Description

A storage box with a vacuum bag Technical Field

[0001] This utility model belongs to the field of storage technology, and in particular relates to a storage box with a vacuum bag. Background Technology

[0002] Vacuum bags, as a practical tool for modern home storage, have become a preferred solution for clothing storage due to their moisture-proof, dust-proof, and space-saving characteristics. Currently, most vacuum bags have air nozzles, requiring an external suction device for vacuuming. Different nozzles may require different models of external suction devices, which is inconvenient. Furthermore, existing vacuum bags have the following drawbacks: First, the lack of structural support makes the bag susceptible to puncture and damage from sharp objects during storage and transportation; second, the tight wrapping after degassing creates hard edges on the bag surface, hindering efficient stacking and posing a safety hazard; more importantly, long-term compressed storage causes irreversible deformation of the fabric fibers, leading users to report the need for ironing to restore the garment to its wearable state, which is inconvenient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, a storage box with a vacuum bag is provided that is convenient for vacuuming and easy to store without being easily damaged.

[0004] This utility model is achieved using the following technical solution: a storage box with a vacuum bag, comprising:

[0005] A top plate, a bottom plate, and a flexible bag body connecting the two, wherein the top plate and the bottom plate are respectively fixed to the upper and lower ends of the flexible bag body by a connecting structure to expand the bag body;

[0006] An elastic support mechanism is provided between the top plate and the bottom plate. The mechanism includes at least two sets of relatively movable support units and elastic elements. The support units are used to maintain the overall frame of the entire storage box, and the elastic elements act on the support units to keep the top plate and the bottom plate at maximum distance to form a storage space.

[0007] An air pump is fixed on a flexible bag body, and a clearance space is provided between the top plate or the bottom plate or the top plate and the bottom plate to allow the air pump to pass.

[0008] When the air pump draws air, the elastic support mechanism overcomes the elastic force of the elastic element under atmospheric pressure and undergoes compression deformation, causing the top plate and bottom plate to translate relative to each other and reduce the distance between them.

[0009] In actual use, after placing the items into the flexible bag, the flexible bag is sealed. Then, the air pump is activated to extract air from the flexible bag, causing it to shrink. The elastic support mechanism undergoes compression deformation, making the top and bottom plates relatively parallel and reducing the distance between them. This reduces the overall volume of the storage box, ultimately completing the folding of the entire storage box.

[0010] The air pump is an existing small electric air pump, which is fixed on the flexible bag and can directly pump air.

[0011] The flexible bag can be sealed using the existing vacuum bag method combined with a zipper sealing strip.

[0012] This solution utilizes a flexible bag body combined with a top and bottom plate and an elastic support mechanism to provide overall support and shaping for the flexible bag. After vacuuming, the bag body will not have any sharp edges, facilitating storage and eliminating safety hazards. Furthermore, because the storage box has a frame shape, it will not excessively compress clothing or blankets, preventing wrinkles. The flexible bag body also features a directly mounted electric vacuum pump, rather than a conventional nozzle, eliminating the need for additional external vacuum devices and making it more convenient.

[0013] Preferably, the air pump is located at the lower end of the flexible bag, the outer wall of the flexible bag is fixedly connected to the bottom plate, and the bottom plate is provided with a through hole, which forms the clearance space.

[0014] The vacuum pump is located on the bottom plate, which can conceal the pump. The clearance hole can limit the position of the pump, and the pump will not move significantly after the bag is evacuated.

[0015] Preferably, the clearance hole fully accommodates the air pump, so that the lower surface of the air pump does not protrude to the outside of the lower surface of the base plate.

[0016] The air pump does not protrude to the underside of the base plate, allowing the base plate to support the ground well and preventing the entire storage box from tilting.

[0017] Preferably, the top plate has a through-hole for placing items, the wall of which is welded or bonded to the outer periphery of the flexible bag, so that the item placement slot directly forms the outline of the bag opening of the flexible bag. The item placement slot can be detachably fitted with a cover plate to seal the bag opening; or

[0018] The flexible bag body has a flexible extension section that extends beyond the item placement slot. The flexible extension section is foldable and has a bag opening and a zipper seal at its top.

[0019] The flexible bag can be sealed by either sealing the slot with a cover plate or by using a zipper seal.

[0020] Preferably, the upper surface of the top plate is provided with a closed area and an open area. The open area is a vertically penetrating item placement slot. The slot wall is welded or bonded to the circumferential outer edge of the flexible bag body, so that the item placement slot directly forms the bag opening boundary outline of the flexible bag body. The item placement slot is detachably equipped with a cover plate that can seal the bag opening. The flexible bag body is provided with the air pump near its bag opening area. The closed area of ​​the top plate is provided with a clearance hole to avoid the air pump. The clearance hole forms the clearance space.

[0021] Placing the air pump on the top plate facilitates user operation. The ratio of the enclosed area to the open area can be 1:2, for example, 1 / 3 is the enclosed area and 2 / 3 is the open area. Furthermore, placing the air pump on the top plate will not interfere with the elastic support mechanism.

[0022] Preferably, the support unit includes at least one set of X-shaped or V-shaped folding rods, and the elastic element is located at the hinge center of the X-shaped or V-shaped folding rod and acts on the X-shaped or V-shaped folding rod to maintain the X-shaped folding rod in its unfolded state; or

[0023] The support unit includes at least one set of telescopic columns, and the elastic element acts on the telescopic columns to maintain the telescopic columns in an extended state.

[0024] Preferably, the air pump is provided on the side wall of the flexible bag body, and the air pump is far away from the telescopic column, so that a clearance space is formed between the top plate and the bottom plate to avoid the air pump.

[0025] Preferably, the X-shaped or V-shaped folding rod is provided on three sides or two opposite sides between the top plate and the bottom plate; the air pump is provided on the side wall of the flexible bag body, and the air pump is located on the side between the top plate and the bottom plate without the X-shaped or V-shaped folding rod, so that a clearance space is formed between the top plate and the bottom plate to avoid the air pump.

[0026] Preferably, the X-shaped or V-shaped folding rod is located on the four sides between the top and bottom plates. When the X-shaped or V-shaped folding rod is folded, the sides of the top and bottom plates have reserved clearance for the air pump; or

[0027] The X-shaped or V-shaped folding rod has a notch on its folding arm. When the X-shaped or V-shaped folding rod is folded, the notch closes to form a clearance space to avoid the air pump; or

[0028] The hinge center of the X-shaped folding rod is provided with an axially penetrating clearance hole, which forms the clearance space, so that the air pump is located within the clearance space.

[0029] Preferably, the top plate and the bottom plate are provided with a plurality of vertically extending abutting protrusions on opposite sides, and when the flexible bag is vacuumed, the abutting protrusions of the top plate and the bottom plate abut against each other.

[0030] The abutting protrusions prevent the top and bottom plates from getting too close, which could cause excessive wrinkling of the compression bag. At the same time, there is enough space between the bottom plates to allow the air pump to pass.

[0031] Compared with the prior art, the beneficial effects of this utility model are: the flexible bag can be directly vacuumed by the vacuum pump without the need for external vacuuming equipment. Furthermore, the flexible bag, combined with the top plate, bottom plate, and elastic support mechanism, provides overall support and shaping for the flexible bag. After being vacuumed, the bag will not have any hard edges, which is conducive to storage and eliminates safety hazards. At the same time, because the storage box has a frame shape, it will not excessively compress clothing or quilts, and clothing and quilts are less likely to wrinkle. Attached Figure Description

[0046] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0047] Example 1

[0048] As shown in Figures 1 to 5, Embodiment 1 discloses a storage box with a vacuum bag, including a top plate 1, a bottom plate 2, and a flexible bag body 3 connecting the two. The flexible bag body 3 can be any existing vacuum bag that can be used for storing clothes or cups. The top plate 1 has a frame structure, and the bottom plate 2 has a solid plate structure. An elastic support mechanism is also provided between the top plate 1 and the bottom plate 2. The elastic support mechanism includes a support unit that can move relative to each other and an elastic element. The support unit is used to maintain the overall frame of the storage box, and the elastic element acts on the support unit to maintain the maximum distance between the top plate 1 and the bottom plate 2, keeping the flexible bag body 3 in an unfolded state to form a storage space. The support element in Embodiment 1 is four sets of X-shaped folding rods 4, which are located on the four sides between the top plate 1 and the bottom plate 2 to support the top plate 1 and ensure that the top plate 1 and the bottom plate 2 are arranged parallel to each other. The central hinge of the X-shaped folding rod has an elastic element (not shown in the figure). The elastic element is an existing torsion spring, which applies a spring force to the X-shaped folding rod to keep it in the unfolded state.

[0049] A vacuum pump 5 is fixedly connected to the bottom of the flexible bag 3. The vacuum pump 5 is an existing small electric vacuum pump, which can have a continuous operating time or be a vacuum pump that needs to be plugged in. The vacuum pump can directly vacuum the flexible bag 3. A through-hole 21 is provided on the bottom plate 2. The through-hole 21 forms a clearance space for the vacuum pump 5. The through-hole 21 completely accommodates the vacuum pump 5, so that the lower surface of the vacuum pump 5 does not protrude to the outside of the lower surface of the bottom plate 2. That is, the lower surface of the vacuum pump 5 can be flush with the lower surface of the bottom plate 2 or the vacuum pump 5 can be retracted into the through-hole 21.

[0050] The top plate 1 has a centrally hollowed-out frame structure with a vertically penetrating item placement slot 11. The slot wall of the item placement slot 11 is welded or bonded to the outer periphery of the flexible bag body 3, so that the item placement slot 11 directly forms the boundary outline of the bag opening of the flexible bag body 3. The item placement slot 11 is detachably equipped with a cover plate 12 that can seal the bag opening. A buckle plate 121 is pivotally connected to the periphery of the cover plate 12. The buckle plate 121 can be fastened to the edge of the top plate 1, thereby realizing the detachable fixation between the cover plate 12 and the top plate 1. A sealing ring (not shown in the figure) is also provided between the cover plate 12 and the top plate 1 to ensure the sealing of the cover plate 12 after sealing the bag opening.

[0051] Vertically extending abutting protrusions 13 are provided at the corners of the top plate 1 and the bottom plate 2 on opposite sides. When the flexible bag body 3 is vacuumed, the abutting protrusions 13 of the top plate 1 and the bottom plate 2 will abut against each other.

[0052] Example 2

[0053] As shown in Figures 6 and 7, the difference between Embodiment 2 and Embodiment 1 is that the air pump 5 of the flexible bag 3 in Embodiment 2 can also be installed on the side wall of the flexible bag 3, and the number of X-shaped folding rods 4 is three sets, respectively located on the three sides between the top plate 1 and the bottom plate 2. The air pump 5 is located on the side without X-shaped folding rods 4. This creates a clearance space between the top plate 1 and the bottom plate 2 to avoid the air pump 5, so that the air pump 5 will not interfere with the X-shaped folding rods when they are folded.

[0054] In some other embodiments, the number of X-shaped folding rods 4 may also be two sets, and they are arranged opposite to each other, that is, arranged on the front and back sides or the left and right sides of the storage box.

[0055] Among them, the X-shaped folding rod 4 can also be a V-shaped folding rod.

[0056] Example 3

[0057] As shown in Figure 8, the difference between Embodiment 3 and Embodiment 2 is that the support unit is a telescopic column 6, which includes at least two interlocking columns. An elastic element (not shown in the figure) is provided inside the telescopic column 6 to maintain its extended state; this elastic element is a conventional compression spring. Both ends of the telescopic column 6 are embedded in the abutment protrusion 13, allowing it to be located away from the air pump 5, preventing the air pump 5 from interfering with the telescopic column 6. This allows the air pump 5 on the flexible bag body 3 to be arbitrarily placed on any side wall of the storage box.

[0058] Example 4

[0059] As shown in Figure 9, the difference between this embodiment 4 and embodiment 1 is that: the upper surface of the top plate 1 is provided with a closed area 14 and an open area (not shown in the figure). The open area is a vertically penetrating item placement slot. The slot wall and the circumferential outer edge of the flexible bag body are welded or bonded with existing hot melt adhesive, so that the item placement slot directly forms the boundary outline of the bag opening of the flexible bag body 3. The item placement slot is detachably equipped with a cover plate 12 that can seal the bag opening. The flexible bag body is provided with an air pump 5 near its bag opening area. The closed area 14 of the top plate 1 is provided with an avoidance hole 21 to avoid the air pump 5. The avoidance hole 21 forms an avoidance space.

[0060] Example 5

[0061] As shown in Figure 10, the difference between this embodiment 5 and embodiment 1 is that the flexible bag body 3 and the item placement slot 11 can be fixed by welding or bonding, or by easy-pull buckles. The flexible bag body 3 has a flexible extension section that extends beyond the item placement slot 11. The flexible extension section can be folded and its top is provided with a bag opening and a zipper sealing strip 31. The zipper sealing strip 31 can control the closing or opening of the bag opening.

[0062] Example 6

[0063] As shown in Figures 11 and 12, in this embodiment 6, there is an X-shaped folding rod 4 or a V-shaped folding rod 7. The top plate 1 and the bottom plate 2 are provided with a sliding groove 8 that cooperates with the X-shaped folding rod 4. The sliding groove 8 is at a certain distance from the corners of the top plate 1 and the bottom plate 2, so that the X-shaped folding rod 4 will leave a certain space to avoid the air pump 5 after folding.

[0064] The hinged end of the V-shaped folding rod is also a certain distance from the corners of the top plate 1 and the bottom plate 2, so that the V-shaped folding rod will leave a certain space to avoid the air pump 5 after folding.

[0065] This allows for clearance between the top plate 1 and the bottom plate 2 to allow the air pump 5 to pass.

[0066] Example 7

[0067] As shown in Figure 13, the housing at the hinge center of the X-shaped folding rod in this embodiment 7 has an axially penetrating clearance hole 21, and an air pump 5 is provided in the clearance hole 21.

[0068] Alternatively, in some other embodiments, the X-shaped folding rod 4 or the V-shaped folding rod 7 has a notch on its folding arm (not shown in the figure). When the X-shaped folding rod 4 or the V-shaped folding rod 7 is folded, the notch surrounds and forms a clearance space to avoid the air pump 5.
