Description

Technical Field

[0001] This invention relates to the field of aerosol bottle technology, specifically to an atomizing accessory for a compressed bottle. Background Technology

[0002] Compressor nebulizers are commonly used nebulized inhalation therapy devices in clinical and home settings. They use a compressor pump to generate high-pressure airflow, driving the nebulizer accessory to atomize liquid, allowing medication to directly reach the respiratory tract lesions. Traditionally, these devices use compressed gas cylinders, creating a pressure difference between the inside and outside of the cylinder by connecting it to the atmosphere, which then sprays the liquid. However, this method results in highly unstable pressure initially, followed by very low pressure as the liquid diminishes. Electronic nebulizers, on the other hand, use disposable medication in the nebulizer chamber, meaning the dosage cannot be adjusted as needed, and any remaining liquid is wasted.

[0003] To overcome the aforementioned deficiencies, prior art (Chinese patent CN215275166U, published on 2021-12-24) discloses a nebulizer mask for airway humidification in tracheostomy patients, comprising a nebulizer bottle and an electric telescopic rod. The key feature is that a corrugated tube is fixedly installed at the top of the nebulizer bottle, and a nebulization volume control chamber is fixedly installed at the end of the corrugated tube away from the nebulizer bottle. A push rod is slidably connected inside the nebulization volume control chamber, and a rubber end cap is fixedly installed at one end of the push rod. A telescopic rod slide is fixedly installed at the top of the nebulization volume control chamber. The advantages of this invention are: the electric telescopic rod is activated by a controller, driving the push rod to allow the nebulized liquid to be absorbed by the patient through the nebulizer mask. This allows the patient to freely control the speed of medication absorption via the controller, and also facilitates the patient's ability to freely and quantitatively absorb the medication. The end of the guide rod is equipped with a first gear meshing with an adjusting gear, and its position is adjusted via a metal adjusting rod, reducing the workload of nurses and making it convenient for patients to use, eliminating the need to manually hold the nebulizer bottle for absorption.

[0004] Prior art 2 (Chinese Patent No. CN210750700U, Publication Date: 2020-06-16) discloses a nebulizer for respiratory medicine, comprising a nebulizer bottle, a label, a supply tube, a ventilation tube, and a roller. The label is fixed to the surface of the nebulizer bottle. A supply tube is installed inside the nebulizer bottle, with one end extending to the outside of the nebulizer bottle. One end of the supply tube is corrugated, and a heat-insulating structure is fixed to one end of the supply tube on one side of the corrugated tube. A face mask is fixed to the bottom of the supply tube, and an anti-overflow structure is installed at the bottom of the face mask. Fixing ropes are installed on both sides of the face mask, and an elastic rope is fixed at the center of the fixing ropes. A ventilation tube is fixed to one side of the supply tube, and a one-way valve is installed on the surface of the ventilation tube. This not only improves the convenience of using the nebulizer and avoids respiratory irritation during use, but also avoids medication waste.

[0005] The aforementioned mechanisms reduce drug waste by controlling the liquid absorption rate. However, in actual use, the amount of liquid absorbed per press is consistent. When adding liquid, it is usually necessary to prepare enough liquid at once. However, adding enough liquid at once may result in too much liquid. Excessive liquid will cause it to splash and overflow directly under the impact of airflow during atomization, which not only wastes liquid but may also enter the airflow channel or mist outlet, causing pipeline contamination and blockage, and affecting the service life of subsequent atomization accessories. Summary of the Invention

[0006] The purpose of this invention is to provide an atomizing accessory for compressed bottles, addressing the problem described in the background art where controlling the liquid intake speed reduces drug waste. However, in actual use, the amount of liquid drawn per press is consistent, and when adding liquid, it is usually necessary to prepare enough liquid at once. Adding too much liquid at once can lead to excess liquid. Excess liquid causes splashing and overflow during atomization under the impact of the airflow, not only wasting liquid but also potentially entering the airflow channel or mist outlet, causing contamination and blockage of the tubing, and affecting the service life of subsequent atomizing accessories.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an atomizing accessory for a compressed bottle, comprising a pressing head, a compressed gas medicine bottle disposed on the side of the pressing head, and a nozzle disposed on the side of the pressing head; a liquid tank is engaged with the outer side of the pressing head via a connecting rib, and an atomizing mask is engaged with the side of the liquid tank; an atomizing plate is installed on the side of the atomizing mask near the liquid tank; a partitioning mechanism for dividing the liquid tank is disposed inside the liquid tank; a scraping mechanism for cleaning the inner wall of the liquid tank is disposed at the middle position inside the liquid tank; and a lubrication spraying mechanism for lubricating the gear set is disposed outside the liquid tank.

[0008] Furthermore, the separating mechanism includes a separating box, which is disposed at the lower end of the liquid tank. A separating plate is rotatably connected inside the liquid tank, and the left and right sides of the separating plate are in contact with the side walls inside the liquid tank. The separating plate is disposed above the separating box.

[0009] Furthermore, the scraping mechanism includes a knob, which is located on the outside of the liquid tank. An adjusting gear is installed at the end of the knob, and a second gear is engaged on the side of the adjusting gear. A threaded rod is installed at the end of the second gear, and a movable block is threadedly connected to the outside of the threaded rod. A first scraper is installed at the bottom of the movable block via a connecting rod.

[0010] Furthermore, a rubber block is installed at the bottom of the first scraper, and the side of the rubber block is in contact with the inside of the liquid tank.

[0011] Furthermore, a slide rail is provided on the side of the movable block, and a slider that matches the slide rail is installed on the side of the movable block. The movable block and the slide rail are connected by a sliding connection between the slider and the slide rail to form a sliding mechanism.

[0012] Furthermore, a sliding block is hinged to the right side of the movable block via a connecting rod, and a second scraper is installed at the bottom end of the sliding block, with the surface of the second scraper in contact with the surface of the partition plate.

[0013] Furthermore, a guide rod is provided inside the liquid tank, and a sliding block is slidably connected to the outside of the guide rod. A first gear that meshes with the adjusting gear is installed at the end of the guide rod.

[0014] Furthermore, torsion springs are wound around both ends of the guide rod, and the guide rod and the liquid tank form an elastic structure through the elastic force of the torsion springs.

[0015] Furthermore, the lubrication spraying mechanism includes a cam, which is rotatably connected to the surface of the liquid tank. The knob is connected to the cam via a synchronous belt pulley transmission mechanism. An air bladder is provided on the side of the cam, and a return spring is installed at both the top and bottom of the air bladder. A nozzle is connected to the front end of the air bladder via a hose, and the nozzle is positioned above the second gear.

[0016] Furthermore, a connecting spring is wound around the outside of the knob, and a mounting plate is installed at the end of the knob. Matching magnets are installed on both the mounting plate and the inner wall of the liquid tank.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The liquid is stored inside the compressed gas vial. Upon pressing the nozzle, the liquid is sprayed into the liquid tank. A separator separates the sprayed liquid. When the separator is not obstructed, the liquid enters the separator box, awaiting atomization by the atomizing plate. The separator keeps the liquid in the tank and separator box. The tank holds the total amount of liquid to be inhaled, while the separator box contains the liquid to be atomized, preventing incomplete atomization due to excessive liquid being atomized at once and improving atomization stability.

[0018] Furthermore, by rotating the knob, the adjusting gear and the second gear mesh with each other. When it is necessary to scrape the inner wall of the liquid tank and the surface of the partition plate, the knob is pressed into the protective box, which causes the connecting spring to be stressed and shorten its length. At the same time, the two sets of magnets attract each other, and the adjusting gear and the first gear mesh with each other. As the adjusting gear rotates, it drives the first gear to rotate. When the first gear rotates, it drives the threaded rod to rotate simultaneously. The movable block threaded to the outside of the threaded rod is thus driven to move. When the movable block moves outside the threaded rod, it drives the first scraper to move. The first scraper scrapes the inclined surface at the bottom of the liquid tank, reducing liquid residue. This makes it easier to add sufficient liquid to the interior of the partition box later, avoiding problems such as insufficient liquid due to liquid residue inside the liquid tank.

[0019] Furthermore, when the movable block moves, it drives the sliding block to move via a connecting rod. The sliding block, in turn, drives the second scraper to move synchronously. The second scraper then cleans the surface of the liquid tank. Since the sliding block and the movable block are rotatably connected via a connecting rod, when the angle of the liquid tank changes, the second scraper can be deflected synchronously by the force of the torsion spring. This ensures that the bottom of the second scraper is always in contact with the surface of the partition plate and can effectively scrape and clean the liquid, thus reducing liquid residue.

[0020] 2. When the knob is rotated, the synchronous belt pulley transmission mechanism drives the cam to rotate. When the cam rotates, it will continuously squeeze the airbag, causing the lubricating oil inside the airbag to be sprayed out from the nozzle. After the airbag is squeezed, the spring force of the return spring will reset the position, so that the airbag returns to the initial state and continues to squeeze and spray out the lubricating oil.

[0021] Furthermore, after the lubricating oil is sprayed out, it will drip onto the surface of the second gear. By adjusting the meshing between the gear and the first gear, the surface of the adjusting gear comes into contact with the lubricating oil. At the same time, the adjusting gear will also mesh with the second gear, thus preventing wear during subsequent use of the gear set. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figure 1 - Figure 5The technical solution presented aims to reduce drug waste by controlling the liquid absorption rate. However, in actual use, the amount of liquid absorbed per press is consistent. When adding liquid, it is usually necessary to prepare enough liquid at once, but this may result in excess liquid. Excess liquid will cause splashing and overflow during atomization under the impact of the airflow, not only wasting liquid but also potentially entering the airflow channel or mist outlet, leading to pipeline contamination and blockage, and affecting the service life of subsequent atomizing accessories. The disclosed atomizing accessory for compressed bottles includes a separating mechanism, including a pressing head. 1. A compressed gas bottle 2 is provided on the side of the pressing head 1, and a nozzle 5 is provided on the side of the pressing head 1. A liquid tank 3 is engaged with the outer side of the pressing head 1 through a connecting bone 8, and an atomizing mask 7 is engaged with the side of the liquid tank 3. An atomizing plate 6 is installed on the side of the atomizing mask 7 near the liquid tank 3. A partition mechanism for dividing the liquid tank 3 is provided inside the liquid tank 3. The partition mechanism includes a partition box 4, and the partition box 4 is located at the lower end of the liquid tank 3. A partition plate 9 is rotatably connected inside the liquid tank 3, and the left and right sides of the partition plate 9 are attached to the side wall inside the liquid tank 3. The partition plate 9 is located above the partition box 4.

[0034] In this example, the liquid is stored inside the compressed gas bottle 2. By pressing the press head 1, the liquid is sprayed out from the nozzle 5 and enters the liquid tank 3. The sprayed liquid can be separated by the partition plate 9. When the partition plate 9 is not blocked, the liquid enters the partition box 4 and waits to be atomized by the atomizing plate 6.

[0035] By rotating the knob 10, the adjusting gear 11 is driven to rotate. When the adjusting gear 11 rotates, it meshes with the first gear 12, so that the first gear 12 can synchronously drive the partition plate 9 to rotate. After rotating 45°, the partition plate 9 is in a vertical state, so that the liquid sprayed from the nozzle 5 can enter the interior of the partition box 4 without obstruction, and be atomized by the atomizing plate 6.

[0036] The separator 9 can divide the liquid into the liquid tank 3 and the separator box 4. The liquid tank 3 can store the total amount of liquid to be inhaled, while the separator box 4 is filled with the liquid to be atomized. This avoids the situation where too much liquid is atomized at once, which would lead to incomplete atomization and improves the stability during atomization.

[0037] Example 2: Figure 1 - Figure 8The technical solution shown addresses the problem of liquid residue remaining on the lower side wall of the liquid tank 3 when it is placed inside for atomization. The atomizing accessory for the compression bottle discloses a scraping mechanism. A scraping mechanism for cleaning the inner wall of the liquid tank 3 is located in the middle of the tank. The scraping mechanism includes a knob 10, which is located on the outside of the liquid tank 3. An adjusting gear 11 is installed at the end of the knob 10, and a second gear 13 meshes with the side of the adjusting gear 11. A threaded rod 14 is installed at the end of the second gear 13, and a movable block 15 is threadedly connected to the outer side of the threaded rod 14. A first scraper 16 is installed at the bottom of the movable block 15 via a connecting rod. A rubber block 27 is installed at the bottom of the first scraper 16. The side of the rubber block 27 is in contact with the inner side of the liquid tank 3; the side of the movable block 15 is provided with a slide rail 21, and the side of the movable block 15 is equipped with a slider 22 that matches the slide rail 21. The movable block 15 and the slide rail 21 are connected by a sliding connection between the slider 22 and the slide rail 21 to form a sliding mechanism; the right side of the movable block 15 is hinged with a sliding block 19 by a connecting rod. The bottom end of the sliding block 19 is equipped with a second scraper 17, and the surface of the second scraper 17 is in contact with the surface of the partition plate 9; the inside of the liquid tank 3 is provided with a guide rod 18, and the sliding block 19 is slidably connected to the outside of the guide rod 18; the front and rear ends of the guide rod 18 are both wound with torsion springs 20, and the guide rod 18 and the liquid tank 3 are connected by the elastic force of the torsion springs 20 to form an elastic structure.

[0038] In this example, by rotating the knob 10, the adjusting gear 11 and the second gear 13 mesh with each other. When it is necessary to scrape the inner wall of the liquid tank 3 and the surface of the partition plate 9, the knob 10 is pressed into the protective box, which causes the connecting spring 30 to be stressed and shorten its length. At the same time, the two sets of magnets 28 attract each other, and the adjusting gear 11 and the first gear 12 mesh with each other. As the adjusting gear 11 rotates, it drives the first gear 12 to rotate. When the first gear 12 rotates, it drives the threaded rod 14 to rotate. The movable block 15, which is threaded to the outside of the threaded rod 14, is thus driven to move. When the movable block 15 moves outside the threaded rod 14, it drives the first scraper 16 to move. The first scraper 16 scrapes the inclined surface at the bottom of the liquid tank 3 to reduce liquid residue. This makes it easier to add sufficient liquid when adding liquid to the interior of the partition box 4 later, avoiding problems such as insufficient liquid caused by liquid residue inside the liquid tank 3.

[0039] When the movable block 15 moves, it drives the sliding block 19 to move via the connecting rod. The sliding block 19 then drives the second scraper 17 to move synchronously. The second scraper 17 then cleans the surface of the liquid tank 3. The sliding block 19 and the movable block 15 are rotatably connected via the connecting rod. Therefore, when the angle of the liquid tank 3 changes, the second scraper 17 can be deflected synchronously by the elastic force of the torsion spring 20. This ensures that the bottom end of the second scraper 17 can always be in contact with the surface of the partition plate 9 to scrape and clean, effectively reducing liquid residue.

[0040] During the movement of the movable block 15, it will drive the slider 22 to move. The slider 22 then slides inside the slide rail 21. The cooperation between the slide rail 21 and the slider 22 makes the movement of the movable block 15 smoother and avoids jamming.

[0041] Example 3: Figure 1 , Figure 3 and Figure 9 The technical solution shown addresses the potential for jamming and wear between the adjusting gear 11, the first gear 12, and the second gear 13 during liquid scraping. The atomizing accessory for the compression bottle discloses a lubrication spray mechanism. The external surface of the liquid tank 3 is equipped with this mechanism for lubricating the gear set. The lubrication spray mechanism includes a cam 23, which is rotatably connected to the surface of the liquid tank 3. A knob 10 is connected to the cam 23 via a synchronous belt pulley transmission mechanism. An air bladder 24 is provided on the side of the cam 23, and a return spring 25 is installed at both the top and bottom of the air bladder 24. A nozzle 26 is connected to the front end of the air bladder 24 via a hose, and the nozzle 26 is positioned above the second gear 13. A connecting spring 30 is wound around the outside of the knob 10, and a mounting plate 29 is installed at the end of the knob 10. Matching magnets 28 are installed on both the mounting plate 29 and the inner wall of the liquid tank 3.

[0042] In this example, when the knob 10 is rotated, it drives the cam 23 to rotate through the synchronous belt pulley transmission mechanism. When the cam 23 rotates, it continuously squeezes the airbag 24, causing the lubricating oil inside the airbag 24 to be sprayed out from the nozzle 26. After the airbag 24 is squeezed, it is reset in position by the elastic force of the return spring 25, so that the airbag 24 returns to its initial state and performs repeated squeezing to spray out the lubricating oil.

[0043] After the lubricating oil is sprayed out, it will drip onto the surface of the second gear 13. By adjusting the meshing between the gear 11 and the first gear 12, the surface of the adjusting gear 11 comes into contact with the lubricating oil. At the same time, the adjusting gear 11 and the second gear 13 will also mesh, so that the gear set can avoid wear during subsequent use.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
