The specific embodiment

Below in conjunction with accompanying drawing 1, the utility model is described in further detail to accompanying drawing 8 embodiment.

Accompanying drawing 1 to accompanying drawing 2 is stereogram and the cutaway views before the whole embodiment closing lids of the utility model.In accompanying drawing 1, connecting rod 5 is hinged with pot cover 21, connecting rod 5 is not depressed or is subject to and upwards flicks state under the elastic force effect of elastic component 64, plug 42 does not insert socket 41, when simultaneously connecting rod 5 upwards lifts or upsprings by 221 jack-up of the weight on pressure release bar 222, connecting rod 5 can be pressed partial journey downwards, and there is certain stroke distances one end that connecting rod 5 swings with pot body 1 or pot cover 21, can increase the motion remaining of pot cover 21, pot body 1 and miscellaneous part; Accompanying drawing 2 is cutaway views of accompanying drawing 1, when connecting rod 5 is lifted or while being upspring, the through hole that pin 62 in device 6 leaves pot cover 21 is put in described sealing ring leakproof, pin 62 does not have sealed circle 24 jack-up shake-up sealing ring leakproofs to put the indicator 63 on the support 61 of device 6 yet, between support 61 and pin 62, be provided with the elastic component 64 sliding to the through hole direction of crossing on pot cover 21 for drive pin 62, strengthen pin 62 and slide to the through hole direction of crossing on pot cover 21, reduce possibilities that pin 62 is stuck or other normally slide; When connecting rod 5 is pressed certain distance or whereabouts certain distance downwards, pin 62 will be through the through hole on seal groove 211, if do not place sealing ring 24 in seal groove 211, if placed sealing ring 24 in seal groove 211, thereby pin 62 will be sealed circle 24 blocking-up can not down sliding, by the pin 62 of jack-up, can be touched indicator 63, indicator 63 can provide the signal of having placed sealing ring 24 simultaneously.Indicator 63 can be mechanical type, electronic type optics, pneumatic type or other forms, and the indicator 63 providing in figure is arranged on support 61 one end away from pot cover, has placed sealing ring 24 and just just can conflict, and sends the signal of placement; Indicator 63 can be also to adopt the mode of sending signal while not placing sealing ring 24, for example at body, near one end of pot cover 21, indicator 63 is set, do not place sealing ring 24, thereby pin 62 will can contact and touch indicator 63 to 1 motion of pot body, and indicator 63 sends the signal of not placing sealing ring 24.Indicator 63 is positioning indicators 63, can show state can transform or be designed for herein, in industrial products or design, there are indicators for switching condition, fault detector, Control director, water flow indicator etc., the household electrical appliances such as the present electric cooker containing control function, soy bean milk making machine all can show its running status, and old-fashioned household electrical appliances such as smoke exhaust ventilator also have button indicator.Indicator 63 can be electronic director, and electronic director has rich and varied alerting pattern, more intuitively handy, and can control mainboard with electric pressure cooking appliance and be connected, and cost is also lower.Control device 3 accompanying drawings are not shown, and control device 3 can be with reference to control device or the system of intelligent electric cooker.The electric device 12 of electric pressure cooking appliance can be generally heater, agitating device or milling device etc., depends on the demand that electric pressure cooking appliance purposes determines.

Pot cover 21 is split-type structural with pot body 1, plug 42 is arranged on respectively on pot 21 and pot body 1 with socket 41, after pot cover 21 screws completely with pot body 1, plug 42 could insert socket 41, the loop of power supply could be communicated with, finally just can make relevant electric component or device, as control device, heater, electromechanical assembly or alarming device etc. enter duty.

In accompanying drawing, the splicing position of socket 41 and plug 42 does not show and is provided with buckle, but in technical scheme, is provided with buckle.Buckle strengthening grafting dynamics, if the buckle not in place of pegging graft just can not fasten, strengthens the stability that plug 42 is connected with socket 41, from structure, avoids pegging graft not in place.

In Fig. 1, pot cover 21 is provided with the stopper slot for limiting rod 5 swaying directions and amplitude.The direction of motion of limiting rod 5 and amplitude, reduce the infringement that improper use causes.Between simultaneously hinged plug 42 or socket 41 and stopper slot, be provided with buckle.Strengthening grafting dynamics, not in placely just can not fasten if peg graft, and the stability that reinforcement plug 42 is connected with socket 41, avoids pegging graft not in place from structure.Between connecting rod 5 and pot cover 21, can be provided with elastic component 64, described elastic component 64 is Compress Spring, and Fig. 1 and Fig. 2 do not draw; After plug 42 is extracted from socket 41, drivening rod 5 moves upward, and elastic component 64 increases the restoring force that connecting rod 5 moves upward.

Fig. 3 and Fig. 4 are the whole embodiment closing lids of the utility model but do not depress stereogram and the cutaway view of power supply.In cutaway view, show and placed sealing ring 24, but do not depress power supply, thus connecting rod 5 or the state in opening, jack-up weight 221, pin 62 does not slip into the through hole at pot cover 21 seal groove 211 places yet simultaneously.Connecting rod 5 moves in stopper slot, and amplitude and direction are subject to the restriction of stopper slot.

Fig. 5 and Fig. 6 are stereogram and the cutaway view that the whole embodiment of the utility model place sealing ring 24 closing lids.Sealed circle 24 blocking-up of pin 62 can not be to pot body 1; Indicator 63 is arranged on support 61 away from one end of pot cover 21, by the pin 62 of jack-up, is conflicted and arrives indicator 63, has placed sealing ring 24 in demonstration place seal groove 211.Connecting rod 5 moves in stopper slot, and amplitude and direction are subject to the restriction of stopper slot, and accompanying drawing shows that connecting rod 5 has been depressed, and plug 42 has inserted socket 41.

Fig. 7 and Fig. 8 are stereogram and the cutaway view that the whole embodiment of the utility model do not place sealing ring 24 closing lids; Owing to not placing sealing ring 24, thus pin 62 under elastic component 64 or Action of Gravity Field to pot body 1, pin 62 is away from indicator 63, indicator 63 does not show in pot cover that 21 have placed the signal of sealing ring 24.
