[0029] As shown in Figure 2 , the main plate 1 and the connecting plate 2 are provided with a static mixer 4; the static mixer 4 can achieve the purpose of fully mixing between fluids; the upper end of the static mixer 4 is connected with a shunt plate 6; the shunt plate 6 can balance the flow of the liquid flowing through, balance the heat of the system, and uniformly fill each outlet. The upper end of the shunt plate 6 is connected with the bottom surface of the spray head 7; the lower end of the connecting plate 2 is provided with a feed joint 5; the liquid to be processed from outside is introduced into the device through the feed joint 5; the lower end of the static mixer 4 is sealingly connected with a buffer 10; the buffer 10 can effectively reduce the excessive pressure generated when the liquid flows in, so as to prevent damage to the static mixer 4; the feed joint 5 is connected with the buffer 10; the solution is introduced into the static mixer 4 through the feed joint 5, the static mixer 4 will shunt the solution through the shunt plate 6, flow into the spray head 7, and then be spun through the nozzle 71.

[0030] As shown in Figure 2As shown, the main board 1 has through holes 8 at both ends; the connecting plate 2 has threaded holes 9 at both ends; bolts 3 are installed in the through holes 8 and the threaded holes 9; the bolts 3 are adapted to pass through the through holes 8 and engage with the threaded holes 9 so that the main board 1 and the connecting plate 2 are in contact; the main board 1 and the connecting plate 2 are movably connected, making installation and disassembly convenient.

[0031] like Figure 3 As shown, the main board 1 is formed by bonding a rust-proof plate 11 and a sound-absorbing plate 12 together; wherein, the lower end of the rust-proof plate 11 is connected to the sound-absorbing plate 12; this prevents the main board 1 from rusting over time when it comes into contact with air, water or other liquids; and reduces the noise generated when the nozzle 7 is working.
