Abstract
A pressure sensor for an electric pressure cooker comprises a cylinder barrel with a lower opening, a piston, a pressure spring and a potentiometer. The piston and the cylinder barrel are in sliding fit with each other and are sealed by liquid and gas; one end of the pressure spring matches with the piston; the other end of the pressure spring matches with an ejector plate of the cylinder barrel; the piston drives the potentiometer; and a cylinder barrel wall between the piston and the ejector plate of the cylinder barrel is provided with an extreme pressure relief hole. As the structure is adopted, when pressure in the cooker rises, the piston moves upwardly, and electric signals of a resistor are transmitted to a control device of the electric pressure cooker. When a set pressure requirement is met, the control device powers off the electric pressure cooker, heating is stopped, and energy resources are saved. Even if the potentiometer is damaged, the extreme pressure relief hole relieves pressure, cooker explosion can be avoided, and potential safety hazards can be eliminated.

Background technology
Present prior art, a kind of pressure cooker is provided with pressure limiting valve at pot cover, and when reaching certain pressure in the pot, pressure limiting valve prevents the generation of quick-fried pot phenomenon with pressure release, the pressure signal in the pot can not be sent to control device.
Summary of the invention
The objective of the invention is: the pressure transducer that provides a kind of electric pressure cooking saucepan to use, it can to control device, prevent quick-fried pot by electrical signal transfer with the pressure in the pot, eliminates safe hidden trouble.
The present invention is achieved in that the pressure transducer that a kind of electric pressure cooking saucepan is used, and it comprises having under shed cylinder barrel, piston, pressure spring and potentiometer;
Piston and cylinder barrel are slidingly matched and the liquid hermetic seal, and pressure spring one end cooperates with piston, the other end cooperates with the top board of cylinder barrel; The piston actuated potentiometer, the cylinder barrel wall between piston and the cylinder barrel top board has limit relief hole.
The pressure transducer that described a kind of electric pressure cooking saucepan is used, its special character is: described potentiometer comprises two resistor disc, two resistor discs are in line and be arranged in parallel, the axis that two resistor discs are parallel to cylinder barrel is arranged in the cylinder barrel, resistor disc and cylinder barrel insulation, piston is as the connecting line of two resistor discs.
The pressure transducer that described a kind of electric pressure cooking saucepan is used, its special character is: described potentiometer comprises a resistor disc, the axis that resistor disc is parallel to cylinder barrel is arranged in the cylinder barrel, resistor disc and cylinder barrel insulation, piston and cylinder barrel are as conductor.
The pressure transducer that described a kind of electric pressure cooking saucepan is used, its special character is: top land is provided with on the top cover of spring base, cylinder barrel spring base is set, and pressure spring one end is provided with on the spring base of piston, the other end is arranged on the spring base of cylinder barrel.
The pressure transducer that a kind of electric pressure cooking saucepan of the present invention is used, owing to adopt such structure, the pressure in pot rises, then piston moves up, and the resistor electrical signal transfer is to the control device of electric pressure cooking saucepan, when the pressure that reaches setting requires, the control device outage stops heating, energy savings; Even if potentiometer damages, quick-fried pot phenomenon can not appear in the pressure release of limit relief hole yet, eliminates safe hidden trouble.
