Description

Technical Field

[0001] The invention relates to the technical field of atomization equipment, in particular to an intermittent atomizer. Background Art

[0002] Medical nebulizers are mainly 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 chest cavity. Atomization inhalation therapy is an important and effective treatment method for respiratory diseases. It mainly uses the principle of gas jet, and high-speed airflow drives the liquid to spray onto the obstruction, suspends the tiny droplets hit by water droplets in the gas, forms an aerosol and enters the respiratory tract for respiratory tract humidification or drug inhalation. This method acts directly on the lesion site, has the advantages of small dosage, quick effect, small side effects and easy use, and has significant efficacy and high local drug concentration in the respiratory tract.

[0003] At present, the spray rate of traditional medical nebulizers is fixed when they leave the factory. As long as each nebulizer is driven by a medical gas source and there is liquid medicine in the nebulizer cup, the nebulizer cup will continue to spray, and the spray rate is a fixed value. However, the human breathing process is completed between one breath and one breath. The atomized drug particles can only be inhaled when the patient inhales. When exhaling, because the drug is still atomizing, the patient's exhalation and the sprayed aerosol form a conflict, causing the atomized drug to be blown out of the nebulizer cup, and the drug particles leak out, resulting in drug waste. Fixed and continuous spraying cannot effectively utilize drugs, and also causes waste of atomized drugs. In order to improve the adaptability of atomized spray and improve the use effect and utilization rate of atomized drugs, this intermittent spray nebulizer is designed and developed.

DETAILED DESCRIPTION

[0031] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

The use of this scheme can realize intermittent atomization, effectively save atomized drugs, and improve drug utilization; at the same time, the atomization treatment can be better coordinated with the patient's breathing, and the effectiveness and adaptability of atomization treatment can be improved.

[0033] In a specific embodiment of the present invention, Figure 2 , 3 As shown, the regulating mechanism includes a connecting shaft 7, a valve plate 8, a swing rod 9 and an regulating plate 22. Both ends of the connecting shaft 7 are rotatably matched with the inner wall of the cup cover 2. The upper ends of the valve plate 8 and the swing rod 9 are fixedly connected to the connecting shaft 7. The valve plate 8 can block the air vents at the bottom of the cup cover 2. The lower end of the swing rod 9 is connected to the impact plate 10 of the atomization mechanism. A V-shaped groove 11 communicating with the inner cavity of the cup body 1 is provided in the middle of the lower cavity of the cup cover 2. The swing rod 9 and the impact plate 10 extend downward in the V-shaped groove 11. 1, the connecting shaft 7 is arranged above the V-shaped groove 11; both sides of the V-shaped groove 11 are semi-enclosed cavities with the bottom and side walls blocked and the top open; the air hole is arranged on a side wall of the V-shaped groove 11, the valve plate 8 is arranged in the cavity on the side where the air hole is located, and the adjustment plate 22 is arranged at the bottom of the top cover 6, and the adjustment plate 22 can drive the valve plate 8 to block the air hole as the top cover 6 rotates so that the impact plate 10 is always in the atomization position, thereby achieving continuous mist discharge from the nebulizer. When the top cover 6 is in a horizontal position, the adjustment plate 22 is separated from the valve plate 8, and the valve plate 8 swings relative to the air hole driven by the respiratory airflow, thereby achieving the opening and blocking of the air hole, and then driving the impact plate 10 to change between the skewed and vertical states, thereby achieving the nebulizer not discharging mist during exhalation and discharging mist normally during inhalation, such as Figure 4 , 5 shown.

[0034] During specific installation, the top of the swing rod 9 is connected to the connecting shaft 7 through a connecting plate, and both ends of the connecting shaft 7 are arranged in the shaft holes on the inner wall of the cup cover 2. After installation, the valve plate 8 can swing around the connecting shaft 7 with the swing rod 9. Figure 3 The black arrow in shows the rotation direction of the connecting shaft 7.

[0035] In a specific embodiment of the present invention, Figure 2As shown, the atomization mechanism includes a collision plate 10, a conical cup core 12 and an air outlet pipe 13. The conical air outlet pipe 13 is arranged at the top of the air inlet pipe 3. The cup core 12 is arranged in the medicine storage bin 4 and is sleeved on the outside of the air outlet pipe 13. An interlayer is provided between the cup core 12 and the air outlet pipe 13. The tops of the cup core 12 and the air outlet pipe 13 are both provided with outlets. A gap is provided between the bottom of the cup core 12 and the bottom of the medicine storage bin 4 for the passage of liquid medicine. The atomization mechanism utilizes the Venturi principle. An external driving air source enters the air outlet pipe through the air inlet pipe at the bottom of the cup body. The airflow is accelerated when passing through the small hole at the cone tip of the air outlet pipe. The airflow at the cone tip is accelerated to form a negative pressure at the top of the interlayer, and a pressure difference is formed between the top and the bottom of the cone tip. The liquid in the medicine storage chamber is sent to the top of the cone tip along the air inlet pipe and the air outlet pipe under the action of the pressure difference. At the same time, it is carried by the airflow at the cone tip and hits the vertical impact plate above, and is impacted into tiny aerosol particles, which are sprayed out from the mist outlet driven by the airflow in the cup body.

[0036] To further optimize the above structure, a plurality of suspension arms 14 are provided on the outside of the cup core 12, and the upper ends of the suspension arms 14 are connected to the connecting rings 15, and the connecting rings 15 are in contact with the bottom of the cavities on both sides of the V-shaped groove 11 of the cup cover 2. Since the cup core is installed by its cone, there is no fixed direction, and the cup core can be freely dropped with the cone mouth facing downward. The position of the cup core is corrected by the cone tip of the air outlet pipe. The cup core is installed without a specific angle, and the installation is convenient. In order to prevent the cup core from shaking too much during use, a suspension arm is installed on the outer wall of the cup core, and the connection ring cooperates with the bottom of the V-shaped groove to achieve a relatively stable position of the cup core.

[0037] In a specific embodiment of the present invention, Figure 2 , 3 As shown, the valve plate 8 includes a one-way valve disc 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 arranged at the lower part of the rectangular plate 17, and a grid plate 18 is arranged in the circular vent hole. The one-way valve disc 16 is arranged on the side of the circular vent hole facing the swing rod 9, and the middle part of the one-way valve disc 16 is connected to the center of the grid plate 18. The one-way valve disc adopts a soft silicone valve disc. A mounting shaft is arranged in the middle of the grid plate in the circular vent hole on the rectangular plate for mounting the soft silicone valve disc. The grid plate with a ventilation grille can prevent the one-way valve disc from sinking into the vent hole and prevent the one-way valve disc from not sealing the vent hole tightly. The vent hole, grid plate, and one-way valve disc on the rectangular plate together form a structure that can realize one-way airflow and can rotate around the connecting shaft.

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

[0039] In a specific embodiment of the present invention, Figure 1 , 6 As shown, the edge of the top cover 6 is rotatably matched with the cup cover 2 through two symmetrical mounting shafts 20, two opposite pressing parts 21 are arranged on the top surface of the movable edge of the top cover 6, and the bottom of the top cover 6 is provided with multiple adjustment plates 22 and a semi-cylindrical closed cavity 23 matched with the inner wall of the cup cover 2, multiple adjustment plates 22 are arranged in parallel and spaced, and are arranged below the two pressing parts 21 opposite to the semi-cylindrical closed cavity 23, multiple adjustment plates 22 are correspondingly arranged above the valve plate 8, and the lower part of the adjustment plate 22 is provided with a bevel that can fit with the outer side of the valve plate 8. Among them, 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 cover 2 is provided with a mounting column 24 that rotates with the rotating shaft, and the top of the mounting column is an arc groove with an upper opening, and the arc groove rotates with the rotating shaft. The arc groove is a superior arc groove that can accommodate the rotating shaft, and a limit platform is provided at the end of the rotating shaft for limiting the rotating shaft. The top cover with the structure can make the atomizer more coordinated and beautiful. In the specific production, the mounting shaft and the top cover, the mounting column and the cup cover can be integrally injection molded.

[0040] When making specific Figure 8 , 9 As shown, a lever 25 is provided on the inner side of the installation shaft 20, and the upper end of the lever 25 is rotatably connected to the installation shaft 20 through a torsion spring (not shown in the figure), and a convex point 32 is provided on the outer side of the lower end of the lever 25, and a limiting groove 33 that cooperates with the convex point 32 is provided on the inner side of the installation column 24. Among them, an arc groove is provided at the lower end of the limiting groove, and the limiting groove is used to play a role of sliding and limiting when pressing the top cover. With the opening and closing states of the top cover, the convex point will slide to the two ends of the arc groove, and the torsion spring can be used to achieve the reset of the top cover.

[0041] When assembling the cup body and the cup lid, Figure 1 , 7 As shown, the top edge of the cup body 1 is provided with a mounting groove 26, and the mounting groove 26 includes an inclined section and a horizontal section. The outer wall of the cup cover 2 is correspondingly provided with a convex block 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 cooperates with the convex block 27, and the edge of the mounting groove 26 adjacent to the positioning groove is provided with a locking convex point 28 that protrudes upward; the outer wall of the cup cover 2 below the locking convex point 28 is provided with a connecting buckle 29, and the side wall of the cup body 1 is correspondingly provided with a sliding groove (not shown) that cooperates with the connecting buckle 29. When installing the cup cover, tighten the connecting buckle in the clockwise direction of the cup body, and the convex block of the cup cover reaches the locking convex point along the mounting groove and passes over the locking convex point to achieve the locking of the cup cover. At the same time, the outer wall of the inner ring of the cup cover fits with the inner wall of the top opening of the cup body, which can play a sealing role.

[0042] The working principle of the present invention is as follows:

[0043] like Figure 5 As shown, when inhaling, the valve plate 8 is driven by the inhaled airflow of the user, the top cover 6 and the cup cover 2 are sealed, and only the vent hole on the valve plate 8 has a gap in the cup body 1. The outside air 31 passes through the top cover 6 and pushes the one-way valve plate 16 from the vent hole of the V-shaped groove 11 at the lower part of the cup cover 2 to enter the interior of the cup body 1; at the same time, the external airflow squeezes the plane of the valve plate 8, and the valve plate 8 is tightly attached to the inclined surface of the V-shaped groove 11 under the action of gravity and squeezing force, so that the head of the collision plate 10 is vertically downward, and the lower end of the collision plate 10 is The top of the cup core 12 and the cone tip of the air outlet pipe 13 form a narrow space. 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, forming a negative pressure. Under the action of the Venturi principle, the liquid medicine in the medicine storage bin 4 is sucked to the top of the air outlet pipe 13, and hits the head of the collision plate 10 through the cone tip outlet to form micron-sized aerosol particles. The aerosol particles 30 are inhaled by the user under the action of the compressed air and the airflow of the user's inhalation. During the inhalation process, the atomizer emits mist normally.

[0044] On the contrary, if Figure 4 As shown, when exhaling, the exhaled gas enters the cup body 1 through the mist outlet 5, and the airflow exerts force on the valve plate 8 and the one-way valve plate 16 through the air holes on the inclined surface of one side of the V-shaped groove 11. The one-way valve plate 16 blocks the air holes on the valve plate 8, thereby driving the valve plate 8 to swing upward, and at the same time driving the collision 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 pipe 13, and thus atomization cannot be achieved. The airflow is finally discharged upward along the inner cavity of the cup cover 2 through the edge of the top cover 6. During the exhalation process, the atomizer will not emit mist.

[0045] In addition, by pressing the front and rear pressing parts 21 of the top cover 6, when the pressing part 21 is in a horizontal state, the adjustment plate 22 is away from the valve plate 8, and the valve plate 8 can swing normally under the exhalation / inhalation airflow, and then the collision plate 10 deviates from or faces the spray cone tip of the cup core 12, so that the atomizer can switch between non-mist and mist with breathing. Figure 2 As shown, when the front pressing portion 21 of the top cover 6 is pressed, the regulating 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, the present invention can achieve intermittent atomization with the user's breathing, which can effectively save atomized drugs, improve drug utilization, and reduce drug usage. The present invention can control the atomization of the atomizer according to actual conditions, so that intermittent atomization and continuous atomization can be achieved, so that the atomization treatment can be better coordinated with the patient's breathing, and the effectiveness and adaptability of the atomization treatment can be improved.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
