AI Technical Summary
The magnetic structure design of existing toy water balloons results in too small a circumferential distance between adjacent magnetic components, increasing production difficulty and cost. At the same time, excessive magnetic force can easily cause water leakage and make it difficult for young children to effectively break the water balloon, affecting their play experience.
The design employs an inner and outer ring ribs. The inner ring ribs contain a first magnetic element, and the outer ring ribs contain a second magnetic element. The magnetic attraction is radial. Combined with the connecting piece made of soft rubber material and the ring structure, it forms a water-tight self-locking function, reducing the number of magnetic elements and the magnetic attraction requirements.
It effectively prevents water leakage, reduces production costs, increases the spacing between magnetic components, improves the success rate of water balloon cracking, and enhances the playing experience.

Technical Field
[0001] This utility model belongs to the technical field of toys, specifically relating to a toy water balloon. Background Technology
[0002] The toy water balloon is designed for players to play in water. Its conventional structure is shown in Chinese patent documents with authorization announcement numbers CN118217643 and CN221981557. It includes a first hemispherical water bladder and a second hemispherical water bladder made of soft rubber material. The edge of the first hemispherical water bladder has a first contact surface, and the edge of the second hemispherical water bladder has a second contact surface. When the toy water balloon is in a closed state, the edges of the first and second hemispherical water bladders are attracted by magnetic force to form a spherical water-carrying cavity. The first contact surface is attached to the second contact surface, and the contact surfaces of the first and second contact surfaces are located in a plane passing through the center of the water balloon. The direction of the magnetic force is tangential to the spherical water-carrying cavity. The playing process is as follows: First, place the toy water balloon into the water to fill the cavity with water. After the water has filled the cavity, use magnetic attraction to close the first and second hemispherical water bladders, achieving a temporary sealing effect. Then, throw the toy water balloon at the opponent. When the toy water balloon hits the opponent, the edges of the first and second hemispherical water bladders are compressed and separated, causing the toy water balloon to crack and the water inside to gush out and splash onto the opponent, achieving the game effect.
[0003] However, the existing operating structure has the following shortcomings: the water seal at the edges of the first and second hemispherical water bladders relies entirely on magnetic force to press the first and second contact surfaces together tangentially from the sphere. Therefore, the circumferential distance between adjacent magnetic components on the edge of the hemispherical water bladder must be short enough. In practice, the arc of the gap between adjacent magnetic components in the circumferential direction generally cannot exceed about 30°, and the magnetic force must be large enough. Otherwise, when the toy water balloon is thrown forcefully, the water bladder wall of the toy water balloon will be subjected to a large pushing force (including the squeezing force required to hold the water balloon). The above pushing force and squeezing force will be converted into water pressure in the inner cavity of the toy water balloon. This water pressure makes it easy for water to leak between adjacent magnetic components, that is, water leakage occurs before hitting the other side.
[0004] The aforementioned shortcomings lead to the following derivative problems: First, because the circumferential spacing between adjacent magnetic components must be short enough, it means that a large number of magnetic components are arranged on the edges of the first and second hemispherical water bladders, increasing costs and production difficulty; Second, after the toy water ball hits the other person's body, due to the large magnetic force, if the speed at which it hits the body is not high enough (because children, especially toddlers, do not have enough strength, so the force and speed of throwing the water ball may not be high enough), the water ball may not be able to break normally, affecting the play experience. Utility Model Content
[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a toy water ball that can both increase the circumferential distance between adjacent magnetic components and prevent water leakage between adjacent magnetic components.
[0006] The objective can be achieved as follows: A toy water balloon includes a first hemispherical water bladder and a second hemispherical water bladder made of soft rubber material. The first hemispherical water bladder has an inner ring rib connected to its edge, and the second hemispherical water bladder has an outer ring rib formed at its edge. The inner ring rib contains several first magnetic elements, and the outer ring rib contains several second magnetic elements. The number of second magnetic elements corresponds to the number of first magnetic elements. When the toy water balloon is in a closed state, the first and second hemispherical water bladders together form a spherical water-carrying cavity. The outer ring rib tightly surrounds the inner ring rib. Each first magnetic element and a corresponding second magnetic element form a magnetic attraction, with the magnetic attraction direction between the first and second magnetic elements being radial to the spherical water-carrying cavity.
[0007] The inner ring rib is also connected to a circular lip, and the second hemispherical water bladder is provided with a circular protruding rib; when the toy water bladder is in the closed state, the circular lip is close to the circular protruding rib.
[0008] The edge of the first hemispherical water bladder is provided with an annular groove. When the toy water bladder is in a closed state, the groove opening faces the second hemispherical water bladder, and the outermost edge of the outer ring rib of the second hemispherical water bladder is embedded in the annular groove.
[0009] A connecting piece made of soft rubber material is provided between the first hemispherical water bladder and the second hemispherical water bladder. The first hemispherical water bladder, the second hemispherical water bladder, and the connecting piece are integrally injection molded.
[0010] The first and second magnetic components are arc-shaped.
[0011] This utility model has the following advantages and effects:
[0012] 1. When the toy water balloon is in a closed state, the outer ring ribs are tightly fitted around the inner ring ribs, thus effectively preventing water leakage. In particular, when the toy water balloon is thrown forcefully, the water pressure inside the toy water balloon increases, but this water pressure causes the inner ring ribs to expand in the centrifugal direction, thereby increasing the fit between the inner and outer ring ribs. This helps to prevent water leakage. From this perspective, the inner and outer ring rib fitting structure of this utility model has a certain degree of water-locking and self-locking function when the first magnetic suction member and the second magnetic suction member are in the state of being attracted together.
[0013] II. As can be seen from the above, the water-tight function of this utility model does not rely entirely on the effect of magnetic force, or rather, the magnetic force only plays an auxiliary role. Therefore, the requirement for the magnitude of the magnetic force is low. Thus, while avoiding water leakage between adjacent magnetic components, the circumferential distance between adjacent magnetic components at the edge of the hemispherical water bladder can be increased, thereby reducing the number of magnetic components (in practice, the arc of the gap between adjacent magnetic components may reach about 60° or even greater), reducing production difficulty and cost. Furthermore, because the required magnetic force is small, the water bladder is more likely to crack normally after hitting the other party's body, thus reducing the probability that the water bladder cannot crack normally and improving the player's experience.

[0024] Figure 11 This is a partially enlarged schematic diagram of Embodiment 2 of this utility model. Detailed Implementation Example 1
[0025] Figure 1 , Figure 2 The toy water balloon shown includes a first hemispherical water bladder 1 and a second hemispherical water bladder 2 made of soft rubber material. A connecting piece 3 made of soft rubber material is also provided between the first hemispherical water bladder 1 and the second hemispherical water bladder 2. The first hemispherical water bladder 1, the second hemispherical water bladder 2 and the connecting piece 3 are integrally injection molded. Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the edge of the first hemispherical water bladder 1 is connected to an annular inner rib 11, and the edge of the second hemispherical water bladder 2 is formed into an annular outer rib 21. The inner rib 11 contains four first magnetic attractors 12, and the outer rib contains four second magnetic attractors 22. The number of second magnetic attractors 22 corresponds to the number of first magnetic attractors 12. The four second magnetic attractors 22 are evenly arranged along the circumference of the outer rib 21, and the four first magnetic attractors 12 are evenly arranged along the circumference of the inner rib 11. Both the first magnetic attractors 12 and the second magnetic attractors 22 are arc-shaped. The edge of the inner rib 11 is also connected to an annular lip 110, and the second hemispherical water bladder 2 is provided with an annular protruding rib 23.
[0026] Figure 9 , Figure 10 As shown, when the toy water balloon is in a closed state, the first hemispherical water bladder 1 and the second hemispherical water bladder 2 enclose each other to form a spherical water-carrying cavity 4. The outer ring ribs 21 tightly surround the outer ring ribs 11. Each first magnetic attractor 12 and a corresponding second magnetic attractor 22 form a magnetic attraction. The magnetic attraction direction of the first magnetic attractor 12 and the second magnetic attractor 22 is radial to the spherical water-carrying cavity 4. The annular lip 110 of the first hemispherical water bladder 1 abuts against the annular convex rib 23 of the second hemispherical water bladder 2, thus adding another layer of water-tight defense.
[0027] In the above embodiment, the circumferential gap between adjacent magnetic components can reach about 65°, and it is not easy to leak water. It can be seen that this utility model can not only increase the circumferential distance between adjacent magnetic components (compared with traditional technology), but also avoid water leakage between adjacent magnetic components. Example 2
[0028] The main difference between Embodiment 2 and Embodiment 1 is that the edge of the first hemispherical water bladder 1 in Embodiment 2 is provided with an annular groove 10. When the toy water bladder is in a closed state, the groove opening of the annular groove 10 faces the second hemispherical water bladder 2, and the outermost edge 210 of the outer ring rib 21 of the second hemispherical water bladder 2 is embedded in the annular groove 10. Figure 11 As shown ( Figure 11 The indicated magnified location is equivalent to Figure 10(The enlarged view of the local area) can add another layer of watertight defense.
[0029] The remaining aspects of the structure of Example 2 are the same as those of Example 1.
