The SPA pool further includes: an inflatable seat defining therein a second air chamber and disposed in the water cavity; a first nozzle assembly, wherein at least a part of the first nozzle assembly is accommodated within the inflatable seat, and a first end of the first nozzle assembly is in fluid communication with the water cavity. The pool body further includes a fluid pipeline disposed in the first air chamber, the fluid pipeline being in fluid communication with a second end of the first nozzle assembly, so that the first nozzle assembly provides fluid communication between the water cavity and the fluid pipeline.

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.

A pipeline system of an inflatable SPA is provided. The pipeline system includes an air inlet pipeline; a water inlet pipeline, distributed along a circumferential direction of the inflatable SPA; and a plurality of jets for massage, where each of the plurality of jets includes a first water inlet, a first air inlet and an air-liquid mixing outlet, the first air inlet is connected with the air inlet pipeline, the first water inlet is connected with the water inlet pipeline, and air and water can be mixed in each of the plurality of jets and sprayed from the air-liquid mixing outlet. The water with bubbles can be sprayed into pool cavity surrounded by an inner pool wall of the inflatable SPA, which can play a massage effect on users.

The present invention provides a above ground pool, comprising a flexible pool body. The flexible pool body comprises: a polygonal bottom sheet that comprises a plurality of edge portions; and a plurality of side sheets, each side sheet comprising a pool sidewall portion and a pool bottom portion, and each of the pool sidewall portions and each of the pool bottom portions being in the shape of an isosceles trapezoid. Each of pool sidewall portion comprises a first upper-base portion, a first lower-base portion and a first middle portion defined between the first upper-base portion and the first lower-base portion, and each of the pool bottom portion comprises a second upper-base portion, a second lower-base portion and a second middle portion defined between the second upper-base portion and the second lower-base portion. The first lower-base portion and the second lower-base portion coincide to define a junction of the pool sidewall portion and pool bottom portion. The first middle portions of the side sheets are successively connected to form a side wall of the above ground pool and the second middle portions are successively connected to form an outer ring of the bottom of the above ground pool. The second upper-base portions of the pool bottom portions are respectively connected to the edge portions of the bottom sheet. In the above ground pool of the present invention, joints are moved to a side wall of the swimming pool or the bottom of the swimming pool as much as possible, thereby reducing the length of joints passing through a heavily stressed area to the greatest extent, simplifying production processes, reducing costs, and reducing the probability of water leakage from the above ground pool.

An inflatable pool and a method for manufacturing the same are provided. An inner wall of the inflatable pool is provided with at least two inner wall joints each extending along a direction perpendicular to a pool base. After the inflatable pool is inflated, a corner is formed on the inner wall at a position of each of the inner wall joints; an outer wall is provided with at least one outer wall joint extending along the direction perpendicular to the pool base. According to the inflatable pool of the present application, the at least two inner wall joints and the at least one outer wall joint are provided on the inner wall and the outer wall respectively, which is easy for forming the corner on the inner wall after inflation, to form the polygon-shaped inflated pool, thus air leakage hardly occurs.

A pressure relief valve for an inflatable device, and an inflatable pool including the pressure relief valve are provided. The pressure relief valve includes: a valve seat configured to connect to the inflatable device; and a valve body. The valve body is disposed at least partially within the valve seat and includes a valve shell, comprising a vent hole therein, and a valve diaphragm arranged at a bottom of the valve shell. The valve diaphragm is moveable between a closed position in which the vent hole is closed and an open position in which the vent hole is open. The valve body further includes a spring and a valve diaphragm fixing part arranged around the vent hole. The valve shell and the valve diaphragm fixing part are connected to each other, and the spring is biased to push the valve diaphragm into the closed position.

Aspects of the present disclosure generally relate to a swimming pool having an internal lighting system. Certain embodiments may include an inflatable swimming pool including a wall and a base. The wall may include one or more inflatable chambers. One or more lighting elements may be interior to one or more of the inflatable chambers. The one or more lighting elements may be able to emit a plurality of colors. A color and/or intensity of the lighting elements may be controlled in accordance with a control command.

An inflatable product is provided, comprising: an inflatable chamber defined by a chamber wall; a tensioning member disposed in the inflatable chamber; and a connecting member disposed in the inflatable chamber. The connecting member includes a covering layer and a fiber layer disposed between the chamber wall and the covering layer. The tensioning member is sewn to the connecting member, and the connecting member is connected to the chamber wall.

An inflatable pool is provided, including an inflatable pool body including an inner wall, an outer wall and a bottom wall. The inner wall and the bottom wall define a water storage space, the inner wall and the outer wall form an inflatable chamber, and a cavity is defined between the inner wall and the outer wall. The inflatable pool further includes a pump device; a pool body connecting pipe including an inner end in communication with the water storage space and an outer end disposed within the cavity; and a pump connecting pipe including an outer end connected to the pump device, and an inner end including a connector detachably connected to the outer end of the pool body connecting pipe. A junction between the pool body connecting pipe and the pump connecting pipe is disposed within the cavity.
