Description

Inductive faucet

The present invention relates to a water outlet device, and more particularly to an inductive faucet.

An inductive faucet is known, comprising a sensing element and a solenoid valve. The sensing component controls the switch of the electromagnetic valve by using an infrared sensing principle, that is, when the hand is placed in the sensing range of the sensing component, the solenoid valve is opened to make the faucet out of water, and when the hand leaves the sensing component When the range is measured, the solenoid valve closes to stop the faucet from flowing out of the water. However, because the faucet cannot prevent the false sensing action caused by abnormal sensing sources (such as insects or pots and pans), even if the user wants to be close to repairing the faucet, or approaching the faucet to perform affairs unrelated to water use, It is also easy to accidentally cause misuse of the action and cause waste of water resources.

There has also been developed an inductive faucet that can prevent abnormal sources of induction, such as the patented bulletin No. M400539 "Stable Induction Multi-Function Faucet", which includes a main probe, a pair of probes, and An insurance probe. When the safety probe is triggered simultaneously with the main probe, the faucet can provide a short-time water discharge function, and when the safety probe is triggered simultaneously with the auxiliary probe, the faucet can provide long-time water discharge. The function, and the primary and secondary probes can be triggered only when the safety probe is triggered, so that the false induction of the abnormal sensing source (such as insects or pots and pans) can be avoided, and the water saving effect can be achieved. . However, the new type still cannot prevent the user from being close to repairing the faucet, or approaching the faucet to perform a missensing when it is not related to water use. At this point, the user can only turn off the water supply to the faucet or turn off the power supply to the sensor to prevent unnecessary waste of water. However, this closing action usually takes the user's time and effort, and the operation is inconvenient.

Therefore, the object of the present invention is to provide an inductive faucet that can easily and quickly switch the inductive water discharge function.

Therefore, the novel inductive faucet comprises a casing, a water outlet pipe, a bottom water inlet pipe, a non-contact sensing unit, a solenoid valve, a touch-sensitive main switch, and a control unit. The water outlet pipe is disposed in the casing. The bottom water inlet conduit is disposed in the housing. The non-contact sensing unit is disposed on the housing and includes at least one inductor. The sensor is used to sense an object approaching change and output a sensing signal. The solenoid valve is disposed in the housing and is connected between the water outlet pipe and the bottom water inlet pipe. The touch-type main switch is disposed in the housing and can be operated to output a working signal, and can be operated to output a sleep signal. The control unit is electrically connected to the non-contact sensing unit, the electromagnetic valve and the touch-sensitive main switch, and receives the working signal to switch the inductive faucet to an operating state, and receives the sleep signal to switch the inductive faucet to a sleep state, in the working state, the control unit receives the sensing signal and controls the solenoid valve to act, In the sleep state, the control unit controls the solenoid valve not to communicate with the water outlet pipe and the bottom water inlet pipe.

The function of the present invention is to operate the touch-type main switch to output one of the working signal and the sleep signal, so that the control unit controls the solenoid valve to perform a corresponding action, and can switch the inductive type easily and quickly. The state of the faucet can be used to switch the induction water function easily and quickly without switching the water source or the induction power source.
