The second gear 27 then drives the driving rack 42 to move, so that the two liquid storage boxes 3 on the driving rack 42 move synchronously.

In the process that the transmission rack 42 drives the two liquid storage boxes 3 to move synchronously, one of the liquid outlet pipes 351 can move to the position of the liquid inlet 121, as shown in fig. 7, at this time, under the elastic force of the extension spring 352, the liquid outlet pipe 351 is inserted into the liquid inlet 121. Then the driving rack 42 drives the two liquid storage boxes 3 to move continuously, at this time, the inserted liquid outlet pipe 351 cannot move, so that the liquid outlet pipe 351 and the liquid storage box 3 thereof move relatively, the block-shaped structure formed by the moving block 35 and the assembling block 353 slides in the lower air cavity 34, air in the lower air cavity spring 341 and the lower air cavity 34 is compressed, at this time, the lower air door 322 is closed, and air cannot go out, so that the air enters the liquid storage cavity 31 through the side air channel 32 (at this time, the upper air door 321 is pushed open by air pressure), and under the action of the air pressure, the functional liquid in the liquid storage cavity 31 flows into a channel in the moving block 35 through the discharge hole 311 at the bottom and flows into the liquid mixing cavity 125 through the liquid outlet pipe 351.

The handle 23 is rotated in the other direction to allow the functional liquid in the other cartridge 3 to flow into the liquid mixing chamber 125.

After the liquid is discharged, the button 231 is released, the button 231 is reset under the action of the button spring 232, the pressure in the internal flow passage is reduced, the telescopic rod 233 is also withdrawn from the jack 241, and at the moment, the handle 23 and the gear ring 24 are out of synchronization. Under the condition of no stress, the return spring 44 enables the limiting slide block 43 to move to the middle balance position, the transmission rack 42 drives the two liquid storage boxes 3 to also move to the balance position, and in the process, the liquid outlet pipe 351 is moved out of the liquid inlet 121 by virtue of the inclined surface structure at the end part of the liquid outlet pipe. By the return process, the upper valve 321 is closed, the lower valve 322 is opened, and the external air is supplied to the lower chamber 34.

After the liquid is discharged, the liquid mixing chamber 125 already contains the functional liquid, and at this time, water is discharged by conventional operation, enters the liquid mixing chamber 125, is mixed with the functional liquid, and is sprayed from the shower head for use. The trouble of need taking shower cream or shampoo alone has been avoided in this application, convenient operation.

In the present application, some assembly structures which are not described in detail are all conventional structures in the prior art, and some sealing structures and sealing sliding structures in the present application are also conventional technologies.

More than, this application provides a multi-functional water subassembly for in bathroom, can normally go out cold water and hot water, can also extrude into functional liquid in mixing the sap cavity, goes out water together after mixing with water, has avoided getting alone the trouble of taking functional liquid, convenient operation, stable in structure and linkage are strong.
