Description

Technical Field

[0001] The utility model belongs to the technical field of household atomization treatment medical equipment, in particular to an atomization device and an atomizer. Background Art

[0002] Nebulizer inhalation therapy is an important and effective treatment for respiratory diseases. A nebulizer inhaler atomizes liquid medication into tiny particles, which are then inhaled into the respiratory tract and lungs, achieving painless, rapid, and effective treatment. Existing nebulizers (nebulizers) are categorized into two types: split-body nebulizers and integrated nebulizers. Split-body nebulizers have a separate mask and main unit, which delivers aerosolized medication to the mask via a pipe. Integrated nebulizers are mostly handheld and consist of a rigidly connected handheld nebulizer unit, a medicine cup, and a mask.

[0003] To make it easier for users to hold, the main unit of an integrated atomizer is typically designed in the shape of a column, with the mask typically extending radially outward from the circumference of the column. When using the atomizer, the user must hold the main unit and hold the mask over their mouth and nose, maintaining this position throughout the entire process. Some masks are equipped with straps that wrap around the user's head or ears to reduce the strain of holding the main unit for extended periods. However, because the main unit is positioned relatively forward and downward relative to the face, the strap alone cannot fully secure the atomizer to the user's face. This situation forces the user to maintain a hand-held grip on the main unit during use, and still does not free the user from holding the atomizer.

[0004] Reducing the overall size and / or weight of the nebulizer, or placing its center of gravity as close to the user's face as possible, can help maintain the nebulizer on the user's face using only the strap. However, the drug mist released by the nebulizer needs to travel a sufficient distance to diffuse to a state suitable for inhalation. If the nebulizer is too small, the drug mist may reach the user's mouth and nose before it has fully diffused, which is not conducive to inhalation and may also cause the user to feel uncomfortable being bombarded by the drug mist. Utility Model Content

[0005] The utility model aims to provide an atomizing device and an atomizer to solve the contradiction between the requirement for a small size of the atomizer and the need for sufficient space / distance for the diffusion of the medicine mist.

[0006] In a first aspect, an atomizing device is provided for converting liquid medicine into medicine mist. The atomizing device is a part of the atomizer and is electrically connected to the main unit of the atomizer.

The medicine cup has a chamber for containing liquid medicine, and a medicine outlet is provided at the bottom of the chamber. The medicine cup has a first surface, and the first surface faces the main unit when the atomizing device is installed in the atomizer. The atomizing plate assembly has an inner side and an outer side, and the inner side and the outer side are oriented in opposite directions. The inner side is used to receive liquid medicine, and the outer side is used to release medicine mist. The inner side is sealed to the medicine outlet of the chamber. The mist outlet pipe has a first end and a second end. The first end is sealed to the outer side of the atomizing plate assembly, and the second end forms the mist outlet. The mist outlet pipe is used to allow the medicine mist released by the atomizing plate assembly to pass through and enter the external environment. The first surface is provided with a recessed portion, the atomizing plate assembly is located in the recessed portion, and at least a portion of the mist outlet pipe is disposed in the recessed portion.

[0009] In combination with the above possible implementation manner, in another possible implementation manner, the recessed portion obliquely intersects with the first surface in a manner such that the top end of the recessed portion is further away from the first side of the medicine cup than the bottom end of the recessed portion.

[0010] In combination with the above possible implementation methods, in another possible implementation method, a blocking member is provided in the mist outlet pipe, and the blocking member forms at least one blocking portion with a predetermined distance from the inner wall of the mist outlet pipe in at least one cross section of the mist outlet pipe; the blocking member is located outside the spray path of the atomizer assembly.

[0013] In combination with the above possible implementations, in another possible implementation, the medicine cup further has a second surface, which is oriented opposite to the first surface. A perspective panel is provided on one side of the medicine cup corresponding to the second surface, and the perspective panel forms part of the wall of the chamber.

[0014] In combination with the above possible implementation manner, in another possible implementation manner, when viewed along the normal direction of the first surface, a partial area of ​​the atomizer assembly overlaps with the cavity of the medicine cup.

[0016] In the atomizer device, a recessed portion is provided on the first surface of the medicine cup, the atomizer assembly is located within the recessed portion, and at least a portion of the atomizer pipe is disposed within the recessed portion. While the overall length of the atomizer pipe remains unchanged, a section of the pipe is disposed within the recessed portion, thereby reducing the overall axial dimension of the atomizer pipe, equivalent to reducing the overall thickness of the atomizer device. Atomizers equipped with this atomizer device are more conducive to achieving lightweight and miniaturization. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0041] The features and exemplary embodiments of various aspects of the present disclosure will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present disclosure. However, it will be apparent to those skilled in the art that the present disclosure can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present disclosure by illustrating examples of the present disclosure.

[0042] Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present disclosure.

[0043] The atomizing device provided in the embodiment of the present disclosure is used to convert liquid medicine into medicine mist, and the atomizing device is part of the nebulizer. The atomizing device includes a medicine cup, an atomizing sheet assembly, and a mist outlet pipe. The medicine cup has a chamber for containing liquid medicine, and a medicine outlet is provided at the bottom of the chamber; the medicine cup has a first surface, and the first surface faces the main unit when the atomizing device is installed on the nebulizer. The atomizing sheet assembly has an inner side and an outer side, and the inner side is oriented in opposite directions to the outer side. The inner side is used to receive liquid medicine, and the outer side is used to release medicine mist, and the inner side is sealedly connected to the medicine outlet of the chamber. The mist outlet pipe has a first end and a second end, the first end is sealedly connected to the outer side of the atomizing sheet assembly, and the second end forms the mist outlet; the mist outlet pipe is used for allowing the medicine mist released by the atomizing sheet assembly to pass through and enter the external environment. Among them, the first surface of the medicine cup is provided with a recessed portion, the atomizing sheet assembly is located in the recessed portion, and at least a portion of the mist outlet pipe is provided in the recessed portion. While the overall length of the mist outlet pipe remains unchanged, a section of the pipe body is disposed in the recessed portion, thereby reducing the overall size of the atomizing device in the axial direction of the mist outlet pipe, which is equivalent to reducing the overall thickness of the atomizing device. An atomizer having such an atomizing device is more conducive to achieving lightweight / miniaturization.

[0044] The following describes the structure and function of the atomizer in combination with the overall structure of the atomizer. Figures 1 to 3 , Figure 1A schematic diagram of an atomizer provided according to one embodiment of the present disclosure. Figure 2 for Figure 1 Exploded view of the atomizer shown in . Figure 3 for Figure 1 A cross-sectional view of the atomizer shown in FIG.

[0045] The nebulizer includes a main unit 100, a mask 200, an atomizing device 300, and a strap 400. The main unit 100, mask 200, and atomizing device 300 are integrated into a single unit. The strap 400 connects the two ends of the unit and holds it against the user's face. The atomizing device 300 atomizes the liquid medicine and disperses it into the mask 200. The main unit 100 includes a housing 110 and houses the necessary electrical components, which provide power and control signals to the atomizing device 300.

[0046] Figure 1 The orientation of the atomizer shown is consistent with the orientation of the atomizer when worn on the user's face. From a top view, the frame 110 is V-shaped as a whole, and includes a first side wing 111 and a second side wing 112 connected to each other at an obtuse angle (e.g., 115 degrees). The first side wing 111 and the second side wing 112 are both flat rectangular box-shaped. The open side of the V-shaped structure of the frame 110 is used to connect to the mask 200. In this embodiment, the frame 110 is in the form of a shell formed by a thin sheet structure, and the interior of the shell is a chamber in which parts can be installed. The shell has a large width and a small thickness.

[0047] The electrical components are installed inside the second side wing 112 of the frame 110 . The electrical components include a battery 121 and a control device 122 , which are arranged in the width direction of the second side wing 112 .

[0048] The atomizing device 300 can be detachably mounted on the main unit 100. Specifically, in the main unit 100, a recessed portion 116 is provided on the outer surface of the first side wing 111 of the frame 110, and a through-hole 117 is provided at the bottom of the recessed portion 116. The atomizing device 300 is embedded in the recessed portion 116. The atomizing device 300 is flat in shape and is parallel to the first side wing 111 when installed in the recessed portion 116. Most of its structure is located inside the frame 110, and a small part of its structure protrudes from the outer surface of the frame 110. The atomizing device 300 is electrically connected to the electrical components to obtain the power and control signals required for atomizing the liquid medicine. The atomizing device 300 also inputs the medicine mist into the interior of the mask 200 via the through-hole 117 of the frame 110 through the mist outlet pipe 320.

[0049] refer to Figures 4 to 6 , Figure 4 for Figure 1 Axonometric view of the atomizing device in the atomizer shown in, Figure 5 for Figure 4A front view of the atomizing device shown in FIG. Figure 6 for Figure 5 AA cross-sectional view.

[0050] The atomizing device 300 includes a medicine cup 310, an atomizing sheet assembly 320, an atomizing pipe 330, a first magnetic structure 341, a second magnetic structure 342, a probe 350 and a contact 360. The medicine cup 310 is a flat container for containing liquid medicine, and a medicine outlet 315 is provided at the bottom thereof. The atomizing sheet assembly 320 is used to receive the liquid medicine flowing out of the medicine outlet 315. The atomizing pipe 330 is coaxially arranged with the atomizing sheet assembly 320 to limit the discharge path of the medicine mist output by the atomizing sheet assembly 320. The first magnetic structure 341 and the second magnetic structure 342 are used to cooperate with the magnet on the host 110 to keep the atomizing device 300 on the host 110. The probe 330 is located below the medicine outlet 315 and is used to detect the liquid level of the medicine liquid. The contact 360 is used for power transmission and control signal transmission between the atomizing device 300 and the host 100.

[0051] For reference Figures 7 to 9 , which shows the structure of the medicine cup 310. The medicine cup 310 includes a main shell 311, an outer shell 312, a perspective panel 313, a medicine adding port 318, a stopper 317, and a recessed portion 319. The main shell 311 and the perspective panel 313 together enclose a chamber C, and the outer shell 312 is used to maintain the perspective panel 313 and the main shell 311 as a whole. The medicine cup 310 is a flat rectangular box with a width slightly greater than the height and a minimum thickness. The two side surfaces of the medicine cup 310 in the thickness direction are a first surface S1 and a second surface S2. When the medicine cup 310 is installed on the main unit 100, the first surface S1 faces the main unit 100. The recessed portion 319 is provided on the first surface S1.

[0052] The main shell 311 includes a main side plate with rounded corners and a vertical plate surrounding the edge of the main side plate, which together form an open space. The outer surface of the main side plate corresponds to the first surface S1. Figure 9In the orientation shown, the opening of the open space faces the side, and a drug addition port 318 is provided on the top. A bottom plate 314 is provided in the lower half of the open space, and the space between the bottom plate 314 and the vertical plate above it is a chamber C for containing the medicine liquid. The space below the bottom plate 314 can be used to install electrical components. The bottom plate 314 includes a transverse extension section and a vertical extension section. One end of the transverse extension section is connected to a vertical plate located on one side in the width direction of the medicine cup 310 (the left part in the figure), and the other end extends at a small angle to the vertical plate opposite to the aforementioned vertical plate (the right part in the figure). The lower end of the vertical extension section of the bottom plate 314 starts from the other end of the transverse extension section, extends upward at an angle as a whole, and the upper end is connected to the vertical plate (the right part in the figure). This arrangement allows the medicine liquid to flow to the junction of the transverse extension section and the vertical extension section, and the medicine outlet 315 is provided at this junction. Continue to refer to Figure 8 . The recessed portion 319 is recessed from the first surface S1, and its shape is roughly a cylindrical hole. The recessed portion 319 intersects the first surface S1 at an angle, that is, the recessed portion 319 does not extend along the normal direction of the first surface S1, but the extension direction has a small angle (such as 14 degrees) with the normal direction of the first surface S1. A through hole is also provided at the bottom of the recessed portion 319. In the extension direction of the recessed portion 319, the projection of the recessed portion 319 does not fall completely into the chamber C. Only the projection of an area of ​​its upper half falls into the chamber C. The aforementioned through hole is provided in the overlapping area between the bottom of the recessed portion 319 and the chamber C in the aforementioned projection direction. The through hole forms the medicine outlet 315 at the bottom of the chamber C.

[0053] The perspective panel 313 is a plate structure that is roughly in the shape of a rounded rectangle, which can cover the opening of the open space of the main shell 311. The outer shell 312 is snapped onto the main shell 311, and its inner surface surrounds the outer peripheral surface formed by the vertical plate of the main shell 311, and the perspective panel 313 is pressed onto the end surface of the vertical plate of the main shell 311. The perspective panel 313 and the main shell 311 together enclose a chamber C. In other words, both are the walls of the chamber C. In this embodiment, the outer shell 312 is also provided with a window, so that the main body of the perspective panel 313 corresponds to the window. When the perspective panel 313 is made of a transparent material, the user can observe the amount of liquid medicine through the window. The perspective panel 313 is located on the side of the second surface S2 of the medicine cup 310.

[0054] The main shell 311, the outer shell 312 and the perspective panel 313 are assembled together to form the main structure of the medicine cup 310. A chamber C for containing liquid medicine is formed inside the medicine cup 310, and a dosing port 318 for injecting liquid medicine into the chamber C is provided at the top. The dosing port 318 is provided with a pluggable plug 317. The plug 317 includes a plug body 317a and a plug cap 317b. When the plug 317 is plugged into the dosing port 318, the plug body 317a is inserted into the dosing port 318, and the convex edge of the plug cap 317b surrounds and covers the periphery of the dosing port 318. In addition, a ventilation gap G is formed between the plug body 317a and the dosing port 318. The ventilation gap G is used to connect the inside and outside of the chamber C so that external air can enter the chamber C when the atomizer assembly 320 consumes the liquid medicine in the chamber C, thereby avoiding the formation of a negative pressure environment in the chamber C. The plug cap 317b can cover the upper end of the ventilation gap G to prevent the liquid from overflowing, and the ventilation gap G will not be blocked due to the assembly gap and / or the elasticity of the plug cap material, thus taking into account the needs of ventilation and overflow prevention.

[0055] The atomizer sheet assembly 320 is a micro-mesh atomizer sheet, including a circular stainless steel mesh and a piezoelectric sheet. The atomizer sheet assembly 320 is installed at the bottom of the recessed portion 319 of the medicine cup 310. The inner side P1 of the atomizer sheet assembly 320 faces the medicine outlet 315, and the outer side P2 is opposite to the inner side P1 and has the same direction as the first surface S1. There is a sealed connection between the atomizer sheet assembly 320 and the recessed portion 319. After the liquid medicine in the chamber C of the medicine cup 310 flows out from the medicine outlet 315, it will be intercepted and atomized by the atomizer sheet assembly 320, and the formed medicine mist will be sprayed out from the outer side P2. When the user is in use, the atomizer device 300 is in an upright posture (such as Figure 4 As shown in the figure, the axis of the mist outlet pipe 330 is roughly horizontal, and the atomizing sheet assembly 320 is in an upright position.

[0056] The mist outlet pipe 330 is inserted into the recessed portion 319. Specifically, the first end 331 of the mist outlet pipe 330 is located within the recessed portion 319 and is sealed to the outer side P2 of the atomizing plate assembly 320. The second end 332 of the mist outlet pipe 330 protrudes outside the recessed portion 319, that is, the second end 332 is higher than the first surface S1 of the medicine cup 310. In addition, the recessed portion 319 intersects with the first surface S1 of the medicine cup 310 at an angle, so that the mist outlet pipe 330 protrudes obliquely from the first surface S1. Specifically, the medicine cup 310 has a first side 310L and a second side 310R. When the medicine cup 310 is placed on the nebulizer main unit 100, the first side 310L is closer to the center of the nebulizer main unit 100 than the second side 310R, and the distance between the recessed portion 319 and the first side 310L of the medicine cup 310 is less than the distance between the recessed portion 319 and the second side 310R of the medicine cup 310. In this way, although the medicine cup 310 is offset to one side of the host 100, the mist outlet 333 of the mist outlet pipe 330 can basically face the mouth and nose of the user.

[0057] When the recessed portion 319 is tilted, its axial length is greater than its length when perpendicular to the first surface S1. Therefore, the mist outlet pipe 330 is also tilted relative to S1. When the overall thickness of the atomizing device 300 remains unchanged, its overall length is greater than its length when perpendicular to S1. In this way, the medicine mist sprayed from the atomizing sheet assembly 320 will have a relatively longer diffusion distance, which is conducive to the full diffusion of the medicine mist when it reaches the user's mouth and nose. In addition, refer to Figure 3 The recessed portion 319 obliquely intersects the first surface S1, with its top end further away from the first side 310L of the medicine cup 310 than its bottom end. This arrangement also allows the mist outlet 333 to direct mist away from the inner surface 201 of the other side mask 200, thereby reducing condensation of the medicine mist on that surface.

[0058] In addition, a barrier 334 is disposed within the mist outlet pipe 330. Within at least one cross-section of the mist outlet pipe 330, the barrier 334 forms at least one barrier portion 334a at a predetermined distance from the inner wall of the mist outlet pipe 330. The barrier 334 is located outside the spray path of the atomizer assembly 320. In this embodiment, the barrier 334 is an annular flange that protrudes axially from the bottom of the mist outlet pipe 330, located at the first end 331, toward the second end 332. The central channel of the annular flange allows for the spray mist to be discharged. The diameter of the annular flange is smaller than the diameter of the mist outlet pipe 330, and its annular top surface forms the barrier portion 334a. This annular top surface has a diameter smaller than the inner diameter of the mist outlet pipe 330, leaving a predetermined gap from the inner wall of the mist outlet pipe 330. If a user's finger enters the tube lumen from the second end 332 of the mist outlet pipe 330, the barrier portion 334a prevents the fingertip from further insertion, thereby preventing the fingertip from contacting the atomizer assembly 320. The blocking member can also be of other shapes, as long as it can prevent the user's fingers from entering the cavity of the mist outlet pipe 330 and does not prevent the spraying of the medicine mist. For example, the annular flange can also be replaced by an array composed of multiple columns, which is equivalent to forming an annular fence, and the top of the fence is equivalent to the blocking part formed at a certain cross-section of the mist outlet pipe; the number of columns can also be smaller, such as any number from 1 to 4; for example, a rib structure facing the center, or a protrusion of other shapes facing the center is provided on the inner wall of the mist outlet pipe 330, and the portion of the rib or protrusion facing the second end 332 of the mist outlet pipe forms a blocking part.

[0059] The atomizing device 300 is also provided with a contact 360. When the atomizing device 300 is mounted on the housing 110, the contact 360 is electrically connected to the electrical components of the host 100. The contact 360 is located on the first surface S1 of the medicine cup 310. In this embodiment, the contact 360 is a spring pin.

[0060] The atomizing device 300 is also provided with a ferromagnetic structure for forming a magnetic connection with the magnet on the main unit 100, so that the atomizing device 300 is retained in the recess 116 and is easily removed from the recess 116. Specifically, the first surface S1 of the medicine cup 310 is provided with a first magnetic structure 341 and a second magnetic structure 342, which are spaced apart, and the second magnetic structure 342 is adjacent to the contact 360. The provision of two magnetic structures can make the atomizing device 300 more firmly retained on the main unit 100, and the second magnetic structure 342 provided at the contact 360 can also compress the spring pin, making the electrical connection more reliable, and can also prevent the rebound force of the spring pin from reducing the connection strength between the atomizing device 300 and the main unit 100.

[0061] The medicine cup 310 is also provided with handles 316 on its first side 310L and second side 310R, for conveniently removing the atomizer 300 from the main unit 100. In this embodiment, the handles 316 are raised strips protruding from the surface. In some alternative embodiments, the handles 316 may also be grooves. Both raised strips and grooves provide easy fingertip support. The atomizer 300 can be easily removed from the main unit 100, making it easier to add liquid medicine and clean the medicine cup. If the atomizer 300 is damaged, it can be replaced with a new one without having to discard the entire atomizer.

[0062] The mask 200 covers the user's mouth and nose, retaining the atomized liquid mist around the user's mouth and nose. The first end 210 of the mask 200 is designed to contact the user's face, and the second end 220 is designed to connect to the main unit 100. The second end 220 is a mounting surface for connection to the main unit 100.
