the right side of the collision mixing chamber 8 is communicated with a static mixing chamber 9; the static mixing chamber 9 is in communication with the spray head 10; the static mixing chamber 9 is a high-efficiency mixing device without moving parts, and the basic working mechanism is to change the flow state of the fluid in the tube by utilizing the mixing unit body fixed in the tube, so as to achieve the purposes of good dispersion and full mixing of different fluids.
The spray head 10 comprises a spray nozzle 21, an atomization cap 23 and an air splitter plate 22, wherein the atomization cap 23 is sleeved on the right side of the spray nozzle 21; the air splitter 22 is positioned in a cavity formed by connecting the atomizing cap 23 and the nozzle 21; the air splitter plate 22 is fixed to the nozzle 21.
