The specific embodiment

As shown in Figure 1, the utility model mainly is made up of air pressure conversion thrust part, motivation transfer motion part, folding lid security, tap changer part etc., air pressure conversion thrust part mainly is an air pressure switching valve (1), and air pressure switching valve (1) is made up of valve body, spool, nut, silica gel leather cup, red plastic cap.Silica gel leather cup (23) is equipped with in valve body (22) bottom, spool (24) is housed in the valve body (22), spool (24) is provided with red plastic cap (25), and the hole of red plastic cap (25) and insulating plastic pipe lid (21) cooperates, and nut (28) cooperates with valve body (22) and is fastened on the pot cover (21).When boosting in the pot, leather cup (23) and spool (24) pressurized make progress and rise promotion lever (2) work, and be with to press in the pot when showing when red plastic cap (25) rises and do not uncap, and can hand-reset when spool (24) hair fastener.

As Fig. 1,2,3,4, motivation transfer motion part shown in 5 is by lever (2), push rod (3), push rod (5), push rod (26) is formed, lever (2) is by the moulding of 1mm stainless steel bending ram, there is a seat supports centre, two ends dash microscler aperture, lever (2) rotates and depresses push rod (3) when air pressure switching valve (1) rises, push rod (3) is that aluminium bar processes, the upper end has a boss to make the submissile spring abutment, the upper end penetrates the long aperture of lever (2), pot aperture of insulating plastic pipe lid (29) is passed in the lower end, reset by little spring, push rod (5) is the aluminium rod member of upper end with a wide boss, the aperture of tongue piece (9) is pushed down in the lower end, when the pot internal gas pressure during greater than preset pressure power spread out of through lever (2) at air pressure switching valve (1), push rod (3), when push rod (5) is depressed tongue piece (9), resetting is resetted connecting rod (12) pull-up by pressure spring (11), and when pot pressure reached 0.02Kpa, the spool (24) of air pressure switching valve (1) rises eliminated the interval of each drive disk assembly.

As shown in Figure 2, the folding security is made up of push rod (26), semicircle axle (8), torsion spring (27), and push rod (26) is the aluminum component that the upper end has semicircle, and the lower end is connected with cranking arm of semicircle axle (8), and can relatively rotate.When lid does not put in place or do not close when covering, semicircle axle (8) rotates an angle and depresses tongue piece (9) under the effect of torsion spring (27), as shown in Figure 7.This moment can not normal heating as button can't be held tongue piece (9) by lower magnet (6).Close lid when putting in place push rod (26) when the screwing of insulating plastic pipe lid (29), be depressed, make semicircle axle (8) rotate to the operating position, but electric pressure cooking saucepan switch normal engagement, as shown in Figure 6.The security of uncapping is finished by a push rod (3) and a pot upper end plastic housing (4), and when in the pot during no air pressure, as shown in Figure 8, push rod (3) is in reset mode, can normally uncap.Have pressure in pot, as shown in Figure 9, push rod (3) is in depressed state, is blocked by push rod (3) and the hole in the pot upper end plastic housing (4) when uncapping, and can't uncap, and reaches safety and uncaps, the purpose of protection personal safety.

As shown in Figure 1, tap changer partly is made up of support (15), support (7), tongue piece (9), pressure spring frame (16), pressure spring (17), reset tension spring (11), two block pressur plates (14), button (19), connecting rod (12), eccentric wheel (13), coupling spindle (30), adjusting pressuring knob (10) etc., support (15), pressure spring frame (16), connecting rod (12) and two block pressur plates (14) are riveted together by two rivet work, and pressure spring frame (16) can move up and down under the effect of eccentric wheel (13) and pressure spring (17).Connecting rod (12) upper end folder one magnet (6), button (19) is with connecting rod (12) to move together downwards in external force (people's control is pressed), magnet (6) and tongue piece (9) are held, as shown in Figure 3, be loaded on compressing tablet (20) on the connecting rod (12) and leave the fine motion contact of the switch of heating (18), this moment, electric pressure cooking saucepan began the energising heating.When pot inner pressure greater than preset pressure, push rod (5) is with tongue piece (9) pressure, magnet (6) can't hold tongue piece (9), connecting rod (12) takeoffs under the effect of reset tension spring (11), the compressing tablet (20) that is loaded on the connecting rod (12) is pushed down the switch of heating (18), disconnects heating power supply, as shown in Figure 5.Regulate the pulling force that adjusting pressuring knob (10) changes pressure spring (17), can change push rod (5) and push the power of tongue piece (9) open, thus the control pot inner pressure, but realize the pressure-adjusting type purpose of control automatically.
