It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. The terms "first" and "second" are only for descriptive convenience and have no other directional meaning, and should not be construed as limiting the present utility model.

[0076] As Figure 7 shown, this embodiment provides a composite bathing chair 100 for placing in a bathtub 200 for use by special groups such as infants.

[0077] As Figures 1 - 5As shown in the figure, the composite bathing chair 100 includes a chair frame 1 and a contact body 2 for contacting the human body. The chair frame 1 is made of hard plastic, such as PP, PE, etc. It has high strength and stability and is the supporting component of the entire bathing chair, capable of supporting various movements of the infant during bathing.

[0078] The contact body 2 is located in the middle of the chair frame 1 and is formed of TPE thermoplastic elastomer, and includes a honeycomb structure portion 3 having a plurality of three-dimensional hollow grids j. The TPE thermoplastic elastomer has excellent softness and skin-friendly properties, and can fit the body curve of the infant, providing a comfortable touch.

[0079] Specifically, the honeycomb structure portion 3 having a plurality of three-dimensional hollow grids j prepared from TPE thermoplastic elastomer has at least the following advantages.

[0080] First, this unique 3D three-dimensional grid structure not only endows the contact body 2 with excellent resilience performance, but also greatly improves its dynamic fitting ability with the human body curve. This design enables the bathing chair to automatically adjust its shape according to the body shape and movement changes of the infant to achieve the best support effect.

[0081] Second, the design of the three-dimensional hollow grids j of the honeycomb structure portion 3 effectively disperses various pressures that the infant may exert during bathing through its geometric shape and spatial layout. This uniform pressure distribution not only improves the comfort of the infant, reduces the local compression feeling that may be caused by long-term use, thereby protecting the delicate skin of the infant, but also the honeycomb cross-linked body forming the three-dimensional hollow grids j is integrally formed, enabling the structures at this part to support each other, avoiding stress concentration during use by evenly dispersing the pressure, and improving the durability of the bathing chair.

[0082] Third, this design cleverly utilizes the structural characteristics of the material itself to achieve the functions of water permeability and air permeability, thereby ensuring the rapid drainage and cleaning of the bathing chair without relying on traditional drainage holes. This design not only simplifies the product structure, reduces the complexity during the manufacturing process, but also improves the practicality of the product and the convenience of maintenance.

[0083] Fourth, the water permeability and air permeability functions of the three-dimensional hollow grids j help to reduce the water retention on the surface of the bathing chair, which means that the bathing chair can dry faster after use, reducing the problems of mildew, peculiar smell, and the possibility of bacterial growth caused by a humid environment, and providing a more hygienic bathing environment for the infant.

[0084] In addition, by using two different materials for the contact body 2 and the chair frame 1, their respective advantages can be brought into play. Both are thermoplastic materials and can be integrally formed by injection molding processes, including two-shot injection molding or two-color injection molding processes, thus eliminating the need for additional connectors or adhesives for assembly. This integral molding technology not only simplifies the production process, reduces the cumbersome assembly operations, and lowers the manufacturing cost, but more importantly, it greatly improves the bonding ability between the contact body 2 and the chair frame 1. This tight bonding ensures the stability and durability of the baby bath chair when bearing the activities of infants and significantly enhances the integrity and strength of the product.

[0085] Furthermore, due to the thermoplastic properties of the two materials, they can form a seamless bond during the injection molding process, thus eliminating the potential weaknesses of traditional assembly methods, such as cracking or loosening at the seams. This seamless bonding technology significantly improves the safety of the baby bath chair, ensures the safety of infants during use, and also significantly extends the service life of the product. Through this innovative material and technical solution, the baby bath chair of the present invention not only provides a better user experience but also offers a more solid guarantee for the healthy growth of infants.

[0086] Generally speaking, the hardness value of the chair frame 1 is 80 - 100 Shore. The hardness value of the contact body 2 is 15 - 40 Shore.

[0087] Preferably, as Figures 3 - 6 shown, the contact body 2 is adapted to the functional structure of the baby bath chair, including a seat portion 21 and a back portion 22. The seat portion 21 is used to support the buttocks of the infant, and the back portion 22 is used for the infant to lean on, thereby improving the convenience and safety of children's bathing. It should be noted that the contact body 2 is flexibly configured with a honeycomb structure portion 3. The seat portion 21 and the back portion 22 can be independently or jointly equipped with the honeycomb structure portion 3, that is, the honeycomb structure portion 3 can be located at any one or both of the seat portion 21 and the back portion 22 to meet different usage requirements. Whether it is for key protection of specific parts or improvement of overall comfort, it can easily be satisfied, demonstrating excellent human care and flexible usage advantages.

[0088] In this preferred embodiment, as Figure 6 shown, the back portion 22 is a sheet structure, and the seat portion 21 includes a peripheral portion p continuous with the back portion 22. The honeycomb structure portion 3 is located in the middle of the peripheral portion. Such a design not only ensures the support of the back portion 22, taking into account the physiological characteristics of the infant's back 22, the sheet structure of the back portion 22 provides a solid support point for the infant, ensuring stability and safety during the bathing process. In addition, it highlights the comfort and drainage of the seat portion 21. The continuity of the peripheral portion of the seat portion 21 and the back portion 22 ensures the consistency and coordination of the overall structure and also provides a physical structure basis for the combination of the contact body 2 and the frame.

[0089] Due to the continuous structure of the back part 22, and the back part 22 extends upward at an angle with the seat part 21, water can flow along the back part 22 to the seat part 21 and be discharged through the honeycomb structure part 3 of the seat part 21, avoiding the problem of water retention in the bath chair and being more conducive to the drying of the bath chair during the storage process.

[0090] As Figures 3 - 4 As shown, the chair frame 1 includes a seat support part 11 and a back support part 12. The seat support part 11 has an annular structure and the bottom forms an annular placement surface m, which is convenient for stable placement in a bathtub or other bathing containers. The back support part 12 extends upward from the upper side of the rear section of the seat support part 11 to provide support for the back 22 of the infant. The upper edges of the seat support part 11 and the back support part 12 form a continuous connection part n. The edge of the contact body 2 forms a wrapping part and wraps the connection part n.

[0091] This continuous design not only enhances the integrity of the bath chair in terms of structure, but also provides a smooth sense of line visually. The edge of the contact body 2 forms a wrapping part and cleverly wraps the connection part n. This design not only realizes the tight combination between the chair frame 1 and the contact body 2, but also enhances the aesthetics and overall sense of the product.

[0092] Moreover, this tightly combined design also helps to reduce the looseness or deformation that may occur during the use of the bath chair, improving the durability and reliability of the product. The design of the wrapping part also takes into account the safety of infants and avoids the harm that may be caused by sharp edges.

[0093] As Figure 2 、 3 As shown in 5 and 6, a vertical foot separation column 112 is provided on the front side of the seat support part 11; a notch y corresponding to the foot separation column is provided on the front side of the seat part 21; the honeycomb structure part 3 is located in the seat part 21 and extends to the edge of the notch y on the front side; the annular seat support part 11 forms a placement part 111 at the rear edge of the foot separation column 112, that is, a placement part 111 is formed at the front edge of the through hole V; the notch edge of the honeycomb structure part 3 is placed on the placement part 111; the lower surface of the honeycomb structure part 3 is exposed from the through hole V, thereby improving the support and comfort of the load-bearing part of the chair.

[0094] As Figure 3 、 5, as shown in Figure 6, the backrest 22 includes a rear support portion a and two forward-extending portions b on both sides. The upper edge of the support portion a, the extending portion b, and the outer edge of the seat portion 21 form a continuous curve. Correspondingly, the back support portion 12 includes a rear portion c and two side portions d. The upper edge of the support portion a is connected to the upper edge of the rear portion c to form an upper wrapping edge area e. There is a gap between the support portion a and the rear portion c, and the two form a triangular support structure, which not only stabilizes the structure but also makes the chair lighter. The side portion d and the extending portion b together form an armrest structure, and the outer edge of the extending portion b is connected to the upper edge of the side portion d to form a side wrapping edge area f. The outer edge of the seat portion 21 wraps around the outside of the seat support portion 11 to form a bottom wrapping edge area g. The upper wrapping edge area e, the side wrapping edge area f, and the bottom wrapping edge area g are all in an arc structure.

[0095] The upper wrapping edge area e provides flexible support for the back 22, neck, or head of the infant, and the side wrapping edge area provides flexible support for the infant's arms, thus providing a more comfortable bathing environment for the infant.

[0096] In addition, the thickness of the backrest 22 and the peripheral portion p is 2 - 4 mm. This thickness selection is carefully considered, which not only ensures the lightness of the material but also guarantees sufficient strength and durability. This appropriate thickness enables the bathing chair to remain stable when bearing the weight and activities of the infant, while avoiding the heaviness that may be brought by too thick materials, ensuring the light portability and easy storage of the product.

[0097] The honeycomb structure portion 3, as a key component of the bathing chair, is designed with a thickness of 8 - 15 mm. This thickness range provides a softer and more comfortable contact experience for the infant. The three-dimensional hollow design of the honeycomb structure portion 3, combined with this specific thickness, not only enhances its resilience but also provides a good buffering effect, being able to better adapt to the body curve of the infant and reduce the possible pressure during the bathing process.

[0098] As Figure 3 shown, the honeycomb structure portion 3 includes multiple layers of stacked honeycomb cross-linked bodies k. Each layer of honeycomb cross-linked body includes a plurality of three-dimensional hollow grids j. The thickness and elasticity of the contact body 2 are increased by the stacking method, providing a softer and more comfortable sitting feeling for the infant. Moreover, each layer of cross-linked body supports each other, evenly dispersing the pressure during use, avoiding local stress concentration, and extending the service life of the product. Between adjacent layers of honeycomb cross-linked bodies, the three-dimensional hollow grids j are staggered from each other, further enhancing the support and water permeability of the structure.

[0099] Preferably, the size of the three-dimensional hollow grids j of the multiple layers of honeycomb cross-linked bodies gradually increases from top to bottom. This design of increasing size optimizes the drainage performance of the bathing chair. As the grid size increases, the path for water flow becomes wider, thus accelerating the drainage speed and reducing the water retention on the surface and inside of the bathing chair.

[0100] Preferably, the grid shape is preferably triangular or regular hexagonal to improve the stability and strength of the structure. As one of the most basic polygons, the triangle exhibits excellent stability when bearing pressure due to the balance and symmetry of its structure. Selecting a triangular grid not only enhances the structural stability of the baby bath chair but also improves the overall load-bearing capacity. During the baby bath process, the triangular grid can effectively disperse and absorb the forces generated by the baby's activities, making the bath chair less likely to suffer from structural damage during use. Even under long-term use and frequent cleaning, it can still maintain a good state.

[0101] The above has introduced the composite baby bath chair provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
