Thereby, when the device 100 for adding a fluid medium to a shower system according to the embodiment of the present application is used by a user, a negative pressure is generated in the water inlet pipe 31a of the water jet pump 31 of the device of the present application, so as to control a fluid medium to be sucked from a fluid medium inlet 21a of the suction pipe 21 and flow into a water return pipe 31b of the water jet pump 31. The fluid medium is mixed with the water flowing into the water inlet pipe 31a of the water jet pump 31 in the water mixing pipe 31c of the water jet pump 31, and then flows into the shower system via the water outlet 11b to supply the fluid medium for the user. In the above operations, the fluid medium can be brought into contact the skin of the user without directly squeezing the bottle containing the fluid medium by hand.
In addition, the device 100 for adding a fluid medium to a shower system according to the embodiment of the present application can achieve at least some of the following effects.
Reliability is good. The device according to the embodiment of the present application is provided with a one-way valve 32 between the fluid medium inlet 21a and the fluid medium outlet 21b. Therefore, such device of the present application can prevent the fluid medium from flowing back and prevent water from flowing out of the fluid medium inlet 21a and in turn contaminating the fluid medium.
The versatility is good. The device according to the embodiment of the present application can be directly installed in the existing shower system, which can easily and quickly solve the cumbersome cleaning work of the user.
It is understood for those skilled in the art that the fluid medium used by people when showering includes perfume, soapy water, shampoo, shower gel or other skin care products in form of fluid.

The device according to the embodiment of the present application can also be integrated into a bathtub.
In some specific examples of the present application, the three-way valve pipe includes a venturi nozzle. The water inlet pipe 31a, the water return pipe 31b and the water mixing pipe 31c meet at a center (not shown), and the venturi nozzle is provided between the water inlet pipe 31a and the center. The venturi nozzle has a continuously reduced cross-sectional area of a flow channel, which can form a low pressure in the water inlet pipe 31a, thereby sucking the fluid medium transported and mixing it with water in the water mixing pipe 31c. The device according to the embodiments of the present application has a strong self-suction capability and can reliably suck the fluid medium into the water pipe 11.
In some specific examples of the present application, the three-way valve pipe is a venturi three-way valve pipe. The venturi three-way valve pipe has a venturi nozzle that continuously reduces a cross-sectional area of a flow channel and a venturi diffusion chamber that continuously increases the cross-sectional area of the flow channel (the venturi diffusion chamber is located between the center and the water outlet 11b). Therefore, the device according to the embodiments of the present application has a better self-suction capability. In addition, the venturi diffusion chamber is relatively insensitive to the impurities, and thus is especially suitable as a discharge pipe for the mixed liquid after the fluid medium is mixed with water.
In some specific examples of the present application, the fluid medium pipe assembly 20 includes a venturi switch 22, and the venturi switch 22 is provided between the fluid medium inlet 21a and the water return pipe 31b.
