Patent attributes
An ink jet head structure and an adhering method thereof are provided. The ink jet head structure has ink accommodated therein, and the ink is jetted with the operation of the actuator. The ink jet head structure includes a first substrate, a second substrate, and a third substrate sandwiched between the first and the second substrates. A first fluid passage is formed between the first and the third substrates, and a second fluid passage is formed between the second and the third substrates. By injecting glue between the first and the second fluid passages, the first, second and third substrates are bonded. When the actuator operates, the reservoir disposed in the three substrates may jet the ink accommodated therein from the ink outlet thereof, thereby achieving the purpose of easy bonding and ink jetting.
