Description

Technical Field

[0001] This utility model relates to the technical field of smoothie machine equipment, specifically to a refrigeration tank with a rotating shaft dynamic seal. Background Technology

[0002] A smoothie maker, also known as a slush machine or a cold drink machine, is a small electrical appliance used to make smoothies. The main structure of a smoothie maker includes the main body, a refrigeration system, and a control system. The main body houses a motor housing and a refrigeration tank. The motor housing contains the motor and an electrical control box, and the motor's drive shaft runs through the refrigeration tank.

[0003] In some existing technologies, temperature sensors are usually installed on the refrigeration tank to facilitate the detection of working temperature or operating temperature. This allows for effective temperature detection and feedback of data or information to the control structure within the equipment, thus enabling the control of the refrigeration tank's operation.

[0004] While the above-mentioned technical solution achieves the detection and feedback of working temperature or operating temperature to a certain extent, the overall sealing performance of the structure is reduced after the temperature sensor is installed and the sealing structure is adapted. This is due to factors such as structural assembly, structural gaps, and sealing performance, which may lead to leakage in severe cases and affect the detection accuracy of the temperature sensor. Therefore, the overall structure needs further optimization and improvement to enhance its sealing performance and reduce the risk of leakage. Utility Model Content
