It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0023] like Figures 1-4 As shown, the heat dissipation mechanism at the bottom of the appliance, such as a blender or juicer, includes a bottom shell 1, a drive unit 2, and a fan shroud 3. The drive unit 2 is installed in the middle of the bottom shell 1 and can be fixed in the appliance with fasteners (not shown in the figure). An outer shell (not shown in the figure) is also installed on the bottom shell 1. The fan shroud 3 covers the drive unit 2 and encloses the drive unit 2 and the bottom shell 1, guiding the airflow. Several heat dissipation holes are provided on the outer periphery of the bottom shell 1. A fan blade 4 is installed on one output shaft of the drive unit 2. The drive unit 2 drives the fan blade 4 to rotate, stirring the surrounding air and quickly dissipating the heat generated inside the appliance, thereby improving heat dissipation efficiency and extending the service life of the appliance.

[0024] Specifically, some of the heat dissipation holes form the air inlet group 5, and some of the heat dissipation holes form the air outlet group 6. External air enters the appliance through the air inlet group 5, and internal heat is discharged through the air outlet group 6.
