[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] An inhalation device for small nucleic acid drugs, such as Figures 1-6 As shown, the device includes a medicine storage cylinder 1, a bottom box 2 at the bottom of the medicine storage cylinder 1, and a top cover 5 threadedly connected to the top of the medicine storage cylinder 1. The top cover 5 is equipped with a scraping component 9. The scraping component 9 includes a movable shaft 904 mounted on the top cover 5 via a sealed bearing 902 and a slide groove 907 opened inside the top of the top cover 5. Multiple sliders 906 are arranged inside the slide groove 907, and a gear ring 901 is installed at the bottom of the slider 906. The slide groove 907 is annular in shape. The sliders 906 are slidably connected to the slide groove 907. When the gear ring 901 rotates, it will drive the sliders 906 to slide inside the slide groove 907, thereby improving the stability of the gear ring 901 when rotating. A gear 905 is installed at the bottom of the movable shaft 904, and a turntable 903 is connected to the top of the movable shaft 904.

[0040] Specifically, a scraper 908 is installed on one side of the bottom of the gear ring 901. When it is necessary to scrape off the powder adhering to the inner wall of the medicine storage cylinder 1, the movable shaft 904 can be rotated by the turntable 903. The movable shaft 904 drives the gear 905 to rotate, which in turn drives the gear ring 901 to rotate. One side of the scraper 908 is in contact with the inner wall of the medicine storage cylinder 1, and the bottom of the scraper 908 is in contact with the inner wall of the feed hopper 4. The rotation of the scraper 908 can scrape off the powder adhering to the inner wall of the medicine storage cylinder 1, avoiding a large amount of powder remaining on the inner wall of the medicine storage cylinder 1. The gear 905 meshes with the gear ring 901 so that when the gear 905 rotates, it can drive the gear ring 901 to rotate, which in turn drives the scraper 908 to rotate.

[0041] Specifically, the inside of the medicine storage cylinder 1 is provided with a lower hopper 4, the bottom end of the lower hopper 4 is provided with a lower feeding pipe 14, and the bottom end of the lower feeding pipe 14 is provided with a lower feeding disc 6. The medicine powder falls into the lower feeding pipe 14 from the lower hopper 4, and then falls into the lower feeding disc 6, which is convenient for subsequent feeding. A plurality of first through holes 15 are formed in the lower feeding disc 6. One side of the bottom box 2 is provided with a suction outlet 3, which is convenient for discharging the medicine powder. The first through holes 15 are arranged so that the medicine powder can fall into them. The other side of the bottom box 2 is provided with an air inlet pipe 10, and external gas can enter the inside of the bottom box 2 through the air inlet pipe 10.

[0042] Referring to Figures 1-4 , the bottom box 2 is threadedly connected with a threaded rod 13. One end of the threaded rod 13 is connected with a blocking disc 7 through a bearing. A plurality of second through holes 16 are formed in the blocking disc 7. When the threaded rod 13 rotates, it moves, and drives the blocking disc 7 to move, so as to adjust the position of the blocking disc 7. The bottom side of the blocking disc 7 is provided with a connecting rod 12, and the end of the connecting rod 12 is connected with a baffle 17. When the blocking disc 7 moves, it drives the connecting rod 12 to move, and then drives the baffle 17 to move, so as to adjust the position of the baffle 17. One side of the baffle 17 is attached to the air inlet pipe 10. The number of the first through holes 15 is the same as that of the second through holes 16, and the diameter of the first through holes 15 is the same as that of the second through holes 16. When the first through holes 15 and the second through holes 16 are misaligned, the medicine powder in the medicine storage cylinder 1 cannot fall into the inside of the bottom box 2. The top of the blocking disc 7 is attached to the upper side of the inside of the bottom box 2. The other end of the threaded rod 13 is provided with a knob. When it is necessary to move the blocking disc 7, the staff can rotate the threaded rod 13 through the knob, so that the threaded rod 13 moves and drives the blocking disc 7 to move.

[0043] Example two:

[0044] On the basis of the above-mentioned example one, in order to ensure that the first through holes 15 can be accurately aligned with the second through holes 16, the following structure is arranged.

[0045] Referring to Figures 2-3 , the inside of the bottom box 2 is provided with a stop block 8. When one side of the blocking disc 7 moves to contact the stop block 8, the blocking disc 7 is difficult to continue to move. At this time, the first through holes 15 and the second through holes 16 are accurately aligned, which is convenient for feeding.

[0046] Example three:

[0047] On the basis of the above-mentioned example one, in order to prevent external impurities from entering the inside of the bottom box 2 through the air inlet pipe 10, the following structure is arranged.

[0048] Referring to Figures 1-2 , the air inlet pipe 10 is provided with a filter screen 11. The filter screen 11 can filter the gas, preventing impurities from entering the inside of the bottom box 2 through the air inlet pipe 10.

[0049] The working principle of the utility model is: firstly, when using the suction device, the threaded rod 13 can be rotated first, so that the threaded rod 13 moves and drives the plugging disc 7 to move, when one side of the plugging disc 7 moves to contact the stopper 8, the threaded rod 13 is not rotated any more, at this time, the first through hole 15 and the second through hole 16 are aligned, at the same time, the plugging disc 7 moves and drives the connecting rod 12 to move, and then drives the baffle 17 to move, so that the baffle 17 no longer blocks the air inlet pipe 10, then the suction outlet 3 can be used to inhale air, the medicine powder falls into the discharge pipe 14 through the first through hole 15 and the second through hole 16, and then falls into the bottom box 2, and then is discharged through the suction outlet 3, when the device is not used, the threaded rod 13 is reversely rotated, so that the threaded rod 13 drives the plugging disc 7 to reset and move, and the first through hole 15 and the second through hole 16 are misaligned, so that the medicine powder is prevented from falling randomly, at the same time, the baffle 17 resets and blocks the air inlet pipe 10;

[0050] When the medicine powder adhered to the inner wall of the medicine storage cylinder 1 needs to be scraped, the user can rotate the disc 903 to rotate the movable shaft 904, the movable shaft 904 drives the gear 905 to rotate, and then drives the gear ring 901 to rotate, the gear ring 901 drives the scraping rod 908 to rotate, and the scraping rod 908 rotates to scrape the medicine powder adhered to the inner wall of the medicine storage cylinder 1 and the discharge hopper 4, so that a large amount of medicine powder is prevented from remaining on the inner wall of the medicine storage cylinder 1.

[0051] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, and the person skilled in the art can make non-creative contribution modifications, replacements and changes of the embodiments according to the needs after reading the specification without departing from the principles and the purpose of the utility model, but as long as in the range of the claims of the utility model, it is protected by the patent law.
