The plasma and anion purification device has relatively good oil fume purification effect, the plasma device has the problem of ozone generation in a working chamber, the damage to human health and household appliances is large, and the process of reversely removing the ozone is large in a lot of trouble; the anion air purifier is more and more optional. Scientific experiments prove that the negative ions can rapidly neutralize the coke smoke, 'second-hand smoke', oil smoke and floating dust which belong to the positive ions in the air, and the air structure is improved.

Some negative ion air purification equipment on the market at present mainly have following some problems:

1. part of the negative ion equipment generates static electricity, which causes damage to peripheral equipment and parts and has potential safety hazard.

2. Some negative ion devices are mainly used for generating negative ion wind, charges tend to move towards objects with potential differences on the periphery, and the negative ions promote the aggregation and precipitation of pollutants and often cause the pollutants attached to the purifying devices and peripheral walls to blacken, so that secondary pollution is generated.

3. After the negative ion equipment enables the peripheral objects to carry static electricity, if the static electricity cannot be effectively released, the potential difference between the electrode and the peripheral objects is reduced, and the negative ions emitted by the electrode are also greatly reduced.

4. Static electricity is released by a part of negative ion air purifiers through zero connecting lines, so that a negative ion electric field and other lines in the purifier form a loop in the actual working process, a plasma-like effect is generated, and ozone pollution is generated.

How to more effectively control and utilize the anion, improve its purification efficiency to make good use of the strong points and avoid the weak points is the matter we need to do, therefore, it is necessary to provide a novel grounding anion air purifier to solve the above technical problems.
