For example: when the liner support 500 needs to be further fixed by screws, in the process of screwing, the relative position of the liner support 500 in the assembly hole 410 is adjusted by the deformation of the flexible positioning structure, so that the deviation of screw hole positions between the liner support 500 and the part to be fixed is reduced or eliminated, and the problem that the screwing is difficult due to the overlarge deviation of the screw hole positions between the liner support 500 and the part to be fixed is solved. The following description is made with reference to specific examples:

Referring to fig. 7 and 8, in an embodiment of the present invention, the electric pressure cooker according to the above embodiment: the electric pressure cooker of this embodiment further includes a base 110 and a heat-insulating cover holder 600, the heat-insulating cover holder 600 includes a first connecting portion 610, a second connecting portion 620 and a supporting portion 630 connecting the two, the first connecting portion 610 is fixedly connected to the base 110, and the second connecting portion 620 is connected to the inner container support 500 at intervals of the wire coil fixing base 320. Preferably: the first connecting portion 610 is connected with the base 110 through screws, the second connecting portion 620 is connected with the liner supporting member 500 through screws, and the fixing mode of the screw connection is simple, easy to operate and low in cost.

In this embodiment, the heat-insulating cover holder 600 belongs to a separately arranged component, and can be adaptively changed according to the need of the assembly structure of the wire coil assembly, the base 110 and the heat-insulating cover 300, for example, by changing the structure of the first connecting portion 610 of the heat-insulating cover holder 600, the problem of connection adaptation between the heat-insulating cover holder 600 and bases 110 of different models is solved, that is, the problem of adaptation of the wire coil assembly, the heat-insulating cover 300 and the base 110 in different models is solved, and the universality of the base 110 is improved; even on the same model, the assembly tolerance of the wire coil assembly, the heat preservation cover 300 and the base 110 can be eliminated by adjusting the heat preservation cover bracket, and the convenience and the assembly quality of product assembly are improved.

The heat preservation cover bracket 600 which is arranged independently can be made of materials with higher strength without being limited by the materials of the wire coil assembly or the base 110, so that the bearing strength of the supporting structure is improved, the wire coil assembly and the heat preservation cover 300 are stably supported, and the structural stability of the product is enhanced. Preferably, the heat-insulating cover holder 600 of the present embodiment is formed by bending two sides of a metal sheet in opposite directions, for example, one side of the metal sheet is bent by 90 ° to form a first connecting portion 610, the other side of the metal sheet is bent by 90 ° in the opposite direction to form a second connecting portion 620, a portion between the first connecting portion 610 and the second connecting portion 620 is a supporting portion 630, and the first connecting portion 610, the second connecting portion 620 and the supporting portion 630 substantially form a Z-shaped structure. The heat preservation cover support 600 that the sheetmetal bending type formed, structural strength is high to can stably support heat preservation cover 300 and drum subassembly, can also improve the screw joint strength of second connecting portion 620 and drum subassembly and first connecting portion 610 and base 110.

In conjunction with fig. 2, it is preferred that: the wire coil fixing seat 320 of this embodiment is provided with a sinking platform 330 that is recessed towards the direction away from the base 110, and the second connecting portion 620 is fixed in the sinking platform 330, for example: the through holes 331 are formed in the sinking platform 330 corresponding to the screw connection holes 510 of the liner support 500, screws sequentially penetrate through the second connection part 620 and the sinking platform 330 and then are locked in the screw connection holes 510 of the liner support 500, and the sinking platform 330 is clamped between the inside and the outside of the second connection part 620 and the liner support 500 to realize fixation. The second connecting part 620 is fixed in the sinking platform 330, so that the distance between the heat-insulating cover 300 and the base 110 can be shortened, and the height of the heat-insulating cover 300 and the base 110 after being assembled is reduced; the platform 330 may also increase the structural strength of the wire spool holder 320, making it more stable with respect to the wire spool assembly.

Based on the above preferred scheme, the screw connection holes 510 on the liner support 500 deviate from the center of the liner support 500 in the direction away from the center of the wire coil assembly, and the position of the corresponding through hole 331 on the sinking platform 330 also needs to be adjusted accordingly, so that the radial width of the sinking platform 330 can be reduced, the radial size of the wire coil assembly can be enlarged, a better electromagnetic induction heating effect can be obtained, and enough space can be left between the through hole 331 and the radial inner side of the sinking platform 330 to match the fixation of the second connection portion 620.

In the embodiment, the insertion position of the liner support 500 in the assembly hole 410 is determined to ensure that the screw connection hole 510 of the liner support 500 after installation deviates in a direction away from the center of the wire coil assembly, and for this reason, the liner support 500 is limited to rotate circumferentially in the sleeve, which not only prevents the liner support 500 from being installed in a wrong direction, but also facilitates subsequent screw connection with the second connection portion 620. The following are exemplary: referring to fig. 4 and 5, the upper end of the liner support 500 is provided with a protruding brim 520 extending radially outward, the protruding brim 520 is provided with a fool-proof groove 521 having a downward opening, the hole wall of the assembly hole 410 is provided with a fool-proof protrusion 450, only when the liner support 500 is inserted into the assembly hole 410 at a predetermined insertion position, the fool-proof protrusion 450 can be inserted into the fool-proof groove 521, the screw connection hole 510 deviates in a direction away from the center of the wire coil assembly, and the liner support 500 cannot rotate in the assembly hole 410 due to the limitation of the fool-proof protrusion 450, so as to ensure that the screw connection hole 510 is aligned with the through hole 331 on the sink 330. If the liner support 500 is not inserted into the assembly hole 410 at the predetermined insertion position, the fool-proof protrusion 450 interferes with the protruding brim 520 in the axial direction of the liner support 500, so that the liner support 500 cannot be inserted in place, and the cooperation of the fool-proof protrusion 450 and the fool-proof groove 521 can prevent the liner support 500 from being incorrectly inserted in place and can limit the rotation of the liner support 500 in the assembly hole 410. Of course, in other embodiments, the fool-proof protrusion and the fool-proof groove may be interchanged, the fool-proof protrusion is disposed on the protruding brim of the liner supporting member, and the fool-proof groove is disposed on the hole wall of the assembling hole, which may also achieve the technical effect of this embodiment.
