[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0046] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0047] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatially relative relationship terms are intended to include different orientations of the device in use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or movement state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" another element or feature will then be oriented as "above" or "over" the other element or feature. Therefore, the exemplary term "below" can include both the upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0048] Figures 1 to 10 A atomizing tube device provided for the embodiments of this application, the atomizing tube device includes a liquid chamber 4, a liquid guiding rod 5, and an atomizing head assembly 100. The liquid chamber 4 has a receiving cavity and an opening 40 communicating with the receiving cavity; a limiting groove 41 is provided on one side of the liquid chamber 4 close to the opening 40; the liquid guiding rod 5 passes through the opening 40 and extends into the receiving cavity; the atomizing head assembly 100 is detachably connected to the liquid chamber 4 and abuts against the liquid guiding rod 5; a limiting protrusion 10 is provided on the side of the atomizing head assembly 100 facing the liquid chamber 4, and the limiting protrusion 10 is in limiting cooperation with the limiting groove 41.

[0049] It can be understood that the accommodating cavity of the liquid storage chamber 4 can be used to accommodate liquid. The liquid guiding rod 5 guides the liquid in the accommodating cavity to the atomizing head assembly 100 for atomization and then ejection. When the atomizing head assembly 100 is connected to the liquid storage chamber 4, the connection stability can be improved by the limiting cooperation between the limiting protrusion 10 and the limiting groove 41, preventing relative movement between the atomizing head assembly 100 and the liquid storage chamber 4.

[0050] As Figures 1 to 4 shown, in the technical solution of this embodiment, the liquid storage chamber 4 includes a chamber body 42 and a connecting column 43. The chamber body 42 has the accommodating cavity; the connecting column 43 is arranged at one end of the chamber body 42. The connecting column 43 is provided with a first channel communicating with the accommodating cavity. The end of the first channel far from the chamber body 42 is the opening 40; the liquid guiding rod 5 is inserted through the first channel; an external thread is provided on the outer periphery of the connecting column 43; the outer peripheral dimension of the connecting column 43 is smaller than the outer peripheral dimension of the chamber body 42; the limiting groove 41 is provided on one side of the chamber body 42 facing the connecting column 43; a threaded hole 170 is provided on one side of the atomizing head assembly 100 facing the liquid storage chamber 4, and the atomizing head assembly 100 is threadedly connected to the connecting column 43.

[0051] It can be understood that the connection between the liquid storage chamber 4 and the atomizing head assembly 100 is realized by the threaded connection between the connecting column 43 and the atomizing head assembly 100, and the limiting effect is achieved after connection through the cooperation between the limiting protrusion 10 and the limiting groove 41. The limiting groove 41 is arranged on one side of the chamber body 42 facing the atomizing head assembly 100, which can realize the limiting cooperation while completing the threaded fit, simplifying the operation.

[0052] As Figure 4 shown, in the technical solution of this embodiment, a transition groove 44 is further provided on one side of the chamber body 42 facing the connecting column 43. The depression depth of the transition groove 44 is smaller than the depression depth of the limiting groove 41, and the transition groove 44 is connected to the limiting groove 41; the transition groove 44 and the limiting groove 41 are arranged along the threaded fit direction of the atomizing head assembly 100, so that the limiting protrusion 10 slides from the transition groove 44 into the limiting groove 41.

[0053] It can be understood that by providing the transition groove 44, it can prevent the limiting protrusion 10 from contacting the chamber body 42 before sliding into the limiting groove 41, avoiding wear of both the limiting protrusion 10 and the chamber body 42 caused by friction, and ensuring the smooth progress of assembly and reducing obstacles.

[0054] As Figure 4As shown, in the technical solution of this embodiment, a limit block 45 is further included, and the limit block 45 is arranged at a position of the transition groove 44 close to the limit groove 41, and the height of the limit block 45 is less than the recessed depth of the transition groove 44. Such a design can ensure that the limit groove 41 plays a limiting role.

[0055] like Figure 2 and Figure 4 As shown, in the technical solution of this embodiment, the number of the limiting protrusions 10 is two, the number of the limiting grooves 41 is two, the number of the transition grooves 44 is two, and the number of the limiting blocks 45 is two. In this way, the connection stability can be improved while achieving force balance.

[0056] like Figure 1 , Figure 2 and Figure 5 As shown, in the technical solution of this embodiment, the atomizer head assembly 100 includes a mounting seat 1, an atomizer 2 and a nozzle 3: the threaded hole 170 is provided on one side of the mounting seat 1, and a mounting platform 14 is provided on the other side of the mounting seat 1, and the mounting platform 14 is provided with a liquid guide hole 15, and the liquid guide hole 15 is connected to the threaded hole 170; the side of the mounting seat 1 away from the mounting platform 14 is provided with the limiting protrusion 10; the atomizer 2 is arranged on the mounting platform 14 and is arranged corresponding to the liquid guide hole 15; the liquid guide rod 5 is penetrated through the liquid guide hole 15 and abuts against the atomizer 2; the nozzle 3 is connected to the side of the mounting seat 1 away from the limiting protrusion 10, and the atomizer 2 is located between the nozzle 3 and the mounting seat 1; the nozzle 3 is provided with a spray channel 35, and the spray channel 35 is arranged corresponding to the atomizer 2.

[0057] It can be understood that a detachable connection is achieved between the mounting base 1 and the liquid tank 4 ; the liquid guide rod 5 guides the liquid in the liquid tank 4 to the position of the atomizer 2 , the atomizer 2 atomizes the liquid to form atomized vapor, and the atomized vapor is sprayed out from the spray channel 35 .

[0058] like Figure 1 As shown, in the technical solution of this embodiment, a stop ring 19 is provided at one end of the mounting seat 1 close to the nozzle 3 , and the stop ring 19 extends along the outer circumference of the mounting seat 1 .

[0059] It can be understood that when the atomizer tube device is installed on the shell 6 of the nose care instrument, the stop ring 19 abuts against the shell 6 to play a limiting role and at the same time indicates that the installation is in place.

[0060] like Figures 5 to 10As shown, in the technical solution of this embodiment, one end of the mounting seat 1 is connected to the liquid tank 4, and the other end has a first groove 11, and a positioning boss 12 is provided in the first groove 11; the positioning boss 12 has a second groove 13, and a mounting platform 14 is provided in the second groove 13; the mounting platform 14 is provided with a liquid guide hole 15, and the liquid guide hole 15 passes through the mounting seat 1, and a liquid guide rod 5 is passed through the liquid guide hole 15; wherein, a positioning groove 16 is provided at the upper end of the positioning boss 12; the atomizer 2 is arranged on the mounting platform 14, and is arranged corresponding to the liquid guide hole 15; the nozzle 3 is connected to the mounting seat 1, and the atomizer 2 is located at A positioning ring 31 is provided on one side of the nozzle 3, and the positioning ring 31 has a third groove 32, and a mist-inducing boss 33 is provided in the third groove 32; a spray boss 34 is provided on the other side of the nozzle 3, and the spray boss 34 is arranged corresponding to the mist-inducing boss 33; the spray boss 34 is provided with a spray channel 35, and the spray channel 35 passes through the spray boss 34 and the mist-inducing boss 33; wherein, the positioning ring 31 is positioned and matched with the positioning groove 16, and the mist-inducing boss 33 is arranged corresponding to the atomizing element 2, so as to spray the atomized vapor formed at the atomizing element 2 through the spray channel 35.

[0061] It is understandable that the nozzle 3 and the mounting seat 1 can be quickly assembled and positioned by the cooperation of the positioning groove 16 and the positioning ring 31, and the atomizer 2 is limited between the mounting platform 14 and the nozzle 3, and the atomizer 2 is located in the positioning ring 31, so that the atomized vapor formed at the atomizer 2 can be sprayed out through the spray channel 35. The mounting seat 1 is detachably connected to the liquid tank 4, so that when the liquid in the liquid tank 4 is used up, a new liquid tank 4 can be directly replaced; by setting the mounting seat 1, the independence of the atomizer head assembly can be achieved, and the user only needs to replace the new liquid tank 4 without repurchasing a full set of nasal care products, which can improve the user experience.

[0062] The provision of the first groove 11 and the second groove 13 can reduce the weight of the mounting base 1 on the one hand, and can also buffer the vibration noise of the atomizer 2 on the other hand.

[0063] The mist-inducing boss 33 is raised and extends to the position of the atomizing element 2 , which can smoothly guide the atomized steam to spray out and prevent the atomized steam from diffusing at other positions in the nozzle 3 .

[0064] like Figure 8 and Figure 9 As shown, in the technical solution of this embodiment, the portion of the mounting seat 1 that is away from the nozzle 3 is defined as an assembly boss 17, and the assembly boss 17 is provided with a threaded hole 170, and the threaded hole 170 is threadedly connected to the connecting column and the liquid guiding rod 5 is passed through it; the aperture of the threaded hole 170 is larger than the aperture of the liquid guiding hole 15.

[0065] It can be understood that the threaded connection with the connecting column is achieved through the threaded hole 170, one end of the liquid tank 4 is provided with an external thread, and is threadedly connected to the assembly boss 17, and the liquid guiding rod 5 in the liquid tank 4 extends from the end where the external thread is located. When the liquid tank 4 and the assembly boss 17 are assembled, the liquid guiding rod 5 is inserted from the threaded hole 170 and penetrates into the liquid guiding hole 15. The liquid guiding rod 5 guides the liquid in the liquid tank 4 to the position of the atomizer 2, and is atomized into atomized vapor at the position of the atomizer 2.

[0066] like Figure 9 As shown, in the technical solution of this embodiment, the outer peripheral surface of the assembly boss 17 includes an arc-shaped portion 171 and a flat portion 172, and the flat portion 172 and the side of the mounting seat 1 facing away from the nozzle 3 form a notch 173, and the mounting seat 1 is provided with a conductive hole 174 connected to the notch 173, and the conductive hole 174 connects the first groove 11 and the notch 173; a conductive column 18 is provided in the conductive hole 174, and the conductive column 18 is electrically connected to the atomizer 2.

[0067] It can be understood that, when the atomizer tube device is applied to the nasal care instrument, the flat surface portion 172 and the notch 173 on the mounting base 1 can correspond to the corresponding plane of the assembly cavity of the nasal care instrument, thereby achieving corresponding installation and stability after installation without rotation.

[0068] At the same time, the design of the space of the gap 173 can provide an escape space for the electrical connection between the atomizer 2 and the power supply, and the conductive column 18 can abut against the power supply sheet in the shell of the nasal care instrument.

[0069] like Figure 5 and Figure 8 As shown, in the technical solution of this embodiment, the atomizer 2 includes an atomizer sheet 21, a piezoelectric ceramic 22 and a silicone gel 23. The atomizer sheet 21 is arranged corresponding to the liquid guide hole 15, and the piezoelectric ceramic 22 is provided with a first through hole. The piezoelectric ceramic 22 is arranged on one side of the atomizer sheet 21, and the first through hole is arranged corresponding to the liquid guide hole 15; the silicone gel 23 is coated on the outer periphery of the atomizer sheet 21 and the piezoelectric ceramic 22; the piezoelectric ceramic 22 is electrically connected to the conductive column 18 through an electric wire.

[0070] It is understandable that the atomizing seat 21 provides a stable installation base for the atomizing sheet 25 to improve stability. The design of the installation groove 23 can limit the atomizing sheet 25.

[0071] like Figure 5As 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 impede the smooth ejection of the atomized vapor.

[0072] In the technical solution of this embodiment, the outer peripheral diameter range of the ejection boss 34 is 0.8 - 1.2 cm.

[0073] 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 peripheral diameter of the ejection boss 34 in the range of 0.8 - 1.2 cm can be inserted into the nasal cavity and will not be too large to cause discomfort.

[0074] Such as Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, the outer periphery of the end of the ejection boss 34 facing away from the mounting base 1 is arc-shaped.

[0075] It can be understood that defining the outer periphery of the end of the ejection boss 34 facing away from the mounting base 1 as the nozzle section 36 and designing the nozzle section 36 to be arc-shaped can improve the comfort of use.

[0076] Such as Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, a lifting boss 37 is convexly provided on the outer periphery of the nozzle 3, and the lifting boss 37 extends circumferentially around the outer periphery of the nozzle 3.

[0077] 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 nasal care device housing.

[0078] Such as Figure 5 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 beauty can be improved, and on the other hand, the comfort of use can be improved.

[0079] Such as Figure 5 As shown, in the technical solution of this embodiment, a contact convex ring 38 is further provided on the side of the nozzle 3 facing the mounting base 1; the contact convex ring 38 is sleeved on the positioning ring 31 and is spaced from the positioning ring 31; the contact convex ring 38 abuts against the peripheral edge of the mounting base 1; wherein, at least one magnet 39 is provided between the positioning ring 31 and the contact convex ring 38, and when the number of magnets 39 is multiple, the multiple magnets 39 are evenly distributed. Figure 10The case where two magnets 39 are provided is shown. In another embodiment, the number of magnets 39 can also be three. The specific number of magnets 39 is not limited herein, and providing one or more magnets 39 is within the protection scope of this application.

[0080] It can be understood that the abutting convex ring 38 abuts against the peripheral edge of the mounting seat 1 to seal the internal structure, serving as a partition, for protection, and for beautification. And providing the magnets 39 facilitates the connection between the atomizing head assembly 100 and the cap 7 of the nasal care device. When not in use, the cap 7 covers the nozzle 3, and the cap 7 is stably connected to the atomizing head assembly 100 by magnetism.

[0081] On the other hand, as Figure 11 shown, this application also provides a nasal care device, including a housing 6 and the atomizing tube device as described above. Since this nasal care device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the housing 6 has an assembly cavity; the liquid storage chamber 4 of the atomizing tube device is detachably installed in the assembly cavity.

[0082] As Figure 11 shown, in this embodiment, it further includes a cap 1, and the cap 1 is detachably connected to the housing 7 and can be used to cover and open the atomizing head assembly 100.
