Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to an adjustable pillow. Background Technology

[0002] People are accustomed to using pillows for sleeping and resting in bed. Traditional pillows consist of a pillow core and a pillowcase that covers the pillow core, with the pillow core filled with pillow material. An existing utility model patent, CN2561306Y, describes a segmented health pillow, which includes a pillowcase with multiple pillow cores placed spaced apart within the pillowcase. The pillow cores are low in the middle and high on the sides. However, the applicant has found that the drawback of existing pillows is that the cross-sectional dimensions of each segment of the pillow core are mostly uniformly designed, not adapted to the physiological needs of the human body, and unevenness easily occurs at the joints between adjacent pillow cores. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable pillow to solve the technical problem of poor adaptability in the prior art.

[0004] To solve the above problems, the adjustable pillow involved in this utility model adopts the following technical solution: This utility model provides an adjustable pillow, including a main pillowcase, a middle pillow, and two side pillows. The middle pillow and the two side pillows are all located inside the main pillowcase. The two side pillows are symmetrically arranged at both ends of the length direction of the middle pillow and are detachably connected to the adjacent ends of the middle pillow through a detachable connection structure. The middle pillow includes a middle pillowcase and middle pillow filling material inside the middle pillowcase. The middle pillowcase includes a middle section and an expanded diameter section integrally formed at both ends of the middle section. The expanded diameter section gradually expands in diameter away from the middle section. The cross-sectional dimension of the middle section is smaller than the cross-sectional dimension of the side pillowcase. The cross-sectional dimension of the expanded diameter section near the side pillow is adapted to the cross-sectional dimension of the side pillowcase. The side pillows include side pillowcases and side pillow filling material inside the side pillowcases. The side pillows are provided with side pillow openings that allow the side pillow filling material to enter and exit. The middle pillow is provided with a middle pillow opening that allows the middle pillow filling material to enter and exit. The main pillowcase is provided with main pillow openings that allow the middle pillow and the side pillows to enter and exit respectively.

[0005] Preferably, the detachable connection structure includes a first connecting part located at the end of the expanded diameter section and a second connecting part located at the corresponding end of the side pillow. The first connecting part and the second connecting part are detachably coupled. The first connecting part is a Velcro female or a snap fastener female, and the second connecting part is a Velcro female that is adapted to the Velcro female or a snap fastener female that is adapted to the snap fastener female.

[0006] Preferably, the side pillow opening, the middle pillow opening, and the main pillow opening are all provided with closure components to control their opening and closing. The closure components are zippers, snap fasteners, buttons, or magnetic snaps.

[0007] Preferably, one end of the side pillow is provided with an annular surface that extends circumferentially along its end face edge and is connected end to end. The end of the expanded diameter section of the middle pillow near the side pillow can be matched and located in the cavity formed by the annular surface, and the outer wall of the expanded diameter section is in contact with the inner wall of the annular surface. The first connecting part is provided on the end peripheral wall of the expanded diameter section embedded in the cavity, and the second connecting part is provided on the inner peripheral wall of the cavity. When the expanded diameter section is located in the cavity, the first connecting part and the second connecting part are correspondingly matched to achieve a detachable connection.

[0008] The beneficial effects of this utility model are as follows: This utility model provides an adjustable pillow that differs from existing technologies in that it achieves detachable connection between the center pillow and the side pillows through a detachable connection structure. Users can remove one or both side pillows according to their shoulder width, or replace the filling of a single pillow body. The gradually expanding diameter structure of the center pillow, combined with the cross-sectional size adaptation design of the expanding section and the side pillows, creates a smooth transition at the connection between the center pillow and the side pillows. Users can also detach or connect the pillows at any time according to their needs, making it convenient to carry. Attached Figure Description

[0009] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below: Figure 1 This is a structural diagram showing the interlocking relationship between the individual pillow sections of an adjustable pillow. In the diagram: 1. Main pillowcase; 2. Middle pillow; 21. Expanded section; 22. Middle section; 3. Side pillow. Detailed Implementation
