Description
Technical field
The utility model belongs to electronic applications, refers in particular to a kind of air purifier filtration channel automatic transfer equipment.
Background technology
Recent medical research shows that the generation of lung cancer is in rising trend, and particularly the lung cancer incidence of non-smoker is in rising trend too.The appearance of existing this situation of bibliographical information is in close relations with PM2.5.PM2.5 refers to that aerodynamic diameter is less than the particle of 2.5 microns, and it can adsorb various noxious material and directly enter human body lower respiratory tract.Generally acknowledge now that PM2.5 is one of pollutant.
In order to tackle more and more serious air pollution, air purifier becomes the selection that people have no alternative, and also makes air purifier industry obtain development at full speed simultaneously.The air purifier of various pattern makes people dazzled, and their principle is basically identical, all needs through filter screen filtering dust particles.Filter screen work a period of time is approximately about 2 years, needs to change, otherwise will not have Air purification, also may bring negative effect due to the harmful substance such as attract dust and bacterium to health owing to adsorbing too much dust.Current filter screen needs artificial replacing.Owing to using air ambient different, replacing construction is also inconsistent, and the replacing of overfrequency causes waste, and excessively slow replacing filter effect is bad, even unhealthful.Filter screen dust removing effects after some adopt cleaning technique and automatic cleaning technology process will decline (be difficult to clean up, and may change the aperture of filter screen due to the impact of rinsing).The kind of screen pack has many, and most filter screen is hard net that can not be curling, and as HEPA, active carbon filter screen etc., they can not take curling mode to change the filter screen used.In order to realize the filter screen automatically changing air purifier, patent of the present invention proposes a kind of air purifier filtration channel automatic transfer equipment.It is by automatic air switching clarifier filtration channel, realizes the automatic replacing of air purifier filter screen.Filter screen is in air purifier filtration channel, and after air purifier filtration channel is changed, natural air clarifier filter screen has also just been changed.
Summary of the invention
In order to automatically can change the filter screen of air purifier in good time, the utility model proposes a kind of air purifier filtration channel automatic transfer equipment.
The utility model solves the technical scheme that its technical problem adopts: the utility model is by changing front filter screen, filter screen after changing, filter chamber before changing, filter chamber after changing, pressure sensor, air purifier casing, filter screen passage before changing, filter screen passage after changing, magnetic valve before changing, change rear electromagnetic valve, gas threeway, gas outlet channels, circuit control box, single-chip microcomputer, triode, resistance, air-introduced machine, relay forms, and it is characterized in that: before rectangular replacing, filter screen and columniform pressure sensor are before rectangular replacing in filter chamber, and after rectangular replacing, filter screen in filter chamber, changes front filter chamber after rectangular replacing, filter chamber after changing, filter screen passage before changing, filter screen passage after changing, gas threeway, gas outlet channels, circuit control box is all in rectangular air purifier casing, and before rectangular replacing, filter chamber is by changing front filter screen, filter screen passage before changing, magnetic valve before changing, gas threeway, air-introduced machine, is connected with columniform gas outlet channels, and after changing, filter chamber is by filter screen after replacing, filter screen passage after changing, change rear electromagnetic valve, gas threeway, air-introduced machine, is connected with columniform gas outlet channels, pressure sensor is connected with single-chip microcomputer, and before changing, magnetic valve and replacing rear electromagnetic valve are respectively by relay, triode, resistance, are connected with single-chip microcomputer.
Before changing filter screen with filter screen length after changing and thickness identical, thus ensure to change dust removing effects after filter screen and do not change.Before changing, the length of filter screen and the filter screen length after changing all are less than 1/2nd of the length of air purifier casing.
Before changing, filter screen is before replacing in filter screen passage, and after changing, filter screen is after replacing in filter screen passage; Complete the same replacing (completing filtration channel conversion) changing rear filter screen passage of filter screen passage before changing, namely complete and change the replacing (complete the replacing of filter screen) of front filter screen with filter screen after replacing.
The front filter screen of replacing, the rear filter screen of replacing, the front filter chamber of replacing, the rear filter chamber of replacing, air purifier casing are all rectangle, and gas outlet channels, the front filter screen passage of replacing, the rear filter screen passage of replacing, the front magnetic valve of replacing, replacing rear electromagnetic valve, pressure sensor are all cylindrical.
Air purifier is when newly using, under the effect of air-introduced machine, its air flowing access is for sucking by changing front filter chamber, through replacing front filter screen to air-filtering after, enter filter screen passage before changing, before the replacing of opening, magnetic valve arrives gas threeway, finally by by air-introduced machine, discharged by gas outlet channels, air is purified.
After a period of operation, before replacing on filter screen, by dust granules a large amount of for absorption, cause whole current path not smooth, before changing, filter room pressure increases air purifier.The pressure signal detected is sent to single-chip microcomputer by the pressure sensor before replacing in filter chamber.The signal that pressure sensor is sent into by single-chip microcomputer is compared with the pressure limit value prestored in single-chip microcomputer internal memory, if lower than pressure limit value, then single-chip microcomputer sends without instruction.Gas is still by the circulation of original path; If higher than pressure limit value, then single-chip microcomputer sends instruction, by resistance, triode, relay, disconnect the power supply of magnetic valve before changing, connect the power supply changing rear electromagnetic valve, before changing, magnetic valve will cut out under the action of the spring simultaneously, and changing rear electromagnetic valve will open.Now the path of gas will change into by change rear filter chamber suck, through replacing after filter screen to air-filtering after, enter change after filter screen passage, replacing rear electromagnetic valve through opening arrives gas threeway, eventually pass air-introduced machine, discharged by gas outlet channels, air is purified.Thus also complete the automatic replacing of filter screen.
The beneficial effects of the utility model are, automatically can change the filter screen of air purifier, to reach the optimum efficiency of dedusting in good time.It is mainly used in indoor dust removal field.
