Description

Technical Field

[0001] This utility model discloses an anti-backflow drainage shoe sole, belonging to the field of footwear technology. Background Technology

[0002] In rainy areas of the south, frequent rainfall causes roads to remain damp or flooded for extended periods. When pedestrians walk, their shoes easily absorb a large amount of water due to rainwater penetration or splashes from the road. Traditional footwear products, limited by their closed structure and absorbent materials, cannot quickly drain water from the shoe cavity, resulting in the feet being in a damp environment for a long time. This not only reduces wearing comfort but may also cause foot health problems, seriously affecting the user experience.

[0003] To solve the problem of water accumulation inside shoes, existing technologies often involve setting drainage channels or perforated structures in the sole to allow water to drain out using gravity or walking pressure. However, such designs usually place the drainage holes directly on the ground surface of the sole, which can cause water to backflow into the sole if the water is deep. Therefore, a new solution is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a backflow-proof and drainage shoe sole to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a backflow prevention and drainage shoe sole, comprising a shoe sole body, the shoe sole body comprising a midsole, a drainage mechanism provided within the midsole, the drainage mechanism comprising a plurality of drainage holes, the drainage holes being vertically arranged and penetrating the midsole, a plurality of backflow prevention grooves provided at the top of the midsole, the drainage holes being disposed within the backflow prevention grooves, a one-way permeable cloth being provided within the backflow prevention grooves, the one-way permeable cloth covering the backflow prevention grooves.

[0006] Preferably, the unidirectional permeable fabric includes a unidirectional permeable membrane and a mesh base fabric.

[0007] Preferably, the drainage mechanism includes a drainage channel, which is disposed at the bottom of the midsole along the width direction of the midsole, and the drainage channel extends through both sides of the midsole. The drainage hole is connected to the drainage channel.

[0008] Preferably, the sole body includes an outsole, and the midsole is fitted and fixed to the outsole.

[0009] Preferably, the midsole is provided with a plurality of diffusion grooves, each of which is connected to all drainage grooves. The diffusion grooves are arranged along the length of the midsole, and drainage recesses corresponding to the positions of the diffusion grooves are provided on both sides of the outsole.

[0010] Preferably, the anti-backflow groove is located on the midsole at the position corresponding to the heel and the ball of the foot.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting an anti-backflow groove at the top of the midsole, placing the drainage hole in the groove and covering it with a one-way permeable fabric, the one-way permeable fabric allows water accumulated inside the shoe to drain outwards, while preventing external moisture from flowing back into the shoe through the drainage hole, effectively avoiding backflow and ensuring that the inside of the shoe remains dry.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They 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 the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] like Figure 1 , Figure 2 As shown, an anti-backflow drainage shoe sole includes a shoe sole body 1, the shoe sole body 1 includes a midsole 2, and a drainage mechanism is provided inside the midsole 2. The drainage mechanism includes a plurality of vertically arranged drainage holes 3 that penetrate the midsole 2. Through the drainage holes 3, water accumulated at the top of the midsole 2 can be guided to the bottom of the midsole 2, thereby preventing water from accumulating inside the shoe for a long time.

[0020] like Figure 2 As shown, the top of the midsole 2 is provided with several anti-backflow grooves 4, and the drainage holes 3 are located in the anti-backflow grooves 4. The anti-backflow grooves 4 are located on the midsole 2 at positions corresponding to the heel and the ball of the foot. The heel and the ball of the foot are the parts of the shoe most prone to water and sweat accumulation. Therefore, setting the drainage holes 3 at these two positions can improve the efficiency of drainage and moisture removal.

[0021] like Figure 3 As shown, a one-way permeable fabric 5 is installed inside the anti-backflow trough 4, covering the anti-backflow trough 4. The one-way permeable fabric 5 is designed for one-way drainage, allowing water above the shoe sole to pass through the one-way permeable fabric 5 into the anti-backflow trough 4 and drain out through the drain hole 3. However, water flowing back into the anti-backflow trough 4 from below the drain hole 3 cannot pass through the one-way permeable fabric 5 to enter the shoe. This avoids the backflow situation that can easily occur in areas with deep water where only the drain hole 3 is installed. The one-way permeable fabric 5 specifically includes... It includes a one-way permeable membrane 6 and a mesh base fabric 7. The one-way permeable membrane 6 is a membrane material with special directional transport function. Its principle is to precisely control the gradient difference between the surface micro-nano structure and chemical composition so that the liquid can only flow efficiently in a preset direction under the driving force of surface tension, capillary force and other forces. The reverse transport is effectively suppressed due to the significant structural resistance. When the one-way permeable membrane 6 is combined with the mesh base fabric 7, it can become a one-way permeable fabric 5 with higher strength, which can withstand the continuous pressure of the wearer.

[0022] like Figure 2 , Figure 4 As shown, the sole body 1 includes an outsole 9, and a midsole 2 is fitted and fixed to the outsole 9. The outsole 9 is a solid part, so the drainage holes 3 on the midsole 2 do not directly contact the ground, significantly reducing the risk of mud and sand clogging. The drainage mechanism also includes a drainage channel 8 connected to the drainage holes 3. The drainage channel 8 is set along the width direction of the midsole 2 at the bottom of the midsole 2 and runs through both sides of the midsole 2. Drainage recesses 10 are provided on both sides of the outsole 9, corresponding to the positions of the diffusion channels 11. When water flows into the bottom of the midsole 2 from the drainage holes 3, due to the obstruction of the outsole 9, the water will enter the drainage channel 8, and then flow along the drainage channel 8 to both sides of the sole, and finally... The water drains out through the openings of the drainage channels 8 on both sides of the sole. The drainage channels 8 can be set horizontally. In addition to natural diffusion, the water in the drainage channels 8 will also be shaken out when the wearer walks. The drainage channels 8 can also be set to slope downwards from the middle of the midsole 2 to both sides. In this case, even when stationary, the water will be continuously discharged due to its own weight and the slope of the drainage channels 8. Several diffusion channels 11 are also provided on the midsole 2. Each diffusion channel 11 is connected to all drainage channels 8. The diffusion channels 11 are set along the length of the midsole 2. Therefore, the diffusion channels 11 and the drainage channels 8 will form a drainage network, which will accelerate the discharge of water from the side under the pressure of walking.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
