Integrated Drive Body System for Cold Beverage Makers

This comprehensive drive body design improves cold beverage maker assembly, safety, and functionality through integrated engineering that eliminates traditional fastening methods. The system features modular components with intuitive docking mechanisms that ensure stable operation while simplifying manufacturing and enabling convenient maintenance without tool requirements.

The Problem

Conventional cold beverage makers, particularly smoothie makers and frozen drink dispensers, use traditional screw connections to attach the evaporator cooling apparatus to the main housing. These screw-based designs present multiple challenges: long-term use causes evaporator sagging due to component weight, creating gaps and poor sealing at junction points. The ice-making chamber can detach from the evaporator during use, presenting safety hazards when rotating components are exposed. Copper tubing required for cooling creates excessive weight concentrated in the evaporator assembly, exacerbating structural stress. Assembly and disassembly for cleaning require tools and significant time, reducing practical usability for commercial food service applications. Users and operators desire a more elegant solution that ensures structural stability, improves safety, and simplifies maintenance without sacrificing cooling performance.

What This Invention Does

The drive body integrates a housing design featuring a head portion for mounting the cooling evaporator and a control portion for mounting operational electronics. The evaporator connects through a docking mechanism rather than threaded fasteners, with an end cover groove precisely engineered to receive the evaporator end cover. A sealing ring and docking ring assembly create an airtight connection between the evaporator and ice-making chamber, preventing leakage and ensuring efficient cooling. Support ribs and limiting holes in the bearing insertion post distribute the evaporator’s weight effectively, preventing sagging and deformation. An innovative pull-connection system using elastic connecting strips with conical heads provides both preliminary location stability and permanent secure attachment, eliminating loose connections while simplifying assembly. The design enables tool-free installation and removal for cleaning while maintaining structural integrity.

Key Features

• Modular Docking Architecture. The evaporator docks into the drive housing through a designed mechanism rather than threaded connections, enabling quick disconnection for cleaning without tools.
• Integrated Weight Support. Bearing insertion posts with transverse and longitudinal support ribs distribute evaporator weight across multiple support points, preventing sagging and deformation in long-term use.
• Tool-Free Assembly. Elastic connecting strips with conical heads provide secure temporary mounting for initial alignment, followed by threaded final fastening – simplifying assembly workflows and enabling operators to perform maintenance without tool requirements.
• Sealed Cooling Integration. The sealing groove and docking ring assembly create reliable airtight connections between the evaporator and ice-making chamber, ensuring efficient cooling performance and preventing product contamination.
• Safety-Enhanced Design. The ice-making chamber remains securely attached during operation through multiple connection points, eliminating detachment hazards and enabling operators to focus on food preparation tasks.

Who Is Behind It?

Guangzhou Xin’an Trading Co., Ltd., a Chinese appliance manufacturer, developed this innovation with inventor Zhou Quan. PATENTS AU PTY LTD managed the patent application from Melbourne, Australia.

Why It Matters

The global cold beverage and frozen drink market represents billions of dollars annually, with growth driven by expanding consumer demand and proliferation of beverage customization options. Commercial operators and home users alike demand equipment that performs reliably, maintains food safety standards, and requires minimal maintenance downtime. Current designs require frequent servicing and present potential safety issues that concern operators. This integrated drive body design represents a genuine advancement in beverage equipment engineering, supporting both safety and operational efficiency. The technology aligns with modern manufacturing trends favoring modular, service-friendly designs that reduce lifecycle costs and support sustainable equipment life. As food service operators increasingly demand equipment reliability and simplified maintenance, beverage makers featuring this drive body design offer competitive advantages in commercial markets.

Related Concepts

Modular design in commercial appliances enables faster assembly and easier maintenance, reducing the total cost of ownership across a product’s lifecycle. In food service equipment, food safety regulations require quick-disassembly components to facilitate thorough cleaning, making tool-free docking systems especially valuable.

The refrigeration cycle in cold beverage machines depends on a well-sealed evaporator circuit – poor sealing causes performance degradation and contamination risk. Advances in fastener-free assembly reduce mechanical stress points and improve long-term reliability in high-use commercial environments.
