In-depth analysis of the cause of Micro Sprayer blockage
High water hardness: The water contains a large amount of calcium and magnesium ions, which are deposited in the nozzle hole to form scale, which will clog the nozzle over time.
Impurity deposition: Suspended sediment, rust and other impurities in the water will also enter the nozzle with the water flow, gradually accumulate and clog the nozzle hole.
Nozzle material problem: Some inferior nozzle materials are easily corroded by water, causing the nozzle hole to deform or shrink, affecting the spray effect.
High frequency of use: Frequent use of micro-sprayers, the nozzle is in working state for a long time, which is more prone to wear and blockage.
Spray angle is too small: When the spray angle is too small, the sprayed water flow is concentrated, and it is easy to form water droplets at the nozzle mouth. These water droplets will leave minerals after evaporation, causing the nozzle to clog.

Detailed explanation of the unblocking method
Remove the nozzle:
After turning off the water source and power off, gently rotate the nozzle counterclockwise to remove it.
Be careful to protect the O-ring on the nozzle to avoid damage.
Ultrasonic cleaning:
Put the disassembled nozzle into an ultrasonic cleaning machine with an appropriate amount of clean water, and select the appropriate cleaning mode and time for cleaning.
Ultrasonic cleaning can effectively remove fine dirt and scale in the nozzle hole.
Chemical soaking:
Soak the nozzle in white vinegar, citric acid or special descaling agent for 30 minutes to 1 hour.
Acidic solution can effectively dissolve scale and minerals.
Note: The soaking time should not be too long to avoid corrosion of the nozzle.
Needle dredging:
Use a fine needle or toothpick to gently dredge the nozzle hole, pay attention to the strength to avoid damaging the nozzle.
Manual grinding:
If there is hard scale in the nozzle hole, you can use fine sandpaper to gently grind it to remove the scale.
Replace the nozzle:
If the above methods cannot solve the problem, it is recommended to replace a new nozzle.

Effective measures to prevent clogging
Use soft water: Try to use soft water or water treated by a water softener.
Install a filter: Install a filter at the water source to filter out impurities in the water.
Regular cleaning: Clean the nozzle and filter regularly according to the requirements of the instructions.
Choose high-quality products: Choose a well-known brand of micro-sprayer, whose nozzle material and craftsmanship are relatively good and not easy to clog.
Avoid long-term low-flow spraying: Long-term low-flow spraying can easily cause minerals to deposit at the nozzle mouth, increasing the risk of clogging.
