[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0045] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0046] Figures 1 to 5An innovative nebulizer for drug delivery, as provided in this application embodiment, includes a housing 1, an electrical device 20, a nebulizing assembly 3, and a switch 5. The housing 1 has an axially extending mounting cavity; a partition plate 11 is provided within the mounting cavity to divide it into a first chamber 1a and a second chamber 1b; the peripheral wall of the housing 1 has a mist outlet 1c communicating with the first chamber 1a; the peripheral wall of the housing 1 has a switch groove 1d; the mist outlet 1c penetrates the bottom of the switch groove 1d; the electrical device 20 includes an electrical assembly 4 and an inner housing 2. The inner shell 2 is detachably housed in the second chamber 1b. The inner shell 2 has an electrical cavity, and the electrical component 4 is disposed in the electrical cavity. The atomizing component 3 is disposed in the first chamber 1a and is electrically connected to the electrical device 20. The atomizing component 3 has a spray nozzle, which is correspondingly arranged with the mist outlet 1c. The switch 5 is movably housed in the switch groove 1d. The switch 5 is movable to close and open the mist outlet 1c. The opening end of the first chamber 1a is provided with an inclined cut surface 12 to expose a portion of the atomizing component 3.

[0047] It is understandable that the atomizing component 3 and the electrical device 20 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 mist outlet 1c can be opened or closed by moving the switch 5 to prevent atomized gas from being ejected from the mist outlet 1c when not in use. 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.

[0048] Figures 1 to 5 As shown, the electrical device 20 includes an inner shell 2, an electrical component 4, and a conductive post 25. The inner shell 2 includes a support 23 and a cover 24, which together form an electrical cavity. The electrical component 4 includes a main board 41 and a battery cell 42 disposed within the electrical cavity. The main board 41 extends along the axial direction of the electrical cavity, and the battery cell 42 is located on one side of the main board 41 and is electrically connected to the main board 41. The main board 41 includes a main body 411 and a connecting part 412. The main body 411 is plate-shaped, and the connecting part 412 is connected to one end of the main body 411 near the cover 24, and the connecting part 412 is set at an angle to the main body 411. The conductive post 25 is installed on the connecting part 412, and the axial direction of the conductive post 25 is parallel to the main body 411. The conductive post 25 passes through the cover 24.

[0049] It is understandable that the inner shell 2 conceals the electrical components within the electrical cavity, serving a waterproof and protective function; the electrical components can be electrically connected to the atomizing assembly 3 via the conductive posts 25 passing through the cover 24. Furthermore, in this application, the main board 41 includes a main body 411 and a connecting part 412 arranged at an angle, thus allowing the conductive posts 25 to be arranged axially parallel to the main body 411. In this way, the conductive posts 25, axially passing through the cover 24, can be directly electrically connected to the atomizing assembly 3; this application achieves the goals of simplified structure, rational layout, and reduced volume.

[0050] In this embodiment, an insulating buffer is provided between the battery cell 42 and the main board 41 to provide insulation and buffering.

[0051] like Figure 3 As shown, in this embodiment, the connecting portion 412 is perpendicular to the main body portion 411. The connecting portion 412 is located on the side of the main body portion 411 facing the battery cell 42.

[0052] It is understandable that the connecting part 412 is arranged perpendicularly to the main body part 411, which facilitates the arrangement of the conductive post 25 with its axis parallel to the main body part 411 and improves assembly efficiency.

[0053] Compared to the overall flat body, the conductive post 25 is usually vertically connected to the body. Therefore, in order to achieve the electrical connection between the conductive post 25 and the atomizing head 31, other conductive structures need to be designed. However, this application can directly connect the atomizing head 31 to the body through the conductive post 25, which simplifies the structure, makes the layout more reasonable, and achieves the goal of reducing the size.

[0054] like Figure 4 As shown, in the technical solution of this embodiment, an indicator light assembly is also included. The indicator light assembly includes an LED bead and a light shield 44. The LED bead is disposed on the main body 411. The light shield 44 is annular and is connected to the main body 411 and surrounds the LED bead.

[0055] Understandably, by setting up the light shield 44, the light scattered by the LED beads can be reduced, thus achieving the effect of focusing the light.

[0056] like Figure 4 As shown, in this embodiment, the LED bead is connected to the side of the main body 411 opposite to the battery cell 42. Thus, the light emitted by the LED bead directly shines onto the inner shell 2 and passes through the inner shell 2, serving an indicating function.

[0057] like Figure 3 As shown, in the technical solution of this embodiment, a counterweight 45 is also included. The counterweight 45 is disposed in the electrical cavity and located on the side of the battery cell 42 away from the motherboard 41.

[0058] It is understandable that the counterweight 45 is set to make the overall structure of the electrical device 20 more stable, especially after the electrical device 20 is applied to the nebulizer 100, so that it will not be top-heavy.

[0059] like Figure 3 As shown, the technical solution of this embodiment also includes a shock-absorbing sponge 46, which is located on the side of the counterweight 45 away from the battery cell 42 and covers the counterweight 45. In this way, it can play a role in shock absorption and protection.

[0060] In this embodiment, an isolation plate is provided inside the electrical cavity, and the electrical component 4 and the counterweight 45 are located on opposite sides of the isolation plate. This prevents the counterweight 45 from affecting the electrical component 4.

[0061] like Figure 1 and Figure 2 As shown, the cover 24 of the electrical device 20 faces the partition plate 11, and the conductive post 25 passes through the partition plate 11; the atomizing component 3 is disposed in the first chamber 1a and is electrically connected to the electrical component 4 through the conductive post 25.

[0062] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, a booster protrusion 51 is provided on the side of the switch key 5 away from the bottom of the switch groove 1d. The side of the booster protrusion 51 away from the key 5 is located inside the switch groove 1d or flush with the opening of the switch groove 1d.

[0063] Understandably, the switch 5 and the push-pull protrusion 51 are both housed within the switch recess 1d and do not protrude beyond the outer casing 1 from the opening of the switch recess 1d. This effectively conceals the switch 5 and reduces the likelihood of accidental activation, thus preventing accidental touches. Simultaneously, the push-pull protrusion 51 facilitates user operation, allowing the user to move the switch 5 by pushing it.

[0064] like Figure 2 , Figure 6 and Figure 7As shown, in the technical solution of this embodiment, the switch 5 includes a first damping member 52 and an outer cover 53. The first damping member 52 is movably connected to the switch groove 1d. The outer cover 53 is disposed on the side of the first damping member 52 away from the bottom of the switch groove 1d. The outer cover 53 is provided with a first mounting groove facing the first damping member 52, and the first damping member 52 is inserted into the first mounting groove. The outer cover 53 is provided with the booster protrusion 51 on the side away from the first damping member 52.

[0065] It is understandable that by setting the first damping element 52, the resistance during the movement of the switch 5 can be increased. On the one hand, the user can get force feedback when pushing the switch 5. On the other hand, the switch 5 can be prevented from sliding freely. The switch 5 can only be pushed when subjected to a certain force, which also serves to prevent accidental touch.

[0066] Meanwhile, the first assembly slot provides a basis for assembly positioning, improving the assembly efficiency of switch 5.

[0067] like Figure 6 , Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, the first damping member 52 is provided with a limiting strip groove 52a, and the bottom of the switch groove 1d is provided with a limiting boss 14, which passes through the limiting strip groove 52a.

[0068] Understandably, during the movement of the switch 5, the limiting boss 14 and the first damping element 52 move relative to each other. The cooperation between the limiting boss 14 and the limiting groove 52a can limit the displacement of the switch 5.

[0069] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, the limiting boss 14 is provided with a second assembly groove 14a on the side facing the outer cover 53, and a second damping member 54 is provided in the second assembly groove 14a, and the second damping member 54 abuts against the outer cover 53.

[0070] Understandably, the second mounting slot 14a provides a mounting and positioning base for the second damping element 54, and the second damping element 54 further increases the resistance encountered by the switch 5 during its movement, thereby further preventing accidental activation.

[0071] like Figure 2 , Figure 6 , Figure 7As shown, in this embodiment, the second damping member 54 is connected and fixed to the limiting boss 14 by a fastener 55. This improves the positional stability of the second damping member 54 and prevents it from moving with the switch 5.

[0072] In the technical solution of this embodiment, the two opposite groove walls of the switch groove 1d are respectively provided with snap-fit ​​sliding grooves, and the two opposite side walls of the outer cover 53 are snap-fitted with the snap-fit ​​sliding grooves; the snap-fit ​​sliding grooves extend along the moving direction of the switch 5.

[0073] Understandably, the locking groove serves to lock and limit the switch 5, preventing it from detaching from the housing 1. The switch 5 moves along the direction defined by the locking groove.

[0074] like Figure 2 , Figure 6 , Figure 7 As shown, the technical solution of this embodiment also includes a switch magnet 56, which is disposed on the first damping member 52; a Hall sensor is provided inside the housing 1, which is used to detect the position of the switch magnet 56 in order to control the mist outlet 1c.

[0075] Understandably, when the Hall sensor detects that the switch magnet 56 has reached the first preset position, it indicates that the switch 5 has moved to open the mist outlet 1c. The Hall sensor controls the atomizing assembly 3 to operate via the electrical device 20, and atomized gas is sprayed from the mist outlet 1c. When the Hall sensor detects that the switch magnet 56 has reached the second preset position, it indicates that the switch 5 has moved and closed the mist outlet 1c. The Hall sensor controls the atomizing assembly 3 to shut down via the electrical device 20, stopping the spraying of atomized gas from the mist outlet 1c.

[0076] In this embodiment, the switch magnet 56 is positioned corresponding to the second chamber 1b. This facilitates magnetic field sensing detection between the Hall sensor and the switch magnet 56.

[0077] Understandably, the partition plate 11 separates the atomizing component 3 and the electrical component 4 into two different chambers, serving a waterproof function.

[0078] like Figure 1 and Figure 2As shown, in this embodiment, the atomizing component 3 includes an atomizing head 31 and a liquid bottle 32. The atomizing head 31 is housed within 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 atomizing head 31 is provided with the spray nozzle and is electrically connected to the electrical device 20. 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.

[0079] Figures 1 to 8 As shown, in this embodiment, the inner shell 2 is detachably accommodated in the second chamber 1b; the outer wall of the inner shell 2 is provided with a snap-fit ​​protrusion 21, which engages with the snap-fit ​​groove 1e. 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 within 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 engagement of the snap-fit ​​groove 1e and the snap-fit ​​protrusion 21 ensures the inner shell 2 is stably fixed within the second chamber 1b. 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.

[0080] The first chamber 1a is used to accommodate the atomizing component 3; the opening end of the first chamber 1a is provided with an inclined cut surface 12 to expose a portion of the atomizing component 3; the cavity wall of the second chamber 1b is provided with a snap-fit ​​groove 1e.

[0081] Thus, the inclined cut surface 12 exposes the liquid bottle 32, facilitating user disassembly of the device. Furthermore, the outer and inner shell design in this embodiment significantly reduces the impact on the electrical components 4 within the inner shell 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.

[0082] In this embodiment, a magnetic magnet 26 is provided on the side of the inner shell 2 facing the partition plate 11, and a magnetic 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 magnetic magnets 26.

[0083] like Figure 1 As 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.

[0084] like Figure 1 , Figure 5 , Figure 7 and Figure 8 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.

[0085] 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.

[0086] In other embodiments, the outer shell 1 may also be made of a non-transparent material.

[0087] like Figure 1 and Figure 5 As shown in the technical solution of this embodiment, the inner shell 2 is made of an opaque material.

[0088] 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.

[0089] 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.

[0090] It is understandable that the electrical components and the atomizing head 31 are electrically connected by setting through holes.

[0091] like Figure 2 and Figure 6 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.

[0092] It is understandable that the sealing ring 22 can serve as a seal for waterproofing.

[0093] like Figure 2 and Figure 6 As shown, in the technical solution of this embodiment, the support 23 is provided with an assembly cavity for accommodating the electrical component 4; the cover 24 is provided 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.

[0094] Understandably, the installation of the mounting base and cover 24 facilitates the installation of the electrical components 4.

[0095] like Figure 5 and Figure 8 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.

[0096] 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.
