Description

Technical Field

[0001] The invention belongs to the technical field of atomization equipment, and in particular relates to a breath-following 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 confrontation, 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 nebulizer with intermittent spraying with breathing is designed and developed.

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In the following detailed description of the present invention, some specific details are described in detail. However, for the parts not described in detail, those skilled in the art can also fully understand the present invention.

[0034] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn to scale.

[0035] At the same time, unless the context clearly requires otherwise, the words "include", "comprises" and similar words throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, a breath-following nebulizer provided by an embodiment of the present invention comprises a cup body 1 and a cup cover 2, wherein the upper side wall of the cup body 1 is provided with a mist outlet 3, and the lower part is provided with a medicine storage bin 4 for containing liquid medicine, and the middle part of the cup body is provided with an atomizing mechanism, and the bottom of the atomizing mechanism can be connected to an external air source, and is used to atomize the liquid medicine in the medicine storage bin 4 and discharge it from the mist outlet 3; the bottom of the cup cover 2 is provided with a driving airway 5 that can communicate with the outside world, and the driving airway 5 is arranged in the cup body 1, and its bottom is connected to the cup core 6 of the atomizing mechanism, and the driving airway 5 is provided with an adjustment mechanism that cooperates with the side spray window 13 of the top spray section 60 of the cup core 6, and the adjustment mechanism is used to make the nebulizer not emit mist when exhaling and emit mist when inhaling. The present invention can realize intermittent spraying, improve the use effect of atomized medicine, and avoid medicine waste.

[0037] In a specific embodiment of the present invention, the atomization mechanism includes an air inlet pipe 19, a collision plate 20 and a conical cup core 6, the lower end of the air inlet pipe 19 extends to the bottom of the cup body 1, the upper end of the air inlet pipe 19 is conical and extends to the top of the inner cavity of the cup core 6, an interlayer is provided between the cup core 6 and the air inlet pipe 19, the cup core 6 and the top of the air inlet pipe 19 are provided with outlets, and a gap is provided between the bottom of the cup core 6 and the bottom of the medicine storage bin 4 for the passage of the medicine liquid; the collision plate 20 is arranged at the bottom of the driving airway 5 and corresponds to the lower end of the rotating shaft 9 of the adjusting mechanism, the lower end of the collision plate 20 can be directly opposite to the top outlet of the cup core 6, and a spray window 13 is provided on the top side of the cup core 6. The atomization mechanism uses the Venturi principle. The external driving air source enters the top cone through the air inlet pipe. When it passes through the small hole outlet at the top of the cone, the airflow is accelerated. The airflow at the cone tip is accelerated to form a negative pressure at the top of the interlayer. A pressure difference is formed between the top and bottom of the cone tip. The liquid in the medicine storage bin is sent to the top of the cone tip under the action of the pressure difference. At the same time, it hits the vertical impact plate above under the influence of the airflow at the cone tip, and hits into tiny aerosol particles, which are ejected from the mist outlet driven by the airflow in the cup. By setting a driving airway and an adjustment mechanism above the atomization mechanism, the atomizer can be made to not emit mist when exhaling and emit mist when inhaling.

[0038] During specific production, the striker 20 can be fixed to the inner wall of the bottom of the driving airway 5 by a horizontal connecting rod. At the same time, the top of the striker is a hemispherical protrusion, and the lower end of the rotating shaft is provided with a hemispherical groove that matches the hemispherical protrusion, and the top of the hemispherical groove is a plane. After the striker is assembled with the rotating shaft, the hemispherical protrusion and the top of the hemispherical groove can be in point contact, and during the rotation of the rotating shaft, the striker can achieve resistance-free rotation.

[0039] As a preferred structure, Figure 3As shown, the driving airway 5 is a tubular shell, the upper end of the driving airway 5 transitions with the side wall of the cup cover 2 in an arc, a pair of hanging arms 7 are provided on the conical outer wall of the cup core 6, and the upper ends of the hanging arms 7 are detachably connected to the bottom of the driving airway 5. Among them, symmetrical lugs 8 are provided on the outer wall of the bottom of the driving airway 5, and the upper ends of the hanging arms 7 are connected to the lugs 8 by snap-fitting. The use of this structure can connect the cup cover, driving airway, adjustment mechanism and cup core together, ensuring that the product is structurally complete and reliable when leaving the factory.

[0040] In a specific embodiment of the present invention, Figure 3 , 4 As shown, the adjustment mechanism includes a rotating shaft 9, an adjusting knob 10 and a breathable top cover 11, the top cover 11 is detachably connected (clamped) to the cup cover 2, the top cover 11 is connected to the adjusting knob 10, and a limiting structure is provided between the adjusting knob 10 and the top of the rotating shaft 9, which is used to limit the rotation amplitude of the rotating shaft 9; a fan blade 12 is provided in the middle of the rotating shaft 9, and a flow limiting structure that can cooperate with the spray window 13 of the spray section 60 is provided at the lower end of the rotating shaft 9, which is used to prevent the atomizer from emitting mist during exhalation and emitting mist during inhalation; the collision plate 20 is arranged above the flow limiting structure, and the flow limiting structure is arranged above the lower end of the suspension arm 7. The flow limiting structure includes a breathable cap 14 and a connecting arm 15. The breathable cap 14 is a truncated cone-shaped tube that passes through from top to bottom. The side wall of the breathable cap 14 is provided with a side window 16 that can correspond to the spray window 13 on the side wall of the spray section 60. The breathable cap 14 can be mounted on the top of the truncated cone-shaped spray section 60. The connecting arm 15 is two and symmetrically arranged at the bottom of the rotating shaft 9. The short side end of the connecting arm 15 is connected to the rotating shaft 9, and the long side end of the connecting arm 15 is connected to the outer wall of the breathable cap 14. The working principle of the above-mentioned adjustment mechanism is as follows:

[0041] The sealing property of the top of the cup core is changed by opening a spray window on the side wall of the spray section, and a side window is opened on the side wall of the breathable cap to drive the fan blades in the airway to rotate under the drive of the exhalation / inhalation airflow, so as to achieve the staggered closure or aligned opening of the side window and the spray window, such as Figure 5-8As shown. When the side window of the air cap and the spray window on the spray section are misaligned and closed, the driving airflow at the bottom of the atomizer cup flows out from the spray window, and the bottom airflow rushes directly to the cone tip, hits the impact plate, forms negative pressure around the cone hole, and carries the liquid medicine at the bottom of the cup body to the cone tip, which impacts to form aerosol particles. When exhaling, the airflow in the airway drives the fan blades to rotate counterclockwise, and the side window of the air cap is aligned with the spray window of the spray section, blowing up the driving airflow in the cup body and blowing it out from the side of the open channel. The airflow at the top of the cone tip of the cup core and the impact plate cannot form a high-speed airflow, and the top area of ​​the cone tip cannot form a negative pressure area. The liquid at the bottom of the medicine storage bin cannot be attracted to the cone tip by the negative pressure and collide with the impact plate. No aerosol particles are generated in the atomizer cup, and the atomizer cup does not emit fog.

[0042] During the specific production, the side window on the air cap 14 and the spray window 13 on the spray section 60 are both rectangular openings. The bottom of the spray section of the cup core 6 is provided with a step that matches the bottom of the air cap 14, so that the air cap can be positioned.

[0043] In a specific embodiment of the present invention, Figure 9-11 As shown, the limiting structure includes a semi-cylinder 90 at the top of the rotating shaft 9 and a positioning protrusion 17 on the inner wall of the adjusting knob 10, wherein the positioning protrusion 17 occupies one-fourth of the circumferential space of the inner hole of the adjusting knob 10, and the semi-cylinder 90 is arranged in a three-quarter cavity of the inner hole of the adjusting knob 10, and the positioning protrusion 17 in the adjusting knob 10 can rotate 90 degrees relative to the rotating shaft 9. Among them, the outer wall of the semi-cylinder 90 of the rotating shaft 9 and the inner hole of the adjusting knob 10 are clearance-matched, and the top of the semi-cylinder 90 is a spherical surface, so that the semi-cylinder can realize a fixed angle rotation in the inner hole of the adjusting knob. The fan blades on the rotating shaft rotate under the drive of the respiratory airflow, thereby driving the rotating shaft to realize a fixed angle rotation.

[0044] Further optimize the above structure, such as Fig. 9 As shown, a triangular indicator mark 18 is provided on the inner ring top surface of the top cover 11, which is used to mark the position of the positioning convex point 17. When the positioning convex point 17 of the adjusting knob 10 is rotated to align with the indicator mark 18, the rotating shaft 9 is locked in the counterclockwise direction, the fan blade cannot rotate, and the atomizing cup is in a continuous misting state; when the positioning convex point 17 at the bottom of the adjusting knob 10 is rotated to 90 degrees counterclockwise with the indicator mark 18 on the top cover 11, the rotating shaft 9 can rotate counterclockwise with the user's exhaled airflow, the upper window 16 of the air permeable cap 14 is aligned with the spray window 13 on the cup core 6, the spray channel is opened, the bottom driving airflow is depressurized from the window, and a high-speed airflow cannot be formed between the top of the cone tip and the collision plate, and then a negative pressure cannot be formed to attract the liquid at the bottom of the cup body upward, the Venturi effect cannot be achieved, and no mist is produced during exhalation.

[0045] like Figure 1 , 3As shown, the middle outer diameter of the adjusting knob 10 matches the inner diameter of the inner ring in the middle of the top cover 11, the inner ring is connected to the outer ring of the top cover 11 through connecting ribs, the bottom convex edge of the adjusting knob 10 is arranged below the inner ring, the upper part of the adjusting knob 10 extends to the top of the inner ring, and the outer wall thereof is provided with anti-slip grooves to facilitate adjustment of the position of the adjusting knob.

[0046] During specific production, a mounting groove 21 is provided on the top edge of the cup body 1, and a convex block 22 capable of sliding along the mounting groove 21 is provided on the outer wall of the cup cover 2. A positioning groove cooperating with the convex block 22 is provided at the root of the mounting groove 21, and a locking convex point 23 protruding upward is provided on the edge of the mounting groove 21 adjacent to the positioning groove; a connecting buckle 24 is provided on the outer wall of the cup cover 2 below the locking convex point 23, and a sliding groove (not shown) cooperating with the connecting buckle 24 is provided on the inner wall of the cup body 1. During assembly, the connecting buckle on the cup cover is tightened along 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.

[0047] Install the above-mentioned adjustment mechanism on the cup core, install the adjustment knob 10 on the top, and install the top cover 11 on the adjustment knob 10 from bottom to top. The buckle ribs in the outer circle of the top cover 11 are buckled and installed with the grooves corresponding to the cup cover 2. After installation, the cup body 1, cup cover 2, cup core 6, adjustment mechanism, adjustment knob 10 and top cover 11 form an assembled whole. The rotation of the rotating shaft 9 can be controlled by the adjustment knob 10. After the cup body, cup cover and top cover are installed, only the mist outlet and the top of the driving airway of the atomizer are connected to the outside world, and the other parts are in a sealed state. The specific working process is as follows:

[0048] When in use, the airflow can only enter / exit the atomizer cup through the middle air supply; the outer diameter of the fan blade is consistent with the inner diameter of the driving airway, and the airflow can only flow between the fan blades, thereby ensuring that the airflow can drive the fan blades and drive the rotation of the fan blades and the rotating shaft. The sealing of the top of the cup core cone tip is changed by the spray window set in the spray section of the cup core and the side window arranged in a staggered manner on the umbrella cap. Driven by the exhaled / inhaled airflow, the fan blades in the driving airway drive the rotating shaft to rotate, so that the two windows are closed or aligned with the openings. When the spray window and the side window are staggered and closed, the bottom of the atomizer cup drives the airflow to flow out of the window, and the bottom airflow rushes directly to the cone tip, hits the collision plate, and forms a negative pressure around the cone hole, entraining the liquid at the bottom of the cup body to the cone tip, and hits to form aerosol particles. When exhaling, the airflow drives the fan blades to rotate counterclockwise, and the side window of the umbrella cap is aligned with the window of the cup core, blowing up the driving airflow in the atomizer cup and blowing it out from the side of the open window. The airflow at the top of the cone tip of the cup core and the impact plate cannot form a high-speed airflow, and the negative pressure area cannot be formed in the top area of ​​the cone tip. The liquid at the bottom of the atomizer cup cannot be attracted to the cone tip by the negative pressure and collide with the impact plate. No aerosol particles are generated in the atomizer cup, and no mist is emitted from the atomizer cup.

[0049] In summary, the nebulizer provided by the present invention is connected to the outside world only through the mist outlet and the top of the driving airway. The rotation of the rotating shaft is controlled by the adjusting knob. As the rotating shaft rotates, the conditions for the occurrence of Venturi can be changed, so that the nebulizer cup does not emit mist when exhaling, and emits mist when the patient inhales. When the rotating shaft is not locked by the adjusting knob, under the drive of the user's exhalation / inhalation airflow, the airflow drives the fan blades to rotate through the driving airway, thereby realizing the opening / closing of the upper window of the air permeable cap and the spray window on the cup core, and the occurrence / non-occurrence of the Venturi effect, so that the nebulizer does not emit mist when exhaling, and emits mist when the patient exhales, which greatly improves the utilization rate of the drug and greatly reduces the amount of drug used. The present invention can realize intermittent atomization, which can effectively save atomized drugs, improve the utilization rate of drugs, and reduce the amount of drugs used; at the same time, the atomization treatment and the patient's breathing process are better coordinated, and the adaptability of the atomization treatment is improved.
