Description

Technical Field

[0001] This invention relates to the field of footwear air cushions, and more particularly to a self-breathing air cushion. Specifically, this invention proposes an air cushion with active breathing function, powered by walking and treading, which, through the breathing action of the self-breathing air cushion, draws fresh air into the shoe and expels air out of the shoe, effectively removing sweat, moisture, odor, and heat from inside the shoe, combined with the cushioning effect of the air cushion. Overall, it provides dryness, comfort, shock absorption, hygiene, and health benefits, and can be widely used in footwear requiring protective covering and in industrial footwear, such as firefighting, rescue, military and police work, exploration, outdoor activities, and marching. It ensures comfort and health while providing protection. Background Technology

[0002] With the development of science and technology and the economy, people's requirements for quality of life are increasing day by day. Footwear products are inseparable from our work and life, and the desire for high-quality work and life shoes is becoming stronger and stronger. Especially for shoes used in special industries, while ensuring functionality, comfort and health are receiving more and more attention. For example, shoes used in fire rescue, military and police, exploration, and outdoor activities, which require tight protection, often suffer from a closed space inside the shoe, which prevents air from circulating. This leads to stuffiness, heat, sweat, dampness, and odor inside the shoe. In severe cases, it can cause hygiene and health problems such as rotting, athlete's foot, and decay, causing discomfort and trouble for workers in these industries.

[0003] In tropical and subtropical regions with high temperatures, humidity, and heat, these problems are particularly severe, causing widespread foot ailments. People are often forced to wear slippers, which can be considered unsightly in certain places or at certain times. Therefore, a solution is needed to improve and resolve these issues in the aforementioned industries and regions. Summary of the Invention

[0004] To address the aforementioned problems and needs, this invention proposes a self-breathing air cushion for shoes, which is placed between the sole and the upper to facilitate breathing and ventilation, thereby achieving the functions of heat dissipation, sweat dissipation, moisture dissipation, and odor dissipation.

[0005] The technical solution proposed in this invention is as follows:

[0006] This invention proposes a self-breathing air cushion for shoes. The air cushion employs an integrated dual-cavity structure, covering the entire foot, with each cavity corresponding to the heel and sole, operating independently. Made of elastic, airtight material, the air cushion features a one-way inlet valve connecting to the inside of the shoe and a one-way outlet valve connecting to the outside. During natural walking, the breathing chambers of the self-breathing air cushion experience pressure as the heel and sole strike the ground sequentially. This pressure compresses the corresponding front and rear breathing chambers, creating positive pressure, and the gas inside is expelled through the outlet valve. When the foot is lifted, the pressure is released, the elastic material returns to its shape, creating negative pressure, drawing fresh air into the shoe through the inlet valve. With each heel and sole striking the ground, the front and rear breathing chambers complete one breathing action, alternating in a cycle to achieve self-breathing. Combined with the inherent elasticity of the air cushion, this achieves functions such as sweat wicking, moisture wicking, odor removal, heat dissipation, shock absorption, and foot support, ultimately resulting in dry, comfortable, hygienic, and healthy feet.

[0007] The present invention proposes a self-breathing air cushion for shoes. The main body of the air cushion is made of elastic material and is composed of an air cushion body and a sealing film that are airtightly bonded together, wherein:

[0008] The invention proposes a self-breathing air cushion for shoes with an integrated dual-breathing chamber structure. The middle rear part is divided into two chambers by a Z-shaped partition wall, which can work independently for the front and rear of the foot.

[0009] The invention proposes a self-breathing air cushion for shoes. The top walls of the two breathing chambers are respectively provided with a ring-shaped air inlet hole group and an air inlet valve diaphragm mounting hole, and an air inlet valve diaphragm is installed. The air inlet hole group and the air inlet valve diaphragm together constitute a one-way air inlet valve. The air inlet valve is closed when the breathing chamber is under positive pressure and opened when it is under negative pressure.

[0010] The shoe-type self-breathing air cushion proposed in this invention has two symmetrically located air outlet valve mounting holes for the two chambers on the side walls of the main body.

[0011] The shoe-type self-breathing air cushion proposed in this invention has one-way air valves installed in the air outlet valve mounting holes on the side walls of the two chambers. These valves open when the breathing chamber is under positive pressure and close when it is under negative pressure.

[0012] The main body of the self-breathing air cushion for shoes proposed in this invention has several support columns of different diameters that are evenly distributed on the top wall of the two breathing chambers to support and maintain the shape of the air cushion.

[0013] The front of the shoe-mounted self-breathing air cushion proposed in this invention has radial ventilation grooves centered on two annularly arranged air inlets, with the two sets of grooves communicating with each other.

[0014] The footwear self-breathing air cushion proposed in this invention has an annular columnar air inlet valve diaphragm protective column around the air inlet hole group of the front breathing chamber. Attached Figure Description

[0015] Figure 1 A schematic diagram of the internal structure of the self-breathing air cushion for shoes is shown.

[0016] Figure 2 A schematic diagram of the air inlet valve diaphragm for a shoe's self-breathing air cushion is shown.

[0017] Figure 3 A schematic diagram of the air outlet valve of the shoe's self-breathing air cushion is shown.

[0018] Figure 4 A schematic diagram of the radial ventilation grooves on the front of the shoe's self-breathing air cushion is shown. Detailed Implementation

[0019] like Figure 1 The shoe's self-breathing air cushion is made of elastic material, and the main body is airtightly bonded to the sealing membrane to form the whole air cushion. The main body is divided into two independent chambers 2 and 3 by a Z-shaped partition 1. The gas in the chamber can only enter through the air inlet group 4 and 5 of the front and rear breathing chambers when the pressure is negative, and through the air outlet valve 12 installed in the air outlet valve mounting holes 6 and 7 when the pressure is positive. Figure 3 )discharge.

[0020] The main body of the shoe's self-breathing air cushion has two breathing chambers on its top walls, each with a ring-shaped arrangement of air inlets 4 and 5 and air inlet valve diaphragm mounting holes 10 and 11, and is equipped with... Figure 2 The air intake diaphragm. The air intake diaphragms 8 and 9, together with the air intake hole group 4 and 5, form the air intake valves for the front and rear breathing chambers. When the breathing chamber is under negative pressure, the air inside the shoe is drawn into the breathing chamber through the air intake valve diaphragms 8 and 9 and the air intake hole group 4 and 5.

[0021] The shoe's self-breathing air cushion has two breathing chamber exhaust valve mounting holes 6 and 7. Figure 3 When the breathing chamber is under positive pressure, the pressure inside the chamber pushes open the vent valve 12, expelling the air outside the shoe.

[0022] The work cycle using an independent breathing air cushion is as follows:

[0023] Taking a single foot as an example, when you take a step, the heel hits the ground first, compressing the posterior respiratory chamber 3 corresponding to the heel, creating positive pressure, which propels the foot forward. Figure 1 The intake valve diaphragm 9 is pressed tightly against and seals the intake port assembly 5, while simultaneously pushing open the exhaust valve 12 installed at 7. Figure 3 The pressure is released, the gas is discharged, and the internal and external pressures are balanced until the gas outlet valve 12 is closed.

[0024] When the heel is lifted, the pressure in the rear breathing chamber 3 is released. Under the action of the elastic material support column, it returns to its original state, the volume of the breathing chamber increases, forming a negative pressure. The exhaust valve 12 at point 7 closes, and air pushes the intake valve diaphragm 9 and is drawn into the breathing chamber 3 through the intake port group 5 until the pressure is balanced. The intake valve diaphragm 9 then adheres tightly to and closes the intake port group 5, completing the working cycle and waiting to enter another working cycle.

[0025] As walking continues, the heel lifts and the forefoot lands, compressing the anterior breathing chamber 2 corresponding to the forefoot. Positive pressure is created within the breathing chamber, which pushes the intake valve diaphragm 8 to adhere tightly and seal the intake port assembly 4. Simultaneously, the pressure pushes open the exhaust valve 12 installed at the exhaust valve mounting hole 6. Figure 3 ), release pressure, gas is discharged until pressure is balanced, vent valve 12 at point 6 ( Figure 3 )closure.

[0026] As the foot is lifted, the pressure in the anterior breathing chamber 2 is released. Under the action of the elastic support column, it returns to its original state, the chamber volume increases, and negative pressure is formed. The exhaust valve 12 installed at position 6 ( Figure 3 When the air intake valve diaphragm 8 is closed, air pushes open the air intake valve diaphragm 8 and enters the breathing chamber 2 through the air intake port group 4 until the pressure is balanced. Then the air intake valve diaphragm 8 closes the air intake port group 4, completing the working cycle and waiting to enter the next working cycle.

[0027] As walking continues, the heels touch the ground again, and the work cycle of

[00023]

[00024]

[00025]

[00026] is repeated, alternating in sequence. With each step, the four breathing chambers of both feet complete a breathing process, carrying away sweat, moisture, odor, and heat; the elastic material of the self-breathing air cushion and the air cushion body work together to achieve shock absorption, cushioning, and assistance functions.

[0028] Example 1

[0029] Figure 1 The shoe features a self-breathing air cushion support column, with several centrally located columns as shown. Figure 1 The 14 is appropriately increased and evenly distributed to increase the volume of the breathing cavity, thereby enhancing breathing efficiency. It can be compressed and deformed by a small force, without affecting the compression ratio.

[0030] Figure 1 The columnar support column shown should be appropriately thickened within the posterior respiratory chamber, as indicated. Figure 1 15, and connected at half height as Figure 1 The 16th grade increases strength and elasticity, enhances the cushioning effect when the heel lands, and provides additional support when lifting off the ground.

[0031] Figure 1The front breathing chamber shown has a set of ring-shaped support columns 19 with smaller diameter and slightly shorter height around the inlet valve diaphragm 8 to protect the inlet valve diaphragm from deformation of the air cushion.

[0032] Figure 1 The transverse partition 1 shown is Z-shaped, with two breathing chambers partially intersecting each other, and the air outlets 6 and 7 of the front and rear breathing chambers are symmetrically arranged on both sides of the Z-shaped partition.

[0033] Figure 4 The shoe's self-breathing air cushion shown has radial ventilation grooves 17 and 18 centered on a ring-shaped group of air inlets, which enhances airflow and volume.

[0034] Figure 1 The shoe's self-breathing air cushion shown is covered inside the air cushion by an airtight sealing film.

[0035] The technical solutions in the embodiments can be implemented in other ways.

[0036] Example 2

[0037] Figure 2 The air inlet valves of the front and rear breathing chambers of the shoe's self-breathing air cushion shown are composed of annularly arranged air inlet holes 4 and 5 on the top wall of the breathing chamber of the air cushion body and air inlet valve diaphragms 8 and 9.

[0038] Figure 3 The air valve 12 of the shoe's self-breathing air cushion shown adopts a columnar flange structure to facilitate secure clamping and assembly onto the air cushion body.

[0039] Figure 4 The shoe's self-breathing air cushion shown has two sets of interconnected radial grooves 17 and 18 on the front, which are connected to the air inlet group 4 and 5 to increase airway patency and increase gas flow.
