Description

Technical Field

[0001] This invention relates to the field of daily necessities technology, and in particular to a zoned adjustable pillow. Background Technology

[0002] As an indispensable sleep aid in daily life, the comfort and fit of pillows directly affect the user's sleep quality. Long-term use of ill-fitting pillows may also lead to health problems such as cervical strain and poor blood circulation in the head. With the improvement of people's living standards and the enhancement of health awareness, the functional needs of pillows are no longer limited to simple support, but rather to personalized experiences that can be flexibly adjusted according to individual conditions and adapted to different usage scenarios.

[0003] Currently, pillows on the market are generally divided into three categories based on their filling materials and adjustability: The first category is one-piece pillows with a fixed contour. The height and firmness of these pillows are not adjustable, either overall or in individual areas. Typical examples include high-resilience foam pillows and slow-rebound memory foam pillows. While these pillows provide some support, they cannot be adjusted according to individual differences such as height, cervical curvature, and sleeping posture, resulting in poor fit. Long-term use can easily lead to neck muscle tension, making them particularly unsuitable for people with sensitive necks. The second category is one-piece filled pillows. Their height and fullness can be adjusted by adding or removing filling materials, and the firmness can also be adjusted by changing the filling material. However, the overall structure lacks a zoned design, and individual areas cannot be adjusted. Typical examples include buckwheat hull pillows, crushed foam pillows, and pearl silk pillows. While these pillows offer some adjustability, the adjustment method is cumbersome, and they cannot precisely adapt to the differentiated needs of different contact areas such as the head, cervical spine, and shoulders. For example, they cannot simultaneously meet the head's need for softness and the cervical spine's need for support firmness. The third type is the simple zoned pillow, which usually has an opening on the side of the pillow. By changing or adding / removing the filling in the corresponding zone, the height and firmness can be easily adjusted. Although this type of pillow introduces the concept of zones, the number of zones is small, the zone logic is unreasonable, the adjustment method is not convenient enough, and it lacks functional design. It cannot achieve coordinated adjustment in the height and horizontal directions, making it difficult to meet the ever-changing personalized needs of users.

[0004] The aforementioned conventional pillows generally suffer from insufficient adjustability, unreasonable zone design, and limited functionality. They cannot be adjusted promptly, efficiently, or conveniently according to the user's individual conditions (such as changes in sleeping position, cervical fatigue, and seasonal changes), making it difficult to adapt to ever-changing usage needs. Long-term use of such pillows not only reduces sleep comfort but may also lead to neck pain and insomnia due to improper support and poor fit, failing to meet the modern population's demand for high-quality sleep and cervical health protection. Therefore, this invention proposes a zoned adjustable pillow that is scientifically zoned, conveniently adjustable, and fully functional, enabling precise adjustment of height and firmness, and adaptable to various usage scenarios. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing pillows, such as unreasonable zoning, inconvenient adjustment, and limited functionality. It provides a zoning adjustable pillow that achieves precise zoning of pillow position and function through a scientific zoning design. At the same time, it allows for convenient adjustment of height and firmness by filling different materials according to individual preferences for softness, resilience, and coverage. This adapts to the needs of different people, different sleeping positions, and different usage scenarios, improving sleep comfort, protecting cervical spine health, and realizing the function of multiple uses and on-demand adjustment of one pillow.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An adjustable pillow with partitions includes a pillowcase and a built-in partitioned pillow core. The pillow core adopts a layered partition structure, which is divided into 1-3 independent adjustment compartments in the height direction and 3-21 independent functional partition compartments in the horizontal direction. The pillow core is filled with organic polymer processed products, plant processed products, or granular fruit fillings. The organic polymer processed product fillings are small granular organic products such as ordinary and functional polymer soft tubes, sponges, silk balls, PP foam balls, and TPU foam balls. The plant-based fillings are wood granules, cassia seeds, tea leaves, etc.

[0007] Furthermore, the 1-3 independent adjustment compartments in the height direction are arranged from top to bottom as follows: adjustment compartment (1-layer compartment structure); adjustment compartment and cushion layer compartment (2-layer compartment structure); upper adjustment compartment, middle compartment and bottom adjustment compartment (3-layer compartment structure). The 1-3 adjustment compartments are independent of each other and each has an independent opening and closing structure.

[0008] Furthermore, in a single-layer structure, there will be 3-9 subdivided sections, filled with one or more of the following materials according to the head contact position: sponge, pearl cotton, pillow core tubing, and plants.

[0009] Furthermore, in the two-layer structure, the bottom adjustment compartment can be a single, independent cavity or a structure with 3-9 subdivided sections. When the bottom adjustment compartment is an independent cavity, it includes multiple removable thickness adjustment pads with a thickness of 0.5-2cm. When the bottom adjustment compartment has 3-9 subdivided sections, it is filled with one or more of the following: sponge, pearl cotton, 3D air fiber, and pillow core tubing. The upper adjustment compartment has 3-9 independent subdivided sections, each with its own small opening zipper, and is filled with one or more of the following: sponge, pearl cotton, 3D air fiber, pillow core tubing, and plants. By using different fillings, the hardness and function of each section can be adjusted, and quick switching between the different tactile sensations of the front and back sides can be achieved, thus achieving a dual-use purpose.

[0010] Furthermore, in the 3-layer compartment structure, the bottom adjustment compartment is either a single independent cavity or a structure with 3-9 subdivided sections, filled with one or more of the following: sponge, pearl cotton, 3D air fiber, and pillow core tubing, and equipped with multiple removable thickness adjustment pads with a thickness of 0.5-2cm. The middle compartment has 1-3 independent sections, which can be opened on three sides using a single invisible zipper, allowing the addition of one or more functional components such as massage pads, air layers, 3D air fiber, and 4D air fiber, with an adjustment range of 1-5cm. The upper adjustment compartment has 3-9 independent subdivided sections, each with an independent small opening and closing zipper, filled with one or more of the following: sponge, pearl cotton, 3D air fiber, and pillow core tubing, and can also be filled with functional polymer fillings containing plant functional ingredients, and equipped with multiple removable thickness adjustment pads with a thickness of 0.3-1.5cm.

[0011] Furthermore, the 3-21 independent functional compartments in the horizontal direction are separated by high-toughness partitions, and each compartment has an independent opening and closing structure. The specific compartment schemes include: 3 compartments (left side sleeping area, fossa area, right side sleeping area), 4 compartments (left side sleeping area, fossa area, cervical spine area, right side sleeping area), 7 compartments (lower left arm pad area, upper left covering area, lower middle cervical spine hard area, middle fossa area, upper middle head area, lower right arm pad area, upper right covering area), 9 compartments (cervical spine soft and hard dual-use area, lower left arm pad area, middle left covering area, upper left arm pad area, lower middle cervical spine hard area, middle fossa area, upper middle head area, lower right arm pad area, middle right covering area, upper right arm pad area), and subdivision schemes of 10-21 compartments.

[0012] Furthermore, the organic polymer processed product filler is a small-particle organic product such as ordinary or functional polymer soft tubes, sponges, cotton balls, PP foam balls, and TPU foam balls, and the plant-based filler is wood pellets, cassia seeds, tea leaves, etc.

[0013] Furthermore, the pillowcase is made of a breathable and skin-friendly fabric such as pure cotton, Tencel, silk, or bamboo fiber, and has ventilation holes on the surface; the opening and closing structure of each adjustment compartment adopts an invisible design, and the partition cloth is made of a high-toughness and breathable fabric.

[0014] Furthermore, the entire pillowcase and the organic polymer processed product filling are made of washable material and can be reused after washing.

[0015] The beneficial effects of this invention are as follows: 1. Scientifically designed and highly adaptable: This invention adopts a dual-zone design in both the height and horizontal directions. The height direction has 1-3 independent adjustment compartments that work together to achieve precise adjustment of the overall pillow height. The horizontal direction has 3-21 independent functional compartments that can be adjusted differently for different parts according to usage needs, adapting to the needs of different people, different sleeping positions (supine, side sleeping), and different usage scenarios (daily sleep, cervical spine rehabilitation, summer breathability, winter warmth), thus solving the problem of poor adaptability of existing pillows.

[0016] 2. Convenient and efficient adjustment, simple operation: Each section has an independent opening and closing structure. Without disassembling the entire pillow core, you can add, remove, or replace the filling material in a specific section, or add or remove the thickness adjustment pads. This allows for quick adjustment of height and firmness. The operation is convenient and can be adjusted at any time according to the user's own condition to meet the ever-changing usage needs. This solves the problem of existing pillows being cumbersome to adjust and unable to adapt in a timely manner.

[0017] 3. Comprehensive Functions, Balancing Comfort and Health: This invention uses functional polymer fillings containing plant-based ingredients, which not only provide excellent support and softness but also offer auxiliary functions such as soothing nerves, antibacterial and antimicrobial properties, and sleep aid. This enhances sleep comfort, while the precise cervical support design effectively relieves cervical fatigue and protects cervical health, solving the problem of existing pillows having limited functionality and lacking health protection.

[0018] 4. Highly practical and multi-functional: Through coordinated adjustment in both height and horizontal directions, as well as the flexible combination of functional components, this invention enables multiple uses of a single pillow. There is no need to purchase separate pillows for different scenarios, reducing usage costs. At the same time, each part of the pillow can be disassembled and washed individually, ensuring hygiene and extending its service life.

[0019] 5. Simple structure, easy to produce and promote: The overall structure of this invention is reasonably designed, without the need for complex mechanical structures or control devices. It can be produced using conventional fabrics and fillings. The production process is simple, the cost is controllable, and different partition schemes can be flexibly selected according to market demand. It is easy to scale up production and promote the market, and has good economic and social benefits. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] An adjustable pillow with partitions includes a pillowcase and a built-in partitioned pillow core. The pillow core adopts a layered partition structure, specifically divided into 1-3 independent adjustment compartments in the height direction and 3-21 independent functional compartments in the horizontal direction. Through the coordinated operation of each compartment, the height, firmness, and function can be flexibly adjusted. The pillow core is filled with functional polymer filling containing plant and other functional ingredients, taking into account both support and functionality. The method of making the functional polymer filling is as follows: the plant functional ingredients (such as lavender, cassia seed, mint, etc.) are crushed to 80-120 mesh and mixed evenly with polymer materials (such as modified sponge, 3D air fiber, pillow core tube, etc.) at a mass ratio of 1:5-1:20. After high-temperature shaping, cooling and drying, it is made into granular or sheet-like filling, which can be filled into different compartments according to needs to achieve auxiliary functions such as soothing nerves and sterilization and antibacterial properties.

[0039] Vertical partitioning design The three independent adjustment compartments in the height direction are, from top to bottom, the upper adjustment compartment 1, the middle compartment 2, and the bottom adjustment compartment 3. Each of the three adjustment compartments is independent and has its own independent opening and closing mechanism, allowing for individual adjustment while working together to achieve precise adaptation in the height direction. The specific structure is as follows: Bottom Adjustment Chamber 3: Employs either a single, independent cavity structure or a subdivided structure with 3-9 sections. The cavity is made of high-tenacity, breathable fabric to prevent filling leakage and ensure breathability. This adjustment chamber can be filled with one or more of the following filling materials: sponge (with multiple removable thickness adjustment pads ranging from 0.5-2cm), pearl cotton, 3D air fiber (with multiple removable thickness adjustment pads ranging from 0.5-2cm), or a soft pillow core tube. By increasing or decreasing the amount of filling or the number of thickness adjustment pads, the overall height of the pillow can be quickly adjusted to suit the basic support needs of people of different heights and cervical curvatures. The adjustment range is 2-8cm, and the operation is convenient without disassembling the entire pillow core.

[0040] Middle Compartment 2: Featuring 1-3 independent compartments, this section utilizes a single, concealed zipper for three-sided opening. The zipper is hidden inside the pillowcase, ensuring both comfort and aesthetics. This compartment can be equipped with one or more functional components, such as a massage pad, air layer, 3D air fiber, or 4D air fiber. This not only further adjusts the pillow's height (adjustment range 1-5cm) but also fulfills additional functional needs. For example, adding a massage pad provides neck massage and relieves muscle fatigue; adding an air layer improves breathability, making it suitable for summer use; and adding 4D air fiber enhances support, making it suitable for those with neck discomfort. The middle compartment design combines height adjustment with functional functionality, further enhancing the pillow's practicality.

[0041] Upper Adjustment Compartment 3: Features 3-9 independently subdivided sections, each with its own small zipper for adding, removing, or replacing fillings. This compartment can be filled with one or more of the following materials: sponge (with multiple removable thickness adjustment pads ranging from 0.3-1.5cm), pearl cotton, 3D air fiber (with multiple removable thickness adjustment pads ranging from 0.3-1.5cm), or a soft pillow core tube. Depending on the functional needs of different sections, functional polymer fillings containing plant-based ingredients can be added. By adjusting the amount of filling in each subdivided section or changing the filling material, precise adjustment of the firmness and coverage of different parts of the pillow's upper part can be achieved. For example, softer pearl cotton can be used for the head area to improve fit; stronger 3D air fiber can be used for the top of the head to ensure support; and functional fillings containing lavender can be used for the neck area to achieve a soothing and sleep-inducing effect.

[0042] Horizontal partition design The unit features 3-21 independent functional compartments in the horizontal direction, arranged logically according to user needs. Each compartment is an independent cavity, separated by high-strength fabric to prevent filler from mixing. Each compartment also has an independent opening and closing mechanism (invisible zipper or Velcro) for individual adjustment. For example, see attached... Figure 3 The warehouse is divided into 7 functional areas, with attached Figure 4 The warehouse is divided into 9 functional zones, with attached... Figure 5 It is divided into 10 functional zones.

[0043] The specific partitioning scheme is as follows; the number of partitions can be selected according to actual production needs: 1. Three-compartment design: The pillow is divided into three sections along its horizontal direction: left side sleeping area, head fossa area, and right side sleeping area. The left and right side sleeping areas are designed to support the head when lying on one's side and can be adjusted to the same or different heights and firmness to accommodate the different side sleeping habits of users. The head fossa area is designed to fit the head when lying on one's back and is filled with softer filling to improve comfort while maintaining the natural physiological curvature of the cervical spine.

[0044] 2. 4-Compartment Solution: The pillow is divided horizontally into four sections: left side sleeping area, fossa area, cervical spine area, and right side sleeping area. Building upon the 3-compartment solution, a cervical spine area is added specifically to support the cervical spine. It can be filled with highly supportive materials (such as 3D air fiber or soft pillow core). By adjusting the height and firmness of this area, it precisely conforms to the physiological curvature of the cervical spine, effectively relieving cervical fatigue and protecting cervical health, making it especially suitable for people with sensitive cervical spines.

[0045] 3. 7-Cavity Design: The pillow is divided horizontally into five sections: lower left arm support area, upper left cradle area, lower middle cervical spine support area, central fossa area, upper middle head support area, lower right arm support area, and upper right cradle area. This design offers more precise zoning and is suitable for various scenarios: the lower left and lower right arm support areas accommodate side-sleeping habits and are filled with soft pearl cotton; the upper left and upper right cradle areas provide lateral head support, enhancing comfort during sleep, and are filled with 3D air fibers for a supportive feel; the lower middle cervical spine support area uses highly supportive filling to precisely support the cervical spine and maintain its physiological curvature; the central fossa area is filled with soft filling that conforms to the contours of the head; and the upper middle head support area is filled with medium-firm filling to ensure stable head support.

[0046] 4. 9-Compartment Plan: Divided horizontally along the pillow into the following zones: a dual-use (soft and firm) cervical spine area, a lower left arm support area, a left middle support area, a upper left arm support area, a lower middle cervical spine hard area, a central fossa area, a upper middle head area (cervical spine soft area), a lower right arm support area, a right middle support area, and an upper right arm support area. This plan further refines the 7-compartment plan by adding a dual-use cervical spine area and left and right middle support areas to accommodate more precise user needs.

[0047] 5. 10-21 Warehouse Plan: Based on the above 9-warehouse plan, the plan further subdivides the wards according to actual needs. For example, the fossa is divided into the anterior fossa, middle fossa, and posterior fossa, and the cervical spine is divided into the upper cervical spine, middle cervical spine, and lower cervical spine. Each subdivided ward can be adjusted individually to achieve more precise adaptation. It is suitable for people with extremely high requirements for sleep quality or people with special needs (such as people recovering from cervical spine surgery).

[0048] Auxiliary structural design To further enhance the user experience, the pillowcase is made of breathable and skin-friendly fabric (such as pure cotton, Tencel, bamboo fiber, etc.). The surface of the pillowcase has ventilation holes to improve breathability and prevent stuffiness. Adjustable Velcro closures along the edges allow for adjustment to fit different head sizes, improving comfort. The zippers for each adjustment compartment are concealed inside the pillowcase to avoid skin irritation. The dividers for each section are made of high-tenacity, breathable fabric with a thickness of 0.1-0.3cm, ensuring effective separation without compromising the pillow's overall softness and breathability. Furthermore, the filling is made of washable material, and each section can be individually removed and washed to prevent bacterial growth and ensure hygiene. The functional polymer filling is reusable; simply wash and dry to restore its original properties.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
