Description

Technical Field

[0001] This utility model relates to the field of vacuum sealing machine technology, and in particular to a vacuum sealing machine that improves the tightness of the machine cover. Background Technology

[0002] A vacuum sealer is a device used to seal food, medicine, and other items. It works by removing air from the packaging, creating a low-oxygen environment that helps extend the shelf life of the goods and prevents oxidation and bacterial growth. Vacuum sealers are frequently used in homes, restaurants, and the food processing industry to maintain food freshness and extend its shelf life.

[0003] Currently, vacuum sealing machines consist of a main body and a cover that rotates and is mounted on the upper part of the main body. Before vacuuming, the cover needs to be locked to the main body so that the upper sealing ring of the cover presses against the lower sealing ring located on the outer edge of the vacuum groove. After the sealing operation is completed, the lock is automatically released. Existing locking structures often use a hook and a seat to achieve this, and the user usually needs to press the cover to connect the hook and the seat and lock the cover to the main body. However, the existing locking structure generates a lot of resistance when pressing, which requires a lot of force to press the cover. Long-term heavy pressing of the cover can damage the hook and seat, as well as the cover shell. Utility Model Content

[0017] This invention provides a lock seat and a limiting groove on the main body, and a matching connecting support, lock groove and lock hook assembly on the cover. When the cover is locked, the lock hook assembly can be securely hooked into the limiting groove, thereby achieving a tight fit between the cover and the main body. This structural design effectively improves the tightness of the lid, ensuring a good sealing environment between the upper and lower chambers during vacuuming, preventing air leakage, improving sealing quality, and helping to extend the shelf life of packaged goods. Traditional vacuum sealing machines require users to apply considerable force when pressing the lid, while this invention uses an electromagnetic valve to control the cylinder inflation, driving the locking hook assembly to lock and unlock, thus greatly reducing the resistance required to press the lid, alleviating the user's labor intensity, and making operation more effortless and convenient. It is especially suitable for long-term, high-frequency use scenarios, reducing excessive pressure on the hooks, seats, and lid shell, effectively avoiding damage to the hooks and seats and deformation of the lid shell caused by long-term heavy pressure. This not only improves the stability and reliability of the equipment but also extends its service life, reduces maintenance costs and replacement frequency, and saves users operating costs.
