Description
Technical Field
[0001] The utility model relates to the technical field of lighting, and more specifically, it relates to a lamp socket structure. Background Art
[0002] In modern kitchen appliances, air fryers and ovens are widely popular due to their high efficiency and convenience. These devices cook food in a closed space, effectively locking in the nutrition and flavor of the food. However, this sealing also brings some inconvenience, that is, it is difficult for users to directly monitor the cooking process of the food. To solve this problem, a lighting system is integrated inside the device, and the cooking space is illuminated by a built-in lighting lamp, enabling users to clearly observe key cooking details such as the color change and even heat distribution of the food, so as to more accurately control the cooking progress and ensure that each dish can achieve the best cooking effect.
[0003] However, the lighting lamp design widely used in current air fryers and ovens has certain defects. Specifically, the fixing and conductive methods between the lamp beads and the ceramic base are relatively single. Usually, only two connecting pieces are relied on for clamping and fixing, and at the same time, electrical contact between the lamp bead contacts and the connecting pieces is ensured. This makes the connecting pieces need to simultaneously meet the requirements of providing stable mechanical support and ensuring good electrical connection ability. However, it is often difficult to perfectly balance these two aspects. During actual use, due to vibrations, temperature changes, or material aging caused by long-term use, it is very easy to occur that the contact between the lamp beads and the connecting pieces is poor, or the lamp beads are loose or even fall off, which not only affects the user experience but also may cause potential safety hazards; and in existing lighting lamps, the lamp beads usually contact the connecting pieces of the lamp socket in the form of conductive sheets in a face-to-face manner. If the flatness of the contact surface between the two is not good, it is very easy to occur poor contact.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model
