Detailed Description
The present invention will be described more fully hereinafter in order to facilitate an understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1 to 15, a toy water ball according to a first embodiment of the present invention is used for game play and is thrown as a prop. The toy water ball has a closed state (shown in figure 1) and an expanded state (shown in figure 2), and after the toy water ball is put into water and filled with water, the toy water ball forms a closed water carrying cavity after the combined state is restored. When the toy water ball is hit on a person or on the ground or a hard object in the game process, the toy water ball is pressed and split into an unfolding state, and the loaded water is splashed out to achieve the purpose of the game.
Referring specifically to fig. 1-15, a first embodiment of the present invention provides a toy water ball 10 comprising a pair of petals 12 and a connecting portion 14 connecting the petals 12, each petal 12 comprising a body (also called a water bladder or water bag) 16 and an annular rim portion 18 extending laterally inwardly (i.e., away from the body's peripheral edge) from the body's 16 peripheral edge, i.e., the annular rim portion 18 extends inwardly from the body's 16 peripheral edge beyond the body's 16 inner surface, each annular rim portion 18 having a magnetic attraction assembly 30 mounted thereon, the connecting portion 14 being bendable between an extended state and a bent state so that the petals 12 can be switched between a closed state and an open state.
When the two valve bodies 12 are in a closed state, the two valve bodies 12 jointly enclose into a water carrying cavity 22, and the magnetic attraction assemblies 30 on the two valve bodies 12 attract each other so that the annular edge parts 18 of the two valve bodies 12 are tightly attached due to deformation, thereby forming a water blocking layer, and the water blocking layer seals the water carrying cavity 22; the annular edge 18 extends transversely into the water carrying cavity 22, and water in the water carrying cavity 22 at two sides of the annular edge 18 in the thickness direction applies pressure to the annular edge 18 from two opposite directions, so that the annular edge 18 of the two flaps 12 is further tightly attached, and sealing and waterproof effects are improved.
When in use, the two valve bodies 12 are opened and placed in water to be filled with water, and then the two valve bodies 12 are closed and sealed and matched by utilizing the magnetic attraction assembly 30 on the annular edge part 18, so that the water in the water carrying cavity 22 is prevented from flowing out in advance; when the toy water ball 10 in the closed state is crashed on a human body, the toy water ball 10 deforms and the magnetic attraction assemblies 30 on the two valve bodies 12 are separated from the magnetic attraction cooperation under the action of internal water pressure, so that the two valve bodies 12 are separated, and water in the toy water ball 10 can be splashed out, thereby forming the entertainment effect. The toy water ball 10 can be repeatedly switched between a closed state and an open state by utilizing the magnetic attraction matching of the magnetic attraction component 30, so that the toy water ball 10 can be repeatedly used, and the toy water ball is environment-friendly and clean; in addition, the toy water ball 10 can be used in more occasions without a specific pressure water source, and has stronger applicability.
The specific shape of the toy water ball 10 is not limited, and may be, for example, a sphere, an ellipse, an irregular sphere, a cartoon shape, or the like, as long as it can carry water in a closed state. In this embodiment, both petals 12 are in the shape of a semi-spherical shell, the bodies 16 of both petals 12 are symmetrical about the midline of the connecting portion 14, the annular rim portions 18 of both petals 12 extend radially inward, the outer diameters of the annular rim portions 18 of both petals 12 are substantially equal, and when both petals 12 are closed, a spherical toy water ball 10 is formed.
As shown in fig. 3, 11 and 13, each annular rim portion 18 is an elastomer, resilient and deformable, and when the valve body 12 is in the closed position, the annular rim portion 18 of the valve body 12 deforms to conform closely under the magnetic attraction generated by the magnetic attraction assembly 30. The annular edge 18 can be deformed, when the two petals 12 approach each other under the action of the magnetic attraction component 30, the annular edge 18 can be deformed, and after the annular edge 18 is deformed, elastic restoring force can be generated, so that the two annular edge 18 are tightly attached together, and a good sealing effect is formed.
Specifically, when the flap body 12 is switched to the closed state by the magnetic attraction force generated by the magnetic attraction assembly 30, the two annular edge portions 18 interfere in the thickness direction thereof, so that deformation occurs in the thickness direction, so that the two annular edge portions 18 are closely fitted.
The specific material of the annular edge portion 18 is not limited as long as it has elastic properties and is deformable, for example, a silica gel.
The material of the body 16 may be the same as or different from that of the annular edge 18, and for example, the body 16 may be made of a thin and soft sheet such as a silicone body. When both the body 16 and the annular rim portion 18 are colloidal silica, the body 16 may be integrally or partially formed with the annular rim portion 18.
In this embodiment, each annular rim 18 has an abutment surface 24 for abutment with another annular rim 18, i.e. the abutment surfaces 24 of the two annular rims 18 abut each other in the closed position of the toy water ball 10. The joint surface 24 of at least one annular edge part 18 is a concave surface in a natural state, the concave surface deforms towards the other annular edge part 18 under the action of magnetic attraction generated by the magnetic attraction assembly 30, and the two joint surfaces 24 are tightly jointed together under the action of the magnetic attraction assembly 30, so that a sealing effect is achieved, and water leakage is prevented.
In this embodiment, at least one annular edge 18 includes an annular main body 26 connected to the corresponding body 16 and a flange 28 extending obliquely inward from the circumferential inner side of the annular main body 26, the flange 28 being located laterally inward of the corresponding magnetic assembly 30 and being capable of deforming, i.e., the flange 28 being located laterally inward of the magnetic assembly 30 in the lateral direction of the body 16 (as shown in fig. 6), the outer surface of the annular main body 26 and the outer surface of the flange 28 together forming the abutment surface 24, i.e., the concave surface, of the annular edge 18, and the flange 28 abutting, i.e., interfering with and deforming, the other annular edge 18 under the magnetic attraction generated by the magnetic assembly 30. Specifically, in this embodiment, one of the annular edge portions 18 includes an annular main body 26 and a flange 28, the annular main body 26 and the flange 28 are disposed at an included angle, and the included angle between the annular main body 26 and the flange 28 is greater than 90 ° and less than 180 °, that is, the included angle between the concave straight line segment and the inclined segment is greater than 90 ° and less than 180 °, the abutting surface 24 of the other annular edge portion 18 is a plane in a natural state, when the two flaps 12 are close to each other under the action of the magnetic attraction assembly 30, the flange 28 of the annular edge portion 18 abuts against the other annular edge portion 18 and deforms under the action of the magnetic attraction force generated by the magnetic attraction assembly 30, so that the flange 28 is changed from an inclined state to a flat state, and finally, the surface of the flange 28 is coplanar with the surface of the annular main body 26, so as to form a complete plane, and is tightly abutted against the abutting surface 24 of the other annular edge portion 18, and the flange 28 abuts against the other annular edge portion 18 under the action of its own elasticity, so as to achieve the effect of enhancing the tightness (as shown in fig. 11). The thickness of the flange 28 gradually decreases along the direction away from the body, the thickness of the flange 28 is smaller than the thickness of the annular main body 26, the preferred thickness range of the flange 28 is 0.3-0.43 mm, and the thickness of the annular main body 26 is the thickness of the annular edge 18.
Specifically, in this embodiment, the abutment surfaces 24 of the two annular edge portions 18 are concave in nature, that is, each annular edge portion 18 includes an annular main body 26 and a flange 28, when the two petals 12 are brought close to each other by the magnetic assembly 30, the two flanges 28 abut against each other and deform by the magnetic assembly 30, and the two flanges 28 are transformed from an inclined state to a flat state, and finally the surfaces of the flanges 28 are coplanar with the surfaces of the corresponding annular main bodies 26 to form a complete plane and closely fit. The natural state refers to a state in which the two annular edge portions 18 are not under an external force, for example, a state in which the two magnetic attraction members 30 are not magnetically attracted to each other. When the magnetic attraction components 30 on the two valve bodies 12 attract each other, the magnetic attraction force generated by the magnetic attraction components 30 pulls the two annular edge parts 18 towards each other, so that the concave surface deforms, the two joint surfaces are tightly jointed together to achieve a sealing effect, the situation that the two annular edge parts 18 leak water due to the fact that the two annular edge parts cannot be tightly jointed due to machining or assembly errors can be prevented, the requirement on precision is reduced, and the production difficulty is further reduced.
The specific manner of forming the concave surface is not limited, and for example, a curved surface may be formed by recessing the middle portion of the bonding surface 24 of the annular edge portion 18 or the entire bonding surface 24, or may be formed by enclosing a plurality of non-coplanar planes or curved surfaces.
As shown in fig. 1 to 3, in the present embodiment, the connecting portion 14 is made of an elastic material and is bendable between an expanded state and a bent state, i.e., the connecting portion 14 is capable of deforming and forming different bending curvatures, so that the valve body 12 can be switched between an open state and a closed state. The two valve bodies 12 are connected together by the connecting part 14, when the toy water ball 10 is hit on a human body to cause the two valve bodies 12 to be separated, the two valve bodies 12 are still connected together by the connecting part 14, so that the valve bodies 12 can be prevented from being lost, and the toy water ball is convenient for a user to use.
It will be appreciated that the two ends of the connecting portion 14 may be connected to the two bodies 16, respectively, or may be connected to the two annular edge portions 18, respectively, or that one end of the connecting portion 14 is connected to the body 16 of one of the valve bodies 12, and the other end is connected to the annular edge portion 18 of the other valve body 12. In the present embodiment, both ends of the connecting portion 14 are fixedly connected with the two annular edge portions 18, respectively.
When the pair of petals 12 are in the closed state, the connecting portions 14 are bent into a C-shaped or U-shaped structure and protrude from the outer surfaces of the petals 12. In this embodiment, the connecting portion 14 is a flexible sheet, and when the toy water ball 10 is in a closed state, the connecting portion 14 is bent to form a C-shape or a U-shape.
As shown in fig. 3-8, each valve body 12 has a magnetic assembly 30 thereon. Each magnetic component 30 comprises a plurality of magnetic pieces 31 and a fixing component 40, and the fixing component 40 comprises a fixing shell 41 fixedly connected to the surface of each magnetic piece 31 and a connecting strip 42 connected with the fixing shell 41. In this embodiment, the fixing member 40 is a plastic body.
The fixing case 41 wraps the outer surface of the corresponding magnetic attraction member 31. The term "wrapping" as used herein means that the fixing case 41 is tightly attached to most of the surface of the magnetic attraction member 31 to ensure that the magnetic attraction member 31 does not separate from the fixing case 41, and not necessarily all of the surface of the magnetic attraction member 31 is closed. In this embodiment, the fixing case 41 is provided with at least one clamping groove 410 for clamping the annular edge 18. In the present embodiment, the number of the clamping grooves 410 is four, and each clamping groove 410 is located at four corners of a surface of the fixing case 41 facing away from the annular edge portion 18 (i.e. a surface facing the body 16). The clamping groove 410 penetrates through the fixing case 41 to correspondingly expose the magnetic attraction piece 31 inside the fixing case 41. It will be appreciated that the slot 410 may be other shapes, such as a bar-shaped slot around the surface of the fixed housing 41, etc.
The annular rim 18 has a mounting surface 29 facing the body 16 (the mounting surface 29 and the abutment surface 24 are located on opposite sides of the annular rim 18). Specifically, the mounting face 29 is located on the annular main body 26 and faces the body 16. The mounting surface 29 of the annular edge portion 18 is provided with mounting grooves 291 and connecting grooves 292 communicating with the adjacent mounting grooves 291, the mounting grooves 291 are used for accommodating and fixing the corresponding fixing housings 41, and the connecting grooves 292 are used for accommodating and fixing the corresponding connecting bars 42. In the present embodiment, the shape of the mounting groove 291 matches the half of the fixing case 41 (e.g., the lower half in fig. 4), and the shape of the connection groove 292 matches the half of the corresponding connection bar 42. The annular edge 18 extends at least one fastening portion 293 corresponding to the periphery of the mounting groove 291, and the fastening portion 293 is correspondingly fastened on the fastening groove 410 of the fixing housing 41, so as to increase the firmness of the annular edge 18 and the magnetic assembly 30. In this embodiment, the fastening portion 293 is fastened to the fastening groove 410 of the fixing case 41 to cover the fastening groove 410, so that the annular edge 18 and the fixing case 41 cooperate to completely wrap the magnetic attraction member 31.
In addition, the fixing housings 41 are provided with insertion holes 415 (as shown in fig. 3) on one surface facing the annular edge 18, and the annular edge 18 is provided with protruding posts 294 (as shown in fig. 5) protruding above the mounting surface 29, and the protruding posts 294 are fitted into the corresponding insertion holes 415, thereby increasing the firmness of the fixing housings 41 and the annular edge 18.
It will be appreciated that in other embodiments, the mounting housing 41 may be frame-like or otherwise configured to provide a secure connection with the magnetic attraction member 31.
In this embodiment, adjacent fixing shells 41 are all connected together by a connecting strip 42, so that the entire fixing assembly 40 is arranged in a closed ring shape. In other words, the fixing case 41 and the connecting strip 42 are sequentially connected end to form a ring shape. In other embodiments, a certain section of the connecting bar 42 may be omitted, i.e. the fixing assembly 40 may not be a closed loop, but it must be ensured that at least one end of each fixing shell 41 is connected to a corresponding adjacent fixing shell 41 by the connecting bar 42. The purpose of this arrangement is to avoid the occurrence of a single magnetic attraction piece 31 and a corresponding fixing case 41 falling off, and to prevent the occurrence of misfeeding by a child. The magnetic attraction pieces 31 are connected with at least one adjacent magnetic attraction piece 31 through the fixing shell 41 and the connecting strip 42, so that the firm strength is greatly improved, and meanwhile, the magnetic attraction assembly 30 is prevented from being eaten by children due to the fact that the size is too small.
In addition, by arranging the fixing shell 41 and the connecting strip 42, the connecting area of the magnetic assembly 30, the annular edge 18 and the body 16 can be greatly increased; the magnetic assembly 30 of the present embodiment increases the area of engagement with the annular rim 18 to improve security, greatly reducing the risk of the magnetic assembly 30 falling off the valve body 12 and improving safety over prior art designs in which only a single independent magnet is attached to the rim.
In the present embodiment, each magnetic attraction member 31 is assembled with the fixing member 40 by integral injection molding. Specifically, the magnetic component 31 is placed in a corresponding mold, then hot-melt plastic is injected to surround the magnetic component 31, and the magnetic component 30 is formed by cooling and then taking out the magnetic component, i.e. the magnetic component comprises the magnetic component 31 and the fixing component 40, wherein the fixing component 40 has the shape structure (comprising the fixing shell 41 and the connecting strip 42) set by the mold, and at this time, the magnetic component 30 shown in fig. 3 and fig. 4 is formed. Then, after the magnetic assembly 30 is put into a second mold (an adhesive layer may be provided on the surface of the fixing case 41), the annular edge portion 18 and the connection portion 14 are formed by hot pressing or injection molding; the mounting surface 29 of the annular edge 18 is correspondingly matched with the magnetic attraction assembly 30 to form the mounting groove 291 and the connecting groove 292, and a fastening portion 293 is formed to be fastened to the fastening groove 410 of the fixing case 41, and the structure after this is shown in fig. 6. Finally, the assembled magnetic assembly 30, the annular edge 18 and the connecting portion 14 are placed into a third mold (an adhesive layer can be arranged on the surface of the fixing shell 41), and then the body 16 is integrally formed by injection molding or hot pressing, so that the whole toy water ball is manufactured.
As shown in fig. 3, a surface of each body 16 facing the magnetic component 30 is provided with a corresponding first groove 161 and a second groove 162 communicating with the first groove 161, wherein the first groove 161 is used for accommodating and fixing the fixing shell 41 of the magnetic component 30, and the second groove 162 is used for accommodating and fixing the connecting strip 42 (accommodating the fixing shell 41 and the connecting strip 42, such as a lower half in fig. 3). Specifically, each of the first grooves 161 of the body 16 accommodates and fixes the corresponding fixing case 41 together in cooperation with the mounting groove 291 of the annular edge portion 18, and the connecting grooves 292 accommodate and fix the corresponding connecting bar 42 together in cooperation with the connecting grooves 292.
By the arrangement, the connection between the magnetic attraction piece 31 and the annular edge part 18 is firmer, and even if a part of the magnetic attraction piece 31 and the annular edge part 18 is loose, the magnetic attraction piece 31 cannot fall off independently and is taken by mistaking due to the existence of the fixing shell 41 and the connecting strip 42. The number of the connection bars 42 is determined according to the size of the fixing shells 41 and the distance between the adjacent fixing shells 41 (i.e. the size of the magnetic attraction pieces 31 and the distance between the adjacent magnetic attraction pieces 31), if the size of the two adjacent fixing shells 41 and the connection bars 42 therebetween is large enough, the two adjacent fixing shells 41 cannot be eaten by children, i.e. it is only necessary to ensure that each magnetic attraction piece 31 is wrapped by the corresponding fixing shell 41, and at least one end of each fixing shell 41 is connected with the corresponding adjacent fixing shell 41 through the connection bars 42. Not necessarily all of the adjacent fixing housings 41 are connected by the connection bars 42.
The specific material of the fixing component 40 is not limited, as long as it can be firmly combined with the magnetic attraction piece 31. Preferably, the fixing component 40 is made of plastic, so that the fixing component and the magnetic attraction piece 31 can be integrally injection molded, thereby ensuring firm combination with the magnetic attraction piece 31 and simplifying the manufacturing process. The plastic material of the fixing component 40 may be nylon (also called polyamide, PA), polypropylene (PP), polyethylene (PE); wherein, nylon material is better.
It will be appreciated that as shown in fig. 16-18, the securing assembly 40 in other embodiments may be provided in a non-closed loop arrangement, i.e., with each securing shell 41 having at least one connecting strip 42 attached thereto, with portions of the connecting strips 42 omitted; the attachment surface 29 of the annular rim 18 is also omitted with respect to the attachment groove 292, and the body 16 is omitted with respect to the second recess 162. Although part of the connection bars 42 are omitted, it is only necessary to ensure that each of the fixing cases 41 is connected to at least one connection bar 42, so that the fixing assembly 40 can be ensured to have a sufficient size and not be swallowed by a child even if it is detached from the toy water ball 10. As shown in fig. 16 and 17, two ends of each connecting strip 42 are connected to the corresponding adjacent fixing case 41. As shown in fig. 18, each fixing case 41 is connected to only one connecting bar 42, and only one end of each connecting bar 42 is connected to one fixing case 41 while the other end is suspended.
As shown in fig. 6, 7, 14 and 15, the connecting strip 42 in the present embodiment is provided in a wavy curved configuration, that is, a curved shape in which the circle H of the annular main body 26 corresponding to the two adjacent fixing cases 41 is left and right waved about the center (for example, the dashed circle in fig. 7). Specifically, each of the connecting strips 42 includes a plurality of folded line segments extending integrally from the corresponding fixing case 41 to the adjacent fixing case 41. The reason for this is that in order to make the connecting strip 42 have a certain deformation (the length of the connecting strip 42 changes, so that the closed loop fixing component 40 can be enlarged or reduced in the radial direction), since after the magnetic component 30, the annular edge 18 and the connecting portion 14 are integrally put into the third mold to form the body 16 connecting the magnetic component 30 and the annular edge 18, when the toy water ball 10 is to be taken out from the mold, the inner diameter of the annular edge 18 needs to be expanded, and the annular edge 18 itself has elasticity, but the fixing component 40 has a small deformation force due to the plastic body, and a certain expansion and shrinkage property is required to be achieved by arranging the connecting strip 42 in a wavy shape, so that the process of taking out from the mold is realized. Of course, if the fixing member 40 is not continuously formed as shown in fig. 16 to 18, and the connecting bar 42 is removed from the mold without being deformed, the connecting bar 42 may directly take an arc-like shape.
In this embodiment, the magnetic attraction member 31 is a magnet. The magnet is a permanent magnet. The magnetic flux density of the magnets is too low, attractive force between the magnets is too small, the water ball is easy to open in advance before reaching a target, water leaks in the air, if the number of the magnets is increased, the distance between the magnets is reduced (the size of the toy water ball for children cannot be too large, otherwise the children cannot hold the toy water ball, the overall size of the water ball is limited), and the deformation of the joint surface and the sealing effect of the water ball are influenced; the magnetic flux density is too large, attractive force between the magnets is too large, the water ball is not easy to open, the water ball is painful when played on a child, and the child is easy to be injured. The inventors of the present application have made diligent efforts to find a preferable magnetic flux density range, namely, when the magnetic flux density at the center position of the bonding surface facing the magnet is preferably 130MT to 260MT (millitesla), while considering both the deformability of the edge portion and the magnetic attraction force between the bonding surfaces (which cannot be too large and too small).
The number of the magnetic attraction pieces 31 on each annular edge portion 18 is not limited, and is only two or more. In this embodiment, a plurality of magnetic attraction pieces 31 are disposed on each annular edge 18, and the magnetic attraction pieces 31 on two annular edge 18 are the same in number and correspond to each other, and the plurality of magnetic attraction pieces 31 on the corresponding annular edge 18 are uniformly arranged at intervals along the circumferential direction of the annular edge 18.
The invention also provides a preparation method of the toy water ball, which is used for preparing the toy water ball and comprises the following steps:
step 1: putting a magnetic attraction piece into a first die, injecting hot-melt plastic to surround the magnetic attraction piece, cooling, and taking out to form a magnetic attraction assembly, wherein the magnetic attraction assembly comprises a fixing assembly and at least two magnetic attraction pieces, the fixing assembly comprises at least two fixing shells and at least two connecting strips, each fixing shell is respectively connected and fixed on the surface of the corresponding magnetic attraction piece, and at least one end of each fixing shell is connected with one connecting strip;
step 2: placing the magnetic component into a second die, and forming an annular edge part and a connecting part in a hot pressing or injection molding mode; the annular edge part is correspondingly matched with the magnetic component to form a mounting groove and a connecting groove;
step 3: and (3) placing the magnetic assembly, the annular edge part and the connecting part assembled in the step (2) into a third die, and integrally forming the body by injection molding or hot pressing.
In the step 2, before the magnetic component is placed in the second mold, an adhesive layer is coated on the surface of the fixing shell.
Wherein, the fixed shell in the step 1 is provided with a clamping groove; in the step 2, the annular edge part forms a clamping part clamped on the clamping groove of the fixing shell.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
