This invention relates to the field of garment processing technology, specifically providing a drying device designed to solve the problem of lint filters often not being installed correctly. To address this, the drying device of this invention includes a drying duct and a lint filter. The drying duct has an insertion port, through which the lint filter is inserted. A blocking and positioning structure is located on the inner wall of the drying duct, away from the insertion port, and this structure abuts against the lint filter. By using the blocking and positioning structure within the drying duct, the user can push the lint filter forward along the duct until it abuts against the blocking and positioning structure, at which point it can no longer be pushed. This indicates that the lint filter has been installed in the designated position, thus preventing improper installation.
