By setting the material density of the pillow pad to be lower than that of the pillow body, the pillow pad can provide comfort and breathability, while the pillow body can provide support and firmness, thus achieving a combination of support and firmness as well as comfort and breathability. This achieves differentiated support in different zones, avoiding the problem of insufficient support caused by using only a single material.

[0004] This utility model provides a pillow, including a pillow body and a pillow pad. The pillow body includes at least one usable surface, and any usable surface has a placement groove. The pillow pad is detachably disposed in the placement groove, and the material density of the pillow pad is lower than that of the pillow body.

[0005] This utility model's technical solution utilizes a modular design for the pillow pad, allowing for independent disassembly and replacement. This extends product lifespan, reduces maintenance costs, and enhances user experience. By setting the pillow pad's material density lower than that of the pillow itself, the pad provides comfortable breathability, while the pillow itself provides supportive firmness. This achieves a balance between supportive firmness and comfortable breathability, enabling differentiated support in different zones and avoiding the insufficient support issues that arise from using only a single material.

[0006] According to the aforementioned embodiments of this utility model, the usable surface includes a first usable surface and a second usable surface disposed along the width direction of the pillow body. The first usable surface is located on one side of the pillow body in the thickness direction and is used to support the head. The second usable surface is located on one side of the pillow body in the length direction and is used to support the neck. A placement groove is recessed relative to the first and second usable surfaces, connecting the first and second usable surfaces. The placement groove extends downwards along the first usable surface to form a curved surface on the second usable surface. The pillow pad is embedded in the placement groove, and the outer shape of the pillow pad matches the inner wall shape of the placement groove. When the pillow pad is placed in the placement groove, the surface of the pillow pad extends and connects with the surface of the pillow body, forming a single pillow surface. This utility model's technical solution, by embedding the pillow pad in the placement groove, ensures that the edge of the pillow pad fits tightly against the inner wall of the placement groove after installation, preventing displacement during use. The pillow pads, located on the first and second usable surfaces respectively, can support the head and neck respectively, improving comfort.

[0007] According to the aforementioned embodiments of this utility model, the distance between the inner walls of the placement groove on the second use surface is greater than the distance between the inner walls of the placement groove on the first use surface. In this utility model's technical solution, by setting the width of the placement groove on the second use surface to be greater than the width of the placement groove on the first use surface, and the width of the pillow on the second use surface to be greater than the width on the first use surface, it is beneficial to adapt to the physiological characteristic that the width of the neck and shoulders is greater than the width of the head contact area, increasing the contact area between the pillow and the neck and shoulders to form a wider support area for the neck and shoulders, thereby adapting to the physiological curve of the cervical spine and the contact area with the back of the neck, and improving user comfort.

[0008] According to the aforementioned embodiments of this utility model, the pillow body further includes a support surface, and the pillow further includes a support pad assembly.

[0022] This utility model provides a pillow with an independently replaceable pillow pad, effectively extending the pillow's lifespan. By setting the material density of the pillow pad to be lower than that of the pillow body, the pillow pad can provide comfort and breathability, while the pillow body can provide support and firmness, thus achieving a combination of support and firmness as well as comfort and breathability. This achieves differentiated support in different zones, avoiding the problem of insufficient support caused by using only a single material.

[0023] like Figures 1 to 7 As shown, this utility model embodiment provides a pillow, including: a pillow body 100 and a pillow pad 200. The pillow body 100 includes at least one usable surface, and any usable surface is provided with a placement groove 140. The placement groove 140 has a depth of about 3-5 cm and is located at the center of the usable surface. The pillow pad 200 is detachably disposed in the placement groove 140, and the material density of the pillow pad 200 is lower than that of the pillow body 100.

[0024] This utility model's technical solution utilizes a modular design for the pillow pad 200, allowing for independent disassembly and replacement. When the pillow pad 200 ages, it can be replaced separately without replacing the entire pillow, thus extending product lifespan, reducing maintenance costs, and improving user experience. By setting the material density of the pillow pad 200 to be lower than that of the pillow body 100, when the user lies flat on the pillow body 100, the user's head rests on the pillow pad 200. The pillow pad 200 provides comfortable breathability, while the pillow body 100 provides supportive firmness, achieving a balance between supportive firmness and comfortable breathability. This provides differentiated support for different zones, avoiding the problem of insufficient support caused by using only a single material.

[0025] Preferably, the pillow body 100 is made of 60D density memory foam, and the pillow pad 200 includes high-resilience polyurethane open-cell cotton. This utility model's technical solution uses different materials for the pillow body 100 and the pillow pad 200. The pillow body 100, including memory foam, can deform according to the user's head shape, providing good support, and also has a memory function, returning to its original shape after use. The pillow pad 200, including high-resilience polyurethane open-cell cotton, improves breathability and resilience, enhancing support and facilitating differentiated support in different areas, avoiding the problem of insufficient support caused by using only a single material.

[0026] Preferably, the inner wall of the placement groove 140 may also be provided with anti-slip textures such as corrugations or mesh to prevent the pillow 200 from falling off the placement groove 140. The pillow 200 may also be installed in the placement groove 140 by using an adhesive substance such as glue to fix the pillow 200 in the placement groove 140.

[0027] like Figures 1 to 3 As shown, the use surface includes a first use surface 110 and a second use surface 120 arranged along the width direction S2 of the pillow body 100. The first use surface 110 is located on one side of the thickness direction S1 of the pillow body 100 and is used to support the head. The second use surface 120 is located on one side of the length direction S3 of the pillow body 100 and is used to support the neck.

[0028] like Figures 1 to 3As shown, the placement groove 140 is recessed relative to the first use surface 110 and the second use surface 120. The placement groove 140 connects the first use surface 110 and the second use surface 120, and extends downward along the first use surface 110 to form a curved surface on the second use surface 120. The pillow 200 is embedded in the placement groove 140, and the external shape of the pillow 200 matches the shape of the inner wall of the placement groove 140. When the pillow 200 is placed in the placement groove 140, the surface of the pillow 200 extends and connects with the surface of the pillow body 100, so that the surface of the pillow 200 and the surface of the pillow body 100 form the same pillow surface, and the edge of the pillow 200 is at least partially attached to the support pad assembly 300. This utility model's technical solution, by embedding the pillow 200 in the placement groove 140, ensures that after installation, the edge of the pillow 200 is tightly attached to the inner wall of the placement groove 140, preventing displacement during use. The pillow 200 is located on the first use surface 110 and the second use surface 120 respectively, which can support the head and neck respectively, improving the comfort of use.

[0029] like Figures 1 to 2 As shown, the distance between the placement groove 140 on the second use surface 120 and its inner walls on both sides is greater than the distance between the placement groove 140 on the first use surface 110 and its inner walls on both sides. In this invention, by setting the width of the placement groove 140 on the second use surface 120 to be greater than the width of the placement groove 140 on the first use surface 110, and the width of the pillow 200 on the second use surface 120 to be greater than the width on the first use surface 110, it is beneficial to adapt to the physiological characteristic that the width of the neck and shoulders is greater than the width of the head, increasing the contact area between the pillow 200 and the neck and shoulders, thus forming a wider support area for the neck and shoulders, thereby adapting to the physiological curve of the cervical spine and the contact area with the back of the neck, and improving user comfort.

[0030] like Figures 1 to 3 As shown, the pillow body 100 also includes a support surface 130, and the pillow also includes a support pad assembly 300.

[0031] like Figures 2 to 3As shown, the support pad assembly 300 is detachably disposed on the support surface 130, and the projection of the pillow pad 200 in the thickness direction of the pillow body 100 has at least a partial overlap area with the support pad assembly 300. The support pad assembly 300 includes at least one pad 310 arranged sequentially along the thickness direction S1 of the pillow body 100. Adjacent pads 310 are detachably connected, and adjacent pads 310 have at least a partial overlap area in the thickness direction of the pillow body 100. Specifically, the pads 310 and the pillow body 100, and adjacent pads 310, can be detachably connected by Velcro, snap fasteners, or magnetic adsorption. Adjacent pads 310 can also be simply stacked to make them detachably connected. This utility model's technical solution involves setting a support pad assembly 300 on the usable surface of the pillow body 100. The support pad assembly 300 includes at least one pad 310 arranged sequentially along the thickness direction S1 of the pillow body 100. This allows users to easily add or remove the number of support pads 310 as needed. When the pillow height needs to be increased, the number of pads 310 can be increased; when the pillow height needs to be decreased, the number of pads 310 can be decreased, thereby meeting the personalized needs of different users. Different materials and thicknesses of pads 310 can also be replaced, thus achieving adjustable pillow height and support stiffness, which is beneficial for adapting to different users' sleeping posture needs and improving comfort. The partial overlap between the pillow pad 200 and the support pad assembly 300, as well as the overlapping arrangement between the pads 310, provides stable support in the horizontal direction, preventing the pillow pad 200 and pads 310 from shifting during use. Through the modular design of the support pad assembly 300, all pads 310 can be independently disassembled and replaced, which helps extend the product's service life, reduce maintenance costs, and improve the user experience.

[0032] Preferably, the support pad assembly 300 includes an elastic sponge, such as a high-density foam or a polyurethane elastic sponge, which has good elasticity and support. In addition to elastic sponge, the pad 310 may also be made of honeycomb polymer, gel pad, or latex material to obtain different support and heat dissipation characteristics.

[0033] like Figures 1 to 2 As shown, at least a portion of the inner wall of the placement groove 140 has an arc-shaped structure. This utility model's technical solution, by making at least a portion of the inner wall of the placement groove 140 arc-shaped and at least a portion of the pillow 200 also arc-shaped (e.g., the headrest area 111 is arc-shaped), can adapt to the shape of the head; or by setting an arc-shaped structure in the neck pillow area 121, it can adapt to the curve of the neck and shoulders, improving the support of the pillow 200 and enhancing user comfort. Furthermore, the arc-shaped structure of at least a portion of the inner wall of the placement groove 140 helps reduce friction between the pillow 200 and the inner wall of the placement groove 140, improving fit.

[0034] like Figures 1 to 2As shown, the first usable surface 110 includes a headrest area 111 and side-lying areas 112 located on opposite sides of the headrest area 111. A placement slot 140 is located in the headrest area 111, as... Figures 5 to 6 As shown, the top surface of the headrest area 111 after the pillow 200 is placed is lower than the top surface of the side-lying area 112 to accommodate the height difference between the head and shoulder when lying on the side. Preferably, the surface of the headrest area 111 is a slightly concave curved surface, which can better conform to the curve of the user's head, reduce pressure points, and provide more comfortable support.

[0035] like Figures 1 to 2 As shown, two side-lying areas 112 are arranged opposite each other along the length direction S3 of the pillow body 100. Each side-lying area 112 is provided with an ear placement part 113, which includes multiple recessed cavities 1131 arranged in an array. For example, the recessed cavities 1131 can be arranged in a rectangular array, a cross array, an S-shaped array, etc., and there are 3-5 recessed cavities 1131. The recessed cavities 1131 are recessed towards the thickness direction S1 of the pillow body 100, with a recess depth of 1.5-2.5cm. By providing the ear placement part 113, which includes multiple recessed cavities 1131 arranged in an array and recessed towards the thickness direction S1 of the pillow body 100, this invention allows the ear to be placed in the recessed cavity 1131 when the user is lying on their side. This effectively disperses pressure on the auricle and face, reduces pressure on the auricle, and improves side-lying comfort.

[0036] When a user lies on their side on the pillow body 100, if the user's head is resting on the pillow pad, the pillow pad provides comfortable breathability and relieves ear pressure because its material density is lower than that of the pillow body. Meanwhile, the pillow body provides supportive firmness. If the user's head is resting on the side-lying area, the ear will be relatively resting on the ear placement area. Because the ear placement area has multiple recessed cavities 1131, the ear is not completely sealed by the pillow body 100. The recessed cavities 1131 can release ear pressure, thus effectively relieving ear pressure.

[0037] Furthermore, the recessed cavities 1131 can also be evenly distributed along the length direction S3 of the pillow body 100 within the side-lying area 112, with the depth of the recessed cavities 1131 gradually increasing from the outer side to the inner side of the side-lying area 112. For example, the depth of the outermost recessed cavity 1131 is 1.8cm, and the depth of the innermost recessed cavity 1131 is 2.2cm, so as to suit users with different ear sizes and longer side-sleeping time. The gradually changing depth of the recessed cavities 1131 helps to further reduce ear pressure and avoid ear numbness caused by prolonged side-sleeping.

[0038] Furthermore, a soft silicone pad is detachably attached inside the recessed cavity 1131, and the inner wall of the recessed cavity 1131 has an arc-shaped surface that matches the curvature of the outer side of the auricle to fit the user's ear shape and reduce local pressure.

[0039] like Figures 1 to 2 As shown, the second usable surface 120 includes a neck pillow area 121, which includes an arc-shaped structure. This arc-shaped structure protrudes towards the side away from the pillow body 100. Preferably, the arc-shaped structure is an ergonomic curved surface that conforms to the user's cervical spine curve, providing good support for the cervical spine, effectively relieving cervical pressure, and helping to prevent cervical spine problems. The pillow pad 200 has a curved surface structure that conforms to the arc-shaped structure. A placement slot 140 is located in the neck pillow area 121. The neck pillow area 121 and the head pillow area 111 are integrally formed, and a smooth transition structure is provided between them. For example, a smooth arc surface is provided to avoid abruptness at the junction of the head and neck. This utility model's technical solution, by providing an arc-shaped structure in the neck pillow area 121 and separating the head pillow area 111 and neck pillow area 121 through a smooth transition structure, facilitates providing ergonomic support for the head and neck when the user is lying supine or on their side.

[0040] Preferably, such as Figure 2 As shown, an inwardly recessed surface 150 is formed on the outer side of each of the two ends of the pillow body 100. The inwardly recessed surface 150 extends obliquely backward from the front end of the pillow body 100. This utility model's technical solution, by providing inwardly recessed surfaces 150 on the pillow body 100, allows the user's neck to rest against the pillow body 100 when lying on their back or side. The shoulders are within the inward range of the inwardly recessed surface 150. This prevents the user's neck from being unsupported due to obstruction by the pillow body 100, thus achieving a complete support for the neck and shoulders and improving comfort.

[0041] In this application, the support pad assembly 300 includes 2-4 pads 310. In the thickness direction of the pillow body 100, the overlapping area between adjacent pads 310 is not less than 70% of the area of ​​a single pad 310, ensuring overall stability after stacking. Each pad 310 has a thickness of 0.8-1.2 cm, and the length and width of each pad 310 are consistent with the length and width of the pillow body 100, which helps improve support stability.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
