The return pipe and secondary chamber can form a closed circulation path at low temperatures, continuously dispersing humid air from the forefoot area and preventing moisture retention.

Description

Technical Field

[0001] This invention relates to the field of athletic shoe technology, and in particular to an athletic shoe sole with a gradient temperature regulation structure and its molding process. Background Technology

[0002] Sports shoes are shoes designed and manufactured based on the characteristics of people participating in sports or travel. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. They are generally soft and elastic, which can provide a certain cushioning effect, enhance elasticity during exercise, and some can even prevent ankle injuries. Therefore, sports shoes are a better choice for sports or normal use.

[0003] An existing patent (publication number: CN120643001A) discloses a multifunctional temperature-regulating casual sports shoe and its manufacturing method. This sports shoe has semiconductor cooling layers embedded on both sides of the upper, and a flexible photovoltaic film on the tongue. The sole integrates a heating layer block containing heating wires, a piezoelectric power generation layer, a breathable cushioning block, and a heel structure. A fan, battery, and processor compartment are installed inside the heel structure's housing, and side door units with filters are located on both sides. The fan is connected to the air vent network of the breathable cushioning block via a pipe. The microprocessor connects to and controls each functional module. During manufacturing, a dedicated grooving device is used to process interconnected positioning grooves on the breathable cushioning block and heel structure assembly, and positioning blocks are then embedded and fixed in place.

[0004] Although this application achieves dynamic and precise temperature regulation of the shoe's internal microenvironment by integrating cooling, heating, airflow circulation, and piezoelectric and photovoltaic power generation functions into the shoe, combined with intelligent control and multi-path energy management, the temperature regulation structure of this application is relatively complex, involving the integration of multiple functional modules. This not only increases manufacturing costs and the overall weight of the sole, affecting comfort and flexibility during exercise, but also means that if any module malfunctions, it may affect the normal operation of the entire temperature regulation system. Summary of the Invention

[0005] The purpose of this invention is to provide a sports shoe sole with a gradient temperature regulation structure and its molding process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sports shoe sole with a gradient temperature regulation structure, comprising a base and a circulation component and a sealing component disposed inside the base, wherein a massage component is also installed on the surface of the base, the sealing component is disposed at both ends of the base and cooperates with the circulation component, the massage component is disposed on the forefoot of the base and is disposed above the circulation component;

[0007] The circulation component includes an air bladder cavity inside the base body. A first air inlet pipe is provided through the side of the air bladder cavity. A first one-way valve is installed on the surface of the first air inlet pipe. A second air inlet pipe is fixed to the other end of the first air inlet pipe. The second air inlet pipe is "tree branch-shaped". The second air inlet pipe is located at the forefoot of the base body and below the massage component. A return pipe is also connected to the side of the air bladder cavity. The other end of the return pipe is connected to the second air inlet pipe. An installation groove is provided on the surface of the base body. An air suction hole is provided on the side of the installation groove. The lower end of the air suction hole is connected to the second air inlet pipe.

[0008] The sealing assembly includes a telescopic rod fixed to the inner wall of the placement chamber, and a sealing block fixed to the other end of the telescopic rod. The sealing block is tightly fitted to the inner wall of the placement chamber. A temperature-sensitive memory spring is sleeved on the outer periphery of the telescopic rod. The two ends of the temperature-sensitive memory spring are respectively fixed to the inner wall of the placement chamber and the side of the sealing block. The sealing assembly is used to control the opening and closing of the connecting pipe and the exhaust hole. A filter screen is provided inside the exhaust hole.

[0009] The massage assembly includes a support plate, which is fixed to the inner wall of the mounting groove. A limit plate and a reset spring are fixed on the surface of the support plate. The reset spring is disposed inside the limit plate, and a fixing plate is fixed to the upper end of the reset spring. A mounting plate is rotatably connected to the upper surface of the fixing plate, and multiple massage protrusions are fixed to the upper surface of the mounting plate.

[0010] Preferably, the base has an exhaust hole on its side and a placement chamber inside the base. The exhaust hole is connected to the placement chamber. A connecting pipe passes through the side of the airbag cavity. A second one-way valve is installed on the surface of the connecting pipe. The other end of the connecting pipe is connected to the placement chamber. The airbag cavity is connected to the exhaust hole through the connecting pipe and the placement chamber.

[0011] Preferably, the side of the base is provided with multiple air inlets, and there are two sets of the connecting pipe, the second one-way valve and the sealing assembly. The intersection of the multiple air inlets is connected to the second air inlet pipe through another set of connecting pipe, the second one-way valve and the sealing assembly. The air intake directions of the two second one-way valves are opposite. The multiple air inlets are respectively located in the forefoot and arch areas of the sole. A sealing membrane is also provided inside the air inlet.

[0012] Preferably, a secondary chamber is further provided inside the base, and the reflux pipe is connected to the secondary chamber. The secondary chamber is located between the airbag cavity and the second air inlet pipe, and the volume of the secondary chamber is 1 / 4 to 1 / 3 of the airbag cavity.

[0013] Preferably, a slider is fixed to the inner wall of the mounting plate, and a groove corresponding to the slider is opened on the outer peripheral surface of the limiting plate. The slider moves inside the groove, and the groove is spiral-shaped. The mounting plate moves outside the limiting plate through the slider and the groove.

[0014] This invention also provides a molding process for a sports shoe sole with a gradient temperature regulation structure, comprising the following steps:

[0015] S1. Prepare the elastic material for forming the matrix, the pipes and valves for making the circulation components and sealing components, and the rigid plastic for the massage components, and pre-treat the raw materials.

[0016] S2. Place the pre-treated elastic material into a cavity that matches the shape of the shoe sole, and set the core and inserts inside the mold for forming the corresponding structures of the circulation component, sealing component and massage component. By heating and pressurizing, the elastic material is initially formed into a base shape in the mold.

[0017] S3. After the base body is initially formed, the pre-made first air inlet pipe, first one-way valve, second air inlet pipe and return pipe are installed in the corresponding positions inside the base body and fixed by welding and bonding. At the same time, the massage component is installed into the mounting groove on the surface of the base body.

[0018] S4. Next, install the sealing assembly inside the placement chamber, so that the sealing block fits tightly against the inner wall of the placement chamber. Then, install a filter screen inside the exhaust port and a sealing membrane inside the air inlet port.

[0019] S5. Place the sole back into the mold for a second pressurization and heating process. Once the sole has cooled and set, remove it from the mold and proceed with further finishing and processing.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. This invention utilizes foot pressure changes to enable the airbag cavity to perform compression for exhaust and negative pressure for intake. Combined with the directional guidance of the first air intake pipe and one-way valve, it ensures that humid air flows steadily into the airbag cavity and prevents backflow. The branch-shaped second air intake pipe evenly distributes moisture to the forefoot area, thereby increasing the absorption range of moisture. The return pipe and secondary chamber can form a closed circulation path at low temperatures, continuously guiding the humid air in the forefoot area and preventing moisture retention. At the same time, the temperature-sensitive memory spring can automatically expand and contract with temperature, moving the sealing block in the placement chamber to control the opening and closing of the passage. At low temperatures, it blocks the intrusion of external moisture, and at high temperatures, it opens the exhaust hole to release moisture.

[0022] 2. This invention uses a massage component to massage the soles of the feet during movement. The limiting plate prevents the return spring from shifting during compression and reset, ensuring that the mounting plate moves down synchronously with the foot pressure to open the air intake hole, allowing the air bladder cavity to absorb moisture generated during exercise. After the pressure disappears, it quickly resets and seals the hole. At the same time, the mounting plate and the silicone massage protrusions slide along the spiral groove via a slider, pressing and rotating to massage the soles of the feet, stimulating blood circulation and reducing sweating.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] This invention provides, for example Figures 1 to 7 The sports shoe sole with a gradient temperature regulation structure shown includes a base 1 and a circulation component 2 and a sealing component 3 disposed inside the base 1. A massage component 4 is also installed on the surface of the base 1. The sealing component 3 is disposed at both ends of the base 1 and cooperates with the circulation component 2. The massage component 4 is disposed on the forefoot of the base 1 and is disposed above the circulation component 2.

[0037] The circulation component 2 includes an air bladder cavity 201 inside the base 1. A first air inlet pipe 202 is provided through the side of the air bladder cavity 201. A first one-way valve 204 is installed on the surface of the first air inlet pipe 202. A second air inlet pipe 203 is fixed to the other end of the first air inlet pipe 202. The second air inlet pipe 203 is "tree branch-shaped" and is located at the forefoot of the base 1. The second air inlet pipe 203 is located below the massage component 4. A return pipe 205 is also connected to the side of the air bladder cavity 201. The other end of the return pipe 205 is connected to the second air inlet pipe 203. An installation groove 102 is provided on the surface of the base 1. An air suction hole 211 is provided on the side of the installation groove 102. The lower end of the air suction hole 211 is connected to the second air inlet pipe 203. The air intake pipe 203 is connected, and the air bladder cavity 201 can achieve compression for exhaust and negative pressure for intake under foot pressure changes, providing a stable airflow drive. In conjunction with the first air intake pipe 202 and the first one-way valve 204, it can not only guide air from the second air intake pipe 203 into the air bladder cavity 201, but also completely block the backflow of air inside the air bladder cavity 201 into the second air intake pipe 203, avoiding airflow turbulence that affects circulation efficiency. At the same time, the second air intake pipe 203, which is distributed in a tree-like pattern, can not only cover the toes and the middle of the forefoot that are prone to sweating, but also evenly disperse the incoming air, avoiding the temperature difference problem caused by concentrated airflow in a single area, and increase the contact area between the air and the forefoot area.

[0038] In addition, the return pipe 205 establishes a complete internal circulation path between the airbag cavity 201 and the second air inlet pipe 203. In low-temperature environments, compressed and heated air can flow repeatedly between the two, reducing heat loss. At the same time, when pressure is applied to the foot, the air inlet 211 on the surface of the base 1 can connect the second air inlet pipe 203 and the skin area of ​​the forefoot with the movement of the massage component 4. When the airbag cavity 201 is under negative pressure, it can draw out the humid and hot air generated by the forefoot, and quickly draw the moisture formed by the evaporation of sweat and the heat generated by exercise into the airbag cavity 201, avoiding the accumulation of stuffiness and keeping the skin of the forefoot dry.

[0039] An exhaust port 207 is provided on the side of the base 1, and a placement chamber 101 is provided inside the base 1. The exhaust port 207 is connected to the placement chamber 101. A connecting pipe 208 is provided through the side of the airbag cavity 201. A second one-way valve 209 is installed on the surface of the connecting pipe 208. The other end of the connecting pipe 208 is connected to the placement chamber 101. The airbag cavity 201 is connected to the exhaust port 207 through the connecting pipe 208 and the placement chamber 101. A filter screen is provided inside the exhaust port 207. The placement chamber 101 can buffer the airflow discharged from the airbag cavity 201 and reduce the noise generated by the high-speed airflow. The connecting pipe 208 connects to the airbag cavity 201. The air chamber 201 and the placement chamber 101 allow the air squeezed out of the air chamber 201 to flow quickly to the exhaust port 207. With the one-way passage of the second one-way valve 209 and the filter screen inside the exhaust port 207, it can prevent cold air, dust or ground moisture from entering the internal passage through the exhaust port 207 in the reverse direction. This not only avoids the internal heat being diluted by the cold air outside in low-temperature environments, but also prevents dust accumulation from causing passage blockage. At the same time, the air is circulated from the inside to the outside to the filter screen, which can use the airflow to wash away the dust attached to the surface of the filter screen, extend the service life of the filter screen, and ensure the one-way and long-term stability of air circulation.

[0040] The sealing assembly 3 includes a telescopic rod 301 fixed to the inner wall of the placement chamber 101, and a sealing block 303 fixed to the other end of the telescopic rod 301. The sealing block 303 fits tightly against the inner wall of the placement chamber 101. A temperature-sensitive memory spring 302 is sleeved on the outer periphery of the telescopic rod 301. The two ends of the temperature-sensitive memory spring 302 are fixed to the inner wall of the placement chamber 101 and the side of the sealing block 303, respectively. The sealing assembly 3 is used to control the opening and closing of the connecting pipe 208 and the exhaust port 207. The temperature-sensitive memory spring 302 can contract at low temperatures to move the sealing block 303 to block the passage, and extend at high temperatures to push the sealing block 303 to reset and open the passage. The fixed connection between the telescopic rod 301 and the sealing block 303 can stably transmit the telescopic force of the temperature-sensitive memory spring 302 to the sealing block 303, avoiding the displacement of the sealing block 303 during movement, thereby avoiding air leakage caused by misalignment of the sealing block 303.

[0041] Multiple air inlets 210 are also provided on the side of the base 1. There are two sets of connecting pipes 208, second one-way valves 209, and sealing components 3. The intersection of the multiple air inlets 210 is connected to the second air inlet pipe 203 through another set of connecting pipes 208, second one-way valves 209, and sealing components 3. The air intake directions of the two second one-way valves 209 are opposite. The multiple air inlets 210 are respectively located in the forefoot and arch areas of the sole. The number and diameter of the air inlets 210 in the forefoot area are larger than those in the arch area. A sealing membrane is also provided inside the air inlets 210. The multiple air inlets 210 distributed in the forefoot and arch areas of the sole can be differentiated according to the breathability and dehumidification needs of different foot areas. There are more air inlets 210 in the forefoot area. With a slightly larger aperture, more air can be introduced to accelerate ventilation and dehumidification at high temperatures. The air inlets 210 in the arch area are evenly distributed to meet the basic ventilation needs during support and prevent localized moisture buildup at the arch and sole contact points due to poor air circulation. At the same time, two independent connecting pipes 208, a second one-way valve 209, and a sealing component 3, in conjunction with the air bladder chamber 201, can form a complete ventilation and dehumidification closed loop, ensuring directional and orderly airflow. Furthermore, the waterproof and breathable sealing membrane inside the air inlet 210, utilizing the principle of heart valves, not only prevents external moisture from invading the sole but also automatically opens under foot pressure, allowing outside air to flow unidirectionally into the sole. Combined with the negative pressure intake and positive pressure exhaust of the air bladder chamber 201, a complete air circulation system is formed.

[0042] The base 1 also has a secondary chamber 206 inside, and the return pipe 205 is connected to the secondary chamber 206. The secondary chamber 206 is located between the airbag cavity 201 and the second air inlet pipe 203. The volume of the secondary chamber 206 is 1 / 4 to 1 / 3 of that of the airbag cavity 201. The secondary chamber 206 can buffer the airflow squeezed out of the airbag cavity 201. When the airbag cavity 201 is compressed and expelled, it enters the secondary chamber 206 for a short stay. This not only avoids the air directly impacting the inner wall of the second air inlet pipe 203 and causing impact damage to the tree-like branches of the second air inlet pipe 203, but also avoids the airflow whistling and reduces the noise during use. At the same time, the volume of the secondary chamber 206 is 1 / 4 to 1 / 3 of that of the airbag cavity 201, which can ensure sufficient buffer space without taking up too much space inside the sole due to excessive volume.

[0043] The massage component 4 includes a support plate 401, which is fixed to the inner wall of the mounting groove 102. A limit plate 402 and a return spring 403 are fixed to the surface of the support plate 401. The return spring 403 is located inside the limit plate 402, and a fixing plate 404 is fixed to the upper end of the return spring 403. A mounting plate 405 is rotatably connected to the upper surface of the fixing plate 404. Multiple massage protrusions 406 are fixed to the upper surface of the mounting plate 405. A slider 407 is fixed to the inner wall of the mounting plate 405. A groove 408 corresponding to the slider 407 is opened on the outer peripheral surface of the limit plate 402. The slider 407 moves inside the groove 408, which is spiral-shaped. The mounting plate 405 moves outside the limit plate 402 via the slider 407 and the groove 408. The limit plate 402 is annularly wrapped around the return spring 403, which can limit the extension and contraction direction of the spring, prevent its lateral displacement or twisting, and ensure that the mounting plate 405 is in a safe position. The groove 102 moves up and down, allowing the air inlet 211 to open stably under pressure and close promptly after the pressure is released. In conjunction with the return spring 403, when pressure is applied to the foot, the mounting plate 405 moves down to open the air inlet 211, allowing the negative pressure in the air chamber 201 to efficiently capture moisture from the forefoot. After the pressure is released, it quickly returns to its original position, causing the mounting plate 405 to seal the air inlet 211, preventing the negative pressure in the air chamber 201 from dissipating and ensuring effective moisture expulsion during the next squeeze, maintaining the continuity of the dehumidification cycle. Simultaneously, when pressure is applied to the foot, the massage protrusions 406 closely adhere to the skin of the forefoot, promoting blood circulation through pressure stimulation and reducing excessive sweating caused by poor circulation. Furthermore, the slider 407 slides within the spiral groove 408, causing the mounting plate 405 and massage protrusions 406 to rotate at a certain angle, enhancing the relaxation effect on the forefoot muscles and relieving exercise fatigue.

[0044] During use, when the body moves, the sole of the shoe is subjected to pressure from the foot. At this time, the air bladder 201 inside the base 1 is compressed, thereby expelling the air inside the air bladder 201 through the second one-way valve 209, the connecting pipe 208, and the exhaust port 207. At this time, a negative pressure environment is formed inside the air bladder 201. As the foot is lifted, the pressure exerted by the foot on the sole decreases, and the air bladder 201 begins to return to its original state. The negative pressure environment inside it causes outside air to pass through the air inlet 210 and another set of connecting pipes. The through-pipe 208 and the second one-way valve 209 (which is open due to the air intake direction setting) enter the second air intake pipe 203. Since the second air intake pipe 203 is "tree-branch-shaped" and located on the forefoot of the base 1, it can disperse air relatively evenly and enter the airbag cavity 201 through the first air intake pipe 202, completing one air circulation. Meanwhile, the pressure of the foot also acts synchronously on the forefoot part of the sole, causing the mounting plate 405 and massage protrusions located on the forefoot part to... Under pressure, 406 moves towards the mounting groove 102, thereby removing the shielding of the air intake 211 by the mounting plate 405. At this time, the second air intake pipe 203 connects to the forefoot area of ​​the athletic shoe through the air intake 211, allowing the negative pressure suction during the recovery process of the air bladder cavity 201 to act on the forefoot area of ​​the athletic shoe. That is, during the negative pressure suction process, the air bladder cavity 201 can draw heat and moisture generated in the forefoot area into the second air intake pipe 203 through the air intake 211, and as... The circulation of air carries heat and moisture out of the shoe, achieving temperature regulation in the forefoot area. At the same time, when the foot leaves the sole, the pressure disappears, and the mounting plate 405 returns to its original position under the action of the return spring 403. This shields the air intake hole 211, preventing the negative pressure of the air bladder cavity 201 from being dispersed. This ensures that the air bladder cavity 201 can only draw in air through the air intake hole 210, ensuring that the air bladder cavity 201 returns to its original position smoothly and preparing for the next compression to expel air, maintaining the cycle of compression to expel air and negative pressure to inhale air.

[0045] When the outside temperature is low, the temperature-sensitive memory spring 302 will contract due to the temperature drop, causing the telescopic rod 301 and the sealing block 303 to move inside the placement chamber 101 until the sealing block 303 completely blocks the connection between the connecting pipe 208 and the exhaust port 207 and the connection between the connecting pipe 208 and the air inlet 210. At this time, when the airbag cavity 201 is compressed, the air inside it cannot be discharged to the outside through the exhaust port 207, forming a positive pressure environment. This forces the gas to enter the secondary chamber 206 through the return pipe 205 and then into the second air inlet pipe 203. Since the second air intake pipe 203 is connected to the air inlet 211 at this time, under positive pressure, air can enter the forefoot area of ​​the athletic shoe in the opposite direction and blow on the forefoot area, forming a local air circulation, improving the breathability and dryness of the forefoot area. Furthermore, as the pressure applied to the foot decreases, the moisture in the forefoot area re-enters the air bladder cavity 201 through the air inlet pipe and the second air intake pipe 203, preventing moisture from accumulating locally. At the same time, the connecting pipe 208 and the air inlet 210 are blocked, preventing outside air from entering through the air inlet 210. The second air intake 203 prevents cold air from entering the shoe and causing a temperature drop, thus keeping the feet warm in low-temperature environments. As the body moves, the foot continuously applies pressure to the sole, causing the air bladder 201 to repeatedly compress and reset, driving air to form a closed-loop circulation between the air bladder 201, the second air intake 203, and the secondary chamber 206. This continuously ventilates the forefoot area, preventing moisture buildup. When vigorous exercise causes the internal temperature of the shoe to be high or the outside temperature to rise, the temperature-sensitive memory spring 302 will adjust accordingly. The extension and rise of the telescopic rod 301 and the sealing block 303 cause them to move in opposite directions inside the placement chamber 101, so that the sealing block 303 no longer blocks the connection between the connecting pipe 208 and the exhaust port 207. At this time, the air discharged from the airbag chamber 201 can be discharged to the outside through the exhaust port 207 normally. At the same time, the outside air enters the airbag chamber 201 through the air inlet 210, completing the air circulation. This allows the heat and moisture inside the sports shoe to be discharged to the outside with the air flow, achieving heat dissipation and dehumidification inside the sports shoe, keeping the inside of the sports shoe dry and comfortable.

[0046] When pressure is applied to the forefoot, the mounting plate 405 and massage protrusion 406 on the forefoot move towards the mounting groove 102 under pressure. At this time, the return spring 403 is compressed, and the slider 407 slides in the spiral groove 408, causing the mounting plate 405 and massage protrusion 406 to rotate at a certain angle. The massage protrusion 406 contacts the skin of the forefoot and produces a massage effect, promoting blood circulation in the foot and relieving exercise fatigue. When the foot pressure decreases or disappears, the return spring 403 returns to its original state, pushing the mounting plate 405 and massage protrusion 406 to move in the opposite direction. The slider 407 slides in the opposite direction in the groove 408, thereby pushing the mounting plate 405 and massage protrusion 406 back to their initial position.
