As shown in Figure 2, the Multifunctional inflating device in the present embodiment comprises the steps:
Step a. operating personal is set mode of operation (fill air mode, inflated with nitrogen pattern, the pattern of leaking hunting, vacuumize pattern) by press key input device 15.After by the selected mode of operation of press key input device 15, the tire pressure value that each mode of operation is corresponding (when mode of operation when filling air mode or inflated with nitrogen pattern) or overcharge atmospheric pressure value (when mode of operation is that overvoltage is while leaking hunting pattern) and be shown on read out instrument 14, operating personal can or overcharge the size of atmospheric pressure value by "+" on key input apparatus 15, "-" button adjusting knurl air pressure value, thus the setting of the pattern of finishing the work.
Described controller 13 these mode of operations of judgement of step b. fill air mode, inflated with nitrogen pattern, the pattern of leaking hunting or vacuumize pattern;
Step c when this mode of operation be while filling air mode, the initial gas pressure value C1 measured according to described pressure sensor 10 and the tire pressure value S1 of setting calculate and fill air time t1, and then described controller 13 is opened the described air diverter valve 6 that fills and filled fast air.After elapsed time t1, described controller 13 cuts out the described air diverter valve 6 that fills, measure the atmospheric pressure value of a tire, atmospheric pressure value and tire pressure value S1 that controller 13 is measured described pressure sensor 10 compare, when this atmospheric pressure value is less than tire pressure value S1, described controller 13 is opened the described air diverter valve 6 that fills and is filled in short-term air, then described controller 13 cuts out the described air diverter valve 6 that fills again, measure again the atmospheric pressure value of a tire, and atmospheric pressure value and tire pressure value S1 that described pressure sensor 10 is measured compare, so circulation 1～5 time is until the atmospheric pressure value that pressure sensor 10 is measured in tire pressure value S1 scope the time, filling air completes, described controller 13 is controlled warning device and is sent alerting signal, when the atmospheric pressure value of described pressure sensor 10 mensuration is greater than tire pressure value S1, described controller 13 is opened described the first control cock 8 and is lost heart, until the atmospheric pressure value that pressure sensor 10 is measured is in tire pressure value S1 scope.
Steps d. when this mode of operation is the inflated with nitrogen pattern, the initial gas pressure value C2 that described controller 13 is measured described pressure sensor 10 and default atmospheric pressure value Y1 (default atmospheric pressure value Y1 is stored in memory device) compare.
When steps d 1. is less than or equal to this default atmospheric pressure value Y1 as this initial gas pressure value C2, now tire is too low without tire pressure or tire pressure, need first vacuumize, to avoid entrained air in tire.Described controller 13 is opened described the first control cock 8 and the second control cock 9 starts to vacuumize, simultaneously described controller 13 receives the real-time atmospheric pressure value that described pressure sensor 10 is measured, and this real-time pressure value is compared with default default atmospheric pressure value Y2, when this real-time atmospheric pressure value is in default atmospheric pressure value Y2 scope, vacuumized, described controller 13 cuts out described the first control cock 8 and the second control cock 9, then enters steps d 3 and carries out inflated with nitrogen.
