Description
Technical field
The utility model is related to pressure cooker technical field, particularly a kind of lock cover of pressure cooker structure.
Background technology
By taking current electric pressure cooking saucepan as an example, it includes pot and pot cover, and pot inner top, which is circular layout, concavo-convex alternate
Pot tooth, pot cover inwall correspondence pot tooth is provided with button bit, by rotating pot cover so that below pot tooth of the button bit in protrusion, realizing pot cover
With lid snapping, conversely, when button bit is rotated to recessed pot tooth in company with pot cover, pot cover can be dug or open.Due to pot
Interior air pressure is uncapped dangerous property when higher, therefore, existing pressure cooker, there is a set of self-locking mechanism, self-locking mechanism include with
The air supporting valve air pressure change in pot and fluctuate, slide laterally the lock pin component being arranged in pot cover, lock pin component one end
Close to the pot tooth surface of pot, the lock pin component other end is extended at air supporting valve, under normal circumstances, if air pressure is relatively low in pot
（Safe opening air pressure）, air supporting valve will not stop lock pin component, during pot cover Unscrew, lock pin component along pot pot tooth surface from
By activity, do not influence to uncap；Conversely, when air pressure is too high in pot, air supporting valve stops lock pin component, so that lock pin component can not edge
Pot pot tooth surface is freely movable, therefore pot cover can not rotate, so that can not uncap.Certainly, the shape of simply theory described above
State, but actually still there is certain potential safety hazard in the structure, because being certainly existed between air supporting valve and lock pin component certain
Diastema（If no diastema air supporting valve will be stuck）Even if, it is anticyclonic in pot in the case of, if acting on pot cover
Rotation uncap active force it is larger when, lock pin component can overcome the resistance of air supporting valve, and change the state of air supporting valve, just can be this
It is unfavorable for uncapping in the state of uncapping, so as to bring huge potential safety hazard, it is therefore desirable to be improved the structure.
