Description

Technical Field

[0001] The utility model relates to the technical field of vacuum fresh-keeping machines, and more specifically refers to a separation type vacuum fresh-keeping machine which is convenient to operate. Background Art

[0002] A vacuum fresh-keeping machine, also known as a vacuum sealing machine, is a machine that uses a vacuum pump to draw vacuum from fresh-keeping bags, fresh-keeping boxes and other fresh-keeping containers, and then seals the bag openings to prevent the food in the vacuum-packed bags from oxidizing or deteriorating due to contact with air. It can effectively inhibit the growth of various bacteria and molds, thereby extending the shelf life.

[0003] In order to adapt to the diversity of fresh-keeping containers on the market, the applicant has provided a Chinese utility model patent with authorization announcement number CN215323479U, which is a separate vacuum fresh-keeping machine. The utility model adopts a separate structural design and sets the vacuuming mechanism in a detachable handheld machine. The handheld machine can be used in conjunction with the fresh-keeping machine base to vacuum and seal the fresh-keeping bags, and can also be used alone to vacuum other fresh-keeping containers such as fresh-keeping boxes and fresh-keeping bottles. It is flexible and diverse in use, thus solving the problem of diversity of fresh-keeping containers.

[0004] However, after being put on the market, the applicant found that the detachable vacuum fresh-keeping machine still has two problems. First, the handheld device is installed in the mounting groove by horizontal side insertion in a mounting groove by setting a mounting groove on one side of the base. This method requires the handheld device to be pushed out forcefully when it is separated and disassembled. However, considering the handheld feel and the appearance of the whole machine, the handheld device is usually not provided with an additional push handle, which makes the disassembly and separation of the handheld device relatively inconvenient and the operating experience is poor. Second, the handheld device is docked by the exhaust nozzle and the recessed part in the mounting groove, which has poor air tightness and is prone to air leakage. Utility Model Content
