Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a suction nozzle structure, assembly method, and atomizing device. Background Technology

[0002] Nebulizers for pulmonary inhalation primarily work by atomizing liquid preparations such as medications, nutrients, or nicotine into tiny particles that can be inhaled, thus achieving painless, rapid, and effective treatment. The mouthpiece, as one of the most important components of the nebulizer, is installed at the front end and comes into contact with the mouth to deliver the medication.

[0003] Chinese Patent Publication No. CN 113679910 A discloses a suction nozzle structure, which mainly consists of a hollow shell 101, a flow guiding member 112, and a nozzle assembly (including an atomizing nozzle 103, a nozzle protection member 131, a nozzle clamping member 132, a nozzle fastening member 133, etc.). Among these components, the hollow shell has a concentric cavity seat, and the inner wall of the cavity seat is provided with a step for stopping. The nozzle assembly is installed on top of the flow guiding member, and the flow guiding member has an edge in the middle that matches the step. During assembly, the nozzle assembly is inserted from the bottom of the hollow shell along with the flow guiding member until the edge of the flow guiding member abuts against the step of the cavity seat, thus completing the assembly.

[0004] With the development of miniaturization technology for atomizing devices, this nozzle structure has become less suitable for practical applications, mainly in the following ways:

[0005] 1. After the device is miniaturized, the inner wall of the corresponding cavity will also become thinner, which is not conducive to the processing of the step for the stop. If the step stop is still used, it will easily affect the structural strength of the cavity.

[0006] 2. Due to the relatively long depth of the hollow shell itself, the assembly difficulty increases when inserting the flow guiding component from the bottom of the hollow shell after the volume is reduced.

[0007] Therefore, this application proposes a novel nozzle structure, assembly method, and atomizing device to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a nozzle structure, assembly method, and atomizing device. By modifying the structure of each component, the ease of assembly is improved, and the requirements for miniaturized product production are met.

[0009] The objective of this invention is achieved through the following technical solution:

[0010] A suction nozzle structure, comprising:

[0011] The upper housing has a through cavity inside it;

[0012] An atomizing module, the atomizing module including a flow guiding member, the flow guiding member being inserted downward from above the upper housing into the through cavity, the flow guiding member being provided with a ring edge that abuts against the through cavity;

[0013] The nozzle housing is fitted onto the top of the atomizing module, and the nozzle housing and the upper housing are connected separately by a snap-fit ​​mechanism.

[0014] The above-described solution assembles the flow guiding components from top to bottom, avoiding the inconvenience of bottom-up assembly after component miniaturization, and eliminating the need for a stepped design in the cavity, thus avoiding any impact on the cavity's strength. Furthermore, this application features a separate design for the upper shell and the nozzle shell, facilitating the installation of the flow guiding components and improving the ease of assembly of the nozzle structure.

[0015] In some embodiments, the flow guide member has a plurality of fixed fins evenly distributed around its circumference, and the fixed fins interfere with the through cavity to fix the atomizing module inside the upper housing.

[0016] In the above scheme, the fixed wing design can form line interference with the inner wall of the cavity, reducing assembly resistance and facilitating disassembly or installation.

[0017] In some embodiments, a guide groove is provided on the inner wall of the cavity, and the length direction of the guide groove is consistent with the length direction of the cavity;

[0018] The flow guiding component is provided with a slider that protrudes radially outward. The slider slides in conjunction with the guide groove to restrict the circumferential degree of freedom of the flow guiding component.

[0019] The above solution uses a slider and a guide groove to guide the assembly of the flow guiding components and prevent the atomizing module from rotating circumferentially, thus ensuring the positioning accuracy and reliability of the atomizing module.

[0020] In some embodiments, the atomizing module further includes an atomizing unit and a sealing unit;

[0021] The atomizing unit is disposed on the top of the flow guiding member, and the atomizing unit is used to release atomized drug droplets;

[0022] The sealing unit is disposed at the bottom of the flow guiding member, and the sealing unit is used to seal the infusion tube that extends into the flow guiding member.

[0023] In some embodiments, the through cavity portion protrudes from the upper housing to form a mating end, and a groove is provided on the outer periphery of the mating end;

[0024] A protruding buckle is provided on the inner side of one end of the nozzle housing near the upper housing. The protruding buckle cooperates with the groove to lock the nozzle housing to the upper housing.

[0025] The above solution uses the interplay of protrusions and grooves to achieve rapid assembly of the nozzle shell and the upper shell, offering advantages such as simple connection structure and convenient operation.

[0026] In some embodiments, at least one slot is provided on the outer periphery of the mating end, and the length direction of the slot is consistent with the length direction of the mating end;

[0027] The inner wall of the nozzle housing is provided with a rib plate corresponding to the slot. The rib plate is inserted into the slot to restrict the circumferential degree of freedom of the nozzle housing.

[0028] The above solution uses ribs and slots to guide the assembly of the nozzle housing and prevent the nozzle housing from rotating circumferentially, thus ensuring the positional accuracy and reliability of the nozzle housing.

[0029] In some embodiments, the nozzle housing is provided with air holes, through which air drawn in can mix with drug droplets released by the atomizing unit to form a soft mist.

[0030] The above solution incorporates vents, allowing air drawn in through the vents to come into contact with the drug droplets released by the atomization unit. Under the Rayleigh rupture mechanism, the drug droplets are further broken up and mixed with the air to form a soft mist, thereby improving the atomization effect.

[0031] In some embodiments, a plurality of ventilation grooves are provided on the inner wall of the nozzle housing, and the ventilation grooves are spaced around the outer periphery of the atomizing unit.

[0032] The above solution, by setting up ventilation slots, can ensure that the air drawn in from the air vents can flow smoothly to the nozzle of the atomizing unit, avoiding airflow obstruction caused by the assembly of the atomizing unit and / or nozzle housing due to tolerance reasons.

[0033] In some embodiments, a button is provided on the side wall of the upper housing, the button being used to control the opening and closing of the atomizing module;

[0034] A suction nozzle cover is provided on the upper part of the upper housing, and a button cover extending downward is provided on the side wall of the suction nozzle cover.

[0035] In its initial state, the nozzle cover is detachably fitted onto the top of the atomizing module, while the button cover covers the surface of the button.

[0036] The above solution protects the atomizing module by adding a nozzle cover, preventing impurities from entering and causing blockages or contamination. Covering the button with a cap prevents accidental activation, avoiding waste or contamination of the medication.

[0037] A method for assembling a suction nozzle structure includes the following steps:

[0038] S1. Provides an upper housing, an atomizing module, and a nozzle housing, wherein the upper housing has a through cavity, the atomizing module includes a flow guiding member, and the outer periphery of the flow guiding member is provided with a ring edge;

[0039] S2. Insert the flow guiding member into the cavity from above the upper housing until the ring edge rests against the cavity, thereby fixing the atomizing module inside the upper housing.

[0040] S3. Fit the nozzle housing onto the top of the atomizing module and snap the bottom of the nozzle housing onto the upper housing to complete the assembly of the nozzle structure.

[0041] The above solution assembles the flow guiding components from top to bottom, avoiding the inconvenience of bottom-up assembly after component miniaturization, improving the ease of nozzle structure assembly, and well meeting the needs of product miniaturization production.

[0042] In some embodiments, a guide groove is provided on the inner wall of the cavity, and a portion of the cavity protrudes from the upper housing to form a mating end. A slot is also provided on the outer periphery of the mating end. The length direction of the guide groove and the length direction of the slot are both consistent with the length direction of the cavity.

[0043] The outer periphery of the flow guiding member is also provided with a slider, which is located below the ring edge and slides in cooperation with the guide groove;

[0044] The inner wall of the nozzle housing is provided with ribs, which are inserted into the slot.

[0045] The above solution ensures that the upper shell, atomizing module, and nozzle shell are in the same position, improving the stability and positional accuracy after assembly and ensuring that the performance of the nozzle structure is not affected.

[0046] An atomizing device includes the above-described nozzle structure.

[0047] Compared with the prior art, the beneficial effects of the present invention include at least the following: by optimizing and modifying the components of the atomizing module, the requirements for miniaturized production of the product are met, while the convenience of assembly operations is improved.

[0054] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0055] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0056] See Figures 1 to 5 As shown, the present invention discloses a suction nozzle structure, including an upper shell 1, an atomizing module 2, and a suction nozzle outer shell 3.

[0057] See Figure 1 and Figure 3 As shown, the upper shell 1 is roughly cylindrical in shape, and its interior is provided with a cavity 11 for installing the atomizing module 2.

[0058] For example, the through cavity 11 is arranged coaxially with the upper housing 1, and the two can be integrally molded by injection molding. The through cavity 11 extends downward from the top of the upper housing 1, and its length is about half the length of the upper housing 1.

[0059] See Figure 1 , Figure 2 and Figure 4 As shown, the atomizing module 2 is disposed within the cavity 11 of the upper housing 1. The atomizing module 2 can release a soft mist of medication for the user to inhale for treatment. Specifically, the atomizing module 2 can be installed within the cavity 11 via its own flow guiding component 21.

[0060] For example, the flow guiding member 21 is a tubular component with an internal infusion channel for conveying liquid medications (see...). Figure 1 The flow guide component 21 is adapted to the cavity 11 in shape. During installation, the flow guide component 21 is inserted into the cavity 11 from above the upper housing 1. Through the interference fit between the flow guide component 21 and the inner wall of the cavity 11, the atomizing module 2 can be installed quickly.

[0061] In addition, the flow guide member 21 is provided with a ring edge 211 that abuts against the cavity 11. The ring edge 211 is located approximately on the top outer periphery of the flow guide member 21, and its outer diameter is larger than the inner wall of the cavity 11, so as to ensure that the ring edge 211 can completely abut against the upper end face of the cavity 11, thereby limiting the insertion depth of the atomizing module 2 and also serving as a fall prevention function, thus improving the reliability of the atomizing module 2 after assembly.

[0062] See Figure 1 , Figure 2 and Figure 5 As shown, the nozzle housing 3 is roughly trumpet-shaped and is fitted on top of the atomizing module 2 to protect the atomizing module 2. The nozzle housing 3 and the upper housing 1 are connected separately by a snap-fit, which makes it easy to operate when the flow guide component 21 is installed into the cavity 11 without being obstructed by the nozzle housing 3.

[0063] Compared to existing technologies, the nozzle structure of this application has made significant changes in its assembly method. During assembly, the flow guiding component 21 is assembled from top to bottom, avoiding the inconvenience of bottom-up assembly after component miniaturization. Furthermore, it eliminates the need for a stepped design on the cavity 11, thus preventing any impact on its strength. In addition, this application features a separate design for the upper shell 1 and the nozzle outer shell 3, facilitating the installation of the flow guiding component 21 and improving the ease of assembly, effectively meeting the needs of miniaturized product manufacturing.

[0064] See Figure 2 and Figure 4 As shown, in a preferred embodiment, the flow guide member 21 has a plurality of fixed fins 212 evenly distributed around its circumference. The fixed fins 212 interfere with the cavity portion 11 and form multiple lines of interference, so that the atomizing module 2 is fixed inside the upper housing 1.

[0065] For example, there are four fixed wings 212, which are evenly distributed around the outer periphery of the flow guide member 21. Each fixed wing 212 has an interference surface that can contact the cavity 11, thereby changing the conventional surface interference into four line interference, reducing assembly resistance, and effectively ensuring the stability of the flow guide member 21 under force after installation.

[0066] Furthermore, such as Figures 2 to 5 As shown, a guide groove 111 is provided on the inner wall of the cavity 11, and the length direction of the guide groove 111 is consistent with the length direction of the cavity 11. Correspondingly, the flow guiding member 21 is provided with a slider 213 that protrudes radially outward. The slider 213 slides with the guide groove 111 to restrict the circumferential degree of freedom of the flow guiding member 21, thereby preventing the atomizing module 2 from rotating and ensuring the positional accuracy and reliability of the atomizing module 2.

[0067] Furthermore, the opening of the guide groove 111 is flared to guide the slider 213 into the guide groove 111, thereby improving the smoothness of the atomizing module 2 being installed into the cavity 11.

[0068] See Figure 1 and Figure 2 As shown, in one specific embodiment, the atomizing module 2 further includes an atomizing unit 22 and a sealing unit 23.

[0069] The atomizing unit 22 is located on top of the flow guiding member 21 and is used to release atomized drug droplets. Specifically, the atomizing unit 22 includes an atomizing chip and protective components, clamping components, etc. (not labeled) surrounding the atomizer. The liquid drug output from the infusion channel inside the flow guiding member 21 can be converted into atomized drug droplets and sprayed out under the action of the atomizing chip.

[0070] A sealing unit 23 is disposed at the bottom of the flow guiding member 21. The sealing unit 23 is used to seal the infusion tube (not shown) that extends into the flow guiding member 21. Specifically, the sealing unit 23 includes a sealing ring and a clamping member disposed below the sealing ring, etc. The infusion tube extending into the flow guiding member 21 (i.e., the infusion channel) can form a dynamic seal with the sealing ring.

[0071] See Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, the cavity portion 11 protrudes from the upper housing 1 to form a mating end 112, and a groove 113 is provided on the outer periphery of the mating end 112; correspondingly, a protruding buckle 31 is provided on the inner side of the end of the suction nozzle housing 3 near the upper housing 1, and the protruding buckle 31 and the groove 113 cooperate with each other to make the suction nozzle housing 3 and the upper housing 1 snap-fit ​​and fix.

[0072] Furthermore, such as Figure 2 and Figure 5As shown, at least one slot 114 is provided on the outer periphery of the docking end 112, and the length direction of the slot 114 is consistent with the length direction of the docking end 112. Correspondingly, a rib 32 corresponding to the slot 114 is provided on the inner wall of the nozzle housing 3. The rib 32 is inserted into the slot 114 to restrict the circumferential degree of freedom of the nozzle housing 3, thereby preventing the nozzle housing 3 from rotating and ensuring the positional accuracy and reliability of the nozzle housing 3.

[0073] See Figure 1 and Figure 2 As shown, in one specific embodiment, the nozzle housing 3 is provided with air holes 33. For example, there are two air holes 33 and they are symmetrically distributed on both sides of the nozzle housing 3. The air drawn in through the air holes 33 can come into contact with the drug droplets released by the atomizing unit 22, further breaking the drug droplets under the Rayleigh rupture mechanism, and mixing with them to form a soft mist, thereby improving the atomization effect.

[0074] See Figure 1 and Figure 5 As shown, in a preferred embodiment, a plurality of ventilation grooves 34 are provided on the inner wall of the nozzle housing 3. The ventilation grooves 34 are spaced around the outer periphery of the atomizing unit 22 to ensure that the air drawn in from the air hole 33 can flow to the nozzle of the atomizing unit 22, thereby avoiding airflow obstruction caused by the assembly of the atomizing unit 22 and / or the nozzle housing 3 due to tolerance reasons.

[0075] See Figure 2 As shown, in one specific embodiment, a button 4 is provided on the side wall of the upper housing 1, which is used to control the opening and closing of the atomizing module 2; in addition, a mouthpiece cover 5 is provided on the top of the upper housing 1, and a downwardly extending button cover 51 is provided on the side wall of the mouthpiece cover 5.

[0076] In the initial state, the nozzle cover 5 is detachably fitted on the top of the atomizing module 2 to protect the atomizing module 2 and prevent impurities from entering and causing blockage or contamination; at the same time, the button cover 51 covers the surface of the button 4, which can play a role in preventing accidental touch and avoid waste or contamination of the medicine.

[0077] See Figures 1 to 5 As shown, the present invention also discloses an assembly method for a suction nozzle structure, including steps S1 to S3.

[0078] S1. Provides an upper housing 1, an atomizing module 2, and a nozzle housing 3.

[0079] Among them, such as Figure 1 and Figure 3 As shown, a cavity 11 is provided inside the upper housing 1, and the cavity 11 is located in the center of the upper housing 1 for installing the atomizing module 2.

[0080] like Figure 4As shown, the atomizing module 2 includes a flow guiding component 21, which is a tubular component used to transport liquid medicine. The outer periphery of the flow guiding component 21 is provided with a ring edge 211, which can be located at the top of the flow guiding component 2, and its outer diameter is larger than the inner wall of the cavity 11.

[0081] like Figure 1 and Figure 5 As shown, a protrusion 31 is provided on the bottom inner side of the nozzle housing 3. The protrusion 31 can cooperate with the groove 113 on the outer periphery of the mating end 112 formed on the upper housing 1. An air hole 33 is also provided above the protrusion 31.

[0082] S2. Insert the flow guide member 21 into the cavity 11 from above the upper housing 1 until the ring edge 211 rests against the cavity 11. The outer periphery of the flow guide member 21 can be fixed to the inner wall of the cavity 11 by line interference or surface interference, so that the atomizing module 2 is fixed in the upper housing 1.

[0083] S3. Fit the nozzle housing 3 onto the top of the atomizing module 2, ensuring a certain gap exists between the nozzle housing 3 and the atomizing module 2, which must be sufficient for airflow. Furthermore, snap the bottom of the nozzle housing 3 onto the upper housing 1, using the engagement of the protrusion 31 and the groove 113 to fix the nozzle housing 3 onto the upper housing 1, thus completing the assembly of the nozzle structure of this application.

[0084] The above assembly method avoids the inconvenience of bottom-up assembly after the components are miniaturized by assembling the flow guide 21 from top to bottom (after the components are miniaturized, it is difficult to align the flow guide 21 with the cavity 11 when it is inserted from the bottom of the upper shell 1, which can easily cause collisions and visual obstruction). Furthermore, it does not require a step design for the cavity 11, thus avoiding any impact on the strength of the cavity 11.

[0085] In addition, this application adopts a separate design for the upper shell 1 and the nozzle shell 3, which facilitates the installation of the flow guiding component 21, improves the convenience of nozzle structure assembly operation, and can well meet the needs of product miniaturization production.

[0086] Furthermore, a guide groove 111 is provided on the inner wall of the cavity 11, and a portion of the cavity 11 protrudes from the upper housing 1 to form a mating end 112. A slot 114 is also provided on the outer periphery of the mating end 112. The length directions of the guide groove 111 and the slot 114 are both consistent with the length direction of the cavity 11. A slider 213 is also provided on the outer periphery of the flow guide member 2. The slider 213 is located below the ring edge 211, and the slider 213 slides in engagement with the guide groove 111. A rib 32 is provided on the inner wall of the nozzle housing 3, and the rib 32 is inserted into the slot 114.

[0087] By cooperating with the slider 213 and the guide groove 111, and with the rib 32 and the slot 114, the positions of the upper housing 1, the atomizing module 2 and the nozzle housing 3 can be kept consistent, improving the stability and positional accuracy after assembly and ensuring that the performance of the nozzle structure is not affected.

[0088] This invention also discloses a nebulizer, which can be a metered-dose inhaler (MDI), a soft mist inhaler (SMI), etc., used to deliver medication to the nose, lungs, or other areas for nebulization therapy. This nebulizer includes the aforementioned mouthpiece structure and has advantages such as small size and easy assembly.

[0089] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
