Description
Technical Field
[0001] The utility model relates to a sole. Background Art
[0002] The Chinese patent document with the publication number CN218457450U discloses a one-way exhaust structure and a one-way exhaust sole thereof. The one-way exhaust structure is arranged on the sole, including an air chamber and an air inlet and an air outlet connected to the air chamber. The air inlet and the air outlet are both one-way air guide channels. The one-way air guide channel is a Tesla valve structure. The end of the air inlet away from the air chamber forms an air inlet hole connected to the air in the shoe, and the end of the air outlet away from the air chamber forms an air outlet hole connected to the outside air. The air inlet and the air outlet form a one-way air flow channel connected through the air inlet and the air outlet. The utility model discharges the air in the shoe during the wearer's daily walking process, and will not flow back to the air chamber, so as to achieve a repeated suction and discharge process, form an air flow cycle in the shoe, achieve a breathing effect of ventilating the shoe, improve the air flow in the shoe, can effectively discharge the heat and sweat in the shoe, keep the shoe dry and cool, enhance the air permeability, and improve the comfort of use.
[0003] However, in actual applications, the Tesla valve structure in the above scheme has a poor effect due to the small sole area and the limited length of the one-way air guide channel. When the user steps on the sole, the air in the air chamber is often discharged into the air inlet duct, and when the sole rebounds, the outside air will be sucked into the air chamber through the air outlet duct, resulting in poor air intake and exhaust effects. Utility Model Content
[0004] The utility model aims to provide a strong suction and exhaust breathable sole with strong suction and exhaust effects.

[0007] When the user steps on the sole body, the air in the air cavity will be squeezed toward the first one-way valve and the second one-way valve, and the air cannot pass through the first one-way valve, but the air can pass through the second one-way valve to be discharged from the sole body from the exhaust channel. When the user lifts his foot and the air cavity rebounds, the air cavity will inhale air under the action of atmospheric pressure, and the air in the intake channel will pass through the first one-way valve and enter the air cavity, while the air in the exhaust channel will be blocked by the second one-way valve and cannot enter the air cavity. The first one-way valve and the second one-way valve are matched with a closed ball and a conical section, so that the air can be instantly exhausted when the user steps on the sole. The closing ball in the first one-way valve is pushed toward the conical section for sealing. When the thrust of the gas disappears, the closing ball will slide down from the conical section due to gravity, thereby canceling the sealing effect. When the user lifts his foot and the air cavity rebounds, the closing ball in the second one-way valve can also be instantly sucked into the conical section for sealing. The response speed is faster and the sealing is stronger, which can achieve the effect of strong suction and discharge. The sole body can have a strong exhaust effect on the odor or hot air in the shoe, and can have a strong suction effect on the fresh air outside the shoe, thereby inhibiting the growth of bacteria and effectively preventing the occurrence of athlete's foot.
[0008] The valve body is provided with a blocking wall for preventing the closing ball from falling out, and an air vent is formed on the blocking wall. When the closing ball is pushed by the reverse airflow to open the gas channel, it will abut against the blocking wall to prevent the closing ball from falling out, and one-way passage of gas can be achieved through the air vent.
[0009] The blocking wall is formed with a plurality of vent holes arranged in a circumference. The plurality of vent holes can be provided to prevent the sealing balls from blocking the vent holes and thus preventing ventilation.

Dividing the valve body into the first shell and the second shell can facilitate the production of the product and the installation of the closing ball.
[0011] The first shell and the second shell are plug-fitted together, which can achieve a quick installation effect, and the plug-fitting does not require the use of additional fasteners to connect, saving costs.
[0012] The air cavity is arranged at the heel of the sole body, and the air inlet channel is connected with the top surface of the forefoot of the sole body, so that the air cavity can be more easily squeezed and deformed by the heel of the human body to inhale and exhaust air. The air inlet channel is connected with the top surface of the forefoot of the sole body, so that the air in the shoe can be well inhaled into the air cavity and discharged outside the shoe after the user wears the shoe.
[0013] The sole body comprises a main body, a patch and a middle lining, wherein an air cavity groove is formed at the heel of the bottom surface of the main body, an exhaust groove is formed on the bottom surface of the main body, one end of the exhaust groove is connected to the air cavity groove, and the other end extends to the side of the main body, and an air intake groove is formed on the top surface of the main body, one end of the exhaust groove is connected to the air cavity groove, and the other end extends to the forefoot of the main body. The patch is attached to the bottom surface of the main body to close the air cavity groove to form the air cavity and the exhaust groove to form the exhaust channel; the middle lining is attached to the top surface of the main body to close part of the air intake groove to form the air intake channel, and the middle lining does not close the air intake groove at the forefoot of the top surface of the main body, so that the air intake channel is connected with the top surface of the sole body, so that the air in the shoe can pass through the middle lining, enter the air cavity through the air intake channel, and finally be discharged through the exhaust channel. The three-layer design of the main body, the patch and the middle lining can facilitate the formation of the intake channel, the exhaust channel and the air cavity, and makes the installation of the first one-way valve and the second one-way valve simpler.
[0014] The air inlet groove includes a breathable section located at the forefoot of the top surface of the main body, and the breathable section constitutes a plurality of annular structures that are interconnected. The breathable section is arranged as an annular structure so that the contact area with the air in the shoe is larger and the air absorption efficiency is high.
[0015] The depth of the breathable section is 2-4 mm, and the width of the breathable section is 2-4 mm. If the depth and width of the breathable section are too small, the air inhalation efficiency will be too low. If the depth and width of the breathable section are too large, the user's feet will easily sink into the breathable section when wearing it, affecting the wearing experience.
[0016] The air inlet groove is provided with a first installation position for installing the first one-way valve near the air cavity groove, and the air exhaust groove is provided with a second installation position for installing the second one-way valve near the air cavity groove.
