Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail:
See Fig. 1, Fig. 2, the embodiment of a kind of air blowing type adsorption electrode of this utility model harvester, comprise: conducting wire 12-1, electrode slice 5, bowl-shape sucker 1, one electrode conductor 3 is set in bowl-shape sucker 1, conducting wire 12-1 is connected with electrode conductor 3, electrode slice 5 is fixed on the end face of electrode conductor 3, electrode conductor bottom 4 is provided with an exhaust manifolds jack 2.The sidewall that 1 liang, bowl-shape sucker is relative has air inlet 10 and air vent 9, and the two ends of exhaust manifolds jack 2 are docked with air inlet 10 and air vent 9 respectively.An air inlet pipe 11 is had to be arranged on the air inlet 10 of bowl-shape sucker 1, the other end of air inlet pipe 11 is connected with a vacuum pump 14, there are exhaust manifolds 7 to be successively connected with air inlet pipe 11 through air vent 9, exhaust manifolds jack 2, have an exhaustor 8 to be connected with exhaust manifolds 7 through air vent 9.Air inlet pipe 11 footpath is greater than the internal diameter of exhaust manifolds 7, and exhaustor 8 has an air entry 15 with the junction of exhaust manifolds 7, and air entry 15 is arranged in the gap of bowl-shape sucker 1 and electrode conductor 3.
Specifically, the outer surface of above-mentioned air inlet pipe 11 is conductive material, one end that air inlet pipe 11 stretches in bowl-shape sucker 1 is connected with the air inlet 10 on electrode conductor 3, lead one end of pipe 12 of the other end and that air inlet pipe 11 stretches out bowl-shape sucker 1 is connected, the pipe 12 that leads has included described conducting wire 12-1 and venting channels, conducting wire 12-1 one end is drawn and is connected with electrocardiograph 13 from the pipe 12 that leads, and the other end of the pipe 12 that leads is connected to the gas outlet of vacuum pump 14.
Electrode conductor 3 end face is identical with electrode slice 5 shape size, has screw, be fixed on the end face of electrode conductor 3 by electrode slice 5 with nylon screw 6 in the middle of electrode slice 5 and electrode conductor 3 end face.The bottom of electrode conductor 3 is cylinders, and bowl-shape sucker 1 has columniform cavity, and the cylinder external diameter of electrode conductor 3 bottom is less than the cavity inside diameter of bowl-shape sucker 1.
Bowl-shape sucker 1 arranges a screw be communicated with air vent 9 near air vent 9 place, air inlet pipe is fixed on the air vent 9 of bowl-shape sucker 1 with a hold-down screw.
Above-mentioned electrode slice 5 is silver/silver chloride foundry goods electrode, and have strong anti-interference performance, certainty of measurement is high, and noise is little, the fireballing advantage of efferent echo.
