Description

A kind of breathable shock-absorbing children's foot protection shoes

technical field

The invention relates to a breathable and shock-absorbing children's foot protection shoe.

Background technique

Compared with other parts of the body, the airtightness of the shoe cavity is high. In the relatively closed environment of the shoe cavity, it is difficult to ventilate and ventilate. About 70%-80% of adults suffer from different degrees of foot fungal infections. Strong, can cause foot skin infection, resulting in swelling, odor, erosion, itching or redness, ulceration, peeling and other symptoms. Existing ventilation technologies mainly include vamp ventilation and sole ventilation, of which vamp ventilation accounts for the majority. Generally, there are a large number of openings on the upper, or mesh ventilation materials, which are generally suitable for use in warm areas or warm seasons. In the case of exercise, the ventilation of the instep is obviously better than that of the sole, and the ventilation effect of the sole is still insufficient; the conventional technology of sole ventilation includes airbag ventilation, generally using one or more airbags, in conjunction with one-way valve intake or exhaust. The disadvantage is that the sole of the foot is partially breathable, and it is difficult to realize the directional flow of the gas in the shoe cavity, so that the gas in the sole is continuously updated and good ventilation is achieved. Especially children's shoes, because children are in the stage of development and growth, the service life of children's shoes is shorter, and the size of children's shoes may not be suitable for children's feet within half a year or one year. Therefore, the functions of children's shoes for ventilation, shock absorption and foot protection are often neglected. The amount of exercise of children is much greater than that of most adults, so the ventilation, shock absorption and foot protection functions of children's shoes should be paid more attention.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a breathable and shock-absorbing children's foot protection shoe, which can greatly improve the ventilation function of the sole, reduce the flow of gas on the sole, thereby reducing the bacterial infection of the foot, and realize the functions of shock absorption and foot protection of the children's shoe.

The forefoot part of the sole is provided with a cavity, the air intake system is provided with an air intake groove, and the exhaust system is provided with an air discharge groove, and the air intake groove and the air discharge groove are connected to the upper end surface of the sole, the outer part of the shoe and all the other parts. The cavity, the air intake groove and the exhaust groove are connected with a one-way valve, the heel part can form an air intake system with the air intake groove and the cavity, and the forefoot part is composed of the exhaust groove and the cavity. The exhaust system, or the forefoot part, the air intake groove and the cavity constitute an air intake system, and the heel part, the exhaust groove and the cavity constitute an exhaust system, and the exhaust system and the air intake system pass through the air intake system. Air and exhaust change the air pressure of the shoe cavity to form a coordinated linkage.

Further, the upper end surface of the sole includes several first grooves connected with the air intake groove and several second grooves connected with the exhaust groove, the first grooves extend in the direction of the second grooves, and the first grooves extend in the direction of the second grooves. The two grooves extend in the direction of the first groove, and the first groove and the second groove are arranged alternately.

Further, an insole is also included, and holes are provided at least at the positions of the air inlet groove, the first groove and the second groove corresponding to the insole on the upper end surface of the sole.

Further, the diameter of the hole corresponding to the air inlet groove is larger than the hole corresponding to the first groove and the second groove, and the position of the insole corresponding to the exhaust groove is not provided with holes or a small number of holes are provided.

In the above-mentioned breathable and shock-absorbing children's foot protection shoes, the sole is provided with a higher shoe edge, and the air intake groove extends to the shoe edge.

Preferably, the air intake system and the exhaust system are independent components, and the sole includes an outermost wear-resistant layer, an inner elastic layer, and an air-intake system and an exhaust system embedded between the wear-resistant layer and the elastic layer. system, the air intake system and the exhaust system are glued with the wear layer and the elastic layer.

Preferably, the outlet connecting the outside of the air intake system and the exhaust system is provided on the side of the shoe sole, and the outlet is provided with a baffle to prevent rainwater from entering and a mesh layer to prevent sand from entering. .

The technical effects provided by the present invention are as follows:

1. The intake system and exhaust system of the present invention constitute a complete intake and exhaust system as a whole. When the cavity of the intake system is pressurized, the volume decreases, the pressure in the air rises, and the one-way valve prevents the gas from being discharged to the outside world. The gas in the cavity is squeezed to the shoe cavity along the air inlet groove, and is sent to all parts of the entire sole along the first groove. In the prior art, ventilation is often concentrated on the limitation of part of the sole of the foot. When the cavity of the air intake system is restored, the air pressure in the cavity decreases and the gas flows to the cavity. At this time, the air intake groove connected to the outside is straight and large in size. , the external air is easier to flow than the shoe cavity air, and the external air fills the cavity. At this time, the air pressure in the shoe cavity is in a relatively high state. Due to the lift of the foot, the sole and the sole are no longer in a pressing state, the contact between the sole and the sole is reduced, and the gas in the shoe cavity continues to flow in the direction of lower local air pressure. , then the exhaust system is pressurized, and the gas in the cavity of the exhaust system is squeezed out of the outside world. When the foot is lifted, the air pressure in the cavity is reduced because the outside air of the one-way valve cannot enter, and the cavity of the exhaust system is connected to the foot. The channel between the soles is opened, and the sole air flows to and fills the cavity. After the exhaust system of the present invention is exhausted, the gas under the foot flows to the cavity, causing the pressure of the sole to decrease, and it is easier to take in the next intake system. The exhaust of the next exhaust system is more efficient. At the same time, the cooperation of the intake system and the exhaust system allows the gas to flow on the sole of the foot. Compared with the traditional single ventilation system, the ventilation efficiency is greatly improved, so that the entire sole of the foot is fully ventilated. It is within the scope of the exchange of ventilation, thus avoiding the lack of local ventilation.

2. The corresponding position of the air inlet slot on the insole has a larger aperture. When taking in air, the forefoot of the foot presses the position of the insole corresponding to the air inlet slot. At this time, the air intake effect becomes poor, so the opening here is larger, which is beneficial to Air intake, the opening of the insole at the corresponding position of the first groove is small, in order to avoid excessive air intake in a single opening, to ensure that enough air is sent to the sole of the shoe along the first groove, so that all parts of the sole can participate. Air circulation, conveyed by air intake, pushes the old air in the shoe cavity to the exhaust end, which is conducive to the discharge of the old air in the shoe cavity, and the cycle goes back and forth to maintain the freshness of the air in the shoe cavity. When exhausting, the airflow near the exhaust slot first flows to the cavity. If the insole corresponding to the exhaust slot is provided with a large number of holes for convenient exhaust, the pressure difference across the sole will disappear quickly, resulting in the leakage of air away from the exhaust slot. Air flow is difficult to be excluded, the insole position corresponding to the insole exhaust groove of the present invention has no holes or less holes and the aperture on the second groove is slightly smaller, which not only ensures the exhaust, but also does not make the exhaust volume of a single hole too large, It can maintain the pressure difference between the cavity and the shoe cavity, and cooperate with the principle of the air intake system. Cavity ventilation efficiency.

3. The outlet of the air intake system and exhaust system is located on the side of the sole instead of the sole, which can be waterproof. The shielding sheet and mesh layer of the outlet can prevent dust and gravel from entering the sole and avoid affecting the wearing comfort.

4. The forefoot and heel of the sole are made of elastic material, and the setting of the cavity can provide a certain function of shock absorption, shock absorption and rebound. Function, the higher shoe edge can extend the air intake groove to the shoe edge, when the air is taken in, the gas can be blown from the shoe edge to the side of the foot to further improve the effect of air intake.

Referring to FIG. 4, a cavity 15 is provided in the heel part of the sole, and the exhaust system 4 There is an exhaust slot 401, the intake slot 301 and the exhaust slot 401 are connected to the upper end surface of the sole, the outer part of the shoe and the cavity 15, the intake slot 301 and the exhaust slot 401 are connected with a one-way valve 5, the said The forefoot part, the air intake groove 301 and the cavity 15 constitute the air intake system 3 , and the heel part, the air exhaust groove 401 and the cavity 15 constitute the exhaust system 4 , and the exhaust system 4 and the air intake system 3 pass through Intake and exhaust change the air pressure of the shoe cavity to form a coordinated linkage. Of course, the air intake system 3 can also be arranged at the heel portion, and the exhaust system 4 is arranged at the forefoot portion.

In the above embodiment, as shown in FIG. 2 , the upper end surface of the sole includes a plurality of first grooves 302 connected with the air intake groove 301 and a plurality of second grooves 402 connected with the exhaust groove 401 . The groove 302 extends toward the exhaust system 4 , the second groove 402 extends toward the intake system 3 , and the first groove 302 and the second groove 402 are alternately arranged. The first groove 302 extends in the direction of the exhaust system 4, which can transport the intake air to the exhaust end, and the gas in the shoe cavity is pushed to the exhaust end, which is beneficial to the exhaust of the exhaust system 4. Similarly, the second groove The effect of 402 extending in the direction of the air intake system is similar. The first groove 302 and the second groove 402 are arranged alternately, and the distance between the first groove 302 and the second groove 402 is not too far, which is conducive to the intake air from the first groove. The direction of the groove 302 flowing to the second groove 402 helps the shoe cavity gas to flow from the air intake system 3 to the exhaust system 4 , and the shoe cavity gas flows from the first groove 302 to the second groove 402 . Generally speaking, the first groove 302 and the second groove 402 are not connected to prevent the air in the first groove 302 from directly flowing to the second groove 402 and finally discharged out of the shoe, which affects the ventilation effect of the sole.

In the above-mentioned embodiment, as shown in FIG. 5 , an insole 6 is also included, and a hole 7 is provided at least at the position of the insole 6 corresponding to the air inlet groove 301 , the first groove 302 and the second groove 402 on the upper end face of the sole, The external air flows to the sole of the foot along the air intake groove 301, the first groove 302, and the hole 7 on the insole 6, and the internal air is discharged out of the shoe along the hole 7 on the insole 6, the second groove 402, and the exhaust groove 401. .

In the above embodiment, referring to FIG. 5 , the diameter of the hole 7 of the insole 6 corresponding to the position of the air inlet groove 301 is larger than that of the hole 7 of the insole 6 corresponding to the position of the first groove 302 and the second groove 402 , and the exhaust groove 401 The corresponding position of the insole 6 is not provided with holes 7 or a small amount of holes 7 are provided.
