Description

Technical Field

[0001] This utility model relates to the field of casual shoes, and more particularly to a breathable casual shoe with a circulating air duct. Background Technology

[0002] As the main type of footwear for everyday wear, one of the core indicators of comfort for casual shoes is the breathability of the shoe cavity. The breathability of traditional casual shoes mainly relies on passive ventilation through the pores of the mesh material of the upper or simply by opening ventilation holes. Its ventilation efficiency is limited by the ambient wind force and walking posture, making it difficult to form a directional airflow circulation. Especially when worn for a long time, moisture and heat inside the shoe tend to accumulate in enclosed areas such as the soles and heels, leading to stuffiness, discomfort, and even bacterial growth. Therefore, there is an urgent need to develop a type of breathable casual shoe with a circulating air duct that can drive efficient ventilation inside the shoe, significantly improving breathability, dryness, and wearing comfort. Utility Model Content

[0003] In order to overcome the shortcomings of existing casual shoes, which mainly rely on passive ventilation through the pores of the mesh material of the upper or simply open ventilation holes to achieve breathability, making it difficult to form directional airflow circulation and resulting in poor breathability, this utility model aims to provide a circulating air duct breathable casual shoe that can drive efficient air exchange and ventilation inside the shoe, significantly improving the breathability, dryness and wearing comfort of the shoe.

[0004] This utility model is achieved by the following specific technical means: A breathable casual shoe with a circulating air duct includes a sole and an upper fixedly connected to the top of the sole; a first air chamber is disposed at the center of the forefoot area of ​​the sole; a second air chamber is disposed at the center of the heel area of ​​the sole; the first air chamber is connected to an exhaust channel in the toe area through a first air supply channel; the second air chamber is connected to an air intake channel in the heel area through a second air supply channel; a one-way air outlet valve is provided on the first air supply channel, allowing airflow only from the first air chamber to the exhaust channel; a one-way air intake is provided on the second air supply channel. The valve allows airflow only from the air inlet slot to the second air chamber; the side wall of the sole has a first air inlet hole communicating with the first air chamber, on which a one-way air inlet valve is installed, allowing only external airflow to enter the first air chamber; the side wall of the sole has a first air outlet hole communicating with the second air chamber, on which a one-way air outlet valve is installed, allowing only airflow to exit from the second air chamber; the upper surface of the toe area of ​​the sole has several second air outlet holes communicating with the exhaust slot; the upper surface of the heel area of ​​the sole has several second air inlets communicating with the air inlet slot.

[0005] Furthermore, both the first and second air chambers are elastic sealed cavities; this is achieved by the elastic deformation capability inherent in the sole material itself or by setting an elastic support structure on the inner wall; the volume decreases when compressed and increases when reset.

[0006] Furthermore, both the one-way exhaust valve and the one-way intake valve are silicone diaphragm valves.

[0007] Furthermore, both the exhaust groove and the air inlet groove are arc-shaped groove structures distributed along the edge of the sole; the second air outlet connected to the exhaust groove is distributed in an arc-shaped interval on the upper surface of the toe area; the second air inlet connected to the air inlet groove is distributed in an arc-shaped interval on the upper surface of the heel area.

[0008] Furthermore, the first air inlet on the sidewall of the sole is located on the sidewall of the forefoot area, and the first air outlet on the sidewall of the sole is located on the sidewall of the heel area.

[0009] Furthermore, the sole includes a fixedly bonded upper and lower sole; the first air chamber, the second air chamber, the first air inlet, the second air inlet, the exhaust groove, and the air inlet groove are formed on the corresponding surfaces of the upper and / or the lower sole; the first air inlet, the first air outlet, the second air inlet, and the second air outlet penetrate the sole or are formed on the upper and lower sole respectively; facilitating sole processing and forming.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves efficient air exchange and ventilation inside the shoe, significantly improving breathability, dryness, and wearing comfort.

[0011] This utility model of casual shoes utilizes the periodic pressure changes naturally applied by the sole of the foot to the sole during walking to drive the first and second air chambers in the forefoot and heel areas to alternately compress and reset. In conjunction with a one-way valve, air is guided to flow in a directional manner along a preset circulation channel, thereby achieving active and efficient ventilation of the shoe's interior space.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: Example

[0017] A type of breathable casual shoe with circulating air duct, such as Figure 1-3 As shown, the shoe includes a sole 1 and an upper 2 fixedly connected to the top of the sole 1; a first air chamber 11 is provided at the center of the forefoot area of ​​the sole 1; a second air chamber 12 is provided at the center of the heel area of ​​the sole 1; the first air chamber 11 is connected to the exhaust channel 14 in the toe area through a first air supply channel 13; the second air chamber 12 is connected to the air intake channel 16 in the heel area through a second air supply channel 15; a one-way exhaust valve 17 is provided on the first air supply channel 13, allowing airflow only from the first air chamber 11 to the exhaust channel 14; a one-way intake valve 18 is provided on the second air supply channel 15, allowing only... Airflow flows from the air inlet slot 16 to the second air chamber 12; the side wall of the sole 1 is provided with a first air inlet hole 19 communicating with the first air chamber 11, and a one-way air inlet valve 18 is installed on it, allowing only external airflow to enter the first air chamber 11; the side wall of the sole 1 is provided with a first air outlet hole 110 communicating with the second air chamber 12, and a one-way air outlet valve 17 is installed on it, allowing only airflow to exit from the second air chamber 12; the upper surface of the toe area of ​​the sole 1 is provided with several second air outlet holes 111 communicating with the exhaust slot 14; the upper surface of the heel area of ​​the sole 1 is provided with several second air inlet holes 112 communicating with the air inlet slot 16.

[0018] Working principle: This utility model of casual shoes utilizes the periodic pressure changes naturally applied by the sole of the foot to the sole 1 during walking to drive the first air chamber 11 and the second air chamber 12 in the forefoot and heel areas to perform alternating compression and resetting actions. With the help of a one-way valve, air is guided to flow in a directional manner along a preset circulating air channel, thereby achieving active and efficient ventilation of the shoe's interior space.

[0019] During the heel strike phase, body weight is concentrated on the heel area of ​​the sole 1, compressing the second air chamber 12 located there. Its volume decreases, and the internal pressure increases. The high-pressure gas overcomes the resistance of the one-way vent valve 17 on the first vent 110 and is directly discharged to the outside environment, completing one exhaust cycle. As the foot advances, the center of gravity shifts forward, the forefoot lands under pressure, and the heel lifts. At this time, the first air chamber 11 in the forefoot area is compressed, its volume decreases, and the internal gas pressure increases. This pushes the one-way vent valve 17 on the first air channel 13 to open, allowing gas to enter the exhaust groove 14 in the toe area through the first air channel 13. The gas is then evenly distributed to several second vents 111 arranged in an arc on the upper front surface of the sole 1, and finally injected upwards into the front space inside the shoe. Simultaneously, the lifting of the heel relieves the pressure on the second air chamber 12. Its elastic cavity begins to return to its original position due to the material's own deformation recovery force or the built-in support structure, increasing its volume and creating a negative pressure inside. This negative pressure is released through the second air channel... The air is conducted through the channel 15 to the air intake groove 16 in the heel area, and then acts on the second air intake hole 112 distributed on the upper surface of the heel of the sole 1 and connected to the air intake groove 16. At this time, there are two airflows in the shoe cavity: one is the newly injected, relatively cool and dry airflow at the front; the other is the original humid and hot air that is pushed backward by this new airflow. The negative pressure of the second air chamber 12 is just enough to efficiently draw the humid and hot air in the rear area of ​​the shoe into the air intake groove 16 through the second air intake hole 112, and then draw it through the second air delivery channel 15 to Inside the second air chamber 12; when the entire foot is fully lifted off the ground, the pressure on the forefoot is released, and the first air chamber 11 begins to reset under the action of elasticity. The cavity volume expands to form a negative pressure. This negative pressure acts on the one-way air intake valve 18 on the first air intake hole 19, drawing fresh air directly into the first air chamber 11, preparing for the compression and inflation when the forefoot hits the ground again. At this time, the second air chamber 12 in the heel has basically completed its reset and is filled with the humid and hot air drawn from inside the shoe, waiting for the compression and exhaust when the heel hits the ground again.

[0020] The cycle repeats itself, with each walking cycle driving the air to complete a closed-loop flow path. Without any external energy, relying solely on the kinetic energy of walking, a continuous unidirectional airflow circulation is formed inside the shoe, from the front to the middle to the rear, and finally from the rear to the back, significantly improving the breathability, dryness and wearing comfort of the shoe.

[0021] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
