Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to an electric hot pot. Background Art

[0002] Existing electric hot pot products, such as conventional rice cookers and electric pressure cookers, have lids that are assembled in two ways: one-piece and two-piece. The lid of a two-piece electric hot pot can be removed from the pot body to open the pot body; the lid of a one-piece electric hot pot is rotatably connected to the pot body so that the lid can be flipped up and down around the connection to open and close the lid.

[0003] For one-piece electric hot pots, a torsion spring is usually set at the connection between the pot lid and the pot body. When the user presses the lid-opening button to unlock the pot body, the pot lid will bounce upward under the elastic force of the torsion spring and automatically perform the lid-opening action. The lid-closing action requires the user to press the pot lid by hand to overcome the resistance of the torsion spring to close the lid.

[0004] The torsion spring structure not only creates excessive spring force during lid opening, but also creates a significant force on the lid's upward tilt. Consequently, when the lid reaches the end of its upward travel, it suddenly hits a stop, causing some wobbling and even tipping over the pot. During lid closing, the user must constantly apply significant force to overcome the spring's force, making it inconvenient. If the lid closing damping were removed, the lid would snap shut under its own weight, colliding violently with the pot, creating unusual noises and possibly causing damage.

[0005] In addition, the lid and the pot body are provided with a hole for installing a rotating shaft. The rotating shaft passes through the hole to connect the two in series, and a torsion spring is sleeved on the rotating shaft. The tail end of the torsion spring is fixed in the pot body, and the front end of the torsion spring is inserted into the pot lid. The pot body is provided with a hinged boss, and the torsion spring is accommodated in the hinged boss. This assembly method not only has more accessories, but also is more complicated to assemble. Because the torsion spring applies force to the pot body and the lid at the same time, the structural and material strength requirements of the pot lid and the pot body are relatively high, resulting in a surge in costs. In addition, the torsion spring has a fatigue life. After a long time, the torsion spring force decays and may not be enough to open the pot lid, so the pot lid still needs to be opened by hand. In addition, the torsion spring force is relatively large, which will cause deformation of the pot lid and the pot body.

[0006] Furthermore, the outer side of the hinged boss needs to reserve an avoidance hole for torsion spring deformation, which is used to avoid the torsion spring leg when opening and closing the lid. The power board is installed below the torsion spring on the pot body. During daily use or safety testing, there is a possibility of water entering the avoidance hole. Once water enters the hinged boss from the avoidance hole, it will drip onto the power board, increasing the risk of water damage to the power board. Utility Model Content

[0007] The utility model provides an electric hot pot to solve the problems that a one-piece electric hot pot uses a torsion spring structure to open and close the lid, which is inconvenient to use, complicated to assemble, and has a short service life. In addition, the arrangement of the torsion spring avoidance hole on the outer surface of the hinged boss may cause water to enter, thereby increasing the risk of damage to the power board.

[0008] The technical solution adopted by this utility model is:

[0009] An electric hot pot comprises a pot body and a pot cover rotatably connected to the pot body, the pot body being provided with an upwardly protruding connecting boss, the pot cover being provided with a notch matching the connecting boss, the pot cover being fixed to the connecting boss via the notch, the connecting boss having two side walls rotatably matching the pot cover, a rotatable damper being provided between at least one of the side walls and the pot cover; the connecting boss also having an exposed rear wall, the rear wall being closed to match the outer surface of the pot body.

[0010] The electric hot pot of the present invention also has the following additional technical features:

[0011] The damper has a fixed part and a rotating part. The fixed part is located inside the connecting boss, and the rotating part extends from the side wall to cooperate with the pot cover. The pot cover can drive the rotating part to rotate relative to the fixed part. When the rotating part rotates in a first direction relative to the fixed part, it is subjected to a rotational damping force. The first direction is the direction in which the pot cover is closed.

[0012] The damper comprises a fixed part and a rotating part, wherein the fixed part is located inside the pot cover, and the rotating part extends from the groove wall of the notch to cooperate with the connecting boss.

[0013] The surface where the rear wall is located is flush with the outer surface of the pot body.

[0014] A dividing rib is provided inside the connecting boss, which divides the inside of the connecting boss into an installation cavity and a wire passing cavity. Part of the damper is fixed in the installation cavity. The connecting boss has a top wall, and a wire passing opening is provided on the top wall corresponding to the wire passing cavity.

[0015] A limiting rib is arranged in the installation cavity. The limiting rib is located above the damper and is provided with a stop surface that is adapted to the shape of the damper.

[0016] The pot cover comprises a lining cover and a surface cover. A first connecting arm is provided on the outer peripheral side of the lining cover. The first connecting arm is located on one side of the connecting boss and is provided with a matching groove for matching with the damper.

[0017] The electric heating pot further comprises a connecting piece which is fixed to the outer peripheral side of the lining cover to form a first connecting arm, and a matching groove is arranged on the connecting piece.

[0018] A second connecting arm is further provided on the outer peripheral side of the lining cover. The first connecting arm and the second connecting arm are spaced apart along the circumference of the pot cover, and a gap is formed between the first connecting arm and the second connecting arm.

[0019] The pot body comprises an outer cover, and the lower side of the connecting boss is provided with a downwardly protruding limiting rib, and the limiting rib is located on the outer side of the outer cover.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0021] 1. In the present invention, a damper is provided at the mating position between the connecting boss and the notch in the pot lid. The damper's own damping action is utilized to provide a damping force to the pot lid during rotation. This not only simplifies the number of components and structural complexity of the connection and damping structures, but also simplifies the damping force of the damper, which is generated between the rotating portion and the fixed portion and does not directly exert force on the pot body and pot lid. This reduces the stress on the pot lid and pot body, significantly lowering the structural strength requirements for both, and thus saving material costs. Furthermore, the damper has a much longer fatigue life than a torsion spring, thus being able to continuously and reliably apply rotational damping to the pot lid.

[0022] Furthermore, since the damper does not deform during the application of the damping force, the fixed portion of the damper can be completely housed within the connecting boss or pot lid, sealing the rear wall of the connecting boss so that the outer wall of the connecting boss is free of holes. This prevents liquid from entering the pot from the outer side of the connecting boss during both daily use and safety testing. This ensures the cleanliness of the pot while significantly reducing the risk of water damage to the power board below the connecting boss, thereby improving the reliability and service life of the electric hot pot. Furthermore, the rear wall of the connecting boss mates with the outer surface of the pot, eliminating the need for an additional cover plate structure on the outside. This simplifies the structure and assembly difficulty of the electric hot pot, saving costs while ensuring the appearance quality.

[0023] 2. As a preferred embodiment of the present invention, the damper comprises a fixed portion and a rotating portion. When the rotating portion rotates relative to the fixed portion in a first direction, it is subjected to a rotational damping force. The first direction is the direction in which the lid closes. The lid can be flipped upward about its connection to open and downward to close. The damper is configured to provide a damping force in the closing direction. When opening the lid, the user must actively flip the lid upward. Since this process is entirely user-initiated, the user can adjust the force applied to tilt the lid, thereby alleviating the problem of excessive upward tilting force causing the lid to wobble. When closing the lid, the user does not need to continuously apply downward pressure; instead, they simply push the lid downward. The lid automatically closes slowly under the influence of its own weight and the damping force of the damper. The damping force also prevents the lid from colliding with the pot at high speed, thereby reducing the risk of noise and damage from collisions. This makes opening and closing the lid simpler, more convenient, and more labor-saving, improving the user experience.

[0024] 3. As a preferred embodiment of the present invention, a dividing rib is provided inside the connecting boss, and the dividing rib divides the inside of the connecting boss into an installation cavity and a wire passing cavity. Part of the area of the damper is located in the installation cavity, and the connecting boss has a top wall, and a wire passing opening is provided on the top wall corresponding to the wire passing cavity. The dividing rib divides the inside of the connecting boss into two chambers, wherein the installation cavity is used to install the damper, and the wire passing cavity is used for wiring, so that electrical components such as the display panel on the pot cover are electrically connected to the power board on the pot body. The connecting boss realizes the integration of wiring and installation functions, which is multi-purpose and saves costs. At the same time, the wires pass through the inside of the connecting boss, which not only realizes hidden wiring and improves the appearance, but also avoids the risk of the guide wire coming into contact with water.

[0025] 4. As a preferred embodiment of the present invention, the pot cover includes a lining cover and a surface cover. A first connecting arm is provided on the outer peripheral side of the lining cover. The first connecting arm is located on one side of the connecting boss. The first connecting arm is provided with a matching groove for matching with the damper. The damper is provided inside the connecting boss, and the rotating part extends out of the connecting boss and is located in the notch. The matching groove of the first connecting arm provided on the lining cover matches the rotating part, so that the rotating part can be driven to rotate synchronously when the pot cover is flipped up and down to achieve a damping effect. The first connecting arm is provided on the lining cover and is located on the inner side of the surface cover, so that the surface cover can block the connection structure between the lining cover and the damper, realizing a hidden design without being exposed, thereby ensuring aesthetics.

[0026] 5. As a preferred embodiment of the present invention, the pot body includes an outer cover, and the underside of the connecting boss is provided with a downwardly projecting retaining rib, located on the outer side of the outer cover. The retaining rib extends downward and is located on the outer side of the outer cover. During assembly, the retaining rib helps position the outer cover, reducing assembly difficulty. Furthermore, after assembly, the retaining rib also acts as a retaining force on the outer cover, preventing partial outward deformation. Furthermore, the outer cover may exhibit cosmetic defects such as connecting lines during the molding process (for example, in an injection-molded plastic cover, a vertical joining line is formed where two streams of plastic meet after injection; or in a metal cover, a vertical connecting line is formed at the joint when the cover is formed by end-to-end connection). The retaining rib can conceal the upper end of the connecting line, improving the appearance while preventing scratches from the user's hand. It also prevents the end of the connecting line from deforming and bulging outward, reducing deformation of the outer cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0046] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0047] like Figure 1 、 Figure 2 As shown, an electric hot pot includes a pot body 1 and a pot cover 2 rotatably connected to the pot body 1, the pot body 1 is provided with an upwardly protruding connecting boss 13, the pot cover 2 is provided with a notch 221 that matches the connecting boss 13, and the pot cover 2 is fixed to the connecting boss 13 through the notch 221, the connecting boss 13 has two side walls 132 that rotatably cooperate with the pot cover 2, and a rotatable damper 3 is provided between at least one side wall 132 and the pot cover 2; the connecting boss 13 also has an exposed rear wall 131, and the rear wall 131 is closed to adapt to the outer surface of the pot body 1.

[0048] It should be noted that the present invention does not limit the type of electric heating cooker. It can be a normal pressure electric heating cooker, such as an electric rice cooker, an electromagnetic heating cooker, etc., or a pressure electric heating cooker, such as an electric pressure cooker, an electromagnetic pressure cooker, etc., as long as the lid 2 is rotatably connected to the pot body 1. At the same time, the electric heating cooker of the present invention can be of various models, capacities, shapes, etc.

[0049] Preferably, the damper 3 is a common damper 3 available on the market, comprising a fixed portion 31 and a rotating portion 32. The fixed portion 31 is fixed within the connecting boss 13 and cannot move, and the pot lid 2 cooperates with the rotating portion 32 to drive the rotating portion 32 to rotate synchronously. When the rotating portion 32 rotates relative to the fixed portion 31, the rotating portion 32 is subjected to a damping force, thereby damping the opening and / or closing movement of the pot lid 2.

[0050] In the present invention, a damper 3 is provided at the connection between the connecting boss 13 and the pot lid 2. The damping effect of the damper 3 itself is utilized to provide a damping force when the pot lid 2 rotates. This not only simplifies the number of components and structural complexity of the connection structure and the damping structure. Furthermore, the damping force of the damper 3 is generated between the rotating portion 32 and the fixed portion 31, and does not directly exert a force on the pot body 1 and the pot lid 2. This reduces the forces acting on the pot lid 2 and the pot body 1, significantly lowering the structural strength requirements for both, thereby saving material costs. Furthermore, the fatigue life of the damper 3 is much greater than that of a torsion spring, and therefore it can continuously and reliably apply rotational damping to the pot lid 2.

[0051] Furthermore, since the damper 3 does not deform during the application of the damping force, the fixing portion 31 of the damper 3 can be completely accommodated within the connecting boss 13. A rear wall 131 is provided on the outer side of the connecting boss 13 to completely seal the outer side of the connecting boss 13, leaving no holes on the outer side. This allows no liquid to enter the pot body 1 from the outer side of the connecting boss 13, both during daily use and during safety testing. This ensures the cleanliness of the pot body 1 and greatly reduces the risk of water damage to the power board below the connecting boss 13, thereby improving the reliability and service life of the electric hot pot. Furthermore, the rear wall 131 of the connecting boss 13 is compatible with the outer surface of the pot body 1, eliminating the need for an additional cover structure on the outside. This simplifies the structure and assembly difficulty of the electric hot pot, saves costs, and ensures the appearance quality.

[0052] Specifically, the connecting boss 13 is adapted to the outer surface of the pot body. In a preferred embodiment, as shown in FIG. Figure 3As shown, the surface of the rear wall 131 is flush with the outer surface of the pot body 1, so that the rear wall 131 constitutes the appearance of the electric hot pot and has no step difference with the pot body 1, thereby improving the smoothness of the appearance. Of course, in another embodiment, the surface of the rear wall 131 can also be not flush with the pot body 1, but have a certain step difference. In this case, there is no need to set an additional cover plate on the outside of the rear wall 131 to ensure the appearance of the electric hot pot.

[0053] It is understood that the connecting boss 13 is provided on one side of the pot body 1, and the rear wall 131 is the side thereof facing away from the center of the pot body 1. In addition, the rear wall 131 has side walls 132 on both sides thereof that are perpendicular to the rear wall 131, an inner side wall located on the inner side of the connecting boss 13, and a top wall 133 located on the top of the connecting boss 13. The rear wall 131 and the top wall 133 may be perpendicular or at other angles, or the rear wall 131 may transition to the top wall 133 via a curved surface or an inclined surface, that is, the top wall 133 and the rear wall 131 may be a curved surface structure as a whole, which is not limited here.

[0054] The present invention does not limit the location of the damper 3, which can be one of the following embodiments:

[0055] Implementation method 1: In this implementation method, Figure 3 、 Figure 4 As shown, the damper 3 has a fixed portion 31 and a rotating portion 32 . The fixed portion 31 is located inside the connecting boss 13 , and the rotating portion 32 extends from the side wall 132 to cooperate with the pot cover 2 . The pot cover 2 can drive the rotating portion 32 to rotate relative to the fixed portion 31 .

[0056] Embodiment 2: In this embodiment, the damper 3 has a fixed portion 31 and a rotating portion 32 . The fixed portion 31 is located inside the pot cover 2 , and the rotating portion 32 extends from the groove wall of the notch 221 to cooperate with the connecting boss 13 .

[0057] It should be noted that the present invention does not limit the damping direction of the damper 3. In a preferred embodiment, the rotating part 32 is subjected to a rotational damping force when rotating relative to the fixed part 31 in a first direction, and the first direction is the direction in which the pot cover 2 is closed.

[0058] The pot lid 2 can be flipped upward around the connection to open the lid, and flipped downward to close the lid. The damper 3 is configured to provide a damping force in the closing direction. When the user opens the lid, the user needs to carry the pot lid 2 and actively flip it upward to open it. Since this process is completely operated by the user, the user can subjectively adjust the force of flipping the pot lid 2, thereby alleviating the problem of the pot lid 2 shaking due to excessive upward flipping force. When closing the lid, the user does not need to continuously apply downward pressure to the pot lid 2. The user only needs to gently push the pot lid 2 downward. The pot lid 2 can automatically and slowly close under the action of its own gravity and the damping force of the damper 3. Due to the existence of the damping force, the pot lid 2 will not collide with the pot body 1 at a relatively fast speed, thereby reducing the risk of abnormal noise and collision damage. This makes the user's opening and closing operations simpler, more convenient and more labor-saving, improving the user experience.

[0059] Of course, in other embodiments, the damper 3 can also be designed as a two-way damper for opening and closing the lid, that is, when the user flips the lid open, it is also subjected to a damping force, and the user needs to use greater force to flip the pot lid 2 open.

[0060] The present invention does not limit the installation method of the damper 3. As a preferred embodiment of the present invention, Figure 2 As shown, the rear wall 131 is located on the side of the connecting boss 13 away from the center of the pot body 1. The connecting boss 13 also has side walls 132 located on both sides of the rear wall 131. One of the side walls 132 is provided with a mounting opening, and the other side wall 132 is provided with a through opening 1321 for the rotating part 32 to extend out. The damper 3 is installed to the inside of the connecting boss 13 from the mounting opening.

[0061] The damper 3 extends along its axis from one side of the connecting boss 13, eliminating the need for a hole in the rear wall 131 and simplifying the installation steps for the damper 3, reducing assembly difficulty and improving assembly efficiency. Furthermore, the lid 2 is provided with connecting arms on either side of the connecting boss 13. After the lid 2 and the pot body 1 are assembled, the connecting arms block and conceal the openings in the side walls 132. This not only prevents the openings in the side walls 132 from appearing on the exterior of the electric hot pot, but also reduces the risk of liquid entering the pot body 1 through the openings in the side walls 132.

[0062] Specifically, Figure 2 、 Figure 3 、 Figure 4For example, the sidewall 132 on the left side of the connecting boss 13 defines a mounting opening, and the sidewall on the right side defines a through-opening 1321. When installing the damper 3, the rotating portion 32 is oriented to the right, and the damper 3 is inserted into the interior of the connecting boss 13 from the mounting opening. This allows the rotating portion 32 to extend from the through-opening 1321 on the right side, while the fixed portion 31 is located within the connecting boss 13. Specifically, the width of the rotating portion 32 is smaller than that of the fixed portion 31, and the diameter of the through-opening 1321 is larger than the width of the rotating portion 32 but smaller than the width of the fixed portion 31, so that the fixed portion 31 cannot pass through the through-opening 1321. This allows the connecting arm on the right side of the connecting boss 13 on the pot lid 2 to cooperate with the rotating portion 32.

[0063] Of course, the damper 3 can also be installed inside the connecting boss 13 in other ways, such as installing it from the bottom of the connecting boss 13 to the inside of the connecting boss 13, or setting the top wall 133 of the connecting boss 13 to a removable structure so that the top cover of the connecting boss 13 can be opened for installing the damper 3.

[0064] Furthermore, if Figure 5 、 Figure 6 As shown, a fastening portion 138 is provided inside the connecting boss 13 , and the fastening portion 138 is fixedly connected to the fixing portion 31 to limit the rotation of the fixing portion 31 .

[0065] By locking and fixing the fastening portion 138 with the fixing portion 31 , the fixing portion 31 is locked inside the connecting boss 13 and will not be affected by the rotating portion 32 and rotate, thereby providing a stable damping force for the rotating portion 32 .

[0066] Preferably, if Figure 6 As shown, the fastening portion 138 is a fixing column disposed within the connecting boss 13, and the fixing portion 31 is provided with a fixing rib. Both the fixing column and the fixing rib have openings, and the two are fastened together by fasteners such as screws. Of course, the fastening portion 138 and the fixing portion 31 can also be fastened together by other means such as snap-fitting, which is not limited here.

[0067] In a preferred embodiment, Figure 6 As shown, a dividing rib 139 is provided inside the connecting boss 13, and the dividing rib 139 divides the inside of the connecting boss 13 into a mounting cavity 136 and a wire passing cavity 137. The fixing portion 31 of the damper 3 is located in the mounting cavity 136. The connecting boss 13 has a top wall 133, and the top wall 133 has a wire passing opening 134 corresponding to the wire passing cavity 137.

[0068] Separating ribs 139 divide the interior of connecting boss 13 into two chambers: mounting chamber 136 for mounting damper 3, and wiring chamber 137 for routing wiring, electrically connecting electrical components such as the display panel on lid 2 to the power board on pot body 1. Connecting boss 13 integrates wiring and mounting functions, achieving multiple uses and saving costs. Furthermore, the wires pass through connecting boss 13, concealing the wiring and improving the aesthetics while also preventing the risk of the guide wires coming into contact with water.

[0069] Specifically, such as Figure 6 As shown, a fastening portion 138 for fastening to the fixing portion 31 is provided inside the connecting boss 13, for example Figure 5 In the fixing column shown in FIG, the separation rib 139 passes through the fastening portion 138 so that the separation rib 139 also plays a structural reinforcement role, thereby improving the structural strength of the fastening portion 138.

[0070] Furthermore, if Figure 6 As shown, a limiting rib 1391 is provided in the installation cavity 136 . The limiting rib 1391 is located above the fixing portion 31 and is provided with a stop surface 1392 that is adapted to the shape of the fixing portion 31 .

[0071] After the damper 3 is installed, the limiting rib 1391 acts as a limit to the fixing portion 31 and can press the fixing portion 31 to make it more secure. The stop surface 1392 is adapted to the shape of the fixing portion 31, so that the contact between the two is closer, thereby improving the limiting effect. Specifically, Figure 6 As shown, the upper surface of the fixing portion 31 is a curved surface structure, and the stop surface 1392 is also a curved surface structure. Of course, the bottom wall of the installation cavity 136 can also be provided with a supporting structure, and the supporting surface is adapted to the shape of the fixing portion 31, so that the supporting structure and the limiting ribs 1391 clamp the fixing portion 31 from top to bottom.

[0072] Preferably, if Figure 6 As shown, a plurality of limiting ribs 1391 are arranged at intervals along the length direction of the damper 3.

[0073] As a preferred embodiment, Figure 2 、 Figure 4 、 Figure 6 As shown, the pot cover 2 includes a surface cover 22 and a lining cover 21 . A first connecting arm is provided on the outer peripheral side of the lining cover 21 . The first connecting arm is located on one side of the connecting boss 13 . The first connecting arm is provided with a matching groove 41 for matching with the rotating part 32 .

[0074] The damper 3 is disposed within the connecting boss 13, with the rotating portion extending from the connecting boss 13 and positioned within the notch 221. The mating groove 41 of the first connecting arm provided on the lining cover 21 engages with the rotating portion 32, allowing the rotating portion 32 to rotate synchronously when the pot lid 2 is flipped up and down, thereby achieving a damping effect. The first connecting arm is provided on the lining cover 21, located inside the top cover 22. This allows the top cover 22 to conceal the connection structure between the lining cover 21 and the damper 3, achieving a concealed design without being exposed, thereby ensuring aesthetics.

[0075] Furthermore, the matching groove 41 has an opening facing downward, so that the rotating portion 32 enters the matching groove 41 through the opening.

[0076] The pot cover 2 and the rotating part 32 are linked by the matching groove 41 and the rotating part 32. The opening of the matching groove 41 faces downward, so that the lining cover 21 can be installed from top to bottom without being axially sleeved on the rotating part 32 along the damper 3, thereby greatly saving installation space and improving assembly convenience.

[0077] Preferably, if Figure 2 As shown, the cross-section of the rotating portion 32 is non-circular, and the shape of the mating groove 41 is adapted to it, thereby enabling a better engagement between the two and preventing relative rotation between them. Specifically, the rotating portion 32 has straight walls on opposite sides, and the two corresponding groove walls of the mating groove 41 are also straight walls. Of course, the cross-section of the rotating portion 32 can also have other shapes, such as triangle, quadrilateral, pentagon, hexagon, etc.

[0078] It should be noted that the present invention does not limit the structure of the first connecting arm. In one embodiment, the first connecting arm is a rib protruding outward from the two sides of the pot cover, and the matching groove 41 is opened on the rib. In another embodiment, Figure 2 、 Figure 4 、 Figure 6 As shown, the electric hot pot further includes a connecting piece 4 , which is fixed to the outer peripheral side of the pot cover 2 to form a first connecting arm, and a matching groove 41 is provided on the connecting piece 4 .

[0079] In this embodiment, a separate component is connected to the lining cover 21 to form a first connecting arm, so that the first connecting arm can be made of a material different from the pot cover 2. The lining cover 21 is usually made of plastic, while the first connecting arm can be made of a stronger material, such as metal.

[0080] Specifically, the connecting member 4 can be fixed to the pot cover 2 by screws or the like.

[0081] Furthermore, if Figure 2 、 Figure 4 、 Figure 6As shown, a second connecting arm 212 is further provided on the outer peripheral side of the pot cover 2. The first connecting arm and the second connecting arm 212 are spaced apart along the circumference of the pot cover 2, and a gap 221 is formed between the two. The surface cover 22 is provided with a groove corresponding to the gap 221, and the connecting boss 13 is located in the gap 221.

[0082] The first and second connecting arms 212 are located on the left and right sides of the connecting boss 13, which not only makes the connection structure between the pot cover 2 and the pot body 1 more compact, but also blocks the openings on the left and right sides of the connecting boss 13 to prevent water from entering. The damper 3 can cooperate with the first connecting arm on one side, or by providing two dampers 3 or providing a rotating portion 32 on each side of the damper 3, so that both the first and second connecting arms 212 cooperate with the rotating portion 32, thereby improving the stability of the damping.

[0083] Preferably, if Figure 1 、 Figure 7 As shown, the pot body 1 includes an outer cover 11 and a water collecting ring 12 placed above the outer cover 11. The upper surface of the water collecting ring 12 is provided with a water collecting groove 121 for collecting liquid dripping from the pot cover 2. The connecting boss 13 is provided at the tail of the water collecting ring 12 (the side away from the user when in use). The water collecting ring 12 is gradually lowered toward the connecting boss 13 in the left and right areas of the connecting boss 13, so that the liquid in the water collecting groove 121 can flow down from the rear side of the pot body 1.

[0084] like Figure 1 、 Figure 2 As shown, the pot cover 2 includes a lining cover 21 and a surface cover 22 located on the outside of the lining cover 21. The lining cover 21 cooperates with the rotating part 32. A retaining rib 211 is provided on the lower edge of the lining cover 21. The connecting arm is located on the upper side of the retaining rib 211, so that the matching position of the connecting arm and the connecting boss 13 is located above the retaining rib 211. The retaining rib 211 can block the liquid in the water collecting tank 121, so that it cannot reach the matching position above, thereby further preventing the liquid from entering the interior of the pot body 1.

[0085] Preferably, if Figure 9 As shown, the pot body 1 includes an outer cover 11 , and a downwardly protruding limiting rib 14 is provided on the lower side of the connecting boss 13 . The limiting rib 14 is located on the outer side of the outer cover 11 .

[0086] The retaining rib 14 extends downward and is located outside the outer cover 11. During assembly, the retaining rib 14 helps position the outer cover 11, reducing assembly difficulty. After assembly, the retaining rib 14 also limits the outer cover 11, preventing it from partially bulging outward. Furthermore, the outer cover 11 may exhibit cosmetic defects such as connecting lines during the molding process (for example, in an injection-molded plastic outer cover 11, a vertical connecting line is formed where the two plastic strands meet after the plastic enters the injection port; or in a metal outer cover 11, a vertical connecting line is also formed at the joint when the end-to-end connection is formed). The retaining rib 14 can conceal the upper end of the connecting line, improving its aesthetics while also preventing scratches from the user's hand. It also prevents the end of the connecting line from deforming and bulging outward, reducing deformation of the outer cover 11.

[0087] Specifically, such as Figure 9 As shown, the pot body 1 further includes a water collecting ring 12 located above the outer cover 11 , the connecting boss 13 is located on the upper side of the water collecting ring 12 , and the limiting rib 14 is located on the lower side of the water collecting ring 12 .

[0088] Preferably, a convex hump is provided on the rear side of the pot body 1, the connecting boss 13 is provided on the top surface of the convex hump, and the pot cover 2 is provided with a corresponding convex hump, so that the overall shape of the electric hot pot is more rounded.
