The working principle of the electric paddle board air pump is to use compressed air to push the paddle forward, thereby realizing functions such as liquid delivery, compression and injection. Specifically, when the air pump starts working, the paddle board is moved forward by the compressed air. During the movement, the liquid at the narrow mouth is sucked into one side and then enters the inside of the paddle board. As the paddle board moves, the liquid is squeezed into the compression chamber, and the internal pressure gradually increases. When the pressure reaches a certain level, the liquid will spray out from the outlet and work with the compressed air through the liquid seal chamber, so that the sprayed liquid has energy, which can realize the automatic formation of spray or mix with dry gas during powder manufacturing to achieve uniform spraying.
