In addition, the water outlet mechanism 210 may further include a water discharging member 215, the water discharging member 215 may be a water discharging tap, a water discharging pipe, or the like, and the water discharging member 215 may be mounted to the shower body 211 and communicate with the water discharging hole 1222 through a corresponding water path of the shower body 211.

The embodiment of the utility model provides a shower device 200, through setting up foretell drainage valve core 100, the user is when using, through controlling driving piece 123 to drive movable valve piece 121 and rotate, when intercommunicating pore 1212 is with outlet channel 112 and different apopores 1223 intercommunication, the rivers that flow in from inlet hole 1221 loop through into water passageway 111 and outlet channel 112 can carry out the water from different outlet mechanisms such as top shower 212 or handheld gondola water faucet 213; before a user uses the top shower 212 or the handheld shower 213, the driving member 123 is controlled to drive the movable valve plate 121 to rotate, so that the communication hole 1212 is communicated with the water outlet 1223 and the water outlet 1222, accumulated water in the top shower 212 and the handheld shower 213 can be quickly discharged through the water outlet 1223 and the water outlet 1222 in advance, the cold accumulated water is prevented from rushing on the body of the user to cause the body to be cooled, in addition, the phenomenon that the accumulated water is frozen and expands to cause the water outlet mechanism 210 to be incapable of normally discharging water in cold weather can be avoided, and the water outlet mechanism 210 is protected.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
