[0002] In the cardboard box production process, invisible inkjet printers are used to print anti-counterfeiting labels or traceability information on the surface of the boxes. The ink stains on the surface of the printhead need to be cleaned regularly to ensure the clarity of the printing. Traditional inkjet printer printhead cleaning methods mostly rely on manual operation. However, when cleaning the printhead manually, high-pressure water jets or sprays can easily splash, causing cleaning fluid to drip onto the workbench, polluting the work environment. Furthermore, water stains can seep into the equipment, causing short circuits or corrosion.

[0003] Therefore, how to achieve closed-loop cleaning of the inkjet printhead and avoid overflow and pollution of cleaning water has become a technical problem that urgently needs to be solved in this field. Utility Model Content
