<p>The present invention relates to a check valve for shoes with an excellent ventilation function, which comprises: a body which is hollow inside and provided with an inlet for introducing air at an end; a communicating plate provided inside the body to close inner part of the body, and having a plurality of communicating holes to allow air introduced from the inlet of the body to flow; a soft opening and closing member having a cone-shaped opening and closing plate at an end to envelop and close the communicating holes and where a fixing body, which is elongated lengthily from a center of the opening and closing plate to the other end, is forcefully inserted and fixed into an insertion hole provided at a center of the communicating plate; a cover coupled and fixed onto the other end of the body to close the other end of the body, and having a plurality of outlet holes to release air introduced through the inlet hole of the body; and a connecting member coupling the body and the cover with ease. The present invention determines opening and closing of the air-flowing communicating hole in a way that the opening and closing plate of the cone-shaped opening and closing member is turned over or turned back to normal under an influence of flowing air, thereby extending a useful life of a product compared to an existing structure of a releasing piece of the check valve for shoes. The present invention also exhibits an excellent ventilation function of the shoes for a long period of time and thus provides pleasant environment for a user of the shoes. In addition, the opening and closing member, which determines opening and closing of the communicating hole where air flows through, can be mass-produced through an injection. Therefore, the present invention has effects of enhancing productivity of the product as well as improving the quality of the products by having remarkably low failure rate of the product during a manufacturing process.</p> |
