Description

Technical Field

[0001] This application relates to the field of footwear technology, specifically to a shoe and its sole. Background Technology

[0002] Shoes are clothing items used to protect and support the feet. They are typically made of durable materials such as leather, fabric, rubber, or synthetic materials. Generally, these materials are designed into shapes that can be worn on or secured to the foot to form a shoe. With technological advancements and increasing human needs, various types of shoes have emerged, such as running shoes, leather shoes, high heels, athletic shoes, sandals, and boots. Each type of shoe has its specific design and purpose to meet the wearing needs of different occasions and circumstances. In recent years, shoes that utilize miniature fans for ventilation (hereinafter referred to as ventilated shoes) have appeared on the market, specifically targeting people prone to sweating. It is important to understand that existing ventilated shoes all use miniature fans to replace the air inside and outside the shoe cavity to remove moisture from inside the shoe. For example, patent publication number CN222264539U, entitled "A Breathable Sports Shoe Sole" (hereinafter referred to as Prior Art 1), discloses a similar technology. Existing technology one involves setting multiple air inlets at the top of the sole, connected to the shoe cavity, and multiple air outlets on the sides of the sole. A miniature fan draws air from the shoe cavity through the air inlets and exhausts it through the air outlets to achieve ventilation. It should be noted that shoe soles are generally made of flexible materials. Directly placing air inlets and outlets on the sole can easily block the connection between them due to the act of stepping on the foot, resulting in poor ventilation during walking. Utility Model Content

[0003] The purpose of this application is to provide a shoe and its sole to solve the technical problem that the connection between the air inlet and outlet is easily blocked when making holes directly in the sole, resulting in poor ventilation in the shoe.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] Firstly, this application proposes a technical solution for a shoe sole, which is applied to a shoe, the shoe including a sole and an upper; a shoe cavity for accommodating the foot is formed between the sole and the upper; as a specific solution in this application, a first groove is provided at the toe of the sole; the sole further includes:

[0006] A protective shell is disposed in the first groove; the protective shell is also provided with multiple air inlets; in use, the air inlets connect the interior of the protective shell with the shoe cavity;

[0007] An exhaust pipe is provided on the protective shell; the exhaust pipe is used to connect the inside of the protective shell with the outside of the sole.

[0008] A miniature fan is disposed inside the protective shell; the miniature fan is used to displace the air inside and outside the shoe cavity through the exhaust pipe and various air inlets.

[0009] As a specific embodiment of the technical solution in this application, the sole is further provided with a second groove, and the sole also includes a power source and a power cord, with the power source disposed in the second groove; the power cord is embedded inside the sole and is used to electrically connect the power source and the micro fan.

[0010] As a specific embodiment of the technical solution in this application, the second groove is disposed at the heel of the shoe sole.

[0011] As a specific embodiment of the technical solution in this application, the opening of the second groove is located at the top of the sole.

[0012] As a specific solution in this application, the sole is further provided with a sealing cap, which is used to seal the opening of the second groove.

[0013] As a specific solution in this application, the first groove extends through the sole along its thickness direction, and the bottom of the sole is sealed with a sealant layer.

[0014] As a specific embodiment of the technical solution in this application, a collecting section is further provided between the protective shell and the exhaust pipe, and the inner diameter of the collecting section decreases along a first direction; the first direction is parallel to the airflow direction in the collecting section, and the first direction points from the protective shell to the exhaust pipe.

[0015] As a specific embodiment of the technical solution in this application, the exhaust pipe is further provided with a control valve, which is used to control the opening and closing of the exhaust pipe.

[0016] As a specific solution in this application, the miniature fan is used to draw air from outside the protective shell into the interior of the protective shell through the air inlet, and to discharge the air inside the protective shell through the exhaust pipe; the control valve includes a one-way valve, and the one-way valve includes a duckbill one-way valve.

[0017] As a specific solution in this application, the sole further includes a first duckbill one-way valve and a second duckbill one-way valve; the input ends of the first duckbill one-way valve and the second duckbill one-way valve are both connected to the exhaust pipe; the output end of the first duckbill one-way valve faces one side of the sole, and the output end of the second duckbill one-way valve faces the other side of the sole.

[0018] Secondly, this application proposes a shoe that includes a sole as described in any of the first aspects.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] This application, through the design of a protective shell with air inlets and outlets, ensures that the shell will not collapse or close even when the user steps directly on it, thus preventing blockage of the air inlet and outlet. In other words, the sole of the shoe proposed in this embodiment can maintain ventilation for a long time. Furthermore, in this embodiment, the protective shell is located at the toe, which is generally a less stress-bearing area of ​​the sole, further making it difficult for the connection between the air inlet and outlet to be blocked by stepping.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that in the description of this application, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0038] To address the technical problem mentioned in the background art, where directly creating openings in the sole results in poor ventilation in shoes, this application proposes an embodiment of a shoe sole. It should be noted that the shoe sole proposed in this embodiment is applied to a shoe. In the prior art, shoes generally include a sole and an upper, with a cavity formed between the sole and the upper to accommodate the foot. Since shoes are a mature prior art, the structure of the shoe will not be described in detail in this embodiment of the application.

[0039] It should be noted that this application does not limit the application scenarios of the shoe soles proposed in the embodiments. That is, the shoe soles proposed in the embodiments of this application can be applied to any type of shoe. For example, the shoe soles proposed in the embodiments of this application can be applied to relatively stuffy leather shoes, sneakers, or boots to improve the ventilation and breathability of these shoes. Of course, to make the shoes more fashionable or to achieve other purposes, the shoe soles proposed in the embodiments of this application can also be applied to shoes with good breathability (e.g., sandals or mesh shoes).

[0040] Specifically, in the embodiments of this application, such as Figure 1 and Figure 2 As shown, a first groove 12 is provided at the toe of the sole 1. The sole 1 also includes a protective shell 31, an exhaust pipe 34, and a miniature fan 33. The protective shell 31 is disposed in the first groove 12. Figure 5 As shown, the protective shell 31 is also provided with multiple air inlets 32, which, during use, connect the interior of the protective shell 31 to the shoe cavity. Figure 5 As shown, an exhaust pipe 34 is disposed on the protective shell 31, and the exhaust pipe 34 is used to connect the interior of the protective shell 31 with the exterior of the sole 1. Figure 5 As shown, a miniature fan 33 is disposed inside the protective housing 31. The miniature fan 33 is used to draw air from outside the protective housing 31 into the interior of the protective housing 31 through the air inlet 32, and to discharge the air inside the protective housing 31 through the exhaust pipe 34.

[0041] When in use, if the miniature fan 33 is turned on, the movement path of the air inside the shoe cavity is as follows: Figure 5 The path F is shown in the diagram. The hot and humid air inside the shoe cavity first enters the interior of the protective shell 31 through the air inlet 32, and then is discharged to the outside of the protective shell 31 (that is, discharged to the outside of the shoe cavity) through the exhaust pipe 34.

[0042] Of course, in other embodiments of this application, the miniature fan 33 can also be used to draw air from outside the protective shell 31 into the interior of the protective shell 31 through the exhaust pipe 34, and blow air from inside the protective shell 31 into the shoe cavity through the air inlet 32. In other words, in the embodiments of this application, as long as the miniature fan 33 can achieve air exchange between the inside and outside of the shoe cavity through the exhaust pipe 34 and each air inlet 32, there are no restrictions on the specific working method of the miniature fan 33.

[0043] It is important to note that in shoes with poor breathability, such as leather shoes or boots, the toe area has the worst breathability and is the most stuffy. In this embodiment, the first groove 12 is located at the toe, and the protective shell 31 is disposed within the first groove 12, meaning the protective shell 31 is located at the toe. In other words, in this embodiment, the micro-fan 33 located within the protective shell 31 can effectively replace the air at the toe. Extensive testing by the inventors has shown that effectively replacing the air at the toe significantly improves the shoe's ventilation. In other words, the sole 1 proposed in this embodiment can significantly improve the shoe's ventilation. Furthermore, the toe area is a frequently used area for toe movement, making it prone to sweating and bacterial growth. The protective shell 31 being located at the toe, meaning the air inlet 32 ​​is concentrated there, allows the micro-fan 33 to forcefully expel the hot and humid air from the toe through the air inlet 32, inhibiting bacterial growth.

[0044] It is important to note that due to the limited space within the shoe itself, most ventilated shoes use miniature fans, meaning they have limited power. In this embodiment, the fan is positioned at the toe of the shoe, and air intake holes are only provided on the protective shell. This allows the miniature fan to generate greater air suction at the toe, further enhancing the air exchange effect at that location.

[0045] The embodiments of this application, through the provision of a protective shell with air inlets and exhaust pipes, ensure that the protective shell will not collapse or close even when the user steps directly on it, thus preventing blockage of the air inlet and exhaust pipe connection. In other words, the sole of the shoe proposed in this application can maintain the shoe's ventilation effect for a long time. Furthermore, in this embodiment, the protective shell is located at the toe, which is generally a less stress-bearing part of the sole, further making it difficult for the connection between the air inlet and exhaust pipe to be blocked by stepping.

[0046] In the embodiments of this application, no limitations are placed on the shape and structure of the protective shell. For example, the protective shell can be as follows: Figure 1 and Figure 2 The circular shell shape shown can also be as follows: Figure 7 The shape is a square shell.

[0047] In the embodiments of this application, there are no restrictions on the material of the protective shell. For example, the protective shell can be made of metal or plastic. In order to make the protective shell have a certain degree of flexibility and avoid the material being too hard and hurting the feet, a rubber layer (not shown in the figure) can be wrapped around the outside of the protective shell.

[0048] It should be noted that the miniature fan 33 requires power to start. In this embodiment, an external power supply can be used to power the miniature fan 33. For example, a Universal Serial Bus (USB) can be configured for the miniature fan 33, allowing it to be powered by a power bank. However, it should be noted that if an external power supply is used, the power cable (e.g., the USB cable) will be exposed, which is inconvenient. It should also be noted that connecting the miniature fan 33 and the power bank via USB is a mature technology and will not be elaborated upon here.

[0049] To improve convenience, in one embodiment of this application, such as Figure 1 and Figure 2 As shown, the sole 1 may also be provided with a second groove 11. The sole 1 also includes a power supply 2 and a power cord 4, with the power supply 2 disposed in the second groove 11. Figure 3 As shown, the power cord 4 is embedded inside the sole 1 of the shoe. The power cord 4 is used to electrically connect the power supply 2 and the miniature fan 33. It should be noted that connecting the power supply and the miniature fan electrically via a power cord is a mature technology, which will not be elaborated here.

[0050] It should be noted that in other embodiments of this application, in order to facilitate the maintenance of the power cord 4, the power cord 4 may not be pre-embedded inside the sole 1, but a wire channel (not shown in the figure) is provided inside the sole 1, and the power cord 4 can be electrically connected to the power supply 2 and the miniature fan 33 through the wire channel.

[0051] In the embodiments of this application, there are no restrictions on the type of power source 2. For example, power source 2 can be any one of alkaline power source, zinc-carbon power source, lithium power source, nickel-metal hydride power source, or lead-acid power source. In order to enable the recycling of power source 2, power source 2 can also be a rechargeable power source. Rechargeable power sources are mature technologies and will not be described in detail here.

[0052] In the embodiments of this application, the position of the second groove 11 is not limited. For example, the second groove 11 can be located in the middle of the sole 1 or at the toe. In order to make the second groove 11 have a large space, and thus be able to accommodate a larger power supply 2 (i.e., a larger capacity), so that the power supply 2 has sufficient battery life, in one embodiment of this application, such as Figure 3 and Figure 4 As shown, the second groove 11 can be provided at the heel of the sole 1. It should be noted that since the sole 1 is thicker at the heel, providing the second groove 11 at the heel can make the second groove 11 have a larger accommodating space.

[0053] It should be noted that if the second groove 11 is located at the heel of the shoe sole 1, the power supply 2 will be subjected to greater pressure during use. To prevent the power supply 2 from being damaged by being stepped on, in one embodiment of this application, a protective casing of metal (e.g., stainless steel or aluminum alloy) can be provided for the power supply 2.

[0054] In one embodiment of this application, the power supply 2 can be pre-embedded in the sole 1 of the shoe. To facilitate the maintenance, replacement, or charging of the power supply 2, in one embodiment of this application, the second groove 11 also has an opening, through which the power supply 2 can be removed from the second groove 11 during use.

[0055] In order to seal the opening of the second groove 11, in one embodiment of this application, such as Figure 4 As shown, the sole 1 is also provided with a sealing cap 13, which is used to seal the opening of the second groove 11. In this embodiment, there are no restrictions on the connection method between the sealing cap 13 and the sole 1. For example, the sealing cap 13 can be snapped into the sole 1 (the snap-fit ​​structure between the sealing cap 13 and the sole 1 can be as shown in the sealing cap in the patent document with publication number CN203698926U); the sealing cap 13 can also be hinged to the sole 1. Hinging the cap to an object (e.g., a fuel tank cap or the back cover of a toy battery) is a mature technology and will not be elaborated here.

[0056] To prevent rainwater from entering the second groove 11 through the opening in rainy weather, in one embodiment of this application, such as... Figure 4 As shown, the opening of the second groove 11 is located at the top of the sole 1. It should be clear that if the opening of the second groove 11 is located at the top of the sole 1, rainwater outside the shoe cavity will have difficulty entering the interior of the second groove 11 through the opening.

[0057] To facilitate the collection of air blown out by the miniature fan 33 to the exhaust pipe 34 for discharge, in one embodiment of this application, such as Figure 7 and Figure 8 As shown, a converging section 35 may also be provided between the protective housing 31 and the exhaust pipe 34, the inner diameter of the converging section 35 decreasing along a first direction. The first direction is parallel to the airflow direction in the converging section 35, and the first direction points from the protective housing 31 to the exhaust pipe 34 (i.e., as shown). Figure 8(Direction E shown). It should be noted that, since the inner diameter of the collecting section 35 decreases along the first direction, the collecting section 35 is able to collect the air blown out by the miniature fan 33 along the first direction to the exhaust pipe 34.

[0058] In order to prevent rainwater outside the shoe cavity from entering the interior of the protective shell 31 through the exhaust pipe 34 during rainy weather, or to prevent cold air outside the shoe cavity from entering the interior of the shoe cavity through the exhaust pipe 34 during cold winter, in one embodiment of this application, a control valve can also be provided in the exhaust pipe 34 to control the opening and closing of the exhaust pipe 34.

[0059] In use, during rainy weather or cold winter, the exhaust pipe 34 can be closed using the control valve, thus cutting off the connection between the inside of the protective shell 31 and the outside of the shoe cavity. In other words, if the exhaust pipe 34 is closed by the control valve, rainwater or cold air outside the shoe cavity cannot enter the inside of the protective shell 31 or the inside of the shoe cavity through the exhaust pipe 34. It should be noted that controlling the opening and closing of the pipe (i.e., the exhaust pipe 34) using a valve (i.e., the control valve) is a mature technology and will not be elaborated upon here.

[0060] In the embodiments of this application, there are no restrictions on the type of control valve. For example, the control valve can be a solenoid valve or a shut-off valve.

[0061] It should be noted that if the control valve is a solenoid valve or a shut-off valve, and the exhaust pipe 34 is closed using the control valve, then even if the miniature fan 33 is turned on, it will not be able to effectively replace the hot and humid air inside the shoe cavity. In order to prevent rainwater or cold and humid air from entering the shoe cavity through the exhaust pipe 34, and to enable the miniature fan 33 to replace the hot and humid air inside the shoe cavity, in one embodiment of this application, the control valve can be a one-way valve.

[0062] It is important to understand that if the control valve is a one-way valve, rainwater or cold air outside the shoe cavity will have difficulty entering the interior of the protective shell 31 (i.e., the interior of the shoe cavity) through the one-way valve. Meanwhile, the hot and humid air inside the shoe cavity can be discharged from the shoe cavity through the exhaust pipe 34 by the one-way valve driven by the micro fan 33.

[0063] To reduce the complexity of control valves and manufacturing costs, in one embodiment of this application, such as Figure 9 As shown, the one-way valve 36 can be a duckbill one-way valve.

[0064] In the embodiments of this application, such as Figure 9As shown, the air discharged from the exhaust pipe 34 can be guided to the front of the shoe toe via the duckbill one-way valve, and then discharged from the front of the shoe toe. It should be noted that in practical applications, due to limited space at the front of the toe of some shoes (e.g., leather shoes), it is not possible to install an exhaust pipe 34 and a duckbill one-way valve. Therefore, it is possible to... Figure 11 The exhaust pipe 34 extends towards the arch of the foot, allowing exhaust to be released from the bottom of the sole 1. The arch area has ample space, providing sufficient room for the exhaust pipe 34 and the duckbill one-way valve.

[0065] It should be noted that most people habitually tiptoe when walking on wet surfaces, both to avoid splashing water and to prevent their shoes from getting wet or dirty. To prevent the output of the duckbill one-way valve from being directly immersed in rainwater during tiptoeing, thus avoiding the risk of external rainwater entering the exhaust pipe 34 through the duckbill one-way valve, in one embodiment of this application, as... Figure 10 As shown, the sole 1 may also include a first duckbill one-way valve 37 and a second duckbill one-way valve 38. The input ends of the first duckbill one-way valve 37 and the second duckbill one-way valve 38 are both connected to the exhaust pipe 34. The output end of the first duckbill one-way valve 37 faces one side of the sole 1, while the output end of the second duckbill one-way valve 38 faces the other side of the sole 1.

[0066] It is important to note that, unlike the method of venting air from the shoe cavity through the toe of the shoe via a duckbill one-way valve, this embodiment uses a first duckbill one-way valve 37 and a second duckbill one-way valve 38 to vent air from the sides of the sole 1. In application scenarios where rainwater does not submerge the sole 1, normal walking is unlikely to cause the output ends of the first duckbill one-way valve 37 and the second duckbill one-way valve 38 to be immersed in rainwater. In other words, this embodiment reduces the risk of rainwater entering the vent pipe 34 through the first duckbill one-way valve 37 or the second duckbill one-way valve 38 during walking.

[0067] In the embodiments of this application, no restrictions are placed on the outlet positions of the first duckbill check valve 37 and the second duckbill check valve 38. For example, the outlet positions of the first duckbill check valve 37 and the second duckbill check valve 38 can be as follows: Figure 10 The image shows the two sides near the toe of the shoe, which can also be seen as... Figure 12 The image shows the two sides near the arch of the shoe.

[0068] To prevent rainwater from entering the exhaust pipe 34 through the duckbill check valve due to its high hydrophilicity and capillary effect, in one embodiment of this application, the duckbill check valve can be made of a hydrophobic material, or a hydrophobic coating or membrane can be disposed inside the duckbill check valve. It should be noted that hydrophobic materials, hydrophobic coatings, and hydrophobic membranes are all mature technologies and will not be elaborated upon here.

[0069] In an embodiment of this application, the opening of the first groove 12 can be located at the top of the sole 1. During use, the protective shell 31 with the miniature fan 33 is installed into the interior of the first groove 12 through this opening. It should be noted that the miniature fan 33 is a consumable part that requires replacement and maintenance during long-term use. If the protective shell 31 can only be removed from the first groove 12 through the opening at the top of the first groove 12, then the connection between the upper and the sole 1 needs to be disassembled before replacing or maintaining the miniature fan 33. It should be noted that the connection between the upper and the sole 1 is generally complex, and disassembly and reconnection are cumbersome. To reduce the difficulty of replacing and maintaining the miniature fan 33, in one embodiment of this application, such as... Figure 6 As shown, the first groove 12 can penetrate the sole 1 along its thickness direction. If a miniature fan 33 needs to be installed, the protective shell 31 with the miniature fan 33 is installed from the bottom of the sole 1 into the first groove 12, and then a sealing layer 14 is formed on the bottom of the sole 1 with glue to seal the bottom of the first groove 12.

[0070] When in use, if the miniature fan 33 needs to be inspected or replaced, a tool (e.g., a utility knife) can be used to cut open the sealing layer 14, and the protective shell 31 can be removed for inspection or replacement. After the inspection or replacement is completed, the protective shell 31 is installed into the first groove 12, and the first groove 12 is sealed again with glue. Compared to the need to disassemble and reconnect the sole and upper, cutting open the sole 1 and sealing it with glue is a simpler operation.

[0071] It should be noted that there are many types of adhesives used to seal the sole 1, which will not be listed in detail here. For example, the adhesive can be hot melt adhesive or sealant. Hot melt adhesive and sealant used to bond and repair holes in the sole are both mature technologies, and will not be elaborated on here.

[0072] The embodiments of this application, through the provision of a protective shell with air inlets and exhaust pipes, ensure that the protective shell will not collapse or close even when the user steps directly on it, thus preventing blockage of the air inlet and exhaust pipe connection. In other words, the sole of the shoe proposed in this application can maintain the shoe's ventilation effect for a long time. Furthermore, in this embodiment, the protective shell is located at the toe, which is generally a less stress-bearing part of the sole, further making it difficult for the connection between the air inlet and exhaust pipe to be blocked by stepping.

[0073] Having described the shoe sole proposed in the embodiments of this application, the following describes a shoe proposed in this application, which includes the shoe sole 1 proposed in any of the embodiments described above.

[0074] The sole of this embodiment features a protective shell with air inlets and outlets. Even when a user steps directly on the protective shell, it will not collapse or close, ensuring the connection between the air inlets and outlets remains unblocked. In other words, the sole of this embodiment maintains good ventilation for a long time. Furthermore, in this embodiment, the protective shell is located at the toe, which is generally a low-stress area on the sole, further preventing the connection between the air inlets and outlets from being blocked by foot pressure.

[0075] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
