[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 The present invention provides a detachable micro-nozzle connection structure, which includes: an installation tube 1 and a micro-nozzle 2.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 A top ring 11 is fixedly installed at the top of the mounting tube 1, and a connecting tube 12 is fixedly installed on the top ring 11. A connecting tube 21 is fixedly installed at the bottom of the micro nozzle 2, and the outer wall of the connecting tube 21 abuts against the outer wall of the connecting tube 12. A mounting cylinder 3 is fixedly installed on the outside of the connecting tube 12 at the top of the top ring 11. A slot 31 is opened inside the mounting cylinder 3, and a mounting groove 32 is opened inside the slot 31. A limiting block 221 is provided inside the mounting groove 32. A connecting rod 22 is fixedly installed on the top of the limiting block 221. The top of the connecting rod 22 is fixedly connected to the outer wall of the connecting tube 21, and the limiting block 221 and the mounting groove 32 are attracted to each other by a magnetic block.

[0026] It should be noted that by installing the micro nozzle 2 using a magnetic insertion method, it is possible to quickly disassemble it without the need for additional tools during subsequent use. Furthermore, the magnetic insertion method has a simple overall structure, relatively low production costs and precision requirements, making it easier to promote and use.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 The slot 31 is fitted with a sliding limit rod 4. The outer wall of the limit rod 4 abuts against the outer wall of the limit block 221. The bottom end of the limit rod 4 is attracted to the top ring 11 by a magnetic block. The top end of the limit rod 4 is located outside the mounting cylinder 3 and is fitted with a fixed connecting rope 41. The end of the connecting rope 41 away from the limit rod 4 is fixedly connected to the top ring 11.

[0028] It should be noted that: the misalignment between the limit block 221 and the slot 31 can be achieved by rotating the limit block 221 after it is inserted. Then, by inserting the limit rod 4 inside the slot 31, the trajectory of the limit block 221 falling off during use can be blocked, thereby improving the connection stability of the micro nozzle 2 during later use and reducing the phenomenon of the micro nozzle 2 falling off due to its large internal size during use.

[0029] In this embodiment, by setting the connecting rope 41, after the limiting rod 4 is pulled out from the slot 31, the connecting rope 41 can hold the limiting rod 4, thereby preventing the limiting rod 4 from falling off and being lost at will.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4 The connector 12 has a groove 121 inside, and the interior of the connector 12 has a stepped structure. The outer wall of the insertion tube 21 also has a stepped structure. Each stepped layer of the outer wall of the insertion tube 21 is equipped with a fixedly connected sealing rubber ring 211. Multiple sealing rubber rings 211 abut against the top of the connector 12, the inner wall of the groove 121, and the top of the top ring 11, respectively. A fixedly connected magnetic ring 122 is installed on the top of the connector 12, and the top of the magnetic ring 122 abuts against and attracts each other to the outer wall of the insertion tube 21.

[0031] It should be noted that by setting the inner wall of the connecting tube 12 and the outer side of the insertion tube 21 as a stepped structure, when the insertion tube 21 is inserted into the connecting tube 12 during installation, the sealing rubber ring 211 at the bottom of each step can be deformed due to compression, thereby making the insertion connection between the insertion tube 21 and the connecting tube 12 more effective and reducing the phenomenon of leakage at the connection during use.

[0032] In this embodiment, the multiple limiting top rings 11 can be connected by connecting rings to form a whole with the multiple limiting rods 4, so that when in use, the operator can release the limiting of all the limiting blocks 221 at once.

[0033] The working principle of the detachable micro-nozzle connection structure provided by this utility model is as follows:

[0034] When using this device, the installation tube 1 in the device can be fixedly connected to the required pipe first. Then, the micro nozzle 2 can be taken out. By inserting the limiting block 221 into the slot 31, when the limiting block 221 moves to the bottom of the slot 31, the micro nozzle 2 can be controlled to rotate and move into the installation groove 32. At this time, the limiting block 221 can be attracted to the inner wall of the installation groove 32 by the magnetic block on the outer wall.

[0035] Then, the limiting rod 4 can be removed and inserted into the slot 31. At this time, the bottom end of the limiting rod 4 can be attracted to the top of the top ring 11 through the magnetic block, thereby achieving stable positioning of the slot 31 and completing the connection of the micro nozzle 2. In subsequent use, when the micro nozzle 2 is subjected to the impact of internal water pressure, the vertical trajectory of the micro nozzle 2 can be limited by the abutment between the limiting block 221 and the mounting slot 32. The insertion and installation of the limiting rod 4 can also limit the horizontal sliding trajectory of the limiting block 221, thereby improving the stability of the micro nozzle 2 during use.

[0036] Since the micro nozzle 2 is fixed by magnetic insertion, when it is necessary to disassemble the micro nozzle 2 during subsequent use, simply pull out the limit rod 4 upwards, control the micro nozzle 2 to rotate, and lift it up and down to quickly disassemble the micro nozzle 2.

[0037] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
