Anion-generating device

An anion-generating device, which includes:

• a shell body, in which there is an accommodation space, and on which an air inlet and an exhaust outlet are arranged for facilitating the outside air to enter the device, go through the ionization procedure operated in the accommodation space, and leave the exhaust outlet again;
• at least an ion-generating module, which is arranged in the accommodation space, and which includes:
• a first electrode portion, which is located at the adjacency of the air inlet and is connected to a high-voltage power source;
• a second electrode portion, which includes at least two electricity conductive plates, and which is located at the adjacency of the exhaust outlet, and the ion-generating module may charge and ionize the air particles that are flowed from the first electrode to the second electrode;
• and
• a controlling device, which includes:
• a logic controlling circuit, which may control the electric action of the anion-generating device and may automatically shut off the ionization action executed on the air by the ion-generating module when there is a short circuit occurred in the first electrode portion and the second electrode portion;
• a high-voltage power-source generating circuit, which is connected to the logic controlling circuit and receives the control coming from the logic controlling circuit to thereby generate a high-voltage power source needed by the first electrode.
