The integrated waterway module 2 supports the fixed booster pump 3 through the pump bracket 31 at the bottom, thereby avoiding the direct pressure of the booster pump 3 directly on the integrated waterway module 2, resulting in insufficient welding of the integrated waterway plate and the integrated waterway body, and water seepage The problem.

A plurality of bottom brackets 26 may be integrally formed or assembled outside the integrated waterway module 2 to support the respective filter elements in the filter cartridge group 4, respectively. At least one buckle for fixing the external circuit is installed outside the integrated waterway module, and the buckle form may be a C-clip or other existing cable organizer to regulate various power lines and signal lines in the water purification equipment.

In the integrated waterway module, at least two flow channels are respectively located on different planes, wherein the extending direction of the flow channel in one plane intersects with the extending direction of the flow channel on the other plane, and the flow direction of the inner mold is between the flow paths. Interlaced on each other. This structure is inconvenient for direct injection molding in the injection molding process because it is inconvenient to mold. The integrated water channel module 2 has such a structure that the inner cavity flow path intersects, one implementation method is block injection molding, and the other implementation mode is 3D printing molding, wire material selective cladding molding, photosensitive resin selective curing molding. Rapid prototyping methods such as selective sintering of powder materials or solid lamination of foil laminates can of course be made by combining injection molding and machining.

In FIG. 3A, the integrated waterway module 2 in the present embodiment can be generally square, and the outer side of the integrated waterway module 2 is six interface interfaces 2A. In other embodiments, the integrated waterway module 2 can also be selected as other polyhedrons, and the number of interface interfaces 2A is not limited.

In FIG. 3A, the integrated waterway module 2 includes a body 22, a lower cover 23 and an upper cover 24. The lower cover 23 and the upper cover 24 are respectively attached to the upper and lower surfaces of the body 22, and may be adjacent to each other. On the surface, such as the side and top, of course, more covers can be used. In this embodiment, the body 22 and the lower cover 23 and the upper cover 24 are sealingly fixedly connected in one body.

A plurality of flow paths 21 may be integrally formed in the integrated waterway module 2 to facilitate the sequential communication of the components. Each interface interface 2A is formed with a plurality of interfaces 25, each of which may include an access or take-off interface of the control valve, the booster pump 3 or the filter cartridge 4. The interface of the control valve, booster pump 3 or filter cartridge 4 is divided into a water inlet and a water outlet. The plurality of flow paths 21 are respectively connected to the respective interfaces in the order required by the design.

As shown in FIG. 3A, the integrated waterway module 2 has two waterway layers 210 and a connection zone 220. The waterway layer 210 has a plurality of flow channels 21 therein, and the plurality of flow channels 21 in the waterway layer extend in the same plane. The connecting region 220 has a plurality of flow channels 21, and the extending direction of each of the flow channels 21 in the connecting region may be perpendicular or obliquely intersecting with the planar direction of the waterway layer 210. In the embodiment, vertical intersecting is taken as an example. Each of the flow passages 21 in the connection region 220 communicates with each of the interfaces 25 and the flow passages 21 in the water passage layer 210.

As shown in FIG. 3A and FIG. 3C, the connection area 220 is located between the two waterway layers 210, and each flow channel 21 in the connection area 220 is divided into two. Do not connect at least the top 21 of each waterway layer. Moreover, each of the flow channels in the connecting region 220 has the same extending direction, and the extending direction may be the same as the direction of the mold-removing after the injection molding, so as to facilitate the parting. At least one end of each flow channel 21 in the connection zone 220 is connected to the first-class track 21 in the waterway layer to facilitate the push-in and exit of the molding die.

Two waterway layers 210 are respectively located between the lower cover 23 and the body 22, and between the upper cover 24 and the body 22. In this way, the groove shape of the two waterway layers 210 can be respectively formed on the body 22 or the lower and

upper covers

23 and 24, and then the body 22 and the lower cover 23 and the upper cover 24 are sealed and connected to form a complete waterway. Layer 210. The body 22, the lower cover 23 and the upper cover 24 can be respectively injection molded, and then the three are fixedly coupled together. The body and the cover may be ultrasonically welded, may be glued, may be snap-fitted, or may be connected by fasteners such as bolts.

Thus, since the water channel layer 210 in which the plurality of flow paths are horizontally arranged is formed on the open end surface of the body 22, the molding core does not protrude into the interior. The cores forming the multiple flow paths in the connection region 220 are pointed inwardly in the same direction, and no interference occurs. The utility model can solve the problem that the multi-layer inner cavity waterway cannot be normally divided during injection molding, and the injection mold of the main body 22 can adopt upper and lower split molds, or can adopt upper, lower, left and right multi-directional split molds, and the inner molding core does not. Will be stuck.

In this embodiment, a plurality of grooves (positions indicated by reference numeral 21) may be respectively formed in the body 22 to form a plurality of flow paths, and a plurality of grooves may be formed in the cover body to form a plurality of flow paths. The body 22 and the

cover bodies

231, 241 may be formed by injection molding, of course, other materials and molding means may be selected, such as a light metal material formed by machining means such as extrusion, molding, opening, or the like; or a non-metal material is integrally formed. It is produced by rapid prototyping such as 3D printing molding, selective coating of filament materials, selective curing of photosensitive resin, selective sintering of powder materials or solid formation of foil laminates. In the embodiment, the main body 22 and the

cover bodies

231 and 241 are respectively injection-molded, and the molding method has the advantage of the fusion sealing effect, and the pressure resistance of the overall product is ensured.

covers

231, 241 can collectively enclose a part of the flow paths of the plurality of flow paths. 3A-3C, the lower cover 23 and the upper cover 24 are respectively attached to the opposite upper and lower surfaces of the body 22. The opposite upper and lower surfaces of the body 22 have open ends due to the respective grooves. A water channel layer 210 in which a plurality of flow channels are horizontally arranged is formed on an open end surface of the body 22.

The body 22 is formed with a closed peripheral wall 221 and a plurality of inner groove walls 222. The peripheral wall 221 and the groove wall 222 are both part of the body 22, and the body 22 is a single piece. To form a plurality of flow paths 21 of the body 22, a peripheral wall 221 and a groove wall 222 are formed.

Referring to FIGS. 4-6, the peripheral wall 221 is substantially the outer wall surface of the body 22. Since some areas of the body 22 are shaped to be concave or convex for the arrangement of the external functional components, the concave portion 224 or the convex portion is formed. Out part (not in the picture) Shown), the corresponding peripheral wall 221 will also have a concave or convex portion. The surface of the peripheral wall 221 that meets the

cover bodies

231 and 241 is an outer joint end surface 2211. The inner side of the outer joint end surface 2211 can be engaged with the

cover bodies

231 and 241, and the outer side of the outer joint end surface 2211 can be combined with the injection

molding rubber structures

232 and 242. . An outer groove 2212 may be formed on the outer side of the outer joint end surface 2211, and the outer side groove 2212 may be a wedge-shaped groove extending inward from the bottom of the groove, so that the rubber-clad

structure

232, 242 is formed into a wedge-shaped reinforcing structure with the peripheral wall 221.

Each groove wall 222 has a height direction substantially perpendicular to the

cover bodies

231 and 241, and each groove wall 222 respectively divides a plurality of flow channels in the peripheral wall; and each groove wall 222 facing the joint end of the body 22 is generally combined with the body-facing body 22 The individual groove walls 222 of the ends are different. This is determined according to the arrangement of the multiple flow paths 21 in the upper and lower water channel layers 210. Each of the groove walls 222 is a part of the body, and is also connected to each other. In fact, each groove wall 222 can also be regarded as a whole, but extends to different positions. Each of the groove walls 222 is formed with an inner joint end surface 2221 on the open surface or the lower open surface of the body 22. The inner joint end surface 2221 of each groove wall 222 on the open surface or the lower open surface of the body 22 is substantially flush.

The central portion of the inner end surface 2221 can form a coupling groove 2222 or a coupling protrusion 2223, so that the rubber-clad

structures

232, 242 form a convex-concave joint structure. As shown in FIG. 4, in an embodiment, the coupling groove 2222 is a trapezoidal groove having a small outer side and a small inner side to facilitate outward ejection. As shown in FIG. 5, the coupling convex portion 2223 may be a trapezoidal convex portion having a small outer side and a small inner side. And the coupling groove 2222 or the coupling protrusion 2223 of the inner joint end surface 2221 may be formed with a reinforcing hole 2224 or a reinforcing protrusion (not shown), so that the

rubber covering structures

232, 242 form a convex-concave reinforcing structure.

In this way, the outer joint end surface 2211 can have an injection molding rubber structure, and the inner joint end surface 2221 also has an injection molding rubber structure.

For example, referring to the embodiment of the upper cover 24 shown in FIG. 4 and FIG. 5, the upper cover 24 is composed of a cover body 241 and an encapsulation structure 242. The cover body 241 is a primary molded piece, and the cover structure 242 is secondary. The molded part is molded, and the upper cover 24 and the body 22 are integrated into one body by the overmolding molding 242. The cover body 241 forms a flow path groove 2418 corresponding to each flow path 21 of the adjacent water channel layer 210, and the flow path groove 2418 is used to constitute the flow path 21. The width at each flow channel groove 2418 is slightly smaller than the width of the flow channel 21 in the corresponding body 22. Thus, the cover body 241 corresponds to the inner joint end surface 2221 of the groove wall 222 but forms a boss 2410. The width of the boss 2410 is larger than the width of the inner joint end surface 2221, and the groove 2419 capable of accommodating the inner joint end surface 2221 is formed in the boss 2410. In order to engage the inner joint end surface 2221 in the lid body 241, the joint sealing property is protected, and the pressure resistance is improved. The above structure allows the inner joint end surface 2221 and the cover body and the joint surface to be located on the side of the flow passage 21 and located in the pocket 2419 to reduce the shearing force of the water pressure in the flow passage 21 on the joint surface.

As shown in FIG. 4 and FIG. 5 , the outer peripheral surface of the cover body 241 is a rubber-bonding joint surface 2412 , and the rubber-bonding joint surface 2412 is contracted away from the outer surface of the peripheral wall 221 by a distance smaller than the thickness of the peripheral wall 221 . Thereby, the rubber-bonding surface 2412 is snapped onto the outer joint end surface 2211. The outer outer covering rubber 2421 covers the rubberized bonding surface 2412 and the outer bonding end surface 2211 to seal the two.

The cover body 241 can be provided with a plurality of glue grooves 2411. The glue grooves 2411 can communicate with the rubber-bonding surface 2412. One is to facilitate the injection of glue, and the second is to form the outer rubber 2421 and the inner rubber 2422 continuously. The encapsulation structure 242. As shown in FIGS. 4 and 5, the glue tank 2411 has an outer opening 2413 and an inner opening 2417. External opening 2413 The inner opening 2417 is aligned with the inner joint end surface 2221, and the inner opening 2417 of the glue groove 2411 has a width smaller than the width of the inner joint end surface 2221. The inner opening 2417 of the glue groove 2411 is located in the receiving groove 2419 of the cover body 241. The injection molding encapsulation structure 242 is formed in the glue groove 2411, and the inner bonding end surface 2221 is sealedly connected to the cover body 241 through the injection molding rubber structure 242.

For example, the inner opening 2417 of the glue groove 2411 can be aligned with the middle portion of the inner end surface 2221 to seal the inner joint end surface 2221 with the cover body 241 through the injection molding structure 242 formed in the glue groove 2411 to prevent the second time. The hot glue in the injection mold melts the cover 241 and is flushed into the flow path 21.
