Vacuum Suction Nozzle Structure for Leak-Resistant VIP Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum suction apparatuses face challenges in forming and maintaining a high vacuum state within vacuum insulation panels and vacuum pouches due to leaks at the nozzle interface, which affects insulation efficiency and production costs.
Innovation Solution
A vacuum suction apparatus with a nozzle design featuring a suction portion, blade portion, and protrusion portion that minimizes leak size by optimizing the geometry and arrangement of these components to efficiently suction air from the interior of vacuum insulation panels and pouches, including a specific configuration of blade and protrusion elements to reduce separation distances and angles for improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional vacuum suction apparatus is used to suction air from the interior of a vacuum insulation panel, then air suction capability is provided, but leaks easily occur between the suction nozzle and the vacuum insulation panel making it difficult to form a vacuum
Solution Approach 1:
The nozzle is divided into multiple functional segments: a suction portion for air removal, blade portions for sealing and compression, and protrusion portions for positioning. This segmentation allows each component to perform its specific function optimally, with blade portions creating multiple contact points with the vacuum insulation panel to prevent leakage while the suction portion maintains air suction capability.
Solution Approach 2:
The blade portions act as intermediary elements between the suction nozzle and the vacuum insulation panel. These blade portions make contact with and compress the outer skin material of the vacuum insulation panel, creating a sealing interface that prevents leakage while allowing the suction portion to effectively remove air from the interior.
2Ease of manufacture
If the nozzle structure is simplified for ease of manufacture, then manufacturing cost is reduced, but sealing performance deteriorates leading to increased leakage
Solution Approach 1:
The nozzle integrates multiple functions into a single unified structure: the suction portion, blade portions, and protrusion portions are formed as one integrated component. This merging allows the nozzle to provide air suction, sealing, and positioning functions simultaneously without requiring multiple separate parts, thereby maintaining ease of manufacture while achieving effective leakage prevention through the coordinated action of its integrated components.

AI summary
Disclosed are a vacuum suction nozzle for improving vacuum suction performance and a vacuum suction apparatus including the same. The nozzle includes blade portions extending from both sides thereof so as to reduce a gap occurring between the nozzle and an outer skin material for a vacuum insulation panel (VIP) or other vacuum wrapping paper when the outer skin material or vacuum wrapping paper is sealed, thereby minimizing the occurrence of a leak and thus enabling efficient vacuum suction. Further, the nozzle achieves efficient vacuum suctioning by ensuring a suction channel inside the vacuum insulation panel (VIP) or other vacuum wrapping paper through a protrusion extending to the front of the nozzle.
