In the process of using, the shower head 48 is arranged at the rear far end of the lower side of the wash basin, the sensing function can be manually started when the shower head 48 is used, water is always used for detecting people at the moment, cold water in the hot water pipe 2 is always circulated, when the shower head 48 is used, if the shower head 48 is turned off for a period of time, the shower head 48 is used again, the hot water discharging time can be reduced, the shower head 48 is turned off after being used, the circulation of the hot water is stopped by closing the self-locking key, the hot water pipe 2 is directly communicated with the shower head 48, and the pressure reduction can not occur compared with the pressure reduction before the shower head 48 is arranged, so that the experience of the shower head 48 can be improved.

The sensors in the embodiments are all in the prior art, and specific structures are not described again.

The utility model is intended to cover any alternatives, modifications, equivalents, and variations that fall within the spirit and scope of the utility model. In the following description of preferred embodiments of the utility model, specific details are set forth in order to provide a thorough understanding of the utility model, and the utility model will be fully understood to those skilled in the art without such details.
