Description

Technical Field

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

[0002] There are many types of water flosser nozzles on the market, but many problems still exist in actual use. For example, the water flow channel design of some nozzles is not reasonable enough, which can cause water to flow turbulently in the channel, affecting the smoothness and stability of the water flow, thereby reducing the cleaning effect, and may even cause unnecessary irritation to the soft tissues of the mouth.

[0003] Therefore, how to develop a water flow channel design for a dental flosser nozzle is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] This utility model provides a water flosser nozzle and a water flosser, which aims to overcome the problems existing in the prior art.

[0005] This utility model provides a water flosser nozzle, comprising: The nozzle body has a nozzle head at one end and a connecting part at the other end. The nozzle body has a through water flow channel. The diameter of the water flow channel gradually decreases from the nozzle head to the connecting part and is set without steps. The roughness of the inner wall of the water flow channel is 0.16-0.25 μm.

[0006] In one implementation, the diameter of the flow cross-section near the nozzle of the water flow channel gradually decreases at an accelerated rate, forming an accelerated convergence section.

[0007] In one embodiment, one end of the nozzle body is bent away from the axis of the water flow channel.

[0008] In one embodiment, the bending angle of one end of the nozzle body is 45°-60°.

[0009] In one embodiment, a snap-fit ​​structure is provided on the outer side of the connecting part. The snap-fit ​​structure is an annular groove or protrusion, which is used to snap and fix it to the nozzle mounting seat of the water flosser.

[0010] In one embodiment, the connecting part is made of a plastic material.

[0011] In one embodiment, an umbrella-shaped flange is provided at one end of the nozzle body near the connecting part. The umbrella-shaped flange extends radially outward from the nozzle body from top to bottom, and its outer edge diameter is larger than the outer diameter of the connecting part and covers the connecting part.

[0012] In one embodiment, the outer side of the umbrella-shaped flange is provided with anti-slip texture, which is evenly distributed along the circumference of the umbrella-shaped flange.

[0013] In one embodiment, the nozzle body, water flow channel, connecting part, and umbrella-shaped flange are integrally formed.

[0014] This utility model also provides a water flosser, including a water flosser nozzle as described in any one of the above 9 items.

[0015] This embodiment of the invention optimizes the flow cross-section design of the water channel, setting the diameter of the flow cross-section from the nozzle to the connection part to gradually decrease and be stepless. This allows the water flow to gradually accelerate and remain stable during transmission, effectively avoiding water flow turbulence caused by steps or abrupt changes in cross-section, thereby improving cleaning efficiency and reducing irritation to the gums. Simultaneously, by controlling the inner wall roughness to 0.16-0.25μm, the frictional resistance between the water flow and the inner wall of the channel is further reduced, minimizing energy loss and allowing the water flow to transmit pressure more efficiently. This enhances cleaning power and also reduces irritation to oral soft tissues to some extent, improving user comfort. Attached Figure Description

[0023] Please see below. Figure 1 and Figure 2 The oral irrigator nozzle provided in this embodiment of the utility model specifically includes: The nozzle body 10 has a nozzle 11 at one end and a connecting part 12 at the other end. The nozzle body 10 has a through water flow channel 13 inside. The diameter of the water flow channel 13 gradually decreases from the nozzle 11 to the connecting part 12 and is set without steps. The roughness of the inner wall of the water flow channel 13 is 0.16-0.25 μm.

[0024] In this embodiment, by optimizing the flow cross-section design of the water flow channel 13, the diameter of the flow cross-section from the nozzle 11 to the connecting part 12 is set to gradually decrease and be stepless. This allows the water flow to gradually accelerate and remain stable during transmission, effectively avoiding water flow turbulence caused by steps or abrupt changes in cross-section, thereby improving cleaning efficiency and reducing irritation to the gums. Simultaneously, by controlling the inner wall roughness to 0.16-0.25μm, the frictional resistance between the water flow and the inner wall of the channel can be further reduced, reducing energy loss and allowing the water flow to transmit pressure more efficiently. This enhances cleaning ability and also reduces irritation to oral soft tissues to a certain extent, improving user comfort.

[0025] In one embodiment, the diameter of the flow cross-section of the water flow channel 13 decreases gradually at the end near the nozzle 11, forming an accelerating convergence section. This embodiment, through the design of the accelerating convergence section, allows the water flow to gain greater acceleration near the nozzle 11, further enhancing the impact force and concentration, thereby improving the rinsing effect on hard-to-clean areas such as between teeth and along the gum line; simultaneously, the structure maintains a stepless transition, ensuring flow stability and avoiding turbulence.

[0026] In one embodiment, one end of the nozzle 11 of the nozzle body 10 is bent away from the axis of the water flow channel 13.

[0027] Furthermore, the bending angle of one end of the nozzle body 10 is 45°-60°.

[0028] In this embodiment, by setting one end of the nozzle 11 as a bent structure, the water outlet direction of the nozzle 11 forms a suitable angle with the tooth surface, which facilitates the water flow to cut obliquely into the interdental spaces and gingival sulcus area, improving the accuracy and coverage of rinsing. Furthermore, by limiting the bending angle to between 45° and 60°, it is ensured that the water outlet direction can effectively act on the interdental spaces and gingival junction, while avoiding problems such as inconvenience in operation or dispersed rinsing force due to excessively large or small angles, thus achieving a good balance between cleaning effect and user comfort.

[0029] In one embodiment, a snap-fit ​​structure 14 is provided on the outer side of the connecting portion 12. The snap-fit ​​structure 14 is an annular groove or protrusion for snap-fitting and fixing with the nozzle mounting seat of the water flosser. Furthermore, the connecting portion 12 is made of a plastic material.

[0030] In this embodiment, by providing an annular groove or protrusion-shaped snap-fit ​​structure 14 on the outside of the connecting part 12, quick assembly and disassembly between the nozzle body 10 and the water flosser mounting seat can be achieved, improving ease of use. On this basis, by using a plastic material to prepare the connecting part 12, it is given good elastic deformation ability, ensuring that the structure is not easily damaged during the snap-fit ​​process and can maintain long-term connection stability.

[0031] In one embodiment, an umbrella-shaped flange 15 is provided at one end of the nozzle body 10 near the connecting portion 12. The umbrella-shaped flange 15 extends radially outward from the nozzle body 10 from top to bottom, and its outer edge diameter is larger than the outer diameter of the connecting portion 12 and covers the connecting portion 12.

[0032] In this embodiment, the umbrella-shaped flange 15 effectively prevents water from flowing back along the outer wall of the nozzle body 10 to the joint area between the connector 12 and the mounting base, avoiding the loosening of the snap-fit ​​structure 14 or the growth of bacteria due to water seepage, and improving the sealing and hygiene safety of the connector 12.

[0033] In one embodiment, the outer side of the umbrella-shaped flange 15 is provided with anti-slip texture, which is evenly distributed along the circumference of the umbrella-shaped flange 15. This embodiment enhances the friction when the user's fingers grip the umbrella-shaped flange 15 by providing circumferentially evenly distributed anti-slip texture on the outer side of the umbrella-shaped flange 15, making it easier to stably operate the nozzle for disassembly and assembly in humid environments, and further improving ease of use and user experience.

[0034] In one embodiment, the nozzle body 10 has a nozzle 11, a water flow channel 13, a connecting part 12, and an umbrella-shaped flange 15 as an integrally formed structure.

[0035] In this embodiment, the nozzle body 10 is manufactured by a one-piece molding process, which effectively avoids structural gaps caused by the assembly of multiple parts, improves the overall strength and sealing performance, and facilitates cleaning and maintenance, while reducing the risk of bacterial growth.

[0036] This utility model embodiment also provides a dental flosser, including a dental flosser nozzle as described in any one of the above 9 claims.
