Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of atomization equipment, and in particular relates to a breathing-driven 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 mist, 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 system that accompanies respiration was designed and developed.

[0039] As a preferred structure, such as Figure 3 As shown, the driving air passage 5 is a tubular shell, with its upper end transitioning to the side wall of the cup lid 2 via an arc. A pair of lifting arms 7 are provided on the conical outer wall of the cup core 6, with the upper ends of the lifting arms 7 detachably connected to the bottom of the driving air passage 5. Symmetrical lugs 8 are provided on the bottom outer wall of the driving air passage 5, and the upper ends of the lifting arms 7 are connected to the lugs 8 via snap-fit connections.

[0040] In specific embodiments of this utility model, such as Figure 3 , 4 As shown, the adjustment mechanism includes a rotating shaft 9, an adjustment knob 10, and a breathable top cover 11. The top cover 11 is detachably connected (click-fitted) to the cup lid 2. The top cover 11 is connected to the adjustment knob 10. A limiting structure is provided between the adjustment knob 10 and the top of the rotating shaft 9 to limit the rotation amplitude of the rotating shaft 9. A fan blade 12 is provided in the middle of the rotating shaft 9. A flow-limiting structure is provided at the lower end of the rotating shaft 9 to cooperate with the spray window 13 of the spray section 60, so that the atomizer does not produce mist when exhaling and produces mist when inhaling. The impact plate 20 is set above the flow-limiting structure, and the flow-limiting structure is set above the lower end of the boom 7. The flow-limiting structure includes a vent cap 14 and connecting arms 15. The vent cap 14 is a frustoconical tube extending vertically. The side wall of the vent cap 14 has side windows 16 corresponding to the spray windows 13 on the side wall of the spray section 60. The vent cap 14 can be fitted onto the top of the frustoconical spray section 60. Two connecting arms 15 are symmetrically arranged at the bottom of the rotating shaft 9. The short side of each connecting arm 15 is connected to the rotating shaft 9, and the long side is connected to the outer wall of the vent cap 14. The working principle of the above-mentioned adjustment mechanism is as follows:
[0041] By creating a spray window on the side wall of the spray section, the sealing of the top of the cup core is altered. Simultaneously, a side window is created on the side wall of the vent cap. This drives the fan blades within the airway to rotate under the influence of inhalation and exhalation airflow, achieving either staggered closure or aligned opening between the side window and the spray window. Figures 5-8When the side window of the air-permeable cap is misaligned with the spray window on the spray section to be closed, the bottom driving airflow of the atomizing cup flows out of the spray window, and the bottom airflow directly hits the cone tip and impacts the impact plate, forming a negative pressure around the cone hole, which carries the liquid at the bottom of the cup body to the cone tip and impacts to form aerosol particles. When exhaling, the airflow in the driving airway drives the fan blade to rotate counterclockwise, the side window of the air-permeable cap is aligned with the spray window of the spray section, the driving airflow in the cup body is blown out from the opened channel side, the airflow at the top of the cone tip of the cup core cannot form a high-speed airflow with the impact plate, a negative pressure area cannot be formed at the top of the cone tip, and the liquid at the bottom of the medicine storage cannot be attracted to the cone tip by the negative pressure and collide with the impact plate. The atomizing cup does not produce aerosol particles, and the atomizing cup does not spray.
[0042] In specific implementation, the side window on the air-permeable cap 14 and the spray window 13 on the spray section 60 are both rectangular openings. The spray section of the cup core 6 is provided with a step at the bottom matched with the bottom of the air-permeable cap 14, which can position the air-permeable cap.
[0043] In the specific embodiment of the utility model, as shown in the figure, Figures 9-11 The limiting structure includes a semicircular column 90 at the top of the rotating shaft 9 and a positioning protrusion 17 on the inner wall of the adjusting knob 10. The positioning protrusion 17 occupies one fourth of the circumferential space of the inner hole of the adjusting knob 10. The semicircular column 90 is arranged in the three fourths cavity of the inner hole of the adjusting knob 10. The positioning protrusion 17 in the adjusting knob 10 can rotate 90 degrees relative to the rotating shaft 9. The outer wall of the semicircular column 90 of the rotating shaft 9 is gap-fitted with the inner hole of the adjusting knob 10, and the top of the semicircular column 90 is a spherical surface, which can enable the semicircular column to rotate at a fixed angle in the inner hole of the adjusting knob. The fan blade on the rotating shaft rotates under the driving of the respiratory airflow, and then drives the rotating shaft to rotate at a fixed angle.
[0044] The above structure is further optimized, as shown in the figure, Figure 9 The inner ring top surface of the top cover 11 is provided with a triangular indication mark 18, which is used to mark the position of the positioning protrusion 17. When the positioning protrusion 17 of the adjusting knob 10 is rotated to be aligned with the indication 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 protrusion 17 at the bottom of the adjusting knob 10 is rotated to be counterclockwise 90 degrees from the indication mark 18 on the top cover 11, the rotating shaft 9 can rotate counterclockwise with the user's exhalation airflow, the side window 16 on 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 discharged from the window, the top of the cone tip cannot form a high-speed airflow with the impact plate, and then a negative pressure area cannot be formed to attract the liquid at the bottom of the cup body upward, the Venturi effect cannot be realized, and no mist is generated when exhaling.
[0045] As shown in the figure, Figure 1 , 3As shown, the middle outer diameter of the adjusting knob 10 matches the inner diameter of the inner ring of the middle part of the top cover 11, the inner ring is connected with the outer ring of the top cover 11 through the connecting rib, the bottom eaves of the adjusting knob 10 is arranged below the inner ring, and the upper part of the adjusting knob 10 extends above the inner ring and is provided with anti-skid lines on the outer wall, so as to facilitate the adjustment of the position of the adjusting knob.
[0046] In specific manufacturing, the top edge of the cup body 1 is provided with a mounting groove 21, the outer wall of the cup cover 2 is correspondingly provided with a protrusion 22 capable of sliding along the mounting groove 21, the root of the mounting groove 21 is provided with a positioning groove matched with the protrusion 22, and the edge of the mounting groove 21 adjacent to the positioning groove is provided with an upwardly protruding locking protrusion 23; the outer wall of the cup cover 2 below the locking protrusion 23 is provided with a connecting buckle 24, and the inner wall of the cup body 1 is correspondingly provided with a sliding groove (not shown in the figure) matched with the connecting buckle 24. During assembly, the connecting buckle on the cup cover is tightened in the clockwise direction of the cup body, the protrusion of the cup cover reaches the locking protrusion along the mounting groove and passes over the locking protrusion, so as to realize the locking of the cup cover. At the same time, the outer side wall of the inner ring of the cup cover is attached to the inner wall of the top part of the cup body, so as to play a sealing role.
[0047] The adjusting mechanism is installed on the cup core, the adjusting knob 10 is installed on the top, the top cover 11 is installed on the adjusting knob 10 from bottom to top, the buckle rib in the outer circle of the top cover 11 is installed in the corresponding groove buckle of the cup cover 2, and after installation, the cup body 1, the cup cover 2, the cup core 6, the adjusting mechanism, the adjusting knob 10 and the top cover 11 form an assembly whole, and the rotation of the rotating shaft 9 can be controlled through the adjusting knob 10. After the cup body, the cup cover and the top cover are installed, only the mist outlet, the top of the driving air channel and the outside are communicated, and the other parts are in a sealed state. The specific working process is as follows:
[0048] In use, the airflow can only pass through the middle air supplement and enter / exist the atomizing cup; the outer diameter of the fan blade is consistent with the inner diameter of the driving air channel, and the airflow can only flow between the fan blades, so as to ensure that the airflow can drive the fan blade and drive the rotation of the rotating shaft. The sealing property of the top of the cone tip of the cup core is changed through the spray window arranged on the spray section of the cup core and the side window arranged in a staggered manner on the umbrella cap. The fan blade in the driving air channel is driven to rotate by the inhalation / exhalation airflow, so as to drive the rotating shaft to rotate, so that the two windows are closed or aligned with the opening. When the spray window and the side window are closed in a staggered manner, the driving airflow at the bottom of the atomizing cup flows out from the window, the airflow at the bottom directly hits the cone tip, collides with the impact plate, forms a negative pressure around the cone hole, and carries the liquid at the bottom of the cup body to the cone tip to form aerosol particles by collision. When exhaling, the airflow drives the fan blade to rotate counterclockwise, the side window of the umbrella cap is aligned with the window of the cup core, the driving airflow in the atomizing cup is blown, the airflow at the top of the cone tip of the cup core cannot form a high-speed airflow with the impact plate, a negative pressure area cannot be formed at the top of the cone tip, the liquid at the bottom of the atomizing 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 atomizing cup, and no mist is generated from the atomizing cup.
[0049] In summary, the atomizer provided by the utility model only has a mist outlet, a driving air passage top part in communication with the outside, the rotation of the rotating shaft is controlled through the adjusting knob, the rotation of the rotating shaft can change the conditions of the Venturi effect, the atomizing cup is made not to emit mist during exhalation and to emit mist during inhalation of the patient. When the rotating shaft is not locked by the adjusting knob, under the driving of the user's inhalation / exhalation flow, the airflow drives the fan blades to rotate through the driving air passage, thereby realizing the opening / closing of the upper window of the air-permeable cap and the upper spraying window of the cup core, the occurrence / non-occurrence of the Venturi effect, and further making the atomizer not emit mist during exhalation and emit mist during exhalation of the patient, greatly improving the utilization rate of the medicine, and greatly reducing the amount of medicine used. The utility model can realize gap atomization, effectively save atomized medicine, improve the utilization rate of medicine, and reduce the amount of medicine used. Meanwhile, the atomization treatment and the breathing process of the patient are better coordinated, and the adaptability of the atomization treatment is improved.
