Background technique

Vacuum packaging machines are gradually recognized by consumers in applications such as food preservation and item storage. In related civil applications, manufacturers provide the following two forms of products according to different needs:

1. Hand-held vacuum pump: equipped with a small suction nozzle (mostly cylindrical) connected to the vacuumed container, and sealed with the connection port of the lunch box, storage bag and other containers with a one-way valve type suction port , Air is sucked away from the suction nozzle by electric or manual means, and a vacuum environment is created in the vacuumed device. In this application, the container being evacuated has a one-way valve-style suction port and is reusable.

2. Desktop vacuum packaging machine: It is used to extract vacuum from storage bags without one-way valve-type air outlet, and heat seal the mouth. Since the opening of the storage bag is elongated, an elongated connecting port is required to be docked with it. Therefore, these devices are all designed as desktop structures, similar to printers in appearance. In this application, the container to be vacuumed does not have a one-way valve type suction port, and relies on heat sealing to maintain the vacuum after reaching the vacuum level, which is a one-time application.

In household or commercial use, reusable containers with a one-way valve type air extraction port and disposable containers without a one-way valve type air extraction port are used. In order to meet the needs, different special air extraction devices need to be equipped, and repeated investment , and occupy storage space.

When vacuum packaging cooked food items, most of the juice is drawn out and enters the air path of the vacuum packaging machine with the airflow. Since these air passages cannot be disassembled for cleaning, mildew will inevitably form in the air passages over time, which may cause blockage of the air passages in the slightest, and rust in severe cases, resulting in equipment damage. The relevant design cannot effectively avoid such situations, or although it can prevent the juice from entering the gas path, it is inconvenient to clean and the user experience is poor.

Lay the mouth of the disposable plastic packaging bag to be vacuumed to the opening end of the detachable waste storage box 3, use the pressing cover 5 to press and fix the mouth of the packaging bag, and use the hand-held air extractor 1 Negative pressure is generated to extract the air inside the disposable packaging bag from the detachable waste storage box 3. During this process, the juice, particles and corrosive substances inside the packaging bag are sucked into the detachable waste storage box 3 is temporarily stored inside to prevent it from entering the communication air path between the hand-held air extractor 1 and the detachable waste storage box 3. After vacuuming is completed, remove the detachable waste storage box 3 and put Just pour out the juice, particles and corrosive substances inside it.

In the embodiment of this application, the application adopts the "two-piece split type" design, and the whole device is divided into two parts: a hand-held air extractor and a heat-sealing connection table, and the hand-held air extractor can be independent of the heat-sealing joint. The barge is separately connected to the container with the one-way valve type suction port to complete the operation of vacuuming the container; while the holding type air pump is connected to the heat-sealing connection table, it can also complete the pumping without the one-way valve type. The air-tipped disposable bag is vacuumed and heat-sealed. The design realizes one machine with two functions, low cost and flexible use.

Please refer to Fig. 3 and Fig. 4, in one embodiment, the detachable waste storage box 3 includes a box body 31, a waste storage chamber 34 is arranged inside the box body 31, and an air guide column 36 is arranged in the waste storage chamber 34, The air guide column 36 is provided with an air guide hole 37 inside, and the heat-sealing connection platform includes a pedestal 2, an air extractor docking seat 201 is arranged on one side of the pedestal 2, and an air nozzle connection port 202 is arranged on the inner side of the air extractor docking seat 201, and the pedestal 2.
