The air conditioner comprises a motor and the shell assembly, and the motor is connected to the mounting structure of the shell assembly. The supporting ribs in the shell assembly can improve the strength and stability of the mounting structure and the shell at the same time, the structure is simple, the functionality is high, and the operation stability of the motor and the air conditioner can be ensured.

This utility model relates to the field of medical device technology, and discloses a loading device and a loading system. The loading device is used to accommodate valves and valve clips. The loading device includes a shell with a receiving cavity and a filter structure disposed within the shell. By setting the filter structure, the shell can be divided into a first receiving area for accommodating the valves and valve clips and a second receiving area for accommodating cooling substances. The filter structure can block solids, i.e., ice slag, in the cooling substances from entering the second receiving area, allowing only the liquid in the cooling substances to enter the first receiving area to cool the valves and valve clips. This avoids contact between ice slag and the valves, preventing damage to the valves, thereby achieving the technical effect of improving the stability of valve performance and preventing ice slag from entering the human body, thus improving the stability of the implantation procedure.
