1. A latching structure for a cooking device, wherein the cooking device comprises a casing and a door body, the door body being engaged with the casing in an openable and closable manner, the latching structure comprising:
a flipping member rotatably disposed on the casing, the flipping member being configured to drive, in response to being triggered to rotate to a door-opening position, a hook of the door body to be disengaged from a limiting portion of the casing;
a first restoring member connected to the flipping member and the casing respectively, the first restoring member being configured to provide the flipping member with a first restoring force for allowing the flipping member to rotate towards a non-triggered position;
a restricting member movably disposed on the casing between a first position in which the restricting member blocks the flipping member from rotating towards the door-opening position and a second position in which the restricting member avoids a rotation of the flipping member; and
a second restoring member connected to the restricting member and the casing respectively, the second restoring member being configured to provide the restricting member with a second restoring force for allowing the restricting member to move towards the first position,
wherein the latching structure is configured such that under the first restoring force, a restoring speed at which the flipping member rotates towards the non-triggered position is greater than a restoring speed at which the restricting member moves from the second position towards the first position, to allow the restricting member to avoid restoration of the flipping member.
