Technical Field
[0001] This utility model relates to the field of footwear manufacturing technology, and in particular to a breathable children's sports shoe with bottom air channels. Background Technology
[0002] During daily activities, children's feet tend to sweat a lot due to their high activity levels, thus placing high demands on the breathability and moisture-wicking performance of athletic shoes. To improve the microclimate inside the shoe, existing breathable athletic shoes typically have exposed air channels on the side of the sole and ventilation channels that communicate with these channels are machined inside the sole.
[0003] During use, when the wearer steps down on the ground, the sole of the shoe is compressed. The hot and humid air inside the shoe is squeezed out through the ventilation channels and air channels. When the wearer lifts their foot off the ground, the elastic material of the sole rebounds and returns to its original position, increasing the internal space and creating a local negative pressure. This allows external air to be drawn back into the shoe cavity through the air channels. The passive exchange of internal and external gases is achieved through this simple mechanical compression and rebound.
[0004] Because the bottom air channels are open in both directions, when the wearer runs and jumps on puddles or muddy surfaces, the negative pressure generated by the rebound of the sole at the moment of foot lift will directly draw external sewage into the air channels and even deep into the shoe cavity. At the same time, mud and gravel from the road surface are easily pressed into and fill the recessed air channels under repeated trampling, and these impurities harden and clump after drying. Due to the lack of corresponding flow control and mechanical cleaning structures, once the channels are sealed shut by mud and sand, the airflow generated by normal trampling cannot clear them, completely blocking the ventilation channels of the sole, thus rendering the original breathability of the athletic shoe completely ineffective. Therefore, a breathable children's athletic shoe with bottom air channels is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a breathable children's sports shoe with a bottom air channel, which aims to solve the problem that the air channel of the sports shoe in the prior art is prone to backflow of sewage, and the groove opening is easily blocked by mud and sand, resulting in complete failure of breathability.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a breathable children's sports shoe with bottom air duct, comprising a sole body, an upper fixedly connected to the top of the sole body, and an exhaust anti-blocking component provided on the sole body; The exhaust anti-clogging component includes an internal negative pressure air chamber located inside the main body of the sole. An air inlet is located at the top of the main body of the sole, communicating with the internal negative pressure air chamber. A one-way suction diaphragm is fixedly connected to the inner wall of the air inlet, and a connecting ring is fixedly connected to the bottom of the one-way suction diaphragm. A V-shaped mud-removing plate is fixedly connected to the bottom of the connecting ring. An exhaust port is located at the bottom of the main body of the sole below the internal negative pressure air chamber, communicating with the internal negative pressure air chamber. An anti-backflow closing lip is fixedly connected to the inner wall of the exhaust port. The anti-backflow closing lip is V-shaped, and the V-shaped mud-removing plate is fitted in conjunction with the anti-backflow closing lip.
[0007] As a further description of the above technical solution: the inside of the shoe sole body is provided with an elastic reset component, the elastic reset component includes a limiting post, the limiting post is fixedly connected to the top and bottom surfaces of the inner wall of the internal negative pressure air chamber, the internal negative pressure air chamber is elastically connected by a reset spring, and the reset spring is respectively sleeved on the outer surface of the two limiting posts.
[0008] As a further description of the above technical solution: the upper is a flexible mesh structure that wraps around the back of the human foot, and the main body of the sole is a thickened arc-shaped structure that conforms to the contour of the human foot.
[0009] As a further description of the above technical solution: the internal negative pressure air chamber is a hollow, sealed cavity structure with an elliptical cross-section.
[0010] As a further description of the above technical solution: both the air inlet and the exhaust outlet are vertically penetrating cylindrical through-hole structures.
[0011] As a further description of the above technical solution: the one-way intake diaphragm has a micro-umbrella-shaped one-way valve structure that is thin at the edges and thick in the middle.
[0012] As a further description of the above technical solution: the connecting ring is a vertically distributed rigid hollow cylindrical structure.
[0013] As a further description of the above technical solution: the V-shaped mud discharge plate has a triangular wedge-shaped structure.
[0014] As a further description of the above technical solution: the anti-backflow closing lip has an elastic duckbill-shaped closing structure that converges and contracts downwards.
[0015] As a further description of the above technical solution: the reset spring is a high-tension helical metal disc spring structure, and the top and bottom ends of the reset spring are fixedly connected to the outer surfaces of the two limiting posts respectively.
[0016] This utility model has the following beneficial effects: 1. In this utility model, the exhaust anti-blocking component utilizes the air pressure from stepping to open the bottom anti-backflow closed lip for exhaust and drive the V-shaped mud discharge plate to crush mud and sand. When the foot is lifted, the negative pressure of the air chamber draws open the top one-way suction diaphragm to draw out moisture, while the bottom lip closes to prevent backflow, achieving dynamic one-way air circulation and mechanical self-cleaning effect. This solves the problem in the prior art that the air guide groove of sports shoes is prone to backflow of sewage, and the groove opening is easily blocked by mud and sand, resulting in complete failure of breathability.
[0017] 2. In this utility model, the elastic reset component is set up, and the reset spring releases its potential energy quickly after being compressed, causing the negative pressure air chamber to expand instantly and generate a strong vacuum suction force. The limiting post ensures the stability of the spring extension and contraction, thereby achieving a compensation effect of providing a lasting rebound force and air suction power. This solves the problem in the prior art that the sole rubber is prone to fatigue deformation after long-term stepping, which leads to the decay of the rebound force and the inability to maintain the continuous circulation of the internal air passage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Reference Figure 1 , Figure 2An embodiment of this utility model is provided: a breathable children's sports shoe with bottom air duct, including a sole body 2. The sole body 2 has a thickened arc shape structure that conforms to the contour of the human foot, providing a stable support base for the overall structure and reserving sufficient compression space for airflow circulation. The top of the sole body 2 is fixedly connected to the upper 1, which has a flexible mesh structure that wraps around the instep of the human foot, maintaining good breathability and moisture wicking performance while closely conforming to the foot. An exhaust anti-blocking component is provided on the sole body 2. Reference Figure 2 , Figure 3 The exhaust anti-clogging component includes an internal negative pressure air chamber 5, which is located inside the sole body 2. An air inlet 8 is provided at the top of the sole body 2 and is connected to the internal negative pressure air chamber 5. A one-way suction diaphragm 11 is fixedly connected to the inner wall of the air inlet 8. A connecting ring 6 is fixedly connected to the bottom of the one-way suction diaphragm 11 and a V-shaped mud discharge plate 7 is fixedly connected to the bottom of the connecting ring 6. An exhaust hole 3 is provided at the bottom of the sole body 2 below the internal negative pressure air chamber 5 and is connected to the internal negative pressure air chamber 5. An anti-backflow closing lip 4 is fixedly connected to the inner wall of the exhaust hole 3. The anti-backflow closing lip 4 is V-shaped and the V-shaped mud discharge plate 7 is configured to cooperate with the anti-backflow closing lip 4.
[0022] Reference Figure 3 , Figure 4 The sole body 2 is equipped with an elastic reset component inside. The elastic reset component includes a limiting post 9, which is fixedly connected to the top and bottom surfaces of the inner wall of the internal negative pressure air chamber 5. The internal negative pressure air chamber 5 is elastically connected by a reset spring 10. The reset spring 10 has a high-tension spiral metal coil spring structure, which can quickly release the stored elastic potential energy after the sole body 2 is compressed to provide an upward rebound force. The reset spring 10 is respectively sleeved on the outer surface of the two limiting posts 9, and the top and bottom ends of the reset spring 10 are fixedly connected to the outer surface of the two limiting posts 9, respectively, to ensure that the reset spring 10 remains axially stable along the limiting posts 9 and does not shift laterally when it is stretched or contracted under force.
[0023] Working principle: First, when the wearer's heel steps down, the heel area of the sole body 2 undergoes elastic deformation and is compressed downwards due to gravity and impact. This compression forces the internal negative pressure air chamber 5 inside the sole body 2 to contract rapidly, causing the air pressure inside the chamber to rise instantaneously. At this time, the one-way suction diaphragm 11 in the air inlet 8 at the top of the internal negative pressure air chamber 5 is impacted by the high-pressure airflow from below, and its edge tightly adheres to the inner wall of the air inlet 8, thus sealing the air intake channel and preventing the airflow from flowing back into the shoe upper 1. At the same time, the anti-backflow closure in the exhaust hole 3 at the bottom of the internal negative pressure air chamber 5 also closes. Under the downward push of the high-pressure airflow inside the cavity, the V-shaped flexible end of the lip 4 is forced to open outward. The original hot and humid gas inside the cavity then passes through the opened anti-backflow closed lip 4 and is discharged from the exhaust hole 3 to the outside of the shoe sole. During the same stroke when the internal negative pressure air chamber 5 is compressed, the V-shaped mud discharge plate 7 fixed to the bottom of the connecting ring 6 moves downward synchronously with the overall sinking of the top structure. Its inverted triangular wedge-shaped structure directly pierces into the gap of the anti-backflow closed lip 4, physically pushing and peeling away mud, scale and other debris that may adhere to or get stuck at the opening of the exhaust hole 3, completing a linkage work of exhaust and anti-blockage dredging.
[0024] Subsequently, when the wearer's heel is lifted and the center of gravity of the foot shifts forward, the pressure on the sole body 2 is released. The reset springs 10 on the surfaces of the two limiting posts 9 on the inner wall of the internal negative pressure air chamber 5 quickly release the accumulated elastic potential energy, pushing the top and bottom surfaces of the internal negative pressure air chamber 5 away from each other, causing the volume of the internal negative pressure air chamber 5 to expand and recover instantly. During this expansion and recovery process, a negative pressure vacuum state is instantly formed inside the internal negative pressure air chamber 5. Under this negative pressure, the anti-backflow closing lip 4 at the bottom is squeezed in the opposite direction by the external atmospheric pressure and mud and water pressure. Its V-shaped end instantly contracts inward and closes tightly, cutting off the path for external sewage to flow back into the internal negative pressure air chamber 5. Meanwhile, the one-way suction diaphragm 11 at the top is pulled open by the negative pressure suction force from top to bottom. With the opening of the one-way suction diaphragm 11, the sweat and humid air generated by the sole of the foot inside the shoe upper 1 are actively sucked into the internal negative pressure air chamber 5 through the air inlet 8 for temporary storage, waiting to be discharged when the heel is stepped on next.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
