Description

Technical Field

[0001] This application relates to the field of functional boot technology, and in particular to a shoe sole with sound-absorbing, ventilation and drainage functions. Background Technology

[0002] Shoe soles with drainage function are usually used in rainy days, muddy ground, and special work scenarios, such as mines, fire fighting, factories, and training grounds. They have a strong drainage effect through the changes in air chambers inside the sole.

[0003] Existing shoe soles with drainage function usually achieve drainage through drainage holes or valves. However, these small holes have a small diameter and the gas or liquid flow rate is relatively fast. When the airflow passes through at high speed, it will generate a "hissing" noise due to friction, which greatly affects the wearing experience. In response to the above-mentioned related technologies, the applicant proposes a shoe sole with noise reduction, ventilation and drainage functions, which can reduce the noise generated during drainage and avoid affecting the wearing experience. Utility Model Content

[0004] In order to reduce the noise generated during drainage and avoid affecting the wearing experience, this application provides a shoe sole with noise reduction, ventilation and drainage functions.

[0005] The shoe sole with noise reduction, ventilation, and drainage functions provided in this application adopts the following technical solution:

[0006] A shoe sole with sound-absorbing, venting, and drainage functions includes an outsole, an elastic midsole bonded to the inner side of the outsole, a venting and drainage cavity formed on the side of the midsole near the inner surface of the outsole, the venting and drainage cavity being compressible or expandable with the elastic deformation of the midsole, and venting and drainage one-way valves respectively provided on the inner and outer sides of the corresponding venting and drainage cavities; the venting and drainage one-way valves connecting the venting and drainage cavities from the outside to the inside are connected to the upper surface of the midsole, and the drainage end of the venting and drainage one-way valves is provided with a water-absorbing and sound-absorbing structure, the water-absorbing and sound-absorbing structure being porous and having water permeability and air permeability; the venting and drainage one-way valves connecting the venting and drainage cavities from the inside to the outside are provided with a drainage and sound-absorbing structure, the drainage and sound-absorbing structure being curved and connected between the water outlet end of the venting and drainage one-way valve and the atmosphere.

[0007] By adopting the above technical solution, an air venting and drainage chamber is set inside the shoe midsole, and rapid drainage is achieved through air venting and drainage one-way valves set in opposite directions on the inner and outer sides. The air venting and drainage chamber is compressed or expanded with the elastic deformation of the shoe midsole, ensuring that the water is effectively discharged under the pressure of the foot. The porous water absorption and sound absorption structure weakens the noise generated by the friction between airflow and liquid, reduces the sound transmission ability during drainage, and avoids the straight-line propagation of sound waves through the design of curved and connected extension tubes and noise reduction plates, further reducing drainage noise and thus achieving the effect of sound absorption.

[0008] Preferably, the water-absorbing and noise-absorbing structure includes a support frame and a sponge tube. The support frame is sleeved on the outlet end of the exhaust and drainage check valve that connects to the exhaust and drainage chamber from the outside to the inside, and the support frame extends toward the outlet end of the exhaust and drainage check valve. The sponge tube is fixed to the support frame and is hollowly sleeved on the outlet end of the exhaust and drainage check valve.

[0009] Preferably, the water-absorbing and noise-reducing structure further includes a water-guiding bracket, which is housed inside the sponge tube and fixed to the support frame. The water-guiding bracket is tapered, with the cone head facing the discharge end of the exhaust and drainage check valve.

[0010] Preferably, the drainage noise reduction structure includes an extension pipe and noise reduction plates. The extension pipe is sleeved on the outlet end of the exhaust and drainage check valve that connects to the exhaust and drainage chamber from the inside to the outside. The extension pipe is connected to the exhaust and drainage check valve and passes through the outsole of the shoe to connect to the atmosphere. The noise reduction plates are respectively staggered and fixed on the inner side of the extension pipe, and the projection of several noise reduction plates along the extension direction of the extension pipe covers the inner diameter shape of the extension pipe.

[0011] Preferably, the noise reduction sheets are arranged in a spiral along the inner wall of the extension tube.

[0012] Preferably, the noise reduction sheet extends to the axis of the extension tube, and several noise reduction sheets are fixedly connected to the axis of the extension tube.

[0013] Preferably, the noise reduction plate is blade-shaped, with one side of the noise reduction plate fixed to the inner wall of the extension tube being narrower and the other side being wider at the axis of the extension tube.

[0014] Preferably, the upper surface of the shoe midsole is provided with a plurality of first water guide grooves extending in all directions, and the lower surface of the shoe midsole is provided with a second water guide groove. One end of the second water guide groove is connected to the first water guide groove, and the other end is connected to the water inlet end of the exhaust and drainage check valve that connects from the outside to the inside of the exhaust and drainage chamber.

[0015] Preferably, the first water guide channel is inclined along the upper surface of the shoe midsole, and the second water guide channel is connected to the lowest end of the first water guide channel.

[0016] By adopting the above technical solution, the inclined design of the first water channel combined with the precise connection of the second water channel can minimize the retention of water inside the shoe and keep the inside of the shoe dry. Through the setting of two layers of water channels, the dry and wet inside the shoe can be separated, ensuring wearing comfort.

[0017] Preferably, the outsole is made of rubber and the midsole is made of PU foam.

[0018] By adopting the above technical solution, the PU foam material is lightweight, reducing the overall weight of the shoe and improving wearing comfort. The combination of the two materials not only improves the wearing experience but also enhances the overall durability of the sole, making it suitable for various complex environments.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The shoe midsole features an air venting and drainage chamber, which is equipped with one-way valves for air venting and drainage arranged in opposite directions on the inside and outside to achieve rapid drainage. The air venting and drainage chamber compresses or expands with the elastic deformation of the midsole, ensuring that water is effectively discharged under the pressure of the foot. The porous water absorption and sound absorption structure reduces the noise generated by the friction between airflow and liquid, reducing the sound transmission capability during drainage. The curved and connected extension tube and noise reduction plate design prevent the straight-line propagation of sound waves, further reducing drainage noise and achieving a sound-absorbing effect.

[0021] The sloping design of the first water channel, combined with the precise connection of the second water channel, minimizes water retention inside the shoe, keeping the inside dry. The two-layer water channel design achieves dry and wet separation inside the shoe, ensuring wearing comfort.

[0022] PU foam material is lightweight, reducing the overall weight of the shoe and improving wearing comfort. The combination of the two materials not only enhances the wearing experience but also strengthens the overall durability of the sole, making it suitable for various complex environments.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a shoe sole with noise reduction, ventilation, and drainage functions, as shown in the embodiments below. Figure 1 , 2The shoe includes an outsole 1, which is made of rubber and is tough, wear-resistant, and puncture-resistant, providing good wearing strength. A midsole 2 is bonded to the inside of the outsole 1. A ventilation and drainage cavity 3 is formed on the side of the midsole 2 near the inner surface of the outsole 1. The midsole 2 is made of PU foam material and has high elasticity, providing shock absorption and cushioning to improve wearing comfort.

[0031] Reference Figure 1 , 2 The ventilation and drainage chamber 3 undergoes elastic deformation during wear, which compresses or expands. The midsole 2 is equipped with ventilation and drainage one-way valves 4 arranged in opposite directions on the inner and outer sides of the ventilation and drainage chamber 3 to quickly drain water from inside the shoe.

[0032] Reference Figure 1 , 2 The exhaust and drainage check valve 4, which connects to the exhaust and drainage chamber 3 from the outside to the inside, is connected to the upper surface of the shoe midsole 2. The upper surface of the shoe midsole 2 is provided with several first water guide grooves 7 extending in all directions. The first water guide grooves 7 are inclined along the upper surface of the shoe midsole 2. Taking advantage of the inclination of the shoe midsole 2, the water on the upper surface of the shoe midsole 2 is collected at the lowest point of the first water guide groove 7 through the first water guide groove 7. A second water guide groove 8 is provided on the lower surface of the shoe midsole 2. One end of the second water guide groove 8 is connected to the lowest end of the first water guide groove 7, and the other end is connected to the water inlet end of the exhaust and drainage check valve 4, which connects to the exhaust and drainage chamber 3 from the outside to the inside. This achieves dry and wet separation on the upper and lower sides of the shoe midsole 2 and guides the water to the exhaust and drainage check valve 4, which opens towards the inside of the exhaust and drainage chamber 3, with maximum efficiency.

[0033] Reference Figure 3 , 4 When the exhaust drain chamber 3 is compressed and returns to its original shape, it generates an expansion force, which creates a negative pressure inside the exhaust drain chamber 3. This draws water from the second water guide trough 8 into the exhaust drain chamber 3, thus ensuring the water flow. Since the pressure inside the exhaust drain chamber 3 is continuous, when the water volume in the second water guide trough 8 is insufficient, friction between air and liquid and the exhaust drain check valve 4 generates sound, forming the jet sound of airflow. The drain end of the exhaust drain check valve 4 is equipped with a water-absorbing and sound-absorbing structure 5 to reduce the sound transmission capability.

[0034] Reference Figure 3 , 4The water-absorbing and noise-absorbing structure 5 includes a support frame 51 and a sponge tube 52. The support frame 51 is sleeved on the outlet end of the exhaust and drainage check valve 4, which connects to the exhaust and drainage chamber 3 from the outside to the inside, and the support frame 51 extends towards the outlet end of the exhaust and drainage check valve 4. The sponge tube 52 is fixed to the support frame 51 and is hollowly sleeved on the outlet end of the exhaust and drainage check valve 4. The sponge tube 52 has the characteristic of allowing gas and liquid to flow, which can allow gas and liquid to be discharged smoothly. Its porous structure can weaken the transmission of noise, thereby reducing noise. The installation through the support frame 51 can ensure the stability of the sponge tube 52 installation, and the sponge tube 52 will not fall off during the running and jumping process.

[0035] Reference Figure 3 , 4 The water-absorbing and noise-absorbing structure 5 also includes a water-guiding bracket 53, which is housed inside the sponge tube 52 and fixed to the support frame 51. The water-guiding bracket 53 is tapered, with the cone head facing the discharge end of the exhaust and drainage check valve 4. When the water flow discharged from the exhaust and drainage check valve 4 is large, the water-guiding bracket 53 can guide the water flow, allowing the water flow to diffuse to the side wall of the sponge tube 52 for discharge, thus avoiding disorderly impact of the water flow in the sponge tube 52, which would reduce the drainage efficiency.

[0036] Reference Figure 3 , 5 Since sponges are prone to aging when exposed to sunlight, a drainage and noise reduction structure 6 is provided on the exhaust and drainage check valve 4 that connects the exhaust and drainage chamber 3 from the inside out. The drainage and noise reduction structure 6 includes an extension pipe 61 and noise reduction plates 62. The extension pipe 61 is sleeved on the water outlet end of the exhaust and drainage check valve 4 that connects the exhaust and drainage chamber 3 from the inside out, and the extension pipe 61 is connected to the exhaust and drainage check valve 4 and passes through the outsole 1 of the shoe to connect to the atmosphere. The noise reduction plates 62 are respectively fixed to the inside of the extension pipe 61 in a staggered manner to ensure the discharge of water and air. The projection of several noise reduction plates 62 along the extension direction of the extension pipe 61 covers the inner diameter shape of the extension pipe 61 to avoid the straight-line propagation of sound waves and weaken them by blocking the noise reduction plates 62.

[0037] Reference Figure 3 , 5 The noise reduction sheet 62 can be arranged spirally along the inner wall of the extension tube 61, so that the flow path of air or water is uniform and the discharge is smoother; the noise reduction sheet 62 extends to the axis of the extension tube 61, and several noise reduction sheets 62 are fixedly connected to the axis of the extension tube 61 to avoid vibration of the noise reduction sheet 62 during running and jumping, and at the same time, it is beneficial to increase the volume of the noise reduction sheet 62 and improve the noise reduction capability.

[0038] Reference Figure 3 , 5The noise reduction plate 62 is preferably blade-shaped. The noise reduction plate 62 is fixed to the inner wall of the extension tube 61. One side is narrower and the other side is wider at the axis of the extension tube 61. The wider part can effectively reduce noise, while the narrower part is close to the inner wall of the extension tube 61. During the activity, the liquid discharge will be affected by the inertia of the shoe and will be close to the wall of the extension tube 61, which makes it easier for the liquid to be discharged.

[0039] The working process of this application is as follows: the foot applies pressure to the exhaust and drainage chamber 3, and the water in the exhaust and drainage chamber 3 is discharged through the exhaust and drainage one-way valve 4 connected to the atmosphere. At the same time, it is filtered by the drainage and noise reduction structure 6 to avoid excessive noise. When the foot is lifted, the exhaust and drainage chamber 3 recovers its shape through the elasticity of the shoe midsole 2, generates negative pressure and draws water from the second water guide groove 8 into the exhaust and drainage chamber 3. The water absorption and noise reduction structure 5 isolates the sound wave propagation to reduce noise.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
