Embodiment 4

Preferably, the present embodiment provides a kind of pressure cookers, and compared with Example 3, as described in Fig. 3 and Fig. 8, rotary shaft 121 It further include washer 1213.Wherein, the end of main shaft 1211 is arranged in washer 1213, as shown in fig. 5A to 5C, sets on washer 1213 It is equipped with through-hole 1214, so that washer 1213 is sleeved in connecting shaft 1212.Wherein, the connector on washer 1213 and pot cover ontology It is mutually clamped by snap-in structure, so that fixing piece can be in its natural state (not under the action of by external force) relative to pot cover ontology It is maintained at first position or the second position.Preferably, washer is silica gel material.

If fixing piece is in first position relative to pot cover ontology, uncapped state is turned to by closing lid state in pressure cooker When, fixing piece is removably locked directly on buckle structure.If fixing piece is in second relative to pot cover ontology When setting, when pressure cooker turns to uncapped state by closing lid state, buckle structure cannot directly lock the fixing piece.

Specifically, as shown in Figure 10, fixing piece is in first position relative to pot cover ontology 11, that is, the fixation of fixing piece Portion 122 is arranged close to the inner circle of pot cover ontology 11, and the rotary shaft 121 of fixing piece is arranged far from the inner circle of pot cover ontology 11.Such as figure After pot cover shown in 10 and pot body closing lid, then when turning to uncapped state by closing lid state, fixing piece is directly with dismountable side Formula is locked on buckle structure.

As shown in figure 11, fixing piece is in the second position relative to pot cover ontology 11, that is, the fixed part 122 of fixing piece is remote The rotary shaft 121 of inner circle setting from pot cover ontology 11, fixing piece is arranged close to the inner circle of pot cover ontology 11.As shown in figure 12 Shown in state diagram after pot cover and pot body closing lid, when pressure cooker turns to uncapped state by closing lid state, buckle structure portion is not Fixing piece can directly be locked.

Embodiment 5

Preferably, the present embodiment provides a kind of pressure cookers, and compared with Example 4, as shown in Fig. 2, Fig. 5 A to Fig. 5 C, this reality The snap-in structure applied in example for engaging washer and connector includes: the protrusion 1215, Yi Jishe being arranged on washer 1213 Set the pit 1112 on connector 11.Wherein, pit 1112 is matched with protrusion 1215.Specifically, protrusion is two, i.e., the One protrusion and the second protrusion, wherein the first protrusion and the second protrusion are relative to connection axial symmetry.Pit is two, i.e., first is recessed Hole and second dimple, wherein the first pit and second dimple are symmetrical relative to turn hole.

Here, protrusion may also be arranged on connector, correspondingly, pit is arranged on washer.In addition, when connecting shaft includes At two, snap-in structure need to be only set on the washer to connect with one of connecting shaft.

Snap-in structure in the present embodiment is arranged to above structure, is not only simple in structure, and in its natural state steady It is qualitative preferable, so that fixing piece is maintained at first position or the second position relative to pot cover ontology.In addition, in the effect of external force Under, the engaging of snap-in structure can be overcome between pot cover ontology and fixing piece, rotate pot cover ontology relative to fixing piece.

Embodiment 6

Preferably, the present embodiment provides a kind of pressure cookers, compared with above-described embodiment, as shown in fig. 4 and 13, this implementation Buckle structure 21 in example is one for locking the card slot of fixed part on fixing piece.Wherein, it is provided on card slot for making to fix Portion slides into the import 211 in card slot along a first direction.Wherein, first direction refers to: pressure cooker is by closing lid state to uncapping When state, the direction of rotation of pot cover.If, only need to be by pot cover along opposite with first direction when the locking of disassembly fixed part and card slot Direction rotate.Bayonet 212 is provided on card slot.

Preferably, the fixed part 122 on fixing piece 12 includes first part as shown in Fig. 3, Fig. 4, Fig. 7 to Fig. 9, Figure 13 1221 and second part 1222.Wherein, first part 1221 connect with rotary shaft 1211, and the size of first part 1221 is less than The size of buckle structure upper latch notch 212.Wherein, when fixed part 122 enters in card slot, the first part of fixed part 122 is by card Mouth 212 reaches outside card slot, and second part 1222 is fastened in card slot.

Pressure cooker provided in this embodiment is not only convenient for consolidating fixing piece by the way that buckle structure is arranged to above structure Determine portion to be locked, and locking effect is good, is also convenient for removing fixed part from buckle structure.

The separate mode of pot cover and pot body in above-described embodiment has following two:

The first, as shown in Figure 10, when pressure cooker provided by the above embodiment is in closing lid state, fixing piece is relative to pot cover When ontology 11 is in first position；Under the action of protrusion and pit between washer and connector cooperate, fixing piece is in nature It is able to maintain under state in first position.When pressure cooker is rotated by closing lid state to uncapped state, fixed part on fixing piece by Gradually close to buckle structure, and slid into buckle structure by the import on buckle structure.To remove pot cover, then need to open on pot cover Gai Hou can remove pot cover by pot cover by pot cover ontology is rotated in the opposite direction with first party.

The second, as is illustrated by figs. 11 and 12, pressure cooker provided by the above embodiment is in closing lid state, fixing piece relative to When pot cover ontology 11 is in the second position；Under the action of protrusion and pit cooperation between washer and connector, fixing piece is certainly It is able to maintain under right state in the second position.Fixed part when pressure cooker is rotated by closing lid state to uncapped state, on fixing piece Buckle structure is moved closer to, still, fixed part is not corresponding with buckle structure, can not slide into buckle structure；When pressure cooker rotates When to uncapped state, directly pot cover is taken down.

In conclusion the pot cover and pot body in pressure cooker provided in an embodiment of the present invention can be connected removably, and Make pressure cooker during pot cover is opened and is fastened, improves the stationarity of pot cover rotation；And avoid the angle uncapped due to pot cover Catching phenomenon caused by degree is too big occurs.

To sum up, it will be readily appreciated by those skilled in the art that under the premise of not conflicting, above-mentioned each advantageous manner can be certainly It combined, be superimposed by ground.

The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, according to According to technical spirit any simple modification, equivalent change and modification to the above embodiments of the invention, this hair is still fallen within In the range of bright technical solution.
