Description

Technical Field

[0001] The invention relates to a tooth flushing device and a nozzle thereof. Background Art

[0002] Modern people pay more and more attention to oral hygiene and take various measures to maintain oral health, including the use of water flossers. The function of water flossers is to flush the mouth with high-pressure water to clean teeth, gaps between teeth and gums, effectively remove dental plaque, bacteria and food residues, and prevent oral problems such as bad breath, caries and periodontitis; at the same time, it can also stimulate blood circulation in the gums and promote oral health.

[0003] However, you must be cautious when choosing an oral irrigator. Many oral irrigators on the market have only one water outlet on their nozzles, and the rinsing surface is single. When rinsing the teeth at a single point, you will feel a noticeable stinging sensation, and the experience is poor.

[0004] The above are the defects of the prior art. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a nozzle, and a water flosser equipped with the nozzle can discharge water in a rotating manner, thereby improving the experience and flushing effect.

[0006] The technical solution of the present invention is: a water flosser nozzle, including a nozzle body, a flow channel for water to pass through the nozzle body, a nozzle body, and a nozzle. The nozzle includes a cylindrical section, a conical section and a through hole section arranged from the inside to the outside, an internal thread for connecting the nozzle body is provided on the inner wall of the cylindrical section, a spiral water groove is provided on the inner wall of the conical section, the through hole is located at the bottom of the cone, and the outlet position of the flow channel deviates from the through hole position.

[0007] The flow channels are plural.

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

[0009] The nozzle body is provided with a groove and a sealing ring.

[0010] The through hole is a circular hole.

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

[0012] Another technical solution of the present invention is: a water flosser, comprising the water flosser nozzle as described above.

[0013] The technical effects of the present invention are as follows: first, the water from the flow channel of the nozzle body is flushed into the water tank on the conical inner wall of the nozzle, and rotates along with the spiral water tank. One or more streams of water form a rotating water column, which rushes out from the through hole, has a good flushing effect and greatly improves the experience. Secondly, the convergent flow channel allows the water to flow out at a faster flow rate and flush in the spiral water tank, which can improve the rotation effect of the water and obtain a better flushing effect and experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is an appearance diagram of the nozzle of the oral irrigator of the present invention.

[0015] Figure 2 It is a cross-sectional view of the nozzle of the oral irrigator of the present invention. DETAILED DESCRIPTION

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] See also Figure 1-2 The nozzle of the present invention is mainly composed of a nozzle body 10, two water flow channels 11 are arranged inside the nozzle body 10, and a nozzle 20 is arranged at the end of the nozzle body 10. The two water flows in the flow channel 11 are combined into one in the nozzle 20 until flowing out of the nozzle 20.

[0018] In order to produce the rotating effect of the water column, the nozzle 20 of the present invention is uniquely designed, including a cylindrical section 21 with internal threads from the inside to the outside, a conical section 22 and a cylindrical hole 23, the internal threads are screwed with 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, and the water outlets of the two water flow channels face the spiral water groove on the inner wall of the conical section 22. Under the influence of the spiral water groove, the two streams of water from the two water flow channels rotate and merge into one, and flow out from the round through hole 23 at the bottom of the cone. Due to the inherent characteristics of the rotating water column, the flushing effect is better and the experience is better. It should be noted that the deviation of the outlet position of the flow channel 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 convergence shape is formed, which allows the water to flow out at a faster flow rate and flush in the water tank of the conical section 22, thereby improving the rotation effect of the water and obtaining a better flushing 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, so that the water flow with a certain pressure does not flow through the threaded joint of the internal thread and the external thread.

[0021] A pit 24 is provided on the end face of the nozzle. When the water flosser is turned off, the remaining water adheres to the pit 24 due to the effect of surface tension and cannot come out, thus avoiding the trouble of wetting other places.

[0022] This embodiment is provided with two flow channels, but the technical solution is not limited thereto, and a plurality of flow channels may be provided in the nozzle body and combined into one in the nozzle.

[0023] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification 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 still fall within the scope of the technical solution of the present invention.
