Air -inlet grille and air treatment equipment

The utility model discloses an air -inlet grille and air treatment equipment, several arc air inlet portion on air -inlet grille includes the arc and locates the arc, arc air inlet portion arranges along the circumference direction of arc in proper order, and the arc is made by plastic materials, and every arc air inlet portion includes the several fresh air inlet, and the axial direction of all fresh air inlets of same arc air inlet portion is the same, the tangential direction of this air inlet portion intermediate position of the axial direction perpendicular to of the fresh air inlet of each arc air inlet portion. The utility model discloses an air -inlet grille and air treatment equipment makes arc, effective reduction in production cost through plastics to set up array arc air inlet portion on the arc, simultaneously set up the axial direction of the fresh air inlet in the air inlet portion for the tangential direction of the intermediate position of this air inlet portion perpendicularly, so that the air inlet orientation of each arc air inlet portion all towards the intermediate position of arc, avoids the fresh air inlet to the sheltering from of not equidirectional wind, effectively guaranteed the intake.
