Further, the tapered body in the lower end of the outer wall is provided with conical seat in the inner cavity of the lower part of outer wall, bores The top of shape seat is fixedly connected with the bottom of mixer, has the second cavity between conical seat and outer wall, runs through the second of outer wall Air inlet is connected to the second cavity;Conical seat is internally provided with fluid channel in the axial direction, the upper end of fluid channel and the The lower end of two gas-liquid mixed rooms is connected to, the lower end face nozzle of fluid channel, and sizing material is noted after flowing through conical seat with the second air inlet The compressed gas entered is mixed to form rotation direction turbulent flow in the cone space that conical seat bottom, outer wall form.
Further, first gas-liquid mixed room is connected to the lower end of the first stomata, the upper end of the second stomata and adjusting The first cavity connection between set and outer wall.
Further, first stomata is identical as the angle of inclination of the second stomata.
Further, the width of first gas-liquid mixed room is more than the width of the second gas-liquid mixed room.
Further, it is fixed with sealing ring between the upper part and outer wall of the conical seat.
Further, the nozzle is arranged in inverted funnel shape.
Beneficial effects of the present invention:
The present invention can use heat resistance preferable but the higher self-styled sizing material of shear viscosity, and the present invention can make full use of self-styled The shear shinning effect of sizing material itself, bubble can be reduced using turbulent flow caused by the injection of rotation direction step by step and nozzle rotation direction air-flow The viscosity that self-styled sizing material flows in the showerhead reduces obstruction risk.Simultaneously because nozzle uses effervescent atomization mode, nozzle inside diameter And hydraulic system pressure can reduce, and reduce the risk of nozzle damage, nozzle is not easy obstruction damage.
