Technical Field
[0001] This utility model relates to the field of bedding technology, and in particular to a detachable multifunctional comforter set. Background Technology
[0002] Traditional duvet covers suffer from drawbacks such as inconvenience in washing, poor retention of the duvet insert, and compromised warmth retention. To address these issues, detachable, multi-functional duvet insert sets have emerged. These sets feature a detachable design, allowing for easy separation and combination of the duvet insert and cover, facilitating washing and replacement. Furthermore, their multi-functional design meets users' diverse needs for duvets in different seasons and occasions.
[0003] A multifunctional duvet cover disclosed in publication number CN215604696U consists of a left duvet cover and a right duvet cover. Each duvet cover has an opening on one side, with a zipper attached to the opening. The two rows of zipper teeth on the zipper sides of the left and right duvet covers are arranged in an alternating pattern. This invention uses reversed zipper teeth on the left and right duvet covers, allowing the duvet covers to be combined both horizontally and vertically. Individual and combined use do not affect each other, and operation is convenient.
[0004] While the aforementioned patent achieves the goal of sewing the left and right duvet covers together with opposite zipper teeth, allowing the duvet covers to be combined both left and right, and top and bottom, with no interference between individual and combined use, and is convenient to operate, the duvet cover is sewn together on three sides. When putting on the duvet insert, the inside is not clearly visible, and when using ties to fix the duvet cover and duvet insert together, it takes a lot of time and effort to tie and untie, increasing the complexity of daily use. Furthermore, when the left and right duvet covers are used together, washing or replacing them requires the whole duvet cover to be done, and local washing is not possible to meet daily cleaning needs.

[0015] (III) Beneficial Effects
[0016] This utility model provides a detachable multifunctional comforter set, which has the following advantages:
[0017] 1. This detachable multi-functional duvet cover set features an upper duvet cover, a lower duvet cover, a tie-on mechanism, and an opening and closing mechanism. When changing the duvet cover, first pull the two sets of zipper pulls in opposite directions, then lay the lower duvet cover flat on the bed. After peeling off the Velcro straps of the horizontal and vertical ties, set the ties aside. Next, lay the duvet cover flat on the lower duvet cover, then glue the loop and hook sides of the horizontal and vertical ties together. Finally, connect the upper and lower duvet covers together using the two sets of zipper pulls. This simplifies the duvet cover changing process. Users only need to open the zippers on three sides to easily insert the duvet cover, then zip it up to complete the change, greatly improving efficiency. The ties easily secure the duvet cover, avoiding the tediousness of tying it in place, making duvet cover changing easy and simple.
[0018] 2. This detachable multi-functional comforter set, through the design of the snap fastener and detachable mechanism, allows for flexible connection and separation between the comforter set and the undercover. When the sweat-absorbing layer is needed, the protruding part of the snap fastener can be engaged with the groove of the female snap fastener, connecting the sweat-absorbing layer to the undercover. This achieves the multi-functional and detachable characteristics of the undercover and the sweat-absorbing layer. Several raised massage particles on the surface of the sweat-absorbing layer provide a gentle massage to the body, promoting blood circulation and relieving fatigue. The sweat-absorbing layer can be installed or removed as needed, and only the sweat-absorbing layer can be washed when required, reducing the frequency of comforter cover replacement, saving time and effort. Furthermore, the use of the sweat-absorbing layer provides better comfort and health benefits during comforter use. Attached Figure Description
