Abstract

The utility model relates to ventilated shoes, which belongs to the footwear manufacturing. The technical problem which needs to be solved is that an air pump must have good elasticity and air tightness to enable the utility model to carry out normal ventilation operation. When people walk, feet are lifted up, and the air pump sucks air; an air inlet valve is opened and an air exhaust valve is closed, and waste air is sucked into an air chamber; a low pressure is formed in the shoes; under the action of atmospheric pressure, the environmental fresh air enters the shoes to supplement the low pressure in the shoes through capillary tubes arranged on the uppers of the shoes; when the feet fall down, the air pump carries out compressing and air exhaust, and the air inlet valve is closed and the air exhaust valve is opened; waste air is exhausted out of the shoes through the capillary tubes; the actions that the feet are lifted up and the air pump sucks air, and the feet fall down and the air pump exhausts are cycled, and thereby, the utility model takes the effect of ventilation and protecting the feet and the shoes.

Description

The ventilation footwear

The utility model is a kind ofly can discharge the footwear that footwear are taken a breath to air in the footwear outward.

The footwear gas permeability of selling in the market is poor, makes acid in the sweat, alkali, salt, urea etc. in a large number attached on footwear and the pin, and is very big to the corrosivity of footwear, reduced the service life of footwear greatly, improved the incidence of disease of pedopathy.

The purpose of this utility model provides a kind of ventilation footwear, and it can be discharged the air in the footwear outside the footwear, makes in the footwear and keeps dry.

The purpose of this utility model is achieved in that 1, when pin lifts, air pump is air-breathing, the air inlet one-way valve opens, form low pressure in the exhaust outlet closed check valve, footwear, under the atmospheric pressure effect, the capillary of outside fresh air on upper of a shoe enters in the footwear, replenishes the footwear air and recovers normal pressure; When 2, pin fell, air pump carried out compression exhaust, the air inlet closed check valve, and the exhaust outlet one-way valve opens, waste gas is outside capillary is discharged footwear.Like this, to lift air pump air-breathing for pin ... pin falls the air pump exhaust ... the effect of ventilation, protection pin and footwear is played in so circulation.

Owing to adopt such scheme, can make air and the exchange of footwear outer air in the footwear, keep the footwear inner drying.

Below in conjunction with drawings and Examples the utility model is further specified.
