AI Technical Summary
When cleaning dried or high-viscosity ink condensates, the kinetic energy of the airflow in existing inkjet printer printhead devices is insufficient to completely remove the condensates, resulting in unsatisfactory cleaning results.
The design employs a periodic rotating working disc and heating element inside the working cylinder, along with wedge blocks and wedge grooves. Through heating preheating and negative pressure back suction, it softens and peels off uncured ink, preventing the formation of condensates.
It effectively reduces the initial adhesion strength of condensate, ensuring that the printhead does not develop stubborn adhesion during long periods of standby or intermittent printing, thus keeping the printhead clean.
