Household multifunctional water-saving device

The invention discloses a household multifunctional water-saving device. In the device, a single chip microcomputer (SCM) is used as the control core, a water flow velocity sensor can provide a water flow velocity signal for the SCM control core, a stepping motor drives a water-saving value to realize the regulation of water flow, and the expected water flow velocity is set through a keyboard while a digital tube is used to display the set value and current value of the water flow velocity. The device has two start modes of infrared induction and keyboard, a user can control the device to work by directly pressing a start button or a stop button and control a tap to open or close through the infrared induction mode. The device has complete functions, high practicability, low cost, simple use method and intuitive digital display, greatly reduces the inconvenience caused by the current household water-consuming device, effectively achieves the purpose for saving water and is suitable to popularize for use.
