In the whole cover opening process, the operation button is not needed, so that the button does not need to be arranged on the cooker cover 10 or the cooker body 20, the area of the display plate block is not occupied, the typesetting of the display content and the operation button is not influenced, the outer surface of the cooker body 20 or the cooker cover 10 is a complete surface, the integrity of the outer wall surface of the electric cooker is ensured, and the processing of the cooker cover 10 and the cooker body 20 of the electric cooker is simplified.

As shown in fig. 9, 11 and 12, the holding mechanism includes a first biasing member 51, and both ends of the first biasing member 51 are provided on the inner lid 2 and the face cover 1, respectively. For example, the first biasing member 51 is a compression spring, and both ends of the compression spring are fixed to the inner lid 2 and the face cover 1, respectively. In fig. 12, the compression spring applies a first biasing force toward the left to the face cover 1, holding the face cover 1 in the initial position shown in fig. 12 with respect to the inner lid 2.

To facilitate assembly of the first biasing member 51, as shown in FIGS. 7, 9, 11 and 12, the retaining mechanism preferably further includes a mounting seat 52 provided on the inner lid 2, and a first blocking member 11 provided on the face cover 1, as shown in FIG. 11; both ends of the first biasing member 51 are provided on the mount 52 and the first blocking member 11, respectively, and the first biasing member 51 acts on the face cover 1 by applying the first biasing force to the first blocking member 11.

For example, as shown in fig. 11 and 12, the mounting seat 52 is provided with a first mounting groove 521 with a notch facing the first blocking member 11; the first biasing member 51 has one end fitted into the first fitting groove 521 and the other end provided on the first blocking member 11 outside the notch of the first fitting groove 521. The first mounting groove 521 is provided to facilitate mounting of the first biasing member 51 to the inner cap 2.

Further preferably, as shown in fig. 12, the holding mechanism further includes a transition sleeve 53 slidably disposed on the first mounting groove 521; one end of the first biasing member 51 is embedded in the first mounting groove 521, and the other end thereof extends out of the notch of the first mounting groove 521 and is mounted in the transition sleeve 53; the transition sleeve 53 is disposed in abutment with the first blocking element 11.

Since the transition sleeve 53 is slidably disposed on the first mounting groove 521, and both ends of the first biasing member 51 are respectively fitted into the first mounting groove 521 and the transition sleeve 53, when the first biasing member 51 is compressed or releases energy, the transition sleeve 53 is driven to linearly slide back and forth on the first mounting groove 521, and the face cover 1 is driven to linearly slide to return to the initial position.

For the transition sleeve 53, preferably, as shown in fig. 11, the transition sleeve 53 includes a mounting portion 531 and an abutting portion 532 fixed on one end of the mounting portion 531, and a first step is formed between the abutting portion 532 and the mounting portion 531; the mounting portion 531 is fitted into the first mounting groove 521 and is stopped by the notch of the first mounting groove 521 in the first mounting groove 521, and the abutting portion 532 passes through the notch of the first mounting groove 521 to protrude out of the first mounting groove 521.

That is, the mounting portion 531 has a dimension that is greater than the notch dimension of the first mounting slot 521, and the abutment portion 532 has a dimension that is less than the notch dimension of the first mounting slot 521, so as to limit the mounting portion 531 to slide within the first mounting slot 521, thereby enabling the sliding connection between the transition sleeve 53 and the first mounting slot 521.

To facilitate the installation of the mounting portion 531 of the transition piece 53 into the first mounting groove 521, as shown in fig. 11, the top of the first mounting groove 521 is formed with an opening 5211, and the mounting portion 531 is inserted into the first mounting groove 521 through the opening 5211.

Preferably, the mounting seat 52 has a rectangular parallelepiped shape, the corresponding mounting portion 531 has a rectangular parallelepiped shape, and the abutting portion 532 has a cylindrical shape. Of course, the mounting seat 52 and the mounting portion 531 may be cylindrical or have other shapes, so long as they form a sliding fit. For example, the transition sleeve 53 may also be slidably sleeved outside the groove wall of the first mounting groove 521. The abutting portion 532 may have a cylindrical shape or other shape, and the specific structure is not limited, and only one end of the first biasing member 51 is inserted into the inner cavity of the abutting portion 532.

As for the first blocking member 11, as shown in fig. 5, 6 and 10, the first blocking member 11 may be a stopper protruding downward and provided on the inner wall of the face cover 1, or a protrusion. The block or the bulge is in an inverted L shape, and the abutting part abuts against the vertical part of the inverted L shape. Or other shapes can be adopted, for example, the shape is T-shaped, the abutting part abuts against the vertical part of the T-shaped, and the specific shape of the first blocking part can be selected according to actual requirements and is not particularly limited.

As shown in fig. 5 and 12, preferably, the holding mechanism further includes a second blocking member 12 provided on the face cover 1, and the mount 52 is located between the first blocking member 11 and the second blocking member 12; under the second biasing force, the second blocking member 12 may abut on the outer side wall of the mount 52.

When the pushing force to the face cover is removed from the outside, the face cover 1 is slid and reset toward the left side in fig. 12 under the first biasing force (toward the left side in fig. 12) of the first biasing member 51, and during this resetting, when the second stopper 12 of the face cover 1 abuts on the outer side wall of the mount seat 52, the face cover 1 is reset to the initial position, and the second stopper 12 prevents the face cover 1 from continuing to slide toward the left side, preventing the face cover 1 from slipping off the inner lid 2.

As shown in fig. 13a and 11, the first blocking member 11, the second blocking member 12 and the face cover 1 define a second mounting groove 13 therebetween, the second mounting groove 13 is sleeved on the mounting seat 52, and the groove bottom of the second mounting groove 13 abuts on the opening 5211 at the top of the mounting seat 52, so as to limit the mounting portion 531, thereby enabling the mounting seat 52, the first blocking member 11, the second blocking member 12, the transition sleeve 53 and the first biasing member 51 to be assembled compactly and occupy a small space.

Further, as shown in fig. 12, the holding mechanism further includes a third stopper 54 provided on the inner lid 2; in the slide opening of the face cover 1, the third stopper 54 may apply a stopper force to the face cover 1 in the same direction as the first biasing force to restrict the slide of the face cover 1.

The second blocking member 12 prevents the surface cover 1 from sliding down the inner cap 2 under the first biasing force, and the third blocking member 54 prevents the surface cover 1 from excessively pressing the first biasing member 51 during the cover opening process, so that when the surface cover 1 slides to the third blocking member 54, the third blocking member 54 exerts a blocking force on the surface cover 1, and the surface cover 1 is blocked from moving further away from the cover closing buckle 32 to protect the first biasing member 51.

Preferably, as shown in fig. 3, 4, 5 and 12, the movable buckle 31 is rotatably disposed in the interior of the face cover 1, and the face cover 1 is provided with a first relief hole 141 for the first locking end 311 of the movable buckle 31 to protrude out, so as to form the mating end 14 of the face cover 1; in the slide-opening of the face cover 1, the third blocking member 54 may exert a blocking force against the mating end 14 to protect the first biasing member 51.

As shown in fig. 4, the reset component 4 is a torsion spring, and the torsion spring is sleeved on the rotating shaft of the movable catch 31 to apply a second biasing force to the movable catch 31.

As shown in fig. 12, the third stopper 54 is a second step provided on the outer peripheral end surface of the inner lid 2; the second step has a step surface 541 and a blocking surface 542 perpendicular to the step surface 541; the mating end 14 abuts against the step surface 541 and can slide on the step surface 541 with the surface cover 1, and the blocking surface 542 can apply a blocking force to the mating end 14.

The bottom of the mating end 14 of the face cover 1 is always abutted against the step surface 541, when the cover needs to be opened, as shown in fig. 13b, the face cover 1 slides towards the right side under the external driving force in fig. 13b, the first biasing member 51 is compressed, the mating end 14 of the face cover 1 slides on the step surface 541 along with the face cover 1 until the mating end 14 slides to the state shown in fig. 14a and the end surface of the mating end 14 abuts against the blocking surface 542, and the face cover 1 slides in place; in the process, the face cover 1 drives the movable lock catch to be separated from the cover closing buckle, and the first biasing part 51 cannot be extruded in a transitional mode in the cover opening process.

As a variant, the third stop 54 may also have another configuration, since the inner cap 2 does not slide, for example, in fig. 14b, the third stop 54 does not act on the mating end 14 of the face cap 1, but on the second stop 12. The third stoppers 54 are disposed on the inner cap 2 so as to be opposed to the mounting seat 52, the second stoppers 12 are disposed between the mounting seat 52 and the third stoppers 54, and the third stoppers 54 limit the sliding movement of the face cap 1 toward the right side.
