To quickly wash a car, a window of a house, to clean a grate with a jet under pressure - there is nothing easier when using this home-made mini-sink. It runs on a built-in battery and can be used anywhere. Just pour powerful liquid or just water into the bottle and that’s it, the device is ready for use. No wires or electricity are needed - which is very convenient.
The compact size allows you to take it with you wherever you go. A water pump develops a pressure of 0.90 MPa, which is a lot for such a crumb.
Will need
- .
- .
- Non-latching switch.
- .
- Dvet pipe PVC 75 mm in diameter and 50 mm.
- Two plugs for each pipe.
You will also need a good glue, preferably based on epoxy. Transparent silicone hose. Wires to connect.
Making a mini hand wash
So, we measure the length of the pump and by its dimensions we saw off a pipe with a diameter of 75 mm.
We measure from the top of the pump the distance to the inlet and outlet nozzles. And then at the same distance we drill a hole in the PVC pipe.
To get the pump in, we cut a groove with scissors from one side to the hole.
We insert the pump.
We derive a branch pipe.
We take here such a nozzle with a fitting at the end (such are used for watering the garden):
Dress the hose and cut it.
A large length is not needed, as it will be worn directly on the pump outlet.
At the inlet pipe, you need to choose an angular adapter. But, unfortunately, I did not find this.
So I cut one piece off the tee.
And he soldered it through a copper hat.
She also puts on a short tube. And the second side is inserted into the bottle cap. Glue with glue.
So that when water is not taken in, a vacuum is created, we drill a couple of small holes for air passage.
We put on the hose along the length of the bottle, which will be screwed on.
We put the second end on the pump.
This is how it should look.
But the design turned out to be not quite stable - the bottle shook from side to side. To avoid this, a metal hexagon - boss, was glued between the body and the cover.
Next, we take a 50 mm pipe under the battery and cut it off.
Approximately this will be the placement.
At this distance, we cut off the PVC pipe by 20 m. Glue it to the plug.
We drill a hole in another plug.
And glue the second end to it.
We will also drill a hole forgotten earlier.
We draw the wires from the pump through these holes and a small tube.
Find the limit switch.
In the battery compartment, we cut out the groove under the button.
We fix it in the case with hot glue.
Solder the wires to the button.
Next to the battery connection block.
Install the battery.
We close all stubs.
Pour water and go to experience.
To prevent the nozzle from knocking out pressure, tighten the tube with nylon clamps.
The pressure is beautiful. You can also draw water from a larger tank.
And here is a specific task: cleaning the air conditioner.
Thanks to the powerful jet, all the dirt scatters quickly. In a couple of seconds, the dirty grill turned into crystal white.
So the thing is very necessary in any household.The battery lasts for 30 minutes of continuous operation of the pump - this is more than enough!
