[0079] In this way, the sensor faucet is assembled. Moreover, the entire sensor faucet is sealed by the first sealing ring 43, the second sealing ring 524, the third sealing ring 113 and the fourth sealing ring 641, which can make the interior of the sensor faucet waterproof and dustproof, thereby increasing the service life of the electromagnetic valve core 70 or the sensor 80.
