Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum nozzles for packaging, specifically a retractable vacuum packaging vacuum nozzle device. Background Technology
[0002] Vacuum nozzles for packaging are key components specifically designed for various packaging applications to achieve vacuuming. They are typically installed on containers such as bags and boxes, serving as a channel for gas entry and exit. Generally made of durable plastics or rubber, they possess excellent sealing and abrasion resistance. Their ingenious design, sometimes incorporating a one-way valve, ensures that gas only exits during evacuation, effectively maintaining a vacuum within the packaging. Vacuum nozzles for packaging are widely used in the food, electronics, and precision instrument industries, extending shelf life, preventing oxidation and spoilage, and providing reliable protection for goods.
[0003] Existing vacuum nozzles for packaging have significant limitations in their structural design, with most being made of rigid materials with a fixed shape. These nozzles are typically straight, rigid tubes, lacking flexibility and adaptability, making them impossible to bend. When dealing with irregularly shaped or complex-shaped packages, they struggle to fit snugly against the surface, resulting in incomplete vacuuming. Furthermore, they lack telescopic functionality, failing to adjust their length according to package size, leading to poor applicability to different package dimensions and limiting their application range and vacuuming effectiveness.

[0005] Preferably, the air nozzle includes a flat air nozzle and a hollowed-out groove. The flat air nozzle has a through hollowed-out groove on its surface and is designed to be wider at the front and narrower at the back.
[0006] Preferably, the stretching plate includes a rigid rubber sleeve, a soft rubber sleeve, and a metal connector. The metal connector is fixedly connected to the rear end of the rigid rubber sleeve. The rigid rubber sleeve is provided in several groups, and adjacent groups of the rigid rubber sleeve are connected by a group of soft rubber sleeves.
[0007] Preferably, the air extraction structure includes an annular metal plate, a reinforcing base, and an air extraction rod, wherein the air extraction rod is fixed to the top of the reinforcing base, and the reinforcing base is fixedly connected to the top of the annular metal plate.
