Specific embodiment 1

[0037] The cotton fiber layer 1 is made of ordinary cotton fiber and water-repellent cotton fiber mixed and combed according to (20-30): (70-80), with a gram weight of 80-150g / m 2 Among them, the length of ordinary cotton fiber is about 28-34mm, and the length of water-repellent cotton fiber is about 25-29mm. This ratio is obtained through optimization and screening of water washing tests. Under this ratio, it can ensure water washing resistance and the highest cost performance.

[0038] The fluffy fiber layer 2 is made of 5D / 7D / 15D three-dimensional curly spiral fibers and low melting point fibers mixed and combed in the ratio of (80-90): (10-20), with a gram weight of 200-500g / m 2The length of the three-dimensional coiled helical fiber is about 51 to 64 mm.

[0039] In this embodiment, the cotton layer of the mattress can be directly put into the washing machine for washing, and can be washed about 20 times. It is not easy to clump after washing, which effectively increases the number of washing times. At the same time, the overall mattress has good fluffiness and support, a smooth appearance, and good dimensional stability. As the mixing ratio of water-repellent cotton fibers increases, the number of washable times increases, and the ability to resist moisture absorption increases. It is allowed that the cotton fiber layer 1 is entirely made of water-repellent cotton fibers. As the specifications of the three-dimensional curled spiral fibers increase or the mixing ratio increases, the support capacity of the mattress increases, and it is allowed that the fluffy fiber layer 2 is entirely made of three-dimensional curled spiral fibers.

[0040] The quilting pattern of the outer area of ​​the upper cushion cover 7 and the cotton fiber layer 1 is a lantern-shaped lattice. The lantern-shaped lattice is in a quadrilateral shape, and the four corners of the quadrilateral are in an arc shape with the opening facing outward. At least four lantern-shaped lattices are symmetrically arranged on the left and right sides of the upper cushion cover 7 and the cotton fiber layer 1, and the lantern-shaped lattices on the same side are arranged side by side. The size of the lantern-shaped lattice here does not exceed 30*30cm, so as to avoid the problem of cotton batting clumping and breaking caused by the large centrifugal force in the outer area during machine washing. The top and foot of the upper cushion cover 7 and the cotton fiber layer 1 are symmetrically provided with four lantern-shaped lattices, of which three lantern-shaped lattices 3 with smaller areas are located in a lantern-shaped lattice with a larger area. The lantern-shaped lattice is thus used to limit the position of the cotton fiber, so that it is not easy to clump or break after washing.

[0041] The upper area of ​​the upper cushion cover 7 and the cotton fiber layer 1 is quilted in an arc-shaped grid 4. The arc-shaped grid 4 is formed by connecting the first arc located at the top and opening upward, the second arc located at the right side and opening leftward, the third arc located at the lower right side and opening upward, the fourth arc located at the lower left side and opening upward, and the fifth arc located at the left side and opening rightward in sequence. When the mattress is in use, this area corresponds to the shoulders and back of the human body.

[0042] The quilting pattern of the middle area of ​​the upper cushion cover 7 and the cotton fiber layer 1 is a small ring 5. The even number of small rings is divided into two groups, which are arranged side by side on the left and right. When the mattress is in use, this area corresponds to the waist of the human body.

[0043] The quilting pattern of the upper cushion cover 7 and the lower area of ​​the cotton fiber layer 1 is a large circle 6. The large circles are arranged side by side. When the mattress is in use, this area corresponds to the buttocks and the lower area of ​​the human body. The radius of the large circle is greater than the radius of the small circle. The diameter of the large circle is about 50 cm. The diameter of the small circle is about 30 cm.

[0044] The quilting pattern of the upper area of ​​the lower cushion cover 10 and the fluffy fiber layer 2 is a large four-pointed star 8. The large four-pointed stars are arranged side by side. When the mattress is in use, this area corresponds to the shoulders and back of the human body. The large four-pointed star on the lower layer corresponds to the position of the top lantern-shaped grid on the upper layer.

[0045] The quilting pattern of the middle area of ​​the lower cushion cover 10 and the fluffy fiber layer 2 is a small four-pointed star 9. An even number of small four-pointed stars are divided into two groups, which are arranged side by side on the left and right. When the mattress is in use, this area corresponds to the waist of the human body. The area of ​​the large four-pointed star is larger than the area of ​​the small four-pointed star. The upper group of the small four-pointed stars on the lower layer corresponds to the position of the arc grid on the upper layer, and the lower group of the small four-pointed stars on the lower layer corresponds to the position of the upper group of small circular rings on the upper layer.

[0046] The quilting pattern of the lower area of ​​the lower cushion cover 10 and the fluffy fiber layer 2 is two symmetrically arranged quadrilaterals. The corners of the quadrilateral located on the outer side of the upper part are arc-shaped, and the corners of the quadrilateral located on the inner side of the lower part are arc-shaped. When the mattress is in use, this area corresponds to the buttocks and the area below the human body. The quadrilateral on the lower layer corresponds to the position of the large circular ring on the upper layer. Preferably, the large circular ring is located inside the quadrilateral.

[0047] This embodiment optimizes the quilting pattern. Through the zoned quilting process, the size of the mattress surface pattern is zoned according to the needs of ergonomics. The quilting size of the shoulder and back should be larger, the quilting size of the waist should be smaller, and the quilting size of the buttocks and below should be larger, so that the shoulder and back area is softer, the waist is harder, and the buttocks and below are softer, so that the human body can better fit the natural physiological curve. In addition, the patterns of the upper and lower layers are relative but different, and the difference in patterns is used to limit each other, thereby improving the problem of misalignment and wrinkling between the upper and lower layers.

[0048] An elastic sheet such as a spring or a spring sheet can be embedded in the lower sleeve, and the elastic sheet is preferably made of metal. A magnet can be embedded in the upper sleeve. Thus, the upper sleeve and the lower sleeve are more stably connected together by magnetic attraction. The magnet is preferably embedded in the small circular ring 5. Thus, the small circular ring is used to limit the magnet, so that the middle part of the upper sleeve and the middle part of the lower sleeve are better aligned.

[0049] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
