Zero level is exported with the original state of output end Q2, control end T1 and control end T2 meets the Vout_2 of high level, T triggerings
The input end of clock CK1 of device T_1 is high level, and its output end Q1 upsets are output high level, the clock of a T triggers T_1
Input CK1 is low level, and its output end Q2 keeps output zero level, and the output end of the 3rd delay circuit is also low level, i.e.,
The PIN6 of the driving chip of motor 6 is high level, and PIN7 is low level, so that motor 6 drives paddle to rotate forward；When the first time delay
After circuit reaches predetermined delay time, its output high level, then the output end output high level of the first OR gate OR_1, makes output end
Q1 upsets are output zero level, and the PIN6 of the driving chip of motor 6 is zero level, while the input of the second delay circuit and second
The first input end of OR gate OR_2 is high level, and due to the time-lag action of the second delay circuit, the second of the second OR gate OR_2 is defeated
Enter end also in low level, the second OR gate OR_2 output high level overturns output end Q2 and is output high level, prolongs due to the 3rd
When circuit time-lag action, the PIN7 of the driving chip of motor 6 is also zero level, and the both end voltage of motor 6 is zero, and motor 6 is not braking,
Because Resistance motor 6 of the paddle in water is stalled rapidly；After motor 6 is stalled, the 3rd delay circuit reaches predetermined delay time,
Its output end exports high level, makes the PIN7 of the driving chip of motor 6 for high level, and now PIN6 is zero level, so that motor 6
Drive paddle reversion；After second delay circuit reaches predetermined delay time, its output end output high level turns over output end Q2
Switch to export zero level, then through the 3rd delay circuit time delay after, make the PIN7 of the driving chip of motor 6 for zero level, now PIN6
It is zero level, stalls motor 6.So as to reach the automatic control motor of cleaning control circuit 16 after reset switch S1 is clicked
6 drive stirring sheets 601 first rotate forward the purpose for a period of time inverting stopping after a period of time again, and then cause in fore filter 1
The rotation of water body both forward and reverse directions rinse stainless steel filtering net 5, increase the relative velocity of water body and stainless steel filtering net 5, make stainless
Steel filter screen 5 obtains fully washing away for multi-angle, the impurity on stainless steel filtering net 5 is washed within the shorter time, and enters
The water intake velocity of water pipe 9 is varied without, and the cleaning speed of fore filter 1 is accelerated so as to reach and cleaning water consumption is reduced
Purpose.
Simultaneously the 3rd delay circuit cause motor 6 rotate forward stop a period of time after invert again, it is to avoid motor 6 is because cutting rapidly
Change positive and negative then damage motor 6, extend the service life of motor 6.
Motor 6 is opened simultaneously, and motor 6 drives paddle to rotate, and then stirs the water in fore filter 1 by paddle
Body, rotates the water body in fore filter 1, and then increases the relative velocity of water body and stainless steel filtering net 5, makes stainless steel filtering net
5 are more fully washed away, and the impurity on stainless steel filtering net 5 is washed within the shorter time, the water inlet of water inlet pipe 9
Speed is varied without, and the cleaning speed of fore filter 1 is accelerated so as to reach and the purpose of cleaning water consumption is reduced.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should be pointed out that right
For those skilled in the art, some improvements and modifications under the premise of the utility model principle is not departed from,
These improvements and modifications also should be regarded as protection domain of the present utility model.
