The embodiment of the invention discloses a dehumidifier which comprises a ventilation shell, a fan and a sealing base, wherein the ventilation shell can bear a desiccant, and the desiccant can absorb moisture in air; the ventilation shell is connected with one end of an air recovery shell, and a fan which drives the air to flow to contact the desiccant borne by the ventilation shell when operating is installed on the air recovery shell; and the sealing base is connected with the other end of the air recovery shell and is provided with a soft edge which can cling to the inner wall of a shoe and seal the shoe. In the embodiment, by adding the fan in the dehumidifier, peripheral air is driven to fully contact the desiccant, thereby accelerating the moisture absorption speed of the desiccantand enhancing the moisture absorption function. In addition, by adding the sealing base, the shoe is sealed and a sealed space is formed, and therefore, a range of dry air can be shortened within thespace of the shoe, and the dehumidification efficiency is enhanced. Further, because the shoe is sealed with the sealing base, the dehumidification range of the dehumidifier is limited within the range of a shoe frame, and the dehumidification efficiency is enhanced.
