Mixing device and coffee machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing full-automatic coffee machines with Venturi structures face difficulties in thoroughly cleaning the milk conveying pipe, leading to health hazards and an inability to produce high-quality milk foam due to assembled gaps.
Innovation Solution
A mixing device with a design that forms a liquid conveying channel using a sealing strip and a Venturi structure without a traditional milk pipe, allowing for easy cleaning and integration of a complete Venturi structure to ensure high-quality milk foam production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional milk conveying pipe is used in the Venturi structure, then the device can be disassembled for cleaning, but the milk pipe cannot be thoroughly cleaned and assembled gaps prevent high-quality milk foam production
Solution Approach 1:
The patent removes the traditional milk conveying pipe from the Venturi structure and replaces it with a liquid conveying channel formed by a sealing strip directly joined to the enclosure wall. This extraction eliminates the separate milk pipe component that caused cleaning difficulties while maintaining the liquid conveying function through the integrated sealing strip design.
Solution Approach 2:
The patent merges the liquid conveying channel formation function into the sealing strip itself, which is detachably joined to the enclosure wall. The sealing strip integrates both the sealing function and the liquid conveying function, eliminating the need for a separate milk pipe and allowing thorough cleaning of the integrated channel.
2Ease of operation
If the Venturi structure is made detachable for cleaning, then cleaning access is improved, but assembled gaps prevent high-quality milk foam production
Solution Approach 1:
The patent extracts the separate milk pipe component and replaces it with an integrated liquid conveying channel formed by the sealing strip. This eliminates the need for additional assembly steps that create gaps, while the detachable sealing strip maintains cleaning accessibility.
3Adaptability or versatility
If a separate milk pipe is used for liquid conveyance, then the Venturi structure can be disassembled, but thorough cleaning becomes difficult leading to health hazards
Solution Approach 1:
The patent removes the separate milk pipe and replaces it with a liquid conveying channel formed by the sealing strip that is detachably joined to the enclosure wall. This maintains disassembly capability for cleaning while eliminating the hidden corners and complex structures of traditional pipes that prevent thorough cleaning.
Solution Approach 2:
The patent uses a flexible sealing strip to form the liquid conveying channel. The sealing strip can be easily detached and cleaned, and its flexible nature allows it to conform to the enclosure wall while providing a smooth, easy-to-clean surface without the rigid pipe structures that trap milk residue.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables convenient cleaning and production of high-quality milk foam, addressing the health hazards and quality issues associated with traditional Venturi structure-based coffee machines.
Implementation Method 1
the Venturi structure including a mixing cavity, a liquid inlet channel connected to the mixing cavity, a steam channel for connecting a steam source and an outlet channel for outputting, the steam channel and the outlet channel being connected to the mixing cavity

AI summary
A mixing device includes: a box body including a box bottom and an enclosure wall, the box bottom and the enclosure wall forming an accommodating cavity for holding liquid; a sealing strip, detachably joined to the enclosure wall to form a liquid conveying channel along a vertical direction between the enclosure wall and the sealing strip; and a Venturi structure separably disposed on a side of the box body. The liquid conveying channel is formed by joining the sealing strip to the box body, which solves a problem in that a traditional milk pipe is not easily cleaned, and a design without a milk pipe is combined with the complete Venturi structure, which ensures quality of the made milk foam, thereby meeting requirements of people for pursuing delicate mouthfeel and improving taste.
