Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to pillow cores. Background Technology

[0002] Existing memory foam cut pillow cores have the following defects:

[0003] 1. Monotonous cutting design: Existing products are mostly uniform square cuts or symmetrical designs, lacking ergonomically based groove depth and spacing gradients, resulting in uneven distribution of neck support and insufficient breathability.

[0004] 2. Poor adaptability: The symmetrical structure cannot adapt to different cervical spine lengths (such as short neck and long neck users), resulting in low neck fit during sleep and easy to cause discomfort.

[0005] 3. Functional limitations: The flat design only provides a single height, making it difficult to form an ergonomic brain and neck support area, which affects sleeping posture and breathing smoothness. Utility Model Content

[0006] The purpose of this invention is to provide an ergonomic pillow core with a gradient strip groove to solve at least one of the above-mentioned technical problems.

[0007] The technical problem solved by this utility model can be achieved by the following technical solution:

[0008] An ergonomic pillow core with gradient grooves has ten grooves on its front side. The depth of the grooves gradually increases from the sides of the pillow core to the center, and the distance between two adjacent grooves decreases as they get closer to the center of the pillow core.

[0009] Preferably, the depth of the groove is 6mm to 10mm.

[0010] Preferably, the spacing between two adjacent strip grooves is 10mm to 20mm.

[0011] Preferably, the ten strip grooves, from front to back, are: the first strip groove (depth 6mm±1mm), the second strip groove (depth 6mm±1mm), the third strip groove (depth 8mm±1mm), the fourth strip groove (depth 8mm±1mm), the fifth strip groove (depth 10mm±1mm), the sixth strip groove (depth 10mm±1mm), the seventh strip groove (depth 8mm±1mm), the eighth strip groove (depth 8mm±1mm), the ninth strip groove (depth 6mm±1mm), and the tenth strip groove (depth 6mm±1mm).

[0012] Preferably, the ten strip grooves extend in the same direction as the first long side and the second long side.

[0013] Preferably, the minimum distance from the first strip groove to the first long side is 70mm ± 5mm. The minimum distance from the first strip groove to the third strip groove is 40mm ± 3mm. The minimum distance from the third strip groove to the eighth strip groove is 50mm ± 3mm. The minimum distance from the eighth strip groove to the tenth strip groove is 40mm ± 3mm. The minimum distance from the tenth strip groove to the second long side is 100mm ± 5mm.

[0014] Preferably, the thickness of the ergonomic pillow core with the gradient strip groove is 80mm±5mm, and the length of the first long side is 700mm±5mm.

[0015] Preferably, the bottom of each groove is arc-shaped, and the diameter of the arc is 5mm ± 1mm.

[0016] Preferably, the back of the ergonomic pillow core with gradient strip grooves is flat.

[0017] Preferably, the back of the ergonomic pillow core with gradient strip grooves has grooves, and the number, spacing, size and / or shape of the grooves on the back are different from those on the front.

[0018] Beneficial effects:

[0019] 1. Ergonomic optimization: The gradient cut design distributes pressure on the head while maintaining the natural curvature of the cervical spine, reducing the number of times you turn over during sleep.

[0020] 2. The difference in width of the two-sided cervical support area (70mm / 100mm) covers 95% of the adult cervical spine length range [based on Leeet et al. (2018) Asian population data (sample includes Chinese individuals) human database].

[0021] 2. Enhanced Functionality: Different cutting densities on both sides provide a dual feel of softness and firmness, allowing users to choose freely according to their needs. Gradual changes in groove depth and spacing improve breathability, increasing breathability by 30% compared to traditional block-cut designs.

[0022] 3. Highly versatile: The asymmetrical design adapts to different sleeping positions (supine / side sleeping), reducing the risk of stiff neck. Attached Figure Description

[0023] Figure 1 This is a front view of the present invention;

[0024] Figure 2 This is a side view of the present invention. Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 The ergonomic pillow core with gradient grooves has ten grooves on its front side. The depth of the grooves gradually increases from the sides to the center of the pillow core, and the distance between adjacent grooves decreases as they approach the center. This creates gradient support. Preferably, the depth of the grooves is 6mm to 10mm, and the distance between adjacent grooves is 10mm to 20mm.

[0027] Preferably, the ten strip grooves, from front to back, are: first strip groove 1 (depth 6mm±1mm), second strip groove 2 (depth 6mm±1mm), third strip groove 3 (depth 8mm±1mm), fourth strip groove 4 (depth 8mm±1mm), fifth strip groove 5 (depth 10mm±1mm), sixth strip groove 6 (depth 10mm±1mm), seventh strip groove 7 (depth 8mm±1mm), eighth strip groove 8 (depth 8mm±1mm), ninth strip groove 9 (depth 6mm±1mm), and tenth strip groove 10 (depth 6mm±1mm).

[0028] The ten grooves are preferably arranged symmetrically, but the axis of symmetry is preferably offset from the axis of symmetry of the pillow core. This results in different distances from the grooves to the two sides of the pillow core, thus accommodating people with different neck lengths. For example, the long side of the ergonomic pillow core with gradient grooves at the front is designated as the first long side, and the long side of the ergonomic pillow core with gradient grooves at the back is designated as the second long side. The extension direction of the ten grooves is the same as the extension direction of the first and second long sides. The minimum distance from the first groove 1 to the first long side is 70mm ± 5mm. The minimum distance from the first groove 1 to the third groove 3 is 40mm ± 3mm. The minimum distance from the third groove 3 to the eighth groove 8 is 50mm ± 3mm. The minimum distance from the eighth groove to the tenth groove 10 is 40mm ± 3mm. The minimum distance from the tenth groove 10 to the second long side is 100mm ± 5mm. The groove distribution is designed based on the pressure data of the human head and neck to ensure that a natural curvature of "head low and neck high" is formed when the head sinks.

[0029] Preferably, the thickness of the ergonomic pillow core with the gradient strip groove is 80mm±5mm, and the length of the first long side is 700mm±5mm.

[0030] Preferably, the bottom of each groove is arc-shaped, and the diameter of the arc is 5mm ± 1mm.

[0031] Preferably, the back of the ergonomic pillow core with gradient grooves is flat. Alternatively, the back of the ergonomic pillow core with gradient grooves has grooves, the number, spacing, size, and / or shape of which differ from the grooves on the front. This allows for different sleeping experiences on both sides of the same pillow core, balancing ergonomics and breathability. For example, the two sides can use different cutting densities, with one side being softer (high-density cutting area, i.e., ten grooves) and the other side being firmer (low-density cutting area, i.e., flat), providing two sleeping experience options.

[0032] Preferably, the ergonomic pillow core with gradient grooves has through-holes running vertically. The holes are preferably evenly spaced to improve breathability.

[0033] Preferably, the ergonomic pillow core with gradient grooves is made of high-density slow-rebound memory foam, and the grooves are precisely formed through CNC hot-pressing cutting process, with no burrs on the edges.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
