s103, controlling the opening and closing states of the glaze spraying holes so as to enable the glaze in the conveying channel to be sprayed out of the glaze spraying holes.
In step S102, the pressure of the pressurized gas is stabilized, and in addition, the glaze is pressurized and conveyed by inputting the glaze into the first container and then by the pressure of the air pressure, so that the influence of pressure fluctuation generated when the conveying device (such as a pump) directly supplies the glaze to the glaze distributor on the glaze spraying effect can be avoided. Step S103 is a printing process. According to the glaze spraying control method, the glaze is firstly input into the first container and then is pressurized and conveyed through the pressure of air pressure, so that the influence of pressure fluctuation generated when a conveying device (such as a pump) directly supplies the glaze to the glaze distributor on the glaze spraying effect can be avoided. Finally, the glaze spraying valve is controlled to open or close the glaze spraying hole so as to control the glaze in the conveying channel to be sprayed out from the glaze spraying hole, thereby realizing numerical control glaze spraying printing.

Through steps S107 and S108, the liquid is caused to flow reciprocally in the first container and the second container; when the liquid is glaze, the purpose of preventing solid matters in the glaze from depositing is achieved; when the liquid is a cleaning liquid, step S107 and step S108 are rinsing processes in the cleaning process to form a flushing, rinsing effect by reciprocally transferring the cleaning liquid in the first container and the second container. The cleaning liquid may be water or a mixed solution of water and a cleaning agent, for example.
By performing step S107 and step S108, the cleaning liquid can be reciprocally transferred between the first and second vessels 200 and 300, thereby flushing the frit remaining on the first and second vessels 200 and 300 and the glaze spraying module 400, and achieving high cleaning.
