Abstract
Description
Technical Field
[0001] This utility model relates to the field of pillow technology, specifically to a comfortable sandwich pillow. Background Technology
[0002] As economic levels continue to improve, people have higher and higher demands for quality of life. Pillows play an important role in people's sleep; a suitable pillow can help you sleep more soundly, but long-term use of an unsuitable pillow can cause a series of chronic strains and even develop into cervical spondylosis.
[0003] Currently, the most common pillow cores on the market are cotton pillows and latex pillows. Cotton pillows, due to the characteristics of pure cotton fabric, have poor wrinkle resistance and shape retention. Latex pillows, on the other hand, have a large market share due to their breathability and resistance to dust mites; however, pure natural latex is expensive, and latex pillows are prone to deformation under excessive pressure. Based on the advantages and disadvantages of these pillows, the applicant previously developed a TPE elastic pillow. For example, patent application number 201820224256.4 discloses a pillow with a pressure-dispersing structure, which achieves effective pressure dispersion, conforms to the head curve, and provides good ventilation through the setting of an upper mesh structure, a lower mesh structure, thin walls, and hollow columns; however, the pillow core structure is relatively soft and easily deforms during use, affecting its usability. Subsequently, a utility model patent with application number 202220621803.9 was developed, disclosing a TPE washable pressure-free, highly breathable pillow. This pillow, through the design of a first mesh structure layer, a second mesh structure layer, partitions, and edge sealing, conforms to the human head shape, effectively dispersing head pressure while providing good breathability and improving the overall stability of the pillow. However, this increased manufacturing cost, and its support capacity still had shortcomings, with deformation occurring after using the pillow. Meanwhile, the applicant had previously applied for a sandwich pillow with application number 202421814063.6, but it suffered from relative sliding between the upper, middle, and lower layers, affecting comfort. Therefore, the applicant further developed a comfortable sandwich pillow. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a comfortable sandwich pillow. The comfortable sandwich pillow enhances the support capacity through a wave-shaped design, making the pillow less prone to deformation, and the upper, middle and lower layers are less likely to slide relative to each other, thus improving comfort.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The comfortable sandwich pillow includes an upper skin-friendly pressure layer, a lower pressure support layer, and a support layer between the two. The support layer has a wave-shaped structure on both the upper and lower surfaces. Both the skin-friendly pressure layer and the pressure support layer include a wave-shaped central body and connecting parts at both ends of the central body. The central body and the wave-shaped structure of the support layer make contact with each other. The connecting parts of the skin-friendly pressure layer and the connecting parts of the pressure support layer are positioned opposite each other to wrap around the support layer and enhance the support capacity, making the pillow less prone to deformation and improving comfort.
[0007] Preferably, the skin-friendly pressure layer, the pressure support layer, and the support layer are all made of polyurethane material, and the hardness of the support layer is greater than that of the skin-friendly pressure layer and the pressure support layer.
[0008] Preferably, the two ends of the support layer are arc-shaped, and the connecting part of the skin-friendly pressure layer and the connecting part of the pressure support layer are bonded and fixed to form a shape that matches the two ends of the support layer, so as to completely wrap the support layer.
[0009] Preferably, the skin-friendly pressure layer has an inwardly recessed headrest area and a neck pillow area located on both sides of the headrest area, with the neck pillow area being higher than the headrest area.
[0010] Preferably, the radius of the arc end of the support layer near one neck pillow area is smaller than the radius of the arc end of the support layer on the other side.
[0011] Preferably, the headrest area is provided with a plurality of first ventilation holes, the diameter of the first ventilation hole located in the center is larger than the diameter of the first ventilation holes located on both sides, and the diameter of the first ventilation holes decreases sequentially from the center to both sides; the support layer and the pressure support layer are provided with second ventilation holes at the relative positions of the first ventilation holes to achieve high breathability of the pillow.
[0012] Preferably, the shape and diameter of the second vent hole correspond to those of the first vent hole.
[0013] Preferably, the pressure-bearing support layer has a sandwich cavity, and the sandwich cavity has a pressure-bearing support member.
[0014] Preferably, the pressure support is a cotton core filled in the sandwich cavity.
[0015] Preferably, the pressure support includes an elastic support, which has a wave-shaped structure, with its crests and troughs corresponding to the crests and troughs of the pressure support layer to disperse pressure.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model of a comfortable sandwich pillow adopts a three-layer design, with the upper and middle layers, as well as the middle and lower layers, connected by a wave-shaped design. The wave-shaped structure can distribute the weight to more paper folds, which can enhance the support and make the pillow less prone to deformation. At the same time, the wrap-around design of the connecting part makes it less likely for the upper, middle and lower layers to slide relative to each other, improving comfort.

Detailed Implementation
[0024] Example 1: A preferred embodiment of this utility model provides a comfortable sandwich pillow, including an upper skin-friendly pressure layer 10, a lower pressure support layer 20, and a support layer 30 between the two. The upper and lower surfaces of the support layer 30 are both wavy structures. Both the skin-friendly pressure layer 10 and the pressure support layer 20 include a wavy central body 11 and connecting portions 12 at both ends of the central body 11. The central body 11 and the wavy structure of the support layer 30 are in contact. The connecting portions 12 of the skin-friendly pressure layer 10 and the connecting portions 12 of the pressure support layer 20 are arranged opposite to each other to wrap the support layer 30 and enhance the support capacity, making the pillow less prone to deformation and improving comfort.
[0025] The wave-shaped structural design is similar to an arch structure, which can more effectively resist external pressure and load to enhance the support capacity. At the same time, the wave-shaped structure can distribute the weight to more paper folds rather than concentrate it on a single plane. This dispersion effect makes the pillow more stable when bearing weight and less prone to deformation or damage.
[0026] The skin-friendly pressure-applying layer 10, the pressure-supporting layer 20, and the support layer 30 are all made of polyurethane. In polyurethane, the wavy texture or structure can increase its compressive and tensile strength, thereby improving its support capacity. Furthermore, the support layer 30 has a higher hardness than the skin-friendly pressure-applying layer 10 and the pressure-supporting layer 20, thus providing better support.
[0027] Example 2: A preferred embodiment of this utility model provides a comfortable sandwich pillow, which differs from the above embodiment only in that: the two ends of the support layer 30 are arc-shaped, and the connecting part 12 of the skin-friendly pressure layer 10 and the connecting part 12 of the pressure support layer 20 are relatively bonded and fixed to form a shape that matches the two ends of the support layer 30, so as to completely wrap the support layer 30 and solve the problem of relative sliding between the upper, middle and lower layers.
[0028] The skin-friendly pressure layer 10 has an inwardly recessed headrest area 13 and neck pillow areas 14 located on both sides of the headrest area 13. The height of the neck pillow area 14 is higher than that of the headrest area 13. The radius of the arc end of the support layer 30 near one of the neck pillow areas 14 is smaller than the radius of the arc end of the other support layer 30, so as to adapt to the headrest needs and improve the comfort of the pillow.
[0029] Example 3: A preferred embodiment of this utility model provides a comfortable sandwich pillow, which differs from the above embodiment only in that: the headrest area 13 is provided with a plurality of first ventilation holes 15, the diameter of the first ventilation hole 15 located in the center is larger than the diameter of the first ventilation holes 15 located on both sides, and the diameter of the first ventilation holes 15 decreases sequentially from the center to both sides; the support layer 30 and the pressure support layer 20 are provided with second ventilation holes 21 at the relative positions of the first ventilation holes 15 to achieve high breathability of the pillow.
[0030] The shape and diameter of the second vent 21 correspond to the first vent 15, which makes the air circulation inside the pillow smoother, reduces stuffiness, and improves sleep comfort. Especially in summer or for people who sweat easily, this design can significantly reduce the dampness of the head and neck and keep them dry.
[0031] The first ventilation hole 13 and the second ventilation hole 21 are rhomboid in shape. This rhomboid design allows the pillow to distribute pressure evenly across the entire surface, rather than concentrating it at a single point or area. This design helps reduce localized pressure on the head and neck during sleep, improving comfort. The mesh structure between the rhomboid holes provides excellent support, adapting to different head shapes and sleeping positions to ensure adequate support for the head and neck, preventing excessive unsupported or compressed areas. Furthermore, the rhomboid design reduces pressure on the head and neck, especially beneficial for those who prefer to sleep on their side, preventing pressure on the ears and face and enhancing sleep comfort.
[0032] Example 4: A preferred embodiment of the present invention provides a comfortable sandwich pillow, which differs from the above embodiments only in that: the pressure support layer 20 is provided with a sandwich cavity 22, and the sandwich cavity 22 is provided with a pressure support member 23, wherein the pressure support member 23 is a cotton core filled in the sandwich cavity 22.
[0033] Example 5: A preferred embodiment of this utility model provides a comfortable sandwich pillow, which differs from the above embodiments only in that: the pressure support member 23 includes an elastic support member, which is made of elastic rubber or silicone. The elastic support member has a wave-shaped structure, and its crests and troughs correspond to the crests and troughs of the pressure support layer 20 to disperse pressure.
[0034] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
