As shown inFIGS.1to3, a non-inflatable above-ground pool according to one or more example embodiments comprises a pool body1and a control box14. The pool body1comprises a pool bottom11and a pool wall12surrounding the pool bottom11and connected to an edge of the pool bottom11. The pool bottom11and the pool wall12together enclose a water storage cavity100of the above-ground pool. The control box14is arranged outside the pool body1and comprises an air pump and a water pump that is integrated with a heater. The control box14is in fluid communication with the water storage cavity by means of a plurality of fluid pipelines passing through the pool wall12so as to allow the above-ground pool to have various functions such as filtering, heating and wave-making massage.

The pool bottom11may be a multi-layer structure sandwiched with a buffer material therein. For example, with reference toFIGS.5A to10B, the pool bottom11may comprise an upper bottom sheet113and a lower bottom sheet114which may be made of, for example, a polyvinyl chloride (PVC) film material, a PVC composite material or other polymer film materials, and a buffer layer115made of, for example, expanded polyethylene (EPE), flocculated polyester fiber, etc. An inner ring edge1133of the upper bottom sheet113adjacent to an edge1132thereof is welded to the lower bottom sheet114to enclose a pool bottom filling chamber101in which the buffer layer115is filled to achieve the functions of thermal insulation, buffering, etc.

The pool wall12comprises an inner wall121, an outer wall122, a top sheet123, and a first (or upper) connecting sheet124that connects the top sheet123to the outer wall122. Similar to the upper bottom sheet113and the lower bottom sheet114, the sheets of the pool wall12may all be made of, for example, a PVC film material, a PVC composite material or other polymer film materials, and form a body jacket10together with the pool bottom11. An upper edge of the inner wall121is welded to an inner edge of the top sheet123, and a lower edge1214of the inner wall121may be directly welded to the lower bottom sheet114(seeFIGS.5B,6B,7B and8B) or may be connected to the lower bottom sheet114by means of an additional second- (or lower) connecting sheet117(seeFIGS.9B and10B), which will be described in detail below according to one or more example embodiments. An upper edge of the outer wall122is detachably connected to a lower edge of a first (or upper) connecting sheet124by means of, for example, a connecting component17such as a zipper, a buckle, or a hook-and-loop fastener sewed thereon, an upper edge of the first connecting sheet124is connected to the outer edge of the top sheet123, and a lower edge1228of the outer wall122may be welded to an outer edge of the lower bottom sheet114(seeFIGS.5B,6B,9B,10B) or may be welded to an additional gasket125(seeFIGS.7B and8B), which will also be described in detail below according to one or more example embodiments. In this way, the inner wall121, the outer wall122, the top sheet123, the first connecting sheet124, and the lower bottom sheet114or the gasket125together enclose a pool wall filling chamber102for filling a wall body. It can be understood that the first connecting sheet124may be omitted, and the first connecting sheet124may be provided for the purpose of allowing the detachable connecting component17, such as a zipper, to be arranged on the outer side of the pool wall12and also preventing the arrangement of same on the outer edge of the top sheet123, which is convenient for a user to mount and remove the wall body.

For example, the support wall body13made of a foam material such as the EPE may be filled in the pool wall filling chamber. The EPE material has a good thermal insulation effect and has limited energy consumption. The support wall body13is formed by, for example, eight support units131sequentially joined in a circumferential direction, and a top portion130of each support unit131slightly protrudes out of the water storage cavity100of the pool as compared with a remaining part thereof. Each support unit131is configured to have, for example, an angled shape as shown, such that the support units are sequentially joined to form a polygonal support wall body13. It can be understood that the material of the support wall body13is not limited, for example, the support wall body may also be made of a foam material such as polyethylene (PE), polypropylene (PP), polystyrene (PS) or polyethylene terephthalate (PET). In addition, the shape of the support unit131is not limited, for example, the inner and outer surfaces of each support unit131may also be configured to be arc-shaped, such that the support units are sequentially joined to form a circular support wall body13.

As shown inFIGS.2to4, the above-ground pool comprises a body jacket10and support wall body13. The body jacket10of the above-ground pool is manufactured by, for example, sewing the connecting component17such as a zipper on the outer wall122and the first connecting sheet124, welding the first connecting sheet124to the top sheet123, welding the top sheet123to the inner wall121, allowing the inner wall121to be directly welded to the lower bottom sheet114or connected to the lower bottom sheet114by means of the additional second (or lower) connecting sheet117, and welding the outer wall122to the lower bottom sheet114or to the additional gasket125. When the above-ground pool is mounted by a user, the assembled body jacket10is unfolded, the support units131are sequentially placed into the pool wall filling chamber to form a circle of support wall body13, and then the connecting component17is closed to connect the outer wall122to the first connecting sheet124to achieve fixing and forming of the pool wall12, and finally the water inlet pipe, the water outlet pipe, the air inlet pipe and the air outlet pipe on the pool wall12are respectively connected to the corresponding interfaces on the control box14. When disassembled, it is only necessary to open the connecting component17and sequentially take out the support units131. Compared with an inflatable pool wall, the non-inflatable assembled pool wall is not prone to deformation, is convenient to assemble and use, and has good aesthetics.

The water pump in the control box14is in fluid communication with the water storage cavity100by means of the water inlet pipe153and the water outlet pipe154passing through the pool wall12. As shown inFIGS.1to3, the inner wall121is provided with an inner wall water inlet hole1215and an inner wall water outlet hole1216through which the water inlet pipe153and the water outlet pipe154respectively pass. The outer wall122is provided with an outer wall water inlet hole1225and an outer wall water outlet hole1226through which the water inlet pipe153and the water outlet pipe154respectively pass, and one of the support units131of the support wall body13is correspondingly provided with a first opening133through which the water inlet pipe153and the water outlet pipe154pass. Therefore, water in the water storage cavity100can enter the water pump via the water outlet pipe154, be filtered and heated, and then return to the water storage cavity100via the water inlet pipe153.

The air pump in the control box14is in fluid communication with the water storage cavity100by means of an air inlet pipe155passing through the pool wall12. As shown inFIGS.1to3, the inner wall121is provided with an inner wall air intake hole1217through which the air inlet pipe155passes, the outer wall122is provided with an outer wall air intake hole1227through which the air inlet pipe155passes, and one of the support units131of the support wall body13is correspondingly provided with a second opening134through which the air inlet pipe155passes. In addition, especially with reference toFIGS.5A to10B, the pool bottom11further comprises an annular surrounding strip116, and the surrounding strip116is connected to the edge1132of the upper bottom sheet113and is connected to the lower bottom sheet114along an outer ring edge1134, near the lower edge1214of the inner wall121, in particular near the side of the inner wall121facing the water storage cavity100. The surrounding strip116, an annular portion1131located between the edge1132of the upper bottom sheet113and the inner ring edge1133(in correspondence of which the upper bottom sheet113is connected to the lower bottom sheet114), and the lower bottom sheet114together enclose an annular wave-making channel111, and the wave-making channel111may be, for example, in fluid communication with the water storage cavity100by means of a plurality of jet holes1110uniformly arranged in a circumferential direction, and in fluid communication with the inner wall air intake hole1217by means of a connecting channel16. More specifically, one end of the connecting channel16may be welded to the inner wall121around the inner wall air intake hole1217, and the other end thereof may be welded to the surrounding strip116of the wave-making channel111. In this way, air entering the air pump from the outside can enter the wave-making channel111via the air inlet pipe155and the connecting channel16, and may then be sprayed to the water storage cavity via the jet holes1110of the wave-making channel111so as to provide a comfortable wave-making massage function for the user of the above-ground pool.

In addition, as shown inFIGS.1to3, the above-ground pool further comprises a water discharge pipe156passing through the pool wall12, and one of the support units131of the support wall body13is provided with a third opening135through which the water discharge pipe156passes. The first opening133, the second opening134and the third opening135may be arranged on the same support unit131of the support wall body13.

Another primary example embodiment of a non-inflatable above-ground pool, along with further example embodiments will be described below with reference toFIGS.11to20.

As shown inFIG.11, the non-inflatable above-ground pool comprises a pool body1, a pool cover2that may cover the top of the pool body1, and a pool cover liner3.

As shown inFIGS.11to17, the pool body1comprises a pool bottom11and a pool wall12that surrounds the pool bottom11and is connected to an edge of the pool bottom11. The pool bottom11and the pool wall12together define a water storage cavity100of the above-ground pool. The pool bottom11may have, for example, a multi-layer structure sandwiched with a buffer material such as pearl cotton.

More specifically, the pool wall12comprises an inner wall121, an outer wall122, a top sheet123, and a connecting sheet124. Similar to those of the pool bottom11, the components of the pool wall12may all be made of a polyvinyl chloride (PVC) film material, for example, and form a body jacket together with the pool bottom11. An upper edge of the inner wall121is connected to an inner edge of the top sheet123by means of welding, a lower edge of the inner wall121is connected to the pool bottom11by means of welding, an upper edge of the outer wall122is detachably connected to a lower edge of the connecting sheet124by means of a connecting component17such as a sewed zipper (see the enlarged part inFIG.15andFIG.16), a release buckle, or a hook-and-loop fastener, a lower edge of the outer wall122is connected to an outer edge of the pool bottom11by means of welding, and an upper edge of the connecting sheet124is connected to an outer edge of the top sheet123by means of welding. In this way, the inner wall121, the outer wall122, the top sheet123, the connecting sheet124, and the pool bottom11together define a filling chamber102for filling the wall body13. It can be understood that the connecting sheet124is not necessarily provided, and the purpose of providing the connecting sheet is to allow the detachable connecting component17, such as a zipper, to be arranged on the outer side of the pool wall. In addition, the arrangement of the detachable connecting component on the outer edge of the top sheet of the pool should be avoided, which makes it convenient for a user to install and remove the wall body.

As shown inFIG.13andFIG.18, for example, a support wall body13made of a foam material, such as polyethylene (PE), polypropylene (PP), polystyrene (PS) or polyethylene terephthalate (PET), is filled in the filling chamber102of the pool wall12, the support wall body13is formed, for example, of a plurality of support units spliced in sequence along the circumferential direction, and a top portion130of each support unit slightly protrudes outward relative to the rest. One of the support units131A is thicker than the other support units and is provided with a wall body opening132. An outer surface1311of the support unit131A is configured to have an arc shape, and an inner surface1312thereof is configured to have a flat shape. The wall body opening132is shaped and sized to coordinate with the control box, that is, the wall body opening132can accommodate the control box therein. With the exception of this support unit131A, the inner and outer surfaces of each of the other support units are each configured to have an inward angled shape, so that the support units are spliced in sequence to form a polygonal support wall body13. It can be understood that the shape of the support unit is not limited, for example, the inner and outer surfaces of each support unit can be configured to have an inward arc shape, so that the support units are spliced in sequence to form a circular support wall body. Compared with an inflatable pool wall, the non-inflatable assembled pool wall is not easily deformable, is easy to assemble and use, and has good aesthetics.

As shown inFIGS.11to17, the pool body1further comprises a control box14integrated with a water pump and an air pump. A filter and a heater are integrated in the water pump. The control box14is embedded in the wall body opening132and is in fluid communication with the water storage cavity via the inner wall121, so as to allow the above-ground pool to have various functions such as filtering, heating, and wave-making massage.

More specifically, the inner wall121is provided with a water inlet hole1211and a water outlet hole1212that allow the water pump to be in fluid communication with the water storage cavity, and the pool body1further comprises a water inlet joint151and a water outlet joint152. The water inlet joint151passes through the water inlet hole1211and is tightly connected to the water pump, for example, by means of screw fitting, and allows the inner wall121to be clamped between the water inlet joint151and the water pump. The water outlet joint152passes through the water outlet hole1212and is tightly connected to the water pump, for example, by means of screw fitting, and allows the inner wall121to be clamped between the water outlet joint152and the water pump. Therefore, the water in the water storage cavity can enter the water pump via the water inlet joint151, be filtered and heated, and then return to the water storage cavity via the water outlet joint152.

As shown inFIGS.19and20, according to an alternate example embodiment, the pool body1may further comprise a first sealing member181arranged around the water inlet hole1211and between the inner wall121and the water inlet joint151, and a second sealing member182arranged around the water outlet hole1212and between the inner wall121and the water outlet joint152. Since the water inlet joint151and the water outlet joint152respectively pass through the water inlet hole1211and the water outlet hole1212and are then connected to the water pump, these sealing members are provided to ensure the tightness of the inner wall121to prevent the water in the water storage cavity from entering the pool wall12through the water inlet hole1211and the water outlet hole1212. Optionally, the first sealing member181and the second sealing member182may be fixedly arranged on the inner wall121.

In addition, the outer wall122is provided with an air inlet hole1223, and the inner wall121is provided with an air outlet hole1213that allows the air pump to be in fluid communication with the water storage cavity. In this example embodiment, the pool bottom11comprises an annular wave-making channel111, the wave-making channel111being arranged adjacent to the inner wall121and in fluid communication with the water storage cavity through a plurality of jet holes1110evenly arranged along the circumferential direction, and the pool body1further comprises a connecting channel16that allows the air outlet hole1213to be in fluid communication with the wave-making channel111, with one end of the connecting channel16being connected to the inner wall121around the air outlet hole1213by means of welding, and the other end thereof being connected to the wave-making channel111by means of welding. In this way, the air entering the air pump through the air inlet hole1223can enter the annular wave-making channel111through the air outlet hole1213and the connecting channel16, and is then sprayed into the water storage cavity through the jet hole of the wave-making channel111, so as to provide a comfortable wave-making massage function for a user of the pool. In this example embodiment, the pool bottom11is further provided with a pool bottom opening112. The pool bottom opening112is adapted to the bottom of the control box14, and may not only be used as an auxiliary air inlet, but also used for positioning the control box14during assembly of the pool wall12.

In an example alternative implementation shown inFIG.20, the pool body1may further comprise an air outlet pipe19that is tightly connected to the air pump, for example, by means of screw fitting, and the air outlet pipe19passes through the air outlet hole1213and allows the air pump to be in fluid communication with the connecting channel16. In addition, the pool body1may further comprise a third sealing member183arranged around the air outlet hole1213and between the inner wall121and the air outlet pipe19.

In addition, the control box14comprises a control panel141and a power cord142that extend from the body of the control box, and the outer wall122is provided with a panel hole1221for the control panel141to pass through and a cord hole1222for the power cord142to pass through. The control panel141protruding from the pool wall12through the panel hole1221is used by a user to start, stop, or adjust the various functions of the control box14mentioned above.

Since the control box14is integrated into the pool wall12of the pool body1rather than placed outside the pool body1, the pipeline structure of the pool may be simplified without affecting the function of the poor, and the entire pool has a concise appearance and does not occupy additional floor space.

As shown inFIG.11, the pool cover2is used to cover the water storage cavity and is detachably connected to the outer wall122, so as to provide a thermal insulation effect before a user enters the pool. In this embodiment, the outer edge of the pool cover2is provided with a plurality of first inserts21, and the outer wall122is provided with a plurality of second inserts1224that may be in insert-fit with the first inserts21. Of course, this detachable connection manner is not restrictive, and these inserts may also be replaced with zippers, hook-and-loop fasteners and other components.

In addition, the pool cover liner3attached to the bottom of the pool cover2is shaped and sized to adapt to the water storage cavity. The pool cover liner3may have an inflatable structure, or may be additionally provided with a thermal insulation layer inside, and thus can be used together with the pool cover2to further reduce the heat loss of the above-ground pool.
