Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
Embodiment 1
As shown in figures 1 to 6, a kind of dismountable air inlet device, including being fixedly mounted on fan body A air inlet
Outside air door 1, be fixedly connected on the pressure ring 2 outside air door and be fixedly connected on the aspiration channel 3 outside pressure ring；
Described air door 1 includes Inlet Network 11 and the first installation sheet 12 extended along Inlet Network outer peripheral edge, the first installation sheet 12
On offer several internal ring fixing hole 121 for fixedly mounting pressure ring and several for air door is fixedly mounted on blower fan this
Outer shroud installing hole 122 outside body air inlet；Described first installation sheet and Inlet Network junction projection one annular flange flange 123, institute
Stating pressure ring is annular, and pressure ring is set in the periphery of annular flange flange.The pressure corresponding with internal ring fixing hole position is offered on pressure ring 2
