Embodiment
[0022] Such as figure 1 Shown, water spray control system of the present invention, mainly by central processing unit, the A / D converter that is all connected with central processing unit, water spray control circuit and power supply, the infrared sensor that is connected with A / D converter, It consists of a step-down circuit connected in series between the infrared sensor and the power supply, and a sprinkler solenoid valve connected with the water spray control circuit; the power supply is also connected with the water spray control circuit. When in use, the infrared sensor is installed on the shower head or on the ceiling above the shower head, and the infrared sensor is used to collect human body signals under the shower head. The solenoid valve of the sprinkler is arranged on the water spray pipe, and is used to control the sprinkler to spray water.
[0023] Specifically, when the human body needs to be flushed, it will move to the bottom of the nozzle, the infrared sens...

The invention discloses a shower water-spray control system based on a voltage reduction circuit. The system is characterized in that the system is mainly formed by a central processor, an A / D converter, a water-spray control circuit, a power source, an infrared sensor, the voltage reduction circuit and a shower nozzle magnetic valve, wherein the A / D converter, the water-spray control circuit and the power source are connected with the central processor; the infrared sensor is connected with the A / D converter; the voltage reduction circuit is connected in series between the infrared sensor and the power source; and the shower nozzle magnetic valve is connected with the water-spray control circuit. The system is simple in structure and low in cost; and the water-spray control circuit thereof can stop water spraying when a shower taker does not need spraying of water, so that waste of water resources can be prevented, and the system is suitable for wide application.
Description
technical field [0001] The invention relates to a control system, in particular to a water spray control system for showers based on a step-down circuit. Background technique [0002] With the progress of society, various kinds of daily necessities have entered the homes of ordinary people, and people are no longer just flushing water in the shower, but usually use bath products such as shower gel or scented soap. It is usually not necessary to flush when using bathing products, and the foam of the bathing products will be stained on the hands during the bathing, so many people think it is troublesome to switch the shower. Outside the spray range of the nozzle, move to the bottom of the nozzle to continue flushing after bathing. Because the shower head continuously sprays water during the bathing process, but the shower person fails to make reasonable use of the water, thus causing a great waste of water resources. Contents of the invention [0003] The purpose of the pr...
