[0001] The utility model relates to the technical field of ovens, in particular to an oven auxiliary door closing mechanism. Background Art

[0002] An oven, also known as a drying oven or a drying cabinet, is a device used for heating and drying materials. It uses the heat generated by electric heating elements or other heat sources to heat the items placed inside the cabinet through air convection or radiation, so as to achieve the purposes of removing moisture, drying, curing, heat treatment or disinfection, etc. Ovens are widely used in many fields such as industrial production, laboratory research, food processing and healthcare. Their designs are diverse, from simple constant temperature ovens to complex programmable multi-stage temperature control ovens, to meet the specific processing requirements of different materials or products. Ovens are easy to operate and have precise temperature control, and are important and indispensable devices in modern production and scientific research.
