Description

Technical Field

[0001] This utility model relates to the field of home and bedding products technology, specifically an adjustable multi-layer composite pillow. Background Technology

[0002] Pillows are one of the representative items in home bedding, used as fillings for comfortable sleep. Common pillows generally consist of two parts: a pillow core and a pillowcase. The pillow core is filled with soft materials such as cotton, pearl cotton, memory foam, and latex, which cannot provide even and effective support for the head and neck, preventing the neck from fully relaxing during sleep. With the widespread use of computers and mobile phones today, as people spend more time using them, prolonged forward tilting of the neck can easily lead to neck and shoulder discomfort, and in severe cases, related diseases. Furthermore, commonly used pillows have a simple structure and limited function, lacking height and tilt adjustment, reusability, and the ability to be expanded with other functions. Summary of the Invention

[0003] This utility model solves the problems of common rigid pillows on the market, such as solid wood pillows, which are too hard and cannot fully conform to the neck; purely soft pillows, such as pearl cotton filling pillows, which cannot provide uniform and effective support for the head and neck and collapse; excessive pressure on the shoulders when sleeping on the side; the inability to adjust the height of rigid and purely soft pillows; the difficulty in placing pillow function expansion devices without protection; and the inability to reuse pillows, which aggravates environmental pollution. At the same time, it ensures normal use for people and meets their various requirements by providing an adjustable multi-layer composite pillow.

[0004] This utility model is implemented as follows: An adjustable multi-layer composite pillow, as shown in Figures 1, 2 and 3, the composite pillow adopts a multi-layer pillow core, which is composed of a shaped support pillow core (1), a flexible adjustment pillow core (2) and a pillowcase (3); the pillow adopts a high and low zone design, with the left and right sides being the side sleeping area (7) and the middle being the back sleeping area (8). The side sleeping area (7) is higher than the back sleeping area (8), forming a pillow that is low in the middle and high on both sides. The height difference between the two is smoothly transitioned by an arc curve; the multi-layer pillow core is connected by adhesive, Velcro, embedded, or pillowcase wrapping.

[0005] Furthermore, as shown in Figures 1, 4, and 5, the shaped support pillow core (1) is composed of a single layer or multiple layers of rigid or micro-deformable materials. The molding technology of the shaped support pillow core (1) is a mature existing process. Rigid materials such as wood are mechanically processed into a preset shape, bamboo is pressed into a preset shape by a mold, or ceramics are shaped and fired into a preset shape. Micro-deformable materials such as soft plastic, silicone, and polyurethane are cast into a preset shape by a mold. The middle of the shaped support pillow core (1) is a shaped supine sleeping area (18) that forms an arc support body (11) that conforms to the curvature of the human cervical spine. The height difference between the two sides of the shaped side sleeping area (17) and the middle shaped supine sleeping area (18) is a smooth curve transition, which facilitates the transition between supine and side sleeping and turning over, thereby solving the problem of neck collapse and insufficient head and neck support when people sleep supine or side. The bottom four corners of the shaped support pillow core (1) are set with an adjustment slope (12) of a certain width and are equipped with 4 A trapezoidal adjuster (13) that matches the adjustment slope (12) is used to adjust the height and tilt angle of the pillow by adjusting the position of the trapezoidal adjuster (13); the left and right shaping side sleeping areas (17) of the shaping support pillow core (1) are respectively provided with storage holes (14) for placing or installing products or equipment, and protecting the products and equipment, and providing space for the pillow to achieve more functions.

[0006] Furthermore, as shown in Figures 3, 4 and 7, the shaped support pillow core (1) has an arc support body (11) in the middle shaped supine sleeping area (18) composed of multiple curved sections that conform to the curvature of the human cervical spine. The first curved support body (111) is 30 to 100 mm long and has a radius between 60 mm and 150 mm. The second curved support body (112) is 10 mm to 50 mm long and has a radius between 30 mm and 100 mm. The third curved support body (113) is 40 mm to 120 mm long and has a radius between 100 mm and 250 mm. The length of the fourth curved support body (114) is determined by subtracting the length of the first three sections from the width of the pillow at the corresponding position.

[0007] Further, as shown in Figures 4 and 5, the trapezoidal adjuster (13) is positioned below the adjustment slopes (12) at the four corners of the bottom surface of the shaping support pillow core (1), and matches the adjustment slopes (12). That is, the trapezoidal adjuster (13) faces downward as a horizontal plane, and the surface in contact with the adjustment slopes (12) of the shaping support pillow core (1) is an inclined plane with the same slope as the adjustment slopes (12) of the shaping support pillow core (1) to ensure that the two inclined planes fit tightly together. The trapezoidal adjuster (13) is configured as a stepless adjuster (131) or a bite-type graded adjuster (132). The stepless adjuster (131) and the matching stepless adjustment slopes (121) are shown in Figure 8. As shown, the stepless adjustment slope (121) is not smoothed and retains a certain rough surface to increase the friction between the shaping support pillow core (1) and the stepless adjustment slope (121). Stepless adjustment is achieved by moving the stepless adjuster (131) along the slope direction without slipping down. The bite-type grade adjustment device (132) and the matching grade adjustment slope (122), as shown in Figure 9, adopt a semi-circular bite adjustment method. That is, the grade adjustment slope (122) set on the shaping support pillow core (1) is made into a continuous semi-circular groove, and the slope of the bite-type grade adjustment device (132) is made into a semi-circular protrusion. The two are matched, and grade adjustment is achieved by moving the bite-type grade adjustment device (132) along the slope direction.

[0008] Furthermore, the left and right shaping side sleeping areas (17) of the shaping support pillow core (1) are provided with storage holes (14), as shown in Figures 2 and 4. The storage holes (14) are used to place or install products or equipment and protect the products and equipment, providing a carrier for the pillow to achieve more functions; perfumes, fragrance bags, herbal bags, and sweat absorbents can be placed in them. The pillow's flexibility adjusts the breathability of the pillow core (2) and the air holes (24) preset in the flexible side sleeping area (27) of the flexible adjustment pillow core (2) emit odors, thereby achieving the effect of using odors.

[0009] Furthermore, the flexible adjustable pillow core (2) is shown in Figures 1, 2, 3 and 6. As shown, the flexible adjustable pillow core (2) is composed of a single layer or multiple layers of deformable and resilient soft material. The molding process of the flexible adjustable pillow core (2) is a mature existing process, such as latex and memory foam being cast into a preset shape by mold. The bottom shape of each layer of the flexible adjustable pillow core (2) matches the top shape of the fixed support pillow core (1), ensuring that the fixed support pillow core (1) and the flexible adjustable pillow core (2) fit tightly together. The flexible supine sleeping area (28) of the flexible adjustable pillow core (2) has a uniform thickness along the center line of the cervical spine direction. The flexible supine sleeping area (28) is set with symmetrical arcs on both sides with the center line of the cervical spine direction as the axis and the thickness is symmetrical. The flexible side sleeping area (27) of the flexible adjustable pillow core (2) has ventilation holes (24). The flexible side sleeping area (27) of the flexible adjustable pillow core (2) has one or more ventilation holes (24) at the positions corresponding to the two storage holes (14) on the left and right sides of the fixed support pillow core (1).

[0010] Furthermore, the bottom shape of the flexible adjustable pillow core (2) is shown in Figures 2, 3 and 6. The bottom shape of each layer of flexible adjustable pillow core (2) matches the top shape of the shaping support pillow core (1), ensuring that the shaping support pillow core (1) and the flexible adjustable pillow core (2) fit tightly together. The multiple layers of flexible adjustable pillow cores (2) can also fit tightly together to provide uniform and effective support.

[0011] Furthermore, as shown in Figures 2 and 3, the flexible adjustable pillow core (2) of each layer, the flexible supine sleeping area (28), and the arc flexible body (21) are set as arc flexible bodies (21) along the cervical spine center line and have a uniform thickness. The flexible supine sleeping area (28) is set as a symmetrical arc on both sides with the cervical spine center line as the axis and the thickness is symmetrical, so as to provide uniform support for the head and neck.

[0012] Furthermore, as shown in Figures 2 and 6, the flexible side sleeping area (27) of the flexible adjustable pillow core (2) has one or more ventilation holes (24) at positions corresponding to the two storage holes (14) on the left and right sides of the shaping support pillow core (1). When perfumes, fragrance bags, herbal bags, or sweat absorbents are placed in the storage holes (14) on both sides of the shaping support pillow core (1), the fragrance can be released through the ventilation holes (24), thereby achieving the effect of using fragrance.

[0013] Furthermore, the multi-layered pillow core connection methods are shown in Figures 1, 2, and 3. The multi-layered pillow core connection methods are as follows: adhesive bonding, Velcro fastening, embedding, and pillowcase wrapping. The multi-layered pillow core connection method does not only use one of these methods, but often combines multiple connection methods. The embedding method is divided into overall embedding and partial embedding. The pillowcase wrapping method can use multiple pillowcases or a single pillowcase.

[0014] Furthermore, the bonding method, as shown in Figures 1, 2 and 3, refers to using adhesive materials such as industrial glue, plant glue, biological glue, and double-sided tape to bond the layers of pillow core together in sequence, and then wrapping it with a pillowcase to complete the connection of the multiple structures of the pillow into a whole.

[0015] Furthermore, as shown in Figures 1, 2, and 3, the Velcro method refers to attaching each layer of pillow core together sequentially using Velcro, and then covering it with a pillowcase, thereby completing the connection of multiple structures into a whole; this method facilitates the removal, washing, and replacement of the pillow.

[0016] Furthermore, the overall embedding method, as shown in Figures 10 and 11, is a physical embedding method in which the shaped support pillow core (1) is embedded into the flexible adjustment pillow core (2). The length and width of the shaped support pillow core (1) and the middle layer flexible adjustment pillow core (201) are processed to be slightly smaller than the top layer flexible adjustment pillow core (2). The lower part of the top layer flexible adjustment pillow core (2) is hollowed out with a certain depth of cavity (26) according to the size and shape of the shaped support pillow core (1). The depth of the cavity (26) is slightly less than the sum of the heights of the shaped support pillow core (1) and the middle layer flexible adjustment pillow core (201) so that the shaped support pillow core (1) and the middle layer flexible adjustment pillow core (201) can be embedded into the flexible adjustment pillow core (2) in the vertical height direction. The exposed part of the shaped support pillow core (1) is convenient for adjusting the pillow height and tilt angle through four trapezoidal adjusters (13). Then, a pillowcase is put on to wrap it up, thereby completing the connection of the multiple structures of the pillow into a whole.

[0017] Furthermore, the local embedding method, as shown in Figures 12 and 13, is a physical embedding method in which the flexible adjustable pillow core (2) is embedded in the shaping support pillow core (1). During the shaping process, the flexible adjustable pillow core (2) has an embedding body (25) of a certain thickness protruding downwards from the storage hole (14) of the corresponding shaping support pillow core (1). By embedding the protruding embedding body (25) of the flexible adjustable pillow core (2) into the storage hole (14) of the shaping support pillow core (1), the multi-layer structure is combined together, and then a pillowcase is put on to wrap it, thereby completing the connection of the multi-layer structure of the pillow into a whole; the multi-layer flexible adjustable pillow core (2) is embedded in the same way.

[0018] Furthermore, as shown in Figure 1, the pillowcase (3) is made of a fabric with a certain elasticity and is processed according to the shape of the pillow core. It is slightly smaller than the pillow core. After the pillow core is covered with the pillowcase (3), the pillowcase (3) has a certain shrinkage inward. The shrinkage of the pillowcase (3) restricts the relative displacement of the multiple pillow cores, thereby wrapping the multiple pillow cores into a whole pillow.

[0019] Furthermore, the shaped support pillow core (1), as shown in Figures 1, 4 and 5, is made of rigid material or micro-deformation material that is not easy to age. It is produced through standardized design and can be reused. When the flexible adjustment pillow core (2) becomes contaminated or aged and cannot be used after a long period of pillow use, it is only necessary to replace the flexible adjustment pillow core (2), thereby solving the problem of pillows being unusable and aggravating environmental pollution.

Detailed Implementation

[0022] Example 1

[0023] The product of this utility model is an adjustable double-layer composite pillow with a lower layer of solid wood and an upper layer of latex, as shown in Figure 1. Figure 2As shown in Figure 3, the composite pillow adopts a double-layer structure pillow core, which is composed of a solid wood shaped support pillow core (1), a latex flexible adjustment pillow core (2), and a pure cotton pillowcase (3). The pillow adopts a high-low zone design, with the left and right sides being the side sleeping area (7) and the middle being the back sleeping area (8). The side sleeping area (7) is higher than the back sleeping area (8), forming a pillow that is low in the middle and high on both sides. The height difference between the two is smoothly transitioned by an arc curve. The double-layer structure pillow core is connected by a combination of partial embedding and pillowcase wrapping.

[0024] Furthermore, as shown in Figures 1, 4, and 5, the solid wood shaped support pillow core (1) is composed of a single layer of solid wood boards, which are mechanically processed into a preset shape. The middle of the solid wood shaped support pillow core (1) is a shaped supine sleeping area (18) that forms an arc support body (11) that conforms to the curvature of the human cervical spine. The height difference between the two sides of the shaped side sleeping area (17) and the middle shaped supine sleeping area (18) is a smooth curve transition, which facilitates the transition between supine and side sleeping and turning over, thereby solving the problem of neck collapse and insufficient head and neck support when people sleep on their back or side. The bottom four corners of the solid wood shaped support pillow core (1) are set with an adjustment slope (12) of a certain width, and are equipped with 4 A trapezoidal adjuster (13) that matches the adjustment slope (12) is used to adjust the height and tilt angle of the pillow by adjusting the position of the trapezoidal adjuster (13); the solid wood shaping support pillow core (1) has storage holes (14) in the left and right shaping side sleeping areas (17) respectively, which are used to place or install products or equipment and protect the products and equipment, and provide space for the pillow to achieve more functions; the solid wood shaping support pillow core (1) has positioning holes in the middle shaping supine sleeping area (18) for positioning when installing the upper and lower structure.

[0025] Furthermore, the solid wood molded support pillow core (1) has an arc support body (11) in the middle molded supine sleeping area (18), as shown in Figures 3, 4, and 7. The arc support body (11) in the middle molded supine sleeping area (18) is composed of multiple curved bodies to form a support body that conforms to the curvature of the human cervical spine. The first curved support body (111) is 70mm long and has a radius of 120mm; the second curved support body (112) is 20mm long and has a radius of 60mm; the third curved support body (113) is 80mm long and has a radius of 200mm; and the fourth curved support body (114) is 150mm long.

[0026] Furthermore, the trapezoidal adjuster (13) is shown in Figures 4 and 5. As shown, the trapezoidal adjuster (13) is set below the adjustment slope (12) at the four corners of the bottom surface of the solid wood shaped support pillow core (1) and matches the adjustment slope (12). That is, the trapezoidal adjuster (13) is horizontal when it faces down, and the surface that connects with the adjustment slope (12) of the shaped support pillow core (1) is a slope. The slope is the same as the slope of the adjustment slope (12) of the shaped support pillow core (1) to ensure that the two slopes fit tightly together. The trapezoidal adjuster (13) is set as a stepless adjuster (131). The stepless adjuster (131) and the stepless adjustment slope (121) that it matches are shown in Figure 8. The stepless adjustment slope (121) is not smooth and retains a certain rough surface to increase the friction between the shaped support pillow core (1) and the stepless adjustment slope (121). Stepless adjustment is achieved by moving the stepless adjuster (131) along the slope direction without sliding down.

[0027] Furthermore, the solid wood shaped support pillow core (1) has storage holes (14) in the left and right shaped side sleeping areas (17), such as... Figure 2 As shown in Figure 4, the storage hole (14) is used to place or install products or equipment and to protect the products and equipment, providing a carrier for the pillow to achieve more functions; perfumes, fragrance bags, herbal bags, and sweat absorbents can be placed in the pillow core (2) to release odors by utilizing the breathability of the latex flexible adjustable pillow core (2) and the air holes (24) preset in the flexible side sleeping area (27) of the latex flexible adjustable pillow core (2); when the upper and lower structure is assembled, the storage holes (14) in the left and right side sleeping areas (17) of the solid wood shaped support pillow core (1) and the positioning holes in the middle shaped supine sleeping area (18) are used for accurate positioning and fixation.

[0028] Furthermore, as shown in Figures 2 and 6, the latex flexible adjustable pillow core (2) is made of a single layer of latex material cast into a preset shape using a mold; the bottom shape of the latex flexible adjustable pillow core (2) matches the top shape of the solid wood shaped support pillow core (1), ensuring that the solid wood shaped support pillow core (1) and the latex flexible adjustable pillow core (2) fit tightly together; the flexible body (21) of the flexible supine sleeping area (28) of the latex flexible adjustable pillow core (2) has a uniform thickness along the center line of the cervical spine direction, and the flexible supine sleeping area (28) is oriented towards the cervical spine direction. The latex flexible adjustable pillow core (2) has a flexible side sleeping area (27) with ventilation holes (24). The flexible side sleeping area (27) of the latex flexible adjustable pillow core (2) has a single ventilation hole (24) at the position corresponding to the two storage holes (14) on the left and right sides of the solid wood shaped support pillow core (1). The flexible side sleeping area (27) of the latex flexible adjustable pillow core (2) has a downward protruding embedded body (25) for positioning and embedded fixation.

[0029] Furthermore, as shown in Figures 2 and 6, the bottom shape of the latex flexible adjustable pillow core (2) matches the top shape of the solid wood shaped support pillow core (1), ensuring that the solid wood shaped support pillow core (1) and the latex flexible adjustable pillow core (2) fit tightly together to provide uniform and effective support.

[0030] Furthermore, as shown in Figures 2 and 6, the flexible supine sleeping area (28) of the latex flexible adjustable pillow core (2) is set as an arc flexible body (21) along the cervical spine center line, and the thickness is uniform. The flexible supine sleeping area (28) is set as a symmetrical arc on both sides with the cervical spine center line as the axis, and the thickness is symmetrical, so as to provide uniform support for the head and neck.

[0031] Furthermore, as shown in Figures 2 and 6, the flexible side sleeping area (27) of the latex flexible adjustable pillow core (2) has a single ventilation hole (24) at a position corresponding to the two storage holes (14) on the left and right sides of the solid wood shaped support pillow core (1). When perfume, fragrance bags, herbal bags, or sweat absorbents are placed in the storage holes (14) on both sides of the solid wood shaped support pillow core (1), the fragrance is released through the ventilation hole (24), thereby achieving the effect of using fragrance.

[0032] Furthermore, the double-layer pillow core connection method is shown in Figures 1 and 2. The double-layer pillow core connection methods are as follows: adhesive bonding, partial embedding, and pillowcase wrapping. The double-layer pillow core connection method does not only use one of these methods, but more often combines multiple connection methods.

[0033] Furthermore, as shown in Figures 1 and 2, the bonding method refers to using adhesive materials such as industrial glue, plant glue, biological glue, and double-sided tape to bond the upper and lower pillow cores together, and then covering them with a pillowcase to complete the connection of the two pillow structures into a whole pillow.

[0034] Furthermore, the partial embedding method, as shown in Figures 12 and 13, is a physical embedding method in which the latex flexible adjustable pillow core (2) is partially embedded into the solid wood shaped support pillow core (1). During the shaping process, the latex flexible adjustable pillow core (2) protrudes downwards at the storage hole (14) position of the corresponding solid wood shaped support pillow core (1) to form an embedding body (25). By embedding the protruding embedding body (25) of the latex flexible adjustable pillow core (2) into the storage hole (14) of the solid wood shaped support pillow core (1), the double-layer structure is combined together, and then a pillowcase is put on to wrap it, thereby completing the connection of the double-layer structure into a whole pillow.

[0035] Furthermore, as shown in Figure 1, the pillowcase (3) is made of a fabric with a certain elasticity and is made according to the shape of the pillow core. It is slightly smaller than the pillow core. After the pillow core is covered with the pillowcase (3), the pillowcase (3) has a certain shrinkage inward. The shrinkage of the pillowcase (3) restricts the relative displacement of the double-layer pillow core, thereby wrapping the double-layer pillow core into a whole pillow.

[0036] Furthermore, the solid wood shaped support pillow core (1), as shown in Figures 1, 4 and 5, is made of wood and produced through standardized design. It can be reused. When the latex flexible adjustment pillow core (2) becomes contaminated or ages and cannot be used after long-term use of the pillow, it is only necessary to replace the latex flexible adjustment pillow core (2), thereby solving the problem of pillows being unusable and aggravating environmental pollution.

The height difference between the two is smoothly transitioned by an arc curve. The three-layer structure pillow core is connected by a combination of overall embedding and pillowcase wrapping.

[0039] Furthermore, as shown in Figures 1, 4, and 5, the solid wood shaped support pillow core (1) is composed of a single layer of solid wood boards, which are mechanically processed into a preset shape. The middle of the solid wood shaped support pillow core (1) is a shaped supine sleeping area (18) that forms an arc support body (11) that conforms to the curvature of the human cervical spine. The height difference between the two shaped side sleeping areas (17) and the middle shaped supine sleeping area (18) is a smooth curve transition, which facilitates the transition between supine and side sleeping and turning over, thereby solving the problem of neck collapse and insufficient head and neck support when people sleep on their back or side. The bottom four corners of the solid wood shaped support pillow core (1) are set with an adjustment slope (12) of a certain width, and are equipped with 4 A trapezoidal adjuster (13) that matches the adjustment slope (12) is used to adjust the height and tilt angle of the pillow by adjusting the position of the trapezoidal adjuster (13); the solid wood shaping support pillow core (1) has storage holes (14) on the left and right shaping side sleeping areas (17) respectively, which are used to place or install products or equipment, and protect the products and equipment, and provide space for the pillow to achieve more functions.

[0040] Furthermore, the solid wood molded support pillow core (1) has an arc support body (11) in the middle molded supine sleeping area (18), as shown in Figures 3, 4, 7 and 15.

The first curved support body (111) is 65mm long and has a radius of 110mm; the second curved support body (112) is 25mm long and has a radius of 65mm; the third curved support body (113) is 75mm long and has a radius of 180mm; and the fourth curved support body (114) is 160mm long.

[0041] Furthermore, as shown in Figures 4, 9, 14 and 15, the trapezoidal adjuster (13) is configured as an interlocking graded adjuster (132) that matches the graded adjustment slope (122) and is adjusted by a semi-circular interlocking method. That is, the graded adjustment slope (122) of the shaping support pillow core (1) is made into a continuous semi-circular groove, and the slope of the interlocking graded adjuster (132) is made into a semi-circular protrusion. The two match, and the graded adjustment is achieved by moving the interlocking graded adjuster (132) along the slope direction.

[0042] Furthermore, the solid wood shaped support pillow core (1) has storage holes (14) in the left and right shaped side sleeping areas (17), such as... Figure 9 As shown in Figures 11, 14, and 15, the storage hole (14) is used to place or install products or equipment and to protect the products and equipment, providing a carrier for the pillow to achieve more functions; perfumes, fragrance bags, herbal bags, and sweat absorbents can be placed there. The pillow's flexible adjustment of the breathability of the pillow core (2) and the air holes (24) preset in the flexible side sleeping area (27) of the flexible adjustment pillow core (2) can be used to release the odor, thereby achieving the effect of using the odor.

[0043] Furthermore, the memory foam flexible adjustable pillow core (2) is shown in Figures 10, 11, 14, and 15. As shown, the memory foam flexible adjustable pillow core (2) is composed of double-layer memory foam material and is cast into a preset shape by a mold; the bottom shape of each layer of memory foam flexible adjustable pillow core (2) matches the top shape of the solid wood fixed support pillow core (1) to ensure that the solid wood fixed support pillow core (1) and the memory foam flexible adjustable pillow core (2) fit tightly together; the flexible body (21) of the flexible supine sleeping area (28) of the memory foam flexible adjustable pillow core (2) has a uniform thickness along the center line of the cervical spine, and the flexible supine sleeping area (28) is set with symmetrical arcs on both sides with the center line of the cervical spine as the axis and the thickness is symmetrical; the flexible side sleeping area (27) of the memory foam flexible adjustable pillow core (2) has ventilation holes (24), and the flexible side sleeping area (27) of the memory foam flexible adjustable pillow core (2) has a single ventilation hole (24) at the position corresponding to the two storage holes (14) on the left and right sides of the solid wood fixed support pillow core (1).

[0044] Furthermore, the bottom shape of the memory foam flexible adjustable pillow core (2) is shown in Figures 10, 11, 14, and 15. The bottom shapes of the memory foam flexible adjustable pillow core (2) and the memory foam intermediate layer flexible adjustable pillow core (201) are matched with the top shape of the solid wood shaped support pillow core (1), ensuring that the solid wood shaped support pillow core (1) and the memory foam flexible adjustable pillow core (2) fit tightly together. The double-layer memory foam flexible adjustable pillow cores can also fit tightly together to provide uniform and effective support.

[0045] Furthermore, the memory foam flexible adjustable pillow core (2) has a flexible supine sleeping area (28) and an arc-shaped flexible body (21), such as... Figure 3 As shown in Figures 11 and 15, the memory foam flexible adjustable pillow core (2) and the memory foam intermediate layer flexible adjustable pillow core (201) are both set as curved flexible bodies (21) along the cervical spine center line in the flexible supine sleeping area (28), and the thickness is uniform. The flexible supine sleeping area (28) is set as a symmetrical arc on both sides with the cervical spine center line as the axis, and the thickness is symmetrical, so as to provide uniform support for the head and neck.

[0046] Furthermore, the memory foam flexible adjustable pillow core (2) has a flexible side sleeping area (27) with ventilation holes (24), as shown in Figure 10. Figure 11 As shown in Figure 15, the flexible side sleeping area (27) of the memory foam flexible adjustable pillow core (2) and the memory foam middle layer flexible adjustable pillow core (201) has a single ventilation hole (24) at the position corresponding to the two storage holes (14) on the left and right sides of the shaping support pillow core (1). When perfume, fragrance bags, herbal bags, and sweat absorbents are placed in the storage holes (14) on both sides of the shaping support pillow core (1), the fragrance is released through the ventilation hole (24), thereby achieving the effect of using fragrance.

[0047] Furthermore, the three-layer pillow core connection method is shown in Figures 10, 11, 14, and 15. The three-layer pillow core connection method is as follows: overall embedding method and pillowcase wrapping method. The three-layer pillow core connection method does not only adopt one method, but more often combines multiple connection methods.

[0048] Furthermore, the overall embedding method is shown in Figures 10, 11, 14, and 15. As shown, this is the physical embedding method of the solid wood shaped support pillow core (1) into the memory foam flexible adjustment pillow core (2). The length and width of the solid wood shaped support pillow core (1) and the memory foam intermediate layer flexible adjustment pillow core (201) are processed to be slightly smaller than the top layer memory foam flexible adjustment pillow core (2). The bottom part of the top layer memory foam flexible adjustment pillow core (2) is hollowed out with a certain depth of cavity (26) according to the size and shape of the solid wood shaped support pillow core (1). The depth of the cavity (26) is slightly less than the sum of the heights of the solid wood shaped support pillow core (1) and the memory foam intermediate layer flexible adjustment pillow core (201) so that the solid wood shaped support pillow core (1) and the memory foam intermediate layer flexible adjustment pillow core (201) can be embedded in the top layer memory foam flexible adjustment pillow core (2) in the vertical height direction. The solid wood shaped support pillow core (1) is partially exposed, which facilitates the adjustment of the pillow height and tilt angle through four interlocking grade adjustment devices (132). Then, a pillowcase is put on to cover it, thus completing the connection of the multiple structures of the pillow into a whole.

[0049] Furthermore, as shown in Figure 1, the pillowcase (3) is made of a fabric with a certain elasticity and is made according to the shape of the pillow core. It is slightly smaller than the pillow core. After the pillow core is covered with the pillowcase (3), the pillowcase (3) has a certain shrinkage inward. The shrinkage of the pillowcase (3) restricts the relative displacement of the three layers of pillow core, thereby wrapping the three layers of pillow core into a whole pillow.

[0050] Compared with existing technologies, it has the following advantages and effects.

[0051] 1. Scientifically designed zones for ergonomic fit: The concave central zone is designed for back sleeping, conforming to the natural curvature of the cervical spine, fitting the head and neck, and preventing the neck from being unsupported; the raised zones on both sides are suitable for side sleeping, supporting the head and keeping the spine level; the height difference adapts to sleeping posture, reduces turning over, and minimizes sleep interruptions.

[0052] 2. Advantages of composite materials: The lower molded pillow core provides stable support and is not easily deformed; the upper flexible material conforms to the neck and is soft and comfortable; the combination of soft and firm materials disperses pressure on the head and neck, relaxes muscles, and improves sleep.

[0053] 3. Compared to traditional pillows: stronger support and less prone to collapsing; fits the cervical spine and reduces strain; breathable and comfortable, suitable for all seasons.

[0054] 4. The lower adjuster can adjust the height and tilt angle to suit different people.

[0055] 5. The storage hole can hold spices and medicine packets, expanding its functionality.

[0056] In summary, this pillow combines composite materials and ergonomics, providing both support and comfort. It is suitable for people with neck discomfort and offers both functionality and health benefits.
