Description

Technical Field

[0001] The utility model relates to the technical field related to faucets, and more specifically, to a faucet. Background Art

[0002] Existing faucets are very popular among users because they can be operated by contactless sensing. Specifically, the most common control method is series water supply, that is, it is necessary to first adjust the water temperature through a mechanical handle and turn on the water outlet of the instrument handle, and then use sensing to control the solenoid valve connected in series in the water circuit to realize or shut off the water outlet. The advantage is that when the faucet is not used for a long time, the mechanical valve can be closed to avoid long-term water leakage caused by a malfunction of the solenoid valve. However, when the sensing device fails or the power supply device is powered off, the faucet cannot continue to be used, which causes a pain point in use. Therefore, it is necessary to design a technical solution that can overcome the above-mentioned defects to a certain extent. Utility Model Content
