Description

Technical Field

[0001] This utility model relates to the field of bedding technology, specifically to a duvet cover with selective localized warmth retention. Background Technology

[0002] Bedding refers to items placed on a bed for people to use while sleeping, including quilts, duvet covers, sheets, bedspreads, fitted sheets, pillowcases, pillow inserts, blankets, mats, and mosquito nets. Duvet covers (commonly known as "quilt covers") are a type of bedding product. They are used to cover the cotton quilt insert to prevent it from getting dirty and are easy to wash themselves.

[0003] To meet the changing needs of different seasons, people usually prepare quilts of varying thicknesses for use in different seasons. Changing quilts of different thicknesses with the seasons is not only inconvenient but also requires additional storage of the used quilts, increasing living costs to some extent. Therefore, various types of quilt sets with detachable inner and outer covers have appeared on the market. These are detachable inner and outer covers that can be attached to the outside of the inner cover to meet the needs of different seasons. Most existing quilt sets have inner and outer covers that are the same size, differing only in thickness. Typically, only the inner cover is used in spring and autumn, only the outer cover in summer, and in winter, the inner and outer covers can be stacked together to form a thicker quilt. Such a double-layer quilt improves the utilization rate of a single quilt to a certain extent and saves quilt storage space, but there are the following technical problems: (1) The connecting parts (such as buttons, zippers, Velcro, etc.) used to connect the double-layer quilt and the mother quilt are mostly set at the outer periphery of the two. When people use the quilt, they usually fold the two sides and the outer edge of the foot of the quilt back from top to bottom into the quilt to ensure that the inside of the quilt has a good heat retention effect (especially in winter). At this time, the connecting parts used to connect the double-layer quilt and the mother quilt are folded into the quilt and in contact with the human body. Moreover, the hardness of the connecting parts is generally large, which causes the human body to feel the contact with foreign objects and poor sleep comfort. (2) In real life, we often encounter such problems. The body temperature of husband and wife is different. Under the same ambient temperature, the need for the thickness of the quilt is also different. Using the same thickness of quilt, one party may feel comfortable, while the other party feels too cold or too hot. However, the double-layer quilt and the mother quilt of the existing double-layer quilt are the same size. The mother quilt can only be used at the same time or the double-layer quilt can be added at the same time, which is difficult to meet the needs of both husband and wife. Furthermore, most commercially available duvet covers are designed with a separate duvet insert. Adding or removing the inner duvet requires removing the outer cover, and after removing the inner duvet from the outer duvet or attaching it to the outer duvet, the outer cover must be put back on the duvet insert. This cumbersome process significantly impacts the user experience. Therefore, this invention proposes a duvet cover with a selective localized warmth function to address the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a duvet cover with a local selective warmth function. By detachably installing a covering on the left and / or right sides of the duvet cover, the thickness of the left and / or right sides of the duvet can be adjusted according to the different body temperatures felt by both users, so that both users feel a comfortable temperature. The outer periphery of the covering is recessed inside the corresponding outer periphery of the duvet cover. When the outer edge of the duvet cover is folded back from top to bottom inside the duvet cover to improve the warmth effect, the outer periphery of the covering is located outside the duvet, effectively avoiding the feeling of contact with foreign objects and improving sleep comfort. When the covering needs to be added or removed due to seasonal changes, the covering can be removed directly without removing the duvet cover, making the operation simple and providing a good user experience.

[0005] One of the objectives of this utility model is to design a duvet cover with a local selective heat preservation function, comprising a duvet cover, wherein a covering is detachably and fixedly installed on the left and / or right sides of the upper side of the duvet cover, and the outer periphery of the covering is recessed into the inner side of the corresponding outer periphery of the duvet cover.

[0006] This utility model discloses a duvet cover with a selective localized warmth function. By detachably installing a covering on the left and / or right sides of the duvet cover, the thickness of the left and / or right sides of the duvet can be adjusted according to the different perceived temperatures of both users, thus ensuring a comfortable temperature for both. The outer periphery of the covering is recessed inside the corresponding outer periphery of the duvet cover. When the outer edge of the duvet cover is folded back from top to bottom inside the duvet to improve warmth, the outer periphery of the covering is always outside the duvet, effectively preventing the body from feeling any foreign object and ensuring good sleep comfort. When the season changes and the covering needs to be added or removed, it can be simply removed without removing the duvet cover, making it simple to operate and providing a good user experience.

[0007] A preferred technical solution is that the distance between the left and right edges of the covering and the left and right edges of the duvet cover is set as d1, the distance between the front edge of the covering and the front edge of the duvet cover is set as d2, and the distance between the rear edge of the covering and the rear edge of the duvet cover is set as d3. The values ​​of d1, d2, and d3 are all within the range of 10–90 cm. The reasonable design of the distance between the outer perimeter of the covering and the corresponding outer perimeter of the duvet cover ensures that the covering can cover the entire torso of the user on the corresponding side, providing sufficient warmth. Furthermore, it ensures that the outer edge of the duvet cover can be folded back from top to bottom inside the duvet, and that the outer perimeter of the covering is located outside the duvet cover, thus preventing any feeling of contact with foreign objects and improving sleep comfort.

[0008] A further preferred technical solution is that a detachable connector is provided between the outer periphery of the covering and the upper side of the duvet cover to detachably connect the two. This ensures the ease of attaching and detaching the covering from the duvet cover.

[0009] A further preferred technical solution is that the covering material is one of a blanket, a quilt, or a quilt with a quilt cover. When the covering material is a quilt with a quilt cover, a detachable connector is provided between the outer periphery of the quilt cover and the upper side of the quilt cover to detachably connect the two together. The variety of covering materials available allows for greater flexibility in adjusting the thickness of the quilt to different areas. Since the covering material is a quilt with a quilt cover, the quilt cover can be removed and washed together with the quilt cover, improving storage convenience.

[0010] A further preferred technical solution is that the detachable connector is one of a button assembly, a zipper assembly, or a Velcro assembly. The covering is installed on the duvet cover using a detachable connection method commonly used in knitwear, ensuring the ease of installation and removal of the covering. This also allows both the duvet cover and the covering to be washed and stored separately after the covering is removed.

[0011] The second objective of this utility model is to design a duvet cover with a local selective heat preservation function, including a duvet cover, wherein a covering is detachably and fixedly installed on the upper and / or lower sides of the upper side of the duvet cover, and the outer periphery of the covering is recessed into the inner side of the corresponding outer periphery of the duvet cover.

[0012] This utility model discloses a duvet cover with localized selective warmth function. By detachably installing a covering on the upper and / or lower side of the duvet cover, the thickness can be adjusted according to the user's specific warmth needs in different areas, such as the feet or shoulders, to prevent overall stuffiness. The outer periphery of the covering is recessed inside the corresponding outer periphery of the duvet cover. When the outer edge of the duvet cover is folded back from top to bottom inside the duvet cover to improve warmth, the outer periphery of the covering is always outside the duvet, effectively preventing the body from feeling any foreign object contact and ensuring good sleep comfort. When the season changes and the covering needs to be added or removed, it can be simply removed without removing the duvet cover, making it simple to operate and providing a good user experience.

[0013] Preferably, the distance between the left and right edges of the covering and the left and right edges of the duvet cover is set as D1, the distance between the front edge of the covering and the front edge of the duvet cover is set as D2, and the distance between the rear edge of the covering and the rear edge of the duvet cover is set as D3. The values ​​of D1, D2, and D3 are all within the range of 10–90 cm. The reasonable design of the distance between the outer perimeter of the covering and the corresponding outer perimeter of the duvet cover ensures that the covering can fully cover the areas requiring warmth, providing adequate localized warmth. Furthermore, it ensures that the outer edge of the duvet cover, which is fitted with the duvet cover, can be folded back from top to bottom inside the duvet, and that the outer perimeter of the covering is located outside the duvet cover, thus preventing any feeling of contact with foreign objects and improving sleep comfort.

[0014] A further preferred technical solution is that a detachable connector is provided between the outer periphery of the covering and the upper side of the duvet cover to detachably connect the two. This ensures the ease of attaching and detaching the covering from the duvet cover.

[0015] A further preferred technical solution is that the covering material is one of a blanket, a quilt, or a quilt with a quilt cover. When the covering material is a quilt with a quilt cover, a detachable connector is provided between the outer periphery of the quilt cover and the upper side of the quilt cover to detachably connect the two together. The variety of covering materials available allows for greater flexibility in adjusting the thickness of the quilt to different areas. Since the covering material is a quilt with a quilt cover, the quilt cover can be removed and washed together with the quilt cover, improving storage convenience.

[0016] A further preferred technical solution is that the detachable connector is one of a button assembly, a zipper assembly, or a Velcro assembly. The covering is installed on the duvet cover using a detachable connection method commonly used in knitwear, ensuring the ease of installation and removal of the covering. This also allows both the duvet cover and the covering to be washed and stored separately after the covering is removed.
