FIGS.1and2respectively show a SPA pool100according to an example embodiment. The SPA pool100is inflatable and includes a pool body10. With reference toFIG.3, the pool body10includes a pool bottom11and a pool wall12with a first air chamber101. The pool bottom11and the pool wall12define a water cavity110. Specifically, the pool wall12includes an inner wall121and an outer wall122, and the pool bottom11forms the bottom of the water cavity110. Further, at least one inflatable seat including a second air chamber is arranged in the water cavity110. According to the example embodiment shown inFIGS.1to3, the at least one inflatable seat includes at least one of an inflatable seat chair21, an inflatable lounge chair22, and an inflatable stool23. Optionally, the inflatable seat chair21, the inflatable lounge chair22, and the inflatable stool23can be used by a single person or by two or more people. Take the inflatable lounge chair22as an example. The inflatable lounge chair22has a second air chamber102(shown inFIG.7). Optionally, the SPA pool may further include a nozzle assembly at least partially accommodated in the inflatable seat. Referring toFIG.2toFIG.5, the SPA pool100includes several first nozzle assemblies30, and these first nozzle assemblies30pass through the inflatable seat chair21and the inflatable lounge chair22. One end of the first nozzle assembly30is in fluid communication with the water cavity110, and the other end thereof is in fluid communication with a fluid pipeline40provided in the first air chamber101, so that the water cavity110and the fluid pipeline40are in fluid communication through the first nozzle assembly30. In an optional embodiment, the first nozzle assembly30may deliver water flow and/or air flow into the water cavity110.

With reference to the example shown inFIGS.4to6, the inflatable seat chair21, the inflatable lounge chair22, and the inflatable stool23may be inflated independently, and the inflatable air chambers of the inflatable seat chair21, the inflatable lounge chair22, and the inflatable stool23are the second air chambers102which are independent from the first air chamber101, that is, the first air chamber101and the second air chambers102are independent from each other. In this case, the pool body10and each inflatable seat (for example, the inflatable seat chair21, the inflatable lounge chair22, or the inflatable stool23) may be inflated separately. In another optional embodiment, the first air chamber101is in fluid communication with each second air chamber102, for example, the air chamber of the pool body10is in fluid communication with the air chamber of each inflatable seat (for example, the inflatable seat chair21, the inflatable lounge chair22, or the inflatable stool23) through, for example, a pipe or a through hole, so as to enable simultaneous inflation of each inflatable seat when a user inflates the pool body10.

The inflatable seat chair21optionally includes a backrest part and a bearing part, and the backrest part and the bearing part of the inflatable seat chair21together define a second air chamber of the inflatable seat chair21. The inflatable lounge chair22optionally includes a backrest part201and a bearing part202, as shown inFIG.6, and, compared with the bearing part of the inflatable seat chair21, the bearing part of the inflatable lounge chair22is further provided with a leg support2021. The backrest part201and the bearing part202of the inflatable lounge chair22together define the second air chamber102of the inflatable lounge chair22. At least one of the first nozzle assemblies30is arranged at the backrest part201to massage the back or waist of a user on the inflatable seat chair21or the inflatable lounge chair22, and the user can lie down for a massage on the inflatable lounge chair22.

The backrest part201of the inflatable lounge chair22may be provided with two first nozzle assemblies30, and the bearing part202of the inflatable lounge chair22may form a cushion. Each first nozzle assembly30passes through the backrest part201and is connected to the fluid pipeline40behind the backrest part201.

According to an aspect of one example embodiment, as illustrated inFIG.9, the inflatable lounge chair22may include an attachment sheet221, a bottom sheet222, a confining sheet223, and a top sheet224. The bottom sheet222, the confining sheet223, and the top sheet224may be hermetically connected (for example, by welding or glue) to form the second air chamber102and integrally, to form the backrest part201and the bearing part202. The attachment sheet221is connected to the pool bottom11of the pool body10and the bottom sheet222, respectively, by glue or welding, so that the bearing part202fixed to the pool bottom11, thereby fixing the inflatable lounge chair22to the pool bottom11. The inflatable lounge chair22further includes internal tensioning members225connected to the bottom sheet222, the top sheet224, and optionally connected to the confining sheet223. As shown inFIGS.7and8, when the second air chamber102is inflated, the internal tensioning members225provide a tension forming the inflatable lounge chair22into a desired shape. Further referring toFIGS.7to9, through holes, corresponding to the first nozzle assemblies30, are formed on the bottom sheet222and the top sheet224, and one or more first nozzle assemblies30are connected to the fluid pipeline40via the through holes. As shown inFIGS.7and9, the first nozzle assembly30has a nozzle301, and the nozzle301is connected to the pipe in the first nozzle assembly30and is attached to the through hole on the top sheet224.

According to one or more example embodiments, as shown inFIG.9, the first nozzle assembly30may be hermetically connected to the second air chamber102through a sleeve31. Ends of the sleeve31may be hermetically connected to the bottom sheet222and the top sheet224, respectively, and the first nozzle assembly30may extend through the sleeve31.

The first nozzle assembly30may pass through the backrest part201and may be connected to the fluid pipeline40at the side of the backrest part201. It should be understood that in this example, through holes corresponding to the first nozzle assembly30are formed on the confining sheet223and the top sheet224. That is, the water flowing through the first nozzle assembly30(optionally the water being mixed with gas) flows into the first nozzle assembly30from the through hole formed in the confining sheet223, and is ejected from the nozzle provided on the top sheet224.

According to one or more example embodiments in which an inflatable seat does not include a backrest part, for example, for an inflatable stool23, the first nozzle assembly may deliver water flow and/or air flow into the water cavity110from a seat surface of the inflatable stool, and the first nozzle assembly extends from the side of the inflatable stool to be connected to the fluid pipeline.

According to one or more example embodiments in which an inflatable seat does include a backrest part, taking the inflatable lounge chair22as an example, and referring toFIG.8, the backrest part201may be connected to the pool bottom11via tensioning belt assemblies32. Specifically, each tensioning belt assembly32includes a belt member321and a ring member322. The belt member321includes a tensioning belt and male and female buckles arranged on the tensioning belt, the tensioning belt is fixed to the bottom sheet222of the inflatable lounge chair22, the ring member322is fixed to the pool bottom11, and the tensioning belt passes through the ring member322with the male and female buckles locked, such that the backrest part201is limited to a height at a certain distance from the pool bottom11. In this way, when water is filled in the water cavity110, the tensile force provided by the tensioning belt assembly32limits the deformation of the backrest part201under buoyancy, so as to provide a smoothness of the first nozzle assembly and its water supply pipe.

According to one or more example embodiments, the first nozzle assembly30may be fixed to the fluid pipeline40through a fixed-length pipe. As illustrated inFIGS.5and6, the fluid pipeline40includes a water inlet pipeline41, wherein the water inlet pipeline41may extend around the water cavity110in the first air chamber101. The SPA pool100further includes a connecting assembly including first connecting assemblies411which provide fluid communication between the water inlet pipeline41and the first nozzle assembly30. The first connecting assemblies411are arranged in the first air chamber101and fluidly communicate with the first nozzle assembly30. It should be understood that the positions and quantity of the first connecting assemblies411correspond to those of the first nozzle assemblies30. Optionally, the fluid pipeline40further includes air inlet pipelines42. One end of an air inlet pipeline42is connected to a first connecting assembly411, and the other end thereof is connected to an opening on the outer wall122of the pool wall12and communicates with the outside, so that the first connecting assembly411is in fluid communication with an external space through the air inlet pipeline42. Notably, the first connecting assemblies411are attached to the inner wall121of the pool wall12and are in fluid communication with the first nozzle assembly30.

Optionally, the first nozzle assembly30may be connected to the first connecting assembly411through a pipe with an adjustable length, and whether the pipe is of a fixed length or an adjustable length, the pipe can be integrally provided with the first nozzle assembly30or may be provided separately. In addition, a first nozzle assembly30and a first connecting assembly411are optionally connected with each other in a rapidly detachable manner via a pipe.

It should be understood that the air inlet pipeline42is an optional configuration. By means of the air inlet pipeline42, when water flows to the first nozzle assemblies30through the water inlet pipeline41via the first connecting assemblies411, air external to the pool body10is sucked into the first connecting assemblies411and mixed with the water flow in the first connecting assemblies411. Jets of a water and air mixture may be ejected through the first nozzle assemblies30, the jets having an enhanced massage effect as compared with that provided by a water flow unmixed with air.

According to one or more example embodiments, referring toFIG.5andFIG.6, the SPA pool100may include at least one second nozzle assembly50having one end thereof in fluid communication with the water cavity110. The connecting assembly of the SPA pool100my further include a second connecting assembly412arranged in the first air chamber101and in fluid communication with the other end of the second nozzle assembly50. Optionally, the second nozzle assembly50may have a flow control valve, which is used to adjust the flow rate of a jet flowing out of the second nozzle assembly50, so as to correspondingly adjust the massage intensity. For example, in a case in which a stool23is provided, the second nozzle assembly50may be arranged at a position of the pool wall12above the stool23, thereby providing personalized massage intensity for a user using the stool. For the second connecting assembly412, the air inlet pipeline42is also an optional configuration.

According to one or more example embodiments, as illustrated inFIG.3,FIG.6,FIG.7andFIG.9, the pool bottom11may be provided with a first wave-making unit51, and the surface of an inflatable seat, such as the inflatable lounge chair22, may be provided with a second wave-making unit52, wherein the first wave-making unit51and the second wave-making unit52are provided with holes in fluid communication with the water cavity110, and spaces in the first wave-making unit51and the second wave-making unit52are in fluid communication with the water cavity110via the holes.

The SPA pool100may be provided with an interface assembly70, and the interface assembly70is used to connect to an external pump system (including a water pump assembly and an air pump assembly). The pump assemblies are used for supplying water to the fluid pipeline40, the first nozzle assembly30and the second nozzle assembly50, and for supplying air to the first wave-making unit51and the second wave-making unit52. For example, the water pump assembly in the pump system pumps water from the water cavity110, and the pumped water is pressurized and supplied to the fluid pipeline40, thus forming water circulation; and the air pump assembly sucks air from the outside atmosphere, and the sucked air is pressurized and supplied to the first wave-making unit51and the second wave-making unit52. The gas (e.g., air) supplied to the first wave-making unit51and the second wave-making unit52enters the water cavity110through the holes provided thereon to form bubbles. Optionally, a filter device is provided on a path of the water circulation (for example, on a water suction side of the interface assembly70or in the pump system), and the filter device can circularly filter the water in the water cavity110.

Optionally, the first wave-making unit51or the second wave-making unit52may include a wave-making zone and/or a wave-making pad (or a wave-making patch). With respect to the example embodiment shown inFIG.6, the first wave-making unit51includes a wave-making channel that forms the wave-making zone. The wave-making channel is arranged as a closed loop, and at least a part of the wave-making channel is distributed along the periphery of the inflatable seat. For example, as illustrated inFIG.4, the wave-making channel is arranged in an irregular ring shape, the outer contour of the ring shape is complementary to the outer contour of the space occupied by the inflatable seat chair21and the inflatable lounge chair22at the pool bottom11, so as to provide a wave-making massage effect for the space where backrest massage is not provided, and the inflatable stool23is optionally arranged in the annular space of the wave-making channel.

Optionally, the first wave-making unit51is in fluid communication with the second wave-making unit52.

As illustrated inFIGS.6and9, the inflatable lounge chair22further includes the leg support2021, as described above, and at least a part of the second wave-making unit52is located at or adjacent to the leg support2021to massage the legs or feet of the user. Specifically, the inflatable lounge chair22may further include a wave-making patch226, and the periphery of the wave-making patch226is connected to the top sheet224so that an air inlet space is formed between the wave-making patch226and the top sheet224. The wave-making patch226is provided with holes enabling the air inlet space to be in gas communication with the water cavity110. One end of the air inlet assembly60is connected to the top sheet224and the other end thereof is connected to the confining sheet223. As illustrated inFIG.9, the top sheet224and the confining sheet223are respectively provided with a first connecting hole2241and a second connecting hole2231corresponding to the air inlet assembly60, and both ends of the air inlet assembly60are respectively sealed with the first connecting hole2241and the second connecting hole2231. As illustrated inFIG.6, the air inlet assembly60is in gas communication with the first wave-making unit51through a vent pipe61, so that the pressurized air entering the first wave-making unit51is guided into the air inlet space formed by the wave-making patch226, through the vent pipe61and the air inlet assembly60, in sequence, and finally enters the water in the water cavity110through the holes on the wave-making patch226, forming bubbles for massage.

According to one or more example embodiments, the nozzle assemblies may be arranged on the inflatable seat. Furthermore, in addition to the backrest massage function, an inflatable seat according to one or more example embodiments may also provide a leg or foot massage function.
