The diverter body is arranged in the installation cavity of the shell, which will not affect the installation of the water divider. The utility model can be installed in or outside the pipe fitting, and has strong practicality and a wide range of applications."

[0005] Including the solution described in the above patent, there is a problem with the water dividers (water dividers) in the prior art, that is, the number of water outlet pipes of the existing water dividers is fixed, and users need to purchase the water dividers according to the number of water outlet pipes they need before installation; and when the water divider is installed, if you want to add a water outlet pipe, you need to remove the original water divider and replace it with a new one with more water outlet pipes to meet the demand, which will result in the existing water divider If you want to add pipes, it is not only very inconvenient but also very costly. Summary of the invention

[0006] In order to overcome the disadvantage in the prior art that the number of water outlet pipes of the water distributor is fixed, and the water distributor must be disassembled and replaced if more water outlet pipes are desired after the water distributor is installed, the utility model provides a modular cold and hot water system water distributor.

[0007] The utility model solves the technical problem by providing a modular cold and hot water system water distributor, comprising:
