TECHNICAL FIELD

[0001] The present invention pertains to the technical field of light textile and light industry, and more particularly relates to a breathing insole.BACKGROUND

[0002] Shoes are commonly used wearable items in people's daily lives. Traditional sports shoes generally improve the breathability inside the shoe by changing the shoe upper materials. However, since perspiration of the insole of the foot mainly occurs at the bottom of the foot, and as the human body sweats during exercise-especially the feet, which contain numerous sweat glands and are prone to sweating-if the insole lacks breathability, sweat will accumulate inside the shoe, causing dampness of the feet and generating unpleasant odors. When the feet remain in a damp environment for an extended period, the skin of the feet easily softens, thereby increasing friction and the risk of injury. A breathable insole can timely discharge moisture, keep the feet dry, and reduce discomfort and friction-related damage.

[0003] At present, shoes generally adopt breathable upper materials, such as mesh fabric or canvas. These materials possess good air circulation properties. However, the effect of improving breathability by changing shoe upper materials is limited, and the scope of application is relatively narrow, making it difficult to achieve widespread use.

[0004] In order to solve the above-described problems, recently, patent KR100576381B1 proposes, and looking at its technical configuration according to Figures 2-6, shoe S of the present invention is composed of an insole 100 in which an insole pad 10, a shock absorber 50, and a sweat absorption pad 30 are combined. A sweat absorption pad 30 is attached to the upper surface of the insole pad 10 as shown in FIG. 2. Ventilation holes 12 are connected to the bottom surface of the insole pad 10 to maintain a communication state, and distribution grooves 14 are formed between the communication holes 12 as shown in FIG. 4.The distribution groove 14 is connected to the shock absorber receiving groove 16 formed on the bottom surface of the insole pad 10 on which the heel is seated. Therefore, the air supplied from the shock absorber accommodating groove 16 passes through the distribution groove 14 and is supplied to the ventilation hole 12. However, how to achieve the smooth circulation of air is crucial for improving breathability.

[0005] Therefore, providing a breathing insole with excellent breathability, long service life, safety and reliability, and a comfortable foot feel is a problem that technicians in this field urgently need to solve.SUMMARY

[0006] In order to overcome the shortcomings of the prior art, the objective of the present invention is to provide a breathing insole with a simple structure and excellent breathability as specified in appended independent claim 1. Additional embodiments of the invention are disclosed in the dependent claims.

[0007] To achieve the above objective, the present invention provides the following technical solution, which mainly comprises:

[0008] A breathing insole, which sequentially comprises, from top to bottom, an upper insole, a breathing layer, and a lower insole, wherein the upper insole, the breathing layer, and the lower insole are bonded together by adhesive.

[0009] The upper insole: an insole portion adopts a shape close to that of a full insole, and the front end of the insole portion adopts a shovel-shaped structure. The bottom of the upper insole is bonded to the breathing layer.

[0010] The breathing layer: the breathing layer is provided with an air inlet hole, an air chamber, a ventilation hole, a breathing hole, a breathing channel, and an air inlet channel. The heel portion of the breathing layer is provided with an air chamber. The bottom of the air chamber is provided with an air inlet hole. The toe-front region of the insole portion of the breathing layer is provided with a breathing channel. The breathing channel is provided with breathing holes. An arch portion of the breathing layer is provided with ventilation holes. The air inlet holes, the ventilation holes, and the breathing holes are interconnected through the breathing channel.

[0011] The lower insole: the top of the lower insole is bonded to the breathing layer.

[0012] Preferably, the air inlet channel comprises a first air inlet channel and a second air inlet channel. The breathing channel is connected with the air inlet hole through the first air inlet channel. The ventilation hole is connected with the first air inlet channel through the second air inlet channel. The breathing channel is provided with breathing holes, and the breathing holes are located in the toe-front region of the breathing layer.

[0013] The air chamber adopts a frustum structure, and the diameter of the top of the air chamber is greater than the diameter of the bottom of the air chamber.

[0014] Preferably, the breathing channel is formed in the forefoot toe flexion area of the breathing layer. Preferably, the ventilation holes are formed in the arch region of the breathing layer.

[0015] Preferably, the air inlet holes, the ventilation holes, and the breathing holes all penetrate through the breathing layer. Preferably, the arch region of the upper insole is provided with ventilation holes.

[0016] Preferably, the upper insole adopts torsion-resistant materials such as TPU, PA nylon, or carbon fiber plates. The breathing layer adopts high-resilience materials such as EVA, ETPU popcorn, PU, or supercritical materials. The lower insole adopts wear-resistant materials such as wear-resistant rubber or CPU.

[0017] From the above technical solution it can be seen that, compared with the prior art, the breathing layer of the present invention achieves overall breathability of the insole through structures such as the air inlet holes, the air chamber, the ventilation holes, the breathing holes, and the breathing channel. It effectively discharges moisture and heat from inside the shoe, keeping the feet dry and comfortable. The breathing layer, made of a high-resilience material, can effectively absorb the impact force during walking and reduce the burden on the feet. The upper insole, made of a torsion-resistant material, provides stable support, ensuring comfort and safety during wearing. The lower insole, made of wear-resistant material, effectively prolongs the service life of the insole, and even under harsh walking conditions can maintain good grip and wear resistance.BRIEF DESCRIPTION OF DRAWINGS

[0020] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the embodiments. It is apparent that the described embodiments are merely part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort shall fall within the scope of protection of the present invention.Embodiment

[0021] A breathing insole, as shown in Figures 1 to 3, sequentially comprises, from top to bottom, an upper insole 1, a breathing layer 2, and a lower insole 3. The upper insole 1, the breathing layer 2, and the lower insole 3 are connected by hot-melt bonding or adhesive bonding.

[0022] In order to further optimize the above solution, an insole portion of the upper insole 1 adopts a shape close to that of a full insole, and the front end of the insole portion adopts a shovel-shaped structure. The bottom of the upper insole 1 is bonded to the breathing layer 2.

[0023] In order to further optimize the above solution, the breathing layer 2 is provided with an air inlet hole 4, an air chamber 5, a ventilation hole 6, a breathing hole 7, a breathing channel 8, and an air inlet channel. The heel portion of the breathing layer 2 is provided with the air chamber 5. The bottom of the air chamber 5 is provided with the air inlet hole 4. The toe-front region of the insole portion of the breathing layer 2 is provided with the breathing channel 8. The breathing channel 8 is provided with the breathing hole 7. An arch portion of the breathing layer 2 is provided with the ventilation hole 6. The air inlet hole 4, the ventilation hole 6, and the breathing hole 7 are interconnected through the breathing channel 8.

[0024] In order to further optimize the above solution, the top of the lower insole 3 is bonded to the breathing layer 2.

[0025] In order to further optimize the above solution, the air inlet channel comprises a first air inlet channel 9 and a second air inlet channel 10. The breathing channel 8 is connected with the air inlet hole 4 through the first air inlet channel 9. The ventilation hole 6 is connected with the first air inlet channel 9 through the second air inlet channel 10. The breathing channel 8 is provided with the breathing hole 7, the breathing hole 7 is located in the toe-front region of the breathing layer 2. The breathing hole 7 promotes the exchange of air between the inside and outside of the shoe. A gap is maintained between the breathing hole 7 and the toes, which not only ensures sufficient support and fitting comfort, but also prevents the ventilation hole from being directly pressed by the foot. Under both daily exercise and non-exercise conditions, the breathing hole 7 is not affected in performing air exchange, thereby keeping the feet cool and enhancing both exercise endurance and wearing comfort.

[0026] In order to further optimize the above solution, the air chamber 5 adopts a frustum structure, wherein the diameter of the top of the air chamber 5 is larger than the diameter of the bottom of the air chamber 5. The air chamber 5 utilizes the principle of airflow counteraction to realize the functions of air intake and exhaust, while also facilitating the smooth circulation of air.

[0027] In order to further optimize the above solution, the breathing channel 8 is formed in the forefoot toe flexion area of the breathing layer 2, which conforms to ergonomic principles and helps to improve comfort and efficiency during walking.

[0028] In order to further optimize the above solution, the ventilation hole 6 is formed in the arch region of the breathing layer 2, which conforms to ergonomic principles and helps to improve comfort and efficiency during walking.

[0029] In order to further optimize the above solution, the air inlet hole 4, the ventilation hole 6, and the breathing hole 7 all penetrate through the breathing layer 2.

[0030] In order to further optimize the above solution, the upper insole 1 is provided with ventilation holes 11 in the arch region. The ventilation holes 11 are located in the arch region in accordance with ergonomic principles. When the foot is wearing the shoe, a gap exists between the ventilation holes 11 and the foot, which not only ensures sufficient support and fitting comfort, but also prevents the ventilation holes from being directly pressed by the foot. This does not affect the air exchange function of the ventilation holes 11, thereby helping to maintain a dry environment inside the shoe and reducing foot dampness and stuffiness. Whether during high-intensity exercise or in daily non-exercise conditions such as walking or standing, the ventilation holes 11 remain unobstructed and will not be blocked due to foot movement or pressure changes, thus ensuring continuous and efficient gas exchange within the insole.

[0031] In order to further optimize the above solution, the upper insole 1 adopts torsion-resistant materials such as TPU, PA nylon, or carbon fiber plates. The breathing layer 2 adopts high-resilience materials such as EVA, ETPU popcorn, PU, or supercritical materials. The lower insole 3 adopts wear-resistant materials such as wear-resistant rubber or CPU.

[0032] Working principle: External air can enter the breathing channel 8 through the breathing holes 7, and then enter the air chamber 5 from the air inlet hole 4 via the first air inlet channel. When the heel portion steps on and compresses the air chamber 5, gas exchange occurs. The air chamber 5 is connected to the breathing channel 8 through the air inlet channel, thereby forming a complete air circulation path, effectively realizing the ventilation and air exchange of the insole, and maintaining freshness and comfort of the shoe interior environment. The high-resilience material adopted in the breathing layer 2 can effectively absorb the impact force generated during walking, reduce the burden on the foot, prevent sports injuries, and improve the wearing comfort.

[0033] In this specification, the respective embodiments are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts among the various embodiments may be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method section.
