Description

Technical Field

[0001] This utility model belongs to the field of sports shoe technology, specifically relating to a waterproof sports shoe. Background Technology

[0002] In the development of athletic shoes, balancing waterproofing and breathability has always been a technical challenge. This stems from the inherent contradiction between the technical requirements of "building a barrier" against external threats and "ensuring a passageway" internally. To achieve effective waterproofing, the industry commonly uses dense films such as waterproof coatings or laminated polyurethane (TPU) on the upper. While this blocks external liquid water intrusion, it also hinders the expulsion of water vapor from the shoe, leading to sweat buildup and stuffy, uncomfortable feet. Conversely, using porous materials like mesh to enhance breathability promotes airflow and moisture expulsion, but their porous structure also allows rain and snow to penetrate, making it difficult to meet the protection needs of all-weather and complex environments. Therefore, how to block liquid water while maintaining the smooth expulsion of water vapor has become a core problem urgently needing to be solved in the field of waterproof athletic shoes. Utility Model Content

[0003] The present invention aims to provide a waterproof sports shoe that solves the technical problem that existing sports shoes cannot simultaneously achieve waterproofness and breathability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A waterproof sports shoe includes a shoe body, the upper of which is made of a waterproof material, and a plurality of mounting holes are provided on the side of the shoe body, the mounting holes penetrating the shoe body, and each mounting hole is provided with a breathable module.

[0006] The breathable module includes a base fixed in the mounting hole. The base is used to install the breathable component, with the inside of the sports shoe body as the inner side and the outside of the sports shoe body as the outer side. The breathable component has several airflow channels that pass through its inner and outer ends, and the inner end of the breathable component is covered with a waterproof and breathable membrane.

[0007] Furthermore, the mounting hole is a stepped hole, and its outer end diameter is larger than its inner end diameter; the shape of the base is adapted to the mounting hole; the base has an inner hole, which is a stepped hole.

[0008] The ventilated component includes a cylindrical body and a limiting end face. The cylindrical body fits tightly with the small-diameter portion of the stepped hole in the base, and the limiting end face matches the large-diameter portion of the stepped hole in the base.

[0009] Furthermore, the small-diameter portion of the stepped hole of the base is provided with internal threads, the outer wall of the cylindrical part is provided with external threads, and the cylindrical part is connected to the base by means of threads; the limiting end face is provided with a cross groove for tool screwing.

[0010] Furthermore, the inner wall of the small-diameter portion of the stepped hole of the base is provided with a conical retaining ring, which is made of soft synthetic resin. The conical retaining ring is conical in shape, and its outer end inner diameter is larger than its inner end inner diameter. The outer wall of the cylinder portion of the venting component is provided with an annular groove, which cooperates with the conical retaining ring.

[0011] Furthermore, the airflow channel is frustum-shaped, and the inner diameter of the airflow channel is smaller than the outer diameter.

[0012] Furthermore, the impermeable material is thermoplastic polyurethane.

[0013] Furthermore, the waterproof and breathable membrane is an expanded polytetrafluoroethylene membrane or a thermoplastic polyurethane breathable membrane, and the waterproof and breathable membrane is fixed to the inner end face of the breathable component by hot pressing or adhesive layer.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting a breathable module on the side of the athletic shoe body, this invention achieves effective air circulation between the inside and outside of the shoe, maintaining good breathability while preventing external moisture from seeping in. The breathable module is installed through the cooperation of the base and the breathable component, resulting in a compact structure and reliable sealing. The connection method of the conical retaining ring and the annular groove ensures a secure connection while facilitating disassembly and maintenance. The waterproof and breathable membrane ensures that the inside of the shoe remains dry and comfortable even in rainy or humid environments. Compared with traditional waterproof athletic shoes, this invention balances waterproof and breathable performance, improving wearing comfort and applicability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The present invention will be further described in detail below with reference to the embodiments.

[0024] Example 1

[0025] like Figure 1-4 As shown, this embodiment provides a waterproof sports shoe, including a sports shoe body 1. The upper of the sports shoe body 1 is made of a waterproof material to effectively block external liquid water. The waterproof material is thermoplastic polyurethane (TPU), which has good flexibility, abrasion resistance and waterproof performance, and can be integrally prepared with the upper by hot pressing.

[0026] The side of the athletic shoe body 1 is provided with several mounting holes 2, which penetrate the athletic shoe body 1. Each mounting hole 2 is provided with a ventilation module 3. By setting ventilation modules 3 on both sides of the shoe body, the moisture accumulated inside the shoe can be discharged through the modules, thereby improving wearing comfort.

[0027] The breathable module 3 includes a base 4 fixed within the mounting hole 2, which is used to mount the breathable component 5. With the inside of the shoe body 1 as the inner side and the outside as the outer side, the breathable component 5 has several airflow channels 6 penetrating its inner and outer ends, and the inner end of the breathable component 5 is covered with a waterproof and breathable membrane 7. Through the selective permeability of the waterproof and breathable membrane 7, it can block external liquid water from seeping in while allowing internal water vapor to escape, achieving a balance between waterproofing and breathability. Preferably, the waterproof and breathable membrane 7 is an expanded polytetrafluoroethylene (ePTFE) membrane or a thermoplastic polyurethane (TPU) breathable membrane. The waterproof and breathable membrane 7 is fixed to the inner end face of the breathable component 5 by hot pressing or adhesive layering. The ePTFE membrane has a microporous structure, allowing water vapor to pass through while blocking liquid water; while the TPU breathable membrane achieves moisture permeability through the hydrophilic diffusion of its molecular chains. Both membranes can achieve a balance between waterproofing and breathability.

[0028] This structural design allows the athletic shoes of this embodiment to maintain good protection and comfort performance in rainy or high-humidity environments.

[0029] Furthermore, the mounting hole 2 is a stepped hole, and its outer diameter is larger than its inner diameter. The shape of the base 4 is adapted to the mounting hole 2. The base 4 has an inner hole, which is a stepped hole, used to form a multi-level positioning structure.

[0030] The ventilated component 5 includes a cylindrical body 8 and a limiting end face 9. The cylindrical body 8 fits tightly with the small-diameter portion of the stepped hole in the base 4, and the limiting end face 9 matches the large-diameter portion of the stepped hole in the base 4. This structural design ensures that the ventilated component 5 is stably positioned after installation and prevents it from loosening during use.

[0031] The inner wall of the small-diameter portion of the stepped hole in the base 4 is provided with a conical retaining ring 10, which is made of soft synthetic resin. The conical retaining ring 10 has a conical ring structure, with its outer end inner diameter being larger than its inner end inner diameter. The outer wall of the cylindrical portion 8 of the venting component 5 is provided with an annular groove 11, which mates with the conical retaining ring 10. When the venting component 5 is pressed into the base 4, the soft, conical retaining ring 10 undergoes elastic deformation. When the venting component 5 is pressed into place, the conical retaining ring 10 springs back and engages with the annular groove 11, achieving a locking mechanism.

[0032] Example 2

[0033] Based on Example 1, this example provides another installation structure for the breathable module 3.

[0034] like Figure 5 As shown, the small-diameter portion of the stepped hole in the base 4 is provided with internal threads, and the outer wall of the cylindrical part 8 is provided with external threads. The cylindrical part 8 is connected to the base 4 by threads. The threaded connection allows for detachable installation, facilitating the replacement or maintenance of the venting component 5 later.

[0035] The limiting end face 9 is provided with a cross groove for tool tightening, so that screwdrivers or other tools can be used to tighten or loosen the parts during installation or disassembly. This structure not only improves the reliability of assembly, but also enhances the convenience of maintenance.

[0036] Similar to Example 1, the inner end of the breathable component 5 is covered with a waterproof and breathable membrane 7, which can be an expanded polytetrafluoroethylene membrane or a thermoplastic polyurethane breathable membrane, and is fixed to the inner end face of the breathable component 5 by hot pressing or adhesive layer.

[0037] This embodiment replaces the snap ring structure with a threaded connection, so that the breathable module 3 can not only meet the functions of waterproof and breathable, but also have stronger maintainability and reusability, making it suitable for different manufacturing processes and usage scenarios.

[0038] Example 3

[0039] Based on Embodiments 1 and 2, this embodiment further optimizes the airflow channel 6, which is frustum-shaped and has a smaller inner diameter than the outer diameter. This structural design facilitates a one-way airflow effect, promotes the smooth discharge of moisture from inside the shoe, and prevents the infiltration of external liquids.
