Abstract
Description
Technical Field
[0001] This utility model relates to the field of household goods technology, and more specifically, to a multifunctional two-way temperature-controlled quilt. Background Technology
[0002] A quilt is a type of bedding, a rectangular piece of fabric large enough to cover the body, generally used for warmth during sleep. A quilt typically consists of a duvet cover or sheet wrapped around cotton batting; quilts made of cotton are called cotton quilts. Besides cotton, quilts can also be made of wool, silk, or synthetic fibers such as acrylic fibers.
[0003] However, existing household quilts have limited functionality and can only be used as a single item. For example, existing quilts can only be used to cover the body and cannot be used as sleeping bags. Moreover, existing quilts do not have temperature regulation capabilities, causing the user to feel hot one moment and cold the next. Therefore, we have proposed a multi-functional two-way temperature-controlled quilt to solve the above-mentioned problems. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multifunctional two-way temperature control quilt.

[0018] 3. Beneficial effects
[0019] Compared with existing technologies, the advantages of this utility model are:
[0020] (1) This solution can be used as a quilt by laying the quilt cover and the quilt core flat, and can be used as a sleeping bag by folding the quilt cover and the quilt core in half and then pulling the zipper head to make the first zipper and the second zipper engage together.
[0021] (2) In this design, the quilt cover is designed with a double-line three-dimensional edging design through the first and second seams. Compared with the single line, the double line can double the filling space, lock in more air to form a heat insulation layer. The PCM material in the temperature-controlled quilt core is wrapped inside the fiber and then made into a temperature-controlled wadding. When a person sweats in the quilt and the surrounding temperature is too high, the PCM phase change material in the temperature-controlled wadding will absorb heat and change from solid to liquid, thereby reducing the temperature inside the quilt. When the temperature of the quilt is too low, the PCM phase change material changes from liquid to solid and releases heat to increase the temperature of the quilt, thus achieving bidirectional temperature control.
[0022] (3) This solution allows the eye mask to be detached from the female buckle and stored in a storage bag, making it convenient for users to take out and use the eye mask, and has a storage function. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0031] Example:
[0032] Please see Figure 1-5 A multifunctional bidirectional temperature-controlled quilt includes a quilt cover 1 and a quilt core 2 filled inside the quilt cover 1. The bottom and top edges of the quilt cover 1 are respectively sewn with a first seam 3 and a second seam 4, and the first seam 3 and the second seam 4 form a double-line three-dimensional edge binding structure of the quilt cover 1.
[0033] The two sides of the quilt cover 1 are sewn together with a first zipper 5 and a second zipper 6 respectively. Both the first zipper 5 and the second zipper 6 are L-shaped and symmetrically arranged. The root of the first zipper 5 and the second zipper 6 are connected with zipper heads 7.
[0034] A storage bag 8 is sewn onto the surface of the quilt cover 1. A male buckle 9 is installed at the opening of the storage bag 8, and a female buckle 10 is installed on the quilt cover 1 at the corresponding position of the male buckle 9.
[0035] It should be noted that when using this multi-functional two-way temperature-controlled quilt, it can be used as a quilt by laying the quilt cover 1 and the quilt core 2 flat, or it can be used as a sleeping bag by folding the quilt cover 1 and the quilt core 2 in half and then pulling the zipper head 7 to make the first zipper 5 and the second zipper 6 engage together.
[0036] The duvet cover 1 is made of pure cotton, and the duvet core 2 is filled with PCM phase change temperature-regulating fiber. The duvet cover 1 is designed with a double-line three-dimensional edging design through the first seam 3 and the second seam 4. This double-line design can double the filling space compared to the single-line design, locking in more air to form a heat insulation layer. The PCM material in the temperature-regulating duvet core 2 is wrapped inside the fiber and then made into a temperature-regulating wadding. When a person sweats inside the duvet and the surrounding temperature is too high, the PCM phase change material in the temperature-regulating wadding will absorb heat and change from solid to liquid, thereby lowering the temperature inside the duvet. When the temperature inside the duvet is too low, the PCM phase change material changes from liquid to solid, releasing heat to raise the temperature inside the duvet.
[0037] The eye mask is detached from the male buckle 9 and the female buckle 10, and stored in the storage bag 8 for easy access and use by the user.
[0038] like Figure 1 As shown, a first binding is sewn onto the first suture 3, and the first binding is filled with temperature-regulating fibers; a second binding is sewn onto the second suture 4, and the second binding is filled with heat-storing fibers.
[0039] It should be noted that the double-line three-dimensional edging compensates for the filling space lost by the single-line edging of the comforter core 2. This design forms an air insulation layer that is twice as thick as that of the single-line edging of the comforter core 2, which can slow down heat loss and prevent cold air from entering, making the user sleep warmer and more comfortably.
[0040] like Figure 5 As shown, an eye mask is placed inside the storage bag 8;
[0041] It should be noted that the eye mask is stored in the storage bag 8, making it convenient for users to take out and use the eye mask.
[0042] like Figure 1 As shown, the surface of the liner 1 is processed by a bubble pressing process to form a bubble pressing grid 11, and multiple bubble pressing grids 11 are arranged in an array.
[0043] It should be noted that this was achieved by performing a TACTILE IMPRESSION on surface 1. TM The foam pressing process creates a layer of foam grids on the surface, making the quilt fit the body better, be more skin-friendly and warmer, like a sleeping bag, gently wrapping the whole body to maintain temperature.
[0044] like Figure 1 As shown, the corners of the quilt cover 1 are sewn together with corner stitches 12 for securing the quilt core 2.
[0045] It should be noted that locking the comforter core 2 prevents it from moving around, thus improving the overall comfort of the comforter.
[0046] When in use: By laying the quilt cover 1 and the quilt core 2 flat, it can be used as a quilt. By folding the quilt cover 1 and the quilt core 2 in half and then pulling the zipper head 7 to make the first zipper 5 and the second zipper 6 engage together, the quilt can be used as a sleeping bag.
[0047] The duvet cover 1 is made of pure cotton, and the duvet core 2 is filled with PCM phase change temperature-regulating fiber. The duvet cover 1 is designed with a double-line three-dimensional edging design through the first seam 3 and the second seam 4. This double-line design can double the filling space compared to the single-line design, locking in more air to form a heat insulation layer. The PCM material in the temperature-regulating duvet core 2 is wrapped inside the fiber and then made into a temperature-regulating wadding. When a person sweats inside the duvet and the surrounding temperature is too high, the PCM phase change material in the temperature-regulating wadding will absorb heat and change from solid to liquid, thereby lowering the temperature inside the duvet. When the temperature inside the duvet is too low, the PCM phase change material changes from liquid to solid, releasing heat to raise the temperature inside the duvet.
[0048] The eye mask is detached from the male buckle 9 and the female buckle 10, and stored in the storage bag 8 for easy access and use by the user.
[0049] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
