Description

Technical Field

[0001] The present invention relates to the technical field of water equipment, and particularly to a buoyancy structure and a water equipment. Background Art

[0002] Playing in a swimming pool is one of the favorite pastimes of children. To better enrich the fun of children playing in the water, various buoyancy toys have emerged on the market. Most buoyancy toys mainly use their own buoyancy structures to enable the buoyancy toys to float on the water surface for children to play with.

[0003] However, when children play with buoyancy toys in the water, since the buoyancy structure floats on the water surface and is easily affected by the water fluctuations in the swimming pool and moves, the fixity of the buoyancy toy in the water is poor. As a result, when children grab the buoyancy toy in the water, it is easy to miss, and thus it cannot be ensured that children can quickly and accurately grab the buoyancy toy in the water, and there is a difficult grabbing phenomenon.

[0004] For example, CN203710687U discloses a negative buoyancy water toy having a water-sealed body part, which includes a battery electrically connected to at least one coil through a controller. The coil is associated with a magnet, and the coil can swing due to the action of the controller, and the controller is used to determine the alternating current passing through the coil. The swing of the coil causes the tail fin combined with the water-sealed body to move, and further enables the toy to move upward through the water body, so as to make the tail fin of the water-sealed body move through the controller. Not only is the structure complex and the cost high, but also the negative buoyancy water toy moving in the water will further increase the difficulty for children to grab. Therefore, how to improve the fixity of the buoyancy toy in the water for children to grab is an urgent problem to be solved at present. Summary of the Invention

[0005] An object of the present invention is to overcome the deficiencies in the prior art, and to provide a buoyancy structure and a water equipment that improve the fixity of the buoyancy structure in the water to ensure that children can quickly and accurately grab it, and have good hygiene and waterproof performance.

[0006] The object of the present invention is achieved by the following technical solutions:

[0007] A buoyancy structure, comprising:

[0008] An outer covering component, the outer covering component includes a first cloth body and a second cloth body, and a sewing thread is arranged between the second cloth body and the second cloth body, and the sewing thread is used to sew the first cloth body and the second cloth body to form a receiving cavity;

[0010] The counterweight sandbag includes a first waterproof bag, a first tying member and a counterweight portion. The first waterproof bag forms a first cavity and a first opening. The counterweight portion is received in the first cavity, and the first tying member is used to tightly tie and seal the first opening of the first cavity;

[0011] The counterweight cotton bag includes a second waterproof bag, a second tying member and a cotton wadding portion. The second waterproof bag forms a second cavity and a second opening. The cotton wadding portion is received in the second cavity, and the second tying member is used to tightly tie and seal the second opening of the second cavity;

[0012] The counterweight magnetic bag includes a third waterproof bag, a third tying member and a first magnetic body. The third waterproof bag forms a third cavity and a third opening. The first magnetic member is located in the third cavity, and the third tying member is used to tightly tie and seal the third opening.

[0013] In one embodiment, the first magnetic body is a magnetic bead.

[0014] In one embodiment, the counterweight portion is sand; and / or,

[0015] The cotton wadding portion is plush cotton or pearl cotton.

[0016] In one embodiment, the first tying member is a nylon tie; and / or,

[0017] The second tying member is a nylon tie.

[0018] In one embodiment, the first fabric body includes a first plastic elastic layer, a first glue layer and a first waterproof layer, and the first plastic elastic layer is adhesively connected to the first waterproof layer through the first glue layer.

[0019] In one embodiment, the thickness of the first plastic elastic layer is 1.0 mm to 3.0 mm.

[0020] In one embodiment, the second fabric body includes a second plastic elastic layer, a second glue layer and a second waterproof layer, and the second plastic elastic layer is adhesively connected to the second waterproof layer through the second glue layer.

[0021] In one embodiment, the thickness of the second plastic elastic layer is 1.0 mm to 3.0 mm.

[0022] In one of the embodiments, the counterweight assembly further includes at least two partition sheets, each of the partition sheets is arranged at intervals in the accommodation cavity, and a first sub-cavity, a second sub-cavity and a third sub-cavity are formed in the accommodation cavity. The first sub-cavity is used to accommodate the counterweight cotton bag, the second sub-cavity is used to accommodate the counterweight sand bag, and the third sub-cavity is used to accommodate the counterweight magnetic bag.

[0023] An aquatic device includes the buoyancy structure described in any one of the above embodiments.

[0024] Compared with the prior art, the present invention has at least the following advantages:

[0025] 1. For the above-mentioned buoyancy structure, the first cloth body and the second cloth body are sewn together by sewing threads to form an outer covering assembly of a toy prototype required for production, and an accommodation cavity is formed on the outer covering assembly to accommodate a counterweight sand bag, a counterweight cotton bag and a counterweight magnetic bag. Since the density of the counterweight sand bag and the counterweight magnetic bag is greater than that of water, and the density of the counterweight cotton bag is less than that of water, when the buoyancy structure is placed in water, the counterweight sand bag and the counterweight magnetic bag will sink into the water, while the counterweight cotton bag will float on the water surface to reduce the movement of the buoyancy structure caused by water fluctuations, that is, a larger water fluctuation is required for the buoyancy structure to move, thereby improving the fixity of the buoyancy toy in water. Further, since the counterweight magnetic bag is provided with a first magnetic body, when the buoyancy structure is placed in a swimming pool provided with a second magnetic body, the first magnetic body of the counterweight magnetic bag can be magnetically attracted to the second magnetic body of the swimming pool, further improving the fixing effect of the buoyancy structure in water and further improving the fixity of the buoyancy toy in water to ensure that children can quickly and accurately grab the buoyancy structure in water to avoid the phenomenon of difficult grabbing. In addition, since the outer covering assembly is provided with a counterweight cotton bag, a counterweight sand bag and a counterweight magnetic bag, the buoyancy structure realizes self-balancing in water through the counterweight cotton bag, the counterweight sand bag and the counterweight magnetic bag, which is not only simple in structure but also low in cost.

[0026] 2. In the above buoyancy structure, since the outer covering component houses the counterweight sandbag, the counterweight cotton bag, and the first magnetic component in the accommodation cavity, the outer covering component can effectively block moisture from entering the interior, thereby reducing the phenomenon that bacteria easily grow inside the buoyancy structure. Also, since the counterweight sandbag includes a first waterproof bag, a counterweight portion, and a first tying member, the counterweight portion can be sealed inside the first waterproof bag; the counterweight cotton bag includes a second waterproof bag, a second tying member, and a cotton wool portion, so that the cotton wool portion can be sealed inside the second waterproof bag; the counterweight magnetic bag includes a third waterproof bag, a third tying member, and a first magnetic body, so that the first magnetic body can be sealed inside the third waterproof bag, further preventing moisture from entering the counterweight portion, the cotton wool portion, and the first magnetic body, ensuring that the counterweight portion, the cotton wool portion, and the first magnetic body can be maintained in a relatively dry environment. In this way, on the one hand, it ensures that the counterweight component can provide a relatively constant buoyancy for the buoyancy structure, and on the other hand, it prevents moisture from entering the counterweight portion, the cotton wool portion, and the first magnetic component, which is likely to cause bacteria growth in the counterweight component, thereby improving the hygiene of the buoyancy structure.

[0036] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention can be understood more thoroughly and comprehensively.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] The present application provides a buoyancy structure, including an outer covering component and a counterweight component. The outer covering component includes a first fabric body and a second fabric body. A sewing thread is arranged between the first fabric body and the second fabric body, and the sewing thread is used to sew the first fabric body and the second fabric body to form a receiving cavity. The counterweight component includes a counterweight sandbag, a counterweight cotton bag, and a counterweight magnetic attraction bag. The counterweight cotton bag, the counterweight sandbag, and the counterweight magnetic attraction bag are sequentially arranged in the receiving cavity. The counterweight sandbag includes a first waterproof bag, a first tying member, and a counterweight portion. The first waterproof bag forms a first cavity and a first opening. The counterweight portion is received in the first cavity, and the first tying member is used to tightly tie and close the first opening of the first cavity. The counterweight cotton bag includes a second waterproof bag, a second tying member, and a cotton wool portion. The second waterproof bag forms a second cavity and a second opening. The cotton wool portion is received in the second cavity, and the second tying member is used to tightly tie and close the second opening of the second cavity. The counterweight magnetic attraction bag includes a third waterproof bag, a third tying member, and a first magnetic body. The third waterproof bag forms a third cavity and a third opening. The first magnetic member is located in the third cavity, and the third tying member is used to tightly tie and close the third opening for positioning.

[0040] The above buoyancy structure sews the first fabric body and the second fabric body into an outer covering assembly of a toy prototype required for production through sewing threads, and a receiving cavity is formed on the outer covering assembly to accommodate a weight sandbag, a weight cotton bag, and a weight magnetic attraction bag. Since the density of the weight sandbag and the weight magnetic attraction bag is greater than that of water, and the density of the weight cotton bag is less than that of water, when the buoyancy structure is placed in water, the weight sandbag and the weight magnetic attraction bag will sink into the water, while the weight cotton bag will float on the water surface to reduce the movement of the buoyancy structure caused by water fluctuations, that is, the buoyancy structure requires larger water fluctuations to cause the buoyancy structure to move, thereby improving the fixity of the buoyancy toy in water. Further, since the weight magnetic attraction bag is provided with a first magnetic attraction body, when the buoyancy structure is placed in a swimming pool provided with a second magnetic attraction body, the first magnetic attraction body of the weight magnetic attraction bag can be magnetically attracted to the second magnetic attraction body of the swimming pool, further improving the fixing effect of the buoyancy structure in water and further improving the fixity of the buoyancy toy in water to ensure that children can quickly and accurately grab the buoyancy structure in water to avoid the phenomenon of difficult grabbing. In addition, since the weight cotton bag, the weight sandbag, and the weight magnetic attraction bag are arranged inside the outer covering assembly, the buoyancy structure realizes self-balancing in water through the weight cotton bag, the weight sandbag, and the weight magnetic attraction bag, which is not only simple in structure but also low in cost. Further, for the above buoyancy structure, since the outer covering assembly houses the weight sandbag, the weight cotton bag, and the first magnetic attraction member in the receiving cavity, the outer covering assembly can effectively block moisture from entering the interior, thereby reducing the phenomenon that bacteria are likely to grow inside the buoyancy structure. Also, since the weight sandbag includes a first waterproof bag, a weight portion, and a first tying member, the weight portion can be sealed in the first waterproof bag, the weight cotton bag includes a second waterproof bag, a second tying member, and a cotton wool portion, so that the cotton wool portion can be sealed in the second waterproof bag, and the weight magnetic attraction bag includes a third waterproof bag, a third tying member, and a first magnetic attraction body, so that the first magnetic attraction body can be sealed in the third waterproof bag, further preventing moisture from entering the weight portion, the cotton wool portion, and the first magnetic attraction body to ensure that the weight portion, the cotton wool portion, and the first magnetic attraction body can be maintained in a relatively dry environment. In this way, on the one hand, it ensures that the buoyancy structure of the weight assembly can provide relatively constant buoyancy to ensure that the buoyancy structure still maintains relatively stable buoyancy during long-term use and ensure that the buoyancy structure can float in water in a self-balanced manner. On the other hand, it avoids moisture entering the weight portion, the cotton wool portion, and the first magnetic attraction member, which is likely to cause bacteria to grow in the weight assembly, thereby improving the hygiene of the buoyancy structure.

[0041] To better understand the technical solutions and beneficial effects of the present application, the following further elaborates on the present application with specific embodiments:

[0042] As Figures 1 to 3As shown, the buoyancy structure 10 in one embodiment includes an outer covering component 100 and a counterweight component 200. The outer covering component 100 includes a first fabric body 110 and a second fabric body 120. A sewing thread 130 is provided between the first fabric body 110 and the second fabric body 120. The sewing thread 130 is used to sew the first fabric body 110 and the second fabric body 120 to form a receiving cavity. The counterweight component 200 includes a counterweight sandbag 210, a counterweight cotton bag 220, and a counterweight magnetic attraction bag 230. The counterweight cotton bag 220, the counterweight sandbag 210, and the counterweight magnetic attraction bag 230 are sequentially arranged in the receiving cavity. The counterweight sandbag 210 includes a first waterproof bag 211, a first tying member 212, and a counterweight portion 213. The first waterproof bag 211 forms a first cavity and a first opening. The counterweight portion 213 is received in the first cavity. The first tying member 212 is used to tightly tie and seal the first opening of the first cavity. The counterweight cotton bag 220 includes a second waterproof bag 221, a second tying member 222, and a cotton wool portion 223. The second waterproof bag 221 forms a second cavity and a second opening. The cotton wool portion 223 is received in the second cavity. The second tying member 222 is used to tightly tie and seal the second opening of the second cavity. The counterweight magnetic attraction bag 230 includes a third waterproof bag 231, a third tying member 232, and a first magnetic body 233. The third waterproof bag 231 forms a third cavity and a third opening. The first magnetic body 233 is located in the third cavity. The third tying member 232 is used to tightly tie and seal the third opening.

[0043] The above-mentioned buoyancy structure 10 sews the first fabric body 110 and the second fabric body 120 with a sewing thread 130 to form an outer covering assembly 100 of a toy prototype required for production, and a receiving cavity is formed on the outer covering assembly 100 to accommodate a weight sandbag 210, a weight cotton bag 220, and a weight magnetic attraction bag 230. Since the density of the weight sandbag 210 and the weight magnetic attraction bag 230 is greater than that of water 24, and the density of the weight cotton bag 220 is less than that of water 24, when the buoyancy structure 10 is placed in water 24, the weight sandbag 210 and the weight magnetic attraction bag 230 will sink into the water 24, while the weight cotton bag 220 will float on the water surface of the water 24, so as to reduce the movement of the buoyancy structure 10 caused by the fluctuation of the water 24, that is, a larger fluctuation of the water 24 is required for the buoyancy structure 10 to move, thereby improving the fixity of the buoyancy toy in the water 24. Further, since the weight magnetic attraction bag 230 is provided with a first magnetic attraction body 233, when the buoyancy structure 10 is placed in a swimming pool 22 provided with a second magnetic attraction body 23, the first magnetic attraction body 233 of the weight magnetic attraction bag 230 can magnetically attract with the second magnetic attraction body 23 of the swimming pool 22, further improving the fixing effect of the buoyancy structure 10 in the water 24 and further improving the fixity of the buoyancy structure 10 in the water 24, so as to ensure that children can quickly and accurately grab the buoyancy structure 10 in the water 24 and avoid the phenomenon of difficult grabbing. In addition, since the weight cotton bag 220, the weight sandbag 210, and the weight magnetic attraction bag 230 are arranged in the outer covering assembly 100, the buoyancy structure 10 realizes self-balancing in the water 24 through the weight cotton bag 220, the weight sandbag 210, and the weight magnetic attraction bag 230, which is not only simple in structure but also low in cost.

[0044] Furthermore, for the above-mentioned buoyancy structure 10, since the outer covering component 100 houses the counterweight sandbag 210, the counterweight cotton bag 220, and the first magnetic body 233 in the accommodation cavity, the outer covering component 100 can effectively block moisture from entering the interior, thereby reducing the phenomenon of bacteria growth prone to occur inside the buoyancy structure 10. Also, since the counterweight sandbag 210 includes a first waterproof bag 211, a counterweight portion 213, and a first tying member 212, the counterweight portion 213 can be sealed inside the first waterproof bag 211. The counterweight cotton bag 220 includes a second waterproof bag 221, a second tying member 222, and a cotton wool portion 223, so that the cotton wool portion 223 can be sealed inside the second waterproof bag 221. The counterweight magnetic bag 230 includes a third waterproof bag 231, a third tying member 232, and a first magnetic body 233, so that the first magnetic body 233 can be sealed inside the third waterproof bag 231, further preventing moisture from entering the counterweight portion 213, the cotton wool portion 223, and the first magnetic body 233, ensuring that the counterweight portion 213, the cotton wool portion 223, and the first magnetic body 233 can be maintained in a relatively dry environment. In this way, on the one hand, it ensures that the buoyancy structure 10 of the counterweight assembly 200 can provide relatively constant buoyancy, ensuring that the buoyancy structure 10 still maintains relatively stable buoyancy during long-term use, ensuring that the buoyancy structure 10 can float in the water 24 in a self-balanced manner. On the other hand, it prevents moisture from entering the counterweight portion 213, the cotton wool portion 223, and the first magnetic body 233, which is likely to cause bacteria growth in the counterweight assembly 200, thereby improving the hygiene of the buoyancy structure 10.

[0045] In one embodiment, the first magnetic body 233 is a magnetic bead. It can be understood that due to the relatively stable magnetic attraction of the magnetic bead, the magnetic bead still has good magnetic attraction performance after long-term use, extending the service life of the buoyancy structure 10.

[0046] In one embodiment, the number of the magnetic beads is multiple, and each of the magnetic beads is filled in the third waterproof bag 231, so that the multiple magnetic beads can be well filled in the third waterproof bag 231, ensuring that the buoyancy structure 10 can be positioned in the water 24.

[0047] Furthermore, in this embodiment, the magnetic bead is a first rubber magnetic bead 2331. Since the surface of the first rubber magnetic bead 2331 is coated with a first rubber layer, it prevents water 24 from entering the first rubber magnetic bead 2331, and prevents the metal material of the first rubber magnetic bead 2331 from rusting easily, resulting in a decrease in the magnetism of the first rubber magnetic bead 2331. Therefore, the present invention uses the first rubber magnetic bead 2331 to avoid the phenomenon of easy rusting of the first rubber magnetic bead 2331, ensuring the service life of the buoyancy structure 10. Further, in this embodiment, the first rubber magnetic bead 2331 includes a ferrite magnetic bead and a first rubber layer coated on the ferrite magnetic bead, so that the first rubber layer can block moisture from entering the ferrite magnetic bead, thereby ensuring the magnetic ability of the ferrite magnetic bead.

[0048] In this embodiment, the particle size of the first rubber magnetic bead 2331 is 1 mm to 3 mm. It can be understood that by setting the particle size of the first rubber magnetic bead 2331 to 1 mm to 3 mm, the first rubber magnetic bead 2331 can be well filled in the third waterproof bag 231 to ensure a higher-density counterweight magnetic attraction bag 230, so as to reduce the flow rate of moisture in the first magnetic attraction body 233, thereby effectively preventing moisture from entering the inside of the first magnetic attraction body 233, slowing down the rusting speed of the first magnetic attraction body 233, and further extending the service life of the first magnetic attraction body 233. Further, when the gaps between the first rubber magnetic beads 2331 are relatively large, it is easy for the multiple first rubber magnetic beads 2331 to shake in the third cavity with the fluctuation of water, resulting in a large frictional force between the first rubber magnetic beads 2331. Therefore, the frictional force between each first rubber magnetic bead 2331 and the third waterproof bag 231 and the frictional force between the first rubber magnetic beads 2331 are effectively reduced, avoiding the phenomenon that the third waterproof bag 231 is easily damaged and the phenomenon that each first rubber magnetic bead 2331 is easily worn, thereby better ensuring the service life of the counterweight magnetic attraction bag 230.

[0049] Further, since the first rubber magnetic bead 2331 is spherical, the first rubber magnetic beads 2331 are in arc contact with each other and the first rubber magnetic beads 2331 are in arc contact with the third waterproof bag 231. In this way, not only is the frictional force between the first rubber magnetic beads 2331 small, but also the frictional force between the first rubber magnetic beads 2331 and the third waterproof bag 231 is small, thereby further reducing the wear between the first rubber magnetic beads 2331 and the wear between the first rubber magnetic beads 2331 and the third waterproof bag 231, and better ensuring the service life of the counterweight magnetic attraction bag 230.

[0050] In this embodiment, the first rubber layer is a PTFE (Polytetrafluoroetylene) layer. It can be understood that since the polytetrafluoroethylene first rubber layer has good abrasion resistance, and since the water 24 in the swimming pool 22 contains disinfectant water 24, by setting the first rubber layer as a PTFE layer, the abrasion resistance of the first rubber layer is improved, thereby preventing the water 24 in the swimming pool 22 from damaging the first rubber layer and ensuring that the first rubber layer can effectively block moisture from entering the ferrite magnetic beads. Further, since the friction coefficient of the PTFE layer is small, the frictional force between the first rubber layer and each first rubber magnetic bead 2331 is small, further reducing the wear between the first rubber magnetic beads 2331 and the wear between each first rubber magnetic bead 2331 and the third waterproof bag 231.

[0051] In order to position the buoyant structure 10 in the water 24, in one embodiment, the vertical force applied to the first magnetic body 233 is equal to the weight G of the buoyant structure 10 itself. 浮力结构 The sum of the attraction force F2 of the second magnetic body 23, the vertical force of the second magnetic body 23, the support force F3 of the second magnetic body 23, the ground support force F5, the gravity G of the second magnetic body 23 itself, and the vertical force F3 of the second magnetic body 23. 第二磁吸体 , the pressure G of the buoyancy structure 10 浮力结构 The attraction F4 of the first magnetic body 233, that is, F3 = F5 + F4 - G 第二磁吸体 -G 浮力结构 , so that F5+F4-G 第二磁吸体 -G 浮力结构 A balance is reached, so that the resultant force of F1 and F3 is zero, so that the buoyant structure 10 and the second magnetic body 23 of the swimming pool 22 can maintain balance, so that the buoyant structure 10 can be positioned in the water 24.

[0052] In one embodiment, the counterweight portion 213 is sand. On the one hand, sand can provide a better hand feel for the user. On the other hand, sand is relatively cheap, thereby reducing the production cost of the buoyancy structure 10. On the other hand, sand has good weather resistance and is not easy to breed bacteria, thereby improving the sanitary performance of the buoyancy structure 10.

[0053] Furthermore, in one embodiment, the cotton portion 223 is made of cotton wool or pearl cotton to ensure that the buoyancy structure 10 can achieve self-balancing in the water 24 when used in conjunction with sand, thereby maintaining its position in the water. The shape of the buoyancy structure 10 can be diverse. In this embodiment, the outer cover assembly 100 is fan-shaped to obtain the desired shape of the buoyancy structure 10 to meet the requirements of different users. Of course, the outer cover assembly 100 can also be rectangular or square, etc., to further increase the diversity of the buoyancy structure 10.

[0054] In one embodiment, the first tying member 212 is a nylon cable tie; nylon cable ties have good toughness and are used to seal the first opening of the first cavity. Similarly, in other embodiments, the second tying member 222 is a nylon cable tie to seal the second opening of the second cavity. In other embodiments, the third tying member 232 is a nylon cable tie to seal the third opening of the third cavity.

[0055] In one embodiment, the particle size of the sand is 3 mm to 5 mm, so that the sand can be well filled in the second waterproof bag 221 to ensure the filling density of the weighted sandbag 210 so that the buoyancy structure 10 can be vertically fixed in the swimming pool 22.

[0056] It should be noted that by setting the particle size of the sand to be 3 mm to 5 mm and the particle size of the first rubber magnetic bead 2331 to be 1 mm to 3 mm, since the particle size of the sand is 3 mm to 5 mm, it is ensured that the sand is filled in the second waterproof bag 221 to form a counterweight portion 213 with a relatively high filling density. In this way, when water enters the counterweight portion 213 at 24, the dense counterweight portion 213 can effectively slow down the phenomenon that water flows into the counterweight magnetic attraction bag 230 and causes the first magnetic attraction body 233 to rust. Further, in this application, by setting the particle size of the first rubber magnetic bead 2331 to be not greater than that of the sand, a first magnetic attraction body 233 with a higher filling density can be obtained, so as to reduce the flow rate of water in the first magnetic attraction body 233, thereby effectively preventing water from entering the interior of the first magnetic attraction body 233, slowing down the rusting speed of the first magnetic attraction body 233, further prolonging the service life of the first magnetic attraction body 233, and thus improving the service life of the buoyancy structure 10.

[0057] As Figure 3 , Figure 4 shown, in one of the embodiments, the first cloth body 110 includes a first plastic elastic layer 111, a first glue layer 112, and a first waterproof layer 113. The first plastic elastic layer 111 is adhesively connected to the first waterproof layer 113 through the first glue layer 112 to further improve the waterproof performance and wear resistance of the first cloth body 110. Similarly, in one of the embodiments, the second cloth body 120 includes a second plastic elastic layer 121, a second glue layer 122, and a second waterproof layer 123. The second plastic elastic layer 121 is adhesively connected to the second waterproof layer 123 through the second glue layer 122 to further improve the waterproof performance and wear resistance of the first cloth body 110.

[0058] In one of the embodiments, the thickness of the first plastic elastic layer 111 is 1.0 mm to 3.0 mm, so as to ensure that the thickness of the first plastic elastic layer 111 within the range of 1.0 mm to 3.0 mm can provide good waterproof performance and wear resistance, thereby prolonging the service life of the outer covering 100 assembly and also saving production costs. Similarly, in one of the embodiments, the thickness of the second plastic elastic layer 121 is 1.0 mm to 3.0 mm, so as to ensure that the thickness of the second plastic elastic layer 121 within the range of 1.0 mm to 3.0 mm can provide good waterproof performance and wear resistance, thereby prolonging the service life of the outer covering 100 assembly and also saving production costs.

[0059] In this embodiment, both the first plastic elastic layer 111 and the second plastic elastic layer 121 are TPE (Thermoplastic Elastomer) layers. Since the TPE layer has good wear resistance and waterproof performance, the first plastic elastic layer 111 and the second plastic elastic layer 121 can effectively block moisture from entering the counterweight assembly 200, thereby avoiding the phenomenon that bacteria are likely to grow in the counterweight part 213, the cotton wool part 223, and the first magnetic body 233. Also, because the outer covering assembly 100 has good wear resistance, the outer covering assembly 100 is not easily damaged during long-term use, extending the service life of the buoyancy structure 10.

[0060] As Figure 3 shown, in one embodiment, the counterweight assembly 200 further includes at least two partition sheets. Each of the partition sheets is used to divide the accommodation cavity into a first sub-cavity 141, a second sub-cavity 142, and a third sub-cavity 143. The first sub-cavity 141 is used to accommodate the counterweight sandbag 210, the second sub-cavity 142 is used to accommodate the counterweight cotton bag 220, and the third sub-cavity 143 is used to accommodate the counterweight magnetic bag 230 so that the counterweight sandbag 210 can be placed in the second sub-cavity 142, the counterweight cotton bag 220 can be placed in the first sub-cavity 141, and the counterweight magnetic bag 230 can be placed in the third sub-cavity 143 more quickly during production, thereby improving the production efficiency of the buoyancy structure 10.

[0061] Furthermore, each partition sheet can also effectively prevent the cross-transfer of moisture among the counterweight sandbag 210 in the first sub-cavity 141, the counterweight cotton bag 220 in the second sub-cavity 142, and the counterweight magnetic bag 230 in the third sub-cavity 143, ensuring the hygiene of the first sub-cavity 141, the second sub-cavity 142, and the third sub-cavity 143.

[0062] In this embodiment, the number of the partition sheets is two, namely the first partition sheet 310 and the second partition sheet 320. The first partition sheet 310 divides the accommodation cavity into the first sub-cavity 141 and the second sub-cavity 142, and the second partition sheet 320 divides the accommodation cavity into the first sub-cavity 141 and the third sub-cavity 143, so that the counterweight part 213, the cotton wool part 223, and the first magnetic body 233 can be respectively accommodated in the first sub-cavity 141, the second sub-cavity 142, and the third sub-cavity 143.

[0063] As Figure 3As shown, in this embodiment, the second sub-chamber 142, the first sub-chamber 141, and the third sub-chamber 143 are arranged in sequence along the extending direction of the buoyancy structure 10. It can be understood that by arranging the second sub-chamber 142, the first sub-chamber 141, and the third sub-chamber 143 in sequence along the extending direction of the buoyancy structure 10, it is ensured that the cotton wool part 223, the counterweight part 213, and the first magnetic attraction body 233 are arranged along the vertical direction of the buoyancy structure 10, so that the buoyancy structure 10 can be well positioned in the swimming pool 22, and the fixing effect of the buoyancy structure 10 can be better ensured.

[0064] In this embodiment, the volume ratio of the second sub-chamber 142, the first sub-chamber 141, and the third sub-chamber 143 is (1.5 - 2.5) : (5 - 7) : (0.5 - 1). It can be understood that by setting the volume ratio of the second sub-chamber 142, the first sub-chamber 141, and the third sub-chamber 143 to be (1.5 - 2.5) : (5 - 7) : (0.5 - 1), when the buoyancy structure 10 is placed in the water 24, the cotton wool part 223, the counterweight part 213, and the first magnetic attraction body 233 can achieve self-balancing in the water 24. At the same time, in cooperation with the use of the second magnetic attraction body 23, the resultant force of the buoyancy structure 10 and the second magnetic attraction body 23 is zero, so as to ensure that the buoyancy structure 10 can be better positioned in the water 24.

[0065] As Figure 5 shown, the present application further provides a water equipment 20, including the buoyancy structure 10 described in any of the above embodiments. It can be understood that the water equipment 20 further includes a fishing net assembly and a receiving member, so that children can pick up the buoyancy structure 10 through the fishing net assembly and place it in the receiving member, thereby further improving the fun of children playing in the water and enhancing the experience of children.

[0066] As Figure 5As shown, in one embodiment, the water device 20 further includes a swimming pool assembly 21. The swimming pool assembly 21 includes a swimming pool 22 and a plurality of second magnetic bodies 23. Each of the second magnetic bodies 23 is disposed at the bottom of the swimming pool 22, and each second magnetic body 23 is used to magnetically attract the first magnetic body 233. It can be understood that the swimming pool 22 is used to hold water 24. By arranging a plurality of second magnetic bodies 23 at the bottom of the swimming pool 22, when a child places the buoyancy structure 10 in the swimming pool 22 so that the counterweight portion 213 and the first magnetic body 233 can sink into the water 24, and at the same time the first magnetic body 233 can magnetically attract the corresponding second magnetic body 23 in the swimming pool 22, so as to improve the fixing property of the buoyancy structure 10 positioned in the water 24, ensuring that the child can quickly and accurately grab the buoyancy structure 10 in the water and avoiding the phenomenon of difficult grabbing. Further, since a plurality of second magnetic bodies 23 are arranged at the bottom of the swimming pool 22, the plurality of second magnetic bodies 23 can provide a plurality of positioning points at the bottom of the swimming pool 22, expanding the activity range for children to play.

[0067] As Figure 5 shown, in one embodiment, each of the second magnetic bodies 23 is evenly distributed at the bottom of the swimming pool 22 to ensure that the second magnetic bodies 23 are more comprehensively distributed at the bottom of the swimming pool 22, ensuring that children can play at various positions in the swimming pool 22.

[0068] As Figure 6 shown, in this embodiment, the second magnetic body 23 includes a magnetic bead body and a second rubber layer 26. The second rubber layer 26 is coated on the surface of the magnetic bead body. It can be understood that since the surface of the magnetic bead body is coated with the second rubber layer 26, water 24 is prevented from entering the magnetic bead body, avoiding the magnetic bead body from being easily rusted and reducing the magnetism of the magnetic bead body. In this embodiment, the second rubber layer 26 is a silica gel layer. Due to the good waterproof property of the silica gel layer, the phenomenon that the second rubber magnetic bead 27 is easily rusted can be effectively avoided. In addition, due to the good softness of the silica gel layer, when a child plays in the water, the soles of the feet can directly contact the second rubber layer 26, which can play a certain massage role on the soles of the feet, enabling the soles of the child's feet to be relaxed to a certain extent and promoting the healthy growth of the child.

[0069] As Figure 6 shown, in one embodiment, the magnetic bead body includes a plurality of second rubber magnetic beads 27. It can be understood that the second rubber layer 26 forms a receiving cavity, and each of the second rubber magnetic beads 27 is located in the receiving cavity. On the one hand, each of the second rubber magnetic beads 27 magnetically attracts the first magnetic body 233 of the buoyancy structure 10, thereby improving the magnetic attraction between the second magnetic body 23 and the first magnetic body 233. On the other hand, it improves the contact massage between the plurality of rubber magnetic beads and the soles of the feet to better improve the massage effect on the soles of the feet.

[0070] As Figure 6 shown, in one embodiment, the surface of the second rubber magnetic bead 27 is coated with a third rubber layer 28 to prevent water from entering the second rubber magnetic bead 27, so as to prevent the metal material of the second rubber magnetic bead 27 from rusting easily, which may lead to a decrease in the magnetism of the second rubber magnetic bead 27. In this embodiment, the third rubber layer 28 is a silica gel layer. Since the silica gel layer has good waterproof performance, it can effectively prevent the second rubber magnetic bead 27 from rusting easily. In addition, due to the good softness of the silica gel layer and the combined use of the second rubber layer 26, a double-layer silica gel layer can be formed on the surface of the second magnetic attraction body 23, further improving the waterproof performance. At the same time, the double-layer silica gel layer can also further improve the softness of the second magnetic attraction body 23, thereby further enhancing the massage effect of the second magnetic attraction body 23 on the sole of the foot.

[0071] As Figure 5 shown, in one embodiment, a plurality of receiving grooves are formed in the bottom of the swimming pool 22, and each of the second magnetic attraction bodies 23 protrudes from the corresponding receiving groove. It can be understood that since a plurality of receiving grooves are formed in the bottom of the swimming pool 22, the plurality of receiving grooves can provide good positioning for the plurality of second magnetic attraction bodies 23, so that the user can quickly install and fix the plurality of second magnetic attraction bodies 23 in the plurality of receiving grooves to achieve the rapid assembly of the plurality of second magnetic attraction bodies 23.

[0072] In addition, since the second magnetic attraction body 23 protrudes from the corresponding receiving groove, on the one hand, the contact area between the second magnetic attraction body 23 and the water 24 is reduced, and the corrosion of the second rubber layer 26 is reduced, so as to extend the service life of the second magnetic attraction body 23; on the other hand, the second magnetic attraction body 23 can provide a massage contact point for the foot, so that the sole of the child's foot can better contact the protruding second magnetic attraction body 23 to ensure good massage on the sole of the foot. Further, since the second magnetic attraction body 23 is a sphere, the contact between the protruding second magnetic attraction body 23 and the sole of the foot is an arc contact, so that the arc contact can provide better massage for the sole of the foot. <�

[0073] Furthermore, since a plurality of second rubber magnetic beads 27 are provided in the second magnetic attraction body 23, it is ensured that the plurality of second rubber magnetic beads 27 are magnetically attracted to the buoyancy structure 10, and the contact massage points between the sole of the foot and the plurality of rubber magnetic beads are also increased, so as to simultaneously massage different positions of the sole of the foot and achieve a better massage effect on the sole of the foot.

[0074] Compared with the prior art, the present invention has at least the following advantages:

[0075] 1. For the above buoyancy structure 10, the first fabric body 110 and the second fabric body 120 are sewn together by a sewing thread 130 to form an outer covering assembly 100 of a toy prototype required for production, and a receiving cavity is formed on the outer covering assembly 100. Since the density of the counterweight sandbag 210 and the counterweight magnetic bag 230 is greater than that of water 24, and the density of the counterweight cotton bag 220 is less than that of water 24, when the buoyancy structure 10 is placed in water 24, the counterweight sandbag 210 and the counterweight magnetic bag 230 will sink into the water 24, while the counterweight cotton bag 220 will float on the water surface of the water 24, so as to reduce the movement of the buoyancy structure 10 caused by the fluctuation of the water 24, that is, the buoyancy structure 10 requires a relatively large fluctuation of the water 24 to cause the buoyancy structure 10 to move, thereby improving the fixation of the buoyancy toy in the water 24. Further, since the counterweight magnetic bag 230 is provided with a first magnetic body 233, when the buoyancy structure 10 is placed in a swimming pool 22 provided with a second magnetic body 23, the first magnetic body 233 of the counterweight magnetic bag 230 can be magnetically attracted to the second magnetic body 23 of the swimming pool 22, further improving the fixation of the buoyancy structure 10 in the water 24 and further improving the fixation of the buoyancy structure 10 in the water 24 to ensure that children can quickly and accurately grab the buoyancy structure 10 in the water 24 to avoid the phenomenon of difficult grabbing. In addition, since the counterweight cotton bag 220, the counterweight sandbag 210 and the counterweight magnetic bag 230 are arranged in the outer covering assembly 100, the buoyancy structure 10 realizes self-balancing in the water 24 through the counterweight cotton bag 220, the counterweight sandbag 210 and the counterweight magnetic bag 230, which is not only simple in structure but also low in cost.

[0076] 2. For the above buoyancy structure 10, since the outer covering component 100 houses the counterweight sandbag 210, the counterweight cotton bag 220, and the first magnetic body 233 in the accommodation cavity, the outer covering component 100 can effectively prevent moisture from entering the interior, thereby reducing the phenomenon that bacteria are likely to grow inside the buoyancy structure 10. Also, since the counterweight sandbag 210 includes a first waterproof bag 211, a counterweight portion 213, and a first tying member 212, the counterweight portion 213 can be sealed inside the first waterproof bag 211. The counterweight cotton bag 220 includes a second waterproof bag 221, a second tying member 222, and a cotton wool portion 223, so that the cotton wool portion 223 can be sealed inside the second waterproof bag 221. The counterweight magnetic bag 230 includes a third waterproof bag 231, a third tying member 232, and the first magnetic body 233, so that the first magnetic body 233 can be sealed inside the third waterproof bag 231, further preventing moisture from entering the counterweight portion 213, the cotton wool portion 223, and the first magnetic body 233, to ensure that the counterweight portion 213, the cotton wool portion 223, and the first magnetic body 233 can be maintained in a relatively dry environment. In this way, on the one hand, it ensures that the buoyancy structure 10 of the counterweight assembly 200 can provide a relatively constant buoyancy, so as to ensure that the buoyancy structure 10 still maintains a relatively stable buoyancy during long-term use, and to ensure that the buoyancy structure 10 can float in the water 24 in a self-balanced manner. On the other hand, it avoids the growth of bacteria in the counterweight assembly 200 caused by moisture entering the counterweight portion 213, the cotton wool portion 223, and the first magnetic body 233, thereby improving the hygiene of the buoyancy structure 10.

[0077] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
