Description

Technical Field

[0001] This invention belongs to the technical field of compression atomizers, specifically an ultra-quiet compression atomizer. Background Technology

[0002] A compressor nebulizer is a medical device that uses a high-speed airflow of compressed air to atomize liquid medication into tiny droplets, which are then inhaled by the patient through the mouth and nose to treat respiratory diseases. A handheld compressor nebulizer is a portable medical device that integrates a miniature compressor. It not only possesses the functions of a traditional compressor nebulizer but also offers advantages such as convenience, quiet operation, and portability. In use, the built-in miniature compressor generates compressed air. When the high-speed airflow is ejected from an extremely fine nozzle, a localized negative pressure is created around the nozzle. Under this negative pressure, the liquid medication mixes with the high-speed airflow through a tubing and impacts an overhead obstruction. The high-speed impact breaks the medication into droplets, which are then ejected from the outlet and inhaled by the patient through a mask or mouthpiece. However, existing handheld nebulizers require medication to be injected before use and must be kept upright during use to ensure the medication is submerged in the tubing. For acute respiratory illnesses such as acute asthma, it is difficult for patients to stably inject medication into the nebulizer while they are ill. In addition, patients need to remain upright or sitting during the use of the nebulizer, making it inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide an ultra-quiet compressor atomizer to overcome the inconvenience of using handheld compressor atomizers as mentioned in the background art.

[0004] The technical implementation of the present invention is as follows: an ultra-quiet compression nebulizer includes: a grip body, a mounting shell detachably connected to the grip body, an end cap provided at the end of the mounting shell away from the grip body, a mask insertion hole provided at the end cap, an inner conical shell fixedly connected to the side of the mounting shell near the grip body, the inner conical shell communicating with the grip body, an outer conical shell provided between the end cap and the inner conical shell, a main connecting arm provided on one side of the outer conical shell, a connecting rod provided at the end cap, a partition fixedly connected to the end of the connecting rod near the grip body, the partition, the inner conical shell and the outer conical shell being coaxial, a drug storage stopper embedded at the position corresponding to the end cap and the main connecting arm, a drug storage bladder fixedly connected between the drug storage stopper and the main connecting arm, the drug storage bladder being used to store liquid medicine, a main suction groove provided on the outer periphery of the inner conical shell near the main connecting arm, the main connecting arm being used to transport the liquid medicine in the drug storage bladder to the main suction groove.

[0005] Furthermore, the mounting shell is rotatably and sealingly connected to the end cap, and the inner conical shell is rotatably and sealingly connected to the outer conical shell.

[0006] Furthermore, the end cap is provided with annularly distributed fixing buckles, and the mounting shell is provided with a fixing ring groove near the fixing buckles, through which the fixing buckles limit the end cap.

[0007] Furthermore, a secondary connecting arm is provided on one side of the outer conical shell. The secondary connecting arm is symmetrically distributed with the main connecting arm. A liquid storage plug is embedded in the end cap at the position corresponding to the secondary connecting arm. A liquid storage bladder is fixed between the secondary connecting arm and the liquid storage plug. The liquid storage bladder is used to store cleaning fluid. The secondary connecting arm is connected to the liquid storage bladder and is used to connect with the main suction tank.

[0008] Furthermore, the end cap is fixedly connected to an interceptor shell, the interceptor shell is provided with an exhaust hole, the exhaust hole is offset from the partition in the vertical direction, and the connecting rod passes through the interceptor shell.

[0009] Furthermore, the interceptor shell is provided with a drainage cone on the side near the outer cone shell, the outer cone shell is fixedly connected to the drainage cone, and the outer cone shell is provided with annularly distributed connecting holes near the drainage cone. The inner cone shell is provided with annularly distributed secondary suction grooves that correspond one-to-one with the connecting holes, and the secondary suction grooves are used to communicate with the corresponding connecting holes.

[0010] Furthermore, the number of the connecting holes and the auxiliary liquid suction grooves is not less than four and is an integer multiple of two.

[0011] Furthermore, the connecting rod is threadedly connected to the interceptor shell, the end of the connecting rod away from the gripping body passes through the end cap and is rotatably connected to the end cap, and a knob is fixedly connected to the end of the connecting rod away from the gripping body.

[0012] Furthermore, a positioning post is slidably connected inside the end cap, and a spring is fixed between the positioning post and the end cap. The mounting shell is provided with several positioning grooves at one end near the end cap for limiting the positioning post.

[0013] Furthermore, the end of the positioning post away from the end cap is hemispherical, and the depth of the positioning groove is less than the radius of the hemispherical part of the positioning post.

[0014] The beneficial effects of this invention are as follows: This invention utilizes a drug reservoir to store the medication, allowing for direct use when a patient experiences a sudden acute respiratory illness, eliminating the need for temporary medication injection. Furthermore, the drug reservoir method eliminates the need for the patient to remain upright or seated during nebulization. Combined with the quiet operation of a handheld nebulizer, this improves ease of use and comfort.

[0015] By rotating the end cap, the outer conical shell is rotated, causing the main connecting arm to be misaligned and disconnected from the main liquid suction groove. This prevents the liquid from overflowing from the storage bladder when it is subjected to accidental impact or tilting during the storage process, thus maintaining the cleanliness and sufficiency of the liquid.

[0016] By changing the relative position of the outer and inner conical shells, the connection state between the main connecting arm and the secondary connecting arm and the main suction tank can be switched. After atomization, the cleaning fluid can be atomized to clean the residual drug on the main suction tank, inner conical shell, outer conical shell and partition, without the need for disassembly for cleaning, making cleaning convenient.

[0017] The large-diameter liquid medicine intercepted by the interceptor shell is diverted by the diversion cone, and the large-diameter liquid medicine is collected at the connecting hole. The liquid medicine is re-absorbed by the Venturi effect and mixed with compressed air, thereby improving the utilization rate of the liquid medicine. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0021] Example 1 like Figures 1 to 5As shown, an ultra-quiet compression atomizer includes: a grip body 1, in which a miniature compressor and a battery are installed; a mounting shell 2 is detachably connected to the upper part of the grip body 1, and an end cap 3 is provided at the upper end of the mounting shell 2. A mask insertion hole 301 is provided at the rear of the upper side of the end cap 3 for inserting a mask or mouthpiece; an inner conical shell 4 is fixedly connected to the middle of the lower side of the mounting shell 2, and the inner conical shell 4 is connected to the miniature compressor in the grip body 1. The inner diameter of the inner conical shell 4 gradually decreases from bottom to top to increase the speed at which compressed air is ejected from the inner conical shell 4; an outer conical shell 5 is provided between the end cap 3 and the inner conical shell 4, and a... The device has a main connecting arm 6, a connecting rod 7 in the middle of the end cap 3, a partition 8 fixedly connected to the lower end of the connecting rod 7, the partition 8, the inner conical shell 4 and the outer conical shell 5 are coaxial, and the diameter of the partition 8 is larger than the minimum inner diameter of the inner conical shell 4 and the outer conical shell 5. The partition 8 is used to allow the gas carrying the liquid medicine to impact. A drug storage rubber stopper 9 is embedded in the end cap 3 at the position corresponding to the main connecting arm 6. A drug storage bag 10 is fixedly connected between the drug storage rubber stopper 9 and the main connecting arm 6. The drug storage bag 10 is used to store the liquid medicine. A main suction groove 401 is provided on the right side of the inner conical shell 4. The main connecting arm 6 is used to transport the liquid medicine in the drug storage bag 10 to the main suction groove 401. The main suction groove 401 is used to allow the liquid medicine in the main connecting arm 6 to flow.

[0022] By storing the medication in the drug reservoir 10, the medication can be used directly when a patient suddenly develops an acute respiratory illness, without the need for temporary injection. Furthermore, by using the drug reservoir 10 to store the medication, the patient does not need to remain upright or seated during nebulization, thus improving ease of use and comfort.

[0023] In this embodiment, the mounting shell 2 is fixedly connected to the end cap 3; the end cap 3 is fixedly connected to the outer conical shell 5 through a bracket, and the inner conical shell 4 is fixedly connected to the outer conical shell 5; the end cap 3 is fixedly connected to the connecting rod 7.

[0024] In use, the liquid medicine is drawn into the syringe, and then the syringe needle is passed through the drug storage stopper 9 to connect the syringe with the inside of the drug storage sac 10. The liquid medicine is then injected into the drug storage sac 10, causing the drug storage sac 10 to change from a flat state to a bulging state. Then the needle is removed from the drug storage stopper 9, and the hole in the drug storage stopper 9 through which the needle passed closes by its own elasticity, thereby enabling the storage of the liquid medicine.

[0025] During nebulization, the micro compressor inside the grip body 1 is activated, injecting compressed air into the inner conical shell 4. The compressed air is ejected at high speed from the upper end of the inner conical shell 4, reducing the pressure at the upper end of the inner conical shell 4. Under the action of negative pressure, the liquid medicine in the drug reservoir 10 enters the main suction tank 401 through the main connecting arm 6 and mixes with the compressed air. The compressed air carries the liquid medicine and collides with the partition 8, causing the liquid medicine to be "broken" into droplets. The atomized liquid medicine flows with the compressed air in the mounting shell 2 and is discharged through the mask socket 301. The patient inhales the atomized liquid medicine through the mask or mouthpiece through the mask socket 301. After nebulization, the micro compressor inside the grip body 1 stops working.

[0026] Example 2 Based on Example 1, such as Figures 2 to 4 As shown, the mounting shell 2 and the end cover 3 are rotatably connected in a sealed manner, and a sealing ring (such as...) is provided between the periphery of the end cover 3 and the mounting shell 2. Figure 3 As shown), the inner conical shell 4 and the outer conical shell 5 are connected in a sealed rotational manner; three fixed buckles 302 are provided on the lower side of the end cover 3, which are equidistantly distributed in an annular shape. The fixed buckles 302 are made of elastic medical plastic. A fixed ring groove 303 is provided on the mounting shell 2 near the fixed buckles 302. The fixed buckles 302 limit the end cover 3 through the fixed ring groove 303, thereby maintaining the rotational connection between the mounting shell 2 and the end cover 3 by using the limiting state of the fixed buckles 302 and the fixed ring groove 303.

[0027] By rotating the end cap 3, the outer conical shell 5 is rotated, causing the main connecting arm 6 to be misaligned and disconnected from the main liquid suction groove 401. This prevents the liquid from overflowing from the liquid storage sac 10 when it is subjected to accidental impact or tilting during the storage of the liquid, thus maintaining the cleanliness and sufficiency of the liquid.

[0028] In this embodiment, the end cap 3 and the outer conical shell 5 are fixedly connected by a bracket.

[0029] like Figure 3 and Figure 4 As shown, a secondary connecting arm 11 is provided on the left side of the lower part of the outer conical shell 5. The secondary connecting arm 11 is symmetrically distributed with the main connecting arm 6. A liquid storage plug 12 is embedded in the end cap 3 at the position corresponding to the secondary connecting arm 11. A liquid storage bladder 13 is fixed between the secondary connecting arm 11 and the liquid storage plug 12. The liquid storage bladder 13 is used to store cleaning fluid, and the secondary connecting arm 11 is used to transport the cleaning fluid in the liquid storage bladder 13 to the main suction tank 401.

[0030] By changing the relative position of the outer conical shell 5 and the inner conical shell 4, the communication state between the main connecting arm 6 and the secondary connecting arm 11 and the main suction tank 401 can be switched. After atomization, the cleaning liquid can be atomized to clean the residual liquid on the main suction tank 401, the inner conical shell 4, the outer conical shell 5 and the partition block 8. Short-term use does not require disassembly for cleaning, making cleaning convenient. If not used for a long time, the end cap 3 can be removed to clean the mounting shell 2, the inner conical shell 4, the outer conical shell 5 and the partition block 8.

[0031] Example 3 Based on Example 2, such as Figures 2 to 5 As shown, an interceptor shell 14 is fixed to the middle of the lower side of the end cap 3. The connecting rod 7 passes through the interceptor shell 14, which covers the upper part of the outer conical shell 5. An exhaust port 141 is provided at the front of the upper side of the interceptor shell 14. The exhaust port 141 and the partition block 8 are misaligned in the vertical direction. After the collision, the atomized liquid flows with the compressed air. The compressed air drives the atomized liquid to change its flow direction after contacting the upper side inside the interceptor shell 14. Under the inertia of the large liquid droplets, the large droplets collide with the interceptor shell 14 and adhere to the inner wall of the interceptor shell 14. The small liquid droplets are discharged from the exhaust port 141 with the compressed air, thereby ensuring the atomization effect of the liquid.

[0032] like Figures 2 to 4 As shown, the lower part of the interceptor shell 14 is provided with a drainage cone 142. The inner diameter of the drainage cone 142 gradually decreases from top to bottom. The outer cone shell 5 is fixedly connected to the drainage cone 142. The outer cone shell 5 has annularly distributed, uniformly arranged connecting holes 501 near the drainage cone 142. The drainage cone 142 is used to drain the liquid medicine adhering to the inner side of the interceptor shell 14 to the connecting holes 501. The inner cone shell 4 is provided with annularly distributed, uniformly arranged secondary suction grooves 402 corresponding one-to-one with the connecting holes 501. The secondary suction grooves 402 are used to communicate with the corresponding connecting holes 501. The number of connecting holes 501 and secondary suction grooves 402 is not less than four and is an integer multiple of two. In this paper, the connecting holes 501 and secondary suction grooves 402 are... The atomizer has four liquid inlets 402, giving it three working states: the main connecting arm 6 and the connecting hole 501 are connected to the main liquid inlet 401 and the auxiliary liquid inlet 402 respectively; the auxiliary connecting arm 11 and the connecting hole 501 are connected to the main liquid inlet 401 and the auxiliary liquid inlet 402 respectively; and only the connecting hole 501 is connected to the auxiliary liquid inlet 402. After cleaning the inside of the atomizer with cleaning fluid, by switching the atomizer to the state where only the connecting hole 501 is connected to the auxiliary liquid inlet 402, not only can the liquid in the drug reservoir 10 and the liquid reservoir 13 be sealed and preserved, but the cleaning fluid accumulated at the connecting hole 501 can also be atomized and discharged, thereby improving the cleanliness of the atomizer and making it easy to carry.

[0033] The large-diameter liquid intercepted by the interceptor shell 14 is diverted by the diversion cone 142, so that the large-diameter liquid is collected at the connecting hole 501. The liquid is then re-absorbed by the Venturi effect and mixed with compressed air, thereby improving the utilization rate of the liquid.

[0034] Example 4 Based on Example 3, such as Figures 2 to 4 As shown, the connecting rod 7 is threadedly connected to the interceptor housing 14, the upper end of the connecting rod 7 passes through the end cover 3 and is rotatably connected to the end cover 3, and a knob 15 is fixedly connected to the upper end of the connecting rod 7.

[0035] By changing the axial distance between the partition block 8 and the outer conical shell 5 through the connecting rod 7, the probability of the liquid medicine in the compressed air colliding with the partition block 8 is changed, thereby controlling the concentration of the atomized liquid medicine in the compressed air and improving the applicability of the nebulizer to respiratory diseases of different degrees.

[0036] Example 5 like Figure 3 and Figure 4 As shown, a positioning post 17 is slidably connected to the front part of the end cover 3. The lower end of the positioning post 17 is hemispherical. A spring 16 is fixed between the upper side of the positioning post 17 and the end cover 3. Three positioning grooves 171 are provided on the upper side of the mounting shell 2 for limiting the positioning post 17. The groove depth of the positioning grooves 171 is less than the radius of the hemispherical part of the positioning post 17.

[0037] By rotating the end cap 3 to change the relative position of the end cap 3 and the mounting shell 2, the three states of the atomizer can be switched. After the switching is completed, the positioning groove 171 at the corresponding position limits the positioning post 17 to keep the relative position of the end cap 3 and the mounting shell 2 unchanged, thereby reducing the probability of misoperation of the atomizer during carrying and moving.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating this application and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this application.
