This embodiment is for the purpose of describing the technical solution in a simple and clear manner. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The present invention is further described below in conjunction with specific drawings.

The vacuuming and the position of the sealing mechanism 2 are the same as those of a conventional household sealing machine, and will not be elaborated here; the sealing assembly and the sealing machine body 1 are connected by a press-type elastic self-locking mechanism 4; the above press-type elastic self-locking mechanism 4 has two states of locking and unlocking, which is locked by pressing and unlocked after pressing again; its structure has been widely used, and a vacuuming air inlet is provided in the vacuuming area 3. When the vacuuming area 3 is vacuumed, the sealing mechanism 2 will move downward, and the sealing mechanism 2 is a heating strip 21 provided on the sealing machine body 1 and a pressing strip 22 provided on the sealing assembly and matched with the heating strip 21. After the vacuuming area 3 is vacuumed, the heating strip 21 and the pressing strip 22 are pressed tightly for sealing. During vacuuming, the heating strip 21 is pre-pressed to the sealed bag, and after vacuuming is completed, the pressing strip 22 and the sealed bag are slowly pressed together as the sealing mechanism 2 moves downward. It should be noted that in the compressed state here, the vacuuming mechanism can flow from the sealed bag to the vacuuming area 3 during vacuuming. After vacuuming is completed, the controller controls the heating strip 21 to work to seal the bag opening, and then the vacuuming area 3 releases the sealing mechanism 2 and pops up. The pressing strip includes an elastic strip to provide flexible contact.

[0026] In this embodiment, the push-type elastic self-locking mechanism 4 is arranged on both sides of the slot 6 and the sealing component. However, this is only a preferred solution, and it can also be arranged in other areas, but the balance of the force on both sides is optimal.

[0034] It should be noted that, in this application, relational terms such as "first" and "second" are only used to distinguish one structure from another structure, and do not necessarily require or imply any such actual relationship between these structures. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the device including the elements.
