DETAILED DESCRIPTION

The implementation and application of embodiments of a circulation and filtration system for a pool will be discussed in detail below. However, it should be understood that the embodiments discussed and illustrated herein illustratively described various embodiments, implementations, and applications of the present disclosure, and are not intended to limit the scope of the present disclosure.


Referring now to the drawings, FIG. 1 depicts a filtering and circulation system for a pool may include a skimming and drainage device, such as a skimmer 1, and a water flow driving device 2. In these embodiments, the pool may include a liner 3 and a frame 4, with the frame 4 being arranged outside the liner 3 and the liner 3 being connected to the frame 4, such that water may be contained in the frame 4 defined by the liner 3 to form the pool. In the embodiments described herein, the liner 3 may be formed of polyvinyl chloride (PVC), vinyl, reinforced polymer, thermoplastic polyurethane (TPU), rubber, or any other similar composite material capable of providing a desired durability for the pool.


Referring now to FIGS. 1-3, the skimmer 1 may be provided with an upper water inlet 38 and a lower water inlet 39. In these embodiments, the upper water inlet 38 may be positioned close to (e.g., proximate and/or adjacent to) a top surface of the pool, while the lower water inlet 39 may be positioned close to (e.g., proximate and/or adjacent to) a bottom surface of the pool. As depicted mostly clearly in FIG. 1, the water flow driving device 2 may deliver a water flow discharged from the skimmer 1 into the pool.


As further depicted in FIG. 1, a drainage pipe 5 may be coupled to the skimmer 1 and may be configured to channel water from the skimmer 1 to the water flow driving device 2 (and vice versa). In these embodiments, the drainage pipe 5 may further include a branch 6 that fluidly couples the drainage pipe 5 to each of the lower water inlet 39 and the upper water inlet 38. For example, the branch 6 may have end portions which extend to the bottom and/or top of the pool to couple with the lower water inlet 39 and the upper water inlet 38, respectively. It should be appreciated that by fluidly coupling the drainage pipe to each of the upper water inlet 38 and the lower water inlet 39 (e.g., via branch 6), it may be possible to ensure that water from both levels of the pool (e.g., a top surface adjacent the upper water inlet 38 and a bottom surface adjacent the lower water inlet 39) is filtered and circulated. In these embodiments, transporting water from the pool and through the water flow driving device (e.g., via the drainage pipe 5) may also ensure that debris and impurities are removed from the water entering the pool, as will be described in additional detail herein.


Referring again to FIGS. 1-3, the skimmer 1 may be mounted on the liner 3 close to (e.g., proximate and/or adjacent to) the water surface. In these embodiments, the liner 3 may be provided with a drain outlet corresponding to the skimmer 1, with the upper water inlet 38 being hermetically connected to the drain outlet formed in the liner 3. As illustrated most clearly in FIG. 2, an outlet end of the skimmer 1 may be connected to the drainage pipe 5, such that water is able to flow between the skimmer and the water flow driving device 2, as described hereinabove.


As further depicted in FIGS. 1-3 the skimmer 1 may further include a directional valve 7 mounted on the drainage pipe 5 at the location where the branch 6 is coupled to the drainage pipe 5. In these embodiments, the drainage pipe 5 and the branch 6 may both be connected to the directional valve 7, such that actuation of the directional valve alters the flow of water through the drainage pipe 5 and the branch 6, as will be described in additional detail herein.


As most clearly depicted in FIG. 3, the directional valve 7 may further include a valve flap 8, which may be configured to rotate to switch flow paths of the directional valve 7. For example, in these embodiments, the valve flap 8 is provided with a rotating shaft, which extends out of an outer wall of the directional valve 7 and is connected to a handle 9. Accordingly, the valve flap 8, and in turn, the directional valve 7, may be adjusted by rotating the handle 9 illustrated in FIG. 3


Referring now to FIGS. 2 and 3, the directional valve 7 may be provided with three openings, with a first opening, such as an upper opening, and a second opening, such as a lower opening, being connected to the drainage pipe 5 and a third opening, such as a central opening, being connected to the branch 6. In these embodiments, when the handle 9 is in a first position (e.g., in parallel with the central opening and branch 6, as depicted in FIG. 3), water may flow between the upper surface of the pool (e.g., at upper water inlet 38) and the drainage pipe 5, such that the water traverses the upper opening and the lower opening of the directional valve 7. When then handle 9 is moved to a second position (e.g., such that the handle 9 is parallel with the upper opening and lower opening of the directional valve 7), water may flow between the lower surface of the pool (e.g., at lower water inlet 39) and the drainage pipe 5, such that the water traverses the central opening and the bottom opening of the directional valve.


In the embodiments described herein, the valve flap 8 may further include a sealing surface, which may have an arc-shaped structure. Accordingly, the arc-shaped structure of the valve flap 8 may allow the valve flap 8 to rotate in order to close any one of the openings or to open and communicate all of the three openings of the directional valve 7, as described hereinabove.


Referring again to FIGS. 1-3, the skimmer 1 may further include a plurality of protective covers mounted at a lower portion of the skimmer 1, which may be connected together to form a mounting cavity. In these embodiments, the directional valve 7 may be arranged in the mounting cavity, while the handle 9 is exposed outside the mounting cavity, such that a user is able to access the handle 9 to adjust operation of the directional valve 7, as has been described herein.


Referring again to FIG. 3, the branch 6 of the directional valve 7 is depicted in additional detail. As depicted, the branch 6 may include an inner pipe 13 and an outer pipe 14, with a mounting head 15 and a steering head 16 being arranged between the inner pipe 13 and the outer pipe 14. In these embodiments, the liner 3 of the pool may be provided with a connecting hole 17, which may correspond with and be configured to receive the branch 6. In particular, as illustrated in FIG. 3, the mounting head 15 may be adapted to be received by the connecting hole 17 formed in the liner 3.


Referring still to FIG. 3, the steering head 16 of the branch 6 may be connected between the mounting head 15 and the inner pipe 13, with the mounting head 15 being connected (e.g., hermetically sealed) to the outer pipe 14. In these embodiments, the mounting head 15 may be provided with an outwardly protruding annular disk 18, and a sealing ring 19 may be mounted between the annular disk 18 and an inner wall of the liner 3. As shown in FIG. 3, the mounting head 15 may be in threaded connection with a locking ring 20, with the locking ring 20 being configured to abut against an outer wall of the liner 3.


As further illustrated in FIG. 3, the outer pipe 14 may further include a fastening ring 21 sleeved about (e.g., disposed about) the outer pipe 14. In these embodiments, the fastening ring 21 may be formed by assembling two semicircular connecting members, with the two semicircular connecting members being connected to each other by means of a T-shaped engagement structure. As further depicted in FIG. 3, an end portion of the outer pipe 14 may be provided with a flange 22, while the fastening ring 21 may be provided with a positioning projection 23, which may be configured to abut the flange 22. As depicted in FIG. 3, an end face of the outer pipe 14 may be coupled (e.g., hermetically sealed) to an end face of the mounting head 15. In these embodiments, the inner pipe 13 may be vertically arranged close to (e.g., proximate and/or adjacent to) the inner wall of the liner 3, and a lower end of the inner pipe 13 may be connected to a filter cover 24.


Referring again to FIGS. 1-3, it should be appreciated that the directional valve 7 is mounted below (e.g., beneath) the skimmer 1. Furthermore, in these embodiments, at least a portion of the drainage pipe 5 that extends between the directional valve 7 and the skimmer 1 may be formed of a corrugated pipe, which may facilitate adjusting a length of the drainage pipe 5 during mounting of the skimmer 1. To further aid in case of installation, the outer pipe 14 and the inner pipe 13 may be conveniently connected to the liner 3 by means of the mounting head 15 and the steering head 16.


Referring now to FIG. 1, it should be appreciated that, in some embodiments, the pool may further include a water curtain discharge device 10 mounted to the pool. In these embodiments, the pool may further include a water discharge pipe 11 mounted between the water curtain discharge device 10 and the water flow driving device 2, such that water is able to flow between the water curtain discharge device 10 and the water flow driving device 2.


As further depicted in FIG. 1, the water curtain discharge device 10 may be provided with a strip-shaped water outlet, such that the water delivered to the water curtain discharge device 10 from the water flow driving device 2 is discharged from the water outlet to form a water curtain that falls into the pool. In these embodiments, a mood lamp 12 may be mounted on the water curtain discharge device 10, which may be mounted on top of a frame of the pool. Embodiments of the water curtain discharge device 10 will be described in additional detail herein with reference to FIGS. 15-21. Referring again to FIGS. 1-3, operation of the skimmer 1 and the water flow driving device 2 will now be described in additional detail. For example, when the water flow driving device 2 is activated, floating objects on the water surface of the pool and/or on the bottom surface of the pool may enter the water flow driving device 2 after flowing into the skimmer 1. In these embodiments, water at the bottom of the pool may be pumped into the water flow driving device 2 through the branch 6, and the water may be delivered into the pool after being filtered by the water flow driving device 2, so as to generate filtering and circulation of the water. Furthermore, by rotating the handle 9, as described in detail hereinabove, the flow paths of the directional valve 7 may be changed, thereby alternating the directional valve 7 between a plurality of filtering modes. For example, in various filtering modes of the plurality of filtering modes, the directional valve may be configured to allow for the filtering of only the floating objects at the water surface of the pool, filtering only of water at the bottom of the pool, or filtering of water at both the water surface and the bottom of the pool, It should be further appreciated that, in the embodiments described herein, the water flow discharged from the water flow driving device 2 may be delivered to the water curtain discharge device 10, at which point the water may be discharged outwardly through the strip-shaped water outlet on the water curtain discharge device 10 to form a water curtain. The mood lamp 12 may then be turned on while the water curtain is formed, so as to increase the ornamental value of the pool.


Turning now to FIGS. 4-6, another embodiment of a pool having a skimmer 1 and a water flow driving device 2 is depicted. It should be appreciated that the skimmer 1 and the water flow driving device 2 depicted in FIGS. 4-6 are similar to those described with reference to FIGS. 1-3. Accordingly, like structure is indicated with like reference numerals where possible.


In the embodiments depicted in FIGS. 4-6, the pool may further include a water supply connector 25 mounted on the liner 3 of the pool and a water discharge pipe 11 mounted between the water supply connector 25 and the water flow driving device 2. In these embodiments, the water supply connector 25 may include a connector body 26 and an inner end cover 27. A threaded sleeve 28 may be mounted between the connector body 26 and the inner end cover 27. A raised ring 29 may be arranged on an outer wall of the threaded sleeve 28.


As depicted most clearly in FIG. 4, the liner 3 of the pool may be provided with a mounting hole 30, which may correspond to and be configured to receive the water supply connector 25. In particular, the threaded sleeve 28 of the water supply connector 25 may be adapted to be received by the mounting hole 30. In these embodiments, when the water supply connector engages the mounting hole 30, the raised ring 29 is sealed against the inner wall of the liner 3 of the pool. Accordingly, the seal formed between the raised ring 29 and the liner 3 of the pool may ensure that water is not able to flow between the water supply connector 25 and the water flow driving device 2 without leaking.


Furthermore, when the water supply connector 25 is engaged with the pool liner 3, the threaded sleeve 28 may engage in threaded connection with a fastening sleeve 31. In these embodiments, the fastening sleeve 31 may be attached (e.g., hermetically sealed) to an outer wall of the liner 3 of the pool. As further depicted in FIGS. 4-6, in these embodiments, the inner end cover 27 of the water supply connector 25 may be connected to an inner end of the threaded sleeve 28, while the connector body 26 may be connected to an outer end of the threaded sleeve 28.


As further illustrated most clearly in FIG. 6, the connector body 26 may be provided with a connecting pipe 32, and an end portion of the connecting pipe 32 may be provided with a ledge 33. A threaded fixing sleeve 34 is disposed about (e.g., sleeved about) the connecting pipe 32, and the end portion of the connecting pipe 32 is coupled (e.g., hermetically sealed) to the outer end of the threaded sleeve 28. As depicted in FIG. 6, the threaded fixing sleeve 34 is in threaded connection with the threaded sleeve 28 and is further provided with an abutment projection 35 that abuts against the ledge 33. A sealing gasket 36 is mounted between the raised ring 29 and the inner wall of the liner 3. The inner end cover 27 is provided with an outwardly-extending insertion sleeve 37, the insertion sleeve 37 is adaptively inserted into the threaded sleeve 28, the inner end cover 27 is provided with a mesh, and the inner end cover 27 and the threaded sleeve 28 are in threaded connection with each other.


In some embodiments, it should be further understood that the connecting pipe 32 and the connector body 26 may be connected together to form a T-shaped structure, and the fastening sleeve 31 and the raised ring 29 may be placed on each side (e.g., an inner side and an outer side) of the liner 3, thereby forming tight connection between the threaded sleeve 28 and the liner 3. In these embodiments, an outer edge of the raised ring 29 may be provided with an inwardly-protruding connecting ring, an outer wall of the connecting ring may be provided with threads, and the inner end cover 27 may be fastened to the connecting ring by means of threaded connection.


Referring again to FIGS. 4-6, it should be appreciated that, in these embodiments, the skimmer 1 may be mounted at an upper portion of the liner 3 of the pool, and the branch 6 may be connected to the middle of the liner 3. A lower end of the skimmer 1 may be connected to the water flow driving device 2 via the drainage pipe 5. The water supply connector 25 may be mounted at an upper middle position of the liner 3 (e.g., as illustrated in FIG. 4), and the water discharge pipe 11 may be connected between the water flow driving device 2 and the water supply connector 25. It should be appreciated that, in these embodiments, the water supply connector 25 facilitates the connection between the water discharge pipe 11 and the liner 3, and thus facilitates circular flow of the water into the pool.


Referring still to FIGS. 4-6, operation of the water flow driving device 2 and the water supply connector 25 will be described in additional detail. For example, and as described hereinabove with reference to FIGS. 1-3, once the water flow driving device 2 is activated, floating objects on the water surface of the pool and/or on the bottom surface of the pool may enter the water flow driving device 2 after flowing into the skimmer 1. In these embodiments, water at the bottom of the pool may be pumped into the water flow driving device 2 through the branch 6, and the water may be delivered into the pool after being filtered by the water flow driving device 2, so as to generate filtering and circulation of the water. Furthermore, by rotating the handle 9, as described in detail hereinabove, the flow paths of the directional valve 7 may be changed, thereby alternating the directional valve 7 between a plurality of filtering modes. For example, in various filtering modes of the plurality of filtering modes, the directional valve may be configured to allow for the filtering of only the floating objects at the water surface of the pool, filtering only of water at the bottom of the pool, or filtering of water at both the water surface and the bottom of the pool. The water flow discharged from the water flow driving device 2 may then be discharged into the pool by means of the water supply connector 25 to complete filtering and circulation.


Turning now to FIGS. 7-14, embodiments of a pool skimmer connection structure for coupling the skimmer 1 to the pool (e.g., the liner 3 of the pool) are depicted. It should be appreciated that each of the embodiments of the pool skimmer connection structure described herein may be used in connection with the skimmer 1, pool, and circulation and filtration systems described with reference to FIGS. 1-6. Accordingly, like structure will be indicated with like reference numerals when possible.


Referring now to FIGS. 7-9, in some embodiments, the skimmer 1 may include a pool skimmer connection structure configured to couple the skimmer 1 to the liner 3 of the pool, as has been described hereinabove. In these embodiments, the pool skimmer connection structure may include a skimmer body 100, a skimmer drainage tube 102 provided on and/or coupled to the skimmer body 100, and a baffle 103 mounted within the skimmer drainage tube 102 proximate and/or adjacent to an opening. In these embodiments, a lower portion of the baffle 103 may be rotatably mounted to an inner wall of the skimmer drainage tube 102, such that the baffle 103 may be rotated within the skimmer drainage tube 102 to adjust water flow through and/or within the skimmer. For example, when the skimmer 1 is in operation, the baffle 103 may be rotated to an open position, such that water is able to flow through the skimmer drainage tube 102. In contrast, when the skimmer is deactivated, the baffle 103 may be rotated to a closed position, such that water is unable to flow through the skimmer drainage tube 102. In these embodiments, it should be appreciated that water may remain in the skimmer drainage tube 102 when the skimmer initially ceases operation. At this time, the baffle 103 may become vertically positioned on a water surface under the action of buoyancy to block floating objects from traversing the skimmer drainage tube 102.


Referring still to FIGS. 7-9, the pool skimmer connection structure may further include a fastening sleeve 110 connected to the liner 3, and a connector 111 may be provided on the fastening sleeve 110. In these embodiments, the connector 111 may extend outwardly through the liner 3 to the outside of a pool (e.g., extending through the liner 3).
