Capacitive inductive faucet

Abstract

The invention relates to an automatic control faucet, in particular to a capacitive inductive faucet, which comprises a faucet body, a water inlet pipe, an electromagnetic valve arranged on the water inlet pipe, and an inductive joint electrically connected with the faucet body, wherein the inductive joint is connected with a control unit which comprises a microprocessor; the microprocessor controls a pulse generating circuit to generate a pulse signal which is sent to the inductive joint after passing through a filter stabilizing circuit; and the faucet body is used as an inductive part so that an induction field around the faucet body is formed centering on the faucet body. The inductive faucet is only inductive to a human body and does not react to a non-living object, and the induction range is between 0 and 5 centimeters; and when a human hand gets close to the faucet, the amount of electric charge acquired by the faucet is increased, and the faucet can detect the approach of the human hand according to a preset threshold value so as to control the electromagnetic valve to release water.

Description

technical field [0001] The invention relates to an automatic control faucet, in particular to a capacitive induction faucet. Background technique [0002] The existing induction faucets mainly use active infrared induction. The probe emits infrared rays, and by receiving the reflected infrared signal, the position of the object is judged, and the function of water supply or water stop is realized. This kind of product must have a sensing window on the faucet body, which limits the appearance design of the faucet body. At the same time, due to the limited sensing angle of the sensing window, the hand must be placed directly in front of the sensing window when sensing with the hand. Excessive deviation will make it If the hand is not sensed, the water supply will be stopped, causing inconvenience to people. At the same time, the infrared signal probe can sense any passing objects, which is easily disturbed by the environment, and it is easy to mistakenly discharge water, resu...

This kind of product must have a sensing window on the faucet body, which limits the appearance design of the faucet body. At the same time, due to the limited sensing angle of the sensing window, the hand must be placed directly in front of the sensing window when sensing with the hand. Excessive deviation will make it If the hand is not sensed, the water supply will be stopped, causing inconvenience to people

At the same time, the infrared signal probe can sense any passing objects, which is easily disturbed by the environment, and it is easy to mistakenly discharge water, resulting in a waste of water resources.

Moreover, the sensing probe part is easily affected by moisture, which will form water in the probe and damage the probe
