Embodiment Construction

[0025] refer to Figure 1 to Figure 8 , the present invention is an air bag ventilation structure and its insole and shoes. The airbag ventilation structure has a first airbag 1 and a second airbag 2, and a pressure relief valve 3, a differential pressure valve 4 and a gas damper 5 can be arranged between the first airbag 1 and the second airbag 2 in pairs. Different states of motion are thereby realized and corresponding energy feedbacks are produced. The pressure relief valve 3, the differential pressure valve 4, the gas damper 5 and the first airbag 1 and the second airbag 2 are all bonded or made integrally, so that the cost is low and the manufacture is convenient.

[0026] Specific reference Figure 4 , the pressure relief valve 3 includes a pipe body 61, a stepped valve 62 contracted in the pipe body 61, a reciprocating piston 63, a spring 64 is arranged between the piston 63 and the pipe body 61, and the spring 64 is used to reset the piston 63 , The piston 63 block...

Abstract

An air bag ventilation structure, comprising a first air bag (1) and a second air bag (2). The first air bag (1) and the second airbag (2) may be communicated with each other by means of any two of a pressure relief valve (3), a differential pressure valve (4), and an air damper (6). Also disclosed is an insole or a midsole comprising the air bag ventilation structure. The air bag ventilation structure can produce corresponding energy feedback along with the change of a motion state.

Description

technical field [0001] The invention relates to the field of shoes, in particular to an air bag ventilation structure, an insole and shoes. Background technique [0002] At present, in footwear products, air cushions are widely used due to their cushioning function. Common air cushions are inflated and pressurized air cushions to provide better energy feedback effects. The energy feedback of the air cushion increases due to the increase in the impact of motion, when the amount of motion impact is large. Excessive energy feedback will increase foot and leg discomfort and even cause injury; when the amount of exercise impact is small, the rebound provided is insufficient, affecting exercise performance. Contents of the invention [0003] The object of the present invention is to provide an airbag ventilation structure capable of generating corresponding energy feedback as the movement state changes, as well as its insole and shoes. [0004] The technical scheme that the p...
