A pressure cooker with a lock

Abstract

The invention relates to a pressure cooker provided with a lock. The pressure cooker comprises a cooker cover and a cooker body, wherein the cooker cover and the cooker body are in matched connection; the lock, by which the cooker cover is prevented from freely rotating along a peripheral direction of the cooker body, is arranged on the cooker body; and a matching structure, which is matched with the lock, is arranged on the cooker cover; or the lock, by which the cooker cover is prevented from freely rotating along the peripheral direction of the cooker body, is arranged on the cooker cover; and the matching structure, which is matched with the lock, is arranged on the cooker body. Furthermore, the lock comprises an ejector rod which can extend and shrink and an electromagnetic control structure. The lock and the matching structure can be matched in a mode of being mutually inserted, so that relative rotation between the cooker cover and the cooker body is limited, subsequently, the cooker cover of the pressure cooker is prevented from being accidentally opened, and especially, an accident that a child, who opens and plays the cooker cover of the pressure cover out of curiosity, gets scalded is prevented.

Description

technical field [0001] The invention relates to the technical field of pressure cookers, in particular to a pressure cooker with a lock. Background technique [0002] The pressure cooker uses a sealed cavity to steam food, with high cooking pressure and cooking temperature. During the operation of the pressure cooker or after the operation is stopped, a large amount of high-temperature water vapor will be released to release the pressure, which is very attractive to children. And pressure cooker is of a great variety in the market at present, and color is different, and it is very easy to attract children to use it as a toy. [0003] Pressure cookers currently on the market do not have a child lock function, and only use a safety lid closing device to fix the lid of the pressure cooker on the pot body. The safety lid closing device can ensure the safety of the pressure cooker during normal operation, but it cannot prevent children from opening the pressure cooker lid throu...

AI Technical Summary

Problems solved by technology

The safety lid closing device can ensure the safety of the pressure cooker during normal operation, but it cannot prevent children from opening the lid of the pressure cooker through normal operation without the attention of their parents

If the pressure inside the pot does not drop to a certain safe value at this time, dangers such as the pot lid being washed away and the high-temperature food in the pot may be easily caused; It is easy to cause scald injury to children and has a greater safety hazard
