The liquid level tube of bottle is rushed, there is gap, the upper end of liquid level tube and entering for circulating pump between the lower end of liquid level tube and the bottom of surge flask
Mouth is connected, and the outlet of circulating pump is connected with assistant print cartridges.
Preferably, first pressure sensor, first pressure sensor electrical connection are equipped between the liquid level tube and circulating pump
Controller, controller are electrically connected circulating pump.
Preferably, second pressure sensor, the electrical connection of second pressure sensor are equipped between the ink outlet port and surge flask
Controller.
Preferably, the single-chip microcontroller of the model C8051F0500 of the controller.
Preferably, the bottom of the assistant print cartridges is connected with ink inlet opening.
The utility model has the following beneficial effects:
1, a kind of spray head ink circulation system provided by the utility model, is made by surge flask, circulating pump and assistant print cartridges
Ink is constantly recycled along circulation line, is effectively prevent ink deposition, is kept spray head constant temperature.For more in compared with the existing technology
A ink outlet port needs to be arranged multiple circulation loops with multiple ink inlet openings and compares, and the spray head ink circulation system of the utility model only needs
Want a circulating pump that ink circulation can be realized.
2, the spray head ink circulation system is passed by the first pressure sensor and second pressure being arranged on circulation line
Ink pressure in sensor real-time monitoring circulation line, and by the adjusting of controller progress circulating pump, make in circulation line
Ink keeps stablizing flow velocity.
