It is integrated.
Connecting seat is provided with position of the madial wall to blade fixing hole of described wheel disc, connecting seat is provided with and leaf
The screw that piece fixing hole communicates, the upper end of screw are provided with the accommodating cavity of accommodating screw terminal.
Described blade includes connecting portion and lodicule, and blade and axially setting in a certain angle, described lodicule are curved
Structure, the width of lodicule become larger from bottom to up；The honeycomb duct of shape face half-closed type between lodicule and wheel disc outer wall.
The utility model blade and wheel disc separation, blade use the lodicule structure of arc, so can be in lodicule and wheel disc
The honeycomb duct of shape face half-closed type between outer wall, be advantageous to be lifted the height of spray, so as to lift oxygenation efficiency；This other practicality is new
Type is provided with limbers or outlet pass on the inwall of fixed seat, occurs after solving impeller work a period of time inside and outside due to impeller
Draught head and cause oxygenation efficiency decline the problem of.
Motor and decelerator are connected directly between on the connecting portion on the outside of fixed seat, and connecting portion extends to from wheel bottom
Top, intensity greatly reinforce, and it is more convenient to assemble and connect.
