Description

Technical Field

[0001] This utility model relates to the field of etching processing, specifically to an etching nozzle that can be quickly disassembled. Background Technology

[0002] Etching is a precision machining technology widely used in microelectronics, semiconductors, printed circuit boards, and other fields. Its basic principle is to remove unprotected portions of a material's surface through chemical reactions or physical methods, thereby forming the desired pattern or structure on the material. During the etching process, the nozzle is a key component; by changing different nozzles, parameters such as the spray angle and spray range can be adjusted to meet the needs of different etching processes.

[0003] While existing nozzles can adjust parameters such as spray angle and range, their threaded connection necessitates the use of wrenches or other tools for disassembly and replacement. This increases operational complexity and can easily damage the nozzle or related components, affecting its sealing performance and lifespan. Therefore, this invention proposes a quick-disassembly etched nozzle. Summary of the Invention

One end of the spherical connector is provided with a detachable nozzle.

[0007] Furthermore, the quick-release assembly includes a sliding sleeve, a return spring, and several fixing blocks. The fixing blocks are located at one end of the movable sleeve. The sliding sleeve is slidably mounted on the outside of the fixed sleeve via the return spring. The sliding sleeve is provided with a fixing groove that cooperates with the fixing blocks.

[0008] Furthermore, one end of the sliding sleeve is provided with an outwardly extending boss.

[0009] Furthermore, the leak-proof component includes a support sleeve, a compression spring, and a slidable plug. The support sleeve is fixedly installed inside the fixed sleeve and the movable sleeve, the plug is slidably installed on the axis of the support sleeve, and the compression spring is located between the support sleeve and the plug.

[0010] Furthermore, one end of the support sleeve is provided with a limiting shaft, and the plug core is provided with a stepped shaft that cooperates with the limiting shaft.

[0011] Furthermore, the support sleeve is surrounded by several guide plates.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figures 1-5The present invention relates to a quick-release etching nozzle, comprising a fixed sleeve 1 and a movable sleeve 2. The end of the fixed sleeve 1 furthest from the movable sleeve 2 has a threaded interface for connection to spraying equipment such as a spray pipe. A quick-release assembly 3 is provided between the fixed sleeve 1 and the movable sleeve 2. Both the fixed sleeve 1 and the movable sleeve 2 contain leak-proof components 4. One end of the movable sleeve 2 has a spherical groove 21, within which a rotatable spherical connector 22 is installed. One end of the spherical connector 22 has a detachable nozzle 23. The rotatable spherical connector 22 allows for flexible adjustment of the nozzle 23's angle to meet different spray angle requirements. The other end of the spherical connector 22 is threaded to the nozzle 23, allowing users to replace the nozzle 23 with different structures to achieve different spraying effects.

[0022] The ball joint 22 can be selected with or without an extension tube, depending on the actual needs. When it is necessary to reduce the distance between the nozzle 23 and the object to be sprayed, the ball joint 22 with an extension tube can be selected for more precise spraying of the area to be treated. The ball joint 22 without an extension tube is suitable for standard or preset spraying distances.

[0023] The quick-release assembly 3 includes a sliding sleeve 31, a return spring 32, and several fixing blocks 33. The fixing blocks 33 are located at one end of the movable sleeve 2. The sliding sleeve 31 is slidably mounted on the outside of the fixed sleeve 1 via the return spring 32. The sliding sleeve 31 has a fixing groove 34 that mates with the fixing blocks 33. One end of the sliding sleeve 31 has an outwardly extending boss 35. A clamp is also provided on the outside of the fixed sleeve 1 to limit the distance at one end of the sliding sleeve 31, thereby preventing the sliding sleeve 31 from detaching from the fixed sleeve 1 and affecting normal user operation.

[0024] In use, the fixed sleeve 1 is installed on the spray pipe or other spraying equipment via the threaded interface. Then, by pressing and rotating the boss 35 on the outer side of the sliding sleeve 31, the fixed block 33 engages with the fixing groove 34 on the sliding sleeve 31. The elastic force of the return spring 32 then securely engages the fixed block 33 with the fixing groove 34, thus completing the quick installation of the movable sleeve 2. For disassembly, simply press and rotate the boss 35 to separate the fixed block 33 from the fixing groove 34, allowing for easy removal of the movable sleeve 2 and achieving quick disassembly.

[0025] The leak-proof component 4 includes a support sleeve 41, a compression spring 42, and a slidable plug 43. The support sleeve 41 is fixedly installed inside the fixed sleeve 1 and the movable sleeve 2. The plug 43 is slidably installed on the axis of the support sleeve 41. The compression spring 42 is located between the support sleeve 41 and the plug 43. The support sleeve 41 is fixedly installed inside the fixed sleeve 1 and the movable sleeve 2 by clamps, thereby ensuring the stability of the support sleeve 41.

[0026] like Figure 3 , Figure 4 As shown, when the movable sleeve 2 is inserted into the fixed sleeve 1, the internal plugs 43 come into contact with each other. Simultaneously, the compression spring 42 pushes the plugs 43 to slide along the axis of the support sleeve 41, allowing the movable sleeve 2 and the fixed sleeve 1 to communicate, thus enabling normal liquid flow. When the movable sleeve 2 is pulled out, the compression spring 42 releases its elasticity, pushing the plugs 43 to fit against the inner wall, achieving a sealing effect, preventing liquid leakage, and ensuring the sealing performance of the etching nozzle when not in use.

[0027] The support sleeve 41 has a limiting shaft 411 at one end, and the plug core 43 has a stepped shaft 431 that cooperates with the limiting shaft 411. The cooperation between the limiting shaft 411 and the stepped shaft 431 restricts the movement distance of the plug core 43, thereby ensuring flow between the movable sleeve 2 and the fixed sleeve 1. This prevents one plug core 43 from moving excessively while the other plug core 43 adheres to the inner wall, thus preventing liquid flow after installation.

[0028] In addition, the support sleeve 41 is surrounded by several guide plates 412. The guide plates 412 cause the liquid passing through the support sleeve 41 to rotate and flow in the pipe, thereby improving the mixing uniformity of the liquid and generating a certain shear force to prevent particle deposition, which would affect the sealing effect of the plug core 43.

[0029] One end of the movable sleeve 2 is provided with a nut block 5, through which an angle limiting hole 51 is provided to mate with the spherical connector 22. The nut block 5 mates with the movable sleeve 2 to form a spherical groove 21, allowing the spherical connector 22 to rotate freely within the spherical groove 21. The angle limiting hole 51 further limits the rotation angle of the spherical connector 22, allowing users to more precisely control the spray angle of the nozzle 23 to meet the needs of different application scenarios. The size of the angle limiting hole 51 is smaller than the maximum diameter of the spherical connector 22, thus ensuring that the spherical connector 22 will not fall out of the angle limiting hole 51 during rotation, increasing the safety and stability of use.

[0030] The beneficial effects of this utility model are as follows: The quick-release assembly 3 located between the fixed sleeve 1 and the movable sleeve 2 allows for rapid disassembly and replacement of the movable sleeve 2, thereby improving nozzle replacement efficiency. Furthermore, the leak-proof assembly 4 within the fixed sleeve 1 and the movable sleeve 2 ensures good sealing of the nozzle during use, preventing media leakage. Simultaneously, the combination of the ball joint 22, the ball groove 21, and the nozzle 23 allows users to adjust or replace the nozzle 23 as needed, thus meeting the requirements for adjusting the spray angle and spray range.
