Description

Technical Field

[0001] The utility model relates to the field of breathable insoles, in particular to an exhaust insole and a pair of shoes thereof. Background Art

[0002] Shoes are essential items in people's daily life. Men, women, old and young will use insoles when wearing shoes. Insoles not only have the function of adjusting the size of shoes, but also have the functions of absorbing sweat, removing bacteria and deodorizing. At present, most of the breathable insoles must cooperate with the soles or be integrated with the soles to produce their breathable function. They only have the hygienic function of isolating the feet and the soles. Their breathability is poor, and the air in the shoes cannot be fully circulated. Due to the poor air circulation in the shoes, the sweating of the feet is aggravated, and the feet are kept in a humid environment for a long time, especially for people with "sweaty feet". It not only causes foot odor, but also easily causes foot diseases. Existing shoes with breathable functions are provided with exhaust structures on the soles The ventilation device in which the air inlet valve and the air outlet valve are movably assembled on one side of the air chamber is placed in a groove in the front half of the sole. The air is renewed by the compression generated by the bending movement of the forefoot of the user when walking, and the shoe can be disassembled and cleaned at will to keep the shoe clean. However, an air valve component needs to be set, and the air valve has a high operating frequency. In sports such as running, the air valve will be subjected to a high frequency and large load. The movable parts in the air valve are prone to aging and failure. Moreover, a small amount of moisture in the shoe will enter the air valve, which may cause the movable parts to get stuck, thereby causing the air valve to fail and lose the ventilation effect. In addition, the thickness of the sole needs to be increased or the structure of the sole needs to be changed, which increases the production cost of the shoe. Utility Model Content

In this embodiment, the insole includes an upper insole 100 and a lower insole 200, which is convenient for manufacturing the air chamber 1 and the exhaust duct. An air inlet 3 and an air outlet 4 are respectively arranged at the head and tail ends of the exhaust duct. The air inlet 3 is arranged at a position corresponding to the forefoot and passes through the upper surface of the upper insole 100. The exhaust duct is a one-way air duct, and a conductive one-way airflow channel is formed from the air inlet 3 to the air outlet 4.

[0025] The exhaust duct includes an air intake duct connected between the air intake port 3 and the air chamber 1 and an air outlet duct 22 connected between the air chamber 1 and the air outlet 4. The air intake duct includes an air collecting channel 211, an air intake channel 212 and an air collecting chamber 213. The air collecting chamber 213 is connected between the air collecting channel 211 and the air intake channel 212.
