The split timing function that is constituted with regard to above-mentioned split timing controlled circuit, overall timing controlled circuit and basic timing controlled circuit, overall timing function, basic timing function illustrate respectively below:

1, split timing function:

When using the split timing function, first clockwise direction rotation inner button 911 is indicated on the indication panel 10 time value (as being set at 30 minutes) accordingly, specifies overhead cam 7 travel times; Clockwise direction rotation outer knob 912 is specified the travel time (as being set at 20 minutes) of cam 8 down again; Promptly shown in B among figure working state schematic representation Fig. 6, wherein A is an initial condition.Counterclockwise regulation stall switch 92 is selected regularly gears (as being chosen to be 2 ' grade) of splits then; At last, rotate common gear speed regulator, the selected gear (as being chosen to be 3 grades) of working at the beginning.At this moment, fan electromotor is started working (promptly starting working from 3 grades), and just fan electromotor is connected working power by basic timing controlled circuit C.Because overhead cam 7 is to synchronous working with following cam 8, therefore when setting the travel time of overhead cam 7 and following cam 8, the travel time of overhead cam 7 must could be realized the split timing function greater than the travel time of following cam 8 again.Therefore the walk time value (using up in 20 minutes) of setting of cam 8 instantly, stop member 3 falls into down in the breach 83 of cam 8, conducting metal body 81 on the stop member 3 on conductive metal contact and the following cam 8 be electrically connected disconnection, promptly shown in C among figure working state schematic representation Fig. 6, the selected gear of common gear speed regulator quit work (promptly 3 grades quit work).At this moment, 7 of overhead cams walk on the remaining time (deducted 20 minutes and equal 10 minutes in promptly 30 minutes), conductive metal contact on the stop member 3 is under stop member 3 stiff end action of reset spring, connect with the conducting metal body 71 on the overhead cam 7, the selected split of driving switch 92 this moment is gears start working (be fan electromotor be transformed into 2 ' grade start working) regularly.Walked the remaining time (using up in promptly 10 minutes) up to overhead cam 7, because when using the split timing function, conductive metal contact 72 access failure electric currents in the breach 73 of overhead cam 7, therefore, when stop member 3 fell into the breach 73 of overhead cam 7, driving switch 92 was cut off power supply, promptly shown in D among figure working state schematic representation Fig. 6, also just get back to the initial condition shown in the A among Fig. 6, fan electromotor quits work.In whole split timing function from artificial setting intact after, entire work process need not artificial participation and finishes automatically.Realize the fluid drive of fan motor therefrom, thereby realize controlling at times automatically the effect of air output size, to satisfy of the requirement of different periods of people different wind speed.As a same reason, also can realize from " 1 ' grade-2 ' grade-stop "; " 1 ' grade-3 ' grade-stop "; Air-supply processes such as " 2 ' grade-3 ' grades-stop ", vice versa.

2, overall timing function:

When using overall timing function, its process is similar to above-mentioned split timing function, elder generation's clockwise direction rotates inner button 911 and outer knob 912 respectively and is indicated on the time indication panel 10 time value (as being set at 30 minutes) accordingly, promptly specifies overhead cam 7 travel times identical with following cam 8 travel times (promptly 30 minutes); Clockwise direction regulation stall switch 92 selected overall regularly gears (as being chosen to be 1 grade) rotate common gear speed regulator, the selected gear (as being chosen to be 2 grades) of working at the beginning at last then.At this moment, fan electromotor is started working (being that fan electromotor is started working from 1 grade), and just fan electromotor is connected working power by basic timing controlled circuit.When overhead cam 7, following cam 8 time value (using up in promptly 30 minutes) of having walked simultaneously and having set, stop member 3 falls into the breach 73 of overhead cam 7 and the breach 83 of following cam 8 simultaneously, conducting metal body 81 on conductive metal contact on the stop member 3 and the following cam 8 be electrically connected disconnection, the selected gear of common gear speed regulator quit work (promptly 2 grades quit work).Again because the breach 73 on the overhead cam 7 is slightly less than down the breach 83 on the cam 8, at this moment, conductive metal contact 72 electrical connection that contacts in the breach 73 of the conductive metal contact on the stop member 3 and overhead cam 7, fan electromotor is changed to overall timing gear work on (be fan electromotor be transformed into 1 grade automatically work on) automatically, because when using overall timing function, conductive metal contact 72 electric currents in the breach 73 of overhead cam 7 are switched on always, therefore, when stop member 3 falls into the breach 73 of overhead cam 7, fan electromotor is to work always, up to manual deenergization, just can quit work.Realize the fluid drive of fan motor therefrom, thereby realize controlling at times automatically the effect of air output size, to satisfy of the requirement of different periods of people different wind speed.As a same reason, also can realize from " working for 1 grade-2 grades, " always up to manually stopping; " work for 3 grades-1 grade, " up to manually stopping always; Air-supply process such as " always work for 3 grades-2 grades, up to manually stopping ", vice versa.

3, basic timing function:

When using basic timing function, similar to above-mentioned overall timing function, earlier clockwise direction rotation inner button 911 and outer knob 912 are indicated on the time indication panel 10 time value (as being set at 30 minutes) accordingly respectively, promptly specify overhead cam 7 travel times identical with following cam 8 travel times (promptly 30 minutes); Regulation stall switch 92 is selected (anticlockwise as shown in Figure 3 split is gear regularly) gear (as being chosen to be 3 ' grade) then, in basic timing function, driving switch 92 clockwise overall timing gears can not use, otherwise the timing function of being realized is overall timing function.Fan electromotor is started working (promptly starting working from 3 ' grade), covers setting-up time when cam rows up and down, and fan electromotor quits work.In basic timing function, the utility model is equivalent to one and has the timer that gear is regulated and timing function is combined as a whole.And when driving switch 92 is chosen to be 0 grade, be the timing function that the common mechanical timer of existing market is realized.

In the present embodiment, above-mentioned by clockwork spring, escape wheel 2, and the escapement formed of plurality of gears, the brake apparatus of forming by stop member 3 and back-moving spring and some present embodiments do not state trickle structure etc. and belong to common mechanical formula conventional structure that timer has in the art, so this detailed description not.In addition, also can be on architecture basics of the present utility model, set up the gear-like cam respectively in overhead cam 7, following cam 8 bottoms, and between the teeth groove of gear-like cam, be provided with conductive metal contact separately, and be provided with the stop member or the conductive contact blade that touch cooperation accordingly, can realize the air supply modes of realizing as existing electronic circuit board such as " natural wind " function simultaneously.
