[0023] The support tube 18 is fixedly connected with the internal thread of the middle part of the protective cover 2, and the support tube 18 forms a supporting suspension effect with the liquid inside the main tank 13 through the protective cover 2. The transmission tube 3 is fixedly connected to the top of the support tube 18. The top of the support seat 19 is a recessed structure. The front and rear surfaces of the support seat 19 are both granular structures. The bottom of the support seat 19 is fixedly welded and connected to the outer surface of the outer end of the transmission tube 3 through one side of the top of the protective cover 2 to form a limited snap-fit ​​connection. The protective cover 2 is provided to provide protection measures for the tank equipment inside the shell 1. The first connecting ring 7 and the second connecting ring 10 are both connected to the front and rear sides of the support seat 19 through threaded adjustment on both sides of the outer end surface of the transmission tube 3. The first connecting ring 7 and the second connecting ring 10 are provided to improve the transmission efficiency. The stability between the delivery pipe 3 and the support seat 19, the snap-fit ​​support connection is formed between the top of the shell 1 and the protective cover 2, the shell 1 is welded and supported on the outside of the base 11, and the shell 1 and the base 11 are connected by welding to form a storage space, the solvent tank 12, the main tank 13 and the ink tank 14 are all in contact with the upper surface of the base 11. The solvent tank 12, the main tank 13 and the ink tank 14 are all in a limited snap-fit ​​connection with the inner side of the shell 1. When the ink concentration in the main tank 13 increases, the solvent can be supplied to the main tank 13 to control the viscosity. The solvent tank 12 and the main tank 13 are connected to the first U-shaped tube 15 pipe fitting, and the solvent tank 12 forms a pressure balance effect with the liquid inside the main tank 13 through the first U-shaped tube 15. The main tank 13 and the oil tank 14 are connected to the first U-shaped tube 15. The ink tank 14 is connected to the second U-shaped tube 16, and the main tank 13 forms a pressure balance effect with the liquid inside the ink tank 14 through the second U-shaped tube 16.

The piezoelectric element 6 is usually made of piezoelectric material, and the transmission tube 3 is made of hard stainless steel. The transmission tube 3 is connected to the pump body 4, the pressure reducing valve 5 and the piezoelectric element 6 through a series of pipelines. Through the set pump body 4, compressed air is used as a power source to promote the flow of ink through changes in air pressure. Through the set pressure reducing valve 5, the higher pressure provided by the pump body 4 is adjusted to a lower pressure that the nozzle 17 can withstand. This is to prevent the nozzle 17 from being damaged due to excessive working pressure, and also to ensure To ensure that the ink can be sprayed out smoothly, the piezoelectric element 6 is set, and when voltage is applied to these materials, they will produce dimensional changes, thereby generating vibrations.

The ink particles have different lateral offset distances according to the different charges and fall onto the printing target object.

[0024] Working principle: The ink supplied to the print head by the pump body 4 is used, and the inkjet device controls the movement of the nozzle 17 through the piezoelectric element 6 to achieve precise printing. The ink tank 14 is kept level with the liquid in the main tank 13 by the second U-shaped tube 16 through pressure control, providing a stable ink supply to the nozzle 17 to ensure the quality of printing. The pressure reducing valve 5 drives the precise movement of the nozzle 17 to achieve high-quality printing. The compressed air used by the pump body 4 is used as a power source to promote the flow of ink through changes in air pressure, providing a stable printing pressure for the nozzle 17 to ensure the quality of printing, and providing a stable power supply and a suitable operating environment for the inkjet printer. The protective cover 2, support seat 19, first connecting ring 7 and second connecting ring 10 are arranged to keep the transmission tube 3 containing the nozzle 17 and one side of the top of the protective cover 2 in a fixed and stable state. The particle structure on the front and rear sides of the support seat 19 can improve the friction between the first connecting ring 7 and the second connecting ring 10 and the front and rear sides of the support seat 19, thereby avoiding loosening of the transmission tube 3 between the first connecting ring 7 and the second connecting ring 10 and the support seat 19, preventing the coding device from being easily affected by external vibrations during the printing process, resulting in unstable printing quality or even printing errors, thereby improving printing quality and production efficiency.
