Using the technical solution of the present embodiment, electrode assembly 30 can be charged with valve block ontology 20 and mutually insulated, makes electricity
Pole component 30 forms capacitance structure with valve block ontology 20.According to the definition of capacitance：
The distance between capacitance C and two electrode plates d, the dielectric of opposite medium between area coverage S and electrode plate are normal
Number ε is related, and one of which changes, then capacitance C accordingly changes.Electrode assembly 30 is respectively equivalent to an electricity with valve block ontology 20
Pole plate, when electrode assembly 30 is charged with valve block ontology 20, the first end of valve block ontology 20 is fixedly connected with valve block baffle 10,
The second end of valve block ontology 20 under external force can be close to valve block baffle 10, and above-mentioned distance d changes, and then capacitance C
