Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a medicine cup unit and a nebulizer. Background Technology

[0002] Nebulization therapy, as an effective treatment for respiratory diseases, involves using a nebulizer to disperse medication into tiny droplets or particles, suspending them in a gas stream. These particles then enter the respiratory tract and lungs through the respiratory system, achieving targeted therapy. Due to its unique advantages such as high safety, painlessness, strong local action, few side effects, direct targeting of the lesion, and rapid onset of action, it has been widely used to treat respiratory diseases, respiratory infections, and to eliminate inflammation and edema.

[0003] With the increasing popularity of nebulizer therapy, home nebulizers are also widely used. A typical home nebulizer consists of a main unit and a medicine cup unit. The medicine cup unit includes an atomizing plate for atomizing the medication into an aerosol and a delivery tube for delivering the aerosol to the patient. Considering the portability of the nebulizer, the medicine cup, atomizing plate, and delivery tube are arranged sequentially and tightly connected along the direction of medication and aerosol delivery, forming a single unit collectively referred to as the medicine cup unit. For easy cleaning and disinfection of components such as the medicine cup, the medicine cup unit is detachably connected to the main unit.

[0004] Nebulizers require disinfection after use, with a focus on the medicine cup unit. However, typical household environments and disinfection methods are often unprofessional. For better disinfection, boiling is a more effective method. In existing technology, gaps inevitably exist at the connection between the mist outlet tube and the medicine cup. When boiling is used, water can enter the atomizing plate's housing through these gaps. Because the atomizing plate's housing is a closed structure, water is difficult to expel, leading to atomizing plate malfunctions (abnormal vibration or electrode operation) or even damage rendering it unusable. Even applying an adhesive layer to the connection cannot completely prevent water from entering the atomizing plate's housing. Therefore, existing medicine cup units are unsuitable for boiling disinfection, limiting the atomizing plate's effectiveness and lifespan. Utility Model Content

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] Figure 1 This invention illustrates a nebulizer according to an embodiment of the present invention, specifically comprising a main unit 3 and a medicine cup unit detachably connected to the main unit 3. The top of the main unit 3 is provided with an electrode connection port for connecting to the medicine cup unit, and the bottom plate of the medicine cup unit is provided with an electrode 43 for connecting to the main unit 3. When the medicine cup unit is connected to the main unit 3, the electrode 43 of the medicine cup unit connects to the electrode connection port on the main unit 3, thereby allowing the operation of the nebulizing plate 18 in the medicine cup unit to be controlled by controlling the main unit 3. After nebulization treatment, the main unit 3 can be wiped with disinfectant to disinfect it. However, since the nebulizing plate 18 is located in the internal space, after prolonged or repeated use, a more effective method is to disassemble the medicine cup unit and disinfect it by boiling in water. Therefore, this invention provides a medicine cup unit that effectively avoids the problem of water retention inside the medicine cup unit after boiling disinfection.

[0036] Figure 2 - Figure 5 The present invention illustrates the specific structure of a medicine cup unit according to a specific embodiment. The medicine cup unit includes a medicine cup 1 and a mist delivery tube 2 connected to each other. A receiving chamber is formed at the connection position between the medicine cup 1 and the mist delivery tube 2. A medicine outlet 110 is provided on the side of the receiving chamber near the medicine cup 1, and the medicine outlet 110 communicates with the medicine cup 1. A mist outlet 29 is provided on the side of the receiving chamber near the mist delivery tube 2, and the mist outlet 29 communicates with the mist delivery tube 2. A sealing component and a mist delivery tube 29 are also provided between the atomizing plate 18 and the mist outlet 29. The sealing component is provided between the mist outlet 29 and the atomizing plate 18, and / or the sealing component is provided between the medicine outlet 110 and the atomizing plate 18. An internal space is formed between the outer side of the sealing component and the side wall of the receiving chamber, wherein the outer side of the sealing component is the outer surface of the sealing component in the radial direction. At least one communication port 12 is provided on the side wall of the receiving chamber, and the communication port 12 connects the internal space in the receiving chamber with the outside of the receiving chamber.

[0037] In this embodiment of the invention, the atomizing plate 18 can be disposed on the side of the receiving chamber near the medicine cup 1, that is, the atomizing plate 18 is disposed near the medicine outlet 110. In this case, the sealing assembly is connected between the atomizing plate 18 and the mist outlet 29, so that the radial inner side of the sealing assembly forms a sealed channel between the atomizing plate 18 and the mist outlet 29. Optionally, the atomizing plate 18 can also be disposed on the side of the receiving chamber near the mist outlet 29, that is, the atomizing plate 18 is disposed near the mist outlet 29. In this case, the sealing assembly is connected between the atomizing plate 18 and the medicine outlet 110, so that the radial inner side of the sealing assembly forms a sealed channel between the atomizing plate 18 and the medicine outlet of the medicine cup 1. A sealed channel is provided; optionally, the atomizing plate 18 can also be positioned in the middle of the receiving chamber. In this case, the sealing assembly includes a first sealing assembly 45 and a second sealing assembly 41, with the atomizing plate 18 positioned between the first sealing assembly 45 and the second sealing assembly 41. The first sealing assembly 45 connects the liquid outlet 110 and the atomizing plate 18, and the second sealing assembly 41 connects the atomizing plate 18 and the mist outlet 29. In this case, the radial inner surface of the first sealing assembly 45 forms a sealed channel between the atomizing plate 18 and the liquid outlet 110, and the radial inner surface of the second sealing assembly 41 forms a sealed channel between the atomizing plate 18 and the mist outlet 29. This invention allows for the setting of the connection position of the atomizing plate 18 according to actual needs, ensuring that a sealed channel is formed between the liquid outlet of the medicine cup 1 and the atomizing plate 18, and between the atomizing plate 18 and the mist outlet 29, to prevent leakage of liquid or aerosol.

[0038] In one specific embodiment of this utility model, the atomizing plate 18 is installed in the sealed chamber through a first sealing component 45 and a second sealing component 41. Both the first sealing component 45 and the second sealing component 41 are annular sealing rings. One end of the second sealing component 41 abuts against the outer circumference of the gas side of the atomizing plate 18, and the other end abuts against the outer circumference of the mist outlet 29. Since the sealing ring is elastic, it can flexibly clamp and fix the atomizing plate, forming a sealed channel while protecting the atomizing plate 18. One end of the first sealing component 45 abuts against the outer circumference of the liquid side of the atomizing plate 18, and the other end abuts against the outer circumference of the liquid outlet 110, preventing the liquid from leaking between the liquid outlet 110 and the atomizing plate 18, further playing the role of sealing and protecting the atomizing plate 18.

[0039] Furthermore, in this embodiment of the invention, one end of the second sealing component 41 abuts against the outer circumference of the atomizing plate 18, and the other end abuts against the outer circumference of the mist outlet 29, forming a sealed channel from the atomizing plate 18 to the mist outlet 29. The aerosol generated by the vibration of the atomizing plate 18 can be temporarily encased inside the sealed channel and, as the user inhales, reaches the patient's mouth and nose through the mist delivery tube 2, effectively preventing aerosol overflow and waste. Simultaneously, the first sealing component 45 is provided between the liquid outlet 110 and the atomizing plate 18 to further prevent liquid leakage from the liquid outlet 110 side. Due to the installation requirements of the medicine cup 1 and the mist delivery tube 2, in addition to the atomizing plate 18, a connecting seat is also provided at the connection point for a secure connection between the medicine cup 1 and the mist delivery tube 2. An electrode connecting wire 42 is also required to connect the atomizing plate 18 and the electrode 43. Obviously, the electrode connecting wire 42 should be located outside the sealing component to avoid oxidation due to prolonged contact with the aerosol. Therefore, in existing nebulizers, there is usually an "internal space" between the inner wall of the receiving chamber and the outer side of the sealing assembly (in this specific embodiment, the outer side of the second sealing assembly 41 and the outer side of the first sealing assembly 45). This internal space is used to accommodate components such as the electrode connection wire 42 and the mounting base. However, due to the presence of connection gaps, water can enter this "internal space" through the gaps during boiling disinfection, but it is difficult to completely expel the water from the gaps. The medicine cup unit provided in this embodiment of the present invention has at least one communication port 12 on the side wall of the receiving chamber. This not only allows for effective disinfection of the internal space between the inner wall of the receiving chamber and the outer wall of the sealing assembly during boiling disinfection, avoiding disinfection dead zones, but also allows the water inside to be smoothly expelled through the communication port 12, thereby improving the service life of the medicine cup unit.

[0040] Furthermore, in a specific embodiment of this utility model, the medicine cup 1 includes a medicine cup body and a front shell 11 protruding from the side of the medicine cup body. The front shell 11 includes a bottom surface 13 and a vertical wall 14 protruding from the bottom surface 13. A liquid outlet 110 is provided on the bottom surface 13. The bottom surface 13 and the side wall of the medicine cup 1 are interconnected, and the liquid outlet 110 is connected to the medicine cup 1. In a specific embodiment of this utility model, the medicine cup body and the front shell 11 of the medicine cup 1 are integrally formed. The medicine cup body can be cylindrical or rectangular with rounded corners. The design of the front shell 11 protruding from the medicine cup body not only provides an installation platform for the atomizing plate 18 and the electrode connection line 42, but also allows for a tighter connection with the rear shell 21 of the mist delivery tube 2.

[0041] Furthermore, a rear housing 21 is formed at one end of the mist delivery tube 2 near the medicine cup 1. The rear housing 21 includes a rear housing bottom surface 23 and a rear housing vertical wall 24 protruding from the rear housing bottom surface 23. A mist outlet 29 is provided on the rear housing bottom surface 23. The mist outlet 29 is connected to the mist delivery tube 2. The front housing 11 and the rear housing 21 are connected to each other. The front housing vertical wall 14 and the rear housing vertical wall 24 abut against each other to form a circumferential sidewall of the receiving chamber.

[0042] It should be noted that the sidewall of the receiving chamber can be formed by the front shell vertical wall 14 and the rear shell vertical wall 24 abutting each other as in the aforementioned embodiment; or the rear shell 21 can only include the rear shell bottom surface 23, and the front shell vertical wall 14 abuts with the rear shell bottom surface 23 to form the sidewall of the receiving chamber; similarly, the front shell 11 can only include the front shell bottom surface 13, and the rear shell vertical wall 24 abuts with the front shell bottom surface 13 to form the sidewall of the receiving chamber.

[0043] As shown in the attached figure, the outer diameter of the rear housing 21 is the same as that of the front housing 11, and is significantly larger than that of the mist delivery tube 2 and the atomizing plate 18. This design not only provides space for the mounting base and electrode connection line 42, but also provides a shock-absorbing space for the atomizing plate 18, which protects the internal atomizing plate 18 from direct damage by external forces.

[0044] Furthermore, in a specific embodiment of this utility model, the outer contour of the front housing 11 includes an arc-shaped structure on the upper side and a rectangular structure protruding from the arc-shaped structure on the lower side; the outer contour of the rear housing 21 includes an arc-shaped structure on the upper side and a rectangular structure protruding from the arc-shaped structure on the lower side. Setting the outer wall of the receiving chamber as an arc-shaped structure makes the structural shape smoother, improving the overall aesthetics while preventing stress concentration during impacts or drops, making the device more stable and durable. It should be noted that in this embodiment of the utility model, the lower side is for housing the atomizer... Figure 1 The lower part when placed upright, and the upper part for holding the atomizer. Figure 1 When placed upright, the upper part and the lower part form a whole. Therefore, the outline is specifically a circle and a rectangle whose outer contours are spliced ​​together, with the circle on the upper side and the rectangle on the lower side. In the preferred embodiment of this utility model, the diameter of the upper circle is larger than the side length of the connecting side of the lower rectangle, so that the circular structure has a larger area to accommodate the atomizing plate 18, while the lower rectangle has a smaller area to accommodate the electrode connecting line 42.

[0045] Furthermore, referring to Figure 3 and Figure 4In this embodiment of the present invention, an electrode connecting line 42 is also connected to the atomizing plate 18. In order to fix the electrode connecting line 42 more stably, the electrode connecting line 42 is preferably configured as a sheet structure. The other end of the electrode connecting line 42 is connected to an electrode 43. The electrode 43 passes through the bottom surface of the front housing 11 and reaches the other side of the medicine cup sidewall. When the medicine cup unit is inserted into the host 3, the electrode 43 can be connected to the electrode connection port on the host 3.

[0046] Understandably, in a preferred embodiment of this utility model, the bottom surface of the medicine cup body is located in the middle of the side wall of the medicine cup. This middle position can be closer to the upper side of the medicine cup body or closer to the lower side of the medicine cup body. Since the front shell 11 and the medicine cup 1 are integrally formed in this embodiment of the utility model, the bottom surface 13 of the front shell and the corresponding position of the side wall of the medicine cup can share a side surface. A liquid inlet hole is formed on this side surface. The atomizing plate 18 is located outside the liquid inlet hole, and multiple positioning ribs 17 are also provided around the liquid inlet hole. The multiple positioning ribs 17 are used to abut against the outer edge of the atomizing plate 18 to fix the atomizing plate 18. Meanwhile, a clearance through hole is provided on the side of the lower side of the medicine cup 1 that is opposite to the front housing 11. One end of the electrode 43 is connected to the electrode connection line 42, and the other end passes through the bottom surface 13 of the front housing to reach the inner side of the lower side of the medicine cup 1. When inserting the medicine cup unit, the host 3 enters the bottom of the medicine cup 1 through the clearance through hole, connects to the outer side of the bottom surface of the medicine cup through the buckle at the top of the host 3, and connects to the electrode connection port on the host 3 through the electrode 43.

[0047] The above-mentioned structural design of the medicine cup 1 not only makes the connection between the medicine cup unit and the host 3 more secure, but also allows the center of the atomizing plate 18 to be set on the liquid inlet hole at the bottom of the medicine cup 1, so that the atomizing plate 18 can atomize the medicine liquid in the medicine cup 1 in a comprehensive manner and avoid medicine liquid residue.

[0048] Furthermore, a front housing connecting post 19 is provided on the bottom surface 13 of the front housing, and a rear housing connecting post 28 corresponding to the front housing connecting post 19 is provided on the bottom surface 23 of the rear housing. A fixing screw passes through the outer side of the bottom surface 23 of the rear housing and connects to the rear housing connecting post 28 and the front housing connecting post 19, thereby connecting the front housing 11 and the rear housing 21. In this embodiment, four front housing connecting posts 19 protrude from the bottom surface 13 of the front housing, and four rear housing connecting posts 28 protrude from the bottom surface 23 of the rear housing. Typically, the rear housing connecting post 28 has a smooth inner wall through hole, and the front housing 11 has a threaded countersunk hole. The fixing screw passes through the rear housing connecting post 28 and engages with the threaded hole on the front housing connecting post, thus connecting and fixing the front housing 11 and the rear housing 21. In a preferred embodiment of this invention, the fixing screw is a self-tapping screw, achieving a stable connection between the front housing 11 and the rear housing 21.

[0049] Furthermore, since the electrode connection line 42 is located on the lower side of the receiving chamber, in this embodiment of the present invention, the lower side of the front housing 11 is a rectangular structure protruding from the arc-shaped structure, and the lower side of the rear housing 21 is also a rectangular structure protruding from the arc-shaped structure. This rectangular structure provides a receiving space for the electrode connection line 42, and can also abut against the side wall at the end of the main unit 3 through the rectangular structure of the front housing 11, ensuring a stable connection between the medicine cup unit and the main unit 3.

[0050] Furthermore, in this embodiment of the present invention, the sidewall of the receiving chamber has a straight structure near the bottom of the receiving chamber, and at least one boss assembly is provided at the bottom of the receiving chamber. The boss assembly and the straight structure of the sidewall of the receiving chamber are spaced apart to form a communication port between the boss assembly and the straight structure.

[0051] Specifically, in one embodiment of the present invention, the front housing wall 14 has a straight structure extending vertically near the bottom of the receiving chamber. The bottom of the front housing 11 is provided with at least a first protrusion 16, which is spaced apart from the straight structure of the front housing wall 14. Similarly, the rear housing wall 24 has a straight structure extending vertically near the bottom of the receiving chamber. The bottom of the rear housing 21 is provided with a second protrusion 26 corresponding to each of the first protrusions 16, which is spaced apart from the straight structure of the rear housing wall 24. The second protrusion 26 and the first protrusion 16 abut against each other to form a protrusion assembly, so as to form a communication port 12 between the straight structure of the front housing wall 14 and the rear housing wall 24 and the abutment position of the first protrusion 16 and the second protrusion 26 (i.e., the protrusion assembly). Understandably, in this embodiment of the present invention, the bottom of the front housing 11 and the bottom of the rear housing 21 are the lowest side edges. In this embodiment of the present invention, the front housing wall 14 near the bottom of the receiving chamber has a straight structure, which can be a straight structure perpendicular to the horizontal plane as shown in the figure, or it can be an oblique line with a preset inclination angle. Similarly, the structure of the rear housing wall 24 is similar to that of the front housing wall 14.

[0052] In a specific embodiment of this utility model, since the lower sides of the front housing 11 and the rear housing 21 are rectangular structures, the front housing wall 14 and the rear housing wall 24 are respectively interrupted at the bottom, which is conducive to the residual water in the cavity flowing out from the bottom connecting port 12. At the same time, the water can flow out along the wall, avoiding the residual water at the corner of the bottom of the front housing wall 14 and the rear housing wall 24.

[0053] Furthermore, in a preferred embodiment of the present invention, the first boss 16 can be configured as multiple, preferably two, and the corresponding second boss 26 can also be multiple, preferably two. In this case, the boss assembly formed after the first boss 16 and the second boss 26 abut together is at least two, and a communication port 12 is also formed between the two boss assemblies. The communication hole at the bottom of the receiving chamber is at least three, which can further facilitate the outflow of liquid.

[0054] Furthermore, in a further embodiment of this utility model, a groove extending to the side of the receiving chamber is formed on the side wall of the receiving chamber, so that the groove extending to the side of the receiving chamber forms a communication port 12. The side of the receiving chamber is the end face of the receiving chamber near the medicine cup 1 (i.e., the bottom surface 13 of the front housing), and / or the end face of the receiving chamber near the mist delivery tube 2 (i.e., the bottom surface 23 of the rear housing), which together with the side wall of the receiving chamber form the receiving chamber. The groove extending to the side of the receiving chamber provides a communication port 12 connecting the internal space between the outer side of the sealing assembly and the side wall of the receiving chamber to the outside.

[0055] In a specific embodiment of this utility model, at least one groove extending to the bottom surface 13 of the front housing is provided on the front housing vertical wall 14, and / or at least one groove extending to the bottom surface 23 of the rear housing vertical wall 24 is provided on the rear housing vertical wall 24, so as to form a communication opening 12 when the front housing vertical wall 14 and the rear housing vertical wall 24 abut against each other. The position of the groove can be set according to the actual situation. The groove can be set at the same position, or the groove can be set at different positions on the front housing 11 and the rear housing 21 respectively. In addition, the groove extending to the bottom surface can further facilitate the outflow of internal water and avoid dead corners.

[0056] Furthermore, since the top of the medicine cup 1 is usually provided with a medicine cup lid 44, which can be opened and closed to the top of the medicine cup 1, and since the opening and closing connector or the edge of the medicine cup lid 44 will protrude from the side of the medicine cup 1, in order to facilitate the discharge of water from the top of the chamber, in the preferred embodiment of this utility model, the top of the rear shell 21 is provided with a first groove 27, and a communication opening 12 is formed between the first groove 27 and the front shell vertical wall 14. At this time, the first groove 27 extends to the bottom surface 23 of the rear shell, keeping it at a distance from the side wall of the medicine cup body, avoiding conflict with the opening and closing connector of the medicine cup lid 44 and the edge of the medicine cup 1, which is conducive to accommodating the discharge of water from the chamber. At the same time, since the outer contours of the front shell vertical wall 14 and the rear shell vertical wall 24 at the top are both arc-shaped, water can flow out along the arc-shaped side, which can further avoid dead corners.

[0057] Furthermore, in order to facilitate the outflow of water from the receiving chamber, multiple grooves forming a communication port 12 can be provided on the arc-shaped side wall of the receiving chamber. In order to make the medicine cup unit more robust and durable, grooves should be provided on the front shell vertical wall 14 and / or the rear shell vertical wall 24 respectively. Therefore, in a preferred embodiment of the present invention, a second groove 15 is provided on each side of the front shell 11, and a communication port 12 is formed between the second groove 15 and the rear shell vertical wall 24.

[0058] Furthermore, in a preferred embodiment of the present invention, a stepped structure is provided on the bottom surface 23 of the rear housing, which gradually decreases from the outer periphery of the mist outlet 29 to the outer periphery of the bottom surface 23 of the rear housing. This stepped structure can further promote the outflow of water from the receiving chamber.

[0059] Furthermore, in this embodiment of the invention, at least one vent hole 22 is provided on the side wall of the mist delivery pipe 2. In a preferred embodiment of the invention, four vent holes 22 are provided, located around the mist delivery pipe 2. Due to the presence of the receiving chamber and the sealing device, after the atomizing plate 18 generates aerosol, it will be temporarily contained in the sealed channel between the atomizing plate 18 and the mist outlet 29 formed on the inner side of the second sealing component 41. In a preferred embodiment of the invention, the vent hole 22 is located at one end near the rear housing 21. The vent hole 22 connects the inner side of the mist delivery pipe 2 with the external space, thereby allowing the air pressure inside the mist delivery pipe 2 to communicate with the outside. When spraying, the closer the vent hole 22 is to the atomizing plate 18, the less the airflow vortex inside the mist delivery pipe 2 will be, which is more conducive to the aerosol being delivered to the outside along the mist delivery pipe 2. At the same time, the four vent holes 22 can make the air intake uniform, and prevent the aerosol from forming vortices in the mist delivery pipe 2 when it is transmitted to the user along the mist delivery pipe 2, which would lead to deposition.

[0060] Furthermore, a snap-fit ​​rib 25 is provided along the axial direction of the mist delivery pipe 2, protruding from the side wall of the mist delivery pipe 2 and gradually rising towards the rear housing 21. A preferred embodiment of the snap-fit ​​rib 25 is a stepped structure as shown in the attached figure, which can accommodate mouthpieces or masks of different diameters. Understandably, the snap-fit ​​rib 25 can also be a sloping structure that gradually rises towards the rear housing 21, similarly accommodating mouthpieces or masks of different diameters. In a preferred embodiment of this invention, four snap-fit ​​ribs 25 are provided.

[0061] In one specific embodiment of this utility model, the atomizing tube 2 has an outer diameter close to 20mm, allowing it to be inserted and fitted with ordinary mouthpieces (or atomizing mouthpieces) and face masks. The mounting holes of the mouthpieces or mouthpieces generally fit into the smooth end of the atomizing tube 2. However, some mouthpieces or face masks have tolerances; the locking rib 25 can accommodate these tolerances. Larger diameter tubes can be inserted into the smaller surface of the locking rib 25, with the larger rib acting as a stop. Specifically, this design is compatible with both φ20 and φ22 face masks, as well as φ22 mouthpieces, thus expanding the atomizer's applicability.

[0062] Furthermore, in the initial design phase, to avoid residual moisture in the internal space formed by the outer surface of the sealing component and the sidewall of the receiving chamber, a technical solution was proposed to make the front and rear shells 21 integrally molded, with the atomizing plate 18 embedded in the receiving chamber before molding. The disadvantage of this method is that the atomizing plate 18 cannot be cleaned. Because the atomizing plate 18 generally forms deposits after atomizing the medication, as the deposits increase, the atomization efficiency and parameters of the atomizing plate 18 decrease, failing to meet the requirements for drug atomization and treatment. Alternatively, a special process could be used to increase the connection pressure between the front shell 11 and the rear shell 21 to a waterproof level, preventing water from entering during boiling. However, the disadvantage of this method is that because the atomizing plate 18 needs to vibrate to generate aerosol, excessive connection pressure between the front shell 11 and the rear shell 21 reduces the atomizing plate 18's degrees of freedom, requiring very high power to achieve the same atomization rate, similar to pulling a cart in a 100-meter sprint, which also reduces atomization efficiency. Therefore, while retaining the screw connection between the front housing 11 and the rear housing 21, this utility model provides a connecting port 12 on the side wall of the receiving chamber, which can take into account both the function of the atomizing plate 18 and the cleanliness, while avoiding the problem that water is not easy to shake out.

[0063] This utility model embodiment provides a medicine cup unit with the following advantages:

[0064] 1. The medicine cup unit is provided with at least one communication port 12 on the side wall of the receiving chamber. This not only allows for effective disinfection of the internal space between the side wall of the receiving chamber and the outer surface of the sealing component during the boiling disinfection process, avoiding disinfection dead corners, but also allows the water in the internal space to be smoothly ejected through the communication port 12, thereby improving the service life of the medicine cup unit.

[0065] 2. The bottom of the receiving chamber is connected by a first protrusion 16 and a second protrusion 26 to form a communication port 12 at the bottom, which can accommodate the spatial structure of the receiving chamber and facilitate the flow of water along the front shell vertical wall 14 and the rear shell vertical wall 24 at the bottom, avoiding dead corners.

[0066] 3. The upper side of the accommodating chamber has an arc-shaped structure, and grooves extending to the bottom surface are provided on the front shell vertical wall 14 and / or the rear shell vertical wall 24, which facilitates the flow of water along the bottom surface and the side walls of the vertical wall, avoiding dead corners.

[0067] 4. A snap-fit ​​rib 25 is also provided along the axial direction of the mist delivery tube 2, which can be adapted to mouthpieces and masks of different diameters, thereby improving the applicability of the atomizer.

[0068] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention.
