The top of the outer pot 120 can be connected with the middle plate 110, and the bottom of the outer pot 120 is connected with the base. In this embodiment, the outer pot 120 may be connected to the middle plate 110 by a rotary clamping manner. Specifically, as shown in fig. 1 to 3, the outer pan 120 may include a flange 121 extending outward from a pan opening peripheral side thereof and a protrusion 122 integrally configured with the flange 121. The flange 121 extends radially outward. The flange 121 may be, for example, a straight wall. The projections 122 are provided in plurality at intervals in the circumferential direction. The middle plate 110 may have a snap 114 vertically spaced from the top wall. The plurality of engaging portions 114 are provided at intervals, and correspond to the positions of the projections 122.

It should be noted that fig. 2 only schematically indicates the positions of L1 and L2. The size of the reinforcing recess 125 in the circumferential direction is L2 and may be 1/4L1 ≦ L2 ≦ 1/2L 1. For example, dimension L2 may be 1/4, 2/5, 3/7, 4/9, 1/2, and the like. As shown in fig. 5, a dimension L31 of the projection in the radial direction may be 2mm to 5mm, for example, a dimension L31 may be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, or the like. The dimension L32 of the reinforcing recess 125 recessed inward in the radial direction may be 1mm to 5mm, for example, the dimension L32 may be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, or the like.

The size of the reinforcing concave part 125 in the circumferential direction and the size of the reinforcing concave part recessed inwards in the radial direction can enable the protruding part 122 of the outer pot 120 to bear certain external force, the protruding part is not easy to deform, the size and/or area of the clamping connection between the protruding part 122 and the middle plate 110 are suitable, the protruding part 122 is stably and reliably clamped with the middle plate 110, and the clamping connection stability is good.

The dimension L4 of the snap wall 124 in the axial direction may be 4mm to 6mm, for example, the dimension L4 may be 4mm, 4.6mm, 4.8mm, 4.9mm, 5.0mm, 5.1mm, 5.2mm, 5.5mm, 6mm, and the like. Compared with the existing clamping structure, the axial size of the clamping wall 124 is increased in the embodiment, the capacity of the convex part 122 of the outer pot 120 for resisting external force can be increased, the connection stability between the outer pot 120 and the middle plate 110 is further improved, and the possibility of loosening the outer pot 120 is reduced.

The walls forming the reinforcing recess 125 may extend in the axial direction. In other words, the wall of the reinforcing recess 125 is a straight wall extending in the axial direction. The structural strength of the protrusion 122 can be increased to a greater extent, and the overall external structure of the outer pot 120 is simple, neat and beautiful, and is convenient to produce and manufacture.

The flange 121 may be provided with a reinforcing wall 126 extending downwardly from the periphery thereof. Reinforcing wall 126 is connected to catch wall 124. And the lower surface of the reinforcing wall 126 is flush with the lower surface of the catching wall 124. Therefore, the structural strength of the turned-over edge 121 and the structural strength of the protruding part 122 can be increased, the structural strength of the pot opening of the outer pot 120 is further prevented from being good, and deformation is not easily caused by stress.
