[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] The embodiments of this utility model relate to a vacuum-sealed suitcase, such as... Figures 1-2 As shown, the luggage includes a first box 1, with a second box 2 hinged to one side of the first box 1. The first box 1 is made of sealing material and has a first inner cavity 11 inside. A connecting part 3 is sealed along the edge of the opening of the first inner cavity 11. A sealing film 5 is disposed on the upper side of the connecting part 3. The sealing film 5 and the connecting part 3 are made of flexible high-strength composite material, which is not easily damaged by repeated folding and extends its service life. The sealing film 5 and the connecting part 3 are connected by a zipper 4. A one-way valve 6 for venting is provided on the upper surface of the sealing film 5. When the zipper 4 is closed, a sealed storage space is formed between the sealing film 5, the connecting part 3 and the first inner cavity 11. Through the sealed space formed by the sealing film 5 and the connecting part 3, combined with the one-way valve 6, clothing can be quickly vacuumed and compressed, reducing the volume occupied and improving the utilization rate of the luggage capacity, which is especially suitable for long-distance travel or the storage of large items.
[0019] In this embodiment, as Figure 1 As shown, the first box 1 is made of ABS or PC material. The first box 1, which is integrally injection molded from ABS or PC material, has no splicing seams, good sealing performance, and also takes into account lightweight and impact resistance.
[0020] In this embodiment, as Figure 2 As shown, magnetic strips 7 are provided on the inner sides of the sealing film 5 and the connecting part 3 at opposite positions. Before the sealing film 5 and the connecting part 3 are closed by the zipper 4, the magnetic strips 7 attract each other to seal. When the sealing film 5 is placed on the connecting part 3, the magnetic strips 7 automatically attract and fix it, realizing the initial positioning of the sealing film 5 and the connecting part 3, which facilitates the precise closure of the zipper 4. The magnetic strips 7 also improve the sealing effect.
[0021] In this embodiment, as Figure 1 As shown, the second box 2 is provided with a second inner cavity 21. The volume of the second inner cavity 21 is smaller than that of the first inner cavity 11. When the items in the first inner cavity 11 are compressed, more items can be placed in the space between the second inner cavity 21 and the upper side of the sealing film 5.
[0022] In this embodiment, as Figure 1 As shown, the connecting part 3 and the inner wall of the first housing 1 are sealed together by heat fusion to form a strong and airtight connection, which effectively prevents air from leaking between the housing and the connecting part.
[0023] In this embodiment, as Figure 1 As shown, the zipper 4 is a sealed zipper, and a silicone-based sealing grease layer is provided on the surface of the zipper teeth, which can provide a better sealing effect, prevent air from entering the closed storage space, and ensure the compression effect.
[0024] In this embodiment, as Figure 1 As shown, the connecting part 3 and the sealing film 5 are composed of multiple layers of film. By using the multilayer film structure, the quality and service life of the connecting part 3 and the sealing film 5 are improved.
[0025] In this embodiment, as Figure 1 As shown, the connecting part 3 and the sealing film 5 are made of a three-layer co-extruded film of TPU / EVOH / TPU. The outer TPU layer has excellent tensile strength, tear strength and wear resistance, and can withstand the friction and impact during frequent use, ensuring the durability of the connecting part and the sealing film. The middle EVOH layer can block oxygen and water vapor. The elasticity and flexibility of the inner TPU layer allow it to fit well with parts of different shapes, ensuring the sealing effect and preventing gas leakage.
[0026] In this embodiment, as Figure 1 As shown, the connecting part 3 and the sealing film 5 are made of PA / PE co-extruded film. The PA layer provides excellent tensile strength and puncture resistance, while the PE layer enhances flexibility and tear resistance, preventing microcracks from forming after repeated folding.
[0027] In this embodiment, as Figure 1 Figure 1 As shown, place the clothing to be compressed into the first inner cavity 11, cover the connecting part 3 with the sealing film 5, and the magnetic strip 7 will automatically adhere to it, initially fixing the sealing film 5. Pull and close the zipper 4, and a sealed storage space is formed between the sealing film 5, the connecting part 3, and the first inner cavity 11. Connect the suction nozzle of the air pump to the one-way valve 6. The one-way valve 6 is used to ensure that the air inside the storage space can only be discharged outwards, and that outside air cannot enter the closed storage space. Start the air pump to extract the gas from the closed storage space. When the required compression level is reached, the sealing film 5 and the connecting part 3 will be in contact with the items, thereby binding the items. Turn off the air pump and disconnect the connection, close the second box 2, and the operation is complete.
