Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure cooking of special dietary food, and provides a sealing mechanism for a high-pressure cooking device for special dietary food, which can effectively ensure the quality of special dietary food and extend the service life of a sealing ring. Background Art

[0002] A high-pressure steaming device for special dietary foods is a device designed specifically for preparing special dietary foods. Combining the features of a pressure cooker and a retort, it can efficiently and quickly prepare special dietary foods while preserving the nutrients in the ingredients. Existing high-pressure steaming devices for special dietary foods operate similarly to conventional pressure cookers: high-pressure steam heats the inner pot of a double-layered pot, transferring heat to the inner pot during the heating process. The continued heating of the ingredients within the pot generates steam. Due to the high-pressure sealing mechanism in the lid, the steam continuously builds up inside the pot, creating pressure. Once the pressure reaches a certain level, a safety valve on the lid automatically releases the pressure, ensuring a safe and controllable cooking process for special dietary foods. Existing high-pressure sealing mechanisms typically utilize a sealing ring on the lid and a snap-on mechanism located on the edge of the lid. Over time, these structures can create a seal between the pot and lid, creating a pressure seal. During installation, the lid can easily wear against the sealing ring, resulting in poor sealing and compromised quality of the special dietary foods. Utility Model Content
