Patent ID: 8625084

Claim:
A distance detection induction device comprising: a housing having a main body and two round openings in a top surface of the main body; a unitary condensing lens comprising an emitting lens, a receiving lens, and a connection part having at least one bend, wherein the emitting lens and the receiving lens are respectively located at the two round openings, and wherein the connection part fixedly connects the emitting lens to the receiving lens; a circuit board mounted inside the main body and bearing multi-electronic components, wherein the circuit board is used for signal processing; an infrared light emitting means including an infrared light-emitting diode mounted on the circuit board, wherein the infrared light emitting means is configured for emitting infrared light to the emitting lens; a light receiving means including a distance detecting sensing module mounted on the circuit board, wherein the light receiving means is configured for receiving and sensing the infrared light which is emitted by the infrared light emitting means, reflected by a target, and focused by the receiving lens; and a shielding cover.
