Abstract
Description
Technical Field
[0001] This utility model relates to the field of home textiles, and more particularly to pillow cores. Background Technology
[0002] Currently available foam materials (memory foam, latex, silicone, etc.) generally adopt a single-density structure, which has the following limitations:
[0003] (1) Poor ergonomic fit: Single-density materials cannot achieve regional pressure distribution. For example, the ideal density difference between the high support area of the cervical spine and the contact area of the head in a memory foam pillow should be 15-25 kg / m². 3 However, traditional processes can only maintain ±5kg / m 3 Fluctuations in density can lead to cervical spondylosis or increased pressure on the head (refer to the "Guidelines for Ergonomic Design of Bedding" GB / T 35607-2023).
[0004] (2) The traditional mold foaming process is used to achieve different functional zones of the pillow core support height. The complex structure has low molding efficiency: multi-cavity molds require multiple injections and staged curing, which extends the production cycle by 2-3 times and increases energy consumption by 40% (refer to the 5th edition of "Polymer Materials Molding Technology"). Utility Model Content
[0005] The purpose of this invention is to provide a foamed material pillow core that can adapt to different sleeping positions by changing the pillow core compression ratio, thereby solving the above-mentioned technical problems.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 or Figure 5 A foamed pillow core that adapts to different sleeping positions by changing the pillow core indentation ratio includes a pillow core body made of foamed material, and a blind hole array on the pillow core body. The blind hole array includes at least three rows of first blind holes 3, and the number of first blind holes 3 in each row is not less than five. The first blind holes 3 located in the same row have the same depth, and the first blind holes 3 in adjacent rows have different depths. Specific Implementation Example 1
[0027] There is only one pillow core body, and the upper part of the pillow core body has an array of blind holes. The blind hole array includes seven rows of first blind holes 3, with the fourth row of first blind holes 3 having the greatest depth, and the remaining first blind holes 3 decreasing in depth as they are further away from the fourth row. Preferably, the fourth row of first blind holes 3 is located on the plane of symmetry of the pillow core body. The diameter of the first blind holes 3 gradually decreases from top to bottom, preferably in a hemispherical, arc-shaped, or curved shape, and the opening faces upward. The extension direction of the blind hole array is the same as the length or width direction of the pillow core body. Specific Implementation Example 2
[0029] There is only one pillow core, and the lower part of the pillow core has an array of blind holes. The blind hole array consists of twelve rows of first blind holes 3, with the fifth row having the greatest depth. The depth of the remaining blind holes decreases as they are further away from the fifth row. The first blind hole 3 preferably consists of a first opening and a second opening, wherein the longitudinal section of the first opening is elliptical or circular, and the second opening connects the first opening to the outside. The depth of the first openings is the same, while the depth of the second openings varies, with the maximum depth of the second opening being used as the depth of the blind hole. The extension direction of the blind hole array is the same as the length or width direction of the pillow core. Specific Implementation Example 3
[0031] There is only one pillow core body, and the upper and / or lower part of the pillow core body has an array of blind holes. The blind hole array includes at least three rows of blind holes arranged along the length of the pillow core body, and at least three rows of blind holes arranged along the width of the pillow core body. The first blind holes 3 in the same row and in the same direction have the same depth, and the first blind holes 3 in adjacent rows in the same direction have different depths. The blind holes in the same direction are arranged on the same side of the pillow core body, and the blind holes in the other direction are arranged on the same side or the other side of the pillow core body. When all the blind holes are located on the same side, if some blind holes overlap, the depth of the blind hole at the overlap point is the same as the deeper blind hole in the same row. Specific Implementation Example 4
[0033] The pillow core consists of two main parts: an upper pillow core 1 and a lower pillow core 2. The upper pillow core 1 has a downward-facing array of blind holes, and / or the lower pillow core 2 has an upward-facing array of blind holes. Preferably, the extension direction of the blind hole array on the upper pillow core is perpendicular to the extension direction of the blind hole array on the lower pillow core. More preferably, the extension direction of the blind hole array on the upper pillow core is the same as the length direction of the upper pillow core, and the extension direction of the blind hole array on the lower pillow core is the same as the width direction of the lower pillow core. This better meets ergonomic requirements and satisfies the head height requirements for both side-sleeping and back-sleeping positions. The indentation under this structure, for example... Figure 5 As shown, Figure 5 In the diagram, darker colors indicate a larger indentation ratio, while lighter colors indicate a smaller indentation ratio. White areas represent areas where the original material's indentation ratio remains unchanged. Regarding the connection methods between the upper and lower pillow cores: Option 1: The upper pillow core is directly pressed onto the lower pillow core, and both are filled within the same pillowcase, thus positioning them. Option 2: The upper pillow core is glued to the lower pillow core. Option 3: One of the upper or lower pillow cores has a connecting groove, and the other has a protrusion that inserts into the groove. The connection between the upper and lower pillow cores is achieved by inserting the protrusion into the groove. Option 4: The first blind holes 3 of the upper and lower pillow cores are aligned. A connector is filled within the aligned first blind holes 3 to connect the upper and lower pillow cores. The connector is preferably a cylindrical rubber column, with one end inserted into the first blind hole 3 of the upper pillow core and the other end inserted into the first blind hole 3 of the lower pillow core. Option 5: For upper and lower pillow cores containing heat-melting materials, they can be connected by heat fusion.
[0034] The upper and lower pillow cores can be made of the same or different materials. Preferably, the lower pillow core is harder than the upper pillow core, so that the lower pillow core serves as the support layer and the upper pillow core serves as the comfort layer.
[0035] In the above embodiments, a row of at least five second blind holes 4 can be provided along the length of the pillow core body. The second blind holes 4 are located near the edge of the pillow core body. This improves neck comfort by utilizing the second blind holes 4. In embodiment 4, the second blind holes 4 are preferably located on the upper pillow core, with the blind hole array near the top of the upper pillow core and the second blind holes 4 near the bottom of the upper pillow core, as shown in the attached figure.
[0036] In the above embodiments, the first blind hole 3, except for the blind hole for accommodating the connector, is left empty. The second blind hole can be filled to meet the requirement of rigid support. Alternatively, the second blind hole can be left empty to meet the requirement of soft support. A strip-shaped groove can be used instead of the second blind hole to facilitate filling it with cervical pillows, air fresheners, essential oils, etc.
[0037] In the above embodiments, the foaming material can be memory foam, latex, silicone, etc.
[0038] The above-described Examples 1 and 2 can be used alone or in conjunction with a regular pillow core.
