In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0029] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] like Figures 1-5 As shown, a device that can moisturize and filter nasal allergens includes a filter body 1 and a connector 2, and the two filter bodies 1 are connected by the connector 2; the filter body 1 includes an upper shell 11, a lower shell 12, a filter layer 13 and a moisturizing layer 14, the upper shell 11 and the lower shell 12 are connected, the lower shell 12 is hollow inside, the filter layer 13 is located in the lower shell 12, and the moisturizing layer 14 is wrapped around the outside of the filter body 1.

[0031] In use, the two filters 1 are inserted into the nasal cavity, and the connecting body 2 is hung on the nasal septum cartilage. When taking out, the connecting body 2 is pulled to pull out the two filters 1. The moisturizing layer 14 closely fits the nasal cavity, so that the gas passes through only the filter 1, and the gas passes through the filter layer 13, which can block various allergens. The device can effectively block allergens in the air and reduce nasal allergic symptoms. The device is simple in structure, easy to operate, and comfortable to wear. After the user wears the device, the nasal cavity can be moisturized and the allergens can be filtered through breathing.

[0032] As shown in Figure 2 , in this embodiment, the filter layer 13 is a filter membrane. The filter layer 13 is preferably a filter sheet capable of filtering PM2.5, which can effectively block fine particulate matter and allergens in the air.

[0033] As shown in Figure 2 , in this embodiment, the moisturizing layer 14 is a sponge material, which not only has good air permeability, but also can further adsorb allergens in the air while keeping the nasal cavity moist.

[0034] As shown in Figure 5 , in this embodiment, the upper shell 11 and the lower shell 12 are snap connected. The lower end of the upper shell extends a protruding portion, and the upper end of the lower shell is provided with a recessed portion. The protruding portion is inserted into the recessed portion and is automatically locked after being inserted into place, which can realize quick assembly and disassembly and facilitate replacement of the filter layer 13. In other embodiments, threaded connections and the like can also be used.

[0035] As shown in Figure 3 , in this embodiment, the upper shell 11 and the connecting body 2 are integrally formed. Integrally forming reduces processing and assembly procedures. The connecting body 2 is placed on the top of the upper shell 11, the filter 1 is inserted into the nasal cavity, and the upper shell 11 faces outward, so that the connecting portion does not touch the nose body and there is no uncomfortable feeling during use.

[0036] As shown in Figure 3 , in this embodiment, the connecting body 2 includes a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23. The first connecting portion 21 and the first connecting portion 21 are symmetrically arranged and connected by the third connecting portion 23. Among them, the first connecting portion 21 and the second connecting portion 22 respectively include a first arc portion 211 and a second arc portion 212. One end of the first arc portion 211 is connected with the second arc portion 212, the other end of the first arc portion 211 is connected with the upper shell 11, the center of the first arc portion 211 is located outside the connecting body 2, and the center of the second arc portion 212 is located inside the connecting body 2, so that the connecting body 2 can better fit the nasal septum cartilage when worn. The third connecting portion 23 is a straight line or an arc to adapt to the shape of the nasal septum cartilage of different users.

[0037] As shown in Figure 2As shown, in this embodiment, grilles 15 are provided inside the upper housing 11 and the lower housing 12, respectively, and the filter layer 13 is disposed between the grilles 15. The grilles 15 are used to secure the filter layer 13, ensuring that the filter layer 13 does not shift or fall off. The grilles 15 also do not block the flow of gas.

[0038] like Figure 2 As shown, in this embodiment, a circle of bosses 16 are provided on the outside of the bottom of the lower housing 12. These bosses 16 secure the position of the moisturizing layer 14, preventing the second filter 1 from sliding outside the lower housing 12. Furthermore, because the moisturizing layer 14 is made of a sponge material, which is fluffy and easily deformed, and the diameter of the sponge is slightly larger than the nasal cavity, it is difficult to insert. Therefore, the bosses 16 are provided on the lower housing 12 at an angle to facilitate smooth insertion of the filter 1 into the nasal cavity, improving the convenience of wearing.

[0039] A device that can moisturize and filter nasal allergens. A filter layer 13 is built into the lower housing 12. This filter layer filters particulate matter above PM2.5 while ensuring that normal ventilation is not affected. A moisturizing layer 14 is wrapped around the outer surface of the lower housing 12. This layer adheres perfectly to the inner wall of the nostrils, ensuring that air flows only through the filter layer 13, effectively blocking various allergens and achieving a relatively sealed effect. Furthermore, the moisturizing layer 14 also has a moisturizing function, helping to keep the nasal cavity moist.

[0040] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0041] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
