[0002] In modern medical technology, the routes of administration to patients usually include oral, inhalation, sublingual, topical, rectal, injection, etc. Since oral or nasal inhalation allows the drug to be directly absorbed into the blood through the oral or nasal mucosa, it can bypass the "first pass" effect of the liver. Therefore, for the treatment / administration of many diseases (the most common is asthma), the most effective method of administration is oral (or nasal) inhalation. Inhalation drug delivery devices are used in the clinical practice of respiratory medicine.

[0003] For example, the Chinese patent with the publication number CN214926553U discloses an injection mold for a high-efficiency inhalation drug delivery device, which relates to the field of injection mold technology, including a lower shell, the bottom end of the lower shell is fixedly connected to a limit box, the upper surface of the limit box is movably connected to threaded sleeves at the four corners through bearings, the inner top middle of the limit box is fixedly connected to a fixed block, the middle of the fixed block is provided with a fixed groove, a movable rod is inserted in the fixed groove, and both ends of the movable rod are movably connected to the bottom end of the threaded sleeve through a bevel gear group. The utility model sets a limit box at the bottom end of the lower shell, threaded sleeves are set at the four corners of the top of the limit box through bearings, and the bottom ends of the four threaded sleeves are connected in the limit box through a bevel gear group and a movable rod, and the threaded sleeve is rotated to rotate the movable rod, so that the threaded sleeve set at the bottom end of the upper shell is inserted into the threaded sleeve, so that the connection between the upper shell and the lower shell is tighter, so that the precision of the injection molded product is improved.

[0004] The above patent has the following problems:
