Description
Technical Field
[0001] This utility model relates to the field of shoe insole technology, specifically to a multifunctional shoe insole. Background Technology
[0002] Currently available insoles offer limited functionality, falling short in terms of breathability, cushioning, and slip resistance. When walking or exercising, feet tend to sweat. Ordinary insoles, with their poor breathability, leave feet in a hot and humid environment for extended periods, fostering bacterial growth, unpleasant odors, and potentially causing foot skin problems. Furthermore, existing insoles fail to provide adequate cushioning, failing to effectively absorb impact on the heel during walking, which can damage foot joints and bones over time. The lack of slip resistance also increases instability during walking or exercise, impacting comfort and safety.
[0003] Existing technology (CN 207322821 U) discloses a breathable insole with shock absorption function. This patent achieves good breathability and shock absorption by setting up gas channels, air bladders, and shock-absorbing blocks. However, its anti-slip function relies solely on the structural design of the shock-absorbing blocks and is not specifically optimized for anti-slip performance. Furthermore, the gas channels and air bladders of this insole are located inside the insole, making its manufacturing process complex.
[0004] In addition, while the gas channels and shock-absorbing structure of the insole can improve breathability and cushioning, it does not mention how to effectively prevent the insole from sliding inside the shoe, thus its anti-slip performance is insufficient.
[0005] The prior art (CN204742821U) discloses an insole. This patent improves the warmth and shock absorption of the insole through a double-layer design of elastic pad and fleece pad. However, its breathability depends only on a small number of ventilation holes on the elastic pad, which cannot achieve efficient air circulation.
[0006] Therefore, it is essential to design a multifunctional insole that is both breathable and provides good cushioning while being safe and slip-resistant. Utility Model Content
[0007] To address the aforementioned issues, a multifunctional insole is provided that combines breathability, shock absorption, slip resistance, and lightweight properties.
[0008] This utility model is achieved in the following manner: A multifunctional insole includes an insole body, which includes a forefoot area, an arch area, and a heel area. A semi-bubble is provided in the center of the heel area. A drainage channel is provided on the lower surface of the insole body. A ventilation hole penetrating the insole body is provided in the drainage channel. The semi-bubble is connected to the drainage channel.
[0009] Preferably, the bottom of the semi-bladder is provided with a protrusion.
[0010] Preferably, the guide channel includes a longitudinal guide channel arranged along the length of the insole body. The longitudinal guide channel gradually narrows from the forefoot area to the arch area. The longitudinal guide channel includes a first longitudinal guide channel, a second longitudinal guide channel, and a third longitudinal guide channel. The first longitudinal guide channel is connected to the semi-bubble. The second longitudinal guide channel extends to the heel area and surrounds the semi-bubble in the heel area. One end of the third longitudinal guide channel is connected to the outside of the insole. The forefoot area is provided with a transverse flow channel, which is set along the width direction of the insole body and connected to the outside of the insole. The transverse flow channel is connected to the longitudinal flow channel. The heel area is provided with a first radial flow channel, which is set along the circumference of the semi-bladder and extends radially outward. The first radial flow channel intersects with and is connected to the second longitudinal flow channel.
[0011] Preferably, the vent is located at the intersection of the transverse guide groove and the longitudinal guide groove, or in the transverse guide groove, or in the longitudinal guide groove, or in the area outside the guide groove. The vent is located at the intersection of the first radial guide groove and the second longitudinal guide groove.
[0012] Preferably, the ventilation holes include a first ventilation hole in the forefoot area, a second ventilation hole in the arch area, and a third ventilation hole in the heel area.
[0013] Preferably, a semi-cyst is provided at the center of the forefoot area.
[0014] Preferably, the guide channel includes a latitudinal guide channel arranged around the two semi-bladders, the latitudinal guide channel narrowing in the arch area, wherein the latitudinal guide channel near the outer periphery of the insole communicates with the outside of the insole at the boundary between the arch area and the heel area, the guide channel also includes a fourth longitudinal guide channel connecting the two semi-bladders, and the forefoot area and the heel area are each provided with a second radial guide channel, each second radial guide channel extending outward along the radial direction of the semi-bladder, the second radial guide channel communicating with the latitudinal guide channel.
[0015] Preferably, the ventilation holes are located in the lateral guide groove and the fourth longitudinal guide groove at the arch of the foot, or at the intersection of the second radial guide groove and the lateral guide groove, or in the second radial guide groove, or in the area outside the guide groove. The ventilation holes include a fourth ventilation hole located in the arch area, and a fifth ventilation hole located in the forefoot area and the heel area.
[0016] Preferably, the semi-cyst has a height of 10mm, a length of 45mm, and a width of 25mm.
[0017] Preferably, the width of the guide groove is 2mm and the depth is 4mm, the diameter of the first, third or fifth ventilation holes in the forefoot and heel areas is 2mm, and the diameter of the second or fourth ventilation hole in the arch area is 2.5mm.
[0018] Compared to existing technologies, this invention greatly improves the breathability of the insole by forming an air circulation system through ventilation holes and guide channels, as well as the air suction effect of the semi-bubble in the heel and forefoot areas. The semi-bubble design in the heel and forefoot areas effectively cushions the impact force on the heel during walking, providing excellent shock absorption performance. Several guide channels are set at the bottom of the insole to improve its anti-slip performance. The use of semi-bubble to create air suction eliminates the need for additional suction devices, and the semi-bubble is molded in one piece from polyurethane high-foam material and is integrally molded with the insole body. The design of multiple guide channels and semi-bubble makes the insole lighter. Attached Figure Description

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0028] like Figures 1-7 As shown, a multifunctional insole includes an insole body 1, which includes a forefoot area 2, an arch area 3, and a heel area 4. The center of the heel area 4 is provided with a semi-sac 5, which is specifically a structure formed by the upper surface of the insole protruding and the lower surface concave in the central area of the heel area 4. The lower surface of the insole body 1 is provided with a guide groove 6, and the guide groove is provided with a ventilation hole 7 that penetrates the insole body 1. The semi-bladder 5 is connected to the guide groove 6. The heel area 4 of the insole adopts a semi-bladder design. The insole is placed in the shoe cavity, and the semi-bladder and the sole form a closed air cavity. The guide groove 6 and the sole form a closed gas flow channel. During walking, the heel exerts pressure on the insole, the semi-bladder is squeezed, and the internal air is squeezed out. The air is squeezed into the guide groove, and the gas flows through the guide groove to the arch area, forefoot area and edge of the insole body. The guide groove is provided with a ventilation hole, and the gas enters between the insole and the foot through the ventilation hole. When the heel is lifted, the semi-bladder returns to its original shape, forming a negative pressure, which draws in the outside air. This cycle makes the air in the shoe cavity flow, further enhancing the breathability. Meanwhile, the semi-foam structure possesses excellent elasticity, effectively cushioning the impact on the heel and resisting deformation, providing a durable and stable shock absorption effect. The semi-foam structure is molded in one piece from high-density polyurethane foam material and is integrally formed with the insole body, eliminating the need for additional suction devices and reducing the insole's weight. Furthermore, the airflow channels are located at the bottom of the insole, simplifying its manufacturing process. The airflow channels at the bottom of the insole not only guide airflow but also improve the insole's anti-slip performance.
[0029] Furthermore, such as Figure 3 As shown, the bottom lower surface of the semi-bladder 5 is provided with a protrusion 8. The protrusion extends along the length of the semi-bladder. When the semi-bladder is squeezed and the heel is lifted, the protrusion 8 can make the semi-bladder bounce up quickly.
[0030] Furthermore, such as Figure 2 As shown, the guide channel 6 includes a longitudinal guide channel 61 arranged along the length direction of the insole body 1. The longitudinal guide channel 61 gradually narrows from the forefoot area 2 to the arch area 3. The longitudinal guide channel 61 includes a first longitudinal guide channel 611, a second longitudinal guide channel 612, and a third longitudinal guide channel 613. The first longitudinal guide channel 611 is connected to the semi-bubble 5. The second longitudinal guide channel 612 extends to the heel area and surrounds the semi-bubble 5 of the heel area 4. One end of the third longitudinal guide channel 613 is connected to the outside of the insole. The longitudinal guide channel 61 allows the air squeezed out of the semi-bubble to be quickly guided to the arch area and the forefoot area.
[0031] The forefoot area is provided with a transverse airflow channel 62, which is set along the width direction of the insole body and connected to the outside of the insole. The transverse airflow channel 62 intersects with the longitudinal airflow channel 61 and is connected at the intersection point, further guiding the airflow to various positions of the forefoot.
[0032] The heel area 4 is provided with a radial guide groove 63. The first radial guide groove 63 is arranged along the circumference of the semi-bladder 5 and extends outward along the radial direction of the semi-bladder in a radial arrangement. The first radial guide groove 63 is connected to the semi-bladder 5. The first radial guide groove 63 intersects and is connected with the second longitudinal guide groove 612, so as to quickly guide the air squeezed out of the semi-bladder to the heel area.
[0033] Furthermore, the vent 7 is located at the intersection of the transverse guide groove 62 and the longitudinal guide groove 61, or is located within the transverse guide groove 62, or within the longitudinal guide groove 61, or in an area outside the guide groove 6. The vent 7 is located at the intersection of the first radial guide groove 63 and the second longitudinal guide groove 612.
[0034] Furthermore, the ventilation holes 7 include a first ventilation hole 71 in the forefoot area 2, a second ventilation hole 72 in the arch area 3, and a third ventilation hole 73 in the heel area 4. The diameters of the first and third ventilation holes are smaller than that of the second ventilation hole. The diameters of the first and third ventilation holes are 2mm, while the diameter of the second ventilation hole is 2.5mm. The small-diameter ventilation holes in the forefoot and heel areas, which bear the brunt of the impact, ensure breathability while maximizing the integrity and strength of the material, preventing the insole from deforming, collapsing, or breaking under high stress. For the arch area, which sweats heavily, the large-diameter ventilation holes effectively form the main channel for air circulation, significantly improving the heat dissipation and moisture removal efficiency in this area, keeping the soles of the feet dry, and fundamentally solving the problem of stuffiness.
[0035] Furthermore, the semi-bladder 5 has a height of 10mm, a length of 45mm, and a width of 25mm. The airflow channel 6 has a width of 2mm and a depth of 4mm to ensure smooth airflow. When the foot comes into contact with the insole, air can enter through the ventilation holes and circulate within the airflow channel, carrying away the heat and moisture generated by the foot, thus achieving air circulation under the feet and keeping them dry.
[0036] See Figures 6-7 To increase the breathability of the insole, a semi-sac 5 is also provided in the center of the forefoot area 2.
[0037] Furthermore, the guide channel 6 includes a latitudinal guide channel 64 arranged around the two semi-bladders 5. The latitudinal guide channel 64 narrows in the arch area 3. The latitudinal guide channel 64 near the outer periphery of the insole communicates with the outside of the insole at the boundary between the arch area 3 and the heel area 4. The guide channel 6 also includes a fourth longitudinal guide channel 66 connecting the two semi-bladders 5. The forefoot area 2 and the heel area 4 are each provided with at least three second radial guide channels 65. Each second radial guide channel 65 is the same as the semi-bladder 5 and extends outward along the radial direction of the semi-bladder 5 in a radial arrangement. The second radial guide channels 65 are connected to the latitudinal guide channels 64.
[0038] Furthermore, the ventilation holes 7 are located in the lateral guide groove 64 and the fourth longitudinal guide groove at the arch of the foot, or at the intersection of the second radial guide groove 65 and the lateral guide groove 64, or in the second radial guide groove 65, or in the area outside the guide groove 6. The ventilation holes 7 include the fourth ventilation hole 74 located in the arch area 3, and the fifth ventilation hole 75 located in the forefoot area 2 and the heel area 4.
[0039] Furthermore, the semi-cyst 5 has a height of 10mm, a length of 45mm, and a width of 25mm.
[0040] Furthermore, the width of the guide groove 6 is 2mm and the depth is 4mm. The diameter of the fifth ventilation hole in the forefoot area 2 and the heel area 4 is 2mm, and the diameter of the fourth ventilation hole in the arch area 3 is 2.5mm. This improves the breathability of the insole while ensuring its strength and integrity, preventing the insole from deforming, collapsing, or breaking under high stress.
[0041] The working principle is as follows: The heel area (4) and forefoot area (2) of the insole adopt a semi-bladder design. The insole is placed in the shoe cavity, and the semi-bladder and the sole form a closed air cavity. The guide groove (6) and the sole form a closed gas flow channel. During walking, the heel exerts pressure on the insole, the semi-bladder is squeezed, the internal air is squeezed out, and the air is squeezed into the guide groove. The gas flows through the guide groove to the arch area, forefoot area and edge of the insole body. There are ventilation holes in the guide groove. The gas enters between the insole and the foot through the ventilation holes. When the heel is lifted, with the assistance of the protrusion at the bottom of the semi-bladder, the semi-bladder quickly returns to its original shape, forming a negative pressure, which draws in the external air. This cycle makes the air in the shoe cavity flow, further enhancing the breathability. Meanwhile, the semi-bubble has good elasticity, which can effectively cushion the impact on the heel and is not easily deformed, providing a long-lasting and stable cushioning effect. The semi-bubble is molded in one piece from polyurethane high-foaming material and is integrally molded with the insole body, eliminating the need for additional suction devices, reducing the weight of the insole, and the drainage channel is located at the bottom of the insole, making the manufacturing process simple.
[0042] This utility model provides a multifunctional insole that utilizes a ventilation system formed by air holes and drainage channels, along with the air-pressure effect of the semi-bubble in the heel and forefoot areas. This significantly improves the insole's breathability, keeping feet dry and comfortable, reducing odor and bacterial growth, and providing excellent breathability. The semi-bubble design in the heel and forefoot areas effectively cushions the impact on the heel during walking, protecting foot joints and bones, reducing sports injuries. The raised bottom of the semi-bubble increases its thickness, ensuring the durability of the cushioning effect and providing excellent shock absorption. Several drainage channels on the bottom of the insole improve its anti-slip properties, making walking or exercise more comfortable and enhancing the overall wearing experience. The use of semi-bubbles to create air pressure eliminates the need for additional pressure devices, and the semi-bubble is molded from polyurethane high-foam material in one piece, integrally formed with the insole body. The multiple drainage channels and semi-bubble design make the insole lighter.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
