AI Technical Summary
The existing rice cooker's drain switch structure is prone to accumulating dirt, making it difficult to clean, and the top rod structure is prone to jamming, posing hygiene and reliability issues.
The modular design of the sealing pipe, lifting mechanism and three-way valve is adopted. The gear-rack drive is used instead of the wedge block drive to enhance the sealing and disassembly, prevent dirt from seeping into the pot body and ensure smooth and stable drainage.
It achieves convenient cleaning and stable drainage through independent drainage channels, avoids dirt accumulation and blockage, and improves the hygiene and service life of the product.
