Description

A convenient and easy-to-use split vacuum preservation machine Technical Field

[0001] This utility model relates to the field of vacuum preservation technology, and more specifically to a convenient-to-operate detachable vacuum preservation machine. Background Technology

[0002] A vacuum preservation machine, also known as a vacuum sealing machine, is a device that uses a vacuuming component to create a vacuum in food storage containers such as food storage bags and boxes, and then seals the bag opening to prevent the food inside the vacuum-packed bag from oxidizing or spoiling due to contact with air. It can effectively inhibit the growth of various bacteria and molds, thereby extending the shelf life.

[0003] To adapt to the diversity of food preservation containers on the market, the applicant has provided a Chinese utility model patent with authorization announcement number CN215323479U for a detachable vacuum food preservation machine. This utility model adopts a detachable structural design, with the vacuuming mechanism set in a detachable handheld device. The handheld device can be used in conjunction with the food preservation machine base to vacuum and seal food preservation bags, or it can be used alone to vacuum other food preservation containers such as food preservation boxes and bottles. It is flexible and versatile in use, thus solving the problem of the diversity of food preservation containers.

[0004] However, after its market launch, the applicant discovered two problems with this detachable vacuum preservation machine. First, the handheld unit is mounted in a horizontal, side-insertion manner using a mounting slot on one side of the base. This method requires force to push the handheld unit out during disassembly. Considering the feel and overall appearance of the machine, a push handle is typically not provided on the handheld unit, making disassembly relatively inconvenient and resulting in a poor user experience. Second, the handheld unit connects via an air suction nozzle and a recessed area within the mounting slot, which results in poor airtightness and a tendency for air leakage. Utility Model Content
