentration, and eliminating the foreign body sensation and top-touching sensation of the existing exhaust valve on the user's feet.

[0057] In some possible embodiments, the shape of the air outlet 1211 includes at least one of the following: straight, wavy, annular, semi-annular, cross-shaped, and Y-shaped. This embodiment does not limit this.

[0058] In some other embodiments, the outer shell 1 may also be a hollow, straight, thin sheet. Although this is somewhat contrary to ergonomics, it will not significantly obstruct the user's feet when the width is small, and therefore it is also somewhat usable. This embodiment does not limit this.

[0059] Example 2: Please see Figure 1-6 and Figure 8The present invention provides the following technical solution: an air-conditioning shoe exhaust module, including a shell 1 made of elastic soft material, the shell 1 being a hollow arc-shaped thin sheet, an air inlet 13 for receiving gas from the shoe sole breathing chamber 4 on one side edge of the shell 1, a wedge-shaped first protrusion 121 on the arc-shaped convex surface of the shell 1, and an air outlet 1211 for exhausting gas into the shoe space at the tip of the first protrusion 121. The outer shell 1 is located at one end of the air inlet 13 for fixed connection with the sole of the shoe, and the inner wall of the outer shell 1 is provided with a second protrusion 123 to support the hollow structure.

[0060] As an optional implementation of the present invention, during assembly, the end of the outer shell 1 located at the air inlet 13 is fixedly connected to the outline edge of the sole by means of bonding, plastic sealing or other methods, so that the air inlet 13 is connected to the breathing chamber 4 of the sole. When the shoe body 6 is installed, the surface of the outer shell 1 is fixed to the surface of the shoe body 6 by means of sewing, bonding or other methods, thereby obtaining a complete air-conditioned shoe.

[0061] When a user wears the assembled air-conditioned shoes and walks, the breathing chamber 4 on the sole exhausts air into the air inlet 13 due to the user's footsteps. The airflow enters the outer shell 1 through the air inlet 13, forming high pressure. The first protrusion 121, made of elastic soft material, can automatically open its tip air outlet 1211 when subjected to internal air pressure. The gas inside the outer shell 1 is then discharged from the air outlet 1211 of the first protrusion 121 to the external environment of the shoe, realizing the exhaust function of the air-conditioned shoes. When the internal pressure of the outer shell 1 is balanced with the external atmospheric pressure, the first protrusion 121 automatically closes the air outlet 1211 due to the elastic reaction force of its own material, preventing external rainwater, dust, and impurities from entering the outer shell 1 through the air outlet 1211.

[0062] Compared to existing one-way valves that use springs and spring plates, the first protrusion 121 in this design is a wedge-shaped structure, which can achieve a normally closed function by relying on the elasticity of the material itself. At the same time, this design does not require a large driving air pressure to push the spring and spring plate to open the valve. Therefore, the cushioning, shock absorption and exhaust response are more timely, with a significant reduction in delay, and users will not feel a foreign object sensation of "hard first and then soft" during walking. Especially when applied to high-end sports shoes, it is more adaptable to the user's high-frequency walking or running movements, and can significantly reduce the impact on the user's exercise.

[0063] As an optional implementation of the present invention, the first protrusion 121 can also be a cone or sphere protruding outwards. They have the same fluid dynamics principle as the wedge. When the external atmospheric pressure is greater than the internal atmospheric pressure, the pressure on the air outlet 1211 will further block the air outlet 1211. Therefore, it has the function of preventing external rainwater, dust and impurities from entering the outer shell 1 in reverse through the air outlet 1211.

[0064] Using this implementation method, the outer shell 1 can maintain the same shape as the curved surface of the shoe sole after installation, and will not form a geometrically discontinuous block area on the shoe sole. This allows the outer shell 1 to bend and deform synchronously with the shoe sole when the user walks, without generating local stress concentration, and eliminating the foreign body sensation and top-touching sensation of the existing exhaust valve on the user's feet.

[0065] In some possible embodiments, the soft elastic material is at least one of silicone, thermoplastic polyurethane elastomer, thermoplastic polyester elastomer, or rubber.

[0066] As an optional implementation of the present invention, silicone, thermoplastic polyurethane elastomer, thermoplastic polyester elastomer or rubber all have good elasticity and structural stability, which can meet the long-term use requirements of following the deformation of the shoe sole, and are easy to be integrally molded by injection molding, 3D printing and other processes, which can be adapted to the processing requirements of this exhaust module.

[0067] Of course, those skilled in the art can select one or more combinations of the above materials when manufacturing the outer shell 1, depending on the actual positioning and usage scenario of the shoe. For example, silicone material is soft and skin-friendly, making it suitable for daily commuting shoes or business leather shoes that require high comfort; thermoplastic polyurethane elastomer (TPU) has good abrasion resistance and tear resistance, making it suitable for sports shoes or outdoor shoes that require high frequency and high intensity use; thermoplastic polyester elastomer (TPE) has good processing flow properties and relatively low material cost, making it suitable for mass-produced products targeting the mass consumer market; rubber achieves a good balance between elasticity and material cost, making it suitable as a general-purpose option that allows for flexible material selection based on different price points and performance requirements.

[0068] This approach provides a variety of feasible and mature material options for the exhaust module without affecting the core functions of eliminating foreign body sensation and conforming to shoe deformation brought about by the arc-shaped thin sheet structure of the outer shell 1. Manufacturers can flexibly choose according to actual product positioning and cost control needs.

[0069] In some possible embodiments, such as Figure 2-3 and Figure 8 As shown, the bottom end of the outer shell 1, that is, the end of the outer shell 1 located at the air inlet 13, conforms to the arc-shaped contour of the sole, and the surface of the outer shell 1 conforms to the curved contour of the shoe body 6 and is fixedly connected to the shoe body 6.

[0070] As an optional implementation of the present invention, after the outer shell 1 is installed, the surface of the outer shell 1 (which can be a concave surface or a convex surface, depending on the specific installation position and method) fits the curved contour of the shoe body 6, making it easy to achieve multi-point fixation of the outer shell 1 between the sole and the shoe body 6. After installation, it is more secure, less likely to fall off, and can be used for a long time. At the same time, it is easier to follow the overall deformation of the shoe, without restricting the user's walking movements, allowing the user to truly experience the air-conditioned shoe without feeling it.

[0071] Of course, in some other embodiments, the two sides of the outer shell 1 can also be directly sewn or sealed to the shoe body 6, so that the outer shell 1 is directly part of the shoe body 6. For example, the middle layer, inner layer or outer layer of the shoe upper is made of the same material as the outer shell 1 (of course, the first protrusion 121 needs to be exposed on the outer surface of the shoe body 6 in the end), which can also be implemented.

[0072] This implementation method not only makes the installation of the exhaust module more stable, but also, as the transition surface connecting the sole and the upper 6, the outer shell 1 further eliminates the sense of boundary formed at the junction of the sole and the upper 6 of the traditional exhaust valve, improves the overall comfort of wearing, and has a better ability to adapt to the deformation of the shoe when the user walks.

[0073] In some possible embodiments, such as Figure 4 As shown, the surface of the outer casing 1 is wider at the end near the air inlet 13 (i.e., the bottom end) than at the opposite end.

[0074] As an optional implementation of the present invention, since most shoes on the market have a harder sole than the upper 6 to resist direct impact from the ground, the sole generally requires less deformation along the tangential direction of the sole profile compared to the upper 6. This is especially true for high-end sports shoes, particularly the heel area, which has a distinctly tapering curve from the foot to the calf. Therefore, this "wider at the bottom and narrower at the top" design is more in line with the sports design concept of the shoe and is more suitable to be directly integrated into the overall shoe design.

[0075] In addition, for the installation method that directly splices it into part of the shoe body 6, since most shoe bodies 6 are made of fabric that is wider at the bottom and narrower at the top, this design of the outer shell 1 that is wider at the bottom and narrower at the top is also quite suitable for this method.

[0076] Using this implementation method, a shell 1 with a shape that precisely matches the curved surface of the shoe body 6 is constructed. After installation, the edge of the shell 1 transitions naturally with the sole and the edge of the shoe body 6, without any local lifting or gaps. It is more conducive to becoming part of the original shoe body 6, with better deformation and fit performance, and truly achieves zero restraint on the user's feet when walking.

[0077] In some possible embodiments, the shape of the first protrusion 121 includes at least one of the following: straight, wavy, annular, semi-annular, cross-shaped, and Y-shaped.

[0078] As an optional implementation of the present invention, the first protrusion 121 with a straight tip is the most basic form. The air outlet 1211 extends in a straight line along the tip of the first protrusion 121, which has the simplest structure, is convenient for mold manufacturing and demolding, and is suitable for most general shoe models. Of course, the length of the straight air outlet 1211 can be adjusted by those skilled in the art according to the air exhaust volume requirements of the shoe model. For example, a shorter air outlet 1211 can be set for everyday casual shoes, while a longer air outlet 1211 can be set for professional running shoes to increase the exhaust area and improve exhaust efficiency.

[0079] As an alternative implementation of the present invention, the tip of the first protrusion 121 can also be wavy, in which case the air outlet 1211 extends along the wavy path. Compared with the straight air outlet 1211, the wavy air outlet 1211 not only directly increases the exhaust flow rate, but also helps to reduce the noise felt by the user, making it suitable for high-end sports scenarios such as sports competitions; in addition, it also helps to improve the structural strength, requiring more atmospheric pressure for the originally soft material to open the air outlet 1211, thus enhancing the ability to block the backflow of external fluids and impurities, making it suitable for complex outdoor weather and road conditions.

[0080] As an alternative implementation of the present invention, the tip of the first protrusion 121 is annular or semi-annular in shape, meaning the air outlet 1211 extends along a closed or semi-closed annular or semi-annular path. The advantage of an annular tip is that gas can be discharged simultaneously from multiple directions, without being limited by the shoe's orientation or tilt angle. Simultaneously, when subjected to external pressure, the stress in each direction can be evenly distributed in the annular gap, resulting in superior self-sealing performance.

[0081] This implementation provides a variety of exhaust port structure schemes with different performance, allowing for flexible selection of different tip shapes to adjust the exhaust efficiency, self-sealing performance, and appearance of the exhaust port 1211.

[0082] In other possible embodiments, such as Figure 7 As shown, the first protrusion 121 includes at least two nested protrusions 1212, each protrusion 1212 being interconnected and having its tip pointing outwards from the shoe body 6.

[0083] As an optional implementation of the present invention, specifically, a first protrusion 121 is formed by overlapping two or more layers of protrusions 1212, the shape of which can be wedge-shaped, conical, or spherical; this embodiment is not limited in this respect. The outer layer 12 protrusions 1212 are relatively large and hollow inside, with the inner layer 11 protrusions 1212 housed within this hollow area. The two layers are interconnected at the base, allowing airflow to flow smoothly from the inside to the outside of the shoe, and each protrusion 1212 has an independent air outlet 1211. This constitutes a set of multiple redundant exhaust channels. In actual walking, if the outer layer 12 air outlet 1211 is temporarily blocked by external mud, sand, or sewage, the gas can still be discharged normally through the inner layer 11 air outlet 1211, ensuring the effectiveness of the exhaust function.

[0084] By adopting this implementation method, the nested structure of the protrusion 1212 creates multiple mutually redundant airflow output paths for the exhaust module, which significantly improves the functional stability of the product in harsh environments such as rain, mud, and dust, allowing users to obtain a reliable ventilation experience under various outdoor conditions.

[0085] In some possible embodiments, such as Figure 5 As shown, the protrusion 1212 is preferably wedge-shaped, and the tip angle of the first protrusion 121 is 15° to 75°.

[0086] As an optional implementation of the present invention, the tip angle refers to the included angle between the two inclined surfaces of the wedge-shaped or V-shaped protrusion. The selection of this angle is directly related to the sealing force when the air outlet 1211 is closed and the amount of air pressure required when it is opened.

[0087] When the angle is smaller, the slopes on both sides are relatively steep, and the elastic force of the material itself is highly concentrated at the tip, making the vent 1211 close very tightly. Even with high external water pressure, it is not easy for water to backflow. However, correspondingly, the air pressure inside the shoe needs to accumulate to a higher level to open the gap, and the exhaust response will be slightly delayed. When the angle is larger, the slopes on both sides are gentle, and the material's elastic force is dispersed. The vent 1211 is easily opened by the internal airflow, and the exhaust resistance is minimal. However, the ability to resist backflow when facing external water flow is relatively weakened.

[0088] Therefore, within the range of 15° to 75°, both effective ventilation and basic reverse sealing can be achieved. For most footwear, to achieve an ideal balance between smooth ventilation and backflow prevention, those skilled in the art can prioritize setting the angle between 30° and 60°. For example, shoes emphasizing daily commuting and water repellency can use a tip angle of around 40°, while professional racing shoes pursuing ultimate ventilation efficiency can use an angle of 60° or even greater.

[0089] This implementation provides a ventilation structure design that can meet the requirements of different shoe models, different ventilation sensitivities, and different waterproof ratings.

[0090] In some possible embodiments, such as Figure 6 As shown, the outer shell 1 includes an inner layer 11 and an outer layer 12, both of which are arc-shaped thin sheets. A first protrusion 121 is provided on the arc-shaped convex surface of the outer layer 12, and a second protrusion 123 is provided on the convex surface of the inner layer 11 and / or the concave surface of the outer layer 12.

[0091] As an optional implementation of the present invention, since the outer shell 1 is a hollow structure and the air inlet and outlet directions are not parallel, it would be difficult to manufacture, or rather, difficult to mass-produce, if it were made in one piece, which would be unfavorable for the production of consumer products such as footwear. Therefore, from the perspective of ease of manufacturing, we divide the outer shell 1 into two layers, which are formed by stacking two curved thin sheets together.

[0092] The inner layer 11 is located near the inside of the shoe, while the outer layer 12 faces the outside of the shoe. The gap between the two layers forms a flat air passage 51 for gas flow. A wedge-shaped first protrusion 121 is integrally formed on the arc-shaped convex surface of the outer layer 12, ensuring that it fits the shape design of the shoe body 6 and can accurately release the gas inside the shoe into the outside space. The second protrusion 123, which supports the space of the air passage 51, can be flexibly set on the convex surface of the inner layer 11 (i.e., the side facing the outer layer 12), or on the concave surface of the outer layer 12 (i.e., the side facing the inner layer 11), or even simultaneously on the opposite surfaces of the inner and outer layers 12, depending on the mold design and process habits. For example, during injection molding, linear protrusions extending in the direction of airflow can be directly formed on the convex surface of the inner layer 11. When the inner layer 11 and the outer layer 12 are overlapped and sealed, these linear protrusions press against the concave surface of the outer layer 12, forming a supporting rib to prevent the air passage from closing.

[0093] In some embodiments, this overlapping outer shell 1 structure can be formed by folding a single piece of material in half, or by forming two pieces independently and then sealing the edges together, making the manufacturing process flexible.

[0094] Using this implementation method, the overlapping structure of the inner and outer layers 12 makes the processing and manufacturing of the outer shell 1 very simple. Furthermore, the first protrusion 121 and the second protrusion 123 are formed with the body of the outer shell 1 in one step, without the need for subsequent assembly. This not only ensures the consistency of the structure but also reduces production costs, which is conducive to meeting the supply demand of high-frequency consumer markets such as footwear.

[0095] In some possible embodiments, such as Figure 6 As shown, the shape of the second protrusion 123 includes at least one of linear and dotted shapes.

[0096] As an optional implementation of the present invention, the shape of the second protrusion 123 can be selected according to the specific needs of the shoe style. When the second protrusion 123 is linear, it usually extends along the airflow direction from the air inlet 13 to the air outlet 1211, forming one or more continuous guide ribs. These guide ribs not only support the inner and outer layers 12 when the outer shell 1 is stepped on, keeping the air passage 51 unobstructed, but also guide the airflow along a predetermined route, reducing the disordered turbulence of gas in the flat cavity, making exhaust smoother and quieter, and more suitable for shoes that pursue exhaust efficiency.

[0097] In other possible embodiments, the second protrusion 123 is dot-shaped, consisting of a large array of dispersed tiny protrusions. These protrusions are evenly or unevenly distributed on the inner wall of the outer shell 1. The dot-shaped protrusions can also press against the inner wall of the outer shell 1 when it is under pressure, and the gaps between the protrusions form a mesh channel for gas flow, ensuring that there are sufficient airflow gaps inside the outer shell 1. In addition, the dot-shaped protrusions are simpler to mold, and since there are no continuous ribs to centrally restrict the deformation direction of the outer shell 1, the outer shell 1 can deform more freely with the shoe body 6 when subjected to multi-angle extrusion forces, and the risk of local stress concentration is also lower, making it more suitable for product lines with higher requirements for comfort and cost control.

[0098] This approach enriches the design options for the second protrusion 123, allowing users to choose a more suitable exhaust channel design based on the product's actual comfort and exhaust efficiency requirements.

[0099] Preferred, such as Figure 6 As shown, the second protrusion 123 is strip-shaped, the bottom end of the second protrusion 123 is not lower than the bottom end of the outer shell 1, and the top end of the second protrusion 123 extends to the root area of ​​the first protrusion 121.

[0100] As an optional implementation of the present invention, as described above, the strip-shaped second protrusion 123 extends upwards from near the bottom of the outer shell 1 to below the root of the first protrusion 121, essentially creating a continuous "anti-collapse beam" within the flat air passage 51. The bottom of the outer shell 1, near the air inlet 13, is the part that first experiences pressure and is most easily compressed during stomping. The fact that the bottom of the second protrusion 123 is not lower than this point ensures that there is still an airflow channel near the air inlet 13 even when compressed. Extending its top to the root of the first protrusion 121 ensures that the air passage 51 is not flattened before the gas enters the air outlet 1211, allowing the gas to smoothly reach the gap in the air outlet 1211. In this way, regardless of whether the user lands on their forefoot or heel first, or from which direction the stomping pressure is transmitted, this strip-shaped protrusion can maintain at least one complete airflow channel from the air inlet 13 to the air outlet 1211 in the compressed area.

[0101] By adopting this implementation method, the strip-shaped protrusion provides a longitudinal support for the air passage 51, completely eliminating the possibility of air passage interruption due to local pressure, and significantly improving the functional reliability of the exhaust module throughout the entire gait cycle.

[0102] In some possible embodiments, such as Figure 2 and Figure 4-5 As shown, the end of the outer casing 1 located at the air inlet 13 protrudes from the end face of the outer casing 1.

[0103] As an optional implementation of the present invention, the air inlet 13 of the outer shell 1 is intentionally designed as an outwardly extending plug-in structure, with a noticeable protrusion compared to the main body end face of the outer shell 1. This protruding plug-in end can be inserted into the arc-shaped slot or notch 32 reserved on the edge of the heel of the shoe sole, serving as a quick positioning and initial fixation mechanism. Of course, those skilled in the art can further add anti-loosening structures such as barbs, corrugations, or steps to the surface of the plug-in end, making it difficult to pull out after insertion. After positioning, the final sealing is completed by bonding or injection molding edge sealing.

[0104] With this implementation, the protruding air inlet 13 is connected to the slot on the sole like a plug, which greatly simplifies the alignment and pre-fixation process during assembly, and is more conducive to product consistency during standardized production. At the same time, it increases the connection area between the outer shell 1 and the sole, which helps to improve the airtightness and mechanical strength at the interface between the outer shell 1 and the sole.

[0105] Example 3: Please see Figure 2 and Figure 8 The present invention also provides the following technical solutions: The air-conditioned shoe sole includes a lower sole 2, an upper sole 3, and an exhaust module as described in Embodiment 1 or 2. The lower sole 2 and the upper sole 3 are sealed together at the edge to form a breathing chamber 4. An elastic support body 5 is also provided inside the breathing chamber 4. An air inlet 31 is provided on the top surface of the upper sole 3 and at the forefoot, which passes through the breathing chamber 4. An air passage 51 for connecting the outer shell 1 is provided in the elastic support body 5 and / or the elastic support body 5 is made of an elastic porous material. The outer shell 1 is sealed together with the edge of the shoe sole.

[0106] As one possible implementation of this invention, considering that existing air-conditioned shoes have many different "breathing methods," such as the "external circulation" air-conditioned shoe solution, which can draw air in from inside the shoe and then expel it to the outside, allowing the gas to enter the shoe through the shoe opening (wearing opening) or breathable fabric, this scenario only requires one one-way exhaust valve; there is also a method that achieves external circulation through two one-way valves, i.e., one one-way valve is responsible for introducing gas from the outside space into the shoe, and the other one-way valve is responsible for introducing air from inside the shoe to the outside. In addition, there is an internal circulation solution, which introduces the gas inside the shoe into the breathing chamber 4, (after purification) and then releases the gas back into the shoe from another part of the sole, suitable for warm shoes in winter, this scenario also requires two one-way valves.

[0107] However, considering that internal circulation is usually not widely accepted and has a low market prospect due to its high cost, numerous alternatives, and short service life, this embodiment only considers the external circulation scenario, and is preferably applicable to the scenario with only one one-way exhaust valve. Of course, this embodiment is not limited to this.

[0108] When in use, after the user puts on the air-conditioned shoes, when the foot steps down, the forefoot fits against the air inlet 31, preventing the gas in the breathing chamber 4 from escaping through the air inlet 31. At the same time, the volume of the breathing chamber 4 contracts due to the weight of the human body, increasing the air pressure inside the breathing chamber 4. This causes the airflow to flow through the air passage 51 and / or the holes of the elastic support 5 itself, sequentially through the air inlet 31, the inner cavity of the outer shell 1, and the air outlet 1211. When the air pressure separates the soft elastic material of the first protrusion 121 located at the air outlet 1211, the airflow flows into the outer space of the shoe from the air outlet 1211. At this time, the air pressure in the outer shell 1 and the breathing chamber 4 decreases until it is balanced with the atmospheric pressure. The air outlet 1211 closes again due to the reaction of the soft elastic material of the first protrusion 121, and the external atmospheric pressure cannot open the air outlet 1211 from the outside of the first protrusion 121. When the user lifts their foot, the elastic support 5 expands back due to the reduction or even elimination of the user's weight, which restores the volume of the breathing chamber 4 and creates negative pressure inside the breathing chamber 4. At the same time, there is a certain gap between the forefoot and the sole surface, which opens the air inlet 31, thus drawing air into the breathing chamber 4. This creates an intermittent exhaust of gas from the shoe, with the frequency being the user's walking frequency.

[0109] It should be understood that this embodiment can also be used in cases with two one-way valves (i.e., the first protrusion 121 on the other housing 1 is located on the concave surface of the housing 1, and the other features remain unchanged), but it is sufficient to be applied to most air-conditioned shoe models.

[0110] Among them, the most common elastic support body 5 is sponge, and the specific design of the breathing cavity 4 is also a relatively mature design in the field. The specific composition of the entire sole can be (from bottom to top) lower sole 2, thermoplastic support plate 52, sponge, upper sole 3, or other solutions. This embodiment does not specifically limit this.

[0111] Regarding the upper sole 3 and the lower sole 2, since the definitions of outsole and midsole differ in the footwear industry, some manufacturers consider the outsole as the entire sole in this embodiment and the midsole as the layer next to the insole, while others consider the outsole as the layer in contact with the ground and the midsole as the top layer of the sole. However, the upper sole 3 and lower sole 2 described in this embodiment are not limited to the definitions that are confused in the industry. The upper sole 3 refers to the top layer of the breathing chamber 4, and the lower sole refers to the bottom layer of the breathing chamber 4. As for which specific component on the shoe they refer to, it is not limited, but depends only on the actual structure.

[0112] By adopting this implementation method, the arc-shaped thin-film exhaust module is completely integrated into the sole structure, forming a complete air path from air intake, temporary storage, diversion to exhaust. Moreover, the exhaust module itself is not embedded inside the sole, so it does not affect the uniformity and softness of the sole material, thus preventing users from experiencing a "foreign object" sensation while walking and not affecting their walking ability.

[0113] In some possible embodiments, such as Figure 8 As shown, the heel edge of the upper base 3 is provided with a notch 32, and the end of the outer shell 1 located at the second protrusion 123 is inserted into the notch 32 and sealed to the edge of the notch 32.

[0114] As an optional implementation of the present invention, the bottom base 2 has a notch 32 pre-reserved at its heel edge during manufacturing, which matches the shape of the insertion end of the outer shell 1. During assembly, the insertion end of the outer shell 1 is directly inserted into this notch 32 to complete the installation and positioning, and then sealed by subsequent plastic sealing or bonding processes. The notch 32 provides a clear installation reference for the outer shell 1, eliminating the need for repeated alignment and ensuring product consistency during mass production.

[0115] Limiting the ventilation module to the heel of the sole is more in line with human foot ergonomics, kinematics, aesthetics, and waterproofing. Of course, this layout is common, so we will not go into too much detail about it.

[0116] By adopting this implementation method, the plug-in positioning method of notch 32 reduces the assembly difficulty, improves production efficiency, and also ensures the sealing reliability of the interface.

[0117] Example 4: Please see Figure 3 The present invention also provides the following technical solutions: The air-conditioned shoe includes the air-conditioned shoe sole of embodiment 3, and also includes a shoe body 6 fixedly connected to the top edge of the shoe sole, with the concave surface, convex surface and / or side edge of the outer shell 1 fixedly connected to the shoe body 6.

[0118] In one optional implementation of this invention, the shoe body 6 and the top edge of the sole are connected as one piece using conventional stitching, bonding, or injection molding. The concave surface, convex surface, and / or side edges of the outer shell 1 are attached to the surface of the heel area of ​​the shoe body 6 and fixed by bonding, sewing, thermoforming, etc. Alternatively, the outer shell 1 can be directly used as the heel of the shoe body 6, with the side edges of the outer shell 1 sewn, bonded, or thermoformed onto the shoe body 6. In this way, the lower end of the outer shell 1 is fixed by the edge of the bottom sole 2, and the concave surface is pressed down by the shoe body 6, thus constraining both the upper and lower ends and preventing displacement or detachment during walking and exercise. At the same time, the outer shell 1 is covered by the shoe body 6, so it does not appear abrupt in appearance and maintains the overall aesthetics of the shoe.

[0119] By adopting this implementation method, the fixation of the shoe body 6 to the concave surface of the outer shell 1 and the fixation of the bottom 2 to the lower end of the outer shell 1 form a double constraint, which enables the exhaust module to work stably even during vigorous exercise, while also taking into account the overall appearance of the shoe.

[0120] Example 5: The present invention also provides the following technical solutions: The manufacturing method of air-conditioned shoes includes: The shell 1 is integrally formed into a hollow, arc-shaped sheet by injection molding, blow molding or 3D printing process, and a second protrusion 123 is formed on the inner wall of the shell 1. Place the concave surface of the outer shell 1 at the outer edge of the formed upper base 3 and seal the connection. The elastic support 5 is sandwiched between the lower sole 2 and the upper sole 3, and the edges are sealed by injection molding to obtain the air-conditioning shoe sole; Assemble shoe body 6 on the sole of the air-conditioned shoe to obtain the air-conditioned shoe.

[0121] As an optional implementation of this invention, a molding and manufacturing method for air-conditioned shoes is provided. First, based on production volume and cost, one of the following processes—injection molding, blow molding, or 3D printing—is selected to mold the elastic material into a hollow, arc-shaped thin-film shell 1 with a second protrusion 123 on the inner wall. Next, the concave surface of the shell 1 is fitted to the outer edge of the already molded upper sole 3, ensuring that the air inlet 13 of the shell 1 is aligned with the outlet of the breathing chamber 4 inside the upper sole 3, and then bonded or heat-sealed. Afterward, the elastic support 5 is placed in the breathing chamber 4 area between the lower sole 2 and the upper sole 3. After mold closing, the edges of the lower sole 2 and the upper sole 3 are completely sealed using an injection molding edge sealing process, forming a complete sole containing an air duct 51 and an exhaust module. Finally, the shoe body 6 is assembled with the sole to obtain the finished air-conditioned shoe.

[0122] Using this method, the molding of the outer shell 1 and the final sealing of the sole are independent yet closely connected. The process route is clear, suitable for standardized production, and can ensure the airtightness of the connection between the breathing chamber 4 and the outer shell 1.

[0123] In some possible embodiments, the injection-molded housing 1 includes: Two soft elastic material arc-shaped sheets are integrally formed by injection molding, namely inner layer 11 and outer layer 12. The outer layer 12 has a concave surface and a wedge-shaped first protrusion 121 formed on the arc-shaped convex surface. A linear or dot-shaped second protrusion 123 is formed on the lower part of the convex surface of the inner layer 11 or the lower part of the concave surface of the outer layer 12. The inner layer 11 and the outer layer 12 are sealed off except for the lower edge to form the outer shell 1.

[0124] As an optional implementation of the present invention, this method further refines step 1 of the injection molding of the outer shell. First, using a mold capable of simultaneously molding two thin sheets, an outer layer 12 with a first protrusion 121 and an inner layer 11 with a second protrusion 123 are injection molded. A recess is pre-set on the concave surface of the outer layer 12, causing its convex surface to naturally rise into a wedge-shaped protrusion; the second protrusion 123, either linear or dot-shaped, is simultaneously formed on the convex surface of the inner layer 11 or the concave surface of the outer layer 12 through the microstructure of the mold surface. After injection molding, the inner layer 11 and outer layer 12 are aligned and stacked, and then all edges except the lower edge are sealed using methods such as hot pressing, ultrasonic welding, or bonding. The unsealed lower edge naturally forms an air inlet 13, while the gap between the inner and outer layers 12 becomes an air passage.

[0125] Of course, those skilled in the art can also use two sets of molds to injection mold the inner layer 11 and the outer layer 12 of the outer shell 1 respectively. Although this is more complicated, it has the advantage of a more mature process and more reliable stability. This embodiment does not limit this method. Using this method, the inner and outer layers 12 of the shell with all functional structures can be obtained through a single injection molding process. The outer shell 1 can then be manufactured through a simple edge sealing process. This method has high production efficiency, good product consistency, and is particularly suitable for mass production.

[0126] The working principle and usage process of this invention: When the user walks, the sole of the foot steps on the upper 3, and the air inside the shoe enters the breathing chamber 4 through the air inlet 31 in the forefoot. The elastic support 5 is compressed and contracts, and the air pressure in the breathing chamber 4 increases, forcing the air along the air passage 51 or the pores of the porous material towards the air inlet 13 in the outer shell 1 at the heel. After the air enters the flat air passage 51 inside the outer shell 1, it is pushed open by the air pressure to the air outlet 1211 at the tip of the first protrusion 121 and discharged into the space outside the shoe.

[0127] When the foot is lifted, the elastic support 5 rebounds, creating negative pressure in the breathing chamber 4. The air outlet 1211 automatically closes under the elastic contraction force of the material, and the air inside the shoe is drawn back into the breathing chamber 4 through the air inlet 31, completing one gas exchange cycle. Throughout the walking process, the arc-shaped thin shell 1 always bends and deforms synchronously with the sole and shoe body 6, without generating hard points or stress concentrations, and the user can hardly feel the presence of the exhaust module.

[0128] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
