When electric pressure cooking saucepan began to heat and boils to the pressure that produces steam in pot body, the strain thin slice was subjected to the steam pressure effect and the dilatancy that makes progress; At this moment, touching Contact Transmission bar also promotes the switch reed of flash switch, and the contact that is connected with heater circuit of flash switch is disengaged, thereby cuts off heater circuit.
Can advance to regulate to the time of flashing of flash switch by adjustment screw, thereby reach the purpose of vapor pressure in the control electric pressure cooking saucepan.
Steam pressure reduces in electric pressure cooking saucepan, and the deflection of strain thin slice reduces, and flash switch resets, and the contact that be connected with heater circuit this moment contacts, and heater circuit is connected and continued to heat; Realize the purpose of the interior steam pressure of control electric pressure cooking saucepan automatically thus.
Compared with prior art, advantage of the present utility model is: 1. overall structure is compact simply again, automatically the control action sensitivity; 2. use with easy to maintenance, and have reliability and service life preferably.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a kind of prior art constructions schematic diagram;
The specific embodiment
Embodiment describes in further detail utility model below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show an embodiment of the utility model pressure controller of electric pressure cooker.It comprises
Flash switch 1 is fixed on the bracing frame 3 by screw 4; Bracing frame 3 is welded on the pot cover 2.Pedestal 5 is a metal processing piece, is provided with sealing ring 8, strain thin slice 6, clamping piece 7 in it; Sealing ring 8, strain thin slice 6, clamping piece 7 adopt clinching method to be connected and fixed one with pedestal 5.Strain thin slice 6 upper fixed connection one has the clamping piece 7 of centre bore 71; Placing one in the centre bore 71 of clamping piece can the free Contact Transmission bar 9 of play up and down.One end of Contact Transmission bar 9 contacts with the switch reed 11 of flash switch, and the other end of Contact Transmission bar 9 contacts with strain thin slice 6.
Fixed connection method between pedestal 5 and strain thin slice 6, clamping piece 7, the sealing ring 8 also can adopt threaded connection method or adopt adhering method.
Pedestal 5 also can adopt threaded connection method with the fixed connection method of pot cover 2; Pedestal 5 also can adopt adhering method with the fixed connection method of pot cover 2.
The geometry of pedestal 5 is set to circle; It is polygon-shaped also can be set to four limits, hexagon, eight limits etc.
Clamping piece 7 plays position-limiting action simultaneously, is used to prevent in the electric pressure cooking saucepan that steam pressure is too high and permanent deformations take place strain thin slice 6 that cause.
The strain thin slice is set to circular wave shape strain thin slice; Also can be set to circular tabular strain thin slice by the strain thin slice; Also can be set to circular tabular and its bottom have "+" font, "-" font or the like the strain thin slice of various ways reinforcement; The strain thin slice of above-described various ways all carried out effectively test and validation.
Strain thin slice 6 is provided with a shrinkage pool in the center with respect to Contact Transmission bar 9, to help the location that contacts between Contact Transmission bar 9 and the strain thin slice 6.
