When the foam mixed liquid with a certain pressure flows through the inner cavity of the foam nozzle, due to the throttling, the flow velocity is increased, the pressure is reduced, a negative pressure is formed, and air is sucked in, and a certain multiple of air foam is formed by the blow-up effect in the nozzle .
