[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] Please refer to Figures 1 to 5 As shown in this embodiment, a pillow is provided, including: a pillow body 101, with a C-shaped pillow tongue 102 on one side; the height of the C-shaped pillow tongue 102 is higher than that of the pillow body 101; the C-shaped pillow tongue 102 and the pillow body 101 form a C-shaped groove 103; and a recessed structure 104 is provided in the middle of the pillow body 101. In use, the user's head can be positioned at the recessed structure 104, and the neck can be positioned at the C-shaped pillow tongue 102 or on the side opposite to the C-shaped pillow tongue 102. This ergonomic design, with the head positioned at the recessed structure 104, allows the neck to be supported by the edge of the recessed structure 104 or by the C-shaped pillow tongue 102, preventing the head from resting on the pillow while the neck is unsupported, thus providing a more comfortable user experience. Some users who prefer lower neck support can place the C-shaped pillow tongue 102 on top of their head, while others who prefer a higher pillow position can place it at the neck position, providing different height and user experiences through different placements. This pillow addresses the shortcomings of traditional pillows in terms of firmness adjustment and sleep comfort through adjustable firmness and ergonomic design. It provides better support and comfort based on individual consumer needs, improves sleeping posture, and ultimately enhances sleep quality.

[0030] In this embodiment, a rod pillow 105 is also included, which is adapted to the C-shaped groove 103; the rod pillow 105 is embedded in the C-shaped groove 103 or is independent of the C-shaped groove 103; preferably, the length of the rod pillow 105 is less than or equal to the length of the C-shaped groove 103, such as... Figures 2 to 4As shown, its length can be slightly shorter than the length of the C-shaped groove 103, allowing the C-shaped groove 103 to completely enclose the pillow 105. The pillow 105 is cylindrical and serves as an independent auxiliary component, which can be inserted into or removed from the C-shaped groove 103. The adaptive neck pillow adopts a unique C-shaped pillow tongue 102 design, in which the pillow 105 can be embedded. The height and firmness of the pillow can be flexibly adjusted according to the cervical curvature, shoulder width, and sleeping habits of different individuals. This design not only enhances the pillow's adaptability, allowing it to meet the comfort needs of more people, but also effectively improves cervical spine support, helping to relieve fatigue and improve sleep quality. The innovative C-shaped pillow tongue structure extends forward when the user lies down, providing traction to the cervical spine and providing a stretching effect. When used by different individuals, the curvature of the pillow tongue automatically adjusts according to the pressure on the neck, thus better conforming to the cervical spine curve and improving comfort and support.

[0031] Example 2

[0032] Please refer to Figure 3 and Figure 4 A pillow, wherein the pillow body 101 is filled with slow-rebound memory foam. The aforementioned slow-rebound memory foam (also known as memory sponge or space foam) is a polyurethane polymer material with viscoelastic properties. Its core characteristic is that it can deform according to temperature and pressure, slowly returning to its original shape, achieving uniform pressure distribution. Using this slow-rebound memory foam as filling for the pillow body 101 allows it to slowly deform with the curves of the human body under pressure, conforming to the body's contours; after the pressure is removed, it gradually returns to its original shape, rather than rebounding instantly; the slow-rebound memory foam, through its open-cell structure, distributes localized pressure across the entire contact surface, reducing the risk of stiff neck.

[0033] In a preferred embodiment, the pillow 105 is a cloth cover filled with high-resilience memory foam. High-resilience memory foam (also known as fast-rebound memory foam) is a polyurethane polymer with an open-cell structure. While also belonging to the memory foam category, it differs fundamentally from the ordinary high-resilience sponge (polyether polyol) used in traditional pillows. This application demonstrates rapid rebound capability, meaning it quickly returns to its original shape after compression (rebound time significantly shorter than slow-rebound memory foam), providing immediate support. It effectively maintains the physiological curvature of the human body (such as the cervical spine) and reduces localized pressure points. Furthermore, the open structure of this material promotes air circulation and inhibits mite growth.

[0034] In a preferred embodiment, when the C-shaped groove 103 is empty, the height of the C-shaped pillow tongue 102 is 125mm; when the rod pillow 105 is inserted into the C-shaped groove 103, the height of the C-shaped pillow tongue 102 is 130mm~160mm.

[0035] Furthermore, the width of the C-shaped pillow tongue 102 is 140mm~165mm.

[0036] It should be noted that the aforementioned pillow 105 can also have a multi-layered nested structure. For example, the outermost layer is cotton cloth, the middle layer can be filled with a sponge layer, and the center is filled with a harder material. Alternatively, the center can be filled with a bag-shaped or hollow cylindrical object. Natural fragrances and natural sleep-aiding materials, such as lavender, can also be filled inside the bag-shaped or hollow cylindrical object to help with sleep and provide a certain fragrance.

[0037] The pillow's tongue structure features a C-shaped design with a degree of active adjustment. The tongue 102 deforms or shifts appropriately based on neck length and pressure, automatically filling the gap between the neck and the pillow. The independently detachable support rod structure 105 provides support and adjustment. The rod 105 has a memory foam rod embedded in the inner pocket of the fabric cover, allowing for quick replacement and fixation. Compared to the slow rebound of larger pillows, the support rod uses high-resilience memory foam. By adjusting the foaming coefficient of the memory foam, the rod offers three firmness options: soft, medium, and firm, providing better traction for different users.

[0038] The pillow body is made of 101 material (i.e., the large pillow), with slow-rebound memory foam inside, providing a softer and more comprehensive wrapping. The large pillow surface is soft for better comfort, while the small round rods are firmer to provide better support for the spine.

[0039] Specifically, the hardness of memory foam can be controlled by adjusting the foaming coefficient. For example, the isocyanate index (>1.05) increases the crosslinking density, raising the material hardness to 70D (hard) 6; decreasing it to 0.95-1.0 results in a soft (35-45D) 67. The polyether polyol ratio (POL / POP) also plays a role: a higher POL ratio (e.g., 75 / 25) results in greater hardness; a medium hardness typically uses a 60 / 40 ratio 6.

[0040] The above memory foam has the following cell structure: micropores smaller than 0.5mm account for more than 60%, which enhances support; coarse pores of 1.0-1.2mm are the main components, which improves fit.

[0041] Among them, the hard material (POL / POP=75 / 25) with a density of 60kg / m³; the medium hard material (60 / 40 ratio) with a density of 50kg / m³, balances pressure dispersion; and the soft material (POL / POP=50 / 50) with a density of 35kg / m³, reduces neck pressure.

[0042] As a high-top pillow, the 102-shaped tongue provides strong support for people with spinal problems, keeping the cervical spine horizontal and straight when sleeping on the side, without pressure on the shoulders, and allowing for smoother breathing. The small round stick-shaped pillow 105 serves as a supplementary adjustment. As a low-top pillow, it allows for a comfortable slight tilt of the head when sleeping on the back, with the chin naturally tucked in to avoid airway compression.

[0043] It should be noted that the aforementioned rod pillow 105 can also be replaced with a column of other materials of different sizes, such as a wooden stick or bamboo tube, or it can be replaced with a more rigid material according to the user's actual needs and preferences.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
