Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, and in particular to an active shoe sole ventilation system based on the coupling of aerodynamics and biomechanics. Background Technology

[0002] When you put on shoes, your feet and the inside of the shoes form a relatively sealed space. The air inside the shoes does not circulate well, which aggravates sweating and keeps your feet in a damp environment for a long time. This is especially true for people with sweaty feet, which can not only cause athlete's foot, but also easily lead to foot diseases.

[0003] To address the issue of poor ventilation inside shoes, existing shoes employ various solutions to achieve breathability.

[0004] Passive ventilation of the upper: Relies on the mesh fabric of the upper for ventilation, the ventilation efficiency is limited by the ambient wind speed, and it cannot effectively solve the problem of heat dissipation and sweating in the main sweat gland areas of the sole.

[0005] Vertical ventilation openings on the bottom: While vertical openings in the sole are intended to allow for foot ventilation, they have several drawbacks. They allow dust and mud to get in, cannot prevent liquids from the ground, and severely compromise cushioning and support by disrupting the continuity of the midsole material.

[0006] Built-in active ventilation: The system uses a micro fan for active ventilation and other energy-driven systems, which adds extra weight and has a limited battery life. The complex structure makes it cumbersome, increases the dynamic actions of consumers, and makes after-sales repair and replacement more difficult. Utility Model Content

[0007] To address the aforementioned issues, this invention provides an active sole ventilation system based on the coupling of aerodynamics and biomechanics. It utilizes the forward biomechanical kinetic energy generated during walking or running as the driving force, combined with the aerodynamic design of a biomimetic fighter jet air intake system. This system can efficiently and automatically solve the problem of foot ventilation without the need for external accessories, while also ensuring the protection and structural integrity of the sole.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an active sole ventilation system based on the coupling of aerodynamics and biomechanics, including a sole, the sole being provided with a biomimetic fighter jet air intake system, an acceleration channel, and an exhaust channel, wherein the biomimetic fighter jet air intake system includes several anti-wing-shaped air inlets and an air intake channel corresponding to and extending to the bottom surface of the sole, the anti-wing-shaped air inlets being located on the side of the sole and facing the front of the sole; the acceleration channel being located along the length direction of the sole on the bottom surface of the sole, the air intake channel being connected to the acceleration channel; the exhaust channel being located at the rear end of the bottom surface of the sole, the front end of the exhaust channel being connected to the end of the acceleration channel, the end of the exhaust channel extending to the surface of the heel of the sole to form an exhaust port communicating with the outside, and the exhaust channel being inclined upward relative to the horizontal plane.

[0009] Specifically, the wing-shaped air intake expands outward relative to the plane containing the side of the shoe sole.

[0010] Specifically, the reverse-wing type air intake includes an upper wing located at the upper end of the side of the sole and a lower wing located at the lower end of the side of the sole, wherein the front end of the upper wing has an upwardly extending upper sloping portion, and the front end of the lower wing has a downwardly extending lower sloping portion.

[0011] Specifically, the air intake is located on the inner side of the upper wing, and a guide channel is provided on the inner side of the lower wing, which extends along the lower slope of the lower wing to the air intake.

[0012] Specifically, the air intake is inclined toward the heel of the shoe sole.

[0013] Specifically, the width of the acceleration channel gradually decreases from the front end to the rear end, and the width of the exhaust channel gradually decreases from the front end to the rear end.

[0014] Specifically, the heel of the sole is inclined upward relative to the horizontal plane.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By setting up a biomimetic fighter jet air intake system that includes an anti-wing-shaped air inlet and an air intake duct, the relative movement direction between the foot and the air is matched to capture and guide airflow with maximum efficiency. At the same time, the sole surface is set with an acceleration channel connected to the air intake duct to accelerate and integrate the airflow entering from the biomimetic fighter jet air intake system. When flowing through the sole area, it forms a negative pressure adsorption effect, forming a unidirectional, high-speed airflow that actively draws in the hot and humid air from the sole, thereby greatly enhancing the heat exchange efficiency. Finally, the hot and humid air inside the sole is discharged from the exhaust port through the exhaust duct, converting the kinetic energy of movement into the power of ventilation, realizing self-driven heat dissipation without the need for external energy.

[0017] 2. The exhaust duct is inclined upward relative to the horizontal plane, which not only achieves efficient ventilation, but also solves the long-standing problems of dust and water entering the traditional bottom opening solution.

[0018] 3. All air ducts are integrated into the midsole structure, without disrupting its continuity like vertical perforations, thus fully preserving the cushioning, rebound, and support performance of the midsole. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-2 This embodiment discloses an active sole ventilation system based on the coupling of aerodynamics and biomechanics, including a sole 1. The sole 1 is equipped with a biomimetic fighter jet air intake system, an acceleration channel 2, and an exhaust channel 3. By applying the biomimetic fighter jet air intake system to the sole 1, the kinetic energy of human movement is converted into the power to drive the circulation of air inside the shoe. Combined with the acceleration channel and exhaust channel inside the sole 1, the aerodynamic effect is stimulated, achieving efficient passive ventilation of the foot microenvironment.

[0028] The biomimetic fighter jet air intake system includes several anti-wing type air intakes 4 and air intake ducts 5 that are connected to each anti-wing type air intake 4 and extend to the bottom of the shoe sole. The anti-wing type air intakes 4 are located on the side of the shoe sole and face the front of the shoe sole.

[0029] The anti-wing type air intake 4 includes an upper wing 41 located at the upper end of the side of the sole and a lower wing 42 located at the lower end of the side of the sole. The front end of the upper wing 41 has an upwardly extending upper slope 411, and the front end of the lower wing 42 has a downwardly extending lower slope 421, forming an anti-wing shaped air intake. By applying the air intake principle of fighter jets to the sole, the anti-wing type air intake 4 efficiently captures the airflow generated by the human body and the sole when walking forward, laying the foundation for the subsequent airflow and exhaust within the sole.

[0030] In order to capture more airflow generated by the human body and the sole 1 when walking forward, the wing-shaped air inlet 4 expands outward relative to the plane on the side of the sole to increase the area of ​​the wing-shaped air inlet 4 and capture more airflow into the sole 1.

[0031] Please see Figure 3 In a preferred embodiment, the air intake duct 5 is located inside the upper wing 41, and the lower wing 42 has a guide channel 422 on its inner side. The guide channel 422 extends along the lower slope 421 of the lower wing 42 to the air intake duct 5. During walking, the airflow generated by the relative movement of the foot and the air enters the air intake duct 5 directly from the inner side of the upper wing 41, and enters the air intake duct 5 along the guide channel 422 of the lower wing 42 from bottom to top and from outside to inside, ensuring that the maximum amount of airflow is captured and enters the sole. The path of the airflow from the guide channel 422 to the air intake duct 5 is as follows: Figure 3 As indicated by the black arrow.

[0032] To efficiently capture and guide airflow, the angle α of the upper wing 41's upper slope 411 can be selected from 15-45 degrees, preferably 30 degrees. Specifically, the angle α of the upper slope 411 tilting towards the sole is 30 degrees. Figure 4 As shown. This angle is optimized to match the relative movement of the feet and air during a step in the sagittal plane, in order to capture and guide airflow with maximum efficiency.

[0033] As a preferred implementation, in this embodiment, the wing-shaped air inlets 4 are simultaneously provided on both the outer and inner sides of the sole, and six wing-shaped air inlets 4 are provided on each side, distributed sequentially from the front of the sole side to the rear of the sole side; the wing-shaped air inlets 4 can also be provided on either the inner or outer side of the sole.

[0034] Please see Figure 2 The acceleration channel 2 is set on the bottom surface of the sole along the length of the sole, and the air intake 5 is connected to the acceleration channel 2. During the stepping process, the airflow captured by the anti-wing type air intake 4 enters the acceleration channel 2 through the air intake 5. When the gas flows through the acceleration channel 2, it actively draws in the hot and humid air from the sole of the foot so that it can be discharged outside the shoe later.

[0035] In this embodiment, two acceleration channels 2 are preferably provided, located on both sides of the bottom surface of the sole, corresponding to the wing-shaped air inlets 4 distributed on the inner and outer sides of the sole. The air inlet 5 of the wing-shaped air inlet 4 located on the inner side of the sole is connected to the acceleration channel 2 near the inner side of the sole; the air inlet 5 of the wing-shaped air inlet 4 located on the inner side of the sole is connected to the acceleration channel 2 near the inner side of the sole.

[0036] The relative airflow generated during the stepping process is captured by each anti-wing type air inlet 4 and enters the air intake duct 5, and then flows into the acceleration flow duct 2. The airflow entering the acceleration flow duct 2 is accelerated and integrated, which increases the flow velocity. When it flows through the foot area, it forms a negative pressure adsorption effect and actively draws in the hot and humid air from the foot.

[0037] As a preferred embodiment, the width of the acceleration channel 2 gradually decreases from the front end to the rear end. This structure can further increase the speed of airflow in the acceleration channel to obtain a greater negative pressure adsorption force, so as to draw more humid and hot air into the shoe.

[0038] Furthermore, in this embodiment, the air intake duct 5 is inclined towards the heel of the shoe sole. The airflow entering the air intake duct 5 has a dynamic tendency along the heel of the shoe sole. When it finally enters the acceleration channel, it generates a faster speed superposition, which makes the airflow faster in the acceleration channel 2 as a whole, forming a large negative pressure adsorption effect, actively drawing in more hot and humid air from the sole of the foot, and improving the exhaust effect.

[0039] Please see Figure 5 The exhaust duct 3 is located at the tail end of the bottom surface of the shoe sole. In this embodiment, two exhaust ducts 3 are provided, corresponding to the two acceleration channels 2. The front end of the exhaust duct 3 is connected to the end of the acceleration channel 2. The end of the exhaust duct 3 extends to the surface of the heel of the shoe sole to form an exhaust port 31 that communicates with the outside. The hot and humid air drawn in by the acceleration channel 2 is discharged from the exhaust port 31 through the exhaust duct 3. The exhaust duct 3 is inclined upward relative to the horizontal plane, which can effectively prevent external liquids from entering due to capillary action or splashing, and at the same time prevent most dust from falling directly in.

[0040] As a preferred implementation, the heel of the sole 1 is inclined upward relative to the horizontal plane. In this embodiment, the inclination angle is preferably 45 degrees. Together with the exhaust channel 3 which is originally set on the diagonal line, it forms a physical barrier to further prevent external impurities from falling into the exhaust port 31 and entering the interior of the sole. The upward guidance of the heel also helps the airflow to impact the heel more directly, improving the comfort of the body.

[0041] In a preferred implementation, the width of the exhaust duct 3 gradually decreases from the front end to the rear end. The airflow accelerated by the acceleration channel 2 enters the exhaust duct 3 and is further accelerated. The acceleration process creates a low-pressure zone inside the exhaust port 31, which not only helps to push the gas out, but also generates a backward "suction" to help to more actively and thoroughly "draw" the hot and humid air in the front of the shoe compartment to the rear and exhaust it. The system does not only "push the air with pressure", but also forms a powerful synergistic effect of "air intake in front and air extraction in rear" to exhaust the gas.

[0042] The complete principle of this embodiment is as follows:

[0043] The shoe made using this embodiment has an insole covering the bottom surface of the sole, and an air passage cavity is formed between the insole and the air intake 5, acceleration flow channel 2 and exhaust channel 3 on the bottom surface of the sole.

[0044] Air intake phase: When the wearer steps forward, the forward swing of the foot generates a relative wind speed, and the airflow is efficiently guided into the anti-wing type air intakes 4 on both sides;

[0045] Acceleration and heat exchange stage: The airflow converges and accelerates in the internal acceleration channel 2, forming a negative pressure zone, which powerfully draws in the humid and hot steam on the sole surface of the foot, completing efficient heat and mass exchange.

[0046] Exhaust stage: After heat exchange, the humid and hot air is driven by the subsequent airflow and flows towards and concentrates in the exhaust duct 3 at the rear.

[0047] Exhaust phase: Hot and humid air is forced out of the system through the upward-sloping exhaust duct 3 and exhaust port 31, completing a full "breathing" cycle.

[0048] Exclusivity: This cycle is strictly dependent on the "forward step" action. During the "pushing-back" phase of the gait cycle, the system is almost inactive due to the lack of effective relative wind speed, a characteristic that makes its energy utilization extremely efficient.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
