Technical field
The utility model relates to a kind of negative ion generating circuit, specifically, relates to a kind of negative ion generating circuit of anti-electromagnetic interference.
Background technology
Mostly the circuit that existing anion generator adopts is by high-voltage tip discharging, thereby ionized air produces negative oxygen ion.Although sort circuit can produce negative oxygen ion, but there is following defect: 1. circuit High voltage output partly exists the positive potential of inducting, can offset a part of negative high voltage, anion-generating capacity is reduced; 2. the high-voltage pulse that circuit produces can produce electromagnetic interference to other electrical equipment that using in same circuit, affects electrical equipment and normally works; 3. when ionized air produces anion, also produced ozone.
Summary of the invention
The utility model exists and inducts positive potential and have the defects such as ozone generating and a kind of negative ion generating circuit of anti-electromagnetic interference is provided the electromagnetic interference of power supply, transformer secondary output for existing anion generator circuit just.
To achieve these goals, the utility model is realized by following scheme: a kind of generator circuit that can produce anion, comprises an anti-interference capacitor, low tension loop, transformer, high tension loop.It is characterized in that power input anti-interference capacitor C1 in parallel, low tension loop, high tension loop is connected with low tension loop by transformer T1; Described low tension loop is connected successively by the anode A of R2, D3, controllable silicon SCR, the control utmost point G of controllable silicon SCR is connected with resistance R 1, the negative electrode K of controllable silicon SCR with D1, transformer T1 is elementary is connected, one end of capacitor C 2 is connected with the anode A of controllable silicon SCR, and the other end is connected with transformer T1 is elementary.The electromagnetic interference that anti-interference capacitor C1 produces for eliminating high-voltage pulse; At a transformer secondary output high voltage rectifier in parallel, for eliminating the positive potential of inducting of High voltage output part, stable negative high pressure; The negative terminal that the carbon fiber bundle (or active carbon) that produces anion in order to ionized air is serially connected in to high-voltage capacitance carries charging current and negative high voltage in high-voltage charging circuit, improves negative oxygen ion generating capacity.Carbon fiber bundle (or active carbon) does not have point discharge simultaneously, without ozone occurs.
The beneficial effects of the utility model are, after adopting this negative ion generating circuit, can effectively eliminate the electromagnetic interference to power supply; The positive voltage of inducting that suppresses High voltage output part, the generating capacity of stable negative oxonium ion; Pencil carbon fiber (or active carbon) does not have point discharge not produce ozone.
Accompanying drawing explanation
Fig. 1 is the utility model circuit.
Embodiment
According to annexation between components and parts in the each several part circuit described in accompanying drawing and summary of the invention, and the components and parts technical parameter indicating in accompanying drawing requires to implement to realize the present invention with circuit production main points, below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, after switching on power, by R2, D3, D1, forming charge circuit charges to C2, now controllable silicon SCR is off state, when simple alternating current commutation, and SCR conducting, capacitor C 2 is through the elementary electric discharge of transformer T1, T1 time level is boosted C3 is charged, and carbon fiber bundle (or active carbon) 1 is serially connected in the negative terminal of high-voltage capacitance C3, carries charging current and negative high voltage in charging circuit.Carbon fiber bundle (or active carbon) 1 ionized air, produces negative oxygen ion.At power end anti-interference capacitor C1 in parallel, absorption may cause dry high-voltage pulse of scratching to power supply.At T1 level of transformer high voltage rectifier D5 in parallel, can effectively eliminate the positive potential of inducting of T1 level, on carbon fiber bundle (or active carbon) 1, form stable negative high voltage, the generating capacity of stable negative oxonium ion.
