Air filter structure
First Claim
1. An improved air filter structure, comprising:
- a container for containing a liquid;
a housing for covering the top of said container;
an air passage for letting air flow in and out of said container;
a motor being installed in said housing with its core axle facing the liquid in said container, and said core axle further comprising a fan, a stirring rod disposed at the bottom of said fan and dipped into the liquid in said container, and a control switch for controlling the rotation of said motor;
wherein a liquid selected from the collection of a plant liquid and an aromatic liquid being disposed in said container, and said fan producing an air circulation to bring the air from the outside of said housing into said container, and discharge the air in the container out of said housing by said air circulation, thereby the air outside said housing being circulated in and out of said container and liquid molecules contained in said container being discharged quickly to fill a room with fragrance, and while said fan producing an air circulation, said stirring rod stirring the liquid in said container as said fan rotates, and thus improving the activity of liquid molecules to accelerate the dispersion of liquid molecules and the contact of air entering said container from the outside of said housing with the liquid surface and attach the dust originally mixed in the air onto the liquid surface, and the dust sinking to the bottom of said container due to gravitation, and thus achieving the effect of filtering the impurities in the air, characterized in that;
a plurality of sensors, being disposed at appropriate positions of said housing and coupled to a control switch;
thereby when a person approaching the sensing range of said sensor, said sensor turning on said control switch to start said motor, and thus achieving the effect of filtering air.

Abstract
The present invention discloses an improved air filter structure, comprising a container, a housing covering the container, a motor, a fan, and a stirring rod disposed at the bottom of the fan. A plant liquid or an aromatic liquid is placed in the container, and the gas outside the housing circulate continuously in and out of the container by the fan, such that the molecules of the liquid in the container can be released quickly to fill the space of a room with fragrance. A plurality of sensors is disposed at appropriate positions of the housing, and connected to a control switch. When someone is approaching the sensing range, the sensor will turn on the control switch and start the motor, so that the fan will circulate the airflow, and the stirring rod will stir the liquid to accelerate the dispersion of the liquid molecules. The air entering the container will be in touch with the surface of the liquid, so that the dust originally mixed in the air will be attached on the surface of the liquid and sunk to the bottom of the container by gravitation, and thus achieving the effect of filtering the impurities in the air.
