Description

A sealing assembly for an evaporator Technical Field

[0001] This utility model relates to the field of cold drink machine equipment technology, and in particular to a sealing component for an evaporator. Background Technology

[0002] A beverage cooler is a device specifically designed for making cold drinks, primarily composed of two core systems: a refrigeration system and a mixing system. The refrigeration system cools the ingredients, while the mixing system blends them to ensure even distribution. The evaporator is a crucial component of the refrigeration system, used to cool the materials to create a refreshing, snow-like beverage. During operation, one end of the rotating shaft is located outside the evaporator. To prevent leakage through the rotating shaft and avoid potential hygiene issues and safety risks, a sealing device is required between the rotating shaft and the evaporator.

[0003] However, current sealing devices between the rotating shaft and the evaporator have some shortcomings: they typically have only one seal, and this seal cannot self-compensate as it wears down during use. As the sealing performance gradually decreases, it may lead to material leakage, which in turn can cause mold growth inside the machine. In extreme cases, it may even cause a short circuit, posing a serious safety hazard.

[0004] Therefore, there is an urgent need to design a sealing assembly for the evaporator to solve the above problems.

The inner circumference of the fixing sleeve is provided with an inner bushing that abuts against the rotating shaft. The rear end of the inner shaft tube is embedded in the rear end of the evaporator shell, and the front end of the inner shaft tube abuts against the fixing sleeve.

[0008] As an improvement to the above solution, the rear end of the evaporator shell is provided with a rear end opening, and the rear end opening is provided with a rear end ring inside the evaporator shell. The rear end of the inner shaft tube is placed in the rear end ring and presses against the inner wall of the rear end opening.
