Sustainable Water Mechanism: Shower Head

grabcad

Just like any other shower head, but features a sensor in the middle that will detect when a person is under the water or not. This will allow the water to turn off while people step out of the water to wash their hair, bodies, or complete any other given tasks they may have, then back on when they need it. The 3D-printed component would be a casing for the electronics in the shower-head.According to "MAC FAUCETS, LLP", in an automatic faucet, there are four main components: Solenoid valves, sensor and control electronics, a power source, and a faucet. This design is based on that technology, but put into a shower head rather than a faucet. The solenoid valve's purpose is to physically start and stop the flow of water. The sensor sends the signal to the valve telling it whether to open or close, or start or stop the flow of the water. To further explain this technology, I am including an informational paragraph that I pulled from Mac Faucets, LLC. "Automatic faucets are presence sensors and not motion sensors. They employ Active Infrared technology which senses "presence" and not "movement" of objects. Active infrared technology, like the name implies is actively emitting infrared light and actively waiting for this light to come back to it. On the frequency spectrum, infrared light lies between radio waves and light waves that are visible to the human eye. To achieve the task of emitting and receiving, faucet sensors employ 2 key components: an emitter AKA transmitter and a collector AKA receiver each about 1/4" in diameter and 5/16"long or smaller. These components are housed within the sensor capsule that is located either at the neck of the faucet spout, in a separate sink hole to the side of the faucet spout, or in a special compartment up next to the aerator. The emitter is constantly emitting infrared light in a blinking method, that is, the emitter is constantly blinking in the same way that turn signals on automobiles blink when the turn signal lever is engaged. The collector on the other hand, is always ready to receive (collect) this blinking light, and when it does, the control electronics take a factory preset action, in the case of battery powered faucets, the control electronics send an electrical pulse to the solenoid valve asking it to open. When the collector no longer receive the blinking light, the control electronics will then send yet another electrical pulse to the solenoid, this time, asking the solenoid to close."http://www.macfaucets.com/index.php?route=information/information&information_id=10
