[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0032] To facilitate understanding of the training chopsticks provided in this application embodiment, their application scenario is first explained. The training chopsticks provided in this application embodiment are designed to help children practice using chopsticks. However, current training chopsticks have relatively complex structures and are not very convenient to use. Therefore, this application embodiment provides a training chopstick with a simple structure that is convenient for children to practice using. The training chopsticks provided in this application embodiment are described in detail below with reference to specific drawings and embodiments.

[0033] refer to Figure 1 As shown, Figure 1 A schematic diagram of the structure of the training chopsticks provided in this embodiment is shown. The main structure of the training chopsticks provided in this embodiment includes a linkage part 10 and two chopstick bodies, which are named the first chopstick body 20 and the second chopstick body 30 for ease of description. In specific connection, the first chopstick body 20 is fixedly connected to the linkage part 10, while the second chopstick body 30 is rotatably connected to the linkage part 10. Furthermore, the ends of the first chopstick body 20 and the second chopstick body 30 away from the linkage part 10 are flush, serving as gripping ends for holding food. When using the chopsticks, children can move the second chopstick body 30 closer to or further away from the first chopstick body 20 to pick up or put down food.

[0034] Specifically, the surface of the first chopstick 20 that contacts the food is wavy and / or the surface of the first chopstick 20 that contacts the food is wavy. This way, when children use it, the wavy surface can increase the friction between the food and the gripping end, thereby achieving a non-slip effect, and the food is less likely to fall when children pick it up.

[0035] Continue to refer to Figure 1 and Figure 2 The linkage 10 may include a main frame 11 and an elastic structural member 12. The main frame 11 serves as the structural member connecting the linkage 10 to the first chopstick body 20 and the second chopstick body 30, while the elastic structural member 12 serves as a filler fixed within the main frame 11. In a specific configuration, the hardness of the main frame 11 is greater than the hardness of the elastic structural member 12. For example, the main frame 11 is made of PPSU (Polyphenylene sulfone resins), while the elastic structural member 12 is made of silicone.

[0036] The elastic structural component 12 is also equipped with a thumb positioning ring 40, which allows a child to insert their thumb into during use to position the thumb. Simultaneously, the main frame 11 can be pressed against the child's thumb to provide support for the entire training chopstick.

[0037] When the first chopstick body 20 and the second chopstick body 30 are connected to the linkage part 10, the first chopstick body 20 is fixedly connected to the main frame 11, and the second chopstick body 30 is rotatably connected to the main frame 11, thus forming a structure in which one chopstick body is fixed and the other chopstick body is movable. The axis around which the second chopstick body 30 rotates is perpendicular to the arrangement direction of the first chopstick body 20 and the second chopstick body 30, and also perpendicular to the length direction of the second chopstick body 30. When children use the training chopsticks, they can move the second chopstick body 30 closer to or further away from the first chopstick body 20 by rotating it with their fingers.

[0038] In one alternative solution, when the first chopstick body 20 is fixedly connected to the main frame 11 of the linkage part 10, the first chopstick body 20 and the main frame 11 of the linkage part 10 are an integral structure. Alternatively, the first chopstick body 20 and the main frame 11 are separate structures, and the first chopstick body 20 and the main frame 11 are fixedly connected by a connector (such as a threaded connector), or the first chopstick body 20 and the main frame 11 are fixed by adhesive bonding, etc.

[0039] When the training chopsticks are in use, the main frame 11 presses against the child's thumb and forefinger, and the center of gravity of the linkage part 10 is close to the thumb and forefinger, so that the training chopsticks are more stable when the child uses them, reducing the top-heavy nature of the training chopsticks and improving the effectiveness of the child's use.

[0040] As can be seen from the above description, the training chopsticks provided in this embodiment only position the child's thumb using the thumb positioning ring 40, without restricting the other fingers. This makes them convenient for children to use and more in line with the normal way of using chopsticks, thus improving the training effect. In addition, the main frame 11 can rest against the child's thumb and forefinger to increase the stability of the training chopsticks. The entire training chopsticks have a simple structure, are easy for children to use, and are convenient for children to hold.

[0041] When the main frame 11 and the elastic structural member 12 are fixedly connected, it should be understood that when the elastic structural member 12 is filled and fixed inside the main frame 11, the elastic structural member 12 and the main frame 11 are independent structural members, and the elastic structural member 12 can be detached from the main frame 11. For example, the elastic structural member 12 can be fixedly connected to the main frame 11 by a snap-fit ​​connection. In one feasible embodiment, the elastic structural member 12 and the main frame 11 are connected by a snap-fit ​​connection. In this method, the elastic structural member 12 and the main frame 11 are separable, meaning the elastic member 12 can be detached from the main frame 11, facilitating the cleaning of the training chopsticks and reducing the amount of dirt hidden in the gap formed at the connection point between the elastic structural member 12 and the main frame 11.

[0042] In a specific example, the inner wall of the main frame 11 is provided with a limiting protrusion 115, and the elastic structural member 12 is provided with a limiting groove 121 that engages with the limiting protrusion 115. The elastic structural member 12 is fixed to the main frame 11 through the cooperation of the limiting protrusion 115 and the limiting groove 121. In a specific configuration, the limiting protrusion 115 is arranged around the inner wall of the main frame 11 to form a raised structure, while the limiting groove 121 is arranged around the side wall of the elastic structural member 12 to form an annular groove. During assembly, the limiting groove 121 is fitted onto the limiting protrusion 115, which improves the connection strength between the elastic structural member 12 and the main frame 11. In an implementable solution, the limiting protrusion 115 is an arc-shaped structure, which facilitates the assembly of the elastic structural member 12 onto the main frame 11.

[0043] In its specific design, the main frame 11 is a ring-shaped structure, such as... Figure 2 As shown, the main frame 11 is a flat structure that forms a "q"-shaped border, and a "q"-shaped hollow is also formed inside it.

[0044] Different methods can be used to achieve the rotatable connection between the second chopstick body 30 and the main frame 11. Examples are provided below. Figure 2 and Figure 3The inner wall of the main frame 11 is provided with a protruding structure 112, and a receiving groove 114 with an opening exposed on the outer wall of the main frame 11 is provided within the protruding structure 112. That is, when assembling the second chopstick 30, a protruding structure 112 can be formed on the inner wall of the main frame 11 structure, and a groove can be cut in the main frame 11 structure to form the receiving groove 114. The receiving groove 114 extends into the protruding structure 112, so that the main frame 11 has sufficient space to accommodate the end of the second chopstick 30 connected to the main frame 11. The end of the second chopstick 30 is located in the receiving groove 114 and is rotatably connected to the main frame 11, thereby realizing the rotatable connection between the second chopstick 30 and the main frame 11. It should be understood that when the second chopstick 30 is inserted into the receiving groove 114, the size of the receiving groove 114 can ensure the rotation range of the second chopstick 30 relative to the main frame 11. For example, the receiving groove 114 can be a rectangular groove or a fan-shaped groove.

[0045] It should be understood that when a protruding structure 112 is provided on the inner sidewall of the main frame 11, a groove is provided on the elastic structural member 12 to avoid the protruding structure 112. At the same time, the stability of the elastic structural member 12 and the main frame 11 can be enhanced by the cooperation between the protruding structure 112 and the groove.

[0046] In one example, the second chopstick body 30 is rotatably connected to the main frame 11 via a pivot 50. For instance, the second chopstick body 30 is fixedly connected to the pivot 50, and the pivot 50 is rotatably connected to the main frame 11; or the second chopstick body 30 is rotatably connected to the pivot 50, while the pivot 50 is fixedly connected to the main frame 11. Regardless of which method is used, the effect of the second chopstick body 30 rotating relative to the main frame 11 can be achieved.

[0047] In one of the alternative solutions, such as Figure 3 As shown in the embodiment of this application, the training chopsticks also include an elastic element 60, which is used to drive the second chopstick body 30 away from the first chopstick body 20. This elastic element 60 allows the second chopstick body 30 to be driven away from the first chopstick body 20, making it easier for children to use. Furthermore, when the training chopsticks are not in use, the elastic element 60 can cooperate with the side wall of the receiving groove 114 to keep the second chopstick body 30 stable, making it easier for children to pick up the training chopsticks.

[0048] For example, when the second chopstick body 30 is rotatably connected to the main frame 11 via the pivot 50, the elastic element 60 can be a torsion spring. The torsion spring is fitted onto the pivot 50, with one end abutting the second chopstick body 30 and the other end abutting the main frame 11. During use, when the second chopstick body 30 approaches the first chopstick body 20, the torsion spring undergoes elastic deformation.

[0049] Of course, in addition to the torsion spring in the example above, other materials can be used for the elastic element 60. For example, the elastic element 60 can be a rubber spring or a compression spring. When a rubber spring is used, one end of the rubber spring presses against the second chopstick body 30, and the other end presses against the side wall of the receiving groove 114.

[0050] In an optional embodiment, the training chopsticks provided in this application also include a sealing layer, which is an elastic layer. The sealing layer blocks the opening of the receiving groove 114, and the second chopstick body 30 passes through the sealing layer. When this structure is adopted, the opening of the receiving groove 114 can be blocked by the sealing layer, reducing the amount of dirt entering the receiving groove 114.

[0051] In an alternative embodiment, the sealing layer may be an elastic sealing layer, which can act as an elastic element 60 to provide the force for the second chopstick 30 to move away from the first chopstick 20.

[0052] It should be understood that, in addition to the connection method between the second chopstick body 30 and the main frame 11 as described in the example above, other connection methods can also be used. For example, the second chopstick body 30 includes a first rod and a second rod connected to the first rod, wherein the second rod is an elastic rod and is fixedly connected to the main frame 11. When the second chopstick body 30 rotates relative to the main frame 11, this can be achieved through the bending deformation of the second rod of the second chopstick body 30. Using this structure can reduce the gaps formed during assembly between components. In one example, the second rod can be fixedly connected to the main frame 11 by bonding or interference fit. For example, when the second rod is interference-fitted with the main frame 11, a receiving hole is provided on the main frame 11, and part of the second rod is inserted into the receiving hole and interference-fitted with the main frame 11.

[0053] When the elastic structural member 12 is filled into the main frame 11, the elastic structural member 12 covers the hollow area of ​​the main frame 11, so that the elastic structure and the main frame 11 form a solid structure.

[0054] The elastic structural member 12 also serves as a connection structure to the thumb positioning ring 40. For example, the thumb positioning ring 40 is fixed to the elastic structural member 12. In specific fixing methods, different methods can be used, such as adhesive bonding or connection via a connector. When using the above structure, the connection between the elastic structural member 12 and the thumb positioning ring 40 allows the thumb positioning ring 40 to undergo some angular displacement due to the deformation of the elastic structural member 12, improving the comfort of children during use.

[0055] In one feasible embodiment, the thumb positioning ring 40 is also made of an elastic material, which can improve the user experience for children. For example, the thumb positioning ring 40 is integrally formed with the elastic structure 12. In this case, both the elastic structure 12 and the thumb positioning hole 40 are made of silicone. The thumb positioning ring 40 deforms together with the elastic structure 12, providing a greater range of motion and improving the comfort of children during use.

[0056] The linkage 10 provided in this embodiment serves as a connector to support the first chopstick body 20 and the second chopstick body 30. Furthermore, when the second chopstick body 30 is installed, its length is greater than that of the first chopstick body 20. Since the clamping ends of the first chopstick body 20 and the second chopstick body 30 are flush, there is a height difference between the ends of the first chopstick body 20 and the second chopstick body 30 near the linkage 10. Therefore, when the two chopstick bodies are connected to the linkage 10, the connection position between the first chopstick body 20 and the linkage 10 is offset from the connection position between the second chopstick body 30 and the linkage 10 along the length direction of the linkage 10. Specifically, the two chopstick bodies are connected to the main frame 11 of the linkage 10.

[0057] When adopting this structure, the structure of the first chopstick body 20, which is fixedly connected to the main frame 11, is made relatively short. For example, in the length direction of the linkage part 10, the part where the linkage part 10 and the first chopstick body 20 are connected is lower than the height of the part where the linkage part 10 and the second chopstick body 30 are connected, so that the center of gravity of the linkage part 10 is closer to the child's thumb and forefinger, improving the stability of the training chopsticks during use.

[0058] Furthermore, when the second chopstick 30 rotates to a position close to the first chopstick 20, at least part of the portion of the second chopstick 30 extending beyond the first chopstick 20 is exposed outside the main frame 11 along the arrangement direction of the first chopstick 20 and the second chopstick 30. That is, when the second chopstick 30 is set, the portion extending beyond the first chopstick 20, except for the end connected to the main frame 11, is exposed outside the linkage part 10. Using this structure minimizes the overlapping and intersecting areas of components, thereby reducing gaps formed on the training chopsticks, reducing cleaning dead zones, facilitating cleaning of the training chopsticks, and improving their cleanliness.

[0059] Continue to refer to Figure 1 As shown, the linkage part 10 provided in this embodiment can adopt a flat structure, with its length direction along the length direction of the first chopstick body 20 and its width direction along the arrangement direction of the first chopstick body 20 and the second chopstick body 30. When the thumb positioning ring 40 is provided, the thumb positioning ring 40 is located on a flat surface of the linkage part 10, and its position matches the position of the first chopstick body 20, so as to facilitate children's grip.

[0060] The main frame 11 of the linkage 10 has a sidewall for abutting against the tiger's mouth (the opening between the thumb and forefinger). This sidewall is a narrow sidewall (its width is equal to the thickness of the main frame 11) located near the tiger's mouth. For ease of description, this sidewall is referred to as the first sidewall. The first sidewall is a straight sidewall, and its length direction is parallel to the length direction of the first chopstick body 20 or forms a small angle with the length direction of the first chopstick body 20. As an optional solution, the first sidewall can also be an arc-shaped sidewall. The curvature of this arc-shaped sidewall can match the curvature of the tiger's mouth, which can also improve the stability of the linkage 10 when the training chopsticks are in use.

[0061] In one alternative design, the end of the main frame 11 furthest from the first chopstick body 20 is an arc-shaped end, thereby reducing the sharp edges and corners of the training chopsticks and improving their safety during use.

[0062] When the main frame 11 and the second chopstick 30 are engaged, a notch 111 is provided at the end of the main frame 11 near the first chopstick 20. The portion of the second chopstick 30 extending beyond the first chopstick 20 is located in the notch 111, and the end of the second chopstick 30 near the main frame 11 is inserted into the notch 111 and rotatably connected to the main frame 11. Figure 1 As shown, the overall shape of the main frame 11 can be considered as a flat, elongated structure. A notch 111 is opened at the end of the main frame 11 near the first chopstick 20, thus forming a structure similar to the letter "q". When using this structure, when the second chopstick 30 is connected to the main frame 11, the portion of the main frame 11 that overlaps with the second chopstick 30 along its length directly avoids the second chopstick 30. During movement, the second chopstick 30 is mostly located outside the main frame 11, and it does not hide inside the main frame 11 when rotating, thereby reducing gaps required for the movement and coordination of the various parts of the training chopsticks, and facilitating the cleaning of the training chopsticks.

[0063] In an optional embodiment, a limiting groove 113 is provided on the side wall of the notch 111. This limiting groove 113 can be used to avoid the second chopstick 30 when it rotates to a set position. For example, the side wall of the notch 111 is a side wall opposite to the first side wall. For ease of description, this side wall is named the second side wall. The length direction of the second side wall is along the length direction of the first chopstick 20 or at a certain angle. When the second chopstick 30 rotates closer to the first chopstick 20, the second chopstick 30 also approaches the second side wall. To avoid interference between the second side wall and the second chopstick 30, a limiting groove 113 is provided on the second side wall. In a specific configuration, the cross-section of the limiting groove 113 matches the shape of the cross-section of the second chopstick 30. For example, the cross-section of the limiting groove 113 can be arc-shaped. Furthermore, the depth of the limiting groove 113 is less than the width of the second chopstick 30, that is, the limiting groove 113 is shallow, which facilitates cleaning during washing. The structure of the limiting groove 113 allows the second chopstick body 30 to be at least partially located within the limiting groove 113 when using chopsticks to pick up food. At this time, the limiting groove 113 acts as a track, preventing the clamping end of the first chopstick body 20 and the clamping end (i.e. chopstick tip) of the second chopstick body 30 from being misaligned, thus improving the user experience.
