[0001] This utility model relates to the field of toy technology, and in particular to a water ball. Background Technology

[0002] A water balloon is a toy. It's filled with water, and players throw it at their opponents. The player hit gets soaked as the balloon breaks, and the opponent will dodge and retaliate in the same way. It's a safe and fun toy for cooling off in the summer.

[0003] An existing explosive water balloon (i.e., a water balloon) includes a body and a cover. The body has a cavity and an opening communicating with the cavity. Both the body and the cover are made of a flexible, soft material. A connecting member is provided between the body and the cover to ensure that the flexible cover always covers the opening of the body, thus forming a hollow inner cavity. When the body and / or the cover is deformed by pressure, an opening is formed between the body and the cover, and the opening communicates with the inner cavity of the body through the opening.

[0004] The applicant has discovered that the existing technology has at least the following technical problems: When the aforementioned exploding water balloon bursts open, the cover is extremely prone to flipping up. After refilling with water, the user needs to manually flip the cover down so that it covers the opening of the main body before it can be used again. This structure makes the water filling operation cumbersome, inconvenient to use, and results in a poor playing experience. Utility Model Content

[0005] The purpose of this utility model is to provide a water ball to solve the technical problems of cumbersome operation and inconvenience in use when filling water ball structures in the prior art; the various technical effects of the preferred technical solutions provided by this utility model are described in detail below.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] This utility model provides a water ball that can be filled by simply squeezing the inner or outer shell, allowing water to enter through the opening or squeezing port. It is easy to operate.

[0038] The following is combined Figures 1-8 The technical solution provided by this utility model will be described in more detail.

[0039] Example 1:

[0040] See Figures 1-6As shown, the water ball provided by this utility model includes an outer shell 1, an inner shell 2, and a connecting structure. The inner shell 2 and the outer shell 1 are both made of a soft, elastic material. The inner shell 2 is located inside the outer shell 1. The outer shell 1 has an opening 101. The inner shell 2 has an open end 21. The connecting structure (in this embodiment, the connecting structure is a buckle 3) is located at the edge of the opening 101. The connecting structure connects the outer shell 1 and the inner shell 2, and closes the opening 101 from the inside of the inner shell 2, thereby constructing a hollow inner cavity. When the inner shell 2 and / or the outer shell 1 are deformed by force, a compression port 4 is formed between the inner shell 2 and the outer shell 1. The compression port 4 communicates with the hollow inner cavity through the opening 101 and the open end.

[0041] The elastic soft material can be silicone or similar. When the water ball is not subjected to external pressure, the outer wall of the inner shell 2 fits against the outer wall of the outer shell 1, and the inner shell 2 closes the opening 101 on the outer shell 1.

[0042] In existing water balloon technology, the cap is prone to flipping up when the balloon bursts open. After refilling with water, the user needs to manually flip the cap back down so that it covers the opening 101 of the main body before it can be used again. This structure makes the water filling process cumbersome, inconvenient to use, and results in a poor user experience.

[0043] In this embodiment, the water balloon has an opening 101 on the outer shell 1. A connecting structure connects the inner shell 2 and the outer shell 1. The inner shell 2 closes the opening 101 inside the outer shell 1. With this configuration, when the inner shell 2 and the outer shell 1 are compressed, forming a compression port 4 between them, water inside the hollow cavity bursts out from the open end 21, the compression port 4, and the opening 101, achieving water spraying. Furthermore, during the bursting water process, the inner shell 2 and the outer shell 1 do not flip up as in existing technologies. Therefore, when filling with water, the user does not need to flip the cap back up, making operation simple and filling with water more convenient.

[0044] In this embodiment, when the water balloon is not subjected to external pressure, the inner shell 2 seals the opening 101 on the outer shell 1 to prevent internal water leakage. When the water balloon hits a person or an external object, the outer shell 1 or the inner shell 2 is subjected to external force, and the inner shell 2 and the outer shell 1 are squeezed, forming a squeezing port 4 between them. Water bursts out from the squeezing port 4, achieving water spraying. During the bursting process, the inner shell 2 or the outer shell 1 will not flip up. When refilling for use, compared with the existing exploding water balloons that require flipping down the cap, the water balloon of this utility model only needs to squeeze the inner shell 2 or the outer shell 1, and water can enter the water balloon from the opening 101 and the squeezing port 4 to complete the filling process, which is convenient to operate.

[0045] As an optional implementation, see Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, there are multiple openings 101, which are arranged at intervals around the axis of the outer shell 1.

[0046] See Figure 1 , Figure 4 and Figure 6 As shown, there are three openings 101, but there can also be two, four, five, six, etc. The openings 101 are located in the middle of the outer shell 1 to ensure sufficient spraying area. When the inner shell 2 and the outer shell 1 are subjected to external force, such as when water hits a person or an external object, the inner shell 2 and the outer shell 1 deform, and water flows out from the squeezing port 4 and the opening 101 to achieve water bursting. When the water ball is placed in water and the inner shell 2 and the outer shell 1 are squeezed by hand, water enters from the opening 101 and the squeezing port 4. When the hand is released again, the inner shell 2 closes the opening 101, thus filling the water ball with water.

[0047] As an optional implementation, see Figure 1 , Figure 4 and Figure 6 As shown, openings 101 are arranged at intervals around the axis of the outer shell 1, and a partition 102 is formed between adjacent openings 101. The connecting structure fixes the partition 102 to the inner shell 2.

[0048] The connecting structure is located on the partition 102 to connect the outer shell 1 and the inner shell 2. This arrangement can prevent the inner shell 2 and the outer shell 1 from separating and prevent the outer shell 1 from flipping up, ensuring that the inner shell 2 and the outer shell 1 are always connected. Water can burst out or flow in from the opening 101. It is easy to operate and highly entertaining.

[0049] The structure of this embodiment ensures that the water filling action remains quick and convenient even after multiple uses.

[0050] As an optional implementation, see Figure 4 and Figure 5 As shown, one end or both opposite ends of the inner shell 2 are open ends 21. When the water ball is not under pressure, the inner shell 2 is in contact with the inner wall of the outer shell 1. When the inner shell 2 and / or the outer shell 1 are deformed by force, the extrusion port 4 connects the opening 101 and the open end 21.

[0051] See Figure 4 and Figure 5 As shown, the two opposite ends of the inner shell 2 are open ends 21, ensuring that the inner shell 2 has sufficient water outlet area.

[0052] See Figure 2 and Figure 3 As shown, when the water ball is not subjected to external pressure, the inner shell 2 closes the opening 101 on the outer shell 1 to prevent internal water from leaking out; when the water ball hits a person or an external object, the outer shell 1 or the inner shell 2 is subjected to external force, the inner shell 2 and the outer shell 1 are squeezed and a squeezing port 4 is formed between them, and water bursts out from the open end 21 of the inner shell 2, the squeezing port 4 and the opening 101 in sequence, realizing the spraying of water.

[0053] As an optional implementation, the connection structure of this embodiment includes a snap-fit ​​3, a heat-melting part, or an adhesive part.

[0054] The connecting structure can be fixedly connected to the inner shell 2 and the outer shell 1 using riveting, hot melting, or bonding processes. The connection between the connecting structure and the inner shell 2 can be achieved using conventional processes, including riveting, hot melting, bonding, or integral molding.

[0055] As an optional implementation, see Figures 1-8 As shown, the connection structure of this embodiment includes a buckle 3, which is integrally formed on the inner shell 2; the outer shell 1 is provided with a hole 103, and the buckle 3 passes through the hole 103 to connect the inner shell 2 and the outer shell 1.

[0056] The structure of the snap-fit ​​3 enables a stable connection between the outer shell 1 and the inner shell 2, preventing the inner shell 2 from separating from the outer shell 1.

[0057] As an optional implementation, see Figure 3 and Figure 5 As shown, the buckle 3 in this embodiment includes an integrally formed connecting part 31 and a wide diameter part 32, wherein: the connecting part 31 connects the wide diameter part 32 and the inner shell 2, the connecting part 31 passes through the hole 103, the wide diameter part 32 is located outside the outer shell 1, and the outer diameter of the wide diameter part 32 is larger than the hole 103.

[0058] See Figure 3 and Figure 5 As shown, the above-mentioned structure of the buckle 3 facilitates the integral molding of the buckle 3 and the inner shell 2, and enables a stable connection between the outer shell 1 and the inner shell 2, preventing the inner shell 2 from separating from the outer shell 1.

[0059] As an optional implementation, see Figure 3 As shown, a reinforcing rib 5 is provided on the inner wall of the inner shell 2, and the reinforcing rib 5 and the inner shell 2 are integrally formed. The reinforcing rib 5 is a ring-shaped rib.

[0060] To ensure the water bursting effect, the inner shell 2 and the outer shell 1 have relatively small wall thicknesses. In this embodiment, the reinforcing ribs 5 on the inner shell 2 ensure the structural strength of the inner shell 2 after it is filled with water, prevent water leakage when the water ball is not subjected to external force, and ensure the stability when the water ball is thrown.

[0061] Example 2:

[0062] The difference between Example 2 and Example 1 is as follows: See Figure 7 and Figure 8 As shown, in this embodiment, the number of openings 101 on the outer shell 1 is one, and the opening 101 is an annular opening.

[0063] See Figure 7 and Figure 8As shown, when the opening 101 is an annular opening, even if the number of openings 101 is only one, it can still ensure that the water bursts out and ensure the water outlet area.

[0064] See Figure 7 and Figure 8 As shown, the outer shell 1 includes an upper shell 11 and a lower shell 12, the inner shell 2 is located inside the upper shell 11 and the lower shell 12, and an opening 101 is formed between the upper shell 11 and the lower shell 12, and the opening 101 is an annular opening 101; a plurality of connecting structures are connected to the side of the upper shell 11 facing the opening 101, and the remaining connecting structures are connected to the side of the lower shell 12 facing the opening 101.

[0065] In this embodiment, the above-mentioned setting position of the connecting structure can prevent the inner shell 2 or the outer shell 1 from flipping up during the bursting process. When refilling water, compared with the bursting water ball in the prior art that requires flipping down the sealing part, the water ball of this utility model only needs to squeeze the inner shell 2 or the outer shell 1, and water can enter the water ball from the opening 101 and the squeezing port 4 to complete the filling, which is convenient to operate.

[0066] See Figures 1-8 As shown, the water balloon structures in both embodiments can ensure the stability of the connection structure between the inner shell 2 and the outer shell 1. When water bursts, the outer shell 1 and the inner shell 2 will not flip up, so there is no need to flip them down again when filling with water, making filling with water convenient.
