BACKGROUND OF INVENTION 
     1. Field of the Invention 
     The present invention relates generally to the technical field of anion generating device product and method, and more particularly to an anion fall generating device and method. 
     2. Description of Related Art 
     The aero-anion is also known as “air vitamin”, which can improve human lungs, promote metabolism, enhance resistance to diseases and regulate central nervous system. The negative oxygen ions of small particle size are likely to act on medical care through human blood-brain barrier. The scientific research indicates that the content of anion in the air is an important factor which determines air quality. An amount of anions in the air not only removes dust, eliminates bacteria and purifies air efficiently, but also activates the oxygen molecules in the air to form oxygen-carrying anions. The anions exist everywhere in nature, such natural phenomena as thundering and lightning, photosynthesis of plants and waterfall impact can generate a lot of anions. 
     As the aero-anions are beneficial to human health, the anion generator occurs, which has been used in many electric appliances. In terms of conventional anion generator, the pulse-generating circuit of anion generator boosts the low voltage to DC negative high voltage through the high voltage module, the electrode tip generates negative DC high corona continuously, a lot of electrons (e−) are emitted at a high speed, but the electrons cannot exist in the air for long, they are caught by the oxygen and nitrogen molecules in the air immediately, so as to form aero-anions. The operating principle is coincident with the anion generation by natural phenomenon “thundering and lightning”. 
     The anion generator can generate aero-anions, but the generated anions are likely to be neutralized by the positive charges in the air, so their lifespan is limited, and the propagation distance is limited. Therefore, the range of use of the present anion generators is limited, failing to form an anion fall. If the distance is too long, the effect of anions is very limited. 
     On the other hand, the humidifier is a device for atomizing moisture. According to the atomization methods, the humidifiers are classified into direct evaporation humidifier, ultrasonic high frequency oscillation humidifier and so on, the moisture is atomized to fine particles, so as to increase the air humidity. 
     This inventor overcomes the defects in the existing anion generators, combines humidifier with anion generator through continuous research and development, and proposes the following technical proposal.
