Description

Technical Field

[0001] The invention relates to the field of bathroom products, in particular to a shower kit. Background Art

[0002] With the development of technology, the functions of showers on the market are becoming more and more diverse. Some showers have both constant temperature water outlet and switch water outlet functions; the constant temperature water outlet and switch water outlet functions in the shower are realized by installing a constant temperature valve core and a switch valve core at both ends of the shower respectively; the constant temperature valve core can automatically adjust the mixing ratio of hot and cold water so that the temperature of the mixed water can be automatically maintained at the set temperature; the switch valve core can switch the shower to wall-mounted water outlet or handheld water outlet.

[0003] After the thermostatic valve core and the switching valve core in the shower are installed, since the positions of most hot water inlet pipes and cold water inlet pipes are fixed, if the user wants to swap the left and right positions of the thermostatic valve core and the switching valve core according to usage habits, it can only be achieved by rotating the entire shower 180 degrees; however, since most thermostatic valve cores have cold water on the left and hot water on the right, directly rotating the shower will cause hot water to enter the left side of the thermostatic valve core and cold water to enter the right side, which will make the thermostatic water outlet function of the thermostatic valve core invalid. Therefore, users cannot arbitrarily swap the position of the thermostatic module on the shower according to their usage habits. Summary of the invention
