It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-6, the present embodiment provides a plasma electric fan comprising: fan head 1, fan seat 2, damping piece and plasma generator 4. Wherein the fan head 1 can fan air in a designated direction. The plasma generator 4 is connected to the fan head 1.

The plasma generator 4 is an existing device, and has a main operation principle that a low voltage is boosted to a positive high voltage and a negative high voltage through a booster circuit, and air (mainly oxygen) is ionized by the positive high voltage and the negative high voltage to generate a large amount of positive ions and negative ions, wherein the amount of the negative ions is larger than that of the positive ions. The positive ions and the negative ions generated by the plasma generator simultaneously generate huge energy release at the moment of neutralizing positive and negative charges in the air, so that the structure of bacteria around the plasma generator is changed or the energy is converted, the bacteria are killed, and the sterilization effect of the plasma generator is realized. Because the quantity of the negative ions is greater than that of the positive ions, the redundant negative ions still float in the air, and the effects of eliminating smoke and dust, eliminating peculiar smell and improving the quality of the air can be achieved, so that the health care effect of human health is promoted.

The plasma generator 4 is connected to the fan head 1. The plasma generator 4 can ionize air to form positive and negative charged particles, the positive and negative charged particles have the effects of sterilization and deodorization, and the positive and negative charged particles can be diffused into the surrounding environment along with blown wind, so that the environment is sterilized and deodorized.

The damping member is used to connect the fan head 1 and the fan base 2. The resistance of the fan head 1 and the fan seat 2 to overturn is increased. Therefore, when the fan head 1 is pushed by force, the resistance provided by the damping piece can be overcome, so that the fan head 1 can turn back and forth relative to the fan seat 2. When the pushing force to the fan head 1 is cancelled, the resistance provided by the damping piece prevents the fan head 1 from being fixed relative to the fan seat 2 by turning back and forth, namely, the fan head 1 is suspended at the position.

When the fan head 1 is used, if the fan head 1 has different angle requirements, the fan head 1 can be turned to a proper angle by pushing the fan head 1 with force. Then the fan head 1 is loosened, and the fan head 1 is suspended and fixed at a proper angle under the action of the damping piece. So set up, the user can be according to the angle of demand adjustment fan head 1 to adjust suitable direction of blowing, use and experience better.
