Embodiments of the invention

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1 to FIG. 3, the embodiment is implemented as follows. A shared negative grid air filtering device includes a device body 1, a fan 2 located in the device body, a filter paper 3, a positive grid 4, and a negative The grid 5 is divided into a left filter paper 31 and a right filter paper 32, and the negative grid 5 is also divided into a left negative grid 51, a medium negative grid 53 and a right negative grid 52, and the positive grid 4 is divided into The left positive power grid 41 and the right positive power grid 42 are located between the left positive power grid 41 and the right positive power grid 42, and the left positive power grid 41 and the right positive power grid 42 are located on the left filter paper 31 and Between the right filter papers 32, the left negative power grid 51 and the right negative power grid 52 are respectively located outside the left filter paper 31 and the right filter paper 32, and the three peripheral edges of the positive power grid 4 and the medium negative power grid 53 are respectively provided. 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 inside of the air outlet 11 corresponds to the left negative power grid 51 and the right negative power grid 52. When the common negative grid air filtering device starts to operate, air is drawn into the air inlet 45 by the fan 2, and the air inlet 45 is provided with a closing block 456 on both sides and sides, and the air to be treated After entering, it is blocked by the three face closing gears 456 and then turned 90 degrees to move to both sides. The wind pressure of the air to be treated is continuously pressed by the air inlet 45, and the air to be treated starts to pass through the filter paper 3, in the air to be treated. The impurities are blocked on the inner side by the filter paper 3, and the air passing through the filter paper 3 becomes fresh air and then discharged through the hole of the negative power grid 5 and the air outlet 11, and in the process, the positive power grid 4 And the left and right negative power grid 51; 52 and the medium negative power grid 53 work to generate an electric field, and most of the bacterial viruses are electrically shocked to form impurities, which are also blocked by the left and right filter papers 31; 32, due to the filter paper 3, the positive power grid 4, and The negative grid 5 is installed in the apparatus body 1 in a vertical manner, which reduces the volume of the apparatus body 1, that is, reduces the thickness thereof, and both the left filter paper 31 and the right filter paper 32 can be filtered.
