[0019] Due to the adoption of the above technical scheme, the utility model has the beneficial effects as follows:

[0020] 1. In this utility model, the locking component is rotatably connected to the cover, allowing it to rotate relative to the cover to lock or unlock the inner cover. Compared to sliding, the rotational method restricts the movement of the locking component to the pivot point, limiting it to oscillation around that pivot. This makes the movement trajectory of the locking component more reliable and stable, reducing shaking during movement. The electrical mounting space between the cover and the top cover is used to install electrical components such as the display panel. Because the oscillation of the locking component is more stable and requires less space, there is no need to leave a gap between the cover plate and the cover. This allows the cover plate to seal the top opening of the mounting cavity, improving the contact effect between the cover plate and the cover, thus enhancing the sealing performance. When the cover is opened, even if steam from inside the pot rushes into the mounting cavity, it cannot reach the electrical safety space above the cover due to the obstruction of the cover plate. This ensures the cleanliness of the upper side of the cover, preventing dirt accumulation, and also prevents steam from contacting the functional components and electrical components on the upper side of the cover, ensuring the service life of each component.

[0021] 2. In a preferred embodiment of this utility model, the locking component includes a connecting portion and a limiting portion located below the connecting portion. The connecting portion is rotatably connected to the cover. The limiting portion has a vertical limiting surface and a horizontal limiting surface. A fixing portion is provided on the edge of the inner cover. The vertical limiting surface abuts against the outer edge of the fixing portion, and the horizontal limiting surface is located below the fixing portion to abut against the lower side of the fixing portion. The limiting portion is located below the connecting portion so that it can swing towards and away from the center of the cover with the connecting portion as the center. When the limiting portion moves towards the center of the cover, it cooperates with the fixing portion to lock the inner cover onto the cover. When the limiting portion moves away from the center of the cover, it disengages from the fixing portion and releases the inner cover. The horizontal limiting surface is located below the fixing portion, forming a downward limiting on the inner cover, preventing the inner cover from falling off the cover and ensuring the fixing effect of the inner cover, while also restricting the inner cover from shaking in the vertical direction. When the vertical limiting surface abuts against the outer edge of the fixing part, it can play a lateral limiting role for the inner cover, keeping the inner cover centered relative to the cover body, preventing the inner cover from shaking horizontally, making the inner cover installation more stable, and thus ensuring the stability of the seal.

[0022] 3. As a preferred embodiment of the utility model, the locking piece further comprises a buckling part below the limiting part, the buckling part is provided with a fixed buckle, and the fixed buckle is used for cooperating with the pot body to lock the pot cover assembly and the pot body. When the inner cover is installed on the cover body and the locking piece swings towards the center of the cover body, the vertical limiting surface will be stopped by the outer edge of the fixed part, so that the inner cover can also limit the movement of the locking piece to a certain extent, and in this state, the fixed buckle can normally complete the clamping with the pot body, thereby realizing the locking of the pot cover assembly and the pot body. When the inner cover is not installed on the cover body, the locking piece will continue to move towards the center of the cover body in the process of movement, because the vertical limiting surface is not blocked, so that the locking piece will continue to move towards the center of the cover body with a larger amplitude, at this time, the posture of the fixed buckle is abnormal, and the clamping with the pot body cannot be completed, so that the pot cover assembly cannot be locked for cooking. In this way, the installation detection function of the inner cover is realized, when the inner cover is not installed, the pot cover assembly cannot be clamped, so that the cooking which needs to be closed cannot be normally carried out, thereby prompting the user to install the inner cover in time, and ensuring that the cooking is safely and reliably carried out. Only when the inner cover is installed in place, the pot cover assembly can be normally clamped for cooking.

[0023] 4. As a preferred embodiment of the utility model, the pot cover assembly further comprises an elastic piece, and the elastic piece is used for applying an elastic force towards the center of the cover body to the locking piece. The elastic piece is used for applying a force towards the center of the cover body to the locking piece, so that the locking piece can tightly clamp the inner cover under the action of the elastic force of the elastic piece, thereby ensuring the horizontal clamping force of the inner cover and reducing the horizontal shaking of the inner cover. Since the locking piece is rotationally connected to the cover body, the horizontal inward force of the elastic piece can be converted into an upward force, so that the upward abutting force of the locking piece on the inner cover is also increased, the up-down shaking of the inner cover is reduced, and the position of the inner cover is more stable.

[0024] 5. As a preferred embodiment of the utility model, the upper side of the cover body is provided with an upward protruding installation protruding rib, the installation protruding rib surrounds the outer periphery of the installation cavity, the top surface of the installation protruding rib is provided with an assembly plane, and the cover plate is in abutting cooperation with the assembly plane. The installation protruding rib surrounds the installation cavity and is downwardly protruding, which facilitates the cooperation between the cover plate and the installation protruding rib and provides a platform for the installation of the cover plate. Meanwhile, the top surface of the installation protruding rib is provided with an assembly plane, the plane structure makes the contact between the cover plate and the installation protruding rib more close, increases the contact area between them, thereby reducing the gap between them, so that even if no sealing piece is arranged between them, a good sealing property can be formed between the cover plate and the installation protruding rib, and steam leakage above the cover body is avoided. The plane structure makes the installation of the cover plate also more simple and convenient, reduces the installation difficulty of the cover plate, and prevents the cover plate from being deviated.

[0039] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the drawings.

[0040] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to other embodiments that can not be explicitly described or illustrated herein, and the present application is not limited to the embodiments described herein.

[0043] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. In the description of the present application, the description of the terms "embodiment", "example", "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 application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] As shown in Figure 1 , Figure 2 A pot cover assembly, comprising a surface cover 6, a cover body 1 and an inner cover 2 detachably mounted on the cover body 1, the surface cover 6 and the cover body 1 have an electrical appliance mounting space therebetween, the cover body 1 is provided with a through mounting cavity 11, the pot cover assembly further comprises a locking member 3 located at least partially in the mounting cavity 11, the locking member 3 is rotatably connected with the cover body 1 so that the locking member 3 can rotate relative to the cover body 1 to lock the inner cover 2 on the cover body 1; the pot cover assembly further comprises a cover plate 4, the cover plate 4 closes the mounting cavity 11 from above the cover body 1 to isolate the mounting cavity 11 and the electrical appliance mounting space.

[0045] In the utility model, the locking piece 3 is rotatably connected with the cover body 1, so that it can be rotated relative to the cover body 1 to lock or unlock the inner cover 2. Compared with the sliding mode, the rotating mode limits the movement of the locking piece 3 by the connecting shaft 31, so that only the swinging around the connecting shaft 31 can be performed, thereby making the movement track of the locking piece 3 more reliable and stable, and reducing the shaking during the movement of the locking piece 3.

[0046] It can be understood that the power of the sliding mode is provided by the elastic member 5, and the movement of the locking piece is guided and limited only by the sliding cavity formed by the cover plate and the cover body. The size of the cavity is larger than the radial size of the elastic member and the locking piece, so the elastic member will inevitably shake off the axis during the movement of the locking piece, which will further cause the movement of the locking piece to shake. By the rotating mode, the movement of the locking piece 3 is also limited by the movement of the connecting shaft 31, so that the movement of the locking piece 3 can only rotate around the connecting part, thereby greatly reducing the shaking phenomenon.

[0047] At the same time, since the swinging mode of the locking piece 3 is more stable, the space required for movement is smaller, so there is no need to reserve a gap between the cover plate 4 and the cover body 1, so that the cover plate 4 can close the top opening of the mounting cavity 11, improve the contact effect between the cover plate 4 and the cover body 1, thereby improving the sealing performance. The cover plate 4 isolates the mounting cavity 11 and the electrical installation space. When the cover is opened, even if the steam in the pot flows into the mounting cavity 11, it cannot reach the electrical installation space above the cover body 1 due to the blockage of the cover plate 4, which not only ensures the cleanliness of the upper side of the cover body 1 and avoids dirt accumulation, but also prevents the steam from contacting the functional parts and electrical elements on the upper side of the cover body 1, thereby ensuring the service life of the components.

[0048] Specifically, as shown in Figure 1 The locking piece 3 is arranged at the edge of the cover body 1 to clamp and limit the inner cover 2 from the outside of the inner cover 2.

[0049] As a preferred embodiment of the utility model, as shown in Figure 2 , Figure 4 The locking piece 3 includes a connecting part 32 and a limiting part 33 below the connecting part 32. The connecting part 32 is rotatably connected with the cover body 1. The limiting part 33 has a vertical limiting surface 331 and a horizontal limiting surface 332. The edge of the inner cover 2 is provided with a fixed part 21. The vertical limiting surface 331 abuts against the outer edge of the fixed part 21, and the horizontal limiting surface 332 is located below the fixed part 21 to abut against the lower side of the fixed part 21.

[0050] The limiting portion 33 is located below the connecting portion 32, so that the limiting portion 33 can swing around the connecting portion 32 to move towards or away from the center of the cover body 1. When the limiting portion 33 moves towards the center of the cover body 1, it will cooperate with the fixing portion 21 to lock the inner cover 2 on the cover body 1. When the limiting portion 33 moves away from the center of the cover body 1, it will be disengaged from the fixing portion 21 to release the inner cover 2.

[0051] The transverse limiting surface 332 is located below the fixing portion 21 to limit the inner cover 2 from moving downwards, so that the inner cover 2 will not fall off the cover body 1, and the fixing effect of the inner cover 2 is ensured. At the same time, the transverse limiting surface 332 can limit the inner cover 2 from moving in the up-down direction. The vertical limiting surface 331 abuts against the outer edge of the fixing portion 21, so that the inner cover 2 can be limited in the transverse direction, and the inner cover 2 can be kept centered relative to the cover body 1 to avoid the inner cover 2 from moving in the horizontal direction, so that the inner cover 2 is more stable, and the stability of the sealing is ensured.

[0052] Preferably, as shown in Figure 2 , the connecting portion 32 is located at the top of the locking piece 3, so that the locking piece 3 as a whole swings around the top as the center to avoid the locking piece 3 being too high to protrude from the upper surface of the cover body 1, and to avoid interference with the cover plate 4.

[0053] In another embodiment, the connecting portion 32 can also be arranged between the two end portions of the locking piece 3, so that the locking piece 3 as a whole forms a lever structure, and the limiting portion 33 is located below the connecting portion 32. When the limiting portion 33 swings towards the center of the cover body 1, the area of the locking piece 3 above the connecting portion 32 swings away from the center of the cover body 1, i.e. in the opposite direction of the limiting portion 33.

[0054] Further, as shown in Figure 2 , Figure 4 , the locking piece 3 further comprises a buckling portion 36 located below the limiting portion 33. The buckling portion 36 is provided with a fixing buckle for cooperating with the pot body to lock the pot cover assembly with the pot body.

[0055] When the inner cover 2 is installed on the cover body 1, the locking piece 3 swings towards the center of the cover body 1, and the vertical limiting surface 331 is stopped by the outer edge of the fixing portion 21, so that the inner cover 2 can also limit the movement of the locking piece 3. In this state, the fixing buckle can normally be clamped with the pot body, so as to realize the locking of the pot cover assembly and the pot body. When the inner cover 2 is not installed on the cover body 1, the locking piece 3 continues to move towards the center of the cover body 1 during the movement, and the vertical limiting surface 331 is not blocked, so that the locking piece 3 continues to move towards the center of the cover body 1 with a larger amplitude. At this time, the posture of the fixing buckle is abnormal, and the fixing buckle cannot be clamped with the pot body, so that the pot cover assembly cannot be locked for cooking. In this way, the installation detection function of the inner cover 2 is realized. When the inner cover 2 is not installed, the pot cover assembly cannot be clamped, so that the cooking that needs to be closed cannot be normally carried out, so as to prompt the user to install the inner cover 2 in time, and ensure that the cooking is safely and reliably carried out. Only when the inner cover 2 is installed in place, the pot cover assembly can be normally clamped for cooking.

[0056] Specifically, as shown in Figure 2 , the fixing buckle is arranged at the lower end of the locking piece 3, and includes a vertical extension section 361 and a transverse clamping section 362. When the inner cover 2 is installed on the cover body 1, the limiting portion 33 abuts against the outer edge of the fixing portion 21, so that the vertical extension section 361 is in a vertical state, and the transverse clamping section 362 is in a horizontal state, so as to be clamped with the pot body. When the inner cover 2 is not installed on the cover body 1, the locking piece 3 swings to a position closer to the center of the cover body 1, so that the vertical extension section 361 is inclined, and the transverse clamping section 362 is also inclined. At this time, the fixing buckle cannot be clamped with the pot body.

[0057] Preferably, as shown in Figure 2 , Figure 4 , the locking piece 3 includes a limiting portion 33, the limiting portion 33 has a limiting protrusion 34 protruding towards the center of the cover body 1, the edge of the inner cover 2 is provided with a fixing portion 21, the limiting protrusion 34 is located below the fixing portion 21 to limit the fixing portion 21, and the locking piece 3 further includes a holding portion 35 below the limiting portion 33, and the outer surface of the holding portion 35 has a contact arc surface 351.

[0058] As shown in Figure 2 , the limiting protrusion 34 is located below the fixing portion 21 to form an upward support for the fixing portion 21, so as to avoid the inner cover 2 from falling off the cover body 1. The holding portion 35 facilitates the user to operate the locking piece 3. The user can drive the locking piece 3 to rotate through the holding portion 35, so as to make the limiting portion 33 loose from the fixing portion 21. At the same time, the holding portion 35 is far away from the connecting position of the locking piece 3, so that the force arm is long, and the user operates more labor-saving.

[0059] Specifically, the contact arc surface 351 is arranged on the side of the holding portion 35 facing the center of the cover body 1. On one hand, when the user pushes the locking piece 3 outward by contacting the contact arc surface 351, a better gripping feeling can be obtained, and the hands are prevented from slipping on the holding portion 35. On the other hand, the contact arc surface 351 extends to the lower surface of the limiting protrusion 34, and can guide the installation of the inner cover 2. When the inner cover 2 is placed on the lower side of the cover body 1 and is pushed toward the center of the cover body 1, the fixed portion 21 at the edge of the inner cover 2 contacts the contact arc surface 351 and slides upward under the guidance of the contact arc surface 351. The upward force of the inner cover 2 generates a horizontal force away from the center of the cover body 1 through the contact arc surface 351, so as to drive the locking piece 3 to rotate outward, and the limiting protrusion 34 is away from the fixed portion 21. When the fixed portion 21 passes the limiting protrusion 34, the limiting protrusion 34 is reset to limit the fixed portion 21.

[0060] In this way, the contact arc surface 351 realizes the integration of improving the user's operation feeling and guiding the installation of the inner cover 2, and is multi-purpose, so that the contact arc surface 351 is multi-purpose, and the structure of the locking piece 3 is simplified.

[0061] In a preferred embodiment, as shown in Figure 2 , Figure 3 The pot cover assembly further comprises a resilient member 5, which is used to apply a spring force to the locking piece 3 toward the center of the cover body 1.

[0062] The resilient member 5 is used to apply a force to the locking piece 3 toward the center of the cover body 1, so that the locking piece 3 can tightly clamp the inner cover 2 under the action of the spring force of the resilient member 5. The horizontal clamping force of the locking piece 3 on the inner cover 2 is ensured, and the horizontal shaking of the inner cover 2 is reduced. Since the locking piece 3 is rotationally connected to the cover body 1, the locking piece 3 is limited by the rotating shaft 31, and the horizontal inward force of the resilient member 5 can be converted into an upward force, so that the upward abutting force of the locking piece 3 on the inner cover 2 is also increased, the up-down shaking of the inner cover 2 is reduced, and the position of the inner cover 2 is more stable.

[0063] As shown in Figure 2 , the top of the locking piece 3 is rotationally connected to the cover body 1, and the resilient member 5 is located on the outer side (the side away from the center of the cover body 1) of the locking piece 3 to apply a spring force to the limiting portion 33 toward the center of the cover body 1. In other embodiments, the locking piece 3 is rotationally connected to the cover body 1 between the two end portions, so that the locking piece 3 forms a lever structure as a whole, and the limiting portion 33 is located below the connection position. At this time, the resilient member 5 can be arranged on the outer side below the connection position to directly apply a spring force to the limiting portion 33 toward the center of the cover body 1. Alternatively, the resilient member 5 can be arranged on the inner side above the connection position to apply an outward pushing force to the region of the locking piece 3 above the connection position, so that the limiting portion 33 moves toward the center of the cover body 1.

[0064] Preferably, the resilient member 5 is a spring to save costs. Further, as shown inFigure 2 As shown in the figure, the inner wall of the locking piece 3 and / or the mounting cavity 11 is provided with a guide column 37, and the elastic piece 5 is sleeved on the outer periphery of the guide column 37. The guide column 37 can limit the deformation direction of the elastic piece 5, so that it can only deform along its own axis, thereby ensuring that the pushing force is always along the radial direction of the pot cover assembly.

[0065] Preferably, as shown in the figure, Figure 2 As shown in the figure, the inner wall of the locking piece 3 and the mounting cavity 11 is provided with a guide column 37, and the two ends of the elastic piece 5 are sleeved on the outside of the guide column 37. Of course, the guide column 37 can also be provided on any one of the two, which is not limited here.

[0066] Further, as shown in the figure, Figure 2 As shown in the figure, the locking piece 3 is provided with a guide protrusion 38 which surrounds the outer periphery of the guide column 37, so that a limiting space for accommodating the elastic piece 5 is formed between the guide protrusion 38 and the guide column 37.

[0067] After the elastic piece 5 is sleeved on the guide column 37, the outside is limited by the guide protrusion 38, and the inside is limited by the guide column 37. The simultaneous limitation of the inside and outside makes the elastic piece 5 maintain a good posture when it is compressed and stretched, thereby ensuring that the direction and size of the elastic force exerted by the elastic piece 5 on the locking piece 3 are more stable, and the locking piece 3 limits the inner cover 2 more stably and reliably.

[0068] As a preferred embodiment, as shown in the figure, Figure 2 , Figure 3 , Figure 6 As shown in the figure, the upper side of the cover body 1 is provided with a mounting protrusion 12 which protrudes upward, and the mounting protrusion 12 surrounds the outer periphery of the mounting cavity 11. The top surface of the mounting protrusion 12 is provided with an assembly plane, and the cover plate 4 is in abutting cooperation with the assembly plane.

[0069] The mounting protrusion 12 surrounds the mounting cavity 11 and is provided downwardly protruding, which facilitates the cooperation between the mounting protrusion 12 and the cover plate 4, and provides a platform for the installation of the cover plate 4. At the same time, the top surface of the mounting protrusion 12 is provided with an assembly plane, and the plane structure makes the contact between the cover plate 4 and the mounting protrusion 12 more closely, increases the contact area between them, thereby reducing the gap between them. Even if no sealing piece 23 is arranged between the cover plate 4 and the mounting protrusion 12, a better sealing can be formed between them to avoid steam leakage above the cover body 1. The plane structure makes the installation of the cover plate 4 more simple and convenient, reduces the installation difficulty of the cover plate 4, and prevents the cover plate 4 from being deviated.
