Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, and more specifically, to a drying mechanism for a dental mold cleaning machine. Background Art

[0002] After the dental mold cleaning machine cleans the dental mold, it needs to be dried by a drying mechanism. The current drying device is generally only provided with a single cavity. When in use, multiple dental molds are placed in the cavity at the same time, and heated air is introduced into the cavity to dry the dental molds. When the number of dental molds is reduced, the space of the cavity will not be reduced, and it still takes a long time to achieve the temperature increase of the entire cavity, which will waste heat; in addition, the existing drying device is generally provided with a cabinet and a cabinet door. The dental mold is placed in the cabinet. When in use, the cabinet door is closed to avoid a large amount of heat spillover, but the sealing between the cabinet door and the cabinet is poor, and a certain degree of heat spillover will still occur during use, resulting in heat loss and affecting the drying efficiency.
