[0014] As shown in Figures 1 to 3 , a spray needle comprises a ceramic spray needle body, which is composed of a rear end fixing part 1, an intermediate flow guide part 2, and a front end flow guide needle tip 3. The intermediate flow guide part 2 is provided with an integrally formed annular tooth block 4. The annular tooth block 4 is uniformly provided with teeth, and the teeth form water flow channels between them. The front end flow guide needle tip 3 is sleeved with a cluster net 5 and a cluster ring 6. The front end of the cluster net 5 is conical and abuts against the rear end of the cluster ring 6. The rear end of the cluster ring 6 is provided with an inward taper. The cluster net 5 is composed of a front end taper ring and a rear end column ring. The rear end column ring and the front end taper ring are both provided with straight tooth blocks 7. Adjacent straight tooth blocks 7 also form water flow channels, so that water flow can pass through the annular tooth block 4 and the cluster net 5 and finally be sprayed out after entering the cluster ring 6. The intermediate flow guide part 2 and the front end flow guide needle tip 3 are integrally formed and conical with a smaller front end and a larger rear end.

[0015] As shown in Figure 1 , Figure 4 , a nozzle using the above spray needle comprises a nozzle body 8 and a connecting seat body 9. The rear end fixing part of the spray needle is provided with a locking part 10. The intermediate flow guide part 2 and the front end flow guide needle tip 3 are inserted into the nozzle body 8 and connected with the nozzle body 8 by the locking part 10. Generally, a threaded connection mode is adopted for locking. The lower part of the nozzle body 8 is provided with a water inlet connector 11, which is connected with the connecting seat body 9. For different situations, a lengthening pipe 12 can be additionally arranged at the water outlet of the nozzle body. The length of the lengthening pipe 12 can be selected and adjusted. Generally, a threaded connection mode is adopted for fixing.
