[0002] An irrigator is an auxiliary tool for cleaning the oral cavity. It uses pulsed water flow to clean teeth and the gaps between teeth. It mainly includes portable and desktop types. An irrigator is a structure used for oral care. It uses a certain pressure to spray a column of cleaning water from the nozzle of the irrigator to clean the user's mouth. The bottom inlet position of the nozzle of the irrigator is usually movably connected to a nozzle barrel, which makes it easy to disassemble the nozzle. The water flows from the inside of the nozzle barrel into the nozzle and then sprays out from the head of the nozzle.

[0003] However, the connection position between the nozzle and the nozzle barrel is achieved by plugging or snapping, which makes it quickly detachable. However, during the plugging or snapping process, there are situations such as poor positioning and misalignment, which makes it inconvenient to quickly disassemble and assemble.

[0004] In view of the above problems, the present utility model is proposed. Utility Model Content

The area between the two first guide slides 18 at the lower end of the nozzle rod 1 is adapted to the second guide slide 21. The area between the two second guide slides 21 on the inner upper surface of the nozzle barrel 2 is adapted to the first guide slide 18. The spacing between the cover plate 11 and the first guide slide 18 is adapted to the thickness of the second guide slide 21. That is, the first guide slide 18 and the second guide slide 21 are staggered vertically, and the lower end of the nozzle rod 1 can enter the interior of the upper end of the nozzle barrel 2.

[0033] The upper surface of the cover plate 11 is further symmetrically provided with a guide mark 13, a locking pointed mark 14, an opening arrow mark 15, a locking state mark 16 and an opening state mark 17. The locking pointed mark 14 and the opening arrow mark 15 are located on both sides of the guide mark 13, and the opening state mark 17 and the locking state mark 16 are located on both sides of the guide mark 13. The locking arrow mark 14 and the opening arrow mark 15 serve as a guide to facilitate the rotation of the cover plate 11 and the nozzle rod 1;

[0034] The locking pointed mark 14 faces the locking state mark 16 , and the opening arrow mark 15 faces the opening state mark 17 .

[0035] The surface of the nozzle barrel 2 is also evenly and evenly provided with a plurality of protective patterns 22 distributed in a circular shape. The surface of the nozzle barrel 2 is also symmetrically provided with two groups of guide points 23, each group of guide points 23 having two. The protective patterns 22 can enhance friction.

[0036] The middle position of the two groups of guide points 23 is on the symmetry axis of the second guide slider 21. When the first guide slider 18 and the second guide slider 21 are connected together, the sharp part of the guide mark 13 is just facing the middle position of the two guide points 23.

[0037] The end of the guide mark 13 away from the center point of the cover plate 11 is sharp. A plurality of reinforcing ribs 12 are provided between the upper surface of the cover plate 11 and the surface of the nozzle rod 1 . The reinforcing ribs 12 can enhance the structural strength of the cover plate 11 and the nozzle rod 1 .

[0040] To summarize: Align the guide mark 13 with the quarter point of the nozzle barrel 2, which is the position where the surface of the nozzle barrel 2 is located in the middle of the guide points 23 on both sides. At this time, the first guide slider 18 and the second guide slider 21 are staggered up and down, and the lower end of the nozzle rod 1 can just be inserted into the upper open position of the nozzle barrel 2.

[0041] During insertion, the cover plate 11 fits snugly against the upper surface of the nozzle barrel 2. Then, the cover plate 11 and the nozzle rod 1 are rotated in the direction of the lock arrow mark 14. During the rotation, the first guide slider 18 fits snugly against the lower surface of the second guide slider 21. The lower surface of the cover plate 11 fits snugly against the upper surface of the second guide slider 21, i.e., the second guide slider 21 is located between the cover plate 11 and the first guide slider 18. The cover plate 11 is rotated until the second guide slider 21 touches the stop block 19.

[0042] At this time, the second guide slider 21 is fixed between the first guide slider 18 and the cover plate 11, and the cover plate 11 and the nozzle barrel 2 are connected as a whole. The sharp part of the guide mark 13 is just facing the guide point 23;

[0043] When the nozzle rod 1 needs to be removed, the cover plate 11 is installed and opened and rotated in the direction of the arrow mark 15 until the first guide slider 18 and the second guide slider 21 are staggered up and down. At this time, the nozzle rod 1 can be removed; the disassembly and assembly operation between the nozzle rod 1 and the nozzle barrel 2 is convenient, and the positioning is relatively direct and accurate.
