Check whether the plastic pump head is blocked by foreign objects. Spray bottle nozzles often consist of one or more very small holes. If the lid is not closed in time after daily use, the fine dust particles in the air will adhere to the nozzle and cause blockage, making the spray bottle unable to spray. If there are a lot of attachments on the plastic pump head, you should use a towel to scrub the nozzle clean. If particles get into the nozzle hole, you can use a sharp object to pick out the particles.

　　Check to see if the sprinkler head is sagging. If you use too much force when using the spray bottle, it may cause the spray head to sag over a long period and cannot automatically return to its original position every time. If the nozzle of the spray bottle sags, then if you press it again, you can't spray anything, so you have to pull the nozzle up, pull it up to the same height as the original, and then return to the original position before you can spray something.

　　Shake the spray bottle. The mouth of the spray column in the bottle is fixed in a position for a long time. When the object in this position is sprayed, the remaining objects may not be uniform, and the spray bottle may not be able to spray anything. If the objects in the bottle are unevenly distributed and the spray bottle cannot spray anything, you can shake the spray bottle up and down, left and right, so that the remaining objects are evenly distributed, and then the spray bottle can be sprayed.

　　Turn the spray head. If the direction of the spray head is fixed in one position for a long time, it can also cause the spray bottle to not spray anything. The spray head of the spray bottle is generally freely rotatable. At this time, the spray head can be turned clockwise or counterclockwise, and it can also help the spray bottle to spray something.

　　Disassemble to check if the spray column is blocked. The key component of the spray column wet spray bottle, if the spray column is blocked, it will not be able to spray anything. At this time, the spray bottle must be disassembled and the spray column should be cleaned before it is possible to make the spray bottle spray something.

　　The pump component is broken. The water pump is the core component of the spray bottle. If the component of the water pump is broken, the spray bottle will also be reimbursed. At this time, you can check the parts that make up the pump, replace the parts if possible, and repair the pump. If the pump is out of repair, get a new spray bottle.
