In the first aspect, the side wall 104 of the pool body 100 is inflatable, and the bottom wall 102 of the pool body 100 is not inflatable. It can be understood that, in one or more example embodiments, the bottom wall 102 may include an interlayer internally provided with an elastic porous material that can improve the comfort of the bottom wall 102. The side wall 104 may comprise an outer wall 101, an inner wall 103, and an internal space 105 defined by the outer wall 101 and the inner wall 103. A plurality of tensioning components 106 may be provided in the internal space 105. The tensioning components 106 may be strip-shaped or sheet-shaped, and opposite ends of each tensioning component 106 may be respectively connected to the outer wall 101 and the inner wall 103 of the side wall 104. When the side wall 104 is inflated until the pressure of the internal space is greater than the ambient atmospheric pressure, the tensioning components 106 tension the outer wall 101 and the inner wall 103 of the side wall 104, so that the side wall 104 maintains a preset shape and stands relative to the bottom wall 102 to form a water-holding space 108 together with the bottom wall 102. In the first aspect, the side wall 104 forms a substantially square shape around the bottom wall 102.
(34) According to one or more example embodiments, the bottom wall 102 may be provided with an air channel and an air hole (not shown in the figure), the air channel being in communication with the water-holding space 108 via the air hole. The air channel may thereby be used to deliver pressurized air from an external air pump. The pressurized air may be released into the water held in the water-holding space 108 via the air hole, thereby forming bubbles to achieve a massage function.
(35) The seat comprises an inflatable stool 202. The inflatable stool 202 is provided in the water-holding space 108. In the first aspect, the seat comprises one inflatable stool 202. It can be understood that the seat may alternately comprise more than one inflatable stool. The inflatable stool 202 comprises a top sheet 204, a side enclosure sheet 206, a bottom sheet 208, and an inflation chamber 210. A top edge and a bottom edge of the side enclosure sheet 206 are respectively connected to the top sheet 204 and the bottom sheet 208 to together define the inflation chamber 210. A plurality of tensioning members 212 are provided in the inflation chamber 210. The tensioning members 212 may be strip-shaped or sheet-shaped, and opposite ends of each tensioning member 212 may be respectively connected to a lower surface of the top sheet 204 and an upper surface of the bottom sheet 208. The connections between the top sheet 204, the side enclosure sheet 206, the bottom sheet 208, and the tensioning members 212 can be achieved by means of welding or bonding.
(36) When the inflatable stool 202 is inflated until the pressure in the inflation chamber 210 is greater than the ambient atmospheric pressure, the tensioning members 212 tension the top sheet 204 and the bottom sheet 208, so that the inflatable stool 202 maintains a preset shape.
(37) The bottom sheet 208 of the inflatable stool 202 may have an integral connecting portion 214 (referring to
