[0002] A Chinese utility model patent with application number CN202322725569.1, entitled "An Atomizable Eye Drug Delivery Device," discloses an atomizable eye drug delivery device. It employs two separate silicone cover plates, a first and a second, to clamp the atomizing plate, covering its perimeter. Based on the elastic deformation of the silicone material and the pressure applied by the cover, a sealed space is formed at the atomization port. The silicone protects the atomizing plate and forms a sealing structure after compression. The addition of an annular ring further enhances the sealing, effectively preventing leakage. Furthermore, the atomizing unit uses magnetic attraction, and by placing the magnet's end face externally, the overall magnetic force is stronger, making it less likely to fall off. However, the bottle body and the atomizing part of this utility model are separate and independent. When in use, the bottle body is inverted and fixed together with the internal thread of the connection port of the atomizing part through the external thread, so that the medicine enters the atomizing part. It is not convenient to use and there is room for improvement. Therefore, the structure of the device needs to be further improved. Summary of the Invention
