Specific embodiment
Embodiment 1
As shown in Figure 1-3, the present invention provides a kind of anti-seal circle, the pot of neglected loading (is not shown in the figure, in pot body) in liner
Lid comprising (" lower section " here refers to for upper cover 1, the locking closure 2 being disposed below and the sealing ring 4 below the locking closure
Sealing ring is not proper below locking closure in the lower recess of locking closure, and sealing ring upper end is embedded in locking closure lower part
Groove, lower end abut liner, form sealing), the locking closure 2 is located at the lower inner of the upper cover 1 and can be opposite around its axis
The upper cover 1 is moved and (is preferably rotated), to open or close to pot cover, and the sealing ring 4 is located under the locking closure 2
Side, the liner are located at 4 lower section of sealing ring, and (liner upper end is connected under sealing ring when pot cover connects with pot body cooperation
End), and being provided on the locking closure 2 can be with the locking structure 3 of 1 mating reaction of upper cover；
The lower end of the locking structure 3 abuts with the sealing ring 4, (can not be shown in figure by the sealing ring 4 and liner
Out, belong to the pot body part of pressure cooker) jack up, the locking closure 2 can move (preferably rotation) relative to the upper cover 1 at this time,
Locking closure relative to upper cover rotation i.e. relieve locking structure between upper cover and locking closure locking, being capable of correct folding lid；When
When neglected loading sealing ring 4 and/or liner, the locking structure 3 cannot be jacked up, the locking closure cannot be relative to the upper cover at this time
Movement (preferably rotates), and locking closure can not rotate relative to upper cover and live upper cover and locking closure by locking structure locking, make
The two lid between cannot rotate relatively, i.e. at this time can not correct folding lid.By judge locking closure whether can relatively on
Lid movement (preferably rotate) to judge sealing ring and/or liner whether neglected loading.
Locking structure is just to play the role of jack-up under the accumulative action of sealing ring and liner, closing lid in place when,
Locking structure top is got on by the collective effect of sealing ring and liner, realizes uncap at this time, if neglected loading sealing ring and liner
In any, at this time can not be by locking structure top, the upper cover in pot cover, therebetween can not relative motion by locking closure locking.
By be provided on locking closure can be with the locking structure of the upper cover mating reaction；The lower end of locking structure with it is close
Seal abutting can be jacked up jointly by sealing ring and liner, locking closure can be moved relative to upper cover, when neglected loading sealing ring and/or liner,
Locking structure cannot be jacked up, locking closure cannot be moved relative to upper cover, be enabled to only in correctly installation sealing ring and liner
Locking closure could be enabled to generate movement relative to upper cover after in place, could enable pot cover or even electric heating appliance normally work
Make, locking closure is locked up that mechanism is stuck relative to upper cover, can not work normally when otherwise any in neglected loading sealing ring and liner, therefore
Can be effectively detected out sealing ring and/or liner whether neglected loading the case where, improve pressure cooker normal work safety and
Reliability.Above structure of the present invention can also detect sealing ring and/or whether liner size is less than normal, when sealing ring is wherein appointed with liner
If one size is less than normal, locking structure can not be jacked up by sealing ring and liner jointly, i.e., can not carried out always at this time just
True folding lid, it can sealing ring is effectively detected out and whether any size of liner is less than normal.
Preferably, the locking structure include the first position limiting structure for being set to its radial outside, it is upper in the upper cover 1
The effect of capable of matching with first position limiting structure is additionally provided in its radially inner side to carry out the second of rotation locking to locking closure 2
Position limiting structure.Radially inner side is arranged through the first position limiting structure being arranged in locking structure radial outside and on locking closure second
Position limiting structure effectively can make neglected loading seal effectively to the position-limiting action for forming circumferential direction between locking closure and upper cover
Locking structure rises so that locking closure phase after locking structure, which is fallen, when circle prevents locking closure from rotating relative to upper cover, sealing ring is correctly installed
Upper cover can be rotated, thus accurate accurate detection whether having effectively achieved to sealing ring installation (whether neglected loading).
Preferably, first position limiting structure is the bulge-structure 6 radially protruded, and (bulge-structure 6 is arranged
In the radial outside of the movable part 9), second position limiting structure is the sunk structure 7 being radially recessed；Or, institute
Stating the first position limiting structure is the sunk structure being radially recessed, second position limiting structure be radially protrude it is convex
Play structure.This is the specific structure type of two position limiting structures matched of the invention, passes through the cooperation of protrusion and recess
Form can be effectively to snap-in function be formed, to complete locking effect and unlock work between the two between locking closure and upper cover
With.
Preferably, it is provided in the upper cover 1 and allows and guide the locking structure 3 in the groove wherein to make rotating motion
5 (preferably arc grooves).By be arranged groove the rotary motion of locking structure can be played receiving and while supporting function,
It can also play the role of guidance and guiding to its rotational motion, it is preferable that the radian of the arc groove is less than or equal to 360 degree.
Embodiment 2

It is further preferred that the diameter of the first protrusion is simultaneously also greater than the diameter of the receiving hole 8, so that first
Insertion section is unlikely to deviate from downwards from receiving hole, plays the role of the limit moved downward to the first insertion section.Certain first
Protrusion cannot be located at the bottom of the first insertion section, to influence to carry out clamping lock to locking closure in the first insertion section insertion receiving hole
Effect.
Preferably, in the periphery of first insertion section 91, positioned at first protrusion 911 and the movable fixed part
Section between 92, is also arranged with the first elastomeric element 93, and 93 upper end of the first elastomeric element is resisted against the movable fixed part 92
Upper and lower end is resisted against on first protrusion 911.By being located at the first protrusion in the first insertion section periphery and activity is fixed
The mode of the first elastomeric element is arranged in portion's diameter, can by the movable fixed part that is fixed on locking closure, via the first elastic portion
Part (preferably spring), the first protrusion to the first insertion section generate downward elastic thrust (because spring upper end abutment end it is motionless,
Lower end is movable, once spring move upwards compressed, if will generate downward elastic restoring force), effectively further make
In neglected loading sealing ring movable part can move downward and protrude into receiving hole, to reach to rotation side between locking closure and upper cover
To effective locking, be notified in time user, be notified to sealing ring neglected loading real-time condition.
Preferably, the second protrusion 912 radially protruded is additionally provided in the upper end of first insertion section 91,
The diameter of second protrusion 912 is greater than the diameter of the limit hole 921.Pass through the upper end setting in the first insertion section
The mode of second protrusion, can effectively make the first insertion section be unlikely to deviate from when moving downward the movable fixed part,
To play the role of the limit moved downward to first insertion section.It is further preferred that second protrusion and described the
Seperated ground processing sets up, is fixed on the upper of first insertion section for the second protrusion by way of screw between one insertion section
End.
