Description

Technical Field

[0001] The invention relates to the technical field of medical accessories, and in particular to an atomizer cup and an atomizer with adjustable mist output. Background Art

[0002] Nebulizer therapy is a method of turning drugs into mist with the help of a nebulizer, which then enters the patient's diseased part through the respiratory tract, allowing the drugs to be directly absorbed by the patient's diseased part, thereby achieving the purpose of treating respiratory diseases.

[0003] At present, the nebulizer device commonly used in medical institutions is a compressed nebulizer device, which includes a nebulizer cup. Its working method is to pour an appropriate amount of liquid medicine into the nebulizer cup, and pass compressed air into the nebulizer cup through the air inlet at the bottom of the nebulizer cup. The compressed air acts on the liquid medicine to atomize the liquid medicine, which is then sprayed out from the mist outlet holes on the side wall of the nebulizer cup for inhalation by the patient.

[0004] However, in actual use, the inventors found that the current atomizer cup still has some shortcomings, specifically: During the use of the current nebulizer cup, the patient's exhaled gas needs to enter the cavity of the nebulizer cup and then be discharged to the external environment through the auxiliary gas outlet. In this way, after the exhaled gas enters the cavity of the nebulizer cup, it is easy to collide with the compressed air sprayed from the air inlet port, weakening the force of the compressed air impacting the atomizing beam, which will cause the particle size of the atomized drug solution to increase. On the other hand, the exhaled airflow flows back into the nebulizer cup, which will also cause the fog particles dispersed in the cavity of the nebulizer cup to gather, and then the fog particles are easy to fuse, further causing the particle size of the fog particles to increase. The particle size of the atomized drug fog particles is too large, which is easy to deposit in the human respiratory tract during inhalation, resulting in a reduction in the total amount of drugs reaching deep into the lungs, affecting the treatment effect.

[0005] Therefore, in aerosol therapy, how to prevent the exhaled gas from flowing back into the cavity of the aerosol cup is a technical problem that needs to be solved urgently in the prior art. Summary of the invention

[0006] The purpose of the present invention is to provide an atomizer cup and an atomizer with adjustable mist output in view of the problem of how to prevent the exhaled gas from flowing back into the cavity of the atomizer cup in the prior art.

[0007] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions: An atomizing cup with adjustable fog output includes a cup body and an atomizing cup core. An accommodation cavity is provided inside the cup body. An air inlet channel is provided at the bottom of the cup body, and the central axis of the air inlet channel coincides with the central axis of the cup body. The air inlet channel includes a joint section and an air delivery section. The joint section is provided outside the cup body, and the air delivery section is provided inside the accommodation cavity of the cup body. The cross-sectional shape of the air delivery section is set as a frustum structure. A sleeve is further provided at the bottom of the accommodation cavity of the cup body. The cross-sectional shape of the sleeve matches the cross-sectional shape of the air delivery section. The sleeve covers the outside of the air delivery section, and the end of the sleeve extends beyond the end of the air delivery section. A liquid suction groove is further provided on the inner wall of the sleeve. The length of the liquid suction groove matches the length of the sleeve. A liquid inlet is further provided at the bottom of the sleeve. The liquid inlet is used to communicate the liquid suction groove with the accommodation cavity of the cup body. The atomizing cup core is detachably provided inside the accommodation cavity of the cup body and is used for secondary fragmentation of the atomized liquid medicine. A fog suction tube is further provided on the cup body. The fog suction tube includes a main tube section and a mouthpiece section. The main tube section communicates with the accommodation cavity of the cup body. The mouthpiece section includes an inner tube and an outer tube sleeved outside it. The central axes of the inner tube and the outer tube coincide. The cross-sectional size of the inner tube matches the cross-sectional size of the main tube section. The inner tube is spaced from the main tube section. The outer tube is connected to the main tube section. An exhaust gas channel is provided between the outer tube and the inner tube and between the outer tube and the main tube section. A first valve plate is provided at the end of the inner tube away from the main tube section. A second valve plate is provided at the position of the main tube section corresponding to the end of the outer tube. The first valve plate is used to control the opening or closing of the flow channel of the inner tube, and the second valve plate is used to control the opening or closing of the exhaust gas channel. When a negative pressure environment is formed inside the mouthpiece section, the flow channel of the inner tube opens and the exhaust gas channel closes. When a positive pressure environment is formed inside the mouthpiece section, the flow channel of the inner tube closes and the exhaust gas channel opens.

[0008] Preferably, the fog suction tube is inclined and provided on the side surface of the cup body.

[0009] Preferably, when the exhaust gas channel is in an open state, an obtuse angle is formed between the central axis of the second valve plate and the central axis of the exhaust gas channel. A vibration plate is further provided at the end of the outer tube on one side of the main tube section. The vibration plate has a first state and a second state. In the first state, the central axis of the vibration plate is parallel to the central axis of the main tube section. In the second state, the distance between the end of the vibration plate and the main tube section increases, and an acute angle is formed between the central axis of the vibration plate and the central axis of the main tube section. When the air exhaled by the human body flows out of the exhaust gas channel, the vibration plate can continuously switch between the first state and the second state under the action of turbulent flow.

[0010] Preferably, the central axis of the atomizing cup core coincides with the central axis of the air intake passage. The atomizing cup core includes an air outlet passage, a screening ring, and an atomizing cross beam. The air outlet passage is used to connect the accommodating cavity of the cup body with the external environment. The screening ring is arranged at one end of the air outlet passage facing the air intake passage. The end of the screening ring is an open structure. The inner diameter of the screening ring is larger than the inner diameter of the air outlet passage. The end of the sleeve extends into the inside of the screening ring. The atomizing cross beam is arranged in the screening ring, and there is a gap between the atomizing cross beam and the sleeve.

[0011] Preferably, the atomizing cross beam includes a main beam body and a movable beam body. The main beam body is connected to the inner wall of the screening ring. A slideway is arranged inside the main beam body, and a slide bar is arranged in the slideway. The slide bar can slide in the slideway, and the length of the slide bar is greater than the height of the main beam body. The movable beam body is connected to the end of the slide bar facing the air intake passage. First wing plates are also arranged on the left and right sides of the main beam body, and the first wing plates are flush with the top of the main beam body. A second wing plate is also arranged at the end of the slide bar away from the air intake passage. An airbag is arranged between the first wing plate and the second wing plate. An air charging pipe communicating with the airbag is also arranged on the second wing plate. The end of the air charging pipe extends into the inside of the mist suction pipe, and the end of the air charging pipe extends beyond the first valve plate. When air is filled into the airbag through the air charging pipe to make it in an inflated state, the movable beam body abuts against the bottom of the main beam body. When the air in the airbag is discharged through the air charging pipe to make it in a deflated state, a gap is formed between the movable beam body and the main beam body.

[0012] Preferably, the end of the air charging pipe is arranged in a flared structure.

[0013] Preferably, a medicine pool is arranged at the top of the cup body. The medicine pool is used to store atomizing liquid medicine, and the medicine pool is communicated with the air outlet passage. A piston and a piston rod are also arranged inside the air outlet passage. The piston rod is used to control the up and down movement of the piston in the air outlet passage. An auxiliary air passage is also arranged inside the piston rod and the piston. An out medicine port communicating with the accommodating cavity of the cup body is arranged on the inner wall of the air outlet passage. The opening or closing of the out medicine port can be controlled by moving the piston.

[0014] Preferably, a limiting ring plate is arranged at the top of the air outlet passage. The limiting ring plate is used to prevent the piston from sliding out of the air outlet passage.

[0015] Preferably, a regulating valve is also arranged at the top of the piston rod. The regulating valve is used to change the cross-sectional area of the auxiliary air passage.

[0016] Preferably, a handle is also arranged on the cup body. The handle is used for the user to hold.

[0017] An atomizer includes a high-pressure air pump and also includes the above-mentioned atomization cup.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. For the atomization cup with adjustable fog output amount described in the present invention, the first valve plate is arranged at the end of the inner tube away from the main tube section, and the second valve plate is arranged at the position corresponding to the end of the outer tube on the main tube section. When inhaling, the first valve plate controls the opening of the flow channel of the inner tube, and the second valve plate controls the closing of the exhaust gas channel, so as to avoid the dilution of the drug concentration by the external air entering the mouthpiece section through the exhaust gas channel; when exhaling, the first valve plate controls the closing of the flow channel of the inner tube, and the second valve plate controls the opening of the exhaust gas channel, so that the gas exhaled by the human body can be discharged to the external environment through the exhaust gas channel, avoiding the exhaled gas entering the cup body and affecting the particle size of the fog particles, increasing the total amount of drugs entering the deep part of the lungs in a single breath, and improving the treatment effect; further, during the process of the gas exhaled by the human body being discharged to the external environment through the exhaust gas channel, a pressure difference will be formed inside and outside the main tube section. Under the action of the pressure difference, the air in the accommodation cavity of the cup body can be driven to generate a certain fluidity, so as to avoid excessive aggregation of the atomized fog particles during exhalation, resulting in the fusion of the fog particles; and, during the air flow process, the large-particle-size fog particles that are not fully atomized in the middle part of the cup body can be driven out to the external environment, so as to ensure that the finally output fog particle size is more uniform and finer, significantly improving the deposition efficiency of the drug in the alveolar region and achieving a better treatment effect; 2. In the atomizing cup with adjustable fog output volume according to the present invention, the movable beam body is arranged to cooperate with the main beam body. During inhalation, the distance between the bottom of the movable beam body and the top of the sleeve decreases, and the sealed space formed between the upper part of the sleeve opening and the movable beam body decreases, so that the high-pressure air flow is not easily affected by the inhaled air flow and escapes. In this way, the negative pressure suction force generated can become larger, and then the compressed air flow collides more violently with the movable beam body, so that the initially atomized medicine mist can be broken into finer mist particles. Moreover, after the compressed air flow impacts the atomizing cross beam and turns into a radial direction, the mist particles can obtain a faster radial movement speed, and the distance of the radial movement of the mist particles per unit time is larger. Therefore, the probability of the mist particles colliding with the screening ring increases, the elimination rate of large-particle-size mist particles is improved, and the particle size of the finally output mist particles is ensured to be more uniform and finer. On the other hand, the first wing plate and the second wing plate arranged can also guide the external air to flow towards the inner wall of the screening ring, so that the air flow speed in the area near the inner wall of the screening ring is greater than that in the central area. In this way, a low-pressure area will be formed in the area of the inner wall of the screening ring, attracting the mist particles to move towards the inner wall of the screening ring, further improving the elimination rate of large-particle-size mist particles and ensuring that the particle size of the finally output mist particles is more uniform and finer.

[0019] On the other hand, during inhalation, the distance between the bottom of the movable beam body and the top of the sleeve decreases. After generating a greater negative pressure suction force, the atomization rate of the liquid medicine per unit time can also be increased, ensuring the concentration of the inhaled medicine mist, thereby further improving the treatment effect. During exhalation, the air flow speed in the cup body is relatively low. At this time, the bottom of the movable beam body moves away from the top of the sleeve, and the sealed space formed between the upper part of the sleeve opening and the movable beam body increases, making it easier for the high-pressure air flow to escape and the negative pressure suction force to become smaller. In this way, the atomization efficiency of the liquid medicine per unit time decreases, avoiding excessive aggregation of the atomized mist particles during exhalation, resulting in the fusion of the mist particles to generate large-particle-size mist particles, and further ensuring that the particle size of the output mist particles is more uniform and finer. 3. An atomizing cup with adjustable fog output according to the present invention. When the exhaust gas passage is in an open state, an obtuse angle is formed between the central axis of the second raft and the central axis of the exhaust gas passage; a vibrating plate is further provided at the end of the outer tube on the side of the main pipe section. The vibrating plate has a first state and a second state. In the first state, the central axis of the vibrating plate is parallel to the central axis of the main pipe section; in the second state, the spacing distance between the end of the vibrating plate and the main pipe section increases, and an acute angle is formed between the central axis of the vibrating plate and the central axis of the main pipe section; when the air exhaled by the human body flows out of the exhaust gas passage, the vibrating plate can continuously switch between the first state and the second state under the action of turbulent flow. With this structural arrangement, during the process of the exhaled gas being discharged from the exhaust gas passage to the external environment, due to the blockage of the second raft, turbulent flow will be formed at the opening of the exhaust gas passage. Under the push of the turbulent flow, the vibrating plate can continuously switch between the first state and the second state, causing the fog suction tube to vibrate. In this way, the water droplets adhering to the inner wall of the fog suction tube can be further shed, reducing the risk of water droplets being accidentally inhaled into the trachea during use.

An accommodation cavity is provided inside the cup body 1. An air inlet channel 3 is provided at the bottom of the cup body 1. The central axis of the air inlet channel 3 coincides with the central axis of the cup body 1. The air inlet channel 3 includes a connector section 4 and an air delivery section 5.

The length of the liquid suction groove 7 matches the length of the sleeve 6. A liquid inlet 8 is further provided at the bottom of the sleeve 6. The liquid inlet 8 is used to communicate the liquid suction groove 7 with the accommodation cavity of the cup body 1. The atomizing cup core 2 is detachably provided in the accommodation cavity of the cup body 1. The atomizing cup core 2 is used for secondary fragmentation of the atomized liquid medicine. A fog suction pipe 9 is further provided on the cup body 1. The fog suction pipe 9 includes a main pipe section 10 and a mouthpiece section 11. The main pipe section 10 is communicated with the accommodation cavity of the cup body 1. The mouthpiece section 11 includes an inner pipe 12 and an outer pipe 13 sleeved outside it. The central axes of the inner pipe 12 and the outer pipe 13 coincide. The cross-sectional size of the inner pipe 12 matches the cross-sectional size of the main pipe section 10. The inner pipe 12 and the main pipe section 10 are spaced apart. The outer pipe 13 is connected to the main pipe section 10. An exhaust gas channel 14 is provided between the outer pipe 13 and the inner pipe 12, and between the outer pipe 13 and the main pipe section 10. A first valve plate 15 is provided at the end of the inner pipe 12 away from the main pipe section 10. A second valve plate 16 is provided at the position of the main pipe section 10 corresponding to the end of the outer pipe 13. The first valve plate 15 is used to control the opening or closing of the flow channel of the inner pipe 12. The second valve plate 16 is used to control the opening or closing of the exhaust gas channel 14. When a negative pressure environment is formed in the mouthpiece section 11, the flow channel of the inner pipe 12 is opened, and the exhaust gas channel 14 is closed. When a positive pressure environment is formed in the mouthpiece section 11, the flow channel of the inner pipe 12 is closed, and the exhaust gas channel 14 is opened.

[0028] Adopt an atomizing cup with adjustable fog output amount according to the present invention. A first valve plate 15 is arranged at the end of the inner tube 12 far from the main pipe section 10, and a second valve plate 16 is arranged on the main pipe section 10 at a position corresponding to the end of the outer tube 13. During inhalation, the first valve plate 15 controls the opening of the flow channel of the inner tube 12, and the second valve plate 16 controls the closing of the waste gas channel 14, so as to avoid external air entering the mouthpiece section 11 through the waste gas channel 14 and diluting the concentration of the drug; during exhalation, the first valve plate 15 controls the closing of the flow channel of the inner tube 12, and the second valve plate 16 controls the opening of the waste gas channel 14, so that the gas exhaled by the human body can be discharged to the external environment through the waste gas channel 14, avoiding the exhaled gas entering the cup body 1 and affecting the particle size of the fog particles, increasing the total amount of drug entering the deep part of the lungs in a single breath, and improving the treatment effect; further, during the process of the gas exhaled by the human body being discharged to the external environment through the waste gas channel 14, a pressure difference will be formed inside and outside the main pipe section 10. Under the action of the pressure difference, the air in the accommodation cavity of the cup body 1 can be driven to generate a certain fluidity, so as to avoid excessive aggregation of the atomized fog particles during exhalation, resulting in the fusion of the fog particles; and, during the process of air flow, the large-particle-size fog particles that are not fully atomized in the middle part of the cup body 1 can be driven to be discharged to the external environment, so as to ensure that the finally output fog particles are more uniform and finer in particle size, significantly improving the deposition efficiency of the drug in the alveolar region and achieving a better treatment effect.

[0029] Specifically, in this embodiment, the bottom of the cup body 1 is inclined towards the air delivery section 5, so that a liquid storage pool structure for storing atomized liquid medicine can be formed in the bottom area of the cup body 1; in the use of the present invention, first pour the atomized liquid medicine into the cup body 1, and then install the atomizing cup core 2; after introducing compressed gas into the air intake channel 3, according to the Venturi principle, under the action of negative pressure suction, the liquid medicine in the liquid storage pool is sucked to the top of the air delivery section 5 through the liquid suction groove 7. Under the action of the compressed gas, the liquid medicine is atomized into medicine mist. Further, under the carrying of the air flow, the medicine mist collides violently with the bottom of the atomizing cup core 2, causing it to break into finer fog particles. After the air flow impacts the bottom of the atomizing cup core 2, it will turn radially and carry the fog particles to radially diffuse and fill the accommodation cavity inside the cup body 1.

[0030] It should be noted in this embodiment that during the inhalation process, the air inside the cup body 1 will rapidly flow towards the direction of the mist suction tube 9. During this process, a part of the initially atomized medicine mist will be affected by the inhaled air flow, resulting in its inability to collide with the bottom of the atomization cup core 2, and thus large-sized mist particles are generated. During the inhalation process, a part of the large-sized mist particles will be inhaled by the human body; while another part will stay inside the cup body 1 with the end of the inhalation action. In this embodiment, by using the pressure difference formed by the exhaled gas of the human body passing through the waste gas channel 14, the air in the accommodation cavity of the cup body 1 is driven to have a certain fluidity. Furthermore, some of the large-sized mist particles that are not fully atomized in the cup body 1 can be driven out to the external environment, thereby ensuring that the finally output mist particle size is more uniform and finer, significantly improving the deposition efficiency of the drug in the alveolar region, and achieving a better therapeutic effect.

[0031] As a preferred implementation manner, on the basis of the above manner, further, the mist suction tube 9 is inclined and arranged on the side surface of the cup body 1. With this structural arrangement, the smoothness of the air flowing from the cup body 1 into the mist suction tube 9 can be improved; at the same time, with this structural arrangement, the adhesion of water droplets to the inner wall of the mist suction tube 9 can also be effectively inhibited, thereby reducing the risk of water droplets being accidentally inhaled into the trachea during use.

[0032] Embodiment Two: Refer to Figure 1 and Figure 4 As shown, as a preferred implementation manner, on the basis of the above manner, further, when the waste gas channel 14 is in an open state, an obtuse angle is formed between the central axis of the second raft 16 and the central axis of the waste gas channel 14; a vibration plate 17 is also provided at the end of the outer tube 13 on one side of the main pipe section 10. The vibration plate 17 has a first state and a second state. In the first state, the central axis of the vibration plate 17 is parallel to the central axis of the main pipe section 10; in the second state, the distance between the end of the vibration plate 17 and the main pipe section 10 increases, and an acute angle is formed between the central axis of the vibration plate 17 and the central axis of the main pipe section 10; when the exhaled air of the human body flows out of the waste gas channel 14, the vibration plate 17 can continuously switch between the first state and the second state under the action of turbulent flow.

[0033] Specifically, in this embodiment, during the process of the exhaled gas being discharged from the waste gas channel 14 to the external environment, due to the blockage of the second raft 16, turbulent flow will be formed at the opening part of the waste gas channel 14. Under the push of the turbulent flow, the vibration plate 17 can continuously switch between the first state and the second state, causing the mist suction tube 9 to vibrate. In this way, the water droplets adhering to the inner wall of the mist suction tube 9 can be further detached, reducing the risk of water droplets being accidentally inhaled into the trachea during use.

[0034] Embodiment Three: Refer toFigure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , as a preferred embodiment, on the basis of the above-described manner, further, the central axis of the atomization cup core 2 coincides with the central axis of the intake passage 3. The atomization cup core 2 includes an air outlet passage 18, a screening ring 19, and an atomization cross beam 20. The air outlet passage 18 is used to communicate the accommodation cavity of the cup body 1 with the external environment. The screening ring 19 is disposed at one end of the air outlet passage 18 facing the intake passage 3. The end of the screening ring 19 is an open structure. The inner diameter of the screening ring 19 is larger than the inner diameter of the air outlet passage 18. The end of the sleeve 6 extends into the interior of the screening ring 19. The atomization cross beam 20 is disposed within the screening ring 19, and there is a gap between the atomization cross beam 20 and the sleeve 6.

[0035] Specifically, in this embodiment, when the liquid medicine is initially atomized and the compressed air flow carries the mist particles and impacts on the atomization cross beam 20, intense collisions will occur to generate finer mist particles. And after the compressed air flow impacts on the atomization cross beam 20, it will change to a radial direction and carry the mist particles to diffuse radially. During this process, the micron-sized mist particles will diffuse in the accommodation cavity of the cup body 1 due to the complex flow field conditions, while the millimeter-sized mist particles will directly impact on the screening ring 19 due to inertia and flow back to the bottom of the cup body 1. In this way, the screening of the mist particles is achieved, thereby ensuring that the finally output mist particle size is more uniform and finer, and improving the effect of inhalation therapy.

[0036] As a preferred embodiment, on the basis of the above-described manner, further, the atomizing cross beam 20 includes a main beam body 21 and a movable beam body 22. The main beam body 21 is connected to the inner wall of the screening ring 19. A slideway 23 is provided inside the main beam body 21. A slide bar 24 is arranged in the slideway 23. The slide bar 24 can slide in the slideway 23, and the length of the slide bar 24 is greater than the height of the main beam body 21. The movable beam body 22 is connected to the end of the slide bar 24 facing the air inlet passage 3. First wing plates 25 are further provided on the left and right sides of the main beam body 21. The first wing plates 25 are arranged flush with the top of the main beam body 21. A second wing plate 26 is further provided at the end of the slide bar 24 away from the air inlet passage 3. An airbag 27 is arranged between the first wing plate 25 and the second wing plate 26. An air charging pipe 28 communicated with the airbag 27 is further provided on the second wing plate 26. The end of the air charging pipe 28 extends into the mist suction pipe 9, and the end of the air charging pipe 28 extends beyond the first valve plate 15. When air is filled into the airbag 27 through the air charging pipe 28 to make it in an inflated state, the movable beam body 22 abuts against the bottom of the main beam body 21. When the air in the airbag 27 is discharged through the air charging pipe 28 to make it in a deflated state, a gap is formed between the movable beam body 22 and the main beam body 21.

[0037] Specifically, in this embodiment, when exhaling, air enters the airbag 27 through the air charging pipe 28. After the airbag 27 expands, it applies a top thrust on the second wing plate 26. The slide bar 24 slides upward along the slideway 23. Finally, the movable beam body 22 abuts against the bottom of the main beam body 21 and stops. When inhaling, the air in the airbag 27 is discharged through the air charging pipe 28. During the deflation process of the airbag 27, it applies a pulling force on the second wing plate 26. The slide bar 24 slides downward along the slideway 23, and a gap is formed between the movable beam body 22 and the main beam body 21.

[0038] In this embodiment, it is considered that during inhalation, the airflow in the cup body 1 will flow rapidly, and a part of the initially atomized medicine mist will be affected by the inhaled airflow, resulting in its inability to collide with the atomization cross beam 20, forming large-sized mist particles that cannot be inhaled deep into the lungs, affecting the deposition efficiency of the medicine in the alveolar region and reducing the treatment effect. Based on this, in this embodiment, the movable beam body 22 is arranged to cooperate with the main beam body 21. During inhalation, the distance between the bottom of the movable beam body 22 and the top of the sleeve 6 is reduced, and the sealed space formed between the upper opening of the sleeve 6 and the movable beam body 22 is reduced, so that the high-pressure airflow is not easily affected by the inhaled airflow and escapes. In this way, the negative pressure suction generated can become larger, and then the compressed airflow collides more violently with the movable beam body 22, so that the initially atomized medicine mist can be broken into finer mist particles; moreover, after the compressed airflow impacts the atomization cross beam 20 and turns into a radial direction, the mist particles can obtain a faster radial movement speed, and the distance of the mist particles moving radially per unit time is larger. Therefore, the probability of the mist particles colliding with the screening ring 19 increases, the elimination rate of large-sized mist particles is improved, and the particle size of the finally output mist particles is ensured to be more uniform and finer; on the other hand, in this embodiment, the first wing plate 25 and the second wing plate 26 arranged can also guide the external air to flow towards the inner wall of the screening ring 19, so that the air flow speed in the area close to the inner wall of the screening ring 19 is greater than that in the central area. In this way, a low-pressure area will be formed in the inner wall area of the screening ring 19, attracting the mist particles to move towards the inner wall of the screening ring 19, further improving the elimination rate of large-sized mist particles and ensuring that the particle size of the finally output mist particles is more uniform and finer.

[0039] On the other hand, in this embodiment, during inhalation, the distance between the bottom of the movable beam body 22 and the top of the sleeve 6 is reduced. After generating a greater negative pressure suction, the atomization rate of the liquid medicine per unit time can also be increased, ensuring the concentration of the inhaled medicine mist, thereby further improving the treatment effect; during exhalation, the air flow speed in the cup body 1 is relatively low. At this time, the bottom of the movable beam body 22 is far from the top of the sleeve 6, and the sealed space formed between the upper opening of the sleeve 6 and the movable beam body 22 is increased, making it easier for the high-pressure airflow to escape and the negative pressure suction to become smaller. In this way, the atomization efficiency of the liquid medicine per unit time is reduced, avoiding excessive aggregation of the atomized mist particles during exhalation, resulting in the fusion of the mist particles to generate large-sized mist particles, and further ensuring that the particle size of the output mist particles is more uniform and finer.

[0040] As a preferred implementation manner, on the basis of the above manner, further, the end of the air charging pipe 28 is provided with a flared structure. With this structural setting, air can enter the air charging pipe 28 more smoothly, thereby improving the practicality of the present invention in actual use.

[0041] Example Four: Refer toFigure 1 and Figure 5 As shown in Figure 5 , as a preferred embodiment, on the basis of the above method, further, a medicine pool 29 is provided at the top of the cup body 1. The medicine pool 29 is used for storing atomized liquid medicine, and the medicine pool 29 is communicated with the air outlet channel 18. A piston 30 and a piston rod 31 are further arranged inside the air outlet channel 18. The piston rod 31 is used to control the up and down movement of the piston 30 in the air outlet channel 18. An auxiliary air passage is arranged in the piston rod 31 and the piston 30. An medicine outlet 32 communicated with the accommodation cavity of the cup body 1 is arranged on the inner wall of the air outlet channel 18. By moving the piston 30, the opening or closing of the medicine outlet 32 can be controlled.

[0042] Specifically, in actual use of this embodiment, when the piston 30 is moved to the position of the medicine outlet 32 or above the medicine outlet 32, the communication between the medicine pool 29 and the accommodation cavity of the cup body 1 can be cut off; when the piston 30 is moved below the medicine outlet 32, the medicine pool 29 can be communicated with the accommodation cavity of the cup body 1. With this structural arrangement, on the one hand, the convenience of replenishing atomized liquid medicine can be improved; on the other hand, the risk of contamination of the atomizing cup core 2 and the cup body 1 during use is reduced, and the safety of using the atomizing cup is improved.

[0043] As a preferred embodiment, on the basis of the above method, further, a limit ring plate 33 is provided at the top of the air outlet channel 18. The limit ring plate 33 is used to prevent the piston 30 from sliding out of the air outlet channel 18. With this structural arrangement, the practicality of the present invention in actual use is further improved.

[0044] As a preferred embodiment, on the basis of the above method, further, a regulating valve 34 is provided at the top of the piston rod 31. The regulating valve 34 is used to change the cross-sectional area of the auxiliary air passage.

[0045] As a preferred embodiment, on the basis of the above method, further, a handle 35 is provided on the cup body 1. The handle 35 is used for the user to hold. With this structural arrangement, the practicality of the present invention in actual use is further improved.
