Description

Technical Field

[0001] This utility model mainly relates to the field of pillow technology, specifically to a combined down pillow. Background Technology

[0002] A pillow is a sleep aid, a common bedding item used when sleeping or resting. Generally, pillows are considered a filling material used for sleep comfort. Modern medical research shows that the human spine, viewed from the front, is a straight line, but viewed from the side, it has four physiological curves. To protect the normal physiological curvature of the neck and maintain normal physiological activity during sleep, a pillow is necessary.

[0003] There are many types of pillows and their filling materials, with down pillows being a common choice for winter. However, traditional down pillows typically have a one-piece filling structure, usually used in winter and replaced with other pillows in the hot spring, autumn, or summer. This not only increases the purchase cost for consumers but also requires more space to store different pillows. Furthermore, the one-piece down filling of traditional down pillows results in insufficient support, potentially creating blind spots in the cervical spine area. Therefore, it is necessary to propose an improvement measure to solve these technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a modular down pillow to solve the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a combined down pillow, comprising an inner pillow core and a down pillowcase, wherein a detachable cassia seed pillow pad is installed on the inner side of the inner pillow core, and a rectangular groove is provided in the middle of the bottom side of the inner pillow core; the down pillowcase has a ring structure, and the down pillowcase is fitted onto the outer side of the inner pillow core, and the down filling thickness at the top of the down pillowcase is greater than the down filling thickness at the bottom of the down pillowcase.

[0009] Furthermore, the inner pillow core is provided with pillow pad mounting holes with openings on both sides, and the cassia seed pillow pad is installed in the pillow pad mounting holes; two elastic bands are provided on both sides of the cassia seed pillow pad, and the ends of the elastic bands are provided with connectors. The elastic bands on both sides of the cassia seed pillow pad are fastened to the bottom of the inner pillow core and connected by the connectors.

[0010] Furthermore, the connector includes buckles and buckle holes. Multiple buckles are installed on the end of the elastic band on one side of the cassia seed pillow, and multiple buckle holes are provided on the end of the elastic band on the other side of the cassia seed pillow. The buckles on the elastic band on one side of the cassia seed pillow are fastened into the buckle holes on the elastic band on the other side of the cassia seed pillow.

[0011] Furthermore, the connector is a snap fastener. Multiple female snap fasteners are installed on the end of the elastic band on one side of the cassia seed pillow, and multiple male snap fasteners are installed on the end of the elastic band on the other side of the cassia seed pillow. The female snap fasteners on the elastic band on one side of the cassia seed pillow and the male snap fasteners on the elastic band on the other side of the cassia seed pillow are fastened together.

[0012] Furthermore, the down pillowcase has an opening design on both sides, and a corresponding pillow core cavity is provided inside for accommodating the inner pillow core. The inner pillow core is installed inside the pillow core cavity of the down pillowcase, and opening and closing components are also provided at the openings on both sides of the down pillowcase.

[0013] Furthermore, the opening and closing parts on both sides of the down pillowcase are zippers.

[0014] Furthermore, the size of the cassia seed pillow pad is adapted to the size of the pillow pad mounting hole, and the size of the inner pillow core is adapted to the size of the pillow core cavity on the down pillowcase.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This utility model features a reasonable design. By replacing the traditional one-piece pillow with a combined structure of a cassia seed pillowcase, an inner pillow core, and a down pillowcase, the down pillowcase can be worn over the inner pillow core in winter. In spring, autumn, or summer, the down pillowcase can be removed. This reduces costs for consumers by requiring only one pillow and eliminates the need for multiple pillows. Furthermore, the design of the inner pillow core with a down pillowcase significantly improves the pillow's support compared to a one-piece down-filled pillow. The rectangular groove design in the center of the bottom side makes the middle of the pillow slightly concave downwards and the sides slightly convex upwards, so as to better support the neck when using it; the cassia seed pillow pad inside the pillow core can further improve the user's sleep effect and promote better sleep; the elastic bands on both sides of the cassia seed pillow pad make it easy to pull the cassia seed pillow pad from the side of the pillow pad installation hole of the inner pillow core during installation and removal, which facilitates quick installation and removal of the cassia seed pillow pad. After installation, the cassia seed pillow pad can also be fixed by the elastic bands. Its overall design is ingenious, flexible and convenient to use, and highly practical.

[0018] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0030] See attached document Figure 1-5 This embodiment of a combined down pillow includes an inner pillow core 1 and a down pillowcase 2. A removable cassia seed pillow pad 3 is installed on the inner side of the inner pillow core 1, and a rectangular groove 102 is provided in the middle of the bottom side of the inner pillow core 1. The down pillowcase 2 has a ring structure and is fitted onto the outer side of the inner pillow core 1. The down filling thickness at the top of the down pillowcase 2 is greater than the down filling thickness at the bottom of the down pillowcase 2.

[0031] Specifically, the inner pillow core 1 has pillow pad mounting holes 101 with openings on both sides. The size of the cassia seed pillow pad 3 is adapted to the size of the pillow pad mounting holes 101, and the cassia seed pillow pad 3 is installed in the pillow pad mounting holes 101. Two elastic bands 4 are provided on each side of the cassia seed pillow pad 3, and the ends of the elastic bands 4 are provided with connectors. The elastic bands 4 on both sides of the cassia seed pillow pad 3 are fastened to the bottom of the inner pillow core 1 and connected by the connectors.

[0032] There are several options for the connecting component. For example, the connecting component includes buttons and snap holes. Multiple buttons 5 are installed on the end of the elastic band 4 on one side of the cassia seed pillow cushion 3, and multiple snap holes are provided on the end of the elastic band 4 on the other side of the cassia seed pillow cushion 3.
