Description

Technical Field

[0001] The utility model relates to the technical field of entertainment toys, in particular to an entertainment water ball. Background Art

[0002] Water balls for entertainment are amusement water toys commonly used in water parks or swimming pools. The overall weight of water balls is usually relatively light. The water balls are connected by two hemispheres to form a hollow water storage cavity inside. Before throwing the water balls, water is added to the water storage cavity to increase the weight of the water balls, so that the water balls can be thrown farther. The purpose of interactive play is achieved by throwing water balls to each other.

[0003] With the update and iteration of products, there are more and more types of water balls, but the existing water balls still have the following defects:

[0004] 1. When water is poured into the water storage chamber of the existing toy water ball, the water storage chamber will be completely filled. After being filled with water, the weight of the water ball is too heavy and often sinks directly to the bottom of the water; when children play with water balls, they will unconsciously sink to the bottom of the water to pick up the water balls, so there is a situation of drowning due to picking up the balls, which leads to safety accidents;

[0005] In addition, it is difficult to determine the water storage amount when filling the water storage chamber of the water ball. When too much water is filled in the water storage chamber, the water ball is too heavy, or when too little water is filled in the water storage chamber, the water ball is too light, both of which will cause the water ball to be thrown not far, reducing the user experience.

[0006] 2. The two hemispheres of the existing toy water balls are usually sealed and connected by means of magnetic attraction or interlocking. However, during use, the connection between the two hemispheres may not be sealed well, which may easily lead to water leakage.

[0007] 3. The outer surface of the existing toy water balls is usually set to be relatively smooth, which makes it easy to hold the water balls unsteadily when throwing them to each other. Utility Model Content

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] like Figure 1-9 As shown, a recreational water ball is used as an amusement water toy for use in water parks or swimming pools. The water ball includes a first hemisphere 10, a second hemisphere 11 and a buoyancy cover 20. It can be seen that the overall shape structure of the first hemisphere 10 and the second hemisphere 11 are both set as hollow hemispheres. A connecting surface 110 is set on the side of the inner walls of the first hemisphere 10 and the second hemisphere 11 close to each other. Since the first hemisphere 10 and the second hemisphere 11 are both hemisphere structures, a ring-shaped connecting surface 110 is set on the side of the first hemisphere 10 and the second hemisphere 11. A connecting structure 30 is set on the connecting surface 110, and the first hemisphere 10 and the second hemisphere 11 are detachably sealed and connected through the connecting structure 30.

[0041] The first hemisphere 10 and the second hemisphere 11 are relatively connected to form a spherical structure with a water storage chamber 114 inside. In actual operation, water is first poured into the water storage chamber 114 and then the first hemisphere 10 and the second hemisphere 11 are relatively spliced ​​and connected. The first hemisphere 10 and the second hemisphere 11 can also be completely immersed in water and spliced ​​and connected to fill the water storage chamber 114 with water. The amount of water filled in the water storage chamber 114 can be controlled by the user.

[0042] The buoyancy cover 20 is arranged on the inner wall of the first hemisphere 10 and / or the second hemisphere 11, and the buoyancy cover 20 is sealedly connected with the inner wall of the first hemisphere 10 and / or the second hemisphere 11 to form a buoyancy cavity 202 for adjusting the buoyancy of the water ball. Therefore, by reserving air in the buoyancy cavity 202, the entire water ball can float on the water surface.

[0043] In this way, a buoyancy cavity 202 is formed by sealingly connecting the buoyancy cover 20 with the inner wall of the first hemisphere 10 and / or the second hemisphere 11. The buoyancy cavity 202 occupies a certain proportion of the volume of the water storage cavity 114 in the water ball. Air is pre-stored in the buoyancy cavity 202 to provide a buoyancy basis for the water ball. Even if the water storage cavity 114 is filled with water, the water ball will still float on the water surface. This avoids the risk of sinking to the bottom of the water after being filled with water like previous water balls, which would cause the user to drown. This ensures the user's safe use.

[0044] In the embodiment of the present application, the overall shape structure of the buoyancy cover 20 is set to be a hollow hemisphere, and the edge of the buoyancy cover 20 is provided with an outwardly turned sealing groove 201, and a fitting edge extending outward is also provided around the outer side of the sealing groove 201. The inner wall of the first hemisphere 10 and / or the second hemisphere 11 is provided with a ring-shaped sealing rib 111, and the sealing rib 111 is formed by an integral protrusion of the inner wall of the first hemisphere 10 or the second hemisphere 11.

[0045] Therefore, the buoyancy cover 20 is detachably sealed and connected to the inner wall of the first hemisphere 10 and / or the second hemisphere 11 through the sealing buckle of the sealing slot 201 and the sealing rib 111. When the sealing slot 201 is sealed and buckled with the sealing rib 111, the fitting edges around the sealing slot 201 are tightly fitted with the inner wall of the hemisphere, further improving the sealing connection effect between the buoyancy cover 20 and the inner wall of the sphere. By assembling the buoyancy cover 20 on the inner wall of the first hemisphere 10 or the second hemisphere 11, the buoyancy cavity 202 is formed between the buoyancy cover 20 and the inner wall of the first hemisphere 10 or the second hemisphere 11.

[0046] In addition, in addition to the sealed snap connection between the buoyancy cover 20 and the inner wall of the first hemisphere 10 and / or the second hemisphere 11, a one-time detachable sealing adhesive can also be selected. When the buoyancy cover 20 needs to be replaced, the buoyancy cover 20 is directly torn off, and then a new sealant is used to glue the new buoyancy cover 20 to the inner wall of the sphere.

[0047] In this way, the user can install buoyancy covers 20 of different sizes according to the amount of water in the water storage chamber 114, thereby forming buoyancy chambers 202 of different volumes. In actual use, the volume ratio of the buoyancy chamber 202 to the water storage chamber 114 is 1-3:10. Preferably, the volume ratio of the buoyancy chamber 202 to the water storage chamber 114 is 3:10. At this time, the water ball can be thrown the farthest with the least effort.

[0048] Through the detachable connection between the buoyancy cover 20 and the inner wall of the ball, the user can adjust the water volume in the water storage chamber 114 by replacing the buoyancy cover 20 of different sizes, eliminating the trouble of being unable to control the water volume of the water ball in the past; thereby controlling the total weight of the water ball and adjusting the total weight of the water ball to a weight suitable for the throwing needs of different users, thereby improving the user experience.

[0049] In the embodiment of the present application, the connection structure 30 has an annular assembly pad 301, a magnetic body 303 and a sealing gasket 304. Two annular assembly pads 301 are provided. The two annular assembly pads 301 are respectively connected to the connection surface 110 of the first hemisphere 10 and the second hemisphere 11, and one side of the two annular assembly pads 301 is integrally softly connected through a soft part 302, so that the two annular assembly pads 301 can be folded and overlapped at will and relatively detachably sealed. By providing an arc-shaped groove 3021 on the bending side of the soft part 302, the bending convenience and anti-fatigue effect of the soft part 302 during repeated bending can be improved.

[0050] The annular direction of the annular assembly pad 301 is provided with a mounting groove 3011 for mounting the magnetic body 303. Specifically, the mounting groove 3011 has a plurality of grooves, and the plurality of grooves 3011 are equidistantly provided in the annular direction of the annular assembly pad 301, and the mounting groove 3011 is provided on the side where the annular assembly pad 301 is connected to the connecting surface 110 of the sphere. Since the annular direction of the annular assembly pad 301 is provided with a plurality of grooves 3011, each of the grooves 3011 is provided with a corresponding magnetic body 303.

[0051] In addition, according to the use requirements of customers, an annular mounting groove 3011 with an annular shape and structure can be opened on the annular assembly pad 301, and then the annular magnetic body 303 with an annular structure can be installed accordingly.

[0052] Furthermore, a sealing gasket 304 is provided between the annular assembly gasket 301 and the connection surface 110 of the first hemisphere 10 and the second hemisphere 11 , so that the sealing connection effect between the annular assembly gasket 301 and the first hemisphere 10 and the second hemisphere 11 is better.

[0053] In order to meet the user's safety requirements, the first hemisphere 10, the second hemisphere 11, the buoyancy cover 20 and the annular assembly pad 301 are made of food-grade plastic or food-grade silicone, wherein food-grade plastics include PET, PP, HDPE, LDPE, PS, PC, PVC and other materials.

[0054] Thus, by arranging the magnetic body 303 on the annular assembly pad 301 of the connection structure 30, the first hemispherical body 10 and the second hemispherical body 11 can be more conveniently attracted and separated by magnetic attraction. Moreover, the annular assembly pad 301 is provided with an installation groove 3011, through which the magnetic body 303 can be conveniently installed or replaced. The magnetic body 303 is arranged according to the annular direction of the annular assembly pad 301, so that each position of the connection surface 110 of the first hemispherical body 10 and the second hemispherical body 11 can be evenly sealed and connected to avoid water leakage.

[0055] The surface of the first hemisphere 10 and / or the second hemisphere 11 is provided with a plurality of anti-skid grooves 112 connected end to end or a plurality of anti-skid recesses 113 distributed randomly, and the anti-skid grooves 112 and the anti-skid recesses 113 are both formed by being integrally sunken inwardly on the surface of the sphere. It is also possible to choose to simultaneously provide the anti-skid grooves 112 and the anti-skid recesses 113 on the surface of the sphere, in which case the anti-skid recesses 113 are distributed in the closed area formed by the anti-skid grooves 112 connected end to end, thereby forming an anti-skid structure that increases the gripping friction effect.

[0056] In this way, by providing the anti-skid groove 112 and / or the anti-skid recess 113 on the surface of the first hemisphere 10 and / or the second hemisphere 11, the friction force when the user grabs the water ball is increased, so that the user can get a better playing experience.

[0057] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
