Description

Technical Field

[0001] The invention relates to the technical field of sports shoes, in particular to a pair of sports shoes with a multi-layer composite sole. Background Art

[0002] Sports shoes are shoes designed and manufactured according to the characteristics of people participating in sports or traveling. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. They are generally soft and elastic, which can play a certain cushioning role and help protect people's feet when people exercise. At the same time, sports shoes can enhance people's elasticity when running and jumping during exercise, allowing people to exert better athletic ability. Therefore, when doing sports, most people have to wear sports shoes, especially high-intensity physical sports, such as basketball, running, etc.

[0003] Although sports shoes wrap people's feet and play a certain protective role, the wrapping of sports shoes on people's feet will lead to poor heat dissipation of the feet, and the feet will feel stuffy inside the shoes, making people very uncomfortable, which in turn affects people's exercise state. In addition, if the sweat on the feet cannot be quickly dissipated during exercise but is stuffy in the shoes, it is easy to have foot odor, which may form athlete's foot over time and affect people's health.

[0004] Currently, many sports shoes on the market are studying how to improve the heat dissipation performance of sports shoes and make them more breathable. For example, the Chinese invention patent with application number: CN202010631901.6 and titled "A kind of anti-odor sports shoes with strong heat dissipation" proposes a sports shoe, including a sole, a heat dissipation pad, a side pad and an upper, the bottom of the inner cavity of the sole contacts the heat dissipation pad, the left and right side walls of the inner cavity of the sole are bonded to the side pads, the top of the sole is bonded to the upper, the bottom of the sole is bonded with an anti-slip pad, through holes are provided on both sides of the anti-slip pad, the ends of the through holes pass through the bottom of the inner cavity of the sole, the top of the heat dissipation pad is integrally connected with a heat dissipation pad hole, the top of the heat dissipation pad is provided with a groove, the top of the heat dissipation pad is bonded with a main gripping plate and a secondary gripping plate, the tops of the main gripping plate and the secondary gripping plate are integrally connected with a bridge, a side pad groove is reserved inside the side pad, a slow-release plate is bonded inside the side pad groove, and a heat dissipation plate is bonded on the top of the slow-release plate. This patent uses a combination of accessories to combine through holes on the side of the anti-slip pad of the sole. The through holes penetrate the sole, and a cooling pad with a cooling pad hole is placed at the bottom. A gripping plate and a bridge are bonded to the top of the cooling pad to form a supporting structure, which can be used for support when the foot is placed. The internal heat can be combined with the cooling pad and the through holes to increase the heat dissipation effect. A side pad is combined on the inner side of the sole. The side pad of soft material has a slow-release plate inside. The slow-release plate can release the deodorizing material slowly and diffuse it with the cooling plate to reduce the odor inside the shoe.

[0005] However, the above invention patent adopts the form of natural heat dissipation by increasing holes. Although it improves the heat dissipation effect to a certain extent, the air flow inside the sports shoes is slow, the heat inside the shoes is slowly dissipated, and the odor is only temporarily adsorbed inside the slow-release plate and cannot be discharged from the shoes in time.

[0006] Therefore, a sports shoe with a multi-layer composite sole is proposed, which improves the heat dissipation and deodorization effects of the sports shoe by strengthening the air flow inside the sports shoe. Summary of the invention

[0007] The purpose of the present invention is to provide a sports shoe with a multi-layer composite sole, which can enhance the air flow inside the sports shoe to improve the heat dissipation and deodorization effects of the sports shoe, so as to solve the problem of the foot being easily stuffy inside the sports shoe mentioned in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A sports shoe with a multi-layer composite sole comprises a sole and an upper, wherein the upper is fixedly mounted on the sole, a shoe cavity for a foot to enter is formed between the upper and the sole, and the upper is further divided into a toe cap and a heel, the sole comprises a wear-resistant layer and a shock-absorbing layer, the shock-absorbing layer is made of EVA material, the wear-resistant layer is made of wear-resistant rubber, the wear-resistant layer is located below the shock-absorbing layer, the shock-absorbing layer is fixedly connected to the upper, a vent is provided on the side of the upper, the vent is connected to the shoe cavity, an air supply component is provided inside the shock-absorbing layer, the air supply component is connected to the vent, and the air supply component is used to supply air to the inside of the shoe cavity. The air supply component may be an air bag, an air pump, or a device that allows gas to ventilate the inside of the shoe cavity. The air supply component passes gas into the inside of the shoe cavity along the vent, driving the air flow inside the shoe cavity, and the gas is discharged from the outside of the shoe cavity after absorbing the heat generated by the foot during exercise, thereby improving the heat dissipation of the sports shoe and avoiding the problem of foot odor caused by the foot being suffocated inside the shoe cavity during exercise.

[0010] Preferably, the air supply assembly includes an air supply cavity opened inside the shock-absorbing layer, the cross section of the air supply cavity is a right-angled trapezoid, the upper bottom of the air supply cavity with a right-angled trapezoid cross section is shorter than the lower bottom, a "V"-shaped reed is arranged inside the air supply cavity, a return spring is arranged between the reeds, and the ventilation pipe is connected to the air supply cavity; when the air supply cavity is pressurized, the air inside the air supply cavity flows toward the inside of the shoe cavity along the ventilation pipe. The air supply cavity uses the action of pressing down and lifting the foot of a person to inhale and exhaust. When the air supply cavity is exhausted, the gas in the cavity is discharged into the inside of the shoe cavity along the ventilation pipe, disturbing the air inside the shoe cavity for heat dissipation, and when the air supply cavity is inhaled, the gas inside the shoe cavity is sucked into the air supply cavity, so that the gas inside the shoe cavity flows faster, thereby improving the heat dissipation effect of the foot inside the shoe cavity, making people more comfortable when exercising. The air supply cavity has a simple structure and will not increase the weight of the sports shoes too much, making it lighter when wearing sports shoes for exercise. The action of lifting and landing the foot of a person is used as power, and no additional control is required.

[0011] The cross section of the air supply cavity is a right-angled trapezoid, and the upper bottom is shorter than the lower bottom. The "V"-shaped reed is stuck at the bottom corner of the non-right-angled side of the right-angled trapezoid, which makes the air supply cavity more supportive and prevents the foot from suddenly sinking when pressing down, so that the sole of the foot is sufficiently supported when exercising. The reed and the return spring can also make the air supply cavity recover faster. At the same time, the spring is installed between the reeds to prevent the spring from piercing the shock-absorbing layer, thereby ensuring the service life of the sports shoes.

[0012] Preferably, an air intake pipe is provided on the upper of the shoe at the rear end, one end of the air intake pipe is connected to the air supply cavity, and the other end is fixed to the upper side of the upper of the shoe at the rear end, and the air intake pipe is provided with a first one-way component, and the first one-way component is used to limit the air to enter the air supply cavity only in one direction along the air intake pipe; the ventilation pipe is also provided with a second one-way component, and the second one-way component is used to limit the air to be discharged from the air supply cavity only in one direction along the ventilation pipe.

[0013] An air intake pipe, a first one-way component and a second one-way component are provided, so that when the air supply cavity is driven by the return spring to recover, it no longer absorbs the air inside the shoe cavity, but absorbs fresh air from the outside from the air intake pipe, so that the air supply cavity always supplies fresh air to the inside of the shoe cavity. Since the air supply cavity continuously supplies fresh air to the inside of the shoe cavity, the dirty air inside the shoe cavity can be discharged from the wearing port of the sports shoe, so as to avoid the air being trapped inside the shoe cavity and causing stink.

[0014] In addition, the outside air is cooler than the air inside the shoe cavity, and sending outside air into the shoe cavity helps dissipate heat.

[0015] The port of the air intake pipe for absorbing external air is located on the upper side of the shoe at the end of the shoe, which can reduce the possibility of dust absorption during outdoor sports, prevent dust from entering the air intake pipe and causing the air intake pipe to be blocked during outdoor sports, and prevent rainwater from entering from the air intake pipe opening when it rains or when the road is flooded, and prevent rainwater and accumulated water from entering the air supply cavity. Ensure that the air supply cavity is clean and tidy, and prevent dust and water from being pumped into the shoe cavity by the air supply cavity.

[0016] Preferably, a ventilation mesh is provided on the upper side of the toe of the shoe upper, and the connecting port of the ventilation pipe and the shoe cavity is located on the lower side of the ventilation mesh. People's toes are more prone to sweating, so a ventilation mesh is added at the toe to further improve the ventilation and heat dissipation effect of the shoe cavity. Providing the connecting port of the ventilation pipe and the shoe cavity on the lower side of the ventilation mesh helps to further improve the flow of air inside the shoe cavity, so that the air entering the shoe cavity through the air supply pipe can more quickly take the heat emitted by the foot out of the shoe cavity from the ventilation mesh.

[0017] Preferably, the vent is fixedly mounted on the outside of the upper, and the path of the vent is wavy, with the fluctuation amplitude of the vent in the wavy path gradually decreasing from the heel to the toe. Compared with installing the vent inside the upper (in the shoe cavity), installing the vent on the outside of the upper helps to prevent the vent from being squeezed, deformed and blocked by a person's foot, thereby ensuring smooth air supply of the vent and the heat dissipation effect of the sports shoes. The wavy path can increase the coverage area of ​​the vent on the upper, and utilize the process of air flowing in the vent to absorb the heat of the upper, thereby further dissipating the heat from the upper. The wavy vent can also play a decorative role on the upper, making the air supply duct less obtrusive and more beautiful on the sports shoes.

[0018] Preferably, the second one-way component includes a rotating plate and a limit block rotatably installed inside the ventilation pipe, the rotating plate is used to open or close the ventilation pipe, the limit block is used to limit the rotation angle of the rotating plate, and an exhaust port is also provided on the ventilation pipe. When the rotating plate is rotated to open the ventilation pipe, the rotating plate blocks and closes the exhaust port.

[0019] The air pressure inside the air supply cavity is used to control the rotation of the rotating plate. When the air supply cavity is pressurized, the gas flows toward the vent pipe and pushes the rotating plate. The rotating plate rotates to open the vent pipe. At this time, the rotating plate blocks the exhaust port and closes the exhaust port to prevent the gas from flowing out of the vent pipe from the exhaust port, ensuring that the gas flows to the shoe cavity. When the air supply cavity is restored under the action of the reed and the reset spring, the air supply cavity inhales negative pressure, and the rotating plate rotates and resets under the action of negative pressure, and the vent pipe is reclosed.

[0020] Since the negative pressure suction of the air supply cavity drives the gas of the ventilation tube to flow toward the air supply cavity, the ventilation tube also absorbs the gas inside the shoe cavity, and the gas inside the shoe cavity flows along the ventilation tube toward the direction of the air supply cavity. When the rotating plate closes the ventilation tube, the gas flowing out of the shoe cavity will hit the rotating plate. At this time, since the rotating plate no longer blocks the exhaust port, the gas flowing out of the shoe cavity that hits the rotating plate will be discharged from the ventilation tube through the exhaust port, thereby discharging the gas inside the shoe cavity to the outside of the shoe cavity, further improving the flow of gas inside the shoe cavity. At the same time, the setting of the rotating plate and the exhaust port enables the air supply cavity to drive the flow of gas inside the shoe cavity during the process of exhaust and suction (i.e., pressure and recovery), further improving the rate of gas flow inside the shoe cavity, and improving the heat dissipation and gas dispersion effects of the sports shoes.

[0021] Preferably, the shock-absorbing layer is horizontally provided with a drain port, the drain port is connected to the air supply cavity, and a closing plug for closing the drain port is threadedly connected at the drain port. If it rains heavily when exercising outdoors, rainwater may enter the air supply cavity. If rainwater enters the air supply cavity, the air supply cavity will easily pump water into the shoe cavity when supplying air to the shoe cavity. In addition, water may also enter the air supply cavity when washing shoes. After the air supply cavity is filled with water, the sports shoes will become heavier, which is not conducive to exercise. For this reason, a drain port is designed to discharge the water inside the air supply cavity after the air supply cavity is filled with water. The closing plug prevents the gas inside the air supply cavity from leaking from the drain port when the air supply cavity supplies air to the shoe cavity, and ensures the air pressure when the air supply cavity supplies air to the shoe cavity. The threaded closing plug helps to ensure the airtightness of the drain port, ensures the air pressure when the air supply cavity supplies air to the shoe cavity, and prevents the closing plug from falling from the drain port due to the internal pressure when the air supply cavity is compressed.

[0022] Preferably, a storage chamber is also provided in the shock-absorbing layer, and the storage chamber is connected to the drain port, and the storage chamber is used to store solid aromatherapy or solid perfume that can emit fragrance. Since the drain port is connected to the air supply cavity, the perfume will also enter the air supply cavity after emitting fragrance, and when the air supply cavity is ventilated toward the inside of the shoe cavity, the fragrance will also enter the inside of the shoe cavity, which helps to suppress the sweat odor of the feet and prevent foot odor after exercise.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The sports shoe with a multi-layer composite sole designed by the present invention is provided with an air supply component, and the air supply component is used to ventilate the inside of the shoe cavity, so that the gas inside the shoe cavity flows, and then the heat of the human feet is taken away by the air flow during the exercise of the human body, which helps the human feet to dissipate heat and also prevents the feet from being suffocated in the sports shoe and causing foot odor.

[0025] 2. The sports shoe with a multi-layer composite sole designed by the present invention is also provided with an air intake pipe. The air intake pipe is arranged at a higher position, which is helpful to provide fresh air to the air supply cavity of the air supply component and can effectively prevent the dust on the bottom surface from clogging the air intake pipe. In addition, a rotating plate is provided on the air pipe and an exhaust port is opened on the air pipe. The air inside the shoe cavity is sucked out through the suction action of the air supply cavity and discharged from the exhaust port, which further accelerates the air flow frequency in the shoe cavity and improves the heat dissipation effect.

[0026] 3. The sports shoe with a multi-layer composite sole designed by the present invention has a ventilation pipe arranged outside the upper, and the path of the ventilation pipe is wavy, which can increase the coverage area of ​​the ventilation pipe on the upper, and utilize the process of air flowing in the ventilation pipe to absorb the heat of the upper, thereby further dissipating the heat of the upper. The wavy ventilation pipe can also play a decorative effect on the upper, making the air supply pipe less obtrusive on the sports shoe and more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] See also Figures 1 to 9 The present invention provides a sports shoe with a multi-layer composite sole 1, and the technical solution is as follows:

[0038] A sports shoe with a multi-layer composite sole 1 includes a sole 1 and an upper 2, wherein the upper 2 is fixedly mounted on the sole 1, a shoe cavity 3 for a foot to enter is formed between the upper 2 and the sole 1, the upper 2 is further divided into a toe 201 and a heel 202, and an opening 16 for a foot to enter the shoe cavity 3 is also provided on the upper 2 at the heel 202, the sole 1 includes a wear-resistant layer 101 and a shock-absorbing layer 102, the shock-absorbing layer 102 is made of EVA material, and the wear-resistant layer 101 is made of wear-resistant rubber. The wear-resistant layer 101 is located below the shock-absorbing layer 102, and the shock-absorbing layer 102 is fixedly connected to the upper 2. An air supply assembly is arranged inside the shock-absorbing layer 102, and the air supply assembly includes an air supply cavity 5 opened inside the shock-absorbing layer 102, the cross section of the air supply cavity 5 is a right-angled trapezoid, the upper bottom of the air supply cavity 5 with a right-angled trapezoidal cross section is shorter than the lower bottom, and a "V"-shaped reed 6 is arranged inside the air supply cavity 5, and a return spring 7 is arranged between the reeds 6. A ventilation mesh surface 11 is arranged on the upper side of the toe 201 of the upper 2, and a plurality of through holes are arranged on the ventilation mesh surface 11, and the plurality of through holes connect the shoe cavity 3 with the external air. A ventilating pipe 4 is arranged on the side of the upper 2, and the ventilating pipe 4 is fixedly installed on the outside of the upper 2. The path of the ventilating pipe 4 is wavy, and the fluctuation amplitude of the ventilating pipe 4 of the wavy path gradually decreases from the shoe tail 202 to the shoe toe 201. One end of the ventilating pipe 4 is connected to the air supply cavity 5, and the other end is connected to the shoe cavity 3, and the connecting port between the ventilating pipe 4 and the shoe cavity 3 is located on the lower side of the ventilation mesh surface 11.

[0039] refer to Figure 4 and Figure 6 The shock absorbing layer 102 is horizontally provided with a drain port 13, which is located at the shoe tail 202, and is connected to the air supply cavity 5. A sealing plug 14 is threadedly connected to the drain port 13 for sealing the drain port 13. A storage chamber 15 is also provided in the shock absorbing layer 102, and the storage chamber 15 is connected to the drain port 13.

[0040] refer to Figures 3 to 5 as well as Figures 7 to 9The upper 2 at the shoe tail 202 is provided with an air intake pipe 8, one end of the air intake pipe 8 is connected with the air supply cavity 5, and the other end is fixed to the upper side of the upper 2 at the shoe tail 202. The air intake pipe 8 is provided with a first one-way component 9, and the first one-way component 9 can be a conventional one-way valve on the market. The first one-way component 9 is used to limit the air to enter the air supply cavity 5 only in one direction along the air intake pipe 8; the vent pipe 4 is also provided with a second one-way component 10, and the second one-way component 10 is used to limit the air to be discharged from the air supply cavity 5 only in one direction along the vent pipe 4. The second one-way component 10 includes a rotating plate 1001 and a limit block 1002 rotatably installed inside the vent pipe 4, the rotating plate 1001 is used to open or close the vent pipe 4, and the limit block 1002 is used to limit the rotation angle of the rotating plate 1001. The vent pipe 4 is also provided with an exhaust port 12, and when the rotating plate 1001 rotates to open the vent pipe 4, the rotating plate 1001 blocks and closes the exhaust port 12.

[0041] During use, refer to Figure 4 and Figure 6 First, rotate the closing plug 14 on the shock-absorbing layer 102 to open the drain port 13, then put the solid aromatherapy or solid perfume 17 from the drain port 13 into the storage chamber 15, and then re-tighten the closing plug 14 to re-close the drain port 13. Then, insert the foot into the shoe cavity 3 through the opening 16 and put on the sports shoe.

[0042] During exercise, refer to Figures 3 to 8 When a person steps down, the gravity of the person and the bottom surface squeeze the shock absorbing layer 102, causing the shock absorbing layer 102 to deform, thereby reducing the space of the exhaust cavity inside the shock absorbing layer 102. Due to the presence of the first one-way component 9, the gas in the exhaust cavity can only be discharged from the exhaust cavity outside through the vent pipe 4 connected to the exhaust cavity. When the air inside the exhaust cavity enters the vent pipe 4 and moves along the vent pipe 4, the airflow inside the vent pipe 4 will push the rotating plate 1001 inside the vent pipe 4. After being pushed by the airflow, the rotating plate 1001 rotates toward the exhaust port 12 to close the exhaust port 12, preventing the airflow from being discharged from the vent pipe 4 outside the vent pipe 4. Then the airflow continues to flow along the vent pipe 4, and absorbs part of the heat of the upper 2 when passing through the upper 2. Finally, the airflow inside the vent pipe 4 enters the shoe cavity 3 from the lower side of the ventilation mesh surface 11 to blow air and dissipate heat to the foot inside the shoe cavity 3. After the airflow enters the shoe cavity 3, it disturbs the air inside the shoe cavity 3. After the air inside the shoe cavity 3 is disturbed, it will flow out of the shoe cavity 3 through the ventilation mesh surface 11 and the opening 16. When the air inside the shoe cavity 3 flows out of the shoe cavity 3, the heat inside the shoe cavity 3 will also be taken out of the shoe cavity 3, thereby accelerating the heat dissipation of the human foot and making the person more comfortable when exercising.

[0043] At the same time, reference Figure 4 and Figure 6Since the solid aromatherapy or solid perfume 17 inside the storage chamber 15 will emit fragrance, the fragrance will flow into the shoe cavity 3 along with the air inside the air supply cavity 5, and finally the fragrance will also enter the shoe cavity 3, which helps to suppress the sweat odor of the feet and prevent foot odor after exercise.

[0044] When a person's feet are lifted from the ground, Figure 4 and Fig. 9 , the air supply cavity 5 is reopened under the action of the return spring 7 and the reed 6, the volume of the air supply cavity 5 is expanded, the pressure inside the air supply cavity 5 is reduced, and the air supply cavity 5 begins to inhale under the action of the negative pressure of the air supply cavity 5, and the gas inside the shoe cavity 3 flows along the vent pipe 4 toward the inside of the air supply pipe, and the negative pressure will drive the rotating plate 1001 to rotate toward the direction of the limit block 1002, and the rotating plate 1001 will eventually hit the limit block 1002 to close and cut off the vent pipe 4, and the exhaust port 12 will be reopened without the cover of the rotating plate 1001. At this time, the air flowing into the vent pipe 4 from the inside of the shoe cavity 3 continues to flow along the vent pipe 4 toward the air supply cavity 5 under the influence of inertia, and finally hits the rotating plate 1001. The air that hits the rotating plate 1001 flows toward the exhaust port 12 under the guidance of the rotating plate 1001, and finally is discharged from the exhaust port 12 to the vent pipe 4. When the air supply cavity 5 is reset to inhale air, the air inside the shoe cavity 3 can be pumped out of the shoe cavity 3 to dissipate heat and deodorize the inside of the shoe cavity 3 .

[0045] At this time, reference Figure 4 and Fig. 9 Since the rotating plate 1001 closes the ventilation pipe 4, the air supply cavity 5 can only suck the new air from the outside into the air supply cavity 5 from the air inlet pipe 8, preparing for the next time to send the gas into the shoe cavity 3.

[0046] This is repeated. When a person's foot steps on the ground, the air supply cavity 5 introduces fresh air into the shoe cavity 3, and the fragrance of the aromatherapy or perfume is also introduced into the shoe cavity 3, so as to dissipate heat and deodorize the person's foot. When the person's foot is lifted, the air inside the shoe cavity 3 is drawn out of the shoe cavity 3 from the exhaust port 12, and the hot air and sweat odor inside the shoe cavity 3 are drawn away, so as to further dissipate heat and deodorize the inside of the shoe cavity 3. Thus, the person's foot is protected and dissipated at all times during exercise, thereby improving the comfort of exercise.

[0047] After the exercise is finished, the solid aromatherapy or solid perfume cream 17 in the storage chamber 15 can be cleaned to prevent the solid aromatherapy or solid perfume cream 17 from deteriorating.

[0048] A specific embodiment of the present invention is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above described embodiment. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
