An infrared sensor faucet

Abstract

The invention relates to the field of induction faucets, in particular to an infrared induction faucet. The infrared induction faucet comprises an induction mechanism, a control mechanism, a water inlet pipe, a driving mechanism, a backflow leakage-proof mechanism, a water outlet mechanism and a filter mechanism; the side wall of the water inlet pipe communicates with a water outlet pipe through asecond connecting pipe of a hollow truncated cone-shaped structure, when the induction mechanism induces that a person needs to wash the hand, a pulse electromagnetic valve is opened through the control mechanism to enable a connecting sleeve and a second connecting shaft to be disconnected, when the water flow reaches the interior of the water outlet pipe, the driving mechanism is driven to rotate, and therefore an impeller drives an electric generator to rotate to store power for a battery; the problem that the battery is not replaced in time, and the hand cannot be washed is solved, when the battery is in power, the connecting sleeve slides on the surface of a first connecting shaft, the electric generator is not driven by the impeller, operation is easy, the backflow leakage-proof mechanism is arranged between the driving mechanism and the water outlet pipe, a 45-degree angle is arranged between an overflow pipe and the water outlet pipe, water in the interior of the water receiving disc flows to the water outlet pipe again, and water splashing can be avoided.

Description

technical field [0001] The invention relates to the field of induction faucets, in particular to an infrared induction faucet. Background technique [0002] The induction faucet is based on the principle of infrared reflection. When the human hand is placed in the infrared area of ​​the faucet, the infrared rays emitted by the infrared emitting tube are reflected to the infrared receiving tube due to the blocking of the human hand, and the signal is sent through the microcomputer processing in the integrated circuit. To the pulse solenoid valve, the solenoid valve receives the signal and opens the valve core according to the specified command to control the water from the faucet; when the human hand leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve core is reset by the internal spring. Control the water off of the faucet. [0003] However, in some existing places such as factories with more practical use, the frequency...

Problems solved by technology

[0006] Aiming at the problems in the prior art, the present invention provides an infrared sensor faucet. The side wall of the water inlet pipe is connected to the water outlet pipe through a second connecting pipe in a hollow frustum-shaped structure. When the induction mechanism senses that someone needs to wash their hands, it is opened by the control mechanism. The pulse solenoid valve disconnects the connecting sleeve from the second connecting shaft, and drives the driving mechanism to rotate when the water flow reaches the inside of the outlet pipe, so that the impeller drives the generator to rotate to store electricity for the battery, avoiding the problem of not being able to wash hands if the battery is not replaced in time. When there is electricity, slide the connecting sleeve on the surface of the first connecting shaft, so that the generator is no longer driven by the impeller, and the operation is simple. There is a lot of water leakage from the water pipe. Because the angle between the outlet pipe and the water inlet pipe is 45 degrees, it is conducive to water flow and reduces water leakage from the first connecting pipe. There is an overflow pipe connected between the bottom of the water tray and the outlet pipe. At 45 degrees, the water inside the water tray can flow to the outlet pipe again to avoid water splashing
