Since the insulating inner cover is an important sealing component of the pot lid, when the user removes the insulating inner cover for cleaning, if the insulating inner cover is not correctly installed on the inner side of the lid body, it will cause the electric rice cooker to leak during cooking, the rice will not be cooked, and the cooked rice will taste bad, etc., affecting the user's experience. Therefore, designing a pot lid that can prevent users from installing the insulating inner cover incorrectly is a technical problem that electric rice cooker designers urgently need to solve, which has important practical significance for improving the user experience of electric rice cookers. Utility Model Content

[0003] The utility model provides an electric rice cooker and a pot cover with a fool-proof assembly structure, aiming at least to solve the technical problem that the existing pot cover is easy to be wrongly assembled after the heat-insulating inner cover is removed and cleaned, resulting in loose sealing.

[0004] The utility model proposes a pot cover with an anti-foolproof assembly structure, the pot cover comprises a cover body and an insulation inner cover; the inner side surface of the cover body has an accommodating cavity, and the anti-foolproof assembly structure comprises: a positioning groove and a locking groove arranged on the side wall of the accommodating cavity, the positioning groove and the locking groove are arranged opposite to each other, and an anti-foolproof column is arranged in the locking groove; a first protrusion and a second protrusion are arranged on the side edge of the insulation inner cover, and an anti-foolproof hole is arranged at a position where the second protrusion deviates from the center; wherein the insulation inner cover is assembled in the accommodating cavity, the first protrusion is limited in the positioning groove, the anti-foolproof column is inserted in the anti-foolproof hole and makes the second protrusion limited and fixed in the locking groove.

[0005] In some preferred embodiments, the notch of the positioning groove and the notch of the locking groove are arranged opposite to each other, and the notch width of the positioning groove is different from the notch width of the locking groove.

[0006] In some preferred embodiments, the positioning groove is provided with a limiting hole or a limiting block, and the first protrusion is inserted into the limiting hole, or the first protrusion is inserted between the limiting block and the bottom of the accommodating cavity.

[0007] In some preferred embodiments, the number of the first protrusions is two, and the two first protrusions are arranged at intervals; the number of the limiting holes or the limiting blocks is two, and the two limiting holes are arranged at intervals.

[0008] In some preferred embodiments, the interval between the two first protrusions is greater than the slot width of the locking slot.

[0009] In some preferred embodiments, a locking piece is provided in the locking groove, and the locking piece cooperates with the second protrusion to fix the heat-insulating inner cover in the accommodating cavity.

[0010] In some preferred embodiments, a buckle is provided at the end of the locking member, and the buckle is buckled and fixed with the second protrusion.

[0011] In some preferred embodiments, the buckle has a first guiding bevel, and the second protrusion has a second guiding bevel, and when the second guiding bevel abuts against the first guiding bevel, a bevel fit is formed to guide the end of the second protrusion to be engaged with the buckle.

[0024] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0025] like Figure 1 As shown, the utility model discloses a pot cover with a fool-proof assembly structure, the pot cover comprises a cover body 1 and an insulating inner cover 2, a receiving cavity 11 is provided on the inner side of the cover body 1, the insulating inner cover 2 can be detachably assembled in the receiving cavity 11, so that the user can remove the insulating inner cover 2 for cleaning.

[0026] There is a foolproof assembly structure between the cover body 1 and the heat-insulating inner cover 2, and the foolproof assembly structure plays at least two roles:

[0027] 1. The heat-insulating inner cover 2 is provided to be detachably assembled in the accommodating cavity 11 on the inner side of the cover body 1 according to a fool-proof assembly structure.

[0028] 2. When the heat-insulating inner cover 2 is removed for cleaning and then installed back into the accommodating cavity 11, a fool-proof function is provided to prevent the heat-insulating inner cover 2 from being installed incorrectly and causing the overall seal of the pot cover to be loose, thereby ensuring that the heat-insulating inner cover 2 can be correctly assembled in the accommodating cavity 11 so that the pot cover has a reliable overall sealing performance.

[0029] Specifically, the fool-proof assembly structure includes: a positioning groove 12 and a locking groove 13 arranged on the side wall of the accommodating cavity 11, the positioning groove 12 is arranged opposite to the locking groove 13, and an fool-proof column 16 is arranged in the locking groove 13; a first protrusion 21 and a second protrusion 22 are arranged on the side edge of the thermal insulation inner cover 2, and an fool-proof hole 23 is provided at a position off-center from the second protrusion 22.

[0030] Further integration Figure 2-Figure 4As shown, when the thermal insulation inner cover 2 is correctly assembled with the cover body 1 using the fool-proof assembly structure, the thermal insulation inner cover 2 is assembled in the accommodating cavity 11, the first protrusion 21 is limited in the positioning groove 12, the fool-proof column 16 is inserted in the fool-proof hole 23 and the second protrusion 22 is limited and fixed in the locking groove 13.

[0031] Since the fool-proof hole 23 is set at a position offset from the center of the second protrusion 22, the position of the fool-proof column 16 will match the fool-proof hole 23 only when the thermal insulation inner cover 2 is inserted into the accommodating cavity 11 in the correct orientation, thereby ensuring that the fool-proof column 16 is inserted in the fool-proof hole 23; and only after the fool-proof column 16 is inserted in the fool-proof hole 23 can the conditions be created for the second protrusion 22 to be limited and fixed in the locking groove 13, thereby utilizing the anti-fool-proof column 16 and the fool-proof hole 23 to provide an anti-fool function during the detachable assembly process of the thermal insulation inner cover 2 and the cover body 1.

[0032] Considering that the pot cover has a set of pivot seats 19, which are rotatably connected to the main body of the rice cooker, when the user disassembles and assembles the heat-insulating inner cover 2, the cover body is usually in an open state of nearly 90 degrees relative to the main body of the rice cooker, and the positioning groove 12 is usually set at the lower position or the bottom position of the side wall of the accommodating cavity 11, and the locking groove 13 is set at the upper position or the top position of the side wall of the accommodating cavity 11. That is, the cover body 1 has a set of pivot seats 19, and the pivot seats 19, the positioning groove 12 and the locking groove 13 are arranged on the same midline, and the positioning groove 12 is arranged close to the pivot seats 19.

[0033] When assembling the thermal insulation inner cover 2 with the cover body 1, first insert the first protrusion 21 of the thermal insulation inner cover 2 into the positioning groove 12 of the cover body 1. Since the positioning groove 12 is located above the pivot seat 19 and at the bottom end of the side wall of the accommodating cavity 11, the weight of the thermal insulation inner cover 2 falls on the positioning groove 12. When the user then performs the operation of limiting and fixing the second protrusion 22 in the locking groove 13, the force required is relatively small, thereby facilitating the user's assembly operation.

[0034] The notch of the positioning groove 12 is arranged opposite to the notch of the locking groove 13, and the notch width of the positioning groove 12 is different from the notch width of the locking groove 13. Setting the two notches with different widths can also play a foolproof role. When the user is assembling, if the second protrusion 22 cannot be inserted into the positioning groove 12, it can serve as a reminder to the user.

[0035] The positioning groove 12 is provided with a limiting hole or a limiting block 14 , and the first protrusion 21 is inserted into the limiting hole, or the first protrusion 21 is inserted between the limiting block 14 and the bottom of the accommodating cavity 11 .

[0036] Generally speaking, there are two first protrusions 21, and the two first protrusions 21 are arranged at intervals; the limiting holes or the limiting blocks 14 are both arranged at intervals. Moreover, the interval between the two first protrusions 21 is greater than the slot width of the locking groove 13. Such an arrangement not only has a better limiting function of using the two limiting blocks 14 to limit the two first protrusions 21 at intervals, but also has a foolproof effect, so that the two limiting blocks 14 can only be inserted into the positioning groove 12 but cannot be inserted into the locking groove 13.

[0037] A locking member 15 is provided in the locking groove 13 , and the locking member 15 cooperates with the second protrusion 22 to fix the heat-insulating inner cover 2 in the accommodating cavity 11 .

[0038] Specifically, the end of the locking member 15 has a buckle, and the buckle is buckled with the second protrusion 22. The buckle has a first guiding inclined surface 151, and the second protrusion 22 has a second guiding inclined surface 221. When the second guiding inclined surface 221 abuts against the first guiding inclined surface 151, an inclined surface is formed to guide the end of the second protrusion 22 to be buckled with the buckle.

[0039] When the thermal insulation inner cover needs to be removed, it is only necessary to apply an external force to the buckle in a direction away from the second protrusion 22 to disengage the buckle from the end of the second protrusion 22, thereby releasing the limiting cooperation relationship between the locking member 15 and the second protrusion 22 and allowing the second protrusion 22 to disengage from the locking groove 13; then lift the thermal insulation inner cover 2 to disengage the first protrusion 21 from the positioning groove 12, and the operation of removing the thermal insulation inner cover 2 is completed.

[0040] In order to understand the foolproof principle of the foolproof assembly structure, see Figure 5-Figure 7As shown, when the heat-insulating inner cover 2 is mistakenly inserted into the accommodating cavity 11 in reverse, although the first protrusion 21 located at the bottom position can be correctly inserted into the positioning groove 12; however, since the anti-fool hole 23 is set at a position offset from the center of the second protrusion 22, when the heat-insulating inner cover 2 is reversely inserted into the accommodating cavity 11, the position of the anti-fool hole 23 does not correspond to the anti-fool hole 23, and the end of the anti-fool column 16 abuts against the second protrusion 22 and cannot be accurately inserted into the anti-fool hole 23, so that the second protrusion 22 cannot be further pressed into the positioning groove 12, and then the second protrusion 22 cannot form a lock with the buckle of the locking piece 15, so that the second protrusion 22 cannot be limited and fixed in the locking groove 13. At this time, if the user's hands leave the heat-insulating inner cover 2, the heat-insulating inner cover 2 will overturn relative to the cover body 1 under the action of its own gravity, which can intuitively remind the user that it is not assembled correctly, thereby avoiding the user from using the pot cover with the heat-insulating inner cover 2 not assembled correctly for cooking.

[0041] The utility model also discloses an electric rice cooker, which is provided with the pot cover.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
