Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a hollow shaft motor. Background Art

[0002] Common electrical appliances in the consumer market include juicers, soymilk makers, ice cream machines, cooking machines, grinders, blenders, etc. Such electrical appliances all have a feature that a driving device is provided in the electrical appliance, and an output member (tool assembly) is connected to the transmission shaft of the driving device, and the output member is driven to rotate by the driving device. For example, the utility model with the publication number CN219374455U discloses a wall breaker, which includes a base assembly, a body assembly and an outer cover... The body assembly includes a cup body and a cup seat located below the cup body, and the accommodating structure provides an installation space for the cup seat; a power component for processing the food in the cup body and a wind blade for dissipating heat from the power component are provided in the cup seat... The airflow generated by the wind blade circulates internally in the closed space where the inner cavity, the heat insulation space and the internal space of the cup seat are located to cool the motor. Although the design of the wind blade will improve the cooling effect of the motor, when the wind blade rotates, it will drive the surrounding air to flow rapidly, so a relatively large noise will be generated, which will affect the daily rest of consumers and reduce the use experience of consumers.
