Description

Technical Field

[0001] This utility model relates to a dental flosser and its nozzle. Background Technology

[0002] Modern people are paying more and more attention to oral hygiene and have taken various measures to maintain oral health, including the use of water flossers. Water flossers work by using high-pressure water to rinse the mouth, cleaning teeth, gaps between teeth, and gums, effectively removing plaque, bacteria, and food debris, and preventing oral problems such as bad breath, tooth decay, and periodontitis. At the same time, it can also stimulate blood circulation in the gums, promoting oral health.

[0003] However, you must be careful when choosing a water flosser. Many water flossers on the market only have one nozzle, which means the water surface is limited and you feel a noticeable stinging sensation when rinsing your teeth at a single point, resulting in a poor user experience.

[0004] The above are the shortcomings of existing technologies. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a nozzle that allows the water to flow in a rotating manner, thereby improving the user experience and rinsing effect.

[0006] The technical solution of this utility model is: a water flosser nozzle, including a nozzle body, the nozzle body having a flow channel for water to pass through, the nozzle body having a nozzle, the nozzle including a cylindrical section, a conical section and a through hole section arranged from the inside out, the inner wall of the cylindrical section having an internal thread for connecting to the nozzle body, the inner wall of the conical section having a spiral water groove, the through hole being located at the bottom of the cone, and the outlet position of the flow channel being offset from the through hole position.

[0007] There are multiple flow channels.

[0008] The end of the flow channel forms a converging shape.

[0009] The nozzle body is provided with grooves and sealing rings.

[0010] The through hole is a round hole.

[0011] The nozzle is also provided with a recess, and the through hole is located in the recess.

[0012] Another technical solution of this utility model is: a water flosser, including the water flosser nozzle as described above.

[0013] The technical effects of this invention are as follows: First, water from the flow channel of the nozzle body flows into the water groove on the conical inner wall of the nozzle, rotating with the spiral water groove. One or more streams of water form a rotating water column that flows out from the through hole, providing a good rinsing effect and greatly improving the user experience. Second, the converging flow channel allows water to flow out at a faster speed and rinse in the spiral water groove, which can enhance the water rotation effect and obtain a better rinsing effect and user experience. Attached Figure Description

[0014] Figure 1 This is an external view of the nozzle of the water flosser of this utility model.

[0015] Figure 2 This is a cross-sectional view of the nozzle of the water flosser of this utility model. Detailed Implementation

[0016] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] See Figures 1-2 The nozzle of this utility model is mainly composed of a nozzle body 10. Two water channels 11 are provided inside the nozzle body 10, and a nozzle 20 is provided at the end of the nozzle body 10. The two water streams in the channels 11 merge into one in the nozzle 20 until they flow out of the nozzle 20.

[0018] To generate a rotating water column effect, the nozzle 20 of this invention features a unique design, comprising a cylindrical section 21 with internal threads, a conical section 22, and a cylindrical hole 23, arranged from the inside out. The internal threads are screwed into the external threads at the end of the nozzle body 10 to form a fixed connection. A spiral water groove is engraved on the inner wall of the conical section 22. The outlets of the two water channels face the spiral water grooves on the inner wall of the conical section 22. Under the influence of the spiral water grooves, the two streams of water from the two channels rotate and merge into one, flowing out from the through hole 23 at the bottom of the cone. Due to the inherent characteristics of the rotating water column, the rinsing effect is better, and the user experience is improved. It should be noted that the outlet position of the water channel being offset from the through hole position is a necessary condition for the water column to rotate.

[0019] At the end of the flow channel 11, a converging shape is formed, which allows the water to flow out at a faster speed and wash in the water tank of the conical section 22, which can improve the water rotation effect and obtain a better rinsing effect and experience.

[0020] The nozzle body 10 is provided with a groove and a sealing ring 101. After the nozzle is installed in place, the sealing ring 101 presses the nozzle tightly, which prevents the water flow with a certain pressure from flowing through the threaded joint of the internal and external threads.

[0021] The nozzle end face is provided with a recess 24. When the water flosser is turned off, due to the surface tension, the residual water adheres to the recess 24 and cannot come out, thus avoiding the trouble of wetting other places.

[0022] This embodiment has two flow channels, but the technical solution is not limited to this. Multiple flow channels can be set in the nozzle body and combined into one in the nozzle.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
