Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a breathable shoe sole combining a one-way valve and a Tesla valve. Background Technology

[0002] Shoes are a necessity of life, and as living standards improve, people's demands for shoe comfort also increase. Shoes generally fit snugly around the feet, making it difficult for air to circulate. During walking, stale air accumulates between the sole of the foot and the shoe sole, forming on the inner insole. If this stale air isn't expelled promptly, bacteria can easily grow, producing odors and making the shoes uncomfortable to wear. Therefore, various types of shoe soles with breathable properties have been developed.

[0003] Chinese patent announcement number CN 217958981U discloses a ventilated shoe sole. The sole includes an air chamber and an air inlet and outlet communicating with it. The air chamber is located at the corresponding heel position and partially protrudes from the bottom surface of the sole. The end of the air inlet facing away from the air chamber forms an air inlet hole communicating with the air inside the shoe, and the end of the air outlet facing away from the air chamber forms an air outlet hole communicating with the outside air. In this technical solution, because no one-way valve is added to the air inlet and outlet, when the user steps on the sole, air in the air chamber is often expelled into the air inlet. Furthermore, when the sole rebounds, outside air is drawn into the air chamber from the outlet, thus greatly reducing the effectiveness of air intake and exhaust. Utility Model Content

[0005] This utility model is achieved through the following technical solution: a breathable shoe sole combining a one-way valve and a Tesla valve, comprising a shoe sole body having a top surface and a bottom surface, the shoe sole body having an air cavity and an air inlet and an air outlet communicating with the air cavity, wherein the air inlet includes an air inlet channel and an air guide channel communicating with each other in sequence, the bottom surface of the shoe sole having an air inlet valve channel and an air outlet valve channel, the air inlet valve channel having an air inlet one-way valve that allows gas to flow toward the air cavity, the air outlet valve channel having an air outlet one-way valve that allows gas to flow toward the outside of the shoe sole body, one end of the air inlet valve channel communicating with the air inlet channel through an air inlet through hole, and the other end communicating with the air cavity, the air inlet through hole penetrating the top surface and the bottom surface of the shoe sole, one end of the air outlet valve channel communicating with the air outlet channel, and the other end communicating with the air cavity, the end of the air inlet channel opposite to the air guide channel forming multiple air inlet holes communicating with the air inside the shoe, and the end of the air outlet channel opposite to the air outlet valve channel forming an air outlet communicating with the outside air.

[0006] Preferably, the sole of this invention further includes a midsole, a bottom patch, and a side patch. The top surface of the sole is recessed downward to form an air intake channel groove and an air guide channel groove. When the midsole is tightly attached to the top surface of the sole, it forms an air intake channel and an air guide channel with the air intake channel groove and the air guide channel groove. The midsole has an air intake hole at the forefoot that corresponds to the position of the air intake channel.

[0007] Preferably, in this invention, the bottom surface of the shoe sole is recessed upward to form the air cavity groove, the air inlet valve channel groove, and the exhaust valve channel groove. When the bottom patch is tightly attached to the bottom surface of the shoe sole, the air cavity, the air inlet valve channel, and the exhaust valve channel groove are formed between the patch and the air cavity groove, the air inlet valve channel groove, and the exhaust valve channel groove.

[0008] Preferably, in this invention, one side of the sole is recessed inward to form an exhaust channel groove, and when the side patch is tightly attached to one side of the sole, the exhaust channel is formed between the patch and the exhaust channel groove.

[0009] Preferably, the lining of this invention has a circular protrusion that bulges towards the top surface of the sole at the position corresponding to the air cavity.

[0010] Preferably, the air cavity of this invention is located at the corresponding heel position and partially protrudes outward from the top surface of the sole.

[0011] Preferably, the air cavity of this invention is a circular bulge that gradually deepens from the outer edge to the middle and protrudes towards the top surface of the sole.

[0014] Preferably, the intake check valve and the exhaust check valve of this utility model are an integrated structure.

[0015] Preferably, the outer edge of the air cavity of this utility model is provided with an annular limiting platform, and the bottom patch facing the air cavity is provided with a circular boss that is adapted to the annular limiting platform. The circular boss and the air cavity groove together form the air cavity.

[0016] Preferably, the depth of the annular limiting platform on the bottom surface of the shoe sole is less than the depth of the air inlet channel groove and the air guide channel groove on the bottom surface of the shoe sole.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. This utility model has an intake valve and an exhaust valve respectively provided on the intake valve channel and exhaust valve channel of the shoe sole body. Through the combination of the intake valve, the exhaust valve and the Tesla valve groove, the airflow has a unidirectional flow during intake or exhaust, and is not affected by backflow. Thus, the airflow can only flow in one direction when intake or exhaust, which improves the overall exhaust effect of the shoe sole.

[0019] 2. The air chamber of this utility model is set at the point of force when the human body walks. When the air chamber is subjected to force, the airflow is concentrated in the exhaust valve channel, first transmitted to the exhaust channel by the exhaust one-way valve and then discharged through the exhaust hole. The air chamber plays the role of concentrating the airflow, making the exhaust effect better. Attached Figure Description

[0040] Reference Figures 1 to 6As shown, a breathable shoe sole combining a one-way valve and a Tesla valve includes a sole body 1 having a top surface 10 and a bottom surface 11. The sole body 1 has an air chamber 2 and an air inlet duct 3 and an air outlet duct 4 communicating with the air chamber 2. The air inlet duct 3 includes an air intake channel 5 and an air guide channel 6 that are sequentially connected. The bottom surface 11 of the sole has an air intake valve channel 110 and an air outlet valve channel 111. The air intake valve channel 110 has an air intake one-way valve 112 that allows gas to flow toward the air chamber, and the air outlet valve channel 111 has an air outlet valve that allows gas to flow toward the sole. The exhaust one-way valve 113 flows outside the body. One end of the air intake valve channel 110 is connected to the air intake channel 5 through the air intake hole 12, and the other end is connected to the air chamber 2. The air intake hole 12 penetrates the top surface 10 and the bottom surface 11 of the shoe sole. One end of the exhaust valve channel 111 is connected to the exhaust channel 4, and the other end is connected to the air chamber 2. The end of the air intake channel 5 away from the air guide channel 6 forms a plurality of air intake holes 50 that are connected to the air inside the shoe. The end of the exhaust channel 4 away from the exhaust valve channel 111 forms an exhaust hole 40 that is connected to the outside air.

[0041] In order to form an air intake channel 5, an air guide channel 6, an air chamber 2, an air intake valve channel 110, an exhaust valve channel 111, and an exhaust channel 4 on the sole, the sole also includes a midsole 7, a bottom patch 8, and a side patch 9.

[0042] Specifically, the top surface 10 of the sole is recessed downward to form an air intake channel groove and an air guide channel groove. When the midsole 7 is tightly attached to the top surface 10 of the sole, it forms an air intake channel 5 and an air guide channel 6 with the air intake channel groove and the air guide channel groove. The midsole 7 has an air intake hole 50 at the forefoot corresponding to the position of the air intake channel 5. The midsole 7 and the top surface 10 of the sole are bonded together by hot melting or adhesive. The midsole 7 completely covers the air intake channel groove and the air guide channel groove, or partially covers the air intake channel groove. When the midsole 7 partially covers the air intake channel groove, the reserved opening between the midsole 7 and the air intake channel groove is an air intake hole, so that the air inside the shoe can be connected with the air intake channel 5.

[0043] The sole surface 11 is recessed upwards to form an air chamber groove, an air inlet valve channel groove, and an exhaust valve channel groove. When the bottom patch 8 is tightly attached to the sole surface 11, it forms the air chamber 2, the air inlet valve channel 110, and the exhaust valve channel 111 between itself and the air chamber groove, the air inlet valve channel groove, and the exhaust valve channel groove. The bottom patch 8 is bonded to the sole surface 11 by hot melting or adhesive. The bottom patch 8 completely covers the air chamber groove, the air inlet valve channel groove, and the exhaust valve channel groove. The air chamber 2 is located at the corresponding heel position and partially protrudes outwards from the top surface 10 of the sole. When walking, the foot is subjected to force on the upper end of the air chamber 2, ensuring user comfort.

[0044] One side of the sole is recessed inward to form a ventilation channel groove. When the side patch 9 is tightly attached to one side of the sole, the ventilation channel 4 is formed between the side patch 9 and the ventilation channel groove. The side patch 9 is bonded to one side of the sole by heat fusion or adhesive. The side patch 9 completely covers or partially covers the ventilation channel groove. When the side patch 9 partially covers the ventilation channel groove, the reserved opening between the side patch 9 and the ventilation channel groove is a ventilation hole 40, so that the air inside the shoe can communicate with the air intake channel 5, and the airflow can be discharged from the ventilation hole 40 through the ventilation channel 4.

[0045] In addition, the lining 7 forms a circular protrusion 70 that protrudes towards the top surface 10 of the sole at the position of the air cavity 2, thereby increasing the space of the air cavity 2 and increasing the air flow inside the shoe.

[0046] According to one example of the present invention, the air guide channel 6 is a Tesla valve groove, and the direction from the air inlet to the air chamber is a low-resistance direction.

[0047] According to one example of the present invention, the exhaust channel 4 is a Tesla valve groove, and the direction from the exhaust hole to the air chamber is a high-resistance direction.

[0048] According to one example of this utility model, the sole body is made of MD material. MD belongs to EVA secondary high-pressure molding products and has the characteristics of light weight and good shock resistance. This material is a very good sole material. It can be made into a sole by pouring it into a mold. It is widely used in the production of running shoes, sneakers, etc. The shoes made from it are light, comfortable and elastic.

[0049] According to one example of this utility model, to prevent workers from reversing the flow direction of the intake one-way valve 112 and the exhaust one-way valve 113 during assembly, which could cause the air chamber of the shoe sole to burst and render the sole unusable, the intake one-way valve 112 and the exhaust one-way valve 113 of this utility model are an integral structure; of course, the intake one-way valve 112 and the exhaust one-way valve 113 can also be separate units.

[0050] When the intake check valve 112 and the exhaust check valve 113 are integrated into one piece, the flow direction of the intake check valve 112 and the exhaust check valve 113 is fixed during production, making the installation simpler for workers during assembly, which not only improves product quality but also reduces production costs.

[0051] To ensure that the air chamber 2 forms a sealed cavity, an annular limiting platform 20 is provided on the outer edge of the air chamber 2. The bottom surface patch 8 has a circular boss 80 that matches the annular limiting platform 20 on the side facing the air chamber 2. The circular boss 80 and the air chamber groove together form the air chamber 2. During production, the circular boss 80 and the annular limiting platform 20 are fixed together with adhesive.

[0052] When the circular boss 80 is assembled with the annular limiting platform 20, it can still ensure that the air chamber 2 can be connected to the air intake 3 and the exhaust 4 respectively. The depth of the annular limiting platform 20 on the bottom surface 11 of the shoe sole is less than the depth of the air intake channel groove and the air guide channel groove on the bottom surface 11 of the shoe sole, so that the circular boss 80 and the air intake channel groove and the air guide channel groove are both formed with gap holes 81 for airflow to pass through.

[0053] The working principle of this invention is as follows: When the wearer walks, the pressure exerted by the sole of the shoe when stepping down compresses the air chamber 1. Due to the combination of the Tesla valve and the one-way valve 112, the airflow does not enter the air intake duct 3 through the air intake hole 50. Therefore, the airflow is blown out through the exhaust duct 4 and the exhaust hole 5, and the airflow blown out of the exhaust hole 5 is discharged outside the shoe. Correspondingly, when the foot is lifted, the air chamber 1 returns to its original shape. Due to the combination of the Tesla valve and the one-way valve 113, it is difficult for outside air to enter through the exhaust duct 4. Therefore, the air inside the shoe is drawn into the air chamber 1 through the air intake hole 4 and the air intake duct 3. When the lifted foot touches the ground again, the air chamber 1 is compressed again, and the airflow is blown out through the exhaust duct 4 and the exhaust hole 5, and the airflow blown out of the exhaust hole 5 is discharged outside the shoe, realizing one-way air intake and one-way air exhaust, which are cyclical.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
