Description

Technical Field

[0001] This utility model relates to the field of oral irrigators, and more particularly to a universal oral irrigator nozzle. Background Technology

[0002] A water flosser is an effective tool for improving oral health, especially suitable for people who want to deeply clean their teeth or have special oral needs. Choosing the right model and nozzle, and using it correctly, can maintain oral hygiene and prevent oral problems.

[0003] Chinese Patent CN215384800U discloses a nozzle mounting structure for a water flosser and a water flosser. The nozzle is inserted into a first through hole in the top cover of the water flosser, which communicates with a water outlet inside the water flosser. The nozzle inserted into the first through hole is detachably connected to a snap-fit ​​device provided on the water flosser. The snap-fit ​​device includes: a fastener comprising two elastically connected snap-fit ​​arms, at least one snap-fit ​​arm having a snap-fit ​​portion; the nozzle having a locking groove adapted to the snap-fit ​​portion; and a push button having at least one pushing portion inserted between the two snap-fit ​​arms, the two snap-fit ​​arms having at least one force-bearing portion adapted to the position of the pushing portion. Water flossers using the above nozzle mounting structure have the advantages of simple nozzle disassembly and assembly, and low manufacturing and assembly costs.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the nozzle sprays water in a single direction, making it difficult to thoroughly clean the oral cavity. Utility Model Content

[0005] The purpose of this invention is to address the problem of the single water spray direction of water flosser nozzles in the prior art, and to propose a universal water flosser nozzle.

[0006] The technical solution of this utility model: a universal dental irrigator nozzle, comprising:

[0007] The nozzle rod includes a vertical section and a water outlet section located at the top of the vertical section. The nozzle rod has a hollow structure.

[0008] And a universal water spray valve, which is set in the water outlet section at the top of the nozzle rod through a nozzle plug, forming a 360° circumferential water outlet.

[0009] Preferably, the universal water spray valve includes a base and a central column disposed on the base. A communication channel is provided on the central column and the base. The central column is made of flexible material and swings with its connection point with the base as the center point during water spraying.

[0010] Preferably, the nozzle plug is cylindrical, and the outer circumferential surface of the nozzle plug and the inner circumferential surface of the nozzle rod are provided with mutually mating threads. The bottom of the nozzle plug presses against the base, and the central column extends into the nozzle plug.

[0011] Preferably, the base is cylindrical with its opening facing the nozzle plug, and a ring is provided at one end of the nozzle plug, which is inserted into the cylindrical base.

[0012] Preferably, the inside of the nozzle plug is a conical surface, and the diameter of the cross-sectional circle of the conical surface gradually increases in the direction that it moves away from the nozzle rod.

[0013] Preferably, the central column is made of silicone, which, under the action of water flow, swings around the conical surface of the nozzle plug in a circular motion to form a 360° omnidirectional spray state.

[0014] Preferably, a limiting ring is provided on the inner wall of the water outlet section of the nozzle rod, and an annular groove that cooperates with the limiting ring is provided on the outer wall of the nozzle plug.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: the universal water spray valve is made of slender and thin-walled silicone. When a strong water flow passes through the nozzle rod and is sprayed out from the central channel of the silicone valve, the central column of the silicone valve is relatively soft. Under the action of the water flow, it swings around the conical surface of the nozzle plug in a circular motion, forming a 360° universal spray state, which achieves an all-round cleaning effect on teeth, replacing the traditional one-way nozzle and more effectively protecting teeth.

[0020] Example 1

[0021] like Figures 1-2 As shown, the universal dental irrigator nozzle proposed in this utility model includes:

[0022] The nozzle rod 1 includes a vertical section and a water outlet section disposed at the top of the vertical section. The vertical section and the water outlet section are integrated. In an optional embodiment, the vertical section and the water outlet section are arranged at a 90-degree angle. The nozzle rod 1 has a hollow structure for water supply.

[0023] And the universal water spray valve 3 is set in the water outlet section at the top of the nozzle rod 1 through the nozzle plug 2, and the universal water spray valve 3 forms a 360° circumferential water outlet.

[0024] Example 2

[0025] like Figure 3 As shown, this utility model proposes a universal dental irrigator nozzle, and compared with Embodiment 1, this embodiment provides a detailed description of its structure.

[0026] The universal water spray valve 3 includes a base 5 and a central column 4 set on the base 5. A channel 6 is provided on the central column 4 and the base 5 to supply water. The central column 4 is made of flexible material. During the water spraying process, the central column 4 swings irregularly with its connection point with the base 5 as the center point.

[0027] Furthermore, the nozzle plug 2 is cylindrical, with mating threads on its outer circumference and the inner circumference of the nozzle rod 1. The bottom of the nozzle plug 2 presses against the base 5, and the central column 4 extends into the nozzle plug 2. The base 5 is a cylindrical shape with its opening facing the nozzle plug 2. A ring is provided at one end of the nozzle plug 2, and the ring is inserted into the cylindrical base 5, thus fixing the base 5. The inside of the nozzle plug 2 is a conical surface 8, and the diameter of the cross-section of the conical surface 8 gradually increases in the direction gradually moving away from the nozzle rod 1. The central column 4 is made of slender and thin-walled silicone. When a strong water flow passes through the nozzle rod 1 and is then ejected from the channel 6 on the central column 4, the central column 4 is relatively flexible and, under the action of the water flow, swings around the conical surface 8 of the nozzle plug 2 in a circular motion, forming a 360° omnidirectional spray state.

[0028] Furthermore, a limiting ring 7 is provided on the inner wall of the water outlet section of the nozzle rod 1, and an annular groove that cooperates with the limiting ring 7 is provided on the outer wall of the nozzle plug 2. The limiting ring 7 is inserted into the annular groove, which improves the stability of the nozzle plug 2.

[0029] In summary, when this utility model is in use, the universal water spray valve 3 is made of slender and thin-walled silicone. When a strong water flow passes through the nozzle rod 1 and is sprayed out from the central channel 6 of the silicone valve, the central column 4 of the silicone valve is relatively soft. Under the action of the water flow, it swings around the conical surface 8 of the nozzle plug 2 in a circular motion, forming a 360° universal spray state, which achieves an all-round cleaning effect for teeth, replacing the traditional one-way nozzle and more effectively protecting teeth.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
