LIQUID PUMP HAVING A PIEZOELECTRIC MEMBER AND INKJET APPARATUS HAVING THE SAME |
| 摘要 |
A liquid pump includes a piezoelectric pump unit and a control unit. The piezoelectric pump unit includes an inlet, an outlet, and a chamber formed between the inlet and the outlet, and a wall of the chamber includes a piezoelectric member. The control unit is configured to apply to the piezoelectric member, a first voltage in a polarization direction of the piezoelectric member and a second voltage in a direction opposite to the polarization direction, such that the piezoelectric member is deformed. The first voltage is greater than the second voltage. |
