생각보다 만들기 쉬운 자동분무기

The old sprayer had only the pump and battery, but the performance is better than expected. 1.Pump: -12v dc 80w diaphragm pump automatic pressure booster (P00203-1) -23,490 KRW/ 1 piece ※ 80w is very inconvenient for the nebulizer to be carried on the back because the vibration and noise are excessive. I like installing a small motor These days, the automatic sprayers on the market use a motor of about 25w. 2. Nozzle -Spray side: Use existing hose -The suction side: The existing one was short, so the air conditioner drain hose was 30cm 3, battery -First of all, buy a cheap battery 12v7ah: It's too heavy. ★ When you use 18650 battery, it is light and compact -18650 battery 3.7v × 3 -18650 battery hold 3 hole -Other: You can make it light by using a battery charger or a'charge/discharge circuit'. ※ It is easy to make, so if you apply it, you will make it better.
