[0002] UV nozzle is the core component of UV inkjet printer, responsible for accurately spraying UV ink in the form of tiny droplets onto the printing medium, widely used in advertising, packaging, building materials, electronics and other industries, for making high-quality advertising posters, product packaging, personalized custom products, etc. In the printing process, ink may be left in the nozzle or internal channel of the nozzle body, which can solidify if not cleaned for a long time, causing the nozzle body to be blocked. Regular cleaning can effectively remove these residues and impurities, keeping the nozzle body unobstructed.

[0003] However, the traditional UV nozzle cleaning method is highly dependent on manual operation, requiring the use of cleaning fluid, cotton swabs, cleaning cloth, syringes and other tools, which not only has a complicated process and is time-consuming and labor-intensive, but also requires high professional skills and experience of the operator. Once the operation is wrong, it is easy to cause physical damage to the nozzle or affect its spraying performance, and the traditional method is also difficult to effectively remove the residual water in the nozzle after cleaning. These residual water may cause corrosion problems of the nozzle, ultimately affecting the normal service life of the nozzle.

[0004] Therefore, there is an urgent need for a UV nozzle cleaning device with a circulating waterway to solve the above problems. INVENTION CONTENTS

At the same time, the fan 8 continuously operates to suck the external gas from the gas inlet 71 into the heating box 7. In the process of the gas entering the heating box 7, the gas will be double-filtered in sequence through the dust screen 72 and the filter core 73. The filtered gas is heated by the heating pipe 75, and then sent into the connecting pipe 4 by the fan 8, so that the heated gas is finally sprayed from the nozzle body 41 to dry, thereby removing the residual moisture in the nozzle body 41. After drying, the fan 8 and the heating module 74 are turned off, and the second valve 91 is rotated counterclockwise to close the gas conveying pipe 9.
