Description

Technical Field

[0001] This utility model relates to the field of portable oral irrigators, and in particular to an oral irrigator nozzle assembly. Background Technology

[0002] Existing oral irrigators typically feature multiple nozzles, and these nozzles are usually integrated into a single unit. The nozzle is mounted on the main unit of the oral irrigator via a snap-fit ​​connection. For example, patent CN214679058U discloses an oral irrigator nozzle mounting structure and an oral irrigator that employs this integrated nozzle structure.

[0003] However, since a single oral irrigator unit requires multiple integrated nozzles, the manufacturing cost of these nozzles is high. Furthermore, during use, the nozzle needs to be replaced when irrigating different areas of the mouth; however, after prolonged use, excessive insertion and removal can cause the nozzle connections to loosen, ultimately affecting the stability of the nozzle connection. Summary of the Invention

[0004] The purpose of this invention is to provide an oral irrigator nozzle assembly that can effectively solve the problems existing in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An oral irrigator nozzle assembly includes a nozzle head, a curved section, and a straight section;

[0007] The nozzle has an internal water outlet channel; one end of the nozzle has a water outlet that communicates with the water outlet channel.

[0008] The bent section has a first connector and a second connector arranged at an angle; the first connector is detachably connected to the end of the nozzle facing away from the spray nozzle, so that the water outlet channel communicates with the inside of the bent section; the second connector is detachably connected to one end of the straight section, so that the bent section communicates with the inside of the straight section.

[0009] The straight pipe section is provided with a clamp and a water inlet at the end opposite to the curved pipe section.

[0010] Furthermore, a positioning plane is provided on the outer side of the straight pipe section, and the positioning plane is parallel to the central axis of the straight pipe section.

[0011] Furthermore, the outer side of the first connector is provided with a first external thread; the end of the water outlet channel opposite to the water nozzle is provided with a first internal thread that is screwed into the first external thread.

[0012] Furthermore, the outer side of the end of the nozzle facing away from the water spray nozzle is provided with an uneven first anti-slip texture.

[0013] Furthermore, a third connector is provided at the end of the straight tube that is away from the clamp connector, and a second external thread is provided on the outer side of the third connector; a second internal thread is provided on the inner side of the second connector that is screwed into the second external thread.

[0014] Furthermore, the outer surface of the second connector is provided with an uneven second anti-slip texture.

[0015] Furthermore, a gripping portion is provided at one end of the straight tube near the third connector.

[0016] Furthermore, the included angle between the first connector and the second connector is 90° or 120°.

[0017] The beneficial effects of this utility model are as follows: The oral irrigator nozzle assembly of this utility model allows for easy replacement of only the curved section when rinsing different areas of the mouth, eliminating the need to replace the nozzle head and straight section, thus significantly reducing the manufacturing cost of the nozzle assembly. Furthermore, since frequent insertion and removal of the straight section is eliminated, the problem of loosening at the nozzle connection due to excessive insertion and removal is effectively solved, improving the stability of the nozzle assembly connection.

[0018] Figure 1 This is a schematic diagram of the structure of an oral irrigator nozzle assembly provided by this utility model.

[0019] Figure 2 This is a schematic diagram of another embodiment of the bend section.

[0020] Figure 3 This is a schematic diagram of the cross-sectional structure at point AA of the straight pipe section. Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3As shown, an oral irrigator nozzle assembly includes a nozzle head 1, a curved section 2, and a straight section 3. The nozzle head 1 has an internal water outlet channel; one end of the nozzle head 1 has a spray nozzle communicating with the water outlet channel. The curved section 2 has a first connector 21 and a second connector 22 arranged at an angle; the first connector 21 is detachably connected to the end of the nozzle head 1 opposite to the spray nozzle, so that the water outlet channel communicates with the interior of the curved section 2; the second connector 22 is detachably connected to one end of the straight section 3, so that the curved section 2 communicates with the interior of the straight section 3; the end of the straight section 3 opposite to the curved section 2 is provided with a snap-fit ​​connector 31 and a water inlet.

[0023] Specifically, in this embodiment, the snap-fit ​​connector 31 is used to engage with the snap-fit ​​structure on the oral irrigator main unit. For example... Figure 3 As shown, a positioning plane 33 is provided on the outer side of the straight tube section 3, and this positioning plane 33 is parallel to the central axis of the straight tube section 3. During installation, the positioning plane 33 makes positioning contact with the outer shell of the vision module, which can improve the structural stability of the nozzle assembly.

[0024] Furthermore, a third connector 32 is provided at one end of the straight pipe section 3 away from the snap-fit ​​connector 31. The outer side of the third connector 32 is provided with a second external thread 321; the inner side of the second connector 22 is provided with a second internal thread that is screwed into the second external thread 321. In use, the connection between the bent pipe section 2 and the straight pipe section 3 is achieved by screwing the second external thread 321 into the second internal thread.

[0025] In this embodiment, a gripping part 34 is provided at one end of the straight tube section 3 near the third connector 32 to facilitate fixing the straight tube section 3 during disassembly and assembly.

[0026] In this embodiment, the outer side of the first connector 21 is provided with a first external thread 211; the end of the water outlet channel opposite to the water nozzle is provided with a first internal thread that is screwed into the first external thread 211. In use, the connection between the inside of the bend 2 and the water outlet channel of the nozzle 1 is achieved by screwing the first external thread 211 and the first internal thread.

[0027] In this embodiment, preferably, the included angle between the first connector 21 and the second connector 22 is 90° or 120°, such as... Figure 1 and 2 As shown.

[0028] Furthermore, the outer surface of the end of the nozzle 1 facing away from the spray nozzle is provided with an uneven first anti-slip texture 11. The outer surface of the second connector 22 is provided with an uneven second anti-slip texture 221. In this embodiment, by providing the first anti-slip texture 11 and the second anti-slip texture 221, the nozzle 1 and the bend 2 can be easily screwed on and off to achieve quick assembly and disassembly.

[0029] This embodiment of an oral irrigator nozzle assembly allows for the following installation methods: The nozzle assembly is secured to the oral irrigator main unit via a snap-fit ​​connector 31 on the bent tube 2; the bent tube 2 is detachably connected to the straight tube 3 via a second connector 22; and the nozzle head 1 is detachably connected to the bent tube 2 via a first connector 21. Alternatively, the nozzle head 1, bent tube 2, and straight tube 3 can be assembled as a single unit before snapping the connector 31 of the bent tube 2 onto the oral irrigator main unit. When different areas of the oral cavity need irrigating, only different bent tubes 2 need to be replaced, significantly reducing the manufacturing cost of the nozzle assembly. Furthermore, since frequent insertion and removal of the straight tube 3 is unnecessary, the problem of loosening at the nozzle connection due to excessive insertion and removal is effectively solved, improving the stability of the nozzle assembly connection.

[0030] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
