Description

technical field [0001] The invention relates to a pressure cooker for kitchen utensils, in particular to a pressure cooker with visible button opening and closing. Background technique [0002] The pressure cooker used for sealed cooking, the pressure cooker generally cooks food under the pressure inside the pot of 4 ~ 110KPa. Of course, the pot body and the pot cover are sealed by a sealing ring, and the two are tightly fastened. This just has a problem how to open the pot lid or close the lid. Naturally, the method for opening the pressure cooker pot lid or closing the high-pressure lid first tries to open the pot lid or close the lid when the air pressure in the pot is at first trying to communicate with the normal pressure of the outer atmospheric pressure. Some pressure cookers on the market have unclear instructions on the opening and closing lid. During use, the lid and the pot are in a half-open state, which may cause safety accidents due to the inability to fasten...

AI Technical Summary

Problems solved by technology

Some pressure cookers on the market do not have clear indications on the opening and closing lids. During use, the lid and the pot are likely to be half-opened and closed, causing the pot and the lid to fail to buckle and cause safety accidents.
