Description

Technical Field

[0001] The utility model relates to the technical field of pillows, in particular to a sandwich pillow. Background Art

[0002] With the continuous improvement of the economic level, people's requirements for the quality of life are getting higher and higher. Pillows play an important role in people's sleep. A suitable pillow helps you sleep more soundly, but long-term use of an unsuitable pillow will cause a series of chronic strains and even develop into cervical spondylosis.

[0003] At present, the common pillow cores on the market mainly include cotton pillows, latex pillows, etc. Due to the characteristics of pure cotton fabrics, cotton pillows have poor anti-wrinkle and shape-retaining performance. The latex pillow has a large market share at present due to its breathability and the advantage of not being prone to breeding mites; however, the cost of natural latex is relatively high, and the latex pillow is prone to deformation when subjected to excessive force. After summarizing the advantages and disadvantages of the above pillows, the applicant first developed a TPE elastic pillow. For example, a patent with the application number 201820224256.4 discloses a pillow with a pressure-dispersing structure, which realizes the effects of effectively dispersing pressure, conforming to the head curve, and having good ventilation by setting an upper grid structure, a lower grid structure, thin walls, and hollow columns; however, the pillow core structure of this pillow is relatively soft and is prone to deformation during use, affecting the use. Subsequently, a utility model patent with the application number 202220621803.9 was developed, which discloses a TPE water-washable non-pressure highly breathable pillow. By setting a first grid structure layer, a second grid structure layer, a spacer layer, and a sealing edge and other structures, it conforms to the design of the human head, has good air permeability while effectively dispersing the head pressure, and improves the overall stability of the pillow. However, the manufacturing cost is relatively high, the supporting capacity still has defects, and there is a situation of deformation after the headrest. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a sandwich pillow, which enhances the supporting capacity through a wave-shaped design, making the pillow not easily deformed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The sandwich pillow includes a skin-friendly pressure-applying layer located on the upper layer, a pressure-applying and supporting layer located on the lower layer, and a supporting layer located between the two. Both upper and lower surfaces of the supporting layer are wave-shaped structures, and the surfaces of the skin-friendly pressure-applying layer and the pressure-applying and supporting layer in contact with the supporting layer are wave-shaped structures that cooperate with the supporting layer to enhance the supporting capacity and make the pillow not easily deformed.

[0007] Preferably, the skin-friendly pressure-applying layer, the pressure-applying and supporting layer, and the supporting layer are all made of polyurethane material, and the hardness of the supporting layer is greater than that of the skin-friendly pressure-applying layer and the pressure-applying and supporting layer.

[0008] Preferably, the skin-friendly pressure layer is provided with a headrest area that is recessed inward and neckrest areas on both sides of the headrest area, and the height of the neckrest areas is higher than that of the headrest area.

[0009] Preferably, the headrest area is provided with a plurality of first ventilation holes. The aperture of the first ventilation hole located at the center is larger than that of the first ventilation holes located on both sides, and the aperture of the first ventilation holes gradually decreases from the center to both sides.

[0010] Preferably, the shape of the first ventilation holes is rhombic.

[0011] Preferably, second ventilation holes are provided at the relative positions of the support layer and the pressure-bearing support layer with respect to the first ventilation holes to achieve high breathability of the pillow.

[0012] Preferably, the shape and aperture of the second ventilation holes correspond to those of the first ventilation holes.

[0013] Preferably, a sandwich cavity is provided inside the pressure-bearing support layer, and a pressure-bearing support member is provided inside the sandwich cavity.

[0014] Preferably, the pressure-bearing support member is a cotton core filled in the sandwich cavity.

[0015] Preferably, the pressure-bearing support member includes an elastic support member. The elastic support member has a wavy structure, and its wave crests and wave troughs correspond to the wave crests and wave troughs of the pressure-bearing support layer to disperse pressure.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The sandwich pillow of the present utility model adopts a three-layer design of upper, middle and lower layers. The upper layer and the middle layer, and the middle layer and the lower layer are connected through a wavy design. The wavy structure can disperse the gravity to more paper folds, which can enhance the bearing capacity and make the pillow not easily deformed. Description of the Drawings

[0022] In the attached drawings: 10 - skin-friendly pressure layer, 11 - headrest area, 12 - neckrest area, 13 - first ventilation hole, 20 - pressure-bearing support layer, 21 - second ventilation hole, 22 - sandwich cavity, 23 - pressure-bearing support member, 30 - support layer, 31 - second ventilation hole. Detailed implementation

[0023] Embodiment 1: A preferred embodiment of the present utility model provides a sandwich pillow, which includes a skin-friendly pressure layer 10 located on the upper layer, a pressure-bearing support layer 20 located on the lower layer, and a support layer 30 located between the two. Both the upper and lower surfaces of the support layer 30 are wavy structures. The surfaces of the skin-friendly pressure layer 10 and the pressure-bearing support layer 20 in contact with the support layer 30 are wavy structures that match the support layer 30. The wavy structure design is similar to an arch structure, which can more effectively resist external pressure and load to enhance the bearing capacity. At the same time, the wavy structure can disperse the gravity to more paper folds instead of concentrating on a single plane. This dispersion effect makes the pillow piece more stable when bearing weight and is not easily deformed or damaged.

[0024] The skin-friendly pressure layer 10, the pressure-bearing support layer 20, and the support layer 30 are all made of polyurethane material. In the polyurethane material, the wavy texture or structure can increase its compressive and tensile strength, thereby improving its bearing capacity. And the hardness of the support layer 30 is greater than that of the skin-friendly pressure layer 10 and the pressure-bearing support layer 20 to better play its supporting role.

[0025] Embodiment 2: A preferred embodiment of the present utility model provides a sandwich pillow, which is only different from the above embodiment in that: the skin-friendly pressure layer 10 is provided with an inwardly concave headrest area 11 and neckrest areas 12 located on both sides of the headrest area 11. The height of the neckrest areas 12 is higher than that of the headrest area 11. The headrest area 11 is provided with a number of first ventilation holes 13. The aperture of the first ventilation hole 13 located in the center is larger than that of the first ventilation holes 13 located on both sides, and the aperture of the first ventilation holes 13 gradually decreases from the center to both sides. The shape of the first ventilation hole 13 is a rhombus.

[0026] The rhombus hole design enables the pillow to evenly disperse the pressure to the entire pillow surface when bearing pressure instead of concentrating on a certain point or area. This design helps to reduce the local pressure on the head and neck during sleep and improve the comfort of sleep. The network structure between the rhombus holes provides good support for the pillow, which can be adaptively adjusted according to the head shapes and sleeping postures of different people to ensure that the head and neck are fully supported during sleep and avoid excessive suspension or compression.

[0027] At the same time, the rhombus hole design can also reduce the sense of compression of the pillow on the head and neck. Especially for people who like to sleep on their sides, the rhombus holes can prevent parts such as the ears and face from being compressed, improving the comfort of sleep.

[0028] A second ventilation hole 21, 31 is provided at the relative position of the support layer 30 and the pressure-bearing support layer 20 and the first ventilation hole 13. The shape and aperture of the second ventilation holes 21, 31 correspond to those of the first ventilation hole 13, so that the air circulation inside the pillow is smoother, reducing the stuffy feeling and improving the comfort of sleep. Especially in summer or for people who are prone to sweating, this design can significantly reduce the damp feeling on the head and neck and keep them dry.

[0029] Embodiment 3: A sandwich pillow is provided in a preferred embodiment of the present utility model. The difference from the above embodiment is only that: a sandwich cavity 22 is provided in the pressure-bearing support layer 20, and a pressure-bearing support member 23 is provided in the sandwich cavity 22. The pressure-bearing support member 23 is a cotton core filled in the sandwich cavity 22.

[0030] Embodiment 4: A sandwich pillow is provided in a preferred embodiment of the present utility model. The difference from the above embodiment is only that: the pressure-bearing support member 23 includes an elastic support member, and the elastic support member is made of an elastic rubber member or a silica gel member. The elastic support member is a wavy structure, and its wave crests and wave troughs correspond to the wave crests and wave troughs of the pressure-bearing support layer 20 to disperse the pressure.
