Description

Technical Field

[0001] This utility model relates to the field of home furnishing technology, specifically to a pillow, and more specifically, to a washable, highly breathable silicone rubber memory pillow. Background Technology

[0002] Memory foam pillows are popular for their comfort and support, but traditional memory foam pillows often suffer from poor breathability and are not easy to wash, leading to the accumulation of sweat, dust, and bacteria during use, affecting hygiene and health. In existing technology, some improved pillows improve breathability by increasing ventilation holes or using breathable materials, but this often sacrifices support and durability; other pillows, while washable, are prone to deformation or loss of elasticity after washing. Therefore, there is a need for a memory foam pillow that combines high breathability, washability, and stable support to meet users' dual needs for comfort and hygiene. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a washable, highly breathable silicone rubber memory pillow, which achieves good breathability, support, and washability through a multi-layer structure design.

[0004] A washable, highly breathable silicone rubber memory pillow according to a first aspect of the present invention is characterized in that it comprises, from top to bottom, a memory foam layer for pressure cushioning, at least two elongated neck support layers, and a silicone rubber sponge layer for balance support, wherein the memory foam layer, the neck support layer, and the silicone rubber sponge layer are fixedly connected by adhesive bonding or sewing; the connecting surface between the memory foam layer, the neck support layer, and the silicone rubber sponge layer is configured as an S-shaped wavy surface, and at least two of the neck support layers are respectively disposed at the trough and crest of the wavy surface.

[0005] Based on the technical solution of the first aspect embodiment described above, the washable and highly breathable memory pillow provided by this utility model has the following beneficial effects: First, by designing an S-shaped wave-like connecting surface and placing at least two elongated neck support cotton layers at the crests and troughs of this wave, a three-dimensional support system is formed that closely conforms to the physiological curve of the human head and neck. The support cotton layers located at the crests and troughs precisely support the protruding parts of the neck's physiological curvature, providing upward support. Furthermore, by rotating the pillow forward and backward or flipping it up and down, four different material combinations and height adjustments can be achieved, offering users a variety of choices. This coordinated "peak-trough" layout achieves dynamic adaptation to the neck and precise multi-point support, significantly improving the pillow's comfort and helping to prevent and relieve cervical fatigue.

[0006] Secondly, the multi-layered composite structure of the memory foam layer, neck support layer, and silicone rubber sponge layer works synergistically to achieve a balance between high breathability and stable support. The upper memory foam layer dissipates heat and moisture from the head through its internal ventilation holes; while the lower silicone rubber sponge layer, with its honeycomb-like interconnected structure consisting of dense micropores, main support holes, and through-hole air channels, forms an efficient air circulation channel, ensuring rapid removal of moisture and heat from the pillow core and preventing stuffiness during sleep. Simultaneously, the silicone rubber sponge layer itself possesses slow rebound properties and high support, providing a stable base for the entire pillow, preventing collapse and deformation during sleep, and ensuring lasting and stable support.

[0007] Finally, the memory foam layer, neck support layer, and silicone rubber sponge layer are fixedly connected by adhesive or stitching. Combining the material properties of silicone rubber sponge and washable memory foam, this gives the pillow excellent overall structural stability and washability. This integrated structure ensures that the layers will not shift, separate, or deform after repeated use, kneading, or even washing, firmly maintaining the initially designed S-shaped wave support surface. This ensures long-term maintenance of its excellent support and breathability, extends the product's lifespan, and greatly improves hygiene and convenience.

[0008] According to some embodiments of the present invention, the neck support cotton layer is elongated and is transversely disposed between the memory foam layer and the silicone rubber sponge layer, and the cross-section of the neck support cotton layer is a spindle shape with pointed ends and a wide middle.

[0009] According to some embodiments of this utility model, the memory foam layer 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.

[0010] According to some embodiments of the present invention, the silicone rubber sponge layer 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.

[0011] According to some embodiments of this utility model, the minimum distance between the trough of the wave surface and the upper surface of the memory foam layer is 2-6 cm.

[0012] According to some embodiments of this utility model, the minimum distance between the crest of the wave surface and the lower surface of the silicone rubber sponge layer is 2-6 cm.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figure 1-3According to a first aspect of the present invention, a washable, highly breathable silicone rubber memory pillow is characterized in that it comprises, from top to bottom, a memory foam layer 1 for pressure cushioning, at least two elongated neck support layers 2, and a silicone rubber sponge layer 3 for balance support, wherein the memory foam layer 1, the neck support layers 2, and the silicone rubber sponge layer 3 are fixedly connected by adhesive bonding or sewing; the connecting surface of the memory foam layer 1, the neck support layers 2, and the silicone rubber sponge layer 3 is configured as an S-shaped wave surface 4, and at least two of the neck support layers 2 are respectively disposed at the troughs 41 and crests 42 of the wave surface 4.

[0021] Based on the technical solution of the first aspect embodiment described above, the washable and highly breathable memory pillow provided by this utility model has the following beneficial effects: First, by setting an S-shaped wave-like connecting surface, and placing at least two elongated neck support cotton layers 2 at the crests 42 and troughs 41 of this wave surface 4, a three-dimensional support system is formed that closely conforms to the physiological curve of the human head and neck. The support cotton layers located at the crests 42 and troughs 41 can precisely support the protruding parts of the physiological curvature of the neck, providing upward support. By rotating them forward and backward or flipping them up and down, four different material combinations and height adjustments can be achieved, providing users with multiple options. This "peak-trough" coordinated layout achieves dynamic adaptation to the neck and precise multi-point support, significantly improving the comfort of the pillow and helping to prevent and relieve cervical fatigue.

[0022] Secondly, the multi-layered composite structure of the memory foam layer 1, the neck support layer 2, and the silicone rubber sponge layer 3 works synergistically to achieve a balance between high breathability and stable support. The upper memory foam layer 1 dissipates heat and moisture from the head through its internal ventilation holes; while the lower silicone rubber sponge layer 3, with its honeycomb-like interconnected structure consisting of dense micropores, main support holes, and through-hole air channels, forms an efficient air circulation channel, ensuring rapid removal of moisture and heat from the pillow core and preventing stuffiness during sleep. Simultaneously, the silicone rubber sponge layer 3 itself possesses slow rebound properties and high support, providing a stable base for the entire pillow, preventing collapse and deformation during sleep, and ensuring lasting and stable support.

[0023] Finally, the memory foam layer 1, the neck support layer 2, and the silicone rubber sponge layer 3 are fixedly connected by adhesive or stitching. Combining the material properties of silicone rubber sponge and washable memory foam, this gives the pillow excellent overall structural stability and washability. This integrated structure ensures that the layers will not shift, separate, or deform after repeated use, kneading, or even washing, firmly maintaining the initially designed S-shaped wave support surface. This ensures long-term maintenance of its excellent support and breathability, extends the product's lifespan, and greatly improves hygiene and convenience.

[0024] According to some embodiments of this utility model, the neck support cotton layer 2 is elongated and horizontally runs through the space between the memory foam layer 1 and the silicone rubber sponge layer 3. The cross-section of the neck support cotton layer 2 is a spindle shape with pointed ends and a wide middle. By setting the neck support cotton layer 2 as an elongated strip that runs horizontally through the pillow body and combining it with the spindle-shaped cross-section, linear and continuous support for the neck and shoulder area is achieved, effectively avoiding the support gaps that may occur under the neck in traditional pillows and ensuring a uniform distribution of support force. The spindle-shaped cross-section, with its pointed ends and wide middle, allows its thick middle section to precisely correspond to the main stress area of ​​the neck, providing concentrated and gentle support. Its tapering ends smoothly integrate with the memory foam layer 1 and the silicone rubber sponge layer 3, achieving a smooth transition of support force from the center to the periphery. This effectively eliminates the pressure caused by steep edges of the support body, greatly improving the pillow's fit and comfort.

[0025] 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. By using slow-rebound memory foam material with a density of 30-50D, the memory foam layer 1 can sensitively deform under the action of body temperature and pressure, accurately conforming to the curve of the human head and neck, achieving uniform pressure distribution, effectively relieving pressure on key parts such as the auricle and carotid artery, thereby significantly improving the comfort and relaxation effect of the pillow; at the same time, the breathable pores with a diameter of 0.5-3mm uniformly distributed inside not only greatly increase the specific surface area of ​​the material, forming an efficient heat dissipation channel that runs through the inside of the pillow core, but also effectively solve the problem of traditional memory foam material being prone to stuffiness. Moreover, these pores also provide additional deformation space during the slow rebound process, so that the material maintains good support while also having better softness and breathability.

[0026] According to some embodiments of the present invention, the silicone rubber sponge layer 3 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 breathable pore structure achieves efficient moisture management through the capillary action of the dense microporous layer. The main support pore layer ensures that the material maintains structural integrity and resilience stability under pressure, while the through-type air ducts establish a low-resistance main airflow channel. The three work together to achieve rapid and directional heat and moisture removal, completely solving the technical contradiction between breathability and support in traditional sponge materials. At the same time, combined with the slow rebound characteristics of the density range, the silicone rubber sponge layer 3 can provide a durable and stable base support for the entire pillow, effectively preventing collapse and deformation during sleep. It also significantly improves the compressibility and ventilation efficiency of the material through its multi-level interconnected honeycomb pores, so that the pillow can maintain excellent breathability and shape recovery ability after long-term use and repeated washing, thereby greatly improving the product's comfort, durability and hygiene.

[0027] According to some embodiments of this utility model, the minimum distance between the trough 41 of the wave surface 4 and the upper surface of the memory foam layer 1 is 2-6 cm.

[0028] According to some embodiments of this utility model, the minimum distance between the wave crest 42 of the wave surface 4 and the lower surface of the silicone rubber sponge layer 3 is 2-6 cm.

[0029] This size design first ensures that the memory foam layer 1 has sufficient filling thickness in the key area of ​​neck support, effectively cushioning head and neck pressure and providing ample deformation space, avoiding insufficient support or a hard feel due to excessively thin material. At the same time, the silicone rubber sponge layer 3 within this thickness range serves as a base, providing the necessary space for its internal multi-level breathable pore structure, ensuring the integrity and stability of the air circulation channels, thereby maintaining the overall high breathability of the pillow. In addition, this uniform thickness limit allows the pillow to provide an ergonomically effective support height through the S-shaped wave surface 4 when flipped over, whether the memory foam layer 1 or the silicone rubber sponge layer 3 is facing up, achieving a balance between support function and usage flexibility, significantly improving the product's adaptability and user experience.

[0030] 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.
