ABSTRACT:
An anchor structure for sensors of faucets is located in a sensing faucet. The sensor has a detection side and at least one notch on another side opposite to the detection side at an elevation same as an annular groove formed on an inner wall of a faucet body. An elastic clipping ring is provided to latch in the annular groove and the notch of the sensor to form a bucking effect to anchor the sensor at a selected location in the faucet. The elastic clipping ring is hollow and annular to provide a passage for watering piping and electric wiring. The structure is simpler and can be installed and removed rapidly.
