Answer electric grade.
Above-mentioned innovative point role:
1, the utility model nozzle mounting seat and stage type tapered electrode ring two parts are needed to carry out electrostatic by screw connection
When spray operations, it is only necessary to be directly mounted at such electrostatic attraction electrode on original common spray head, depend merely on electrode with traditional electrode
It is more firm that damping between mounting hole and nozzle carrys out stationary phase ratio.Under traditional electrode and the connection type of nozzle, induced electricity
Pole can only use 3-5 times, will lead to electrode and nozzle junction loosens, can not be used again.Improved electrode installation side
Just, it can disassemble, reuse, the service life is longer repeatedly.
2, the copper foil that traditional electrode scalloped inner surface attaches is excessively thin, easily punctures and aoxidizes under 10,000 volts of electrostatic potential
Broken, service life is extremely limited, needs to frequently replace copper foil, and workload is very big, is not easy volume production.And more importantly passing
The copper-foil conducting electricity of system electrode attaches in scalloped inner surface, and electrification copper foil in this way has very big probability directly to spray with from spray head
The contact of droplet beam, eventually lead to droplet and get to copper foil surface, on the one hand generate electric leakage and causes electric quantity loss, influence electrode to mist
Drip the induction charging efficiency of beam.Another aspect fine mist is adsorbed on sector electrode inner surface by the effect of electrostatic field, is gathered into
Stream, influences Spray Uniformity.
The utility model avoids electrodes conduct copper sheet and droplet beam because conductive copper plate is mounted on 7 outer surface of separation layer
It directly contacts, and then solves directly contact and bring drawbacks described above.And since conductive copper plate embedded groove is arranged in electrode interior, just
It is 4 times of copper foil in traditional electrode on thickness, charging performance is stronger, and service life is more in installing the copper sheet thicker than copper foil
It is long, do not have to frequently replacement.
3, different from traditional electrode size, the utility model electrode size is bigger, and increases in shell outer and attach one layer
Copper foil, as the second level outer layer induction electrode of electrode, its effect is not for the charging of droplet beam but uniform droplet beam, because
To be found by the test of traditional induction electrode, when droplet beam passes through traditional induction electrode, in droplet flow field droplet due to
Electrode plate distance is different, and stress size is also different, causes the uniformity otherness of different location droplet in droplet flow field very big.Mirror
Increase outer copper foil induction electrode 6 in such case, a polarity is applied to the droplet beam charged again and is charged with droplet
The identical electric field force of property, plays the purpose of uniform-mist drip field uniformity.
