  • the left negative grid and the right negative grid each adopt an open-cell metal plate.
  • the positive power grid is connected to circuitry provided in the body of the apparatus.
  • the shared negative grid air filtering device reduces the volume of the device body because the filter paper, the positive power grid and the negative power grid are installed in the body body in a vertical manner. That is to say, the thickness thereof is reduced, and both the left filter paper and the right filter paper can function as a filter, and then the clean air is discharged outward, so that the air filtration efficiency is greatly improved, and the negative grid is spaced from the positive grid.

  • the closing block 456, the other periphery of the positive power grid 4 and the medium negative power grid 53 is the air inlet 45, that is, the side of the positive power grid 4 and the medium negative power grid 53 without the closing gear are combined to form the
  • the air inlet 45 increases the area of the air inlet 45 and increases the air intake amount, and the air inlet 45 is connected to the air outlet of the fan 2,
  • the four peripherals of the left filter paper 31 and the right filter paper 32 are respectively provided with a closed enclosure, which mainly serves to prevent the internal air to be treated from leaking to other parts of the body, and the air outlet 11 is disposed on both sides of the apparatus body 1.

  • the right positive grid 42 and the right negative grid 52 form another electric field for sterilization, which is equivalent to the effect of two grid filtering devices, but only uses a medium-negative grid 53.
  • This design mainly considers the increase of the inlet 45. After that, the problem of the distance between the positive and negative grids cannot produce a good electric field. This design is greatly reduced in terms of material cost and energy consumption cost.
  • the positive power grid 4 is horizontally disposed on two vertical closing gears 456, and the bending lines of the left and right filter papers 31; 32 are disposed perpendicular to the horizontal plane to uniformly set the electric field.
  • the bending lines of the left and right filter papers 31; 32 are horizontally disposed, and the inner bending lines of the filter paper 3 are aligned with the ion lines of the positive power grid 4, so that the filter paper 3 can be caused.
