An apparatus for heating hot-compress eye masks by using a steam medium, relating to the technical field of human body hot-compress physiotherapy. The apparatus is provided with a first inner cavity (2) and a second inner cavity (6). Multiple steam hot-compress eye masks (5) are placed on a movable support (4) in the first inner cavity (2) side by side. A stream generating device body (7) for providing the first inner cavity (2) with steam and the like are provided in the second inner cavity (6). When the steam hot-compress eye masks (5) are heated with steam, the high-temperature steam effectively kills bacteria attached to the steam hot-compress eye masks (5), so that bacterial infection of the steam hot-compress eye masks (5) can be effectively avoided. In the process of heating the steam hot-compress eye masks (5) with steam, when a part of steam comes in contact with the steam hot-compress eye masks (5), the steam becomes water drops that are attached to the surfaces and deep layers of the hot-compress eye masks, and warm moisture can supplement moisture for dried eyes of a user. Heat storage bodies (5.2) are further provided in the steam hot-compress eye masks (5). In a high-temperature heating process, more heat is stored in the heat storage bodies (5.2), so that service time of the steam hot-compress eye masks (5) is prolonged. The steam hot-compress eye masks (5) can also be used repeatedly, thereby saving expenses for the user.
