Infrared induction-type faucet

Abstract

The invention discloses an infrared induction-type faucet. The infrared induction-type faucet comprises a faucet body, wherein the water outlet of the faucet body is provided with an infrared sensor; a steering engine is arranged on a pipeline of the faucet body; the faucet further comprises a photoelectric coupler, an amplifying circuit, a single chip microcomputer and a PWM motor speed regulator which are sequentially connected; the photoelectric coupler is connected with the infrared sensor; and the PWM motor speed regulator is connected with the steering engine for controlling the rotation angle of the steering engine, so that the water outlet amount is controlled. By adopting the infrared induction-type faucet, the water outlet amount can be freely controlled according to the distance between the hand of a person and the faucet, and the situation that a traditional infrared sensing device cannot sense the hand or the water outlet amount is overlarge cannot happen. In order to avoid the situation that the equipment is damaged because of continuous closing and opening of a faucet valve, the steering engine is additionally arranged on the faucet, so that the use damage rate of a valve switch during use of the faucet is greatly reduced; and the problem that the equipment needs to be changed in a long term is reduced to a certain extent.

Description

technical field [0001] The invention relates to a faucet, in particular to an infrared induction faucet. Background technique [0002] Infrared sensor faucets originated in developed countries such as Europe and the United States in the 1970s. They are used in public places, AC power supply or DC power supply, and use infrared induction. When you reach out in the sensing area, the water will come, and when you leave the sensing area, the water will stop. The water is automatically completed by the sensor without touching the faucet, which prevents secondary pollution after washing hands and avoids the infection of diseases. [0003] However, today's infrared sensor faucets do not pay much attention to water-saving functions. The same amount of water supply is sensed every time the hand is stretched out, and the amount of water supply cannot be adjusted manually. When the user needs a thinner water flow, due to the non-adjustability of the water flow, a large amount of water...

[0003] However, today's infrared sensor faucets do not pay much attention to water-saving functions

The same amount of water supply is sensed every time the hand is stretched out, and the water supply amount cannot be adjusted manually. When the user needs a finer water flow, due to the non-adjustability of the water flow, a large amount of water resources are wasted.
