Description

Technical Field

[0001] This utility model relates to the field of pillow technology, specifically a zero-pressure pillow with built-in neck support. Background Technology

[0002] As people place increasing importance on healthy sleep, zero-pressure pillows, as bedding that can effectively relieve neck pressure and improve sleep quality, are gradually gaining widespread attention. Through their unique design and materials, zero-pressure pillows conform to the curve of the human neck, providing even support and reducing discomfort caused by excessive localized pressure during sleep, thus helping users achieve a more comfortable sleep experience.

[0003] Existing zero-pressure pillows typically use support rods inside the pillow core to achieve different levels of firmness. The side closer to the support rod is firmer, while the side farther away is relatively softer, thus providing different levels of support. However, since the support rods are often fixed inside the pillow core, users cannot flexibly adjust or remove them according to their actual needs, which seriously affects the user experience.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] Regarding the aforementioned problem that existing support rods are often fixed inside the pillow core, preventing users from flexibly adjusting or removing them according to actual needs and severely impacting the user experience, the technical solution adopted by this utility model to solve this problem is:

[0006] A zero-pressure pillow with built-in neck support includes a pillow body, the pillow body including a neck support area for supporting the neck, a headrest area for supporting the head and connected to the neck support area, a receiving cavity located inside the pillow body, and a support body, the receiving cavity being provided with an elastic filling component, and the support body being detachably disposed below the receiving cavity on the side near the neck support area.

[0007] Furthermore, the pillow body is provided with an installation channel extending along the neck support direction, the installation channel penetrating the pillow body, and the support body extending into the installation channel to restrict the installation position of the support body on the pillow body.

[0008] Furthermore, the accommodating cavity includes a first accommodating cavity located below the neck brace area and a second accommodating cavity located below the headrest area, the first accommodating cavity and the second accommodating cavity being independently configured.

[0009] Furthermore, the first accommodating cavity includes a first upper accommodating cavity located near the neck brace area, a first bottom accommodating cavity located near the support body, and a first middle accommodating cavity located between the first upper accommodating cavity and the first bottom accommodating cavity. The elastic filling component includes a first elastic filling material disposed in the first upper accommodating cavity, a second elastic filling material disposed in the first middle accommodating cavity, and a third elastic filling material disposed in the first bottom accommodating cavity. The first upper accommodating cavity, the first middle accommodating cavity, and the first bottom accommodating cavity are independently disposed and form a three-layer structure.

[0010] Furthermore, the first elastic filler material is polyurethane foam, the second elastic filler material is memory foam, and the third elastic filler material is latex particle filler.

[0011] Furthermore, the second accommodating cavity includes a second upper accommodating cavity located near the headrest area, a second bottom accommodating cavity adjacent to the first bottom accommodating cavity, and a second middle accommodating cavity located between the second upper accommodating cavity and the second bottom accommodating cavity. The elastic filling component includes a fourth elastic filling material disposed in the second upper accommodating cavity, a fifth elastic filling material disposed in the second middle accommodating cavity, and a sixth elastic filling material disposed in the second bottom accommodating cavity. The second upper accommodating cavity, the second middle accommodating cavity, and the second bottom accommodating cavity are independently disposed and form a three-layer structure.

[0012] Furthermore, the fourth elastic filling material is hollow fiber, the fifth elastic filling material is memory foam, and the sixth elastic filling material is polyurethane foam.

[0013] Furthermore, one side of the pillow body is provided with an opening and closing mechanism for connecting the accommodating cavity and the outside.

[0014] Furthermore, the opening and closing mechanism includes a first sealing zipper, a second sealing zipper, and a third sealing zipper. The first sealing zipper extends from the second upper accommodating cavity toward the first upper accommodating cavity, the second sealing zipper extends from the second middle accommodating cavity toward the first middle accommodating cavity, and the third sealing zipper extends from the second bottom accommodating cavity toward the first bottom accommodating cavity.

[0015] Furthermore, the accommodating cavity is provided with an encapsulation body for encapsulating the elastic filling component.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features a detachable support body located below the accommodating cavity near the neck support area. This allows users to easily remove or insert the support body according to their actual needs, such as cervical curvature or sleeping posture, thereby enabling free adjustment of the pillow's firmness. This improves the flexibility and practicality of the pillow and effectively solves the problem that existing support rods are often fixed inside the pillow core, preventing users from flexibly adjusting or removing them according to their needs, which seriously affects the user experience.

[0024] Figure 6 This is the third schematic diagram of the structure of the pillow body of this utility model. Detailed Implementation

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 6 The zero-pressure pillow with built-in neck support shown includes a pillow body 1. The pillow body 1 includes a neck support area 2 for supporting the neck, a headrest area 3 for supporting the head and connected to the neck support area 2, a receiving cavity 4 located inside the pillow body 1, and a support body 5. The receiving cavity 4 is provided with an elastic filling component, and the support body 5 is detachably disposed below the receiving cavity 4 on the side near the neck support area 2.

[0027] This invention features a detachable support body located below the accommodating cavity near the neck support area. This allows users to easily remove or insert the support body according to their actual needs, such as cervical curvature or sleeping posture, thereby enabling free adjustment of the pillow's firmness. This improves the flexibility and practicality of the pillow and effectively solves the problem that existing support rods are often fixed inside the pillow core, preventing users from flexibly adjusting or removing them according to their needs, which seriously affects the user experience.

[0028] Furthermore, the support body 5 is positioned below the accommodating cavity 4 on the side near the neck support area 2, cleverly meeting the different support needs of the neck and head during sleep. Because the neck support area 2 is relatively firm due to the presence of the support body 5, it can precisely conform to the curve of the neck, providing strong and stable support for the neck, which helps to distribute neck pressure and relieve neck fatigue, and helps to ensure that the cervical spine maintains its natural physiological curvature during sleep. Secondly, the headrest area 3 is relatively soft, which can gently wrap the head, bringing a comfortable touch, effectively reducing pressure points on the head, and allowing the head to relax more during sleep.

[0029] Optionally, in some embodiments, the accommodating cavity 4 is provided with a mounting groove and a Velcro strap on the side near the neck support area 2. The Velcro strap is provided with a first adhesive surface on the side near the mounting groove. The support body 5 is installed in the mounting groove, and the end of the support body 5 is provided with a second adhesive surface that cooperates with the first adhesive surface. The support body 5 is installed in the mounting groove by the adhesion of the Velcro strap.

[0030] Optionally, in some embodiments, the accommodating cavity 4 is provided with an installation groove on the side near the neck support area 2. The installation groove is provided with a female magnetic buckle, and the surface of the support body 5 is provided with a female magnetic buckle. The support body 5 is installed in the installation groove by the attraction of the magnetic buckle. The user only needs to align the female buckle of the support body 5 with the female buckle and press it gently to complete the installation. When the user needs to disassemble, he / she only needs to pull it gently.

[0031] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the pillow body 1 is provided with an installation channel 11 extending along the neck support direction, the installation channel 11 penetrating the pillow body 1, and the support body 5 extending into the installation channel 11 to limit the installation position of the support body 5 on the pillow body 1.

[0032] like Figures 1 to 6 The pillow body 1 shown is provided with an installation channel 11 extending along the neck support direction. The installation channel 11 passes through the pillow body 1, and the support body 5 extends into the installation channel 11 to limit the installation position of the support body 5 on the pillow body 1.

[0033] Furthermore, the installation channel 11 extends along the neck support direction and passes through the pillow body 1, providing a clear and fixed installation path for the support body 5. After the support body 5 extends into the installation channel 11, it can be precisely positioned close to the neck support area 2 and conform to the physiological curve of the human neck. During the user's sleep, the support body 5 is not prone to lateral or longitudinal displacement, which is conducive to providing stable and precise support for the neck, helping to ensure that the neck maintains its natural physiological curvature during sleep and effectively reducing neck pressure.

[0034] Furthermore, since the installation channel 11 runs through the pillow body 1, the user can easily insert the support 5 into the installation channel 11 from one end of the pillow body 1 until the support 5 reaches the predetermined position, which greatly simplifies the installation process. The user can complete the installation of the support 5 without opening the receiving cavity 4 inside the pillow. Secondly, the user can also easily remove the support 5 from one end of the pillow body 1, which is convenient for cleaning, replacing or adjusting the support 5. The detachable setting provides great convenience to the user, making the maintenance and personalized adjustment of the pillow body 1 simpler.

[0035] Optionally, in some embodiments, the bottom of the mounting channel 11 is directly connected to the outside, and both ends extending along the neck support direction are also connected to the outside. Users can cover the pillow body 1 on the support body 5 from top to bottom, or they can choose to extend the support body 5 into the mounting channel 11 in the horizontal direction. Since both ends and the bottom of the mounting channel 11 are connected to the outside, users can easily remove the support body 5 for cleaning or replacement.

[0036] Optionally, in some embodiments, the mounting channel 11 is connected to the outside only at both ends extending along the neck support direction, and the bottom is not connected to the outside. The user can only insert the support body 5 into the mounting channel 11 in the horizontal direction. Since the bottom of the mounting channel 11 is closed, the position of the support body 5 inside the pillow is more stable and will not easily slip out due to the pillow being flipped or moved.

[0037] like Figures 1 to 6 The accommodating cavity 4 shown includes a first accommodating cavity 41 located below the neck support area 2 and a second accommodating cavity 42 located below the headrest area 3. The first accommodating cavity 41 and the second accommodating cavity 42 are independently arranged.

[0038] Furthermore, the first cavity 41 can independently hold high-density filling material to ensure stable support for the neck and prevent the cervical spine from being suspended during sleep, while the second cavity 42 can be filled with soft materials such as low-resilience sponge and down to allow the head to sink naturally, reduce ear pressure, and avoid head discomfort caused by the diffusion of the support body's hardness in traditional one-piece cavities.

[0039] Furthermore, users can adjust the filling materials in the first accommodating cavity 41 and the second accommodating cavity 42 according to their actual needs. For example, users can choose filling materials with different hardness according to their own neck curves, and at the same time, they can choose head filling materials of different materials according to their actual needs, thereby achieving a personalized sleep experience.

[0040] Furthermore, since the first accommodating cavity 41 and the second accommodating cavity 42 are independent of each other, the user can remove the elastic filling components (not shown in the figure) in the two accommodating cavities for cleaning or replacement, making the cleaning and maintenance of the pillow body 1 more convenient, effectively reducing the growth of bacteria and mites, and effectively extending the service life of the pillow body 1.

[0041] Furthermore, if the elastic filling component in the first accommodating cavity 41 or the second accommodating cavity 42 is damaged and needs to be replaced, the user can replace the elastic filling component in the accommodating cavity 4 alone without replacing the entire pillow, which helps to reduce the cost of use.

[0042] like Figures 1 to 6 The first accommodating cavity 41 shown includes a first upper accommodating cavity 411 located near the neck brace area 2, a first bottom accommodating cavity 413 located near the support body 5, and a first middle accommodating cavity 412 located between the first upper accommodating cavity 411 and the first bottom accommodating cavity 413. The elastic filling assembly includes a first elastic filling material disposed in the first upper accommodating cavity 411, a second elastic filling material disposed in the first middle accommodating cavity 412, and a third elastic filling material disposed in the first bottom accommodating cavity 413. The first upper accommodating cavity 411, the first middle accommodating cavity 412, and the first bottom accommodating cavity 413 are independently disposed and form a three-layer structure.

[0043] Furthermore, by setting three independent cavities 4 within the first accommodating cavity 41, more precise zoned support can be provided for the neck. The first bottom accommodating cavity 413 is close to the support body 5, and the third elastic filling material (not shown in the figure) can be a relatively hard material to provide stable support for the neck. The second elastic filling material (not shown in the figure) in the first middle accommodating cavity 412 can be a medium-hard material to play a role in buffering and transition. The first upper accommodating cavity 411 is close to the neck support area 2, and the first elastic filling material (not shown in the figure) can be a relatively soft material to provide a comfortable touch for the neck.

[0044] Furthermore, users can choose elastic filling materials with different hardness and materials according to their needs and preferences. For example, users who need stronger support can fill the first bottom cavity 413 with a harder elastic filling material; users who prefer a soft touch can fill the first upper cavity 411 with a softer elastic filling material.

[0045] Furthermore, since the three accommodating cavities 4 are independent of each other, friction and wear between the elastic filling materials can be reduced, which helps to extend the service life of the elastic filling materials and effectively maintain the support and comfort of the pillow body 1.

[0046] like Figures 1 to 6 The first elastic filler material shown is polyurethane foam, the second elastic filler material is memory foam, and the third elastic filler material is latex particle filler.

[0047] Furthermore, polyurethane foam has good elasticity and breathability, providing a soft touch while maintaining a certain degree of support. Polyurethane foam can quickly respond to neck movements, providing immediate comfort. As the elastic filling material of the first upper accommodating cavity 411, polyurethane foam can provide a soft contact surface for the neck, reducing neck pressure while maintaining good breathability and avoiding stuffiness.

[0048] Furthermore, memory foam has slow rebound properties, which can automatically adjust to the shape of the neck to provide precise support. Memory foam can disperse pressure and reduce the problem of excessive local stress. At the same time, it has good heat insulation properties. As the elastic filling material of the first central cavity 412, memory foam can play a role in buffering and transition, further dispersing the pressure on the neck and providing more even support. Secondly, memory foam can automatically adjust to the user's neck curve, which is conducive to providing a stable support effect.

[0049] Furthermore, latex particles have high elasticity and breathability, providing stable support. The particle structure of latex particles can disperse pressure while maintaining good breathability and antibacterial properties. As the elastic filling material of the first bottom cavity 413, latex particles can provide stable support for the neck, ensuring that the bottom structure of the pillow is solid and reliable. Latex particles can effectively disperse neck pressure while maintaining the pillow's breathability and antibacterial properties.

[0050] Furthermore, polyurethane foam provides a soft touch, memory foam provides precise support, and latex particles provide stable bottom support. This combination combines the advantages of multiple materials to achieve progressive support from softness to stability.

[0051] like Figures 1 to 6The second accommodating cavity 42 shown includes a second upper accommodating cavity 421 located near the headrest region 3, a second bottom accommodating cavity 423 adjacent to the first bottom accommodating cavity 413, and a second middle accommodating cavity 422 located between the second upper accommodating cavity 421 and the second bottom accommodating cavity 423. The elastic filling assembly includes a fourth elastic filling material disposed in the second upper accommodating cavity 421, a fifth elastic filling material disposed in the second middle accommodating cavity 422, and a sixth elastic filling material disposed in the second bottom accommodating cavity 423. The second upper accommodating cavity 421, the second middle accommodating cavity 422, and the second bottom accommodating cavity 423 are independently disposed and form a three-layer structure.

[0052] Furthermore, the second accommodating cavity 42 is located below the headrest area 3. Through its layered design, it can provide more precise zoned support for the head. The second bottom accommodating cavity 423 is close to the first bottom accommodating cavity 413 and can be filled with a firmer elastic filling material to provide stable support for the head. The second middle accommodating cavity 422 can be filled with a medium-firm elastic filling material to provide cushioning and transition. The second upper accommodating cavity 421 is close to the headrest area 3 and can be filled with a softer elastic filling material to provide a comfortable feel for the head.

[0053] Furthermore, by filling different elastic filling materials in different layers, the pillow body 1 can simultaneously meet the head's support and comfort needs. The second upper cavity 421 provides a soft contact surface, the second middle cavity 422 plays a buffering role, and the second bottom cavity 423 provides stable support, thereby achieving progressive support from soft to stable.

[0054] Furthermore, the three independently arranged cavities 4 and different elastic filling materials can better disperse the pressure on the head. When the head rests on the pillow, the pressure is first initially dispersed by the fourth elastic filling material (not shown in the figure) of the second upper cavity 421, then further buffered by the fifth elastic filling material (not shown in the figure) of the second middle cavity 422, and finally provided with stable support by the sixth elastic filling material (not shown in the figure) of the second bottom cavity 423.

[0055] like Figures 1 to 6 The fourth elastic filling material shown is hollow fiber, the fifth elastic filling material is memory foam, and the sixth elastic filling material is polyurethane foam;

[0056] Furthermore, hollow fibers possess excellent fluffiness, breathability, and warmth, providing a soft touch while maintaining the lightness of the pillow body 1. The hollow structure of the hollow fibers can retain air, regulate the humidity inside the pillow, and keep it dry. As the elastic filling material of the second upper accommodating cavity 421, hollow fibers can provide a soft contact surface for the head, reducing pressure on the head while maintaining good breathability and avoiding stuffiness.

[0057] Furthermore, memory foam has slow rebound properties, which can automatically adjust to the shape of the head to provide precise support. Memory foam can disperse pressure and reduce the problem of excessive local pressure. At the same time, it has good heat insulation properties. As the elastic filling material of the second central cavity 422, memory foam can play a role in buffering and transition, further dispersing the pressure on the head and providing more even support. Memory foam can automatically adjust according to the user's head curve to ensure personalized support effect.

[0058] Furthermore, polyurethane foam has good elasticity and support, providing stable bottom support. It can maintain the shape of the pillow and is not easily deformed, while also having good breathability. As the filling material of the second bottom cavity 423, polyurethane foam can provide stable support for the head, ensuring that the bottom structure of the pillow is solid and reliable. Polyurethane foam can effectively distribute the pressure on the head while maintaining the breathability and antibacterial properties of the pillow.

[0059] Furthermore, hollow fiber, memory foam, and polyurethane foam are located in different parts of the second accommodating cavity 42, forming a multi-layered support structure. Hollow fiber provides light and fluffy initial support, memory foam achieves personalized support that precisely conforms to the head shape, and polyurethane foam provides solid bottom support. This multi-layered support can better meet the support needs of the head under different pressures and positions, and improve the accuracy and effectiveness of the support.

[0060] like Figures 1 to 6 The pillow body 1 shown is provided with an opening and closing mechanism 6 on one side for connecting the accommodating cavity 4 and the outside;

[0061] Furthermore, the opening and closing mechanism 6 allows users to easily open the pillow body 1 and directly access the receiving cavity 4, thereby facilitating the removal or insertion of the elastic filling component, which is beneficial for users to regularly replace or adjust the elastic filling component.

[0062] Furthermore, the opening and closing mechanism 6 makes it easier to clean the inside of the pillow body 1. Users can open the pillow regularly, remove the elastic filling components, and thoroughly clean and air the inside of the pillow to keep it hygienic and fresh.

[0063] Optionally, in some embodiments, the opening and closing mechanism 6 includes a Velcro strip disposed on one side of the pillow body 1. The Velcro strip consists of a loop side and a hook side, which are respectively fixed on both sides of the opening of the receiving cavity 4. The user can tear the hook side of the Velcro strip from the loop side to expose the opening of the receiving cavity 4, making it convenient to take out or put in the elastic filling component, or re-attach the hook side of the Velcro strip to the loop side to seal the receiving cavity 4 and prevent the elastic filling component from leaking out.

[0064] Optionally, in some embodiments, the opening and closing mechanism 6 includes a snap button disposed on one side of the pillow body 1. The snap button consists of a female snap button and a female snap button, which are respectively fixed on both sides of the opening of the receiving cavity 4. The user can gently press the female snap button to make it pop out from the female snap button, thereby exposing the opening of the receiving cavity 4, making it convenient to take out or put in the elastic filling component. Alternatively, the user can press the female snap button down again to make it fasten with the female snap button, thereby sealing the receiving cavity 4 and preventing the elastic filling component from leaking out.

[0065] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the opening and closing mechanism 6 includes a zipper disposed on one side of the pillow body 1.

[0066] like Figures 1 to 6 The opening and closing mechanism 6 shown includes a first sealing zipper 61, a second sealing zipper 62, and a third sealing zipper 63. The first sealing zipper 61 extends from the second upper receiving cavity 421 toward the first upper receiving cavity 411. The second sealing zipper 62 extends from the second middle receiving cavity 422 toward the first middle receiving cavity 412. The third sealing zipper 63 extends from the second bottom receiving cavity 423 toward the first bottom receiving cavity 413.

[0067] Furthermore, the first sealing zipper 61, the second sealing zipper 62, and the third sealing zipper 63 correspond to different receiving cavities 4. Users can open or close the corresponding receiving cavities 4 independently without affecting other parts, so that users can adjust the elastic filling components in each receiving cavity 4 individually without having to process the entire pillow body 1 at the same time.

[0068] Furthermore, the first sealing zipper 61, the second sealing zipper 62, and the third sealing zipper 63 each correspond to different areas of the receiving cavity 4. The first sealing zipper 61 corresponds to the upper receiving cavity, the second sealing zipper 62 corresponds to the middle receiving cavity, and the third sealing zipper 63 corresponds to the bottom receiving cavity. During operation, the user can quickly and accurately locate the receiving cavity 4 that needs to be opened or closed, without having to fumble around in a large opening to find a specific area, greatly improving the convenience and efficiency of the operation.

[0069] Furthermore, during pillow use, some areas may get dirty more easily than others. The three-zipper design allows users to open only the compartments that need cleaning and perform spot cleaning on those areas.

[0070] like Figures 1 to 6 The cavity 4 shown is provided with an encapsulation body for encapsulating the elastic filling component;

[0071] Furthermore, the encapsulation body (not shown in the figure) can encapsulate the elastic filling components, such as memory foam, polyurethane foam, latex particles, etc., to prevent the elastic filling components from scattering or shifting during use. This not only keeps the inside of the pillow body 1 clean, but also prevents the elastic filling components from being damaged by friction.

[0072] Furthermore, the encapsulation can effectively isolate dust, bacteria, and mites, reducing contamination of the elastic filling components. Users can periodically remove the encapsulation for cleaning or replacement, thereby keeping the pillow body 1 hygienic and fresh.

[0073] Optionally, the encapsulation body includes a cotton cloth encapsulation body. Cotton cloth has good breathability, which can keep the inside of the pillow dry and reduce stuffiness. Secondly, cotton cloth can be machine washed or hand washed, making it easy to clean and suitable for frequent washing.

[0074] Optionally, the encapsulation body includes a bamboo fiber encapsulation body. Bamboo fiber has natural antibacterial properties, which can effectively inhibit the growth of bacteria and mites and keep the pillow hygienic. Secondly, bamboo fiber has better breathability and moisture absorption than ordinary cotton cloth, which can quickly absorb and release moisture and keep the inside of the pillow dry.

[0075] Optionally, the encapsulation body includes a polyester fiber encapsulation body. Polyester fibers have high strength and abrasion resistance, long service life, and are not easily deformed. Secondly, polyester fibers have good elasticity, which can maintain the shape of the pillow and provide stable support.

[0076] The implementation method of Example 1 is as follows:

[0077] A zero-pressure pillow with built-in neck support includes a pillow body 1. The pillow body 1 includes a neck support area 2 for supporting the neck, a headrest area 3 for supporting the head and connected to the neck support area 2, a receiving cavity 4 located inside the pillow body 1, and a support body 5. The receiving cavity 4 is provided with an elastic filling component, and the support body 5 is detachably disposed below the side of the receiving cavity 4 near the neck support area 2.

[0078] This invention features a detachable support body located below the accommodating cavity near the neck support area. This allows users to easily remove or insert the support body according to their actual needs, such as cervical curvature or sleeping posture, thereby enabling free adjustment of the pillow's firmness. This improves the flexibility and practicality of the pillow and effectively solves the problem that existing support rods are often fixed inside the pillow core, preventing users from flexibly adjusting or removing them according to their needs, which seriously affects the user experience.

The Velcro is provided with a first adhesive surface on the side near the installation groove. The support body 5 is installed in the installation groove, and the end of the support body 5 is provided with a second adhesive surface that cooperates with the first adhesive surface. The support body 5 is installed in the installation groove by the adhesion of the Velcro.

[0099] The implementation method of Example Twelve is as follows:

[0100] The difference between Example 12 and Example 2 is that: the accommodating cavity 4 is provided with an installation groove on the lower side near the neck support area 2, and the installation groove is provided with a female magnetic buckle, and the surface of the support body 5 is provided with a male magnetic buckle. The support body 5 is installed in the installation groove by the attraction of the magnetic buckle. The user only needs to align the male buckle of the support body 5 with the female buckle and press it gently to complete the installation. When the user needs to disassemble, he / she only needs to pull it open gently.

[0101] The implementation method of Example Thirteen is as follows:

[0102] The difference between Embodiment Thirteen and Embodiment Nine is that the opening and closing mechanism 6 includes a Velcro attached to one side of the pillow body 1. The Velcro consists of a loop side and a hook side, which are fixed on both sides of the opening of the receiving cavity 4. The user can tear the hook side of the Velcro from the loop side to expose the opening of the receiving cavity 4, making it convenient to take out or put in the elastic filling component. Alternatively, the user can re-attach the hook side of the Velcro to the loop side to seal the receiving cavity 4 and prevent the elastic filling component from leaking out.

[0103] The implementation method of Example Fourteen is as follows:

[0104] The difference between Embodiment Fourteen and Embodiment Nine is that the opening and closing mechanism 6 includes a snap button located on one side of the pillow body 1. The snap button consists of a female snap button and a female snap button, which are fixed on both sides of the opening of the receiving cavity 4. The user can gently press the female snap button to pop it out from the female snap button, thereby exposing the opening of the receiving cavity 4, making it convenient to take out or put in the elastic filling component. Alternatively, the user can press the female snap button down again to make it engage with the female snap button, thereby sealing the receiving cavity 4 and preventing the elastic filling component from leaking out.
