Moreover, the connecting block 3 is formed with the mounting groove, and the part cover of pivot 21 in the mounting groove is equipped with hinge spring, and hinge spring both ends are formed with first torque arm and second torque arm respectively, and first torque arm is fixed with connecting block 3, and second torque arm and lid 2 are fixed to make lid 2 have the function of uncapping automatically.

Referring to fig. 7 to 9, in order to switch the fixing and separating states of the cover 2 and the base 1, the support ring of the base 1 is provided with a rotatable cover-removing switch 4, the cover-removing switch 4 and the connecting block 3 are provided with mutually matched locking structures, and the locking structures lock the cover-removing switch 4 and the connecting block 3 with each other to relatively fix the base 1 and the cover 2. And the cover-removing switch 4 is pressed to rotate, so that the locking mechanism is separated, and the base 1 and the cover 2 can be removed.

Wherein, in order to make the uncapping switch 4 rotatable, uncapping switch 4 is formed with axis body 41, opens the rotatory hole 11 that has the symmetry to set up on the support ring of base 1, and rotatory hole 11 supplies the axis body 41 both ends to peg graft to uncapping switch 4 rotates around the axis of rotation of axis body 41. And a guide notch 12 extending to the edge of the base 1 is formed at the opening of the rotation hole 11, and the shaft body 41 is inserted into the rotation hole 11 along the guide notch 12.

Wherein, the locking structure can select different structures according to the condition, wherein preferred is:

the locking structure comprises a buckle 42 arranged on the cover-removing switch 4 and a bayonet 32 arranged on the connecting block 3, and the bayonet 32 is used for the buckle 42 to buckle in so as to fix the connecting block 3 and the cover-removing switch 4.

Specifically, the buckle 42 includes a connecting arm 421 located on one side of the shaft body 41, a fixture block 422 is formed at one end of the connecting arm 421 away from the shaft body 41, and the fixture block 422 is used for being buckled with the bayonet 32.

As the lid release switch 4 rotates, the catch 42 swings with the lid release switch 4. When the cover-removing switch 4 rotates in the forward direction, the buckle 42 is buckled with the bayonet 32, and the connecting block 3 is fixed on the base 1. When the cover-removing switch 4 rotates reversely, the buckle 42 and the bayonet 32 are buckled and separated, so that the connecting block 3 and the base 1 are separated.

The specific rotation of the forward rotation and the reverse rotation depends on the position of the latch 42 relative to the bayonet 32. The latch 42 is located on the counterclockwise side of the bayonet 32, and the forward rotation is clockwise rotation, and the reverse rotation is counterclockwise rotation. Of course, the latch 42 may be located on the clockwise side of the bayonet 32, and the forward rotation is counterclockwise rotation, and the reverse rotation is clockwise rotation.

In order to facilitate the rotation of the lid-removing switch 4, the opening 13 is provided on the support ring of the base 1, the lid-removing switch 4 is provided with the key portion 43, the key portion 43 is exposed from the opening 13, and the key portion 43 is pressed to rotate the lid-removing switch 4. In addition, for saving labor, the button part 43 is located on the side of the shaft body 41 away from the locking structure, and the moment arm T1 from the locking structure to the shaft body 41 is shorter than the moment arm T2 from the button part 43 to the shaft body 41, so as to play a role in relieving the pressing force; but the moment arm T1 cannot be too short, otherwise the press portion needs to be rotated more degrees to disengage the lid release catch 42 and the button catch 42, with an optimum moment arm ratio of 0.3< T1/T2<1 being evaluated.

In order to reset the cover-removing switch 4, an elastic member is clamped between the button part 43 of the cover-removing switch 4 and the support ring of the base 1, and the elastic member drives the cover-removing switch 4 to rotate, so that the buckle 42 swings and is buckled with the bayonet 32. Specifically, the elastic member is a return spring 5. In order to install the return spring 5, a boss is formed on the support ring of the base 1, a cross-shaped positioning rib is formed on the cover-removing switch 4, one end of the return spring 5 is sleeved outside the boss, and the other end of the return spring is sleeved outside the positioning rib, so that the return spring 5 is installed and fixed. The return spring 5 is disposed inside the key part 43 so that the key part 43 is divided.

And the end of the buckle 42, that is, the end of the latch 422, is formed with a guide angle 423, the side wall of the connecting block 3 is abutted by the guide angle 423, and the tangential component force of the pressure applied to the guide angle 423 by the connecting block 3 causes the cover removing switch 4 to press the return spring 5 and rotate, so that the connecting block 3 is installed in place. Then, the lid-removing switch 4 is driven to return by the return spring 5, and the latch 42 is engaged with the bayonet 32 to prevent the lid body 2 and the base 1 from being separated. And the connecting block 3 comprises a lug, the bayonet 42 is arranged on the side wall of the lug, and the bottom wall of the lug is used for abutting against the guide angle 423

Besides the locking structure, the locking structure can also adopt clamping hooks respectively arranged on the cover-removing switch 4 and the connecting block 3, and the two clamping hooks are mutually hooked to realize fixation; it is also possible to change the positions of the catch 42 and the bayonet 32, to place the catch 42 on the connector block 3, and to place the catch 42 on the switch. Other parts such as hooks and loops, etc., will not be described in detail.

In addition, the connection is not stable only by the locking structure, the supporting ring of the base 1 is further formed with a baffle 14 opposite to the cover-removing switch 4, side plates 15 are formed on two sides of the baffle 14, and a socket 16 is formed between the baffle 14 and the two side plates 15, and the socket 16 is used for the connection block 3 to be inserted. The socket 16 and the locking mechanism are thus arranged around the connecting piece 3, ensuring a secure connection. The side plate 15 is further provided with an escape opening 15113, and the escape opening 15113 is used for escaping from the rotating shaft 21.

The utility model also discloses a household appliance which comprises the flip shell. Specifically, the household appliance can be a shell in which a cover body 2 and a base 1 are hinged, such as an electric cooker, a micro-pressure cooker, an electric kettle, an electric soup cooker and the like.
