[0035] The cover plate 2 is further provided with a glue groove 23. The glue groove 23 is arranged on the side of the cover plate 2 close to the film face sticker 1. The glue groove 23 is filled with glue. The glue groove 23 provides space for the glue, avoiding the glue from arching at the connection between the film face sticker 1 and the cover plate 2, affecting the connection effect between the film face sticker 1 and the cover plate 2 and the flatness of the film face sticker 1. The glue enhances the connection strength between the film face sticker 1 and the cover plate 2, and at the same time, the glue can fill the small gap between the film face sticker 1 and the cover plate 2, forming a continuous sealing layer to prevent the penetration of gas, liquid or solid particles. The cooperation between the glue in the glue groove 23 and the glue sticking surface of the film face sticker 1 realizes double waterproof protection, which can more effectively prevent water from penetrating. Even if one of the glue groove 23 or the glue sticking surface fails, the other one can still play a role, ensuring the waterproof effect and protecting the waterproof performance of the electric rice cooker control structure.

[0036] Please refer to Figure 1 The components on the circuit board 3 are surrounded by the glue groove 23. The components on the circuit board 3 are surrounded by the glue groove 23. The glue groove 23 is arranged in a ring shape, and the stress of the impact can be evenly dispersed along the circumferential direction of the ring when the electric rice cooker control structure is impacted by external force, avoiding the stress from being too concentrated and causing the rapid tearing of the bonding surface. This stress dispersion feature helps to enhance the reliability and durability of the bonding.
