[0016] Reference Figure 1-2 According to a first aspect of the present invention, a washable silicone rubber memory pillow is characterized in that it comprises a memory foam layer 1 for pressure cushioning and a silicone rubber sponge layer 2 for balance support, which are stacked sequentially from top to bottom. The memory foam layer 1 and the silicone rubber sponge layer 2 are fixedly connected by adhesive bonding or sewing. The connecting surface between the memory foam layer 1 and the silicone rubber sponge layer 2 is set as a wavy surface 3 in the shape of a "3". The wavy surface 3 is provided with two convex surfaces 31 and a concave surface 32 between the two convex surfaces 31. Both the front and rear ends of the memory foam layer 1 are provided with a support portion 11 for supporting the neck, which wraps around the silicone rubber sponge layer 2. A concave portion 12 for placing the head is provided between the two support portions 11 and located above the concave surface 32.

[0017] A washable silicone rubber memory pillow according to an embodiment of the present invention has at least the following beneficial effects: The present invention employs a layered structure combining a memory foam layer 1 and a silicone rubber sponge layer 2, with the memory foam layer 1 providing soft and conforming pressure cushioning, and the silicone rubber sponge layer 2 providing stable and durable balanced support. The two work synergistically to enhance the overall comfort and support of the pillow. Specifically, by setting the connecting surface between the memory foam layer 1 and the silicone rubber sponge layer 2 as a wavy surface 3 in the shape of a "3", the memory foam layer 1 can naturally form two supports for the neck based on this wavy surface 3. The pillow features a support portion 11 and a centrally located recessed portion 12 for head placement. This integrated structure allows the pillow to precisely differentiate and adapt to the head placement area and neck support area of ​​the human body. The recessed portion 12 gently wraps around the head, while the support portion 11, supported by the convex surface 31, effectively supports the cervical spine and maintains its natural physiological curvature, thereby significantly improving the sleep experience and health benefits for users, especially those with cervical discomfort. At the same time, the memory foam layer 1 and the silicone rubber sponge layer 2 are fixedly connected by adhesive or stitching, resulting in a stable structure that prevents misalignment between layers, ensuring the reliability and durability of the product during use.

[0018] According to some embodiments of this utility model, the memory foam layer 1 is made of slow-rebound memory foam material with a density of 30-50D, and its interior is uniformly distributed with breathable pores with a diameter of 0.5-3mm. This specific density range of memory foam material provides a sufficiently soft pressure cushioning experience, achieving pressure-free support for the head and neck, while maintaining necessary support to prevent excessive collapse and ensure optimal performance of the slow-rebound characteristics. More importantly, the uniformly distributed micron-level breathable pores within it form efficient air micro-circulation channels. These channels can promptly dissipate heat and moisture generated by the head during sleep, effectively solving the common problems of stuffiness and sweat accumulation in traditional memory foam materials due to their dense texture, greatly improving the pillow's breathability and dryness. Simultaneously, these through-hole structures facilitate rapid water entry and exit when the pillow is washed, significantly shortening drying time and reducing the risk of mold growth due to internal dampness, thus fundamentally enhancing the pillow's washability and ease of maintenance.

[0019] According to some embodiments of the present invention, the silicone rubber sponge layer 2 is made of slow rebound silicone rubber sponge with a density of 40-80D, and has an interconnected honeycomb-shaped air-permeable channel structure inside. The air-permeable channel structure includes a dense microporous layer with an average pore size of 50-100μm, a main support pore layer with an average pore size of 200-400μm, or a through-type air-guiding channel with an average pore size of 500-800μm. This density configuration gives the silicone rubber sponge layer 2 superior resilience compared to ordinary support materials. It effectively supports the upper memory foam layer and the pressure of the head and neck, preventing the pillow from collapsing. Furthermore, its slow rebound properties absorb and disperse pressure, creating an ideal balance of softness and firmness with the memory foam layer 1. Its meticulously designed, interconnected multi-scale pore structure—including a dense microporous layer with an average pore size of 50-100 μm, a main support pore layer of 200-400 μm, and through-hole air channels of 500-800 μm—together constitutes a highly efficient three-dimensional ventilation system. The dense microporous layer… Facilitating moisture adsorption and initial diffusion, the main support pore layer promotes lateral airflow while ensuring structural strength, while the large-diameter through-hole air channels enable rapid air exchange and heat dissipation in the vertical direction inside the pillow core. This composite structure fundamentally solves the technical contradiction that high-support materials are often not breathable, achieving a unity of support and ultimate breathability. In addition, the inherent water-resistant and anti-aging properties of silicone rubber, combined with its open pores that facilitate rapid moisture passage and evaporation, give the entire support layer and even the pillow as a whole excellent durability and the practical advantages of easy cleaning and maintenance.

[0020] According to some embodiments of the present invention, the minimum distance between the two convex surfaces 31 of the wave surface 3 and the upper surface of the support part 11 is 2-4cm, and the distance between the upper surface of the support part 11 and the lower surface of the silicone rubber sponge layer 2 is 5-15cm. This scientifically designed size configuration creates a gradient in the pillow's support structure. A 2-4cm local height difference ensures that the support portion 11 forms a sufficiently raised, effective support surface, providing firm and just-right support for the neck. This effectively maintains the natural physiological curvature of the cervical spine, preventing insufficient support that could lead to the cervical spine being unsupported or excessively bent. Simultaneously, the overall height range of 5-15cm precisely adapts to the differences in shoulder width and head-neck ratio among most users. This ensures that the head and spine remain horizontal when lying on the side, preventing shoulder pressure, and that the head and body form a comfortable angle when lying on the back. This comprehensively meets the diverse needs for pillow height in different sleeping positions, significantly improving comfort and health support during sleep. Furthermore, this optimized structural size makes the transition between the head concave portion 12, guided by the wave surface 3, and the neck support portion 11 smoother and more natural, effectively preventing the risk of neck sprains due to changes in posture during sleep, and enhancing the product's safety and ergonomic adaptability.

[0021] The embodiments described above with reference to the accompanying drawings have been described in detail. However, the embodiments are not limited to those described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
