Repair and failure analysis of the nozzle of the plastic spray can

The specifications of spray bottles commonly used on the market are 30ml, 50ml, 80ml, 100ml, 120ml, 150ml, 200ml, 300ml, 500ml, 600ml, 1000ml. It can contain alcohol, 84 disinfectant, skin care products, cosmetics and other daily necessities, plastics Sprinklers are made of plastic. Once broken, most of them are discarded, which will also pollute the environment. It's a pity~ Today, I will give you a systematic introduction to general failure phenomena and troubleshooting.

Remove the nozzle adjustment cap, remove the water divider, and wash it with running water, empty the remaining water or liquid in the nozzle, be sure to empty it, then shake the nozzle, listen carefully to the sound, the interface that connects with the bottle Part of it is shaken with sound, if it can't shake, it is broken.

It is more difficult to repair. At present, only part of the nozzles can be disassembled for inspection and repair. Some are glued and cannot be removed. Under normal circumstances, if you have not fallen, this problem will not occur. For online shopping, you must shake your hand when you get it. If there is no sound, you must communicate with the store. [Throwing during the express logistics process will cause the internal glass beads to jam], unscrew the adjusting cap, pull out the water divider, and clean it again under running water [ It depends on what you sprayed first, wash it a few times to avoid injury] Blow into the nozzle, good nozzle, the air will not blow, the bad one will leak, it will pass, shake it a few times and then blow, or leak , Abandon the repair, the cause of the damage, the non-return glass beads are dislocated, or the inner cylinder is cracked, or the piston is pressed. If there is water leakage when pressed, it means that the piston will leak. If the above problems are not present, then check the water divider and take a look. Whether the water trap hole is gone, you need to clean it up, clamp the nozzle core with the tip of a scissors, and pull out the leisurely pliers. The composition of the water separator: the horn casing, glass beads, small springs, and riser barrels are put into the casing in order. Remember that the glass beads must not be lost.

The spring in the water divider is relatively thin. Not every nozzle can withstand acid and alkali solutions, such as 84 disinfectant and toilet cleaner. Various acids also have a corrosive effect. Some springs will rot. If the spring If it rots, it is necessary to re-select the nozzle. This nozzle is not suitable for you.

The spring is installed in the nozzle factory. Generally, there are different batches of different lengths, and there is no self-checking function in the assembly process.

This is why some sprinklers can be used for a long time, but some sprinklers do not produce water after using them several times.

Install the water divider back and try again to see if it can be used normally.
