Abstract
Description
Technical Field
[0001] This utility model relates to the field of home furnishing technology, and in particular to a 3D-printed layered support cervical pillow. Background Technology
[0002] With changing modern lifestyles, prolonged desk work and use of electronic devices have led to an increasing prevalence of cervical spine problems. Traditional cervical pillows often employ a filled structure, resulting in uneven support and an inability to precisely conform to the physiological curvature of the cervical spine. Furthermore, their layered support structure design is often simplistic, failing to simultaneously meet the pressure relief needs of different areas. In addition, the inner core of traditional pillows is usually a single, non-removable piece, requiring complete soaking for cleaning and maintenance. This not only easily deforms the support structure but can also lead to bacterial growth due to incomplete cleaning, affecting hygiene and comfort. Existing technologies suffer from two main problems: First, the support structure of traditional cervical pillows cannot provide differentiated support based on ergonomics, making it difficult to effectively distribute head pressure and maintain the natural curvature of the cervical spine, resulting in poor cervical fatigue relief. Second, traditional pillows have poor disassembly capabilities, making internal structure maintenance and replacement inconvenient. Long-term use can lead to structural aging or hygiene problems. Therefore, a 3D-printed layered support cervical pillow is needed to address these issues. Utility Model Content

[0024] Please see Figure 1-4 This utility model provides a technical solution:
[0025] A 3D-printed layered support cervical pillow includes a pillowcase 1, a decorative layer 3, a 3D-printed inner frame 4, hollow tension ribs 5, an inclined support frame 6, a low-support decompression layer 7, a first high-support side decompression layer 8, a cervical spine targeted support layer 9, and a second high-support side decompression layer 10. The decorative layer 3 is placed on the pillowcase 1, the 3D-printed inner frame 4 is located inside the pillowcase 1, the hollow tension ribs 5 are connected to the 3D-printed inner frame 4, and the hollow tension ribs 5 are provided with node reinforcement blocks 51. The inclined support frame 6 is connected to the 3D-printed inner frame 4, and the low-support decompression layer 7, the first high-support side decompression layer 8, the cervical spine targeted support layer 9, and the second high-support side decompression layer 10 are sequentially distributed on the 3D-printed inner frame 4.
[0026] In this embodiment, the pillowcase 1 is provided with a zipper head 2 for opening and closing the pillowcase 1. The zipper head 2 is connected to the pillowcase 1 to facilitate maintenance and replacement of the internal structure of the pillowcase 1. The decorative layer 3 is fixed to the outer surface of the pillowcase 1 by a bonding method. The 3D printed inner skeleton 4 is an integral 3D printed structure. The hollow tension ribs 5 are integrally printed with the 3D printed inner skeleton 4. The hollow tension ribs 5 are distributed in a honeycomb mesh structure. The 3D printed inner skeleton 4 is an integral 3D printed structure. The hollow tension ribs 5 are integrally printed with the 3D printed inner skeleton 4. The hollow tension ribs 5 are distributed in a honeycomb mesh structure. Node reinforcement block 51 The 3D printed inner skeleton 4 is set at the node position of the hollow tension rib 5, and the spacing between adjacent hollow tension ribs 5 is 8mm. The first high support side decompression layer 8 and the second high support side decompression layer 10 are symmetrically distributed. The cervical spine targeted support layer 9 is located between the first high support side decompression layer 8 and the second high support side decompression layer 10. The low support decompression layer 7 is located on the left side of the first high support side decompression layer 8, the cervical spine targeted support layer 9 and the second high support side decompression layer 10. The top contour of the 3D printed inner skeleton 4 is a stepped curved surface with the left side lower and the right side higher. The height difference between the left horizontal plane and the right horizontal plane of the 3D printed inner skeleton 4 is 5cm. The inclination angle of the transition slope of the 3D printed inner skeleton 4 is 15°.
[0027] Through the above scheme: This 3D-printed layered support cervical pillow uses a 3D-printed inner skeleton 4 integrally printed from flexible polymer material. Its top has a stepped curved surface profile with a 5cm height difference (left-lower-right-higher) and a 15° transition slope, which closely conforms to the physiological curvature of the human cervical spine. The hollowed-out tension ribs 5 are integrally printed with the 3D-printed inner skeleton 4 using elastic resin material to form a honeycomb mesh structure. The 8mm spacing between adjacent hollowed-out designs, combined with node reinforcement blocks 51 at the node positions, effectively disperse head pressure and enhance structural toughness. The diagonal support frames 6, equidistantly distributed along the edges of the 3D-printed inner skeleton 4, are made of high-strength resin material, further strengthening the three-dimensional support system. The low-support pressure-reducing layer 7, the symmetrically distributed first high-support side pressure-reducing layer 8, and the second high-support side pressure-reducing layer 10, and... The central cervical spine targeted support layer 9 uses memory foam materials of different densities to form differentiated support areas. The low-pressure relief layer 7 reduces pressure on the left side, while the side pressure relief layers 8 and 10 relieve shoulder pressure. The cervical spine targeted support layer 9 precisely supports the cervical spine. Combined with the elastic tension of the inclined support frame 6 and the hollow tension ribs 5, it maintains the natural curvature of the cervical spine. The skin-friendly and breathable fabric pillowcase 1 with a zipper pull 2 is easy to remove and wash. The decorative layer 3 on the outer surface is made of wear-resistant printed fabric, which is both beautiful and practical. Through the synergistic effect of the above materials and structures, this cervical pillow can not only accurately support the cervical spine and distribute pressure according to ergonomics, effectively relieving cervical fatigue, but also has the beneficial effects of being removable and maintainable, structurally stable, and conforming to the curves of the human body, providing users with a comfortable sleep support experience.
[0028] It should be noted that this utility model is a 3D-printed layered support cervical pillow. The integrally 3D-printed inner skeleton 4 serves as the support base. Its top has a stepped curved surface profile with a left-to-right elevation, a height difference of 5cm, and a transition slope angle of 15°, which can conform to the natural curvature of the human cervical spine. The hollow tension ribs 5 have a honeycomb mesh structure and are integrally formed with the inner skeleton. The node reinforcement blocks 51 enhance the structural stability at the node positions. The hollow design with an adjacent spacing of 8mm can distribute pressure. The inclined support frame 6 is evenly distributed along the edge of the inner skeleton to further strengthen the support structure. The low support pressure relief layer 7 is located on the left side, and the first high support side pressure relief layer 8 and the second high support... The side decompression layers 10 are symmetrically distributed on both sides, and the cervical spine targeted support layer 9 is located in the middle. This layered structure can provide differentiated support for different parts: the low-support decompression layer 7 reduces pressure on the left side, the side decompression layers 8 and 10 relieve pressure on both shoulders, and the cervical spine targeted support layer 9 precisely supports the cervical spine. Together with the tension of the inclined support frame 6 and the hollow tension rib 5, a three-dimensional support system is formed to disperse head pressure and maintain the physiological curvature of the cervical spine. The decorative layer 3 is attached to the outer surface of the pillow cover 1 with a zipper head 2, which makes it convenient to open the pillow cover 1 through the zipper head 2 to maintain and replace the internal structure. The whole structure achieves decompression and support for the cervical spine through the synergistic effect of each component.
