Description

Technical Field

[0001] The utility model relates to the technical field of bedding products, in particular to a 3D air cushion pillow whose height and hardness can be adjusted by inflation. Background Art

[0002] As a kind of bedding, pillow plays an extremely important role when you sleep. If you don't use a pillow when you sleep, the physiological curvature of the neck will not be maintained and guaranteed. Over time, it will pull the neck muscles, causing obvious stiffness and pain. In the long run, it may lead to cervical bone hyperplasia, facet joint dislocation and cervical spondylosis.

[0003] From a physiological point of view, the human spine is a straight line when viewed from the front, with several physiological curvatures on both sides, and is curved in an S shape when viewed from the side, and a "C" shape at the neck position, so a pillow is needed to fill the gap to keep the neck in a normal physiological curvature, provide effective all-round support for the neck, disperse the pressure on the neck, and let it relax. However, the height of the pillows made from buckwheat husks at home has not been scientifically calculated; the height and hardness of latex pillows and commercial pillows will change after washing or compression, and the cervical spine will change during this subtle change process, and gradually, stiff necks and insomnia will occur frequently, which is actually inseparable from the fact that the height and hardness of the pillow cannot be adjusted.

[0004] In addition, after using the pillow for a period of time, due to the special nature of the pillow core material, it cannot be washed at any time, resulting in the pillow core being full of dirt, looking yellow and dirty, and even breeding mites. Based on the above situation, how to adjust the height and hardness of the pillow according to the different cervical curvatures of different people during use, how to meet the requirements of cleanliness and health, and create the most comfortable sleeping experience with subtle changes are technical problems that need to be solved urgently. Utility Model Content

[0005] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0006] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a 3D air cushion pillow that can adjust the height and hardness by inflation. The height and hardness of the cervical support area can be adjusted at will through the built-in inflatable bag, giving the cervical spine a stable support, achieving the stretching of the cervical spine, helping to correct cervical problems, allowing people to fall asleep faster and sleep more deeply for a longer time, and can meet the needs of different users. The three-dimensional partition design of the 3D air cushion pillow supports the concave parts and accommodates the protruding parts, giving the neck effective support in all directions, dispersing the pressure on the neck, alleviating the troubles of stiff neck, allowing the neck to enter a relaxed state, and improving the quality of sleep. In addition, the pillow core is made of 3D material and is formed in one piece through warp knitting. While ensuring support, it improves breathability and comfort, meets the requirements of cleanliness and health, and is easy to wash.

[0007] The utility model provides a 3D air cushion pillow that can adjust the height and hardness by inflation, including an air cushion pillow, the air cushion pillow is divided into a cervical vertebra support area and a head relaxation area, the head relaxation area is divided into a brain fossa area and a peripheral support area, and the air cushion pillow also includes an inflation adjustment device. The air cushion pillow is designed according to ergonomics, the cervical vertebra support area supports the human cervical vertebra, and the head relaxation area supports the back of the human head. The height and hardness of the cervical vertebra support area can be adjusted at will through the inflation adjustment device, giving the cervical vertebra a stable support, achieving cervical vertebra stretching, helping to correct cervical vertebra problems, allowing people to fall asleep faster and have a longer deep sleep time, and can meet the needs of different users.

[0008] In some embodiments, the inflation adjustment device includes an inflatable bag, a ventilating tube and a rubber pump. The inflatable bag is placed in the cervical vertebra support area, the ventilating tube and the rubber pump are placed outside the air cushion, one end of the ventilating tube is connected to the inflatable bag, and the other end of the ventilating tube is connected to the rubber pump. The diameter of the ventilating tube near the inflatable bag is smaller than the diameter near the rubber pump. Small beads are arranged in the ventilating tube. The small beads move in the ventilating tube to prevent air leakage. The inflatable bag is inflated through the ventilating tube by squeezing the rubber pump, and the height and hardness of the inflatable bag can be adjusted at will, thereby adjusting the height and hardness of the cervical vertebra support area. At the same time, manual inflation has no mechanical noise and no electromagnetic radiation, which is more comfortable and healthy.

[0009] In some embodiments, the diameter of the beads is equal to or greater than the diameter of the ventilation tube near one end of the inflatable bag, and smaller than the diameter of the ventilation tube near one end of the rubber pump. The diameters of the two ends of the ventilation tube are different. When inflated to a suitable height and hardness, the beads in the ventilation tube are pushed toward the end near the inflatable bag to block the ventilation tube to prevent air leakage. When deflated, the beads are manually pushed out to deflate.

[0010] In some embodiments, an air leakage prevention device is provided at the connection between the ventilating tube and the rubber pump. The provision of the air leakage prevention device can further prevent the release of air in the inflatable bag and avoid the rubber pump being squeezed all the time and thus being worn out.

[0011] In some embodiments, the anti-leakage device includes a switch button. The switch button is used to control the anti-leakage device, that is, when inflating, the channel in the anti-leakage device is interconnected with the ventilation tube and the rubber pump to facilitate the inflation of the airbag. After the inflation is completed, the switch button is pressed to block the outflow of air in the ventilation tube to prevent the airbag from leaking. When deflated, the switch button is pressed again to deflate the airbag.

[0012] In some embodiments, the air cushion pillow includes a pillowcase and a pillow core, and the pillow core includes a plurality of X-shaped support structures, each of which is composed of cross-woven fiber monofilaments. The pillow core is woven from highly elastic functional fibers through X-90° cross-support, breaking through the traditional 0° support of loose fibers, effectively supporting the cervical curvature and the back of the human head.

[0013] In some embodiments, the head relaxation area of ​​the pillowcase is made of Tencel fabric, and the cervical vertebra support area of ​​the pillowcase is made of 3D mesh fabric. The partition design of the pillowcase fabric gives the head a sense of being wrapped, and there will be no pricking or foreign body stimulation during sleep.

[0014] In some embodiments, the air cushion pillow is provided with an opening for inserting the pillow core and the inflatable bag. The pillow core is placed in the pillowcase, and the inflatable bag is hidden inside the pillow core in the cervical vertebra supporting area, so the pillow core and the hidden inflatable bag are both taken out through the opening, preferably, the opening can be but not limited to a zipper.

[0015] In some embodiments, the height of the cervical vertebra support area ranges from 5 cm to 15 cm. The height-adjustable cervical vertebra support area can meet the needs of different user groups, and can also keep the neck in a normal physiological curvature, provide all-round effective support for the neck, disperse the pressure on the neck, and let it enter a relaxed state. At the same time, it can stretch the cervical spine and help correct cervical problems.

[0016] In some embodiments, the air cushion pillow is provided with a storage bag, which can store a ventilation tube and a rubber pump.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. When the user uses the pillow, the rubber pump is pressed to gradually inflate the airbag, providing uniform support to the cervical support area, which can promote relaxation and relief of the cervical spine and reduce neck pressure and fatigue. At the same time, the cervical support area can also stretch the cervical spine by gradually increasing its height and hardness, which helps to correct cervical problems.

[0019] 2. Use a rubber pump to manually inflate the airbag. Compared with the electrically inflated airbag, the manually inflated airbag not only has no mechanical noise and no electromagnetic radiation, but most importantly, the height is controllable. The user can inflate the airbag as high as he wants, ensuring safety while enjoying a comfortable sleep.

[0020] 3. The pillow adopts a three-dimensional partition design, which fits the human skeleton curve, supports the concave parts, and accommodates the convex parts. It fits closely to the natural curvature of the neck when sleeping on your back, and fits closely to the shoulders when sleeping on your side. It can not only fix the sleeping posture, relieve the trouble of stiff neck and improve the sleep quality, but also help stretch the cervical spine and the middle brain fossa area of ​​the human body, giving the head a feeling of being wrapped, allowing users to maintain deep sleep all night.

[0021] 4. The pillow core is made of 3D material, and the pillowcase uses different fabrics according to the region, which can improve breathability and comfort. At the same time, the entire pillow will not deform when washed, meeting the requirements of cleanliness and health. It is easy to wash, and the water flows through in one second, making it clean from the inside out, without fear of dirt and mites.

[0022] 5. The diameters of the two ends of the vent tube are different, and the setting of small beads and anti-leakage devices allows users to adjust the height as they wish.
