An above-ground pool is provided and includes a pool bottom and a pool wall, together defining a water storage space. The pool bottom includes a lower bottom sheet connected to the pool wall and an upper bottom sheet, the upper and lower bottom sheets connected in a ring region defining a sandwich region within the ring region. A porous elastic material is disposed between the upper bottom sheet and the lower bottom sheet in the sandwich region. A water drainage device includes a water drainage valve and a water drainage pipe, and the water drainage valve penetrating through the pool bottom and connected to the water drainage pipe beneath the pool bottom. A vent hole through the lower bottom sheet in the sandwich region provides communication between the porous elastic material and an environment external to the pool. The vent hole is disposed in a region of the pool bottom which is lifted off an external surface by the water drainage pipe beneath the pool bottom.

A drainage device for an above-ground pool, and an above-ground pool including the drainage device are provided. The drainage device includes a drainage pipe, with inlet and outlet ends, and a drainage valve connected to the inlet end of the drainage pipe. The drainage valve includes a water inlet periphery, defining a water inlet in fluid communication with the inlet end of the drainage pipe, and a connecting member disposed circumferentially around the water inlet periphery. The connecting member is radially spaced apart from the water inlet periphery. The connecting member may be formed by injection molding around the water inlet periphery.

Embodiments of the present disclosure provide systems and methods for a pool pump and one or more pool hoses. The pool pump may be connected to the pool through the one or more pool hoses. The system provides a pool pump comprising an outlet and an inlet. The inlet may connect to a first inlet hose. The first inlet hose may connect the pool pump to a three-way connection to the pool. The three-way connection may connect the first inlet hose to a second inlet hose and be in fluid connection with an interior of the pool. In some embodiments, the three-way connection may be attached to the pool.

A drainage device for an above-ground pool, and an above-ground pool including the drainage device are provided. The drainage device includes a drainage pipe, with inlet and outlet ends, and a drainage valve connected to the inlet end of the drainage pipe. The drainage valve includes a water inlet periphery, defining a water inlet in fluid communication with the inlet end of the drainage pipe, and a connecting member disposed circumferentially around the water inlet periphery. The connecting member is radially spaced apart from the water inlet periphery. The connecting member may be formed by injection molding around the water inlet periphery.

An inflatable massage pool comprises a pool body defining an inflatable cavity and a water receiving cavity. A water inlet assembly, located in the inflatable cavity, is configured to provide one of a filtered water flow or a massage water flow to the water receiving cavity. The water inlet assembly includes a water inlet pipe and a water flow guiding device. The water inlet pipe has a water inlet passage in fluid communication with the water flow guiding device for delivering one of the filtered water flow or the massage water flow to the water receiving cavity. The water inlet passage and the water flow guiding device delivers the massage water flow and the filtered water flow into the water receiving cavity in different paths or the same path, thereby reducing welding points on a pool wall, lowering the manufacturing cost, and reducing the difficulty in pipeline arrangement.

Aspects of the disclosed technology include a lighted inflatable pool including: a wall including a first inflatable chamber; a base; at least one lighting element disposed within the wall, the at least one lighting element being configured to emit light; and a receiver connected to the at least one lighting element, the receiver being configured to receive a command for controlling the lighting element and to control the at least one lighting element in correspondence with the command.

An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

A SPA bathtub and an operating unit therefore are provided. The operating unit includes a water circulation system including a diaphragm self-priming pump, a peristaltic pump, a water circulation pipeline, and a fluid switch assembly. The diaphragm self-priming pump operates before the peristaltic pump operates normally and stops operating after the peristaltic pump operates normally. During operation of the diaphragm self-priming pump, the fluid switch assembly is in a first operation state, so that water from the interior volume portion sequentially flows through the peristaltic pump, the diaphragm self-priming pump, the fluid switch assembly, and the water circulation pipeline and finally returns to the interior volume portion. During operation of the peristaltic pump, the fluid switch assembly is in a second operation state, so that the water sequentially flows through the peristaltic pump, the fluid switch assembly, and the water circulation pipeline and finally returns to the interior volume portion.

A water spraying device and an above-ground pool including the water spraying device are provided. The water spraying device includes: a sprayer assembly having a water inlet end, a water outlet end, and a first magnetic element disposed on the water inlet end; and a mounting assembly including a first end, a second end in fluid communication with the first end, and a second magnetic element disposed on the first end of the mounting assembly. The mounting assembly defines therein a water passage to the sprayer assembly. The first magnetic element is mutually attractive to the second magnetic element such that the water inlet end of the sprayer assembly and the first end of the mounting assembly are detachably connectable via the first magnetic element and the second magnetic element.

The invention discloses a non-pneumatic pool with inclined supports, which comprises a pool, wherein the pool includes a first hard sandwich, a first soft inner wall and a first soft outer wall. An outer side of the pool is provided with inclined supports, which include a second soft outer wall, a second soft inner wall and a second hard sandwich. The first soft outer wall of the pool is fixedly connected to a soft top portion of the inclined support through a first inclined support connection. When the non-pneumatic pool is in used, the whole pool is supported from the sides; multiple inclined supports form stable triangular structures with the pool walls to ensure the stability of the pool during use. Meanwhile, the inclined supports can be tightly attached to the pool walls during storage, which can save space and has strong practicability.
