A gap 122 is formed between the top of the laminated elements 120 and the top wall 102. A gap 124 is formed between the bottom of the laminated elements 120 and the bottom wall 104.

According to Figure 4 and Figure 5, the laminate wall 120 comprises a pattern or screen layer 130 formed by an open porous pattern of interwoven or interwoven yarns or fibers (eg, a fabric or a fabric having a weft open) and two tie layers 132. The two tie layers 132 are bonded to the top and bottom surface of the first layer 130, respectively, to hold the first layer 130. The tie layer(s) 132 may be made of PVC (polyvinyl chloride), TPR (thermoplastic rubber), EVA (ethylene vinyl acetate) or fabric.

The disclosures shown in the figures will now be described in more detail and initially with reference to Figures 1-3, an inflatable swimming pool or whirlpool 100 is shown including a top wall 102, a bottom wall 104, an inner wall or inner wall 106, and an outer or outer wall 108. The upper wall 102 is an annular wall and is connected to the upper ends of the inner wall 106 and the outer wall 108. The lower wall 104 is also an annular wall and is connected to the lower ends of the inner wall 106 and the outer wall 108. The diameter of the outer wall 108 is larger than the diameter of the inner wall 106. The upper wall 102, the lower wall 104, the inner wall 106 and the exterior wall 108 of the whirlpool or swimming pool may be constructed of polyvinyl chloride (PVC), thermoplastic rubber (TPR), ethylene vinyl acetate (EVA), thermoplastic polyurethane elastomer (TPU), or other materials. suitable materials.

The whirlpool or pool 100 includes an inflatable bladder 110 formed between the top wall 102, bottom wall 104, inner wall 106, and outer wall 108. The bladder 110 includes one or more suitable air vents. (not shown) to inflate and deflate the bladder 110. In certain cases, the bladder 110 may be inflated to a relatively high pressure, greater than about 5.52 kPa (0.8 psi). For example, the air chamber 110 can be inflated to a pressure of about 6.20kpa, 6.90kpa, 7.58kpa, 8.27kpa, 8.96kpa, 9.65kpa, 10.34kpa, 11.03kpa or more (0.9 psi, 1.0 psi, 1.1 psi, 1.2 psi, 1.3 psi, 1.4 psi, 1.5 psi, 1.6 psi or more). These pressures can be approximately 1.5 or 2 times higher than the pressures used to inflate traditional inflatable products.

The whirlpool 100 also includes a water cavity 112 formed by the bottom wall 104 and the inner wall 106.

Within the bladder 110, the pool 100 also includes a plurality of ^{internal tensioning, interval, or reinforcing} elements or structures 120 ^{that maintain the shape of the pool} 100 ^{when the bladder} 110 ^is pressurized. The stressing structures 120 can improve the strength of the pool 100 by allowing the ^{air chamber 110 to withstand relatively high internal pressures, as explained above, while providing comfort to the user sitting in the pool or whirlpool.} 100 ^.

As shown in Figures 1 and 2, the tensioning structures 120 are arranged vertically and radially in the air chamber 110 in an annular pattern. As shown in Figure 3, each tensioning structure 120 can be attached to inner wall 106 and outer wall 108, as explained below with reference to Figures 7 ^and 8 ^{. In addition, each tensioning structure 120 may be spaced apart from top wall 102 and bottom wall 104} to define an upper gap 122 relative to top wall 102 and a lower gap 124 relative to bottom wall 104.

Referring to Figures 4-6, each tensioning structure 120 may include a porous layer or sheet 130 and one or more tie layers or sheets 132 bonded (eg, laminated) to the porous layer 130. In the disclosure illustrated in Figure 5, porous layer 130 is sandwiched between two tie layers 132, with tie layers 132 bonded ^{to both the top and bottom surfaces of porous layer 130. In the illustrated disclosure of Figure} 6 ^, the porous layer 130 is bonded to a single bonding layer 132, with the single bonding layer 132 bonded to either the top surface 160 or the bottom surface 162 of the porous layer 130.

Except for the upper gap 122 and lower gap 124 in the tensioning structure 120, the tensioning structure 120 may have a generally rectangular shape, as shown in Figure 4. In this disclosure, the porous layer 130 includes an outer perimeter generally rectangular 150 formed by edges 152a-d, and tie layer 132 includes a generally rectangular outer perimeter 154 formed by edges 156a-d. Tie layer 132 may span the entire porous layer 130, as shown in Figure 5, such that the outer perimeter of the tie layer generally overlaps the outer perimeter of the porous layer. It is also within the scope of the present description that the tie layer may encompass a part of the porous layer.

The porous layer 130 may be formed from a plurality of weaves or frame elements 134 that define a plurality of holes or pores 136 therebetween, as shown in Figure 4. When the bladder 110 is pressurized, the elements The frame members 134 may be placed in tension to help maintain the shape of the whirlpool 100. Adjacent frame members 134 may be spaced ^{regular intervals to provide the tension frame} 120 ^{with a substantially constant tensile strength} .

Each pore 136 of the porous layer 130 may be enclosed or completely surrounded by elements of the intersecting structure 134 within a range of 360 degrees. A plurality of pores 136 may be located entirely within the outer perimeter 154 of tie layer 132 to facilitate attachment to tie layer 132, as described below. It is also within the scope of the present disclosure that other pores 136 may be located outside the outer perimeter 154 of bonding layer 132. The size and shape of each pore 136 may vary depending on the thickness and orientation of surrounding elements of the bonding layer. structure 134. Porous layer 130 may also include, for example, a plurality of open spaces 158 that are partially surrounded by elements of structure 134 and partially exposed along outer perimeter 150.

In the illustrated disclosure of Figure 4, the frame elements 134 are arranged in a grid pattern, including a first set of parallel spaced frame elements 138 and a second set of parallel frame elements 139. In this grid pattern, the first set of frame elements 138 are transverse to the second set of frame elements 139, such that the first set of frame elements 138 intersects the second set of frame elements 139. structure 139. In Figure 4, the grid pattern is rotated approximately 45 degrees from a horizontal axis to resemble a lattice, so that the first set of elements of structure 138 slopes upward from the horizontal axis (p. g., approximately 45 degrees from the horizontal axis), and the second set of frame elements 139 is angled downward from the horizontal axis (eg. approximately -45 degrees from the horizontal axis) and is substantially perpendicular to the first set of frame elements 138. In Figure 4, evenly spaced diamond-shaped pores 136 are formed between adjacent frame elements 134 . Adjacent pores 136 may also be tilted up and down relative to the horizontal axis.

In accordance with the present disclosure, the porous layer, pattern, or screen 130 may be constructed of a mesh, fabric, or screen with interwoven yarns, fibers, or wires as individual structure elements 134. Certain disclosures use fibers of a polyester, nylon, or cotton. As shown in Figure 4, each element of structure 134 may include a first terminal end 170 located at one edge (e.g., edge 152a) of porous layer 130 and a second terminal end 172 located at one edge. opposite (eg, edge 152c) of porous layer 130.

As explained above, each tensioning structure 120 can be coupled to inner wall 106 and outer wall 108 through suitable coupling techniques, such as, for example, high-frequency coupling, hot coupling (eg, melting, welding) or adherence (eg, gluing). In the illustrated disclosure of Figure 7, the tensioning structure 120 is attached directly to the inner wall 106 and the outer wall 108 ^{along a seam 142. In the illustrated disclosure of Figure} 8 ^{, the tensioning} structure 120 is attached. indirectly ^coupled to the inner wall 106 and the outer wall 108 through the use of intermediate connection layers 140. More specifically, the tensioning structure 120 is coupled to the intermediate connection layer 140 through a first seam 144, and the layers Intermediate connecting pads 140 are attached to inner wall 106 and ^{outer wall 108 through a second seam 146. As shown in Figures 7 and} 8 ^{, seams 142, 144, 146} may be located along the edges (eg, edges 152a, 156a and edges 152c, 156c) of the tensioning structure 120. Turning to Figure 4, the seams 142, 144, 146 are shown to extend in a vertical direction along I edge them s on the right side 152a, 156a, of the tensioning structure 120 for attaching the tensioning structure 120 to the adjacent interior wall 106 and along the left side edges 152c, 156c of the ^{tensioning structure} 120 ^{for attaching the tensioning structure. tensioned} 120 ^{to the adjacent outer wall 108, for example.}

According to an illustrative disclosure, frame elements 134 are oriented transversely (i.e., not parallel) to seams 142, 144, 146. In Figure 4, frame elements 138 are tilted from side to side in the vertical direction. . In this disclosure, as the vertical seams 142, 144, 146 and any lines parallel to the vertical seams 142, 144, 146 pass through the tensioning structure 120, the vertical line will intersect at least one pore 136 or open space. 158 between the elements of the structure 134. In other words, ^{there is no vertical line that passes completely through the tensioning structure} 120 ^{along one element} of the structure 134 without intersecting at least one pore 136 or open space 158 adjacent to frame element 134. In Figure 4, frame elements 138 are also oriented transverse to any horizontal line that is perpendicular to seams 142, 144, 146. As explained above, frame elements 138 are tilted up and down in the horizontal direction. In this disclosure, as any horizontal line perpendicular to the vertical seams 142, 144, 146 passes through the tensioning structure 120, the horizontal line will intersect at least one pore 136 or open space 158 between the elements of the structure 134. In In other words, there is no horizontal line that passes completely through the tensioning structure 120 along a structure element 134 without intersecting at least one pore 136 or open space 158 adjacent to the structure element 134.

To facilitate secure connections between the stressing structure 120, inner wall, outer wall 108, and optional intermediate connecting layers 140, the materials used to construct these adjacent layers may be the same or otherwise compatible. For example, if inner wall 106, outer wall 108, and optional intermediate connecting layers 140 are constructed of PVC, TPR, EVA, or TPU, at least a portion of corresponding stress structure 120 may also be constructed of PVC, TPR, or TPU. , EVA or TPU. In cases where adjacent layers are fused using high-frequency radiation, for example, compatible materials may have the same or similar melting points to ensure that the materials fuse, mix, and form secure connections. In accordance with the present description, at least the bonding layer 132 of the tensioning structure 120 may be constructed of a compatible material. The porous layer 130 of the tensioning structure 120 ^{, in contrast, may be constructed of a different, potentially incompatible (e.g., higher melting) material,} potentially stronger, because the pores 136 in the porous layer 130 may admit bonding of adjacent compatible materials (e.g., one or more bonding layers 132, whirlpool interior wall 106, whirlpool exterior wall 108, and/or optional intermediate connecting layers 140) through the pores 136 in the porous layer 130. For example, the bonding layer 132 of the tensioning structure 120 can be constructed of a compatible material such as PVC, TPR, EVA, or TPU, while the porous layer 130 of the structure tensioning 120 ^{may be constructed of a fabric or screen.}

The ^{first check valve 260 also includes a first valve core} 266 ^having a stem 268, a head 270, and a hemispherical sealing member 272 coupled to the head 270. The first check valve 260 further includes a first elastic spring 274 that interacts With the first valve core 266, the first elastic spring 274 wraps around the stem 268 of the first valve core 266 with one end positioned against the head 270 and the other end positioned against the first housing 262.

In operation, the first valve core 266 moves longitudinally through the internal cavity 264 of the first housing 262 between a sealed or closed position and an open position. In the sealed position, sealing member 272 of first valve core 266 extends into supply cavity 246 and seals against valve seat surface 248, as shown in Figure 18. In the open position , the sealing piece 272 of the first valve core 266 exits the supply cavity 246 and separates from the valve seat surface 248.

The first housing 262 may also include a drain valve 280 coupled to a drain port 282 from the first housing 262, as shown in Figures 17 and 18. The drain valve 280 includes an upper housing 284 having a surface of uneven or corrugated upper valve seat 286 and a lower housing 288 having a lower valve seat surface 290. The upper housing 284 and lower housing 288 cooperate to define an internal drain cavity 292 in fluid communication with the drain port. 282.

In operation, the second valve core 330 moves longitudinally through the locating stem 324 of the second valve holder 320 between a sealed or closed position and an open position. In the sealed position, the sealing piece 338 of the second valve core 330 is hermetically sealed against the upper section 312 of the third tube portion 254, as shown in Figure 20. The sealing piece 338 can produce a contact of line with the upper section 312 of the third tube portion 254 in the sealed position. In the open position, the sealing member 338 of the second valve core 330 is moved away from the upper section 312 of the third tube portion 254 until the lower abutment surface 336 of the head 334 abuts the locating stem 324. of the second valve support 320. Due to the line contact produced between the sealing piece 338 and the upper section 312 of the third tube portion 254 in the sealed position, the sealing piece 338 can freely separate from the upper section 312 of the third tube portion 254 without a sticking phenomenon, even if the second check valve 310 has not been used for some time, the service life of the second check valve 310 is increased.

When no air or water is present in the third tube portion 254, the second check valve 310 moves to the sealed position, in which the sealing piece 338 of the second valve core 330 is hermetically sealed against the upper section 312. of the third tube portion 254 by the effect of the second elastic spring 340. Because the upper section 312 of the third tube portion 254 narrows in an upward direction, the seal between the sealing piece 338 of the second valve core 330 and the upper section 312 of the third tube portion 254 becomes progressively tighter as the water pressure of the ^whirlpool 100 increases ^.

When the air pump 232 is on, the air reaches the second check valve 310 and forces the second valve core 330 down through the locating stem 324 of the second valve holder 320 to the open position, in which the sealing piece 338 is separated from the upper section 312 of the third tube portion 254 and the second elastic spring 340 is compressed. With the second check valve 310 in the open position, air flows through the valve stem. location 324 of the second valve support 320 and the ^whirlpool 100 ^.

As shown in Figure 40, the flexible connecting pipe 770 of the jet water pipe network 760 extends annularly around the whirlpool 100 from both outlets 736 of the outlet pipe 700.

The jet water pipe network 760 further includes a plurality of flexible sealing sleeves 772 for coupling each spray nozzle 762 to the inner wall 106 of the whirlpool 100 in a sealed manner to ^{prevent air and water leakage into the pool. whirlpool} 100 ^{and to prolong the service life of the whirlpool} 100. The inner wall 106 of the whirlpool 100 can be sandwiched between each sealing sleeve 772 and the corresponding spray nozzle 762 in a sealed manner, as shown in Fig. Figure 41. Each sealing sleeve 772 may have a stepped configuration that includes a small stem portion 774 and a large head portion 776 that forms a flange 778 around the sealing sleeve 772. The small stem portion 774 of each sealing sleeve seal 772 may be internally or externally coupled to the corresponding spray nozzle 762 using suitable coupling techniques, such as coupling high-frequency heating, hot coupling (p. g., melting or injection moulding), or adhesion (eg, gluing). The flange 778 on the large head portion 776 of each sealing sleeve 772 can be attached to the inner wall 106 of the whirlpool 100, also suitable attachment techniques. In accordance with the present disclosure, the material used to construct the sealing sleeves 772 may be the same as the material used to construct the inner wall 106 of the whirlpool 100, such as PVC, TPR, EVA, or TPU. Such materials may be fused to seal the sealing sleeve 772 to its adjacent components and may be capable of thermal expansion without cracking.

The jet water pipe network 760 further includes an air transport tube 780. The air transport tube 780 may be similar to the air transport tube 380 of Figures 23 and 24 described above. In the illustrated disclosure of Figures 39-40, air transport tube 780 extends through outer wall 108, through air chamber 110, and through inner wall 106 of whirlpool 100. Additional sealing sleeves 772 may be used to couple the air transport tube to the outer wall 108 and/or the inner wall 106 of the whirlpool 100 in a sealing manner.

The air transport tube 780 can directly direct air to the water cavity 112 of the whirlpool 100. The air transport tube 780 can also indirectly direct air to the water cavity 112 of the whirlpool 100 through spray nozzles 762. In the illustrated disclosure of Figures 39-40, air transport tube 780 draws air from the surrounding atmosphere, directs the air through a flexible annular connecting tube 782, and injects air into the air hole 768 of each spray nozzle 762 by the suction force of the water flow through the spray nozzle 762. The air from the air transport tube 780 mixes with the water in the spray nozzle 762. spray 762 to spray water in a jet stream into the water cavity 112 of the whirlpool 100. The flexible nature of the connecting tube 782 may allow the deflated whirlpool 100 to be collapsed to its core. dinner and / or transfer.

It is also within the scope of this disclosure that air transport tube 780 may communicate with an air pump (eg, air pump 232 of Figures 15-18), as noted above in the section "Aspect of the bubble". In this case, the air transport tube 780 can also supply massaging air bubbles to the whirlpool 100.

Returning to Figure 27, the controller (not shown) of the control system 500 can ensure that the electrical current of the control system 500 remains below a predetermined limit, such as a standard household limit of 13A to 16A. In one disclosure, the controller may limit the power supply to one or more control system units 500 when the jet water pump 534 is activated, and the controller may restore the power supply to the other control system units. control when the jet water pump 534 is off. For example, the controller may automatically limit the power supply to the heating unit (not shown) to approximately 50% or less when the jet water pump 534 is activated, and the controller may automatically restore the power supply. to the heating unit at 100% when the jet water pump 534 is deactivated. The controller can further limit the power supply to the heating unit to 0% when both the jet water pump 534 and an additional air pump are activated.

The invention has been described with reference to the aforementioned preferred embodiments, therefore, it cannot limit the reference implementation of the invention. It is obvious to a person skilled in the art that changes and modification in structure can be made without departing from the scope of the invention defined by the following claims.
