Device for adding fluid medium to shower system, and shower system

A shower system, comprising a showerhead and a water source connector for introducing water, wherein a water inlet of the showerhead is in communication with a water outlet of the water source connector, wherein the shower system further comprises a device for adding a fluid medium to the shower system, wherein the device comprises:

• a water pipe assembly comprising a water pipe, wherein the water pipe is provided with a water inlet and a water outlet, and the water inlet and the water outlet are configured to be connected with the shower system;
• a reservoir for storing the fluid medium, wherein the reservoir comprising a first chamber and a second chamber which are separate from each other, the first chamber is configured to accommodate a first fluid medium, and the second chamber is configured to accommodate a second fluid medium different from the first fluid medium;
• a fluid medium pipe assembly comprising a suction pipe and a switch valve, wherein the suction pipe is provided with a fluid medium inlet and a fluid medium outlet, and the fluid medium outlet is connected with the water pipe assembly, wherein the suction pipe comprises a communication portion, a first suction portion and a second suction portion, wherein a first end of the first suction portion extends into the first chamber, and a second end of the first suction portion is connected with a liquid inlet end of the communication portion, wherein a first end of the second suction portion extends into the second chamber, and a second end of the second suction portion is connected with the liquid inlet end of the communication portion, wherein the first end of the first suction portion and the second end of the second suction portion form the fluid medium inlet, and a liquid outlet end of the communication portion forms the fluid medium outlet, wherein the switch valve is configured to allow the communication portion to be selectively in communication with the first suction portion or the second suction portion;
• a valve body assembly comprising a first water pump and a three-way valve pipe, wherein the water inlet is in communication with a water inlet pipe of the three-way valve pipe through the first water pump, a water return pipe of the three-way valve pipe is in communication with the fluid medium outlet, and a water mixing pipe of the three-way valve pipe is in communication with the water outlet,
• wherein the water pipe assembly further comprises a bypass pipe and a flow regulator, wherein a water inlet end of the bypass pipe is in communication with the water inlet and the water inlet pipe, and a water outlet end of the bypass pipe is in communication with the water outlet and the water mixing pipe, wherein the flow regulator is provided between the water inlet end of the bypass pipe and the water outlet end of the bypass pipe,
• wherein the water outlet of the water source connector is further in communication with the water inlet of the water pipe, and the water inlet of the showerhead is further in communication with the water outlet of the water pipe.
