[0028] Among them, a rotating plate 15 is movably installed inside the screw cap 2. A first ventilation opening 22 is opened inside the rotating plate 15. A first fixing plate 14 is fixedly installed inside the screw cap 2. A second ventilation opening 25 is opened inside the first fixing plate 14. A middle column 9 is fixedly installed at the bottom of the rotating plate 15. A housing 7 is fixedly installed at the bottom of the rotating plate 15. An air inlet 19 is opened at the bottom of the housing 7.

[0029] The outer surface of the central column 9 is fixedly installed with a display plate 16. The top of the display plate 16 is fixedly installed with a pressing block 17, and the bottom of the display plate 16 is fixedly installed with a flow blocking plate 18.

[0030] The staff holds the outer shell 7 and drives the rotary cover 2 to rotate inside the rotary plate 15 through the outer shell 7. When the first vent 22 coincides completely with the second vent 25 inside the first fixing plate 14, gas slowly flows into the inside of the rotary cover 2 and the suction nozzle 3 through the second vent 25 and the first vent 22. Then, the staff slowly bites the suction nozzle 3 with the mouth and then inhales. Through inhalation, through the cooperation among the display plate 16, the pressing block 17 and the flow blocking plate 18, it slowly moves upward on the outer surface of the rotary plate 15. Through the cooperation between the magnet 10 and the pressing block 17, the display plate 16 and the flow blocking plate 18 will not drop due to gravity during use, so as to observe the position of the display plate and compare the inhalation effect.

[0031] Hold the outer shell 7 and drive the rotary cover 2 to rotate inside the rotary plate 15 through the outer shell 7. When the first vent 22 coincides completely with the second vent 25 inside the first fixing plate 14, gas slowly flows into the inside of the rotary cover 2 and the suction nozzle 3 through the second vent 25 and the first vent 22. Then, the staff slowly bites the suction nozzle 3 with the mouth and then inhales. The gas enters the inside of the outer shell 7 through the air inlet 19. Through the cooperation among the display plate 16, the pressing block 17 and the flow blocking plate 18, it slowly moves upward on the outer surface of the rotary plate 15. Through the cooperation between the magnet 10 and the pressing block 17, the display plate 16 will not drop due to gravity during use, so as to observe the position of the display plate and compare the inhalation effect. Compared with the traditional device, this device adjusts the inhalation amount through the cooperation between the second vent 25 and the first vent 22. Through the cooperation between the pressing block 17 and the magnet 10, the display plate 16 and the flow blocking plate 18 will not drop due to gravity during use, so as to observe the position of the display plate and compare the inhalation effect, ensuring that after the display plate 16 moves to the specified position, it will not drop automatically due to gravity, which is convenient for users to accurately observe the inhalation effect. In addition, the device is also equipped with a flexible adjustment device, and users can easily adjust the inhalation amount according to personal needs, so as to meet the use needs of different people. The innovative design not only facilitates the testing process, but also greatly improves the user experience.

[0032] Among them, a support column 4 is fixedly installed inside the support plate 1. A reinforcing rib 5 is fixedly installed at the included angle between the support plate 1 and the support column 4. And the reinforcing rib 5 presents a triangular shape.

[0033] Since a reinforcing rib 5 is fixedly installed at the corner between the support plate 1 and the support column 4, the support plate 1 is supported by the reinforcing rib 5, ensuring the stability of the support plate 1 during use and improving the use efficiency of the support plate 1.

[0034] Among them, a second fixing plate 24 is fixedly installed at the bottom of the support column 4, and a placement plate 8 is fixedly installed on the top of the second fixing plate 24.

[0035] Through the cooperation between the placement plate 8 and the second fixing plate 24, it is convenient for the housing 7 to pass through the support plate 1 and enter the interior of the placement plate 8. The placement plate 8 supports the housing 7, improving the fixing efficiency of the housing 7.

[0036] Among them, a magnet 10 is installed on the outer surface of the middle column 9, and the pressing block 17 is made of a metal material.

[0037] Since the pressing block 17 is made of a certain material, through the cooperation between the magnetism of the magnet 10 and the pressing block 17, the pressing block 17 will not fall down due to gravity, improving the use efficiency of the pressing block 17.

[0038] Among them, the limiting blocks 21 are in four sizes on the outer surface of the suction nozzle 3, and the suction nozzle 3 is made of rubber.

[0039] Since the limiting blocks 21 are made of rubber and the limiting blocks 21 are in four identical sizes on the outer surface of the suction nozzle 3, by simultaneously entering the interior of the limiting slots 20, the suction nozzle 3 is fixed more stably.

[0040] Among them, the outer diameter value of the limiting block 21 is equal to the inner diameter value of the limiting slot 20, and the interior of the limiting slot 20 is designed with a smooth surface.

[0041] Since the interior of the limiting slot 20 is designed with a smooth surface and the outer diameter value of the limiting block 21 is equal to the inner diameter value of the limiting slot 20, it is convenient to quickly move the limiting block 21 into the interior of the limiting slot 20, improving the fixing efficiency of the limiting slot 20 for the limiting block 21.

[0042] Among them, the first ventilation openings 22 are in a circumferential array on the rotating plate 15, and the inner diameters between the rotating plate 15 and the second ventilation openings 25 are equal.

[0043] Since the first ventilation openings 22 are in a circumferential array on the rotating plate 15 and the inner diameters between the rotating plate 15 and the second ventilation openings 25 are equal, when the second ventilation openings 25 are connected to the rotating plate 15, the drug inhalation flow rate is the largest, improving the drug inhalation efficiency.

[0044] The working principle and usage process of the present utility model:

[0045] The staff holds the outer shell 7 and drives the rotary cap 2 to rotate inside the rotary plate 15 through the outer shell 7. When the first vent 22 coincides completely with the second vent 25 inside the first fixed plate 14, gas slowly flows into the inside of the rotary cap 2 and the suction nozzle 3 through the second vent 25 and the first vent 22. Then, the staff slowly bites the mouth on the suction nozzle 3 and inhales. Through inhalation, with the cooperation among the indicating disc 16, the pressing block 17 and the flow blocking disc 18, it slowly moves upward on the outer surface of the rotary plate 15. With the cooperation between the magnet 10 and the pressing block 17, the indicating disc 16 and the flow blocking disc 18 will not drop due to gravity during use, so as to observe the position of the indicating disc and compare the inhalation effect.

[0046] Before using the suction nozzle 3, the staff needs to fixedly install the suction nozzle 3 inside the rotary cap 2. By holding the suction nozzle 3 by hand, slowly align the limiting block 21 on the outer surface of the suction nozzle 3 with the inside of the fixing groove 6. Slide the suction nozzle 3 inside the fixing groove 6, and drive the fixing bracket 23 to synchronously descend through the fixing groove 6. Then, slowly enter the inside of the fixing block 13 through the fixing bracket 23 to squeeze the spring 12. Support the fixing block 13 through the connecting column 11, squeeze the spring 12 through the fixing bracket 23, and then rotate the limiting block 21 clockwise inside the fixing groove 6 so that the limiting block 21 slowly enters the inside of the limiting groove 20. Squeeze the fixing bracket 23 through the rebounding effect of the spring, and squeeze the suction nozzle 3 and the limiting block 21 through the fixing bracket 23, so that the limiting block 21 is quickly fixed in the limiting groove 20, thus completing the disassembly and assembly of the suction nozzle 3 and the rotary cap 2.
