AI Technical Summary
The centralized heat dissipation structure at the bottom of the traditional blender main unit causes the motor temperature to rise too high, affecting the normal use of the equipment and reducing the life of the motor, posing a safety hazard.
The blender features a recirculating heat dissipation structure. The heat dissipation duct and the bottom plate separate the heat dissipation slot from the air inlet. The cooling fan at the bottom of the motor draws in cold air and cools it by flowing over the outside of the motor. Hot air is discharged through the heat dissipation chamber and duct, forming a good heat dissipation cycle and preventing hot air from being drawn in again.
It effectively reduces motor temperature rise, extends motor life, ensures stable motor operation at high speeds, and avoids safety hazards.

Abstract
Description
Technical Field
[0001] This application relates to the field of blender technology, and more specifically to a blender main unit structure with recirculating heat dissipation. Background Technology
[0002] As a modern kitchen appliance that integrates multiple functions, the high-speed motor, the core power component of a blender, needs to maintain an ultra-high speed of over 22,000 rpm for extended periods. During continuous operation, the internal coil windings and bearing system of the motor generate a large amount of heat. If effective heat dissipation is not achieved, the motor temperature will directly exceed the safety threshold, causing problems such as aging of insulation materials and deterioration of electromagnetic performance. In severe cases, this may lead to equipment failure or even safety hazards.
[0003] Traditional blenders typically employ a bottom-mounted centralized heat dissipation design, where both the cooling air inlet and outlet are located in adjacent areas at the bottom of the main unit. This design reveals significant drawbacks in actual operation: when the cooling fan is running, the high-temperature airflow exhausted from the outlet is prone to localized heat circulation due to the limited space at the bottom. Some of the exhausted hot air is then drawn back into the machine through the adjacent air inlet, affecting the cooling of the motor inside the blender. This leads to excessively high motor temperatures during prolonged operation, impacting the blender's normal operation and reducing motor lifespan. Utility Model Content
