An ink jet device includes a print head, an ink tank containing ink therein, a first motor, a second motor, and a control unit. The ink tank is connected with the print head and configured for supplying ink to the print head. The ink contained in the ink tank exerting a static hydraulic pressure onto the print head. The first motor is configured for driving the print head to move in a direction selected from the group consisting of a vertical direction, a horizontal direction, and a combination thereof. The second motor is configured for substantially simultaneously driving the ink tank to move in response to vertical movement of the print head so as to maintain the static hydraulic pressure that the ink exerts on the print head.

An exemplary clamping apparatus includes a supporting body, a plurality of clamping units installed on the supporting body, a PWM controller, and a detection unit. Each clamping unit includes a magnet, a clamping pin, an electrical coil, and a coil core mechanically engaged with the clamping pin. The magnet is configured for holding the clamping pin at a target position. The PWM controller is configured for supplying a pulse signal to the respective electrical coil of each clamping unit and for thereby creating a magnetic force causing a corresponding coil core and a corresponding clamping pin to, synchronously, move. The detection unit is configured for detecting a back electromotive force representative of the arrival to the target position of a clamping pin and signaling the PWM controller to stop supplying the pulse signal. A clamping process utilizing the clamping apparatus is also provided.

A print head includes a nozzle plate, a fixing plate fixed to the nozzle plate, an oscillation sheet, and a security assembly. The fixing plate defines a receiving groove. The oscillation sheet is fixed between the fixing plate and the nozzle plate and covers the receiving groove. The security assembly includes a fixing component, an elastic component, a fixing element, an anti-detachable component, and a pointed tip extending from a distal end of the anti-detachable component. The security assembly is fixed to the fixing plate, the elastic component and the anti-detachable component are received in the receiving groove with the pointed tip pointed towards the oscillation sheet. A first end of the compressed elastic component resists against the fixing component and a second end of the elastic component resists the anti-detachable component.
