Technical Field

[0001] The utility model belongs to the technical field of electric heating equipment, and in particular relates to a maintenance mechanism for an electric heating module of a heating box. Background Art

[0002] Heating boxes are a common heating device used in various industrial applications for heating and drying, often serving as heating equipment in production lines or large machinery. They include built-in overcurrent, overheating, and overload protection circuits. They offer a compact size, low cost, excellent performance, high reliability, and ease of use.

[0003] Currently, heating boxes on the market consist of a box body and a heating module. The heating module is typically installed within the box body. Due to frequent use, the heating module is a consumable component and requires maintenance or replacement. However, existing heating module replacement or maintenance requires workers to bend over, which can be harmful to workers if prolonged. Furthermore, increasing the height of the heating module within the box body makes it difficult to remove the module for maintenance, impacting maintenance efficiency and reducing safety.
