In another embodiment: referring to fig. 13 to 18, the base case 110b of the water flow switching assembly 100b is shaped like a cylinder with a hollow interior, a first fluid channel 113b and a second fluid channel 114b are formed in the base case 110b, and the first fluid channel 113b and the second fluid channel 114b both extend along the axial direction of the base case 110 b. The first fluid channel 113b is used to conduct the first liquid, and the second fluid channel 114b is used to introduce the second liquid and to discharge the third liquid. The base cartridge 110b is also formed inside with a chamber 115b communicating with the second fluid passage 114b and for inputting functional water into the second fluid passage 114b, so that the second liquid in the second fluid passage 114b is mixed with the functional water to form a third liquid. In the present invention, the first liquid is raw water, the second liquid is a mixed water of filtered water and functional water, and the functional water is a liquid containing a cosmetic active ingredient. The number of switching steps of the rotary member 120b is the sum of the number of the first fluid passages 113b and the number of the second fluid passages 114 b; the switching passage 121b can communicate with the first fluid passage 113b or the second fluid passage 114b in response to a shift change of the rotary member 120 b.

Further, the first fluid channel 113b has a first water inlet 1131b and a first water outlet 1132b, wherein the first water inlet 1131b is disposed on an outer sidewall of the base box 110b, and the first water outlet 1132b is disposed on the second end 112 b. The second fluid channel 114b is formed with a second water inlet 1141b and a second water outlet 1142b on the first end portion 111b and the second end portion 112b, respectively, the second water inlet 1141b is for introducing filtered water, and the second water outlet 1142b is for discharging a mixed water of the filtered water and the functional water. The number of water outlets on the base cartridge 110b is equal to the number of fluid channels on the base cartridge 110 b. In the present invention, the reason why the second fluid passage 114b flows out the mixed water of the functional water containing the cosmetic effective ingredient and the filtered water instead of the mixed water of the functional water containing the cosmetic effective ingredient and the raw water is: the raw water may contain harmful substances such as impurities and heavy metals, and the mixed water of the functional water and the filtered water flows out of the second fluid passage 114b in order to prevent the harmful substances in the raw water from affecting the absorption of the skin to the cosmetic active ingredients.

Considering that people have different requirements on skin beautifying, the number of the chambers 115b is at least one, wherein the second fluid channels 114b are correspondingly arranged and communicated with the chambers 115b one by one, and the chambers 115b are filled with the functional substance, so that when filtered water passes through the chambers 115b, the functional substance can be partially dissolved in the filtered water to form the functional water. The functional substance placed in each chamber 115b may be a single kind or a mixture of a plurality of kinds of functional substances having a certain cosmetic function; the functional substances placed in the different chambers 115b have different cosmetic functions, so that it is ensured that the mixed water flowing out of each second fluid passage 114b has different cosmetic effects, thereby satisfying different needs of people. In view of the fact that the functional material in the chamber 115b is frequently replaced, it is preferable that the base case 110b is provided in a vertically divided manner. Therefore, has the advantages of convenient use and disassembly,

there are various communication manners between the chamber 115b and the corresponding second fluid channel 114b, and in order to simplify the connection structure, in the present invention, the chamber 115b is formed with a first communication hole 1151b at the first end 111b, the first communication hole 1151b for introducing filtered water, and a second communication hole 1152b communicated with the second fluid channel 114b is formed at the wall of the chamber 115b, so that the functional water is mixed with the filtered water in the second fluid channel 114b through the second communication hole 1152 b. Having fully described the manner of communication between the chamber 115b and its corresponding second fluid passage 114b, those skilled in the art will appreciate the following water flow paths: the raw water enters the first fluid channel 113b through the first water inlet 1131b, and the filtered water enters the second fluid channel through the second water inlet 1141b, and at the same time, the filtered water also enters the chamber 115b through the first communication hole 1151b, and the filtered water entering the chamber 115b enters the second fluid channel 114b through the second communication hole 1152b after dissolving the functional substance, so that the second fluid channel 114b flows out the mixed water of the functional water and the filtered water.

In order to sufficiently and effectively mix the filtered water with the functional substance in the chamber 115b, in the present invention, the first and

second communication holes

1151b and 1152b have a smaller diameter than the second water inlet 1141b, respectively, and the second communication hole 1152b is disposed adjacent to the second water outlet 1142 b.
