Description
Technical field
The utility model relates to a kind of power supplier, particularly relates to a kind of power supplier of air cleaning filter.
Background technology
Air purifier kind has a lot, have desk-top, vertical and wall-hanging, also have the air intlet position being contained in indoor apparatus of air conditioner, air conditioner is all generally within 24 hours, switch on power, with lever operated open and close, if air purifier is also switch on power for a long time, just also want within 24 hours, be energized, even if air-conditioning does not use, air purifier is also in work, waste valuable electric power energy like this, also can accelerate the aging of electrostatic precipitation filter.
Utility model content
The utility model object is to overcome prior art deficiency, adopts a kind of current transformer principle, and when realizing only having air conditioner to operate, air purifier could obtain power supply.
Solving the problems of the technologies described above adopted technical scheme is: a kind of power supply adaptor of air purifier, comprise shell, electronic circuit board, current transformer and low-tension supply plug, it is characterized in that: described shell is made up of upper shell and lower house, lower house is equipped with attaching plug, upper shell is equipped with supply socket, there is a low-tension supply line outlet side of lower house, is provided with electronic circuit board summation current transformer in shell, described electronic circuit board bag is provided with transformer isolation circuit, capacitance-resistance voltage reduction circuit and electronic switching circuit, introduce connection transformer buffer circuit after the attaching plug series current instrument transformer primary circuit of power supply and electronic switching circuit, transformer isolation circuit connects capacitance-resistance voltage reduction circuit, so, 220 volts of alternating currents through isolation become direct current 12 volts through capacitance-resistance voltage reduction circuit, be connected to low-tension supply plug, export 12V DC, the secondary circuit of described current transformer is connected to the control end of electronic switching circuit, when after air conditioner work, the control end unlocking electronic switching circuit of the current trigger electronic switching circuit that transformer secondary circuit produces, electronic switching circuit UNICOM is through the exterior power supply of current transformer and transformer isolation circuit, make adapter work, export 12V DC.
The beneficial effects of the utility model are:
1, structure is simply firm, easy to manufacture, with low cost;
2, adopt power supply adaptor of the present utility model, can automatically effectively start with the unlatching of indoor apparatus of air conditioner and stopping and closing the supply of air purifier power supply, electrical energy saving.
