At present, existing household storage boxes (such as pulley boxes, luggage, etc.) or storage boxes are just a conventional box body or box body, which only has the function of storing items. The objects or food stored in these boxes are easily damaged by the gnawing of insects and ants. At the same time, outside air and water vapor can enter the storage box, which is easy to cause moisture, mold, rot and oxidation of the items, resulting in the items or food. The storage time and shelf life are shorter. For this reason, some users put insect repellents, moisture repellants, etc. in the box, but the effect is not obvious, and it will also release peculiar smell and harmful gas, which is a safety problem.

Further, the ventilation hole, the silica gel sheet, the silica gel ring and the convex groove are arranged on the upper bottom surface of the top cover.

Further, it also includes a sealing gasket, and the sealing gasket is provided at the connection between the top cover and the box body.

Further, the hand-held vacuuming machine includes a casing, a vacuum pump and an air inlet, the air inlet is arranged at the bottom of the casing, and the vacuum pump is arranged inside the casing and is connected with the air inlet. holes are connected.

Further, the power supply device of the hand-held vacuum pump is a lithium battery, and the lithium battery is electrically connected to the vacuum pump, and the surface of the casing is provided with a key switch that controls the operation or stop of the vacuum pump.

Compared with the prior art, the beneficial effects of the present invention are:

The invention discloses a vacuum storage assembly. The air in the storage box is extracted by a hand-held vacuum pump. After the storage box becomes a vacuum, the silicone sheet is compressed to the ventilation hole of the storage box by atmospheric pressure, so that the The storage box can maintain a vacuum environment for a long time. It has anti-insect, anti-moisture, anti-mildew, anti-corrosion, anti-oxidation and fresh-keeping effects on the items or food stored in the storage box. It is very powerful and can effectively prolong the storage time and shelf life of the items or food. Simple structure, easy production and processing.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be combined arbitrarily to form new embodiments. .

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the present invention discloses a vacuum storage assembly, which includes a storage box and a hand-held vacuum machine 30 . The storage box includes a set of openable and closable top cover 10 and box body 13. There are buckles on both sides of the top cover 10. The buckles are buckled with the box body 13 to achieve an openable and closable connection. A sealing gasket 12 is provided. When the box body 13 is in a vacuum environment, the top cover 10 and the box body 13 are closely attached to the sealing gasket 12 due to the pressure of atmospheric pressure. The upper bottom surface of the top cover 10 is also provided with a ventilation hole 11, a circular convex groove 14, a silica gel sheet 21 and a silica gel ring 20. The silica gel ring 20 is provided with a groove 23 along the ring body. In the embedded connection, the silica gel sheet 21 is connected to the silica gel ring 20 along the circle center of the silica gel sheet 20 . The surface of the silica gel sheet 21 is provided with bumps 22 .

The hand-held vacuum pump 30 includes a casing 31 , a vacuum pump 32 and an air inlet 33 . The power supply device of the hand-held vacuum pump 30 is a lithium battery 34. The lithium battery 34 is electrically connected to the vacuum pump 32. The surface of the casing 31 is provided with a key switch 35 that controls the vacuum pump 32 to work or stop.

When the box body 13 is not evacuated, the silicone sheet 21 is separated from the vent hole 11. When the box body 13 needs to be evacuated to store food or articles, the hand-held vacuum machine 30 is attached to the bump 22, and the bump 22 makes The air inlet hole 33 is kept at a distance from the ventilation hole 11, which is beneficial for all the air inside the box body 13 to be drawn out. The working efficiency of the vacuum pump 32 is improved. The air in the box body 13 is drawn into the casing 31 by the vacuum pump 32 through the vent hole 11 and the air intake hole 33 and then discharged. When the box body 13 is completely evacuated, the pressure of the atmospheric pressure presses the silicone sheet 21 to the vent hole 11 , so that the outside air cannot flow into the box body 13 from the vent hole 11 . The items or food stored in the storage box in the vacuum environment can prevent insects, moisture, mildew, corrosion and oxidation, and play a role in keeping fresh.

The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. Scope of protection claimed.
