The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of pressure detecting control device of electric pressure cooking saucepan, the pot courage, the heating board that comprise stay-warm case and interior setting thereof, the pot courage is placed on the heating board, it is characterized in that: described heating board is fixed on the bottom of stay-warm case by elasticity reset device, the below of this stay-warm case is provided with liftable elastic support and high pressure signaling switch, temperature control equipment is installed on the elastic support, and the bottom of heating board is provided with and this temperature control equipment and the movable push rod that contacts of high pressure signaling switch.
As further specifying of such scheme, the bottom of described stay-warm case also is equipped with backing plate, and elasticity reset device is fixed between heating board and the backing plate, and this elasticity reset device adopts U type spring.
The elastic support of described stay-warm case below comprises gripper shoe and goes up standing screw, spring and the set screw that is provided with, and spring housing is connected on the standing screw and is fixed in the below of gripper shoe by set screw, and temperature control equipment is installed on the gripper shoe.
The bottom of described heating board is provided with the push rod more than two, and this push rod passes stay-warm case and contacts with temperature control equipment and the activity of high pressure signaling switch.
Described temperature control equipment comprises temperature controller and temperature detect switch (TDS), the external control circuit that sends signal prompt of this temperature controller.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts pot courage and heating board to be fixed on the bottom of backing plate and stay-warm case by U type spring, the pressure that steam produces, can act on the U type spring by inner bag and heat-generating disc and cause its strain, the result of its strain causes that heating board and inner bag move down simultaneously, touch temperature detect switch (TDS), cause temperature controller thermometric surface temperature because conduction of heat and fast lifting, make its disconnection send a signal, this signal can be used as the caution of pressure, has produced pressure in the prompting user pot; Fall when steam pressure can be reduced to float-controlled valve, U type spring can reset thereupon, and closed again its breaks owing to the heat conduction reduces to make temperature controller thermometric surface temperature, develops a signal, and this signal can be used as does not have the prompting of pressing.
2, the utility model connects control circuit by temperature controller, sends the signal prompt user in real time, makes the user can therefrom learn the atmospheric pressure state that pot is inner, and is safe, practical.

The specific embodiment
As Fig. 1～shown in Figure 4, the pressure detecting control device of a kind of electric pressure cooking saucepan of the utility model, the pot courage 2, the heating board 3 that comprise stay-warm case 1 and interior setting thereof, pot courage 2 is placed on the heating board 3, heating board 3 is fixed on the bottom of stay-warm case 1 by elasticity reset device 4, the below of this stay-warm case 1 is provided with liftable elastic support 5 and high pressure signaling switch 6, and protractor 7 is installed on the elastic support 5, the external control circuit that sends signal prompt of this temperature controller.The bottom of heating board 3 is provided with push rod 8-1 that contact with 7 activities of this protractor and the push rod 8-2 that contact with 6 activities of high pressure signaling switch.Elastic support 5 comprises gripper shoe 5-1 and goes up standing screw 5-2, spring 5-3 and the set screw 5-4 that is provided with, spring 5-3 is socketed on that standing screw 5-2 goes up and is fixed in the below of gripper shoe 5-1 by set screw 5-4, and temperature control equipment 7 is installed on the gripper shoe 5-1.The bottom of stay-warm case 1 can also be equipped with backing plate 9 in case of necessity, and elasticity reset device 4 is fixed between heating board 3 and stay-warm case bottom or the backing plate 9, and this elasticity reset device 7 adopts U type spring.The bottom of heating board 3 is provided with push rod 8-1, the 8-2 more than two, and this push rod 8-1 passes stay-warm case 1 and contacts with temperature control equipment 7 activities, and push rod 8-2 passes stay-warm case 1 and contacts with 6 activities of high pressure signaling switch.
In the use, after the heating board energising, liquid in the heating kettle produces steam pressure, since pot cover fastening on stay-warm case, pot courage and heating board then are fixed on the bottom of backing plate and stay-warm case by U type spring, the pressure that steam produces can act on the U type spring by inner bag and heat-generating disc and causes its strain, and the result of its strain causes that heating board and inner bag move down simultaneously.When being displaced to certain degree, the push rod that heating board stretches out can touch temperature detect switch (TDS) earlier, because heat is accelerated rapidly at short notice by the conduction meeting of metal, cause temperature controller to disconnect, send a signal, be equipped with suitable circuit control, the caution that can send pressure has produced pressure in the prompting user pot.Along with the lifting of pressure, the contact of high pressure signaling switch also can disconnect subsequently, cooperates corresponding control circuit again, thereby disconnects the power supply that leads to heating board, stops heating.After stopping heating, steam pressure can reduce, U type spring can reset thereupon, after push rod that heating board stretches out leaves the contact of pressure signal switch, the power supply that leads to heating board is connected once more, from and can make and produce a pressure in the pot, so circulation just can make the interior pressure of pot be controlled within the certain high pressure range and low pressure range.Because the push rod one direct sum temperature controller of the effect heating board of spring closely contacts, guarantee that temperature controller is the state that disconnects during this time.After heat cycles finishes, when the pot internal gas pressure reduces to safe scope, push rod one direct sum temperature controller separately, temperature can descend gradually and cause that temperature controller is closed again, control circuit can send signal prompt user pressure and fall to uncap and get food.
