Air purifier with air guide grating device

Abstract

The invention relates to an air purifier with an air guide grating device, and belongs to the technical field of air purifiers. The air purifier comprises a purifier shell with an air inlet and an air outlet and an air purification device arranged in an inner cavity of the purifier shell; an air inlet and an air outlet of the air purification device are communicated with the air inlet and the air outlet of the purifier shell respectively, air outlet gratings are arranged at the air outlet of the air purification device through a grating groove, the air outlet gratings and the grating groove are hinged through a hinge shaft, and the grating groove is communicated with the air outlet of the air purification device and is fixedly welded to the position above the air outlet of the air purification device. The air outlet gratings and the grating groove are buckled through the hinge shaft, the air outlet gratings are driven by a synchronous motor to turn over vertically, the air outlet direction is changed into the front upper direction from the vertical upward direction, the air feeding distance is increased, the purification effect is improved, and dust falling on an air flue can be prevented.

Description

technical field [0001] The invention belongs to the technical field of air purifiers, in particular to an air purifier with a conduction grille device. Background technique [0002] Most of the current air purifiers use the upward air outlet mode, and its main structure is composed of a forward-leaning centrifugal impeller, a volute, and an air outlet grille. The air outlet uses the grille to directly supply air upwards. The air guide structure of this structure has the following disadvantages: 1. For a purifier with a large air volume and a large height, because the overall height of the fuselage is high, the air outlet is close to the ceiling of the room, and the direct air supply from the grille will cause the air to flow from the purifier. After coming out, blow to the ceiling at a vertical or near vertical angle. This will cause poor air supply, which is not conducive to the effective circulation of air in the room, will reduce the purification effect, and direct blowi...
