Therefore, the exemplary term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatially relative descriptors used in the text are interpreted accordingly.

[0043] Figures 1 to 6An atomizing head assembly provided by an embodiment of the present application includes a mounting base 1, an atomizing member 2, and a nozzle 3. One end of the mounting base 1 is used to connect to an external component, and the other end has a first groove 11. A positioning boss 12 is provided in the first groove 11; the positioning boss 12 has a second groove 13, and a mounting table 14 is provided in the second groove 13; a liquid guiding hole 15 is provided on the mounting table 14, and the liquid guiding hole 15 penetrates through the mounting base 1. The liquid guiding hole 15 is used to pass through a liquid guiding rod 5; wherein, a positioning groove 16 is provided at the upper end of the positioning boss 12; the atomizing member 2 is arranged on the mounting table 14 and corresponds to the liquid guiding hole 15; the nozzle 3 is connected to the mounting base 1, and the atomizing member 2 is located between the nozzle 3 and the mounting base 1; a positioning ring 31 protrudes from one side of the nozzle 3, and the positioning ring 31 has a third groove 32.

[0044] It can be understood that through the cooperation of the positioning groove 16 and the positioning ring 31, the quick assembly and positioning of the nozzle 3 and the mounting base 1 are realized. At the same time, the atomizing member 2 is restricted between the mounting table 14 and the nozzle 3, and the atomizing member 2 is located within the positioning ring 31, so that the atomized steam formed at the atomizing member 2 can be sprayed through the spraying channel 35. When the atomizing head assembly of the present application is applied to an atomizing tube device, the mounting base 1 is detachably connected to the liquid storage chamber 4. Thus, when the liquid in the liquid storage chamber 4 is used up, a new liquid storage chamber 4 can be directly replaced; in the present application, by providing the mounting base 1, the independence of the atomizing head assembly can be realized. The user only needs to replace the new liquid storage chamber 4 without having to repurchase the whole nasal care device product, which can improve the user experience.

[0045] Wherein, the settings of the first groove 11 and the second groove 13 can, on the one hand, play a role in reducing the weight of the mounting base 1, and on the other hand, can also play a role in buffering the vibration noise of the atomizing member 2.

[0046] Wherein, the mist guiding boss 33 protrudes and extends to the position of the atomizing member 2, which can smoothly guide the atomized steam to be sprayed and prevent the atomized steam from diffusing to other positions in the nozzle 3.

[0047] Such as Figure 4 and Figure 5As shown, in the technical solution of this embodiment, the part of the mounting base 1 facing away from the nozzle 3 is defined as an assembly boss 17. The assembly boss 17 is provided with a threaded hole 170 for threaded connection with an external component and for passing through the liquid guide rod 5. The aperture of the threaded hole 170 is larger than the aperture of the liquid guide hole 15.

[0048] It can be understood that the threaded connection with the external component is achieved through the threaded hole 170. When applied to the atomization tube device, one end of the liquid storage chamber 4 is provided with an external thread and is threadedly connected to the assembly boss 17. The liquid guide rod 5 in the liquid storage chamber 4 extends from the end where the external thread is located. When the liquid storage chamber 4 is assembled with the assembly boss 17, the liquid guide rod 5 is inserted into the threaded hole 170 and extends deep into the liquid guide hole 15. The liquid guide rod 5 guides the liquid in the liquid storage chamber 4 to the atomization member 2 and is atomized into atomized vapor at the position of the atomization member 2.

The piezoelectric ceramic 22 is electrically connected to the conductive column 18 through a wire.

[0053] As Figure 1As shown, in the technical solution of this embodiment, the cross-sectional dimension of the spray channel 35 gradually increases from the end close to the mounting base 1 to the end far from the mounting base 1. With such a design, the hole wall of the spray channel 35 will not hinder the smooth ejection of the atomized steam.

[0054] In the technical solution of this embodiment, the outer diameter range of the ejection boss 34 is 0.8 - 1.2 cm.

[0055] It can be understood that when the nasal care device is in use, the ejection boss 34 is aligned with the nose, and can even be inserted into the nose for use. Setting the outer diameter of the ejection boss 34 in the range of 0.8 - 1.2 cm can be inserted into the nasal cavity without being too large to cause discomfort.

[0057] It can be understood that the outer periphery of the end of the ejection boss 34 facing away from the mounting base 1 is defined as the nozzle section 36, and designing the nozzle section 36 as an arc can improve the comfort of use.

[0058] As Figure 1 、 Figure 2 and Figure 6 As shown, in the technical solution of this embodiment, a lifting boss 37 protrudes from the outer periphery of the nozzle 3, and the lifting boss 37 extends circumferentially around the outer periphery of the nozzle 3.

[0059] It can be understood that by providing the lifting boss 37, it is convenient to pull the atomizing head, and it is convenient to take out and put in the atomizing tube device from the housing of the nasal care device.

[0060] As Figure 1 、 Figure 2 and Figure 6 As shown, in the technical solution of this embodiment, a smooth transition is formed from the outer periphery of the ejection boss 34 to the lifting boss 37. With such a design, on the one hand, the appearance beautification degree can be improved, and on the other hand, the comfort of use can be improved.
