The utility model relates to a shower faucet, which has the following working principle:

pressurizing waterway principle: as shown in fig. 4 and 6, after any one or several waterway keys 13 are pressed, hot water and cold water respectively enter the thermostatic valve core 2 from the cold water inlet 11 and the hot water inlet 12 and are mixed to become mixed water, and the mixed water flows into the water diversion valve 3 after passing through the first electromagnetic valve 6 and the booster pump 4, enters the corresponding water diversion valve core 31 and flows out from the corresponding water diversion waterway. At this time, if the water pressure is low, the pressurizing button 14 is clicked, the pressurizing pump 4 is started to pressurize the water flow, so that the water pressure and the water flow of each water diversion waterway are obviously increased, the shower experience is improved, and meanwhile, the first electromagnetic valve 6 can protect the pressurizing pump 4 from being impacted by the excessive water pressure; when the water pressure is higher, the booster pump 4 can be not started, so that normal water supply can be realized.

Principle of cold water reflux: as shown in fig. 5 and 7, when the water path button 13 is pressed, the pressurizing button 14 is first double-clicked, at this time, the second electromagnetic valve 5 is opened, the pressurizing pump 4 is started, water flows from the hot water inlet 12 through the thermostatic valve core 2, flows to the first electromagnetic valve 6 after passing through the temperature sensing probe, then flows to the pressurizing pump 4, and flows back to the cold water inlet 11 after passing through the first electromagnetic valve 5 after being pressurized by the pressurizing pump 4. The water pressure at the hot water end is higher than the water pressure at the cold water end due to the pressurizing action of the booster pump 4, so that water flows from the hot water inlet 12 to the cold water inlet 11, flows back into the tap water pipe, and flows to the water heater along the tap water pipe. When the temperature sensing probe senses that the temperature is more than or equal to 38 ℃, the booster pump 4 stops working, the second electromagnetic valve 5 is closed, and at the moment, cold water at the hot water end is replaced by hot water flowing out of the water heater. At this time, when the waterway key 13 is pressed, the discharged water is hot water or warm water, so that the user is free from contacting with the cold water, and the cold water does not need to be discharged in advance.

The shower faucet has three functions of pressurizing, cold water backflow and common shower, can solve the two problems of small water pressure and cold water at the beginning of shower when in shower bath in the market, does not increase manufacturing cost while realizing the three functions, and can better meet the demands of users.
