Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The present invention discloses an atomizing nozzle. Figure 1-9 As shown, it comprises: a nozzle body 10, a circulation channel 11 is provided in the nozzle body 10 for accommodating the flushing liquid for circulation, one end of the nozzle body 10 is set as a water inlet end 12, and the other end of the nozzle body 10 is set as a water outlet end 13;

[0033] The water outlet end 13 is provided with a detachably connected nozzle cover 20, which has an inner cavity 21 and an atomization hole 22 communicating with the inner cavity 21. The outer wall of the water outlet end 13 is provided with a plurality of atomization grooves located in the inner cavity 21, which are respectively communicated with the circulation channel 11 and the atomization hole 22.

[0034] It should be noted that the outer wall of the water outlet 13 is provided with an atomizing groove located within the inner cavity 21. The atomizing groove is respectively connected to the circulation channel 11 and the atomizing hole 22, thereby providing an atomizing nozzle. Due to the atomizing effect of the atomizing groove, the flushing liquid enters the circulation channel 11 from the water inlet 12, passes through the circulation channel 11, enters the multiple atomizing grooves on the outer wall of the water outlet 13, and converges at the atomizing hole 22. The liquid is sprayed out by pressure to form an atomized spray effect, which reduces the impact force of the flushing liquid and achieves gentle cleaning. At the same time, this structure can be used in cleaning equipment such as tooth irrigators and nasal washers, and can be compatible with various equipment models.

[0035] like Figure 7 and Figure 8 As shown, each atomization groove includes a water through groove 131 and a spiral guide groove 132. Multiple water through grooves 131 are arranged at intervals on the side wall of the water outlet end 13, and multiple spiral guide grooves 132 are arranged on the end surface of the water outlet end 13; one end of the water through groove 131 is connected to the circulation channel 11, and the other end of the water through groove 131 is connected to the spiral guide groove 132.

[0036] like Figure 7 and Figure 8As shown, a plurality of water-through grooves 131 are evenly spaced on the sidewall of the water outlet 13, and a plurality of spiral guide grooves 132 are interconnected and centrally symmetrically distributed on the end surface of the water outlet 13. In this embodiment, the number of water-through grooves 131 is set to three, and the number of spiral guide grooves 132 is set to three.

[0037] It should be noted that after the atomizing nozzle is connected to the water pump to supply the flushing liquid, the flushing liquid enters the water channel 131. Due to the sharp decrease in the outflow cross-sectional area, energy is stored and pressurized, and the pressure increases sharply. The water flow forms a rotating turbulent flow in the spiral guide groove 132, and then forms a water mist with an atomization effect through the micro atomizing hole 22.

[0038] like Figure 3 、 Figure 4 and Figure 9 As shown, the atomizing hole 22 includes a first hole segment 221 and a second hole segment 222, which are arranged from the inside out. The first hole segment 221 is a circular hole, and the second hole segment 222 is a conical hole. The aperture of the first hole segment 221 ranges from 0.15 to 0.25 mm. It should be noted that the circular hole of the first hole segment 221 and the conical hole of the second hole segment 222 facilitate the rapid ejection of the atomized flushing liquid.

[0039] like Figure 3 and Figure 4 As shown, the end surface of the water outlet 13 is closely fitted with the wall surface of the inner cavity 21. It should be noted that since the end surface of the water outlet 13 is closely fitted with the wall surface of the inner cavity 21, the flushing liquid in the atomizing tank is ensured to move along the direction of the tank opening and be smoothly atomized.

[0040] like Figure 5-8 As shown, the water outlet 13 is provided with a mounting groove 133, and the mounting groove 133 is provided with a sealing ring 30 that abuts the inner wall of the inner cavity 21. In the specific implementation process, the sealing ring 30 is set in an O shape and is made of elastic material, such as silicone, rubber, etc.

[0041] like Figure 5-8 As shown, the nozzle cover 20 is threadedly connected to the water outlet 13. In a specific implementation, the nozzle cover 20 is provided with an internal thread 211 located in the inner cavity 21, and the outer wall of the water outlet 13 is provided with an external thread 134 threadedly matched with the internal thread 211.

[0042] like Figure 5-8As shown, the nozzle body 10 is provided with a locking buckle 14, and the nozzle cover 20 is provided with a locking groove 23 adapted to fit the locking buckle 14. In a specific embodiment, there are two locking buckles 14, which are relatively distributed on the nozzle body 10; there are two locking grooves 23, which are relatively distributed on the nozzle cover 20. One end of the locking buckle 14 is provided with a blocking surface 141, and the locking buckle 14 is provided with an inclined surface to facilitate the insertion of the locking buckle 14 into the locking groove 23. The inclined surface allows the nozzle cover 20 to be threaded onto the nozzle body 10. When the nozzle cover 20 is rotated and installed past the inclined surface, the locking buckle 14 can be smoothly inserted into the locking groove 141.

[0043] It should be noted that when the anti-trip buckle 14 is buckled with the buckle groove 23, the end face of the water outlet end 13 fits tightly with the wall of the inner cavity 21. Since water can only flow along the water groove 131 and the spiral guide groove 132, and is atomized and sprayed out from the atomization hole 22, the nozzle cover 20 can be installed in place; when the nozzle cover 20 is rotated and installed on the nozzle body 10, the anti-trip buckle 14 is embedded in the buckle groove 23. Due to the blocking effect of the blocking surface 141, the nozzle cover 20 can be prevented from rotating in the opposite direction, thereby preventing the nozzle cover 20 from rotating when the atomizing nozzle is in use, thereby ensuring that the atomizing function of the atomizing nozzle is implemented normally.

[0044] like Figure 1-8 As shown, the outer wall of the nozzle body 10 is provided with a slot 15 for snap-fitting the atomizing nozzle. It should be noted that the slot 15 is arranged in an annular shape, and the arrangement of the slot 15 facilitates snap-fitting and mounting the atomizing nozzle on a cleaning device, which can be a cleaning device such as a water flosser or a nasal washer.

[0045] Working Principle: The outer wall of the water outlet 13 is provided with an atomizing groove located within the inner cavity 21. The atomizing groove is connected to the circulation channel 11 and the atomizing hole 22, respectively, thus providing an atomizing nozzle. Due to the atomizing effect of the atomizing groove, the irrigating liquid enters the circulation channel 11 from the water inlet 12, passes through the circulation channel 11, enters the multiple atomizing grooves on the outer wall of the water outlet 13, and converges at the atomizing hole 22. The pressure is ejected to form an atomized spray, reducing the impact force of the irrigating liquid, thereby achieving gentle cleaning. At the same time, this structure can be used with cleaning equipment such as tooth irrigators and nasal washers, and can be compatible with various equipment models.

[0046] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
