The specific embodiment
Below in conjunction with accompanying drawing and embodiment the specific embodiment of the utility model is further described.
Like Fig. 1, shown in Figure 5, a kind of pressure cooker lid of pressure release safely and fast comprises push rod 1, pressure limiting valve 2 and the link gear 3 of uncapping; Pot cover is provided with guiding mechanism 4; Guiding mechanism 4 is provided with spacing muscle 41, and the link gear 3 of uncapping is provided with hollow convex column 32, said projection 32 be provided with pot cover guiding mechanism 4 on spacing muscle 41 corresponding grooves 33; Guiding mechanism 4 matches with hollow convex column 32 on the link gear 3 of uncapping; The link gear 3 of uncapping is provided with the inclined-plane 31 that work moves downward, and the right-hand member of push rod 1 is provided with the inclined-plane 11 that matches and move horizontally with the link gear inclined-plane 31 of uncapping, and the relative pressure limiting valve 2 of the front end of push rod 1 is provided with; In the present embodiment, guiding mechanism 4 is a projection; Pot cover is provided with strip hole 42, and the below of pot cover is provided with spiral cover 7, and spiral cover 7 is connected with pot cover; Spiral cover 7 is provided with projection 71; The right-hand member of link gear 3 of uncapping is provided with breach 35, and the projection 71 on the spiral cover 7 is sleeved in the said breach 35, and rotates in strip hole 42 along the pot cover circumferencial direction.In the present embodiment, the top of the link gear 3 of uncapping is provided with the boss 32 of hollow, and pot cover handle (not shown) is sleeved on the boss 32 of the link gear of uncapping.When rotation pot cover handle, the right-hand member that drives the interlinked mechanism 3 of uncapping is along the pot cover circular motion, thereby the projection 71 that drives on the spiral cover 7 rotates in pot cover strip hole 42, thereby realizes the folding lid of pot cover.
Like Fig. 2, shown in Figure 4, when pot cover is screwed into when uncapping state, the groove 33 on the hollow convex column 32 of link gear 3 belows of uncapping, corresponding with the spacing muscle 41 on the guiding mechanism 4 on the pot cover.When pushing the pot cover handle downwards; Spacing muscle 41 on the guiding mechanism is installed in the groove 33 of the link gear of uncapping, and the inclined-plane 31 of link gear 3 of uncapping this moment contacts with inclined-plane 11 on the push rod 1, and push rod 1 is moved horizontally; And promote to move to pressure limiting valve 2 directions; When weight in the pressure limiting valve 21 and pressure limiting valve blast pipe 22 no longer seal, the steam in the pressure cooker is discharged from blast pipe 22, realize quick pressure releasing.As shown in Figure 3; When stopping to push when uncapping link gear 3; The reposition element 5 that link gear 3 bottoms are provided with of the uncapping link gear 3 that promotes to uncap resets, and the reposition element 6 of push rod 1 front end setting promotes push rods 1 and resets, the weights 21 in the pressure limiting valve 2 since the effect of gravity seal with blast pipe 22.In order to guarantee that push rod 1 can do setting movement on pot cover, pot cover is provided with ram seat 12, and push rod 1 is nested with horizontal movement in the ram seat 12 on pot cover.
When being screwed into, closes when covering state by pot cover; The uncap position of the spacing muscle 41 on groove 33 and the guiding mechanism 4 on the link gear 3 is not corresponding; Even push the pot cover handle this moment downwards, the inclined-plane 31 of the link gear 3 of uncapping can not contact with inclined-plane 11 on the push rod 1, also just can not promote push rod 1 and move horizontally; Pressure limiting valve 2 is in sealing state all the time, thereby reaches purpose of safety.In order to guarantee the sealing of push rod 1 and pressure limiting valve bonnet, pressure limiting valve bonnet lateral wall is provided with sealing ring 8, and is as shown in Figure 1.
The utility model can be widely used on various pressure cookers and the electric pressure cooking saucepan cooking apparatus.
