Problems solved by technology

[0003] Existing sensor faucets use a single infrared emitting and receiving probe, which only detects a single point. The user can only activate the sensor faucet through the optical path formed by the infrared emitting and receiving probes, resulting in poor sensing performance and unable to capture the hand in time. disadvantages of action

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0016] refer to figure 1 , in this embodiment, the induction water outlet system includes an infrared emitting and receiving integrated probe 100 composed of an infrared emitting head and an infrared receiving head, the infrared emitting and receiving integrated probe 100 is electrically connected to the control circuit, and the infrared emitting and receiving integrated The exit of the parallel light emitted by the type probe 100 is provided with a concave lens 110 that diffuses the parallel light, and a hemispherical housing 200 with the virtual focus of the concave lens 110 as the center of the sphere is provided on the side where the light diffuses. Convex lenses 210 are evenly distributed on the casing 200 to re-gather the diffused light into parallel light rays, and a basin 300 is arranged under the hemispherical casing 200 .

Abstract

The invention provides an inductive water outlet system. The system comprises an infrared transmitting and receiving integrated probe consisting of an infrared transmitting head and an infrared receiving head, wherein the infrared transmitting and receiving integrated probe is electrically connected with a control circuit; a concave lens for diffusing parallel rays is arranged at an outlet of the parallel rays emitted by the infrared transmitting and receiving integrated probe; a hemispherical shell using the virtual focus of the concave lens as a sphere center is arranged on the ray diffusion side; convex lenses for refocusing the diffused rays into parallel rays are uniformly distributed on the hemispherical shell; and a counter basin is arranged below the hemispherical shell. According to the system, the rays emitted by the infrared transmitting and receiving integrated probe are divided into a plurality of diffused parallel rays through the combination of the concave lens and the convex lenses, the parallel rays are projected to the counter basin to form a dot detection area, and the range of the detection area is larger than that of the conventional single-line detection.

Description

technical field [0001] The invention relates to the field of plumbing equipment, in particular to an accurately identified induction water outlet system. Background technique [0002] The induction faucet is composed of an infrared transmitting circuit, an infrared receiving amplifier circuit, a control circuit, a solenoid valve and a power supply. The 220VAC is stepped down by the transformer to become 12VAC, and then rectified, filtered, and stabilized to obtain 12VDC for the control circuit to work. Then the infrared rays are emitted by the infrared transmitting circuit, received by the infrared receiving circuit, and then amplified and frequency-selected. Finally, the control circuit controls the opening and closing of the solenoid valve, thereby controlling a process of opening and closing the infrared sensor faucet. This faucet only needs to put hands or other articles under the faucet, and the faucet will automatically release tap water for users to wash their hands ...
