The transmission structure 8 also includes a driving gear 804, which is sleeved on the stirring rod 6, and the driving gear 804 is meshed with the driven gear 803. The stirring rod 6 and the vertical rod 801 are connected through the driving gear 80 4 is meshed with the driven gear 803 for transmission, and the rotation speed of the stirring rod 6 is faster than that of the vertical rod 801.

[0029] The specific operation is as follows: when in use, hold the medicine bin 1, and place the medicine dispensing nozzle 14 at the patient's breathing position, start the micro motor 5, and drive the stirring rod 6 and the stirring blade 7 to rotate through the micro motor 5 to stir the medicine to avoid precipitation of the effective ingredients in the medicine, which helps to control the amount of medicine more accurately. In this process, the stirring rod 6 is meshed with the driven gear 803 through the driving gear 804 to drive the vertical rod 801 to rotate, and then the second bevel gear 806 is meshed with the first bevel gear 802 to drive the horizontal rod 805 to rotate, thereby driving the extrusion block 903 to periodically squeeze the hose 902 inside the shell 901, and at the same time, the micro pump body 11 is started to pump the medicine bin. 1 is extracted, so that the medicine enters the hose 902 along the liquid extraction tube 10, and under the extrusion control of the material control component 9, the medicine enters the temporary storage bin 12 in an even and equal amount, and is atomized by the atomizer 13, and sprayed to the patient's breathing position by the medicine discharge nozzle 14 until the amount of medicine in the temporary storage bin 12 reaches the target dose, and the micro motor 5 stops operating. Through the transmission structure 8, the material control component 9 can be driven to operate while the medicine is uniform, and the amount of medicine entering the temporary storage bin 12 is strictly controlled. With the coordinated use of the material control component 9 and the stirring blade 7, the purpose of strictly controlling the dosage is achieved, so that the patient can accurately grasp the amount of medicine inhaled each time, avoid overdose or underdose, and thus help to improve the asthma treatment effect.

[0030] like Figure 1 and Figure 6 As shown, the transmission structure 8 is arranged inside the control box 4, and the control box 4 is provided with a material control component 9, the material control component 9 includes a shell 901, a hose 902 and an extrusion block 903, one end of the hose 902 is fixedly connected to a liquid extraction pipe 10, and the liquid extraction pipe 10 is connected in series with a micro pump body 11, the other end of the hose 902 is fixedly connected to a temporary storage bin 12, and the outer wall of the temporary storage bin 12 is fixedly connected to an atomizer 13, and the mist outlet of the atomizer 13 is fixedly connected to a medicine outlet nozzle 14, the top of the medicine bin 1 is fixedly connected to an air pressure balance component 15, and the air pressure balance component 15 includes a cover 1 501, a through groove 1502, a vent pipe 1503, an annular frame 1504 and a nitrogen bag 1505, a through groove 1502 is opened on the top of the cover 1501, and the vent pipe 1503 is fixedly connected to the bottom of the cover 1501, the annular frame 1504 is fixedly installed inside the cover 1501, and the nitrogen bag 1505 is fixedly connected to the top of the cover 1501, the top end of the vent pipe 1503 is connected to the bottom of the cover 1501, and the bottom end of the vent pipe 1503 is connected to the top of the medicine bin 1, and the cover 1501 is connected to the medicine bin 1 through the vent pipe 1503;

[0031] The specific operation is as follows. After the asthma medicine in the medicine bin 1 is extracted through the micro pump body 11, it will be sent to the material control component 9 and the temporary storage bin 12 along the liquid extraction tube 10. As the medicine in the medicine bin 1 decreases, the pressure in the medicine bin 1 decreases accordingly, so that the nitrogen stored in the nitrogen bag 1505 can enter the medicine bin 1 along the ventilation pipe 1503 under the action of the pressure difference to balance the pressure difference. When the nitrogen in the nitrogen bag 1505 is exhausted, the outside air can enter the cover shell 1501 through the through groove 1502 at the top of the cover shell 1501, so that the nitrogen bag 1505 is concave inward, which can also achieve the effect of balancing the pressure difference. Through the above design, not only can the pressure inside the medicine bin 1 be maintained stable, and the negative pressure in the medicine bin 1 caused by the reduction of the medicine can be avoided, which is conducive to the stability of the spraying operation of the spray device, but also the medicine can be prevented from contacting the outside air and accelerating deterioration, thereby improving the use effect of the device.

[0032] In summary, combined Figure 1-Figure 6 As shown, the working principle of the asthma spray device which is easy to control the dosage is as follows: first, hold the medicine bin 1 and place the medicine dispensing nozzle 14 at the patient's breathing position, then start the micro motor 5, and drive the stirring rod 6 and the stirring blade 7 to rotate through the micro motor 5 to stir the medicine. In this process, the stirring rod 6 is meshed with the driven gear 803 via the driving gear 804 to drive the vertical rod 801 to rotate, and then the second bevel gear 806 is meshed with the first bevel gear 802 to drive the horizontal rod 805 to rotate, thereby driving the squeezing block 903 to periodically squeeze the hose 902 inside the housing 901, and at the same time, start the micro pump body 11 to extract the medicine from the medicine bin 1, so that the medicine is pumped along the pump. The liquid pipe 10 enters the hose 902, and under the extrusion control of the material control component 9, enters the temporary storage bin 12 in an even and equal amount, and is atomized by the nebulizer 13 and sprayed toward the patient's breathing position by the medicine discharge nozzle 14 until the amount of medicine in the temporary storage bin 12 reaches the target dose. In the spraying process, as the amount of medicine in the medicine bin 1 decreases, the pressure in the medicine bin 1 decreases accordingly. The nitrogen stored in the nitrogen bag 1505 will enter the medicine bin 1 along the ventilation pipe 1503 under the action of the pressure difference to balance the pressure difference. When the nitrogen in the nitrogen bag 1505 is exhausted, the outside air can enter the cover 1501 through the through groove 1502 on the top of the cover 1501, causing the nitrogen bag 1505 to be concave inward, which can also achieve the effect of balancing the pressure difference.

[0033] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
