The top end wall 110 , the bottom end wall 120 and the peripheral wall 130 can jointly enclose a bed chamber 101 that is in the shape of a cube after inflating. There can be two reinforcing walls. For the convenience of description, the two reinforcing walls can be respectively the first reinforcing wall 140 and the second reinforcing wall 150. The top wall 110 and the peripheral wall 130 are sealed and connected together to form an upper bed edge chamber 102 surrounding the upper edge of the bed body chamber 101, and the upper bed edge chamber 102 may be in a rectangular ring shape after being inflated. The second reinforcement wall 150 can be sealingly connected with the top wall and the peripheral wall 130 at the same time, jointly forming the lower bed edge chamber 103 around the lower edge of the bed body chamber 101 , and the lower bed edge chamber 103 can be rectangular and ring-shaped after being inflated. When in use, both the second reinforced wall 150 and the bottom end wall 120 can be in contact with the ground to play a supporting role, and the lower bed formed by the second reinforced wall 150, the surrounding wall 130 and the bottom end wall 120 increases along the chamber 103.

The protruding peripheral wall 130 is set, and the air bed takes up little space, which is convenient for decoration.

Please refer to Fig. 4, at the same time, due to the setting of the inflatable chamber 104, when the air pump 200 is used to inflate the bed body chamber 101, the upper bed edge chamber 102 and the lower bed edge chamber 103, the gas is first delivered to the inflatable chamber 104 , and then through the inflatable chamber 104, the gas is distributed to the bed body chamber 101, the upper bed edge chamber 102 and the lower bed edge chamber 103, and only one air pump 200 is required to complete the inflation of multiple chambers, which simplifies the structure and reduces the cost . Moreover, when inflating, since the first air delivery pipe 210 is provided with a one-way valve 300, at the initial stage of inflation, the air pressure is small, and the one-way valve 300 is in a closed state, and the upper bed edge chamber 102 and the lower bed edge chamber 103 are firstly inflated. And after the inflation reaches the set amount, the one-way valve 300 is opened, so that the three chambers are inflated synchronously. Because the upper bed edge chamber 102 and the lower bed edge chamber 103 are inflated first, the upper bed edge chamber 102 and the lower bed edge chamber 103 are initially inflated and formed, and the bed body chamber 101 can be spread out during the molding process, thereby facilitating the bed body cavity The subsequent inflation of the chamber 101 is less prone to the situation that the folding and inflation of the bed body chamber 101 is blocked, and the inflation is smoother.
