DESCRIPTION OF THE EMBODIMENT

It should be noted that the embodiments in current application and the features in the embodiments may be combined with each other, if there is no conflict. Preferred embodiments of the present disclosure are described in detail in conjunction with the attached drawings.

The embodiment of the present disclosure provides a toy water balloon 1000, as shown in FIG. 1-FIG. 4. The toy water balloon 1000 comprises a flexible shell 100, a flexible cover 200 and an elastic arm 300. The flexible shell 100 limits a water storage cavity 110 and an opening 120 connects the external space of the water storage cavity 110 and the flexible shell 100. The outer contour of the flexible cover 200 is larger than that of the opening 120. The flexible cover 200 is entirely located in the water storage cavity 110 or at least the edge of the flexible cover 200 extends into the water storage cavity 110 and seals the water storage cavity 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 towards the outer space. The elastic arm 300 is configured to apply outward force on the flexible cover 200 so that the edge of the flexible cover 200 sticks closely to the inner wall of the water storage cavity 110.

Particularly, since both the flexible shell 100 and the flexible cover 200 are made of flexible materials, the user can make the toy water balloon 1000 produce elastic deformation by applying force to the toy water balloon 1000. In this case, the water storage cavity 110 can be exposed by the opening 120 to facilitate the filling of water into the water storage cavity 110. After filling the water, it is only needed to stop applying force on the toy water balloon 1000, the toy water balloon 1000 will resume its deformation. Since the outer contour of the flexible cover 200 is larger than that of the opening 120, the elastic arm 300 will apply outward force on the flexible cover 200.

Therefore, the flexible cover 200 will stick close to the inner wall of the water storage cavity 110 under the action of the elastic arm 300. So that the water storage cavity 110 can be well sealed to avoid the water leakage in the water storage cavity 110. When the user throws the toy water balloon 1000 out and hits the player, the toy water balloon 1000 will be impacted by external force and produce elastic deformation. In this case, the water storage cavity 110 can be exposed by the opening 120. The water in the water storage cavity 110 will overflow from the opening 120 under the action of external force resulting in the player hit by the toy water balloon 1000 get wet.

It is understood that throw at the player is only the reference play of the toy water balloon. In addition to throw at the player, it is also possible to simply throw the toy water balloon 1000 to the bottom surface, the wall or other places. The embodiment does not limit the application here.

Compared with a magnetic toy water balloon, the toy water balloon disclosed in this embodiment does not require a built-in magnetic component. There is no risk that the magnetic component will fall out of the toy water balloon when the toy water balloon is pulled or bitten, and be swallowed by a child. Since no built-in magnetic component is required, the production cost is also lower than the magnetic toy water balloon. Thus, the toy water balloon 1000 disclosed in this embodiment has higher safety and lower production cost.

Compared with the non-magnetic toy water balloon, the toy water balloon 1000 disclosed in this embodiment has good sealing properties. Particularly, because when the flexible cover 200 shields the opening 120 of the flexible shell 100, the elastic arm 300 apply outward force on the flexible cover 200. So that the flexible cover 200 will stick close to the inner wall of the water storage cavity 110 under the action of the elastic arm 300. So that the water storage cavity 110 can be well sealed to avoid the water leakage in the water storage cavity 110.

Refer to FIG. 1-FIG. 3, in the embodiment, the elastic arm 300 and the flexible shell 100 are integrally formed. The thickness of the elastic arm 300 is greater than that of the flexible shell 100.

Particularly, the elastic arm 300 and the flexible shell 100 integrally formed not only make the toy water balloon 1000 not easy to damage, but also effectively reduce the structural complexity of the toy water balloon 1000. Thus, the production cost of the toy water balloon 1000 is reduced. The thickness of the elastic arm 300 is greater than that of the flexible shell 100, which is conducive to ensuring that the elastic arm 300 provides sufficient force to the flexible cover 200, so that the water storage cavity 110 can be well sealed.

Refer to FIG. 1-FIG. 3, in the embodiment, the elastic arm 300 is arranged on the outer side of the flexible shell 100 so that the inner wall of the water storage cavity 110 is a spherical or aspherical streamlined curve surface.

Particularly, if the elastic arm 300 is arranged in the flexible shell 100, the elastic arm 300 will protrude from the cavity wall of the water storage cavity 110. This will affect the tightness of the flexible cover 200 and the cavity wall of the water storage cavity 110 to a certain extent. Therefore, the elastic arm 300 is arranged on the outer side of the flexible shell 100 in this embodiment to make the inner wall of the water storage cavity 110 a spherical or aspherical streamlined curve surface, and then improve the sealing performance of the flexible cover 200 and the flexible shell 100 when crimped. This effectively prevents the water in the water storage cavity 110 from overflowing before the toy water balloon 1000 hits the player. The user experience is excellent.

Refer to FIG. 1-FIG. 3, in one embodiment, a flexible shell 100 is provided with an elastic ring 400 near the middle and surrounding the flexible shell 100.

Particularly, the elastic ring 400 is used to apply a force on the toy water balloon 1000 after elastic deformation, causing the toy water balloon 1000 back to round. For example, when the user needs to fill water into the water storage cavity 110, the elastic deformation of the toy water balloon 1000 can be generated by applying a force to the toy water balloon 1000. In this case, the water storage cavity 110 can be exposed by the opening 120 to facilitate the filling of water into the water storage cavity 110. If the force applied when filling water is too large, when the user stops applying force to the toy water balloon 1000, the toy water balloon 1000 is difficult to back to round smoothly. Or the process of the toy water balloon 1000 back to round is very slow. By adding the elastic ring 400, the toy water balloon 1000 can be made to round when the user stops applying force to the toy water balloon 1000, and the user experience is excellent.

Refer to FIG. 1-FIG. 3, in one embodiment, the elastic ring 400 is integrally formed with the flexible shell 100, and the elastic ring 400 protrudes out the inner wall of the water storage cavity 110 or the outer side of the flexible shell 100.

Particularly, the elastic ring 400 and the flexible shell 100 can make the toy water balloon 1000 not easy to damage, but also effectively reduce the structural complexity of the toy water balloon 1000, and thus reduce the production cost of the toy water balloon 1000. In the embodiments where the elastic ring 400 only protrudes from the inner wall of the water storage cavity 110, the elastic ring 400 will not be exposed to the outer surface of the toy water balloon 1000, and the visual experience of the toy water balloon 1000 will be better and more aesthetic. In the embodiments where the elastic ring 400 only protrudes on the outer surface of the flexible shell 100, the elastic ring 400 does not compress the space of the water storage cavity 110, allowing the water storage cavity 110 to contain more water. In the embodiment of the elastic ring 400 protrudes from the inner wall of the water storage cavity 110 and the outer surface of the flexible shell 100, the elastic ring 400 will have greater elasticity and can better promote the process of the toy water balloon 1000 back to round.

Refer to FIG. 1-FIG. 3, in one embodiment, the elastic arm 300 extends on the flexible shell 100 to be connected to the elastic ring 400, so that the elastic arm 300 has higher structural strength and can apply more sufficient force on the flexible cover 200, thereby improving the sealing performance of the flexible cover 200 when crimping the flexible shell 100.

Refer to FIG. 1-FIG. 3, in one embodiment, the flexible shell 100 includes an edge part 130 adjacent to the opening 120, and the edge part 130 folds over in a direction away from the water storage cavity 110.

Particularly, if the structural strength of the edge part 130 is too low, the edge part 130 is easily torn during play, resulting in failure of the toy water balloon 1000. In this embodiment, the edge part 130 folds over so that the structural strength of the edge part 130 can be effectively increased to avoid the edge part 130 being torn during play.

To apply a greater and more balanced force on the flexible cover 200, in one embodiment, the elastic arm 300 is provided with plurality of elastic arms. The multiple elastic arms 300 are uniformly arranged on the circumference of the opening 120.

Particularly, increasing the number of elastic arms 300 can apply a greater force on the flexible cover 200. Multiple elastic arms 300 are uniformly arranged on the circumference of the opening 120 can apply 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 when crimped with the flexible shell 100. This will effectively prevent the water in the water storage cavity 110 from overflowing before the toy water balloon 1000 hits the player, and the user experience is excellent. In one embodiment, the elastic arm 300 may be provided with two, three or more.

Refer to FIG. 1-FIG. 6, in one embodiment, the side of the flexible cover 200 toward the elastic arm 300 is provided with an inserting hole 210, and the side of the elastic arm 300 toward the flexible cover 200 is provided with an inserting column 310. The inserting column 310 is adapted to the inserting hole 210 to connect the elastic arm 300 to the flexible cover 200.

Refer to FIG. 1-FIG. 6, in one embodiment, the side of the flexible shell 100 toward the elastic arm 300 is provided with a first lug boss 220, the side of the flexible shell 100 toward the elastic arm 300 is provided with a second lug boss 230. The inserting hole 210 is connected to the end of the first lug boss 220 and the second lug boss 230.

If the structural strength of the connection position between the flexible shell 100 and the elastic arm 300 is too low, the connection position of the flexible shell 100 and the elastic arm 300 will easily break when the toy water balloon 1000 is used, resulting in the failure of the toy water balloon 1000. The first lug boss 220 and the second lug boss 230 can effectively increase the structural strength at the connection position between the flexible shell 100 and the elastic arm 300 and reduce the probability that the connection position between the flexible shell 100 and the elastic arm 300 will break when the flexible shell 100 is in use.

Refer to FIG. 6, in one embodiment, the inserting column 310 comprises a head 311 and a body 312 connected to the head 311. The body 312 is threaded through the inserting hole 210. The head 311 is located on the side of the inserting hole 210 near the water storage cavity 110, and the outer contour of the head 311 is larger than the outer contour of the inserting hole 210 to make the elastic arm 300 and the flexible cover 200 stably clamp together. The connection between the two will not be easily removed, which can effectively improve the stability of the toy water balloon 1000 in use.

In another embodiment, a glue layer is arranged between the inserting column 310 and the inserting hole 210. The elastic arm 300 is stably connected to the flexible cover 200 by means of the glue layer.

The present application further discloses another toy water balloon 1000, as shown in FIG. 7 and FIG. 8. The toy water balloon 1000 comprises a flexible shell 100, a flexible cover 200 and an elastic arm 300. The flexible shell 100 limits a water storage cavity 110 and an opening 120 connects the external space of the water storage cavity 110 and the flexible shell 100. The flexible shell 100 is provided with a connection part 140. The outer contour of the flexible cover 200 is greater than the outer contour of the opening 120, the flexible cover 200 is entirely located in the water storage cavity 110 or at least the edge of the flexible cover 200 extends into the water storage cavity 110 and seals the water storage cavity 110. The elastic arm 300 is arranged on the side of the flexible cover 200 toward an external space and has a connection end 313. The elastic arm 300 is configured to apply outward force on the flexible cover 200 when the connection end 313 is installed on the connection part 140. So that the edge of the flexible cover 200 stick closely to the inner wall of the water storage cavity 110.

Particularly, since both the flexible shell 100 and the flexible cover 200 are made of flexible materials, the user can make the toy water balloon 1000 produce elastic deformation by applying force to the toy water balloon 1000. In this case, the water storage cavity 110 can be exposed by the opening 120 to facilitate the filling of water into the water storage cavity 110. After filling the water, it is only needed to stop applying force on the toy water balloon 1000, and the deformation of the toy water balloon 1000 will resume. Because the outer contour of the flexible cover 200 is larger than that of the opening 120, and the connection end 313 of the elastic arm 300 will apply outward force on the flexible cover 200 when it is installed in the connection part 140. Therefore, the flexible cover 200 will stick closely to the inner wall of the water storage cavity 110 under the action of the elastic arm 300, so that the water storage cavity 110 can be well sealed to avoid the water leakage in the water storage cavity 110. When the user throws the toy water balloon 1000 out and hits the player, the toy water balloon 1000 will be impacted by external force and produce elastic deformation. In this case, the water storage cavity 110 can be exposed by the opening 120, and the water in the water storage cavity 110 will overflow from the opening 120 under the action of external force, resulting in the player hit by the toy water balloon 1000 get wet.

It is understood that throw at the player is only the reference play of the toy water balloon. In addition to throw at the player, it is also possible to simply throw the toy water balloon 1000 to the bottom surface, the wall or other places. The embodiment does not limit the application here.

There is no risk that the magnetic component will fall out of the toy water balloon when the toy water balloon is pulled or bitten, and be swallowed by a child. Since no built-in magnetic component is required, the production cost is also lower than the magnetic toy water balloon. Thus, the toy water balloon 1000 disclosed in this embodiment has higher safety and lower production cost.

Compared with the non-magnetic toy water balloon, the toy water balloon 1000 disclosed in this embodiment has good sealing properties. Particularly, because when the flexible cover 200 shields the opening 120 of the flexible shell 100, the elastic arm 300 apply outward force on the flexible cover 200. So that the flexible cover 200 will stick close to the inner wall of the water storage cavity 110 under the action of the elastic arm 300. So that the water storage cavity 110 can be well sealed to avoid the water leakage in the water storage cavity 110.
