Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] This utility model discloses a nozzle assembly for a nasal irrigator, such as... Figure 1-11 As shown, it includes: mounting base 1, mounting cover 2, water outlet connector 3 and nozzle rod 4. Mounting base 1 is used to install on the nasal irrigator main unit. Mounting base 1 and mounting cover 2 are detachably connected. Water outlet connector 3 is fastened to mounting base 1 and located inside mounting cover 2.

[0035] In this embodiment, the mounting base 1, the water outlet connector 3, and the nozzle rod 4 are interconnected to form a water outlet channel. One end of the nozzle rod 4 passes through the mounting cover 2 and is engaged with the water outlet connector 3. The other end of the nozzle rod 4 is fitted with a nose wash head 5, which has a through hole 51 communicating with the water outlet channel. In this embodiment, the mounting base 1 and the mounting cover 2 are fixedly connected by screws, and the water outlet connector 3 is fixedly connected to the mounting base 1 by screws.

[0036] It should be noted that, since the mounting base 1, the water outlet connector 3 and the nozzle rod 4 are interconnected and form a water outlet channel, the water flows out from the water outlet channel and is sprayed out from the through hole 51 of the nasal irrigator 5 to realize the nasal irrigation function. This provides a nozzle assembly for a nasal irrigator, which shortens the length of the nasal irrigator 5 and extends its service life.

[0037] like Figure 1-4 As shown, the nasal tip 5 is made of soft rubber. In actual implementation, the nasal tip 5 is made of silicone.

[0038] like Figure 3-7 As shown, an atomizing core 6 is installed inside the nozzle rod 4. The atomizing core 6 is used to atomize the nasal wash solution. One end of the atomizing core 6 is attached to the inner wall of the nozzle rod 4. The nozzle rod 4 is provided with a spray hole 41. In the specific implementation process, the spray hole 41 communicates with the inner cavity of the nozzle rod 4. The spray hole 41 includes a first hole section 411 and a second hole section 412 that pass through in sequence. The first hole section 411 is a circular hole, and the second hole section 412 is a conical hole.

[0039] It should be noted that the nasal rinse solution is atomized by the atomizing core 6 and sprayed out from the spray nozzle 41. The nasal rinse spray is suitable for children.

[0040] like Figure 3 and Figure 8 As shown, the atomizing core 6 is provided with multiple water channels 61 and multiple spiral guide channels 62. The water channels 61 and spiral guide channels 62 correspond one-to-one and are interconnected. The water channels 61 are disposed through the side wall of the atomizing core 6, and the multiple spiral guide channels 62 are distributed at one end of the atomizing core 6 and are interconnected. In a specific implementation, the number of water channels 61 and spiral guide channels 62 is set to three. The three water channels 61 are equally spaced on the side wall of the atomizing core 6, and the three spiral guide channels 62 are centrally symmetrically distributed at one end of the atomizing core 6.

[0041] It should be noted that the water flows sequentially through the mounting base 1, the water outlet connector 3, and the nozzle rod 4. Since the atomizing core 6 is interference-fitted into the nozzle rod 4, the water flows to the water channel 61, flows through the spiral guide channel 62 and is collected, and forms a dispersed atomized water mist through the micro spray holes 41.

[0042] like Figure 3 , Figure 8 and Figure 10 As shown, one end face of the atomizing core 6 is convex 63, and the nozzle rod 4 has a concave surface 42 that fits into the convex surface 63. It should be noted that the fit between the concave surface 42 and the convex surface 63 ensures that the water flow can only proceed along the direction of the spiral guide groove 62, thus guaranteeing the normal formation of water mist.

[0043] like Figure 1-11 As shown, a first sealing ring 7 is fitted onto one end of the mounting base 1. In this embodiment, the first sealing ring 7 is O-shaped and made of silicone material. The first sealing ring 7 seals the mounting base 1 and the nasal irrigator main unit to prevent water leakage.

[0044] like Figure 3 As shown, a second sealing ring 8 is fitted onto the nozzle rod 4 and abuts against the water outlet connector 3. In this embodiment, the second sealing ring 8 is O-shaped and made of silicone material. The second sealing ring 8 seals the water outlet connector 3 and the nozzle rod 4, allowing water to flow along the water outlet channel and preventing water leakage.

[0045] In the specific implementation process, a third sealing ring 9 is fitted on the water outlet connector 3 to abut against the inner wall of the mounting base 1. The third sealing ring 9 is O-shaped and made of silicone material. The third sealing ring 9 seals the water outlet connector 3 and the mounting base 1, so that water flows along the water outlet channel and prevents water leakage.

[0046] like Figure 1-4As shown, the water outlet connector 3 is equipped with a hook 31, and the nozzle rod 4 is equipped with a locking platform 43 that matches the hook 31. In specific implementation, two hooks 31 are used. The nozzle rod 4 is securely installed on the water outlet connector 3 by the engagement of the hooks 31 and the locking platform 43. The locking platform 43 is equipped with a limiting protrusion 45. The nozzle rod 4, the locking platform 43, and the limiting protrusion 45 are integrally formed. There are two limiting protrusions 45, which are distributed on both sides of the hook 31. By setting the two limiting protrusions 45, the nozzle rod 4 can be limited and installed, preventing the nozzle rod 4 from rotating on the water outlet connector 3 and ensuring the normal spray of water.

[0047] like Figure 5 , Figure 6 and Figure 11 As shown, the nozzle rod 4 is provided with a positioning strip 44, and the nasal washing head 5 is provided with a positioning groove 52 that engages with the positioning strip 44. In specific implementation, the number of positioning strips 44 and positioning grooves 52 is set to three.

[0048] like Figure 3 As shown, the bottom of the mounting base 1 is provided with a rotating locking block 11 for rotating the nozzle assembly onto the nasal irrigator main unit. In this embodiment, the number of rotating locking blocks 11 is set to two. By setting the rotating locking blocks 11, the nozzle assembly can be rotated onto the nasal irrigator main unit, which can realize quick disassembly and assembly, and facilitate the replacement of nozzle assemblies with different functions.

[0049] Working principle: When the nozzle assembly without the atomizing core 6 is installed, the water flows in from the bottom of the mounting base 1, passes through the water outlet connector 3 and the nozzle rod 4 in sequence, and after passing through the water outlet channel, the water is sprayed out from the through hole 51 of the nasal rinse head 5, thereby realizing the function of rinsing the nasal cavity.

[0050] When the nozzle assembly with atomizing core 6 is installed, water enters from the bottom of the mounting base 1, passes through the water outlet connector 3 and the nozzle rod 4 in sequence, and is atomized into water mist by the atomizing effect of the atomizing core 6, and is sprayed out from the through hole 51 of the nasal rinse head 5, thereby realizing the function of rinsing the nasal cavity, which is suitable for children's nasal rinse.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
