| 摘要 |
<p>The invention relates to a device (1) for ejecting droplets of an electrically non- conductive medium at a temperature of 360°C or above. The device (1) comprises a fluid chamber body (3), the fluid chamber body having a fluid chamber for containing an electrically non-conductive medium at a temperature of 360°C or above and for containing a conductive medium. The fluid chamber comprises an orifice (4). In the fluid chamber, at least a part of the electrically non-conductive medium is positioned closer to the orifice (4) than the conductive medium. The device (1) further comprises heating means (12, 15, 16) for heating the electrically non-conductive medium and actuation means, the actuation means comprising electrodes (10) for generating a current in the conductive medium and magnets (8) for generating a magnetic field in the conductive medium.</p> |
