Problems solved by technology

[0005] The disadvantage of this control method is that the mechanical amplification factor of the seesaw lever mechanism is not stable enough, resulting in the displacement variation of the sealed pressure valve 12, that is, only one control signal reflects the parameter of the pressure in the pot, and it cannot be stably and accurately determined. transmitted to the magnet 14, resulting in a large control error and too few control points

The described elastic sealing cover is fixedly sealed on the hole wall of said cover lid, the described pressure driving device is placed in the elastic sealing cover, the described pressure driving device includes liner, driving bar and rotary output shaft, the described line is inlaid in the elastic sealing cover, and the described driving bar can be movably passed through side wall of liner and horizontally extended into the line interior, and the described rotary output shaft is connected with driving bar. Said invention is safe and reliable, and its control accuracy is high.

Description

technical field [0001] The invention relates to an electric pressure cooker, in particular to a pressure conversion device of the electric pressure cooker. Background technique [0002] As a kind of electric cooking utensil, the electric pressure cooker works under high pressure. In order to ensure the safety of the electric pressure cooker, the pressure in the electric pressure cooker must be controlled so that the pressure in the electric pressure cooker does not exceed a certain dangerous value. The pressure inside the pressure cooker is converted into corresponding mechanical parameters or electrical parameters, and then the feedback control of the pressure inside the cooker is completed by the relevant mechanical device or electronic circuit, which is one of the key links to finally realize the pressure control of the pressure cooker. [0003] The pressure conversion device of the traditional electric pressure cooker, such as the Chinese invention patent named "Fully Se...
