The present disclosure relates to the technical field of pillows, particularly to a buoyancy-type pillow with a combined action of gas and liquid media.
Modern life is stressful, and the quality of sleep directly affects physical health. Therefore, people generally use pillows to support their heads during sleep, keeping the head and body in a balanced state to prevent excessive stretching or contraction of the neck and shoulder muscles. Hence, a pillow should be able to support the head, neck, and shoulders to allow the body to get proper rest and achieve good quality sleep.
The pillows available on the market are mostly filled with cotton padding, and the height and elasticity of these pillows depend on the amount of filling. Especially since everyone's body shape and habitual sleeping position are different, for example, when sleeping on the side, there is a larger gap between the side shoulder and the neck, and this area requires higher support to prevent issues like a stiff neck from occurring.
Gradually, the cotton filling inside the aforementioned pillow tends to lose its fluffiness, making it harder for heat and moisture to dissipate, which can easily lead to the growth of mold, dust mites, and other allergens within the cotton. Additionally, long-term use of a deformed pillow with poor curvature can cause the user to experience a curved cervical spine and back pain.
To address the aforementioned shortcomings, there is another type of pillow available on the market that uses elastic materials such as foam or latex. Although these materials offer better resilience compared to cotton filling materials and can provide stable support for the head and neck, they do have fixed height and elasticity. Consequently, users cannot adjust the pillow's height and elasticity to suit their individual preferences and sleeping habits.
An existing patent (application number: CN201910447583.5) discloses an adaptive intelligent comfort pillow, which has the following disadvantages: the head support device (2) is set above the water bag (8), and this arrangement still cannot make the head support device (2) fit the user's head and neck.
The present disclosure provides a buoyancy-type pillow with a combined action of gas and liquid media, ensuring the free flow of liquid within the second bladder during the user's sleep and rest, forming a shape that adapts to the head and neck to achieve an all-around buoyancy support effect, and can combine the support force of the gas to more effectively improve sleep comfort.
The buoyancy-type pillow with a combined action of gas and liquid media includes a first pillow body, a second pillow body stacked on a top of the first pillow body, and an interlayer support pad located in an inner cavity of the second bladder. The first pillow body includes a first bladder having a flat shape; an inner cavity of the first bladder is filled with gas medium; the first bladder is provided with a gas volume adjustment interface, and the gas volume adjustment interface is configured to fill the first bladder with the gas medium or to discharge the gas medium from the first bladder.

As described above, the buoyancy-type pillow with the combined action of gas and liquid media of the present disclosure has the following advantages. The buoyancy-type pillow of the present disclosure combines a water layer structure and an air layer structure. The water layer structure uses an uneven soft area to provide a comfortable sleeping sensation similar to floating on water, while the air layer structure provides sufficient support underneath. Since the liquid medium is fluid and has no fixed shape, when the liquid medium flows into the inner cavity of the second bladder, it can move to any part of the inner cavity of the second bladder, allowing the second bladder to adaptively deform according to the shape and size of the user's head and neck, thereby providing better comfort. It can fully conform to the user's head and neck, allowing them to achieve the sensation of floating on water. Users can also inject an appropriate amount of liquid through the liquid volume adjustment interface according to their own needs to find the most suitable buoyancy for themselves. The first bladder underneath can provide support for the entire pillow, and its gas volume can also be freely adjusted by the user through the gas volume adjustment interface to find the suitable height and firmness. More importantly, the innovation of the present disclosure lies in: the interlayer support pad is located in the inner cavity of the second bladder, and the interlayer support pad has a porous structure that allows the liquid medium to flow through. The interlayer support pad undergoes compressive deformation to release the liquid medium when the user's head and neck press on the second pillow, and it returns to its original shape to absorb the liquid medium when the user's head and neck are away from the second pillow. With such a setup, the interlayer support pad can provide auxiliary support, preventing the upper and lower surfaces of the second bladder from being pressed together, always maintaining the fluidity of the liquid inside the second bladder, thus effectively supporting the user's head and neck. Therefore, the buoyancy-type pillow with the combined action of gas and liquid media of the present disclosure can ensure the free flow of liquid inside the second bladder during the user's sleep and rest, forming a shape adapted to the head and neck to achieve an all-around buoyancy support effect, and can combine the support force of the gas to more effectively improve the comfort of sleep.

In the meantime, the terms “top”, “bottom”, “left”, “right”, “middle” and “one” as used in this specification are also for convenience of description, and are not intended to limit the scope of the present disclosure, and the change or adjustment of the relative relationship is considered to be within the scope of the present disclosure without substantial changes in technology.
As shown in
The first pillow body 1 comprises a first bladder 11 having a flat shape, an inner cavity of the first bladder 11 is filled with gas medium, and the first bladder 11 is provided with a gas volume adjustment interface 12, which is used to fill the first bladder 11 with the gas medium or to discharge the gas medium from the first bladder 11.
The second pillow body 2 is stacked on a top of the first pillow body 1. The second pillow body 2 includes a second bladder 21 having a flat shape. An inner cavity of the second bladder 21 is filled with liquid medium. The second bladder 21 is provided with a liquid volume adjustment interface 22, which is used to fill the second bladder 21 with the liquid medium or to discharge the liquid medium from the second bladder 21.
The interlayer support pad 3 is disposed in the inner cavity of the second bladder 21. The interlayer support pad 3 has a porous structure that allows the liquid medium to flow through. The interlayer support pad 3 undergoes compressive deformation to release the liquid medium when the user's head and neck press against the second pillow body 2. The interlayer support pad 3 returns to its original shape to absorb the liquid medium when the user's head and neck are away from the second pillow body 2.
The buoyancy-type pillow of the present disclosure combines a water layer structure and an air layer structure. The water layer structure uses uneven soft areas to provide a comfortable sleeping sensation similar to floating on water, while the air layer structure provides sufficient support underneath. Since the liquid medium (such as tap water) is fluid and has no fixed shape, when the liquid medium flows into the inner cavity of the second bladder 21, it can move to any part of the inner cavity of the second bladder 21. This allows the second bladder 21 to adaptively deform according to the shape and size of the user's head and neck, thereby providing better comfort. It can fully conform to the user's head and neck, allowing them to achieve the sensation of floating on water. Users can also fill in an appropriate amount of liquid through the liquid volume adjustment interface 22 according to their own needs, to find the most suitable buoyancy for themselves. The first bladder 11 below the second pillow body 2 can provide support for the entire pillow, and its gas volume can also be freely adjusted by the user through the gas volume adjustment interface 12, to find the suitable height and firmness for themselves.
What is more important is that the interlayer support pad 3 is located in the inner cavity of the second bladder 21, and the interlayer support pad 3 has a porous structure that allows the liquid medium to flow through. The interlayer support pad 3 undergoes compressive deformation to release the liquid medium when the user's head and neck press against the second pillow body 2, and the interlayer support pad 3 returns to its original shape to absorb the liquid medium when the user's head and neck are away from the second pillow body 2. With such a setup, the interlayer support pad 3 can provide auxiliary support force, and it can prevent the upper and lower surfaces of the second bladder 21 from being pressed together, always maintaining the fluidity of the liquid inside the second bladder 21, thus enabling the liquid to effectively support the user's head and neck.
Therefore, the buoyancy-type pillow with the combined action of gas and liquid media of the present disclosure can ensure the free flow of the liquid in the second bladder 21 when the user is sleeping and resting, forming a shape adapted to the head and neck to achieve an all-round buoyancy support effect, and can combine the support force of the gas to more effectively improve the comfort of sleep.
Additionally, compared to pure latex and sponge pillows of the same volume, most of the filling in the pillow of the present disclosure can be air and water, significantly reducing the use of chemical materials, which is not only more environmentally friendly but also reduces the shipping volume.
The first pillow body 1 and the second pillow body 2 can be fixedly connected to each other, connected by Velcro, or connected by electrostatic adsorption.
To make the second bladder 21 fit the user's head and neck more closely, the second bladder 21 includes a second bottom layer 211 and a second top layer 212. The second bottom layer 211 abuts against the first bladder 11. The second top layer 212 has an uneven undulating area 212a, and the uneven undulating area 212a fits the user's head and neck.
To reduce production costs, the interlayer support pad 3 is a sponge pad or a thick cloth pad.
To facilitate the adjustment of the gas volume or liquid volume, the buoyancy-type pillow with the combined action of gas and liquid media further includes a medium filling and releasing device 4, which can be manual or electric. The medium filling and releasing device 4 is connected to the first bladder 11 and/or the second bladder 21 through a transfer tube. The medium filling and releasing device 4 can be set separately from the first pillow body 1 and the second pillow body 2, or it can be integrated on one side of the first pillow body 1 and the second pillow body 2.
In some embodiments, the medium filling and releasing device 4 includes a liquid storage tank, a liquid suction and discharge pump, a gas suction and discharge pump, a liquid transfer tube 41, and a gas transfer tube 42. The liquid storage tank, the liquid suction and discharge pump, the liquid transfer tube 41, and the second bladder 21 are connected in sequence. The gas suction and discharge pump, the gas transfer tube 42, and the first bladder 11 are connected in sequence. The medium filling and releasing device 4 also includes a casing, which is used to accommodate the liquid storage tank, the liquid suction and discharge pump, and the gas suction and discharge pump. For example, the liquid transfer tube 41 is connected to the second bladder 21 through the liquid volume adjustment interface 22, and the gas transfer tube 42 is connected to the first bladder 11 through the gas volume adjustment interface 12.
In some embodiments, to improve the comfort brought by temperature, the medium filling and releasing device 4 includes a liquid storage tank, a liquid suction and discharge pump, a liquid transfer tube 41, a thermometer, and a heating and cooling module. The liquid storage tank, the liquid suction and discharge pump, the liquid transfer tube 41, and the second bladder 21 are connected in sequence. The thermometer is communicatively connected to the heating and cooling module to feedback the temperature information of the liquid medium to the heating and cooling module. The heating and cooling module can adjust the temperature of the liquid medium.
As shown in
To enhance the softness and fit of the top surface of the second bladder 21, the interlayer support pad 3 is provided with multiple positioning holes 31, with all the positioning holes 31 located at the edges of the interlayer support pad 3; multiple positioning connection structures 23 may be provided, with all the positioning connection structures 23 located at the edges of the second bladder 21, and each of the positioning connection structures 23 corresponds one-to-one with one of the positioning holes 31. The second top layer 212 forms the uneven undulating area 212a when each positioning connection structure 23 passes through the corresponding positioning hole 31.
