The purpose of this utility model just is to overcome the deficiencies in the prior art, provide a kind of pressure regulation precision height, simple in structure, cost is low, the convenient electric pressure cooking saucepan pressure regulation pressurizer that uses.
The purpose of this utility model realizes in the following way:
This electric pressure cooking saucepan pressure regulation pressurizer, it is characterized in that: comprise pressure displacement touch device 14, adjust and amplify lever 13, spring leaf 12, adjustment screw mandrel 11, flash switch 10, involute adjusting device 5, spring leaf 12, adjust screw mandrel 11, flash switch 10, be screwed adjusting and amplify on the lever 13, involute adjusting device 5 lower ends are by screw and adjust and amplify lever 13 and link to each other.
The purpose of this utility model also can realize in the following way:
Described involute adjusting device 5 comprises that also the inside and outside support 1,4 of portable plate, portable plate 2, rivet cover 3, driving lever 6, adjusting lever 7, inner support brace 8, portable plate connect support 9, involute adjustment dish 5 is fixed in the inside and outside support 1,4 of portable plate by screw, driving lever 6 is vertically fixed on the portable plate 2, involute adjusting device 5 upper ends are fixed on pot body one side, and the lower end is amplified bar 13 with adjustment and linked to each other.
Described electric pressure cooking saucepan pressure regulation pressurizer is characterized in that: described flash switch 10 is the fine setting flash switch.
Described electric pressure cooking saucepan pressure regulation pressurizer, it is characterized in that: described pressure displacement signal touch pole 14 comprises touch pole, bar cover, buffer spring, fixed cover, touch pole is enclosed within the bar cover, and buffer spring is enclosed within bar cover outer bottom, and fixed cover is enclosed within the outer top of bar cover.
Adjust to amplify lever 13 and extend to across bottom of pot body and be fixed on the bottom of pot body opposite side from pot body one side, pressure displacement signal touch pole 14 upper ends are fixed on the electric heating plate middle part that is positioned at bottom of pot body, and the lower end is relative with adjustment screw mandrel 11.
Electric pressure cooking saucepan of the present utility model pressure regulation pressurizer, owing to be provided with and adjust amplification lever and pressure displacement signal touch device, adjust electric pressure cooking saucepan pressure is to make the adjustment that is fixed with flash switch and adjusts screw mandrel 11 amplify lever 13 by adjustment involute adjustment dish to move up and down, just adjusted the distance of 11 of pressure displacement signal touch pole 14 and adjustment screw mandrels, realize the pressure regulation of electric pressure cooking saucepan, therefore the advantage that is compared with prior art had is:
1, adopt double-contact fine setting flash switch, the fine setting flash switch can be adjusted and be fixed on a best flashes a little, and it flashes precision height, reliable operation.
2, the pressure displacement signal is to amplify the back by spring leaf 12 to touch flash switch, thereby has improved electric pressure cooking saucepan pressurize precision.
3, adopt involute adjustment dish to adjust, and amplify bar 13 and amplify control by adjusting, the linearity adjustment that has realized amplifying has guaranteed reliability and the stability adjusted.
4, pressure displacement signal touch pole 14 has adopted buffer unit, when electric pressure cooking saucepan because during improper factor build-up of pressure displacement signal touch pole 14 amounts of moving down excessive when reaching the sealing ring sealing limit (be pot inner pressure), after having guaranteed unusual eliminating, this pressure regulation pressurizer still can operate as normal.
Fig. 1 is the utility model electric pressure cooking saucepan pressure regulation pressure-holding apparatus structure schematic diagram;
Fig. 2 is that the utility model electric pressure cooking saucepan amplifies lever plan structure schematic diagram with the adjustment of pressure regulation pressurizer;
Fig. 3 is that the utility model electric pressure cooking saucepan coils right TV structure schematic diagram with the adjustment of pressure regulation pressurizer involute;
Fig. 1-the 3rd, the utility model electric pressure cooking saucepan most preferred embodiment of pressure regulation pressurizer is described further with the pressure regulation pressurizer electric pressure cooking saucepan of the present utility model below in conjunction with accompanying drawing:
As Figure 1-3, wherein: 1 motion bar inner support, 2 portable plates, 3 rivets overlap the 5 involute adjustment of 4 motion bar support arms and coil 6 driving levers, 7 adjusting levers, 8 inner support braces, 9 portable plates connection support, 10 flash switch, 11 adjustment screw mandrels, 12 spring leafs, 13 adjustment amplification levers, 14 pressure displacement signal touch poles.
Make an electric pressure cooking saucepan pressure regulation pressurizer as shown in Figure 1, manufacturing process is as follows: at first involute adjusting device, pressure displacement signal touch device are made, again flash switch 10, adjustment screw mandrel 11, spring leaf 12 are fixed on to adjust and amplify on the lever 13, again involute adjusting device and adjustment amplification lever are linked together.Course of action is as follows: when need regulation voltage power pot inner pressure, by adjusting involute adjustment dish the adjustment amplification lever 13 that is fixed with flash switch 10 and adjusts screw mandrel 11 is moved up and down, and adjusted pressure displacement signal touch pole 14 and adjusted the distance of 11 of screw mandrels, realize the pressure regulation of electric pressure cooking saucepan.Pressure displacement signal touch pole 14 moves down when pot inner pressure increases, and when reaching the adjustment pressure spot, touches spring leaf 12, and spring leaf 12 amplifies this displacement signal and touches flash switch 10, thereby off voltage power pot heater element power supply stops heating; When pot inner pressure reduced, pressure displacement signal touch pole 14 moved up, when pot inner pressure is lower than the adjustment force value, by adjusting screw mandrel 11 retracting spring sheets 12, spring leaf 12 amplifies this displacement signal and makes the flash switch closing of contact, and the electric pressure cooking saucepan heater element gets electric, begins heating; When pot inner pressure rises to adjustment pressure, repeat above process again, thereby being stabilized in, the electric pressure cooking saucepan internal pressure adjusts on the force value.
