Abstract

The invention discloses an induction time-delay faucet. The induction time-delay faucet is characterized in that the induction time-delay faucet comprises a 12V direct-current power supply, a microwave induction and detecting circuit and a monostable time-delay and electronic control faucet driving circuit; the model of a microwave induction controller IC2 in the microwave induction and detecting circuit is TX982; the monostable time-delay and electronic control faucet driving circuit is composed of a time-base circuit IC1, a resistor R1, a timing capacitor C1 and an electronic control faucet, and the model of the time-base circuit IC1 is NE555. According to the induction time-delay faucet, a new path is found; the induction time-delay faucet is made of common electronic components completely; the induction time-delay faucet has the advantages of being simple in structure, low in manufacturing cost, capable of withstanding voltage and convenient to repair, and being convenient to operate, sanitary and low in power consumption and the like in the aspect of usage; the faucet is suitable for the occasions such as hotels, office buildings, hospitals, passenger stations and airports.

Description

technical field [0001] The invention belongs to the technical field of electronics and water saving, and relates to an induction time-delay faucet. Background technique [0002] Due to the rapid advancement of electronic technology, infrared automatic faucets have made a lot of technical improvements. The power supply of the faucet has been developed from 220V AC to DC power supply. After switching to DC power supply, people's concerns about using 220V AC power have been eliminated. [0003] At present, there are two main types of mainstream infrared light control faucets: [0004] 1. Blocking infrared automatic switch faucet, when people reach out to wash, the infrared beam is blocked, and the faucet automatically turns on and discharges water; when the body leaves after washing, it automatically turns off after a few seconds of delay in discharging water. [0005] 2. Infrared light control faucet, the circuit of infrared light control faucet is divided into sending and r...
