Patent ID: 6996863

Claim:
An automatic faucet control device having a detection means for detecting infrared rays of emitted infrared light, the infrared rays being incident on a target to be detected and being reflected thereby, so as to sense the target coming closer to a spout and then to allow water to automatically run, the device being attached to a washbowl, a washbasin, or a sink, wherein the infrared rays of the detection means are directed toward the washbowl, the washbasin, or the sink; the detection means includes: a first polarization means for allowing a linearly polarized component of the emitted infrared rays to be transmitted therethrough and a second polarization means for allowing a linearly polarized component of received infrared rays to be transmitted therethrough; and planes of polarization of the first polarization means and the second polarization means cross each other, so that the detection means does not detect mirror-reflected rays from a surface of the washbowl, the washbasin, or the sink but detects diffuse-reflected rays from the target.
