VACUUM COVER CONNECTABLE TO VACUUM PUMP

Description

TECHNICAL FIELD

The present utility model pertains to the technical field of vacuum covers, specifically to a vacuum cover connectable to a vacuum pump.

BACKGROUND ART

As is well known, the primary function of a vacuum pump is to extract air from a container to create a vacuum environment, which is widely applied in scenarios such as food preservation and item storage. However, existing vacuum pumps often suffer from poor compatibility: their fixed interface specifications make it difficult to achieve a precise match with containers of various shapes and sizes available on the market (such as glass jars, plastic containers, insulated cups, etc.). The resulting gaps during connection can cause air leakage, which not only compromises the vacuum effect but also necessitates additional adapter accessories. This leads to cumbersome operation and significantly reduced practicality. To address this pain point, the present utility model proposes a vacuum cover connectable to a vacuum pump. By adopting a modular design featuring a dedicated cover and a body, it achieves flexible adaptation to various containers, thereby effectively solving the problem of poor compatibility in existing equipment and enhancing ease of use and practicality.

DETAILED DESCRIPTION OF THE UTILITY MODE

The technical solutions in the embodiments of the present utility model are described clearly and comprehensively below with reference to the accompanying drawings. It is evident that the described embodiments represent only a portion of the embodiments of the present utility model, not all of them. All other embodiments obtained by persons of ordinary skill in the art without creative efforts based on the embodiments of this utility model shall fall within its protection scope.

Referring to FIGS. 1-4, a vacuum cover connectable to a vacuum pump comprises a body (1), a docking port (2), and a cover (3). The docking port (2) is positioned at the bottom of the body (1). The body (1) houses a vacuum pump, a mainboard, and a lithium battery. The top of the body (1) is equipped with a control button electrically connected to the mainboard. The bottom of the cover (3) features a silicone gasket (5). The cover (3) includes a silicone plug (4), and the silicone plug (4) matches the docking port (2).

In this embodiment, the lithium battery inside the body (1) powers the entire device, ensuring stable operation of components such as the vacuum pump and mainboard. During use, first press the entire silicone gasket (5) at the bottom of the cover (3) firmly against the rim of an external container. The silicone's elastic deformation creates an initial seal. Then, precisely align the docking port (2) at the bottom of the body (1) with the silicone plug (4) on the cover (3), causing the silicone plug (4) to engage within the docking port (2) to establish an air passage connection. Subsequently, press the control button on the top of the body (1). Upon receiving the command, the mainboard activates the vacuum pump. Air is extracted from the container through the channel formed by the docking port (2) and the silicone plug (4). When the preset vacuum level is achieved, the vacuum pump automatically ceases operation. At this point, the silicone plug (4), due to the internal pressure difference, tightly adheres to the through-hole of the cover (3), effectively sealing the air passage. Simultaneously, the silicone gasket (5) at the bottom of the cover (3) is pressed tightly against the container rim, forming a secondary seal. This dual-sealing structure ensures the container interior maintains a stable vacuum state over an extended period.

To enhance the overall functionality of the cover (3) and body (1), both the cover (3) and body (1) are made of plastic material in this embodiment. Plastic is lightweight, reducing the device's overall weight and facilitating one-handed operation or portability for the user. Furthermore, it exhibits good chemical stability and withstands minor impacts and friction from daily use, thereby minimizing damage caused by knocks. Additionally, plastic material has low processing and molding difficulty, enabling precise matching of the structural dimensions of the cover (3) and body (1). This ensures effective sealing when the docking port (2) and silicone plug (4) are connected, preventing air leaks during the vacuum pumping process. This material choice balances practicality and economy while maintaining structural strength, effectively enhancing the durability and operational convenience of the device.

To improve the connection sealing performance between the cover (3) and the container rim to prevent air leakage during the vacuum process, the silicone gasket (5) is fixedly connected to the bottom of the cover (3) in this embodiment (e.g., by bonding or integrated injection molding). This connection method allows the silicone gasket (5) and cover (3) to form a stable whole, preventing the silicone gasket (5) from shifting or detaching during use, which could affect the sealing performance. The silicone gasket (5) possesses good elasticity and ductility. Once fixed in place, it closely conforms to the rims of containers of different specifications along with the cover (3), filling gaps through its own deformation. During vacuum pumping, the pressure difference between inside and outside further enhances this conformity, effectively preventing air infiltration. This ensures reliable sealing to maintain a stable vacuum environment inside the container. It also extends the service life of the silicone gasket (5), reducing the need for frequent replacement due to loosening.

To enhance the anti-slip performance during operation and prevent slippage that could affect docking accuracy or operational stability when holding the body (1), the outer wall of the body (1) is specifically provided with multiple non-slip ribs in this embodiment. These non-slip ribs are arranged in a regular pattern of raised and recessed strips, working in conjunction with the plastic material of the body (1). When the user grips the body (1), the non-slip ribs increase the contact area between the palm and the outer wall of the body, while the gaps between the ribs help channel hand sweat, reducing the risk of slipping in humid environments. Whether aligning precisely with the cover (3) or while holding the device steady during the vacuum process, the non-slip ribs enhance grip friction. This ensures the user can firmly control the body (1), minimizing the risk of operational errors or device drops caused by hand slippage, thereby enhancing overall safety and convenience of use.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
