In addition, the middle ring structure is also provided with a wire inlet and a wire outlet for pipelines in the rice cooker to pass through, the pipelines extend into the wire inlet and pass out of the wire outlet, and as the pot cover is closed, the torsional spring needs to be twisted constantly, so that the pipelines are easily interfered with the torsional spring and are pressed by the torsional spring, thereby being damaged.

[0003] To solve the technical problem, the prior art proposes the following solution: a protruding rib is arranged on the mounting seat and the rear cover respectively, the protruding rib is located between the wire inlet and the torsional spring, when the pipeline is displaced towards the torsional spring, the pipeline cannot continue to move due to the stop action of the protruding rib, thereby avoiding the contact between the pipeline and the torsional spring. However, the technical solution has the following problems: due to the need for installation of the rear cover, a gap needs to be reserved between the protruding ribs of the rear cover and the middle ring structure, and the components such as the protruding ribs inevitably have a certain size deviation during the production process and are also easily deformed by external force, so that the gap between the two protruding ribs is increased, and the pipelines often move between the two protruding ribs to the torsional spring during production and maintenance, thereby still having the risk of being pressed by the torsional spring.

[0017] As the above technical scheme is adopted, the application has the following beneficial effects:

[0018] 1. The middle ring structure of the present application opens the pot cover through the torsional force of the torsion spring, and is provided with a rear cover for shielding the torsion spring, improving the appearance of the rice cooker, and the inlet and outlet are arranged staggered with the torsion spring, which can avoid the interference of the torsion spring on the pipeline during the assembly process of the pipeline; the mounting seat and the rear cover are provided with a plurality of limiting mechanisms in position, and the connection between the rear cover and the mounting seat is realized through the limiting mechanism, which improves the fixing strength of the rear cover and the mounting seat, and on this basis, the limiting mechanism is distributed between the inlet and the torsion spring, which can block the movement channel between the pipeline extending from the inlet and the torsion spring, so that the limiting mechanism can limit the pipeline, and when the pipeline is displaced towards the torsion spring due to the rotation of the rear cover or other factors, the limiting mechanism can stop the movement of the pipeline, so that the pipeline cannot move to the torsion spring, reducing the probability of pipeline damage caused by the compression of the torsion spring. In this way, the limiting mechanism has the functions of connecting the rear cover and the mounting seat, and further integrating the pipeline to prevent the pipeline from being squeezed by the torsion spring, which further integrates the functions, helps to optimize the structure design of the middle ring structure; moreover, the pipeline is limited in the preset area by the limiting mechanism, which can effectively reduce the probability of displacement during the pipeline assembly process, providing protection for the installation stability of the pipeline.

[0019] 2. As a preferred embodiment of the present application, the number of torsion springs is set to two and arranged at intervals on both sides of the mounting seat, which can improve the uniformity of the force of the torsion spring on the pot cover, making the opening of the pot cover more smooth and stable; and the inlet and outlet are arranged in the middle of the mounting seat, so that the inlet and outlet are located between the two torsion springs, in this way, only two sets of limiting mechanisms are needed to limit the pipeline, on the one hand, the limiting mechanism is arranged in the middle of the mounting seat and the rear cover, and is arranged in position on both sides of the inlet, which reduces the number of limiting mechanisms under the premise of ensuring the stability of the connection of the rear cover, which helps to optimize the structure design of the mounting seat and the rear cover; on the other hand, the inlet is arranged in the middle of the mounting seat, so that the pipeline located on both sides of the mounting seat can pass through the inlet after experiencing a relatively short layout path, which helps to optimize the arrangement of the pipeline.

[0020] 3. As a preferred embodiment of the present application, the outlet is arranged below the inlet, so that the pipeline passes through the mounting seat along the vertical direction, which can reduce the occupation of the pipeline layout path in the horizontal direction of the middle ring structure, and helps to optimize the structure design of the rice cooker; in addition, a lead beam is arranged below the inlet, which can guide the pipeline to change the extension direction and move towards the outlet, reducing the probability of pipeline displacement.

[0021] 4.

[0022] 5. As a preferred embodiment of the present application, the mounting seat is provided with a first limiting part including a limiting groove, and the rear cover is provided with a second limiting part including a limiting protrusion.

[0023] 6.

The limiting rib increases the stopping area of the pipeline, and enhances the stopping effect of the limiting mechanism on the pipeline.

[0024] Further, a limiting plate is arranged below the limiting rib. Since the outlet is located below the inlet, the extension path of the pipeline passing through the inlet is from top to bottom. Through the arrangement of the limiting plate, the pipeline between the inlet and the outlet can be stopped and limited, and the pipeline extending towards the outlet can be stopped. That is, the arrangement of the limiting plate further increases the stopping area of the pipeline, and further reduces the probability of interference between the pipeline and the torsional spring.

[0046] As shown in Figure 1 , Figure 2 A middle ring structure applied to a rice cooker, the middle ring structure is fixed with a rear cover 1, the middle ring structure is provided with a mounting seat 2 and a torsion spring 3 near the rear cover 1, the mounting seat 2 has a wire inlet 5 and a wire outlet 6 arranged in a staggered manner with the torsion spring 3, the mounting seat 2 is provided with a plurality of limiting mechanisms 4 in a position corresponding to the rear cover 1, the rear cover 1 is connected with the mounting seat 2 through the limiting mechanisms 4, and the plurality of limiting mechanisms 4 are distributed between the wire inlet 5 and the torsion spring 3 to separate the pipeline passing out of the wire inlet 5 from the torsion spring 3.

[0047] The central ring structure of this application uses the torsional force of the torsion spring 3 to open the lid, and a rear cover 1 is provided to cover the torsion spring 3, improving the aesthetic appearance of the rice cooker. The inlet 5 and outlet 6 are both staggered from the torsion spring 3, preventing interference from the torsion spring 3 during the assembly process of threading the pipeline. Multiple limiting mechanisms 4 are provided between the mounting base 2 and the rear cover 1, connecting the rear cover 1 and the mounting base 2 and increasing their fixing strength. Furthermore, the limiting mechanisms 4 are distributed between the inlet 5 and the torsion spring 3, effectively isolating the movement channel between the pipeline extending from the inlet 5 and the torsion spring 3, allowing the limiting mechanisms 4 to limit the movement of the pipeline. When the pipeline is rotated by the rear cover 1 or... When other factors cause the pipeline to shift towards the torsion spring 3, the limiting mechanism 4 can stop the pipeline's movement, preventing it from reaching the torsion spring 3. This reduces the probability of the pipeline being squeezed and damaged by the rotation of the torsion spring 3. In this way, the limiting mechanism 4, in addition to connecting the rear cover 1 and the mounting base 2, further integrates the function of stopping the pipeline to prevent it from being squeezed by the torsion spring 3. This further integration of functions helps to optimize the structural design of the central ring structure. Furthermore, due to the limiting effect of the limiting mechanism 4, the pipeline is confined within a preset area. During pipeline assembly, this effectively reduces the probability of pipeline misalignment during installation, ensuring the stability of the pipeline installation.

[0048] This application does not limit the relative positions of the inlet 5, outlet 6, and torsion spring 3, and they can be implemented in any of the following embodiments:

[0049] Implementation method one: such as Figure 2 As shown, there are two torsion springs 3, which are arranged at intervals on both sides of the mounting base 2. The inlet 5 and outlet 6 are located in the middle of the mounting base 2. There are two limiting mechanisms 4, which are located on both sides of the inlet 5. Setting the number of torsion springs 3 to two and arranging them spaced apart on both sides of the mounting base 2 can improve the uniformity of the force applied by the torsion springs 3 to the pot lid, making the pot lid flip and open more smoothly. Positioning the inlet 5 and outlet 6 in the middle of the mounting base 2, between the two torsion springs 3, requires only two sets of limiting mechanisms 4 to limit the pipeline. Firstly, the limiting mechanisms 4 are positioned in the middle of the mounting base 2 and the rear cover 1, aligned on both sides of the inlet 5, reducing the number of limiting mechanisms 4 while ensuring the stability of the connection to the rear cover 1, thus optimizing the structural design of the mounting base 2 and the rear cover 1. Secondly, the inlet 5 being located in the middle of the mounting base 2 allows pipelines on both sides of the mounting base 2 to pass through the inlet 5 via a relatively short path, helping to optimize the pipeline layout.

[0050] As a preferred embodiment of this implementation, such as Figure 2 , Figure 4As shown, the inlet 5 is located between the two limiting mechanisms 4, and the outlet 6 is located below the inlet 5. A guide beam 7 is provided between the two limiting mechanisms 4, located below the inlet 5. Placing the outlet 6 below the inlet 5 allows the pipeline to pass through the mounting base 2 vertically, reducing the occupation of the horizontal space of the central ring structure by the pipeline path and helping to optimize the structural design of the rice cooker. In addition, the guide beam 7 below the inlet 5 can guide and change the direction of the pipeline, guiding the pipeline exiting from the inlet 5 to change its extension direction and move towards the outlet 6, reducing the probability of pipeline displacement.

[0051] It should be noted that the outlet 6 mentioned in this embodiment is located below the inlet 5, but this does not mean that the outlet 6 must be directly below the inlet 5. A certain degree of misalignment between the two is allowed in the horizontal direction, as long as the vertical height of the outlet 6 is lower than that of the inlet 5. Figure 4 , Figure 5 The diagram illustrates the path of the pipelines, with the dotted lines with arrows representing the pipelines and the arrows indicating the direction of their passage.

[0052] As a preferred example in this embodiment, such as Figure 2 , Figure 5 As shown, the bottom of the mounting base 2 is equipped with a positioning post 21 extending towards the rear cover 1. The rear cover 1 has a mating part 11 that aligns with the positioning post 21. The projection of the cable outlet 6 in the vertical direction is offset from the positioning post 21. The mounting base 2 is provided with the positioning post 21, and the rear cover 1 has a mating part 11 that fits the positioning post 21. Through the mutual cooperation of the positioning post 21 and the mating part 11, the connection between the rear cover 1 and the mounting base 2 is realized. That is, by setting the positioning post 21 and the mating part 11, together with the limiting mechanism 4, the rear cover 1 can be stably installed in the mounting base 2, improving the connection stability between the mounting base 2 and the rear cover 1. On this basis, setting the projection of the cable outlet 6 in the vertical direction to be offset from the positioning post 21 can avoid the interference of the positioning post 21 with the pipeline. Figure 5 The dotted line indicates the pipeline, allowing it to pass smoothly out of the outlet 6. Preferably, the positioning post 21 has an internal thread, and the mating part 11 has a corresponding internal thread with the same direction of rotation. The mating part 11 and the positioning post 21 are connected by screws that pass through the mating part 11 and the positioning post 21 in sequence.

[0053] Implementation method 2: There are two inlet and two outlet ports, located on both sides of the torsion spring, and four limiting mechanisms, located on both sides of the two inlet ports.

[0054] In this embodiment, the torsion spring is located in the middle of the mounting base, and the inlet and outlet are located on both sides of the torsion spring, that is, on the sides of the mounting base. This arrangement provides two paths for the pipeline to pass through, making it easier for the pipeline to reasonably select the inlet and outlet for wiring according to the layout location.

[0055] The number of torsion springs is not limited in the embodiment, and one torsion spring can be arranged between the two incoming line ports 5, or two torsion springs can be arranged at intervals between the two incoming line ports.

[0056] As a preferred embodiment of the present application, as shown in Figure 2 , Figure 3 The limiting mechanism 4 includes a first limiting piece 41 mounted on the mounting seat 2 and a second limiting piece 42 mounted on the rear cover 1. The first limiting piece 41 is provided with a limiting groove 411, and the second limiting piece 42 is provided with a limiting protrusion 421. The first limiting piece 41 and the second limiting piece 42 are connected through the insertion and cooperation of the limiting protrusion 421 and the limiting groove 411. The first limiting piece 41 including the limiting groove 411 is arranged on the mounting seat 2, and the second limiting piece 42 including the limiting protrusion 421 is arranged on the rear cover 1. The first limiting piece 42 and the second limiting piece 42 are connected through the insertion and cooperation of the limiting protrusion 421 and the limiting groove 411, thereby connecting the rear cover 1 and the mounting seat 2. The insertion and cooperation of the limiting protrusion 421 and the limiting groove 411 is relatively simple, which can reduce the assembly difficulty of the rear cover 1 and the mounting seat 2. Moreover, the limiting protrusion 421 and the limiting groove 411 are relatively easy to manufacture, which can help to reduce the processing difficulty of the middle ring structure.

[0057] As a preferred embodiment of the present embodiment, as shown in Figure 3 The first limiting piece 41 includes a back plate 412 close to the incoming line port 5 and a limiting rod 413 away from the outgoing line port 6. The back plate 412 and the limiting rod 413 are arranged at intervals to form the limiting groove 411 therebetween, and the back plate 412 and the limiting rod 413 are connected through a limiting stop rib 414. The back plate 412 and the limiting rod 413 are arranged at intervals to form the limiting groove 411 therebetween, and the back plate 412 and the limiting rod 413 are connected through the limiting stop rib 414. The limiting stop rib 414 increases the stopping area of the pipeline and enhances the stopping effect of the limiting mechanism 4 on the pipeline. Specifically, the limiting stop rib 414 is arranged on the side of the back plate 412 close to the incoming line port 5, thereby preventing the pipeline from extending into the limiting groove 411.

[0058] As a preferred example of the present embodiment, as shown in Figure 3 The limiting plate 8 is connected to the limiting stop rib 414 at one end and extends toward the outgoing line port 6 at the other end. The limiting plate 8 is arranged below the limiting stop rib 414. Since the outgoing line port 6 is located below the incoming line port 5, the extension path of the pipeline passing through the incoming line port 5 is from top to bottom. The limiting plate 8 can stop and limit the pipeline between the incoming line port 5 and the outgoing line port 6, and stop the pipeline extending toward the outgoing line port 6. That is, the limiting plate 8 further increases the stopping area of the pipeline and further reduces the probability of interference between the pipeline and the torsion spring 3.

[0059] Preferably, the extension direction of the limiting plate 8 is the same as the extension direction of the pipeline from the inlet port 5 to the outlet port 6, for example, when the outlet port 6 is directly below the inlet port 5, the limiting plate 8 extends downward in the vertical direction; when the outlet port 6 is obliquely below the inlet port 5, the limiting plate 8 extends obliquely toward the outlet port 6.

[0060] As a preferred embodiment of the present application, as shown in Figure 2 , Figure 3 The torsional spring 3 is sleeved on the torsional spring rod 9, and the mounting seat 2 is provided with a containing groove 22 for containing the torsional spring rod 9 in the extension direction of the torsional spring rod 9. By providing the torsional spring rod 9, the torsional spring 3 is sleeved on the torsional spring rod 9, which provides stable support for the torsion of the torsional spring 3, and the mounting seat 2 is provided with the containing groove 22, which further integrates the function of bearing the torsional spring rod 9 on the basis of the functions of penetrating the pipeline and fixing the rear cover 1, has high degree of functional integration, and optimizes the structural design of the middle ring structure.

[0061] As a preferred example under the present embodiment, as shown in Figure 2 The torsional spring 3 includes a first extension part 31 extending toward the pot cover and a second extension part 32 extending toward the rear cover 1, and the mounting seat 2 is provided with a penetrating groove 23 for the first extension part 31 to penetrate. The first extension part is used to drive the pot cover to overturn, and the second extension part extends toward the rear cover 1 and is shielded by the rear cover 1; the penetrating groove 23 provided on the mounting seat 2 provides a avoiding space for the first extension part 31, and on the other hand, the two inner walls of the penetrating groove 23 can stop the first extension part, limiting its displacement in the direction of the torsional spring rod 9, which helps to improve the installation stability of the torsional spring 3.
