Breathing air change shoes and workmanship thereof

Abstract

The invention relates to shoes for daily wearing of people, in particular to breathing air change shoes and workmanship thereof. The breathing air change shoes have air changing and perspiring functions. The breathing air change shoes comprise uppers, insole elements and outsoles, and the insole elements are composed of insole base plates, air guide half sole pieces, second half sole pieces and air bag elements. Due to the fact that the air bag elements are connected with the insole base plates by the second half sole pieces to clamp the air bag elements between the insole base plates and the second half sole pieces to form a structure of the insole elements, the insole elements can be independently manufactured, and the workmanship is simple and convenient. Meanwhile, due to the fact that protruded limit protrusion blocks are arranged on the side faces of air bag bodies, the top distances between the limit protrusion blocks and the air bag bodies can be integrally pre-arranged according to requirements, when the insole elements are assembled, the exposed heights of the air bag bodies are kept to be completely consistent, product quality is stable, and percent of pass is high. In addition, due to the fact that the air bag elements are independently arranged on the insole elements, when the thicknesses of insoles are enough (for example, height increasing shoes are manufactured), air bag storage cavities do not need prearranging on heel portions of outsoles, common outsoles can be used to manufacture the breathing air change shoes, and shoe manufacturing technology is simplified.

Description

technical field [0001] The invention relates to shoes that people wear daily, in particular to a manufacturing process of breathing and ventilating shoes with functions of ventilating and sweating. Background technique [0002] The structure of traditional shoes such as leather shoes, sports shoes and the polyurethane upper injection molding shoes that come out later generally comprises upper of a shoe, inner bottom, middle bottom and outer bottom, and upper of a shoe is connected with outer bottom to form a shoe body. The midsole and upper of the polyurethane upper injection shoe are sewn together and placed on a special mold, and the polyurethane (PU) foaming liquid material is injected into the mold to form the shoe body. However, due to the compact structure of existing shoes, when wearing, the inner cavity of the shoe often forms a relatively closed space, and the air in the inner cavity of the shoe can hardly be exchanged with the outside air, especially the position w...

AI Technical Summary

Problems solved by technology

As can be seen from the above introduction, the production of existing breathing and ventilating shoes is relatively complicated, and because the sole and the upper need to be glued, it may cause the blockage of the airway mouth, affect normal work, and make it inconvenient, requiring more production personnel. In addition, there is no positioning mechanism for the high and low positions of the airbag body, resulting in inconsistent installation of the airbag body, resulting in unstable ventilation effects and difficult quality control
