[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. For the sake of simplicity, the description below of a particular embodiment or example does not necessarily include all features of the present application. Indeed, some implementations of the present application can lack some or all of the features described below. In addition, the description below of a particular example does not necessarily mean that the present application is limited to that particular example. Furthermore, the description below of a particular example does not necessarily mean that the present application is limited to that particular example. Moreover, the present application can be practiced in different embodiments or examples than those described below.

[0042] For the sake of description, spatial relative terms can be used herein to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.

[0043] Figures 1 to 5 An electrical device 20 of an atomizing drug delivery instrument provided for an embodiment of the present application, comprising an inner shell 2, an electrical assembly 4 and a conductive column 25, the inner shell 2 comprising a bearing seat 23 and a cover 24, the cover 24 and the bearing seat 23 enclosing an electrical cavity; the electrical assembly 4 comprising a main board 41 and a battery core 42 arranged in the electrical cavity, the main board 41 extending along the axial direction of the electrical cavity, the battery core 42 being located on one side of the main board 41 and electrically connected with the main board 41; the main board 41 comprising a main body part 411 and a connecting part 412, the main body part 411 being plate-shaped, the connecting part 412 being connected to one end of the main body part 411 close to the cover 24, and the connecting part 412 and the main body part 411 being arranged at an included angle; the conductive column 25 being installed on the connecting part 412, and the axial direction of the conductive column 25 being parallel to the main body part 411; the conductive column 25 being arranged through the cover 24.

[0044] 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.

[0045] In this embodiment, an insulating buffer is provided between the battery cell 42 and the main board 41 to provide insulation and buffering.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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 housing 1, an electrical device 20 for the nebulizer drug delivery device as described above, and a nebulizer assembly 3: the housing 1 has an axial mounting cavity penetrating the housing 1; a partition plate 11 is provided in the mounting cavity to divide the mounting cavity into a first chamber 1a and a second chamber 1b; the side wall of the first chamber 1a is provided with a mist outlet 1c communicating with the first chamber 1a; the electrical device 20 for the nebulizer drug delivery device as described above is disposed in the second chamber 1b; the cover 24 of the electrical device 20 is disposed facing the partition plate 11, and a conductive post 25 passes through the partition plate 11; the nebulizer assembly 3 is disposed in the first chamber 1a and is electrically connected to the electrical device 4 through the conductive post 25; the nebulizer assembly 3 has a spray nozzle, and the spray nozzle is correspondingly disposed with the mist outlet 1c.

[0057] The specific structure of the electrical device of the nebulizer is as described in the above embodiments. Since the nebulizer 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0058] 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 set in the electrical cavity of the inner shell 2. The inner shell 2 provides further protection for the electrical component 4. This application has high waterproof performance and is safer.

[0059] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, in the technical solution of this embodiment, a switch 5 is also included. The outer peripheral wall of the housing 1 is provided with a mist outlet 1c and a switch groove 1d. The mist outlet 1c penetrates the bottom of the switch groove 1d. The switch 5 is movably accommodated in the switch groove 1d. The switch 5 can be moved to close and open the mist outlet 1c. A booster protrusion 51 is provided on the side of the switch 5 away from the bottom of the switch groove 1d. The side of the booster protrusion 51 away from the switch 5 is located in the switch groove 1d or flush with the opening of the switch groove 1d.

[0060] Understandably, the switch 5 and the booster protrusion 51 are both housed within the switch recess 1d and do not protrude from the main body at 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 booster protrusion 51 facilitates user operation, allowing the user to move the switch 5 by pushing it.

[0061] like Figure 2 , Figure 6 and Figure 7 As 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.

[0062] 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.

[0063] Meanwhile, the first assembly slot provides a basis for assembly positioning, improving the assembly efficiency of switch 5.

[0064] 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.

[0065] 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.

[0066] As Figure 2 , Figure 6 , Figure 7 and Figure 8 shown, in the technical scheme of the embodiment, the side of the limiting boss 14 facing the outer cover 53 is provided with a second assembly groove 14a, the second assembly groove 14a is provided with a second damping piece 54, and the second damping piece 54 abuts against the outer cover 53.

[0067] It can be understood that the second assembly groove 14a provides a mounting and positioning basis for the second damping piece 54, and the second damping piece 54 further increases the resistance received by the key 5 during movement, thereby further preventing accidental touch.

[0068] As Figure 2 , Figure 6 , Figure 7 shown, in the technical scheme of the embodiment, the second damping piece 54 is connected and fixed with the limiting boss 14 through a fastener 55. In this way, the position stability of the second damping piece 54 can be improved, and the second damping piece 54 can be prevented from moving with the key 5.

[0069] In the technical scheme of the embodiment, two opposite groove walls of the switch groove 1d are respectively provided with clamping sliding grooves, and two opposite side walls of the outer cover 53 are clamped and matched with the clamping sliding grooves; the clamping sliding grooves extend along the movement direction of the key 5.

[0070] It can be understood that the clamping sliding grooves clamp and limit the key 5, thereby preventing the key 5 from falling off the body. The key 5 moves along the direction defined by the clamping sliding grooves.

[0071] As Figure 2 , Figure 6 , Figure 7 shown, in the technical scheme of the embodiment, a switch magnet 56 is further included, the switch magnet 56 is arranged in the first damping piece 52; a Hall sensor is arranged in the body, and the Hall sensor is used to detect the position of the switch magnet 56 to control the mist outlet 1c to emit mist.

[0072] It can be understood that when the Hall sensor detects that the switch magnet 56 reaches a first preset position, it indicates that the key 5 moves to open the mist outlet 1c, the Hall sensor controls the atomization assembly 3 to work through the electrical device 20, and atomized gas is sprayed from the mist outlet 1c. When the Hall sensor detects that the switch magnet 56 reaches a second preset position, it indicates that the key 5 moves and closes the mist outlet 1c, and the Hall sensor controls the atomization assembly 3 to shut down through the electrical device 20, and stops spraying atomized gas from the mist outlet 1c.

[0073] In the embodiment, the switch magnet 56 is arranged corresponding to the second chamber 1b. The magnetic field between the Hall sensor and the switch magnet 56 is inductively detected.

[0074] It can be understood that the atomization assembly 3 and the electrical assembly 4 are separated in two different chambers by the partition plate 11, which plays a waterproof role.

[0075] As shown in Figure 1 and Figure 2 In the technical scheme of the embodiment, the atomization assembly 3 includes an atomization head 31 and a liquid containing bottle 32. The atomization head 31 is accommodated in the first chamber 1a, and the liquid containing bottle 32 is detachably connected to the side of the atomization head 31 away from the partition plate 11. The atomization head 31 is provided with the spray port, and the atomization head 31 is electrically connected with the electrical device 20. The liquid containing bottle 32 contains liquid, and the atomization head 31 can atomize the liquid, which is then sprayed out through the spray port of the atomization head 31 and the mist outlet 1c of the shell 1. When used by a user, the mist outlet 1c can correspond to the human body part that needs to be atomized.

[0076] Figures 1 to 8 As shown in, in the technical scheme of the embodiment, the inner shell 2 is detachably accommodated in the second chamber 1b. The outer wall surface of the inner shell 2 is provided with a clamping protrusion 21, and the clamping protrusion 21 is clamped and matched with the clamping groove 1e. It can be understood that the atomization assembly 3 and the electrical assembly 4 are separated in two different chambers by the partition plate 11, and the electrical assembly 4 is arranged in the electrical cavity of the inner shell 2, which further protects the electrical assembly 4. The waterproof performance of the present application is high, and it is safer. At the same time, the cooperation of the clamping groove 1e and the clamping protrusion 21 realizes the purpose of stably fixing the inner shell 2 in the second chamber 1b. In addition, the inclined surface 12 is arranged at the opening end of the first chamber 1a, so that part of the atomization assembly 3 is exposed outside the shell 1, which is convenient for operating the atomization assembly 3.

[0077] The first chamber 1a is used for accommodating the atomization assembly 3. The opening end of the first chamber 1a is provided with an inclined surface 12 for exposing part of the atomization assembly 3. The cavity wall of the second chamber 1b is provided with a clamping groove 1e.

[0078] In this way, the inclined surface 12 is arranged to expose the liquid containing bottle 32, which is convenient for the user to detach the liquid containing bottle 32. In addition, the arrangement of the shell and the inner shell in the embodiment can greatly reduce the influence on the electrical assembly 4 in the inner shell 2 if liquid leakage occurs when the user detaches the liquid containing bottle 32. At the same time, the user can easily pour out the liquid leaked into the first chamber 1a.

[0079] In the embodiment, the inner shell 2 is provided with a magnetic iron 26 on the side facing the partition plate 11, and the atomizing head 31 is also provided with a magnetic iron 26 on the side facing the partition plate 11, so that the atomizing head 31 can be stably installed through the magnetic attraction between the two magnetic irons 26.

[0080] As shown in Figure 1 , in the technical scheme of the embodiment, the number of the clamping protrusions 21 is two, which are located on two opposite outer wall surfaces of the inner shell 2. In this way, the connection stability of the inner shell 2 and the outer shell 1 can be improved.

[0081] As shown in Figure 1 , Figure 5 , Figure 7 and Figure 8 , in the technical scheme of the embodiment, the clamping groove 1e is arranged close to the open end of the second cavity 1b. The clamping protrusion 21 is correspondingly arranged at a position of the inner shell 2 away from the partition plate 11. It can be understood that after the inner shell 2 is inserted into the second cavity 1b in place, the clamping groove 1e and the clamping protrusion 21 cooperate to achieve the purpose of smooth assembly.

[0082] As shown in Figure 1 , in the technical scheme of the embodiment, the outer shell 1 is made of transparent material. In this way, the purpose of beautiful appearance and convenient observation of the situation in the first cavity 1a and the second cavity 1b can be achieved. For example, when water leakage in the first cavity 1a is observed, it can be poured out in time.

[0083] In other embodiments, the outer shell 1 can also be made of non-transparent material.

[0084] As shown in Figure 1 and Figure 5 , in the technical scheme of the embodiment, the inner shell 2 is made of non-transparent material.

[0085] It can be understood that the inner shell 2 is made of non-transparent material, which can visually cover the electrical components 4 in the electrical cavity and play a role in beautifying the appearance.

[0086] In the technical scheme of the embodiment, the partition plate 11 is provided with a through hole for penetrating the conductive column 25, and the electrical components 4 and the atomizing assembly 3 are electrically connected through the conductive column 25.

[0087] It can be understood that the through hole is arranged to realize the electrical connection between the electrical components and the atomizing head 31.

[0088] As shown in Figure 2 and Figure 6 , in the technical scheme of the embodiment, a sealing ring 22 is further included, which is located in the second cavity 1b and corresponds to the through hole.

[0089] It can be understood that the sealing ring 22 can play a sealing waterproof role.

[0090] As shown in Figure 2 and Figure 6 In the technical scheme of the embodiment, the bearing seat 23 is provided with an assembly cavity for accommodating the electrical component 4; the cover 24 is arranged at the open end of the bearing seat 23 to enclose the electrical cavity; the conductive column 25 is arranged through the cover 24; and the sealing ring 22 is sleeved on the conductive column 25 and located between the cover 24 and the partition plate 11.

[0091] It can be understood that the bearing seat and the cover 24 are arranged to facilitate the installation of the electrical component 4.

[0092] As shown in Figure 5 and Figure 8 In the technical scheme of the embodiment, the side of the inner shell 2 facing the partition plate 11 is provided with a positioning groove 2b, the cavity wall of the second cavity 1b is provided with a positioning protrusion 13, and the positioning protrusion 13 is in positioning cooperation with the positioning groove 2b.

[0093] It can be understood that the positioning cooperation of the positioning groove 2b and the positioning protrusion 13 realizes the positioning cooperation of the inner shell 2 and the second cavity 1b, avoids the installation of the wrong orientation, and plays a foolproof role.
