The position one-to-one locating notch of flange, is provided with back-up ring at the outer ledge of the protection network.Positioning flange, on the one hand increase connects
The intensity of narrow bars itself, on the other hand play positioning action when protection network is installed so that protection network and the spiral shell on spiral case
Pit being capable of quick alignment；Back-up ring plays sealing function to the edge of activated carbon filter component, prevents oil smoke tail gas from activity
The edge of charcoal filter assemblies enters in inlet chamber.
Preferably, the middle part of blade is provided with reinforcing ring, each blade both passes through reinforcing ring.Due to length of blade compared with
Greatly, larger by blast when impeller assembly rotates, reinforcing ring can increase the intensity of blade, prevent deformable blade.
Preferably, described air channel is twist distributed in spiral case, the axial width in the air channel is equal everywhere, institute
The radial width in air channel is stated from air intake to increasing successively.The air channel of this kind of structure, air-flow formation can be prevented to be vortexed, be turbulent,
Flow backwards so that exhaust is more stable, smooth, moreover it is possible to reduces noise.
Therefore, the present invention, which has, to have to oil smoke tail gas progress double filtration, good filtration effect, overall performance stabilization
Beneficial effect.
