[0002] Compared with the traditional method of taking medicine to treat respiratory diseases such as asthma, the medical nebulizer atomizes the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through inhalation, thereby achieving painless, rapid and effective treatment. It belongs to the second category of medical devices. When using the traditional technology nebulizer, the mask is covered on the patient's mouth and nose, and the medicine supply machine continuously delivers the atomized medicine into the mask. The patient inhales the medicine during breathing. At the same time, the mask is provided with an exhaust hole, which indirectly causes the waste of the atomized medicine. That is, when the patient inhales, he inhales the atomized medicine provided by the medicine supply machine, but when the patient exhales, the exhaled air and the atomized medicine provided by the medicine supply machine are discharged together, which directly causes the waste of the atomized medicine. For this reason, the present invention provides a leak-free nebulizer and air replacement component with a fitting operation. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The medicine machine of the present invention manufactures and supplies atomized medicine, but the atomized medicine is not directly delivered to the mask, but temporarily stored in a medicine bag. When the patient inhales, the medicine in the medicine bag passes through the path where the medicine hose is located, and the medicine is sucked into the human body. The medicine in the medicine bag will gradually decrease. When the patient exhales, the exhaled waste gas is discharged through the waste gas hose. The atomized medicine delivery is actively controlled by the patient's breathing, thereby avoiding the waste problem caused by the continuous injection of atomized medicine into the mask in traditional technology.

[0015] 2. The present invention comprises an external motion device, a long axis and a push-pull device to form a medicine replenishing mechanism. The medicine replenishing mechanism collects the number of times the patient breathes after wearing a mask. When the number of breaths reaches a specified range, the atomized medicine in the medicine bag is consumed in large quantities. The medicine replenishing mechanism automatically controls the medicine machine to power on and the medicine machine replenishes the atomized medicine into the medicine bag. At the same time, the medicine replenishing mechanism also has a circuit-breaking mechanism. If the medicine bag is full of medicine, the medicine machine continues to transport medicine into the medicine bag, and the atomized medicine airflow will continue to be discharged through the exhaust group, thereby triggering the circuit-breaking mechanism in the medicine replenishing mechanism. Subsequently, the control of the medicine machine by the medicine replenishing mechanism ends, and the medicine machine that has been powered off stops replenishing medicine into the medicine bag.

[0042] The medicament machine 2 is an instrument of the prior art. The patient covers the mouth and nose with the mask 1, then presses the manual switch on the medicament machine 2. After the medicine bag 10 expands and becomes full, the manual switch is pressed backward, and the medicament machine 2 stops supplying the atomized medicament. Subsequently, the patient continuously breathes under atomization treatment. When the patient inhales, the negative pressure in the mask 1 causes the atomized medicament in the medicine bag 10 to be sucked into the transfer box 12, and then is sucked into the intake chamber of the ventilation box 17 through the neck tube 15. Next, it is sucked into the mask 1 through the medicament hose 8, and thus the atomized medicament is sucked into the human body. When the patient exhales, the exhaled waste gas is injected into the exhaust chamber of the ventilation box 17 through the waste gas hose 9 and then discharged through the exhaust group 18. During each breathing process, the movable plate 31 in the exhaust chamber of the ventilation box 17 swings once. In the medicine replenishing mechanism composed of the outer moving device 20, the long shaft 22 and the pushing and pulling device 23, there is a swing number recording mechanism. If the swing number of the movable plate 31 reaches the specified range, the medicament supply work in the medicine bag 10 will be automatically triggered, that is, the pushing and pulling device 23 drives the second switch on the medicament machine 2, and the medicament machine 2 is powered on to manufacture and externally discharge the atomized medicament. Each swing of the movable plate 31 corresponds to one breath of the patient. The patient's breathing will consume the atomized medicament in the medicine bag 10. Therefore, when breathing reaches the specified number of times, the atomized medicament in the medicine bag 10 will be exhausted, and thus the subsequent medicament supply work will be automatically triggered.

[0043] The principle of collecting the breathing times is as follows: When the patient exhales, the waste gas impacts the movable plate 31 when being externally discharged through the waste gas hose 9. The swing of the movable plate 31 drives the door shaft 33. The reciprocating rotation of the door shaft 33 will drive the ring gear 26 to rotate, and then the worm 28 is controlled to rotate intermittently and directionally through the one-way bearing 27. Subsequently, the disk gear 30 slowly rotates to drive the short shaft 29. Next, the long shaft 22 is driven through the double-control gear 40. The rotation of the long shaft 22 causes the clockwork spring 57 to contract and store energy. After the energy storage is sufficient, the control cylinder 56 breaks through the blocking of the stop spring piece 54 and rotates one circle. The control cylinder 56 drives the fan shaft 52, and thus the fan 51 rotates rapidly, generating a directional air flow in the air duct 53. The air flow is injected into the push-pull plate 47 through the flat tube 50, and the push-pull plate 47 is impacted and rises. The push-pull plate 47 is externally connected to the switch handle on the medicament machine 2, and thus the pushing of the handle is realized. After the control cylinder 56 in the present invention rotates one full circle, it will be intercepted by the stop spring piece 54 again. At the same time, the air flow impact on the push-pull plate 47 disappears, and the push-pull plate 47 falls back to control the medicament machine 2 to stop working, that is, the replenishment of the medicine bag 10 is completed.

[0044] If the medicine cartridge 10 is pre-filled with atomized medicine in advance and the medicine machine 2 continues to work to replenish the medicine, the excess atomized medicine will be directly discharged and wasted. Specifically, after the medicine cartridge 10 is full, the atomized medicine is continuously injected. The medicine airflow passes through the neck tube 15, the intake chamber of the air exchange box 17, the medicine hose 8, the face mask 1, the waste gas hose 9, and the exhaust chamber of the air exchange box 17 in sequence, and then is directly discharged through the nozzle tube 37. When a person exhales with a short breath, the circuit-breaking mechanism will not be triggered, and the atomized medicine supplied by the medicine machine 2 will continue to be discharged. When the exhalation becomes longer, the subsequent circuit-breaking mechanism will be triggered, that is, the medicine replenishing mechanism also has a circuit-breaking mechanism.

[0045] Principle of the circuit-breaking mechanism: The medicine is continuously discharged, and the medicine airflow continuously impacts the fluid wheel 36. The rotation of the fluid wheel 36 drives the outer moving shaft 35. The rotation of the outer moving shaft 35 causes the concave folding plate 41 to translate, and then drives the double-control gear 40 to move axially through the double-control shaft 39. Figure 10 After the double-control gear 40 in [description] moves to the right and separates from the positioning gear 38, the transmission between the short shaft 29 and the long shaft 22 is interrupted. Although the previous exhalation of the patient will also cause the double-control gear 40 to move axially, the moving distance is short and will not cause the transmission between the short shaft 29 and the long shaft 22 to be interrupted. After the patient's exhalation ends, the spring 42 presses to make the double-control gear 40 quickly move in the reverse direction and reset. However, the continuous impact of the atomized medicine airflow directly causes the transmission between the short shaft 29 and the double-control gear 40 to be interrupted. Next, the long shaft 22 is quickly rotated by the reverse drive of the clockwork spring 57. The clockwork spring 57 originally released the driving pressure on the control cylinder 56. After the long shaft 22 got out of control, the pressure accumulated in the clockwork spring 57 was quickly released through the long shaft 22, and the rotation of the control cylinder 56 automatically terminated. The subsequent transmission control caused the push-pull plate 47 to fall back, and then the medicine machine 2 stopped the medicine replenishing work.
