The electric pressure cooker shown in figures 1-5 comprises a cooker body 1, a cooker cover 2 hinged on the cooker body 1, and an inner cooker 3 placed inside the cooker body 1. The cooker cover 2 is provided with a first buckle piece 41 used for being connected with the inner cooker 3, a second buckle piece 42 used for being connected with the cooker body 1, a handle 43 acting on the first buckle piece 41, and a cover opening button 44 acting on the second buckle piece 42. In addition, the pot cover 2 is further provided with a clamping plate 45 and a baffle 46 which are linked with the handle 43, and a locking component which can be clamped with the clamping plate 45. When the lid 2 and the inner pot 3 are in the snap-fit connection state, the baffle 46 limits the lid-opening button 44 to act on the second snap-fit element 42, so that the lid-opening button 44 cannot release the snap-fit connection state of the lid 2 and the pot body 1. When the buckling connection state of the pot cover 2 and the inner pot 3 is released, the clamping plate 45 moves to a position corresponding to the locking component. When the cooker cover 2 is separated from the inner cooker 3, the lock catch component is clamped with the clamping plate 45. When the pot cover 2 contacts with the inner pot 3, the inner pot 3 acts on the locking component and releases the clamping relation with the clamping plate 45.

The technical scheme recorded above relates to an electric pressure cooker, a first buckle piece 41 is arranged in a cooker cover 2 of the electric pressure cooker and is used for being connected with an inner cooker 3, and a second buckle piece 42 is arranged and is used for being connected with a cooker body 1; the first latch 41 is driven by a handle 43, the second latch 42 is driven by a lid-opening button 44, and a baffle 46 and a catch plate 45 are linked on the handle 43. When the lid 2 and the inner pan 3 are in the snap-fit connection state (i.e. the first snap-fit member 41 is in the snap-fit state) under the driving action of the handle 43, the lid 2 and the pan body 1 should be in the snap-fit connection state. However, in the conventional electric pressure cooker, the cover 2 and the inner cooker 3 are in a buckling connection state, and the cover 2 is bounced by touching the cover opening button 44 through misoperation, so that great potential safety hazards exist. However, in the present embodiment, the stopper 46 restricts the lid opening button 44 from acting on the second locking member 42 in the closed state of the lid 2, so that the above-mentioned safety accident does not occur even if the lid opening button 44 is touched by an erroneous operation. Further, when the snap-fit connection state of the pot cover 2 and the inner pot 3 is released, the handle 43 moves the snap plate 45 to the position corresponding to the locking component. When the snap connection state is released but the lid 2 and the inner pot 3 are not yet separated (i.e., contact), the inner pot 3 acts on (withstands) the locking assembly. When the cooker cover 2 is further turned up to be separated from the inner cooker 3 in the state, the locking assembly can be clamped with the clamping plate 45. Because cardboard 45 and handle 43 are linked mutually, consequently handle 43 angle is restricted, and further first buckle 41 can not produce the dislocation with interior pot 3, has avoided normally closing the lid and seriously influences user experience's problem.

The middle part of the cover closing buckle is arranged in the cooker cover 2, the lower end part of the cover closing buckle is connected to the output end of a first spring 51, and the first spring presses the cover closing buckle to a middle ring buckle 49. The lid opening button 44 is connected to the lid closing button through a lid opening connector 52, an input end of the lid opening connector 52 is disposed below the lid opening button 44, and a second spring 53 for driving the lid opening button 44 to reset is disposed below the lid opening connector 52. The output end of the lid opening connector 52 acts on the upper end of the lid closing buckle. When the lid 2 is in the snap-fit connection with the inner pot 3, the stopper 46 is under the lid opening button 44 and restricts the downward movement of the lid opening button 44.

The latch assembly includes a latch 54, and a latch spring 55 for driving the latch 54 to move longitudinally. The lock catch 54 is provided with a hook part 56 which is formed by turning downwards, and the clamping plate 45 is provided with a hook groove matched with the hook part. The lower end of the lock catch 54 is provided with an inner cover plate assembly, when the pot cover 2 contacts the inner pot 3, the inner pot 3 jacks up the inner cover plate assembly to drive the lock catch 54 to move upwards, and the clamping relation between the lock catch 54 and the clamping plate 45 is released.
