Storage container for vacuum blender with backflow prevention function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum blenders face the challenge of food materials flowing backward through the sealing cover during the vacuum process, which can lead to contamination of the vacuum motor and other components, and accelerate nutrient destruction and oxidation of food fibers.
Innovation Solution
A storage container with a backflow prevention function is designed, featuring a floating valve member at the lower portion of the sealing cover that rises by buoyancy to seal the air passage, preventing fine food matters from flowing backward through the check valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vacuum blender is used to crush food materials, then the crushing efficiency and nutrient preservation are improved, but fine food matters and bubbles flow backward through the sealing cover to contaminate the vacuum motor and components
Solution Approach 1:
A floating valve member is introduced as an intermediary component between the crushing chamber and the vacuum motor. This valve member rises with the bubbles to seal the air passage, preventing fine food matters from reaching the motor while allowing the vacuum process to continue efficiently
Solution Approach 2:
The harmful backflow function is extracted and separated from the main vacuum system by placing the floating valve member at the sealing cover. This isolates the contamination risk from the vacuum motor and other sensitive components
2Object-generated harmful factors
If a check valve is installed to prevent backflow, then contamination is reduced, but the vacuum state cannot be maintained and air enters the container
Solution Approach 1:
The floating valve member is designed to be dynamic rather than fixed. It automatically adjusts its position based on the bubble level, rising to seal the passage when bubbles are present and falling to allow normal vacuum operation, thus maintaining both protection and vacuum integrity
Solution Approach 2:
The floating valve member is self-actuating through buoyancy forces. It automatically responds to the presence of bubbles without external control, sealing the passage when needed and opening when not needed, maintaining the vacuum state through self-service operation

AI summary
The objective of the present invention is to provide a storage container for a vacuum blender having a backflow prevention function, which is configured such that a floating valve member is installed at a lower part of a sealing lid for covering the storage container for the vacuum blender, and when micronized foodstuffs, such as foam, rise in the process of creating a vacuum in the storage container, the floating valve member rises together by means of buoyancy of the micronized foodstuffs to hermetically seal an air passage, thereby preventing the micronized foodstuffs from flowing back out of the storage container. In order to achieve the above objective, the storage container for a vacuum blender having a backflow prevention function, according to the present invention, is a storage container used in a vacuum blender capable of processing foodstuffs in a vacuum state, and comprises: a container body which has an open upper portion and is provided with an inner space for storing foodstuffs; a sealing lid which covers the upper portion of the container body and has a check valve for blocking air from flowing into the inner space from the outside of the container body in a vacuum state; and a backflow preventing means which is installed at a lower portion of the sealing lid and has a floating valve member embedded therein to prevent micronized foodstuffs from flowing back out of the sealing lid through the check valve in such a manner that when the micronized foodstuffs rise, the floating valve member rises together by means of buoyancy to hermetically seal an air passage.
