In order to which the technical solution of the utility model is more clearly understood, below to the utility model to the entire mistake of machine oil
Filtration journey illustrates.
For the filter core protective device of automobile engine oil strainer provided by the utility model, first, referring to Fig. 1
Shown in the directions arrow A, machine oil from the second filter plate 62 the second filter hole 621 enter, then pass through the first filter plate 61
On the first filter hole 611, then enter in filter core 100 from the oil inlet window 60 of the lower section of the first filter hole 611 again；
Then, machine oil flows out after the filtering of filtration core 100 among central tube 3, then again from center 4, along
The directions arrow B enter in the machine oil oil feed line outside the utility model.
As stepper motor 10 is powered by the extension of utility model works time at interval of predetermined period, stepping is controlled
Motor 10 carries out, and stepper motor 10 drives intermeshing gear ring 6 to rotate together by the gear 11 on its output shaft, then
So that the first filter plate 61 to link together with gear ring 6 moves therewith together, therefore, the first filter plate 61 after rotation, by
It is fixedly connected with the inner wall of shell 1 in the second filter plate 62 and holding position is constant, so as to make on the first filter plate 61
The second filter hole 621 in one filter hole 611 and the second filter plate 62 generates relative dislocation, therefore, it is possible to turn the first filtering down
Oil-through hole gap between hole and the second filter hole filters therefore, it is possible to the large granular impurity by machine oil in the generation that works long hours
Except the second filter plate 62, therefore, it is possible to significantly improve the work period of filter core, ensures the filter efficiency of filter core, extend filter
The whole service life of core.
In summary technical solution is it is found that the structure of the first filter plate provided by the utility model and the second filter plate is set
It sets, may be implemented preferentially to filter the impurity of bulky grain except filter core, external impurity is effectively avoided to enter oil filtration
In the filter core of device, to improve the work period of filter core, and as the working time of oil filter extends, can suitably it adjust
The oil-through hole gap of small first filter hole and the second filter hole after relative dislocation, further enhances the filtering energy to foreign matter
Power.
