Description

Technical Field

[0001] This invention relates to the technical field of insoles, and in particular to a breathable insole. Background Technology

[0002] Most insoles on the market are made of a single piece of foam sponge, with a small amount of leather and cotton. Cotton and leather have a sweat-absorbing effect, and the porous structure of foam sponge makes it breathable. However, because the insole is attached to the inside of the shoe, the air inside the shoe cannot circulate, which means the insole is not breathable. Over time, this can lead to heat buildup and sweating on the soles of the feet, as well as the growth of bacteria and odor. Summary of the Invention

[0003] To at least partially solve the aforementioned problems existing in the prior art, the present invention provides a breathable insole.

[0004] A breathable insole includes an insole body, the insole body comprising a first portion and a second portion, the first portion being provided with a flow guiding structure, and the second portion being provided with an air pumping structure. Both the flow guiding structure and the air pumping structure are in communication with the airflow on the insole surface. The flow guiding structure is provided with an air inlet and an air outlet, and the air pumping structure is provided with an air inlet and an air outlet. Both the air inlet and the air outlet are in communication with the external airflow, and the air outlet and the air inlet are in communication with the airflow. The air pumping structure is configured to exhaust air when pressurized and to draw in air when depressurized.

[0005] Optionally, the flow guiding structure includes a flow guiding groove that extends vertically through the first portion on the side near the sole of the shoe lining.

[0006] Optionally, the guide channel includes a first longitudinal channel and a first transverse channel. The first longitudinal channel is disposed in the middle region of the first segment and extends along the length of the insole body. The first longitudinal channel extends at least partially to the edge of the first segment. The first transverse channel is disposed on both sides of the middle region of the first segment and communicates with the adjacent first longitudinal channel. The first transverse channel extends from the first longitudinal channel to the edge of the first segment.

[0007] Optionally, the air outlet includes at least one of a first air outlet formed through the edge of the first portion along the extension direction of the guide groove and a second air outlet formed through the side of the first portion away from the sole surface of the shoe lining in a vertical direction.

[0008] Optionally, the second air outlet is formed at the intersection of the second longitudinal groove and at least part of the first transverse groove on the side of the insole body away from the insole lining, at the intersection of the second transverse groove and at least part of the first longitudinal groove on the side of the insole body away from the insole lining, and / or at the intersection of the annular groove and the first longitudinal groove and the first transverse groove on the side of the insole body away from the insole lining.

[0009] Optionally, the first longitudinal groove located in the middle of the first longitudinal groove extends from the air inlet end along the length direction of the insole body to the edge of the insole body, and the length of the several first longitudinal grooves on both sides of the first longitudinal grooves decreases sequentially from the inside to the outside.

[0010] Optionally, the air pumping structure includes an elastic skirt that surrounds the edge region of the second portion near the insole surface, the elastic skirt gradually converging from the insole body to the middle region of the insole body at one end away from the insole body;

[0011] The elastic skirt has an opening at the end away from the insole body to allow the air pump structure to communicate with the airflow on the insole surface.

[0012] Optionally, the second portion corresponds to the midfoot area and the heel area, and the air intake is located on the side of the second portion away from the insole surface, away from the arch of the foot.

[0013] Optionally, a one-way exhaust valve is provided at the air intake end;

[0014] The one-way exhaust valve includes a valve seat and a resilient valve plate. The valve seat has an air vent for connecting the flow guiding structure and the air pumping structure. The resilient valve plate is disposed in the air vent, with one end connected to the valve seat and the other end extending obliquely toward the flow guiding structure and covering the air vent.

[0015] Optionally, the flow guiding structure includes multiple flow guiding grooves, which penetrate vertically through the first portion near the sole of the shoe lining. The one-way exhaust valve includes multiple air vents and multiple elastic valve plates corresponding to each of the multiple air vents, with each air vent corresponding to one of the flow guiding grooves.

[0016] In a breathable insole of this invention, a flow-guiding structure and a pumping structure are configured, both of which are connected to the airflow on the insole surface. During walking, when the second section is raised, the pumping structure is not subjected to pressure, and negative pressure forces external air from the shoe opening into the pumping structure through the air inlet. When the second section hits the ground, the pumping structure is pressurized, and the internal air is discharged from the outlet and enters the flow-guiding structure through the air inlet. It then flows along the flow-guiding structure, carrying away the hot and humid air from the sole of the foot, and is discharged from the outlet. Finally, the air is discharged through the breathable material on the shoe surface. Because both the flow-guiding structure and the pumping structure are connected to the airflow on the insole surface, the air can effectively drive the airflow on the insole surface during circulation, thereby replacing the air on the entire insole surface. This solves the problem of heat accumulation, sweating, bacterial growth, and odor on the sole of the foot caused by poor air circulation on the insole surface. Furthermore, the entire insole structure has a relatively simple manufacturing process, allowing for large-scale production at a low cost. Attached Figure Description

[0023] The following reference Figures 1-6 This invention describes a breathable insole.

[0024] refer to Figures 1-6This invention provides a breathable insole, including an insole body. The insole body includes a first portion 1 and a second portion 2. The first portion 1 is provided with a flow guiding structure, and the second portion 2 is provided with a pumping structure. Both the flow guiding structure and the pumping structure are in communication with the airflow on the insole surface. The flow guiding structure is provided with an air inlet 13 and an air outlet 11, and the pumping structure is provided with an air inlet 21 and an air outlet. Both the air inlet 21 and the air outlet 11 are in communication with the external airflow, and the air outlet and the air inlet 13 are in communication with each other. The pumping structure is configured to exhaust air when pressurized and to draw in air when depressurized.

[0025] In a specific example, the first section 1 corresponds to the forefoot area, and the second section 2 corresponds to the midfoot area and the heel area.

[0026] During walking, when the second section 2 is lifted, the pumping structure is not under pressure. External air entering the shoe through the breathable material or opening can enter the pumping structure through the air inlet 21. When the second section 2 lands, the pumping structure is pressurized, and the internal air is discharged from the outlet, enters the guide structure through the inlet 13, flows along the guide structure, and is discharged from the outlet 11. Finally, it is discharged from the shoe body through the breathable material or opening. Because both the guide structure and the pumping structure are connected to the airflow on the insole, the air can effectively drive the airflow on the insole during circulation, thereby replacing the damp and smelly air on the entire insole and solving the problem of heat accumulation, sweating, bacterial growth, and odor caused by poor air circulation on the insole. Furthermore, the entire structure has a relatively simple manufacturing process, allowing for large-scale production at a low cost.

[0027] In some embodiments of the present invention, the flow guiding structure includes a flow guiding groove 12, one end of which is connected to the air pumping structure and the other end of which is connected to the air outlet 11. The flow guiding groove 12 extends vertically through the first portion 1 near the bottom surface of the shoe lining, so that the flow guiding groove 12 is in communication with the airflow on the bottom surface of the shoe lining.

[0028] In some embodiments of the present invention, the guide channel 12 includes a first longitudinal channel 121 and a first transverse channel 122. The first longitudinal channel 121 is disposed in the middle region of the first portion 1 and extends along the length direction of the insole body, and the first longitudinal channel 121 extends at least partially to the edge of the first portion 1. The first transverse channel 122 is disposed on both sides of the middle region of the first portion 1 and communicates with the adjacent first longitudinal channel 121, and the first transverse channel 122 extends from the first longitudinal channel 121 to the edge of the first portion 1.

[0029] By adopting a flow channel 12 that combines a first longitudinal groove 121 located in the middle region of the first section 1 with a first transverse groove 122 located on both sides of the middle region of the first section 1, the defects of the full longitudinal flow channel 12 layout, such as the existence of transverse coverage blind spots and the weakening of the structural continuity of the insole body in the transverse direction, are overcome. At the same time, the drawbacks of the transverse and longitudinal through-grid flow channel 12, such as air pressure dispersion and structural fragility, are avoided, thus meeting the dual requirements of airflow efficiency and structural reliability.

[0030] In some embodiments of the present invention, a plurality of first longitudinal grooves 121 located in the middle of the plurality of first longitudinal grooves 121 extend from the air inlet end 13 along the length direction of the insole body to the edge of the insole body, and the lengths of the plurality of first longitudinal grooves 121 on both sides of the plurality of first longitudinal grooves 121 are successively shortened from the inside to the outside.

[0031] In some embodiments of the present invention, the end of the guide channel 12 that is connected to the pumping structure is a conical structure and the opening on the side closer to the pumping structure is larger, which makes it easier to guide the gas discharged from the pumping structure into the guide structure.

[0032] In some embodiments of the present invention, the air outlet 11 includes at least one of a first air outlet 111 formed through the edge of the first portion 1 along the extension direction of the guide groove 12 and a second air outlet 112 formed through the side of the first portion 1 away from the sole surface of the shoe lining in a vertical direction.

[0033] Preferably, the air outlet 11 includes a first air outlet 111 and a second air outlet 112. By providing these two types of air outlets, on the one hand, airflow passes through the first air outlet 111 to the gap between the inner side of the shoe and the upper, maintaining a certain degree of ventilation even when the body weight is fully applied to the insole; on the other hand, airflow passes through the second air outlet 112 directly to the sole of the foot, quickly removing heat and moisture generated by the sole. These two functions complement each other and work together through multiple pathways, improving the reliability of the ventilation insole.

[0034] In some embodiments of the present invention, a second longitudinal groove 31, a second transverse groove 32, and an annular groove 33 are formed on the side of the insole body away from the insole lining. A second air vent 112 is formed at the intersection of the second longitudinal groove 31 and at least a portion of the first transverse groove 122, the intersection of the second transverse groove 32 and at least a portion of the first longitudinal groove 121, and / or the intersection of the annular groove 33 and the first longitudinal groove 121 and the first transverse groove 122. Furthermore, the side of the insole body away from the insole lining is divided into a matrix of spaced-apart blocks by the second longitudinal groove 31, the second transverse groove 32, and the annular groove 33. In a specific example, only one annular groove 33 is formed and located near the edge of the insole body. By forming the second longitudinal groove 31, the second transverse groove 32, and the annular groove 33 on the side of the insole body away from the insole lining, a second air vent 112 can be formed, and the friction between the sole of the foot and the insole contact surface can be increased to prevent slipping.

[0035] In some embodiments of the present invention, the air-pumping structure includes an elastic skirt 22 disposed around the edge region of the second portion 2 near the insole surface. The elastic skirt 22 gradually converges towards the center region of the insole body from the end away from the insole body, thereby forming an inverted airbag. An opening is provided at the end of the elastic skirt 22 away from the insole body to allow airflow communication between the air-pumping structure and the insole surface. The end of the elastic skirt 22 near the airflow guiding structure is the air outlet.

[0036] In some embodiments of the present invention, the air intake 21 is located on the side of the second portion 2 away from the insole surface, avoiding the arch of the foot. By positioning the air intake 21 away from the arch, when the pumping structure is pressurized, the heel can block the air intake 21, preventing insufficient gas flow to the air guide structure due to some gas escaping from the air intake 21, thus affecting ventilation. Simultaneously, positioning the air intake 21 on the side of the insole body away from the insole surface allows the pumping structure to draw in warm, humid air from the heel area along with the air during inhalation, and then expel it from the shoe. In a specific example, the air intake 21 comprises multiple air inlets, distributed along the length of the insole body and all positioned away from the arch of the foot.

[0037] In some embodiments of the present invention, a one-way exhaust valve is provided at the air inlet 13, so that gas can only flow from the pump structure to the guide structure, and the gas in the guide structure cannot flow back, which significantly improves the effective air exchange volume of the insole in a single stroke of the pump structure, and avoids the back-and-forth movement of hot and humid air under the feet inside the insole, which affects gas exchange.

[0038] In some embodiments of the present invention, the one-way exhaust valve includes a valve seat 41 and an elastic valve plate 42. The valve seat 41 has an air vent 43 for connecting the flow guiding structure and the air pumping structure. The elastic valve plate 42 is disposed in the air vent 43, with one end connected to the valve seat 41 and the other end extending obliquely towards the flow guiding structure and covering the air vent 43.

[0039] During operation, when gas flows from the pump structure to the guide structure, the elastic valve plate 42 tilts upwards towards the guide structure under gas pressure, opening the vent 43 and allowing smooth gas flow. When the gas flows in the opposite direction, the elastic valve plate 42, under the action of gas pressure and its own elastic restoring force, covers the vent 43 again to prevent backflow, thus achieving unidirectional gas flow.

[0040] In some embodiments of the present invention, multiple guide channels 12 are provided, and the one-way exhaust valve includes multiple vents 43 and multiple elastic valve plates 42. Each vent 43 corresponds to a guide channel 12, and an elastic valve plate 42 is provided in each vent 43.

[0041] Of course, the one-way exhaust valve may also include multiple valve seats 41, each valve seat 41 having an air vent 43, each air vent 43 corresponding to a guide groove 12, and each air vent 43 having an elastic valve plate 42.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
