[0027] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof, and which illustrate specific embodiments in which the invention may be practiced. In this regard, directional terms such as "upper," "lower," "left," "right," "front," "rear," etc. are used with reference to the orientation of the views being described. Components of the invention can be positioned in many different orientations. Accordingly, the directional terminology is used for purposes of illustration and not of limitation. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

[0028] Please refer to FIGS. 1 to 4. FIG. 1 is a schematic diagram of a vacuum product 1A according to a first embodiment of the present invention. FIG. 2 is an exploded view of the vacuum product 1A according to the first embodiment of the present invention. FIG. 3 is an exploded view of a container 11A according to the first embodiment of the present invention. FIG. 4 is a partial cross-sectional view of the container 11A according to the first embodiment of the present invention. As shown in FIGS. 1 to 4, the vacuum product 1A includes a container 11A and a vacuum kit 12A. The container 11A includes a housing 111A, a valve seat 112A, and a one-way valve 113A. The housing 111A is configured to store food or any other object. The valve seat 112A is disposed in the housing 111A. The one-way valve 113A is disposed in the valve seat 112A. The vacuum kit 12A is configured to exhaust air from the housing 111A. The one-way valve 113A is configured by the vacuum kit 12A to draw air from the container 11A out of the container 11A through the valve seat 112A and the one-way valve 113A, while preventing ambient air from entering the container 111A through the valve seat 112A.

[0029] In this embodiment, the container 111A and the one-way valve 113A may be a flexible sealed bag and a sealed one-way valve 113A attached to the valve seat 112A, respectively. However, the present invention is not limited to this embodiment. For example, in another embodiment, the container may be a hard box or a hard jar, and the one-way valve may be a rubber umbrella valve. Alternatively, in another embodiment, the valve seat may be omitted, and the container and the one-way valve may be a sealed one-way valve attached directly to the flexible sealed bag and the container, respectively.

[0030] 4, the container 11A further includes a filtering element 114A disposed on the valve seat 112A for filtering particles to prevent the one-way valve 113A from being damaged by particles. Specifically, the filtering element 114A is made of a mesh fabric and can be disposed on the valve seat 112A by overmolding. However, the present invention is not limited to this embodiment. For example, in another embodiment, the filtering element can be omitted.

[0031] Please refer to Figures 5 to 10. Figure 5 is a diagram of a vacuum kit 12A according to a first embodiment of the present invention, with the vacuum device 121A removed from the receiver 122A. Figure 6 is a diagram of the internal structure of a vacuum kit 12A according to a first embodiment of the present invention, with the vacuum device 121A removed from the receiver 122A. Figure 7 is an exploded view of a vacuum kit 12A according to a first embodiment of the present invention. Figure 8 is a diagram of a vacuum product 1A according to a first embodiment of the present invention, with the buoyancy device 1223A located in an initial position K1A. Figure 9 is a diagram of a vacuum product 1A according to a first embodiment of the present invention, with the buoyancy device 1223A located in a clamp position K3A. Figure 10 is a functional block diagram of a vacuum device 121A according to a first embodiment of the present invention. As shown in Figures 5 to 10, the vacuum kit 12A includes a vacuum device 121A and a receiver 122A. The vacuum device 121A includes a vacuum pump 1211A that draws air from the container 111A and a controller 1212A electrically connected to the vacuum pump 1211A and configured to control the vacuum pump 1211A. In this embodiment, the controller 1212A may be a control circuit board. However, the present invention is not limited to this embodiment. The receiver 122A is detachably attached to the vacuum device 121A. The receiver 122A includes a container case 1221A, a sealing component 1222A, and a buoyancy device 1223A. The container case 1221A is configured to detachably engage with the valve seat 112A and includes an inlet P1A and an outlet P2A. The sealing component 1222A is disposed adjacent to the outlet P2A of the container case 1221A. The buoyancy device 1223A is movable relative to the housing 1221A between an initial position K1A shown in FIG. 8 and a clamped position K3A shown in FIG. 9. The buoyancy device 1223A includes a buoyancy assembly 12231A and a magnetic component 12232A. The buoyancy assembly 12231A is at least partially movably housed within the housing 1221A. The magnetic component 12232A is engaged with the buoyancy assembly 12231A. The magnetic component 12232A is configured to cooperate with a magnetic attraction component 1213A on the vacuum device 121A to generate a magnetic attraction force.That is, the magnetic component 12232A is configured to generate a magnetic attractive force when the vacuum device 121A and the receiver 122A are assembled together. The buoyancy device 1223A is driven to move by the liquid flowing out of the container 11A and / or the magnetic attractive force. As shown in FIG. 8 , when the buoyancy device 1223A is located at the initial position K1A, i.e., when no liquid is flowing out of the container 11A, the distance between the magnetic component 12232A on the vacuum device 121A and the magnetic attractive component 1213A is too long, and therefore the magnetic attractive force is insufficient to overcome gravity, and the buoyancy device 1223A is not driven away from the initial position K1A by the magnetic attractive force. During air release, the liquid flowing out of the container 11A can drive the buoyancy device 1223A away from the initial position K1A by buoyancy. 9, the buoyancy device 1223A is driven by the liquid flowing out of the container 11A to move from the initial position K1A to the operating position K2A between the initial position K1A and the clamping position K3A. Then, as the distance between the magnetic component 12232A on the vacuum device 121A and the magnetic attraction component 1213A becomes shorter, the magnetic attraction becomes strong enough to overcome gravity, and the buoyancy device 1223A is driven by the magnetic attraction to move from the operating position K2A to the clamping position K3A. The sealing component 1222A is clamped by the buoyancy device 1223A and the container 1221A to seal the outlet P2A of the container 1221A. This configuration effectively prevents the liquid flowing out of the container 11A from overflowing from the receiver 122A into the vacuum device 121A, preventing damage to the vacuum device 121A caused by the liquid.

[0032] After the vacuum device 121A is removed from the receiver 122A, the buoyancy device 1223A can be driven by gravity to unseal the outlet P2A of the container 1221A, leaving the clamped position K3A and returning to the operating position K2A.

[0033] In this embodiment, the magnetic component 12232A and the magnetic attraction component 1213A may be two permanent magnets. However, the present invention is not limited to this embodiment. For example, in another embodiment, the magnetic component 12232A and the magnetic attraction component 1213A may be a permanent magnet and a ferromagnetic material, respectively.

[0034] To facilitate engagement between the housing 1221A and the valve seat 112A, as shown in FIGS. 2-4 and 6-9, a first mating structure M1A is formed on the housing 1221A, and a second mating structure M2A is formed on the valve seat 112A. The second mating structure M2A is configured to cooperate with the first mating structure M1A to align the housing 1221A and the valve seat 112A. In this embodiment, the first mating structure M1A may be a mating recess structure, and the second mating structure M2 may be a mating protrusion structure configured to be inserted into the first mating structure M1A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first mating structure and the second mating structure may be a mating protrusion structure and a mating recess, respectively.

[0035] To facilitate assembly of the vacuum device 121A and the receiver 122A, as shown in FIGS. 5-7, the vacuum device 121A is formed with a first cooperating structure C1A, and the housing 1221A is formed with a second cooperating structure C2A that cooperates with the first cooperating structure C1A. In this embodiment, the first cooperating structure C1A may be a cooperating recess structure, and the second cooperating structure C2A may be a cooperating protrusion structure configured to be inserted into the first cooperating structure C1A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first cooperating structure and the second cooperating structure may be a cooperating protrusion structure and a cooperating recess structure, respectively.

[0036] Furthermore, as shown in FIGS. 6 to 9, a first storage space S1A and a second storage space S2A are formed in the casing 1221A. The inlet P1A communicates with the first storage space S1A, and the outlet P2A communicates between the first storage space S1A and the second storage space S2A. Liquid flowing out of the container 11A flows into the first storage space S1A through the inlet P1A, and when the outlet P2A is unsealed, it can flow into the second storage space S2A through the outlet P2A. The sealing component 1222A is disposed on a wall portion of the casing 1221A and is located adjacent to the first storage space S1A. The buoyancy assembly 12231A includes a first buoyancy component B1A and a second buoyancy component B2A detachably attached to the first buoyancy component B1A. The second buoyant component B2A is disc-shaped and is received in the second housing space S2A. The first buoyant component B1A includes a main body portion B11A and an extension portion B12A extending from the main body portion B11A and penetrating the second buoyant component B2A. The main body portion B11A is received in the first housing space S1A and configured to abut against the sealing component 1222A. That is, the main body portion B11A is located on a side of the second buoyant component B2A closer to the entrance P1A of the housing case 1221A, and the extension portion B12A extends from the main body portion B11A away from the entrance P1A of the housing case 1221A. The magnetic component 12232A is at least partially disposed within the distal end of the extension portion B12A of the first buoyant component B1A, away from the main body portion B11A.

[0037] In this embodiment, the second buoyant part B2A can be made of a foam material to ensure that the buoyant device 1223A moves from the initial position K1A to the clamped position K3A via the actuated position K2A to seal the outlet P2A before the liquid overflows from the second accommodation space S2A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the second buoyant part B2A can be a plastic pontoon.

[0038] As shown in FIGS. 6 to 9 , the receiver 122A preferably further includes a first auxiliary sealing component 1224A and a second auxiliary sealing component 1225A. The first auxiliary sealing component 1224A is disposed on the housing 1221A and configured to engage between the vacuum device 121A and the housing 1221A to prevent leakage from a gap between the vacuum device 121A and the housing 1221A. The second auxiliary sealing component 1225A is disposed on the housing 1221A and configured to engage between the housing 1221A and the valve seat 112A of the container 11A to prevent leakage from a gap between the housing 1221A and the valve seat 112A of the container 11A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first auxiliary sealing component may be disposed on the vacuum device, and the second auxiliary sealing component may be disposed on the valve seat. Alternatively, in another embodiment, at least one of the first auxiliary sealing component and the second auxiliary sealing component may be omitted.

[0039] 7 and 10, in this embodiment, the vacuum device 121A further includes a pressure sensor 1214A. The pressure sensor 1214A is electrically connected to the controller 1212A and configured to detect the pressure at the suction end of the vacuum pump 1211A. When the buoyancy device 1223A is in the clamp position K3A, i.e., when the sealing part 1222A is clamped between the buoyancy device 1223A and the casing 1221A, the pressure at the suction end of the vacuum pump 1211A may suddenly drop. When the pressure at the suction end of the vacuum pump 1211A detected by the pressure sensor 1214A reaches a predetermined low pressure, the controller 1212A can stop the vacuum pump 1211A to prevent overload of the vacuum device 121A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the pressure sensor can be omitted.

[0041] The buoyancy device 1223B includes a buoyancy assembly 12231B and a magnetic component 12232B. The buoyancy assembly 12231B is movably received in an accommodation space SB of the accommodation case 1221B, which is defined by an upper case portion 12211B and a lower case portion 12212B of the accommodation case 1221B.
