The bubble-breaking cylinder consists of an inlet section, a bubble-breaking section, and an outlet section. The top and bottom of the bubble-breaking section are rotatably connected to the inlet section and the outlet section, respectively.

[0004] The aforementioned patents or existing anti-crystallization nozzles have the following problems:

[0005] Existing anti-crystallization nozzles require disassembly for subsequent maintenance, which is inconvenient and leads to difficulties in disassembly and assembly during maintenance. Utility Model Content

Detailed Implementation

[0023] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a quick-release structure for an anti-crystallization spray nozzle, including a pipe 1, a disassembly and assembly structure 2 on the pipe 1, and a nozzle 3 on the disassembly and assembly structure 2. The nozzle 3 is a specially designed nozzle used to prevent or reduce the problem of solution crystallization clogging the nozzle during spraying.

[0025] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a quick-release structure for an anti-crystallization spray nozzle. The disassembly structure 2 includes a fixing sleeve 21, which is connected to the pipe 1. A connecting groove 22 is provided in the fixing sleeve 21, and a retaining ring 23 is provided in the fixing sleeve 21. There are three retaining rings 23, but there can also be two. No further limitation is made.

[0026] In this utility model, a connecting cylinder 24 is provided on the nozzle 3. The connecting cylinder 24 is connected to the connecting groove 22 to realize the connection between the connecting cylinder 24 and the fixing sleeve 21. The connecting cylinder 24 has an integrally formed interface 25 and an integrally formed slot 26 on its surface. The slot 26 communicates with the interface 25. The number of slots 26 is the same as that of the retaining rings 23. The retaining rings 23 are connected to the slots 26 to realize the limiting and fixing after the connecting cylinder 24 is connected to the fixing sleeve 21.

[0027] In this utility model, a limiting port 27 is provided on the fixing sleeve 21, a limiting block 28 is provided in the connecting cylinder 24, a spring 29 is fixed in the connecting cylinder 24, and a telescopic rod 210 is fixed in the spring 29. The telescopic rod 210 is fixed in the connecting cylinder 24, and the telescopic end of the telescopic rod 210 is fixed to the limiting block 28. There are two springs 29, which are located at the upper and lower ends of the limiting block 28 respectively, to ensure the stability of the limiting block 28. Of course, there can also be three springs 29, which are located at the upper and lower ends and the middle of the limiting block 28 respectively. Each spring 29 has the same structure.

[0028] The connecting groove 22 is equipped with a sealing ring 211. The sealing ring 211 is elastic. After the retaining ring 23 moves into the retaining groove 26, the top of the connecting cylinder 24 will push the sealing ring 211. When the telescopic rod 210 is compressed, it will push the connecting cylinder 24, so that the retaining ring 23 is pressed against the retaining groove 26, which improves the firmness of the connection.

[0029] The fixed sleeve 21 is provided with a sealing pressure ring 212 at its lower end, and the connecting cylinder 24 is provided with a pressure ring 213 on its surface. After the connecting cylinder 24 is fixed in the fixed sleeve 21, the pressure ring 213 will press against the surface of the sealing pressure ring 212, so that the connecting cylinder 24 and the fixed sleeve 21 are connected to seal the connection part.

[0030] Specifically, the connecting cylinder 24 is inserted into the connecting groove 22. At this time, the retaining ring 23 will align with the mating interface 25, pushing the sealing ring 211. Rotating the connecting cylinder 24 will rotate the retaining ring 23 into the retaining groove 26, thereby fixing the connecting cylinder 24 in the fixing sleeve 21. When the retaining ring 23 rotates to the end of the retaining groove 26, the limiting block 28 will align with the limiting port 27. Under the action of the spring 29, the limiting block 28 will be locked in the limiting port 27 to achieve rotational limitation of the connecting cylinder 24. When disassembly and maintenance are required, press the limiting block 28 to push it into the connecting cylinder 24. Then rotate the connecting cylinder 24 to make the retaining ring 23 rotate out of the retaining groove 26 and rotate the retaining ring 23 into the mating interface 25. Then the connecting cylinder 24 can be slid down to separate it from the fixing sleeve 21 for quick disassembly. This achieves the beneficial effect of making subsequent disassembly, maintenance or installation more convenient.
