[0001] This utility model relates to the field of household appliance technology, specifically to a cover assembly and a device having a cover assembly. Background Technology

[0002] The lid assembly, such as that of an electric kettle, typically consists of a plastic lid and a stainless steel lid. The stainless steel lid comes into direct contact with water vapor, ensuring the kettle meets hygiene requirements. There are various methods for installing the plastic and stainless steel lids. One method involves securing the plastic and stainless steel lids with multiple stainless steel screws, with the screw heads usually located on one side of the stainless steel lid. When the kettle lid is opened, the screw heads are directly visible. This structure has a lower aesthetic appeal, and if the screws and stainless steel lid are not properly sealed, air leakage may occur. Another method involves welding a nut bracket to the stainless steel lid, and then securing a plastic bracket to the nut bracket with screws. Utilizing the elasticity of the plastic lid, the lid is then snapped onto the bracket. This method improves the aesthetic appeal, but it involves more parts, a more complex manufacturing and assembly process, and higher costs. Utility Model Content

[0012] In one optional embodiment, the first fixing fastener includes a first connecting portion, a second connecting portion, a third connecting portion, and a fourth connecting portion. The first connecting portion protrudes from the first mounting surface. The second connecting portion is connected to the end of the first connecting portion away from the first mounting surface and extends circumferentially. The second connecting portion and the first mounting surface form the rotating groove. The third connecting portion is connected to the side of the second connecting portion near the center of the first mounting surface and extends circumferentially. The fourth connecting portion connects the first mounting surface and the third connecting portion. The second connecting portion, the third connecting portion, and the fourth connecting portion form the positioning groove.

[0013] Beneficial effects: When connecting the first cover and the second cover, the second cover is first fastened onto the first cover, so that the first protrusion is embedded in the positioning groove formed by the second connecting part, the third connecting part and the fourth connecting part. Then, the first cover or the second cover is rotated so that the first protrusion enters the rotation groove between the second connecting part and the first mounting surface. The second connecting part and the first mounting surface cooperate to limit the vertical direction of the first protrusion, preventing the second cover from falling off the first cover.

[0014] In one optional embodiment, the first connecting structure further includes a first connecting fastener, and the second connecting structure further includes a second connecting fastener. The first protrusion is located behind the rotating groove, and the second connecting fastener cooperates with the first connecting fastener to prevent the first protrusion from rotating toward the positioning groove.

[0015] Beneficial effects: When connecting the first and second covers, the second cover is first fastened onto the first cover, causing the first protruding tongue to embed into the positioning groove. Then, the first or second cover is rotated, causing the first protruding tongue to enter the rotating groove. The rotating groove limits the vertical movement of the first protruding tongue, preventing the second cover from falling off the first cover. Simultaneously, the second connecting fastener cooperates with the first connecting fastener to prevent the first protruding tongue from rotating towards the positioning groove, thus preventing it from leaving the rotating groove. Therefore, the cooperation of the first and second fixing fasteners, and the cooperation of the first and second connecting fasteners, can secure the connection between the first and second covers in both the circumferential and vertical directions, preventing loosening during use.

[0016] In one optional embodiment, the first connecting fastener is an elastic hook, and the second connecting fastener is a second protrusion disposed on the inner side of the second mounting surface. The first protrusion is located behind the rotating groove, and the elastic hook hooks the second protrusion.

[0017] Beneficial effects: When connecting the first and second covers, the second cover is first fastened onto the first cover, causing the first protruding tongue to embed into the positioning groove. Then, the first or second cover is rotated, causing the first protruding tongue to enter the rotating groove. The rotating groove limits the vertical movement of the first protruding tongue, preventing the second cover from falling off the first cover. Simultaneously, the elastic hook engages the second protruding tongue, preventing it from rotating towards the positioning groove and thus preventing it from leaving the rotating groove. Therefore, the cooperation of the first and second fixing buckles, and the cooperation of the first and second connecting buckles, can secure the connection between the first and second covers in both the circumferential and vertical directions, preventing loosening during use.

[0018] In one optional embodiment, the first connecting fastener includes a fifth connecting portion, a sixth connecting portion, and a seventh connecting portion. The fifth connecting portion protrudes from the first mounting surface. The sixth connecting portion is connected to the top of the fifth connecting portion and extends toward one side of the fifth connecting portion.

[0019] Beneficial effects: When connecting the first cover and the second cover, the second cover is first fastened onto the first cover, so that the first protrusion is embedded in the positioning groove. Then, the first cover or the second cover is rotated so that the first protrusion enters the rotating groove. The rotating groove can limit the vertical movement of the first protrusion, preventing the second cover from falling off the first cover. At the same time, the seventh connecting part undergoes elastic deformation in the direction away from the first mounting surface, causing the second protrusion to pass over the seventh connecting part. After passing over the seventh connecting part, the seventh connecting part returns to its original position and hooks the second protrusion, preventing the first protrusion from rotating in the direction of the positioning groove, thus preventing the first protrusion from leaving the rotating groove.

[0020] In one alternative embodiment, the seventh connecting portion has a guide slope at one end facing the first mounting surface.

[0021] Beneficial effect: By setting a guide slope at the end of the seventh connecting part facing the first mounting surface, when the second cover is rotated, when the second protrusion contacts the guide slope, it will slide relative to the guide slope, causing the seventh connecting part to undergo elastic deformation. After the second protrusion passes the seventh connecting part, the seventh connecting part returns to its original position and hooks the second protrusion, preventing the first protrusion from rotating in the direction of the positioning groove.

[0022] In one optional embodiment, the side of the seventh connecting portion facing the fifth connecting portion is a stop-rotation surface, the angle between the vertical plane perpendicular to the first mounting surface and the stop-rotation surface is α, and the coefficient of friction between the second protruding tongue and the stop-rotation surface is μ, where μ > tanα.

[0023] Beneficial effects: The angle between the vertical plane perpendicular to the first mounting surface and the anti-rotation surface is α, and the coefficient of friction between the second protrusion and the anti-rotation surface is μ, μ>tanα. When the second cover is subjected to a rotational force, the second protrusion cannot disengage from the elastic hook.

[0024] In one alternative embodiment, the second cover and the first cover are sealed together by a first sealing element.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0057] The lid assembly, such as that of an electric kettle, typically consists of a plastic lid and a stainless steel lid. The stainless steel lid comes into direct contact with water vapor, ensuring the kettle meets hygiene requirements. There are various methods for installing the plastic and stainless steel lids. One method involves securing the plastic and stainless steel lids with multiple stainless steel screws, with the screw heads usually located on one side of the stainless steel lid. When the kettle lid is opened, the screw heads are directly visible. This structure has a lower aesthetic appeal, and if the screws and stainless steel lid are not properly sealed, air leakage may occur. Another method involves welding a nut bracket to the stainless steel lid, and then securing a plastic bracket to the nut bracket with screws. Utilizing the elasticity of the plastic lid, the lid is then snapped onto the bracket. This method improves the aesthetic appeal, but it involves more parts, a more complex manufacturing and assembly process, and higher costs.

[0058] The following is combined with Figures 1 to 16 The following describes embodiments of the present invention.

[0059] According to an embodiment of the present invention, a cover assembly is provided, including a first cover 1 and a second cover 2.

Moreover, the total number of parts is only the first cover 1 and the second cover 2. The number of parts is small and the cost is low.

[0062] In one specific embodiment, the second cover 2 is made of food-grade metal, allowing it to come into direct contact with food or water, and as... Figure 2 and Figure 8 As shown, the side of the second cover 2 that comes into contact with food or water has no mounting structure and has an aesthetically pleasing appearance.

[0063] In one embodiment, such as Figure 4 , Figure 5 and Figure 7 The first connecting structure includes a first fixing buckle 102, and a rotating groove 104 is formed between the first fixing buckle 102 and the first mounting surface 101. The second connecting structure includes a second fixing buckle 202, the second mounting surface 201 is an annular surface, and the second fixing buckle 202 is a first protrusion disposed on the inner side of the second mounting surface 201. The first protrusion is adapted to rotate along the rotating groove 104.

[0064] In this embodiment, when connecting the first cover 1 and the second cover 2, the second cover 2 is first fastened onto the first cover 1, and then the first cover 1 or the second cover 2 is rotated so that the first protrusion enters the rotating groove 104. The rotating groove 104 can limit the vertical direction of the first protrusion to prevent the second cover 2 from falling off the first cover 1.

[0065] In one embodiment, a positioning groove 103 is formed between the first fixed buckle 102 and the first mounting surface 101, and the first protrusion is adapted to be embedded in the positioning groove 103 and rotate along the rotating groove 104.

[0066] In this embodiment, when connecting the first cover 1 and the second cover 2, the second cover 2 is first fastened onto the first cover 1, so that the first protrusion is embedded in the positioning groove 103. Then, the first cover 1 or the second cover 2 is rotated so that the first protrusion enters the rotation groove 104, and the positioning groove 103 can be quickly positioned.

[0067] In one embodiment, such as Figure 5 As shown, the first fixing buckle 102 includes a first connecting part 1021, a second connecting part 1022, a third connecting part 1023, and a fourth connecting part 1024. The first connecting part 1021 protrudes from the first mounting surface 101. The second connecting part 1022 is connected to the end of the first connecting part 1021 away from the first mounting surface 101 and extends circumferentially. A rotating groove 104 is formed between the second connecting part 1022 and the first mounting surface 101. The third connecting part 1023 is connected to the side of the second connecting part 1022 near the center of the first mounting surface 101 and extends circumferentially. The fourth connecting part 1024 connects the first mounting surface 101 and the third connecting part 1023. The second connecting part 1022, the third connecting part 1023, and the fourth connecting part 1024 form a positioning groove 103.

[0068] In this embodiment, when connecting the first cover 1 and the second cover 2, the second cover 2 is first fastened onto the first cover 1, so that the first protrusion is embedded in the positioning groove 103 formed by the second connecting part 1022, the third connecting part 1023 and the fourth connecting part 1024. Then, the first cover 1 or the second cover 2 is rotated so that the first protrusion enters the rotation groove 104 between the second connecting part 1022 and the first mounting surface 101. The second connecting part 1022 and the first mounting surface 101 cooperate to limit the vertical direction of the first protrusion, preventing the second cover 2 from falling off the first cover 1.

[0069] In one embodiment, the first connecting structure further includes a first connecting latch 105, and the second connecting structure further includes a second connecting latch 203. The first protrusion is located behind the rotating groove 104, and the second connecting latch 203 cooperates with the first connecting latch 105 to prevent the first protrusion from rotating toward the positioning groove 103.

[0070] In this embodiment, when connecting the first cover 1 and the second cover 2, the second cover 2 is first fastened onto the first cover 1, causing the first protrusion to embed into the positioning groove 103. Then, the first cover 1 or the second cover 2 is rotated, causing the first protrusion to enter the rotation groove 104. The rotation groove 104 can limit the vertical movement of the first protrusion, preventing the second cover 2 from falling off the first cover 1. At the same time, the second connecting fastener 203 cooperates with the first connecting fastener 105 to prevent the first protrusion from rotating towards the positioning groove 103, thus preventing the first protrusion from leaving the rotation groove 104. Therefore, the cooperation of the first fixing fastener 102 and the second fixing fastener 202, and the cooperation of the first connecting fastener 105 and the second connecting fastener 203, can fix the connection between the first cover 1 and the second cover 2 in the circumferential and vertical directions, preventing them from loosening during use.

[0071] In one embodiment, such as Figure 6 , Figure 7 and Figure 16 The first connecting buckle 105 is an elastic hook, and the second connecting buckle 203 is a second protrusion located on the inner side of the second mounting surface 201. The first protrusion is located behind the rotating groove 104, and the elastic hook hooks the second protrusion.

[0072] In this embodiment, when connecting the first cover 1 and the second cover 2, the second cover 2 is first fastened onto the first cover 1, causing the first protrusion to embed into the positioning groove 103. Then, the first cover 1 or the second cover 2 is rotated, causing the first protrusion to enter the rotation groove 104. The rotation groove 104 can limit the vertical movement of the first protrusion, preventing the second cover 2 from falling off the first cover 1. At the same time, the elastic hook catches the second protrusion, preventing it from rotating towards the positioning groove 103, thus preventing the first protrusion from leaving the rotation groove 104. Therefore, the cooperation of the first fixing buckle 102 and the second fixing buckle 202, and the cooperation of the first connecting buckle 105 and the second connecting buckle 203, can fix the connection between the first cover 1 and the second cover 2 in the circumferential and vertical directions, preventing them from loosening during use.

[0073] In one embodiment, the first connecting fastener 105 includes a fifth connecting portion 1051, a sixth connecting portion 1052, and a seventh connecting portion 1053. The fifth connecting portion 1051 protrudes from the first mounting surface 101. The sixth connecting portion 1052 is connected to the top of the fifth connecting portion 1051 and extends toward one side of the fifth connecting portion 1051. The seventh connecting portion 1053 is connected to the end of the sixth connecting portion 1052 away from the fifth connecting portion 1051 and extends toward the first mounting surface 101. The seventh connecting portion 1053 has a gap with the first mounting surface 101. The first protrusion is located behind the rotating groove 104, and the seventh connecting portion 1053 hooks the second protrusion.

[0074] In this embodiment, when connecting the first cover 1 and the second cover 2, the second cover 2 is first fastened onto the first cover 1, so that the first protrusion is embedded in the positioning groove 103. Then, the first cover 1 or the second cover 2 is rotated so that the first protrusion enters the rotating groove 104. The rotating groove 104 can limit the vertical direction of the first protrusion to prevent the second cover 2 from falling off the first cover 1. At the same time, the seventh connecting part 1053 undergoes elastic deformation in the direction away from the first mounting surface 101, so that the second protrusion passes over the seventh connecting part 1053. After passing over the seventh connecting part 1053, the seventh connecting part 1053 returns to its original position and hooks the second protrusion, preventing the first protrusion from rotating in the direction of the positioning groove 103, thus preventing the first protrusion from leaving the rotating groove 104.

[0075] Specifically in one embodiment, such as Figure 4 As shown, along the circumferential direction, the first connecting buckle 105 is located between two first fixing buckles 102, and the sixth connecting portion 1052 of the first connecting buckle 105 extends toward the first connecting portion 1021 of one of the first connecting buckles 105.

[0076] In one embodiment, the seventh connecting portion 1053 has a guide slope 10531 at one end facing the first mounting surface 101.

[0077] In this embodiment, by providing a guide slope 10531 at one end of the seventh connecting part 1053 facing the first mounting surface 101, when the second cover 2 is rotated, when the second protrusion contacts the guide slope 10531, it will slide relative to the guide slope 10531, causing the seventh connecting part 1053 to undergo elastic deformation. After the second protrusion passes the seventh connecting part 1053, the seventh connecting part 1053 returns to its original position and hooks the second protrusion, preventing the first protrusion from rotating toward the positioning groove 103.

[0078] In one embodiment, such as Figure 16 As shown, the side of the seventh connecting part 1053 facing the fifth connecting part 1051 is a stop surface 10532. The angle between the vertical plane 3 perpendicular to the first mounting surface 101 and the stop surface 10532 is α. The coefficient of friction between the second convex tongue and the stop surface 10532 is μ, where μ > tanα.

[0079] In this embodiment, the angle between the vertical plane 3 perpendicular to the first mounting surface 101 and the anti-rotation surface 10532 is α, and the coefficient of friction between the second protrusion and the anti-rotation surface 10532 is μ, μ>tanα. When the second cover 2 is subjected to a rotational force, the second protrusion cannot disengage from the elastic hook.

[0080] Specifically, assuming the rotational force is F, the normal force of the second tongue on the anti-rotation surface 10532 is N, the resultant force of F and N is F1, F1 = N * tanα, the frictional resistance between the second tongue and the anti-rotation surface 10532 is f, and the coefficient of friction is μ. To ensure that it cannot detach, f > F1 must be satisfied, then N * μ > N * tanα, therefore the result is μ > tanα.

[0081] In one embodiment, the second cover 2 and the first cover 1 are sealed together by a first sealing member 4.

[0082] In this embodiment, the second cover 2 and the first cover 1 are sealed together by the first sealing member 4, which can prevent water or foreign objects from entering the space between the first cover 1 and the second cover 2.

[0084] In this embodiment, by providing an installation groove 108 in the first cover 1, the positioning and installation of the first sealing element 4 is facilitated.

[0085] Specifically, the first sealing element 4 is located in the mounting groove 108 and a portion of it is exposed. After the first cover 1 and the second cover 2 are assembled, the first sealing element 4 abuts against the second cover 2.

[0086] The first sealing element 4 is specifically an O-ring.

[0087] In one embodiment, the second cover 2 has a working surface 207 and a flange 208. The flange 208 is folded inward from the edge of the working surface 207 on the back side of the working surface 207 to form a second mounting surface 201. The flange 208 abuts against the first seal 4.

[0088] Beneficial effects: The flange 208 is folded inward from the edge of the working surface 207 on the back side of the working surface 207 to form the second mounting surface 201. The structure is simple, and the flange 208 abuts against the first sealing member 4, which can effectively prevent water or foreign objects from entering the space between the first cover 1 and the second cover 2.

[0089] In one embodiment, the first cover 1 is a plastic cover, and the second cover 2 is a stainless steel cover.

[0090] In this embodiment, the second cover 2 is a stainless steel cover, and the working surface 207 of the second cover 2 can come into contact with food or water, making it more hygienic.

[0091] In one embodiment, the second cover 2 has a working surface 207, which is integrally formed by stamping with the second mounting surface 201, or the working surface 207 and the second mounting surface 201 are connected together by welding or riveting.

[0092] In this embodiment, the working surface 207 and the second mounting surface 201 are integrally formed by stamping, or the working surface 207 and the second mounting surface 201 are connected together by welding or riveting. The structure of the second cover 2 is simple and the number of overall parts is small.

The first cover 1 is provided with a water inlet hole 106; the second cover 2 is connected to the first cover 1, and one of the second cover 2 and the first cover 1 is provided with a cylindrical member 204, and the other of the second cover 2 and the first cover 1 abuts against the cylindrical member 204. The inner side of the cylindrical member 204 forms a water inlet channel 2041, which is connected to the water inlet hole 106; the magnet 5 surrounds the cylindrical member 204; the sealing structure 6 seals the upper and lower sides and the outer side of the magnet 5, and the sealing structure 6 is in sealing contact with the cylindrical member 204.

[0094] In this embodiment, since the second cover 2 and the other one of the first cover 1 abut against the cylindrical member 204, water can be prevented from entering the space between the first cover 1 and the second cover 2. Since the sealing structure 6 seals the upper and lower sides and the outer side of the magnet 5, it can protect the upper and lower sides and the outer side of the magnet 5. Since the sealing structure 6 is in sealed contact with the cylindrical member 204, water can be prevented from flowing to the inner surface of the magnet 5 through the gap between the sealing structure 6 and the cylindrical member 204. Therefore, the magnet 5 can be prevented from rusting, ensuring the magnetic attraction of the magnet 5.

[0095] In one specific embodiment, the cylindrical member 204 is disposed on the second cover 2, and the cylindrical member 204 abuts against the first cover 1.

[0098] In one embodiment, the sealing structure 6 is provided with a first annular rib 601, which abuts against the cylindrical member 204.

[0099] In this embodiment, by providing a first annular rib 601 in the sealing structure 6, which abuts against the cylindrical member 204, the seal between the sealing structure 6 and the cylindrical member 204 can be further ensured, preventing water from flowing to the inner surface of the magnet 5 through the gap between the sealing structure 6 and the cylindrical member 204. Therefore, the magnet 5 can be further prevented from rusting, ensuring the magnetic attraction of the magnet 5.
