Description

Technical Field

[0001] This utility model relates to the field of oral hygiene technology, specifically to a water flosser nozzle. Background Technology

[0002] Oral irrigators, as commonly used oral hygiene aids, use high-pressure water jets to impact the tooth surface, interdental spaces, and gingival sulcus to remove food debris and plaque, thus helping to maintain oral health. The nozzle, as the core component of the oral irrigator, directly affects cleaning effectiveness, user comfort, and applicable scenarios due to its structural design.

[0003] Current oral irrigator nozzles are mostly cylindrical or conical in shape, and the water outlets are mostly circular or oval. These designs are poorly adapted to irregular gaps such as between teeth, making it difficult for the high-pressure water flow to fully cover the inner walls of these gaps, easily creating cleaning blind spots. This is especially problematic for the dark triangle areas formed by receding gums, where cleaning is ineffective. Furthermore, current oral irrigator nozzles only have a single water outlet at the front, resulting in a unidirectional water flow that only impacts a specific area within the gap. This fails to achieve multi-directional, all-around cleaning, making it difficult to thoroughly remove stubborn plaque and food debris from these areas. Utility Model Content

[0004] This invention provides a water flosser nozzle that enables multi-directional and all-round cleaning of the interdental spaces, especially the black triangular areas formed after gum recession.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A water flosser nozzle includes a connecting seat and a nozzle body. The connecting seat and the nozzle body have a through flow channel along the axial direction. The rear end of the connecting seat is a water inlet, and the front end of the nozzle body is a water outlet. The water inlet and the water outlet are connected through the flow channel. The water outlet is triangular. The nozzle body is a triangular prism with its cross-sectional dimensions gradually decreasing from the rear end to the front end. Several side water outlet holes are evenly distributed on the three side faces of the nozzle body, and the side water outlet holes are connected to the flow channel.

[0006] Furthermore, all three side facets are concave inward to form an arc-shaped curved surface.

[0007] Furthermore, the side water outlet is inclined towards the front end, and the axis of the side water outlet forms an acute angle with the axis of the guide channel.

[0008] Furthermore, both the front and rear ends of the nozzle body are triangular.

[0009] Furthermore, the nozzle body has a triangular front end and a circular rear end.

[0010] Furthermore, the nozzle body has a circular front end and a triangular rear end.

[0011] Furthermore, the edges of the nozzle body are rounded.

[0012] Furthermore, the nozzle body is made of food-grade silicone or medical-grade plastic.

[0013] Furthermore, the rear end of the connector is connected to a spray bar, which is detachably connected to the main unit of the oral irrigator.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The nozzle is a triangular prism with a tapered front end, which makes it easy to align and match the black triangular gaps between teeth. The water outlet is triangular, and the sprayed water jet matches the shape of the black triangular area between teeth, achieving effective cleaning.

[0015] 2. The side face of the triangular prism nozzle is a concave arc-shaped surface, which makes the side water outlet of each surface form a layout that "inclins towards the inner wall of the interdental space". Combined with the acute angle design between the side water outlet and the arc-shaped surface, the water jet is more concentrated and accurately aimed at the side wall of the interdental space. The water flow can cover the three side walls of the interdental space from different directions, expand the cleaning coverage, and achieve multi-directional and all-round cleaning.

[0016] 3. The multi-outlet structure enables multi-directional cleaning with "front-facing direct spray + side-facing oblique spray", which can fully cover the inner wall of the interdental spaces, thoroughly remove food debris and plaque, and greatly improve cleaning efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figure 1 As shown, a water flosser nozzle includes a connecting seat 7 and a nozzle body 1. The connecting seat 7 and the nozzle body 1 have a through flow channel 4 arranged along the axial direction inside. The nozzle body 1 has a water inlet 2 at the rear end and a water outlet 3 at the front end. The water inlet 2 and the water outlet 3 are connected by the flow channel 4 arranged along the axial direction inside the nozzle body 1. The water outlet 3 is triangular.

[0023] The nozzle body 1 is a triangular prism, and its cross-sectional dimensions gradually decrease from the rear end to the front end. The specific shape can be implemented in the following ways: The first implementation method, such as Figure 2 As shown, the front and rear ends of the nozzle body 1 are both triangular.

[0024] The second implementation method, such as Figure 3 As shown, the nozzle body 1 has a triangular front end and a circular rear end.

[0025] The third implementation method, such as Figure 4 As shown, the nozzle body 1 has a circular front end and a triangular rear end.

[0026] The connecting seat 7 is cylindrical or triangular prism-shaped. The edges of the nozzle body 1 are rounded.

[0027] A plurality of side water outlet holes 6 are evenly distributed on the three side facets 5 of the nozzle body 1, and the side water outlet holes 6 are connected to the guide channel 4. The three side facets 5 are all concave inward to form arc-shaped curved surfaces, and the side water outlet holes 6 are inclined towards the front end, with the axis of the side water outlet hole 6 forming an acute angle with the axis of the guide channel 4. Preferably, the acute angle is 30°-60°.

[0028] The nozzle body 1 is made of food-grade silicone or medical-grade plastic.

[0029] The rear end of the connecting seat 7 is connected to the spray bar, which is detachably connected to the main unit of the oral irrigator.

[0030] When using, aim the nozzle at the gap between your teeth (black triangle). The water jet from the nozzle matches the shape of the black triangle area between your teeth. Combined with the water jet from the side outlet, it can effectively clean the gaps between your teeth and the surrounding tooth surface and gums, achieving multi-directional and all-round cleaning.

[0031] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
