Problems solved by technology

There are many types of sprayers, and the commonly used ones are knapsack-type manual sprayers. Manual sprayers are light in weight, simple in structure, and cheap in price, but the disadvantage is that it is inconvenient to operate. One hand is used to hold the spray gun, and the other is used to hold the air pressure lever , the operation is very tiring

Therefore, in recent years, people have developed an electric sprayer. The electric sprayer does not need to be manually inflated, and the operation is more convenient. However, the electric sprayer is powered by a battery. Not only does it need to be charged frequently, but the service life of the battery is short and it is easy to age. affect time efficiency

On the other hand, for the spraying of fruit trees, manual and electric sprayers often have insufficient spray pressure and cannot meet the spraying needs of tall fruit trees.
