Technical Field

[0001] This utility model belongs to the technical field of infant and toddler educational toys, specifically relating to an infant and toddler fun and educational toddler kit. Background Technology

[0002] Children receive early childhood education through interaction with their parents or early childhood educators, especially during infancy (children aged 1 to 3 years). The development of children's cognitive and logical systems is the core of early childhood education during this period, which determines children's future communication skills and education.

[0003] As an important tool for interaction, educational toys can play a certain auxiliary role in building the above-mentioned system. Appropriate educational toys can guide parents or early childhood educators to train children according to certain rules, such as training in color or direction judgment, classification logic, etc.

[0004] However, most existing early childhood education toys on the market adopt a flat design, have limited functionality, and lack visual appeal. After a certain number of training sessions, children's interest in these toys decreases significantly, ultimately affecting their educational effectiveness. Conversely, toys with a better user experience often resemble toys more than educational tools, diminishing their demonstrative and educational function. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fun educational toy box for infants and toddlers. By catching and marking fish in water and placing them in classification boxes according to their color, current condition, and other characteristics, the toy enhances the fun of early childhood education. It also has the function of color blindness screening and health care, while training infants' attention and patience to achieve better educational results.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution: This utility model provides a fun and educational toy box for infants and toddlers, including a box assembly, a marked fish, a label board, and a catching tool; The box assembly includes a box body support, an interactive basin, and a sorting frame. The box body support has a first chamber and a second chamber on its top surface and a side surface, respectively.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Unless otherwise defined, 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 pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Example 1: Please see Figures 1-3 This embodiment provides an infant and toddler fun and educational toy box 100 for early childhood education in areas such as color, shape, direction, and logic. It includes a box assembly 1, marker fish 2, label board 3, and catching tools 4. Specifically, the box assembly 1 includes a box support 11, an interactive basin 12, and a sorting box 13. The box support 11 has a first chamber 111 and a second chamber 112 on its top and one side surfaces, respectively. The interactive basin 12 is located in the first chamber 111, and the sorting box 13 is retractably located in the second chamber 112. The box assembly 1, as the main carrier of the infant and toddler fun and educational toy box 100, combines interactive, guiding, and storage functions. The interactive basin 12 is a fun interactive space, the sorting box 13 is a space for educational interaction and guidance, and placing all the marker fish 2 into the sorting box 13 and then pushing it into the box support 11 serves a storage function, making the structure compact and simple.

[0037] More specifically, the tagged fish 2 includes a body 21, and the surface of the body 21 has features of at least color, shape, and texture. A label plate 3 is printed with prompts matching the features of the body 21. Water is contained in the interactive basin 12, the tagged fish 2 is placed in the interactive basin 12, and the tagged fish 2 is removed from the interactive basin 12 using a catching tool 4. The sorting box 13 has multiple sorting compartments 131, and the label plate 3 is placed at the bottom of the sorting compartments 131. Based on the features of the surface of the body 21, the tagged fish 2 are sorted and placed in the sorting compartments 131.

[0038] In visual cognition and recognition training, the marker fish 2 can be drawn in different colors, while the label board 3 is printed with colors that match the marker fish 2. Color matching trains infants' color recognition. Before use, all marker fish 2 and label boards 3 need to be removed. Then, pour a certain amount of water into the interactive basin 12, or the interactive basin 12 can be detached from the box support 11 and water can be added separately. Then, pour some or all of the marker fish 2 into the interactive basin 12. The teacher or parent places the label boards 3 in the sorting compartments 131 in the desired order or randomly, and the infant can then begin learning and training.

[0039] Infants and toddlers hold the catching tool 4 and use it to grab the marked fish 2 in the interactive basin 12. After grabbing the fish, they place it into the corresponding sorting grid 131 according to its characteristics, thus completing a color discrimination training session. During the training, the teacher or parent only needs to observe the infant's behavior from the side, and then interact with and provide prompts when judging the result.

[0040] By first catching three-dimensional marked fish 2 in the water, and then classifying the marked fish 2 according to characteristic prompts, this process offers a better visual experience and is more engaging compared to existing early childhood education toys. Furthermore, compared to existing early childhood toys, its guiding and training functions are more prominent, ensuring the educational purpose of the toy is achieved. In addition, regarding infant and toddler health care, it has a function for screening for color blindness in infants and toddlers. For example, in the red-green color blindness test, red and green marked fish 2 and label boards 3 are used to test infants and toddlers, and the degree of color blindness is determined based on the number of tests and the accuracy rate.

[0041] Of course, the distinguishing features on the fish marker 2 and label plate 3 are not limited to color; features such as directional arrows can also be drawn on label plate 3. Figure 4 As shown, infants and toddlers can use the directional arrows to place the marker fish 2, thus training their recognition of "up, down, left, and right" directions. Alternatively, the marker fish 2 can be made in different shapes, such as triangles, circles, and trapezoids, with corresponding shape features drawn on the label board 3. Infants and toddlers can then sort and place the marker fish according to color and shape. Or, as... Figure 5 As shown, label panel 3 incorporates more feature classification methods. However, due to the large number of trainable features, they will not be listed here.

[0042] The three-dimensional tagged fish 2 is placed in the water, and its position changes with each attempt by the infant to catch it. Furthermore, since infants are accustomed to grasping objects with their hands, requiring them to use a catching tool 4 increases the difficulty. This method encourages infants to concentrate and be more patient when catching the tagged fish 2, thus helping them develop these skills. Attention and patience are essential abilities for future learning; training them in infancy can reduce stress for children later in their studies.

[0043] Considering that infants and young children do not have a concept of hygiene, they may easily put the marked fish 2 into their mouths or eat it directly after handling it. Therefore, the water in the interactive basin 12 should be boiled water that is safe to drink or purified water.

[0044] Please continue reading. Figures 1-3In this embodiment, to improve the visibility of the interactive basin 12, the interactive basin 12 should be a transparent basin, for example, made of transparent PP plastic (polypropylene plastic), to improve the aesthetics and visibility of the interactive basin 12. To further enhance visibility and provide infants with more viewing angles, a side window 113 is provided on the side of the box support 11 where the second chamber 112 is located, and the side window 113 is connected to the first chamber 111. The transparent interactive basin 12 and the side window 113 provide infants with more observation areas, facilitating their observation and catching. Furthermore, because the transparent interactive basin 12 and water cause some refraction of the marked fish 2, it provides infants with different visual experiences, increasing the visual depth and fun of the educational toy compared to existing conventional fish-catching (or fishing) toys.

[0045] In a further embodiment, the bottom of the side window 113 is connected to the bottom surface of the first chamber 111, forming a whole, providing the side window 113 with a larger and more comprehensive viewing angle. However, at the same time, the length of the side window 113 should be less than the length of the interactive basin 12 in that side direction. This makes it difficult for the interactive basin 12 to be pulled out from the side window 113 direction, preventing infants and young children from pulling the interactive basin 12 from the side window 113 direction, causing the interactive basin 12 to tip over outwards.

[0046] In this embodiment, please refer to Figure 6 As shown, the tagged fish 2 also includes a counterweight 22 disposed inside the main body 21, with the counterweight 22 positioned at the center of gravity of the main body 21. By adjusting the weight of the counterweight 22, the tagged fish 2 can obtain different gravities, and these different gravities will affect the actual position of the tagged fish 2 in the water. This allows different tagged fish 2 to be positioned at different depths in the water, increasing the visual effect of the tagged fish 2 in the interactive basin 12. During production, the main body 21 of the tagged fish 2 is usually made of plastic, and the counterweight 22 can be fixed in a mold or set in other ways. In this embodiment, the counterweight 22 is a metal part that can be attracted by a magnet, such as an iron block. Using a metal part that can be attracted by a magnet is beneficial for increasing the playability of the tagged fish 2 later, for example, by setting a magnet on the catching tool 4 to reduce the difficulty for infants and young children to catch the tagged fish 2. In other embodiments, the counterweight 22 may also be an object such as a high-density mineral block.

[0047] Furthermore, the total weight of the marker fish 2 is W, and the maximum buoyancy of the marker fish 2 when fully submerged in water is F. To allow the marker fish 2 to be in various positions such as floating on the surface, submerged, or at the bottom, W and F must have the following relationship: 0.8F ≤ W ≤ F. When W < F, the marker fish 2 floats on the surface. However, if the total weight of the marker fish 2 is too small, its center of gravity will be above the water, resulting in an unattractive floating "posture," and the marker fish 2 may lie flat on the surface. Therefore, it is necessary to ensure that the entire counterweight is below the water surface for the marker fish 2 to have a more aesthetically pleasing and realistic "posture." After multiple simulation tests, the above objective can be achieved when W ≥ 0.8F. When W = F, the marker fish 2 can completely sink in the water, but because gravity and buoyancy cancel each other out, the position of the marker fish 2 is determined by its inertia upon entering the water, making its position in the interactive basin 12 more random.

[0048] Furthermore, to prevent children from accidentally swallowing the marker fish 2 and choking on it, the marker fish 2 is equipped with a through hole 23, which runs through the body 21 and the counterweight 22 along the length of the marker fish 2. The through hole 23 ensures that even if an infant or toddler accidentally swallows the marker fish 2, the infant or toddler can still breathe to a certain extent, providing more time to handle the accident. Of course, the marker fish 2 should be designed to be larger than the mouth size of a typical infant or toddler to avoid such accidents. The through hole 23 also serves as a marker for the center of gravity of the marker fish 2, used to determine whether the weight of the marker fish 2 meets the floating requirements at the factory.

[0049] like Figures 2-3 As shown, in this embodiment, the catching tool 4 is a fishing net. A fishing net is convenient for infants and toddlers just beginning training, as the catching process is relatively simple and easy to operate. However, for older infants and toddlers, the fishing net, being too simple, cannot meet their needs for fun. Therefore, in other embodiments, the catching tool 4 can also be a fishing rod with a magnet. A magnet is attached to the end of the fishing line of the fishing rod, combined with the magnetically attracted metal part in the marked fish 2, to achieve the fishing game, which is more difficult than using a fishing net. However, it should be noted that the magnet can easily be swallowed by infants and toddlers, causing safety issues. Infants and toddlers should be prevented from using the infant and toddler fun and educational toy box 100 alone as much as possible.

[0050] In summary, the infant and toddler fun early education kit provided in this embodiment makes the process of early education more fun for infants and toddlers by catching three-dimensional marked fish in an interactive basin and placing the caught marked fish in various classification compartments according to the characteristics of the label board, while ensuring the guiding and training effects of the teaching aid.

[0051] Secondly, the infant and toddler fun and educational toy box provided in this embodiment can screen the visual development of infants and toddlers by matching the colors of the marked fish and the label board, thus serving as a color blindness screening and health care function. In addition, the infant and toddler fun educational toy box provided in this embodiment places the marked fish in the water in the interactive basin, making the position of the marked fish random. During the catching process, infants and toddlers can also conduct attention training and patience training at the same time, and further obtain better training results.

[0052] Example 2: Please Figures 1-6 Based on the above, refer to Figures 7-10 This embodiment provides an infant and toddler fun and educational toy box 100, which is a modification and adjustment based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the box support 11 further includes a hook 114, which is disposed on the side adjacent to the first chamber 111 and the second chamber 112. The box assembly 1 also includes a storage box 14, which is fixed to the box support 11 by the hook 114.

[0053] For ease of description, such as Figures 7-8 As shown, the hook 114 in this embodiment is located on the right side relative to the second chamber 112, facilitating operation or opening of the storage box 14 with the right hand. Alternatively, for those who primarily use their left hand, the hook 114 can be located on the left side of the second chamber 112. Considering the universality of the teaching aids, the storage box 14, as an extension module, primarily facilitates the storage of multiple sets of teaching aids for use by infants and toddlers of different ages, increasing the utilization rate of the infant and toddler fun and educational teaching aid box 100. For example, the fishing rod, the more complex marking fish 2, and the label board 3 mentioned in Embodiment 1, suitable for older infants and toddlers, can all be placed in the storage box 14 when not in use. The hook is secured to the side of the box bracket 11 to prevent forgetting it during transport. When filling the interactive basin 12 with water, the storage box 14 can also serve as a water container, completing the water filling process.

[0054] For further information, please refer to [link / reference]. Figures 7-9 The storage box 14 is provided with a hanging slot 141. The hook 114 enters and engages with the hanging slot 141, fixing the storage box 14 to the side of the box body support 11. After being fixed to the box body support 11, the top surface of the storage box 14 is flush with the top surface of the box body support 11, making the entire infant and toddler fun and educational toy box 100 neater and more aesthetically pleasing. It also allows for verification that the storage box 14 is completely fixed to the box body support 11, preventing the storage box 14 from detaching from the box body support 11 during transport.

[0055] Furthermore, the storage box 14 is equipped with a lid 142 and a retaining plate 143. The lid 142 is horizontally slidable and positioned at the top of the storage box 14. Items such as the marker fish 2 and label board 3 from the same kit are placed together in the storage box 14, and the lid 142 is inserted to complete the storage. Near the box body support 11, the lid 142 has an insertion hole 1421. The retaining plate 143 is vertically movable within the hanging slot 141. When the hook 114 engages with the hanging slot 141, the hook 114 lifts the retaining plate 143, allowing it to be inserted into the insertion hole 1421. Figure 10 As shown, the hook fastener 114 has a mushroom-shaped structure. When its larger end is engaged with the hanging slot 141, it lifts the latch plate 143. The top of the latch plate 143 has a pin-like structure. The latch plate 143 with the pin-like structure is inserted into the insertion hole 1421, restricting the opening of the lid 142. This ensures that when the lid 142 is closed and the storage box 14 is fully engaged with the box body support 11, the lid 142 cannot be opened directly by external force. This effectively prevents infants and young children from accidentally opening the storage box 14 out of curiosity, thereby preventing accidents such as accidental swallowing or pinching.

[0056] In some embodiments, to further enhance safety, even after the latch 143 is inserted into the socket 1421, it cannot disengage from the socket 1421 to unlock the lid 142, even if the hook 114 is no longer pressing against it. Special external force is required, such as using a tool to press the latch 143 in the opposite direction at the socket 1421. Alternatively, a reverse latching position can be provided on the hanging slot 141, allowing the hook 114 to press against the other side of the latch 143 in the opposite direction, thus disengaging the latch 143 from the socket 1421 and unlocking the lid 142.

[0057] Example 3: Please Figures 1-10 Based on the above, refer to Figures 11-12 This embodiment provides an infant and toddler fun and educational toy box 100, which is an upgrade and adjustment based on Embodiment 1 or Embodiment 2. The difference is that different numbers or letters are printed on the same style of marker fish 2 body 21, while the label plate 3 is printed with numbers or letters that match the marker fish 2. Infants and toddlers can learn and understand numbers or letters by placing the caught marker fish 2.

[0058] During the training process, each sorting grid 131 can also be filled with a certain amount of water, making the sorting grid 131 form a "small pond". When the infants and toddlers complete the sorting and put the marked fish 2 into the sorting grid 131, the marked fish 2 floats in the sorting grid 131, making the whole sorting process more vivid and natural.

[0059] Furthermore, in some embodiments, to prevent infants from tipping over the box support 11, multiple vacuum suction cups 115 are provided at the bottom of the box support 11. The box support 11 is fixed to the table or ground by the vacuum suction cups 115, ensuring that infants cannot push over the box support 11, thereby ensuring that the water in the interactive basin 12 or the sorting compartment 131 will not spill out.

[0060] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
