Fig. 1 is that the overall structure of the utility model electric pressure cooking saucepan is cutd open and shown schematic diagram;
Fig. 2 is that the pressure regulation pressure-holding apparatus structure of the utility model electric pressure cooking saucepan cuts open and shows schematic diagram;
Fig. 3 is the pressure regulation pressurizer involute adjustment dish structural representation of the utility model electric pressure cooking saucepan;
Fig. 1-the 3rd, the most preferred embodiment of the utility model electric pressure cooking saucepan, wherein: it is 14 O-ring seals, 15 inner pot covers, 16 outer pot cover 17 outer pot housings that 1 inner pan body, 2 electric heating plates, 3 outer pan bodies, 4 combination cylinder springs, 5 shells 6 adjustment amplification levers, 7 spring leafs, 8 adjustment screw mandrels, 9 signal displacement touch poles, 10 flash switch, 11 portable plates, 12 involute adjustment dishes 13 are carried.
Below in conjunction with accompanying drawing 1-3 the utility model electric pressure cooking saucepan is described further:
As Figure 1-3: make a playscript with stage directions utility model electric pressure cooking saucepan, the inner pot cover 15 that has O-ring seal 14 is placed on the inner pan body 1, electric heating plate 2 is close in inner pan body 1 bottom, an available buffer displacement signal touch pole 9 is fixed in electric heating plate 2 centers, electric heating plate 2 peripheries are equipped with a circle combination cylinder spring 4, face toward the adjustment screw mandrel 8 that is used to touch flash switch 10 on the pressure regulation pressurizer under the displacement signal touch pole 9, outer pan body 3 one sides are provided with involute adjustment dish 12, the portable plate 11 of involute regulator be fixed with flash switch 10 and adjust screw mandrel 8, the adjustment amplification bar 6 that amplifies spring leaf 7 links to each other, the contact of flashing of flash switch 10 is serially connected in the electrical heating elements circuit, " outage " and " getting " of control electrical heating elements.Elasticity pot button is fixed on the inner pot cover 15, and inner pot cover covers on inner pan body 1, and the inner pot cover outer is sleeved in the groove of O-ring seal 14.
The course of work is as follows: connect power supply, select a cooking food pressure by adjusting involute adjustment dish earlier, even being fixed with the adjustment amplification bar of flash switch and adjustment screw mandrel moves up and down, just adjusted the distance between pressure displacement signal touch pole and adjustment screw mandrel, the size of the distance that the displacement signal touch pole moves down depends on the size of cooking pressure in the inner pan body, and promptly electric heating plate bears pressure and overcomes combination cylinder compression spring force with it and move down apart from being directly proportional.Pressure displacement signal touch pole moves down when pot inner pressure increases, reach and touch spring leaf when adjusting pressure spot, spring leaf amplifies this pressure displacement signal and the shake-up flash switch, thereby off voltage power pot electric heating plate power supply, stop heating, when stopping to heat in a period of time pot inner pressure and reduce, pressure displacement signal touch pole moves up, when pot inner pressure is lower than adjusted value, by adjusting screw mandrel retracting spring sheet, spring leaf amplifies this displacement signal and touches flash switch makes its closing of contact, thereby the electric pressure cooking saucepan electric heating plate must be established the beginning heating by cable, when pot inner pressure rises to adjusted value, repeat above process again, thereby realized the pressure regulation and the pressure holding function of electric pressure cooking saucepan.
