Fig. 1 is the structural representation of the soil level pick-up unit of lampblack absorber according to an embodiment of the invention, and wherein, lampblack absorber comprises metal screen 10 and metal guide oil groove 20.
As shown in Figure 1, the soil level pick-up unit of this lampblack absorber comprises: capacitive detection module 30 and control module 40, wherein, the first input end of capacitive detection module 30 is connected with metal screen 10, second input end of capacitive detection module 30 is connected with metal guide oil groove 20, capacitive detection module 30 is for detecting the capacitance between metal screen 10 and metal guide oil groove 20, control module 40 is connected with the output terminal of capacitive detection module 30, and control module 40 judges the soil level of lampblack absorber according to capacitance.
Usually, all there is in lampblack absorber metal screen 10 and metal guide oil groove 20, and as can be seen from the setting position of metal screen 10 and metal guide oil groove 20, a plane-parallel capacitor can be formed between metal screen 10 and metal guide oil groove 20, and in an embodiment of the present invention, make use of the soil level of plane-parallel capacitor to lampblack absorber that existing metal screen 10 and metal guide oil groove 20 in lampblack absorber form just and detect.
