[0024] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, this embodiment designs an inflatable sponge pad, which includes an inflatable bag, a sponge layer, a pulling component and other components.

[0027] The inflatable bag has an inflatable cavity inside. When the inflatable cavity is inflated, the inflatable bag can expand and swell, and when the inflatable cavity is deflated, the inflatable bag can deflate and shrink. The top of the inflatable bag is the upper layer 1, and the bottom of the inflatable bag is the lower layer 7. The lower surface of the upper layer 1 is the top side wall of the inflatable cavity, and the upper surface of the lower layer 7 is the bottom side wall of the inflatable cavity.

[0028] The inflatable cavity has a sponge filling area and an air filling area that are connected to each other by air flow. The sponge filling area and the air filling area are stacked along the thickness direction of the inflatable bag, that is, any sponge filling area and any air filling area are in an upper and lower position relationship. The sponge filling area is filled with a sponge layer. When there are multiple sponge filling areas, different sponge filling areas are respectively provided with sponge layers. In addition, multiple sponge layers can also be provided in the sponge filling area. A pulling component is provided in the air filling area. The pulling component is connected between adjacent sponge layers or between the sponge layer and the inner wall of the inflatable cavity. When the inflatable bag is in an inflated state, the pulling component is in a tensioned state, so that the air filling area can be shaped after inflation, avoiding the problem of the middle part of the inflatable sponge pad being arched, and ensuring the flatness of the use surface of the inflatable sponge pad.

[0029] The pulling component includes an adhesive membrane and a tensioning rod 4. The adhesive membrane is attached to the surface of the sponge layer or the inner wall of the air-filled cavity. The tensioning rod 4 is fixedly connected to the adhesive membrane. The pulling component can be made of non-woven fabric and can be made into different shapes, such as Figure 1 and Figure 2 As shown in the figure, the tie rod 4 is square and tubular, and the tie rod 4 can also be in a C-shaped sheet (not shown in the figure). Figure 3 and Figure 4 As shown in the figure, the tensioning bar 4 includes an upper curved band 41 and a lower curved band 42; when adhesion membranes are connected above and below the tensioning bar 4, the two adhesion membranes are respectively an upper adhesion membrane 3 and a lower adhesion membrane 5, and a plurality of through holes are provided on the upper adhesion membrane 3 and the lower adhesion membrane 5. The upper curved band 41 passes through the plurality of through holes of the upper adhesion membrane 3, and the lower curved band 42 passes through the plurality of through holes of the lower adhesion membrane 5, and the upper curved band 41 and the lower curved band 42 are connected to each other.

[0030] When the number of the sponge filling area is one, the upper surface of the sponge layer is connected to the top side wall of the inflation cavity, the upper side of the pulling component is connected to the lower surface of the sponge layer, and the lower side of the pulling component is connected to the bottom side wall of the inflation cavity. Figure 1 and Figure 2 , when the direction of the reference figure changes, the position and name of the top side wall and the bottom side wall change accordingly. At this time, when the tie rod 4 adopts a square tube structure, the upper tube wall of the tie rod 4 is fixedly connected to the adhesion membrane below the sponge layer, and the upper tube wall of the tie rod 4 is connected to the bottom side wall of the inflation cavity or the adhesion membrane set on the bottom side wall of the inflation cavity is fixedly connected. When the tie rod 4 adopts a curved belt structure, the adhesion membrane below the sponge layer is the upper adhesion membrane 3, and the lower adhesion membrane 5 is set on the bottom side wall of the inflation cavity. The upper adhesion membrane 3 and the lower adhesion membrane 5 are pulled by the upper curved belt 41 and the lower curved belt 42, and the upper curved belt 41 and the lower curved belt 42 are connected to each other.

[0031] When the number of the sponge filling areas is two, the sponge layer includes an upper sponge layer 2 and a lower sponge layer 6 which are parallel to each other, and the lower sponge layer 6 is arranged below the upper sponge layer 2 with an interval; the upper surface of the upper sponge layer 2 is connected to the top side wall of the inflation cavity, and the lower surface of the lower sponge layer 6 is connected to the bottom side wall of the inflation cavity, and the pulling component is connected between the upper sponge layer 2 and the lower sponge layer 6. The relative position of the top side wall and the bottom side wall of the inflation cavity is referenced Figure 3 and Figure 4 , when the direction of the reference figure changes, the position and name of the top side wall and the bottom side wall change accordingly. The adhesion membrane fixedly connected to the lower surface of the upper sponge layer 2 is the upper adhesion membrane 3, and the adhesion membrane fixedly connected to the upper surface of the lower sponge layer 6 is the lower adhesion membrane 5. At this time, when the tie rod 4 adopts a square tubular structure, the upper tube wall of the tie rod 4 is fixedly connected to the upper adhesion membrane 3, and the upper tube wall of the tie rod 4 is fixedly connected to the lower adhesion membrane 5. When the tie rod 4 adopts a curved belt structure, the upper curved belt 41 passes through multiple belt holes of the upper adhesion membrane 3, and the lower curved belt 42 passes through multiple belt holes of the lower adhesion membrane 5, and the upper curved belt 41 is connected to the lower curved belt 42, so that the relative position of the upper sponge layer 2 and the lower sponge layer 6 can be fixed.

[0032] When the number of the sponge filling areas is greater than or equal to three, all the sponge layers are parallel to each other; adjacent sponge layers are separated by corresponding air filling areas; all the air filling areas of all the sponge layers are alternately stacked in the up-down direction; the upper surface of the top sponge layer is connected to the top side wall of the inflation cavity, and the lower surface of the bottom sponge layer is connected to the bottom side wall of the inflation cavity, and the pulling assembly is connected between adjacent sponge layers. In the two sponge layers at each air filling area, the adhesive membrane fixedly connected to the lower surface of the upper sponge layer is the upper adhesive membrane 3, and the adhesive membrane fixedly connected to the upper surface of the lower sponge layer is the lower adhesive membrane 5. At this time, when the tie rod 4 adopts a square tubular structure, the upper tube wall of the tie rod 4 is fixedly connected to the upper adhesive membrane 3, and the upper tube wall of the tie rod 4 is fixedly connected to the lower adhesive membrane 5. When the tensioning rod 4 adopts a curved belt structure, the upper curved belt 41 passes through multiple belt holes of the upper adhesion membrane 3, and the lower curved belt 42 passes through multiple belt holes of the lower adhesion membrane 5, and the upper curved belt 41 and the lower curved belt 42 are connected to each other, so as to fix the relative position of the upper sponge layer 2 and the lower sponge layer 6.

[0033] like Figure 5 As shown, based on the above structure, the side wall of the inflatable bag is provided with an inner concave portion 11, and the sponge layer is provided with a cut hole 21. The inner concave portion 11 passes through the cut hole 21 and is connected to the adhesive film to achieve the shape of the surface of the inflatable bag. By designing the position and shape of the inner concave portion 11, a concave flower structure can be formed on the surface of the inflatable sponge pad, thereby improving the aesthetics.

[0034] The connection method of the various components in this embodiment generally refers to hot-melt connection. In places where hot-melt connection is not possible, glue bonding, suturing and other methods can also be used, which will not be described in detail here.

[0035] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
