Abstract
A compression cooling system of a shoe midsole comprises mainly a main body, an air sac and an air duct. The air sac is disposed in the main body such that the air sac is corresponding in location to the heel of a shoe. Two one-way valves are disposed on predetermined portions of the air sac. The air duct has one end that is connected with one of the two one-way valves and has another end that extends to reach the upper surface of the shoe midsole. The treading and the jogging actions of the foot wearing the shoe bring about the pumping effect of the air sac, thereby generating a stream of suction to cause the air inside and outside the shoe to circulate.
Claims7
A compression cooling system of a shoe midsole comprising:
- a main body provided in a lower side thereof with a slot of a predetermined length and having a through hole extending from a front end of said slot to reach an upper surface of said main body;
- an air sac disposed in a rear segment of said main body and provided in a periphery thereof with an air admitting one-way valve and an air discharging one-way valve which are separated by an appropriate distance, with said air admitting one-way valve being in communication with said slot, and with said air discharging one-way valve being in communication with an outer surface of said main body;
- and
- an air duct disposed in said slot such that a rear end of said air duct is connected with said air admitting one-way valve and that a front end of said air duct is in communication with said through hole;
- wherein said air sac is provided respectively on an upper surface thereof and a lower surface thereof with a level surface,
- each said level surface respectively spaced slightly out from an upper and a lower surface of said main body,
- wherein said front end of said air duct can be caused to bring about a stream of suction at the time when said air sac is compressed and decompressed, with said suction being capable of drawing atmospheric air into said air sac from which said atmospheric air is then driven out via said air discharging one-way valve.
