[0002] The problem of foot odor has been around for a long time, especially it has always been one of the main reasons that bother sports enthusiasts. During exercise, the feet will sweat, and because the shoes are not breathable, a lot of odor will be stored inside the shoes. When the odor comes out from the inside of the shoes in crowded places, the person involved will be extremely embarrassed, especially after exercise. The traditional method is to wash the feet frequently or add anti-odor pads, but the effect is not ideal, and the odor will still affect other people, so it cannot meet the needs of users.

[0003] Therefore, it is urgent to improve the soles with deodorizing function to solve the above-mentioned problems. Summary of the invention

[0004] The purpose of the present invention is to provide a sole with deodorizing function and a method thereof. The odor inside the shoe body is sucked into the interior of the air storage bin by a gas exhaust device and sealed inside the air storage bin, squeezed through a gas purification device for purification, and then discharged to the outside of the shoe body through the arch groove of the sole. Therefore, fresh air is sucked into the interior of the shoe body, and then purified by the gas purification device and discharged. Therefore, the circulation of air inside the shoe body can be promoted, and the comfort can be improved while reducing the emission of odor.

[0030] 1. The odor inside the shoe body is drawn into the air storage bin by the gas discharge device and sealed inside the air storage bin, squeezed through the gas purification device for purification, and then discharged to the outside of the shoe body through the arch groove of the sole. Therefore, fresh air is sucked into the shoe body, and then purified by the gas purification device before being discharged. Therefore, it can promote the circulation of air inside the shoe body, improve comfort and reduce odor emissions.
