Abstract: An ionic wind purifier is described. The ionic wind purifier includes a generating electrode and a collecting electrode, which are arranged oppositely. A potential difference exists between the generating electrode and the collecting electrode, and at least one first projecting part is arranged on each collecting electrode plate of the collecting electrode. The first projecting part has a smooth surface. Thus, by arranging the first projecting part, the adsorption area of the collecting electrode is increased and the absorption capability of the collecting electrode is improved, thereby improving the purification efficiency of the ionic wind purifier and improving the use performance thereof. A discharge monitoring and protective circuit of a high-voltage ion purifier is also described.

Abstract: A high-voltage protection device for an ionic wind purifier is described, which includes a micro switch (1) and a contact point (2) matching with the micro switch (1). The micro switch (1) and the contact point (2) are connected in series on a main circuit. Either the micro switch (1) or the contact point (2) is located on an inner side of a door cover (2) of the ionic wind purifier and the other one is located on a contact part of a main body and the door cover (3). The high-voltage protection device can automatically cut off a power source when a door of the ionic wind purifier is opened, so as to ensure the safety of a user. An ionic wind purifier including the high-voltage protection device is also described.

Abstract: Described is an ion air purifier. The ion air purifier includes a collector module (1) and a repeller module (2) which are connected in an openable and closable manner, wherein several collector plates (11) are uniformly distributed on the collector module (1), and several repeller plates (21) are uniformly distributed on the repeller module (2); and each collector plate (11) and each repeller plate (21) are alternately arranged when the two plates are in a closed state. Thus, an optimized distance between adjacent collector plates (11) and repeller plates (21) is ensured; and when the collector module (1) and the repeller module (2) are in an opened state, the collector plates (11) are separated from the repeller plates (21), and the distance between two adjacent collector plates (11) and the distance between two adjacent repeller plates (21) are both increased, thereby facilitating cleaning of the collector module. Further described is a network air purifier.
