Description

Breathing shoes

Technical Field

The invention relates to a shoe, in particular to a pair of breathing shoes.

Background

The prior breathing shoe structure generally comprises a sole and a shoe body, an inner shoe pad is arranged on the upper surface of the sole, an elastic air bag is arranged at the heel of the inner shoe pad, one-way air valves are arranged at the front end and the rear end of the elastic air bag, the air inlet end of the one-way air valve at the front end is connected with an air inlet pipe, the air outlet end of the one-way air valve at the front end is communicated with the inner cavity of the elastic air bag through a connecting pipe, the air inlet end of the air inlet pipe is arranged at the front sole of the sole, the air inlet end of the one-way air valve at the rear end is communicated with the inner cavity of the elastic air bag, the other end of the one-way air valve at the rear end is communicated with the outside of the sole, a fixing groove for the elastic air bag to be clamped in is arranged at the heel of the sole, a rear groove for the one-way air valve at the rear end is arranged at the, in the process of treading by a user, the elastic air bag is easy to incline in the fixing groove by the inclined treading force of the traditional breathing shoe, so that the phenomenon that the elastic air bag is easy to damage is caused, the automatic recovery speed is reduced, the breathing and ventilation effects are lost, and meanwhile, as the service lives of the sole and the shoe body are usually more than 2-3 years, most of the shoes which are damaged firstly are the elastic air bag, the breathing effect caused by the elasticity is lost, and the integral use experience and the service life are influenced; according to the existing breathing shoe structure, aiming at soles with different lengths, the elastic air bags are positioned at heels of the soles, so that the soles with different lengths are caused, the lengths of the fixing grooves of the soles and the rear grooves connected with the outside of the soles are different, and the one-way air valves adopted in the existing breathing shoes cannot adjust corresponding lengths to adapt to the rear grooves with different lengths, so that the one-way air valves with different lengths are required to be prepared in the actual production of the breathing shoes, more production lines and molds are required to be arranged, the production cost is greatly increased, and the production procedure is more complicated; the stability of the valve core in the valve body of the existing one-way air valve is insufficient, so that the valve core is deviated in the breathing process, air leaks, the normal breathing efficiency of the breathing shoes is greatly reduced, the use comfort of the breathing shoes is reduced, the existing one-way air valve is poor in sealing performance, the air leakage is further easy to occur, the breathing amplitude of the breathing shoes is further reduced, and the use experience is extremely poor; because its respiratory effect of traditional breathing shoes is realized by the reply of elasticity gasbag entirely, and the compound department that the reply of elasticity gasbag need drive in shoes pad and sole and the shoes pad links together, with shoes pad and sole part upwards jack up, long-term load has further aggravated like this and is lifting the foot in-process, the loss that the elasticity gasbag replied, thereby further reduced the life of elasticity gasbag, the junction part of sole and shoes pad also can be because of lasting about extrusion effect elastic fatigue, it is more and more slow and the resilience height is low more to kick-back, the wearing comfort has been reduced, need improve from this.
