Abstract

The invention discloses a printer nozzle voltage control circuit and a printer. The printer nozzle voltage control circuit comprises a control sub circuit, a digital-to-analogue conversion sub circuit, a chip selection sub circuit and a monitoring sub circuit. The digital-to-analogue conversion sub circuit converts a digital driving signal output by the control sub circuit into an analog driving signal required by a printer nozzle, the digital-to-analogue conversion sub circuit is electrically connected with the chip selection sub circuit, and the chip selection sub circuit is electrically connected with the monitoring sub circuit. The digital-to-analogue conversion sub circuit converts a digital driving signal output by the control sub circuit into an analogue driving signal required by the printer nozzle; and the chip selection sub circuit is electrically connected with the monitoring sub circuit. The printer nozzle voltage control circuit and the printer provided by the invention have the advantages that the printing effect is improved, and the printer nozzle is protected against damage.

Description

[0001] This application is a divisional application of an invention patent application submitted on October 31, 2018, with the invention name "Printer Nozzle Voltage Control Circuit and Printer" and application number 201811288831.8. technical field [0002] The invention relates to the technical field of printing, in particular to a printer nozzle voltage control circuit and a printer. Background technique [0003] In the field of printing technology, when the piezoelectric printer is working, the print head is filled with ink and has a certain negative pressure. When the piezoelectric unit gives the print head a certain positive signal, the piezoelectric unit deforms to make the ink squeeze out from the nozzle, forming ink droplets and spraying on the printed item. However, if the force of the piezoelectric unit is not properly controlled, not only will the amount of ink ejected be inaccurate and the printing effect will be affected, but the nozzle of the printer will also...
