The specific embodiment
See Fig. 2 and Fig. 5, a sensor (3) that detects dust amount is housed near air inlet (2), the sensor (14) that another detects dust amount is housed near gas outlet (15), its model is SHARP BP2Y1010; Input signal cable, output signal line and the power line of sensor (3) and (14) is connected with electronic circuit control plate (5) respectively, and wherein input signal cable connects respectively the I/O pin of the upper single-chip microcomputer of electronic control circuit plate (5); Output signal line connects respectively the input end of analog signal of the upper single-chip microcomputer of electronic control circuit plate (5); Single-chip microcomputer adopts C8051F410, and concrete mode of connection can be referring to the handbook of SHARP BP2Y1010 and C8051F410.Electronic control circuit plate (5) is connected with display screen (4) again, and display screen can be Multi-bit LED digital display screen, can be also LCD display, and method of attachment is referring to the data of relevant single-chip microcomputer application aspect.The utility model adopts the LED charactron of two groups of different colours to show respectively the dust amount of air cleaner air inlet and gas outlet, gives user an effect of understanding air cleaning directly perceived.Display screen is arranged on obvious position.Air inlet (2) communicates with the air inlet of blower housing (6); The air outlet of blower fan is taken over filtering material container (9), fills filtering material (17) in filtering material container (9), and filtering material (17) can adopt active carbon; In filtering material (17), also evenly put some PTC heating plates (10) as heater, the power supply of PTC heating plate (10) is connected with the heating control circuit of electronic circuit control plate (5), and heating control circuit can adopt single-chip processor i/o mouth to drive solid-state relay; Filtering material container (9) be respectively the netted cover plate (16) of breathing freely above and below, see Fig. 3.Being connected with airflow-reversing device (11) below of filtering material container (9), in airflow-reversing device (11), be provided with air flow guiding plate (13), its axle and reducing motor (12) shaft coupling, can make the air-flow that filtering material container (9) is blown down flow out from fresh air outlet (15) or waste gas outlet (18) by swirling eddy deflector (13).Operation principle of the present utility model is such: when blower fan is worked, room air will enter air cleaner from air intake (2), sensor (3) detects and shows entrance concentration of dust at display screen, air enters air filting material box (9), filter out dust, bacterium, after pernicious gas, enter airflow-reversing device (11), now air flow guiding plate (13) is by the air-flow fresh air outlet (15) of leading, sensor (14) detects and shows at display screen the concentration of dust that outlet (15) is located, if now room air is more dirty, the data that sensor (3) and sensor (14) record will have larger difference.If the data that sensor (3) and sensor (14) record are all larger, filtering material (17) inactivation is described, need regeneration to activate.The utility model adopts PTC heating plate (10) to filtering material (17) activation of regenerating, while air flow guiding plate (13) 90-degree rotation under the driving of reducing motor (12), by the air-flow waste gas outlet (18) that leads, waste gas outlet (18) is connected with pipeline, by outside waste gas discharge chamber.The startup that regeneration activates can be that user manually controls, the data that also can be recorded according to sensor (3) and sensor (14) by single-chip microcomputer are controlled automatically, while only having equally the dust data that record when sensor (3) to surpass setting value, the work that air cleaner just can start to purify air, to save power supply.Power supply in Fig. 5 is connected with electronic circuit control plate (5), for power supplies such as electronic circuit control plate (5) and motors, can adopt 5V+12V two-way 200W Switching Power Supply.
