When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0040] On the one hand, if Figure 1 and Figure 2 、 Figure 3 As shown, an anti-leakage structure in one embodiment of the present invention includes a cover body 1, a bubble breaker 2, an anti-leakage assembly 3 and an inner cover 4; the cover body 1 is provided with a recessed groove 101 for accommodating the bubble breaker 2, and an inner cover groove 102, the inner cover 4 is installed on the inner cover groove 102 and covers the bubble breaker 2; the anti-leakage assembly 3 includes a limiting unit 31, the limiting unit 31 includes a limiting member 32 and an elastic member 33, the limiting member 32 is provided with a first protrusion 321 and a second protrusion 322; the elastic member 33 presses the limiting member 32, the first protrusion 321 protrudes into the recessed groove 101, and the second protrusion 322 protrudes into the inner cover groove 102.

[0041] The above-mentioned anti-leakage structure is provided with an anti-leakage assembly 3. When the bubble breaker 2 is placed in the recessed groove 101, the bubble breaker 2 squeezes the first protrusion 321, and the second protrusion 322 moves in a direction away from the inner cover groove 102 as the first protrusion 321 moves and retracts into the inside of the cover body 1, and the inner cover 4 can be installed in the inner cover groove 102; when the recessed groove 101 is not filled with the bubble breaker 2, the elastic member 33 presses the limit member 32, and the second protrusion 322 protrudes into the inner cover groove 102, and the inner cover 4 cannot be installed in the inner cover groove 102.

[0042] In one embodiment, a connecting assembly 5 for mounting the inner cover 4 on the cover body 1 is further included. The inner cover 4 includes a circular cover plate 41, which is provided with a first flange 42 and a second flange 43 along the same diameter. The connecting assembly 5 includes a position-limiting mounting groove 51 and a spring-pressing unit 52 provided on the cover body 1. The position-limiting mounting groove 51 is adapted to fit the first flange 42. Thus, the spring-pressing unit 52 springs the second flange 43 and presses the first flange 42 into the position-limiting mounting groove 51, thereby completing the installation of the inner cover 4 into the inner cover groove 102.

[0043] like Figure 3 and Figure 4 、 Figure 5 、 Figure 6 As shown, in one embodiment, the spring unit 52 includes a second spring 53 and a spring member 54. The second spring 53 springs the spring member 54 toward the position-limiting mounting groove 51. The anti-leakage structure further includes a spring member 7 disposed on the pot body, the spring member 7 having a spring flange 71. The spring member 54 has a spring-limiting groove adapted to the second flange 43 and a spring-limiting groove adapted to the spring flange 71. Thus, when the inner cover 4 is not installed in the inner cover groove 102, the second spring 53 springs the spring member 54 toward the position-limiting mounting groove 51, preventing the spring flange 71 from snapping into the spring-limiting groove, and the lid 1 cannot be closed onto the pot body. When the inner cover 4 is installed in the inner cover groove 102, the second flange 43 snaps into the spring-limiting groove and compresses the second spring 53, allowing the spring flange 71 to snap into the spring-limiting groove, and the lid 1 can be closed onto the pot body.

[0044] In a specific embodiment, when the second flange 43 is buckled into the spring-loaded limit groove, the compression size of the second spring 53 is adapted to the groove depth of the spring-loaded limit groove; when the second flange 43 is not buckled into the spring-loaded limit groove, the second spring 53 presses the spring-loaded limit groove of the spring-loaded part 54 to move toward the direction of the limit mounting groove 51, and the spring-loaded flange 71 cannot be buckled into the spring-loaded limit groove.

[0045] In one embodiment, the spring member 54 has a pressing end and a spring end. One end of the second spring 53 presses against the cover 1, while the other end presses against the pressing end. Specifically, the spring-pressing retaining groove is a V-shaped positioning notch provided at the spring end, and the second flange 43 is provided with an A-shaped positioning protrusion. This creates a large contact surface between the spring-pressing retaining groove and the second flange 43, improving the spring-pressing effect.

[0046] In one embodiment, the stopper 32 is J-shaped and includes a long horizontal piece 34, a short horizontal piece 35, and a vertical connecting piece 36 connecting the long horizontal piece 34 and the short horizontal piece 35. The width of the inner cover groove 102 is greater than the width of the recessed groove 101. The first protrusion 321 is provided on the long horizontal piece 34, and the second protrusion 322 is provided on the short horizontal piece 35. Thus, by designing the stopper 32 in a J-shape, when the bubble breaker 2 squeezes the first protrusion 321, the second protrusion 322 moves with the first protrusion 321, moving away from the inner cover groove 102 and retracting into the interior of the cover body 1.

[0047] In one embodiment, the anti-leakage assembly 3 further includes a guide unit 37; the guide unit 37 comprises a guide post 371 fixedly mounted on the cover 1 and a guide slot 372 disposed on the long cross piece 34, with the guide slot 372 adapted to fit within the guide post 371. Thus, the guide post 371 and the guide slot 372 cooperate to define the sliding direction and size of the stopper 32, resulting in a compact and reliable structure.

[0048] In one embodiment, the bubble breaker 2 is provided with a limiting groove adapted to the end of the first protrusion 321. Thus, by adapting the limiting groove to the first protrusion 321, the top position and top depth of the first protrusion 321 are accurately defined. When the bubble breaker 2 presses the first protrusion 321, the second protrusion 322 moves with the first protrusion 321, moving away from the inner cover groove 102 and smoothly retracting into the interior of the cover body 1.

[0049] In one embodiment, the elastic member 33 is a first spring, and the retaining member 32 is provided with a mounting slot 301 for receiving the first spring. One end of the first spring is seated in the mounting slot 301, while the other end is pressed against the cover wall of the lid 1. Specifically, the mounting slot 301 is provided with a mounting boss that engages the centerline of the first spring coil. Thus, when the recessed groove 101 is not fitted with the bubble breaker 2, the first spring presses against the retaining member 32, causing the first protrusion 321 to protrude into the recessed groove 101 and the second protrusion 322 to protrude into the inner cover groove 102.

[0050] like Figure 1 and Figure 3 、 Figure 4As shown, in one embodiment, the cover body 1 is provided with an exhaust channel 103 connected to the recessed groove 101. The exhaust channel 103 is provided with a sealing ring 11 on the side facing the recessed groove 101. The sealing ring 11 is provided with a recessed groove 111 on the side facing the recessed groove 101. The top of the bubble breaker 2 is provided with an exhaust port 22, and the exhaust port 22 is provided with an outward gas guide flange 221 that adapts to the recessed groove 111. In this way, the exhaust port 22 on the top of the bubble breaker 2 is tightly connected to the exhaust channel 103 through the sealing ring 11, thereby preventing gas and liquid from seeping into the interior of the cover body 1.

[0051] In one embodiment, the circular cover plate 41 is further provided with a convex arc edge 44 protruding from the plate surface. Specifically, the cover body 1 is provided with a notched flange adapted to the convex arc edge 44. This allows the user to easily grasp the circular cover plate 41, i.e., the inner cover 4, through the convex arc edge 44, thereby facilitating installation or removal of the inner cover 4.

[0052] On the one hand, if Figure 5 As shown, an electric rice cooker in one embodiment of the present invention comprises a rice cooker body 6 and a leakage-proof structure, wherein the cover body 1 is hinged to the rice cooker body 6 .

[0053] In one embodiment, the pot body 6 includes a shell 61 with a heating chamber 601, a heating assembly 62 disposed at the bottom of the heating chamber 601, and an inner pot 63 disposed within the heating chamber 601. Thus, the inner lid 4 is installed on the inner lid groove 102, covering the bubble breaker 2, and the leak-proof cover is attached to the pot body 6. The heating assembly 62 is activated to heat the inner pot 63 within the heating chamber 601, thereby performing the cooking operation.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
