Comfortable foaming EVA slipper and manufacturing process

Abstract

The invention discloses a comfortable foaming EVA slipper and manufacturing process. The comfortable foaming EVA slipper comprises a vamp and a sole, and is characterized in that the sole is provided with a first air cushion cavity located below the foot sole and a second air cushion cavity located below the heel, and a third storage cavity is formed between the first air cushion cavity and the second air cushion cavity; the first air cushion cavity and the second air cushion cavity are internally provided with a plurality of sealed air bags, an air outlet channel located in the side wall and an air inlet channel connected with the third storage cavity, air passes through the air outlet channel and the air inlet channel in a one-way guiding mode, and the third storage cavity is internally provided with a storage bag capable of being detached relative to the shoe sole. According to the slipper, the sealed air bags are arranged to form the air springs, the double air cushion cavities of the sole and the heel and the layer-by-layer progressive partition type air passing channels, the gravity center change in the walking process is reasonably utilized in the walking process of a user every time, the air output is large through pressure air supply, and the comfort level is higher.

Description

technical field [0001] The invention relates to the application field of polymer materials, in particular to comfortable foamed EVA slippers and a manufacturing process. Background technique [0002] In order to increase the comfort and elasticity of the slippers, the midsole of the slippers is generally made of a relatively soft primary foamed EVA material, and then bonded together with the outsole made of rubber. Due to the different materials used in the outsole, this This kind of bonding is more difficult, so some heat treatment is required when the EVA midsole is coated with glue, but this process may cause the EVA midsole to expand and contract, which cannot be well matched with the outsole, and its firmness is not high. It is easy to cause degumming. [0003] Human feet are rich in sweat glands and acupuncture points. I wear leather shoes and sneakers all day, and my feet have a fever. The inside of the shoes is wet, prone to germs and odors. And it can also cause...

And it can also cause rheumatism, many foot-related diseases and physical discomfort. Therefore, especially at home, a pair of comfortable slippers is needed for ten minutes, especially on hot days, and the soles of the feet will still produce sweat indoors. There are many medical shoes with airbags on the market, most of which use hollow airbags to set elastic parts such as springs to realize the air in and out of the airbags, and the breathing air through the airbags will blow the gas with medicines to the feet. However, this kind of footwear design More elastic parts are needed to assist, so that materials with different hardness are embedded in the soles, and the comfort is reduced, especially the metal springs are also dangerous to a certain extent. Not strong
