Description

Technical Field

[0001] The utility model relates to the field of water-playing toys, in particular to a toy water ball. Background Art

[0002] There are two types of existing toy water balls, one is a magnetic toy water ball, and the other is a non-magnetic toy water ball. The magnetic toy includes two shells with magnetic parts. The two shells can enclose a water storage cavity, and when the two shells are enclosed, the magnetic parts on the two shells can attract each other to prevent the two shells from being easily separated. Only when the toy water ball is thrown at the player will the two shells be separated by force, causing the player to be wetted by water. Since most of the users of toy water balls are children, they may pull and bite the toy water balls during use. If the magnetic parts of the toy water balls fall out when they are pulled or bitten, there is a risk of them being swallowed by children. In addition, the magnetic toy water balls have multiple magnetic parts, so they are more expensive.

[0003] A non-magnetic toy water ball generally includes two hemispheres, the edges of which are interlocked to define a water storage cavity. The disadvantage of this toy water ball is that the sealing is relatively poor, and the water in the water storage cavity is more likely to overflow. In addition, the connection stability between the two hemispheres of this toy water ball is also relatively poor, and the toy water ball is easy to separate before hitting the player, so the user experience is poor.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0036] The utility model embodiment provides a toy water ball 1000, such as Figure 1-Figure 4 As shown, the toy water ball 1000 includes a flexible shell 100, a flexible cover 200 and an elastic arm 300. The flexible shell 100 defines a water storage chamber 110 and an opening 120 connecting the water storage chamber 110 with the external space of the flexible shell 100; the outer contour of the flexible cover 200 is larger than the contour of the opening 120; the flexible cover 200 is entirely located in the water storage chamber 110 or at least the edge of the flexible cover 200 extends into the water storage chamber 110 and seals the water storage chamber 110. The elastic arm 300 is connected to the flexible shell 100 and extends from the edge of the opening 120 to the center of the opening 120. The elastic arm 300 is connected to the side of the flexible cover 200 facing the external space; the elastic arm 300 is configured to apply an outward force to the flexible cover 200 so that the edge of the flexible cover 200 is close to the inner wall of the water storage chamber 110.

[0037] Specifically, since the flexible shell 100 and the flexible cover 200 are both made of flexible materials, the user can apply force to the toy water ball 1000 to make the toy water ball 1000 produce elastic deformation. At this time, the water storage chamber 110 can be exposed by the opening 120, so as to fill the water storage chamber 110 with water. After filling with water, you only need to stop applying force to the toy water ball 1000, and the toy water ball 1000 will restore the deformation. Since the outer contour of the flexible cover 200 is larger than the contour of the opening 120, and the elastic arm 300 will apply an outward force to the flexible cover 200, the flexible cover 200 will be close to the inner wall of the water storage chamber 110 under the action of the elastic arm 300, so that the water storage chamber 110 can be well sealed to prevent the water in the water storage chamber 110 from leaking out. When the user throws the toy water ball 1000 and it hits the player, the toy water ball 1000 will be impacted by external force and produce elastic deformation. At this time, the water storage chamber 110 can be exposed by the opening 120, and the water in the water storage chamber 110 will overflow from the opening 120 under the action of external force, causing the player hit by the toy water ball 1000 to be wetted by water.

[0038] Of course, it is understandable that throwing the toy water ball at the player is only a reference way to play the water ball game. In addition to throwing it at the player, the toy water ball 1000 can also be simply thrown at the bottom, wall or other places, and this embodiment is not limited here.

[0039] Compared to magnetic water balls, the water balls of this embodiment do not need built-in magnetic parts, so there is no risk of magnetic parts falling out of the water balls 1000 and being swallowed by children when the water balls are pulled or bitten. Since there is no need for built-in magnetic parts, the production cost is also lower than that of magnetic water balls. Therefore, the water balls 1000 of this embodiment have higher safety and lower production cost.

[0040] Compared to non-magnetic toy water balls, the toy water ball 1000 shown in this embodiment has good sealing properties. Specifically, when the flexible cover 200 covers the opening 120 of the flexible shell 100, the elastic arm 300 applies an outward force to the flexible cover 200, so that the flexible cover 200 is pressed against the inner wall of the water storage chamber 110 under the action of the elastic arm 300, so that the water storage chamber 110 can be well sealed to prevent water in the water storage chamber 110 from leaking out.

[0041] refer to Figure 1-Figure 3 In a specific embodiment, the elastic arm 300 and the flexible shell 100 are integrally formed, and the thickness of the elastic arm 300 is greater than the thickness of the flexible shell 100 .

[0042] Specifically, the elastic arm 300 and the flexible shell 100 are integrally formed to not only make the toy water ball 1000 less susceptible to damage, but also effectively reduce the structural complexity of the toy water ball 1000, thereby reducing the production cost of the toy water ball 1000. The thickness of the elastic arm 300 is greater than the thickness of the flexible shell 100, which is conducive to ensuring that the elastic arm 300 provides sufficient force for the flexible cover 200, so that the water storage chamber 110 can be well sealed.

[0043] refer to Figure 1 - Figure 3, in a specific embodiment, the elastic arm 300 is disposed on the outer side of the flexible shell 100, so that the inner wall of the water storage chamber 110 is a spherical or aspherical streamlined curved surface.

[0044] Specifically, if the elastic arm 300 is disposed in the flexible shell 100, the elastic arm 300 will protrude from the wall of the water storage chamber 110, which will affect the sealing performance between the flexible cover 200 and the wall of the water storage chamber 110 to a certain extent. Therefore, in this embodiment, the elastic arm 300 is disposed on the outer side surface of the flexible shell 100 so that the inner wall surface of the water storage chamber 110 is a spherical or aspherical streamlined surface, thereby improving the sealing performance of the flexible cover 200 and the flexible shell 100 when crimped, effectively preventing the water in the water storage chamber 110 from overflowing before the toy water ball 1000 hits the player, and providing an excellent user experience.

[0045] refer to Figure 1-Figure 3 In one embodiment, an elastic ring 400 surrounding the flexible shell 100 is provided near the middle of the flexible shell 100 .

[0046] Specifically, the elastic ring 400 is used to apply a force after the toy water ball 1000 is elastically deformed, so as to cause the toy water ball 1000 to return to a round shape. For example, when the user needs to fill the water storage chamber 110 with water, the toy water ball 1000 can be elastically deformed by applying a force to the toy water ball 1000, and the water storage chamber 110 can be exposed by the opening 120, so as to facilitate the filling of water into the water storage chamber 110. If the force applied when filling water is too large, when the user stops applying the force to the toy water ball 1000, it is difficult for the toy water ball 1000 to return to a round shape smoothly, or the toy water ball 1000 returns to a round shape very slowly. By adding the elastic ring 400, the toy water ball 1000 can be caused to return to a round shape when the user stops applying the force to the toy water ball 1000, and the user experience is excellent.

[0047] refer to Figure 1-Figure 3 In a specific embodiment, the elastic ring 400 is integrally formed with the flexible shell 100 , and the elastic ring 400 protrudes from the inner wall of the water storage cavity 110 or the outer side of the flexible shell 100 .

[0048] Specifically, the elastic ring 400 and the flexible shell 100 are integrally formed to make the toy water ball 1000 less prone to damage, and can also effectively reduce the structural complexity of the toy water ball 1000, thereby reducing the production cost of the toy water ball 1000. In the embodiment where the elastic ring 400 only protrudes from the inner wall of the water storage chamber 110, the elastic ring 400 will not be exposed on the outer surface of the toy water ball 1000, and the visual experience brought by the toy water ball 1000 will be better and more beautiful. In the embodiment where the elastic ring 400 only protrudes from the outer side of the flexible shell 100, the elastic ring 400 will not compress the space of the water storage chamber 110, so that the water storage chamber 110 can accommodate more water. In the embodiment where the elastic ring 400 protrudes from both the inner wall of the water storage chamber 110 and the outer side of the flexible shell 100, the elastic ring 400 will have greater elasticity, which can better promote the toy water ball 1000 to return to a round shape.

[0049] refer to Figure 1-Figure 3 In one embodiment, the elastic arm 300 extends on the flexible shell 100 to connect with the elastic ring 400, so that the structural strength of the elastic arm 300 is higher and can apply more sufficient force to the flexible cover 200, thereby improving the sealing performance when the flexible cover 200 and the flexible shell 100 are crimped.

[0050] refer to Figure 1-Figure 3 In one embodiment, the flexible shell 100 includes an edge portion 130 adjacent to the opening 120 , and the edge portion 130 is folded in a direction away from the water storage chamber 110 .

[0051] Specifically, if the structural strength of the edge 130 is too low, the edge 130 is easily torn during play, causing the toy water ball 1000 to age. The edge 130 of this embodiment is folded, so the structural strength of the edge 130 can be effectively increased to prevent the edge 130 from being torn during play.

[0052] refer to Figure 1-Figure 3 In order to apply a larger and more balanced force to the flexible cover 200 , in a specific embodiment, a plurality of elastic arms 300 are provided, and the plurality of elastic arms 300 are evenly arranged in the circumferential direction of the opening 120 .

[0053] Specifically, increasing the number of elastic arms 300 can exert a greater force on the flexible cover 200, and a plurality of elastic arms 300 evenly arranged in the circumferential direction of the opening 120 can exert a more balanced force on the flexible cover 200. It can be seen that the implementation of this embodiment can improve the sealing performance of the flexible cover 200 and the flexible shell 100 when they are crimped, effectively preventing the water in the water storage chamber 110 from overflowing before the toy water ball 1000 hits the player, and providing an excellent user experience. In a specific embodiment, two, three, or more than three elastic arms 300 can be provided.

[0054] refer to Figure 1-Figure 6 In one embodiment, a plug hole 210 is provided on the side of the flexible cover 200 facing the elastic arm 300, and a plug column 310 is provided on the side of the elastic arm 300 facing the flexible cover 200. The plug column 310 is adapted to the plug hole 210 to connect the elastic arm 300 and the flexible cover 200.

[0055] refer to Figure 1-Figure 6 In a specific embodiment, a first boss 220 is provided on the side of the flexible shell 100 facing the elastic arm 300 , a second boss 230 is provided on the side of the flexible shell 100 facing away from the elastic arm 300 , and the plug hole 210 connects the ends of the first boss 220 and the second boss 230 .

[0056] If the structural strength of the connection between the flexible shell 100 and the elastic arm 300 is too low, the connection between the flexible shell 100 and the elastic arm 300 is easily broken when the toy water ball 1000 is in use, resulting in failure of the toy water ball 1000. The first boss 220 and the second boss 230 can effectively increase the structural strength of the connection between the flexible shell 100 and the elastic arm 300, and reduce the probability of the connection between the flexible shell 100 and the elastic arm 300 breaking when the flexible shell 100 is in use.

[0057] refer to Figure 6 In a specific embodiment, the plug-in column 310 includes a head 311 and a body 312 connected to the head 311, the body 312 is inserted into the plug-in hole 210, the head 311 is located on the side of the plug-in hole 210 close to the water storage chamber 110, and the outer contour of the head 311 is larger than the contour of the plug-in hole 210, so that the elastic arm 300 can be stably clamped together with the flexible cover body 200, and the connection relationship between the two will not be easily released, which can effectively improve the stability of the toy water ball 1000 during use.

[0058] In another embodiment, a glue layer is disposed between the plug-in column 310 and the plug-in hole 210 , and the elastic arm 300 and the flexible cover 200 are stably connected by the glue layer.

[0059] The utility model also provides another toy water ball 1000, such as Figure 7 , Figure 8As shown, the toy water ball 1000 includes a flexible shell 100, a flexible cover 200 and an elastic arm 300. The flexible shell 100 defines a water storage chamber 110 and an opening 120 connecting the water storage chamber 110 with the external space of the flexible shell 100, and a connecting portion 140 is provided on the flexible shell 100. The outer contour of the flexible cover 200 is larger than the contour of the opening 120, and the flexible cover 200 is entirely located in the water storage chamber 110 or at least the edge of the flexible cover 200 extends into the water storage chamber 110 and closes the water storage chamber 110. The elastic arm 300 is disposed on the side of the flexible cover 200 facing the external space and has a connecting end 313. The elastic arm 300 is configured such that when the connecting end 313 is mounted on the connecting portion 140, an outward force is applied to the flexible cover 200, so that the edge of the flexible cover 200 is closely attached to the inner wall of the water storage chamber 110.

[0060] Specifically, since the flexible shell 100 and the flexible cover 200 are both made of flexible materials, the user can apply force to the toy water ball 1000 to make the toy water ball 1000 elastically deform. At this time, the water storage chamber 110 can be exposed by the opening 120, so as to fill the water storage chamber 110 with water. After filling with water, you only need to stop applying force to the toy water ball 1000, and the toy water ball 1000 will restore its deformation. Since the outer contour of the flexible cover 200 is larger than the contour of the opening 120, and the connecting end 313 of the elastic arm 300 will apply an outward force to the flexible cover 200 when it is installed on the connecting part 140, the flexible cover 200 will be close to the inner wall of the water storage chamber 110 under the action of the elastic arm 300, so that the water storage chamber 110 can be well sealed to prevent the water in the water storage chamber 110 from leaking out. When the user throws the toy water ball 1000 and it hits the player, the toy water ball 1000 will be impacted by external force and produce elastic deformation. At this time, the water storage chamber 110 can be exposed by the opening 120, and the water in the water storage chamber 110 will overflow from the opening 120 under the action of external force, causing the player hit by the toy water ball 1000 to be wetted by water.

[0061] Of course, it is understandable that throwing the toy water ball at the player is only a reference way to play the water ball game. In addition to throwing it at the player, the toy water ball 1000 can also be simply thrown at the bottom, wall or other places, and this embodiment is not limited here.

[0062] Compared to magnetic water balls, the water balls of this embodiment do not need built-in magnetic parts, so there is no risk of magnetic parts falling out of the water balls 1000 and being swallowed by children when the water balls are pulled or bitten. Since there is no need for built-in magnetic parts, the production cost is also lower than that of magnetic water balls. Therefore, the water balls 1000 of this embodiment have higher safety and lower production cost.

[0063] Compared to non-magnetic toy water balls, the toy water ball 1000 shown in this embodiment has good sealing properties. Specifically, when the flexible cover 200 covers the opening 120 of the flexible shell 100, the elastic arm 300 applies an outward force to the flexible cover 200, so that the flexible cover 200 is pressed against the inner wall of the water storage chamber 110 under the action of the elastic arm 300, so that the water storage chamber 110 can be well sealed to prevent water in the water storage chamber 110 from leaking out.

[0064] refer to Figure 7 , Figure 8 In a specific embodiment, the elastic arm 300 is integrally formed with the flexible cover 200, thereby achieving the technical effect of reducing the structural complexity of the toy water ball 1000 and reducing the production cost of the toy water ball 1000. The connecting portion 140 includes a connecting column 141 protruding from the outer surface of the flexible shell 100, and the connecting end 313 is provided with a connecting hole 3131, and the connecting hole 3131 is sleeved outside the connecting column 141.

[0065] Specifically, the connection hole 3131 cooperates with the connection column 141 to install the elastic arm 300 on the flexible housing 100 , so that there is no need to provide glue between the connection end 313 and the connection portion 140 , which is beneficial to reduce assembly costs.

[0066] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
