CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of Chinese Patent Application No. 202320823839.X filed on Apr. 13, 2023, the contents of which are incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The present application relates to the technical field of vacuum sealers, in particular to a portable vacuum sealer.

BACKGROUND OF THE INVENTION

A traditional vacuum sealer feeds the bag from one side, so that only one vacuum packaging bag may be vacuumed and sealed at one time, thus the efficiency of vacuuming and sealing is low, thereby the function of vacuuming and sealing both sides may not be realized. Accordingly, Patent Publication No. CN217836298U discloses a mobile dual-side vacuum sealer comprising a main body as well as a base, wherein a suspension assembly is provided at the bottom of the main body, and the base is detachably connected to the main body by the suspension assembly. In such a setup, both sides of the bottom of the main body may be fed into the bag, that is, two bags may be vacuumed and sealed at one time, which significantly improves the working efficiency.

However, since the main body needs to be pressed manually from top to bottom during each vacuuming and sealing, the consumer's hands may not be freed, which is a waste of time and effort, thereby significantly reducing the packaging efficiency.

SUMMARY OF THE INVENTION

In order to overcome the defects mentioned above in the prior art, provided in the present application is a portable vacuum sealer. While vacuuming, the base and the main body may be driven to move towards each other to achieve vacuuming and sealing, which frees the consumer's hands, thereby improving packaging efficiency.

The technical solutions adopted in the present application to solve the problems are as follows:

A portable vacuum sealer includes:

    • a main body, including a housing with an internal chamber, a vacuum pump provided in the chamber, and an airbag inserted in the bottom of the housing, in which a suction nozzle is provided on the airbag, and the vacuum pump is connected to the suction nozzle through a suction tube; and
    • a base, provided below the main body and detachably connected to the airbag by an engaging structure,
    • in which the airbag shrinks to drive the base to move toward a bottom of the housing by the engaging structure when the vacuum pump is activated.

Adopting the portable vacuum sealer in the present application, the base is detachably connected to the main body through an engaging structure between the base and the airbag, which is simple and convenient, thereby facilitating the consumer to clean up the food remnants after vacuuming when the base is separated from the main body. Additionally, the airbag shrinks upwards to drive the base simultaneously to move upwards so as to abut the bottom of the main body when the vacuum pump is activated, so that a manual squeeze is no longer required, which frees the consumer's hands, thereby improving the packaging efficiency.

Further, the engaging structure includes a snap block and a snap hole snap-fitted with each other, in which one of the airbag and the base is provided with the snap block, another one of the airbag and the base is provided with the snap hole; and a concave chamber is provided on the base for avoiding and accommodating the airbag.

Further, a vacuum hole is provided on the bottom of the housing, in which the vacuum hole is connected to the vacuum pump through the suction tube; and the vacuum hole is communicated with the concave chamber so that the concave chamber is formed as a vacuum chamber when the snap block is snap-fitted with the snap hole.

Further, a sealing strip is provided on the bottom of the housing and/or at a top of the base; when the airbag shrinks to drive the base to move toward the bottom of the housing until the sealing strip is squeezed, the concave chamber is sealed to form as a sealed vacuum chamber.

In such a setup, when the base moves close to the bottom of the main body until the scaling strip is squeezed, the concave chamber is sealed around to form a vacuum chamber; when the vacuum chamber does not leak, the vacuum chamber gradually forms negative pressure due to the vacuum pump continuously providing suction; when the pressure inside the vacuum chamber is less than the exterior atmospheric pressure, a pressure difference may be formed at the base, so that the base may further be fully close to and abut the main body, thereby better realizing vacuuming and scaling.

Further, a first magnetic part is provided on the airbag, and a second magnetic part is provided on the base at a position corresponding to the first magnetic part; the first magnetic part is aligned and attracted to the second magnetic part when the base is snap-fitted with the airbag.

In such a setup, provided are a first magnetic part and a second magnetic part attracted to each other; after the snap block is inserted into the snap hole, the assembly is completed by simply paralleled pushing the base until the first magnetic part is attracted to the second magnetic part; therefore, the first magnetic part and the second magnetic part play a role of rapid positioning, which significantly improves the efficiency of assembly; and the connecting firmness between the base and the main body further increases after the first magnetic part is attracted to the second magnetic part.

Further, the snap block is an inverted L-shaped structure and includes a horizontal segment and a vertical segment, in which the horizontal segment is inserted into the snap hole, in which a plurality of reinforcing ribs is provided on an exterior side of the vertical segment.

Further, the housing includes an exterior housing and a sealing cap provided on a bottom of the exterior housing, in which the exterior housing is connected to the sealing cap to form the internal chamber; the airbag is inserted onto the sealing cap.

Further, heating parts are provided on a front side and a rear side of the airbag on the sealing cap, in which the heating parts are elongated heating sheets.

Further, the internal chamber is further provided with a circuit board and a power supply battery; the vacuum pump is connected to the circuit board and the power supply battery respectively.

Further, the housing is further provided with a charging port for charging the power supply battery.

In summary, the portable vacuum sealer of the present application has the advantages as follows:

Adopting the portable vacuum sealer in the present application, the base is detachably connected to the main body through an engaging structure between the base and the airbag, which is simple and convenient, thereby facilitating the consumer to clean up the food remnants after vacuuming when the base is separated from the main body. Additionally, the airbag shrinks upwards to drive the base simultaneously to move upwards so as to abut the bottom of the main body when the vacuum pump is activated, so that a manual squeeze is no longer required, which frees the consumer's hands, thereby improving the packaging efficiency.

Adopting the portable vacuum sealer in the present application, when the base moves close to the bottom of the main body until the sealing strip is squeezed, the concave chamber is sealed around to form a sealed vacuum chamber; when the vacuum chamber does not leak, the vacuum chamber gradually forms negative pressure due to the vacuum pump continuously providing suction; when the pressure inside the vacuum chamber is less than the exterior atmospheric pressure, a pressure difference may be formed at the base, so that the base may further be fully close to and abut the main body, thereby better realizing vacuuming and sealing.

Adopting the portable vacuum sealer in the present application, provided are a first magnetic part and a second magnetic part attracted to each other; after the snap block is inserted into the snap hole, the assembly is completed by simply paralleled pushing the base until the first magnetic part is attracted to the second magnetic part; therefore, the first magnetic part and the second magnetic part play a role of rapid positioning, which significantly improves the efficiency of assembly; and the connecting firmness between the base and the main body further increases after the first magnetic part is attracted to the second magnetic part.

Referring to FIG. 1-7, provided in the present application is a portable vacuum sealer, including a main body 1 and a base 2 detachably connected to the main body 1. Specifically, the main body 1 includes a housing 11; the housing 11 includes an exterior housing 111 and a scaling cap 112 detachably connected to the bottom of the exterior housing 111, in which the exterior housing 111 is connected to the sealing cap 112 to form the internal chamber; the internal chamber is provided with a vacuum pump (not shown in figures), a circuit board (not shown in figures), and a power supply battery (not shown in figures); and the vacuum pump is electrically connected to the circuit board and the power supply battery respectively.

In the present embodiment, a side of the sealing cap 112 is further provided with a charging port 1122 for charging the power supply battery.

Referring to FIG. 3 and FIG. 4, airbags 12 are inserted onto both the left and right sides of the sealing cap 112; specifically, the airbag includes an airbag body 121 forming an air chamber, a top plate 122 provided on a top of the airbag body 121, and a bottom plate 123 provided on a bottom of the airbag body 121; the airbag 12 is mounted on the top of the sealing cap 112 by the top plate 122 and located in the internal chamber, in which the airbag body 121 and the bottom plate 123 is provided across the sealing cap 112; a suction nozzle 1221 connected to the air chamber of the airbag body 121 is provided on the top plate 122, in which the vacuum pump is connected to the suction nozzle 1221 by the suction tube (not shown in figures); and a snap hole 1231 is provided on the bottom plate 123. Additionally, a vacuum hole 1121 is provided on a middle part of the sealing cap 112, in which the vacuum hole 1121 is connected to the vacuum pump through the suction tube.

Referring to FIG. 2 and FIG. 6, a concave chamber 21 for accommodating the airbag 12 is provided on the base 2, in which both the left and right sides of the concave chamber 21 are provided with snap blocks 22 snap-fitted with the snap holes 1231. Specifically, the snap block 22 is an inverted L-shaped structure and includes a horizontal segment 221 and a vertical segment 222, in which the horizontal segment 221 is inserted into the snap hole 1231, in which a plurality of reinforcing ribs 223 is provided on an exterior side of the vertical segment 222 to increase the supporting strength of the snap block 22.

In such a setup, when assembling the base 2 and the main body 1, simply inserting the horizontal segment 221 on the snap block 22 into the snap hole 1231, which is simple and convenient, thereby facilitating the consumer to clean up the food remnants after vacuuming when the base 2 is separated from the main body 1.

In the present embodiment, provided are two airbags 2, which are located on both the left and right sides of the sealing cap 112 respectively, in which each airbag 12 is provided with two snap holes 1231 spaced apart; and both left and right sides of the concave chamber 21 is provided with two snap blocks 22 snap-fitted with the snap holes 1231, in which two snap blocks 22 are connected to each other by a connecting block 23 and fixed in the concave chamber 21.

When vacuuming a packaging bag, placing the opening side of the packaging bag on the base 2 located below the main body 1, and subsequently activating the vacuum pump; the vacuum pump may draw the air from the airbag 12 so that the airbag 12 shrinks; since the airbag 12 is snap-fitted to the base 2 by the snap block 22 and the snap hole 1231, when the airbag 12 shrinks and moves upwards, the airbag 12 synchronously drives the base 2 close to the bottom of the housing 11, and the concave chamber 21 on the base 2 is communicated with the vacuum hole 1121 on the sealing cap 112, in which the vacuum pump may draw air out of the concave chamber 21 so that a vacuum chamber is formed, thereby realizing vacuuming of the packaging bag.

In such a setup, by providing a snap hole 1231 on the airbag 12, the airbag 12 shrinks upwards to drive the base 2 simultaneously to move upwards so as to abut the bottom of the main body 1 when the vacuum pump is activated, so that a manual squeeze is no longer required, which frees the consumer's hands, thereby improving the packaging efficiency.

It is to be noted that, in other embodiments, the positions of the snap hole 1231 and the snap block 22 may also be switched, that is, the snap hole 1231 is provided in the concave chamber 21 of the base 2, while the snap block 22 is provided on the airbag 12, which may also achieve the same technical effect and is not limited herein.

Referring to FIG. 5, heating parts are provided on a front side and a rear side of the airbag 12 on the sealing cap 112; preferably, the heating parts are elongated heating sheets 14. In such a setup, the airbag 12 shrinks and drives the base 2 to move upwards until the heating sheets 14 touches to the opening of the packaging bag so that the packaging bag may be sealed.

Further, a first scaling strip 13 is provided on the sealing cap 112, in which the first scaling strip is annular in shape and surrounds the outside of the airbag 12; similarly, a second sealing strip 24 corresponding to the first sealing strip 13 is provided on an upper side of the base 2, in which the second sealing strip 24 is also annular in shape and surrounds the outside of the concave chamber 21; in such a setup, when the airbag 12 shrinks and drives the base 2 to move upwards until the first sealing strip 13 abuts the second sealing strip 24, then concave chamber 21 is scaled to form a sealed vacuum chamber.

In such a setup, when the vacuum chamber does not leak, the vacuum chamber gradually forms negative pressure due to the vacuum pump continuously providing suction; when the pressure inside the vacuum chamber is less than the exterior atmospheric pressure, a pressure difference may be formed at the base 2, so that the base 2 may further be fully close to and abut the main body 1, thereby better realizing vacuuming and scaling.

Of course, in the other embodiments, there may be only one first sealing strip 13 or only one second sealing strip 24, which is not limited herein.

Additionally, in order to further improve the assembling efficiency between the base 2 and the main body 1, two sides of the snap hole 1231 on the bottom plate 123 of the airbag 12 are provided with first magnetic parts (not shown in figures), while two sides of the snap block 22 in the concave chamber 21 are provided with second magnetic parts (not shown in figures); preferably, the first magnetic part and the second magnetic part are both magnets; when the snap block 22 is snap-fitted with the snap hole 1231, the first magnetic part is aligned and attracted to the second magnetic part. In such a setup, provided are a first magnetic part and a second magnetic part attracted to each other; after the snap block 22 is inserted into the snap hole 1231, the assembly is completed by simply pushing the base 2 in parallel until the first magnetic part is attracted to the second magnetic part; similarly, when disassembling, simply pushing the base 2 out in parallel. It is clear that the first magnetic part and the second magnetic part play a role of rapid positioning, which significantly improves the efficiency of assembly; and the connecting firmness between the base 2 and the main body 1 further increases after the first magnetic part is attracted to the second magnetic part.

In summary, the portable vacuum sealer provided in the present application has advantages as follows:
