If the watering can is not tightened, the pot body is damaged and leaks, or the water in the pot is insufficient, the air pressure will be insufficient and water cannot be sprayed. Tighten the watering can to ensure that there is enough water in the pot. Under normal circumstances, add about 2/3 of water, tighten the upper cover and pump enough air, and press the spray button to resume spraying. If the pot body is damaged, only the watering can be replaced.
The nozzle of a spray bottle usually consists of one or more very small holes. These small air holes are easily blocked by dirt in water or dust in the air, which makes the watering can not spray water. You can scrub the nozzle with towel and clean water. If there are particles drilling into the nozzle hole, you can pick out the particles with needles, iron wires and other tapering things.
Water pump is the core component of spray bottle. If the parts of the water pump are damaged, the spray device of the spray bottle will fail. If possible, replace parts and repair the water pump. If the pump cannot be repaired, it must be replaced with a new one.
