Description

Technical Field

[0001] The present application relates to the technical field of magnetic cups, and in particular to a magic ball switch for a magnetic cup. Background Art

[0002] The magnetic cup is a tea brewing cup that controls the separation of tea and water through a magic ball switch. The magic ball switch is usually composed of an upper hemisphere shell and a lower hemisphere shell assembled by a snap fit to form a rotatable sphere in the magnetic cup. The user rotates the magic ball switch to achieve the control operation of separating tea and water.

[0003] The snap structures in the magic ball switch are usually provided in at least three groups, and these snap structures are evenly spaced along the connection between the upper hemispherical shell and the lower hemispherical shell to improve the stability of the magic ball switch when the upper hemispherical shell and the lower hemispherical shell are assembled together.

[0004] However, in the process of assembling the upper hemispherical shell and the lower hemispherical shell together through the snap-fit ​​structure, the upper hemispherical shell or the lower hemispherical shell needs to undergo elastic deformation in order to complete the snap-fit ​​process smoothly. However, when there are at least three groups of snap-fit ​​structures, it is difficult for the spherical shell to undergo elastic deformation during the assembly of the magic ball switch, causing part of the snap-fit ​​structure to break, and the upper hemispherical shell and the lower hemispherical shell are prone to cracking, thereby reducing the stability of the connection between the upper hemispherical shell and the lower hemispherical shell. This problem urgently needs to be improved. Utility Model Content

[0005] In order to improve the stability of the magic ball switch assembly, the present application provides a magic ball switch with a magnetic cup.

[0006] The present application provides a magic ball switch for a magnetic cup, which adopts the following technical solution:

[0007] A magic ball switch for a magnetic cup includes a first hemispherical shell and a second hemispherical shell fixedly connected by buckling. The inner sidewalls of the first hemispherical shell and the second hemispherical shell are symmetrically provided with two snap-fit ​​structures. When the first hemispherical shell and the second hemispherical shell are buckled together, the sidewalls can undergo elastic deformation. The inner walls of the first hemispherical shell and the second hemispherical shell between the two snap-fit ​​structures are provided with a limiting structure for preventing the first hemispherical shell and the second hemispherical shell from rotating relative to each other.

[0008] By adopting the above technical solution, the first hemispherical shell and the second hemispherical shell are connected by two symmetrically arranged snap structures, and then the limiting structure limits the first hemispherical shell and the second hemispherical shell connected together, making it difficult for the first hemispherical shell and the second hemispherical shell connected together to rotate, thereby realizing the fixed assembly of the first hemispherical shell and the second hemispherical shell to form the magic ball switch of the magnetic cup. During the buckling process of the first hemispherical shell and the second hemispherical shell, the side walls thereof can undergo elastic deformation to facilitate the buckling action of the two snap structures, and the snap structures will not break, which is beneficial to improving the stability of the magic ball switch assembly.

[0009] Preferably, the main body of elastic deformation is the first hemispherical shell, and the elastic deformation of the first hemispherical shell includes inward contraction deformation and outward expansion deformation. The direction of the inward contraction deformation is the line between the center points of the two limiting structures and shrinks toward the inner center of the first hemispherical shell. The direction of the outward expansion deformation is the line between the center points of the two snap structures and expands toward the outside of the first hemispherical shell.

[0010] By adopting the above technical solution, the first hemispherical shell undergoes elastic deformation and is adaptively adjusted to the snapping process of the snap structure, so that the snap structure is difficult to break when the snap action is performed. During the elastic deformation of the first hemispherical shell, the first hemispherical shell expands outward at the position of the snap structure, and contracts inward at the position of the first hemispherical shell at the limiting structure, thereby facilitating the elastic deformation of the first hemispherical shell.

[0011] Preferably, the material hardness of the first hemispherical shell is less than the material hardness of the second hemispherical shell.

[0012] By adopting the above technical solution, this arrangement ensures that during the buckling process of the first hemispherical shell and the second hemispherical shell, the first hemispherical shell undergoes elastic deformation while the second hemispherical shell does not undergo elastic deformation.

[0013] Preferably, the mass of the first hemispherical shell is smaller than the mass of the second hemispherical shell.

[0014] By adopting the above technical solution, this setting ensures that the center of mass of the magic ball switch formed by assembling the first hemispherical shell and the second hemispherical shell is located on one side of the second hemispherical shell, thereby making it convenient for users to control the separation of tea and water through the magic ball switch.

[0015] Preferably, the number of the limiting structures is set to two, the two limiting structures are symmetrically arranged, and each limiting structure is located in the middle position between the two snap structures.

[0016] By adopting the above technical solution, the two limiting structures simultaneously limit the first hemispherical shell and the second hemispherical shell connected together, which is beneficial to improving the limiting effect. Each limiting structure is located in the middle position between the two snap structures, which is beneficial to improving the stability of the magic ball switch assembly.

[0017] Preferably, the snap-fit ​​structure includes a first notch and a second notch respectively arranged on the first hemispherical shell and the second hemispherical shell, the first notch is convex toward the center of the ball, the second notch is concave toward the center of the ball, and the first notch and the second notch are inverted and matched, and the first notch and the second notch are engaged to lock the first hemispherical shell and the second hemispherical shell.

[0018] By adopting the above technical solution, the first notch is convex toward the center of the sphere, the second notch is concave toward the center of the sphere, and the first notch and the second notch are inverted and matched. The first hemispherical shell and the second hemispherical shell can be locked together through the snap-fit ​​cooperation of the first notch and the second notch, making the connection operation of the first hemispherical shell and the second hemispherical shell convenient and quick.

[0019] Preferably, the first notch is configured as a card block, and the upper side wall of the card block is configured as a beveled edge, and the second notch is configured as a card slot, and the lower end of the card slot is configured to cooperate with the card block in a wedge shape.

[0020] By adopting the above technical solution, during the buckling process of the clamping block and the clamping slot, the lower end of the clamping slot and the clamping block are wedge-shaped and cooperate with each other to facilitate the elastic deformation of the first hemispherical shell, thereby improving the convenience when the first hemispherical shell and the second hemispherical shell are assembled together.

[0021] Preferably, the two clamping blocks are located on the first hemispherical shell, and the clamping groove is located on the second hemispherical shell in the form of an annular groove.

[0022] By adopting the above technical solution, when the two clamping blocks are located on the first hemispherical shell, the clamping groove is located on the second hemispherical shell in the form of an annular groove to meet the snap-fitting requirements of the two clamping blocks, thereby reducing the processing difficulty of the second hemispherical shell and reducing the weight of the second hemispherical shell, making the magnetic cup lighter.

[0023] Preferably, the two blocks are respectively arranged on the first hemispherical shell and the second hemispherical shell, and the two slots are correspondingly arranged on the second hemispherical shell and the first hemispherical shell. The block located on the first hemispherical shell corresponds to the slot located on the second hemispherical shell, and the block located on the second hemispherical shell corresponds to the slot located on the first hemispherical shell.

[0024] By adopting the above technical solution, this arrangement is conducive to improving the symmetry when the first hemispherical shell and the second hemispherical shell are connected together, thereby helping to improve the stability of the magic ball switch assembly.

[0025] Preferably, the limiting structure includes a limiting column, which is fixedly connected to the inner wall of the first hemispherical shell or the second hemispherical shell. When the limiting column is fixedly connected to the inner wall of the first hemispherical shell, one end of the limiting column is passed through the opening of the first hemispherical shell, and the second hemispherical shell is correspondingly provided with a limiting groove for the end of the limiting column to be inserted; when the limiting column is fixedly connected to the inner wall of the second hemispherical shell, one end of the limiting column is passed through the opening of the second hemispherical shell, and the limiting groove is correspondingly opened on the first hemispherical shell.

[0026] By adopting the above technical solution, the first hemispherical shell and the second hemispherical shell are connected together by a snap-fit ​​structure. When the limiting post is fixedly connected to the first hemispherical shell, one end of the limiting post is fixed to the first hemispherical shell, and the other end of the limiting post is passed through the opening of the first hemispherical shell and inserted into the limiting groove on the second hemispherical shell, so that the first hemispherical shell and the second hemispherical shell connected together are difficult to rotate relative to each other; when the limiting post is fixedly connected to the second hemispherical shell, one end of the limiting post is fixed to the second hemispherical shell, and the other end of the limiting post is passed through the opening of the second hemispherical shell and inserted into the limiting groove on the first hemispherical shell, so that the first hemispherical shell and the second hemispherical shell connected together are difficult to rotate relative to each other, thereby realizing the fixed connection between the first hemispherical shell and the second hemispherical shell to form a magic ball switch.

[0027] Preferably, when the limit post is inserted into the limit groove, the two opposite side walls of the limit post are tightly fitted with the two opposite side walls of the limit groove, and there is a distance between the side wall of the limit post facing the center of the ball and the limit groove. When the first hemispherical shell undergoes elastic deformation, the limit groove has space for the limit post to move toward the center of the ball.

[0028] By adopting the above technical solution, when the limit post is inserted into the limit groove, the two opposite side walls of the limit post are tightly fitted to the two opposite groove walls of the limit groove, making it difficult for the first hemispherical shell and the second hemispherical shell connected together to rotate. At the same time, the process of the card block being inserted into the card slot causes the first hemispherical shell to undergo elastic deformation, that is, the first hemispherical shell is pulled outward at the position of the card block, and the first hemispherical shell is squeezed inward at the position of the limit post. There is a distance between the side wall of the limit post facing the center of the ball and the limit groove to avoid the inward squeezing activity of the limit post, thereby facilitating the elastic deformation of the first hemispherical shell.

[0029] Preferably, when the limiting column is fixedly connected to the first hemispherical shell, the end of the limiting column located inside the first hemispherical shell extends to the bottom of the first hemispherical shell; when the limiting column is fixedly connected to the second hemispherical shell, the end of the limiting column located inside the second hemispherical shell extends to the bottom of the second hemispherical shell.

[0030] By adopting the above technical solution, when the limiting column is fixedly connected to the first hemispherical shell, this setting is conducive to improving the structural stability of the connection between the limiting column and the first hemispherical shell; when the limiting column is fixedly connected to the second hemispherical shell, this setting is conducive to improving the structural stability of the connection between the limiting column and the second hemispherical shell.

[0031] Preferably, the width of the vertical cross-section of the limiting column gradually increases from top to bottom, and the width of the transverse cross-section of the limiting column gradually decreases toward the center of the sphere.

[0032] By adopting the above technical solution, this arrangement is conducive to further improving the structural stability of the limit column connection.

[0033] Preferably, coaxial rotating shafts are fixedly provided on opposite sides of the opening of the first hemispherical shell, and the second hemispherical shell is correspondingly provided with an axis groove for inserting the rotating shaft, and the end of the rotating shaft away from the center of the sphere extends outward. When the first hemispherical shell and the second hemispherical shell are assembled together, the rotating shaft is evenly distributed on the first hemispherical shell and the second hemispherical shell.

[0034] By adopting the above technical solution, the setting of the two rotating shafts makes it convenient to rotate the magic ball switch assembled by the first hemispherical shell and the second hemispherical shell and connect it to the magnetic cup, so that the user can realize the control operation of separating tea and water by turning the magic ball switch. The even distribution of the rotating shafts on the first hemispherical shell and the second hemispherical shell is conducive to improving the stability of the magic ball switch during rotation.

[0035] Preferably, the rotating shaft is fixedly connected to the limiting column.

[0036] By adopting the above technical solution, this arrangement enables the rotating shaft, the limiting column and the first hemispherical shell to form a triangular positioning, which is beneficial to further improve the structural stability of the magic ball switch.

[0037] Preferably, the blocking block is at a distance from the opening plane of the first hemispherical shell, and a step is provided at the opening of the second hemispherical shell.

[0038] By adopting the above technical solution, this arrangement enables the first hemispherical shell and the second hemispherical shell to fit together more closely, which is beneficial to improving the structural strength of the fixed connection between the first hemispherical shell and the second hemispherical shell.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. By setting two snap structures and two limiting structures, the first hemispherical shell and the second hemispherical shell are connected through the two symmetrically arranged snap structures, and then the limiting structure limits the first hemispherical shell and the second hemispherical shell connected together, so that the first hemispherical shell and the second hemispherical shell connected together are difficult to rotate relative to each other. The two limiting structures simultaneously limit the first hemispherical shell and the second hemispherical shell connected together, which is beneficial to improving the limiting effect, thereby realizing the magic ball switch of the magnetic cup by fixedly assembling the first hemispherical shell and the second hemispherical shell. At the same time, during the buckling process, the side walls of the first hemispherical shell and the second hemispherical shell can undergo elastic deformation to facilitate the buckling action of the two snap structures, and the snap structures will not break, which is beneficial to improving the stability of the magic ball switch assembly.

[0041] 2. By arranging the lower end of the slot and the card block in a wedge shape, it is easy to push the first hemispherical shell to undergo elastic deformation during the buckling process of the card block and the slot, thereby facilitating the assembly of the first hemispherical shell and the second hemispherical shell.

[0042] 3. There is a distance between the side wall of the limiting post facing the center of the ball and the limiting groove. When the limiting post is inserted into the limiting groove, the process of the card block being locked into the card slot causes the first hemispherical shell to undergo elastic deformation, that is, the first hemispherical shell is pulled outward at the position of the card block, and the first hemispherical shell is squeezed inward at the position of the limiting post. There is a distance between the side wall of the limiting post facing the center of the ball and the limiting groove to avoid the inward squeezing activity of the limiting post, thereby facilitating the elastic deformation of the first hemispherical shell.

[0052] The following is combined with Figure 1-7 This application is described in further detail.

[0053] The present application embodiment discloses a magic ball switch of a magnetic cup, referring to Figure 1 and Figure 2 , comprising a first hemispherical shell 1 and a second hemispherical shell 2 fixedly connected by snapping, the first hemispherical shell 1 and the second hemispherical shell 2 having the same diameter, the openings of the first hemispherical shell 1 and the second hemispherical shell 2 being arranged in opposite directions, the inner sidewalls of the first hemispherical shell 1 and the second hemispherical shell 2 being symmetrically provided with two snap-fit ​​structures 3, the first hemispherical shell 1 and the second hemispherical shell 2 being connected by the two snap-fit ​​structures 3, the sidewalls of the first hemispherical shell 1 and the second hemispherical shell 2 being elastically deformed when the first hemispherical shell 1 and the second hemispherical shell 2 are snapped together, so as to facilitate the snap-fitting process of the two snap-fit ​​structures 3, and at the same time, a limiting structure 4 for preventing the first hemispherical shell 1 and the second hemispherical shell 2 from rotating relative to each other is provided on the inner wall of the first hemispherical shell 1 and the second hemispherical shell 2 between the two snap-fit ​​structures 3. When the first hemispherical shell 1 and the second hemispherical shell 2 are connected together by the snap-fit ​​structures 3, the limiting structure 4 limits the first hemispherical shell 1 and the second hemispherical shell 2 to prevent the first hemispherical shell 1 and the second hemispherical shell 2 from rotating relative to each other in the connected state, thereby stably connecting the first hemispherical shell 1 and the second hemispherical shell 2 together.

[0054] It should be noted that the material hardness of the first hemispherical shell 1 is less than that of the second hemispherical shell 2, so that the main body undergoing elastic deformation is the first hemispherical shell 1. The elastic deformation of the first hemispherical shell 1 includes inward contraction and outward expansion. The direction of the inward contraction is the line between the center points of the two limiting structures 4 and shrinks inward toward the inner center of the first hemispherical shell 1. The direction of the outward expansion is the line between the center points of the two snap structures 3 and expands outward from the first hemispherical shell 1. It is worth mentioning that the mass of the first hemispherical shell 1 is less than that of the second hemispherical shell 2, so that the center of gravity of the magic ball switch formed after the first hemispherical shell 1 and the second hemispherical shell 2 are located on one side of the second hemispherical shell 2, thereby facilitating the user to control the tea and water separation through the magic ball switch.

[0055] Reference Figure 2 、 Figure 3 and Figure 4 The snap-fit ​​structure 3 includes a first notch and a second notch respectively provided on the first hemispherical shell 1 and the second hemispherical shell 2. The first notch is convex toward the center of the ball, and the second notch is concave toward the center of the ball. The first notch and the second notch are inverted and matched. When the first hemispherical shell 1 and the second hemispherical shell 2 move toward each other, the first notch and the second notch engage to lock the first hemispherical shell 1 and the second hemispherical shell 2, thereby realizing the connection between the first hemispherical shell 1 and the second hemispherical shell 2.

[0056] Reference Figure 2 、 Figure 3 and Figure 4 The first notch is configured as a clamping block 5, and correspondingly, the second notch is configured as a clamping slot 6. The clamping block 5 is snapped into the clamping slot 6 to achieve a snap connection. It is worth mentioning that the upper side wall of the clamping block 5 is configured as a beveled edge, and the lower end of the clamping slot 6 is configured to cooperate with the clamping block 5 in a wedge shape. During the buckling process of the clamping block 5 and the clamping slot 6, this configuration facilitates the elastic deformation of the first hemispherical shell 1, thereby improving the convenience of assembling the first hemispherical shell 1 and the second hemispherical shell 2. In this embodiment, the two clamping blocks 5 are located on the same cross section of the first hemispherical shell 1, and the clamping groove 6 is located on the second hemispherical shell 2 in the form of an annular groove, so that the two clamping blocks 5 can be simultaneously clamped into the clamping groove 6. In other embodiments, the two clamping blocks 5 are respectively provided on the first hemispherical shell 1 and the second hemispherical shell 2, and the two clamping grooves 6 are respectively provided on the second hemispherical shell 2 and the first hemispherical shell 1. The clamping block 5 located on the first hemispherical shell 1 corresponds to the clamping groove 6 located on the second hemispherical shell 2, and the clamping block 5 located on the second hemispherical shell 2 corresponds to the clamping groove 6 located on the first hemispherical shell 1, so as to achieve a snap-fit ​​connection.

[0057] Reference Figure 4 and Figure 5 The block 5 is some distance away from the opening plane of the first hemispherical shell 1, and a step 11 is correspondingly provided at the opening of the second hemispherical shell 2, so that the first hemispherical shell 1 and the second hemispherical shell 2 can be tightly fitted and assembled together. In this embodiment, since the two blocks 5 are located on the first hemispherical shell 1, the step 11 on the second hemispherical shell 2 is annularly arranged. In other embodiments, the two blocks 5 are respectively arranged on the first hemispherical shell 1 and the second hemispherical shell 2, and the two steps 11 are correspondingly arranged on the second hemispherical shell 2 and the first hemispherical shell 1. As long as the two hemispherical shells are tightly fitted, it will not be elaborated here.

[0058] Reference Figure 6 and Figure 7 The number of the limiting structures 4 is set to two, and the two limiting structures 4 are symmetrically arranged, and each limiting structure 4 is located in the middle position between the two buckle structures 3 to improve the limiting effect. Figure 3and Figure 4 The limiting structure 4 includes a limiting post 7, which is fixedly connected to the inner side wall of the first hemispherical shell 1 or the second hemispherical shell 2. In this embodiment, the limiting post 7 is fixedly connected to the inner side wall of the first hemispherical shell 1, and the limiting post 7 is perpendicular to the open end surface of the first hemispherical shell 1. It is worth mentioning that in order to improve the structural stability of the fixed connection between the limiting post 7 and the first hemispherical shell 1, the end of the limiting post 7 located inside the first hemispherical shell 1 extends downward to the bottom of the first hemispherical shell 1, and the width of the vertical cross-section of the limiting post 7 gradually increases from top to bottom, while the width of the transverse cross-section of the limiting post 7 gradually decreases toward the center of the hemispherical shell.

[0059] Reference Figure 2 、 Figure 3 and Figure 4 , the other end of the limiting post 7 is passed through the opening of the first hemispherical shell 1, and the second hemispherical shell 2 is correspondingly provided with a limiting groove 8 for the end of the limiting post 7 passing through to be inserted. As the first hemispherical shell 1 and the second hemispherical shell 2 are connected together by the two snap structures 3, the end of the limiting post 7 passing through the opening of the first hemispherical shell 1 is inserted into the limiting groove 8, and the two opposite side walls of the limiting post 7 respectively abut against the two opposite side walls of the limiting groove 8, so that the first hemispherical shell 1 and the second hemispherical shell 2 connected together are difficult to rotate. In other embodiments, the limiting post 7 can be fixedly connected to the inner side wall of the second hemispherical shell 2, the limiting post 7 is perpendicular to the open end face of the second hemispherical shell 2, the end of the limiting post 7 located inside the second hemispherical shell 2 extends to the bottom of the second hemispherical shell 2, the other end of the limiting post 7 is passed through the opening of the second hemispherical shell 2, and the limiting groove 8 is correspondingly opened on the first hemispherical shell 1, which will not be described in detail here.

[0060] Reference Figure 6 and Figure 7 The process of the block 5 being clamped into the slot 6 causes the first hemispherical shell 1 to undergo elastic deformation, that is, the first hemispherical shell 1 is pulled outward at the position of the block 5, and the first hemispherical shell 1 is squeezed inward at the position of the limit post 7. At the same time, the limit post 7 is inserted into the limit groove 8, and the two opposite side walls of the limit post 7 are tightly fitted with the two opposite groove walls of the limit groove 8. There is a distance between the side wall of the limit post 7 facing the center of the ball and the limit groove 8. When the first hemispherical shell 1 undergoes elastic deformation, the limit groove 8 has space for the limit post 7 to move toward the center of the ball, so as to avoid the inward squeezing activity of the first hemispherical shell 1 at the position of the limit post 7, thereby facilitating the elastic deformation of the first hemispherical shell 1.

[0061] Reference Figure 3 、 Figure 4 and Figure 6Coaxial rotating shafts 9 are fixedly disposed on opposite sides of the opening of the first hemispherical shell 1. A corresponding shaft slot 10 for the rotating shaft 9 is formed in the second hemispherical shell 2. The ends of the rotating shafts 9, facing away from the center of the ball, extend outward, so that the assembled magic ball switch is rotatably connected to the magnetic cup via the two rotating shafts 9. It should be noted that when the first hemispherical shell 1 and the second hemispherical shell 2 are assembled together, the rotating shafts 9 are evenly distributed on the first hemispherical shell 1 and the second hemispherical shell 2 to improve the stability of the magic ball switch during rotation. Furthermore, the two rotating shafts 9 are respectively fixedly connected to two limiting posts 7, so that the rotating shafts 9, the limiting posts 7, and the first hemispherical shell 1 form a triangular positioning, which helps further improve the structural stability of the magic ball switch.

[0062] The implementation principle of the magic ball switch of a magnetic cup in the embodiment of the present application is as follows: during the assembly process of the magic ball switch, the openings of the first hemispherical shell 1 and the second hemispherical shell 2 are arranged opposite to each other and move in a direction close to each other, the two clamping blocks 5 are synchronously clamped into the clamping groove 6 to realize the connection between the first hemispherical shell 1 and the second hemispherical shell 2, and the two limiting posts 7 are synchronously inserted into the limiting groove 8 to prevent the first hemispherical shell 1 and the second hemispherical shell 2 connected together from rotating relative to each other, thereby realizing the fixed connection between the first hemispherical shell 1 and the second hemispherical shell 2. In the process, the first hemispherical shell 1 undergoes elastic deformation, that is, the first hemispherical shell 1 is pulled outward at the position of the block 5, and the first hemispherical shell 1 is squeezed inward at the position of the limit post 7. The two opposite side walls of the limit post 7 are tightly fitted with the two opposite groove walls of the limit groove 8. The distance between the side wall of the limit post 7 facing the center of the ball and the limit groove 8 avoids the inward squeezing activity of the first hemispherical shell 1 at the position of the limit post 7, thereby facilitating the elastic deformation of the first hemispherical shell 1 and preventing the buckle structure 3 from breaking, which is beneficial to improving the stability of the magic ball switch assembly.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
