Description:
CROSS-REFERENCE TO PRIORITY CLAIM 
     This application claims priority under 35 U.S.C. § 119 to Chinese Application No. 202111370219.7 filed Nov. 18, 2021. The contents of the aforementioned application are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to the technical field of inflatable cushions, and particularly to an inflatable cushion. 
     BACKGROUND 
     Because of small volume, light weight and convenience in carrying, the inflatable cushion is often used for camping or encamping. Because the interior of the existing inflatable cushion is filled with gas, the inflatable cushion is soft, but low in comfort. The interior of the existing another inflatable cushion is fully filled with sponge, and is large in volume, heavy in weight and inconvenient in carrying and storage.

     DETAILED DESCRIPTION 
     A technical problem to be solved by the present invention is to provide an inflatable cushion with convenience in carrying, high comfort and folding storage with respect to the problems of the prior art. 
     The present invention is further described below in detail in combination with the drawings and embodiments. 
     Embodiment 1 
     As shown in  FIG.  1    to  FIG.  2   , an inflatable cushion comprises an inflatable cushion body. The inflatable cushion body comprises a first region  1  and a second region  2  formed by pressing an upper and a lower fabric layers. The fabric layers are TPU coated cloth. The first region  1  and the second region  2  are adjacent. A cavity is arranged in the first region  1 ; a sponge  11  is arranged in the cavity; the second region  2  is evenly provided with wavy transverse sealing lines  21  formed by pressing; the wavy transverse sealing lines  21  are arranged along the length direction of the inflatable cushion; and the wavy transverse sealing lines  21  separate the second region  2  into mutually communicated inflating cavities. The inflatable cushion body is provided with four air guide parts  3  used for inflating and deflating the cavity; the air guide parts are arranged between the first region  1  and the second region  2 ; and the air guide parts  3  are communicated with the cavity and the inflating cavities. The second region is provided with a first inflating port  22  for inflation and deflation; and the first inflating port  22  is arranged on one end of one fabric layer on the second region  2  away from the first region  1 . 
     In use, the first inflating port  22  is used for inflating the inflatable cushion. Gas enters the first region  1  from the second region  2 , and at the end of inflating, the hardness of the first region  1  is larger than the second region  2 . A human body can lie on the inflatable cushion with the back resting on the first region  1  and the legs resting on the second region  2 . After used in camping, the comfort of the inflatable cushion of the present invention is obviously higher than that of the traditional inflatable cushion filled with pure gas. At the same time, the first region  1  can be folded relative to the second region  2 . After use, the inflatable cushion is deflated through the first inflating port  22 . The volume of the first region  1  is relatively reduced, and the second region  2  is contracted and can be folded relative to the first region  1 , making it convenient to carry. 
     Embodiment 2 
     As shown in  FIG.  3   , an inflatable cushion comprises an inflatable cushion body. The inflatable cushion body comprises a first region  1  and a second region  2  formed by pressing an upper and a lower fabric layers. The fabric layers are TPU coated cloth. The first region  1  and the second region  2  are adjacent. The first region  1  is not communicated with the second region  2 . A cavity is arranged in the first region  1 . A sponge  11  is arranged in the cavity. The inflatable cushion body is provided with an air guide part used for inflating and deflating the cavity; the air guide part is a second inflating port  12 ; and the second inflating port  12  is located on one fabric layer on the first region  1 . The second region  2  is evenly provided with transverse sealing lines  21  formed by pressing; the transverse sealing lines  21  separate the second region into mutually communicated inflating cavities; the inflating cavities are arranged along the length direction of the inflatable cushion; the ends of the inflating cavities are mutually communicated; and the second region  2  is provided with a first inflating port  22  for inflation and deflation. 
     In use, the first inflating port  22  is used for inflating the second region  2 . Gas enters the second region  2 . The second inflating port  12  is inflated. Gas enters the first region  1 . After inflation, the hardness of the first region  1  is larger than the second region  2 . A human body can lie on the inflatable cushion with the back resting on the first region  1  and the legs resting on the second region  2 . After used in camping, the comfort of the inflatable cushion of the present invention is obviously higher than that of the traditional inflatable cushion filled with pure gas. 
     The first region  1  can be folded relative to the second region  2 . The first region  1  and the second region  2  can also be separately inflated and used to facilitate the adjustment of the height of a seat cushion. After use, the second region  2  and the first region  1  are deflated through the first inflating port  22  and the second inflating port  12 . The volume of the first region  1  is relatively reduced, and the second region  2  is contracted and can be folded relative to the first region  1 , making it convenient to carry. 
     Embodiment 3 
     As shown in  FIG.  4    to  FIG.  6   , the present embodiment is basically the same as embodiment 1, with the differences that: the present embodiment further comprises a third region  4  formed by pressing the upper and the lower fabric layers and provided with independent cavities, and the third region  4  is used as a back cushion. A connecting part  41  is arranged in the middle of the third region  4 . As shown in  FIG.  6   , cloth is connected between the upper and the lower fabric layers of the connecting part  41 , and the cloth is used to prevent the third region  4  from becoming spherical when inflating. A third inflating port  42  is connected to one fabric layer of the third region  4 . 
     In use, the first inflating port  22  is used for inflating the second region  2 . Gas enters the second region  2  and the first region  1 . The third inflating port  42  is used for inflating the third region  4 . Gas enters the third region  4 . After inflation, the hardness of the first region  1  is larger than the second region  2  and the third region  4 . A human body can lie on the inflatable cushion with the head resting on the third region  4 , the back resting on the first region  1  and the legs resting on the second region  2 . After used in camping, the comfort of the inflatable cushion of the present invention is obviously higher than that of the traditional inflatable cushion filled with pure gas. 
     The first region  1  can be folded relative to the second region  2 . After use, the second region  2 , the first region  1  and the third region  4  are deflated through the first inflating port  22  and the third inflating port  42 . The volume of the first region  1  is relatively reduced, and the second region  2  and the third region  4  can be folded relative to the first region  1 , making it convenient to carry. 
     Compared with the prior art, the present invention has the following beneficial effects: 
     By arranging the first region  1  and the second region  2 , the sponge  11  is arranged in the first region  1  and the inflating cavities are arranged in the second region  2 . In use, the sponge  11  can support an upper body of a user, so as to enhance the comfort of the user. The second region  2  can support the legs of the user. After deflating, the second region  2  can be retracted to reduce storage space, which is convenient to carry and light in weight. 
     Finally, it should be noted that the above embodiments are only used for describing the technical solutions of the present invention rather than limitation. Although the present invention is described in detail by referring to the above embodiments, those ordinary skilled in the art should understand that the technical solution recorded in each of the above embodiments can be still amended, or some technical features therein can be replaced equivalently.
