[0002] Industrial nozzles are key components used in industrial production to atomize, spray, and mist fluids such as liquids and gases. Their core function is to change the shape or direction of the fluid through a specific structure to meet process requirements.

[0003] Traditional nozzles are mostly one-piece structures, or the nozzle head is fixedly connected to the connecting base and cannot be separated. When it is necessary to change to a different spray type, such as from a fan shape to a cone shape or when the nozzle head is worn, the entire nozzle must be removed from the pipeline. It is impossible to replace the nozzle head component separately, which results in the undamaged connecting structure being discarded, causing material waste and significantly increasing maintenance costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] Please see Figure 1 - Figure 5 This utility model discloses a modular industrial nozzle that is easy to install and disassemble, including a connecting base 1 with a fluid channel inside, and also including a nozzle assembly 4 and a fixing assembly 6, wherein: The inner wall of the connecting base 1 is provided with connecting threads 2 for fixing with external pipes, and the outer wall of the end of the connecting base 1 away from the pipe is provided with an L-shaped snap-fit ​​groove 3. The nozzle assembly 4 includes a nozzle 41, and a snap ring 42 is fixedly connected to the rear end of the nozzle 41. The inner wall of the snap ring 42 is provided with a snap block 43 that slides with the L-shaped snap groove 3. The fixing component 6 includes a fixing sleeve 61 and a return spring 62 sleeved on the outside of the connecting base 1. The two ends of the return spring 62 are fixedly connected to the inner wall of the fixing sleeve 61 and the outer wall of the connecting base 1, respectively. The fixing sleeve 61 abuts against the side of the snap ring 42 facing each other to lock the nozzle assembly 4 and the connecting base 1.

[0017] The number of L-shaped snap-fit ​​grooves 3 and snap-fit ​​blocks 43 are four in each case and correspond one-to-one. The four L-shaped snap-fit ​​grooves 3 are evenly distributed along the outer circumference of the connecting base 1, and the thickness of the snap-fit ​​block 43 is adapted to the groove width and gap of the L-shaped snap-fit ​​groove 3.

[0018] The nozzle assembly 4 and the connecting base 1 are fitted with a sealing ring 45, which is embedded in the end face of the snap ring 42 facing the connecting base 1.

[0019] The nozzle 41 and the snap ring 42 are integrally formed, and the spray outlet of the nozzle 41 can be set as a fan shape or a cone shape to adapt to different industrial spraying process requirements.

[0020] In this embodiment, the connecting base 1 is fixed to the external pipe by the connecting thread 2. After one installation, there is no need to disassemble it repeatedly. The snap-fit ​​block 43 of the nozzle assembly 4 is aligned with the axial section of the L-shaped snap-fit ​​groove 3 of the connecting base 1 and inserted. After rotating a certain angle, the snap-fit ​​block 43 enters the circumferential locking section of the L-shaped snap-fit ​​groove 3 to achieve initial positioning. The sealing ring 45 is compressed when the nozzle assembly 4 and the connecting base 1 are in contact to form a sealing structure to prevent high-pressure fluid leakage. The return spring 62 provides a continuous elastic preload. Through the abutment of the fixing sleeve 61 and the snap-fit ​​ring 42, the nozzle assembly 4 can be pressed tightly onto the connecting base 1 to ensure the reliability of the locking. Example 2

[0021] Based on the above embodiment 1, please refer to the appendix.

The sliding strip 5 and the sliding groove 63 are axially slidingly engaged. The end face of the fixed sleeve 61 near the snap ring 42 is provided with several limiting blocks 64. The end face of the snap ring 42 near the fixed sleeve 61 is provided with limiting grooves 44 corresponding to the limiting blocks 64. The reset spring 62 drives the fixed sleeve 61 to move the limiting blocks 64 into the limiting grooves 44.

[0022] The outer wall of the fixing sleeve 61 is provided with anti-slip texture 65, which is annular raised ridges evenly distributed along the circumference of the fixing sleeve 61.

[0023] In this embodiment, the sliding engagement between the sliding strip 5 and the sliding groove 63 guides the fixed sleeve 61 to move smoothly along the axial direction, so that the elastic force of the return spring 62 is evenly transmitted, ensuring smooth locking and unlocking actions, and ensuring that the limiting block 64 on the fixed sleeve 61 can be accurately inserted into the limiting groove 44 of the snap ring 42 for limiting. The limiting block 64 and the limiting groove 44 fit together to restrict circumferential rotation, and the presence of the anti-slip texture 65 makes it easy for the operator to manually press and slide the fixed sleeve 61.

[0024] Working principle and usage process of this utility model: The connecting base 1 is fixed to the external pipe by the connecting thread 2, and does not need to be disassembled repeatedly after one installation; When installing the nozzle assembly 4, first press the nozzle assembly 4 downwards, and the return spring 62 is in a compressed state. Then, align the snap block 43 of the nozzle assembly 4 with the axial section of the L-shaped snap groove 3 of the connecting base 1 and insert it. After rotating a certain angle, the snap block 43 enters the circumferential locking section of the L-shaped snap groove 3 to achieve initial positioning. The sealing ring 45 is compressed when the nozzle assembly 4 and the connecting base 1 are in contact, forming a sealing structure. After the nozzle assembly 4 is initially positioned, the nozzle assembly 4 is released, the return spring 62 releases its elastic force, and drives the fixing sleeve 61 to move axially along the fixing sleeve 61 and abut against the snap ring 42, so that the limiting block 64 on the fixing sleeve 61 can be accurately inserted into the limiting groove 44 of the snap ring 42 for limiting, thus pressing the nozzle assembly 4 onto the connecting base 1 and completing the installation work. In subsequent use, nozzle assemblies 4 with different spray nozzle types can be replaced according to different processes.
