Respiratory insoles capable of changing air

Abstract

A breathing insole capable of ventilating, including an insole body (1) and a breathing air bag (3), which is characterized in that the breathing air bag (3) is connected with an exhausting tube (2) and an intake tube (4), a single-way vent valve (7) which can only charge air is arranged in joint of the intake tube (4) and the breathing air bag (3), and length of the intake tube (4) is adapted to heel height of a shoe body (5), a single-way vent valve (7) which can only discharge air is arranged in joint of the exhausting tube (2) and the breathing air bag (3), opening of the exhausting tube (2) is communicated with an opening hole (11) on front face of the insole body(1). Compared to the prior art, the insole of the invention can directly transport outside fresh air to inner chamber of shoes through the breathing air bag via the intake tube, which discharges moist air in the inner chamber of shoes for ventilation by each walking step rather than inter-replacement between moist airs in the inner chamber of shoes, design of the insole is very smart, thereby greatly improving ventilating quality, which brings shoe wearers more comfortable feelings and effectively promotes physical fitness of human body.

Description

technical field [0001] The invention relates to an insole, which can automatically generate air flow when walking, and can act as a breathable insole capable of shock absorption and ventilation. Background technique [0002] Most of the insoles are gaskets made of ordinary cloth, which is convenient to keep the sole surface clean, but this kind of insole only plays a role of isolation, and the comfort is not enough. Now, with the continuous improvement of people's living standards, protecting one's health has become the theme of life. The existing patent No. 02275651.5 is a Chinese invention patent titled "Double Air Cushion Breathing Shock Absorbing Insole", which proposes a structure, which is characterized in that the upper air cushion is composed of many evenly distributed hemispherical sealed air bags, and the upper air cushion There are many breathing holes in the space between each sealed airbag; the sealed airbags of the upper layer of air cushion and the sealed air...

AI Technical Summary

Problems solved by technology

But its disadvantage is that the design structure is more complicated, such as the insole has many holes and air bags, and the manufacturing process is more troublesome; more importantly, the ventilation of the insole is only the air in the inner cavity of the shoe, and the fresh air from the outside It is difficult to enter the shoe cavity for exchange, which will make it difficult to discharge the moist air in the shoe cavity, and it is difficult for the fresh air from the outside to enter the shoe cavity, which cannot achieve good ventilation and ventilation functions, so its structure Still need to be further improved
