Embodiment Construction
[0047] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0048] The present invention provides a nozzle device, including a nozzle 10 and a dredging mechanism 11. The dredging mechanism 11 includes a dredging pipe 110 that communicates with the nozzle 10 and can feed a medium with pressure to the nozzle 10 to dredge the blocked nozzle 10 and is sleeved on the The outside of the dredging pipe 110 is used to seal the sealing member of the dredging pipe 110 , and the sealing member is provided with a drain opening 126 for discharging the pressurized medium after the dredging is blocked. By setting the dredging pipe 110 communicated with the nozzle 10, the medium with pressure can be passed into the nozzle 10 so as to dredg...
