[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: like Figures 1-7 As shown, this embodiment of the invention provides a lung-targeted drug nebulization delivery device with respiratory triggering, including a housing 1. A drug storage tank 4 is fixedly connected to the upper end of the housing 1. A liquid lowering pipe 5 is fixedly connected to the lower end of the drug storage tank 4. An electromagnetic valve 6 is installed inside the liquid lowering pipe 5. An nebulization chamber 7 is fixedly connected to the lower end of the liquid lowering pipe 5. A piezoelectric ceramic vibrator 8 is installed inside the nebulization chamber 7. A vertical air passage 10 is fixedly connected to the lower end of the nebulization chamber 7. A microporous screen 9 is installed inside the connection port between the vertical air passage 10 and the nebulization chamber 7. A horizontal air pipe 11 is fixedly connected to one side of the vertical air pipe 10. The horizontal air pipe 11 is rotatably connected to a rotating air pipe 13 through a rotating groove 12 opened on the outer wall. A toothed ring 14 is sleeved on the outside of the rotating air pipe 13. A servo motor 15 is provided at the lower end of the vertical air pipe 10. A gear 16 is sleeved on the output end of the servo motor 15. The gear 16 meshes with the toothed ring 14. An electric telescopic rod 17 is provided at the lower end of the rotating vent pipe 13. A rack 18 is fixedly connected to the output end of the electric telescopic rod 17. Multiple guide plates 19 are rotatably connected to the outlet of the rotating vent pipe 13. The upper and lower ends of the multiple guide plates 19 are rotatably connected to the rotating vent pipe 13 through rotating rods. Gear 20 is sleeved on the outside of the multiple rotating rods at the lower end. The multiple gear 20 meshes with the rack 18. A partition 26 is fixedly connected to the lower end of the interior of the housing 1. An auxiliary air pump 27, a main circuit board 28, and a battery 29 are installed at the lower end of the partition 26. An actuator head 23 is fixedly connected to one side of the housing 1. Two differential pressure airflow sensors 24 are installed inside the actuator head 23. The respiratory trigger module enables simultaneous drug delivery during inhalation, and combined with a precise mechanical direction adjustment component, it can actively and accurately guide the drug beam to the target area of ​​the lungs, significantly improving drug utilization and treatment efficacy.

[0019] A guide rail 22 is fixedly connected to the outer wall of the rotating ventilation tube 13. A slider 21 that slides with the guide rail 22 is fixedly connected to the rack 18, providing precise guidance and support for the reciprocating motion of the rack 18. This ensures that the driving force of the electric telescopic rod 17 can be stably transmitted to the gear 20, thereby ensuring the synchronicity and reliability of the opening and closing actions of multiple guide plates 19 and preventing jamming or deviation during the movement. The end of the actuator 23 is detachably connected to a mouthpiece 25, which allows for easy disassembly, replacement, or disinfection of the mouthpiece 25. This effectively avoids the risk of cross-infection between different patients or multiple uses by the same patient, improving the hygiene and safety of the device and its ease of use. The outlet of the auxiliary air pump 27 is connected to the inlet of the horizontal ventilation tube 11 through an independent air pipe, realizing a separate design between the auxiliary airflow and the main drug path. This ensures a stable supply of auxiliary airflow, provides controllable delivery power for the drug mist, and avoids gas... The vibration or heat generated by the pump operation reduces interference with the core atomization components, improving the overall system stability and atomization quality. The upper shell 2 is threaded at the top of the housing 1, and the lower shell 3 is threaded at the bottom, making the assembly and disassembly of the housing 1 extremely convenient. This facilitates assembly during production and maintenance, repair, and parts replacement during later use, significantly reducing production and maintenance costs. A touchscreen 30 for user interaction is fixedly connected to one side of the housing 1, providing users with an intuitive and intelligent operating interface. Users can easily set treatment parameters and monitor equipment status, greatly simplifying the operation process and improving the device's intelligence and user experience. An air intake grille 31 is provided on one side of the housing 1, providing necessary cooling channels for the internal electronic components and auxiliary air pump 27, effectively reducing the heat generated during equipment operation, ensuring stable operation of all components at suitable temperatures, and extending the device's service life.

[0020] Working principle: First, during the system preparation phase, the user sets treatment parameters via the touchscreen 30 fixed to one side of the housing 1, such as targeting the upper left lobe of the lung. The main circuit board 28 receives and stores these instructions. At this time, the liquid medicine stored in the drug reservoir 4 flows to the lower liquid pipe 5 due to gravity, but is temporarily prevented from flowing out by the closed solenoid valve 6, and the entire device is in standby mode.

[0021] When the patient takes the mouthpiece 25 at the end of the actuator head 23 into their mouth and begins to breathe, the respiratory monitoring and triggering phase is initiated. Two differential pressure airflow sensors 24 integrated inside the actuator head 23 monitor pressure changes within the breathing channel in real time. When the patient begins to inhale, the sensors detect a specific positive pressure difference and immediately send this "inhalation" signal to the main circuit board 28. The built-in algorithm on the main circuit board 28 confirms the start of inhalation, instantly generates a trigger command, and initiates the nebulization and guided execution phase.

[0022] Upon receiving the trigger signal, the main circuit board 28 simultaneously executes several precision operations: First, it controls the opening of the solenoid valve 6, allowing the liquid medicine to flow into the atomization chamber 7, while simultaneously driving the piezoelectric ceramic vibrator 8 to vibrate at high frequency, causing the liquid medicine to pass through the microporous screen 9 to form uniform drug mist particles; Second, it first drives the electric telescopic rod 17 to extend, pushing the rack 18 to slide along the guide rail 22, thereby driving multiple gears 20 to rotate synchronously, precisely adjusting the deflection angle of the guide plate 19 to control the blowing angle of the drug mist beam; Subsequently, according to the preset target, it drives the servo motor 15 to rotate, and through the meshing transmission of gear 16 and gear ring 14, drives the entire rotating ventilation tube 13, which has been set at a certain angle, to rotate, so that its final blowing position is precisely aligned with the target area of ​​the lungs. At the same time, the auxiliary air pump 27 located in the lower layer of the housing 1 starts, injecting clean air into the airflow channel through an independent air tube, providing additional delivery power for the drug mist.

[0023] Finally, during the drug delivery phase, the high-concentration drug mist, propelled by the auxiliary airflow, forms a concentrated jet that sequentially passes through the vertical airway 10, the horizontal airway 11, and the oriented rotating airway 13, before being ejected at high speed from the precisely angled guide plate 19. This mist is then accurately inhaled by the patient and directly reaches the lung lesions. When the sensor detects an exhalation signal, the main circuit board 28 immediately instructs all components to reset, closing the solenoid valve 6 and the guide plate 19, awaiting the next inhalation trigger. This cycle continues until the treatment is complete.
