Description

Technical Field

[0001] This invention relates to the field of medical nebulizer technology, specifically a self-cleaning, clog-resistant mesh nebulizer. Background Technology

[0002] Mesh nebulizers use a core filtration system (a filter plate inside the main unit) to filter the medication before delivering it to the core nebulizing mesh for atomization. In medical engineering applications, these devices are commonly used for patients with respiratory diseases requiring long-term, periodic inhalation therapy (such as asthma and chronic obstructive pulmonary disease), placing extremely high demands on the device's long-term operational reliability, dosage accuracy, and safety.

[0003] In long-term use, the filter plates of existing mesh atomizers are prone to clogging due to drug residue, microbial growth, or crystal deposition. Most existing devices rely solely on natural liquid flow for rinsing or require manual disassembly for cleaning. This cleaning method is not only inefficient but also prone to introducing contamination or damaging precision components during disassembly and cleaning, affecting atomization efficiency and the stability of atomization volume, and even leading to atomization failure.

[0004] Therefore, a self-cleaning, clog-resistant mesh atomizer is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a self-cleaning, clog-resistant mesh atomizer.

[0006] The objective of this invention is achieved through the following technical solution: a self-cleaning, anti-clogging mesh atomizer, comprising a main unit with a filter plate installed internally, the spray port of the main unit connected to an inhalation hood, a movable plate, and a telescopic component fixedly connected to the main unit. The telescopic end of the telescopic component is rotatably connected to a rod, which engages with the movable plate via an elastic element. A cleaning plate is located on the top surface of the filter plate, with a sliding groove on the cleaning plate. A push plate that engages with the top surface of the filter plate is slidably fitted within the sliding groove. A rotating plate is hinged to the inner cavity of the main unit. A rotating rod has its top end threadedly connected to the rotating plate via a threaded component, and its bottom end rotatably connected to the cleaning plate. Through the reciprocating movement of the telescopic component, the cleaning plate and the push plate perform circular motion, with the push plate moving along the cleaning plate to complete cleaning. When the telescopic component continues to retract, the cleaning plate and the rotating plate tilt away from the filter plate, completing the retraction. This achieves all-around self-cleaning of the filter plate and automatic retraction of the mechanism after cleaning, significantly improving the self-maintenance capability of the equipment and avoiding the inconvenience and pollution risks of manual disassembly and cleaning.

[0007] As a further description of the above technical solution: The inner cavity of the main unit is fixedly connected to a sealing plate, the rotating plate is hinged to the sealing plate, and the telescopic end of the telescopic component passes through the sealing plate; this enhances the sealing performance of the atomizer's inner cavity, effectively prevents the liquid from overflowing from the moving part of the telescopic rod, and protects the telescopic component from liquid corrosion.

[0008] As a further description of the above technical solution: The telescopic end of the telescopic component is fixedly connected to a U-shaped plate, and the insertion rod has a T-shaped structure. The insertion rod is rotatably connected to the U-shaped plate, ensuring that the linear reciprocating motion of the telescopic component can be flexibly transmitted to the movable plate.

[0009] As a further description of the above technical solution: The elastic element includes multiple first pressure balls arranged in a circle and fixedly connected to the movable plate. A fixed plate is fixedly connected to the bottom of the insertion rod. Multiple second pressure balls that press against and cooperate with the first pressure balls are fixedly connected to the fixed plate. Multiple springs are hung between the fixed plate and the movable plate. When the movable plate and the insertion rod undergo relative angular displacement, a high-frequency, small-amplitude vertical shaking is generated, and this vibration is transmitted to the push plate, which enhances the cleaning effect of removing stubborn deposits.

[0010] As a further description of the above technical solution: A connecting rod passing through a sliding groove is fixedly connected to the push plate, and the connecting rod is fixedly connected to the movable plate; this allows the push plate to slide relative to the cleaning plate while moving synchronously with it, thus expanding the trajectory coverage of a single cleaning and ensuring the thoroughness of the cleaning.

[0011] As a further description of the above technical solution: The rotating rod has a U-shaped structure in the middle, and the end of the movable plate is pressed against the rotating rod; on the one hand, it serves as the fulcrum for the cleaning plate to perform circular motion, and on the other hand, it facilitates the cleaning plate to be tilted and stored with the whole mechanism.

[0012] As a further description of the above technical solution: The movable plate and the cleaning plate are distributed in parallel. Arc-shaped plates are fixedly connected to both sides of the movable plate, and the arc-shaped plates are in abutting fit with the rotating rod. By utilizing the characteristics of the parallelogram mechanism, it is ensured that the movement trajectory of the movable plate and the cleaning plate is stable and consistent when tilted for storage, which helps the mechanism to be compactly and reliably stored in the inner cavity sidewall.

[0013] As a further description of the above technical solution: A mating plate is fixedly connected to the rotating rod, and the mating plate abuts against the arc-shaped plate; the abutting fit forces the rotating rod to overcome the thread resistance and rotate, thereby switching the tilt direction of the mechanism so as to clean the other half of the filter plate later.

[0014] As a further description of the above technical solution: A stirring plate is rotatably connected to the middle of the rotating rod; when the cleaning mechanism is retracted, the stirring plate can rotate with the flow of the liquid medicine, which plays a role in stirring and promoting the uniform mixing of the liquid medicine, thereby indirectly ensuring the uniform concentration of the atomized liquid medicine.

[0015] As a further description of the above technical solution: The sliding groove is composed of a first sliding groove and a second sliding groove connected together. The first sliding groove runs through the middle of the cleaning plate, and the second sliding groove is opened at the bottom of the end of the cleaning plate. The push plate is composed of a first sliding plate located in the first sliding groove and a second sliding plate located in the second sliding groove. The width of the first sliding plate is smaller than the width of the first sliding groove.

[0016] Compared with the prior art, the advantages of the present invention are as follows: This application features a movable cleaning plate and a push plate above the filter plate. A telescopic component drives the cleaning plate and push plate in a reciprocating circular motion, with the push plate pushing linearly relative to the cleaning plate. This allows for continuous scraping and vibration cleaning of the filter plate surface (the elastic component facilitates vibration). Thorough cleaning can be achieved without manual disassembly. After cleaning, the cleaning mechanism retracts further and tilts to store away from the filter plate area, preventing interference with normal liquid flow. This ensures smooth liquid flow and reduces the impact of the cleaning mechanism on the overall operation of the equipment. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-11 The diagram shows an embodiment of a self-cleaning, anti-clogging mesh atomizer provided by the present invention. It includes a main unit 1 with a filter plate 2 installed inside, a spray port of the main unit 1 connected to an inhalation hood 3, a movable plate 4 and a telescopic member 5 (preferably an electric telescopic rod) fixedly connected to the main unit 1. The telescopic end of the telescopic member 5 is rotatably connected to a plug rod 6, and the plug rod 6 is in a wobbling cooperation with the movable plate 4 through an elastic member. The main unit 1 includes a control section, core atomizing components (piezoelectric ceramic, atomizing nozzle, amplitude transformer) and an inner cavity for containing the liquid medicine. It is the core of the atomization function and the main unit 1 uses conventional technology.

[0020] A cleaning plate 7 is located on the top surface of the filter plate 2. A sliding groove 8 is provided on the cleaning plate 7. A push plate 9 that is in slidable and cooperates with the top surface of the filter plate 2 is located in the sliding groove 8. A rotating plate 10 is hinged to the inner cavity of the main unit 1. Rotating rod 11, the top end of rotating rod 11 is threadedly connected to rotating plate 10 through threaded parts, and the bottom end of rotating rod 11 is rotatably connected to cleaning plate 7; The reciprocating motion of the telescopic component 5 causes the cleaning plate 7 and the push plate 9 to move in a circular motion, and the push plate 9 moves along the cleaning plate 7 to complete the cleaning. When the telescopic component 5 continues to retract, the cleaning plate 7 and the rotating plate 10 tilt away from the filter plate 2, completing the storage.

[0021] The inner cavity of the main unit 1 is fixedly connected to a sealing plate 12, the rotating plate 10 is hinged to the sealing plate 12, and the telescopic end of the telescopic component 5 passes through the sealing plate 12 to ensure sealing, prevent the medicine from overflowing, and avoid affecting the telescopic component 5.

[0022] It is worth noting that: the telescopic end of the telescopic component 5 is fixedly connected to a U-shaped plate 13, and the insertion rod 6 has a T-shaped structure. The insertion rod 6 is rotatably connected to the U-shaped plate 13 to ensure the connection between the telescopic end of the telescopic component 5 and the movable plate 4, without affecting the telescopic end of the telescopic component 5 to drive the movable plate 4 to move (drive the movement distance, and ensure relative rotation in the horizontal and vertical directions).

[0023] The elastic element in this application includes multiple first pressing balls 14 arranged in a circle and fixedly connected to the movable plate 4. A fixed plate 15 is fixedly connected to the bottom of the insertion rod 6. Multiple second pressing balls 16 that press against and cooperate with the first pressing balls 14 are fixedly connected to the fixed plate 15. Multiple springs 17 are connected between the fixed plate 15 and the movable plate 4 to ensure that the movable plate 4 rotates horizontally relative to the insertion rod 6 while making a vertical up-and-down sway (slight small distance sway).

[0024] Among them, a connecting rod 18 passing through the sliding groove 8 is fixedly connected to the push plate 9. The connecting rod 18 is connected and fixed to the movable plate 4, so that the push plate 9 and the cleaning plate 7 rotate synchronously, while ensuring that the push plate 9 reciprocates relative to the cleaning plate 7, increasing the cleaning area and ensuring the thoroughness of cleaning.

[0025] Furthermore, the middle part of the rotating rod 11 has a U-shaped structure, and the end of the movable plate 4 is in abutting fit with the rotating rod 11. On the one hand, this ensures that the cleaning plate 7 rotates with the rotating rod 11 as the rotation center, and on the other hand, it facilitates the cleaning plate 7 to be carried away with the rotating plate 10 to complete the storage.

[0026] Among them, the movable board 4 and the cleaning board 7 are distributed in parallel. The parallelogram shape helps the cleaning board 7 and the movable board 4 to be tilted and stored synchronously.

[0027] Arc-shaped plates 20 are fixedly connected to both sides of the movable plate 4. The arc-shaped plates 20 are in abutting fit with the rotating rod 11. A mating plate 21 is fixedly connected to the rotating rod 11. The mating plate 21 is in abutting fit with the arc-shaped plates 20, which further ensures the rotation angle of the rotating rod 11 and ensures the switching position.

[0028] The rotating rod 11 is rotatably connected to a stirring plate 19 in the middle. When the contents are stored, the stirring plate 19 rotates with the flow of the liquid medicine, which helps the liquid medicine to flow and mix.

[0029] The sliding groove 8 in this application is composed of a first sliding groove and a second sliding groove connected together. The first sliding groove is located through the middle of the cleaning plate 7, and the second sliding groove is opened at the bottom end of the cleaning plate 7. The push plate 9 is composed of a first sliding plate located in the first sliding groove and a second sliding plate located in the second sliding groove. The width of the first sliding plate is smaller than the width of the first sliding groove. The end of the first sliding plate is provided with a rectangular protrusion to ensure that the push plate 9 and the cleaning plate 7 can rotate slightly at a small angle horizontally.

[0030] Working principle: In the initial state, the cleaning plate 7 is horizontally attached to the filter plate 2, and the movable plate 4 and the rotating plate 10 are also horizontally distributed. The first sliding plate presses against the end of the first sliding groove (near the end of the sealing plate 12).

[0031] In the initial state, when it is necessary to store the cleaning plate 7, the movable plate 4, and the rotating plate 10 (switching to a more vertical position to avoid the horizontal position affecting the flow of the medicine), even when the cleaning plate 7 is far away from the filter plate 2: By retracting the telescopic end of the telescopic component 5, the movable plate 4 is pulled, causing the end of the movable plate 4 to press against the sealing plate 12 and slide along the sealing plate 12, thereby tilting the movable plate 4. The movable plate 4 drives the cleaning plate 7 to tilt upward and stand upright, moving the cleaning plate 7 away from the filter plate 2. Under the action of the rotating rod 11, the rotating plate 10 tilts synchronously, thereby causing the rotating plate 10, the movable plate 4, and the cleaning plate 7 to switch to a more vertical state, fitting against the inner wall of the main unit 1, reducing the impact on the flow of the medicine. The telescopic component 5 can be controlled by setting a storage control key on the main unit 1.

[0032] In the initial state, when the filter plate 2 needs to be cleaned (the telescopic component 5 can be controlled by a cleaning control key on the main body): First, extend the telescopic end of the telescopic component 5, thereby driving the U-shaped plate 13, the insert rod 6, the movable plate 4, and the push plate 9 to move horizontally along the cleaning plate 7. The connecting rod 18 slides in the first groove, and the cleaning plate 7 remains in this position without moving. The moving push plate 9 pushes the top surface of the filter plate 2 to clean it. When the connecting rod 18 moves to the other end of the first slide groove, the end of the movable plate 4 presses against the middle of the inclined rotating rod 11. The movable plate 4 tilts under the reaction force, which causes the angle between the movable plate 4 and the insertion rod 6 to change. Then, the telescopic end of the telescopic component 5 continues to extend, and the horizontally rotating movable plate 4, in conjunction with the connecting rod 18, drives the cleaning plate 7 to start rotating (the cleaning plate 7 rotates with the end of the rotating rod 11 as the rotation center, that is, with the axis of the filter plate 2 as the rotation center); at the same time, the push plate 9, which is extending, makes a circular motion, thereby completing the cleaning of the general area of ​​the top surface of the filter plate 2 (since the movable plate 4 cannot pass the rotating rod 11, only half of the top surface of the filter is cleaned). During the reciprocating motion of the movable plate 4 at a certain angle in the horizontal direction, the inclined movable plate 4 is in contact with the rotating rod 11, and with the action of the arc plate 20 on the mating plate 21, the movable plate 4 overcomes the action of the threaded parts, causing the rotating rod 11 to rotate relative to the rotating plate 10, thereby causing the rotating plate 10 to rotate to the other side, so that the tilt angle changes symmetrically from the initial state. Next, retract the telescopic end of the telescopic component 5 (retract to the initial state, without excessive retraction to avoid storage). At this time, both the cleaning plate 7 and the movable plate 4 are in the initial state, and only the tilt angle of the rotating rod 11 changes (the tilt angle in the horizontal direction, with the tilt direction opposite to the initial tilt direction). Then, extend the telescopic end of the telescopic component 5. When the end of the movable plate 4 contacts the rotating rod 11, since the tilt direction of the rotating rod 11 has changed, although the movable plate 4 is horizontally tilted, the tilt direction is opposite, so that the push plate 9 and the cleaning plate 7 clean the other half of the filter plate 2, completing the cleaning of the entire filter plate 2, and at the same time, readjust the tilt direction of the rotating rod 11. Finally, retract the telescopic end of the telescopic component 5 (retract to the initial state, without excessive retraction to avoid over-retraction). At this time, both the cleaning plate 7 and the movable plate 4 are in the initial state, and the tilt direction of the rotating rod 11 is consistent with the initial state. In the above manner, the filter plate 2 can be cleaned multiple times.

[0033] When the movable plate 4 initially touches the rotating rod 11, it cannot overcome the effect of the threaded part, and the rotating rod 11 does not change relative to the rotating plate 10. Instead, it reacts to the movable plate 4, causing the movable plate 4 to tilt along the tilting direction of the rotating rod 11. However, when the connecting rod 18 presses tightly against the other end of the first slide groove, it drives the tilted movable plate 4 to reciprocate (driving the cleaning plate 7 to make a circular motion), thus overcoming the effect of the threaded part and causing the rotating rod 11 to change relative to the rotating plate 10.

[0034] It is worth noting that during the relative angular rotation between the insertion rod 6 and the movable plate 4 (i.e., when the angle of the movable plate 4 changes), the insertion rod 6 and the second pressing ball 16 located on the insertion rod 6 rotate relative to the movable plate 4. The second pressing ball 16 and the first pressing ball 14 rotate and contact each other, pressing against each other. With the help of the spring 17, the movable plate 4 swings up and down relative to the insertion rod 6. In this application, by limiting the size of the slot opened on the movable plate 4 for the insertion rod 6 to move, the swing amplitude of the movable plate 4 is small, thereby driving the push plate 9 to swing up and down slightly at the same time, which is more conducive to cleaning the top surface of the filter plate 2.

[0035] In this application, when the cleaning plate 7 and the push plate 9 clean the filter plate 2, the rotating plate 10 and the cleaning plate 7 and the push plate 9 make a slight shaking motion, which helps to clean the filter plate 2 (the filter screen generally has slight elasticity).
