It solves the problem that part of the medicine precipitates and precipitates during spraying, causing the nozzle to be blocked. The long-term accumulation of precipitation can easily cause the filter to be blocked, making it difficult for the liquid medicine to pass normally, reducing the amount of liquid medicine sprayed and affecting the spraying efficiency.
