Utility Model Content

[0004] To this end, it is necessary to provide a laser infrared dual-sensing faucet that prevents false triggering, so as to solve the problem in the prior art that the faucet is falsely triggered due to water droplets splashing on the sensing window, or due to deformation of the sealing ring or assembly tolerance, the sensing module causes the detection light to be reflected or refracted to the receiving end when there is no user.

[0005] To achieve the above purpose, the inventor provides a laser infrared dual-sensing faucet with anti-false triggering, comprising a housing and a valve core, wherein the housing is provided with a water outlet and a sensing port, the valve core is arranged in the housing and is connected to the water outlet through a pipeline, and further comprises a sensing module, a light shielding sleeve and a light-transmitting plate;

[0012] As a preferred embodiment of the present application, the cross section of the abutment strip of the shading sleeve is an arc, rectangular or triangular structure. By making the cross section of the abutment strip of the shading sleeve an arc, rectangular or triangular structure, the abutment strip is easily arranged for interference fit.

[0044] Please also read Figures 1 to 5 The present embodiment discloses a laser infrared dual induction faucet with anti-false triggering, comprising a housing 10 and a valve core 20, wherein the housing 10 is provided with a water outlet 11 and a sensing port 12, wherein the valve core 20 is arranged in the housing 10 and is connected to the water outlet 11 through a pipeline, and further comprising a sensing module 30, a light shielding sleeve 40 and a light-transmitting plate 50;

[0045] The sensing module 30 is electrically connected to the valve core 20, and includes a first output end 31, a first receiving end 32, a second output end 33, and a second receiving end 34. The first output end 31 and the first receiving end 32 are arranged on one side of the sensing module 30, and the second output end 33 and the second receiving end 34 are arranged between the first output end 31 and the first receiving end 32.

[0046] The light shielding sleeve 40 contacts the sensing module 30 and includes an opening 43 and an abutting strip 41. The opening 43 corresponds to the first output end 31, the first receiving end 32, the second output end 33 and the second receiving end 34 of the sensing module 30. The abutting strip 41 is disposed between the second output end 33 and the opening 43 of the second receiving end 34 and is protruded toward the light-transmitting plate 50.

[0047] The light-transmitting plate 50 abuts against the opening 43 of the light-shielding sleeve 40 and the abutting strip 41 of the light-shielding sleeve 40. On the non-abutting surface of the light-transmitting plate 50 and the light-shielding sleeve 40, a water-cutting convex strip 51 is provided in the area between the second output end 33 and the second receiving end 34 located on the projection surface of the light-transmitting plate 50.

[0048] At least one of the sensing module 30 , the light shielding sleeve 40 and the light-transmitting plate 50 is assembled on the sensing port 12 of the housing 10 .

[0049] According to the above structure, during the assembly process of the laser infrared dual-sensing faucet with anti-false triggering, the first output end 31, the first receiving end 32, the second output end 33 and the second receiving end 34 of the sensing module 30 correspond one by one to the opening 43 of the light-shielding sleeve 40, and are connected to the light-shielding sleeve 40. The other side of the light-shielding sleeve 40 abuts against the light-transmitting plate 50, and the abutting strip 41 of the light-shielding sleeve 40 first contacts with the light-transmitting plate 50, and then the light-shielding sleeve 40 body contacts with the light-transmitting plate 50.

[0050] During use, the light signals output by the first output end 31 and the second output end 33 pass through their respective openings 43, the light signals of the first output end 31 are received by the first receiving end 32, and the light signals of the second output end 33 are received by the second receiving end 34. During the output and reception of the light signals, the light shielding sleeve 40 and the abutting strip 41 abut against the sensing module 30 and the light-transmitting plate 50 to prevent false triggering caused by light passing through the sensing module 30 and the light shielding sleeve 40, and the space between the light shielding sleeve 40 and the light-transmitting plate 50. After installation, long-term use or maintenance, when the light shielding sleeve 40 is partially deformed, although the light shielding sleeve 40 is partially separated from the light-transmitting plate 50, the abutting strip 41 always contacts the light-transmitting plate 50, and continuously maintains the ability to block light. Furthermore, during use, when water splashes onto the light-transmitting plate 50, the water droplets are deformed after contacting the water-cutting ridges 51, and are drained by the water-cutting ridges 51 and drip away from the light-transmitting plate 50, thereby preventing the water droplets from forming an arched arc or spherical structure on the light-transmitting plate 50, causing the light signal to be refracted and reflected in the water droplets to the second receiving end 34, further avoiding false triggering due to refraction or reflection on the light-transmitting plate 50 during use. By providing the abutment strip 41 of the light-shielding sleeve 40, during the assembly process, the abutment strip 41 first contacts the light-transmitting plate 50, and then the light-shielding sleeve 40 contacts the light-transmitting plate 50, so that a double light-shielding structure is provided between the light-transmitting plate 50 and the sensing module 30, and the tolerance, deformation and gap generated during long-term use or during assembly, transportation and maintenance are compensated, thereby improving the light-shielding effect of the light-shielding sleeve 40, and by providing the water-cutting convex strip 51 on the light-transmitting plate 50, it is avoided that the water body forms an arc-shaped reflection structure at the second output end 33 and the second receiving end 34, which are closer to the first output end 31 and the first receiving end 32, thereby greatly reducing the problem of false triggering of the sensing module 30 due to the two sides of the light-transmitting plate 50 during use.
