Ventilated Shoe with Heel

Abstract

This invention relates to a shoe with hygienic fixture, more particularly to a shoe with heel having ventilation device in its sole. The invention is characterized by that the vent-slots on the sole piece gather together near the center of toes transverse line on the sole piece, and a convex air-gathering pipeline is disposed between the gather point and the air intake check valve. The purpose of the invention is to design a ventilated shoe, which can increase ventilating quantity and keep good ventilation effect. Compared with the prior art, the advantages of the present invention are large ventilating quantity, longer using life, and no air leaking when using.

1 . A ventilated shoe with heel, comprising several vent-slots on a sole, an air intake check valve, an air exhaust check valve and an air chamber located in a concave space on the heel, wherein the vent-slots on the sole piece gather together near the center of a toes transverse line on the sole, a convex air-gathering pipeline is disposed between the gather point and the air intake check valve. 
     
     
         2 . The ventilated shoe with heel of  claim 1 , wherein the outer surface of the convex air-gather pipeline is connected smoothly with the sole piece through approach ramp. 
     
     
         3 . The ventilated shoe with heel of  claim 2 , wherein a latex pipe is sleeved on the pipe connection between the air intake check valve and the air chamber. 
     
     
         4 . The ventilated shoe with heel of  claim 3 , wherein the top surface of the air chamber is of convex shape. 
     
     
         5 . The ventilated shoe with heel of  claim 4 , wherein the annular surface of the air chamber and the annular surface of the heel are on a same plane. 
     
     
         6 . The ventilated shoe with heel of  claim 5 , wherein the exhaust port and intake port parallel with each other, a convex L-shaped installation groove is set on the sole piece between the exhaust port and the outside of sole piece, the exhaust port is connected to the exhaust valve through a soft pipe mounted on the L-shaped installation groove, and the exhaust valve is opened to atmosphere. 
     
     
         7 . The ventilated shoe with heel of  claim 6 , wherein there is a moveable soft underlay inside the soft pipe.
