Referring to fig. 5 and 6, in use, the control assembly can rotate relative to the valve body between a water-closing position and three water-outlet positions, specifically, when the movable plate 35 is in the water-closing position, the first water inlet 351 is blocked by the blocking plate 362, the water passing groove 352 is positioned above the first water outlet 361, the first water passing path 301 is closed, the second surface 353 blocks the second water outlet on the fixed plate 36, and the second water passing path 302 is closed; when the movable plate 35 is at the water outlet position, the first water inlet passage 351 is communicated with the first water outlet passage 361, the first water passing path 301 is opened, the water passing groove 352 is communicated with the second water inlet passage 366 and any one of the second water outlet passages, and the second water passing path 302 is opened.

Specifically, in the shower or the water outlet device provided in this embodiment, hot water enters the first water inlet 321 of the water diversion valve core 30 through the first water inlet path, when the moving plate 35 is in the water closing position, the hot water is cut off, when the moving plate 35 is in the water outlet position, the hot water enters the first communication water path 21 after passing through the water passing cavity, the first water inlet opening 351, the first water outlet opening 361 and the first water outlet opening 383, and then enters the thermostatic valve 50, the hot water and the cold water are mixed in the thermostatic valve 50 and then output as constant temperature water, and are input to the second water inlet 384 of the water diversion valve core 30 through the second communication water path 22, and then the constant temperature water passes through the second water inlet opening 366 and any one of the second water outlet openings and then is discharged from the corresponding water outlet path, and forms shower, top spray or faucet water.

The utility model provides a pair of divide water valve core and corresponding play water installation and shower, through opening and close of the water route of dividing water valve core 30 control hot water intaking, guarantee when hot water is intake, go out water and be in the open mode, when hot water closes the intake, go out water and be in the closed mode to the problem of cold and hot water scurrying water has been avoided appearing.

The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
