[Specific implementation method]

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0022] Example 1: Please refer to the attached Figure 1 To Attachment Figure 4 The present embodiment provides an outer pot fixing ring for an electric rice cooker, comprising a fixing ring body 1, a fitting mechanism 2 and a limiting mechanism 3 arranged on the fixing ring body 1, wherein the inner side of the fixing ring body 1 is surrounded by a ring opening 11 which can be sleeved on the outer side of an inner pot of the electric rice cooker, the fitting mechanism 2 is used to abut against the opening edge of the inner pot of the electric rice cooker to limit the downward movement of the inner pot of the electric rice cooker along the height direction of the fixing ring body 1, and the limiting mechanism 3 includes a limiting groove 31 of a corresponding structure for clamping the inner pot of the electric rice cooker to limit the rotation of the inner pot of the electric rice cooker around the axial direction of the fixing ring body 1. The outer pot fixing ring for the electric rice cooker of the present embodiment adopts the cooperation of the interlocking mechanism 2 and the limiting mechanism 3 on the fixing ring body 1, so that the inner pot of the electric rice cooker can pass through the ring opening 11 and be placed in the fixing ring body 1. At this time, the fixing ring body 1 is sleeved on the outer side of the inner pot of the electric rice cooker to support the inner pot of the electric rice cooker, and the corresponding structure of the inner pot of the electric rice cooker is clamped in the limiting groove 31 of the limiting mechanism 3, so that the fixing ring body 1 can limit the rotation of the inner pot of the electric rice cooker, avoid unnecessary wear caused by the inner pot of the electric rice cooker being mounted on the outer pot fixing ring, and improve the heating efficiency of the inner pot of the electric rice cooker.

[0023] The fixing ring body 1 is provided with an engaging wall 12 around the circumference of the ring opening 11, and the limiting mechanism 3 includes at least one limiting groove 31, the limiting groove 31 is provided on the engaging wall 12, and the limiting abutting surfaces 32 are provided on both opposite sides of the limiting groove 31. When the corresponding structure of the inner pot of the electric rice cooker is clamped in the limiting groove 31, the limiting abutting surface 32 abuts the corresponding structure of the inner pot of the electric rice cooker around the axial direction of the fixing ring body 1 to limit the clockwise or counterclockwise rotation of the inner pot of the electric rice cooker around the axial direction of the fixing ring body 1. Preferably, the limiting mechanism 3 includes two limiting grooves 31 relatively arranged on the engaging wall 12. Among them, the corresponding structure that cooperates with the rice cooker inner pot and the limiting groove 31 is generally the handle lug of the rice cooker inner pot. After the handle lug of the rice cooker inner pot is clamped in the limiting groove 31, the limiting abutment surface 32 can abut the end of the handle lug to limit the movement of the handle lug in the limiting groove 31, thereby limiting the axial rotation of the rice cooker inner pot around the fixed ring body 1.

[0024] An arc-shaped transition groove 33 extending around the axial direction of the fixing ring body 1 is provided in the limiting groove 31, and both ends of the arc-shaped transition groove 33 are respectively connected to the opposite limiting abutment surfaces 32. The provision of the arc-shaped transition groove 33 can not only prevent stress concentration and increase the strength of the fixing ring body 1, but also prevent dirt from accumulating and facilitate the cleaning of the fixing ring body 1.

[0025] The limiting groove 31 is provided with a limiting receiving surface 34 and a limiting surrounding surface 35 on both sides of the arc-shaped transition groove 33, respectively. The limiting receiving surface 34 is horizontally arranged upward, and its two ends are respectively connected to the relative limiting abutting surface 32, and the limiting surrounding surface 35 is arranged in an arc shape facing the ring opening 11, and its two ends are respectively connected to the relative limiting abutting surface 32. The limiting receiving surface 34 can play the role of receiving the handle lug of the inner pot of the rice cooker, and the limiting surrounding surface 35 can surround the handle lug of the inner pot of the rice cooker in the height direction, which can prevent the handle lug from escaping from the limiting groove 31 due to misoperation such as bumping, thereby ensuring the stable placement of the inner pot of the rice cooker.

[0026] The fitting mechanism 2 includes a plurality of protrusions 21 and a retaining recess 22 provided on the fixing ring body 1, wherein the protrusions 21 are arranged in a circumferential array around the surface of the fitting wall 12, and the retaining recess 22 are arranged in a circumferential array around the top of the fitting wall 12. Preferably, an upper inclined surface 211 and a lower inclined surface 212 are provided on the protrusion 21, and the protruding height of the lower inclined surface 212 toward the ring opening 11 is higher than the protruding height of the upper inclined surface 211 toward the ring opening 11; and oppositely arranged pre-calibrated inclined surfaces 221 are provided at both ends of the retaining recess 22. When the inner pot of the rice cooker passes through the ring opening 11 and is placed into the fixed ring body 1, the upper inclined surface 211 of the protrusion 21 plays a certain abutting and guiding role on the inner pot of the rice cooker. When the inner pot of the rice cooker passes through the ring opening 11 and is placed into the fixed ring body 1 to a certain depth, the lower inclined surface 212 of the protrusion 21 will surround and press the inner pot of the rice cooker. At this time, the inner pot of the rice cooker completes the cooperation with the interlocking mechanism 2. The upper edge of the inner pot of the rice cooker can be provided with a flange structure that can abut against the retaining recessed edge 22 to further limit the rotation of the inner pot of the rice cooker around the axis. The setting of the pre-calibration inclined surface 221 also has a pre-positioning and guiding role on the flange structure of the inner pot of the rice cooker.

[0027] The fixing ring body 1 is provided with a plurality of installation positioning openings 13 on the side facing away from the embedding wall 12. Then, the fixing ring body 1 is also provided with a plurality of screw fixing columns 14 on the side facing away from the embedding wall 12. Each screw fixing column 14 arranges adjacent installation positioning openings 13 at intervals. The arrangement of the installation positioning openings 13 facilitates the installation and positioning of the fixing ring body 1 during the assembly of the rice cooker. The arrangement of the screw fixing columns 14 facilitates the screw fixing of the fixing ring body 1 after positioning.
