[0002] An oven, also known as a baking oven or drying oven, uses heating elements in a sealed space to generate high temperatures, which are then used to bake food through heat conduction. Compared to open flame grilling, ovens avoid direct contact with the heat source and produce no oil fumes, making them suitable for cooking whole chickens, thick steaks, cakes, bread, and other foods. However, current ovens often lack a corresponding limit protection structure for their temperature control switch knobs. When using an oven in a confined space such as a campervan, or when children accidentally operate it, the temperature control switch knob may be accidentally turned on, posing a safety risk. Therefore, we have proposed a temperature control switch limit device to solve the above problems. Utility Model Content
