[0024] A portable vacuum sealer includes a long strip heating module 3, a cover body 1, a base body 2 and a sealing ring 5. The sealing ring 5 is arranged between the cover body 1 and the base body 2 and together form a sealed cavity. The base body 2 is provided with a threading hole connected to the sealed cavity. The long strip heating module 3 includes a thermal insulation seat 31 and a heating strip 32. Through holes are provided at both ends of the thermal insulation seat 31, and conductive copper holes 33 are provided in the through holes. The ends of the heating strip 32 are pressed and fixed in the through holes by the conductive copper holes 33. The conductive copper holes 33 are connected to a wire (not shown in the figure).

[0025] like Figure 3 and 4 As shown, the conductive hole copper 33 in this embodiment can be made of a copper tube, and then clamped and fixed on the thermal insulation seat 31 by riveting. Before the copper tube is fixed, the end of the heating strip 32 is inserted into the through hole. When the copper tube is riveted, the heating strip 32 can be fixed in the through hole at the same time.

[0026] The thermal insulation seat 31 in this embodiment is made of phenolic resin, and may also be made of a ceramic substrate or Teflon.

[0027] The thermal insulation seat 31 has good mechanical properties and thermal stability, and the fixed heating strip 32 through the conductive copper hole 33 can be stably mounted on the thermal insulation seat 31. The entire long strip heating module 3 has a simple structure, and its back is neat and has no complex structure. When assembling, it only needs to be pasted on the seat body 2.

[0028] In this embodiment, a rubber sleeve 4 is preferably provided in the threading hole. The inner diameter of the rubber sleeve 4 is smaller than the outer diameter of the wire, and the wire passes through the rubber sleeve 4 .

[0030] In this embodiment, the wire is preferably welded to the conductive hole copper 33 .

[0031] Alternatively, the conductive wire is pressed and fixed in the through hole by the conductive hole copper 33 .

[0032] The two aforementioned methods can both fix the wire and the conductive hole copper 33 , as long as the contact between the two is stable.

[0033] like Figure 3 As shown, the threading hole is preferably located directly below the through hole in this embodiment. When the wire passes through the rubber sleeve 4, it can be basically straightened, which can fix the thermal insulation seat 31 and ensure that there is no extra wire under the thermal insulation seat 31.

[0034] like Figure 5 As shown, the sealing ring 5 preferably includes a sealing silicone 51 and a sealing silicone 52 in this embodiment. The sealing silicone 51 is located on the periphery of the sealing cavity. The sealing silicone 51 is located on the cover body 1 facing the long strip heating module 3. The sealing silicone 51 and the sealing silicone 52 are integrally formed.

[0035] The sealing silicone 51 is used to seal the sealing cavity when the cover body 1 and the base body 2 are put together, and the sealing silicone 52 cooperates with the long strip heating module 3 to realize the function of the pressure contact strip so that the opening of the vacuum bag is tightly attached to the heating strip 32.

[0036] like Figure 1 As shown, the pressure relief button is preferably installed above the base 2, side by side with the control button, so that the overall structure is more coordinated.
