Description

Technical Field

[0001] This utility model relates to the field of shoe sole component manufacturing technology, and in particular to a waterproof and breathable device and shoe sole. Background Technology

[0002] In the field of waterproof and breathable structure manufacturing for footwear products, the inherent design flaws of traditional molds result in insufficient bonding stability between the waterproof fabric and hot melt adhesive, leading to poor adhesion. Furthermore, during high-temperature processing, traditional molds lack effective heat insulation, making the waterproof fabric susceptible to thermal deformation and performance degradation, thus hindering the synergistic optimization of waterproofness and breathability. These issues directly result in poor performance of waterproof and breathable footwear components, poor product quality stability, and insufficient durability, severely impacting the consumer experience and limiting the market competitiveness of related products. Summary of the Invention

[0003] This utility model provides a waterproof and breathable device and shoe sole to overcome the problems of poor adhesion and poor waterproof performance of existing waterproof and breathable accessories.

[0004] The present invention adopts the following technical solution:

[0005] A waterproof and breathable device includes a panel, a waterproof and breathable fabric, and a base plate stacked sequentially. The panel and the base plate each have corresponding breathable areas. The waterproof and breathable fabric has multiple through holes, which are distributed around the breathable areas and the periphery of the base plate. The panel is bonded to the base plate through the through holes. The breathable areas of the base plate have multiple breathable grids, and breathable channels are provided between the breathable grids. The breathable channels are circular, linear, or polygonal.

[0006] Furthermore, the aforementioned panel is a hot melt adhesive film or an epoxy resin film.

[0007] Furthermore, the aforementioned base plate is made of carbon fiber sheet, TPU material sheet, or nylon material sheet.

[0008] Furthermore, the diameter of the aforementioned circular hole is 1-3 mm, preferably 2 mm.

[0009] Furthermore, the aforementioned ventilation grille has an inclined panel structure, with an inclination angle of 45°-60°, preferably 45°.

[0010] The upper layer of the midsole has mounting holes, and breathable accessories are installed in the mounting holes. These breathable accessories have a crystalline breathable structure.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0012] 1. The sole of this utility model adopts a differentiated design with A and B molds forming in stages. The mold structure is scientific and reasonable, which can accurately control the forming size accuracy of shoe parts, effectively improve the stability of the production process and the consistency of products, and provide a reliable guarantee for large-scale production.

[0013] 2. This invention addresses the issue of high-temperature processing damaging the performance of waterproof and breathable fabrics in shoe soles. The breathable areas of the upper and lower molds in mold B are innovatively filled with heat-insulating and high-temperature-resistant materials such as aerogel, silicone, or EVA to form a directional heat-insulating and protective structure. This design precisely blocks the transmission path of high temperatures to the waterproof and breathable fabric, preventing problems such as thermal shrinkage, fiber structure damage, or waterproof coating failure during processing. It safeguards the original performance of the waterproof and breathable fabric from the source of the process, ensuring the long-term stability of the finished product's waterproof performance.

[0014] 3. This utility model's waterproof and breathable fabric utilizes laser perforation technology to form a controllable and uniformly distributed array of through holes. These through holes provide a "channel-like" conduction path for bonding the upper and lower panels, allowing the adhesive material to fully penetrate the interface and form an "anchoring" bonding structure. This significantly improves the interfacial bonding strength between the hot melt adhesive and the waterproof and breathable fabric / lower panel, increasing it by more than 30% compared to traditional structures. Furthermore, it works in conjunction with the grilles and ventilation channels in the lower panel's ventilation area to construct a "three-dimensional ventilation path." Ultimately, this achieves a synergistic breakthrough in the waterproof and breathable properties of shoe components, solving the industry pain point of traditional shoe components being "waterproof but not breathable, breathable but not waterproof." Simultaneously, it significantly improves product durability, extending service life by more than 50%, and optimizing the user's dry wearing experience. Attached Figure Description
