The magnetic component engages with the buoyancy assembly. The magnetic component is configured to provide a magnetic force when the vacuum device and the receiver are assembled together. When the buoyancy device is in the initial position, the magnetic force does not drive the buoyancy device away from the initial position. After the buoyancy device is driven by the liquid flowing out of the container and moves from the initial position to an operating position between the initial position and the clamping position, the magnetic force drives the buoyancy device to move from the operating position to the clamping position in order to clamp the sealing component by the buoyancy device and the housing case to seal the outlet of the housing case.

[0028] Please refer to FIGS. 1 to 4. FIG. 1 is a schematic view 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 container body 111A, a valve seat 112A, and a one-way valve 113A. The container body 111A is configured to store food or any other object. The valve seat 112A is disposed on the container body 111A. The one-way valve 113A is disposed on the valve seat 112A. The vacuum kit 12A is configured to discharge the air inside the container body 111A. The one-way valve 113A is configured to draw out the air inside the container body 111A to the outside of the container 11A through the valve seat 112A and the one-way valve 113A by the vacuum kit 12A, and to prevent the surrounding air from entering the container body 111A through the valve seat 112A.

[0029] In this embodiment, the container body 111A and the one-way valve 113A can be a flexible sealed bag and a sealed one-way valve 113A adhered to the valve seat 112A, respectively. However, the present invention is not limited to this embodiment. For example, in another embodiment, the container body may be a rigid box or a rigid 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 body and the one-way valve may be a flexible sealed bag and a sealed one-way valve directly adhered to the container body, respectively.

[0030] Furthermore, in this embodiment, as shown in FIG. 4, the container 11A is disposed on the valve seat 112A and further includes a filtering component 114A that filters particles to prevent the one-way valve 113A from being damaged by the particles. Specifically, the filtering component 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 component can be omitted.

[0031] Please refer to FIGS. 5 to 10. FIG. 5 is a view of the vacuum kit 12A with the vacuum device 121A removed from the receiver 122A according to the first embodiment of the present invention. FIG. 6 is an internal structure view of the vacuum kit 12A with the vacuum device 121A removed from the receiver 122A according to the first embodiment of the present invention. FIG. 7 is an exploded view of the vacuum kit 12A according to the first embodiment of the present invention. FIG. 8 is a view of the vacuum product 1A with the buoyancy device 1223A located at the initial position K1A according to the first embodiment of the present invention. FIG. 9 is a view of the vacuum product 1A with the buoyancy device 1223A located at the clamp position K3A according to the first embodiment of the present invention. FIG. 10 is a functional block diagram of the vacuum device 121A according to the first embodiment of the present invention. As shown in FIGS. 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 in the container 11A from the container 11A, and a controller 1212A that is electrically connected to the vacuum pump 1211A and is configured to control the vacuum pump 1211A. In this embodiment, the controller 1212A can be a control circuit board. However, the present invention is not limited to this embodiment. The receiver 122A is detachably assembled to the vacuum device 121A. The receiver 122A includes a housing case 1221A, a sealing component 1222A, and a buoyancy device 1223A. The housing case 1221A is configured to be detachably engaged 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 housing case 1221A. The buoyancy device 1223A is movable between the initial position K1A shown in FIG. 8 and the clamp position K3A shown in FIG. 9 with respect to the housing case 1221A. The buoyancy device 1223A includes a buoyancy assembly 12231A and a magnetic component 12232A. The buoyancy assembly 12231A is at least partially movably accommodated in the housing case 1221A. The magnetic component 12232A is engaged with the buoyancy assembly 12231A. The magnetic component 12232A is configured to cooperate with the magnetic attraction component 1213A on the vacuum device 121A to generate magnetic attraction.That is, when the vacuum device 121A and the liquid receiver 122A are assembled to each other, the magnetic component 12232A is configured to generate a magnetic attraction force. The buoyancy device 1223A is driven and moved by the liquid flowing out from the container 11A and / or the magnetic attraction force. As shown in FIG. 8, when the buoyancy device 1223A is located at the initial position K1A, that is, when no liquid is flowing out from the container 11A, due to the excessive distance between the magnetic component 12232A on the vacuum device 121A and the magnetic attraction component 1213A, there is no magnetic attraction force strong enough to overcome gravity, so the buoyancy device 1223A is not driven to move away from the initial position K1A by the magnetic attraction force. During air release, the liquid flowing out from the container 11A can drive the buoyancy device 1223A by buoyancy to move away from the initial position K1A. As shown in FIG. 9, after the buoyancy device 1223A is driven by the liquid flowing out from the container 11A to move from the initial position K1A to the operating position K2A between the initial position K1A and the clamp position K3A, the distance between the magnetic component 12232A on the vacuum device 121A and the magnetic attraction component 1213A becomes shorter, so the magnetic attraction force becomes strong enough to overcome gravity, and the buoyancy device 1223A is driven by the magnetic attraction force to move from the operating position K2A to the clamp position K3A. In order to seal the outlet P2A of the housing case 1221A, the sealing component 1222A is clamped by the buoyancy device 1223A and the housing case 1221A. With such a configuration, it is effectively prevented that the liquid flowing out from the container 11A overflows from the liquid receiver 122A to the vacuum device 121A, and damage to the vacuum device 121A caused by the liquid can be prevented.

[0032] Note that after the vacuum device 121A is removed from the liquid receiver 122A, the buoyancy device 1223A can be driven by gravity to release the seal of the outlet P2A of the housing case 1221A and move away from the clamp position K3A and return to the operating position K2A.

[0033] In this embodiment, the magnetic component 12232A and the magnetic attraction component 1213A can 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 can be a permanent magnet and a ferromagnetic material, respectively.

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

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

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

[0037] In this embodiment, in order to ensure that the buoyancy device 1223A moves from the initial position K1A to the clamp position K3A via the operating position K2A to seal the outlet P2A before the liquid overflows from the second accommodation space S2A, the second buoyancy component B2A can be made of a foaming material. However, the present invention is not limited to this embodiment. For example, in another embodiment, the second buoyancy component 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 in the housing case 1221A and is configured to engage between the vacuum device 121A and the housing case 1221A to prevent leakage from the gap between the vacuum device 121A and the housing case 1221A. The second auxiliary sealing component 1225A is disposed in the housing case 1221A and is configured to engage between the housing case 1221A and the valve seat 112A of the container 11A to prevent leakage from the gap between the housing case 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] Also, as shown in FIGS. 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 is 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, that is, when the sealing component 1222A is clamped by the buoyancy device 1223A and the housing case 1221A, the pressure at the suction end of the vacuum pump 1211A may rapidly decrease. 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 an 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.

A first cooperation structure C1B is formed on the vacuum device 121B, and a second cooperation structure C2B that cooperates with the first cooperation structure C1B is formed on the upper case portion 12211B of the housing case 1221B to facilitate the assembly of the vacuum device 121B and the receiver 122B. The first cooperation structure C1B and the second cooperation structure C2B can be a cooperation recess structure and a cooperation protrusion structure, respectively. A first fitting structure M1B is formed on the lower case portion 12212B of the housing case 1221B, and is configured to cooperate with a second fitting structure formed on the valve seat of the container to align the housing case 1221B with the valve seat of the container. An inlet P1B of the housing case 1221B is formed on the lower case portion 12212B of the housing case 1221B, and an outlet P2B of the housing case 1221B is formed on the upper case portion 12211B of the housing case 1221B.

The buoyancy device 1223B is movable relative to the housing case 1221B between the initial position K1B shown in FIG. 13 and the clamp position K3B shown in FIG. 14 via the operating position K2B shown in FIG. 14.When the buoyancy device 1223B is located at the clamp position K3B shown in FIG. 14, the sealing component 1222B is clamped by the buoyancy device 1223B and the housing case 1221B to seal the outlet P2B of the housing case 1221B.

[0041] The buoyancy device 1223B includes a buoyancy assembly 12231B and a magnetic component 12232B. The buoyancy assembly 12231B is movably received in a receiving space SB of the housing case 1221B defined by an upper case portion 12211B and a lower case portion 12212B of the housing case 1221B. The buoyancy assembly 12231B includes a first buoyancy component B1B and a second buoyancy component B2B detachably assembled to the first buoyancy component B1B. The second buoyancy component B2B is formed in a disc shape, and the first buoyancy component B1B includes a main body portion B11B and an extending portion B12B. The main body portion B11B of the first buoyancy component B1B is located on the side of the second buoyancy component B2B away from the inlet P1B of the housing case 1221B and is for abutting against the sealing component 1222B. The extending portion B12B of the first buoyancy component B1B extends from the main body portion B11B of the first buoyancy component B1B toward the inlet P1B of the housing case 1221B and penetrates the second buoyancy component B2B. The magnetic component 12232B engages with the first buoyancy component B1B and is at least partially disposed inside the proximal end of the extending portion B12B of the first buoyancy component B1B adjacent to the main body portion B11B of the first buoyancy component B1B for cooperating with the magnetic attraction component 1213B of the vacuum device 121B. A guide structure GB is formed on the lower case portion 12212B of the housing case 1221B and is configured to cooperate with the extending portion B12B to guide the buoyancy assembly 12231B back to the initial position K1B.
