Further, further include water supply device, the water supply device be provided in upper tower body and circle distribution it is multiple
Atomizer.
It further, further include annular steam line, annular steam line is provided with the opening towards annular insufflation channel,
Annular steam line is connect with pressure air source.
The utility model has the following beneficial effects:
Arranged for interval forms annular insufflation channel between upper tower body lower port and lower tower body upper port, can prevent powder from accumulating
It in the junction inner wall of upper tower body and lower tower body, and can be blown by blower duct to annular insufflation channel, to clean inner wall
The powder of accumulation.
