[0039] Figures 1 to 4A housing structure for a nebulizer provided in this application includes an outer shell 1 and an inner shell 2. The outer shell 1 has an axial mounting cavity extending through it. A partition plate 11 is provided inside the mounting cavity to divide it into a first chamber 1a and a second chamber 1b. The side wall of the first chamber 1a has a mist outlet 1c communicating with it. The first chamber 1a is used to accommodate a nebulizer component 3. The opening end of the first chamber 1a has an inclined cut surface 12 to expose a portion of the nebulizer component 3. The wall of the second chamber 1b has a snap-fit ​​groove 1e. The inner shell 2 is detachably accommodated in the second chamber 1b and has an electrical cavity for accommodating an electrical component 4. The outer wall surface of the inner shell 2 has a snap-fit ​​protrusion 21 that engages with the snap-fit ​​groove 1e.

[0040] It is understood that the atomizing component 3 and the electrical component 4 are separated into two different chambers by the partition plate 11, and the electrical component 4 is located in the electrical cavity of the inner shell 2. The inner shell 2 provides further protection for the electrical component 4, resulting in high waterproof performance and enhanced safety. Simultaneously, the inner shell 2 is stably fixed within the second chamber 1b through the cooperation of the snap-fit ​​groove 1e and the snap-fit ​​protrusion 21. Furthermore, an inclined cut surface 12 is provided at the opening end of the first chamber 1a, allowing a portion of the atomizing component 3 to be exposed outside the outer shell 1, facilitating operation of the atomizing component 3.

[0041] The atomizing assembly 3 includes an atomizing head 31 and a liquid bottle 32. The atomizing head 31 is housed in the first chamber 1a, and the liquid bottle 32 is detachably connected to the side of the atomizing head 31 facing away from the partition plate 11. The liquid bottle 32 contains liquid, which the atomizing head 31 atomizes and then sprays out through the spray nozzle of the atomizing head 31 and the mist outlet 1c of the outer casing 1. When in use, the user can align the mist outlet 1c with the part of the body that needs atomization.

[0042] Thus, the inclined cut surface 12 exposes the liquid bottle 32, facilitating user disassembly of the device. Furthermore, the housing structure in this embodiment significantly reduces the impact on the electrical components 4 within the inner housing 2 should liquid leakage occur during disassembly of the liquid bottle 32. Simultaneously, the user can easily pour out any liquid that leaks into the first chamber 1a.

[0043] In this embodiment, a magnet 26 is provided on the side of the inner shell 2 facing the partition plate 11, and a magnet 26 is also provided on the side of the atomizing head 31 facing the partition plate 11. The atomizing head 31 can be stably installed through the mutual magnetic attraction of the two magnets 26.

[0044] like Figure 1As shown, in the technical solution of this embodiment, there are two snap-fit ​​protrusions 21, located on two opposite outer wall surfaces of the inner shell 2; thus, the connection stability between the inner shell 2 and the outer shell 1 can be improved.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the snap-fit ​​groove 1e is positioned near the opening of the second chamber 1b. The snap-fit ​​protrusion 21 is correspondingly positioned on the inner shell 2 away from the partition plate 11. It is understood that after the inner shell 2 is inserted into the second chamber 1b, the snap-fit ​​groove 1e and the snap-fit ​​protrusion 21 cooperate to achieve smooth assembly.

[0046] like Figure 1 As shown, in this embodiment, the outer shell 1 is made of a transparent material. This serves both aesthetic purposes and facilitates observation of the contents of the first chamber 1a and the second chamber 1b. For example, if water leakage is observed in the first chamber 1a, it can be emptied promptly.

[0047] In other embodiments, the outer shell 1 may also be made of a non-transparent material.

[0048] like Figure 1 and Figure 4 As shown in the technical solution of this embodiment, the inner shell 2 is made of an opaque material.

[0049] Understandably, the inner shell 2 is made of an opaque material, which can visually cover the electrical components 4 inside the electrical cavity, thus enhancing the appearance.

[0050] In the technical solution of this embodiment, the partition plate 11 is provided with a through hole for passing through the conductive post 25, and the electrical component 4 and the atomizing component 3 are electrically connected through the conductive post 25.

[0051] It is understandable that the electrical components are electrically connected to the atomizing head 31 by setting through holes.

[0052] like Figure 2 and Figure 4 As shown, the technical solution of this embodiment also includes a sealing ring 22, which is located in the second chamber 1b and is provided corresponding to the through hole.

[0053] It is understandable that the sealing ring 22 can serve as a seal for waterproofing.

[0054] like Figure 2 and Figure 4As shown, in the technical solution of this embodiment, the inner shell 2 includes a support 23 and a cover 24. The support 23 is provided with an assembly cavity for accommodating the electrical component 4. The cover 24 is disposed at the open end of the support 23 to enclose and form the electrical cavity. The conductive post 25 passes through the cover 24. The sealing ring 22 is sleeved on the conductive post 25 and is located between the cover 24 and the partition plate 11.

[0055] Understandably, the installation of the mounting base and cover 24 facilitates the installation of the electrical components 4.

[0056] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the inner shell 2 is provided with a positioning groove 2b on the side facing the partition plate 11, and the cavity wall of the second chamber 1b is provided with a positioning protrusion 13, which is positioned and engaged with the positioning groove 2b.

[0057] Understandably, the positioning groove 2b and the positioning protrusion 13 work together to achieve the positioning of the inner shell 2 and the second chamber 1b, thus preventing misalignment during installation and serving as a foolproof mechanism.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the outer peripheral wall of the outer shell 1 is also provided with a switch groove 1d, which is used to install the switch 5; the mist outlet 1c is provided corresponding to the switch groove 1d and is connected to it.

[0059] It is understandable that by setting the switch groove 1d to accommodate the switch 5, the size of the switch 5 protruding from the housing 1 can be reduced, or even the switch 5 can be completely accommodated within the switch groove 1d, thus reducing accidental activation.

[0060] On the other hand, such as Figure 1 and Figure 2 As shown, this application also provides a nebulizer drug delivery device 100, including a nebulizer component 3, an electrical component 4, and the housing structure of the nebulizer drug delivery device as described above. The specific structure of the housing structure of the nebulizer drug delivery device is as described in the above embodiments. Since the nebulizer drug delivery device 100 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, and will not be described in detail here. Among them, the nebulizer component 3 includes a nebulizer head 31 and a liquid bottle 32. The nebulizer head 31 is accommodated in the first chamber 1a, and the liquid bottle 32 is detachably connected to the side of the nebulizer head 31 away from the partition plate 11. The spray port of the nebulizer head 31 is correspondingly arranged and connected to the mist outlet 1c of the outer shell 1. The electrical component 4 is disposed in the electrical cavity and is electrically connected to the nebulizer head 31.

Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0062] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another.

Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0063] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those 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 invention.
