Inflatable mattress structure with detachable air column

1. An inflatable mattress structure, comprising:

a cover made of flexible material and comprising a first top cover portion and a second bottom cover portion arranged opposite to the first top cover portion and integrally extended from the second bottom cover portion;

an inner space defined by the first top cover portion and the second bottom cover portion inside the cover;

at least one main divider comprising a first divider end tightly coupled with the first top cover portion and a second divider end tightly coupled with the second bottom cover portion to divide the inner space into at least two sub-inner spaces; and

an air column detachably arranged inside the inner space and passed through each of the sub-inner spaces one by one; and

an air valve tightly coupled with a free end of the air column; wherein

one of the at least two sub-inner spaces is adjacent to another one of the at least two sub-inner spaces and communicates with the another one of the at least two sub-inner spaces.

2. The inflatable mattress structure of claim 1 , wherein the cover further comprises a zipper arranged between the first top cover portion and the second bottom cover portion.

3. The inflatable mattress structure of claim 1 , wherein the at least one main divider comprises a plurality of main dividers, wherein each of the main dividers is independent of each other, wherein each of the main dividers does not contact each other.

4. The inflatable mattress structure of claim 1 , wherein the at least one main divider is a zigzag shape, wherein the at least one main divider is arranged between the first top cover portion and the second bottom cover portion, wherein the at least one main divider comprises at least one first divider end coupled with the first top cover portion and at least two second divider ends coupled with the second bottom cover portion, wherein each of the sub-inner spaces is a triangular shape.

5. The inflatable mattress structure of claim 1 , wherein the air column comprises a free end fixedly coupled with the cover and the air valve and a body contacting with the cover without fixedly coupling with the cover.

6. The inflatable mattress structure of claim 1 , wherein the air column comprises an elongated protrusion arranged on an inner surface of the air column and an outer surface arranged on an opposite side of the inner surface and exposed to the outside, wherein the elongated protrusion may be integrally and concavely extended from the inner surface towards an air column inner space defined for containing the air provided by the air valve.

7. The inflatable mattress structure of claim 1 , wherein the air column comprises an elongated supported member arranged inside an air column inner space of the air column, wherein the elongated supported member is a three-dimensional strip-shaped member that is integrally extended from the free end of the air column to a distal end of the air column.

8. An inflatable mattress structure, comprising:

a cover made of flexible material and comprising a first top cover portion and a second bottom cover portion arranged opposite to the first top portion:

an inner space defined by the first top cover portion and the second bottom cover portion inside the cover;

at least one minor divider arranged inside the inner space, wherein the inner space is divided to form at least two minor inner spaces by the at least one minor divider, wherein each of the minor inner spaces does not communicate with each other, wherein the at least one minor divider comprises a first minor divider end coupled with the first top cover portion and a second minor divider end coupled with the second bottom cover portion;

at least one main divider comprising a first divider end tightly coupled with the first top cover portion and a second divider end tightly coupled with the second bottom cover portion to divide the inner space into at least two sub-inner spaces; and

at least two air columns detachably arranged inside the inner space and passed through each of the at least two sub-inner spaces one by one;

an air valve tightly coupled with a free end of the air column; wherein

one of the at least two sub-inner spaces is adjacent to another one of the at least two sub-inner spaces and communicates with the another one of the at least two sub-inner spaces.

9. The inflatable mattress structure of claim 8 , wherein the cover further comprises a zipper arranged between the first top cover portion and the second bottom cover portion.

10. The inflatable mattress structure of claim 8 , wherein the at least two minor inner spaces are divided by the at least one main divider to form the at least two sub-inner spaces.

11. The inflatable mattress structure of claim 8 , wherein at least one air column comprises an elongated protrusion arranged on an inner surface of the air column and an outer surface arranged on an opposite side of the inner surface and exposed to the outside, wherein the elongated protrusion may be integrally and concavely extended from the inner surface towards an air column inner space defined for containing the air provided by the air valve.

12. The inflatable mattress structure of claim 8 , wherein at least one air column comprises an elongated supported member arranged inside an air column inner space of the air column, wherein the elongated supported member is a three-dimensional strip-shaped member that is integrally extended from a free end of the air column to a distal end of the air column.
