[0023] 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.
[0024] like Figures 1-5 As shown, this embodiment provides a waterproof one-way ventilation sole. The sole contains an air chamber 1 and an air passage connected to the air chamber 1. The air passage includes an air inlet 2 and an air outlet 3. A protruding bump 4 is provided on the outer side of the sole, and the bump 4 is a hollow elastic structure that, together with the sole, forms a ventilation chamber connected to the air outlet 3. A flat opening 41 is provided on the outer end face of the bump 4 as a ventilation port. The air chamber 1, air inlet 2, and air outlet 3 are formed as follows:
[0025] 1. The upper surface of the sole is recessed inward to form an air chamber groove, an air inlet groove, and an air outlet groove. When a bonding piece is tightly attached to the upper surface of the sole, it forms an air chamber 1, an air inlet 2, and an air outlet 3 with the air chamber groove, the air inlet groove, and the air outlet groove. The sole is made of TPU foam particles. TPU foam particles have low density, good wear resistance, low hardness, good resilience, high tensile strength, and good tear resistance, which makes the sole lightweight, elastic, and cushioning, and increases the shock absorption performance of the sole. The bonding piece is bonded to the upper surface of the sole by hot melt or adhesive.
[0026] 2、the lower surface of the shoe sole is inwardly recessed to form an air chamber groove, an air inlet groove and an air outlet groove, and a close-fitting sheet is tightly fitted to the lower surface of the shoe sole to form an air chamber 1, an air inlet 2 and an air outlet 3 between the air chamber groove, the air inlet groove and the air outlet groove, and the material and the fitting method of the close-fitting sheet are the same as those of method 1;
[0027] 3、the shoe sole 1 includes a midsole 101 and an outsole 102, the midsole 101 is made of TPU foamed particles, the TPU foamed particles have small density, good wear resistance, low hardness, good resilience, high tensile strength and good tear resistance, so that the overall quality of the shoe sole is light, elastic and has good cushioning performance, and the outsole 102 is made of rubber material and has good wear resistance, the lower surface of the midsole 101 is inwardly recessed to form an air chamber groove, an air inlet groove and an air outlet groove, and the upper surface of the outsole 102 is tightly and hermetically bonded to the lower surface of the midsole 101 to form an air chamber 1, an air inlet 2 and an air outlet 3 between the air chamber groove, the air inlet groove and the air outlet groove;
[0028] 4、the shoe sole 1 includes a midsole 101 and an outsole 102, the upper surface of the midsole 101 is downwardly recessed to form an air chamber groove and an air inlet groove, a close-fitting sheet is tightly fitted to the upper surface of the midsole to form an air chamber 1 and an air inlet 2 between the air chamber groove and the air inlet groove, the lower surface of the midsole 101 is upwardly recessed to form an air outlet groove, and the upper surface of the outsole 102 is tightly and hermetically bonded to the lower surface of the midsole 101 to form an air outlet 3 between the air outlet groove.
[0029] This embodiment is further described by taking method 3 as an example:
[0030] The air chamber 1 is arranged at a corresponding heel position and has a circular top structure gradually deepening inward from the outer edge to the middle part, the air inlet 2 and the air outlet are both one-way air flow channels, one end of the air inlet 2 away from the air chamber 1 forms an air inlet hole 21 in communication with the air in the shoe, one end of the air outlet 3 away from the air chamber 1 is in communication with the exhaust cavity, the air inlet 2 is arranged at a corresponding position of the instep, the air outlet 3 extends along the air chamber groove to the rear part of the midsole 101 corresponding to the edge of the heel, the outsole 102 extends a heel piece corresponding to the heel, the convex bump 4 is arranged on the heel piece and integrally formed with the outsole 102, the convex bump 4 has an inclined surface or a curved surface, the inclination of the inclined surface or the curvature of the curved surface gradually decreases in the outward direction of the shoe from the air outlet, for example, the shape of the convex bump 4 can be triangular, trapezoidal, conical frustum or umbrella-shaped, when fluid pressure is applied to the exhaust cavity, the opening 41 is opened to communicate with the outside to exhaust the gas in the shoe, and when the fluid pressure disappears, the opening 41 remains closed under the action of its own elasticity and / or external pressure to prevent water and / or air from entering the shoe.
[0031] As Figure 5As shown, the air intake duct 2 is a Tesla valve structure. The direction from the air intake port 21 to the air chamber 1 is a low-resistance direction. The air intake port 21 is located at the end of the air intake duct 2. There can be one or multiple ports. The air outlet can be a normal flow channel or a Tesla valve structure. The direction from the exhaust chamber to the air chamber 1 is a high-resistance direction.
[0032] When the wearer walks, the pressure from the sole of the shoe compresses the air chamber 1. Due to the unidirectional nature of Tesla, the airflow cannot easily enter the air intake duct 2 through the air inlet 21. Therefore, it enters the exhaust chamber through the air outlet 3. The convex 4 overcomes its own elasticity, and the opening 41 opens, allowing the airflow to be blown out of the shoe. Subsequently, the air pressure in the exhaust chamber disappears, and the convex 4 remains closed under its own elasticity and / or external pressure. When the foot is lifted, the air chamber 1 returns to its original shape, and the opening 41 closes. It is difficult for water and air from the outside to enter through the air outlet 3. Therefore, the air inside the shoe is drawn into the air chamber 1 through the air inlet 21 and the air intake duct 2. When the lifted foot touches the ground again, it compresses the air chamber 1 again, and the airflow is blown out of the shoe through the air outlet 3 and the opening 41. This achieves unidirectional air intake and unidirectional air exhaust, which are cyclical.
[0033] like Figure 6 As shown, the air intake duct 2 is equipped with a one-way valve 22 that allows air to enter in one direction towards the air chamber 1, and the air outlet duct 3 can be a normal flow channel or it can be equipped with a one-way valve 31 that allows air to exit in one direction towards the exhaust chamber.
[0034] When the wearer walks, the pressure from the sole of the shoe compresses the air chamber 1. Due to the one-way nature of the one-way valve 22, the airflow cannot easily enter the air intake duct 2 through the air inlet 21. Therefore, it enters the exhaust chamber through the air outlet 3. The convex 4 overcomes its own elasticity, and the opening 41 opens, allowing the airflow to be blown out of the shoe. Subsequently, the air pressure in the exhaust chamber disappears, and the convex 4 remains closed under its own elasticity and / or external pressure. When the foot is lifted, the air chamber 1 returns to its original shape, and the opening 41 closes. It is difficult for water and air from the outside to enter through the air outlet 3. Therefore, the air inside the shoe is drawn into the air chamber 1 through the air inlet 21 and the air intake duct 2. When the lifted foot touches the ground again, it compresses the air chamber 1 again, and the airflow is blown out of the shoe through the air outlet 3 and the opening 41. This achieves one-way air intake and one-way air exhaust, which are cyclical.
[0035] The utility model discloses a shoe sole is provided with air storehouse and air passage, and is provided with a flat mouth -shaped opening on the convex envelope and forms the exhaust port, makes the shoe through the process of daily walking of wearer, reaches the cyclic repetition of air suction and release process, forms the airflow flow circulation in the shoe, improves the air flow in the shoe, effectively discharges the hot air and sweat in the shoe, makes the shoe keep dry and cool, enhances the air permeability, promotes the use comfort, and the convex envelope has elasticity, keeps closed state under the action of self -elastic force and / or external pressure, and the water and air of outside cannot open the closed opening and enter the shoe, strengthens the waterproof performance of shoe, is applicable to various weather and environment, especially in rainy day or wading, provides better waterproof protection.
[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
