Description

Technical Field

[0001] This invention relates to the field of neck support pillow technology, specifically to a polyurethane slow rebound pillow that aids sleep and supports the neck. Background Technology

[0002] Modern society's high work intensity, fierce academic competition, and complex interpersonal relationships contribute to emotional problems such as anxiety and depression, keeping the brain in a state of constant tension and directly impacting sleep quality. Irregular lifestyles, such as working overtime late into the night and excessive use of electronic devices before bed, suppress melatonin secretion, disrupt the biological clock, and interfere with sleep cycles. Chronic sleep deprivation can lead to weakened immunity and mood disorders, making the development of a pillow that effectively promotes sleep urgently needed.

[0003] Existing sleep-aid neck pillows typically use ordinary materials that fail to conform well to the curves of the neck, making it difficult to provide effective support. Furthermore, these pillows often lack breathability and comfort, easily causing users to feel stuffy or uncomfortable during sleep. In addition, some traditional pillows are made of materials that are too hard or too soft, which may increase pressure on the cervical spine, harming cervical health and even affecting sleep quality. Therefore, existing sleep-aid neck pillows still have significant room for improvement in design and function. To address this, we propose a sleep-aid neck pillow made of polyurethane slow-rebound material. Summary of the Invention

[0004] The purpose of this invention is to provide a polyurethane slow-rebound pillow that aids sleep and protects the neck, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A polyurethane slow-rebound pillow for sleep aid and neck support includes:

[0007] The slow rebound pillow core body has a head support area and a neck support area arranged sequentially along the width direction. The height of the neck support area is lower than that of the head support area, and the top surface of the slow rebound pillow core body is a streamlined arc surface that completely conforms to the physiological curvature of the human cervical spine.

[0008] The upper end of the slow rebound pillow core is evenly equipped with multiple round wooden beads, and the bottom of the slow rebound pillow core is detachably equipped with an aromatherapy sachet; the interior of the slow rebound pillow core has several interconnected ventilation channels, which are located above the aromatherapy sachet.

[0009] Furthermore, the slow-rebound pillow core body, the head support area, and the neck support area are all made of high-density polyurethane.

[0010] Furthermore, the top surface of the head support area is provided with a circular shallow concave texture, and the top surface of the neck support area is a polished curved surface.

[0011] Furthermore, the wooden beads are made of natural wood, with a smooth surface and a certain degree of hardness, which can provide a moderate massage to the head and neck and promote blood circulation.

[0012] Furthermore, the aromatherapy sachet contains a variety of carefully selected Chinese herbal ingredients, including lavender, jujube seed, cypress seed, and polygala root, which have sleep-aiding properties.

[0013] Furthermore, the ventilation channel is filled with bamboo charcoal bundles.

[0014] Furthermore, the upper and lower surfaces of the slow rebound pillow core body are both distributed with micropores that communicate with the air-permeable channel, and the micropores on the upper surface are offset from the round wooden beads.

[0015] Furthermore, the slow-rebound pillow core body is detachably covered with a skin-friendly antibacterial outer cover, the inner layer of which is a silk protein fiber layer and the outer layer is a breathable mesh layer.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention features a partitioned design of the head support area and the neck support area in the main body of the slow rebound pillow core. The head support area provides soft and comfortable head support, while the neck support area provides strong and effective neck support. This design can precisely support the neck curve, reduce cervical spine pressure, and prevent cervical strain caused by long-term sleep.

[0018] 2. The natural round wood beads installed on the upper part of the slow rebound pillow core of this invention have a smooth surface and a certain degree of hardness. They can provide a moderate massage to the head and neck during sleep, promote local blood circulation, relieve muscle tension, and further improve sleep comfort.

[0019] 3. The detachable aromatherapy sachet of this invention contains sleep-aiding Chinese herbal ingredients such as lavender, jujube seed, cypress seed and polygala. Its fragrance diffuses upward through the internal ventilation channel, which can relieve anxiety, promote melatonin secretion and improve sleep quality.

[0020] 4. The bamboo charcoal fiber bundles filled in the breathable channel of this invention not only enhance air circulation, but also have the functions of absorbing odors and regulating humidity, keeping the internal environment of the pillow fresh and dry; the micropores on the upper and lower surfaces of the slow rebound pillow core are connected to the breathable channel, and the micropores on the upper surface are staggered from the round wooden beads, which not only ensures good breathability and avoids stuffiness and discomfort during sleep, but also does not affect the massage effect of the round wooden beads.

[0027] 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.

[0028] Please see Figure 1 - Figure 5 This invention provides a polyurethane slow-rebound pillow for sleep aid and neck support, comprising:

[0029] The slow-rebound pillow core body 1 has a head support area 2 and a neck support area 3 arranged sequentially along its width. The neck support area 3 is lower than the head support area 2, and the top surface of the slow-rebound pillow core body 1 is a streamlined arc surface that perfectly conforms to the physiological curvature of the human cervical spine. The slow-rebound pillow core body 1 is used to support and bolster the head and neck, allowing the user to maintain the natural curve of the cervical spine during sleep, reducing cervical spine pressure, and improving sleep quality. The slow-rebound pillow core body 1 is made of high-density polyurethane material, which has excellent slow-rebound performance and can deform evenly according to the pressure distribution of the head and neck, thus providing a personalized support effect. The head support area 2 supports the weight of the head, and the neck support area 3 supports the weight of the neck. The head support area 2 and the neck support area 3 form a smooth transition in height, allowing the physiological curve of the head and neck to remain continuous and natural during sleep, avoiding neck muscle tension or cervical spine misalignment caused by an unreasonable pillow structure.

[0030] The upper part of the slow-rebound pillow core body 1 is evenly equipped with multiple round wooden beads 4, and the bottom of the slow-rebound pillow core body 1 is detachably equipped with an aromatherapy sachet 5. The interior of the slow-rebound pillow core body 1 has several interconnected ventilation channels 6, which are located above the aromatherapy sachet 5. The round wooden beads 4 are used to gently massage the neck muscles by rolling slightly when the user turns over or adjusts their sleeping position, promoting blood circulation in the neck and relieving neck muscle tension and stiffness caused by poor posture such as prolonged sitting and looking down. The warm texture of the natural wood also brings a comfortable tactile experience. Combined with the soothing aroma emitted by the aromatherapy sachet 5 below, the aroma diffuses evenly around the head through the ventilation channels 6, forming a dual relaxation mechanism of touch and smell, further reducing physical and mental stress during sleep and enhancing the sleep-aiding effect.

[0031] In this embodiment, preferably, the slow rebound pillow core body 1, the head support area 2, and the neck support area 3 are all made of high-density polyurethane. High-density polyurethane material not only has good elasticity and durability, but also has certain antibacterial and anti-mite properties, which can effectively ensure the health and hygiene of the sleep environment.

[0032] In this embodiment, preferably, the top surface of the head support area 2 is provided with a circular shallow concave texture to increase the friction with the hair, reduce head slippage during sleep, and improve breathability. The top surface of the neck support area 3 is a polished curved surface with a fit of more than 95% to the curvature of the cervical vertebrae. When the neck is placed, it can form a 360° wrap-around support to relieve tension in the neck and shoulder muscles.

[0033] In this embodiment, preferably, the round wooden bead 4 is made of natural wood, with a smooth surface and a certain degree of hardness, which can provide a moderate massage to the head and neck and promote blood circulation. When the human body moves, the round wooden bead 4 rolls slightly with the rotation of the head and neck, massaging acupoints such as Fengchi and Yifeng, providing a massage effect and relieving fatigue.

[0034] In this embodiment, preferably, the aromatherapy sachet 5 contains a variety of carefully selected Chinese herbal medicines, including lavender, jujube seed, cypress seed, and polygala root, which have sleep-aiding functions. Among them, the elegant aroma of lavender can soothe nervous tension, jujube seed can regulate the balance of qi and blood in the body to relieve insomnia, cypress seed is good at nourishing the heart and calming the mind, and polygala root can reduce anxiety. The synergistic effect of the multiple herbs, through the slow evaporation of the aromatherapy sachet, integrates the natural medicinal fragrance into the sleep environment, continuously acting on the human senses, helping to relax the tense body and mind, reduce symptoms such as insomnia and excessive dreaming, thereby improving the depth and quality of sleep.

[0035] In this embodiment, preferably, the ventilation channel 6 is filled with bamboo charcoal fiber bundles. The high porosity of the bamboo charcoal fiber bundles enhances air convection within the ventilation channel, allowing the herbal aroma emitted by the aromatherapy sachet 5 to be fully dispersed and evenly diffused onto the surface of the slow-rebound pillow core 1 as it passes through the channel. This ensures that the head is always surrounded by a gentle, soothing fragrance, preventing overly strong local scents from irritating the sense of smell or underly strong scents from affecting sleep. Simultaneously, the strong adsorption properties of the bamboo charcoal fiber bundles effectively absorb sweat, oil, and residual impurities from the evaporation of the aromatherapy during sleep, preventing these substances from accumulating inside the pillow and causing odors or bacterial growth, thus maintaining a comfortable sleep environment. It maintains a fresh and dry internal environment for the pillow; in addition, the far-infrared rays released by the bamboo charcoal fiber itself can penetrate into the subcutaneous tissue of the neck, gently promoting blood circulation in the neck. This works synergistically with the rolling massage of acupoints such as Fengchi and Yifeng by the wooden beads on top, further relieving discomfort such as stiff and sore neck muscles caused by prolonged sitting or looking down, and enhancing the neck protection effect; moreover, the elastic modulus of the bamboo charcoal fiber bundles is highly compatible with the polyurethane material of the slow rebound pillow core 1, and will not affect the overall slow rebound performance of the pillow. Even with long-term use, it can maintain unobstructed air channels and avoid the obstruction of fragrance diffusion or the reduction of breathability due to fiber bundle deformation.

[0036] In this embodiment, preferably, the upper and lower surfaces of the slow-rebound pillow core 1 are both distributed with micropores 7 communicating with the ventilation channels 6, and the micropores 7 on the upper surface are staggered from the wooden beads 4. This arrangement can prevent the wooden beads 4 from blocking or squeezing the micropores 7 when rolling, ensuring that the aromatherapy fragrance in the ventilation channels 6 is evenly diffused to the head and neck area through the micropores 7 on the upper surface, forming a continuous and stable olfactory relaxation environment. At the same time, the micropores 7 on the upper surface can quickly expel sweat and heat from the head during sleep, which is absorbed by the strong adsorption of the bamboo charcoal fiber bundles in the ventilation channels 6, keeping the pillow surface dry. The pillow is dry and refreshing, avoiding the sticky discomfort caused by sweat buildup. The micropores 7 on the lower surface promote air convection between the inside and outside of the pillow. On the one hand, this helps the herbal aroma of the aromatherapy sachet 5 to enter the ventilation channel 6 more smoothly, and on the other hand, it promptly removes moisture from the inside of the pillow caused by sweat evaporation or residual aromatherapy, preventing bacterial growth or odor. In addition, the staggered design of the micropores 7 and the wooden beads 4 will not interfere with the natural rolling trajectory of the wooden beads 4 as the sleeping position is adjusted, ensuring that its gentle massage effect on acupoints such as Fengchi and Yifeng is not affected, achieving a synergistic enhancement of breathability, aromatherapy and neck massage functions.

[0037] In this embodiment, preferably, the outer side of the slow-rebound pillow core 1 is detachably covered with a skin-friendly antibacterial outer cover. The inner layer of the skin-friendly antibacterial outer cover is a silk protein fiber layer, and the outer layer is a breathable mesh layer. The silk protein fiber layer has excellent skin-friendliness and natural moisturizing function. Its rich silk protein amino acids are highly homologous to the structure of the stratum corneum of human skin, and it does not cause irritation when in contact with the skin. It can form a gentle moisturizing film to relieve the dryness and tightness of the skin caused by air conditioning or heating during sleep. At the same time, the silk protein fiber itself has anti-mite and antibacterial properties, with an inhibition rate of more than 90% against common pathogenic bacteria such as Staphylococcus aureus and Candida albicans, effectively reducing the growth of bacteria on the pillow surface and reducing the risk of problems such as facial acne and neck eczema. The outer breathable mesh layer is made of finely woven cotton and linen blend material, which not only ensures good breathability and can quickly wick away sweat and heat generated by the head and neck during sleep, but also has a certain degree of elasticity, which can naturally stretch with the deformation of the slow rebound pillow core 1 without restricting its slow rebound performance; the surface of the mesh layer is treated with water repellency, so minor liquid splashes can be wiped clean quickly, preventing them from penetrating into the inner silk protein fiber layer or the pillow core, making daily cleaning and maintenance convenient.

[0038] The working principle and usage process of this invention: When using this device, the user can first put the skin-friendly antibacterial cover on the outside of the slow rebound pillow core body 1 to ensure that the silk protein fiber layer is tightly attached to the surface of the pillow core. Then, the aroma sachet 5 containing lavender, jujube seed, cypress seed and polygala root is placed in the detachable installation position at the bottom of the slow rebound pillow core body 1, so that the aroma sachet 5 is facing the entrance of the ventilation channel 6 to ensure that the fragrance enters the channel smoothly.

[0039] When sleeping, the user places their head naturally in the head support area 2 and their neck against the neck support area 3. Whether sleeping on their back or side, the normal physiological curve of the cervical spine can be maintained, avoiding excessive twisting.

[0040] When the user turns over to adjust their sleeping position, the polyurethane material of the slow-rebound pillow core 1 slowly returns to its original shape, reducing discomfort caused by turning over. The round wooden beads 4 above the neck support area 3 roll slightly with the neck movement. The warm texture and moderate hardness of the natural wood gently massage acupoints such as Fengchi and Yifeng, promoting blood circulation in the neck and relieving neck muscle stiffness caused by prolonged sitting and looking down. During this process, the herbal aroma in the aroma sachet 5 is dispersed and evenly diffused through the bamboo charcoal fiber bundles in the breathable channel 6, and released to the head and neck area through the micropores 7 on the upper surface of the slow-rebound pillow core 1 (set off from the round wooden beads 4 to avoid obstruction). The elegant aroma of lavender soothes nervous tension, jujube seed regulates the balance of qi and blood to relieve insomnia, cypress seed nourishes the heart and calms the mind, and polygala reduces anxiety. The synergistic effect of multiple aromas forms a dual relaxation mechanism of touch (round wooden bead massage) and smell, further reducing physical and mental stress and enhancing the sleep-aiding effect.

[0041] During sleep, sweat and heat from the head are quickly channeled into the breathable channels 6 through the circular shallow concave texture of the head support area 2 and the micropores 7 on the upper surface of the slow-rebound pillow core 1. The bamboo charcoal fiber bundles absorb these substances, keeping the pillow surface dry and comfortable, preventing stickiness and discomfort. The polished curved surface of the neck support area 3 maintains a consistent fit to the cervical spine, preventing cervical spine misalignment even when turning over. Meanwhile, the skin-friendly antibacterial outer layer's silk protein fiber layer is homologous to the structure of human skin's stratum corneum, causing no irritation and forming a moisturizing film to alleviate skin dryness in air-conditioned or heated environments. The outer breathable mesh layer stretches naturally with the pillow core's deformation, without restricting slow-rebound performance, and is water-repellent, allowing for quick wiping of minor liquid spills for easy daily cleaning.

[0042] The next morning, the slow-rebound pillow core 1 had slowly returned to its original shape, and the cervical spine, having maintained its natural curve throughout the night, felt neither stiff nor sore; the aroma of the scented sachet 5 remained gentle and lingering, neither too strong nor too weak due to overnight evaporation; and the sweat and impurities absorbed by the bamboo charcoal fiber bundles did not produce any odor, keeping the inside of the pillow fresh.

[0043] For routine maintenance, users can disassemble and wash the skin-friendly antibacterial outer cover. Both the silk protein fiber layer and the breathable mesh layer are easy to clean and not easily deformed. The aroma sachet 5 can be replaced regularly according to the fragrance concentration (generally every 1-2 months) to ensure the sleep-aiding effect. The bamboo charcoal fiber bundles in the breathable channel 6 can be taken out and aired for 2-3 hours to restore their adsorption properties and extend their service life. The slow rebound pillow core 1 can be wiped with a dry towel regularly to prevent liquid penetration and maintain its slow rebound performance.

[0044] Through the above usage process and maintenance methods, this sleep-aiding neck pillow can fully utilize its multiple functions, including slow rebound support, neck massage, aromatherapy for sleep, and breathability and antibacterial properties, to achieve synergistic enhancement of neck protection and sleep aid, thereby improving the user's sleep quality.
