An air filter with a suspended power grid comprises a filter frame and a grid bottom frame. A piece of filter paper is disposed inside the filter frame. The filter frame is connected to the grid bottom frame in a fitting manner. The grid bottom frame is disposed above an air outlet of a purifier. An air flue support plate is disposed at the upper end of the air outlet. A positive electric wire is disposed below the filter paper. A lower discharge grid is disposed below the positive electric wire. The positive electric wire is mounted on a positive electric assembly. The positive electric assembly is fixedly mounted on the air flue support plate by using an insulation support column. The lower discharge grid is fixed on the air flue support plate by using the support column. An accident that a positive electric wire is ignited with a lower discharge grid by means of dust impurities is effectively prevented when a product works, thereby avoiding a potential safety hazard. The periphery of the lower discharge grid does not contact a grid bottom frame, and is connected below an ion wire assembly by using a support column, so that no place is available for ignition of high-voltage electricity, and the use safety of a device is improved. |
