Check whether the spray bottle nozzle is blocked by foreign matter. The nozzle of a spray bottle is often composed 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 stick to the nozzle and cause blockage, causing the spray bottle to fail to spray. If there are a lot of attachments on the spray bottle nozzle, wipe the nozzle clean with a towel or the like. If particles get into the nozzle hole, you can use a sharp object to pick out the particles.
Check whether the nozzle has sunk. If you use too much force when using the spray bottle, it may cause the nozzle to sink for a long time, and it will not be able to automatically return to the original position every time. If the nozzle of the spray bottle sinks down, then if you continue to press it, it will not be able to spray anything, so pull the nozzle up and raise it to the original height, and then the nozzle can return to its original position to spray things.

Shake the spray bottle. The nozzle of the spray column in the bottle is fixed in one position for a long time. When the object in this position is sprayed, the remaining objects may not be able to spray because of the unevenness of the remaining objects. If the uneven distribution of the objects in the bottle causes the spray bottle to not spray anything, then you can shake the spray bottle up and down to make the remaining objects evenly distributed, and then you can spray things.
Rotate the nozzle. If the nozzle direction is fixed in one position for a long time, the spray bottle can not spray anything. The nozzle of the spray bottle is generally free to rotate. At this time, you can rotate the nozzle clockwise or counterclockwise to help spray the spray bottle.
Disassemble and check if the spray column is blocked. The key component of the spray column wet spray bottle, if the spray column is blocked, it must not spray anything. At this time, the spray bottle must be disassembled and the spray column cleaned to make it possible to spray the spray bottle.
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 be reimbursed. At this time, you can check the parts that make up the water pump, and if possible, you can replace the parts and repair the water pump. If the pump cannot be repaired, replace it with a new spray bottle.
