Closing time: turn-off time 1:9；When there is dust entrance in air duct, the output voltage U of infrared receiving tube is greater than the first setting electricity
Press U1,It is less than U simultaneously0When, the L1LED and L2LED of controller control at this time is lighted simultaneously, while the duty ratio of controller output is
3:7, i.e., the described controller control battery pack are the closing time of the switch of motor feed circuit: turn-off time 3:7；It is hot
The output voltage U of outer reception pipe is less than the first setting voltage U1, the simultaneously greater than first setting voltage U2When, controller controls at this time
L1LED and L2LED and L3LED are lighted simultaneously, while the duty ratio of controller output is 4:6, i.e., the described controller controls battery
Packet is the closing time of the switch of motor feed circuit: turn-off time 4:6；When the output voltage U of infrared receiving tube is less than
Two setting voltage U2, simultaneously greater than third setting voltage U3When, controller controls L1LED and L2LED and L3LED and L4LED at this time
It lights simultaneously, while the duty ratio of controller output is 5:5, i.e., the described controller control battery pack is motor feed circuit
The closing time of switch: turn-off time 5:5；Voltage U is set when the output voltage U of infrared receiving tube is less than third3, while it is big
Voltage U is set in the 4th4When, the L1LED and L2LED and L3LED and L4LED and L5LED of controller control at this time is lighted simultaneously, together
When controller output duty ratio be 7:3, i.e., when controller control battery pack is the closure of switch of motor feed circuit
Between: turn-off time 7:3；When the output voltage U of infrared receiving tube is less than the 4th setting voltage U4, controller controls at this time
L1LED and L2LED and L3LED and L4LED and L5LED and L5LED are lighted simultaneously, while the duty ratio of controller output is 9:
1, i.e., the described controller control battery pack is the closing time of the switch of motor feed circuit: turn-off time 9:1, in this way, i.e.
Can according in air duct amount of dust number, come automatic control motor work.
