[0027] Specifically, the upper side of nozzle body 2 is provided with limiting ring 12, the size of limiting ring 12 is adapted to the inner diameter of connecting sleeve 1.

[0028] Please refer to Figures 1 to 2 Limiting ring 12 is inserted in the inside of connecting sleeve 1 by fitting the inner diameter of connecting sleeve 1, can effectively limit the position of nozzle body 2, prevent the nozzle assembly from swinging in the process of using.

[0029] Specifically, the inner wall of nozzle body 2 is provided with cleaning plate 13, the upper surface of cleaning plate 13 is provided with pollution discharge thorn 14, the position of pollution discharge thorn 14 is adapted to the position of filter hole in filter screen 4, the inside of cleaning plate 13 is provided with drainage hole, and the drainage holes are evenly distributed in the inside of cleaning plate 13.

[0030] Please refer to Figure 3 to Figure 6 , by the setting of the cleaning plate 13 and the pollution spike 14, the filter screen 4 is blocked, the water pressure increases, the filter screen 4 is extruded, slides down along the connecting slide rod 3, moves towards the cleaning plate 13, and the pollution spike 14 is inserted into the filter hole of the filter screen 4. The impurities blocked at the filter screen 4 are knocked off, so that the self-cleaning of the filter screen 4 is realized, and at the same time, under the action of the drainage hole of the cleaning plate 13, the normal flow of the cleaning liquid is facilitated.

[0031] Specifically, the number of the shunt hole 6 is several, which are uniformly distributed in the inside of the nozzle body 2, and the side of the filter screen 4 coincides with the shunt hole 6 under the condition that the first spring 5 is not stressed.

[0032] Please refer to Figure 2 to Figure 3 , the setting of multiple shunt holes 6 can quickly shunt and discharge the cleaning liquid and cleaning impurities in the nozzle body 2 at multiple positions when the filter screen 4 is blocked, so that the nozzle assembly can quickly restore normal operation.

[0033] Specifically, the outer surface of the connecting sleeve 1 is provided with a connecting lug 15, and the number of the connecting lug 15 is several, which are uniformly distributed on the outer surface of the connecting sleeve 1.

[0034] Please refer to Figure 7, the setting of multiple connecting lugs 15 can effectively complete the stability of the connection of the nozzle assembly while realizing the connection of the nozzle assembly with the external cleaning liquid connecting pipe.

[0035] Specifically, the nozzle body 2 is inserted into the inside of the connecting sleeve 1, and the limiting ring 12 and the rubber sealing gasket 9 abut each other.

[0036] Please refer to Figure 1 , after the nozzle assembly is installed to the corresponding position, the limiting ring 12 is extruded, and then the rubber sealing gasket 9 and the supporting ring 8 are extruded, so that the supporting ring 8 slides down, the second spring 11 is stretched, and under the elastic force of the second spring 11, the rubber sealing ring is always tightly limited to the limiting ring 12, which ensures the sealing performance of the connection of the nozzle assembly.

After the connection is completed, when the nozzle assembly is used, the external cleaning liquid enters the inside of the nozzle body 2, and after being filtered by the filter screen 4, the cleaning liquid is discharged from the outlet of the nozzle body 2 through the discharge hole of the cleaning plate 13. After being used for a period of time, the impurities in the cleaning liquid block the filter screen 4, and as the cleaning liquid connecting conduit continues to output, the pressure at the filter screen 4 gradually increases, until the filter screen 4 slides along the connecting slide plate, the first spring 5 is stretched, and the pollution pick 14 is inserted into the filter hole of the filter screen 4, so that the impurities blocked at the filter screen 4 are knocked off, so that the self-cleaning of the filter screen 4 is realized. At the same time, the filter screen 4 slides down and leaks out of the shunt hole 6, so that the cleaning liquid in the nozzle body 2 and the impurities cleaned out are discharged from the shunt hole 6, and the self-treatment of the impurities is completed. With the discharge and shunting of the impurities, the water pressure at the filter screen 4 gradually balances, and under the elastic force of the first spring 5, the filter screen 4 is reset to block the shunt hole 6 again, so that the nozzle assembly can continue to work normally, and the nozzle assembly of the screen printing and engraving machine has the effects of preventing impurities from blocking the nozzle and self-cleaning the impurities, and the nozzle assembly of the screen printing and engraving machine has the effect of improving the sealing performance of the nozzle.
