Description

Technical Field

[0001] The utility model belongs to the technical field of pressure cookers, in particular to a pressure cooker cover and a pressure cooker. Background Art

[0002] A pressure cooker is a common cooking vessel. Its principle is to increase the pressure inside the pot to cook food. During the cooking process, when the pressure inside the pressure cooker reaches the working pressure, the weight part of the weight assembly will be lifted to exhaust gas, so that the pressure inside the pot is maintained within a certain range, thereby achieving the purpose of high-pressure cooking. In existing pressure cooker lids, the weight assembly usually uses a seesaw to adjust its relative height in the form of a lever. The weight assembly installed in the steam hole is usually set in the steam discharge chamber, and the adjustment structure for operating the seesaw is set in the lid cavity of the pressure cooker lid. The steam discharge chamber and the lid cavity are connected by a through hole, and the seesaw is swingably connected to the weight assembly through the through hole. However, since the seesaw is swingably placed in the through hole, it is easy for food steam generated in the steam discharge chamber to enter the lid cavity of the pressure cooker lid through the through hole. Over time, the lid cavity is prone to accumulation of bacteria and odors, which makes it difficult to clean. The pressure cooker lid is not hygienic enough and the user experience is not ideal.
