[0028] A pillow is a sleep aid. A suitable pillow conforms to the shape of the head, maintains the normal physiological curvature of the neck, relaxes the neck muscles, and ensures that the user enters a comfortable sleep state.

[0029] Different users have different preferences for pillow firmness. In related technologies, pillow firmness is limited to a single type and cannot be adjusted.

[0030] Please refer to Figures 1 to 2 , Figure 1 This is a structural schematic diagram of a pillow provided in an embodiment of this application. Figure 2 This is an exploded structural diagram of a pillow provided in an embodiment of this application.

[0031] This application provides a pillow 100 to solve the technical problem in the related art that the firmness of the pillow 100 cannot be adjusted.

[0032] The pillow 100 includes a pillow core body 10, a first adjusting core 20, and a second adjusting core 30. The pillow core body 10 has a first receiving hole 11 and a second receiving hole 12 at both ends, respectively. The first receiving hole 11 and the second receiving hole 12 are arranged along a first direction D1 (the length direction of the pillow 100). The pillow core body 10 also has a first mounting cutout 13 and a second mounting cutout 14 at both ends, respectively. The first mounting cutout 13 connects to the first receiving hole 11, and the second mounting cutout 14 connects to the second receiving hole 12. The first adjusting core 20 is disposed within the first receiving hole 11. The second adjusting core 30 is disposed within the second receiving hole 12.

[0033] Specifically, the pillow core body 10 has a first receiving hole 11 and a second receiving hole 12 at both ends, and is connected to the first receiving hole 11 and the second receiving hole 12 through the first mounting cut 13 and the second mounting cut 14 respectively; the first adjusting core 20 and the second adjusting core 30 can be installed into the first receiving hole 11 and the second receiving hole 12 respectively.

[0034] The hardness of the first adjusting core 20 and the second adjusting core 30 can be flexibly selected (for example, using elastic materials with different hardness or filling with structures of different densities). Users can change the hardness of the corresponding area of ​​the pillow 100 (the pillow end where the first receiving hole 11 and the second receiving hole 12 are located) by replacing or adjusting the first adjusting core 20 and the second adjusting core 30 according to their needs, thereby realizing the hardness adjustment of the entire pillow 100, overcoming the defects of fixed pillow hardness in related technologies that cannot adapt to different needs.

[0035] Furthermore, in this embodiment, the pillow core body 10 is an integral structure, and the first adjusting core 20 and the second adjusting core 30 can be installed simply through the first mounting cutout 13 and the second mounting cutout 14 on the side. After installation, the first adjusting core 20 and the second adjusting core 30 can be fixed and the first receiving hole 11 and the second receiving hole 12 can be closed by simply bonding and sealing the first mounting cutout 13 and the second mounting cutout 14. The entire manufacturing process of the pillow 100 has few steps and is simple to operate (no high-precision split assembly process is required), which facilitates the large-scale mass production of the pillow 100.

[0036] Optionally, the material of the pillow core body 10 may include, but is not limited to, memory foam, latex, etc.

[0037] In the pillow 100 provided in this application, the two ends of the pillow core body 10 include a first receiving hole 11 and a second receiving hole 12, both of which are arranged along a first direction D1. The two ends of the pillow core body 10 are also respectively provided with a first mounting cutout 13 and a second mounting cutout 14. The first mounting cutout 13 connects to the first receiving hole 11, and the second mounting cutout 14 connects to the second receiving hole 12. The first adjusting core 20 is disposed within the first receiving hole 11, and the second adjusting core 30 is disposed within the second receiving hole 12. The hardness of the first adjusting core 20 and the second adjusting core 30 can be flexibly selected, thereby realizing the hardness adjustment of the entire pillow 100. Furthermore, the first adjusting core 20 and the second adjusting core 30 can be installed on the pillow 100 through the first mounting cutout 13 and the second mounting cutout 14 on the side. The entire manufacturing process of the pillow 100 has few steps and is simple to operate, facilitating large-scale mass production of the pillow 100.

[0038] In one embodiment, the material hardness of the first adjusting core 20 and the material hardness of the second adjusting core 30 are greater than the material hardness of the pillow core body 10. The material hardness of the first adjusting core 20 and the material hardness of the second adjusting core 30 may be the same or different. In other words, the material hardness of the first adjusting core 20 may be greater than, less than, or equal to the material hardness of the second adjusting core 30.

[0039] The first adjusting core 20 and the second adjusting core 30 have a higher hardness than the pillow core body 10. The purpose is to make the first adjusting core 20 and the second adjusting core 30 the main support, while the pillow core body 10 becomes a comfort auxiliary, avoiding the limitations of a single material and providing different hardness head support for different people.

[0040] The pillow core body 10 is positioned as a basic frame with a wrapping feel. If the pillow core body 10 is too firm, it will lose the soft and conforming feel of the pillow 100, and the user will easily feel uncomfortable when in contact with it; if the pillow core body 10 is too soft, it cannot support the head and neck on its own.

[0041] The positioning of the first adjustment core 20 and the second adjustment core 30 is for precise support supplementation. By setting a material that is harder than the pillow core body 10, after being embedded in the first receiving hole 11 and the second receiving hole 12 of the pillow core body 10, it can provide rigid support in key parts (such as the neck and under the head). It will not lose support due to the pillow core body 10 being too soft, and the support strength can be controlled by the hardness of the first adjustment core 20 and the second adjustment core 30, thus achieving a balance between soft wrapping and hard support.

[0042] With the first adjusting core 20 and the second adjusting core 30 having a harder hardness than the pillow core body 10, and the first adjusting core 20 and the second adjusting core 30 having different hardnesses, they provide two different levels of support, enhancing the user's comfort when using the pillow 100.

[0043] In one embodiment, the first adjusting core 20 is harder than the second adjusting core 30. The first adjusting core 20 is harder and provides stronger support, supporting the weight of the neck and preventing neck collapse when the head is pressed down, making it especially suitable for people whose cervical spine needs support (such as office workers and those who frequently look down at their phones). The second adjusting core 30 is softer and provides gentler support, conforming slightly to the contours of the head, reducing pressure on the scalp and skull (e.g., preventing pressure on the temples when sleeping on one's side), and, combined with the soft wrapping of the pillow core body 10, enhancing relaxation during sleep.

[0044] In one embodiment, the hardness of the first adjusting core 20 may be less than or equal to the hardness of the second adjusting core 30, and this application does not impose any restrictions on this.

[0045] Please refer to Figures 1 to 3 , Figure 3 This is a schematic diagram of another structure of a first adjusting core provided in the embodiments of this application.

[0046] In one embodiment, the cross-sectional shape of the first adjusting core 20 includes one of a circle, a quadrilateral, an ellipse, a triangle, and a regular hexagon, and the cross-sectional shape of the second adjusting core 30 includes one of a circle, a quadrilateral, an ellipse, a triangle, and a regular hexagon.

[0047] It should be noted that, in this embodiment, the first adjusting core 20 and the second adjusting core 30 have the same shape.

[0048] Alternatively, in other embodiments, the first adjustment core 20 and the second adjustment core 30 can be selected to have different shapes. By combining different shapes, the neck and head can obtain targeted body sensation, solving the problem that traditional pillows only have one shape to fit all parts.

[0049] For example, the first adjustment core 20 (corresponding to the neck) is quadrilateral in shape, and the second adjustment core 30 (corresponding to the head) is circular in shape. The quadrilateral first adjustment core 20 provides precise and stable support, maintains the physiological curvature of the cervical spine, prevents head collapse, and solves the problem of insufficient support. The circular second adjustment core 30 provides soft and distributed wrapping, reduces pressure on the scalp and skull, and solves the problem of insufficient comfort. This allows the pillow 100 to achieve an overall feeling of neck stability and head comfort, suitable for the sleep needs of most users, especially office workers and users with initial neck discomfort.

[0050] For example, the first adjustment core 20 (corresponding to the neck) is triangular in shape, and the second adjustment core 30 (corresponding to the head) is elliptical in shape. The triangular first adjustment core 20 can strengthen the support of the cervical spine depression, preventing the neck from being unsupported for users whose cervical curvature has straightened and who need local correction. The elliptical second adjustment core 30 can distribute pressure, counteract the tightness caused by concentrated neck support, and keep the head relaxed.

[0051] It should be noted that this application is only illustrated by the example of the first adjustment core 20 corresponding to the neck and the second adjustment core 30 corresponding to the head. In other embodiments, the first adjustment core 20 and the second adjustment core 30 may also correspond to other body parts of the user, and should not be construed as a limitation of this application.

[0052] Please refer to Figures 1 to 4 , Figure 4 This is a schematic diagram of the side structure of a pillow provided in an embodiment of this application. Figure 1 .

[0053] In one embodiment, the first mounting notch 13 and the second mounting notch 14 are parallel to a preset plane (a horizontally placed plane).

[0054] It should be noted that the preset plane is the support plane when the pillow 100 is placed horizontally (i.e., the normal placement surface).

[0055] When the first mounting cut 13 and the second mounting cut 14 are parallel to the preset plane, the edges of the pillow core body 10 can maintain a more natural and smooth curved transition. When the user's head and neck come into contact with the pillow 100, there will be no "gap" or "foreign object" sensation due to improper orientation of the first mounting cut 13 and the second mounting cut 14, resulting in a better fit and thus improving the overall comfort of the user when lying down using the pillow 100.

[0056] In one embodiment, the pillow 100 further includes a first adhesive member and a second adhesive member, the first adhesive member being disposed within the first mounting cut 13 and the second adhesive member being disposed within the second mounting cut 14.

[0057] It should be noted that the first adjusting core 20 and the second adjusting core 30 are inserted into the receiving hole and the second receiving hole 12 of the pillow core body 10 through the first mounting cut 13 and the second mounting cut 14. If the first mounting cut 13 and the second mounting cut 14 are not sealed, the adjusting core and the second adjusting core 30 may slide or even fall out in the first receiving hole 11 and the second receiving hole 12 during daily use, and completely lose their supporting function.

[0058] The first adhesive is embedded in the first mounting cutout 13 and the second adhesive is embedded in the second mounting cutout 14, which can seal the first mounting cutout 13 and the second mounting cutout 14 by adhesive bonding. The first adjusting core 20 and the second adjusting core 30 are respectively restricted in the first receiving hole 11 and the second receiving hole 12, and cannot slide or fall out.

[0059] The first adhesive and the second adhesive are embedded in the first mounting cut 13 and the second mounting cut 14, rather than protruding from the surface of the pillow core body 10. After pasting, the surfaces of the first mounting cut 13 and the second mounting cut 14 remain flat and will not form protruding foreign objects like zipper heads or snaps, thus avoiding pressure when the head and neck come into contact with them and improving the user experience of the pillow 100.

[0060] Optionally, in one embodiment, the first and second adhesive members can also be Velcro, which has the characteristic of being repeatedly openable and closable, rather than being a one-time adhesive. When it is necessary to clean the pillow core body 10 or replace the first adjusting core 20 and the second adjusting core 30, simply peel off the first or second adhesive member to reopen the first mounting cut 13 or the second mounting cut 14, remove the first adjusting core 20 or the second adjusting core 30 for replacement, and after the operation is completed, reattach the first or second adhesive member to restore the cut to a closed state, without affecting subsequent use.

[0061] Please refer to Figures 1 to 5 , Figure 5 This is a schematic diagram of the side structure of a pillow provided in an embodiment of this application. Figure 2 .

[0062] In one embodiment, the pillow core body 10 includes a first pillow core edge 15, a connecting portion 16, and a second pillow core edge 17 connected together. The first receiving hole 11 is provided on the first pillow core edge 15, and the second receiving hole 12 is provided on the second pillow core edge 17.

[0063] Furthermore, the thickness of the first pillow core edge 15 along the second direction D2 is H1, and the thickness of the second pillow core edge 17 along the second direction D2 is H2. H1 and H2 satisfy: H1≥H2, wherein the second direction D2 is perpendicular to the preset plane.

[0064] It should be noted that H1 and H2 satisfy the condition that H1 ≥ H2, including the thickness H1 of the first pillow core edge 15 being greater than the thickness H2 of the second pillow core edge 17, or the thickness H1 of the first pillow core edge 15 being equal to the thickness H2 of the second pillow core edge 17. The above are all embodiments of this application and should not be construed as limitations on this application.

[0065] Furthermore, when the thickness H1 of the first pillow core edge 15 is equal to the thickness H2 of the second pillow core edge 17, the thicknesses of the first pillow core edge 15 and the second pillow core edge 17 of the pillow core body 10 are consistent in the height direction (the second direction D2). In this case, the molding process of the pillow core body (such as mold design and one-piece molding process) is more uniform, eliminating the need to design different thickness structures for both ends, simplifying the manufacturing difficulty of the pillow core body, and facilitating the mass production of the pillow 100.

[0066] When the thickness H1 of the first pillow core edge 15 is equal to the thickness H2 of the second pillow core edge 17, the function of adjusting the feel can be achieved through the differences in size and material between the first adjusting core 20 and the second adjusting core 30. For example, adjusting the filling height and volume of the first adjusting core 20 in the first receiving hole 11, and adjusting the filling height and volume of the second adjusting core 30 in the second receiving hole 12; or, for example, using materials of different hardness and elasticity for the first adjusting core 20 and the second adjusting core 30 to directly adjust the contact feel. This allows the pillow 100 of this application to achieve both universality of the pillow core body and flexible adjustment of the feel during use.

[0067] When the thickness H1 of the first pillow core edge 15 is greater than the thickness H2 of the second pillow core edge 17, the first pillow core edge 15 has a greater thickness in the height direction, and the second pillow core edge 17 has a smaller thickness. The pillow core body naturally forms a structure with more sufficient basic support at one end (the side of the first pillow core edge 15) and slightly weaker basic support at the other end (the side of the second pillow core edge 17).

[0068] It should be noted that the neck typically requires stronger support (corresponding to the first pillow core edge 15, the support can be enhanced by the first adjusting core 20, such as using a high-hardness material or fuller filling to utilize a larger thickness space); the back of the head may be more suitable for slightly softer, more conforming support (corresponding to the second pillow core edge 17, the second adjusting core 30 can be adapted to a low-hardness, easily conforming configuration). This combination of the thickness difference of the pillow core body and the material performance difference of the first adjusting core 20 and the second adjusting core 30 can more accurately adapt to the physiological structural differences of the human head and neck, further improving the fit and comfort of the pillow 100; at the same time, the personalized needs of different users can still be accommodated by changing the material types of the first adjusting core 20 and the second adjusting core 30.

[0069] In one embodiment, the first receiving hole 11 passes through the first pillow core edge 15 along the first direction D1, and the second receiving hole 12 passes through the second pillow core edge 17 along the first direction D1, so that the user can take out the first adjusting core 20 and the second adjusting core 30 for cleaning and replacement.

[0070] Please refer to Figures 1 to 5 In one embodiment, the radial dimension of the first adjusting core 20 is greater than the radial dimension of the second adjusting core 30.

[0071] The radial dimensions of the first adjusting core 20 and the second adjusting core 30 can be understood as the thickness or cross-sectional area of ​​the first adjusting core 20 and the second adjusting core 30.

[0072] The first adjustment core 20 has a larger radial dimension, making it less prone to deformation under stress and providing stronger support (similar to a harder filler block, providing more stable support). The second adjustment core 30 has a smaller radial dimension, making it easier to adapt and deform under stress, providing relatively softer support (similar to a softer filler block, providing a better fit).

[0073] Furthermore, by making the first adjusting core 20 (corresponding to the neck area) have a large radial dimension and strong support, and the second adjusting core 30 (corresponding to the head area) have a small radial dimension and gentle support, the pillow 100 can provide two different levels of support, improving the user's comfort when using the pillow 100. Moreover, the pillow 100 can precisely match the different needs of the user's head and neck, conforming to ergonomic design, thereby effectively improving the overall comfort of the pillow 100.

[0074] Please refer to Figures 1 to 5 Furthermore, the radial dimension of the first adjusting core 20 is A1, the radial dimension of the second adjusting core 30 is A2, the ratio of A1 to A2 is α, and α satisfies: 1≤α≤2.

[0075] The ratio of A1 to A2 is α, where α satisfies: 1 ≤ α ≤ 2. Specifically, the minimum boundary of α is α = 1, A1 = A2, and the radial dimensions of the first adjusting core 20 and the second adjusting core 30 are completely identical. The maximum boundary of α is α = 2, A1 = 2A2, and the radial dimension of the first adjusting core 20 is twice that of the second adjusting core 30. The intermediate range of α is 1 < α < 2, where A1 is slightly larger than A2, and the difference is controlled within the range of 1 to 2 times.

[0076] Furthermore, when α=1 (A1=A2), the first adjustment core 20 and the second adjustment core 30 are exactly the same size. After being inserted into the corresponding first receiving hole 11 and second receiving hole 12, the basic filling fullness is the same, but the different support feel can still be achieved through the material difference between the first adjustment core 20 and the second adjustment core 30.

[0077] For example, the first adjustment core 20 is made of a high-hardness material, while the second adjustment core 30 is made of a low-hardness material. Even if the first adjustment core 20 and the second adjustment core 30 are the same size, the difference in material hardness between the first adjustment core 20 and the second adjustment core 30 will provide stable support on the side of the first adjustment core 20 (corresponding to the neck) and provide a soft fit on the side of the second adjustment core 30 (corresponding to the head). This retains the manufacturing convenience brought by the uniform size, while also compensating for the difference in feel through the materials, avoiding the complexity caused by the structural differences between the first receiving hole 11 and the second receiving hole 12 due to different sizes.

[0078] Furthermore, when 1 < α ≤ 2 and A1 > A2, the radial dimension A1 of the first adjustment core 20 is larger, providing stronger support and meeting the neck's need for stable support. The radial dimension A2 of the second adjustment core 30 is smaller, providing gentler support and meeting the head's need for a close and relaxed fit, reducing pressure on the head.

[0079] Furthermore, the α condition satisfies: 1 ≤ α ≤ 2. If α > 2, the first adjustment core 20 will have excessively strong support (too high hardness), causing a feeling of pressure when the neck contacts it; or, the second adjustment core 30 will have insufficient support, causing the head to sink in easily, resulting in an imbalance of force on the head and neck. The condition that α satisfies: 1 ≤ α ≤ 2 allows the difference in support force to be kept within a moderate and effective range, allowing the user to clearly perceive the difference between more stable neck support and softer head support, without causing discomfort due to extreme differences, thus achieving a balance between differentiation and comfort.

[0080] In one embodiment, the thickness of the first pillow core edge 15 along the second direction D2 is H1, and the ratio of H1 to A1 is β, wherein β satisfies: 2≤β≤4.

[0081] The β satisfies: 2≤β≤4, in other words, the thickness of the first pillow core edge 15 is 2-4 times the radial dimension of the first adjustment core 20.

[0082] The β condition satisfies 2 ≤ β ≤ 4, ensuring that the pillow 100 provides sufficient deformation space for a soft and conforming fit. When the user's head or neck comes into contact with the pillow 100, the first pressure is applied to the outer first pillow core edge 15. Since the thickness of the first pillow core edge 15 is much greater than the radial dimension of the first adjustment core 20, it has more room to deform appropriately. For example, when the head presses down, the first pillow core edge 15 will concave along the curve of the head, wrapping around both sides of the head; when the neck is in contact, the first pillow core edge 15 will conform to the natural forward curve of the cervical spine, avoiding a hard, angular feel.

[0083] If the proportion is too small, the first pillow core edge 15 will be too thin, resulting in insufficient cushioning space. When the head presses down, it will directly touch the firmer first adjustment core 20 inside, significantly reducing the softness and even causing a feeling of pressure. If the proportion is too large, the first pillow core edge 15 will be too thick, leading to excessive cushioning and insufficient support.

[0084] Therefore, β satisfies: 2≤β≤4, and the deformation of the first pillow core edge 15 is moderately controllable: when the user's head or neck presses down only a short distance, it can contact the first adjusting core 20, and the support force is transmitted in time, neither leaving the cervical spine unsupported nor excessively lifted. Optionally, β can be 2, or 2.2, or 2.5, or 2.7, or 2.9, or 3, or 3.1, or 3.5, or 4, or other values ​​within the range of 2-4.

[0085] The thickness of the second pillow core edge 17 along the second direction D2 is H2, and the ratio of H2 to A2 is γ, wherein γ satisfies: 2≤γ≤4.

[0086] The γ satisfies: 2≤γ≤4, in other words, the thickness of the second pillow core edge 17 is 2-4 times the radial dimension of the second adjustment core 30.

[0087] The γ satisfies 2≤γ≤4, so that the pillow 100 can provide sufficient deformation space to achieve a soft and conforming fit. When the user's head or neck comes into contact with the pillow 100, the outer second pillow core edge 17 is pressed first. Since the thickness of the second pillow core edge 17 is much larger than the radial dimension of the second adjustment core 30, it has more room to undergo moderate deformation. For example, when the head is pressed down, the second pillow core edge 17 will be concave along the curve of the head shape and wrap around the sides of the head; when the neck is in contact, the second pillow core edge 17 will conform to the natural forward curve of the cervical spine, avoiding a hard, angular feeling.

[0088] If the proportion is too small, the second pillow core edge 17 will be too thin, resulting in insufficient cushioning space. When the head presses down, it will directly touch the firmer second adjustment core 30 inside, significantly reducing the softness and even causing a feeling of pressure. If the proportion is too large, the second pillow core edge 17 will be too thick, leading to excessive cushioning and insufficient support.

[0089] Therefore, γ satisfies: 2≤γ≤4, and the deformation of the second pillow core edge 17 is moderately controllable: when the user's head or neck presses down only a short distance, it can contact the second adjusting core 30, and the support force is transmitted in time, neither leaving the cervical spine unsupported nor excessively lifted. Optionally, γ can be 2, or 2.2, or 2.5, or 2.7, or 2.9, or 3, or 3.1, or 3.5, or 4, or other values ​​within the range of 2-4.

[0090] Please refer to Figures 1 to 5 In one embodiment, the pillow core body 10 includes a first pillow surface 18 and a second pillow surface 19 facing away from each other. The first pillow surface 18 includes a first arc-shaped surface 181, a second arc-shaped surface 182, and a third arc-shaped surface 183. The second arc-shaped surface 182 is a concave surface. The first arc-shaped surface 181 and the third arc-shaped surface 183 protrude from the second arc-shaped surface 182.

[0091] The first arc-shaped surface 181 and the third arc-shaped surface 183 protrude from the second arc-shaped surface 182, which can adapt to the curve of the human neck. The second arc-shaped surface 182 is a concave surface, which can adapt to the curve of the human head, so that the shape of the first pillow surface 18 conforms to ergonomics and improves the comfort of using the pillow 100.

[0092] The second pillow surface 19 includes a fourth arc-shaped surface 191, a fifth arc-shaped surface 192, and a sixth arc-shaped surface 193. The fifth arc-shaped surface 192 is a concave surface, and the fourth arc-shaped surface 191 and the sixth arc-shaped surface 193 protrude relative to the fifth arc-shaped surface 192.

[0093] Similarly, the fourth arc-shaped surface 191 and the sixth arc-shaped surface 193 protrude from the fifth arc-shaped surface 192, which can adapt to the curve of the human neck. The fifth arc-shaped surface 192 is a concave surface, which can adapt to the curve of the human head, so that the shape of the second pillow surface 19 conforms to ergonomics and improves the comfort of using the pillow 100.

[0094] The first pillow surface 18 and the second pillow surface 19 have a symmetrical structure facing away from each other. The pillow 100 does not need to distinguish between the front and back sides and can be used with either side facing up. The pillow 100 of this application can adapt to different sleeping positions and different people's preferences, while extending its service life.

[0095] Please refer to Figures 1 to 5 In one embodiment, the second arcuate surface 182 is provided with a plurality of grooves 40, which extend along the first direction D1.

[0096] The second arc-shaped surface 182 is provided with a plurality of grooves 40, which can reduce the hardness of the pillow core body corresponding to the part of the second arc-shaped surface 182, making the support softer and more in line with the contour of the head and neck, thereby improving the comfort of the pillow 100.

[0097] Furthermore, the groove 40 has a hollow structure, extending along the first direction D1 to form multiple parallel ventilation channels. Air can flow from one end of the pillow 100 to the other along the channels, breaking the sealed contact between the head and neck and the pillow surface, reducing heat and moisture accumulation, improving air circulation efficiency, relieving stuffiness in the neck support area, and making the pillow 100 more versatile.

[0098] In one embodiment, the groove 40 extends through the pillow core body along the first direction D1.

[0099] The groove 40 penetrates the pillow core body along the first direction D1; in other words, the groove 40 forms a continuous channel extending from one end of the pillow core body to the other end.

[0100] When cleaning the pillow 100, cleaning tools (such as wet wipes or small brushes) can be inserted directly into the groove 40 from one end to the other, ensuring full contact with all surfaces inside the groove 40. This avoids the problem of dirt accumulating at the closed end and creating cleaning dead zones, which is common in non-penetrating grooves (closed at one end). After cleaning, air can circulate quickly along the through groove 40, and moisture can evaporate from both ends, reducing residual moisture, lowering the risk of mold growth, and making it easier to maintain the hygiene and dryness inside the groove 40. Furthermore, during use, any dandruff, sweat residue, dust, or other impurities that may accumulate in the groove 40 can be cleaned out from one end along the through-channel (or fall off naturally), eliminating the need for repeated rubbing and cleaning of specific areas. This makes the process more efficient. The through-channel design of the groove 40 also makes cleaning simpler and more thorough, helping to maintain the hygiene and user experience of the pillow 100 over the long term.

[0101] It should be noted that, in this embodiment, the orthographic projection of the groove 40 onto the preset plane is offset from the orthographic projections of the first adjusting core 20 and the second adjusting core 30 onto the preset plane.

[0102] Please refer to Figures 1 to 6 , Figure 6 This is an enlarged structural diagram of the groove portion of a pillow provided in an embodiment of this application.

[0103] In one embodiment, the depth of the groove 40 ranges from 1 cm to 3 cm.

[0104] Optionally, the depth of the groove 40 can be 1cm, 1.1cm, 1.3cm, 1.5cm, 1.7cm, 1.9cm, 2.2cm, 2.4cm, 2.5cm, 2.8cm, 3cm, or other values ​​within the range of 1cm-3cm. This application does not impose any restrictions on this.

[0105] In one embodiment, the groove 40 includes a first groove portion 41 and a second groove portion 42. The groove spacing of the first groove portion 41 is L1, and the groove spacing of the second groove portion 42 is L2. The ratio of L1 to L2 is θ, and θ satisfies: 1≤θ≤3.

[0106] The first groove portion 41 has a large spacing, forming a fine micro-ventilation channel, which can accurately guide local moisture (such as sweat) in the head contact area and avoid small-scale stuffiness accumulation.

[0107] The spacing between the second groove portions 42 is smaller, and the pillow surface protrusion around the second groove portion 42 is wider, resulting in stronger structural rigidity, less deformation under pressure, and the ability to provide stable support.

[0108] In short, the same groove 40, by setting the first groove portion 41 and the second groove portion 42, simultaneously achieves the adaptation of support force and breathability, making the pillow 100 both comfortable and cool without being stuffy.
