Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The specific scheme is as follows:
example 1
As shown in fig. 1 to 4, the food processor with the optimized air duct structure disclosed by the invention is an in-line food processor, and comprises a main machine 2 and a processing cup assembly 1 installed on the main machine 2, wherein the processing cup assembly 1 can be detachably connected with the main machine 2, and the processing cup assembly 1 is directly matched with the main machine 2 to process food materials.
