In order to separate the latch tongue 34 from the fixed engaging portion 31 to unlock the door, an unlocking mechanism 4 is provided. Referring to fig. 2 to 6, the unlocking mechanism 4 includes a pressing structure 41 and a pushing mechanism 42 disposed on the cover 2, the pressing structure 41 is rotatably connected to the cover 2, the pressing structure 41 abuts against the pushing mechanism 42, and when the cover is opened, the pressing structure 41 is pressed, the pressing structure 41 drives the pushing mechanism 42 to push the rotating member 33 to rotate, so that the latch 34 is far away from the fixed engaging portion 31 and separated from the fixed engaging portion 31, so as to allow the cover 2 to be opened upwards. Through the pressing operation, the pressing structure 41 drives the pushing mechanism 42, and the pushing mechanism 42 pushes the rotating member 33 to rotate, so that the latch 34 is separated from the fixed engaging portion 31 and separated from the fixed engaging portion 31, and the lid 2 is unlocked and can rotate. In the invention, when unlocking, the unlocking is realized by pressing the pressing structure 41 downwards, and the pressing unlocking mode more conforms to the force application habit of human fingers and has better hand feeling.

The pressing structure 41 includes a rotating shaft 411 coupled to the cover 2, and a pressing portion 412 and a pushing portion 413 extending from the rotating shaft 411 and perpendicular to an axis of the rotating shaft 411, the pushing portion 413 abuts against an end of the first slider 421 away from the second slider 422, the pressing portion 412 is pressed, and the pushing portion 413 rotates with the rotating shaft 411 and moves the first slider 421 from the normal position to the unlocking position. That is, the pressing structure 41 is similar to a lever, and when the pressing portion 412 is pressed, the pushing portion 413 rotates to push the first sliding member 421 to move to the unlocking position, so as to achieve unlocking. In this embodiment, the rotating shaft portion 411, the pressing portion 412 and the pushing portion 413 are integrated, and a rib is further provided between the pressing portion 412 and the pushing portion 413 to increase the strength of the pressing structure 41. The pressing portion 412 and the pushing portion 413 are rod-shaped, such as square rod-shaped, and may be disposed along a line or may form an angle, the angle is 90-150 °, and in this embodiment, the angle between the pressing portion 412 and the pushing portion 413 is 120 °.

In order to keep the latch tongue 34 and the rotating part 33 in contact with each other and move relatively, referring to fig. 1, 4 and 7, the movable fastening assembly further includes an elastic pulling member 35, both ends of the elastic pulling member 35 are respectively connected to the latch tongue 34 and the rotating part 33, and the latch tongue 34 and the rotating part 33 are tightly contacted with each other by the elastic force of the elastic pulling member 35, so that when the rotating part 33 rotates away from the fixed fastening part 31, the latch tongue 34 is pulled together by the elastic force of the elastic pulling member 35 to move, and the latch tongue 34 retracts into the slot; when the rotating member 33 rotates to approach the fixed engaging portion 31, the contact end directly pushes the latch 34 to move upward, so as to approach the fixed engaging portion 31, and further engage with the fixed engaging portion 31 to lock the cover 2. Specifically, the locking tongue 34 is provided with a first protrusion 341, the rotating member 33 is provided with a second protrusion 334, and two ends of the elastic pulling member 35 are respectively connected to the first protrusion 341 and the second protrusion 334. The elastic traction piece 35 is a tension spring or an elastic belt or an elastic rubber ring.

In this embodiment, referring to fig. 1, the shaft connecting portion 21 is further provided with a third elastic member 5, two ends of the third elastic member 5 abut against the lid 2 and the kettle body, and an elastic force toward the lid opening direction is applied to the lid 2. The elastic force of the third elastic member 5 is continuously present, and when the cover 2 is closed, the elastic force is present, and when the latch 34 is separated from the fixed engaging portion 31 to be unlocked after the pressing structure 41 is pressed down, the elastic force of the third elastic member 5 is automatically opened upward at the cover 2 without manually opening the cover. The third elastic member 5 is a torsion spring.
