Embodiment
[0025] Such as figure 1 As shown, the water spray control system of the present invention mainly consists of a central processing unit, an A / D converter connected with the central processing unit, a water spray control circuit and a power supply, and a signal filter circuit connected with the A / D converter , an infrared sensor connected to the signal filter circuit, a sprinkler solenoid valve connected to the water spray control circuit, and a steady flow circuit connected in series between the power supply and the water spray control circuit; the power supply is also connected to the infrared sensor . 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.
[0026]Specifically, when the human body needs to be flushed,...

The invention discloses a water spray control system for shower based on a steady-current signal filter circuit. The water spray control system is characterized by comprising a central processing unit, an A / D converter, a water spray control circuit and a power source which are connected with the central processing unit, a signal filtering circuit which is connected with the A / D converter, an infrared sensor which is connected with the signal filtering circuit, a nozzle solenoid valve which is connected with the water spray control circuit, and a current stabilizing circuit which is connected in series between the power source and the water spray control circuit. The water spray control system is simple in structure and low in cost. The water spray control circuit can stop water spray when a bather does not need water. Therefore, waste of water resource is prevented. The water spray control system is suitable to be popularized and applied.
Description
technical field [0001] The invention relates to a control system, in particular to a water spray control system for showers based on a steady-flow signal filtering 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] Th...
