[0063] For the purposes of promoting an understanding of the principals of the disclosure, reference will now be made to the embodiments illustrated in the drawings, which are described below.

Embodiment 1

[0067] As shown in FIGS. 1 to 6 and 12-14, the present disclosure provides a nozzle assembly 100 for a SPA pool. The nozzle assembly 100 may comprise a first nozzle 1, a second nozzle 2, and a water pipe 3. Although two nozzles are shown, additional nozzles may be included.

[0068] The first nozzle 1 and the second nozzle 2 each have an air inlet end 112, and the air inlet ends 112 are respectively connected to an air inlet valve 5 through an air pipe 4 and an adapter 6, 6’. Air pipes 4 are shown vertically oriented relative to one another in FIG. 2, and air pipes 4’ are shown horizontally oriented relative to one another in FIG. 12. Other orientations of the air pipes 4, 4’ are contemplated.

[0069] Although the illustrated embodiments depict air inlet valve 5 in fluid communication with ambient air, air valve 5 may also receive pressurized air. Air inlet valve 5 has an internal volume, and air received in the internal volume is subsequently diverted through adapter 6 to a plurality of air pipes 4 in fluid communication with the first nozzle 1 and the second nozzle 2 via respective air inlet ends 112. [0070] The water inlet end of the first nozzle 1 is connected to the inlet waterway 15, and the water inlet end of the second nozzle 2 is connected to the inlet waterway 15 through the water pipe 3.

[0071] Advantageously, the nozzle assembly for a SPA pool discussed herein can achieve at least two nozzles connecting to the same inlet waterway 15 and air inlet valve 5. This simplifies the pipeline connection.

[0072] Because two nozzles are connected to the same inlet waterway 15, it would be very inconvenient if one nozzle was turned off and the other nozzle could not be used. [0073] Therefore, the first nozzle 1 and the second nozzle 2 each comprise a nozzle base 11 and a nozzle head 12. The nozzle base 11 is formed with the water inlet end 111 and the air inlet end 112. The nozzle base 11 of each first nozzle 1 also includes a water outlet 113. A face of the nozzle head 12 may include grooves, notches, protrusions, or the like to assist the user in rotating the nozzle head.

[0074] The nozzle head 12 is inserted into the nozzle base 11 and rotates between a first position and a second position relative to the nozzle base 11 under external force. The nozzle head 12 has a water inlet hole 121, a water outlet 122, and an internal fluid passageway 123 connecting the water inlet hole 121 to the water outlet 122. When the nozzle head 12 is in the first position, the water inlet hole 121 is aligned with the water inlet end 111 of the nozzle base 11 such that water can flow from the inlet waterway through the water inlet end 111 of the nozzle base 11, through the water inlet hole 121 of the nozzle head 12, and out of the nozzle head 12 into the water cavity of a spa or pool. In the first position, water may be communicated from the inlet waterway 14 to the second nozzle 2 through an interior 124 of the nozzle head 12 of the first nozzle 1. When the nozzle head 12 is in the second position, the water inlet hole 121 is staggered relative to the water inlet end 111 of the nozzle base 11 to prevent water from entering the nozzle head 12 from the inlet waterway 15. In the second position, water may be communicated from the inlet waterway 15 to the second nozzle 2 externally to the nozzle head 12 of the first nozzle 1 via a bypass 125 formed by the nozzle head 12 of the first nozzle 1 and the nozzle base 11 of the first nozzle 1. Regardless of the position of nozzle head 12, the nozzle base 11 remains connected to the water inlet end 111 at all times. In this way, as depicted in FIGS. 8-11, rotating two nozzle heads 12 can turn off the nozzles separately, and when the nozzle head 12 of the first nozzle 1 rotates to the second position, the water can still flow from the inlet waterway 15 to the second nozzle 2 normally. Therefore, even if the first nozzle 1 is turned off, the second nozzle 2 can still be used normally. Similarly, the second nozzle 2 may be turned off and the first nozzle 1 may remain in the on position.

[0075] As water flows through the nozzle head 12 of the first nozzle 1 and the second nozzle 2, respectively, the water flow effects a drop in pressure at the air inlet end 112 of the first nozzle 1 and the air inlet end 112 of the second nozzle 2. The pressure drop draws in ambient air through air inlet valve 5. Thus, when, for example, the nozzle head 12 of the first nozzle 1 is in the second position, there is no water flow through the nozzle head 12 to create a drop in pressure at the air inlet end 112 of the first nozzle 1, and thus no ambient air is drawn into the first nozzle 1.

[0076] Although in the illustrated embodiments, ambient air is drawn into the first nozzle 1 and the second nozzle 2, in alternative embodiments, a pump may supply pressurized air to the first nozzle 1 and the second nozzle 2.

[0077] In the illustrated embodiment, to achieve the connection of two nozzle bases 11 through the water pipe 3, the nozzle base 11 of the first nozzle 1 extends out of the water pipe 3 on the side away from the water inlet end 111. The water pipe 3 is inserted into the nozzle base 11 of the second nozzle 2 and fixedly connected to the second nozzle 2 through a fixing nut 13. A stopper 14 may fit within fixing nut 13 and may improve the seal between water pipe 3 and the water inlet end 111 of the nozzle base 11. Stopper 14 may be formed with interlocking features, such as ridges and valleys, that mate with interlocking features formed in the water inlet end 11 of the nozzle base 11 of the second nozzle 2. The stopper 14 may prevent the fixing nut 13 from deforming a sealing gasket 17.

[0078] The present disclosure further provides a SPA pool, which comprises a pool body and a nozzle assembly arranged on the pool body. The nozzle assembly may be the nozzle assembly as described above.

[0079] The pool body may be an inflatable spa or pool, or a frame pool. In the case of an inflatable spa or pool, having multiple nozzles connected to a common water inlet and/or a common air inlet may reduce the amount of conduits needed internal to the air cavity of the inflatable pool resulting in a reduction in the number of parts and weight of the inflatable pool in the deflated state. [0080] FIG. 14 depicts an exemplary inflatable spa 200. Inflatable spa 200 includes a bottom wall 204, an internal side wall 206, and an external side wall 208. Internal side wall 206 and external side wall 208 cooperate to define an air cavity 210. In embodiments, internal side wall 206 and external side wall 208 cooperate with bottom wall 204 and a top wall 209 to define air cavity 210. Internal side wall 206 and bottom wall 204 cooperate to define a water cavity 212.

[0081] Inflatable spa 200 may also include a controller 200 and pump 222. Although not pictured, additional components, such as a water filter, are contemplated.

[0082] A feed line 224 may supply water from the water cavity 212 to an inlet of pump 222, and a return line 226 may transport pressurized water from an outlet of pump 222 to the inflatable pool. In embodiments, return line 226 may transport a portion of the pressurized water directly to the water cavity 212 and a portion of the pressurized water to a main supply line 228 disposed in the air cavity 210. Main supply line 228 may span the circumference of the air cavity 210 or less than the circumference of the air cavity 210. Main supply line 228 may be a single line or may be formed of multiple supply lines that make up the main supply line 228.

[0083] As shown in FIG. 14, a plurality of nozzle assemblies 100 are disposed in the air cavity 210. The nozzle assemblies 100 are connected to the main supply line 228 such that the inlet waterway 15 of each nozzle assembly 100 connects to the main supply line 228 to receive pressurized water from the pump 222.

[0084] As suggested above, if all the first nozzles 1 and second nozzles 2 of the plurality of nozzle assemblies 100 are in an off position, the return line 226 will transport the pressurized water directly into the water cavity 212. This way, even if the user does not wish to use the nozzle features, the water cavity 212 may still receive filtered water from the controller 220.

Thus, the first nozzle 1 and the second nozzle 2 are connected via water pipe 3, which may be a hose.

[0086] To install the water pipe 3, the nozzle base 11 of the first nozzle 1 has a water outlet end 113 on the side away from the water inlet end 111. The water pipe 3 is connected between the water outlet end 113 of the first nozzle 1 and the water inlet end 111 of the second nozzle 2.
