Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and more particularly to a connector assembly for air extraction and a connection structure for the connector assembly. Background Technology

[0002] As modern life places increasing demands on food hygiene and energy conservation, food is often stored in the refrigerator by wrapping it in plastic wrap. However, this method not only easily leads to moisture loss and flavor loss in food, but also results in a short shelf life and a large amount of discarded plastic wrap, which increases the cost of use and pollutes the ecological environment.

[0003] Vacuum sealing packaging has become an increasingly popular food storage solution in recent years. It can prevent the loss of moisture and flavor in food, extend the shelf life, and eliminate the need for single-use plastics, thus meeting environmental protection requirements.

[0004] However, the connector assembly of existing vacuum machines consists of an inner connector and an outer cover. When used alone, the inner connector is suitable for vacuuming dry foods, while the outer cover, when fitted onto the inner connector, is suitable for vacuuming wet foods. The inner connector has a first sealing ring on its downward-facing side, and the outer cover has a second sealing ring on its downward-facing side. Furthermore, a third sealing ring is required at the connection between the outer wall of the inner connector and the outer cover. The excessive number of sealing rings results in significant material waste. When switching between vacuuming dry and wet foods, the outer cover needs to be repeatedly disassembled and reassembled, making the operation cumbersome and inconvenient to use. Therefore, further improvements to the existing technology are necessary.

[0005] In addition, the housing of existing vacuum machines is mostly one-piece molded, which makes it inconvenient to fix the connector assembly to the housing. Therefore, further improvements to the existing technology are needed. Utility Model Content
