Description
Technical field
The utility model belongs to electronic applications, refers in particular to a kind of air purifier of automatic adjusting ozone concentration.
Background technology
Air pollution is in recent years more and more serious, and it has been a kind of luxurious particularly can breathing ozone metropolitan people.In order to change this present situation, some families with good conditionsi buy air purifier one after another.For air purifier, the air purifier that really can remove aerosol (PM2.5) has generally all adopted electrostatic precipitator technology.Inevitably like this can produce ozone.A small amount of ozone can sterilization, useful to human body, and excessive ozone stimulates respiratory tract, causes people's respiratory disorder.Thereby the ozone concentration of generation is controlled in rational scope, be to ensure that air purifier does not bring the precondition of the negative injury of people.The ozone concentration of air purifier is fixed at present, exceeds standard because accumulation can make part.The effective electrostatic potential that requires of electrostatic precipitation is high, and the corresponding ozone concentration producing is just large; Otherwise little.In fact, dust removing effects and ozone concentration are conflicts.If can adjust high-pressure electrostatic voltage according to ozone concentration, under the condition that can ensure not exceed standard at ozone, produce sufficiently high high-pressure electrostatic voltage, thereby reach best dust removing effects.The utility model proposes a kind of air purifier of automatic adjusting ozone concentration, it can regulate ozone concentration effectively for this reason.
Summary of the invention
For the ozone concentration that can automatically regulate air purifier to produce, make it not exceed standard, the utility model proposes a kind of air purifier of automatic adjusting ozone concentration.
The utility model solves the technical scheme that its technical problem adopts: the utility model device is by ozone sensor, high-voltage positive electrode plate, high voltage negative plate, filter material layer, circuit box, air purifier casing, single-chip microcomputer, high-tension transformer, triode, resistance, air-introduced machine composition, it is characterized in that: columniform ozone sensor, high-voltage positive electrode plate, high voltage negative plate, air-introduced machine, circuit box, filter material layer is all in the air purifier casing of cuboid, filter material layer is positioned at the outside of air purifier casing, high voltage negative plate is positioned at the rear of filter material layer, high-voltage positive electrode plate is positioned at the rear of high voltage negative plate, ozone sensor is positioned at the back upper place of high-voltage positive electrode plate, air-introduced machine is positioned at the rear of high-voltage positive electrode plate, circuit box is positioned at the rear of high-voltage positive electrode plate, ozone sensor is connected with single-chip microcomputer, and high-voltage positive electrode plate and high voltage negative plate, by high-tension transformer, triode, resistance, are connected with single-chip microcomputer.
High-voltage positive electrode plate, high voltage negative plate, filter material layer and air purifier casing are cuboid.Ozone sensor is cylindrical.
Air, under the effect of air-introduced machine, is entered by filter material layer, and the gas after the filtration of the bed of material enters the further dedusting of high voltage electric field being made up of high-voltage positive electrode plate and high voltage negative plate after filtration, then discharges through air-introduced machine.In the process of high voltage electric field dedusting, can produce a large amount of ozone, the diffusion meeting of ozone in gradient.Because accumulation can cause, apart from electric field, concentration is the highest nearby, and therefore an ozone sensor is installed after electric field.It can monitor the maximum concentration of ozone.
Ozone sensor operation principle is: ozone and other gases are diffused on induction electrode by diffusion barrier.Control circuit maintains a voltage that is enough to start chemical reaction between at induction electrode with to electrode, and the electrochemical reaction producing under the effect of ozone forms electric current between the two poles of the earth.The intensity of this electric current and the concentration of ozone are proportional, and are reversible.Control circuit also forms bias level in induction pole with between to electrode, and this level does not form electric current between the two poles of the earth, and the fast reaction of sensor makes it can carry out to surrounding air the detection of real-time continuous.Ozone sensor of the present utility model adopts O3/C200.
Ozone sensor changes the signal monitoring the signal of telecommunication into and is sent to single-chip microcomputer, and single-chip microcomputer allows highest standard value to compare with the ozone country prestoring in internal memory the ozone value of sending into.Allow highest standard value if the ozone concentration monitoring is less than country, single-chip microcomputer sends without instruction; If the ozone concentration monitoring allows highest standard value higher than country, single-chip microcomputer sends instruction, the frequency that reduces port output pulse, changes pulse width, and pulse width is increased, by the conducting of resistance control triode with increase by the time, thereby the lower voltage that the connected step-up transformer of transistor collector is produced, secondary voltage also declines thereupon, causes Electrode voltage drop, ionization voltage declines, and ozone concentration declines thereupon.So far completed the automatic adjusting of ozone sensor to air purifier.
The beneficial effects of the utility model are that the ozone concentration that can automatically regulate air purifier to produce, makes it not exceed standard; Make air purifier reach the optimum efficiency of dedusting simultaneously.It is mainly used in electrostatic precipitation field.
