Description

Technical Field

[0001] This utility model relates to the field of bedding technology, and in particular to a detachable and modular pillow. Background Technology

[0002] As an important piece of bedding, the core function of a pillow is to provide adequate support for the head and neck, maintaining the natural physiological curve of the spine during sleep, thereby ensuring sleep quality and physical health. Traditional pillows are mostly filled with a single material, such as synthetic fibers, memory foam, latex, or down, resulting in a uniform and fixed sleeping experience. However, due to significant individual differences in body shape, sleeping posture preferences (such as supine or side-lying), and subjective feelings about firmness, pillows with a single sleeping experience cannot meet the personalized needs of all users.

[0003] To address this limitation, dual-feel pillows have emerged in the market in recent years. These products typically combine two materials with different properties; for example, one side might be firm memory foam providing strong support, while the other side uses soft latex particles to enhance conformability; or they might employ a zoned design, making one side of the pillow more suitable for back sleeping and the other more suitable for side sleeping. This design, to some extent, enriches user choices and provides initial adaptability.

[0004] However, existing dual-feel pillows still have significant drawbacks. The biggest problem is that the combination of the two feel options is pre-fixed, non-removable, and cannot be adjusted. Users can only passively choose between two pre-set feel options, unable to freely combine and create according to their own needs. For example, if a user wants to try an effect other than the preset "medium-soft" or "extra firm," they cannot. This fixed model limits the product's personalization and flexibility, failing to truly meet the dynamically changing needs of users (such as different support requirements due to seasonal changes or changes in physical condition), essentially remaining another form of "standardized" product.

[0005] Therefore, existing dual-feel pillows need to be improved to solve the problem that the sleeping feel on both sides is fixed and cannot be adjusted, and users cannot freely combine and match the softness and firmness according to their personal needs.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a detachable and modular pillow that solves the problem that the sleeping feel of existing dual-feel pillows is fixed and cannot be adjusted on both sides, preventing users from freely combining and matching the softness and firmness according to their personal needs.

[0008] To achieve the above objectives, this utility model provides a detachable and splicable pillow, including a first pillow body and a second pillow body with a concave groove at one end;

[0009] One end of the first pillow body is detachably connected to the recessed groove, and the other end of the first pillow body protrudes toward the second pillow body and covers the end face of the other end of the second pillow body.

[0010] Optionally, the first pillow body has an L-shaped structure and the second pillow body has a J-shaped structure.

[0011] Optionally, the J-shaped structure includes a horizontal support portion of the J-pillow and a longitudinal portion of the J-pillow fixed to one end of the horizontal support portion of the J-pillow; wherein the longitudinal portion of the J-pillow protrudes relative to the horizontal support portion of the J-pillow toward the side where the first pillow body is located and forms the concave groove.

[0012] Optionally, the L-shaped structure includes an L-pillow horizontal support portion that fits against the J-pillow horizontal support portion and has one end inserted into the concave groove, and an L-pillow longitudinal portion fixed to the other end of the L-pillow horizontal support portion; wherein the L-pillow longitudinal portion protrudes relative to the L-pillow horizontal support portion toward the side where the second pillow body is located and covers the end face of the J-pillow horizontal support portion away from the J-pillow longitudinal portion.

[0013] The side seams of the optional J-pillow horizontal support and L-pillow horizontal support can be detachably connected by a zipper.

[0014] Optionally, both the first pillow body and the second pillow body include a pillow core and a pillowcase fitted over the pillow core;

[0015] Furthermore, the pillow cores of the two pillow bodies have different hardness, and / or the pillowcases of the two pillow bodies have different fabrics.

[0016] Optionally, the pillow core of the first pillow body is a soft support pillow core made of sponge, and the fabric of the pillowcase of the first pillow body away from the second pillow body is a skin-friendly fiber fabric.

[0017] The second pillow body has a memory foam core that provides firm support, and the pillowcase of the second pillow body has a cool-feeling nylon fabric on the side away from the first pillow body.

[0018] Optionally, the fabric of the pillowcase of the first pillow body near the side of the second pillow body, and / or the fabric of the pillowcase of the second pillow body near the side of the first pillow body, is a non-slip fabric.

[0019] Optionally, the pillowcases of the two pillow bodies may be different colors.

[0020] Optionally, the first pillow body and the recessed groove are connected by an interference fit.

[0021] The beneficial effects of this utility model are as follows: It provides a detachable and connectable pillow. During assembly, the user directly and precisely inserts one end of the first pillow body into the concave groove of the second pillow body. This insertion action completes the initial positioning and fixation of the two pillow bodies in the horizontal direction. Immediately afterwards, the other end of the first pillow body will naturally cover the end face of the other end of the second pillow body. This "one end inserted, the other end covered" design constitutes a stable and reliable physical connection, allowing the two originally independent pillow bodies to be combined into a seamless, integrated, complete pillow.

[0022] Users can freely disassemble, exchange, or replace pillows with different firmness and materials based on their sleeping habits (such as different needs for pillow height when sleeping on their back or side), physical condition (such as needing firmer support when experiencing neck discomfort), or seasonal changes (such as preferring a cool touch in summer). This fundamentally solves the pain point of existing dual-feel pillows that have a "fixed and unadjustable sleeping feel," completely returning the choice to the user and achieving true personalized customization.

[0023] Therefore, the detachable and splicable pillow provided by this utility model can solve the problem that the sleeping feel of the two sides of the existing dual-feel pillow is fixed and cannot be adjusted, and users cannot freely combine and match the softness and firmness according to their personal needs.

[0039] This invention provides a detachable and modular pillow that solves the problem that the sleeping feel of existing dual-feel pillows is fixed and cannot be adjusted on both sides, preventing users from freely combining and matching the softness and firmness according to their personal needs.

[0040] See Figure 1 and Figure 2 The detachable and splicable pillow provided in this embodiment includes a first pillow body 1 and a second pillow body 2 with a concave groove 2021 at one end;

[0041] One end of the first pillow body 1 is detachably connected to the recessed groove 2021, and the other end of the first pillow body 1 protrudes toward the second pillow body 2 and covers the end face of the other end of the second pillow body 2.

[0042] The core concept of this utility model is to create a modular, dual-sleep-feel pillow through a unique "insertion and covering" structure.

[0043] During assembly, the user directly and precisely inserts one end of the first pillow body 1 into the recessed groove 2021 of the second pillow body 2. This insertion action completes the initial positioning and fixation of the two pillow bodies in the horizontal direction. Immediately afterwards, the other end of the first pillow body 1 will naturally cover the other end face of the second pillow body 2. This "one end inserted, the other end covered" design constitutes a stable and reliable physical connection, allowing the two originally independent pillow bodies to be combined into a seamless, integrated complete pillow.

[0044] First, this modular design achieves complete modularity for the pillow. Users can freely disassemble, exchange, or replace pillow bodies with different firmness and materials based on their sleeping habits (such as different needs for pillow height when sleeping on their back or side), physical condition (such as needing firmer support when experiencing neck discomfort), or seasonal changes (such as preferring a cool feel in summer). This fundamentally solves the pain point of existing dual-feel pillows where the "sleep feel is fixed and cannot be adjusted," completely returning the choice to the user and achieving true personalized customization.

[0045] Secondly, the "covered end face" design has multiple advantages. First, it visually hides the seams, making the assembled pillow appear neat and seamless, enhancing the product's aesthetics and premium feel. Second, functionally, it eliminates any gaps that might appear at the joint between the two pillow bodies, effectively preventing discomfort caused by the head slipping into the gap during sleep and avoiding the risk of hair getting caught, significantly improving safety and comfort. Third, this overlapping structure enhances the longitudinal stability of the pillow body connection, preventing the two pillow bodies from shifting vertically or separating during use.

[0046] Therefore, the detachable and splicable pillow provided by this utility model can solve the problem that the sleeping feel of the two sides of the existing dual-feel pillow is fixed and cannot be adjusted, and users cannot freely combine and match the softness and firmness according to their personal needs.

[0047] Optionally, the first pillow body 1 and the recessed groove 2021 are connected by an interference fit. When assembling the pillow bodies, the user needs to apply a certain amount of pressure to fully embed one end of the first pillow body 1 into the recessed groove 2021 of the second pillow body 2, utilizing the elastic deformation of the material itself to generate a slight compressive force. This interference fit forms a tight physical connection between the pillow bodies, effectively preventing accidental loosening or misalignment due to head rotation or turning over during use, further enhancing the integrity and stability of the spliced ​​structure. Compared to connection methods such as snaps and hook and loop fasteners, the interference fit requires no additional parts, has a simple and reliable structure, high durability, and avoids the discomfort that may be caused by rigid connectors.

[0048] In this embodiment, the first pillow body 1 has an L-shaped structure, and the second pillow body 2 has a J-shaped structure. Specifically:

[0049] The J-shaped structure includes a horizontal support portion 201 for the J-pillow and a longitudinal portion 202 for the J-pillow fixed to one end of the horizontal support portion 201; wherein the longitudinal portion 202 protrudes relative to the horizontal support portion 201 toward the side where the first pillow body 1 is located, and forms the concave groove 2021.

[0050] The L-shaped structure includes an L-pillow horizontal support portion 101 that fits against the J-pillow horizontal support portion 201 and has one end inserted into the recessed groove 2021, and an L-pillow longitudinal portion 102 fixed to the other end of the L-pillow horizontal support portion 101; wherein, the L-pillow longitudinal portion 102 protrudes relative to the L-pillow horizontal support portion 101 toward the side where the second pillow body 2 is located, and covers the end face of the J-pillow horizontal support portion 201 away from the end of the J-pillow longitudinal portion 202.

[0051] It's worth noting that the L-shaped and J-shaped pillows resemble jigsaw puzzle pieces, allowing them to fit together naturally. During operation, the longitudinal sections of the L-shaped and J-shaped pillows interlock, creating an interlocking effect that effectively prevents the pillows from shifting or separating during sleep. This structural design increases the contact area and enhances connection stability. This makes the detachable, interlocking pillow more stable overall; even if the user turns over or adjusts their sleeping position, the pillow will not loosen, ensuring a continuous and comfortable sleep experience.

[0052] Furthermore, the interlocking L-shaped and J-shaped structures, combined with specific usage methods, ensure that the neck is always supported at the correct corner. Specifically, users need to "flip up and down" to select the desired sleeping position (either the first pillow body 1 or the second pillow body 2 facing upwards), and simultaneously "turn around" (i.e., reverse the pillow's direction so that the end originally facing the head of the bed faces the foot of the bed). This ensures that regardless of which sleeping position is facing upwards, the user's neck is always supported at the corner area formed by the longitudinal and horizontal support parts of the currently facing pillow body (either the first pillow body 1 or the second pillow body 2). This fundamentally solves the discomfort problem that may exist at the seams of spliced ​​pillows.

[0053] In other words, the detachable and modular pillow has two usage modes:

[0054] (1) State 1 (first occipital body 1 facing upward)

[0055] In this state, the user's neck pillow rests against the L-shaped corner area formed by the horizontal support part 101 and the longitudinal part 102 of the L-pillow. This core support area is completely formed independently by the first pillow body 1 (L-shaped structure), seamlessly integrated without any joints.

[0056] Regarding the seam between the longitudinal portion 202 of the J pillow and the horizontal support portion 101 of the L pillow: This seam is located at the end of the pillow furthest from the user's body (such as the headboard). During normal sleep, the user's head will not come into contact with this distal area.

[0057] Regarding the seam between the horizontal support part 201 of the J pillow and the longitudinal part 102 of the L pillow: This seam is located on the side of the pillow, directly below the user's neck. However, since this seam is actually located below the first pillow body 1 (L-shaped structure), it is completely blocked by the L pillow body above, and the user's neck cannot directly contact it.

[0058] (2) State 2 (Second occipital body 2 upward)

[0059] In this state, the user's neck pillow rests against the J-shaped corner area formed by the horizontal support part 201 and the longitudinal part 202 of the J-pillow. This core support area is completely formed independently by the second pillow body 2 (J-shaped structure), seamlessly integrated without any joints.

[0060] Regarding the seam between the longitudinal portion 102 of the L-pillow and the horizontal support portion 201 of the J-pillow: This seam is located at the end of the pillow furthest from the user's body (such as the headboard). During normal sleep, the user's head will not come into contact with this distal area.

[0061] Regarding the seam between the horizontal support part 101 of the L-pillow and the longitudinal part 202 of the J-pillow: This seam is located on the side of the pillow, directly below the user's neck. However, since this seam is actually located below the second pillow body 2 (J-shaped structure), it is completely blocked by the J-pillow body above, and the user's neck cannot directly contact it.

[0062] In summary, the core advantage of this design lies in the fact that, through the physical structure of "L-shaped and J-shaped interlocking" combined with the usage logic of "flipping and turning around", no matter which sleeping feel is selected, all seams are cleverly isolated in non-functional areas (the far end of the pillow or the back of another pillow body) that the user's body cannot directly contact, thus always ensuring the integrity of the core support area and a seamless comfort experience.

[0063] In this embodiment, the side seams of the J-pillow horizontal support portion 201 and the L-pillow horizontal support portion 101 are detachably connected by a zipper 3. The sides of the two horizontal support portions do not require support and do not come into contact with the human body, so the zipper 3 is not used here and does not affect the user experience.

[0064] Specifically, users can quickly separate or connect the two pillowcases by pulling zipper 3, facilitating individual washing, drying, or replacement. Since the seam is located on the side of the pillow, this area does not directly contact the head or neck, and zipper 3 does not affect the feel during sleep. The zipper 3 connection method enhances maintainability; users can periodically remove the pillowcase for cleaning to maintain hygiene. At the same time, zipper 3 is hidden on the side, not affecting the aesthetics or function of the pillow's front and back. This design extends the pillow's lifespan and allows users to freely combine pillowcases made of different materials (such as warm fabric for winter and cooling fabric for summer).

[0065] In this embodiment, both the first pillow body 1 and the second pillow body 2 include a pillow core and a pillowcase fitted over the pillow core; and the pillow cores of the two pillow bodies have different hardness, and / or the pillowcases of the two pillow bodies have different fabrics.

[0066] Users can choose their desired sleeping feel by flipping the pillow or changing the pillow body: for example, a soft pillow core provides a snug fit, while a firm pillow core provides support; different fabrics offer different tactile sensations (such as smooth, cool, and skin-friendly). Through modular design, users can not only adjust the firmness but also customize the feel, truly achieving a personalized sleep experience. Specific material examples include pillow cores made of memory foam, latex, or sponge, while pillowcase fabrics can be made of cotton, nylon, Tencel, etc., meeting diverse needs.

[0067] As an optional implementation, the pillow core of the first pillow body 1 is a soft support pillow core made of sponge, and the fabric of the pillowcase of the first pillow body 1 on the side away from the second pillow body 2 is a skin-friendly fiber fabric.

[0068] The pillow core of the second pillow body 2 is a rigid support pillow core made of memory foam, and the fabric of the pillowcase of the second pillow body 2 on the side away from the first pillow body 1 is a cool-feeling nylon fabric.

[0069] Users can choose the soft sponge side for a gentle, enveloping feel when lying on their back, and the memory foam side for strong support when lying on their side; skin-friendly fabrics enhance comfort, while cooling fabrics are suitable for summer or users who are sensitive to heat. This combination balances support and breathability, with the lightweight and breathable sponge core and the slow-rebound memory foam core complementing each other; the differences in fabrics further optimize the feel and improve seasonal adaptability.

[0070] In this embodiment, the fabric of the pillowcase of the first pillow body 1 near the side of the second pillow body 2, and / or the fabric of the pillowcase of the second pillow body 2 near the side of the first pillow body 1, is an anti-slip fabric (such as a silicone dot coating or rubber material). When the two pillow bodies are joined together, the anti-slip fabric increases the coefficient of friction, preventing the pillow bodies from sliding relative to each other during sleep. This ensures the stability of the joined structure; even with prolonged use or frequent tossing and turning, the pillow bodies will not shift, maintaining the optimal support shape of the pillow. Simultaneously, the anti-slip design eliminates the need for additional fasteners, simplifying the structure.

[0071] Optionally, the pillowcases of the two pillow bodies can be different colors. Users can quickly and accurately identify the firmness of the pillow body facing upwards simply by the striking color difference, without needing to touch or try it, thereby improving product usability and user experience. For example, the pillowcase of the firmer pillow body 2 can be blue (a cool color, suggesting coolness and firmness), while the pillowcase of the softer pillow body 1 can be beige or pink (a warm color, suggesting warmth and softness). This color coding not only makes it easy for users to quickly select their desired sleeping feel, especially useful in low light conditions at night, but also enhances the product's aesthetics and personalization options.

[0072] In summary, this utility model has the following advantages:

[0073] ① Personalized Sleep Comfort Customization: Through the modular splicing design of the first pillow body 1 and the second pillow body 2, users can freely combine pillow bodies of different softness and firmness according to their personal needs, thus realizing personalized sleep comfort customization.

[0074] ② Stable and reliable connection: The interlocking structure of L-shaped and J-shaped pillow bodies that interlock and cover the end faces effectively prevents the pillow bodies from shifting or separating during sleep, ensuring the stability of use.

[0075] ③ Seamless experience in the core area: Through ingenious geometric design, it is ensured that the core support area for the neck is composed of a single, complete pillow body, regardless of the usage state, fundamentally eliminating the discomfort caused by seams.

[0076] ④ Easy to operate and maintain: By setting zippers 3 at the side seams, the pillow body can be quickly disassembled and assembled, making it convenient for users to clean, dry or replace parts, thus improving the maintainability of the product.

[0077] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
