Electric Water Pump - Water Dispenser (Automatic) for Few Bucks

cults3d

Hi, friends! Looking at pumps in the shop for a 5 gallons water bottle (18,9 L) I understood, that they are not the thing that I want to see. So, I modelled it by my own. For this project you'll need: 1 vipe mini motor pump (like this https://www.amazon.com/Vipe-Micro-Submersible-Motor-Water/dp/B01N0X3CW4/ or like this from AliExpress) 2 x 3,7 volt 18650 batteries or any power supply with voltage around 6-8 volts (there are enough volume in the body of the pump, don't worry) wires (about 2-3 meters 0.25-0.35 mm2 will be enough) silicone tube with 7-8 mm diameter. 1 power switch 3,9 x 3 x 0,4 inches https://www.amazon.com/ZUPAYIPA-Solder-Rocker-Switch-Toggle/dp/B01N2U8PK0/ 1 x SMD Button 12 x 12 x 7.5 mm — https://www.amazon.com/Uxcell-a11111400ux0132-Momentary-Tactile-Button/dp/B0090VQLDK/ 1 x 510 Ohm resistor https://www.amazon.com/EDGELEC-Resistor-Tolerance-Multiple-Resistance/dp/B07QK8VRZX/ 1 x LED Light Diode https://www.amazon.com/MCIGICM-Circuit-Assorted-Science-Experiment/dp/B07PG84V17/ 2 screws with self cutting thread for holding button. So, print this and connect. Put some glue between Bottle Cap and Body Pump. You'll have two modes: fill water while pressing the button, or the water will fill after you turn on the switch without need to hold a finger. I prepared a simple circuit image for better understanding how to connect it. But, it's not hard, don't be afraid:) Suppose, this thing will make somebody happy:)
