Specific embodiment
As shown in Figure 1, and combining the mushroom head nozzle 13 shown in Fig. 2, Fig. 6, in the present invention includes mushroom head shank 2 and mushroom
Mushroom head portion 1, the mushroom head shank 2 is interior to be equipped with intake tunnel 3, and the mushroom head head 1 is equipped with spray aquaporin-4, the spray
Aquaporin-4 arranges that the intake tunnel 3 is connected with spray aquaporin-4, the spray aquaporin-4 packet along the radial direction of mushroom head shank 2
Upper wall, lower wall and two side walls are included, the distance between described upper lower wall gradually becomes smaller from inside to outside, between described two side walls
Distance become larger from inside to outside.
Mushroom head shank 2 is in cylindrical type, and the intake tunnel 3 is arranged along the axial direction of mushroom head shank 2, intake tunnel 3
Quantity is set as 1, and entire mushroom head shank 2 is made to become cylindric.The mushroom head head 1 includes a round end cap 5, the end
Lid 5 is fixed on the upper end of mushroom head shank 2, and the lower section of the end cap 5 is equipped with lower baffle plate 6, and the lower baffle plate 6 is fixed on mushroom head
On shank 2, fixed between the lower baffle plate 6 and end cap 5 there are two side baffle 7, the end cap 5, lower baffle plate 6 and two side blocks
