Description

Technical Field

[0001] This utility model relates to the field of pillow core technology, specifically a pull-out adjustable pillow core. Background Technology

[0002] There are many types of pillows available, with diverse shapes and materials. However, people vary in height, weight, and body shape. Most traditional pillow cores are not height-adjustable after sewing and filling, which means that the needs of different people cannot be met.

[0003] To accommodate different body shapes and sleeping positions, an adjustable pillow with an air bladder has been developed. This pillow core contains an air-conducting hose and an air bladder, allowing the pillow's height to be adjusted by inflating the air bladder. However, these pillow cores have relatively complex structures, making the adjustment process cumbersome and inconvenient when the pillow's height needs to be adjusted during sleep. Therefore, those skilled in the art have developed a pull-out adjustable pillow core to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pull-out adjustable pillow core, which solves the problem that existing airbag adjustable pillows have complex structures and require cumbersome and inconvenient operation when adjusting the pillow core height during sleep.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pull-out adjustable pillow core, comprising a pillow core and a pillowcase, wherein the pillowcase wraps around the outside of the pillow core, and the pillow core includes an upper inner core and a lower inner core, wherein the upper inner core is positioned above the lower inner core, and a middle inner core is provided between the upper and lower inner cores, wherein a first elastic fabric is connected to the front side of the upper inner core, and a second elastic fabric is connected to both sides of the upper inner core, wherein a first through groove is provided in the middle of the first elastic fabric, and a pull strip is installed on the side of the middle inner core facing the first elastic fabric.

[0008] Preferably, the end of the middle inner liner facing the first elastic fabric is smaller than the other end, and the middle inner liner is frustoconical in shape.

[0009] Preferably, the pull strip passes through the first through groove, and the front side of the pillowcase has a second through groove. The pull strip passes through the second through groove. When adjusting the height of the pillow core, the pull strip passing through the first and second through grooves can be pulled towards the side of the middle inner core closer to the first through groove, so that the middle inner core enters the depth of the upper and lower inner cores. This changes the distance between the upper and lower inner cores according to the state of the cone-shaped platform of the middle inner core, thereby achieving the effect of changing the height of the pillow core.

[0010] Preferably, the front side of the upper inner liner is connected to the front side of the lower inner liner via a first elastic fabric, and the side of the upper inner liner is connected to the side of the lower inner liner via a second elastic fabric, wherein the first elastic fabric and the second elastic fabric are made of elastic fiber fabric.

[0011] (III) Beneficial Effects
