Description

Technical Field

[0001] The present invention relates to the field of footwear, and in particular to a self-breathing and ventilating shoe. Specifically, the present invention proposes a shoe with active breathing and ventilation function, which uses walking and stepping as the power, and inhales fresh air into the shoe and exhales the dirty air in the shoe to the outside of the shoe through the cycle of inhaling and exhaling air of the self-breathing and ventilating air cushion while walking. It can effectively eliminate heat, sweat, moisture and odor in the shoe, and because of the buffering and boosting effect of the air cushion, the shoe has the overall effect of being dry, comfortable, non-suffocating, non-heaty, non-sweaty, shock-absorbing, boosting, hygienic and healthy. It can be widely used in industries and fields where wrapping and protection are needed, such as fire rescue, military and police, exploration, labor protection, outdoor and other industries. Background Art

[0002] With the development of science and technology and society, 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 shoes for work and life is becoming increasingly strong, especially for shoes for special industries. While ensuring functionality, comfort and health are increasingly valued. For example, in fire rescue, military police, exploration, labor protection, outdoor and other industries, footwear that requires tight wrapping and protection has a wide range of closed spaces inside the shoes, and the gas cannot be circulated to the outside, resulting in suffocation, heat, sweat, humidity, odor, etc. In severe cases, it causes sanitary and health problems such as rot, athlete's foot, and rot, causing discomfort and trouble to workers in the above industries.

[0003] In tropical and subtropical areas with high temperature, heat and humidity, the above problems are particularly serious, causing long-term and widespread foot diseases; people in these areas have no choice but to use slippers, but in some places and industries, it is obviously indecent, so there is an urgent need for a pair of shoes that can provide protection, ventilation, dryness, comfort, hygiene and health. In summary, we look forward to a solution to improve and solve the above problems in the above industries and regions. Summary of the invention

[0004] In view of the above problems and needs, the present invention provides a self-breathing ventilation shoe.

[0005] The technical solution proposed by the present invention is as follows:

[0006] The invention discloses an autonomous breathing and ventilation shoe. The shoe is designed with an autonomous breathing and ventilation air cushion with autonomous breathing and ventilation functions. The shoe is provided with an inlet and outlet valve, which connects the inside and outside of the shoe and is arranged between the sole and the upper to realize the breathing and ventilation functions.

[0007] The self-breathing and ventilation shoes are composed of a rubber outsole that wraps the air cushion, a puncture-proof insole that protects the air cushion, a self-breathing and ventilation air cushion, a well-ventilated insole, and an upper that can replenish air, from bottom to top, including:

[0008] Air outlet valve mounting holes are symmetrically arranged at the rear center positions on both sides of the outer sole, corresponding to the positions of the air outlet valve mounting holes of the air cushion body.

[0009] The stab-proof insole is made of a flexible stab-proof material and is fitted to the inside of the outsole.

[0010] The air cushion body is made of elastic material, and the air cushion body and the sealing film are airtightly fitted to form the air cushion body.

[0011] The air cushion adopts an integrated double breathing chamber structure, and the middle rear part is divided into two front and rear breathing chambers by a Z-shaped partition wall. They correspond to the front and rear soles of the feet respectively and work independently.

[0012] On the top walls of the two breathing chambers of the air cushion, there are respectively provided with a ring-shaped air intake hole group and an air intake valve diaphragm mounting hole, and an air intake valve diaphragm is installed. The air intake hole group and the air intake valve diaphragm together constitute a one-way air intake valve, which is connected to the space inside the shoe; the air intake valve is closed when the air cushion breathing chamber is under positive pressure and opens when the pressure is negative.

[0013] The air outlet valve mounting holes of the two chambers are symmetrically arranged at the rear center of the side wall of the second breathing chamber of the air cushion, and correspond to the positions of the air outlet valve mounting holes of the outer bottom.

[0014] The air outlet valve has a one-way function and a flange structure. It runs through the air outlet valve mounting holes installed on the outer bottom and the air cushion. It opens when the breathing chamber is under positive pressure and closes when the breathing chamber is under negative pressure.

[0015] The top wall of the second breathing chamber of the air cushion is provided with columnar support columns with different diameters and uniform distribution to support and maintain the shape of the air cushion.

[0016] The front side of the air cushion is respectively provided with radial ventilation grooves with two breathing cavity air inlet hole groups as the center, and the two groups of grooves are communicated.

[0017] The reverse side of the insole is provided with radial and annular ventilation grooves interwoven with each other, and a plurality of holes are arranged in the grooves, which are connected with the space inside the shoe upwards and with the air inlet of the air cushion downwards.

[0018] Air replenishment holes are provided at the junction of the toes and soles of the shoes and at the arches to facilitate the entry of external air into the shoes when there is negative pressure inside the shoes. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 As shown, a pair of self-breathing and ventilation shoes is composed of a rubber outer sole 1, a puncture-proof inner sole 2, a self-breathing and ventilation air cushion 3, an air outlet control valve 23 and an air replenishment hole 5, which cooperate with each other to achieve the function.

[0027] Figure 3 The main body of the autonomous breathing ventilation air cushion is made of elastic material and is divided into a front breathing chamber 7 and a rear breathing chamber 8 by a Z-shaped partition wall 6. The gas in the two chambers can only enter through the air inlet group 9 and 10 when the pressure is negative, and through the air outlet valve 23 installed in the air outlet valve installation holes 11 and 12 when the pressure is positive. Figure 5 )discharge.

[0028] Figure 3 The two breathing chambers 7 and 8 are provided with the inlet valve diaphragm mounting holes 13 and 14 on the top wall. Figure 4 The air intake valve diaphragm 15 and 16 and the air intake hole groups 9 and 10 together constitute the air intake valve of the front and rear breathing chambers 7 and 8. When the breathing chambers 7 and 8 are under negative pressure, the air intake valve diaphragms 15 and 16 open, and the air in the shoe is sucked into the breathing chamber through the air intake hole groups 9 and 10.

[0029] The air inlet groups 9 and 10 of the two breathing chambers 7 and 8 are connected Figure 6 The ventilation grooves 17 and 18 are passed through Figure 7 The ventilation grooves 19 and 20 and the groove hole groups 21 and 22 are communicated with the space inside the shoe.

[0030] Figure 3 The breathing chamber 7 and 8 have the outlet valve mounting holes 11, 12 and Figure 2 The outer bottom air outlet valve installation hole corresponds to the Figure 5 The outlet valve 23 is installed through Figure 3 The outlet valve mounting holes 11, 12 and Figure 2 The outsole air outlet valve mounting hole 4. When the breathing chambers 7 and 8 are under positive pressure, the air outlet valves 23 at 11 and 12 are opened, and the gas is discharged outside the shoe.

[0031] The spontaneous breathing ventilation shoe breathing work cycle is as follows:

[0032] When walking naturally, the heel of the shoe touches the ground first after taking a step. Figure 3 The rear breathing chamber 8 is compressed to form a positive pressure, which pushes the inlet valve diaphragm 16 of the rear breathing chamber 8 to close the inlet port group 10, and the pressure simultaneously pushes open the outlet valve 23 installed at 12 ( Figure 5 ), release the pressure, the gas in the cavity is discharged until the internal and external pressures are balanced, and the outlet valve 23 at 12 ( Figure 5 )closure.

[0033] As the body's center of gravity moves forward, the heels are lifted. Figure 3 As shown, the pressure in the breathing chamber 8 is released, and the support column group 31 in the chamber returns to its original state under the action of the elastic material, and the volume of the chamber 8 increases, forming a negative pressure. At this time, the outlet valve 23 ( Figure 5 ) is closed, and the air in the shoe passes through the air inlet hole group 10, pushes open the air inlet valve diaphragm 16, and is sucked into the rear breathing chamber 8 until the pressure is balanced. The air inlet valve diaphragm 16 is tightly attached to and closes the air inlet hole group 10, completing the suction of air in the shoe and waiting to enter the next working cycle.

[0034] As the heel is lifted and the sole of the foot touches the ground, the front breathing cavity 7 corresponding to the forefoot is compressed, forming a positive pressure. The pressure pushes the inlet valve diaphragm 15 of the front breathing cavity 7 to close the inlet hole group 9, and the pressure simultaneously pushes open the outlet valve 23 installed at the outlet valve installation hole 11 ( Figure 5 ), release the pressure, the gas in the cavity is discharged until the internal and external pressures are balanced, and the outlet valve 23 at 11 ( Figure 5 )closure.

[0035] As the sole of the foot is lifted, the pressure in the front breathing chamber 7 is released, and the support column group 30 in the chamber returns to its original state under the action of the elastic material. The volume of the chamber 7 increases, forming a negative pressure. At this time, the outlet valve 23 ( Figure 5 ) is closed, the air in the shoe pushes open the air inlet valve diaphragm 15 and enters the front breathing chamber 7 through the air inlet hole group 9 until the pressure is balanced. The air inlet valve diaphragm 15 is attached to and closes the front cavity air inlet hole group 9, completing the inhalation of air in the shoe and waiting to enter the next working cycle.

[0036] As walking progresses, the heel touches the ground again, repeating the working cycle of

[00032]

[00033]

[00034]

[00035] over and over again. During the working cycle, the air in the shoe is sucked away by the breathing chamber, forming a negative pressure inside the shoe, and the fresh air from the outside will pass through Figure 1 The air enters the shoe through the air replenishment hole 5, the gap between the shoe mouth and the ankle, and the gap between the upper fabric; and then enters the shoe through Figure 7 The ventilation grooves 19, 20, the groove hole groups 21, 22, Figure 6The air cushion front grooves 17 and 18 reach the air inlet groups 9 and 10.

[0037] With every step you take, the four breathing cavities in your feet complete a breathing and ventilation cycle in turn, taking away heat, sweat, moisture and odor between inhaled and exhaled air; the air cushion itself and its elastic material can achieve shock absorption, cushioning and power assistance functions.

[0038] Example 1

[0039] like Figure 3 The columnar support column group 30 shown in the figure is evenly selected from the center. Figure 3 24, appropriately increased and evenly distributed, increases the volume of the breathing cavity, thereby enhancing the breathing efficiency, can be compressed and deformed by a smaller force, and has no effect on the compression rate.

[0040] like Figure 3 The columnar support column group 31 shown in the figure, the support column in the rear breathing chamber 8 is appropriately thickened as shown in the figure. Figure 3 25, and connected at half height as Figure 3 26, increases strength, increases elasticity, enhances the cushioning effect when the heel strikes the ground, and enhances the power when lifting off.

[0041] like Figure 3 A group of supporting columns arranged in a ring shape, having a small diameter and a short height are arranged around the ring intake valve diaphragm 15 as shown in FIG. Figure 3 27, protecting the intake valve diaphragm from deformation of the air cushion body.

[0042] like Figure 3 The air inlet groups 9 and 10 of the top wall of the breathing chamber are arranged at the toes, the soles of the feet and the arch of the foot. These two places are prone to sweating and are the main gas storage spaces in the shoes.

[0043] like Figure 3 The transverse partition wall 6 shown is in a Z shape, with two breathing chamber parts interlaced with each other, and the air outlet valve mounting holes 11, 12 of the front and rear breathing chambers are symmetrically arranged on the two side walls of the air cushion.

[0044] like Figure 6 The front of the autonomous breathing ventilation air cushion shown is provided with radial ventilation grooves 17 and 18 in the shape of a cross, with two air inlet groups as the center, and connected front to back to enhance air circulation and flow rate.

[0045] The various technical solutions in this embodiment are all for improving the breathing and ventilation effects and the aesthetic effects, but are not limited to the above solutions.

[0046] Example 2

[0047] like Figure 7The reverse side of the insole is provided with grooves corresponding to the grooves on the front side of the air cushion, and is provided with several circles of annular grooves 28 and 29 connecting the radial grooves 19 and 20.

[0048] The technical solution in this embodiment is to make the air in the shoe flow smoothly when it passes to the autonomous breathing air cushion, thereby enhancing the circulation and flow rate.

[0049] Example 3

[0050] like Figure 5 The air outlet control valve 23 shown adopts a flange structure.

[0051] In this embodiment, if Figure 1 The outlet control valve 23 shown is installed for normal breathing function and will be Figure 5 The outlet control valve 23 shown is installed in reverse. Figure 5 The air outlet valve 32 shown can cancel the breathing ventilation function. At this moment, the breathing cavity gas cannot be discharged, i.e., there is no breathing ventilation effect, and only the air cushion function is available.

[0052] Example 4

[0053] like Figure 1 A plurality of air supply holes 5 are provided on the upper surface as shown.

[0054] In this embodiment, when there is negative pressure inside the shoe, fresh air passes through the air holes 5 and passes over the soles of the feet, the junctions of the toes, the soles of the feet and other parts that are prone to sweating, taking away sweat and heat, and bringing a better breathing experience.

[0055] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific embodiments, which are merely illustrative and not restrictive. Those skilled in the art can obtain other corresponding changes and deformations, or other forms, such as a single air cushion, a single air outlet valve, etc., based on the principles and structures disclosed by the present invention, and these changes and deformations and other forms are within the protection scope of the present invention without departing from the purpose of the present invention and the scope of protection of the claims.
