[0002] At present, most health pots are mainly used for steaming and boiling. The structure is generally that a steam duct is provided in the pot, a steam outlet is opened in the steam duct, a sleeve is provided outside the steam duct, a steam channel is formed between the steam duct and the sleeve, and the steam is guided to the bottom of the pot through the steam channel; however, this structure has limitations and its functions are relatively simple.
