It is mainly used in floor heating systems, air conditioning water systems and tap water supply systems. At present, water distributors mainly include metal water distributors and plastic water distributors. Among them, metal water distributors are usually formed in one piece by a mold according to the number of water distribution pipelines, so multiple sets of different molding molds are required, the cost is high, and the versatility between metal water distributors with different numbers of pipelines is poor. Plastic water distributors include integrated plastic water distributors and spliced ​​plastic water distributors. The integrated plastic water distributor is also made into a variety of specifications according to the number of water distribution pipelines, and the cost is low, but the integrated plastic water distributor still has the defect of poor versatility. The spliced ​​plastic water distributor is formed by splicing two adjacent splicing pieces with a locking block. Specifically, the two ends of the splicing piece are respectively provided with protrusions. After the ends of the two splicing pieces are fitted, the locking block and the protrusions of the two splicing pieces are fastened through an interference fit relationship, so that at least two splicing pieces are spliced ​​in sequence to form a water distribution pipe. However, the assembly process of the spliced ​​plastic water distributor is relatively complicated, which makes disassembly and assembly difficult and the assembly efficiency is low. In addition, most of the existing spliced ​​water distributors are single-channel, which are only used for the distribution / collection of cold water or hot water.

[0067] Specifically, the water distribution assembly includes at least two first splicing pieces 1 spliced ​​in sequence. For example, the number of first splicing pieces 1 can be two, three, or four, etc. The specific number is adaptively selected according to the number of branches for water distribution / collection. Figure 5 , Figure 6 The first splicing piece 1 has a first channel 11 and a second channel 12 respectively running through its two ends, the first channel 11 and the second channel 12 are independent of each other and not connected, the first splicing piece 1 is provided with a first water diversion nozzle 13 connected to the first channel 11 and a second water diversion nozzle 14 connected to the second channel 12 on the outside, and the outer peripheral walls of the first water diversion nozzle 13 and the second water diversion nozzle 14 are provided with external threads or internal threads, and are connected to the hot water pipe and the cold water pipe respectively by threaded connection. In order to facilitate the description of the waterway layout of the present invention, the first water diversion nozzle 13 is set to be used for connecting the hot water pipe, and the second water diversion nozzle 14 is set to be used for connecting the cold water pipe in the embodiment of the present invention.

[0068] For further information, please refer to Figure 3 , Figure 8The first channels 11 of at least two first splicing pieces 1 are connected in sequence to form a first water diversion waterway 15, so that hot water is diverted to a plurality of first water diversion nozzles 13 through the first water diversion water pipe (or hot water is collected to the first water diversion water pipe through a plurality of first water diversion nozzles 13), and the second channels 12 of at least two first splicing pieces 1 are connected in sequence to form a second water diversion waterway 16, so that cold water is diverted to a plurality of second water diversion nozzles 14 through the second water diversion water pipe (or cold water is collected to the second water diversion water pipe through a plurality of second water diversion nozzles 14). A sealing membrane 40 is provided in the first water diversion waterway 15 or the second water diversion waterway 16, and the sealing membrane 40 has water-blocking sealing properties to prevent heat / water from passing through, such as a metal plate or a plastic plate. The sealing membrane 40 can be fixed to one end opening of the first channel 11 or the second channel 12 of one of the first splicing pieces 1 by means of sealant or the like to block the first water diversion waterway 15 or the second water diversion waterway 16. As some embodiments, when the number of cold water distribution / collection branches is required to be greater than the number of hot water distribution / collection branches, the sealing diaphragm 40 can be arranged in the first water diversion channel 15, for example, at an opening at one end of the first channel 11 close to the second splicing piece 2, so that the number of cold water distribution / collection branches is two more than the number of hot water distribution / collection branches.

[0069] Please refer to Fig. 9 - Fig.11 The second splicing piece 2 has two third channels 21 respectively penetrating its two ends. Specifically, the first ends of the two third channels 21 are connected in parallel and then penetrate one end of the second splicing piece 2, and the second ends of the two third channels 21 are respectively connected to the first water diversion channel 15 and the second water diversion channel 16, so that cold water can flow in from the first end of the third channel 21 and then flow out from the second ends of the two third channels 21 separately.

[0070] Please refer to Fig.12 - Fig.14 The third splicing piece 3 has two fourth channels 31 respectively penetrating through two ends thereof, and the two fourth channels 31 are separate and independent and not connected to each other.

[0071] Among them, please refer to Figure 1 - Fig.14, the second splicing piece 2, the water diversion assembly and the third splicing piece 3 are spliced ​​in sequence, one of the third channels 21, the first water diversion waterway 15 and one of the fourth channels 31 are connected in sequence, and another third channel 21, the second water diversion waterway 16 and another fourth channel 31 are connected in sequence. In this way, cold water flows in from the first end of the third channel 21 and is diverted from the second water diversion waterway 16 and the second water diversion nozzle 14, and the first channel 11 and the first water diversion nozzle 13 of the first splicing piece 1 located near the second splicing piece 2, and then the cold water flows along the second water diversion water flow and the fourth channel 31 into the heating device (such as a water heater, etc.) to be heated to form hot water, and finally the hot water flows from another fourth channel 31 into the first water diversion waterway 15 and is diverted through multiple first water diversion nozzles 13. In this way, the number of branches for cold water is more than the number of branches for hot water, which meets the use needs of different users.

[0072] For further information, please refer to Figure 1 - Figure 3 , Figure 5 , Figure 8 , Fig.15 , Fig.16 The first lock buckle 4 is provided with a first card slot 41, and the opposite ends of the first card slot 41 respectively penetrate the opposite sides of the first lock buckle 4. The second lock buckle 5 is provided with a second card slot, and the opposite ends of the second card slot respectively penetrate the opposite sides of the second lock buckle 5. The third lock buckle 6 is provided with a third card slot, and the opposite ends of the third card slot respectively penetrate the opposite sides of the third lock buckle 6. A first locking boss 7 that cooperates with and locks with the first card slot 41 is formed between the outer side walls of any two adjacent first splicing pieces 1, a second locking boss 8 that cooperates with and locks with the second card slot is formed between the outer side wall of the first splicing piece 1 and the outer side wall of the second splicing piece 2, and a third locking boss 9 that cooperates with and locks with the second card slot is formed between the outer side wall of the first splicing piece 1 and the outer side wall of the third splicing piece 3. Among them, in order to improve the assembly versatility of the parts, the structures and sizes of the first lock buckle 4, the second lock buckle 5 and the third lock buckle 6 are exactly the same, that is, the structures and sizes of the first locking boss 7, the second locking boss 8 and the third locking boss 9 are also exactly the same, so as to improve the assembly efficiency. At the same time, the number of the first locking bosses 7 between any two adjacent first splicing pieces 1 can be two, and the two are axially symmetrically arranged at the top and the bottom to improve the fastening effect. Correspondingly, the number of the second locking bosses 8 and the third locking bosses 9 can be two respectively, and the two second locking bosses 8 are axially symmetrically arranged at the top and the bottom, and the two third locking bosses 9 are axially symmetrically arranged at the top and the bottom to improve the fastening effect.

[0073] Please refer to Fig.15 , Fig.16As a specific implementation method in which the first slot 41 and the first locking boss 7 are mutually clamped, the second slot and the second locking boss 8 are mutually clamped, and the third slot and the third locking boss 9 are mutually clamped, the first slot 41 is a dovetail slot, the first locking boss 7 is in the shape of a dovetail, and the cross-sectional area of ​​the first slot 41 gradually decreases from one end to the other end; the second slot is a dovetail slot, the second locking boss 8 is in the shape of a dovetail, and the cross-sectional area of ​​the second slot gradually decreases from one end to the other end; the third slot is a dovetail slot, the third locking boss 9 is in the shape of a dovetail, and the cross-sectional area of ​​the third slot gradually decreases from one end to the other end. Among them, the first lock buckle 4, the second lock buckle 5 and the second lock buckle 5 may not have elasticity, such as hard plastic; or they may have a certain elasticity, such as elastic plastic. When the first lock buckle 4 is assembled on the first locking boss 7, the larger end of the opening of the first slot 41 is first inserted into the first locking boss 7, and the first lock buckle 4 is pushed to slide so that the first locking boss 7 gradually slides toward the smaller end of the opening of the first slot 41. During the process, the first lock buckle 4 and the first locking boss 7 are gradually tightened by interference fit, thereby completing the mutual locking of the first lock buckle 4 and the first locking boss 7. The first locking boss 7 is composed of a first sub-section 71 and a second sub-section 72, wherein the first sub-section 71 is located on the outer side wall of one end of the first splicing piece 1, and the second sub-section 72 is located on the outer side wall of the other end of the first splicing piece 1. When the two first splicing pieces 1 are spliced ​​with each other, the first sub-section of one first splicing piece 1 and the second sub-section of the other first splicing piece 1 are spliced ​​with each other to form a first locking boss 7 in the shape of a dovetail. In order to further distinguish the positions of the first sub-section 71 and the second sub-section 72 on the first splicing piece 1, the first sub-section 71 and the second sub-section 72 can be made to have different widths, so as to distinguish the assembly positions by size and improve the assembly efficiency.
