Description

Technical Field

[0002] In existing public facilities, for the sake of public hygiene and convenience, water faucets are often set to automatically sense water. Existing automatic sensing water faucets are generally single sensing faucets, which are set to start water flow through infrared sensing when in use, and automatically shut off the water flow after about 5 to 10 seconds, until the next sensing starts water flow again.

[0003] However, in many usage scenarios, the overly fixed sensing usage time is not flexible and is not suitable for different usage scenarios. Therefore, relevant technical personnel have developed a multi-sensor faucet (double-sensor faucet). However, the sensing components and control components of the existing multi-sensor faucet (double-sensor faucet) are designed as an integrated mode and are assembled at the water outlet of the faucet. Therefore, the outer shell of the faucet needs to leave a larger accommodation space for this, which means that the outer shell of the faucet will be designed to be relatively bulky, occupying space and not beautiful; or the outer shell of the faucet will have a large protrusion, which is also very unsightly. Summary of the invention
