[0036] The comfortable inflatable mattress provided in the above embodiment is provided with a comfortable layer group 1, and the comfortable layer group 1 includes multiple buffer layers arranged in sequence from top to bottom. When the human body contacts the comfortable layer group 1, the comfortable layer group 1 can give the user a softer and more comfortable use experience. In addition, since the welding layer 2 can bond the two adjacent buffer layers, or the welding layer 2 is arranged between the bottom buffer layer and the inflatable layer group 3, the welding layer 2 is sewn with each buffer layer, so that the layers of the comfortable inflatable mattress are better connected, the surface layer is not easy to move during use, and the problem of obvious bumps and bumps after inflation is alleviated.

[0037] According to different configurations of the welding layer 2, the comfortable air mattress can be divided into the following two embodiments:

[0038] Embodiment 1

[0039] In this embodiment 1, if Figure 1 and Figure 2 As shown, the multi-layer buffer layer includes a first original fabric layer 11, a first cotton layer 12 and a non-woven fabric layer 13 arranged in sequence from top to bottom. The first original fabric layer 11 is the top surface of the comfortable inflatable mattress, that is, the surface that directly supports the human body.

[0040] The above-mentioned comfort layer group 1 has a first cotton layer 12, which can make the texture softer after being inflated, thereby improving the comfort of use.

[0041] The first original fabric layer 11 may be made of pile knitted fabric, the thickness of which is 50d and the weight is 36g per square meter.

[0042] Of course, the first original fabric layer 11 can also be replaced by various woven fabrics, knitted fabrics or non-woven fabrics without scraping glue.

[0043] The first cotton layer 12 may be made of domestically produced cotton with a weight of 80 g per square meter, which increases air permeability and softness.

[0044] Of course, domestic cotton can also be replaced by various filling materials of different grams, such as pearl cotton, down, etc.

[0045] The weight of the non-woven fabric layer 13 can be selected according to specific needs.

[0047] The first welding film 21, the first original fabric layer 11, the first cotton layer 12 and the non-woven fabric layer 13 are sewn together to make the comfort layer group 1 fit the airbed better, with a better overall shape. The surface of the comfort layer group 1 is less likely to move during use, and the bumpy feeling is not obvious after inflation, thereby enhancing the sense of home and refinement.

[0048] In the first embodiment, the first welding film 21 is made of the existing TPU film.

[0049] Preferably, the thickness of the first welding film 21 is 5.5 filaments, so that the comfort layer group 1 and the inflation layer group 3 are bonded to each other without adding too much weight, and at the same time, the top layer of the inflation layer group 3 is reinforced.

[0050] It can be understood that 1 wire is equal to 0.01 mm.

[0051] Of course, the thickness of the first welding film 21 is not limited to 5.5 filaments, and other suitable filament counts may also be used.

[0052] In addition, TPU film can be replaced by other materials with hot melt adhesive properties such as hot melt adhesive, PVC, etc.

[0053] In this embodiment 1, optionally, as Figure 3 and Figure 4As shown, when there is a heat pressing line 4 extending in a straight line between the welding layer 2 and the comfort layer group 1, the seam line 5 where the welding layer 2 and the comfort layer group 1 are sewn together is arranged according to the hot pressing mold line. Specifically, the seam line 5 coincides with the hot pressing line 4, or the seam line 5 is parallel to the hot pressing line 4 and the distance is less than the first dimension, and the first original fabric layer 11, the first cotton layer 12, the non-woven fabric layer 13 and the first welding film 21 are fixed together according to the direction of the line.

For example, the stitching line 5 is parallel to the hot pressing line 4 and the distance between the two can be 0.1 mm, 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 4 mm or 5 mm.

[0055] The stitching line 5 may be a quilting line or an ultrasonic line.

[0056] In this embodiment 1, optionally, as Figure 5 and Figure 6 As shown, when there is an annular hot pressing line 4 between the welding layer 2 and the comfort layer group 1, the seam line 5 where the welding layer 2 and the comfort layer group 1 are sewn together is arranged according to the hot pressing mold line. Specifically, the seam line 5 coincides with the hot pressing line 4, or the seam line 5 is surrounded by the outside of the hot pressing line 4, and the distance between the seam line 5 and the hot pressing line 4 is less than the second size, and the first original fabric layer 11, the first cotton layer 12, the non-woven fabric layer 13 and the first welding film 21 are fixed together according to the direction of the line.

[0057] See also Figure 6 The shape of the seam line 5 is similar to that of the hot pressing line 4 , and an annular gap is formed between the seam line 5 and the hot pressing line 4 , and the width of the annular gap is less than 3 mm, that is, the second size can be 3 mm.

[0058] Specifically, the width of the annular gap may be 0.1 mm, 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm or 2.5 mm.

[0059] Of course, the width of the annular gap is not limited to being smaller than the second size mentioned above, and the second size can be adjusted according to actual needs.

[0060] The stitching line 5 may be a quilting line or an ultrasonic line.

[0061] Of course, in other embodiments, quilting lines or ultrasonic lines may also be arranged according to other types of hot pressing die lines.

[0062] In other embodiments, quilting lines or ultrasonic lines may not be arranged according to the direction of the hot pressing mold lines or points, and a mesh or various regular patterns may be used for quilting or ultrasonic waves to fix the first original fabric layer 11, the first cotton layer 12, the non-woven fabric layer 13 and the first welding film 21 together according to the direction of the lines.

[0063] In this embodiment 1, if Figure 1 and Figure 2 As shown, the inflation layer group 3 includes a second welding film 31 , a first lacing rod 32 and a first base fabric 33 arranged in sequence from top to bottom.

[0067] Of course, the materials of the first tensioning rod 32 and the first base fabric 33 can also be various types of nylon, polyester pongee, stretch fabric, suede and the like.

[0068] The comfortable inflatable mattress provided in the above-mentioned embodiment 1 first sews the comfort layer group 1 consisting of the first original fabric layer 11, the first cotton layer 12 and the non-woven fabric layer 13 together with the first welding film 21 through a quilting process, and then connects it with the second welding film 31, the first tensioning rod 32 and the first base fabric 33 by hot pressing according to the set welding line, and keeps a distance from the edge of the airbed to ensure air circulation.

[0069] The overall weight of the comfortable inflatable mattress provided in the above-mentioned embodiment 1 has only a small increase. Compared with a sponge bed, it is smaller in size, lighter in weight, and more convenient to carry; compared with an inflatable bed with a traditional scraped rubber fabric, it is more comfortable, breathable, and quieter; compared with an inflatable bed with a cloth cover, the original cloth layer fits the air bed better and is not easy to move, while having a more integrated shape.

[0073] The second original fabric layer 14 can be made of pile knitted fabric, the thickness of which is 50d and the weight is 36g per square meter.

[0074] Of course, the second original fabric layer 14 can also be replaced by various woven fabrics or knitted fabrics without scraping glue.

[0075] The second cotton layer 15 can be made of domestic cotton with a weight of 80 g per square meter to increase air permeability.
