[0062] Embodiment 1

[0063] like Figure 1 As shown, the bathtub assembly 100 includes a bathtub 101 and a composite bathing frame 102 placed in the bathtub 101. The composite bathing frame 102 is placed in the bathtub 101, and the height of the bathtub 101 exceeds the height of the composite bathing frame 102. When in use, the infant lies in the composite bathing frame 102, and if necessary, the water in the bathtub 101 can fully cover the body of the infant, so that the infant can be fully immersed in the warm bath.

[0064] like Figure 2As shown, the composite bath rack 102 includes a support leg 10 and a bath rack 20 with a three-dimensional curved surface structure, and the support leg 10 is installed on the back of the bath rack 20. The support leg 10 is connected to the back of the bath rack 20 with limited rotation, and the support leg 10 is rotated to a certain angle and locked to adjust the inclination of the composite bath rack 20, so as to meet the user's use requirements and avoid slipping or discomfort caused by improper angles.

[0065] like Figures 3 to 6 As shown, the bath rack 20 includes a bath rack body 21 formed of a first plastic material and a lying body 22 formed of a second plastic material, and the bath rack body 21 is annular in structure. Subsequently, the lying body 22 is assembled onto the bath rack body 21 to form a complete composite bath rack 102.

[0066] The annular structure of the bath rack body 21 provides an independent area for the assembly of the lying body 22. During the injection molding process, the annular structure provides a clear reference frame to define the connection area between the bath rack body 21 and the lying body 22, ensuring the precise positioning of the lying body 22 during assembly, thereby avoiding joint defects such as gaps, misalignment or uneven stress distribution.

[0067] Moreover, the annular structure forms an air-avoiding area to save injection molding materials, thereby reducing production costs. Reducing the use of materials also means that the weight of the final product will be reduced, which makes the bath rack easier to carry and operate. On the other hand, the existence of the air-avoiding area provides a direct drainage path for the water leakage hole b3 on the lying body 22, improves drainage efficiency, and reduces the retention time of water on the bath rack; the drying time of the bath rack is shortened, which helps to reduce bacterial growth.

[0068] In addition, the annular structure of the bath rack body 21 may help to design a more uniform hot runner during the injection molding process, thereby improving the quality and consistency of the injection molded parts.

[0069] The bath rack body 21 includes a circumferential side portion a1 and a first connecting portion a2 extending inward from the upper end of the circumferential side portion a1 and distributed in a circumferential direction. The lying body 22 includes a lying portion b1 and a second connecting portion b2 extending toward the circumferential side portion a1. The design of the circumferential side portion a1 and the first connecting portion a2 provides a solid support point for the lying body 22, thereby enhancing the structural stability of the entire bath rack. Moreover, the circumferential side portion a1 and the first connecting portion a2 can simplify the assembly process because they can be formed as a whole through an injection molding process at one time, reducing the number of subsequent processes. Figure 6 and Fig.11 As shown, since the structure at the connection part is strengthened, the whole bath rack can bear a larger load and is suitable for infants and young children of different weights.

[0070] like Figure 3As shown, the lying body 22 is connected to the surrounding side portion a1 through the second connecting portion b2. Both the second connecting portion b2 and the surrounding side portion a1 have an outwardly protruding arc, and the arcs of the two match each other to ensure a smooth transition between the lying body 22 and the bath rack body 21 after injection molding, thereby improving the comfort of infants and young children when lying down.

[0071] In addition, the lying part b1 is a three-dimensional curved structure, and a plurality of water leakage holes b3 are provided on the lying part b1. Both the arc transition between the connecting parts and the three-dimensional curved structure are to better adapt to the body curve of infants and provide a more comfortable lying experience. Specifically, Figure 5 As shown, the three-dimensional bending structure means that the lying part b1 is not only bent on one plane, but also has a bending range in three-dimensional space (not only has a downward concave range, but also extends in an arc shape when extending forward, backward, left and right), so as to better adapt to the three-dimensional shape of the human body.

[0072] Furthermore, the three-dimensional curves provide additional support points, helping to distribute the weight of the infant and toddler, reducing pressure in any single area. By carefully designing the bends, the amount of material used can be reduced without sacrificing structural strength and function.

[0073] Additionally, the three-dimensional curved structure can reduce the number of seams and edges in the product, which helps to simplify the cleaning process and reduce potential scratch or wear points.

[0074] The bath rack body 21 and the lying body 22 are formed together by injection molding, so that the first connecting portion a2 and the second connecting portion b2 are overlapped and combined together. The bath rack body 21 and the lying body 22 are combined together by injection molding to form a structurally integrated bath rack, which enhances the overall stability and durability.

[0075] It should also be noted that the hardness of the first plastic material is H1, and the hardness of the second plastic material is H2; H1>H2. The hardness value of H1 is 80-100 Shore, and the hardness value of H2 is 5-40 Shore. Preferably, the first plastic material is hard plastic, and the second plastic material is flexible plastic. By selecting plastic materials with different Shore hardness values, the hardness can be customized according to the different functional requirements of the bath rack body and the reclining body, thereby optimizing the performance of the product.

[0076] The first plastic material with higher hardness (H1, 80-100 Shore A) can be used for the main body of the bath rack to provide the necessary structural strength and durability. The second plastic material with lower hardness (H2, 5-40 Shore A) can be used for the body to increase softness and make the infant more comfortable when lying. The flexible plastic (second plastic material) can better absorb and disperse the impact force and protect the infant from the injury of the impact.

[0077] The thickness of the lying part b1 is 10-20 mm, which can provide sufficient cushioning to make infants feel comfortable when lying down, while reducing the discomfort that may be caused by hard surfaces. The appropriate thickness can provide good support for the back and body of infants and help them maintain a stable posture in the water.

[0078] Proper thickness helps distribute the material more evenly during the injection molding process and reduces internal stress.

[0079] Moreover, the thickness of 10-15 cm indicates that the lying portion b1 can increase its durability and deformation resistance. After being compressed when lying down, the lying portion b1 can rebound in a relatively short time and is not easy to collapse even after long-term use, thereby improving the comfort of use.

[0080] The drainage holes b3 are distributed in an array. The array distribution can ensure uniform drainage of the entire surface of the lying portion b1 and prevent water from accumulating in a specific area. The regular distribution of drainage holes helps to reduce material expansion or deformation caused by water retention, thereby improving the durability of the product.

[0081] More specifically, the lying portion b1 includes a peripheral region b11 and a middle region b12 provided with a water leakage hole b3, and the peripheral region b11 and the middle region b12 have a continuous arc transition. The middle region b12 has a convex structure v relative to the peripheral region b11, and the convex structure v of the middle region b12 relative to the peripheral region b11 can enhance the structural stability of the lying portion and provide better support.

[0082] Preferably, the cross section of the water leakage hole b13 is triangular, rectangular, hexagonal or circular. The corresponding shape can be selected according to the specific requirements of the product, or various shapes can be used in combination.

[0083] Embodiment 2

[0084] like Figure 1 As shown, the bathtub assembly 100 includes a bathtub 101 and a composite bathing frame 102 placed in the bathtub 101. The composite bathing frame 102 is placed in the bathtub 101, and the height of the bathtub 101 exceeds the height of the composite bathing frame 102. When in use, the infant lies in the composite bathing frame 102, and if necessary, the water in the bathtub 101 can fully cover the body of the infant, so that the infant can be fully immersed in the warm bath.

[0085] like Figure 2As shown, the composite bath rack 102 includes a support leg 10 and a bath rack 20 with a three-dimensional curved surface structure, and the support leg 10 is installed on the back of the bath rack 20. The support leg 10 is connected to the back of the bath rack 20 with limited rotation, and the support leg 10 is rotated to a certain angle and locked to adjust the inclination of the composite bath rack 20, so as to meet the user's use requirements and avoid slipping or discomfort caused by improper angles.

[0086] In this embodiment, Figures 7 to 10 As shown, the bath rack 20 includes a bath rack body 21 formed of a first plastic material and an upper lying portion layer d formed of a second plastic material.

[0087] like Figure 7 As shown, the bath rack body 21 includes an integrally formed peripheral side portion c1 and a lower lying portion layer c2. That is, in this embodiment, the peripheral side portion c1 and the lower lying portion layer c2 are integrally formed, and the middle area of ​​the entire bath rack body 21 is a solid lower lying portion layer c2. The integrally formed peripheral side portion c1 and the lower lying portion layer c2 provide a seamless and solid base, which enhances the integrity and durability of the bath rack. Moreover, the solid lower lying portion layer c2 provides additional support and strength, which helps to withstand the weight and activities of infants and young children.

[0088] The continuous transition between the side portion c1 and the lower lying portion layer c2 is preferably a continuous arc transition. The continuous arc transition helps to enhance the continuity and aesthetics of the structure. The continuous arc transition can reduce hard edges or sharp corners and provide a more comfortable user experience, especially when infants and young children are lying down.

[0089] The upper lying part layer d and the lower lying part layer c2 are combined together by injection molding process to form the lying part 23 of the bath rack. The injection molding process can realize the seamless combination of the two parts, provide a smoother and cleaner appearance, and reduce the assembly steps. Injection molding can ensure that the combination between the upper lying part layer d and the lower lying part layer c2 is very strong, and enhance the structural strength of the entire lying part 23.

[0090] Although the upper lying portion layer d and the lower lying portion layer c2 are integrally formed, they can be independently designed to meet specific functional requirements, such as different thickness, hardness or drainage characteristics.

[0091] The two-layer structure can provide stronger support than a single layer and is suitable for infants of different weights. The upper lying layer is made of flexible plastic material, which increases the softness of the lying area and improves the comfort of infants. A specific drainage channel can be designed between the two layers to improve the efficiency of water discharge and keep the lying area dry.

[0092] The upper lying layer d includes a peripheral area and a middle area with an upper water leakage hole, and the middle area is convex relative to the peripheral area. The thicker area is formed into a convex structure, which can effectively reduce the internal stress of the overlapping part and improve the durability of the product.

[0093] Specifically, the lying portion 23 has a three-dimensional curved structure, and a plurality of water leakage holes are provided on the lying portion 23. The three-dimensional curved structure of the lying portion 23 means that the lying portion 23 is not only curved on one plane, but also has a curved range in three-dimensional space (not only has a downward concave range, but also extends in an arc shape in the forward, backward, left and right extensions), so as to better adapt to the three-dimensional shape of the human body.

[0094] Furthermore, the three-dimensional curves provide additional support points, helping to distribute the weight of the infant and toddler, reducing pressure in any single area. By carefully designing the bends, the amount of material used can be reduced without sacrificing structural strength and function.

[0095] Additionally, the three-dimensional curved structure can reduce the number of seams and edges in the product, which helps to simplify the cleaning process and reduce potential scratch or wear points.

[0096] The drainage holes include an upper drainage hole e1 opened in the upper lying layer d and a lower drainage hole e2 opened in the lower lying layer c2, and the upper drainage hole e1 is connected with the lower drainage hole e2. This structure is intended to illustrate that there is a specific drainage channel between the two layers, which can achieve the required water discharge efficiency and keep the lying area dry.

[0097] The hardness of the first plastic material is H1, and the hardness of the second plastic material is H2; H1>H2. The hardness value of H1 is 80-100 Shore, and the hardness value of H2 is 5-40 Shore. Preferably, the first plastic material is hard plastic, and the second plastic material is flexible plastic. By selecting plastic materials with different Shore hardness values, the hardness can be customized according to the different functional requirements of the bath rack body and the reclining body, thereby optimizing the performance of the product.

[0098] The first plastic material with higher hardness (H1, 80-100 Shore A) can be used for the main body of the bath rack to provide the necessary structural strength and durability. The second plastic material with lower hardness (H2, 5-40 Shore A) can be used for the body to increase softness and make the infant more comfortable when lying. The flexible plastic (second plastic material) can better absorb and disperse the impact force and protect the infant from the injury of the impact.

[0099] Preferably, the water leakage holes are distributed in an array. The cross section of the water leakage hole b13 is triangular, rectangular, hexagonal or circular. The specific technical effects have been described in detail in the first embodiment, which will not be repeated here.

[0100] In addition, it should be noted that the diameter of the upper water leakage hole is larger than that of the lower water leakage hole; the larger diameter of the upper water leakage hole can speed up the water flow, improve the drainage efficiency, and reduce the residence time of water on the surface of the lying part. Moreover, the different settings of the hole diameters can make the lying part structure more reasonable, quickly drain water through the larger hole diameter of the upper part, while keeping the lower hole diameter smaller to maintain the structural integrity.

[0101] The thickness of the upper lying part layer d is 10-20mm. Based on the material of this part, this thickness enables the upper lying part layer d to increase its durability and deformation resistance. After being compressed when lying down, the lying part b1 can rebound in a shorter time and is not easy to collapse even after long-term use, thereby improving the comfort of use.

[0102] The thickness of the lower lying layer c2 is 2-5 mm. The lower lying layer c2 has a relatively high hardness, and at this thickness, strong support, structural stability and load-bearing capacity can be achieved.

[0103] The upper lying layer d extends around the peripheral side c1 to form a soft side edge covering a part of the peripheral side c1. The soft side edge provides additional cushioning, so that infants and young children feel a softer touch when using the bath rack, increasing the comfort when lying. The soft side edge provides a better grip, making the carrying process more stable and comfortable.

[0104] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
