  • Touch-control deodorant device for shoes

    Abstract: This specification discloses a deodorant device installed on a shoe. The deodorant device includes a pouch having a gas outlet and at least one duct connecting from the gas outlet to the toe position inside the shoe. The pouch has the ability to elastically restore its size from contraction. As the user walks, his/her foot imposes a pressure on the pouch. The perfume or deodorant prestored inside the pouch is then ejected to prevent mold growth on the toes. It can immediately remove or decompose the bad odor inside the shoe.
