Solution Overview
Problem
Existing sealing devices are limited in their ability to simultaneously vacuum-seal both jars and compression bags, requiring separate devices for each application.
Innovation Solution
A versatile sealing device with a main machine and air duct that can accommodate different container sizes, featuring a vacuum pump, air extraction and inlet channels, and a control valve, along with a conversion structure for adapting to various container shapes and sizes, allowing for selective connection to both jars and compression bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sealing device is designed for a specific container type (jar or compression bag), then the sealing function is optimized for that type, but the device cannot seal other container types
Solution Approach 1:
The sealing device integrates multiple functions into a single device by incorporating both a jar sealing structure (with first sleeve joint part and first sealing gasket) and a compression bag sealing structure (with second sleeve joint part and second sealing gasket). The air duct can be selectively connected to accommodate different container types, allowing one device to perform multiple sealing functions without requiring separate specialized devices for jars and compression bags
Solution Approach 2:
The device is divided into modular components including a main machine, air duct, conversion structure, and different sealing gaskets. The air duct can be selectively connected or disconnected, and conversion structures can be attached or removed based on the container type being sealed. This segmentation allows the device to adapt to different sealing needs while maintaining a compact overall structure
2Productivity
If separate sealing devices are used for jars and compression bags, then each device is optimized for its specific function, but multiple devices are required increasing space and operational complexity
Solution Approach 1:
The patent merges the functionality of separate jar sealing devices and compression bag sealing devices into a single integrated sealing device. The main machine incorporates both a first sealing gasket for jar mouths and a second sealing gasket for compression bags, along with corresponding air extraction channels and air inlet channels. This consolidation eliminates the need for multiple separate devices, reducing space requirements and simplifying operational procedures while maintaining specialized sealing capabilities for each container type

Function Achieved in This Case
Enables efficient vacuum-sealing of both jars and compression bags using a single device, providing versatility and convenience by accommodating different container sizes and shapes through its adaptable design.
Implementation Method 1
A vacuum pump mounted to the housing and comprising an air extraction port. An air extraction channel defined in the housing and communicating the air extraction port with the first accommodating space.
Implementation Method 2
A control valve mounted to the housing and used for controlling open and close of the air inlet channel.

AI summary
A sealing device for sealing a cover on a mouth of a container, includes a main machine including a housing, a vacuum pump, an air extraction channel, an air inlet channel and a control valve for controlling open and close of the air inlet channel. The housing includes a sleeve joint part defining a first accommodating space adapted to the mouth. The vacuum pump is arranged in the housing and includes an air extraction port. The air extraction channel communicates the air extraction port with the first accommodating space and the air inlet channel communicates the first accommodating space with ambient air. The sealing device further includes an air duct which may be selectively connected to the housing and is respectively communicated with the air inlet channel and the air extraction channel. The sealing device can not only vacuum and seal jars, but also creates a vacuum in compression bags.
