Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, and in particular to an intermittent atomizer. Background Technology

[0002] Medical nebulizers are primarily used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity. Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. It utilizes the principle of gas jet propulsion, where a high-speed airflow carries liquid against an obstruction, suspending tiny water droplets in the gas to form an aerosol that is then delivered into the respiratory tract for humidification or drug inhalation. This method acts directly on the affected area, offering advantages such as small dosage, rapid onset of action, minimal side effects, and ease of use, resulting in significant therapeutic effects and high local drug concentrations in the respiratory tract.

[0003] Currently, traditional medical nebulizers have a fixed spray rate at the factory. Each nebulizer, driven by a medical gas source and containing medication in the nebulizer cup, continuously sprays at a fixed rate. However, human respiration occurs with each inhalation and exhalation. Nebulized medication particles are only inhaled during inhalation. During exhalation, because the medication is still atomizing, the patient's exhalation creates resistance to the exhaled air, causing the medication to be blown out of the nebulizer cup, resulting in medication leakage and waste. This fixed, continuous spray does not effectively utilize the medication and also leads to waste. To improve the adaptability of the nebulizer spray and enhance the effectiveness and utilization rate of nebulized medication, this intermittent spray nebulizer was designed and developed. Summary of the Invention

[0004] The purpose of this invention is to provide an intermittent nebulizer, which aims to solve the technical problem of drug waste caused by fixed continuous spraying in existing traditional medical nebulizers.

Detailed Implementation

[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2As shown in the figure, an intermittent nebulizer provided by this utility model includes a cup body 1 and a cup lid 2 that is sealed to the top of the cup body 1. The bottom of the cup body 1 has an air inlet pipe 3 connected to a driving air source. The lower part of the inner cavity of the cup body 1 has a drug storage chamber 4, and the middle part has a nebulizing mechanism connected to the air inlet pipe 3. The nebulizing mechanism is used to atomize the liquid medicine in the drug storage chamber 4 and discharge it from the mist outlet 5 on the side wall of the cup body 1. The top of the cup lid 2 has a top cover, and there is a gap between the mating surfaces of the two that communicates with the outside. The lower part of the cup lid 2 has a vent hole that communicates with the outside. The top cover 6 and the cup lid 2 have an adjustment mechanism that cooperates with the vent hole and the nebulizing mechanism to control whether the nebulizer outputs mist normally when the user inhales, does not output mist when the user exhales, or outputs mist continuously. This solution can achieve intermittent nebulization, effectively saving nebulized medication and improving drug utilization; at the same time, it allows nebulization therapy to better coordinate with the patient's breathing, improving the effectiveness and adaptability of nebulization therapy.

[0033] In specific embodiments of this utility model, such as Figure 2 , 3 As shown, the adjustment mechanism includes a connecting shaft 7, a valve plate 8, a rocker arm 9, and an adjustment plate 22. Both ends of the connecting shaft 7 are rotatably engaged with the inner wall of the cup lid 2. The upper ends of the valve plate 8 and the rocker arm 9 are fixedly connected to the connecting shaft 7. The valve plate 8 can block the vent hole at the bottom of the cup lid 2. The lower end of the rocker arm 9 is connected to the impact plate 10 of the atomizing mechanism. The lower cavity of the cup lid 2 has a V-shaped groove 11 communicating with the inner cavity of the cup body 1. The rocker arm 9 and the impact plate 10 extend downwards into the V-shaped groove 11. In the middle of section 1, the connecting shaft 7 is positioned above the V-groove 11; the V-groove 11 consists of semi-enclosed cavities with sealed bottoms and sidewalls on both sides and open tops; the vent is located on one sidewall of the V-groove 11, the valve plate 8 is located within the cavity containing the vent, and the adjusting plate 22 is located at the bottom of the top cover 6. The adjusting plate 22, as the top cover 6 rotates, drives the valve plate 8 to seal the vent, ensuring that the impact plate 10 remains in the atomizing position, thus achieving continuous mist output from the atomizer. When the top cover 6 is in a horizontal position, the adjusting plate 22 disengages from the valve plate 8, and the valve plate 8 swings relative to the vent under the influence of the breathing airflow, opening and closing the vent, thereby causing the impact plate 10 to change between tilted and vertical states, ensuring that the atomizer does not produce mist during exhalation but produces normal mist during inhalation. Figure 4 , 5 As shown.

[0034] During installation, the top of the rocker arm 9 is connected to the connecting shaft 7 via a connecting plate. The two ends of the connecting shaft 7 are located in the shaft holes on the inner wall of the cup lid 2. After installation, the valve plate 8 can swing around the connecting shaft 7 with the rocker arm 9. Figure 3 The black arrow in the diagram indicates the direction of rotation of connecting shaft 7.

[0035] In specific embodiments of this utility model, such as Figure 2 As shown, the atomizing mechanism includes a striking plate 10, a conical cup core 12, and an air outlet pipe 13. The conical air outlet pipe 13 is located at the top of the air inlet pipe 3. The cup core 12 is located inside the drug storage chamber 4 and is fitted onto the outside of the air outlet pipe 13. There is a sandwich between the cup core 12 and the air outlet pipe 13. The top of both the cup core 12 and the air outlet pipe 13 are provided with an outlet. There is a gap between the bottom of the cup core 12 and the bottom of the drug storage chamber 4 for the liquid medicine to pass through. This atomizing mechanism utilizes the Venturi principle. An external driving air source enters the outlet pipe through the inlet pipe at the bottom of the cup. The airflow is accelerated when it passes through the small hole at the tip of the outlet pipe. The accelerated airflow at the tip creates a negative pressure at the top of the interlayer, forming a pressure difference between the top and bottom of the tip. Under the action of the pressure difference, the liquid in the drug storage chamber is sent to the top of the tip along the inlet and outlet pipes. At the same time, carried by the airflow at the tip, it impacts the vertical impact plate above, breaking it into tiny aerosol particles. Driven by the airflow inside the cup, these particles are sprayed out from the mist outlet.

[0036] To further optimize the above structure, the cup core 12 is provided with multiple lifting arms 14 on its exterior. The upper end of each lifting arm 14 is connected to a connecting ring 15, which abuts against the bottom of the cavities on both sides of the V-groove 11 of the cup lid 2. Since the cup core is installed using its conical shape, it has no fixed orientation; it can be dropped freely with the conical opening facing downwards. The cup core's position is corrected by the conical tip of the air outlet pipe. The cup core can be installed without a specific angle, making installation convenient. To prevent excessive swaying of the cup core during use, lifting arms are installed on the outer wall of the cup core. The connection between the connecting ring and the bottom of the V-groove ensures relative stability of the cup core's position.

[0037] In specific embodiments of this utility model, such as Figure 2 , 3 As shown, the valve plate 8 includes a one-way valve plate 16 and a rectangular plate 17 with a circular vent hole. The upper end of the rectangular plate 17 is fixedly connected to the connecting shaft 7. The circular vent hole is located at the lower part of the rectangular plate 17, and a grid plate 18 is provided inside the circular vent hole. The one-way valve plate 16 is located on the side of the circular vent hole facing the rocker arm 9, and the middle part of the one-way valve plate 16 is connected to the center of the grid plate 18. The one-way valve plate is made of soft silicone. A mounting shaft is provided in the middle of the grid plate inside the circular vent hole on the rectangular plate for mounting the soft silicone valve plate. The grid plate with the vent grid prevents the one-way valve plate from being recessed into the vent hole, thus preventing the one-way valve plate from failing to seal the vent hole properly. The vent hole, grid plate, and one-way valve plate on the rectangular plate together form a structure that allows for unidirectional airflow and can rotate around the connecting shaft.

[0038] In the specific design, the mist outlet 5 is located on the upper side wall of the cup body 1 and is positioned opposite to the valve plate 8; the lower outer side of the semi-enclosed cavity opposite to the valve plate 8 is provided with an inwardly recessed guide groove 19 opposite to the mist outlet 5, which is used to guide the airflow exhaled by the user into the cup body 1.

[0039] In specific embodiments of this utility model, such as Figure 1 , 6 As shown, the edge of the top cover 6 is rotatably engaged with the cup lid 2 via two symmetrical mounting shafts 20. Two opposing pressing parts 21 are provided on the top surface of the movable edge of the top cover 6. The bottom of the top cover 6 has multiple adjusting plates 22 and a semi-cylindrical closed cavity 23 that engages with the inner wall of the cup lid 2. The multiple adjusting plates 22 are arranged in parallel at intervals and are positioned below the two pressing parts 21, opposite to the semi-cylindrical closed cavity 23. The multiple adjusting plates 22 are correspondingly positioned above the valve plate 8, and the lower part of each adjusting plate 22 has a beveled edge that can fit against the outer surface of the valve plate 8. The mounting shaft 20 includes a connecting part and a cylindrical rotating shaft. The upper end of the connecting part is connected to the top cover, and the lower end is connected to the rotating shaft. The inner wall of the cup lid 2 has a mounting post 24 that rotatably engages with the rotating shaft. The top of the mounting post is an arc-shaped groove with an upward opening, which rotatably engages with the rotating shaft. The arc-shaped groove is an abaxial groove capable of accommodating the rotating shaft, and the end of the rotating shaft has a limiting platform for limiting its movement. The top cover with the above structure makes the atomizer more harmonious and aesthetically pleasing overall. In actual manufacturing, the mounting shaft and top cover, as well as the mounting post and cup cover, can all be integrally injection molded.

[0040] In the specific production process, such as Figure 8 , 9 As shown, a lever 25 is provided on the inner side of the mounting shaft 20. The upper end of the lever 25 is rotatably connected to the mounting shaft 20 via a torsion spring (not shown in the drawing). A protrusion 32 is provided on the outer side of the lower end of the lever 25. A limiting groove 33 that mates with the protrusion 32 is provided on the inner side of the mounting post 24. The lower end of the limiting groove has an arc-shaped groove, which serves to slide and limit the movement when the top cover is pressed. As the top cover is opened or closed, the protrusion slides to both ends of the arc-shaped groove, and the torsion spring enables the top cover to return to its original position.

[0041] When assembling the cup body and lid, such as Figure 1 , 7 As shown, the top edge of the cup body 1 is provided with a mounting groove 26, which includes an inclined section and a horizontal section. The outer wall of the cup lid 2 is provided with a corresponding protrusion 27 that can slide along the inclined end of the mounting groove 26 to the horizontal section. The root of the mounting groove 26 is provided with a positioning groove that mates with the protrusion 27. An upwardly protruding locking protrusion 28 is provided on the edge of the mounting groove 26 adjacent to the positioning groove. A connecting buckle 29 is provided on the outer wall of the cup lid 2 below the locking protrusion 28. A corresponding sliding groove (not shown in the figure) is provided on the side wall of the cup body 1 that mates with the connecting buckle 29. When installing the cup lid, the connecting buckle is tightened clockwise along the cup body. The protrusion of the cup lid reaches the locking protrusion along the mounting groove and passes over the locking protrusion, thus locking the cup lid. Simultaneously, the outer wall of the inner ring of the cup lid fits against the inner wall of the top opening of the cup body, providing a sealing effect.

[0042] The working principle of this utility model is as follows:

[0043] like Figure 5 As shown, during inhalation, the valve plate 8, driven by the user's inhalation airflow, seals the top cover 6 against the cup lid 2. Only the vent hole on the valve plate 8 has a gap inside the cup body 1. Outside air 31 passes through the top cover 6 and opens the one-way valve 16 through the vent hole in the V-shaped groove 11 at the bottom of the cup lid 2, entering the cup body 1. Simultaneously, the external airflow compresses the plane of the valve plate 8, causing the valve plate 8 to adhere tightly to the inclined surface of the V-shaped groove 11 under the action of gravity and compression, making the head of the impact plate 10 vertically downwards, and the lower end of the impact plate 10... A narrow space is formed between the top of the cup core 12 and the cone tip of the air outlet 13. The driving air source (compressed air) blown in through the air inlet pipe 3 at the bottom of the cup body 1 flows at high speed in the narrow area of ​​the cone tip, creating negative pressure. Under the action of the Venturi principle, the liquid medicine in the medicine storage chamber 4 is drawn to the top of the air outlet 13 and impacts the head of the impact plate 10 through the cone tip outlet, forming micron-sized aerosol particles. The aerosol particles 30 are inhaled by the user under the action of compressed air and the airflow of the user's inhalation. During the inhalation process, the atomizer produces mist normally.

[0044] Conversely, such as Figure 4 As shown, during exhalation, the exhaled air enters the cup body 1 through the mist outlet 5. The airflow exerts force on the valve plate 8 and the one-way valve plate 16 through the vent hole on one side of the V-shaped groove 11. The one-way valve plate 16 blocks the vent hole on the valve plate 8, thereby driving the valve plate 8 to swing upward. At the same time, it causes the impact plate 10 to deviate from the top of the cup core 12. A negative pressure area cannot be formed at the cone tip of the cup core 12 and the air outlet tube 13, thus preventing atomization. The airflow finally flows upward along the inner cavity of the cup lid 2 and is discharged through the edge of the top cover 6. During exhalation, the atomizer does not produce mist.

[0045] Additionally, by pressing the front and rear pressing parts 21 of the top cover 6, when the pressing parts 21 are in a horizontal state, the adjusting plate 22 moves away from the valve plate 8, and the valve plate 8 can swing normally under the inhalation / exhalation airflow. Consequently, the impact plate 10 deviates from or is aligned with the spray cone tip of the cup core 12, allowing the atomizer to switch between not producing mist and producing mist with each breath. Figure 2 As shown, when the front pressing part 21 of the top cover 6 is pressed, the adjusting plate 22 is pressed against the plane of the valve plate 8, and the valve plate 8 cannot move, so that the atomizer can spray continuously and the mist output does not change with breathing.

[0046] In summary, this invention enables intermittent nebulization in sync with the user's breathing, effectively saving nebulized medication, improving drug utilization, and reducing medication dosage. By employing this invention, the mist output of the nebulizer can be controlled according to actual conditions, achieving both intermittent and continuous nebulization, thus better coordinating nebulization therapy with the patient's breathing and improving the effectiveness and adaptability of nebulization therapy.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
