Existem duas razões principais pelas quais o bico de aerossol pressionado para cima e para baixo não pode ser pressionado
1. A mola está quebrada.
2. The nozzle cap tube is broken or the protrusions on both sides of the nozzle cap are rough. You can use pliers to pull out the pressed nozzle cap, and then you can see that there is a pipe standing upright. Press it with your fingers or pliers, and it can press and spring up, which means that the internal spring is OK. If it can't spring up, it means that the internal spring has been broken and damaged. When reinstalling the nozzle cap, pay attention to the orientation chute and the positioning protrusion. Pressing and springing, but no fog, indicates that the internal glass ball or steel ball is reset abnormally (it can be solved by shaking up and down), or the spray hole is blocked.
