Description

Technical Field

[0001] This utility model relates to the field of multi-zone pillow technology, and in particular to a multi-zone sleep pillow. Background Technology

[0002] A pillow is a personal item used to support the head, neck, and shoulders during sleep. Its core function is to maintain the natural physiological curvature of the cervical spine, reduce pressure on muscles and joints during sleep, and thus improve sleep comfort and quality. It typically consists of two parts: a pillowcase and a pillow filling. Pillowcases come in various materials, commonly including cotton, linen, and silk, offering both breathability and skin-friendliness. The pillow filling determines the pillow's firmness and support, with common materials including down, latex, memory foam, buckwheat hulls, and polyester fiber. Different materials have different characteristics; for example, down pillows are lightweight, soft, and elastic; latex pillows offer excellent resilience and are antibacterial and mite-proof; and memory foam pillows can mold to body temperature and pressure, conforming to the curves of the head and neck. The height and firmness of a pillow need to be adjusted according to individual sleeping habits, body type, and cervical spine condition. Pillows that are too high or too low may cause excessive bending or extension of the cervical spine, potentially leading to neck pain and stiffness with prolonged use.

[0003] Buckwheat pillows are traditional pillows filled primarily with buckwheat hulls or buckwheat hulls, offering both practicality and health benefits. Their core characteristic lies in the natural properties of the filling: buckwheat hulls are firm yet elastic, with a hollow, rhomboid structure filled with air. This allows the pillow to flexibly mold to the shape of the head and neck under pressure, closely conforming to the curves of the head and neck while maintaining a certain level of support. Unlike down pillows, which are too soft and cause the head to sink, buckwheat pillows are not inelastic enough, effectively distributing head weight and reducing strain on neck muscles. Another major advantage of buckwheat pillows is their adjustability. Users can adjust the pillow's height and firmness by increasing or decreasing the amount of buckwheat hull filling to suit different sleeping positions and personal preferences. For example, when sleeping on your back, the filling can be reduced to make the pillow lower, while when sleeping on your side, the filling can be increased for greater support.

[0004] However, existing buckwheat pillows still have significant drawbacks: Pillows that are too small only provide support for the cervical spine, lacking support for the head, and are only suitable for short-term use; pillows that are too large allow the buckwheat hulls to shift and deform during sleep, leading to unstable support for the cervical spine, or even complete loss of support, easily causing stiff neck. The root of these problems lies in the lack of a stable, zoned structure in the buckwheat filling, making it impossible to simultaneously meet the needs of softness and comfort with stable support. Utility Model Content

[0005] In order to solve the problem that existing pillows lack a stable partitioned structure for buckwheat filling, thus failing to simultaneously meet the needs of softness and comfort while providing stable support, this invention provides a multi-partitioned sleep pillow to address the problems mentioned in the background art.

[0006] The technical solution of this utility model is: A multi-zone sleep pillow includes an outer pillow with a polyester fiber cotton filling area on one side to provide a soft head wrap; and a movable buckwheat filling area on the other side, with a U-shaped depression in the middle of the movable buckwheat filling area, and a non-movable buckwheat filling area at the lowest point of the U-shaped depression, so as to maintain the shape stability when turning over in sleep and provide support for the cervical spine.

[0007] Furthermore, the outer pillow is provided with a vertical partition to separate the polyester fiber cotton filling area and the flowable buckwheat filling area.

[0008] Furthermore, the movable buckwheat filling area is detachably installed in the outer pillow using a U-shaped filling bag.

[0009] Furthermore, the non-flowing buckwheat filling area uses columnar filling bags sewn inside U-shaped filling bags.

[0010] Furthermore, the columnar filling bag is a cylindrical structure with a diameter of 60mm-120mm.

[0011] Furthermore, a latex layer is provided on top of the U-shaped filling bag.

[0012] Furthermore, the latex layer is fixed to the upper surface of the U-shaped filling bag by stitching.

[0013] Furthermore, the polyester fiber cotton filling area of ​​the outer pillow is provided with several vertical ribs connecting the upper and lower surfaces of the outer pillow.

[0014] Furthermore, the U-shaped filling bag is detachably secured inside the outer pillow via a zipper.

[0015] Furthermore, the outer pillow is equipped with a zipper for removing the U-shaped filling bag.

[0016] Compared with the prior art, the present invention has the following advantages: 1. A multi-zone sleep pillow that can form two zones: a soft sleep zone and a firm sleep zone. It includes a polyester fiber cotton filling zone, a movable buckwheat filling zone, and a non-movable buckwheat filling zone. The polyester fiber cotton filling zone is soft and conforms fully to the curves of the head and neck, providing ample support and comfort. Both the movable and non-movable buckwheat filling zones are filled with buckwheat. The movable buckwheat filling zone uses a normal buckwheat density to prevent shoulder pressure when sleeping on your side; the non-movable buckwheat filling zone uses a high-density filling process, maintaining its original shape even when turning over in sleep, providing stable support for the cervical spine and effectively preventing stiff neck.

[0017] 2. The polyester fiber cotton filling area and the movable buckwheat filling area form a U-shaped depression that conforms to the curve of the head. When sleeping on your back, the polyester fiber cotton filling area provides soft support for the head, while the movable buckwheat filling area provides non-rebound elastic support for the neck, creating support for the cervical spine and head at different levels.

[0018] 3. By dividing the pillow into sections, the flow of filling material between different areas is reduced, minimizing displacement of the filling material due to turning over during sleep, thereby maintaining the stability of support in each area of ​​the pillow.

[0019] 4. A latex layer is set on top of the U-shaped filling bag. The latex layer uses its lateral tensile force to effectively reduce the direct pressure of the head on the filling material in the flowable buckwheat filling area, avoid the filling material from flowing laterally, and ensure the stability of the flowable buckwheat filling area support.

[0022] Specific implementation method one: See Figure 1-9 As shown, a multi-zone sleep pillow, in this embodiment, includes an outer pillow 1. One side of the outer pillow 1 is provided with a polyester fiber cotton filling area 2 to provide a soft head wrap; the other side is provided with a movable buckwheat filling area 3. A U-shaped depression is formed in the middle of the movable buckwheat filling area 3, and a non-movable buckwheat filling area 4 is provided at the lowest point of the U-shaped depression, so as to maintain the shape stability when turning over in sleep and provide support for the cervical spine.

[0023] Furthermore, this invention features three sections, forming a soft pillow sleeping area and a firm pillow sleeping area. The polyester fiber filling area 2, the movable buckwheat filling area 3, and the non-movable buckwheat filling area 4 are all sewn and fixed inside the outer pillow 1. The movable buckwheat filling area 3 has a U-shaped recess in the center, the shape of which conforms to the curve of the human cervical spine, ensuring precise support for the cervical spine during sleep.

[0024] The polyester fiber filling area 2 is completely filled with soft polyester fiber cotton, with a filling height of 80mm-150mm. It conforms perfectly to the curves of the head and neck, providing ample support and soft comfort. Both the flowing buckwheat filling area 3 and the non-flowing buckwheat filling area 4 are filled with buckwheat. The flowing buckwheat filling area 3 uses a normal density of buckwheat, with a filling height of 80mm-150mm, preventing shoulder pressure when sleeping on your side. The non-flowing buckwheat filling area 4 uses a high-density filling process, with the buckwheat compacted, and a filling height of 60mm-120mm. It maintains its original shape even when turning over in sleep, providing stable support for the cervical spine and effectively preventing stiff neck. Users can choose different zones according to their individual sleeping habits.

[0025] By dividing the pillow into sections, the flow of filling material between different areas is reduced, minimizing displacement of the filling material due to turning over during sleep, thereby maintaining the stability of support in each area of ​​the pillow.

[0026] Specific Implementation Method Two: See Figure 8 As shown, the outer pillow 1 of this embodiment is provided with a vertical partition 5 for separating the polyester fiber cotton filling area 2 and the flowable buckwheat filling area 3.

[0027] Furthermore, the vertical partition 5 has the same U-shaped indentation as the flowable buckwheat filling area 3, dividing the pillow into two areas in its upper and lower structure. The vertical partition 5 is fixed to the upper and lower inner walls of the outer pillow 1 by stitching. It also serves to shape the pillow surface, preventing the filling in the center of the pillow surface from bulging and causing the pillow to become uneven.

[0028] Specific implementation method three: See Figure 3-7 As shown, in this embodiment, the movable buckwheat filling area 3 is detachably installed in the outer pillow 1 using a U-shaped filling bag 6.

[0029] Furthermore, the movable buckwheat filling area 3 adopts a modular design, with a U-shaped filling bag 6 in the form of an inner liner. This facilitates the disassembly of the movable buckwheat filling area 3 and the washing of the outer pillow 1. The U-shaped filling bag 6 is made of breathable mesh fabric and is fixed inside the outer pillow 1 by Velcro, zippers, or sewing. The U-shaped filling bag 6 is filled with buckwheat at a normal density, which helps to prevent shoulder pressure when sleeping on one's side.

[0030] Detailed Implementation Method Four: See [link] Figure 3-9 As shown, in this embodiment, the non-flowing buckwheat filling area 4 is made by sewing a columnar filling bag 7 inside a U-shaped filling bag 6.

[0031] Furthermore, the cylindrical filling bag 7 is a solid column shape. The cylindrical filling bag 7 is filled with high-density buckwheat, which supports the cylindrical filling bag 7 and keeps it in a cylindrical shape. Even when turning over and being squeezed during sleep, it still maintains its original shape, providing stable support for the cervical spine and effectively preventing stiff neck.

[0032] Specific implementation method five: See Figure 5 As shown, the cylindrical filling bag 7 in this embodiment is a cylindrical structure with a diameter of 60mm-120mm.

[0033] Specific implementation method six: See Figure 3-7 As shown, a latex layer 8 is provided on the top of the U-shaped filling bag 6 in this embodiment.

[0034] Furthermore, a latex layer 8 is provided above the U-shaped filling bag 6, and the latex layer 8 has the same shape as the upper end face of the U-shaped filling bag 6. The latex layer 8 utilizes its lateral tensile force to effectively reduce the direct pressure of the head on the filling material in the flowable buckwheat filling area 3, preventing lateral flow of the filling material and ensuring the stability of the flowable buckwheat filling area 3. Detailed implementation method seven: See Figure 3-7 As shown, in this embodiment, the latex layer 8 is fixed to the upper end face of the U-shaped filling bag 6 by sewing.

[0035] Detailed Implementation Method Eight: See also Figure 8 As shown, in this embodiment, the polyester fiber cotton filling area 2 of the outer pillow 1 is provided with several vertical ribs 9 that connect the upper and lower surfaces of the outer pillow 1.

[0036] Furthermore, the vertical ribs 9 are sewn along the length of the pillow to evenly separate the filling material in the polyester fiber cotton filling area 2, preventing the fiber cotton from shifting or clumping during use. They also connect the upper and lower surfaces of the outer pillow 1, ensuring the flatness of the pillow surface.

[0037] Detailed implementation method nine: See Figure 2-9 As shown, the U-shaped filling bag 6 of this embodiment is fixed inside the outer pillow 1 in a detachable manner by a zipper.

[0038] Detailed Implementation Method Ten: See [link] Figure 2-9 As shown, the outer pillow 1 of this embodiment is provided with a zipper 10 for removing the U-shaped filling bag 6.

[0039] Furthermore, this embodiment describes the fixing and disassembly of the U-shaped filling bag 6. To facilitate fixing the U-shaped filling bag 6, it is detachably fixed inside the outer pillow 1 via a zipper. The fixing edge of the zipper is sewn inside the outer pillow 1, and the movable edge of the zipper is sewn onto the U-shaped filling bag 6, allowing the U-shaped filling bag 6 to be fixedly removed. To facilitate the removal of the U-shaped filling bag 6, a detachable zipper 10 is provided at the front end of the outer pillow 1.
