Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a side-mounted one-way exhaust shoe with a built-in air duct. Background Technology

[0002] Shoes are wearable items that people wear on their feet, which have functions such as protecting the feet, facilitating walking and exercise, keeping warm, and decorating. They are usually composed of parts such as soles and uppers. Through the material and structural design adapted to different scenarios, they meet various usage needs such as daily life, sports, and outdoor activities. At the same time, they also carry additional attributes of culture, fashion, and identity expression. Current shoes mostly have closed or simple ventilation holes on the sides, which cannot achieve directional ventilation. During exercise, heat and moisture generated by the feet easily accumulate inside the shoe, causing stuffiness and dampness. Moreover, water and dust can easily enter through the ventilation holes, making it difficult to balance breathability and waterproofing / dustproofing, thus affecting the wearing experience. Current soles and anti-slip pads are mostly glued or fixed with a single buckle. With long-term bending, the glue is prone to coming unglued and the edges to peel up, and water and dust can seep into the gaps. In addition, there is no rigid support structure, and the fit is easily damaged by stepping and squeezing, resulting in poor sealing durability. It is difficult to balance waterproofing / dustproofing and impact resistance, thus affecting the lifespan of the shoes. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a side-mounted one-way exhaust shoe with a built-in air guide groove.

[0004] The present invention is implemented as follows: a side-mounted one-way exhaust shoe with built-in air guide groove is constructed. The device includes an upper, the bottom of which is integrally die-cast with an exhaust mechanism, and the top of which is provided with shoelaces. The exhaust mechanism includes a sole, with the sole integrally die-cast at the bottom of the upper. The top surface of the sole has a biomimetic leaf-shaped air channel, with a first one-way valve embedded within it for directional airflow. A first air hole communicating with the inner cavity of the sole is located at the rear bottom of the air channel. An air bladder is integrated at the rear end of the top surface of the sole. A non-woven fabric is bonded to the top surface of the sole, and an insole is bonded to the top of the non-woven fabric. Both the non-woven fabric and the insole have second air holes arranged in a leaf-shaped array. An anti-slip pad is fitted to the bottom surface of the sole, with a second one-way valve embedded in the outer wall of the anti-slip pad. A sealing mechanism is integrally die-cast around the outer circumference of the top surface of the anti-slip pad.

[0005] Preferably, the sealing mechanism includes arc-shaped flexible expansion teeth. The outer circumference of the top surface of the anti-slip pad is integrally die-cast with arc-shaped flexible expansion teeth. An integrated TPU waterproof layer is sprayed onto the outer side of the arc-shaped flexible expansion teeth. The outer side of the joint between the sole and the anti-slip pad is covered with a silicone sealing strip. A circumferential annular rigid limiting frame is provided on the top surface of the anti-slip pad and the inner area of ​​the arc-shaped flexible expansion teeth. A polyurethane foam block is elastically embedded in the central area of ​​the circumferential annular rigid limiting frame. A top support column is arranged in an array inside the polyurethane foam block. A high-elastic dense cushioning substrate layer is compositely bonded to the top surface of the polyurethane foam block. A wear-resistant and tear-resistant reinforcing fabric layer is compositely bonded to the bottom surface of the polyurethane foam block.

[0006] Preferably, the second air hole and the air guide groove are precisely aligned and matched, and the leaf-shaped outline of the air guide groove is arranged in a gradually narrowing manner from the toe to the midsection of the shoe.

[0007] Preferably, the apertures of the first and second air holes are matched in a stepped manner, the airbag is connected to the air guiding path of the air guiding groove, and the airbag can deform with stepping to realize the synchronous compression and release of the internal gas, providing active airflow power for the air guiding system.

[0008] Preferably, the second one-way valve is vented from the inner cavity of the shoe sole outwards, while simultaneously blocking the reverse intrusion of external mud and water. The air guide groove, the first air hole, and the second air hole are formed in one piece using in-mold injection molding to ensure the airtightness of the air guide path.

[0009] Preferably, the arc-shaped flexible expansion teeth are evenly spaced along the outer periphery of the top surface of the anti-slip pad. The arc-shaped flexible expansion teeth are integrally molded from elastic modified plastic material and adaptively expand outward when assembled with the shoe sole to achieve bidirectional clamping mechanical locking.

[0010] Preferably, the TPU waterproof layer is formed on the outer surface of the arc-shaped flexible expansion teeth using a plasma spraying process, forming a dense waterproof membrane layer, which together with the silicone sealing strip constructs a double outer water barrier.

[0011] Preferably, the inner wall of the circumferential annular rigid limiting frame is fitted with the outer circumferential contour of the polyurethane foam block to achieve lateral deformation constraint and circumferential positioning of the polyurethane foam block.

[0012] Preferably, the two ends of the top support column abut against a high-elastic dense buffer substrate layer and a wear-resistant and tear-resistant reinforced fabric layer, respectively, to form a rigid support frame.

[0013] Preferably, the high-elastic dense buffer substrate layer is a high-density elastic foam material layer, which is bonded to the top surface of the foamed polyurethane block by hot melt adhesive film, thus having both pressure dispersion and interface anti-slip functions.

It features an ventilation mechanism where the foot's stomping and lifting motion compresses and releases an airbag. The pressure difference then drives a first and a second one-way valve to achieve one-way ventilation, ensuring the directional expulsion of hot and moist air from the shoe while effectively blocking external mud, water, and dust, thus keeping the shoe interior dry. A sealing mechanism is also included, using multiple material layers to achieve a long-term, stable waterproof and dustproof seal between the sole and the anti-slip pad, preventing water seepage, dust ingress, and adhesion failure.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The embodiments of this invention will now be described according to its overall structure.

[0020] Example 1:

[0021] Please see Figures 1-3 The present invention provides a side-mounted one-way exhaust shoe with built-in air guide groove, including an upper 1, an exhaust mechanism 2 integrally die-cast at the bottom of the upper 1, and a shoelace 3 at the top of the upper 1.

[0022] The exhaust mechanism 2 includes a sole 21. The bottom of the upper 1 is a one-piece die-cast sole 21. A biomimetic leaf-shaped air channel 22 is opened on the top of the sole 21. This air channel 22 gradually narrows from the toe towards the midfoot. A first one-way valve 23 is installed inside the air channel 22, ensuring that gas can only flow in one direction. A first air hole 24 is opened on the rear side of the bottom of the air channel 22, which connects to the internal space of the sole 21. An air bladder 25 is installed at the rear end of the sole 21. The air bladder 25 is connected to the air channel 22. When walking and stepping, the air bladder 25 deforms, squeezing the gas inside out. A non-woven fabric 26 is attached to the top of the sole 21. The insole 27 is attached, and the non-woven fabric 26 and the insole 27 both have second air holes 28 arranged in a leaf-like pattern. The air paths of the second air holes 28 and the air guide groove 22 are precisely aligned, and the diameters of the first air holes 24 and the second air holes 28 are matched in a stepped manner. The bottom of the sole 21 is fitted with an anti-slip pad 29, and the outside of the anti-slip pad 29 is fitted with a second one-way valve 210 to allow the air inside the sole 21 to be discharged to the outside and to prevent mud and water from entering. The outer circumference of the anti-slip pad 29 is integrally die-cast with a sealing mechanism 211. In addition, the air guide groove 22, the first air hole 24 and the second air hole 28 are all made in one piece using in-mold injection molding process, which can ensure that there is no air leakage during air venting.

[0023] The working principle of a side-mounted one-way exhaust shoe with a built-in air guide groove based on Embodiment 1 is as follows: When a user walks or exercises, their foot repeatedly steps on and lifts off the insole 27 and sole 21. When the foot presses down, the heat and moisture inside the shoe are compressed and enter the biomimetic leaf-shaped air channel 22 through the second air hole 28, which is precisely aligned with the air channel 22. At the same time, the air bladder 25 at the rear of the sole is compressed, and the internal gas is forced into the air channel 22. The air pressure inside the air channel 22 increases, and under the pressure difference, the first one-way valve 23 inside the air channel 22 is activated. The second one-way valve 210 on the outside of the anti-slip pad 29 will be opened, and the gas will be quickly discharged from the side of the shoe through the air duct 22, the first air hole 24, and the connection between the sole 21 and the anti-slip pad 29 by the compression of the air bag 25. When the foot is lifted, the space inside the shoe expands to form a negative pressure. The first one-way valve 23 and the second one-way valve 210 will automatically close under the action of the internal and external pressure difference to prevent external mud, water and dust from flowing back into the shoe, forming a one-way air circulation of "only out and no in" to keep the inside of the shoe dry.

[0024] Example 2:

[0025] Please see Figures 4-5This invention discloses a side-mounted one-way exhaust shoe with a built-in air guide groove. Compared to Embodiment 1, this embodiment further includes a sealing mechanism 211. The sealing mechanism 211 includes arc-shaped flexible expansion teeth 2111. The arc-shaped flexible expansion teeth 2111 are integrally die-cast on the outer circumference of the anti-slip pad 29. The teeth are evenly spaced along the outer circumference of the anti-slip pad 29 and are made of elastic modified plastic. During assembly, they are squeezed by the inner wall of the sole 21 and can be stretched outward to tightly hold the bottom of the sole 21, achieving bidirectional locking. A TPU waterproof layer is added to the outer side of the arc-shaped flexible expansion teeth 2111 using a plasma spraying process to form a dense waterproof membrane. The gap connecting the sole 21 and the anti-slip pad 29 is wrapped with a silicone sealing strip 2112, which, together with the TPU waterproof layer, forms a double waterproof barrier to prevent mud and water from entering through the gap. A circumferential annular rigid limiting frame 21 is installed on the anti-slip pad 29 and on the inner side of the arc-shaped flexible expansion teeth 2111. 13. The inner wall of the circumferential rigid limiting frame 2113 and the outer perimeter of the polyurethane foam block 2114 fit together perfectly, limiting the deformation of the polyurethane foam block 2114 to both sides and fixing its position. The polyurethane foam block 2114 is elastically fitted in the middle of the circumferential rigid limiting frame 2113, which can fill the small gap between the sole 21 and the anti-slip pad 29. The top support columns 2115 are neatly arranged inside the polyurethane foam block 2114. The two ends of the top support columns 2115 respectively support the high-elastic dense cushioning substrate layer 2116 and the wear-resistant and tear-resistant reinforcing fabric layer 2117, forming a rigid support. The high-elastic dense cushioning substrate layer 2116 is glued to the top of the polyurethane foam block 2114 with hot melt adhesive film to disperse the pressure of the sole 21 and prevent interface slippage. The wear-resistant and tear-resistant reinforcing fabric layer 2117 is glued to the bottom of the polyurethane foam block 2114 by hot pressing to improve the shear resistance and wear resistance.

[0026] In this embodiment: During the pressing and assembly process of the sole 21 and the anti-slip pad 29, the arc-shaped flexible expansion teeth 2111 on the outer periphery of the anti-slip pad 29 are squeezed by the inner wall of the sole 21, adaptively expanding outward and firmly holding the bottom of the sole 21, achieving bidirectional mechanical locking. At the same time, the outer TPU waterproof layer and the silicone sealing strip 2112 covering the seam together form a double water barrier to prevent mud and water from intruding from the seam. The foamed polyurethane block 2114 inside the circumferential ring rigid limiting frame 2113 is evenly compressed, using its own elasticity to fill the tiny gaps between the sole 21 and the anti-slip pad 29. The top support column 2115 prevents the foamed polyurethane block 2114 from being excessively flattened and failing. Then, the high-elastic dense cushioning substrate layer 2116 disperses the sole pressure. Finally, the wear-resistant and tear-resistant reinforced fabric layer 2117 improves the wear resistance and blocks the water seepage channel, achieving a long-term stable sealing effect.

[0027] This invention provides an improved side-mounted one-way ventilation shoe with a built-in air channel. An ventilation mechanism 2 is provided, where the foot's stomping and lifting motion compresses and releases the airbag 25. The pressure difference drives the first one-way valve 23 and the second one-way valve 210 to achieve one-way ventilation, enabling the directional expulsion of hot and moist air from the shoe while effectively blocking external mud, water, and dust, thus keeping the shoe dry. A sealing mechanism 211 is also provided, using multiple material layers to achieve a long-term, stable waterproof and dustproof seal between the sole 21 and the anti-slip pad 29, preventing water seepage, dust ingress, and adhesion failure.
